771. How are eye injuries treated at Toa Payoh Vets

HOW ARE EYE INJURIES TREATED AT TOA PAYOH VETS?

Dr Sing Kong Yuen, BVMS (Glasgow).

 1. General examination of the dog and eyes. 

2. Detailed examination of the eye injury.

3. Pupil examination - Pupillary light reflex - direct and consensual.

4. Cornea examination - Fluorescein stain strip on both eyes and inform owner of the extent of the green stain.

5. Record and illustrate extent of ulcers (green stain) and advices on treatment in the medical record. 

6. Diagnosis – For example, superficial keratitis, ulcerative keratitis, descemotocoele as shown in images below.

7. Advices on treatment and costs.

7.1 Extremely itchy eye. E-collar and eye drops. Eye irrigation of 3rd eyelid if acute conjunctivitis, under sedation is strongly advised.

7.2 Corneal ulceration surgery. Tarsorrhaphy under general anaesthesia. 

7.3 Corneal ulceration surgery. Tarsorrhaphy and 3rd eyelid flap under general anaesthesia.


7.4 Corneal ulceration surgery. Conjunctival graft. Needs 7/0 sutures under general anaesthesia.

8. Digital images before & after treatment preferred or illustration to be recorded in the medical record.

9. Post-op warding in Toa Payoh Vets for 3 days mandatory for tarsorrhapy and conjunctival flap. Owners who insist on bringing the dog home are strongly advised not to do so. The "Against Medical Advice" instruction is to be clearly recorded in the medical record to avoid disputes of post-op stitch breakdown. 

10. Pre-op preparation for surgery. Ensure area is shaved clean. Bigger facial area to be clipped short on both eye area. Eye lashes to be clipped short. 

11. Eyelid eversion and irrigation must be done.

12. Sub-conjunctival injection of gentamycin may or may not be done, depending on the vet. 

13. Advices: Treat the cause of corneal ulcerations. Traumatic injury caused by the protruding eyeball in the Shih Tzu, Pug, Pekinese ensures that such eye injury cases are common in the three above mentioned breeds in Singapore and elsewhere. Another cause is nasal fold hairs irritating the eyeball and nasal fold excision surgery is recommended. Ectopic cilia is another cause of eye corneal irritation and ulceration.

EYE INJURIES




Superficial ulcerative keratitis 



Deep ulcerative keratitis (blood and fluid seen)




Descemetocoele (protrusion of the eye basement membrane)




SURGICAL TREATMENT
Tarsorrhaphy is the joining of part or all of the upper and lower eyelids so as to partially or completely close the eye. Temporary tarsorrhaphies are used to help the cornea heal or to protect the cornea during a short period of exposure or disease. The procedure is done at Toa Payoh Vets. Images of a case study is shown below.










EYELID IRRIGATION
Eyelid eversion is used to expose the superior palpebral conjunctiva and fornix, so that foreign matter can be identified in these areas. Eyelid eversion and irrigation are frequently done together to ensure that both particulate material and chemical irritants are removed from the entire ocular surface. 





SURGICAL TREATMENT
Conjunctival graft. A strip of conjunctiva is freed and rotated so that it covers the ulcer, then stitched into position using very fine dissolvable suture material. The conjunctival graft provides a blood supply and physical support to the ulcer to allow it to heal.

Typically, the cornea will heal in 6 to 8 weeks. A follow-up appointment is necessary to monitor your pet's healing.

770. A cat with stinky right ear

"The right ear is very smelly. Have you considered ear irrigation?" I asked the lady whose cat scratched her whenever she tried to put ear drops into the right ear. "The vets gave me the ear drops and asked me to do it," she said. "But I can't do it."
So she consulted me as the problem had become worse.

As vets, we often prescribe ear drops and ask the cat owner to do it herself and often they manage. Owners who consult us again when they can't do it should be advised about ear irrigation. Otherwise the owner just go to another vet for a solution to her cat's ear problem.


"If ear irrigation fails to resolve the problem, there is the ear canal opening surgery," I said. "We will try ear irrigation first and see if it works."

The 4-kg cat was given xylazine 0.1 and ketamine 0.4 ml IM in one injection. The day before, I gave him 50% of the above formula and it didn't work. Sedation was given as low as possible as this cat was not in good health due to the chronic ear infection and it is always good to be careful.

"In ear irrigation, there must be a correct way of irrigation. Otherwise, nothing would be flushed out of the ear canal," I said to my assistant Min. I demonstrated to him my technique. He could see the big brown mass appeared out of the ear canal. I took a picture in case the cat owner was interested as Min did not keep the "evidence".



When the owner took the cat home, I said: "The cat had a lot of dead cells and wax flushed out of the ear canal. You will need to use this ear ointment to continue."

An ear ointment again? From a vet again? The lady shook her head. Why can't the vet understand that her cat would scratch her. Didn't the vet listen sufficiently?

"The ear ointment is to be applied 2 weeks later," I soothed her anxieties of being scratched. "The drugs and injection would bring down the pain, swelling and infection and you should have no problem applying the ear ointment to clear any leftover infection."

She left and I had not heard from her for over one week. If I don't see her again, I presume all are OK. Unless she went for a 4th opinion. I ought to phone her to follow up.

769. Sunday's interesting case. Post-op spay swelling

Sunday Dec 11, 2011

1. Post-spay complications do occur now and then to all vets performing spays in female dogs. It is hard to prevent every case.

Post-op 7 days later, an active Jack Russell came with swelling and inflammation at the spayed area. It looked as if the dog had irritated the spayed area due to itchiness as the owner said he had never taken out the e-collar. The dog was warded. There was no complaint till recently. The dog had pain-killers and antibiotics post-op.

2. 18-year-old cat with 2 large sores on back spinal area. "Would you advise euthanasia?" the owner asked me. "This cat was paralysed last year and treated by you," the owner said. "He could walk later."
"How long it took to walk normally?" I recorded injury T10-L3, jumped upon by the Golden Retriever. I was much surprised that he could be alive.
"A year of walking on front legs and then all 4 legs,.

"It is up to the owner to decide," I said. "Is the cat eating?"
The owner said: "Yes,".
"Many times it will be the children who are against euthanasia," I said.
"No euthanasia," the pre-teen child who listened intenly decided.
I don't advise euthanasia and it should be the owner's decision as treatment may or may not cure. But euthanasia denies a chance of living.
Gave the old cat a warm bath after Min had clipped bald. Got a kettle of water boiled and bathe this aged feline who went into fits when I touched the two big scabs on his back, somewhere on either side of the T10-L3 area Had fleas. Needed grooming and ear cleaning.


3. 4-year-old Schnauzer with globular skin tumour around 8mm x 8mm on right neck
"Any drugs to make it disappear?" the lady in her 30s asked me.
"Not advised," I said. "This is a skin growth. It may or may not be cancerous."
"How much?"
"Anaesthesia and surgery and medication estimated around $250," I said. "Do you want to know whether it is cancerous or not. If you want to know, I will send to the lab for histopathology."
"What if the growth is cancerous?" the husband asked. "Is there a cure?"
"It is not guaranteed," I said. "Depends on type of malignancy."
So, it was decided that the lump be removed and dental scaling be done at the same time to save on costs.

4. Paralysed Shih Tzu.
This Shih Tzu could lift his head but would not stand on his four legs as 2 days ago. His tongue was peculiarly a dark pinkish red. I took him outside the Surgery at 1.10 pm for review. He peed, looked at me. Later he pooped a large amount of soft brown black stools.
Same eye reflex as before when I shone the bright light on both eyes. The left one was dilated while the other constricted on light shone on the pupils. The left one dilated lesser amount than 2 days ago. I asked Dr Vanessa to pinch the front toes of both front paws. Both paws showed withdrawal reflex.

Blood sample taken to check for infection. Glucose, duphalyte and IV drip given. "It takes a long time to recover," I said to Dr Vanessa. "It is not going to be so soon."

768. Dietary management to dissolve struvite stones in the dog - no surgery

Below is an update of what I wrote from Perth in Sep 2010 when I was there on holiday and sat down to read the very thick book "Small Animal Clinical Nutrition" far away from the distractions of practice in Singapore.

The website is at:
http://www.sinpets.com/F5/20100697struvite-dietary-management-voiding-urohydropropulsion_ToaPayohVets.htm

The following is copied from the website:


After the surgical removal of the struvite urinary stones or for medical and dietary treatment, how much of the prescription diet should the owner give the dog/day?

I took some time just to read about Canine Struvite Urolithiasis case studies in the sleep-inducing thick book "Small Animal Clinical Nutrition" by Hand et. al, 5th Edition while on holiday in Perth, Australia. The following is some general guideline for Toa Payoh Vets in advising on Prescription Diet s/d to dogs based on 3 case studies in the book.

How much of the s/d diet to be given?
1. Puppy X-breed, 9 weeks,
5 kg.
700kcal (2.83MJ)
1/2 can 3x/day
2. Rottweiler, 5 years, 41 kg
1,800kcal (7.5MJ)
1.5 cans 2x/day
3. German Shepherd, 12 years, 27 kg
1,150kcal (4.8MJ)
1 can 2x/day
Other procedures to ensure compliance from the owner:
1. Antibiotics from 14-30 days and review using urine cultures
2. Monthly urine analysis (check for UTI) and blood tests (esp. serum urea nitrogen, magnesium, phosphorus and calcium and alkaline phosphatese)
3. Monthly x-rays of kidney (V/D view), bladder (lateral views).

Back to normal commercial food for the puppy as soon as X-rays show no stones. For adult dogs, give prescription food for one more month after negative X-ray results. No commercial dog treats or snacks during the period of treatment. In practice, I advise initially 3 months of the S/D diet and get urine tests done monthly in most cases. The Singapore dog owner seldom complies with the above-mentioned procedures or with monthly urine tests! Till blood in the urine returns!

RECURRENT UTI
Specialised tests like double-contrast cystography (to check out anatomic abnormalities of the bladder, obstruction of urine flow from kidneys), retrograde positive-contrast urethrocystography (to check out anatomical abnormalities of the urinary tract to the prostate gland area, bladder tumours) if there is recurrent uroliths or UTI (see case study of the old Corgi with recurrent UTI.


Recurrent UTI in an old Corgi - Part 1 http://www.sinpets.com/dogs/20111044blood-urine-recurs-over10times-old-corgi-female-toapayohvets.htm






http://www.sinpets.com/F6/20111210recurrent-urinary-tract-infection-old-female-spayed-corgi-singapore-toapayohvets.htm


Voiding urohydropropulsion is used in cases where the uroliths are small. The owner must be informed that it takes 2-4 months or longer to get all struvite stones dissolved. The owner must be aware of the need for reviews and to note the costs involved in the dietary management to dissolve struvite urinary stones.
VETERINARY SURGERY --- VOIDING UROHYDROPROPULSION IN DOGS AND CATS

What is urohydropropulsion? Basically it means pumping saline into the bladder (3ml/kg) and suck out the fluid together with the small uroliths (urinary stones) with a catheter. The stones in the bladder are too small and therefore no surgical removal is needed.

ANAESTHESIA. May or may not be need.
APPROACHES. Two methods described in Small Animal Clinical Nutrition 5th edition.

POSITION 1. Hold the dog or cat upright so that the vertebral column is upright. The urine and stones will be at the bottom (neck) of the bladder.
POSITION 2. Lateral recumbency.

In both positions, catheterise, irrigate with saline (3ml/kg), massage or press bladder to shake up the stones, suck out the saline + stones with a syringe. X-rays to check if all are taken out but not all small ones can be seen.

Dietary and medical treatment.

767. No more smelly urine after the end of antibiotics for an old corgi

On Friday Dec 9, 2011, at 11.40 am, I was in the consultation room facing Dr Vanessa and Mr Min on the other side of the consultation table. I conducted a meeting regarding work performance to ensure that the quality of veterinary service is up to my standard and to be free of clientele complaints.

"In many companies, there is a monthly meeting to discuss work matters like problems and solutions," I said to both of them. "I don't do it monthly as I expect both of you to do your part and to adopt my advices for changes. However, I have to discuss with both of you work matters today."

One of the topics I spoke about was the need for direct eye-contact with clients to connect well.

"When a client comes into the consultation room, stand up and greet him, rather than sit down and look up to him," I said. "You may be tired but still this is the proper way to do. You may get a chair and ask the client to sit down if you wish to sit down to discuss the dog's health. I always stand up to greet the client throughout my years of practice or invite them to sit. There was a complaint of one unfriendly vet who sat down and looked up at the client...."

I illustrated with my personal anecdotes and gave my tips as how to handle several cases by Dr Vanessa and Min who is a vet from Myanmar.

As regards examination of the severely "paralysed" recumbent panting dog that came in yesterday as a second opinion, the important things to do would be to collect blood and urine samples first, before any treatment like IV drip. If the owner objected to it due to the fact that Vet 1 had just done the blood test, record this objection, time and name of the owner. "The dog was diagnosed as having spinal injuries by Vet 1. How do you know whether the dog at the time of arrival half dead and panting and unable to stand up was also suffering from hypoglycaemia which would be obvious from a simple blood test?" This morning, I took the dog outside for a review and he was walking unsteadily as he had been given IV drip, painkillers and frequent feeding.

I said: "A quadriplegic dog with a cervical fracture or dislocation would not be able to walk at all. In addition, there is no rush to do an X-ray which was done yesterday as the dog's head was twisted and the X-ray views were not so good," I said. "Go back to basics of neurology. A quadriplegic dog cannot normally be having spinal problems in the lumbo-sacral area as the brain stem and cervical spinal area would be the likely area of traumatic injury. It is possible that there is injury in the tail spinal area as evident by the presence of pain on palpation, but the primary diagnosis should be the brain stem and cervical area.

"Stabilise the dog, give the IV and medication and take the neck X-ray later in cases where the dog had a twisted neck on admission." We all learn by experiences of handling a case and that include me even though I have practised for over 40 years. This was an unusual case. The dog could put weight on the right fore but limped on the other 3 legs. What was he suffering from? Was it head concussion, bleeding and traumatic injury as I suspected? A kick to the side of the head. So, the right eye pupil constricts on direct light but the left eye pupil does not constrict and is dilated even this morning. Yet he can stand up on his own on the right fore limb and walk a distance like a drunken. I am still suspecting a brain stem injury and am reviewing this mysterious case.

P.S. In the evening, the lady and her husband who read on the internet about IVDD (intervertebral disc disease) came after work. I was still around as I booked in a 6-week-old male guinea pig for neutering and showed another Shih Tzu with eye injury in to Dr Vanessa's room for her to treat.

As for the couple, I placed their Shih Tzu on the table and shone bright lights onto each eye. The left eye pupil was dilated despite the bright light. The right eye pupil was constricted. I said to the couple: "This showed that the left eye does not have a direct pupillary response to light." As for consensual pupillary response, the left eye does not constrict even when the bright light was shone onto the right eye.

So, the left eye also did not have consensual pupillary response. The neurological explanation will sound too technical to the owners and so I did not want to confuse them by elaborating.

"Basically, I would say that the traumatic injury is around the brain stem," I said. "The X-rays showed two microchips. One was on top of the cervical spinal bone. Whether this would cause the present problem, I do not know. The other one was in the armpit area.

However, the dog could put weight on the right fore limb and this morning, he could walk upright or limped a distance of over 5 metres before collapsing," I said. I pinched the toes of all 4 limbs in front of the couple. Only the left fore limb had no withdrawal to pinching reflex pain sensation. In veterinary practice, showing is communication to the owner as nowadays, the young Singaporeans are so much more sophisticated.

"There is some improvement," I said and the couple could see it too. "We feed the dog around 4 times a day and give the necessary vitamins. He can't eat on his own. He has got the energy and alertness now. But he needs complete rest and so please do not stay long." The couple adjusted the water bottle height and reluctantly left at 7.30 pm.

A HAPPY LADY IN RED CAME TO THE SURGERY

A fair lady in red sheath dress, with black eyeliner suddenly came into the waiting room and waved at me from the outside. My consultation room's door has a glass window on the top half and so I could see who was coming into the waiting area. This lady, in her prime at around early 30s, looked quite familiar and since she waved to me, she must have met me. I had to stop the meeting which had taken over 30 minutes as I guess my assistants had enough of my reiterations of things to do, government and legal processes to be complied with and records to be written meticulously. Reminders to staff appear to be part of a manager's job and it is a role I rather not be involved in. But I was the licensee and the ultimate responsibility of any clientele complaint, investigation and litigation is with the licensee.

I said hi to the lady in red. Fairness and bright red always demand attention. The lady in red said: "Do you remember the Corgi? I am coming for the S/D diet."

"I am sorry I can't recognise you," I said. "But I do remember Oreo. She had seen a few vets and always passed smelly urine after a course of antibiotics. For at least 2 years or so. Is she OK now?" I had thought of following up but had not done so and now one month had flown by. Just like that.

"Well," the lady beamed. "She is no longer passing smelly urine after one month of treatment. Your medication has been taken and is no more. Her urine is clearer. Best of all, I don't have any smelly urine in the apartment after the end of antibiotics as in the past."

"How many times does Oreo pee and how much does she drink per day?" I asked. "Did you measure the amount of water she drinks a day?" It was difficult for her to answer precisely as she did not take note. She said: "I can't measure the amount because Oreo drinks only fresh water and so the bowl of left over water has to be replaced."

I was surprised that her female spayed dog peed all over the apartment at such an old age. "An adult dog usually pees twice a day, in most cases," I said. "The fault lies with the owner if she pees many times a day," I said. "The owner has no properly house-training the dog as a puppy." This frankness was not good bedside manners.

"Well, I did," she said. "She would hold her urine and then let go a lot." She spread her arms wide. "Is it common for dogs to pass a vast amount of urine every day"

"A dog would pass a lot of urine in the morning for one time," I said. "But not several times. Your dog has been withholding the urine until she can't stand it anymore. You must be beating her up when she had peed all over the apartment when she was younger," I said. "Holding urine leads to bladder infection and the smelly urine that the various vets you consulted before could not cure. Your dog is not fully cured yet. It is only one month.

"You need 3 months of S/D diet to know whether she will be free of urinary tract infection as the S/D diet acidifies the urine and prevents bacteria forming struvite sand in the bladder, leading to bad smelly urine. No other food, dog treats or any other pills."

"My dog loves apples," she said. "Can I give her apples? She looks at me appealingly for apples when I eat one."

"It is best not to," I said. "You had suffered over 2 years of this problem of smelly urine after antibiotics after seeing a vet. Now, her urine is not smelly without antibiotics. Why take risks? Let her urinary tract system stabilise over 3 months of eating S/D diet and drinking plain water. Then you may give her apples."

As regards whether the Corgi was harshly disciplined when she was younger, the lady in red said: "Yes, she got spanked when she peed everywhere." the lady said. "This may be why she withholds her urine till the last moment and urinated a very large puddle of urine onto the floor. What do you suggest I do now?"

At first I advised confinement and removing the urine smell in the floor apartments using white vinegar + water at 1 part to 3 parts water.

As she was moving to a new apartment away from Woodlands soon, I advised: "Complete confinement for 24 hours in a room, with a baby gate, for 4-6 weeks. Newspapers with her urine smell on one side and bed on the other. Confinement is the key to success. Let the dog out when you are at home and pick her up when she is about to pee on the floor and put her into the confined area. Say in a firm tone 'Pee here.' Give a treat if she does that or a praise. Persevere. Old dogs can learn new tricks too especially when you start from a new house."

This case of recurrent UTI seems to be successful but urine monitoring per month should be done. I gave her a urine collection bottle and asked her to know volume of water drank per 24 hours. I hope the new apartment will be free of dog urine smells as friends can smell it but owners who live there will not smell it as their noses are used to it.

Will wait and see. The "living happily ever after" story has not concluded but it seems that there is a good clinical outcome of my recommendations and that is what the lady in red wanted and what all owners whose pets have long suffering diseases demanded.

765. Adopt sick or old dogs

Today I had a woman in her late 40s bringing in a 9-year-old male and a very thin 5-year-old pregnant female cocker spaniel for examination as she had adopted them. The dogs needed dental cleaning but she would not want to pay for the services. She went to get something from her van.

Suddenly she rushed back to say that a gasping puppy was present on the floor of her front van seat. I got the puppy which was attached to the placenta out and tried to revive it. Her teenaged daughter was not afraid of the smell and I taught her how to clean the puppy. The dam had little milk and so I asked them to buy milk powder.

Below is another example of adoption of sick dogs

I have an enquiry to make and would really appreciate if you could help. I have decided to adopt a 6 months old Shetland sheepdog and border collie mix, but the breeder told me that he has skin problems, (he thinks it is fungus) on his back. I would like to know if I should wait for the wounds to heal before adopting it or i can adopt it and bring it to the vet for a check. If I were to bring the dog for a check at your veterinary, how much would it cost, ad how long would it take for the skin problem to recover?

Thank you,

I am Dr Sing. It is best to adopt a dog with no skin disease. As for vet costs, it depends on what is the cause of the skin disease and prices vary from $60 to over $200 for complicated skin disease cases.

Thank you for the reply. I have decided to get a healthy 3 months old Sheltie. May I know how much will it cost for the third vaccination and microchip at your veterinary?

Thank you,

New graduates of Murdoch Univ - Dec 2, 2011

On Dec 2, 2011, the 5th year Murdoch Univ vet students were informed of their exam results in a graduation dinner. I had met some of the Singaporeans last year and there was one I was particularly concerned. Did this person pass or not? Has this person wasted 5 years studying a most-sought after profession? I was glad this person had passed and has become a vet.

Apparently, according to this person, in Australia, a new vet earns around A$3,500 per month while a dentist earns A$10,000 a month and a doctor earns A$500/day. I don't know why as vet undergraduates are straight As or are top in their cohort during 'A' levels. In Singapore, a new vet earns around S$3000 - $4,000 a month generally.

Those Singaporeans with rich parents open their own practice after one year of experience as the regulatory authorities permit this. That is why we have around 50 vet clinics in 2011. Flyers are distributed into letterboxes by some of the new practices to announce their presence. This practice had been done by some of the previous vets too. Some did it by proxies using the groomer.

Will a vet earn more when they start their own practices? Maybe in the long term for many of them and if they are much less "expensive" than the older vets. But there are vets who have had closed their practices.

Good communication with the owners is usually lacking, according to this new vet I spoke to yesterday. It is very important in private practice but seldom taught in vet school. Technical skills can be picked up from books. "Doesn't Murdoch Univ teach communications with clients?" I asked. "There is a video presentation of consultation with clients and feedback."

Communications with clients is easily taught. It is part of the personality. Some do it very well. Some can't do it. I said to the new vet: "But at the end of the day, it is still a correct diagnosis." When a diagnosis is correct, the dog gets well and the owner returns or refers.

Academic results at Murdoch Univ batch in 2011
Probably 60 students in the 5th year
9 get high distinctions (HD) (over 80% in Year 3,4 and 5).
1 failed
Distinctions (70% - 79%)
From what I know, two ladies in the HD are from Singapore. One of them got 79.5% and I am glad that she got the award as the professors recognised her hard work and efforts. "What if she got 79.4%?" I wondered.

Being top in academic performance in vet school is great. It can lead to great arrogance that the world is their oyster. To succeed in private practice, academic excellence with arrogance leads to disaster for the practice and possible sacking as clients provide adverse feedback to the principal.

763. Pupillary light refex - A paralysed Shih Tzu

Yesterday, Dec 8, 2011, I was consulted about a Shih Tzu that was "paralysed". The sister had phoned me on Dec 7 for a 3rd opinion and I had asked her to send the dog in for examination as it is difficult to know what is going on by phone diagnosis.

The dog was treated by Dr Vanessa on Dec 7 and so I asked her where was the area of pain. I had seen the dog lying sideways in the crate. My assistant Min said Dr Vanessa had treated the dog. She came in around 11.30 am. I was about to talk to Dr Vanessa when the brother came in. This was the best time as it is always good for the owner to be involved in the examination.

AREA OF SPINAL PAIN
The dog had been treated by Vets 1 and 2 with steroids and so the area of spinal pain was not specifically known to Dr Vanessa when she received the dog. "Which area of the spine is painful?" I asked her since she had given a steroid injection and any pain would be masked.

The dog was able to lift his head but was unable to stand on four legs and that was definitely injury to the central nervous system. "Slight pain is further to the back area," Dr Vanessa said. It would be difficult to diagnose pain in the spinal area when the dog had been treated with pain-killers by Vets 1 and 2. Their medical records were brief. Acupuncture was done by Vet 2. But both of them had not done any X-ray. Later in the evening, the sister who had taken the dog to the vet spoke to me and said that she was given the choice of "X-ray" and/or "MRI."

There seemed to be some miscommunication here. Since I did not speak to Vets 1 and 2, I would presume that they had advised X-ray and the owners had opted out but the owner had said she was not a professional and should not be given a choice. It is extremely difficult nowadays. I usually advise X-ray in such traumatic cases and if the owner declines, I will record it down in my medical record. This is to avoid this type of "mis-communication".

For this report, I would focus on the pupillary light reflex done on the Shih Tzu in the presence of the brother. A bright light was shone directly on each eye to check the consensual and direct pupillary light reflex

DIRECT EYE REFLEX
Left eye - pupil does not constrict
Right eye - pupil constricts
So, what is the problem?

See notes from Wikipedia below.



Clinical significance

In addition to controlling the amount of light that enters the eye, the pupillary light reflex provides a useful diagnostic tool. It allows for testing the integrity of the sensory and motor functions of the eye.[1]

Under normal conditions, the pupils of both eyes respond identically to a light stimulus, regardless of which eye is being stimulated. Light entering one eye produces a constriction of the pupil of that eye, the direct response, as well as a constriction of the pupil of the unstimulated eye, the consensual response. Comparing these two responses in both eyes is helpful in locating a lesion.[1][5]

For example, a direct response in the right pupil without a consensual response in the left pupil suggests a problem with the motor connection to the left pupil (perhaps as a result of damage to the oculomotor nerve or Edinger-Westphal nucleus of the brain stem). Lack of response to light stimulation of the right eye if both eyes respond normally to stimulation of the left eye indicates damage to the sensory input from the right eye (perhaps to the right retina or optic nerve).[1]

Emergency room physicians routinely assess the pupillary reflex because it is useful for gauging brain stem function. Normally, pupils react (i.e. constrict) equally. Lack of the pupillary reflex or an abnormal pupillary reflex can be caused by optic nerve damage, oculomotor nerve damage, brain stem death and depressant drugs, such as barbiturates.

Normally, both pupils should constrict with light shone into either eye alone. On testing each reflex for each eye, several patterns are possible.[6]

Optic nerve damage on one side: (Example in parens.: Left optic nerve lesion)
The ipsilateral direct reflex is lost (Example: when the left eye is stimulated, neither pupil constricts, as no signals reach the brain from the left eye due to its damaged optic nerve)
The ipsilateral consensual reflex is INTACT (because light shone into the right eye can signal to the brain, causing constriction of both pupils via the normal oculomotor nerves)
The contralateral direct reflex is intact (because light shone into the right eye can signal to the brain, causing constriction of both pupils via the normal oculomotor nerves)
The contralateral consensual reflex is lost (because light shone into the eye on the damaged side cannot signal to the brain; therefore, despite the right eye's motor pathway (oculomotor nerve) being intact, no signals from the left eye are able to stimulate it due to the damage to the sensory pathway (optic nerve) of the left eye)

Oculomotor nerve damage on one side: (Example in parens: Left oculomotor lesion)
The ipsilateral direct reflex is lost (Example: when the left eye is stimulated, only the right pupil constricts)
The ipsilateral consensual reflex is lost (Example: when the right eye is stimulated, only the right pupil constricts)
The contralateral direct reflex is intact (because light shone into both eyes can still signal to the brain, and the pupil on the undamaged side will still be able to constrict via its normal oculomotor nerve)
The contralateral consensual reflex is intact (because light shone into the left eye can still signal to the brain via the normal optic nerve, causing attempted constriction of both pupils; the contralateral pupil constricts via its normal oculomotor nerve, but the ipsilateral pupil is unable to constrict due to its damaged oculomotor nerve)

I will write more later

782. The cat with foul-smelling ears claws the owner ferociously

"My cat cannot walk properly, hunching her back and not walking normally with the hind body upright. What is the problem?"

The cat walked with hind limbs low on the floor as if stalking a prey. Hind limb lameness. Why?

As I did a full body check, the cat's ears were strongly smelling of bad rotten flesh. "Did you get the ears treated?" I asked the lady.

"I consulted the vets (at another practice) twice," the woman said to me. "They give me ear drops. The cat scratches me when I tried applying the ear drops. I gave up."

On the surface, it seems that ear infections and lameness are not related. Yet if you think about being a cat. What would you do if you have such painful smelly ears over the last few months? You would try to relieve your itchy ears with your back paws. Both ears. Both paws. You do it so often and over the months. Would you not strain your hind limbs and joints? Ear drops were not applied. You claw your owners for doing it. So, in time, you feel the back pain in trying to relieve your ear itchiness and hurt your back muscles. So you slink when you walk. Can't walk upright. A hypothesis.

That's my theory. "I will sedate the cat after a day of antibiotics and anti-mite injection," I said to the owner. It was a surprise to her that I had proposed this approach as she expected me to prescribe "ear drops".

Today, 2nd day. The ear stench was much reduced. The cat still clawed but much less. The right ear had lots of wax and debris. Will irrigate the ears under anaesthesia and hope that this will help the cat not to sufer any more pain. The last option would be surgery to open up the vertical ear canal. But not now. Wait and see after ear irrigation and painkiller/antibioitc medication which is a simple way.

781. The father's day present

Yesterday, Tuesday, I worked past 7.30 pm and at 5 pm, I met a senior citizen who brought in a gold and white Shih Tzu of around 8 months old, with a bleeding toe nail. Dr Vanessa had treated it and bandaged the left hind foot.

"I better not do it myself next time," the taxi driver told me.
"Why did you buy this gold and white shih Tzu?" I asked.
"My son bought it for me," he said. "A present on Father's Day. From his friend."
I was surprised that the undergraduate with a scholarship would buy such a big responsibility for his father.
It was a good gift since the father loved the dog. "My wife used to dislike dogs," he told me. "But after getting this one, she loves dogs."
"That is great news," I said. "How is his toilet training?"

"I put his urine on the newspapers and he just go to the papers every time he needs to pee and poop," the father held on tightly to this high-maintenance dog.
"This is an intelligent dog," I said. "However, he is very thin. Feel the sharp spines," I showed the father. The thick luxuriant coat had covered up the thinness of the body.
I advised adding dry dog food to the usual canned food, at 80% dry food and the dog would put on weight. The son is good as now his parents have some company in an empty nest. Aged parents become "children" nowadays and so it is good that the dog keeps them company.

780. The 1.5-year-old cat started spraying his urine is under the scalpel today

Wednesday morning.

A mother and her teenaged daughter rushed in with an older male cat for neuter. An "orange" cat that resembled the other one I wrote about last time. The same colour. That one bit the mother's hand while the mother was preventing him from the stray cat.

As time is precious to Singaporeans, I told the mum to go to Toa Payoh Hub with her daughter (school holidays) for one hour and come back instead of going home and come back again. She lived in Simei which is around a 30-minute drive away. "There are other clinics nearby your condo," I said. For some reason, she preferred Toa Payoh Vets and I was quite surprised.

"319074" was the postal code I had given to her when her daughter phoned the Surgery for the "pin number" as her driver mother could not locate my surgery. Nowadays, it is so easy if you have the GPS to locate places.

ANAESTHESIA
Weight: 5 kg
Xylazine 0.15ml + Ketamine 0.6 ml = 0.7 ml IM in one syringe.
Waited 10 minutes. Needed isoflurane gas 5% top up for less than 30 seconds. This shows that the dosage is a bit low for 5-kg cat. Should be xylazine 0.2 ml + Ketamine 0.8 ml without the need of topping up with isoflurane gas.

I ensured that whole scrotal and surrounding area has been plucked clean by Min and showed him how it could be done. Cleaned up scrotal area. Horizontal cut exposed two testicles. Removed them. Washed away the blood. When the owner came 2 hours later, the horizontal would appears to close together, so no bleeding or wound is seen. I asked Nicole to take a video and to record oral instructions of post-neuter care for video production. Hope this will turn out very interesting.

I asked my assistant Nicole to take some pictures to prepare a video on how to care for the cat after neutering. I had a rare case of a male cat's scrotal wound not healing some 14 days after neuter by Vet 1. So, these two cases would be able to illustrate the educational video on "post op care after neutering."

"You need to be a good story teller to connect with the audience viewing your video," I said to Nicole. "A good story is usually one where the viewer wants to know what's happen to the protagonist. For example, the video of FIV in a stray cat done by the two Temasek Polytechnic Vet Tech students. Do you find it engaging?"

"Yes," she said.
"Now, if you produce a video of 100 FIV cats with all their diseases, would that make it an interesting education video on FIV in cats?"
"No," she agreed.
"Similarly for the video on Caesarean sections produced by you for the 'Responsible Pet Ownership' video. There is no connection showing many picures of the dog and puppies after Caesarean section in the video. I would have shown the Maltese about to go under the Caesarean section. What happened to her. Did she give birth or not? Were all puppies alive? What happened next? Instead, several images of other dams and puppies after Caesarean sections were in the video."

I give free rein to the young ones to be hands on in producing the videos and that is how they learn. If I spoon-feed, they learn nothing.

759. Health screening for an 8-year-old Silkie

"You have got your money's worth today," I said to the strict-looking wife as my assistant expressed more than 5 ml of road-tarry grey granular oil from the 8-year-old solid body male neutered Silkie Terrier. "For the past 8 years, no groomer or vet had expressed his anal glands and the normally light yellow oil had turned grey. I am surprised that the dog had not bitten his tail or his backside."

Showing what is wrong is important in vet practice. The woman in her late 30s and her taciturn husband smiled a bit. Humour is sometimes important in connecting with new clients. They were from Woodlands. The wife wanted a health check up from me and had made the appointment the day before. Vet 1 had told her that her dog suffers from Grade 1/2 heart murmurs and so she would want me to give a complete check. "The heart murmurs are confirmed," I said. "But it is not serious since your dog has no coughing or loss of energy." That was good news. "If you want X-ray to see whether the heart is enlarged and the lungs are normal, let me know." The left femoral pulse was of poor quality but I have to check again this Sunday.

"Is it necessary?" she asked.
"No," I said. "It is advised as there are no signs of heart disease.

"There are so many new practices with beautiful furnishings and furniture," I compared my older premises to such new practices and asked where she would come quite far to consult me. Many Singapoean pet owners are impressed by new clinics with their shine. "New furnishings are not important," the wife said to me. "It is the vet's experience."

PHYSICAL EXAM - normal despite complaint of the dog turning his neck to the side sometimes. A painful throat but the dog disallowed mouth opening. He would twist and turn whenever I tried to pry open his mouth. "I will check for infection or tumours of the tonsils and the back of the throat during dental next week," I recorded this finding.

BLOOD TEST - ALT increase double the higher range. Liver or muscle damage but this will need another test.

URINE TEST - "Not a chance that my dog had peed this morning," the wife said to me. "We watched him closely and brought him straight to you from Woodlands." Yet when I passed a urinary cathether into the small bladder, I could get around 10 ml of urine. Why?

Results - Bacteria 3+, protein trace, bilirubin +, SG high, pH 6.5, casts but no urinary crystals. Only the bacteria count was considered significant.

"Your dog may have cystitis - a bladder infection," I said to the wife by phone. The dog was neutered very young at 8 months and his belly and neck were pigmented due to scratching. As to the cause of this black skin pigmentation, it is hard to say but it resulted from skin scratching over a long time of years.

"Does he need antibiotics?" she asked.
"I did give you some baytril tablets 2 days ago for dental scaling, to kill off bacteria in the mouth 7 days before dental scaling," I said.

"Is my dog fit for anaesthesia since he has liver disorder?" she asked.
"The ALT enzymes are not very high and the dog has good appetite. He should be OK for anaesthesia this Sunday."

Today is Wednesday. I will do the dental scaling this Sunday. Overall, the dog has passed his health screening.

758. A dog owner asked about post-op spay care from Dr Sing

Pre-Operation Guidelines for Spaying your Dog.

. The best time to spay your female dog is 2 months after her heat and at an age over 6 months

• Schedule an appointment with your vet. A blood test to screen your dog's health is advised one day before surgery.
• Make sure your dog is healthy, eating & drinking well for the past 3 days before surgery
• Give your dog a good bath, and wash the surgery area well the day before surgery

• Your dog should not eat or drink after 10pm the day before surgery, or 12 hours before surgery to prevent vomiting and choking during anaesthesia
• Bring your dog to the vet in the morning so that you can collect it in the evening after the day surgery.

Operation Procedure

• Your dog will be weighed and examined before surgery.
Isoflurane gas anaesthesia and/or an injectable anaesthesia will be given according to your dog’s health and temperament.
• The spay operation take about 30 minutes if there are no complications like bleeding


Post-Operation Guidelines for Spaying you Dog.

Frequently Asked Questions

1. What kind of food do I give, and when can I start feeding her?
If you take your dog home on the evening of the operation, it’s best to feed your dog the next day as there will be a possibility of vomiting due to the anaesthesia.

2. When can I bathe her?
Wait at least three days before bathing your dog. Cover up the wound with a water-proof plaster before bathing.

3. When do we remove the stitches?
Some vets use dissolvable stitches which will dissolve on its own, however, the vet may instruct you to return after 14 days to remove any remaining stitches.

4. What do I do in an emergency, or if the stitches break down?
If there is minor bleeding after a stitch tears apart, bandage the wound and bring your dog back to the vet as soon as you can. In case of emergency when the intestines can be seen or there is heavy bleeding, call your vet immediately.

5. When can I take off the Elizabeth Collar?
The E-Collar must be worn for 24 hours for 10-14 days, or until the stitches are completely removed.

6. Change the plaster protecting the wound on Day 2 if the vet has used a plaster.

7. Give pain relief and other medication as advised.

4-month-old red poodle scratches his ears vigorously

Today, Tue Dec 6, 2011, I was surprised to see a trim couple in their late 20s all the way from Sengkang wanting to vaccinate their puppy (3rd vaccination). The puppy was bought from a groomer in Pasir Ris with scales like dandruff in the legs and ears and ear edges.

"My puppy keeps scratching her ears vigorously," the wife said. The edges of both ears had fine scales. The ear pinnae, the four legs also had lots of scales. What's the cause?

SKIN SCRAPINGS 3 AREAS
I suspect scabies. I used a new scalpel blade and scrape the skin of ear edges and the paw. No ringworm. No mites seen under the microscope.
"No mites can be seen as it is possible that the experienced groomer-breeder has had treated this puppy," I said. "The mites are deep under the skin and that is why they are so irritating as they tunnel under the skin and breed."

No proof of mites but I could demonstrate the ear scratch reflex. I rubbed the edge of the right ear and the right hind limb starts to wriggle and ready to scratch the flank and chest.

GRATE + PEN TRAINING.
The puppy was paper-trained in a confined area for the first 5 days but started accidents as the wife decided to widen the space for the puppy. "It should take 14 days of close confinement to succeed in paper training," I said. "The puppy can go inside the crate (grate+pee pan) as a toilet or living den. However, the couple bought a grate + pee pan. It worked. So good.

756. Adopting dog with skin disease - vet cost

755. Sunday's interesting cases. The male cat bit the mother is neutered

Sunday's interesting cases of two male cats that got neutered

CAT NEUTER NO. 1
I was on duty in the morning of Dec 4, 2011. Bright sunshine although showers come in the afternoon. My first case was a Malay family bringing in a muscular male yellow cat with brown dots of 10 months for neuter. "I phoned yesterday for appointment at 10 am," she said. "This cat bit my mother and so I want him neutered!"

"Cats in Singapore apartments don't bite people, unlike dogs," I said. "Why would he bite your mother?"

"He was chasing away a stray cat that came to our apartment door," the lady said. "My mother grabbed him to stop him. He bit my mother's hand!"

Never interfere in fighting cats or dogs - that is the morale of the story.

NEUTER
5.5 kg. My formula is xylazine 0.1 ml + ketamine 0.4 ml IM for cats <4 kg for a female cat spay. In this male cat, the above dosage was given. It was effective even after a delay of 15 minutes as I had to vaccinate the Chihuahua who had bitten me when I visited the apartment some years ago. He was neutered and adopted by Theresa and daughter, a Myanmar family in Toa Payoh, that loves him very much. This dog was given up by another family in Mandarin Gardens as he was a handful, peeing and pooping everywhere. "Does he pee all over the apartment?" I asked. "No," the mother and daughter said. "He just goes to the toilet." This was a good ending for this naughty male dog who had put on considerable weight. As I had injected the above-mentioned cat, I informed Theresa that I had to rush and it was OK with her as she had to go to the market. She had started her employment agency business. "How's your business?" I asked her. "Not good," she said. "The MOM (Ministry of Manpower) keeps rejecting every application nowadays." There is a political shift of not granting work visas for foreigners as liberally as before since the locals are not too happy as these foreigners affected their salaries. CAT NEUTER NO. 2
A woman with a son with dark blue pierced ear studs on his left ear came with 2 cats that had been neutered and spayed 9 days ago by Vet 1. "The female cat is OK," I said. "The stitches will dissolve soon. There is one small hole due to stitch coming out but it is not a problem." She asked: "Can I bathe her? She is so smelly!". "Yes," I said. "Just put a plaster onto the wound and bathe her."

As for the male cat, there was an open hole in the right scrotal area with reddish discharge coming out. "This is very rare," I said. "I have not encountered such a case in my more than 30 years of practice." Vet surgery is always full of surprises. I said: "It could be something stuck inside the wound and that is why it is not closing. There is no pain at all when I press it. Still the cat must be sedated and the open wound examined."

"I have asked my friends and they say that cat neuter wounds usually close within a few days."

All surgeries do give rise to complications of one kind or another in some cases for all vets including some of my cases. Like infection, bleeding, pain. In this case, there was yellowish nodules coming out as I pressed the 5 mm vertical hole in the right scrotal area.

I gave the cat a very low dosage of xylazine 0.05 ml + ketamine 0.2 ml combined IM and collaborated with
Dr Vanessa to handle this case as part of my coaching program. "Put the artery forcep into the gap at 12, 3, 6 and 9 o'clock and pull out any strands of tissues." Systematically. She flushed with normal saline. I wanted the cat to go home as the owner mentioned about loose stools in both cases, since the two cats was given Clavulox for the past 9 days and I am worried that the cat would develop full diarrhoea in the Surgery. But Dr Vanessa advised keeping the cat in for observation and I was OK with it. From my experience, this wound would close after removal of debris inside. But it is wise to listen to other vets.

I phoned the owner who was at the back coffee-shop that the male cat remained in for observation. "This is my first cat," she said. "It is like first love," I said. "It is always remembered. Usually it is puppy love as we usually don't marry our first love! Have you got a first love, young man?"

The pre-teen boy who love jazz music seemed to nod his head. "But mum, you are a doggy person," the pre-teen son said to the hard-working mum who had much conferences to organise. I had more time to talk to them as Dr Vanessa handle the majority of Sunday's cases after 12 noon. It was good to see mother and the music son being close.

EYE ULCER IN THE SHIH TZU AGAIN
"The previous Shih Tzu had no eye problem," the lady in her late 30s brought back a young Shih Tzu with the right eye white red and tearing. The left eye had a central white scar but the eye white was not reddish.

I had not seen the other Shih Tzu but from what I had seen from other owners, the Shih Tzu could have less protruding eyeballs and its corneas would be pigmented and black due to irritation over time. "It is hard to say that your old Shih Tzu had no problem," I said. "Many Singapore Shih Tzu owners, in the old days, just ignored the eye problems as the Shih Tzu scratches to relieve its eye itch and pain. I would expect your Shih Tzu to have black or brown corneas unless its eyeballs were less protruding."

"You did stitch up the eyelids of both eyes some weeks ago," the lady told me. "Yes," I referred to my medical record where I illustrated two eyes. The left eye had a central ulcer which is now healed white spot of 3 mm with some blood vessels. The right eye cornea was written as "cloudy," but not ulcerated and would have healed.

Dr Vanessa put in the fluorescein strip and flushed off the green dye with a syringe of saline. There were 3 corneal opacities seen. At 3 o'clock, central and 9 o'clock but they were not stained green at all after flushing off the green dye by Dr Vanessa. "It is surprising," I said. "These ulcers are over 3 mm in diameter and yet they don't stain green as expected." The dog had been rubbing his right eye despite an e-collar of size 12. I recommended size 15 and eyelid stitching up again for 14 days. The owner wanted the dog home on the same day although I advised retaining him for a day or two.

"The solution to this case is to get the facial fold cut off by the vet," I advised. I took out the Canine Opthalmology book and showed her the operation and the illustratons in this old book.

"Your dog goes to the groomer regularly to get the fold hairs snipped but the hairs grow fast and irritate the cornea causing ulcerations. You also snip the hairs but it is not easy to do it frequently. The hair grows and the water and liquid is trapped in between the facial fold and the lower eyelid leading to itchiness."

The owner was not in favour of surgical resection of the facial fold as it cost money. It is important that the vet informs the owner of a long-term solution to the problem for Shih Tzus and Pekineses as many owners are not aware of such a solution.

755. Ten ivermectin injections for a hamster with skin disease

Many lady hamster owners in Singapore are sophisticated and well educated. A lady asked if I had ivermectin for her hamster who has hair loss on the back and has been "cured" by Vet 1 near her residence with injections. Ten injections over the past few months but the problem came back. I had just performed a haemangiosarcoma surgery on her old white dwarf hamster which did not survive the surgery. The tumours were large and the cells were breaking down. Full of blood. The spinal area was invaded by the tumours. The dwarf hamster could not survive the surgery. The lady was understanding as I showed her the tumour cells and pieces taken out.

"It is ivermectin," she had the info from Vet 1. "A small drop". I don't give ivermectin by 10 injections to dwarf hamsters as I believe it is harmful as hamsters are so small. She said she would revert to her vet and asked for her hamster to be cremated.

754. SOP - Old cocker spaniel with skin disease

Cocker Spaniel. Head wounds, whole body skin infected. Saw the vet many times. Recovered, then skin disease again. Now over 12 years old. Eye pus.

SOP
1. History. Ear canals full of pus.
2. Blood test - Total WBC high.
3. Skin checked for ringworm, mites
4. Advise ear canal surgery when the dog has recovered. But the owner usually forgets about it.

In this case, I told the owner that the originating problem was the chronic ear infections and that an ear surgery when the dog was young would have resolved much of the scratching of the neck and flanks. Floppy ears. Covered up ear canal. No ventilation. Dampness. Bacterial growth. Pus form. Ulcers inside ear canal. Very painful. Head shaking. Hind leg scratching. But no hope from medication and groomer as problem recurs.

It is hard to persuade the Singapore Cocker Spaniel owner to do ear surgery.

753. SOP - Gangrene in an old dog's tail

The dog cut his tail spirally with a wound of 10 cm long. There was a lot of bleeding. Vet 1 stitched up and the dog went home after 4 days of being warded and cared for at Toa Payoh Vets. Gangrene developed lower down the tail. The dog had fever. The owner phoned me. What to do?



1. General examination
2. Complete blood test
3. At least 2 days of antibiotics and NSAID
4. Observe dog's appetite
5. Blood test before surgery is advised to check total WBC.
6. Isoflurane gas + O2 only at 1-2% intubated. IV drip.
7. Use electro-surgery
8. Amputate higher up to avoid gangrenous toxic tissues.
9. Post-op to stay in Toa Payoh Vets unless the owner insists on going home.

TIP. Many Singaporean dog owners have no time or are bitten when they try to clean the wound post-stitching. The e-collar worn did not prevent the dog from traumatising the tail due to pain. A long black area of the tail of more than 10 cm long developed. Gangrene. Dog had high total WBC when I admitted it. Best advice is to amputate the tail at the first instance as the owners just can't manage to nurse. Pain-killers with NSAID are not very effective in tail wound injuries for some reasons. So, I do advise tail amputation and have never received any unhappiness. In private practice, a good clinical outcome is what the owner wants. No repeat visits as this means spending more money at the vet.

752. SOP for hind lameness for an adult dog

Yesterday, Dec 1, 2011 at 7 pm, a lady in her late 20s came with a 13-year-old Jack Russell. "He is better today," she said to me as I was at the reception counter. I could see the unique make up of a certain airline cabin crew and enquired whether she was from the airline. I said: "Hair in a bun and clipped, as slim as can be, a gait with confidence and a type of facial make up that never fails to attract attention."

"It is called ghost make-up," she was surprised that I could guess correctly her profession. Well, I do to see these slim and pale-looking ladies with blue eye shadows at the Singapore Changi Airport going to work or coming home. I did not realise that they look like "ghosts" until she told me.

In the consultation room, I did the examination with Dr Vanessa. A right hind lameness was the presenting sign. The dog's right paw was barely touching the floor. "This lameness has been going on for many years," she said. Other vets had examined it. I asked Dr Vanessa to do first and then I demonstrated my approach.

The Standard Operating Procedure.
1. History of lameness & general examination including teeth.
2. Observation of gait on the floor
3. Put the dog on the examination table. Muzzle the dog.
4. Palpation of spinal column. No pain/painful? Where?
5. Manipulations - dog standing (extend both hind legs and compare the length*). Put dog on side (left, right, upside down).

This is where I have to demonstrate. Basically, it is palpation, extension, flexion, abduction and adduction. Check patellar luxation.

*Put thumb on hip joint, extend hip, and knee of both limb while the dog stands on front legs. Show the owner the unequal length of the hind limb (if there is subluxation).

6. X-rays (2 views) if necessary. Arthritis, Legg-Perthe Disease, Subluxation, luxation of the right hind compared to the left hind hip.

7. Complete blood test to check for liver or kidney disease is recommended as lameness in 13-year-old Jack Russells may be caused by other reasons.

8. Costs to be made known to the owner.

750. SOP - Post-purchase exam of a mini-Maltese

Yesterday, Dec 1, 2011, a mother and young daughter came specifically to see me with a newly purchased mini-Maltese. She was given 24 hours for vet examination of this Maltese which cost $1,500.

I did the case with Dr Vanessa as I want to standardise the procedures in the post-purchase examination at Toa Payoh Vets to ensure a high standard of care and medical recording. Basically to be able to defend the practice in the event of litigation and complaint investigation.

As in the medical profession, each doctor has his or her own approach to post-purchase exam of a puppy. I want to make sure that Toa Payoh Vets' approach cover the bases and be able to be defended in the event of litigation and this is where I have to implement the Standard Operating Procedures (SOP). In equine medicine pre-purchase examination, the SOP is quite well defined but I don't find them commonly available in canine medicine.

The SOP is as follows:

1. Use the General Examination form and fill up the details of examination of the major body systems. Dates of the 3 vaccinations to be recorded. The vet is to be meticulous in doing the examination and recording all questions asked in the form and write remarks/comments. He or she is to sign and date the form. One copy for the owner and one copy to be kept at Toa Payoh Vets in the medical case file.

2. Do a Parvoviral test. This is mandatory for Toa Payoh Vets as parvoviral infections are common in breeders and pet shops.

3. Other tests are optional and must be explained to the owner. This includes complete blood tests, urine test, faecal test, ultrasound and X-rays whenever necessary.

4. Record house-training technique of new puppy - paper-training or grate training. The vet is to advise if he or she is able to do so. Most first-time owners appreciate this advice but not all vets can advise as it is a more complicated subject and needs reading up first.

5. Inform the owner that the Seller may have given medication to the puppy to suppress coughing (Kennel cough) and it will take at least 7 days to know if the puppy has viral and bacterial infections acquired at the Seller's premises.

749. Cataract surgery in undeveloped countries

This is the operation performed by Dr Sanduk Ruit.

Can this be done on dogs as presently it costs over S$3000 to do a cataract removal in an aged dog in Singapore?

748. Verrucca

There was a suspicious growing brown growth on my left chest. It was around 0.5 x0.5 cm x 0.2cm. As I do advise pet owners to get growths removed when they are small, esp. for older pets, I practise what I preach. So, today, Monday, Nov 28, 2011, at 7.15 am, I was at the Ambulatory Surgical Centre of the Singapore General Hospital to remove "verrucca" as stated by my surgeon. Last week, I saw a nurse from China googling when I was sent to the room to receive financial conselling. This is compulsory for all. "What are you googling?" I asked the friendly nurse who had seen me before for a synovial cyst excision on my right thumb. "Just to check the spelling of verrucca what Dr Foo wrote," she said. I was impressed with the thirst for knowledge imparted to the nurses.

On the surgical table, I asked Dr Foo whether he could remove the many red growths, as if blood vessels had burst. One young nurse told me: "In China, your many red spots on the man's skin are signs of good fortune." No wonder I am still alive.

I had a blood pressure monitoring arm band on my left forearm which expanded at regular intervals, giving readings in red.Another nurse who monitored my blood pressure asked if I have been active exercising. "Low pulse rate? Is it good or bad?" I asked the nurse. Low heart rate seems to be uncommon for senior citizens as I had been asked this question in another surgery. "I don't think Dr Sing exercises at all," Dr Foo commented correctly.

The carbon dioxide laser machine came into the room. I had multiple warts on my upper chest and so this machine would be useful. The nurse swabbed my upper chest with some liquid. Then Dr Foo got a purple marker pen to circle the verrucca or warts. "How many warts do you mark?" I asked Dr Foo. "Eleven. I am injecting local anaesthetic," he said. "It may be painful."

My eyes were covered by a piece of wet swab to prevent the bright operating lights blinding me. So I could not see what was going on as the laser buzzed. I could feel slight pain in some and none in other wart removal areas. A whiff of BBQ smoke pased my nostril. Soon, it was over. 3 samples of growths were taken for histopathology. The red one which was said to be a haemangioma and would recur when removed. A brown wart. Dr Foo said to the two young cheerful nurses from China: "Take the one rounded brown growth Dr Sing was worried about for the lab." I thanked him. "It could be an accessory nipple," he said of the brown growth near my armpit. "It is on the line," Dogs do have 5 pairs of nipples and well I knew what he was talking about.

Overall, it was a pleasant and enjoyable experience at the operating theatre. The bright yellow Crocs clogs were outstanding in two nurses. The others wore blue, green and black coloured ones. One man wore white boots. The cream0white vinyl tiled floor with red square patterns was very clean and shiny. There were 6 operating theatres. I could not understand why the large word "WASH" was pasted on the stainless steel sink where the surgeons scrubbed up and washed their hands pre-surgery. I saw one surgeon putting on a cloth glove and two more pairs of latex surgical gloves. "Some surgeons are allergic," the kind nurse explained to me.

747. The tu tu kueh woman's dog

Yesterday was a long day at work on a Sunday. I usually work half a day and let Dr Vanessa do the rest. I asked Mr Min to take the afternoon off and so I stayed around and stayed to do some administration. A practice needs to be administered well or it will just suffocate and wither as the world is getting complex and competitive. The clients are getting sophisticated and more demanding.

For example, one client wanted me to excise a large paw haematoma without sedatives as she was afraid that her old pug would die under sedation. That is a valid fear. To do it or not? It is up to the vet. The vet can just reject her case. What if the old pug dies under sedation? And nobody can predict this. For the sake of the old pug, I incised the haematoma and let it was OK.

The tu tu kueh woman at Bishan Shopping Mall. She asked what stall I was managing as she had seen me so many times over the years buying tu tu kueh from her and asking about her work. She had cooked soup which was shared with other woman stall holders and her brother who sold cakes under the same boss. When I told her I am a vet, she said: "I cried a long time when my dog died. Just running nose. A lot of it. My friend sent it to a vet. Some injection. Hospitalised for 2 days. My dog died. Just runny nose. Goes to the vet. Injection. Died."

"There could be many reasons," I said. "It could be a drug allergy. It could be a serious infection. How old and what breed?"

"7 years old. A Pomeranian." Her eyes teared up as she remembered her dog so well.

Now this dog was a clever dog. "My dog would jump and greet me when I unlock the apartment door. He could hear my key sound. When other family members unlock the door, my door would ignore them," she said, turning her head sideways.

"When I stayed too late watching TV, my dog would lick my ears to ask me to sleep. If I did not, he would jump to obstruct the TV screen."

"That sounds like a very intelligent dog," I was surprised. "It is as if he was a very caring human being re-incarnated as a dog." Some religions believe in re-incarnation and this canine story seems to support this.

If I can find a small breed to be rehomed, I will get one for her as she cares so much for dogs.

Sunday's interesting cases - Nov 27, 2011

1. Septicaemia from gangrenous vaginal hyperplasia and prolapse
The Chihuahua passed away after heavy panting. I had a complete blood test done 2 days ago and had informed the owners that the dog had toxic blood. The total white cell count was twice as high as the higher range, the red cells were twice as low as the lower range and the platelet count was very low at 14. Urine analysis showed bacteria and blood (estrus). I noted that her tongue was purplish and that was not a good sign as it indicated some abnormality of health. The blood test was indicative of a septicaemia.

"After two days, the tip of the vagina prolapse became black," the caregiver mum told me over the phone. That was when she consulted Vet 1. The dog stopped eating and was treated but the blackness at the tip spread more. If this was a gangrenous tail tip, it could be amputated. But this was part of the vaginal mucosa. In any case, anaesthesia and surgery of a dog that is not eating and has a lower than normal rectal temperature (37.6 in the first 2 days) was highly risky. The dog was spayed and survived the operation for 4 days. The Chihuahua was 10 years old and was in good bodily condition.

It is important that a blood test is taken when necessary two days after the surgery as septicaemia is an on-going process. The earlier blood test did not show serious changes. In the event of a bad outcome, the owner and all family members will like answers as to the cause of death. Evidence-based medicine using blood test provided the answer.

2. The dog with a gangrenous tail. "It is important that the owners, you and I meet together in the consultation room to discuss about her case," I said to Dr Vanessa who had stitched up a serious profuse bleeding tail wound and had sent the dog home with an e-collar and medication 3 days after surgery. "I had spoken to the owner," Dr Vanessa said. However, I had promised the owner to have a joint meeting as it is hard for me to listen to one side of the story - her side and Dr Vanessa's side and advise. "This joint meeting in my presence is important to clear any misunderstanding," I said to Dr Vanessa. "The owners have not been happy with the dog developing a tail gangrene after surgery. This meeting is not to find blame on the vet. Such misunderstandings from the owners do happen to all vets after surgery, including myself. It is best to meet jointly and clear up all emotional unhappiness."

"I don't blame Dr Vanessa," the owner said first.

"From my experience with tail wound cases, it is usually the dog that traumatises the wound, causing it to become infected and gangrenous. That is why I normally advise tail amputation in serious wound cases as the owner does not know how to take care of it after surgery. However, some owners don't like this idea and want the tail to be saved. In your dog, the tail would be hammered by the end of the e-collar to relieve its pain and itchiness."

"The dog bites me when I try to clean the tail," the lady owner said. "Yet at Toa Payoh Vets, the dog lets the vet change bandage without biting! He uses the e-collar to scratch the tail. The wound opens up. Yellow pus is seen. I phoned Dr Vanessa but she did not answer the call. That is why I phoned you."

"I got a phone call after midnight," Dr Vanessa said.
"Was the tail gangrenous when the dog went home 3 days after surgery?" I asked.
"No," the owner said.

"Many times, the unhappiness is due to financial reasons," I shared my experiences with Dr Vanessa. "You attempted to save the severely lacerated tail by stitching and controlling the bleeding. You sent the dog home 3 days after surgery but the dog can't stand the pain and itch despite your NSAID medication. So, he bites the owner trying to change the bandage. The tail gets infected and gangrenous. Now the owner has to spend more money to get the tail amputated.

"That is why I always advise tail amputation of a seriously wounded tail as the first choice. If the owner declined and the tail becomes gangrenous, there is no unhappiness. You had done on in a cat some time ago when the owner accepted my advice. Have you seen any return of the owner?"

"No," Dr Vanessa said.
"As a vet, we try to salvage the tail. As the vast majority of owners cannot do post-op nursing, the tail becomes gangrenous and this is stressful and expensive for the owner.
