Project 2010-0129
Silkie Terrier, F, spayed, 13 yearsFed dry food + bread since 5 years of age (adopted from another owner who migrated).

2 days ago, presented with vomiting and diarrhoea. I treated and advised blood tests and X-rays if the symptoms persisted. The dog came back yesterday, "dying" according to Dr Daniel who got the X-rays and blood tests done.
A rare case of kidney stones in the 2 kidneys was diagnosed based on evidence. Dogs usually suffer from bladder stones. No urine tests done in this case. 

Blood urea and creatinine are extremely high. The dog vomits dark brown fluid in the crate and has heavy abdominal breathing as at 11.14 am Nov 13, 2013 when the lady owner came to visit as I phoned her to say that the dog was suffering in pain and was on the last leg of his life. The dog vomited white froth on the reception room floor.

The owner will bring home for today and had decided on euthanasia later in the day.
 
Two kidneys are packed with stones
Vomiting and diarrhoea can be a sign of kidney failure although most cases are due to gastroenteritis. This dog was treated for gastroenteritis at the first consultation without blood test so as to reduce medical costs. As the vomiting persisted, I advised a blood test and Dr Daniel took it since I was out. This was a case of renal urolithiasis resulting in kidney failure.

1260. Video: A blood-shot eyed rabbit. Practising evidence-based medicine

PRACTISING EVIDENCE-BASED MEDICINE IN A RABBIT


The young rabbit's eye conjunctiva is dark red and swollen. Tears stream down the eye. In my experience, the grossly enlarged upper conjunctiva is cause by vigorous eye rubbing by the rabbit to relieve the pain and irritation. Something had fallen onto the cornea but on superficial examination, there seems to be no eye ulcer or abrasion caused by this foreign object.

The fluorescein eye stain test showed corneal ulcerations to be green. Almost 3/4 of the cornea is green with only the right sided cornea at 2-4 o'clock being clear.

Unfortunately Intern Clara edited and showed a very short clip of less than 2 seconds. She ought to show much more as this will illustrate clearly the evidence. The theme of this video is using evidence to aid in the diagnosis and the Intern must be aware of the theme and whenever possible, expands on this theme.









The raw footage of the green cornea clips is at another video. Goto:

1259. Videos: SOP for pregnant cat.


PREGNANT CAT SPAYED STANDARD OPERATING PROCEDURES (SOP)

http://youtu.be/E14zwal_yo4

Extra care is needed in operating a heavily pregnant cat. The ovarian and uterine blood vessels are much enlarged and if not properly ligated, there will be lots of bleeding in the surgical area and a possible bleeding to death post-op. A pre-op examination to ensure that the heavily pregnant cat is fit for surgery should be part of the SOP. This was done by me (Dr Sing Kong Yuen). Blood test was not taken owing to financial considerations. The dilemma is whether the heavily pregnant cat should be spayed or should she give birth first. it is extremely difficult to find new homes for the kittens and so spaying was the decision of the owner. The other concern of the owner was whether to starve the cat for 24 hours before surgery.

The cat had eaten 6 hours ago but there is no vomiting with the xylazine + ketamine IM sedation in my experience. No vomiting was present in this case. 

I advise the use of the 3-forceps method to clamp and ligate the uterine body with its engorged uterine blood vessels. The lowest 3rd forceps is clamped and then released, showing a grooved line caused by clamping. Ligate this groove and the ligature will not slip off as compared to ligation of the non-grooved smooth uterine body area. In this way, there is a guarantee of no haemorrhage. The uterine body is then incised between forceps 1 and 2, leaving a good area for the ligated stump to be released into the body.

This spay was done by Dr Daniel Sing using absorbable sutures.  Xyalzine 0.15 ml + ketamine 0.6 ml combined IM was given in this 3.6 kg cat. Isoflurane + oxygen gas top up was needed. There was no bleeding in this spay as the ligatures were properly placed and tight.  The cat was operated in the afternoon and went home in the evening.

A handing over inspection with the owner should be part of the SOP so that the owner can see that the skin stitches are properly tied. At that time, post-op instructions are given preferably by the vet to build good client relationships. Follow up 2 days later is advised by me but most vets do not bother. As at 7 days post-op, the cat is normal and the stitches should be taken out 14 days after surgery although they are absorbable monosyn.

Standard operating procedures are in place to maintain the highest standard of surgery. Handing over inspection of the surgical site with the owner is shown. The cat is OK as at 7 days post-op.

This video was filmed and edited by Intern Clara Chua as part of her experiential learning at Toa Payoh Vets. Interns learn more by writing and making videos than by being an observer looking at the vet's working.

It appears to me to be well edited and has good music. My grateful thanks to Clara. I purchased the Corel software recently as the free Windows Movie Maker does not have many features.

1258. Follow through with rabbit owner on Day 3 by telephone


Dec 10, 2013
Rabbit, born Oct 22, 2013. , Male 1.5 months.

Right eye tearing and red upper conjunctiva - like intense eye rubbing had been done after some objects irritated the eye.

Video shows clearly the condition. 

Many vets do follow up but some don't bother to do so. Maybe the vet school has not emphasized this aspect as follow ups build good vet-client relationship. 

Dec 12, 2013 - Day 3 after consultation
By following up, the vet knows how effective his medication and injections are. In this case, I phoned the father and he went to check personally. He thought the upper conjuncitval swelling (blood-shot) was back to normal but soon phoned to say there was some redness. I asked him to email the images to me rather than WhatsApp.

E-collar not worn.
White stools yesterday but now brown stools as normal
Rabbit is active and eating all the past 3 days.




Owner had changed sharp bedding and ensure hay not sharp. I don't follow up all cases myself as some days are just too busy. But important cases ought to be followed through..

1256, Saving a damsel in distress



Dec 10, 2013

"Many interesting case studies can be broken down into problems and solutions," I said to Intern Clara who had heard all the grass root stories of the Little India riots from my client who came to buy a bag of h/d for his wife's heart disease dog. She had writer's block in writing a good narrative for the Wired Haired Fox Terrier with a lame right fore limb.

"For example, what caused the Little India riots yesterday which was a Sunday? According to the client, it is the driver who drove over the worker and had not shown any concern."

"What's the solution?"
"The authorities want to ban the use of alcohol sales in Little India but he said that these could be purchased elsewhere to consume in Little India.  His solution is for the control of traffic entering this congested road. My solution is to close the road to traffic. He proposed closing to traffic on Sundays."



However, the memorable event was that this gentleman's wife was a 15-year-old young lady in distress some 10 years ago. "She remembered you for helping her Maltese who could not give birth," the gentleman said. "She was lost as she did not know what to do. You did a Caesarean section and saved her puppy."

"Yes, yes, I remember her," I replied. "Her Maltese had difficulty giving birth. She had a big pup. What's happened to the pup?"


"She gave it away. A very intelligent brown and white puppy. She was too young to take care of a puppy at 15 years of age!"

I saw the wife earlier when her other dog came for treatment, but she did not mention about this episode.

I could not recognise her now since she is an adult. 

Many of my old clients have disappeared as there are around 60 vet clinics and proximity will be important to most of them. This couple lived quite far from Toa Payoh and usually I don't have any clientele from that area.

Besides proximity, new attractive expensive renovations of a vet clinic attract the average Singaporean pet owner and Toa Payoh Vets cannot keep up with the new. There will be wear and tear and this clinic, being in existence for over 30 years does not look spring fresh as Spring time despite two renovations.

So I was very happy to have met her earlier after a separation of over 12 years or more and to know she is quite successful in her career, being seconded to freezing winter of 5 deg C in Germany for training now.

1253. Why does the British Shorthair vomits and lose weight over the past 3 months?

A 5-year-old British shorthair vomits now and then for the past 3 months, losing weight. What's the cause? Evidence-based medicine using blood tests need to be practised, but sometimes the owner will not consent to blood tests owing to financial considerations or the misperception that it is not necessary. Vet 1 was consulted and had advised blood tests.




The owner came to me for a second opinion as the cat still vomits, before and after eating. In this case, he agreed to having blood test done. The test showed a high total white cell count indicating a bacterial infection of the blood. After a course of antibiotics and follow up, the cat does not vomit and is gaining weight.

This is an interesting case as vomiting is usually associated with hair balls in the cat. However hair ball vomiting does not lead to weight loss and this cat was thin. So the young couple was concerned.
It could be due to cat food allergies or kidney disease too. However, the blood test indicated a bacteraemia and eliminating this blood bacterial infection results in a happy outcome.

The Singapore pet owner is much more sophisticated than in earlier years. Some are interested in a doctor's youthfulness and energy. Others want an oldie with experience. Some prefer eye candy with good bedside manners. Yet another will check on the good house-keeping of the receptionist area and beautiful renovations of a modern clinic. For others, under-pricing influences his or her decision to retain the services of the vet! Underpricing deprives the clinic of funds for renovations and upgrading and payment of the high escalating operating costs. It is a tough new world for vets in developed countries nowadays.

I had written a report on the treatment of this interesting feline case in my blog or at www.toapayohvets.com
