Electro-excision of a large tumour in a dwarf hamster  Dr Sing Kong Yuen, BVMS (Glasgow), MRCVS Date:   18 January, 2013	toapayohvets.com  Be Kind To Pets Veterinary Education Project 2010-0129
Yesterday, Jan 16, 2013, two older women from "Street 12" came with a 64-g female dwarf hamster aged 1 year and 6 months. She had a gigantic tumour near her left hip. "She's biting the lump", one woman said to me. There was a scab of 2 mm x 2 mm due to the hamster's bite. ANAESTHESIA & SURGERY Dr Daniel is convinced that electro-surgery is useful and efficient as he used electro-excision to incise the skin (see video  http://www.youtube.com/watch?v=J6d03LrHZS8). He excised the tumour which had some abscesses. I weighed the hamster after surgery. She was 50 kg. A heavy weight had been taken out. It was a high risk anaesthesia as the hamster was quite plump and the tumour was massive. However the hamster was still eating. 3 drops of Zoletil 50 was insufficient. "Don't use a large volume of normal saline to top up the syringe," I said to Dr Daniel. "The back muscles of the dwarf hamster is very little. It will be like the doctor injecting 20 ml of liquid into you back muscles. I usually top up the 3 drops of Zoletil up to 0.05 ml in the 1-ml syringe with normal saline before injecting the back muscles of the hamster (see video http://www.youtube.com/watch?v=J6d03LrHZS8). I had to use the mask to gas the hamster with isoflurane gas a few times as the Zoletil 50 was insufficient in this plump hamster. Possibly 4 drops would be more effective in a 64-gram hamster or it could be too much and causes death. Much depends on the vet's judgment and experience. The tumour was 14 g in weight! This is where the risks of death increase because it is not possible to monitor the hamster's breathing and heart rate (ECG, blood pressure monitoring are not practical in a dwarf hamster). Any overdose of the isoflurane gas meant instant death. No such thing as resuscitation. So, I monitored the anaesthesia top up while Dr Daniel operated. It was touch and go. I had to make sure that the hamster was just below the surgical anaesthesia stage and so you would see some leg movement during stitching. It is NOT possible to achieve the ideal surgical anaesthetic stage as in the dog and cat. The dwarf hamster is so small. "Surgery must be speedy," I said to Dr Daniel. "Undermine the skin, isolate the tumour, clamp the base with a curved forceps, excise the lump and stitch the skin with 6/0 interrupted sutures. All these to be done in less than 3 minutes."  The slower the vet operated, the more the anaesthesia had to be given and this is where the hamster "dies" on the operating table.   CHECKING THE ACCURACY OF OWNER'S ADDRESS The had written "Street 12" in the address. I asked whether she had left out "Bishan Street 12"? Vets must check the records of addresses. She said "Pasir Ris Street 12". I asked an intern to do this case study. She did a video and the link is:     http://www.youtube.com/watch?v=J6d03LrHZS8. There is a problem with the  absence of sounds, using Windows movie maker. There appears to be no solution from the interns.   CONCLUSION The hamster took some time to wake up. Two female interns were present. One of them was a single child. She spent much time with this hamster. "Look, she is vomiting the seeds," this lady intern said to me as she observed the surgery and did some video filming of the operation. "The hamster is dislodging the food from her cheek pouch as she is stressed by the surgery and anaesthesia," I told her. "This is a common occurrence. She is not vomiting." Her parents allowed her to keep one cat. Yesterday I told the parents whom I knew from 20 years ago that this daughter  should adopt more stray cats in her apartment. The mother wanted to kill me. "Don't you dare to suggest this," the mother said to me. Many Singapore parents dote on the single child and will tolerate them bringing home stray dogs and cats or buy a puppy. In the end, it is the parents who have to care fore them. Yet yesterday, I met a mother, an old client, from Bukit Panjang. Her 15-year-old Maltese X bought by her daughter long ago is so precious to the mother. The dog came in as she behaved aggressively when carried. The mother knew it was due to false pregnancy. Lots of white milk were present in the dog's swollen mammary glands. This dog still had estrus bleeding 2-3 months ago. At the age of 15 years which is equivalent to 105 years in a human being . This is in contrast to menopause in women at the age of 50 - 60 years. I asked permission for my intern to take pictures for her case study and she said OK. "Don't feed her," I said to the single child as the hamster after surgery, wanted to store the seeds. The plump hamster laid on her back and sipped water from the water bottle while lying on her back, making her laugh. The owner came in the afternoon to take the hamster home. The vet must deliver a hamster alive at the surgery. The anaesthesia is the killing part and this is where a vet's reputation is smeared if the hamster dies on the operating table. No deaths should occur if the anaesthesia is minimal and the surgery speedy, but this cannot be guaranteed. FOLLOW-UP 24 HOURS LATER   1250. Follow up on plump dwarf hamster 64kg with large tumour   Jan 17, 2013 I phoned the Pasir Ris lady at 11.45 am and reached her on her home phone to ensure she does the proper post-op nursing and medication. Sometimes, vets are too busy and will not phone if the mobile phone does not answer. "She is eating and drinking water and active," the Indian lady said. "She is more active than before (surgery). I didn't know she has stopped exercising. I pushed the 1-ml syringe too much and spilled the medicine..." "It's OK as the hamster just needs 2 drops/day for the next 3 days and the syringe has more than sufficient." "Can I shampoo her?" she asked. "I do it every week. She was not happy at first but now she looks forward to the water bath as the weather is too hot nowadays." "No bathing for the next 14 days," I said. The instructions are: 1. Use a facial cotton piece, add clean warm water and clean the surgical wound 2x/day for the next 14 days. 2. Stitches will dissolve on their own in 21-30 days. No need to come for stitches being taken out. 3.  No wood shavings as bedding. 4. No exercise wheel. 5. Give medication 6. No bathing for 14 days A video on the surgery to excise this gigantic tumour by Dr Daniel Sing was produced by the interns:  http://www.youtube.com/watch?v=J6d03LrHZS8. I was the assistant and you can see me doing the IM injection.  There is a problem with the absence of sounds, using Windows movie maker. There appears to be no solution from the interns.

1249. Follow up on 3-year-old cat with recurring FLUTD

Jan 17, 2013

No news is good news. The lady owner didn't phone me. I phoned her at 10.47am to find out about her cat as part of my research on FLUTD treatment. It is best practice to follow up in any case, but many vets don't do it.

I tried to phone the Tampines girl whose male Miniature Schnauzer, born in 2004, had spikey bladder stones removed in August 17, 2007 by her young vet operating together with me. This case study was written by me as she was a veterinary clinic helper and her vet was a younger vet doing his first bladder stone surgery with me.

Her mobile phone seemed "dead". No answer and then a dying sound. I phoned her home and hIer mum said the dog is OK, took my mobile phone for her to call me. I asked her vet to call me. No response. The dog did not have recurrence of bladder stones despite being fed dry food! 



CASE OF THE RECURRING FLUTD CAT
"Totally normal," she said happily. "He was fully recovered yesterday, around 6 days after the problem." The cat was so aggressive when she brought him for treatment on Jan 11, 2013. This time, she was prompt in seeking treatment and so the urine did not look red as at 22 months earlier when FLUTD first manifested. "Continue feeding the C/D + water and no other food," I replied. So far so good.

Follow up provides the vet with feedback on the efficacy of his management and treatment. I sent the cat back home with in-dwelling cathether on the same day.  The cat ripped off the catheter the next day although he had an e-collar. The case is written in a blog a few days ago.

The X-rays do not show radio-dense struvites. Negative crystals in the urine doNOT mean that there are no struvites inside the bladder. In any case, with medication and irrigation of the bladder under sedation, the cat recovered fully 6 days after treatment and the lady owner is most happy. This time, she was prompt in seeking treatment and there was no need for fluid therapy and hospitalisation as occurred 22 months ago.

Many Singapore pet owners delay seeking treatment of difficulty in urination of their dogs or cats and the outcome may not be so favourable as much inflammation and damage to the bladder had been done owing to the delay in seeking prompt vet treatment.

TOA PAYOH VETS toapayohvets.com Date:   17 January, 2013     Focus: Small animals - dogs, cats, hamsters, guinea pigs & rabbits Electro-excision of a large ear wart or tumour in 2 hamsters  Dr Sing Kong Yuen, BVMS (Glasgow), MRCVS Date:   17 January, 2013   toapayohvets.com  Be Kind To Pets Veterinary Education Project 2010-0129 CASE 1. Ear wart or tumour Nowadays, Singapore's pet owners are much more sophisticated and educated. I got an e-mail (below) with 4 images of the hamster's ear wart or tumour from the young couple in a yellow car.   ...i@gmail.com> 12/9/12   to judy   Dear Sir/Mdm, I have just discovered a tiny growth on the ear of my hamster. Attached are the pictures for your reference. I would like to know if there is any treatment for my hamster and the cost of it. If so, pls advise on an appointment date and time. Thank you. Regards, Name of owner   Kong Yuen Sing <99pups gmail.com="gmail.com"> 12/9/12       I am Dr Sing from Toa Payoh Vets. Thank you for your email. The "tiny" ear tumour needs to be removed by surgery and under anaesthesia. The ear canals need to be examined for other growths. The approximate cost is $150-$200 for consultation, anaesthesia, surgery (+/- stitching) and medication. Appointment is by phone 6254-3326. Bring hamster at 9.30 am and it goes home by 4 pm usually. Best wishes.     Sent from my iPhone Although it is troublesome to set up the electro-surgery equipment just to excise a "small" ear wart, I am in favour of using electro-excision as the cutting needle is much more precise in cutting the skin. It takes time to sell my idea to Dr Daniel as he said it would be easier to snip off the wart with a scalpel. We did electro-excision and he is quite convinced it is a useful method as bleeding is minimal. In retrospect, I would have used the circular electrode needle to go under the ear wart and slice it away. The straight needle electrode was used in this case but both achieved the same results in taking out the "small" ear tumour.     Image from hamster owner in the e-mail   Remove distracting objects (right) to avoid wasting time on cropping the image   Cropping required to take out the distracting object     The rule of thirds for better image. The hamster's eyes or body should be at the intersection of 1/3 of 3 horizontal and vertical lines to produce interesting images for the viewer       Straight needle electrode used. I should have recommended a  circular one to loop off the tumour   Very little bleeding and more precise cut when electricity has been use to cut off the ear tumour CASE 2. A DWARF HAMSTER WITH A GIGANTIC TUMOUR NEAR THE LEFT HIP Yesterday, Jan 16, 2013, two older women from "Street 12" came with a 64-g female dwarf hamster aged 1 year and 6 months. She had a gigantic tumour near her left hip. "She's biting the lump", one woman said to me. There was a scab of 2 mm x 2 mm due to the hamster's bite.

1246. Animal activism. An abandoned animal shelter

Straits Times Jan 11, 2013 report: 31 dogs rescued from 'abandoned' animal shelter.

In Singapore, the government had designated some land in Pasir Ris as spaces for dogs. Entrepreneurs bidded for the land and build the kennels or tanks to house the approved species of animals like dogs, cats and fishes. They developed the land and rent out the kennels to private individuals, some of whom operated animal shelters.

However rentals are very high compared to other countries with lots of land. Hence some animal activists find that they can't sustain their operations as they board more homeless dogs. After some years if they don't have financial donations if they could not manage their operations. This would be probably what happened when volunteers at Madam Yap's Shelter in Pasir Ris had not seen its operator for many week and 31 dogs were 'abandoned'.

In animal shelters, the dogs needed to be vaccinated against the serious viral diseases of distemper and parvoviruses. They needed heartworm disease and tick prevention. However, it is extremely difficult to do all these preventive disease program if the shelter has insufficient funds.

A few days ago, I met an animal activist who rented Pasir Ris kennels for $8,000 per month. She had given up this shelter and relocated the dogs or rehomed them.She said Pasir Ris kennels would be taken back by the government in 2014.

Madam Yap's shelter is reported to cost $4,000 a month to operate. This included rent, utilities and a full-time worker but not food and treatment for the sick dogs. Save Our Street Dogs has taken over the place. Their email is sostreetdog@gmail.com 

There is another shelter called Madam Wong's shelter which is still operational, according to my intern who visited Pasir Ris last Sunday, being driven there by her father who doted on her. I had asked her to write an essay on "Animal Activism in Singapore".

 

1245. Recurring FLUTD in a cat

TOA PAYOH VETS toapayohvets.com Date:   16 January, 2013     Focus: Small animals - dogs, cats, hamsters, guinea pigs & rabbits REVIEW A CASE OF A RECURRING FLUTD IN A CAT Dr Sing Kong Yuen, BVMS (Glasgow), MRCVS Date:   16 January, 2013   toapayohvets.com  Be Kind To Pets Veterinary Education Project 2010-0129 Jan 15, 2013 Recurring FLUTD (Feline Lower Urinary Tract Disease) can be very distressful to the cat and the owner. In one sad case, a couple’s cat with recurring FLUTD of more than 2 times died at a veterinary practice and the wife was very sad. This case was recorded reported in: http://www.sinpets.com/F6/20120218FLUTD-cat-death-toa-payoh-vets_Singapore_ToaPayohVets.htm The cat becomes more aggressive as he knows what the vet is going to inject and catherise him again and again. This was what happened to this 3-year-old, male, neutered cat. The brown-striped cat hissed at me as the lady owner placed him on the consultation table. His spinal hairs rolled upwards making a ridge. However, Dr Daniel appeared not to distress him as he spoke to him while the lady owner kept a close watch. Then he held the cat by the scruff of the neck while I injected his back muscles with xylazine and ketamine to sedate him for a proper examination without stressing him more. The cat was catherised and urine was collected. He was X-rayed as Dr Daniel wanted to eliminate the presence of bladder stones.  FOLLOW UP I phoned the young lady owner today at 11 am to remind her that the cat’s diet must be strictly canned C/D for the next 4 weeks to prevent recurrence of blood in the urine and difficulty in urination. DIET & URINATION “What did you feed him before his urination problems?” I asked the young lady who returned my phone call. “Dry cat food. Sometimes canned food mixed with dry food once a week.” “Do you feed cat treats?” “Yes, he loves them. I give him alternate days. Some reddish pellets. I can’t remember the name.” “Does he drink water?” I asked. “He seldom drinks. He will run away when I try to give him water.” URINE ANALYSIS & X-RAYS Date April 7, 2011 (22 months ago) Jan 11, 2013 URINE ANALYSIS Urine colour Red, turbid Yellow, turbid Urine pH 8.0 8.0 Urine SG 1.021 1.026 Urine Protein + + + Blood in urine 4+ 4+ White blood cells in urine 50 30 Red blood cells in urine >2250 1359 Bacteria in urine Occasional Occasional Crystals in urine* Nil Nil X-RAYS X-rays Not done No radio dense stones Outcome Treated by an associate vet of my Surgery. Given 2 cans of C/D. No complaint for the next 22 months Recovered as at Jan 15, 2013. Fed canned C/D for next 4 weeks and review. No treats or dry food strongly advised by me. CONCLUSION * No crystals in the urine does not mean there are no Struvites or other bladder stones inside the bladder. The cat was sent home on the same day after catherisation and irrigation of the bladder. The cat tore out the urinary catheter at home on the second day. On the 3rd day morning, the owner phoned me saying the cat had difficulty peeing. In the evening, the cat was normal and there was no blood in the urine. Owner compliance with the vet's instructions on medication and prescription diet is invariably poor and so the FLUTD recurs in many cases.  Is this case of FLUTD a case of interstitial cystitis (painful bladder) similar in human beings since there is apparently "no struvite stones" inside the bladder? The presenting sign was the cat having difficulty in urination but no urethral abstraction. Will hydro-distension of the bladder, DMSO and other drugs supplied into the bladder resolve the problem of recurrent FLUTD? Nobody knows as the causes of FLUTD in a cat are numerous. ADVICES 1. Owner adds 2 tablespoons of water into the C/D food. Cat does eat C/D but will not drink water given by the owner. “When he was sick in Jan 11, 2013, he drank a lot of water,” the lady said. “But now he turns his mouth away when I give him water!” 2. Continue C/D canned food for at least one month. Water added to the canned food. 3. No dry food and no cat treats anymore.
