1162. A 15-year-old Persian cat

"I went to Vet 1 twice and blood tests were done twice," the man in his late 60s said. "Nothing wrong. I was asked to give A/D by mouth daily and I have been doing it for 2 weeks. My cat is losing weight and not eating. She used to eat well till two weeks ago."

I did an abdominal palpation. The thin kidney meowed when I palpated the left kidney. I advised a blood test. The clues from the owner are important. He said: "My cat would look forward to the dry cat food but after one bite, would not eat."

"Is there mouth ulcers?" I asked. The cat clawed me and objected strenuously to her mouth being opened. I could see one left upper canine tooth gum was much bigger at around 5X the other. Was there a gum tumour causing pain? Was this swelling present at young?

What is the solution? I advised another blood test. But what is the diagnosis and the solution?
This is a difficult case. Dr Daniel said there was a big firm lump in mid-abdomen. Yes, there was one but it could be the kidney or bladder. He was sure they could be intestinal or abdominal tumours.  "An X-ray may show," I said.

I gave the cat an IV drip and medication. Will need to wait and see after the blood test results come in.

1161. A happy father

Hari Raya Puasa story

It is very rare to see a father sending the adult daughter and her dog to Toa Payoh Vets but this father did it. The daughter had bought a very small and thin Shetland collie from the pet shop without the father's knowledge.

"Children do that," I said to him. "They just buy the puppy and bring her home in case you object if she ask you for permission."

"I keep dogs," he said. "I don't object. But she has bought a stunted weak and thin Sheltie."
"Some  mothers do object," I said. "Could it be your wife?"
"Yes," he said. "In the end, the parents have to look after the dog. Why did she buy such a poor specimen?" He could easily have paid for a good quality puppy. In any case, this Sheltie was 9 months old and was at the kennel for some months, without a hope of a sale.

"Women are kinder to the disadvantaged and sick animals than men," I said. "What would happen to all the weaker dogs if every woman buys just the pick of the litter or nothing? I will examine her heart and lungs and do the blood test to check whether the kidney and liver are ok."

The Sheltie objected strongly to me examining her mouth. She even bit my assistant. "There's gingivitis. See the red line at the gum-tooth level. It is painful. There is tartar and the 4 puppy canine teeth which had not dropped off. Take antibiotics for 7 days and come for dental work."

So, today Hari Raya Puasa was the appointment date. I was taking pictures of the hamster patients (one with skin behind the head and above the neck very itchy and the other one with pus in the swollen right eye). The father and daughter came with the Sheltie.

"The dog is more active and eating after the antibiotics," the daughter told me. "The gums are less inflamed and the red line between the teeth and the gum had vanished by 90%". Under general anaesthesia, the 4 puppy canine teeth were extracted by Dr Daniel.
"Are you a happy father now?" I asked the gentleman who is probably the same age as me. "The blood test confirmed no liver or kidney or blood system problems. This Sheltie is just born small sized."

Yes," he nodded. I was most happy for the dog too. She had lived inside the pet shop for at least 9 months and had difficulty eating due to the obstruction and pain from the retained teeth. 



 

1160. Follow up: A happy Hari Raya Puasa. The constipated Hougang cat

Today, Freiday Oct 26, 2012 is Hari Raya Puasa, breaking the fast for the Malays. I was at the office at 8.45 am.

It was too early to phone but I would not have time later. I dialed the handphone of the well-groomed and well-dressed Malay lady with the 2-year-old Hougang cat that came yesterday evening. Her cat was spayed by Dr Daniel 5 days ago. But Nike was meowing and panting yesterday afternoon at around 4 pm. I could hear the sounds of the cat over her phone call. "She has not pooped since the spay," the lady said. "What shall I do? I am worried about this non-stop panting and panting."

"I advise coming to me for examination and to give an enema," I said. "If you wait and see, and if the cat's panting and meowing worsen after midnight, you will have to pay a lot of money for emergency treatment!"

At 7 pm, the cat came. She was normal and her panting had stopped. One cool cat not bothered with the dogs barking in the waiting room. "My husband is in the car outside," the lady said. "I am not afraid of dogs. Shall I go home since the cat is now normal?"

This was a tough question. If I said yes and the cat's symptoms returned past midnight, the lady would have to pay 3-4X normal vet fees. She would be more stressed as she loves this cat very much. Non-stop meowing is as stressful as non-stop panting for a cat owner. The neighbours may be disturbed too.
"It is better than I sedate the cat and put in an enema tube in her anus," I said. "If the cat is not fierce, I would not need to sedate. However, this cat scratches and if I give the enema without sedation, there will be no second chance."

So, the lady with her reddish brown silky Malay headwear and clothing held the cat, placed on my operating table,  tightly on the chest area. My assistant Min held the right hind leg while I squeezed into the narrow corner looking for the back muscle of the left hind leg and not intruding into the personal space of the lady. I injected. The cat jumped a bit but her owner held tight. "Put her back into the carrier," I said. In the owner's presence, the domestic cat seldom becomes frightened and attack the vet. I asked the lady to wait in the waiting area.

In 10 minutes, the cat was sedated. My assistant Min pressed the rectal area. A 1-cm brown piece of stool came out. There was no more. "Hold the cat's backside upright," I said to Min. "Pump in the enema fluid." I put the cat back into the carrier.

"All the stools have come out?" the lady asked while her husband patiently waited outside in his parked car.

"No," I said. "All systems including the intestines shut down during sedation. The stools will come out when the cat is awake."

"When?" she asked.
"Most likely next day."  Sedation:   Xylazine 0.15  Ket 0.6 ml IM, 2 year old



FRIDAY OCT 26, 2012 I phoned the owner.  Hari Raya Puasa. Her husband asked her to answer my phone call.

"How's Nike?", I asked. "What time did she wake up from sedation?"
"He woke up at 2 am. She vomited 5X. Food and water."
"What time did she wake up in the morning?"
"I woke up at 6am and I saw her walking around the apartment," the lady thought I was asking about her waking up. "I gave her food and you know what?"
"What happened?" I asked.
"She pooped a lot!"|
"What do you mean a lot?" I asked.
"A very long piece. From the end of my middle finger to my wrist! Jhard and solid. And two small pieces of the size of my thumb!"

"Was there any hair inside the long stool?" I asked.
"I did not check," she said. "But there was a big hairball when she vomited at 2 am."

"Does your cat groom a lot?' I asked.
"What do you mean?"
"I mean every few seconds, she would clean her fur."
"No, but she would groom for a long period of time when she is not playing with me."

This was a most happy cat owner on Hari Raya Puasa. She had agonised for 2 years as to whether to spay her cat or not and when she decided, the cat would not take the medication. She had asked her husband to collect some antibiotics and pain-killers as the cat threw out 50% of the medication. So the husband came on the 3rd day after spay. And on the 4th day, this cat meowed and panted in the afternoon, further worrying her.

It was a happy ending. If I had asked her to "wait and see", the constipation would be harder to treat as the stools would be very hard. The cat would feel the pain of passing motion and that could be why she panted. I had asked her to feel the hard long stools of the colon when the cat was sedated yesterday. She could feel it, but nothing as impressive as the passage of the hard stools this morning! 

As for the spay wound, it was very clean as the lady showed to me. Not a bit of inflammation as she had taken great care to give her cat medication and pain-killers as instructed. Most owners would just give up.










       

      

The Brazilian girl's hamster has a swollen eye

Dwarf hamsters are quite popular in Singapore in 2012 as Toa Payoh Vets see more hamster cases nowadays. Yesterday I asked a Japanese mother on how she selected Toa Payoh Vets.
"I google hamster vets," she said that not all vets treat hamsters. "I saw your webpage."
What she said is true in my backyard. One of my associate vets prefers not to perform hamster surgery at any time as they are such fragile anaesthetic risks.

"No, you did not," the pretty and fair 8-year-old Brazilian daughter said. "You google Singapore vet."
"I did not," the Japanese mother replied. "You saw Singapore vet. I type hamster vet in Singapore."
"Children nowadays are very observant and watch what mothers do," I was much impressed with this little girl's close bonding with the mum. "How old is your hamster?"
"We bought her in January 2010," she said.
"That would make her 2 years and 9 months old," I noted that this hamster with the left swollen eyelids was not so active.
"Dr Vanessa will examine the hamster with me," I said. "Does she bite people?"
"Sometimes."
Dr Vanessa wore her glove in her right hand to weigh and examine the hamster's swollen eye. She pressed down the lower eyelid. Pus oozed out.
"We have to hospitalise the hamster for one day, anaesthesized her to remove the pus from inside the eyelids," I said. "Anaesthesia will permit us to do a proper job of lancing the abscess."
Some vets will prescribe eye drops but it will not work in this case as the eyelid abscesses are large.      

It is best to equip yourself with the appropriate surgical tools for hamster surgeries as the ones for the dog and cat are too big. See pictures below.

Health check on a big-sized 13-year-old male Jack Russell

The lady owner was studying medicine in the US. When she came back for a holiday, her Jack Russell was scratching his eyes till the eyelids bled, his chest so that it was red and his penile skin till it was bald, the four paws with deep red blood in between the toes and on the toes. What was the cause? Yet the ears were spared but I saw crusty lumps on the edges of the left ear. Scabies? Allergy? Demodecosis?  Skin scrapings were negative.

Blood test - monocytes higher than normal at 11.2%.  Other values are normal.
Calcium and uric acid within normal range. Liver, kidney, joints normal.
Dental scaling done.





X-rays showed no radio-dense urinary stones but there is possibly one in the bladder area. It is hard to tell on the lateral view of the X-ray.
Urine showed calcium oxalate crystals
pH 6.5,  SG 1.022,  Protein 2+, Blood trace, Crystals calcium oxalate occasional, bacteria occasional.

The "occasional" presence of calcium oxalate does not mean there are no urinary stones. Absence of crystals does not mean there are no urinary stones. Much depends on the clinical signs of blood in the urine. The dog was furiouslylicking its penile length till the area was red and hairless. This was unusual. There could be difficulty in urination but nobody knows as the caregiver owner was studying in the US.

FEEDING OF U/D CANINE NON-STRUVITE URINARY TRACT HEALTH

Indications: Urolithiasis due to calcium oxalate, urate and cystine stones; end-stage kidney disease
Decreases purine intake and uric acid excrerion, which lowers the risk of forming urate crystals and uroliths

Monitoring Urine SG, urinarypH and BUN will let the vet know the food's effectiveness and owner compliance. Dogs fed on this diet commonly show unusual lab values like USG <1 .020=".020" bun="bun" dl="dl" mg="mg" p="p">
Long term use: Check for protein depletion as U/D is a low protein diet to decrease urea production,  but the protein level is suitable for maintenance of the adult dog. Advise a fasting serum chemistry profile and ECG every 6 months.

1155. A hamster from Italy


On Sun, Oct 14, 2012 at 7:21 PM, Valentina C...@gmail.com> wrote:
Dear Sir/Madam,

I am Valentina and I am writing from Italy. I have a one-year-old dwarf male hamster and he has got a problem; I only realized it yesterday. I follow from here all your surgery cases and your successes, the photos and the articles on the web site, so I thought it was better to write down a line to have an advice from you, because you are experts and I admire your job.


This is my first hamster and I do not what to do, really, I am desperate, because so far we had any kind of problems. The problem is related to its lower area of the body, and it's like an abscess or a tumor or something like that because it is a hard distended underskin lump near the penus.




Here in Italy the vets are closed on saturday and sunday so I medicated it as I could on my own, doing some chamomile hot packs.


Do you think he probably will go through a surgery? What am I supposed to do? Please help me, I'm sending you some photos. Talking about the hamster, he is acting as normal, it is not weak, he plays, eats, sleeps.... Thanks a lot, you really do not know how important is to me if you answer back. Sorry to bother you.

Your sincerely,
Valentina C.
 
EMAIL REPLY FROM DR SING DATED OCT 23, 2012

Thank you for your email. It is hard to see from your 2 images what is the affected area you mentioned. It is best to consult your vet.
 

1154. The urinary stone Schnauzer barks and eats at 6.47 pm

Tuesday Oct 23, 2012  6.47 pm
I asked Dr Daniel to bring JJ out for a walk at 6 pm. Evening sunset, tranquility. This dog had not wanted to eat since my surgery on last Saturday and I am most worried. The owners visited her every afternoon.

Dr Daniel said: "The owners say that this dog does not eat after surgery and it is common."
JJ walked out with a spring in her step. She peed outside and the urine was yellow and has no signs of blood unlike this morning.

Suddenly she barked at a jogger.  This was excellent news. A dog that barks suddenly at joggers is on the road to recovery. Dr Daniel took off her e-collar and gave her canned food. She ate and my worries of the post-op decline in health vanished. She walked up and down the back room looking for Dr Daniel. She sat on her back. "Put her back into the cage," I said.

1153. Retrospective study of the vomiting Schnauzer with urinary stones in kidney and bladder

Oct 23, 2012  8.56 am

The Schnauzer, F, 4 years is still not eating. But I had given her the IV drips including glucose and some hand feeding of the L/D diet. She would just lick a bit and not swallow, according to Dr Daniel who was assisting me in this case. She could sit up and look at me with sad eyes. The only good news is that she does not vomit anymore, unlike the 5 days and on the day of surgery.
I am now reading the voluminous records of previous vets and summarise the findings below:



1.  Nov 14, 2009
Health check and vaccination

2. Sep 28, 2011
Ear infections treated.

3. Feb 18, 2010
Intermittent cough when sleeping. Vomits mostly fluids. Spay and dental scaling done.
4. Nov 8, 2011
Urinating blood. Bladder stones palpated. X-ray. Cystotomy to remove stones
Stones removed digitally and by retropropulsion
Post-op X-ray - no stones in the bladder

5.  Nov 11, 2011
Cystostomy to remove bladder stones. Bladder entry swab c/s to lab.  Heavy growth of Coagulase-negative staphylococcus
Stone analysis to Minnesota. Stone and shell 100% magnesium ammonium phophate (struvite)

5. Nov 13, 2011
Discuss options
1. See if recurrence, then start food trial
2. start food trial

6. Nov 14, 2011
Follow up. Owner said dog vomited few times at night on the 3rd day afer surgery.
W/D canine dry

Nov 19, 2011
Review.  Owner says some vomiting on 3rd day of surgery might be due to eating something downstairs. No more vomiting. Advised owner to monitor for uroliths. Pet is female and there is the option of urohydropropulsion. To change from S/D to W/D as the breed is prone to pancreatitis or RC urinary s/o

Dec 2011, Feb, April & Jun 2012
W/D canine 8.5 lbs dry


Jul 22, 2012
Straining to urinate and leaking urine for 2-3 days
Bladder stones palpated and seen on X-ray
Unable to get urine for analysis
Treat UTI first, try to dissolve stones with 1 S/D can/day and review in 3 weeks.
Blood test. low RBC, HCT, HGB.
High total WCC 22.4 (5-17), N 18 (3-12), M 1.4 (0.16 - 1.1)


Aug 12, 2012
Multiple large bladder stones on X-rays. Vet 1 advised surgery. Owner did not accept advice. Went to Vet 2 who treated with antibiotics, acidifying tablets and then S/D

Oct 19, 2012
A few days ago, the owner asked me whether he could buy medication from Toa Payoh Vets as the Jurong vet was too far for him to collect medication and S/D.
I advised another X-ray and blood test as Vet 2's 2nd x-ray already showed multiple stones in August 2012 and the owner said that the urine was very smelly.

The dog started vomiting for 5 days before Oct 19, 2012. Test showed bacteraemia and toxiaemia with low platelets. Dog was operated on Oct 19, 2012. Around 13 stones removed from bladder.  Normally I don't do exploratory laparotomy in cases of bladder stones as this was the case. However, I checked the stomach and intestines for foreign bodies as there were radio-dense objects inside the
intestines on X-ray taken by me.


Oct 23, 2012.
Dog on drips and medication daily. Not eating. Alert.
At 10 am I asked Dr Daniel to take her out to have some sunshine. She peed red blood and pooped soft brown stools. No vomiting. The blood could be from the chronic cystitis of the bladder wall as stones were left too long. Also, possibly from the bladder bleeding.
So far, the dog is walking and alert. No fever. Just would not eat.

Oct 23, 2012  10.09 am
That was when I found a 3x enlarged purplish red left kidney with prominent blood vessels in its capsules and as big as a golf ball compared to the normal right kidney. Some bleeding spots near this kidney and brownish stained spot in the omentum. This was serious as the left kidney could be bleeding. There was anterior abdominal pain on palpation earlier.

She would walk about, drank water and sit on her backside. Some panting.









CONCLUSION
Each vet has his or her own advices on the management of struvite stones to prevent recurrence after surgery. Vet 1 advised S/D and W/D dry which is also indicated for struvites. For this dog, I have advised:

1. 2-3-weekly urine analysis
2. X-ray 2 monthly for 3 times
3. S/D canned food for 4 weeks followed by C/D canned food for 3 months with the usual urine tests and X-rays.
4. No dog treats or other food and no DRY dog food of any kind.
PROBLEM: What about the enlarged right kidney with the stone?
If the stones are small and packed in the renal pelvis, I hope they will pass down the ureter to the bladder and gets peed out. Wait and see as the dog is now active and starts to eat.

Due to economics, contrast radiography is not advised for the time being. Prevention is better than cure and for struvite stones in Miniature Schnauzers and other dogs, 2-monthly urine analysis and at least one X-ray of the abdomen for urinary stones are best done. Seldom do owners do it as monitoring requires discipline and planning.

1152. A pet rat in Singapore fractures his tooth

Unusual case as I seldom see pet rats as Singaporeans don't keep pet rats.

October 18, 2012

This handsome black and white rat fractured the lower gum end of his low right incisor teeth as he chewed on the bars of his cage. Hamsters and rabbits commonly do that too. The tooth did not fracture completely and so he would be feeling the pain every time he tried to eat. His owner quickly took him to the vet and I was surprised to see my first pet rat patient in over 30 years of practice.


What is the solution? Clipping off both lower incisor teeth and levelling them.  Now, this young rat strenuously object to any human opening his mouth even to examine the teeth. So, I needed to put him under anaesthetic isolflurane + O2 gas and clip off both lower incisors to the same gum level. His fracture was at the gum level.




 
 
 
 
FEEDBACK FROM THE OWNER ON OCT 23, 2012
Dear Dr.Sing,
Thank you for the photos. S... is recovering well. Today - for the first time since the procedure - he was able to chatter his teeth (which he normally does when he's happy). He's also been able to start eating his regular Lab Blocks food again, albeit very slowly and with some difficulty as the teeth have just grown back a little bit. We're supplementing his diet with softer, easier to eat foods like vegetables and he doesn't appear to be losing an unhealthy amount of weight.
