1420. Divine intervention?

Yesterday I spoke to my client whose heart had stopped beating for over one hour in 2008 when he went in for a surgery of his middle ear. Emergency resuscitation by the medical team revived him but now he feels deep chest rib pains. His heart is OK.

"My ECG reading was flat as a straight line," he said. "I was dead."
"Did you see bright lights?" I asked.
"I saw bright lights, blue skies and hear hymns."
Was it divine intervention for an athesist? Was there medical negligence as his medical form and his hand bracelet stated he was allergic to augmentin. Yet he was given augmentin prior to surgery? I am glad he is alive. His dog which was diagnosed with paraplegia by Vet 1 was massaged and managed to prevent bed sores survived to 15 years of age. He started to walk "but hopped" after home nursing. Recently he had kidney failure and I had to euthanased him. The client came for a death certificate and I asked him about his health after being "dead" on the operating table. I was most happy he was alive.

Doctors are not Gods. They make mistakes and will continue to make mistakes. Some mistakes cause deaths of patients. It is important to adopt a systematic procedure to check for drug allergies before anaesthesia and surgery and to ensure drug dosage is not above requirements.

1419. Update: Anal wound closed up by Dr Daniel

"The old dog's circum anal wound is very big," my intern Ms Toh said to me. "But I can't illustrate. It is just very big!". Sometimes I try to motivate my intern to be more interested in the various surgical conditions in dogs. After all, she will be studying vet medicine next year and internship gives her real life cases.

"Is it a 12 to 6'oclock tumour around the anus?" I persisted.
"I don't know," she said. From Dr Daniel, it was this massive size. The wound was large as a big piece of the skin with tumours was removed and stools just lodge inside this big wound.

"This wound will never close by granulation because stools keep contaminating it," I said to the owner and to Dr Daniel. "A skin flap has to be made to stitch the anal sphincter to the skin." The owner consented to the surgery and even phoned yesterday to ask whether it was done. "It is being done now," I said. The surgery was done by Dr Daniel. No more defect or gap. Wait and see.

1418. Large wounds

In some cases, I had to intervene when surgical wounds do not close and the owner will not want to pay for wound stitching..
 
Case 1. The kitten had a big left neck abscess. The pus was cleared and the wound stitched by my associate vet. Yet the stitch broke down. The owner did not want to pay for further stitching. "The wound is 3 cm x 2 cm," I said. "A large wound exposing the neck muscles and the big neck veins. Yellow pus and scratching will persist. Smelly later due to bacteria and hair trapped inside. Very itchy for the kitten.  Stitching must be done." I offered him a below cost rate to get the kitten wound stitched up. The kitten recovered well.

 Case 2. The old cross-bred had a massive circum-anal tumour from 6 to 12 o'clock. My associate vet excised the whole tumour. Now a big hole. The anal skin was gone. The anal opening shrank inwards. So the dog pooped and the stools are entrapped in this hole. What to do?

The owners let the maid look after the dog and did not seek treatment. The lady friends of the owner came to visit the dog. The owner had denque fever and could not turn up.

"It is not as if this dog is cuddly," the lady friend explained why the circum-anal tumour was permitted to grow so big, such that there is a big hole now. "The maid did not inform us." What is the solution? Re-stitching is the answer but there is no skin.

1417. Update: The Chow Chow's backside hair has grown

There was another Chow Chow who bit her right backside bare and started losing hair. I remember this owner as he keeps beautiful arowanas displayed in big tanks in his office and beautiful koi. He has two pretty Golden Retrievers. And a Chow Chow.

The carer had gone back to China for a holiday and the Singapore employee groomer had resigned. "How's the dog?" I asked the brother of the owner. I had the dog clipped bald too and gave the skin disease treatment.

"I don't know," he said as he brought his dog for skin disease treatment. Later he checked and told me the hairs had grown back.   

1416. Update: The Chow Chow is a Sharpei? Skin disease

May 15, 2013

This Chow Chow looked very much like a Sharpei when she was clipped bald. But she looked like a Chow Chow when her hair grows back. I saw the dog yesterday, around 2 months after treatment for skin diseases and passing blood in the urine. She had skin diseases for several months and was referred to me by my wife's ex-colleague Susan. 

It is very difficult to get dog owners to return for a review of the skin diseases. After all, if the dog has recovered, why see the vet? It was pragmatism in Singaporeans.

Yet, the skin may not be fully recovered if the dog has some leftover skin diseases. In this case, the Chow Chow has no more "dandruff" and the hairs are sturdy and not falling off. Yet the dog had started scratching around the ears.

"The ears are full of wax," I showed the cotton bud tip sticky with yellow brown wax. The neck hair had bloomed. Wetness was due to the dripping of water when drinking from the water bowl. The owner brought a urine sample for testing as previously the dog's urine tested for struvite crystals, high pH of 9.0 and presence of blood and bacteria. I prescribed 12 S/D cans to dissolve the crystals but the owner did not return for more. "The dog vomits the S/D," the young adult daughter said. Yet on further questioning, the dog did eat at least 10 cans but started vomiting the 2 cans later.  There were no phone calls to me for advice.


"Taking S/D to dissolve the struvite crystals prevent them becoming stones," I explained. "It must be taken for 1-3 months, not 10 days."

I did not want to do hard sell. I advised spaying and entropion surgery of the two eyes. The Chow Chow had been peering from 3/4-closed eyelids for the past 3 years and the entropion surgery would have resolved the problems.

"We don't want the dog to go under anaesthesia," the young adult daughter said. to me.
"With this continuous eyelid rolling inwards irritation, the cornea becomes infected and ulcerated. In later years, you have a blind dog as the cornea becomes black from pigmentation and the dog can't see. It is important that the Chow Chow has her eye surgery. As for the spay, if you don't want it, that is OK."

Ignorance of the safety of modern anaesthetics is a reason for no spay and no eye surgery. This can't be helped.

1414. Saturday May 11, 2013's interesting case. A 3rd opinion - inoperable oral tumour

 
The 13-year-old brown cross-bred was slim and trim. "Her tongue slips out from the left side of the mouth when she is panting," the owner told me. "She is not eating much now." He was seeking a 3rd opinion from me after surfing the internet.

Two years ago, there was a pea-sized growth in the inner cheek. His vet had sent a biopsy to a  histopathologist and the diagnosis was adenoma of the salivary gland. The report stated that it had few numbers of mitotic cells and would recur since this tumour was locally invasive. His vet advised "debaulking" and cutting off the right jaw.

The owner would not agree. So his vet referred him to the competitor who said that he did not think the histopathological results were correct. "He recommended CT scan and chemotherapy. He also said a sample should be sent to the U.S," the owner told me.

However nothing was done as his advice was similar to the first vet, that is, to cut off the jaw and the dog would adjust to this loss. He prescribed clinadmycin and meloxicam as well as codeine recently.

The oral tumour now was more than 5 cm x 3 cm x 3 cm and two more swellings of 1 cm x 1 cm and 1.5 cm x 2 cm below the right lower jaw on the underside of the neck had developed.

"Was an X-ray done by the 2 vets to see if the jaw bone was involved?" I asked.
"No," he said.
"As the growth of the tumours is fast recently, it is likely to be cancerous."

"Due to the massive size and spread, there are inoperable tumours. With surgery, there will be recurrence within weeks."

The owner agreed not to have surgery. The other sibling had no oral tumours. He showed me his smartphone images of his two slim and fit female dogs and we had a good chat on their behaviours.

In retrospect, would early excision of the lump at the back of the tongue prevent spread two years later? Though unlikely as the histological report said it was locally invasive and likely to recur, this might slow the increase in size. However, this is very difficult to predict. Removal of the jaw bone is not acceptable by all dog owners, in my opinion as they could not imagine how the dog would eat her food. Personally, I would have got the small oral tumour excised but warn the owner of the recurrence.

1413. Sunday May 12, 2013's interesting cases. The senior citizen man has a swollen foot

Sometimes, the vet has to care about the client's health although this is the domain of the medical doctor. The couple brought two Bichons with itchy necks and rashes all over the body for consultation. 

As there are over 50 vet practices now, I rarely get cases from Tampines which is near Changi Airport and is a half-hour's drive to Toa Payoh Vets and so I was surprised to see this couple. They wanted to buy a bottle of multivitamins in the belief that this would cure the itchiness. They had bought Neoderm cream which was effective.

"It is best to see the dogs," I explained to the couple. Times are hard for senior citizens and if the skin diseases cannot be cured after two consultations, then self-treattment is usually done by many Singaporean dog owners.

Both Bichons had extensive redness below the neck and on the face. Rashes scattered all over the body except the ventral part. The dogs wore clothing to prevent scratching but this was futile. From the signs, the main cause would be ear itchiness leading to continuous hind leg scratching and scratching of the flanks and self-inflected biting of the back and body. 

"The skin has been injured by the daily scratching. Skin wounds and rashes become infected over the months. To the owner, it seems that the skin is badly infected and he buys oil,cream and shampoo over the counter to treat the disease. Without success if it is a fungal and bacterial and yeast infection."

I had the dogs clipped bald, the excessive ear hairs plucked. As the gentleman was wearing slippers with straps over and across the foot, I noted that the left foot was much swollen. The swelling under the cross straps was absent due to the pressure. "I can't wear shoes and these sandals are useful as I can adjust the width as my foot swells."

"You will lose your foot if you continue," I said. "How long and have you seen a doctor?"
"Just 8 weeks. The doctor said I could have gout or arthritis and gave me some medication."
"I think it is likely a tumour - a nerve sheath tumour at the ankle growing and obstructing blood flow," I said. So, the fluid from the blood vessels of the obstructed area spills out and accumulate under the skin, leading to such a swollen foot. If you delay further, you lose this foot and will be hopping around on one foot. Have you got an MRI  or CT scan of the foot?"

He had not. He would go to the polyclinic to get an appointment to see the specialist. "By the time the specialist sees you under this system, it will be a few months. Your foot may become gangrenous and need to be amputated."

I advised him to see a private specialist at the Singapore General Hospital. "How long do you think you will live?" I asked this 65-year-old man.
"Men live up to 85 years."
"Men live shorter lives than women," I said. "Many have died before they reach 60 years of age, owing to poor health."
He agreed to see the private specialist next week as he said: "I believe the swelling has a more sinister cause." I guessed his wife was grateful for the advice. Men are inert when it comes to their health and in this case, an MRI would have detected the cause and he might save his foot.

1411. Follow up: Cat with bladder stone surgery

 
Friday May 10, 2013

"Remember the cat? You said it would die under surgery!" the busy gentleman drove over to buy the C/D dry food and canned food for his cat after ensuring that these were available. He had ordered earlier and deliveries by the Science Diet supplier arrive only on Thursdays of the week. His cat had run out of the canned food.

"Yes, I remember your cat" I said. Cats with bladder stones are relatively a rare occurrence in Singapore and this was one with impending kidney failure according to the vet who had taken blood test. The owner wanted an immediate surgery since his vet who diagnosed the condition would not do it owing to lack of experience while the senior vet had a full schedule of surgery.

It is best not to operate on a cat with impending kidney failure as the cat would die. I waited one day so as to give antibiotics since the other vet did not do it. The cat die not die under surgery but the owner never forgets the "cat will die if operated upon" informed consent.

"How's the cat?" I asked.
"Put on weight. Back to his naughty pesky self now, as normal." he said.
"Can I keep the prescription diet inside my car as I cannot go home immediately?"
"No," I advised finding a covered car park.
He was such a busy person but he took time off to buy the special food for his cat before the stock runs out. His cat eats one can per day. Most Singaporean cat owners will not be bothered. He told me his cat will eat the canned food whether it was refrigerated and cold and also any brand of cat food. This is surely an unseal cat as most cats are fussy.

I am glad his cat is normal and there is the chance to follow up with him. I told him that the supplier will deliver to his home if he pays me first for the next order.  "The supplier does not want the hassle of collection," I said. He would transfer the money to my account electronically first. Actually he could have bought the food from the vet nearby but he did not do so. The vet was the one who diagnosed the bladder stone and I am sure she would just sell him the special diet.

Pet owners have their preferences of vets and it is up to the vet to build up the relationship of trust and goodwill as there is nowadays a vet round the corner. Owners have to make an extra effort just to go to a vet "far away" just to buy the special diet which is easily available at most vet practices in Singapore.

  An informed consent must be given prior to anaesthesia and surgery. It should be in writing but in this case, I emphasized orally the high risks of death since the cat has kidney disorders based on blood tests and surgery could not be postponed for a week. I suspected the cat could suffer from a bacterial nephritis based on high total white cell count so a pre-emptive antibiotic injection which the other vet did not administer would increased the chance of success.

In this case, the odds were in my favour after a Baytril antibiotic injection SC 24 hours ago. The cat survived the bladder stone removal surgery. Unfortunately for me, the owner never forgets my warning that "the cat will likely die during the anaesthesia and surgery" and will remind me whenever possible. Many vets will suffer my situation when the cat they say will die from a serious disease lives up to a ripe old age!

He had Hobson's choice and I had been fortunate that the cat did not die on the operating table and the fact that this owner detected loss of appetite in less than a week. Many cat owners wait and see for several weeks before they seek vet consultation.

No vet can predict the surgical outcome in taking on high-risk anaesthetic cases. Use evidence-based medicine always but sometimes the owner's financial situation prohibits blood testing and in this situation, it is difficult. In such situations, use minimal injectable sedatives, use IV drips and isoflurane only.
