Hook - "The nose developed a small red lump initially," the gentleman said. "Now it is a large swelling. Is it a tumour?"
This 2-year-old dwarf hamster is the gentleman's beloved pet in Singapore. The owner is very busy as he works hard in the financial district of Singapore (video footage of Singapore's downtown if possible).
He was full of energy, greeting the owner when he comes home from work in the business district.
He had not been sick till now. As dwarf hamsters live up to 2.5 to 3 years, he is considered old. With old age, tumours may develop. Has he developed a large tumour? Is there a cure?

Title: A 2-year-old dwarf hamster has a large red nose - nasal abscess
INTRODUCTION
Define: Abscess
DIAGNOSIS
Physical examination - soft swelling about 8 mm x 5 mm x 3 mm in size. Likely to be an abscess (video footage of discussion with owner during consultation. Use whole footage if necessary).
DIFFERENTIALL DIAGNOSIS
Tumour, abscess or abscessed tumour.
1. A tumour is possible as the hamster is aged. It will be hard
2. An abscessed tumour will have hard and soft areas.
3. An abscess is feels soft if it has existed for some days. .
TREATMENT
Gas anaesthesia is necessary to enable pain-free procedure. It also prevents stress and sometimes death due to the struggling and stress of restraint and surgery. A scalpel blade incises around 10 mm into the midline of the nose and the pus is drained. (Video without the gory blood).
POST-OP
24 hours after surgery, there is residual pus expressed from the wound in the morning. This has been removed using a cotton bud tip. The wound closes. The hamster goes home in the afternoon. He recovered fully in one week.
CONCLUSION
Prompt veterinary attention results in a clean incision using scalpel and rapid recovery. Delays will result in loss of appetite, possible death. The untreated abscess will rupture into a large irregular shaped wound, spilling blood, pus and bacteria onto the face and mouth. The hamster will lick up the pus and swallow it, leading to loss of appetite from illness and possible death.
A 12-year-old male neutered Miniature Schnauzer had not been eating for a week. He was certified fit to travel from the USA to Singapore 3 months ago. He had been "coughing" phlegm for some days. He is not on medication including steroids.
He was fed a BARF (Biologically Appropriate Raw Food Diet) for around 2 months and then home-cooked chicken diet for the past month. Dog treats were given. Physical examination Thin, no fever. No icterus. Heart sounds muffled. Slight anterior abdominal pain. No abdominal masses were palpated. Radiography The heart and liver are not enlarged. The liver size and shape are normal. No large abdominal masses.
Blood test. 1. High total cholesterol. Triglyceride level is normal. 2. Low fasting glucose 3. High ALT and AST (markers of hepatocellular damage). Alanine aminotransferase (ALT) and aspatate aminotransferase (AST) are liver enzymes.
ALT 3722 U/L (10 - 109) AST 587 U/L (13 - 15) 4. No leucocytosis or leucopaenia. Unlikely to have leptospirosis or viral infections but this cannot be ruled out. 5. Kidney function is normal
Ultrasonography (focal liver lesions, diffuse liver disease or biliary disease like cholestasis), evaluation of urine or serum bile acids and liver biopsy (fine needle aspiration, laparoscopy, exploratory laparotomy) were not done owing to financial constraints.
On a routine biochemical profile it is
important to note the liver function tests including bilirubin,
albumin, glucose, BUN, and cholesterol.
Conclusion An increase in total cholesterol, ALT and AST liver enzymes indicate liver disease in the dog.
Persistent
ALT increases should be investigated when they are greater than twice
normal. The most important diagnosis to make is chronic hepatitis. Early
diagnosis and prompt therapy improves patient survival
Some cases of liver failure can be reversed. The causes can be hepatic or non-hepatic . The laboratory tests must be correlated with the history, physical examination to arrive at a diagnosis.
In this case, the dog is not overweight. The high total cholesterol might be due to the diet including dog treats.
Miniature Schnauzers are a breed predisposed to liver disease during old age. A common condition in the older dog is idiopathic vacuolar hepatopathy resulting in elevated ALP.
In conclusion, 4 categories of causes of elevated liver enzymes in the dog are: 1. Primary hepatobiliary diseases. 2. Secondary to extra-hepatic diseases 3. Benign condition (hepatic nodular hyperplasia) 4. Progressive condition (chronic hepatitis, neoplasia).
Advices to the old dog owner Repeat
blood test in 4 weeks. If liver enzymes are elevated, further tests are
needed (ultrasonography, bile acids, wedge liver biopsy) to check for
chronic hepatitis, hepatic neoplasia, benign hepatic nodular hyperplasia
and diffuse vacuolar hepatopathy . Low fat high fibre quality maintenance diet. Hand-feeding is important. Liver support therapy eg. Zentonil
VIDEO
24 HOURS after treatment
Day 3 of treatment. Mild jaundice is seen in the eye sclera which is stained very light yellow.
Day 4 of inpatient Can stand, walk, poop. On I/V drip. Not eating the K/D and A/D today. Hand fed. Urine testing. Eye sclera looks more yellowish.
Hyperlipidemia
is a condition in which the amount of fats (also called lipids) in the
blood are elevated. The most important lipids are cholesterol and
triglyceride. Hyperlipidemia is a common and under-diagnosed dog health
problem that can negatively impact health and longevity.
Several metabolic diseases demonstrate hyperlipidemia, including diabetes, hypothyroidism and Cushing’s syndrome. Some dog breeds are genetically predisposed to hyperlipidemia.
Hyperlipidemia does not normally lead to heart disease, but can decrease lifespan and cause obesity, neurologic and metabolic issues.
Genetic predisposition – Miniature schnauzers and Beagles tend to be genetically predisposed to hyperlipidemia.
Symptoms of hyperlipidemia can include:
Decreased appetite
Vomiting
Diarrhea
Abdominal pain
Bloated abdomen
Cloudy eyes
Fatty deposits under the skin
Hair loss
Itching
Seizures
Diagnosis of High Cholesterol in Dogs
You may want to eliminate all table scraps and gradually switch your pet over to a low-fat, high-fiber dog food as diets high in fat are a common cause of hyperlipidemia. However, results from diet changes can take 6-8 weeks.
If you are seeing symptoms associated with hyperlipidemia in your pet, you will need to visit the veterinarian to determine the underlying cause.
A full history of your pet and a thorough physical exam will determine what diagnostic tests may be necessary.
Laboratory tests used to help diagnose hyperlipidemia and identify any underlying causes can include a complete blood cell count to detect blood abnormalities, biochemistry to examine kidney and liver function, urinalysis to examine urinary tract function, a thyroid test to measure thyroid hormone production, a CPL (canine pancreatic lipase) assay to measure lipase levels and detect possible pancreatitis, lipid tests to examine levels of various lipoproteins to aid in locating where the metabolic issue lies and a cortisol test to measure adrenal gland function.
The pet must not eat any food or treats 12 hours prior to the cortisol test. Morning appointments are best
-----------------------------------------------
The common bile duct is a small, tube-like structure formed where the common hepatic duct and the cystic duct join. Its physiological role is to carry bile from the gallbladder and empty it into the upper part of the small intestine (the duodenum). The common bile duct is part of the biliary system.
Bile is a greenish-brown fluid that helps digest fats from our food intake. It is produced by the liver and stored and concentrated in the gallbladder until it is needed to help digest foods. When food enters the small intestine, bile travels through the common bile duct to reach the duodenum.
Gallstones are hard deposits that form inside the gallbladder when there is too much bilirubin or cholesterol in the bile. Although a person may have gallstones for many years without feeling any symptoms, gallstones can sometimes pass through the common bile duct, causing inflammation and severe pain. If a gallstone blocks the common bile duct, it can cause choledocholithiasis. Symptoms of choledocholithiasis include pain in the right side of the abdomen (biliary colic), jaundice, and fever. Choledocholithiasis can be life-threatening if not diagnosed and treated immediately.
---------------
Bile (from latin bilis), or gall, is a dark-green-to-yellowish-brown fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver (liver bile) and stored and concentrated in the gallbladder.
Understanding those emailed or printed results we get after our rabbit’s lab test can be difficult. I hope that the following explanations of two commonly‐ordered tests will help readers interpret their rabbit’s test results.
Printed results of the tests may be presented in graphical or numerical form. They usually include the test name and/or abbreviation, results, and the low and high ends of the normal range for that test.
Results that fall outside the normal range may be noted in some way. It is important to compare the results to the range provided by the laboratory rather than ranges published in texts or online as different methodologies used for the test will result in slightly different ranges.
Rarely, errors in taking, handling or analyzing the sample will cause erroneous results, particularly if the sample is not stored correctly or is not analyzed soon enough after taking it. If you have concerns about the validity of a test result discuss it with your vet. In some cases a new test may be warranted.
Haematology. In a CBC, or complete blood cell count, the amounts of the different kinds of blood cells present are tested.
Red blood cell (RBC or erythrocyte) count: Male rabbits and older rabbits tend to have higher counts than female and younger rabbits. Dehydration and stress from cold temperatures can cause high RBC counts. High counts of nucleated RBCs can be a sign of a bacterial infection; a very high count of nucleated RBCs can be a sign of a bad flea infestation or internal bleeding.
Slightly elevated counts of nucleated RBCs are not an abnormal finding in rabbits. The HCT (Hct, haematocrit) is a test in which the percent of red blood cells is calculated. A low value may be a sign of anemia. Hb, or hemoglobin concentration, can be used to help diagnose anaemia (low Hb) and its origin. Female rabbits tend to have much lower HB and Hct than males. Rabbits that get a lot of exercise may have elevated RBC, HB, and Hct values.
Platelets: High counts may be associated with iron‐deficiency anaemia and chronic bleeding. Cold stress can also cause elevated platelet values, as may drugs such as glucocorticoids and epinephrine.
Low levels may be a sign of a severe allergic reaction, massive bleeding, aplastic anaemia, and systemic bacterial or fungal infections. Low values can also be caused by storing the sample for too long before it is analyzed.
White blood cells (WBC, leukocytes): White blood cell counts vary depending upon the age, sex, breed and season of the year.
WBC counts may include counts for specific types, such as monocytes, lymphocytes, neutrophils/heterophils and basophils.
In rabbits it is often the proportion of the differing kinds rather than the total WBC count that helps determine the presence of an infectious disease. The proportion of neutrophils to lymphocytes should be 1:1; in a rabbit with an acute infection the proportion will often be nearer 2:1.
A high value for monocytes can be a sign of chronic infection and a high value for eosinophils and/or basophils can be a sign of a parasitical infection.
Serum/blood chemistry. The focus on these tests is on parameters of blood other than cell counts.
Serum glucose: Although high glucose can be a sign of kidney disease, it is often caused by stress, including the stress of the trip to the vet and having blood drawn. High glucose values can also occur in rabbits with acute intestinal obstruction, hepatic lipidosis, hyperthermia, and shock.
Some drugs can also cause elevated glucose levels, as can diabetes, but diabetes is extremely rare in rabbits. Low glucose levels can be caused by anorexia, digestive tract problems, liver disease, and septicaemia.
BUN (blood urea nitrogen): A key test used to assess kidney function. Urea levels depend upon a wide variety of factors, including the time of day, the amount of protein in the diet and how hydrated the rabbit is. Slightly high values are not uncommon in healthy rabbits.
High values may indicate there is some kind of kidney disease. Elevated values can also be a sign of encephalitozoonosis (EC). Low levels may be caused by anabolic steroids or liver damage.
Rabbits on corticosteroids, tetracycline, or aminoglycosides may have elevated levels; rabbits on chloramphenicol can have either low or high levels.
Creatinine: High values are often a sign of severe kidney or muscle damage. This test is less influenced by external factors than the BUN. However, levels may be high in rabbits that have gone a few hours without drinking water. A disadvantage of this test is that it does not show high levels until there has been substantial loss of kidney function (excepting temporarily high levels caused by dehydration, which do not involve such loss of function).
Cholesterol and triglycerides: To obtain accurate values for cholesterol the animal must be fasting. Since it is unsafe to fast rabbits for more than a couple of hours, not to mention that it is essentially impossible to fast most rabbits because of consumption of cecotrophs, results from this test should be considered only in conjunction with other tests.
High cholesterol values can be caused by obesity, a diet high in fats, pancreatitis and chronic kidney failure. Values also be high if the rabbit is not eating enough, but this is a sign of advanced hepatic lipidosis and has a poor prognosis. High triglyceride levels may be a sign of chronic kidney failure.
Calcium and phosphorus: Calcium levels are primarily influenced by the calcium content of the diet. High blood calcium levels in conjunction with clear urine (showing it is not being excreted as it should) are a sign of kidney failure.
Low calcium levels are rare but can occur in rabbits with poor nutrition. High phosphorus levels can be a sign of chronic kidney failure or soft tissue trauma.
Serum protein: Total protein levels may be high in rabbits that are dehydrated, whether from gastrointestinal hypomotility (stasis) or other reasons. Low levels can be caused by malnutrition or liver disease. Low levels of albumin (a specific protein) can be a sign of a heavy infestation of parasites, and high levels are a sign of advanced liver disease.
Bilirubin: High serum bilirubin levels in young rabbits are often caused by hepatic coccidiosis; in older rabbits they are more likely to be caused by an obstruction of the bile duct by neoplasia (cancer) or an abscess. AP (ALP, alkaline phosphatase): The normal range for this test is wide and varies with age (young rabbits have higher levels) and breed. A high value may be a sign of diseases affecting liver function such as hepatic coccidiosis, liver abscesses, and neoplasia.
ALT (alanine aminotransferase), also called GPT and SGPT: Another test that helps the vet assess whether there has been any liver damage. Mildly high levels may be found in rabbits that appear healthy and it is thought they may be caused by low concentrations of toxins such as aflatoxins in food or compounds in wood‐based litters.
High levels may be a sign of hepatic lipidosis or liver damage from hepatic coccidiosis.
AST (aspartate aminotransferase), formerly called SGOT: High values in conjunction with high ALT, AP, or protein may be a sign of liver damage. High levels may also be caused by the rabbit struggling during collection of the sample.
Urinalysis The urinalysis is another lab test that is ordered fairly frequently. More so than in blood work the normal value is often “negative,” or the absence of the tested‐for compound.
Protein: The normal finding is negative to trace amounts. High amounts can be a result of kidney damage/disease. High levels can also be caused by dehydration, strenuous exercise or stress, and for this reason protein is best looked at in conjunction with the specific gravity and the ratio of protein to creatinine. Dilute urine with a high protein value is more likely to be a sign of kidney damage/disease than concentrated urine with a similar protein value. Low protein levels can be a sign of malnutrition. SG (specific gravity): An SG level at the lower end of the normal range when combined with high creatinine and BUN is a sign of poor kidney function. pH: Normal rabbit urine has a high pH (7.5‐9). Lower pH can be caused by high‐protein diets, severe anorexia, and fever. Glucose: The normal finding for glucose is negative, although trace amounts may be found in healthy rabbits. Higher amounts can be caused by stress, including pain or any experience which is frightening to the rabbit. Ketones: The normal finding is negative. The presence of ketones indicates starvation or severe anorexia. Ketones may be seen in rabbits with severe dental disease that prevents them from eating or in rabbits on hay‐only diets that have severely impacted cecums. Rarely, ketones in the urine may be caused by diabetes mellitus. Bilirubin: High levels of bilirubin in rabbit urine are unusual but elevated levels may be caused by poisoning from aflatoxins in contaminated food, hepatic coccidiosis, or neoplasia.
Haematuria: Normally there is no blood present in rabbit urine. A positive result may be caused by inflammation and/or a urinary tract infection, crystals, or, less often, neoplasia. Sediment: Calcium carbonate sediment is a normal finding in rabbit urine. Other crystals can be caused by drugs the rabbit is taking, and struvite crystals can be a sign of bacterial infection. Urobilinogen: The finding for a healthy rabbit is negative. High levels may be caused by liver damage or drugs such as sulfonamides; low levels can be caused by long exposure to light. Nitrate and nitrite: Urine normally contains nitrates, but some bacteria convert nitrate to nitrite. The normal result for nitrite is negative; a positive result is caused by bacteria in the urine. However, not all bacteria are able to convert nitrates to nitrite, so a negative result does not mean a UTI is not present.
I set out at 7.30 am to walk in a new area - the strip alongside the long drainage canal. Many small swifts were seen. Usual mynahs. A couple of pink-necked pigeons fluttered above me. One stayed on the tree for me to take photos (Image 1).
Later, as I drove back, another one landed on a tree outside a house. I snapped a picture through the windscreen (Image 2). A few of such pigeons have been seen by me. It is difficult to differentiate one from another.
The lady was worried as this rabbit became lethargic, with her coat "untidy". She still has appetite. Examination showed urine-stained back area and below the hind limbs.
"Urine scalding" of the yellowed areas," I said. "The urine burns the skin, making it more itchy."
"What's the cause of this urine scalding?" the owner asked.
"It would be urinary tract infection, with the rabbit being unable to control her urination. So the urine stained her back area and the back legs!"
Treatment
Bathing and grooming by brushing and clipping off the urine-stained hairs.
