Total Body Irradiation For The Treatment Of Lymphoma In A Guinea Pig (Cavia porcellus)
A five-year-old intact male guinea pig was evaluated for a 2-week history of “red eyes”. Sniffling and lethargy had been noticed for several days as well.Physical examination findings included increased expiratory effort and bilateral chemosis. Several peripheral lymph nodes were markedly enlarged. Fine needle aspiration of the enlarged lymph nodes was consistent with ly mphoma.The first total body irradiation with 1 Gray (Gy) resulted in a good response as evidenced by a decrease in lymphocytes and reduced sizes of the enlarged peripheral lymph nodes.

Squamous cell carcinoma in chinchillas: a review of three cases
The authors describe three cases of squamous cell carcinoma in chinchillas. The neoplasms were diagnosed by histological examination. All three animals were older than 15 years and had ulcerative skin masses involving one or more limbs. Automutilation was present in all three cases, and the owners noticed the masses when they were already of significant size (2 –5 cm in diameter). All three animals were euthanized within two months after the first presentation. Papillomavirus PCR assay were performed on all three tumors, but didn't find papillomavirus DNA in the samples.

Use of a Gastrostomy and Jejunostomy Tube for Management of Gastric Distention Following Pyloric Outflow Obstruction in a Ferret (Mustela putorius furo)
An eight month old spayed female ferret (Mustela putorius furo) was presented for evaluation of persistent, severe gastric distention following gastrotomy to retrieve several foreign bodies. A structural cause of gastric outflow obstruction was not identified ultrasonographically or surgically. A 14fr gastrostomy and an 8fr jejunostomy tube were used to facilitate medical management of severe gastric stasis and to allow enteral nutrition. The ferret tolerated the feeding tubes well and recovered completely following intensive medical therapy. (Source: Journal of Exotic Pet Medicine)

Comparative efficacy of different antidotes against experimental nitrate intoxication in rabbits
The antidotal efficacy of aqueous garlic extract, methylene blue, and velenium (Vitamin E+sodium selenite) was compared against experimental nitrate intoxication in rabbits. Forty-two, albino rabbits of identical age, gender and body weight were randomly divided into 7 groups (A to G) and subjected to experimental treatments for a period of 40 days. Rabbits of group A were offered only normal feed and served as negative control, while, rabbits of group B constituted the positive control group and received feed supplemented with sodium nitrate at 400 mg/kg body weight.

Mesenteric Root and Cecal Torsion in a Domestic Rabbit (Oryctolagus cuniculus)
A 4.5-year-old female spayed Rex rabbit (Oryctolagus cuniculus) was presented as an emergency case for hyporexia, pigmenturia, and abnormal feces. The rabbit had been treated for intermittent hyporexia with outpatient medical management and over the next two months demonstrated intermittent signs of gastrointestinal stasis, which were only partially responsive to aggressive medical management. Serial radiographs demonstrated persistent gas within the cecum as well as left-sided, cranial displacement of the cecum. (Source: Journal of Exotic Pet Medicine)

Cleft palate in a chinchilla (Chinchilla lanigera)
A 5-month-old female chinchilla (Chinchilla lanigera) was evaluated for failure to thrive, difficulty drinking, and respiratory signs. Physical examination demonstrated a thin body condition score, purulent nasal and ocular discharge, and an abnormal facial appearance. Endoscope-guided oral examination and computed tomography (CT) scan demonstrated a cleft soft palate, absent nasal turbinates, and bilateral otitis media. The animal was euthanized and necropsy confirmed the diagnosis of palatoschisis (cleft palate) of the soft palate. (Source: Journal of Exotic Pet Medicine)

Antinociceptive Efficacy and Safety of Subcutaneous Tramadol in Chinchillas (Chinchilla lanigera)
Tramadol has been demonstrated to provide analgesia in rodents (e.g., rats, mice) and has been increasingly used in other small companion mammals for treatment of moderate to severe pain. Currently no evidence is available that supports the use of tramadol as an effective analgesic in chinchillas. The purpose of this study was to evaluate the antinociceptive efficacy and safety of subcutaneously administered tramadol in chinchillas. Initial dose-escalation studies were performed to determine if dose-dependent adverse effects occur in chinchillas. (Source: Journal of Exotic Pet Medicine)

Literature Review of Radiographic Measurements of Internal Organs in Psittaciformes
This review article contains the published measurements and ratios of the different coelomic organs in birds including the heart, proventriculus, and liver. Radiographic examination of birds is becoming very important in the daily diagnostic assessment of patients presented to veterinary hosptials. When a veterinarian is treating birds, it is crucial to have a broad theoretical knowledge of the subject as well as sufficient practical experience. However, there may be some help for the less experienced veterinarian as they assess their avian patients with primary diagnostic options. (Source: Journal of Exotic Pet Medicine)

Scrotal Vesicle Seminal Hernia in an Intact Male Domestic Guinea Pig
A nine-month-old intact male guinea pig was presented with a 2-week history of progressive swelling involving the right scrotal sac. Physical examination revealed a soft mass involving the caudal aspect of the right scrotal sac. Subsequent radiographic evaluation of the affected area confirmed a soft tissue subcutaneous swelling. Ultrasonography revealed a hyperechogenic homogenous structure with normal hemodynamic pattern within the right scrotum, and an enlarged right inguinal ring measuring 8-9 mm.

Semen-Matrix Calculi in a Juvenile Chinchilla (Chinchilla lanigera)
A 10-month-old, intact male chinchilla (Chinchilla lanigera) was diagnosed with urolithiasis, unilateral hydroureter, and hydronephrosis secondary to ureteral obstruction confirmed by radiography and ultrasonography. Nephrectomy and cystotomy were performed, and the urolith was suspected to be a semen-matrix calculus (mineralized copulatory plug) based on the discovery of sperm within the renal pelvis of the nephrectomized kidney on histopathology; this was later confirmed through a post-mortem examination.

Tetracycline Resistance of Enterobacteriaceae Isolated From Feces of Synanthropic Birds
Tetracycline is a broad-spectrum antibiotic which is commonly used in humans and animals for treatment of bacterial infections. Therefore, tetracycline-resistant Enterobacteriaceae species found in the nature, humans, and animals are usually considered a serious health concern. The feces of birds that live with humans may be a source for of these antibiotic resistant bacteria. For this reason, presence of tetracycline-resistant Enterobacteriaceae in bird droppings collected from 18 different breeders and pet shops fed in Istanbul was investigated by cultural and molecular methods in terms of the presence of that a/b gene. ...

Diagnostic Challenge
A three-year-old male green iguana (Iguana iguana) weighing 1.01 kg was presented with a one-month history of left forelimb swelling, weight loss and dysorexia (Fig. 1A). The reptile had been bred in captivity and was kept with a female of the same species that was considered in good health. The owner described the patient's enclosure as a terrarium maintained with a diurnal temperature of 28 - 30°C (82 - 86°F) under the basking spot, without any UVb source. The iguana's diet consisted of various fruits and vegetables provided daily, without any known calcium supplementation. (Source: Journal of Exotic Pet Medicine)

Diagnostic Challenge
A 3-year-old female chinchilla (Chinchilla lanigera) was presented for a mass located at the vertex of the head and appeared after a fall in the cage the day before. The husbandry practices and diet provided to the patient were appropriate. The chinchilla had no medical history and appeared healthy. A close examination of the animal's head revealed a soft, painless mass approximately 3 centimeters in diameter (Fig. 1). The mass appeared to be filled with air suggesting subcutaneous emphysema. The chinchilla was bright and alert and had mild dyspnea associated with the upper respiratory tract with audible wheezing but no ...

Uterine Leiomyoma, Fibroma, and Hemangioma in two Chinchillas (Chinchilla laniger)
Two female chinchillas were presented with reduced appetite and production of small fecal pellets. Physical examination of both chinchillas revealed a reduced vaginal membrane, bloody vaginal discharge, and a palpable mass in the caudal abdomen. Radiographic images revealed soft tissue masses in the caudal abdomen of both animals. In addition, the first case was examined by ultrasound, which identified two cystic masses, both originating from one of the uteri. Both chinchillas were euthanized due to progressive clinical deterioration with both animals undergoing postmortem examinations. (Source: Journal of Exotic Pet Medicine)

Effects of Natural Ultraviolet Radiation On 25-Hydroxyvitamin D3 Concentrations in Female Guinea Pigs (Cavia Porcellus)
Vertebrates have 2 methods of acquiring vitamin D: through the diet and/or secondary to exposure to ultraviolet B (UVB) radiation. Although some species (e.g., dogs) can only acquire vitamin D through their diet, many others also utilize UVB radiation to generate vitamin D. Prior to their extirpation, guinea pigs were naturally exposed to varying levels of sunlight (UVB) in their native habitat; however, in captivity we do not routinely recommend UVB radiation for these animals. Recently, it has been shown that captive guinea pigs can synthesize 25-hydroxyvitamin D (25-OHD3) after exposure to UVB lightbulbs. (Source: Journ...
