A previously stranded 30-kg female green turtle (Chelonia mydas) was referred to the Veterinary Medical Teaching Hospital at the University of Florida following a 2-mo history of anorexia, intermittent regurgitation, decreased fecal production, and positive buoyancy of the right side. Radiographs confirmed gaseous distension of bowel loops suggestive of intestinal obstruction. The coelom was surgically approached through a plastron osteotomy, and a 540 degrees volvulus of the small intestine was identified and derotated. An intestinal stricture was present at the site of the volvulus, and segments of bowel orad to the stricture were greatly distended. Following resection of abnormal bowel, the osteotomy was stabilized using self-tapping screws and figure-eight wire, and the defect was sealed with fiberglass cloth and fast-drying epoxy resin. A leiomyoma associated with the focal stricture was identified by histology. Appetite and defecation returned to normal. Six months after surgery, the turtle had regained normal buoyancy and showed no further clinical signs of gastrointestinal obstruction.

Between April 1998 and June 1999, 8 palm vipers (Bothriechis marchi) were diagnosed with a disease similar to inclusion body disease (IBD) of boids. Six palm vipers were captive bred, and 2 were wild caught. All of the vipers were adults at the time of death. Three palm vipers were found dead with no premonitory clinical signs, and 5 had anorexia plus possibly 1 of the following clinical signs: regurgitation, paresis, and dehydration. Histologically, all snakes had intracytoplasmic, round to oval, single to multiple eosinophilic inclusion bodies in hepatocytes and renal tubular epithelial cells. Inclusion bodies were distributed among other organs with varying frequency. Common concurrent histologic lesions were urate nephrosis, septic thrombi, and hepatocellular degeneration. Ultrastructurally, inclusions had features similar to inclusions in boid snakes with IBD.

The nematode Spirocerca lupi is a parasite of dogs with beetles of several species serving as intermediate hosts. The medical records of 50 dogs diagnosed with spirocercosis at the Hebrew University Veterinary Teaching Hospital (HUVTH) in Israel during 1991-1999 were retrospectively reviewed and compared to a control group (n=100). There was a seven-fold increase in the annual number of dogs diagnosed with spirocercosis during these years while the hospital caseload increased by 80%, indicating an emerging outbreak of this infection. Dogs from the greater Tel Aviv area were at the highest risk of being diagnosed with spirocercosis with 74% of the cases originating from this region compared to only 17% of the controls. The disease appeared to have a primarily urban pattern of distribution with a significantly higher percentage (P=0.025) of dogs from cities versus rural areas, as compared to the control group. Sixty-two percent of the cases were diagnosed during the colder months of December through April. The median age of infected dogs was 5 years, with dogs 1 year old or younger at the lowest risk of being diagnosed with spirocercosis. Large breeds were at a higher risk of infection in comparison to small breeds and the Labrador Retriever was significantly over represented (P=0.027) in the study group compared to the control population. The most common signs were vomiting or regurgitation (60%), pyrexia (24%), weakness (22%), respiratory abnormalities (20%), anorexia (18%), melena (18%) and paraparesis (14%). A caudal esophageal mass was identified by radiography in 53% of the dogs and spondylitis of the thoracic vertebrae in 33%. Fecal flotation was positive for S. lupi eggs in 80% of the dogs, and endoscopy was found to be the most sensitive diagnostic procedure and allowed diagnosis in 100% of the examined dogs. Fifty-three percent of the dogs were anemic and creatine kinase (CK) activities were elevated in 54%. Necropsy of 14 dogs revealed esophageal or gastric granulomas in 13 dogs, and an esophageal osteosarcoma in a single animal. Aortic aneurysms were found in six (43%) dogs. Out of 24, 15 dogs (63%) for which follow-up information was available died or were euthanized within 1 month of admission. The case-fatality rate decreased toward the end of the study period when improved therapy with avermectins became available.

Seventeen client-owned dogs diagnosed with spirocercosis-associated esophageal sarcomas were retrospectively reviewed. The most common clinical signs noticed were vomiting and/or regurgitation (94%), lethargy and depression (59%), pyrexia and anorexia (41% each). Leukocytosis (82%) and microcytic hypochromic anemia (30%) were the most common hematological abnormalities. Caudal thoracic masses were demonstrated on survey radiographs of 13/15 of the dogs and thoracic spondylitis was detected in 12/15 dogs. Spirocerca lupi eggs were detected in 2/8 patients and worms were demonstrated on 1/11 at necropsy. Ten cases underwent surgical attempt to remove the tumors. In six of them partial esophagectomy (PE) was performed and all of them survived the immediate postoperative hospitalization. Five of the cases that underwent PE also received chemotherapy after surgery (doxorubicin (Adriamycin, Upjohn)) with an average survival time of 267 days. The histopathological results of the esophageal tumors were osteosarcoma (9), fibrosarcoma (5) and undifferentiated sarcoma (1). In areas endemic to spirocercosis, regurgitation or vomiting in dogs and microcytic hypochromic anemia and neutrophilia warrant ruling out esophageal sarcomas. Proper surgical treatment could prolong the dogs' lifespan for months, and improve their quality of life.

Eastern equine encephalitis (EEE) was diagnosed in a flock of African penguins. Diagnosis was based on history and clinical signs and confirmed via serologic testing, virus isolation, reverse transcriptase-polymerase chain reaction (RT-PCR) assay, and histologic examination. Clinical signs in penguins included anorexia, behavior changes, depression, regurgitation, ataxia, recumbency, and seizures, and some penguins did not have any clinical signs. Mean +/- SD number of days that affected penguins had clinical signs was 12 +/- 5 days. Abnormalities initially detected on CBC included heterophilic leukocytosis and anemia; lymphocytosis and monocytosis were detected later. Plasma biochemical abnormalities included high activities of aspartate amino-transferase and creatine kinase, hyponatremia, hypochloremia, hyperglycemia, and high concentrations of globulin, triglycerides, and cholesterol. Mean +/- SD number of days required for resolution of CBC and plasma biochemical abnormalities was 67 +/- 24 days after the onset of clinical signs. Treatment consisted of supportive therapy. All penguins survived with the exception of one that was euthanatized; histopathologic findings were consistent with encephalitis. Results of RT-PCR assays performed on tissue from the right cerebrum of the penguin that was euthanatized were positive for EEE viral RNA. An inability to isolate virus several weeks after illness suggested successful viral clearance in recovered penguins. To the authors' knowledge, EEE infection in any penguin species has not been reported.

Children and adolescents with symptomatic gastroesophageal reflux disease (GERD) and erosive esophagitis (EE) of grade >/=2 (n=45) or nonerosive esophagitis (NEE) (n=45) were assessed to determine the relationship between presenting symptoms, esophagitis severity, and patient age. Overall, regurgitation/vomiting, abdominal pain, and cough were the most frequent symptoms. The prevalence and severity of anorexia/feed refusal was significantly greater in EE versus NEE children; this symptom was also significantly more prevalent in younger (1-5 years) children (both NEE and EE groups) compared to older children. Cough was significantly less severe in NEE adolescents than in younger children. Cough, anorexia/feed refusal, and regurgitation/vomiting were more severe and heartburn was less severe in EE children aged 1-5 years compared with older patients. In conclusion, GERD in children manifests differently than that in adults and symptoms vary with patient age. Symptoms were not predictive of presence or lack of mucosal damage.

Non-ulcer dyspepsia is a common clinical disorder characterised by reduced gastric motility. Safety concerns have restricted use of currently available prokinetic drugs. Itopride is a new safer prokinetic drug with dopamine D2 antagonism and acetylcholinesterase inhibitory actions. The ENGIP-II study was conducted to investigate the efficacy, and safety of itopride in patients of non-ulcer dyspepsia. There were significant reductions in upper abdominal pain, heartburn frequency, gastro-oesophageal regurgitation, nausea, bloating, early satiety after meals at day 3 only; whereas significant improvements were noted in belching, anorexia at day 6 and in vomiting at day 9. Thus, ENGIP-II study shows that itopride was well tolerated patients and appears to be the drug of choice in patients with non-ulcer dyspepsia.

Andrographolide, the 'King of bitters' requires high doses in the form of an extract (33.3%w/w) to be used as a hepatoprotectant. Since a large dose of this herb is known to cause gastric distress, vomiting, loss of appetite and nausea on regurgitation, it was thought of to convert the drug itself into a bitterless micropellet. The technique of ionotropic gelation of sodium alginate with calcium ions with subsequent drug entrapment was employed. The optimization of process parameters like the bore diameter of the needle, % concentration of sodium alginate, method of drying, drying time and temperature, time of contact of the micropellets in calcium chloride solution and concentration of calcium chloride to be used for the gelation were undertaken. The micropellets were finally prepared by adding 2.5%w/v of sodium alginate into a 2%w/v solution of calcium chloride solution using 20-guage flat tip needle and dried using a hot air oven at 60(o)C for 6 hrs. The so formed pellets were completely bitterless and released the andrographolide preferably away from the stomach. Pellets with varied drug: polymer ratio (1:2, 1:1 and 2:1) were prepared accordingly and analyzed for release kinetics. Release studies showed only about 15% release upto 4 hrs in pH 1.2 and pH 4.0 respectively and released the remaining in pH 7.4. The data obtained in the dissolution studies was fitted into various mathematic models defining kinetics of drug release like the zero-order rate equation, first-order rate equation, Hixson-crowell, 2/3rd rule, Korsemeyer-Peppas, Baker-lonsdale, Higuchi, Weibull, Ford and Hopfenberg Equation. The release kinetics of andrographolide from the alginate pellets was found to be best described by the korsemeyer-peppas equation which provided n values ranging from 1.0-1.47 with good linearity of the best-fit line (R(2)=0.9973). In conclusion, andrographolide can be easily converted to bitterless multiple unit dose oral delivery systems with good entrapment efficiency and a maximum release of 86% by utilizing the technique of ionotropic gelation.

Spirocerca lupi is a nematode infesting the canine oesophagus, where it induces the formation of a nodule that may transform into a malignant sarcoma. The current, retrospective study compared the clinical presentation, haematology, serum albumin and globulin and radiology of benign cases (n=31) and malignant cases (n=31) of spirocercosis. Dogs with spirocercosis-induced sarcoma were significantly older (6.4+/-1.91 years) than benign cases (4.93+/-2.87). In the malignant cases there were significantly (p=0.03) more sterilized females (10/31) and fewer intact males (4/31) compared to 2/31 and 13/31, respectively, in the benign cases. Hypertrophic osteopathy was observed in 38.7% of malignant cases and in none of the benign cases (p=0.0002). Common clinical signs included weight loss, regurgitation, anorexia, pyrexia (T>or=39.5 degrees ), respiratory complications and salivation but did not differ in prevalence between groups. On haematology, the malignant group had significantly (p<0.05) lower haematocrit (0.34+/-0.08 vs. 0.41+/-0.07) and higher white cell count (31.6+/-27.83 vs. 17.71+/-13.18 x 10(3)microl(-1)), mature neutrophil count (26.06+/-26.08 vs. 12.23+/-9.96 x 10(3)microl(-1)) and thrombocyte count (493.15+/-151.61 vs. 313.27+/-128.54 x 10(9)microl(-1)). There were no differences in the mean corpuscular volume and immature neutrophil count. On radiology, the mass length was not significantly different, but the height and the width of the malignant masses were significantly larger (62.59+/-15.15 mm and 73.93+/-20.94 mm) compared to the benign group (46.43+/-23.62 and 49.29+/-25.56, respectively). Spondylitis was more prevalent in the malignant group (67.86% vs. 38.46%, p=0.03). Examining secondary pulmonary changes revealed significantly higher prevalence of bronchial displacement in the malignant group (52% vs. 17%, p=0.008). Hypertrophic osteopathy appeared to be a very specific but relatively rare (poor sensitivity) marker of malignancy. Female gender, anaemia, leukocytosis, thrombocytosis, spondylitis and bronchial displacement are significantly more common in malignant cases, but appear in benign cases as well. However, if found together in a specific case, they should increase the index of suspicion for malignancy in a diagnosed spirocercosis case.

52 captive falcons out of 3,988 (1.3 %) raptors microscopically examined for intestinal parasites in the Middle East proved infested with hairworms (capillariid parasites). 26 of these (50 %) showed concurrent parasitoses. In the group of 26 falcons diagnosed with capillariosis as sole infestation (50 %) compatible clinical signs such as anorexia, weight loss, weakness, dyspnoea, regurgitation of food and blood, diarrhoea and dark tarry faeces, were recorded. These birds were treated intramuscularly with ivermectin at doses of 2 mg/kg. In fecal samples examined 10-15 days later, the eggs of capillariid parasites had disappeared, in association with complete clinical recovery.
