Hepatoblastoma is the most common primary liver tumour in children. Complete surgical removal is the treatment of choice for cure; however, in most cases the tumour is unresectable because of its extensive hepatic involvement. Nineteen pediatric cases (11 boys, 8 girls) with ages ranging from three months to 17 years were referred for management to our clinic from 1982 until 2000. All but three suffered from abdominal distention. The other frequent complaints were abdominal mass, anorexia, fatigue, abdominal pain and fever. Physical examination revealed enlarged liver in all patients. In addition to laboratory studies, they were pre-operatively examined by ultrasonography and, in recent cases, computed tomography was also used. Serum alpha-fetoprotein levels were found to be elevated in all patients. In thirteen cases, hepatic resections (10 lobectomies, 2 trisegmentectomies, 1 segmentectomy) were performed. In six children only liver biopsies could be done because of the huge tumour size. However, in three of them the tumours were excised at the second laparotomy, but only one patient survived. All of the patients - except two who were lost in the early postoperative period - received chemotherapy whether the tumour was excised or biopsied. In this series the mortality rate was found to be very high (91%) in the 1980s, and more reasonable (50%) in the 1990s, with an overall mortality rate of 73 per cent. This result might be explained with late referral and advanced stage at diagnosis. In addition, we speculate that a combination of improved chemotherapy and technical advances in anesthesia and hepatic resection caused the obvious differences in the survival rates between the two periods.

This report describes a case of nonfatal idiopathic splenic haematoma and pancytopenia in a female ass, a condition that has not been previously reported in this species. A 12-year-old female ass weighing 225 kg was presented with signs of anorexia, depression and prominent abdominal distension. At the onset of clinical signs there was evidence of anaemia, leucopenia and thrombocytopenia. A large mass was palpated per rectum. The mass was confluent with the spleen and extended across the entire width of the abdomen. Percutaneous transabdominal ultrasonography and laparoscopy under general anaesthesia confirmed the diagnosis of splenic haematoma. The ass was treated initially with intravenous polyionic fluids; vitamins, trace elements and aminoacids; clanobutin; and penicillin and gentamicin, and was transfused with whole blood. After 5 days of hospitalisation the ass appeared brighter, and after 10 days the animal was discharged to recuperate at pasture. Six months later the animal's demeanour and appetite had improved. Repeat ultrasonographic examination showed persistence of the mass, but its thickness had decreased by 2 to 3 cm. A small mineralised area suggesting organisation of the haematoma was also detected. The haematological parameters had returned to normal values and the ass was clinically normal.

Allopregnanolone, a neurosteroid acting as a potent anxiolytic agonist of the gamma-aminobutyric acid A receptor, has been shown in animal models to modify its concentrations at central and peripheral levels according to the estrous cycle. Moreover, it modulates behavioral and biochemical responses to acute and chronic stress, anxiety, depression, aggressiveness, convulsions, anesthesia, sleep, memory, pain and feeding. These observations suggest that fluctuations of allopregnanolone might be involved in the development, course and prognosis of some mental disorders in humans. This has been hypothesized for depressive disorders, premenstrual dysphoria, anorexia and bulimia nervosa and Alzheimer's disease, where increased, decreased or dysregulated secretion of the main neurosteroids and their metabolites has been observed. Women show a marked gender-related sensitivity to disadaptive disorders. In addition to the well-studied role of sex steroids in modulating mood and behavior, a putative involvement of neurosteroid fluctuations, and in particular of allopregnanolone, has recently been hypothesized. In fact, several paraphysiological events and various disadaptive disorders in women are associated with modifications of circulating levels of this neurosteroid that might associated with a certain vulnerability to an altered adaptation to stressful life events.

In the present work the effect of intramuscular administration of 30.000, 50.000 and 100.000 IU of vitamin A palmitate daily for seven days, respectively, on the liver enzyme activity in 45 white male Wistar rats, aged 12 weeks and weighing 180-200 g, have been studied. The group control was integrated by 15 healthy rats with similar characteristics (strain, gender, age and weight) to treated animals. Food and water consumption and body weights were recorded at the end of the experimental period. Rats were observed for clinical signs of toxicity. At the end of the study, rats were sacrificed under ether anesthesia. Liver samples were taken for the determination of enzyme activity. Administration of excess of vitamin A produced a significant (p < 0.05) increase in the content of liver vitamin A, determined diverse and variable clinical signs (such as, anorexia, loss of body weight, alopecia, conjunctivitis, external and internal hemorrhages, skin abnormalities and death) and increased (p < 0.05) the activity of the following enzymes: alanine aminotransferase, aspartate aminotransferase, acid maltase (acid alpha-1,4-glucosidase), acid proteases, lactate dehydrogenase and alkaline phosphatase while glucose-6-phosphatase, glycogen phosphorylase, alpha-amylase, cholinesterase and arginase decreased (p < 0.05) as compared with untreated controls. These changes depend on the doses given of vitamin A. In conclusion, our results provide evidence that short-term administration of high doses of vitamin A determined diverse and variable clinical signs and produces a marked alteration of activity of liver enzymes.

A 16-yr-old, captive-born, female California sea lion (Zalophus californianus) was evaluated for intermittent lethargy, partial anorexia, and polydipsia of 2 wk duration. The animal was immobilized for physical examination. It was in thin body condition, with multifocal mucosal ulcerations over the caudal and ventral tongue. Blood was collected for hematology, serum chemistry, and leptospirosis serology. Serum chemistry revealed severe azotemia, mild hyperglycemia, and severe hyperphosphatemia. The animal went into cardiac arrest during recovery from anesthesia and died. On histopathology, abundant amorphous, finely fibrillar, eosinophilic material was deposited in the kidneys, and smaller amounts of the same material were found in the splenic and pancreatic vessels; these findings are consistent with systemic secondary amyloidosis. The animal also had chronic nephritis, which, coupled with renal amyloidosis, resulted in renal failure and death. Systemic amyloidosis should be considered as an additional differential diagnosis for renal failure in California sea lions.

A 38-yr-old orangutan (Pongo pygmaeus pygmaeus) presented with chronic lethargy and difficulty in locomotion that progressed to weakness, anorexia, and permanent dorsal and/or lateral recumbency. The orangutan was immobilized with ketamine. Abdominal ultrasonography revealed a mass in the caudal portion of the abdomen. Exploratory surgery was performed, but the mass could not be resected. Instead, the mass was drained and omentalized in an attempt to establish continuous drainage after surgery. The only complication was a wound infection that was treated locally with a disinfectant and installation of a drain that was changed every 2 days under anesthesia. Omentalization was successful in providing continuous fluid drainage for this retroperitoneal abscess and required minimal postoperative handling of the animal.

We present a case report of a 14-month-old girl who ingested a moth cocoon, which resulted in dramatic symptoms of irritability, drooling, and anorexia. Direct laryngoscopy, bronchoscopy, and esophagoscopy under general anesthesia revealed copious, tenaciously adherent, barbed hairs embedded in her tongue and buccal mucosa. Removal of the hairs with irrigation, suction, and brushing was unsuccessful and was eventually abandoned. In the following 48 hours, the girl recovered uneventfully with supportive care. The hairs were subsequently identified as coming from the hickory tussock moth (Lepidoptera: Arctiidae: Lophocampa caryae), which is ubiquitously distributed throughout much of North America. This is the first detailed case report of ingestion of an L caryae cocoon.

In veterinary medicine, serum creatine-kinase (CK) activity is mostly used to assess skeletal muscle damage. This retrospective study aimed to evaluate the prevalence of increased CK activity in a large, ill-cat population and to characterise associated diseases, clinical and laboratory findings and its prognostic value. Cats with a complete serum biochemistry analysis were consecutively enrolled, divided into two CK activity-based groups (within and above reference interval) and compared. The study included 601 cats. Median serum CK was 402 U/l (range 16-506870). Increased CK (>250 U/l) was observed in 364 (60%) cats, and>30-fold its upper reference limit in 43 (7%). Cats with increased CK had greater (P < or = 0.05) body weight, and were more likely to have a history of collapse, dyspnoea, abnormal lung sounds, cyanosis, shock and paraplegia, higher median serum alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities and total bilirubin and triglyceride concentrations, but lower, median total protein, albumin, globulin and cholesterol concentrations and proportion of anorexia than cats with normal CK. Cardiac diseases, trauma, bite wounds, systemic bacterial infections, prior anaesthesia and intramuscular injections were more common (P < or = 0.05) in cats with increased compared to normal CK activity. The hospitalisation period was longer (P=0.007) and treatment cost and mortality were higher (P<0.005) in cats with increased CK activity. However, CK activity was an inaccurate outcome predictor (area under the receiver operator characteristics curve 0.58). Increased CK activity is very common in ill cats.

A 3-year-old girl presented with a hemorrhagic conjunctival lesion in the right eye. The medical history revealed premature cessation of breast feeding, intolerance to the ingestion of baby foods, anorexia, and abdominal distention. Prior to her referral, endoscopic small intestinal biopsy had been carried out under general anesthesia with a possible diagnosis of Celiac Disease (CD). Her parents did not want their child to undergo general anesthesia for the second time for the excisional biopsy. We decided to follow the patient until all systemic investigations were concluded. In evaluation, the case was diagnosed with CD and the conjunctival tumor showed complete regression during gluten-free dietary treatment. The clinical fleshy appearance of the lesion with spider-like vascular extensions and subconjunctival hemorrhagic spots, possible association with an acquired immune system dysfunction due to CD, and spontaneous regression by a gluten-free diet led us to make a presumed diagnosis of conjunctival Kaposi sarcoma.

Japanese macaques bred indoor for laboratory use often show chronic anorexia and intermittent vomiting. In some of our macaques gastric air was observed on physical examination, and we suspected abnormality of gastric motility. We therefore performed contrast radiographic examinations of the gastrointestinal tract without anesthesia of 8 macaques with gastrointestinal symptoms and 9 asymptomatic controls from the same laboratory. Changes of abdominal radiography over time were observed following oral administration of contrast medium. In all control animals, contrast medium had completely passed from the stomach within 150 min after administration. However, all animals with gastrointestinal symptoms retained some contrast medium in the stomach. Gastric emptying time of contrast medium was associated with excessive gastric air in Japanese macaques; therefore, gastric emptying time seems to be associated with decreased gastric motility.
