The risk of transmission of hepatitis C virus (HCV) infection is an important problem for the health care worker. HCV transmission by blood splashing into eyes is very rare. In a hemodialyses department, a 23-year-old female nurse splashed blood from a patient who was anti-HCV positive into her eyes. She washed her eyes with water immediately and reported to the infection control department. She had never used intravenous drugs nor received transfusions. At the time of exposure, there was no abnormality in her laboratory tests. Her anti-HCV and HCV-RNA tests produced negative results. She was followed up for anti-HCV and alanine aminotransferase activity. After 6 months, she presented with sore throat, nausea, vomiting, fatigue, and weight loss. She had icterus and hepatomegalia. In laboratory tests, alanine aminotransferase level was 504 U/L, aspartate aminotransferase level was 388 U/L, and anti-HCV and HCV-RNA tests produced positive findings. She was treated with interferon alfa-2a for a 1-year period. After treatment, an HCV-RNA test produced negative results and transaminase levels were normal. In conclusion, splashing blood from patients who are HCV positive into the face or eyes is a risk for health care workers. They should be educated to prevent a nosocomial acquisition of bloodborne infection and they should observe protective precautions.

This study was designed to evaluate possible organ and system disorders associated with experimentally induced levamisole poisoning in dogs. For this purpose, twelve clinically healthy dogs of different ages, sexes and breeds were used. They were divided into two equal groups (Group A and Group B) and given levamisole orally at a dose of 25 mg/kg of body weight daily for three days. The dogs in Group B were also injected with atropin sulphate (0.04 mg/kg of body weight) subcutaneously (sc) 1 hour after each administration of levamisole. Routine clinical examinations were made and some haematological, biochemical and blood gas parameters were established at various times after administration of levamisole. The dogs in Group A developed severe neurological signs, gastric haemorrhage, bloody vomiting, colic, anaemia and four dogs died. In Group B these signs were mild and only one dog died. Levamisole poisoning was characterised by a significant reduction in the total number of red blood cells (RBCs), concentration of haemoglobin (Hb) and packed cell volume (PCV), and by anaemia. Peripheral blood pH, actual bicarbonate of plasma (HCO3), actual base excess (BE), partial pressure of oxygen (pO2) and saturated oxygen (O2SAT) increased in both groups of animals and these dogs developed metabolic alkalosis 48 hours after the first administration of levamisole. The results of the study also show that levamisole poisoning in dogs causes a significant increase in the activity of serum alanine aminotransferase (ALT) and of alkaline phosphatase (AP) and in the concentration of urea in both Group A and Group B. In the study, atropin sulphate reduced the severity of the clinical signs and the number of deaths, but it was not alone sufficient to remedy levamisole poisoning in dogs.

Eight cases of feline pancreatic adenocarcinoma and two cases of pancreatic adenoma were reviewed. The adenomas were incidental findings. Most cats with adenocarcinomas had anorexia (75%) and vomiting (63%), while 38% had abdominal pain, a palpable abdominal mass, and/or jaundice. Diagnostic abnormalities included leukocytosis, hyperglycemia, increased alanine aminotransferase activity, poor serosal detail on abdominal radiography, and an abdominal mass effect on ultrasonography. The majority of cats with carcinomas had metastases (mostly to liver, lung, and small intestine), and all were euthanized or died within 7 days of diagnosis. Clinically, feline pancreatic carcinoma may be difficult to distinguish from feline pancreatitis.

Two of our patients experienced myotoxicity associated with colchicine administration. The first was a 54-year-old woman who was receiving dialysis and came to the emergency department with progressive generalized weakness and vomiting. She recently had taken colchicine for the treatment of gout. Physical examination revealed proximal muscle weakness and tenderness on palpation. Her creatine kinase (CK), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels were elevated at 7185, 563, and 541 U/L, respectively. Drug-induced myopathy was suspected and colchicine was discontinued. The patient was discharged after symptom resolution 1 week later. The second patient was an 83-year-old woman with chronic renal insufficiency who came to the hospital with anorexia, diarrhea, and inability to get out of bed due to progressive weakness. Her colchicine dosage recently had been increased for gout management. Physical examination revealed generalized muscle weakness and tenderness on palpation. Her CK, ALT, and AST levels were elevated at 1797, 147, and 172 U/L, respectively. Electromyographic results were consistent with colchicine myopathy. The patient was discharged with minimal residual muscle weakness 1 week after discontinuation of colchicine. A literature search identified 82 documented cases of colchicine-induced myotoxicity. Most patients had a history of proximal weakness and pain with elevated CK, ALT, and AST levels. Onset of symptoms generally occurred days to weeks after initial administration of colchicine at the usual dosage in patients with renal impairment or a change in underlying disease state in those receiving long-term therapy. Muscle toxicity was not necessarily accompanied by gastrointestinal symptoms. Concomitantly administered drugs often were cyclosporine or corticosteroids. Diagnosis may be confirmed by electromyography or muscle biopsy. Colchicine-induced myotoxicity is a rare adverse effect but is well described in the literature. Clinicians should recognize that renal impairment is the primary risk factor for development of colchicine-induced myotoxicity, and that dosage adjustment or alternative therapy may be required.

An 8-year-old, male domestic shorthair cat was referred to the Matthew J. Ryan Veterinary Hospital of the University of Pennsylvania with a 3-day history of lethargy, inappetance, hyperemic skin nodules, coughing, and vomiting. Laboratory results included nonregenerative anemia, lymphopenia, thrombocytopenia, hypoalbuminemia, hyponatremia, and increased alanine aminotransferase and aspartate aminotransferase activities. Cytology of the skin nodules revealed many spindle- to crescent-shaped protozoal organisms, with morphology consistent with Toxoplasma gondii or Neospora caninum. Gross necropsy, histopathologic, immunohistochemical, and transmission electron microscopic findings confirmed a systemic protozoal infection; however, the organism exhibited characteristics of both N caninum and T gondii. Diagnosis of a T gondii-like infection was based on internal structures of the organism and positive reaction to rabbit polyclonal antibodies to T gondii. Reports of toxoplasmic dermatitis are rare in the cat and dog, and this is the first reported diagnosis of T gondii-like protozoa in skin aspirates.

The patient was a 57-year-old woman presenting with jaundice as the chief complaint. She began vomiting on July 10, 2003. Jaundice was noted and admitted to our hospital for thorough testing. Tests on admission indicated severe hepatitis, based on: aspartate aminotransferase (AST), 1 076 IU/L; alanine aminotransferase (ALT), 1 400 IU/L; total bilirubin (TB), 20.9 mg/dL; and prothrombin time rate (PT%), 46.9%. Acute hepatitis A (HA) was diagnosed based on negative hepatitis B surface antigen and hepatitis C virus RNA and positive immunoglobulin (Ig) M HA antibody, but elevation of anti-nuclear antigen (X320) and IgG (3 112 mg/dL) led to suspicion of autoimmune hepatitis (AIH). Plasma exchange was performed for 3 d from July 17, and steroid pulse therapy was performed for 3 d starting on July 18, followed by oral steroid therapy. Liver biopsy was performed on August 5, and the results confirmed acute hepatitis and mild chronic inflammation. Levels of AST and ALT normalized, so dose of oral steroid was markedly reduced. Steroid therapy was terminated after 4 mo, as the patient had glaucoma. Starting 3 mo after cessation of steroid therapy, levels of AST and ALT began to increase again. Another liver biopsy was performed and AIH was diagnosed based on serum data and biopsy specimen. Oral steroid therapy was reinitiated. Levels of AST and ALT again normalized. The present case was thus considered to represent AIH triggered by acute HA.

Miltefosine (2.5 mg/kg/day for 28 days) was investigated for treatment of New World cutaneous leishmaniasis in Colombia and Guatemala. The data from a controlled study was remarkably similar to the data of a prior uncontrolled pilot study. In the controlled study, the per-protocol 6-month cure rate for Leishmania panamensis disease was 91% compared with a concomitant placebo cure rate of 38%. In Guatemala, the cure rate for L. braziliensis and L. mexicana disease was approximately 50% compared with approximately 20% for placebo. In both countries, nausea but not 'motion sickness' and vomiting but not diarrhoea were experienced by approximately 30% more miltefosine patients than placebo patients. Mild elevation of creatinine, but not of aspartate aminotransferase or alanine aminotransferase, was also more frequently seen in the miltefosine group than in the placebo group. Miltefosine was well tolerated, and as effective as historic values of antimony for treatment of L. panamensis disease.

This study summarizes the clinical and pathologic findings in 15 Labrador Retrievers with copper-associated chronic hepatitis (CACH). Our hypothesis was that this form of hepatitis is caused by a defect in hepatic copper metabolism, which most likely originates from a genetic defect. Affected Labradors consisted of 11 female and 4 male Labrador Retrievers. Eight family members of 2 of these patients were examined prospectively, as were 6 unrelated healthy Labrador Retrievers. All dogs were registered at the breed club. The average age at clinical presentation was 7 years (range, 2.5-10.5 years). All dogs were presented for anorexia, which was associated with vomiting in 8 patients. The diagnosis of CACH was based on histologic examination of liver biopsy specimens in all dogs, including semiquantitation of copper. A disproportionate increase in alanine aminotransferase (ALT) activity relative to alkaline phosphatase (ALP) activity, as well as the centrolobular localization of copper and the association of copper accumulation with hepatic lesions, suggested a primary copper storage disease rather than primary cholestatic liver disease causing copper accumulation. Mean hepatic copper concentration measured in related Labradors was 1,317 microg/g dry weight liver (range, 402-2,576 microg/g). Mean hepatic copper concentration of unrelated normal Labradors was 233 microg/g dry weight liver (range, 120-304 microg/g). Our findings support the hypothesis that a hereditary form of hepatitis occurs in Labrador retrievers and is caused by a defect in hepatic copper metabolism.

Seven icteric dogs were determined to have bile duct obstruction secondary to chronic pancreatitis. All dogs had histories of intermittent vomiting and diarrhea. Alkaline phosphatase and alanine aminotransferase activities and total bilirubin concentrations were markedly elevated. Diagnosis was based on exploratory laparotomy and histological examination. Each dog had a 3 to 10 cm mass in the body of the pancreas and obstruction of the common bile duct. Three dogs treated with pancreatectomy, gastrojejunostomy, and cholecystojejunostomy died within five weeks. Three dogs treated with conservative surgical procedures were alive at 8, 16, and 26 months postoperatively. One dog was euthanized because of suspected neoplasia. Hepatic enzyme activity and bilirubin levels decreased markedly in the surviving dogs. Histological examination of the pancreatic masses indicated chronic pancreatitis. Hepatic biopsies revealed evidence of cholestasis. Chronic pancreatitis should be included in the differential diagnoses of icterus, bile duct obstruction, and masses in the pancreas.

Rotavirus is one of the leading causes of acute gastroenteritis among children. While clinical complaints are generally intestinal including vomiting and diarrhea, there is evidence to suggest that disease outside the gastrointestinal tract occurs. This study examines the frequency of hepatic transaminase elevation in children with rotavirus gastroenteritis. Patients identified with rotavirus gastroenteritis by stool antigen testing between November 2005 and March 2006 had available serum analyzed for alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, total bilirubin, direct bilirubin, and creatinine phoshosphokinase (CPK). Chart review was conducted to identify patients with possible liver injury unrelated to rotavirus. Among the 92 patients identified with rotavirus during the study period, 75 had serum specimens available for testing. Fifteen patients (20%) had elevated ALT and AST, including one patient with an increase in AST, ALT, alkaline phosphatase, and total and direct bilirubin. The mean ALT elevation was 56 IU/L (range, 44 to 114 IU/L), and the mean AST elevation was 80 IU/L (range, 57 to 126 IU/L). Fifty-three patients (71%) had an increase in AST alone, and three patients (4%) had an increase in AST and alkaline phosphatase. The mean AST values in these groups were 61 IU/L (range, 42 to 110 IU/L) and 79 IU/L (range, 59 to 96 IU/L), respectively. In conclusion, rotavirus commonly causes elevation of liver transaminases.
