Thirty eight patients with classic dengue fever, were studied from December 1999 up to April 2000. All of them acquired the infection in Paraguay; 66% of patients arrived at Buenos Aires metropolitan area within the viremia period. Given Aedes aegypti abundance in the region they represent a high risk for local transmission. Unusual clinical findings in these patients were diarrhea (29%), transitory rise of seric aspartate aminotransferase (52%) and pruritic rash in all cases. Only 15.7% showed a biphasic course and none of the five patients with hemorrhages had a positive loop test. These observations show that dengue fever could be misdiagnosed as gastroenteritis or flue-like illness. These patients remain at risk of suffering hemorrhagic dengue. DEN 1 has not been reported in Buenos Aires. This fact and the unusual number of imported cases, represent a serious public health problem.

A debilitated 9-yr-old female red panda (Ailurus fulgens fulgens) with a recent history of corticosteroid administration displayed anorexia, depression, and diarrhea for 2 days. Blood work revealed a moderate nonregenerative anemia, leukocytosis, hypokalemia, hyperbilirubinemia, and mildly elevated alanine aminotransferase and aspartate aminotransferase. Serology was negative for occult heartworm, Toxoplasma gondii, feline leukemia virus, feline infectious peritonitis, feline immunodeficiency virus, and canine distemper virus. Electron microscopy of the feces demonstrated corona-like virus particles. The panda died 3 days after initial presentation. Histologic findings included multifocal, acute, hepatic necrosis and diffuse, necrotizing colitis. Liver and colon lesions contained intracellular, curved, spore-forming, gram-negative, silver-positive rods morphologically consistent with Clostridium piliforme. This panda most likely contracted Tyzzer's disease subsequent to having a compromised immune system after corticosteroid administration and concurrent disease.

A 7-year-old castrated male Golden Retriever cross was evaluated because of intermittent blood-tinged diarrhea, severe weight loss, anorexia, and lethargy of 2 months' duration; the dog was unresponsive to antimicrobial and standard anthelmintic treatment. Results of fecal flotations for parasite ova were negative. Alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase activities and total protein and globulin conentrations were greater than reference ranges. Biopsy specimens were obtained during laparotomy and examination revealed multiple granulomatous lesions with helminth ova nidi in the intestine, pancreas, liver, and mesenteric lymph node. Saline solution direct smear and saline solution sedimentation of feces yielded trematode ova that were morphologically consistent with Heterobilharzia americana. Identification was confirmed when miracidia were hatched from these ova and produced characteristic cercariae from infected snails. An antigen capture ELISA, typically used for the diagnosis of schistosomiasis in humans, was performed, and schistosome circulating anodic antigen was detected. Treatment with 30 mg of praziquantel/kg (14 mg/lb) of body weight stopped ova shedding, removed detectable circulating antigens, and caused the dog's body weight and attitude to return to normal. Although this is the first report of canine heterobilharziasis in North Carolina, it suggests that heterobilharziasis is underdiagnosed in dogs that have contact with water frequented by raccoons. Inappropriate diagnostic procedures can foil accurate detection of this parasitic disease.

The toxic effects of diet containing 10% of C. senna L. fruits or 10% of N. oleander L. leaves or their 1:1 mixture (5% + 5%) on male Wistar rats treated for 6 weeks were investigated. Diarrhea was a prominent sign of C. senna L. toxicosis. In both phytotoxicities, there were decreases in body weight gains, inefficiency of feed utilization, dullness and enterohepatonephropathy. These findings accompanied by leukopenia and anemia were correlated with alterations of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities and concentrations of total protein, albumin, urea and other serum constituents. In both phytotoxicities, the ability of the liver to excrete bilirubin remained unchanged. Feeding the mixture of C. senna L. fruits and N. oleander L. leaves caused more serious effects and death of rats. The implications of these findings are discussed.

A 37-year-old woman presented with increasing abdominal pain and jaundice. Six weeks before admission, she developed persistent diarrhea and jaundice of the skin. She also bruised easily, and her gums bled. In the subsequent weeks, her appetite decreased, she was fatigued, and she had nausea, vomiting, and abdominal distension. She had a history of drinking 1 quart of vodka every day for 20 years, with brief periods of abstinence; she stopped consuming alcohol 11 days before admission because it no longer provided symptomatic relief. Her past medical history was also notable for depression, including a suicide attempt 4 years earlier. She did not smoke, use illicit drugs, or have unprotected sexual intercourse. She had received no blood transfusions and had not traveled recently. She took no medications, except for occasional ibuprofen. On physical examination, she was thin and deeply jaundiced, and she trembled and responded slowly to questions. She was afebrile but tachypneic, and she had orthostatic hypotension. Her HEENT examination was notable for scleral and sublingual icterus, as well as crusted blood on her gums and teeth. The jugular veins were flat. The cardiac examination revealed tachycardia (heart rate, 103 beats per minute) without murmurs, rubs, or gallops. The abdomen was nontender and protuberant, with hypoactive bowel sounds; the spleen was not palpable, and there was no fluid wave or caput medusae. The liver percussed to 18 cm, with a smooth edge extending 10 cm below the costal margin. She had cutaneous telangiectases on her chest and bilateral palmar erythema. There was no peripheral edema. The neurologic examination was notable for asterixis. Her stool was guaiac positive. Laboratory studies revealed the following values: hematocrit, 21.2%; white blood cells, 17,310/mm(3); ammonia, 42 micromol/L; serum creatinine, 3.9 mg/dL; serum urea nitrogen, 70 mg/dL; albumin, 2.1 g/dL; total bilirubin, 26.8 mg/dL; alanine aminotransferase, 14 U/L; aspartate aminotransferase, 77 U/L; alkaline phosphatase, 138 U/L; prothrombin time, 103 seconds (international normalized ratio, 10.6); and urinary sodium, <5 mg/dL. Urinalysis revealed an elevated specific gravity and numerous muddy granular casts. Hepatitis A, B, and C serologies were negative. On abdominal ultrasound examination, there was no ascites, and the liver was echogenic. The portal and hepatic veins were patent, and the hepatic arteries were normal. The spleen measured 14 cm. What is the diagnosis?

The association between macroamylasaemia and coeliac disease in Down syndrome with multiple autoimmune abnormalities has never been reported. A 40-year-old woman with a 15-year history of immunoglobulin A and immunoglobulin M hypergammaglobulinaemia, chronic diarrhoea, persistent mild aspartate aminotransferase (AST) elevation and anaemic syndrome was admitted to hospital because in the previous 3 months she had developed amenorrhoea, dizziness, alopecia, constipation, pallor and asthenia. Biochemical and immunological analyses showed macroamylasaemia. The patient presented clinical and intestinal histopathological features of coeliac disease. Immunological abnormalities included the presence of antigliadin, antiendomysium, antitransglutaminase, antinuclear, antismooth muscle and anti-SSA/Ro antibodies. Macroamylase resulted in a complex of amylase and immunoglobulin A. Later clinical follow-up of a gluten-free diet showed a transitory decrease in seric immunoglobulin A and macroamylase with persistent autoantibodies and AST elevation. An intestinal mucosal immune disorder could lead to coeliac disease and macroamylasaemia in a patient with Down syndrome presenting other immune alterations.

A study was conducted to evaluate the effects of ochratoxin A (OA) on Escherichia coli-challenged broiler chickens. Day-old broiler chicks were separated into two groups of 92 chicks each, with one group fed a control mash diet, and the other fed a mash diet containing 2 ppm OA. On day 14, each group was further separated into two groups, with one group inoculated with E. coli O78 (1 x 10(7) colony-forming units/0.5 ml), whereas the other group was not inoculated with E. coli. After E. coli inoculation on day 14, four birds from each group were euthanatized at 1, 2, 3, 5, 7, 10, 14, and 21 days postinoculation. Escherichia coli infection caused dullness, depression, huddling, and diarrhea. Mortality was 14.3% in chicks infected with E. coli but fed no OA. Mortality increased to 35.7% in chicks fed OA and infected with E. coli. Decreased body weight and reduced feed intake were observed in chicks fed OA, and the effects were more pronounced in chicks fed OA and infected with E. coli. Increased serum levels of aspartate aminotransferase, alanine aminotransferase, uric acid, and creatinine and decreased levels of total proteins, albumin, globulins, calcium, and phosphorus were observed in OA-fed birds. Escherichia coli infection did not cause significant alteration in any of the serum biochemical parameters. The presence of OA in poultry rations increased mortality and the severity of an E. coli infection.

A 14-month-old female with familial dysautonomia was referred to the pediatric department with high fever (41.6 degrees C), watery diarrhea, and vomiting. A few hours later, signs of encephalopathy appeared. Laboratory tests revealed elevated levels of lactate dehydrogenase (3500 U/L), aspartate aminotransferase (640 U/L), alanine aminotransferase (320 U/L), and creatine kinase (28,420 U/L). The diagnosis was heat stroke. Impaired autonomic nervous system function may be another risk factor for the development of heat stroke in young children.

Miltefosine has previously been shown to cure 97% of cases of visceral leishmaniasis (VL) in Indian adults. Because approximately one-half of cases of VL occur in children, we evaluated use of the adult dosage of miltefosin (2.5 mg/kg per day for 28 days) in 80 Indian children (age, 2-11 years) with parasitologically confirmed infection in an open-label clinical trial. Clinical and parasitological parameters were reassessed at the end of treatment and 6 months later. One patient died of intercurrent pneumonia on day 6. The other 79 patients demonstrated no parasites after treatment, had marked clinical improvement, and were deemed initially cured. Three patients had relapse, and 1 patient was lost to follow-up. The final cure rate was 94% for all enrolled patients and 95% for evaluable patients. Side effects included mild-to-moderate vomiting or diarrhea (each in approximately 25% of patients) and mild-to-moderate, transient elevations in the aspartate aminotransferase level during the early treatment phase (in 55%). This trial indicates that miltefosine is as effective and well tolerated in Indian children with VL as in adults and that it can be recommended as the first choice for treatment of childhood VL in India.

A novel black tea decoction containing vanadate has successfully replaced insulin in a rat model of insulin-dependent diabetes but is untested in non-insulin-dependent diabetic animals. A tea-vanadate decoction (TV) containing 30 or 40 mg sodium orthovanadate was administered by oral gavage to two groups of Zucker diabetic fatty rats and a conventional water vehicle containing 30 or 40 mg of sodium orthovanadate to two others. In the latter group receiving the 30-mg dose, vanadate induced diarrhea in 50% of the rats and death in 10%. In contrast, TV-treated rats had no incidence of diarrhea and no deaths. Symptoms were more severe in both groups with higher vanadate doses, so these were discontinued. After approximately 16 weeks, the level of vanadium in plasma and tissue extracts was negligible in a further group of untreated rats but highly elevated after vanadate treatment. Vanadium levels were not significantly different between the TV-treated diabetic rats and the diabetic rats given vanadate in a water vehicle. Over the 115 days of the study, blood glucose levels increased from approximately 17 to 25 mmol/L in untreated diabetic rats. This was effectively lowered (to <10 mmol/L) by TV treatment. Fasting blood glucose levels were 5, 7, and 20 mmol/L in control (nondiabetic, untreated), TV-treated and untreated diabetic rats, respectively. Rats required treatment with TV for only approximately 50% of the days in the study. Increase in body mass during the study was significantly lower in untreated diabetic rats (despite higher food intake) than the other groups. Body mass gain and food intake were normal in TV-treated rats. Water intake was 28 mL/rat daily in control rats, 130 mL/rat daily in untreated diabetic rats, and 52 mL/rat daily in TV-treated diabetic rats. Plasma creatinine and aspartate aminotransferase levels were significantly depressed in untreated diabetic rats, and TV treatment normalized this. Our results demonstrate that a novel oral therapy containing black tea and vanadate possesses a striking capacity to regulate glucose and attenuates complications in a rat model of type II diabetes.
