Psittacine inclusion body hepatitis (also known as Pacheco's parrot disease) was believed to be responsible for fatal necrotizing hepatitis and splenitis in a variety of psittacine birds from a private aviary. Splenic cells and degenerative hepatocytes around the outer zone of necrotic areas had margination of nuclear material and large intranuclear inclusion bodies. Clinical signs consisted of weakness, anorexia, vomiting, loose feces, and slight ruffling of feathers. The source of the infection was undetermined, but could have been associated with 3 Patagonian conures within the aviary. Patagonian conures are well-recognized as clinically normal carriers. The outbreak was limited by strict quarantine and disinfection of the aviary for 14 days.

Ten Kenyan patients with visceral leishmaniasis unresponsive to sodium stibogluconate, at a dose of 16 to 20 mg Sb/kg body-weight/day given for 30 to 98 days, were treated with 20 mg Sb/kg bw given every eight hours. This regimen was modified or abandoned in six patients because of suspected toxicity, although toxicity was difficult to assess because of intercurrent illness. Toxic effects included lethargy, anorexia, vomiting, electrocardiographic changes, fall in haemoglobin and rise in liver enzymes. One patient died, probably from a cardiac arrhythmia. Two patients were cured, four responded partially and four showed no response. Pentamidine, at a dose of 4 mg/kg body-weight given one to 3 times per week for 5 to 39 weeks, was given as initial treatment in one patient and after failure of sodium stibogluconate in seven. Toxic effects included nephritis, hepatitis, transient diabetes and subcutaneous abscesses. Two patients were cured, two responded partially, three showed no response and one, after apparent cure, relapsed and was unresponsive to additional pentamidine treatment. Low-frequency, long-duration pentamidine was often useful in maintaining any improvement made during treatment with the less well tolerated high-dose, high frequency sodium stibogluconate. We observed the step-wise development of resistance to both sodium stibogluconate and pentamidine. The problems of managing patients with visceral leishmaniasis which is unresponsive to conventional doses of pentavalent antimonials are discussed and some tentative suggestions put forward.

Differential diagnosis of viral hepatitis begins with a check for darkened urine and bile in the urine. These hallmarks of conjugated hyperbilirubinemia immediately rule out prehepatic liver disease. Next, studies are done for the elevated transaminase levels that are characteristic of hepatitis infection, and a thorough history is taken to rule out drug- and toxin-induced hepatitis that may mimic acute viral hepatitis. Elevated alkaline phosphatase is a good marker of cholestasis. Ultrasonography can clarify this diagnosis. The classic presenting symptoms of viral hepatitis are jaundice, nausea, vomiting, malaise, anorexia, and dull right upper quadrant pain. However, serologic studies are needed to detect the presence of specific viral agents.

A 3-month-old girl presented with anorexia, failure to thrive and drowsiness. She was mildly icteric with hepatomegaly and peripheral oedema. Disordered liver function tests were associated with the biopsy appearances of a giant cell hepatitis and with a Fanconi syndrome. At the age of 16 weeks she collapsed with profound hypoglycaemia. Fasting also provoked hypoglycaemia with lactic acidaemia. She became increasingly irritable and hypotonic and, although initially liver and renal function improved, she deteriorated and died of hepatocellular failure and septicaemia. A post-mortem revealed massive fatty degeneration of the liver. The activity of phosphoenolpyruvate carboxykinase in her cultured skin fibroblasts was 16% of controls. Her brother died at the age of 4 weeks of sudden infant death syndrome.

Recombinant human interleukin 2 was administered to 10 patients with chronic type B hepatitis as a part of a pilot study to evaluate its antiviral activity. Patients received 1 to 3 x 10(5) units per day of interleukin 2 for 21 to 28 days, and all completed the treatment schedule. During therapy, serum values of DNA polymerase decreased in 6 and became negative in four patients. However, when therapy was discontinued, DNA polymerase levels increased to pretreatment levels in most cases. Serum HBeAg levels did not change during treatment. Serum aminotransferase levels transiently increased in 6 of the 10 patients during therapy; but once therapy was stopped, levels fell markedly. Side effects of interleukin 2 therapy included fever, chills, anorexia and fatigue. After 1 year of follow-up, three treated patients had lost HBeAg and had marked improvement in aminotransferase levels. These serologic and biochemical improvements occurred 1.5 to 11 months after therapy was stopped. Whether a 3- to 4-week course of interleukin 2 therapy leads to an increased rate of seroconversion from HBeAg to antibody in chronic type B hepatitis deserves further evaluation in prospectively randomized, controlled trials.

Homologous and heterologous haemagglutination-inhibition (HAI), complement-fixation (CF), immunodiffusion (ID) and mouse neutralization tests were performed with the Lunyo (LUN) and a Zimbabwean strain of Rift Valley fever (RVF) virus, the prototype and a South African strain of Arumowot (AMT) virus and prototype strains of Gordil (GOR), Saint-Floris (SAF) and Gabek Forest (GF) viruses, using immune mouse ascitic fluids prepared against these viruses. Reactions of identity occurred in all tests between LUN and the Zimbabwean strains of RVF and between the two strains of AMT virus. Otherwise, cross-reactions occurred between all the phleboviruses in HAI tests, while reactions in CF, ID and neutralization tests were monospecific for virus serotypes, except that weak cross-reaction occurred between GOR and SAF viruses in CF and ID tests. Four sheep infected subcutaneously with the Zimbabwean strain of RVF virus developed transient fever, viraemia, leucopaenia, relative thrombocytopaenia, haemoconcentration and raised serum enzyme levels, which indicated that the sheep had developed necrotic hepatitis. Disseminated focal necrotic hepatitis was confirmed in a sheep killed for examination on day 4 post-infection. The other three sheep recovered uneventfully after only mild depression and anorexia. Groups of three sheep infected with SAF, GOR, AMT and GF viruses had no demonstrable viraemia or other sign of infection or illness, except that the sheep infected with AMT developed mild fever lasting less than 24 h. Antibody responses were monitored at intervals over a period of 24 weeks in all sheep by homologous and heterologous HAI, CF and cell culture neutralization (CPENT) tests. Homologous antibody responses were marked in the RVF-infected sheep and their sera cross-reacted strongly in HAI tests with antigens of the other viruses. The sera of the RVF-infected sheep cross-reacted less markedly in CF and CPENT tests. Homologous antibody responses were poor in all the sheep infected with phleboviruses other than RVF, and the cross-reactivity of their sera for RVF antigen or virus was negligible. All sheep were challenged with RVF virus 48 weeks after their initial infection. The sheep which had originally been infected with RVF virus were immune and developed neither fever nor viraemia. All other sheep developed fever, viraemia and antibodies to RVF virus. It was concluded that the African phleboviruses, other than RVF, are unlikely to cause disease in livestock or to induce antibodies which could cause confusion in the diagnosis of RVF.

From 1980 to 1984, forty-five patients suffering gastric cancer were irradiated with curative intent. Twenty-three were considered at high risk of recurrence after complete surgical resection (invasion of the serosa, lymph nodes and/or surgical margins); eleven were treated after partial resection, and for eleven others, the local extension precluded surgery. Radiotherapy combined two lateral fields (usually with wedge filters) and an anterior field. The planned dose was 40 to 50 Gy, according to the amount of residual disease and doses delivered to the major part of the liver and the right and left kidneys did not exceed 30, 5, and 18 Gy, respectively. For patients aged less than 71 and whose general condition was acceptable, one cycle of chemotherapy (FAM for 20 patients and 5-FU for 10) preceded irradiation, followed if possible by 6 other cycles. Adverse effects, essentially anorexia, vomiting, and weight loss, led to definitively stopping irradiation in 8 cases, and were present in 21 other patients. Mean weight loss was 2.5 kg. Apart from one patient who developed a subphrenic abcess and died after reoperation, there was neither chronic complication, nor radiation hepatitis or nephritis. For 34 patients, the observation time was superior to 3 years: 23 died of their cancer, 1 of a subphrenic abcess, and 2 of an intercurrent disease. Eight were disease-free at 3 years (three of these were irradiated for macroscopic disease). For the overall series, the 4-year survival rate is 23%. There is a significant survival advantage for females versus males (p less than 0.01), a non-significant tendency in favor of microscopic residual disease versus macroscopic, and no advantage for the combination with FAM compared with no chemotherapy (non-randomized). This technique appears feasible with an acceptable tolerance and can control local tumor in a few cases. The planned dose of 40 Gy was probably too small and we are now testing 45 Gy delivered over the large initial volume, and boosts of 10-15 Gy to residual disease.

Aflatoxins are hepatotoxic in many species including dogs. In two separate outbreaks, the primary signalment was high morbidity and mortality in hunting dogs presenting with clinical signs of icterus, anorexia and listlessness. Preliminary laboratory examinations revealed toxic hepatitis, bilirubinuria and anemia. In the first case, a feed sample was not available and the diagnosis was established by confirming the presence of significant levels of aflatoxin B1 in tissues. In the second case, cornmeal utilized in formulating the ration contained 511 ng aflatoxin B1 and B2/g. These cases illustrate that aflatoxicosis is a continuing problem despite widespread awareness and testing for aflatoxin.

The clinical findings during a major epidemic of Q-fever which affected 415 people in the Val de Bagnes (Valais, Switzerland) in the autumn of 1983 are reported. Q-fever symptoms were evident in 191 cases but inconspicuous or absent in 224 cases. The symptoms most frequently reported were prolonged high fever, headaches, severe exhaustion, loss of appetite, cough and myalgia. Amongst disorders which accompany acute Q-fever, pneumonia and granulomatous hepatitis are very frequent, while myopericarditis and glomerulonephritis are less frequently observed. Endocarditis, a later complication of Q-fever, is a severe illness which more frequently affects patients with underlying valvular lesions. New serological techniques now permit more rapid and more accurate diagnosis of both acute and chronic Q-fever.
