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.

Twenty previously treated patients with advanced bone sarcomas received thrice weekly im 50 X 10(6) IU/m2 doses of human alfa-interferon (interferon alfa-2a, recombinant; Roche). Seventeen patients had metastatic osteosarcomas and one each had fibrosarcoma, mesenchymal chondrosarcoma, and malignant fibrous histiocytoma. Two patients with osteosarcoma and the one with malignant fibrous histiocytoma experienced objective partial tumor regression for 1, 3, and 2 months, respectively. Fever, anorexia, myalgia, fatigue, lethargy, and moderate myelosuppression were observed commonly, and some patients developed mild nausea, vomiting, and diarrhea. No patient withdrew because of toxicity and no dose reductions were necessary except adjustments for changes in body surface area secondary to weight loss.

The most commonly recognized behavioral patterns of animals and people at the onset of febrile infectious diseases are lethargy, depression, anorexia, and reduction in grooming. Findings from recent lines of research are reviewed to formulate the perspective that the behavior of sick animals and people is not a maladaptive response or the effect of debilitation, but rather an organized, evolved behavioral strategy to facilitate the role of fever in combating viral and bacterial infections. The sick individual is viewed as being at a life or death juncture and its behavior is an all-out effort to overcome the disease.

Eighteen patients with solid tumours were treated with human recombinant interferon-gamma at escalating dose levels starting at 1 X 10(6) units/m2 per infusion and rising through 3 X 10(6), 6 X 10(6), 9 X 10(6) and 22 X 10(6) to a maximum of 110 X 10(6) units/m2 per infusion. The IV infusions were given three times a week over a 4-week period. Side effects were seen in all patients, but were mild except at the highest dose. Acute dose-related effects included pyrexia, tiredness, thirst, chills and rigors. Chronic dose-related effects included anorexia, lethargy, weakness, disorientation, a trace of proteinuria and minimal rises in liver enzymes. In addition, effects were observed which were not related to dose. These included headache, nausea and vomiting, backache, myalgia, flatulence and a mild, transient reduction in neutrophils and erythrocytes. At the highest dose level dose-limiting toxicity was observed, consisting in severe tiredness and anorexia, hypotension, disorientation and changes on the electrocardiograph. Overall, toxicity was similar to that seen with preparations of interferon-alpha, except that no tolerance to the effects of interferon-gamma was noted. We observed less hepatic and haematological toxicity, but also recorded flatulence, handcramps and electrocardiograph changes, which have not been reported with interferon-alpha. When given according to this regimen, doses of 22 X 10(6) units/m2 per infusion of recombinant interferon-gamma were generally well tolerated by the patients.

24 patients with advanced, histologically proven cancer were treated with difluoromethylornithine 2.25 g/m2 orally every 6 h for the first 7 days of each 4-week treatment cycle. These patients also received daily i.m. doses of recombinant human alpha 2a-interferon (IFN) on Days 3 through 7 of each cycle. IFN doses of 3, 6, 12, 24, 36, and 48 X 10(6) units/m2 have been studied utilizing three patients at each daily dose level. Three additional patients have been observed at each of the two highest doses for better toxicity definition. This combination produced slight transient declines in leukocyte and platelet counts and transient rises in serum aspartate aminotransferase; however, these changes were no more pronounced at the higher IFN doses than at daily doses of 6 X 10(6) units/m2. Mild nausea and vomiting occurred in most patients and mild diarrhea also was common at all IFN dose levels. Chills, fever, myalgia, lethargy and fatigue, and anorexia were also observed at all IFN doses; however, lethargy and fatigue (lassitude) seemed to be the major factor which limited patient tolerance of IFN to 48 X 10(6) units/m2 daily. No ototoxicity was identified clinically or audiometrically and no life-threatening toxicity has occurred. Initial Phase II studies in melanoma are currently in progress.

To evaluate the health effects of occupational phosphine exposure, 22 workers engaged in fumigation of stored grains were subjected to a clinical and environmental study. These workers were used to placing aluminum phosphide tablets on the stacks of grains and covering it with a gas-proof plastic cover. The mean age of the workers was 48 years (range 24-60) and mean duration of exposure 11.1 years (range 0.5-29). After fumigation they reported minor symptoms, which included cough (18.2%), dyspnoea (31.8%), tightness around the chest (27.3%), headache (31.8%), giddiness, numbness and lethargy (13.6% each), anorexia and epigastric pain (18.2% each). The abnormal physical signs included bilateral diffuse rhonchi and absent ankle reflex each occurring in one worker. Motor nerve conduction velocity of median and peroneal nerves, and sensory conduction velocity of median and sural nerves were normal. Phosphine concentration in the work environment ranged from 0.17 to 2.11 ppm. Occupational phosphine exposure in the workers was associated with mild to moderate symptoms, which were transient. However, to assess the chronic effects, long-term follow-up is recommended.

Differentiating acute appendicitis from other causes of acute abdominal pain in children frequently remains unsatisfactory. To determine whether initial historical and physical examination findings might predict final diagnoses, 246 patients with complaints of nontraumatic and nonrecurrent acute abdominal pain were studied. All were between three and 18 years of age and had presented to a hospital-based pediatric emergency department. Each family was telephoned an average of 5.1 days after the visit to determine the patient's subsequent clinical course; operative notes and pathology reports were reviewed for patients receiving surgery. Of these patients with acute abdominal pain, both fever and vomiting were present in 18 of the 24 who eventually had diagnoses of appendicitis, compared with 49 of 222 patients with other final diagnoses (P less than 0.01, with negative predictive value 0.97, sensitivity 0.75, and specificity 0.78, but positive predictive value only 0.27). The duration of the pain at presentation and the frequency of other symptoms (eg, diarrhea, dysuria, anorexia, and lethargy) were unrelated, however, to final diagnosis, as was the duration of the pain and whether abdominal tenderness initially was localized or generalized. Nonruptured appendicitis was generally indistinguishable from ruptured appendicitis preoperatively, by both duration and symptoms. Boys were found more likely to have appendicitis (with or without rupture) than girls (18/118 or 15%, vs. 6/128 or 5%, P less than 0.05). In conclusion, fever and vomiting were noted at presentation more frequently in children with appendicitis than in children with other causes of acute abdominal pain.(ABSTRACT TRUNCATED AT 250 WORDS)

Pancreatic abscess was diagnosed by exploratory celiotomy in 6 dogs. The most common clinical signs included acute onset of lethargy (n = 5), anorexia (n = 6), vomiting (n = 5), and diarrhea (n = 2). Physical examination revealed pain response to abdominal palpation (n = 5), depression (n = 5), icterus (n = 3), fever (n = 3), and cranial abdominal mass (n = 2). Consistent preoperative clinicopathologic abnormalities included leukocytosis with left shift, observance of toxic neutrophils on the blood smear, hyperlipasemia, hyperamylasemia, hyperbilirubinemia, and increased serum alkaline phosphatase activity. In 5 of 6 dogs, abdominal radiography revealed increased soft tissue density in the cranial portion of the abdomen. Ultrasonography performed on 4 dogs confirmed pancreatic mass. In all dogs, exploratory celiotomy revealed a cavitary pancreatic mass that contained sterile, mucopurulent material. Histopathologic diagnoses included acute necrotizing or chronic-active pancreatitis and steatitis. Two dogs were euthanatized at the time of diagnosis, and the remaining 4 were treated by use of pancreatic debridement(s), open abdominal drainage, and intensive administration of fluids and antibiotics. One dog was euthanatized 4 days after surgery, because of progressive pancreatic abscessation. Three dogs recovered and were discharged.

Nine- to ten-week-old, male castrated, specific pathogen-free derived pigs, weighing 34 to 42 kg, were exposed to a T-2 toxin aerosol (390 micrograms/liter, 1.5 microM mass median aerodynamic diameter) for a time period which allowed an amount equivalent to 8 mg/kg to be nebulized (six pigs). Control animals (five pigs) were exposed to an equivalent amount of the nebulized vehicle. Pigs were immunized subcutaneously with sheep red blood cells on Days 0 and 21. Whole blood and serum samples were taken periodically for clinical pathologic and immunologic studies. Pigs were closely observed, and daily rectal temperatures and weekly weights were measured. The T-2-treated pigs vomited and exhibited cyanosis, anorexia, lethargy, lateral recumbency, slightly elevated rectal temperature, and depressed body weight gain. The lymphocyte count decreased while the neutrophil count increased. The concentrations of total serum protein and hemoglobin declined. There was a marked increase in serum alkaline phosphatase activity on Day 1, followed by a marked and persistent decrease. Mitogen-induced (Con A, PHA, and PWM) blastogenic responses of peripheral blood mononuclear cells and hemagglutination titers to SRBC were also transiently decreased. Thus, inhalation exposure of pigs to a sublethal dose of T-2 toxin caused clinical signs of toxicity and adverse effects on clinical pathologic parameters and immune responses; however, most of these effects were short-lived. The changes described in our study resemble those reported in pigs given T-2 toxin by intravascular injection.

The clinical and serologic features and immune status of 39 homosexual men who had seroconversion to human immunodeficiency virus positivity were compared with 26 homosexual men who remained seronegative during a six-month period. An acute clinical illness occurred in 92.3% of seroconverted subjects and 40% of controls. The duration of illness was significantly greater in the seroconverters than the controls (10 + 4.4 days). A general practitioner was consulted by 87.2% of the seroconverters because of the illness, including 12.8% who were admitted to hospital, compared with 20% of controls. The most frequently reported symptoms in the seroconversion group were fever (76.9%); lethargy and malaise (66.7%); anorexia, sore throat, and myalgias (56.4% each); headaches and arthralgias (48.7% each); weight loss (46.2%); swollen glands (43.5%); retro-orbital pain (38.5%); and dehydration and nausea (30.8% each). Lymphadenopathy developed in 75% of seroconverters compared with 4% of controls. Changes in T-cell subsets were not found in controls, but the number of T4+ cells and the T4+/T8+ ratio decreased significantly in seroconverters.
