A randomized double blind study in long term malaria chemoprophylaxis was performed to compare the tolerability of Fansimef (1 tablet containing 250 mg mefloquine + 500 mg sulfadoxine + 25 mg pyrimethamine per week) with chloroquine (300 mg per week). 211 Austrian industrial workers and their families in Warri, Nigeria, participated in this study; 101 received Fansimef and 110 chloroquine for 3-18 months (mean 41 weeks). Prophylaxis was discontinued because of adverse effects in 7 volunteers in the Fansimef group (mainly insomnia, palpitations, dizziness, nausea and headache) and in 2 volunteers of the chloroquine group (headache and loss of hair in one volunteer, nausea, dizziness and vomiting in the other). Most of the adverse effects could be due to the mefloquine component. A few minor complaints of burning eyes, nausea and gastric pain were reported in both groups. Laboratory checks performed at 3-monthly intervals showed a slight, transient and clinically irrelevant (but statistically significant) increase of serum glutamic-oxalacetic transaminase and gamma-glutamyl transpeptidase at month 3 in the Fansimef group. An attack of acute Plasmodium falciparum malaria occurred in one volunteer 6 weeks after discontinuation of prophylaxis with Fansimef. Antibodies against blood stage parasites could be demonstrated by the indirect immunofluorescence test at different stages of the study, indicating that these two antimalarials are not causal prophylactic agents.

We report the biochemical results in 90 women presenting to an eating disorders clinic: 61 who had bulimia, 22 with anorexia nervosa and seven unclassified. The results were compared with 30 control women. The group of women with an eating disorder had significantly higher concentrations of total CO2, calcium, AST, ALT, ALP, albumin and cholesterol and significantly lower concentrations of potassium, chloride and phosphate in the plasma. The elevated calcium could be accounted for in part by an increase in total CO2 and an increase in albumin. Hypokalaemia was strongly associated with self-induced vomiting and laxative abuse. Biochemical abnormalities occurred in both forms of eating disorders; however, hypercholesterolaemia was more common in anorexia nervosa and abnormal liver enzymes were more common in bulimia.

Experimental and clinical experience with compounds containing antimony have shown that the trivalent compounds are generally more toxic than the pentavalent ones. APT can cause severe pain and tissue necrosis and is therefore not given by intramuscular or subcutaneous injection. APT has the actions and uses of AST, but it is less soluble and more irritating than the sodium salt which is therefore more suitable for intravenous use. Trivalent antimony compounds are toxic when used topically. Adverse effects are similar for all trivalent compounds, and include nausea, vomiting, weakness and myalgia, abdominal colic, diarrhoea, and skin rashes, including pustular eruptions. Hypersensitivity reactions also occur. Respiratory symptoms include cough, dyspnoea, and chronic lung changes. Cardiotoxicity is the most important and may produce arrhythmias, myocardial depression and damage, Stokes-Adams attacks, heart failure, and cardiac arrest. Hepatic damage and necrosis, as well as blood dyscrasias, may occur. Toxic effects on the kidney may follow chronic use. Continuous treatment with small doses of antimony may give rise to symptoms of subacute poisoning, similar to those of chronic arsenic poisoning, due to accumulation of antimony in the body, especially if trivalent compounds are used, because of their long biological half-lives. Reproductive disorders and chromosome damage have been reported; antimony compounds are, therefore, potentially toxic to reproduction and have mutagenic, and oncogenic potential. Antimony compounds should, therefore, not be used during pregnancy or in the presence of hepatic, renal, or heart disease. Pentavalent antimony preparations especially the organic compounds, together with non-metallic synthetic preparations, such as the diamidines, have now replaced APT for use in leishmaniasis. Because of the toxicity of antimony compounds, investigations have been undertaken to reduce their adverse effects by combining them with chelating agents. These preparations appear to have reduced the toxic effects of antimony without affecting the efficacy of the preparations. Liposome-encapsulated antimony products have, more recently, been shown to be much less toxic because of the reduced dose of the antimony compound required for effective therapy. The historical uses of antimony were based on the belief that the topical and systemic adverse effects, for example, skin eruptions and diarrhoea and vomiting, were signs that the condition being treated was responding by being brought to the surface to relieve congestion at the diseased area. There is no evidence in topical use, but there is evidence that such use can cause severe reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

An open clinical study of ofloxacin in respiratory tract infections was conducted with patients receiving daily doses of ofloxacin 300 mg, 400 mg or 600 mg. The duration of treatment was 6 to 14 days for 70% of the patients. Ofloxacin was effective in 668 of 828 patients analysed (80.7%). Of 293 patients with upper respiratory infections, the efficacy rate was 85.3%. In 535 cases with lower respiratory infections, ofloxacin was effective in 78.1%. It is noteworthy that a 70% efficacy rate was obtained in 80 cases with intractable chronic diffuse panbronchiolitis primarily associated with Pseudomonas aeruginosa. There was no difference in the efficacy rate among various daily doses or severity of infections. In lower respiratory infections the bacterial eradication rate was 80.9% for Gram-positive aerobes (including 80% for Staphylococcus aureus and 76.5% for Streptococcus pneumoniae) and 72.1% for Gram-negative aerobes (including 92.6% for Klebsiella pneumoniae, 32.3% for P. aeruginosa and 97.1% for Haemophilus influenzae). Although there were no serious cases, adverse reactions were noted in 46 of 843 patients (5.5%): 38 cases (4.5%) of gastrointestinal tract reactions (nausea, vomiting, heartburn, etc.), 4 cases (0.5%) of hypersensitivity (e.g. eruption) and 19 (2.3%) of central nervous system effects (e.g. dizziness). Abnormal changes in laboratory findings included elevations of AST (1.2%) and ALT (1.5%) and an increase in the eosinophil count (1.7%).

The acute intravenous, intragastric, subcutaneous, intraperitoneal and intratracheal toxicity of T2 toxin has been studied in rats, mice, guinea-pigs, and pigeons. The acute LD50 values obtained varied between 1.0 and 14 mg X kg-1, there being little difference between the various routes in any given species. T2 caused vomiting in pigeons at doses of one fifth or less the LD50. In rats doses of 3.0 and 5.0 mg X kg-1 T2 produced lymphopenia, reticulocytosis, and in the highest dose groups normoblastaemia. Additionally, changes in plasma alkaline phosphatase and aspartate aminotransferase activities were seen. Histological changes were observed in lymphoid organs and were most severe in the thymus, lymph nodes, and Peyer's patches. The spleen was less severely affected. Gastrointestinal changes consisting of dead and dying lymphoid cells throughout the lamina propria were seen together with, in some cases, mucosal ulceration. The time course of the development and of the reversal of the changes was followed.

Clinical and laboratory features of 86 infants admitted with diarrhea and dehydration were evaluated prospectively. Human rotavirus (HRV) infection was documented in 35 infants (41%) by the Rotazyme test. Those with HRV gastroenteritis (HRV+ group) had a shorter duration of diarrhea prior to admission, more severe dehydration on presentation, and a longer hospital course than the HRV-negative (HRV-) group. Vomiting, fever, upper respiratory tract symptoms, otitis media, and cough were present in equal numbers of infants in both groups. The HRV+ infants had lower serum bicarbonate and higher serum albumin, alanine aminotransferase, aspartate aminotransferase, and uric acid concentrations than did the HRV- infants. Serum uric acid levels greater than 10 mg/dL (590 mumol/L) were present in 69% of HRV+ vs 29% of HRV- infants. The Rotazyme test was found to be a valuable tool in diagnosis; testing on two days increased the yield from 74% to 97% of all infants finally diagnosed as HRV+. The optimal time for testing was within the first five days of illness.

Analysis of 56 patients with obstructive jaundice due to carcinoma of the pancreas or extrahepatic biliary tree showed that unexpected features were present in 25%. Presentation with painless jaundice was uncommon, and the symptoms were more often non-specific, with malaise, anorexia, and vomiting. Abdominal pain was frequent, and the condition was found in young patients. One-fifth presented with serum alkaline phosphatase levels of less than 30 K.A. units. Some had high serum aspartate aminotransferase levels, more characteristic of hepatocellular jaundice. A mathematical model may be helpful in correctly weighting these various criteria.

In a model developed to study acute pancreatitis in the dog, the disease process was comparable with the spontaneously occurring disease. Infusion of oleic acid into the accessory pancreatic duct induced, grossly and microscopically, acute hemorrhagic pancreatitis with pancreatic atrophy, fibrosis, fat necrosis, and edema. Clinical changes included persistent fever and tachycardia in all dogs and abdominal pain, vomiting, and diarrhea in most. Serum amylase and lipase activities increased markedly as did activities of alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase. Hematologic alterations included hemoconcentration (despite intensive fluid therapy) and leukocytosis due primarily to neutrophilia and monocytosis. Neither corticosteroid nor anticholinergic therapy begun 24 to 32 hours after oleic acid infusion altered the course of the disease. Dogs survived 8 days and appeared clinically normal when the study was terminated.

Bile duct obstruction was induced in 6 cats by surgical ligation and transection of the common bile duct. Clinical and laboratory changes were monitored weekly for 25 to 54 days. Clinical signs of obstruction were similar in all cats and included anorexia, pyrexia, lethargy, intermittent vomiting, weight loss, palpable gallbladder, hepatomegaly, and bleeding tendencies. Tissue jaundice and acholic feces were evident grossly as early as postsurgical day (PSD) 4 with a mean onset of jaundice at PSD 5.3 +/- 0.4. Hematologic changes were initially characterized by a mild neutrophilic leukocytosis that increased with the chronicity of bile duct obstruction. Regenerative anemia developed in 4 cats associated with gastrointestinal blood loss. Acute serum biochemical changes were characterized by a marked increase in the mean values of aspartate aminotransferase, alanine aminotransferase, total cholesterol, and copper. Comparatively, only moderate increases in mean serum alkaline phosphatase activity were observed. Mean total bilirubin values increased remarkably at postsurgical week (PSW) 1, reaching a maximal value of 23.1 +/- 4.4 mg/dl at PSW 3 with 71.6 +/- 2.7% direct bilirubin. With chronicity of bile duct obstruction ranging from PSW 3 to PSW 7, the mean serum values of aspartate aminotransferase, alanine aminotransferase, total cholesterol, serum alkaline phosphatase, and total and direct bilirubin stabilized and then declined, whereas the increased mean serum copper values persisted. At PSD 25 to 54, hepatic copper values and serum bile acids were markedly increased. Seemingly, clinicopathologic changes of induced cholestatic hepatic injury depended largely on the duration of biliary obstruction.(ABSTRACT TRUNCATED AT 250 WORDS)

In a one-year prospective study we assessed the incidence of Reye's syndrome in children presenting with the acute onset of vomiting after a prodromal upper-respiratory-tract infection or varicella, and with serum alanine or aspartate aminotransferase levels at least three times higher than normal, and a paucity of neurologic findings. Of 25 patients meeting the above criteria, 19 had liver biopsies yielding adequate tissue for diagnostic purposes. Biopsy specimens from 14 of these 19 patients (74 per cent) were diagnostic of Reye's syndrome, according to rigorous light-microscopical, histochemical, and ultrastructural criteria. None of the biopsy specimens contained evidence of other acute pathologic processes, including hepatitis. A wide spectrum of mitochondrial alterations existed at the ultrastructural level, ranging from mild to severe lesions that were indistinguishable from those seen in comatose patients with Reye's syndrome. Our findings suggest that the clinical complex of vomiting, hepatic dysfunction, and minimal neurologic impairment after varicella or an upper-respiratory-tract infection usually represents Reye's syndrome. This syndrome occurs more frequently than previously recognized.
