The first pregnancy of a 22-year-old woman with somewhat more pronounced and prolonged symptoms of emersis gravidarum was followed up in the outpatient unit and was considered normal. The woman was admitted to the maternity ward 38 days before the term of labour because of painful abdominal cramps, vomiting and weakness. In the course of the first 17 days in hospital, the pregnancy was maintained by the use of spasmolytics but at that time it became clear on the basis of the symptoms, gynecological findings, and the gravidogram, that the case related to abdominal pregnancy. On the 18th day of hospitalization, laparotomy ws performed and a live, female, prematurely born baby, 2,450 g/45 cm, without any deformity, was delivered. The pregnancy was abdominal, with the nidation of the placenta at the right uterine horn. The placenta was completely removed. The girl is now 6 years old and her psychophysical development is normal, corresponding to her age.

Major findings from our work on exposures and effects from organophosphate-containing pesticides in selected occupational and community patients and groups in Israel are reviewed as a basis for recommending control measures. The worker groups were pilots, ground-crews, and field workers; exposed nonworkers were adults and children living in kibbutzim with drift exposures, and household residents in houses treated by pest exterminators. In all groups, evidence of exposure-illness associations was found even though persons with acute poisoning were not seen. Complaints (headache, dizziness, fatigue, nausea, breathing problems, abdominal cramps, and tingling in extremities) were associated with within-normal depressions in cholinesterase activity. Whole blood and plasma cholinesterase activity were slightly more sensitive indicators of mixed exposure than red blood cell cholinesterase activity. High alkyl phosphate levels and symptoms were seen in individuals with within-normal limit depressions in cholinesterase activity. Complaints of weakness and tingling in hands and feet, together with low-grade changes in nerve conduction, suggest the possible influence of agents with a neurotoxic esterase-type activity independent of cholinesterase activity. Transient in-season neuropsychological changes in tests of mood status and performance were associated with exposure. Recommendations for exposure reduction include: accelerating the already declining use of pesticides in general, and organophosphates in particular; promoting the shift from more to less toxic organophosphates and other pesticides; and introducing rigid performance specifications for closed systems in loading and mixing at end-user sites. Dermal protection remains a problem. Cholinesterase activity levels and symptom interviews are useful for monitoring workers at risk, but alkyl phosphate levels are the definitive measure of exposure, surveys, investigations and surveillance.

1. Three oral glucose tolerance tests were performed in each of 32 symptomatic postprandial hypoglycaemic patients (before placebo, before doxepin therapy and after doxepin therapy). Plasma neurotransmitters were determined in parallel with assays of plasma insulin and glucose levels. 2. Three different types of patients were distinguished. Type I showed a low noradrenaline/adrenaline ratio, high dopamine levels and low platelet 5-hydroxytryptamine (serotonin) levels during basal periods. After a glucose load, late peaks of dopamine and free 5-hydroxytryptamine, which coincided with the symptoms but not with the nadir of plasma glucose, were observed. Type II showed a low basal plasma noradrenaline/adrenaline ratio. After a glucose load, progressive increases in adrenaline and decreases in glucose were seen. Adrenergic symptoms coincided with the nadir of glucose. Although type III patients showed hyperinsulinaemia after a glucose load similar to the other types of patient, they did not show hyperglycaemia, but rather exhibited a sustained and progressive reduction in plasma glucose. These patients were characterized by a high basal plasma noradrenaline/adrenaline ratio, high basal plasma levels of 4-hydroxy-3-methoxyphenylethyleneglycol and high basal levels of platelet 5-hydroxytryptamine, all of which increased after a glucose load. Systolic and diastolic blood pressure decreases paralleled reductions in heart rate and glucose. The nadir of plasma glucose occurred simultaneously with the appearance of symptoms (weakness, heartburn, oppressive chest pain, tension headache, abdominal cramps, dizziness, etc.). Therapy with doxepin led to disappearance of the symptoms within 3-4 weeks. Normalization of all other disordered variables (cardiovascular, metabolic and neurochemical, and the clonidine test) paralleled the disappearance of the symptoms. 3. Symptoms varied in the three types of patients and we conclude that they are related to hypoglycaemia-induced disorders of plasma neurotransmitters, rather than to hypoglycaemia per se. We postulate that an uncoping stress situation (type I and II patients) and depression (type III patients) underlie the physiopathological mechanisms.

Pyridostigmine is known as a pre-treatment drug against intoxication with organophosphorus nerve agents. During the Persian Gulf war, we encountered a cluster of nine cases of pyridostigmine self-poisoning, of which three presented with mixed drug poisoning. The clinical and laboratory features of pyridostigmine toxicity are presented. Doses ranged between 390 and 900 mg. Pyridostigmine ingestion resulted in mild to moderate cholinergic symptoms such as abdominal cramps, diarrhea, emesis, nausea, hypersalivation, urinary incontinence, fasciculations, muscle weakness and blurred vision. No central nervous system manifestations were evident. The symptoms developed within several minutes and lasted up to 24 h. All patients underwent gastric emptying followed by administration of activated charcoal. Atropine (1-8 mg) was required in only three patients. Measurement of serum cholinesterase inhibition was found to be a reliable and sensitive diagnostic tool in pyridostigmine poisoning. No clear correlation was found between the extent of cholinesterase inhibition and the incidence or severity of the cholinergic signs. The clinical recovery was faster than the spontaneous recovery of the enzyme. Pyridostigmine intoxication is self-limited and well tolerated by young healthy adults.

An outbreak of Gnathostoma larva migrans occurred among guests of a New Year's party in Chachoengsao, Thailand. Nine people who consumed a raw fish dish called 'Hu-sae' contracted the disease. Five of them developed gastro-intestinal symptoms consisting of nausea, vomiting, abdominal cramps and diarrhea as early as within the first 24 hours, while in the other four, symptoms started on the following day. After the initial symptoms pertaining to the gut, malaise, chest discomfort, cough, myalgia, weakness, itching and migratory swellings were experienced. Eosinophilia was demonstrated in every patient with a mean (+/- SE) count of 5,516 +/- 1,010 cells/cu mm. Detection of antibody against aqueous extracts of G. spinigerum adult antigen using an enzyme-linked immunosorbent assay showed a titer of 1:1,600 or greater in every patients except one who had a titer of 1:400 (positive greater than or equal to 1:400). This outbreak illustrates the high attack rate when heavily infected fish are consumed.

An explosive outbreak of gastrointestinal illness occurred among students and employees at a small college in Florida in November 1980. Common symptoms were diarrhea, nausea, weakness, abdominal cramps, chills, vomiting, and low-grade fever. Cases of illness were identified in 40% of 628 students and 15% of 162 employees who responded to a survey. Among students, there was a sevenfold excess risk associated with eating one or more meals at the campus cafeteria November 3-5 (p much less than 0.001). Tossed salad from one meal was strongly associated with illness (p less than 0.0001). Fecal contamination of the salad was documented, although the source of contamination was not identified. Person-to-person spread could not be demonstrated. Seroconversion to Norwalk antigen occurred in significantly more cases (5/6) than noncases (1/6) (p = 0.04).

Although Bacillus cereus is a well-known cause of food-borne illness, hospital-related outbreaks of food-borne disease due to B. cereus have rarely been documented. We report a hospital employee cafeteria outbreak due to foods contaminated with B. cereus in which an outside caterer was employed to prepare the suspect meals. Data were collected from 249 of 291 employees who had eaten either of the two meals. With a mean incubation period of 12.5 hours, 64% (160 of 249) of employees manifested illness. Symptoms, which averaged 24.3 hours in duration, included diarrhea (96.3%), abdominal cramps (90%), nausea (50.6%), weakness (24.7%), and vomiting (13.8%). Eighty-seven employees sought medical attention, 84 of whom were seen in an emergency room. Although a significant difference was not demonstrated in food-specific attack rates, B. cereus was cultured from both rice and chicken items that were served at both meals. Sixty-three employees submitted stools for culture that grew no enteric pathogens, but none were examined for B. cereus. This food-borne outbreak demonstrates: the need for hospital kitchen supervisors to ensure proper handling of food when outside caterers are employed; that significant differences in food-specific attack rates may not be demonstrated in outbreaks, which may be related to several factors; and the importance of notifying microbiology laboratory personnel when B. cereus is a suspect enteric pathogen, since many laboratories do not routinely attempt to identify this organism in stool specimens.

A point source outbreak of Vibrio cholerae O1 El Tor Inaba infections occurred aboard an oil rig south of Port Arthur, Texas, in September 1981. Sixteen crew members had V. cholerae O1 infections as determined by serology or stool specimens; 15 were symptomatic. The high percentage of symptomatic infections was attributed in part to the ingestion of a large number of V. cholerae O1 organisms by susceptible individuals. Symptoms included diarrheal stools (100%), weakness (60%), abdominal cramps (53%), nausea (40%), and vomiting (27%). Only one of the three patients who sought medical attention was diagnosed by his physician as having cholera. Physicians who treat patients who live near or travel to the Gulf Coast should consider cholera in patients with watery stools. If cholera is suspected, laboratories should use thiosulfate-citrate-bile salts-sucrose (TCBS) agar in addition to routine enteric media for processing stool specimens.

Mecamylamine (MCL) has been shown to extinguish nicotine dependence in rats and monkeys. MCL was administered to fourteen nicotine-dependent persons to determine if it may be effective in withdrawing nicotine-dependent humans at doses which have acceptable toxicity. Subjects smoked 20 to 60 cigarettes per day for a mean of 2.4 years, and none had been nicotine abstinent for as much as one day for at least one year. MCL was started in a dose of 5 to 10 mg per day and progressively raised until the subject experienced nicotine blockage and/or toxic effects. During MCL administration, 7 of 14 (50%) totally ceased smoking within the first 11 days of treatment, and an additional 4 (28.6%) subjects reduced cigarette consumption to less than five per day by the end of three weeks. Thirteen of 14 (92.9%) subjects stated that MCL blocks nicotine, reduces nicotine craving, and "works." At least some minor side-effects of MCL were observed in every subject. The most intolerable side-effects were constipation, urinary retention, abdominal cramps, and weakness, and these were responsible for drop-out of 5 (35.7%) subjects. Although there is a high prevalence of side-effects, MCL is probably a viable withdrawal treatment for some cases of recalcitrant nicotine dependence.

A total of 611 Schistosoma mansoni infected primary school children from three schools in north-east Ethiopia were treated with praziquantel at 40 mg/kg body weight in a single dose. Pre-treatment, 40.4% had no presenting symptoms and 30-40% had nausea, abdominal cramps and/or bloody-mucoid diarrhoea. None of the pre-treatment symptoms was related to nutritional status, intensity of S. mansoni egg excretion, or to the presence of other concomitant intestinal parasitic infections. During the first 4-6 h post-treatment observation period, 90 (14.7%) children self-presented with severe gastro-intestinal symptoms. Children who self-presented with severe symptoms had a higher mean age and mean S. mansoni egg excretion compared with children who did not self-present. The following day a total of 529 (86.6%) children, including all who self-presented during the first 4-6 h post-treatment, reported for clinical check-up and were subjected to a structured questionnaire interview on symptoms they had experienced over the time lapse following treatment. Among these, 91.5% reported one or more treatment related symptoms which were at times severe. Abdominal cramps (86.9%), diarrhoea with blood and/or mucus (49.5%), dizziness (31.2%) and vomiting (24.9%) were the most common treatment related symptoms. Skin rash with oedema were observed in four cases. Among treatment related symptoms, the combination of abdominal cramps with vomiting, bloody diarrhoea, vomiting alone and general weakness were significantly higher among the malnourished. A proportion of these symptoms increased with increasing categories of S. mansoni egg excretion before and after adjusting for nutritional status and concurrent intestinal parasitic infections. Overall, the cure rate of praziquantel, among 541 children who had stool examination 5 weeks after treatment was 83.2% and this rate decreased with increasing pre-treatment egg counts. In conclusion, most of the treatment related symptoms were mild. However, some of the objective symptoms were at times severe and may reduce drug compliance in primary health care based population chemotherapy.
