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.

Case I: A middle-age homosexual male developed AIDS with Pneumocystis carinii pneumonia (PCP) and esophageal candidiasis in 1986 during his stay in an European country about five months prior to transfer to Tokyo Metropolitan Komagome Hospital, Tokyo, in 1987. He was also diagnosed as having cryptosporidiosis presenting with mild diarrhea a month following the diagnosis of PCP. Diarrhea was successfully treated with spiramycin. On transfer to Tokyo Metropolitan Komagome Hospital, he was febrile but had no diarrhea. Serum HIV and TPHA were positive and his blood lymphocyte subset T4a was markedly decreased. On the 13th day after transfer to the hospital, watery diarrhea appeared. Cryptosporidium oocysts were detected from the feces taken on the 17th hospital day. The patient died of Escherichia coli septicemia on the 38th hospital day. Autopsy finding yielded Cryptosporidium infection widely spread over the stomach, ileum, bile and pancreatic ducts. Case II: A 31-year-old previously healthy female presented with abrupt onset of mucous stool five times daily. Mucous passage continued on the subsequent days despite administration of loperamide, and the passage increased to 20 times daily with mucous to watery diarrhea associated with mild abdominal cramps and nausea on the 4th day after onset of illness. On the 6th day of illness, she visited Tokyo Metropolitan Komagome Hospital. She denied close contact with pet animals or contact with any person presenting diarrhea. She had no recent history of travelling anywhere outside Tokyo. On examination she was an apparently healthy woman except for a slightly distended abdomen with localized tenderness in the right upper quadrant.(ABSTRACT TRUNCATED AT 250 WORDS)

Prostaglandin analogues, used in the treatment of duodenal and benign gastric ulcer and in the prevention of gastric ulceration caused by non-steroidal anti-inflammatory drugs, are frequently associated with gastrointestinal side effects, particularly diarrhoea and abdominal cramps. We investigated the effects of misoprostol, a prostaglandin E1 derivative, on bowel motility and faecal loss of fat, water and bile acids in relation to its postprandial vs. preprandial administration. Twelve healthy subjects participated in a double-blind crossover study comparing three 5-day courses of therapy with a washout period of 1-2 weeks between courses. Following a Latin Square design, the dosing regimens were (a) 400 micrograms misoprostol b.d. after meals and placebo b.d. before meals; (b) 400 micrograms misoprostol b.d. before meals and placebo b.d. after meals; (c) placebo before and after meals. Orocaecal transit time measured by H2 breath tests following lactulose administration, was shortest during pre-prandial dosing but was also significantly decreased during post-prandial dosing. The overall treatment difference was highly significant (P less than 0.001), and the difference between each pair of treatments was also statistically significant. Whole bowel transit time studied by means of 3H-PEG 4000 determination in stools, was shorter for the two misoprostol regimens but statistical significance was borderline. The number of stools passed per day was similar in the three groups. During both misoprostol dosing periods, stools were less formed and their content of water, fat and bile acids was higher. There was also more urgency, flatulence, abdominal pain and nausea. It is concluded that the gastrointestinal side effects caused by misoprostol are mainly based on an increased orocaecal transit time. The effects are more important when the drug is administered before meals than after meals.

Diarrhea represents the most frequent health problem of Western tourists visiting subtropical and tropical areas. Antibiotic prophylaxis has been suggested by some authors but may not be generally advisable because of adverse drug effects. In the present study we investigated the prophylaxis of traveler's diarrhea using a combination of tannalbuminate and ethacridin-lactate. During a 16-day cruise in Egypt, 77 tourists were assigned to either placebo or prophylactic doses of tannalbuminate (500 mg) and ethacridin-lactate (50 mg), 1 tbl. b.i.d., in a randomized double-blind fashion. The number of bowel movements, consistency of stools, and clinical symptoms like nausea, abdominal cramps, vomiting, and fever were monitored daily. In the placebo group (n = 43) 35 tourists developed diarrhea (81.4%), whereas in the verum group (n = 34) only 18 tourists (52.9%) had diarrhea (p less than 0.0125). In the travelers receiving verum and developing diarrhea the clinical symptoms were less pronounced than in the placebo group. These results demonstrate that the events of traveler's diarrhea may be reduced; moreover, symptoms are attenuated by medical prophylaxis with tannalbuminate and ethacridin-lactate.

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.

Nursing management of second trimester abortion by PGE2 suppository after cervical dilatation with laminaria or Lamicel focuses on monitoring and treating side effects, managing pain, and supporting the patient emotionally. Mean abortion time by this method is 15-17 hours, within 24 hours in 80% of women. The side effects expected from PGs are nausea, vomiting, abdominal cramps, and diarrhea. Premedication with transdermal scopolamine, and ancillary methods such as giving ice chips, airing the room, keeping the patient clean are helpful. Acetaminophen is given orally or rectally for fever, headache, or chills. A beta-adrenergic tocolytic drug such as ritodrine HC1 is given if uterine contractions become tetanic, contractions 2-3 per minute or lasting longer than 6-90 seconds, detected by palpation. This drug must be used with caution in patients with asthma. Pain management in midtrimester abortion depends solely on the woman's comfort. Meperidine, morphine, epidural anesthesia with bupivacaine, lidocaine or morphine SO4, or patient-controlled anesthesia may be used. The nurse should monitor side effects such as hypotension, allergic responses, arrhythmias, and inability to void. Midtrimester abortion is often a stress-filled experience, since women may be ambivalent upon learning of fetal abnormalities. The women should be monitored after delivery to ensure that her uterus remains contracted, and assisted if surgical removal of retained products is necessary. Patients teaching for discharge, including medication to prevent lactation, is described. A care plan is suggested for assisting the family with bereavement, based on that used in case of stillbirth or neonatal deaths.

Hunger and satiety appear to reflect the postabsorptive and absorptive phases of caloric homeostasis, respectively. However, only some of the signals that inhibit food intake can be related to caloric homeostasis. For example, decreases in food intake also are observed after administration of nauseogenic chemical agents, treatment with cholecystokinin (CCK), or dehydration. In each case, inhibition of food intake is correlated with induced decreases in gastric motility and increases in secretion of pituitary oxytocin in rats; in primates, including humans, vasopressin but not oxytocin is secreted. In contrast, meal-induced satiety increases gastric contractions and has little or no effect on neurohypophyseal hormone secretion in rats or human subjects. Nauseogenic toxins, CCK, and dehydration stimulate very different subjective states from satiety: LiCl elicits abdominal cramps, nausea, and vomiting, as does exogenous CCK in high doses, whereas dehydration elicits thirst. Thus, inhibition of eating may not be associated with satiety or reflect changes in caloric flux; noncaloric controls of food intake exist and may be accompanied by distinctive increases in neurohypophyseal hormone secretion and loss of gastric function.

In June 1983, an outbreak of waterborne giardiasis occurred in a group of 93 university students and faculty participating in a geology field course in Colorado. All cases occurred in one subgroup of persons who were heavily exposed to untreated stream water on a field trip, and the risk of illness was strongly related to the amount of untreated stream water consumed. The median incubation period from a brief exposure to the first symptom was 7 days. The authors compared symptoms and stool sample results among 31 Giardia-positive persons in the exposed group and 36 Giardia-negative participants in an unexposed group to assess several case definitions for acute giardiasis. Diarrhea, abdominal cramps, flatulence, foul-smelling stools, nausea, excessive tiredness, bloating, anorexia, and chills were each significantly more common in the first group than in the second. A giardiasis case definition of 5 days or more of diarrhea--the definition used in many epidemiologic studies of giardiasis--had a specificity of 100 percent but a sensitivity of only 32.2 percent compared with a definition based on results of stool examinations. When a case was defined as an illness lasting 7 days or more, with a combination of two or more of six symptoms (diarrhea, flatulence, foul-smelling stools, nausea, abdominal cramps, and excessive tiredness), sensitivity rose to 73 percent, with a specificity of 88 percent. Such a case definition may be an improvement over that of 5 days of diarrhea, especially in outbreaks where there is good laboratory documentation that Giardia is the etiologic agent. The definition should be validated in other outbreaks and in situations where giardiasis must be distinguished from gastrointestinal disease caused by other agents.

This is the first report of a phase I study with n-IL 2. N-IL 2 shows a higher biological activity and different immunomodulatory effects compared to recombinant IL 2. 14 patients (9 male, 5 female) entered our phase I study with continuous i.v. n-IL 2 with a median age of 40 years (range 4-65), including 4 children. The study design was a dose rising continuous iv infusion over 5 days with a starting dose of 1 x 10(6) U n-IL 2 up to 6 x 10(6) n-IL 2 over 24 h. In 2 of 16 regimen with n IL-2 there was a dose reduction and in 6 there was an interruption necessary. In 2 patients there was only a dose reduction necessary because of thrombocytopenia and hypotension. In 6 patients n-IL 2 had to break the continuous infusion. Reasons were an increasing BUN, respiratory insufficiency, thrombocytopenia, neurological symptoms and increasing liver enzymes. The 4 children developed an other side effect profile with edema of the face, abdominal cramps and thrombocytopenia. During the study no intensive care was necessary. The most common side effects were erythema, fever, nausea, dyspnea and hypotension. There was no complete remission, 21.5% of the patients had a partial remission, 7% showed no change and 71.5% had a progression. There were no significant differences in toxicity and response was comparable to studies using continuous r IL-2.

HP 029 (1,2,3,4-tetrahydro-9-aminoacridin-1-oL-maleate), an oral anticholinesterase, enhances memory in rodents and may be useful in treating Alzheimer's disease (AD). To assess adverse events in relation to dosage and plasma drug levels, 24 hospitalized AD subjects were randomly assigned to receive placebo or HP 029 for 10 days in a double-blind, sequential escalation study. Maximum daily dosages were 450 mg (group 1), 300 mg (group 2), and 225 mg (group 3), divided into three doses per day. The group 1 trial was discontinued on day 5 because one subject, 6 hours following the second of three scheduled 150-mg doses, had a tonic seizure after protracted vomiting and hyperventilation; adverse events in other patients included nausea, vomiting, abdominal cramps, diarrhea, dizziness, and syncope. Adverse events were generally less severe in group 2, but only two of six HP 029 subjects could complete the trial at 300 mg/day. All group 3 subjects completed the trial at 225 mg/day with drug related, mild adverse events (nausea, vomiting, lacrimation, rhinorrhea) in only two subjects. Although mean plasma drug levels were related to adverse events across dosage groups, they did not adequately predict the occurrence or severity of adverse events in individual subjects. The 225 mg/day dose appears to be safe for use in multicenter outpatient trials of HP 029 efficacy in AD. Further patient studies are ongoing to determine the relation of specific subject characteristics to the metabolic profile of HP 029 and biological response.
