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.

The authors observed a patient who worked in a farm and suffered an organophosphate intoxication (trichlorfon). The immediate effect was manifested by vomiting and abdominal cramps. Three months later he presented a distal symmetric sensorimotor (predominantly motor) neuropathy with distal muscle atrophy. Electromyography has revealed denervation changes in every muscle studied and the sensory and motor nerve conduction was slowed in arms and legs. The sural nerve biopsy specimen studied by light microscopy with semi-thin section and teased fiber preparation showed axonal degeneration. The ultrastructural studies of the axonal alterations consisted of degeneration of the neurofilaments and the neurotubules with granular appearance of the axoplasm.

In Canada in late 1987 there was an outbreak of an acute illness characterized by gastrointestinal symptoms and unusual neurologic abnormalities among persons who had eaten cultivated mussels. Health departments in Canada solicited reports of this newly recognized illness. A case was defined as the occurrence of gastrointestinal symptoms within 24 hours or of neurologic symptoms within 48 hours of the ingestion of mussels. From the more than 250 reports received, 107 patients met the case definition. The most common symptoms were vomiting (in 76 percent of the patients), abdominal cramps (50 percent), diarrhea (42 percent), headache, often described as incapacitating (43 percent), and loss of short-term memory (25 percent). Nineteen patients were hospitalized, of whom 12 required intensive care because of seizures, coma, profuse respiratory secretions, or unstable blood pressure. Male sex and increasing age were associated independently with the risks of hospitalization and memory loss. Three patients died. Mussels associated with this illness were traced to cultivation beds in three river estuaries on the eastern coast of Prince Edward Island. Domoic acid, which can act as an excitatory neurotransmitter, was identified in mussels left uneaten by the patients and in mussels sampled from these estuaries. The source of the domoic acid appears to have been a form of marine vegetation, Nitzschia pungens, also identified in these waters in late 1987. The contaminated mussels from Prince Edward Island were removed from the market, and no new cases have occurred since December 1987. We conclude that the cause of this outbreak of a novel and severe intoxication was the ingestion of mussels contaminated by domoic acid, a potent excitatory neurotransmitter.

Whole bowel irrigation (WBI) was performed in 60 children aged two to 16 yrs (mean 5.1 +/- 0.5 yrs) in preparation for surgery (n: 59) and rectoscopy (n: 1). Isotonic saline (n: 43) and lactated Ringer's solutions (n: 17) were infused for irrigation. Vital signs remained stable during the procedure. Negligible electrolytic alterations were encountered. In general, WBI was well tolerated by all the patients. Two (3.3%) patients had abdominal cramps, vomiting was observed in nine (15%) and edema developed in one (16%). The results of the preparation were assessed as satisfactory in 45 cases (75%), adequate in 10 cases (16.6%) and poor in 5 cases (8.3%). Diarrhea, as a complication of saline, has not been reported previously in the literature, but was observed in 32 of our cases (74.4%), and lasted 2-5 days (mean 3.38 +/- 0.7 days) after irrigation. In addition, it is noteworthy that bile-stained intraluminal clear fluid was seen only in the patients who had been irrigated with lactated Ringer's solution. Our research related to this observation is continuing.

In a two year study carried out by 16 public health laboratories in England and Wales 62,421 patients with presumed infective diarrhoea were investigated. Cryptosporidium infection was identified in 2% (1295), ranging from 0.5% to 3.9% among laboratories. The positivity rate for cryptosporidium was highest in 1-4 year olds, and in children cryptosporidium was the second commonest pathogen after campylobacter. Illness was usually limited to abdominal cramps and watery diarrhoea with six motions/24 hours at worst and lasting seven days. Fewer than half the patients reported fever or vomiting. More severe illness with fever, abdominal cramps, vomiting, and watery diarrhoea of frequency greater than five motions in 24 hours was reported by only a tenth of cases but with a significantly increased prevalence in young adult males. One hundred and fifty five patients (12%) probably acquired their infection abroad; 102 (9%) of patients who acquired their infection at home reported drinking raw milk in the month before onset, and 253 (22%) reported close contact with farm animals. Most laboratories experienced sudden infrequent increases in incidence in the community, only one of which was attributed to a recognised outbreak, which occurred in a nursery. Cryptosporidium should be routinely sought by laboratories investigating acute infectious diarrhoea, especially in children; up to a quarter of cases may be directly zoonotic, and the remainder may be due to person to person spread and waterborne infection.

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.

We report a case of nearly fatal cardiovascular collapse attributable to an idiopathic anaphylactic reaction in a 76-year-old man. The event began with gastrointestinal symptoms of abdominal cramps, diarrhea, nausea, and vomiting as manifestations of IA. The patient subsequently progressed to develop urticaria, flushing, cardiovascular symptoms of chest pain, hypotension, and eventually cardiovascular collapse and myocardial infarction over a five-hour interval. This case emphasizes that the potential for life-threatening cardiovascular events from IA exists in patients without previously defined cardiac risk factors.
