Gut lavage by ingestion of large volumes of electrolyte solutions has been shown to be an effective method of cleansing the colon before colonoscopy, barium enema or surgery. Absorption of water and electrolytes, which might be hazardous to patients who are unable to readily excrete an additional sodium and/or water load, is prevented by addition of non-absorbable substances to the solutions, but systematic studies are lacking. We have evaluated the influence of three solutions for gut lavage with different electrolyte composition (sodium concentration 67 mmol/l and 125 mmol/l) and addition of different non-absorbable substances (mannitol and polyethylene glycol [PEG]) on water and electrolyte homeostasis and subjective tolerance, both in healthy volunteers and in patients before endoscopy of the colon. In a randomized, blind study 6 liters of the three solutions were administered via a nasogastric tube to 6 healthy volunteers during 4 hours (i.e. 1.5 l/h). Body weight, serum concentrations of sodium, potassium and of phosphate were measured before infusion of the solution and after the last rhythmic rectal effluent. No significant changes were observed in any of the studied parameters and the incidence of side effects (nausea, abdominal cramps) was comparable. In an additional clinical double blind study, 26 patients before diagnostic colonoscopy were asked to drink 4 liters of the gut lavage solutions as quickly as possible in order to clean out the colon. The time for drinking was significantly shorter in patients using the mannitol and low sodium solution (204 +/- 70 minutes) than in patients drinking the solution with polyethylene glycol and a high sodium concentration (387 +/- 137 minutes). There was a tendency to a longer drinking period in patients ingesting the solution with polyethylene glycol and low sodium (306 +/- 106 minutes). Thus, the acceptance for solutions containing polyethylenglycol and high sodium concentration is reduced because of low palatibility. Again no influence on serum electrolyte concentrations or body weight could be observed in any patient, the spectrum of side effects was similar and the cleansing effect of all three solutions was adequate. In conclusion solutions for gut lavage containing a balanced electrolyte concentration and nonresorbable substances such as mannitol or polythylenglycol are equivalent. However, solutions containing mannitol and a low sodium concentration are better tolerated by the patients but the use of mannitol is limited because of the risk of releasing explosive gases during interventional endoscopy. To enhance the acceptance and palatibility of solutions for gut lavage containing polethylenglycol the addition of flavoured substances is recommended.

On 24 February 1995, six U.S. soldiers serving with the Multinational Force in Haiti became ill after eating a locally caught fish identified as the greater amberjack Seriola dumerili. The victims presented with nausea, vomiting, watery diarrhea and abdominal cramps 5-8 hr after consumption. Also present in some victims were numbness in the extremities or perioral region, bradycardia and scalp paresthesia. Patients were treated with i.v. hydration therapy and antiemetics. All recovered without sequelae over the course of 1-3 months. A portion of the cooked fish was obtained for analysis. A semipurified lipid extract was prepared according to standard methods and analyzed for the presence of Na+ channel site 5 binding activity using a brevetoxin receptor binding assay. By this assay, the fish sample contained the equivalent of approximately 20 ng Caribbean ciguatoxin/g flesh. The presence of the major Caribbean ciguatoxin (C-CTX-1) was confirmed by liquid chromatography-mass spectrometry. Using the receptor binding assay to monitor activity in TSK and PRP-1 column fractions, two minor toxins were detected in addition to C-CTX-1. One of these minor toxins was more polar, and the other less polar, than C-CTX-1. These data provide firm evidence that a family of C-CTX-1 is responsible for ciguatera in the Caribbean.

In a survey examining the causes of travellers' diarrhoea treated in Tokyo between July 1986 and December 1995, Aeromonas species were isolated from 1265 (5.5%) of 23,215 travellers returning from developing countries. Aeromonas species were the fourth most frequent enteropathogen isolated, following enterotoxigenic E. coli (8.5%), Salmonella spp. (7.6%) and Plesiomonas shigelloides (5.6%). Aeromonas species were found in 1191 (5.6%) of 21,257 patients with diarrhoea and in 74 (3.8%) of 1958 healthy individuals without diarrhoea. Mixed infection was observed in 512 (40.5%) cases. No significant difference in the prevalence of Aeromonas by year, season, age distributions, or sex was observed, but a slight difference was noted depending on the country where the travellers visited. Of the 1265 Aeromonas isolates, 893 strains (70.6%) were A. veronii biovar sobria, 330 (26.1%) were A. hydrophila, and 42 (3.3%) were A. caviae. The clinical symptoms of patients from whom Aeromonas species was isolated as the only potential enteric pathogen were almost similar, which were watery diarrhoea (about 60%), abdominal cramps (43%), fever (around 15%), and nausea or vomiting (13%). Although the severity of illness was milder than that of enterotoxigenic E. coli alone, these data suggest that Aeromonas species are important enteric pathogens in travellers' diarrhoea.

This article summarizes two investigations that examine the health effects of prolonged exposure to copper-contaminated drinking water. The first study was initiated after elevated copper levels were detected in several homes that were either newly constructed or recently remodeled. All of these homes were served by the same municipal water supplier. The second case involved illnesses and water-quality problems that were reported by several residents of a mobile home park shortly after a new water distribution system was installed. Findings from these investigations suggest that copper-contaminated drinking water may be a fairly common cause of nausea, diarrhea, abdominal cramps, and headaches-especially among residents of new or recently-remodeled homes, and in areas where water supplies are naturally corrosive.

Symptoms consistent with an outbreak of cryptosporidiosis (diarrhea, vomiting, nausea, and abdominal cramps) occurred on a U.S. Coast Guard cutter within 0-18 days after the cutter filled its tanks with Milwaukee, Wisconsin city water in March 1993. At three-weeks postdocking (PD), the suspected water was removed, and serum samples and stool specimens were collected from 47 of the 58 crew members, as well as questionnaire data on their water consumption and symptoms aboard the cutter. At 10-weeks PD and/or at 28-weeks PD, additional serum specimens were collected. Intensitometric data from enzyme-linked immunoelectrotransfer blot (EITB) were obtained on IgA responses to a 17-kD antigen group, IgM responses to a 27-kD antigen group, and IgG responses to 27-, 17-, and 15-kD antigen groups extracted from oocysts. In addition, IgG responses to crude oocyst antigens were obtained by ELISA. Based on reported symptoms, EITB results, and stool examination, the crew members were classified as confirmed (10), probable (10), suspected (22), and noncases (16). Of the 10 confirmed cases (all symptomatic) and the 10 probable cases (eight symptomatic) whose stools were positive and negative, respectively, for Cryptosporidium oocysts by microscopy, all showed changes in EITB intensities to the antigen groups and were considered EITB positive. The remaining 38 crew members, 22 suspected cases (all symptomatic), and 16 noncases (all asymptomatic), if tested, had negative stool examinations and were considered EITB negative. Of the 10 confirmed cases, only four showed a significant change in IgG responses (P < 0.05) between three-weeks PD and follow-up serum specimens by ELISA. Crew members considered confirmed cases consumed significantly more water (P < or = 0.005) aboard the cutter than noncases. Crew members considered EITB positive consumed more water (P < or = 0.04) than crew members considered EITB negative while there was no significant difference in water consumption (P > or = 0.19) between crew members considered ELISA positive and ELISA negative. Using the EITB, the observation of changes in intensity of IgA responses to the 17-kD antigen group, IgM responses to the 27-kD antigen group, and IgG responses to the 27- 17-, and 15-kD antigen groups from C. parvum oocysts between acute and convalescent serum specimens appears useful for immunodiagnosis of Cryptosporidium infection and for prospective epidemiologic studies designed to monitor infection risk.

During the past 4 years, several case reports have been published on the withdrawal syndrome which may be observed after acute interruption of a treatment with selective serotonin reuptake inhibiting antidepressants (SSRI). Paroxetine is the most frequently cited antidepressant in the literature, whereas fluoxetine is the less frequently cited of this type of drugs. The withdrawal symptoms appear a few days after stopping treatment or after a decrease of the dose. The typical symptoms are of the gastro-intestinal type, such as loss of appetite, nausea, vomiting, diarrhea and abdominal cramps. Other symptoms are sensation of instability, vertigo, dizziness, headache, malaise, muscular pains, asthenia, as well as a syndrome of pseudo-influenza. Brief electric shocks throughout the body, which last one or two seconds, have also been reported. A case is reported in detail by the authors, who observed some of these symptoms in a patient after stopping his treatment with paroxetine. This withdrawal syndrome may be due to a rebound phenomenon of the serotonergic systems after interruption of the treatment with SSRIs. It is, therefore, recommended that treatment with SSRIs is progressively stopped over a period of several weeks.

During 1992 and 1993 the Wisconsin Division of Health investigated five cases in which copper-contaminated drinking water was suspected of causing gastrointestinal upsets. Each of these case studies was conducted after our office was notified of high copper levels in drinking water or notified of unexplained illnesses. Our findings suggest that drinking water that contains copper at levels above the federal action limit of 1.3 mg/l may be a relatively common cause of diarrhea, abdominal cramps, and nausea. These symptoms occurred most frequently in infants and young children and among resident of newly constructed or renovated homes.

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.

The macrolides are a well established group of antibacterials frequently used in general practice. The most frequently used macrolides in paediatric patients are erythromycin, a naturally occurring compound, and clarithromycin and azithromycin, recently developed macrolides. Overall adverse effect rates of 7 to 26% for erythromycin, 14 to 26% for clarithromycin, and 6 to 27% for azithromycin have been described in children. Adverse gastrointestinal effects, including nausea, vomiting, diarrhoea and abdominal cramps, are the most common problems in children. Allergic reactions, hepatotoxicity, ototoxicity and adverse effects involving the central and peripheral nervous systems have also been observed in children. Stevens-Johnson, Schonlein-Henoch and Churg-Strauss syndromes have been rarely described in children. Treatment-related laboratory abnormalities have been recorded in 2 to 4% of erythromycin- and in 0 to 1% of both clarithromycin- and azithromycin-treated children. Elevation in liver function tests was the most common abnormality cited. Increased macrolide use in children in recent years has resulted in a growing potential for drug interactions between them and other pharmacologically active agents via the inhibition of cytochrome P450 (CYP) microsomal enzymes. Drug interactions with theophylline, cyclosporin, carbamazepine, terfenadine and warfarin limit erythromycin use. Clarithromycin is a weak inducer of CYP and exhibits fewer drug-drug interactions than erythromycin. However, its use with theophylline, carbamazepine and terfenadine is contraindicated. In contrast, no significant interactions have been reported with azithromycin to date. Macrolides have been proven to be well tolerated in the treatment of upper and lower respiratory tract infections, skin and soft tissue infections, and also in less frequent infections occurring in paediatric patients. In addition, clarithromycin and azithromycin have shown good tolerability profiles in immunocompromised paediatric patients. In conclusion, macrolides antibacterials have proven to be well tolerated in paediatric patients. Although the incidence of adverse effects is similar with the use of erythromycin and the newer macrolides, drug interactions occur significantly less when clarithromycin or azithromycin are administered.

We compared the clinical and microbiological efficacy of dirithromycin with that of azithromycin in outpatients with acute bacterial exacerbations of chronic bronchitis who could be graded into stage III according to Ball's system of stratification. A total of 80 patients was studied. Of these, 40 were treated with dirithromycin as a once-daily dose of 500 mg for 5 days, and 40 with azithromycin as a once-daily dose of 500 mg for 3 days. At post-therapy, treatment success (cure or improvement) was achieved in 36 out of 40 (90%) patients receiving dirithromycin compared with 37 out of 40 (92.5%) in the azithromycin group. At the late post-therapy visit, 34 out of 36 (94.4%) dirithromycin-treated patients were cured as were 33 of 37 (89.2%) azithromycin-treated patients. A small proportion of patients treated with dirithromycin (10%) or with azithromycin (12.5%) suffered mild side effects. Gastrointestinal disorders, including abdominal cramps, nausea, or diarrhea, were common adverse effects. The main pathogens isolated before treatment were Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Eradication rates at the end of treatment were 90% (36 out of 40) for the dirithromycin group and 92.5% (37 out of 40) for the azithromycin group. Persistence of H. influenzae isolates was found in 3 out of 11 (27.3%) patients treated with dirithromycin and in 2 out of 9 (22.2%) who had received azithromycin. At the late post-therapy visit, eradication occurred in 34 out of 36 (94.4%) strains in the dirithromycin group and in 33 out of 37 (89.2%) in the azithromycin group. We conclude that dirithromycin and azithromycin appear to be equally effective in the treatment of acute bacterial exacerbations of chronic bronchitis.
