In an outbreak of gastrointestinal illness caused by consumption of home-grown raw vegetable sprouts contaminated by Bacillus cereus, victims developed symptoms after an incubation period of 6-15 hours. Four persons initially experienced nausea and vomiting, and this was followed in 3 cases by abdominal cramps and diarrhea. Bacteriologic investigation indicated that B. cereus on unsprouted seeds proliferated during germination in a commercially sold seed sprouting kit and reached levels in excess of 10(7) per gram. B. cereus isolated from the incriminated sprouts exhibited enterotoxigenic activity when tested by the ligated rabbit ileal loop technique, the dermal reaction in guinea pigs, and the rabbit skin capillary permeability test. The diversity of symptoms and incubation periods attributed to B. cereus requires analysis for this often overlooked organism whenever food-borne gastroenteritis is suspected.

Of 34 non-bacterial gastroenteritis outbreaks which occurred at day-care centers, kindergartens, elementary and secondary schools in Tokyo during the period from February 1985 to June 1991, 28 outbreaks from which small round structured viruses (SRSV) were detected in the patients' stool specimens by electron microscopy were subjected to an epidemiological investigation. The outbreaks tended to occur frequently in the cold season; twenty-two (79%) of these outbreaks from November through April. Though detailed epidemiological informations was not obtained from all outbreaks, the common source of infection were presumed to be present in many of the outbreaks, judged from the incidence as to time course of patients. Food doubted to be incriminated as transmission vehicles in these outbreaks was served at schools, kindergartens, and lodgings. In some outbreaks, SRSV was detected from stool specimens of food handlers, or they were seroconverted to SRSV, suggesting that food was incriminated as a transmission vehicle. The symptoms of patients differ slightly from age to age: in the age range of 0 to 6 years, vomiting 90%, fever 41% and diarrhea 32%; in the 6 to 12 year-olds, nausea 61%, vomiting 48%, abdominal pain 65%, diarrhea 20% and fever 29%; and in the 12 to 15 year-olds, nausea 69%, vomiting 42%, abdominal pain 60%, diarrhea 30% and fever 34%. The lower the age of patient vomiting was more frequently observed. In these lower age groups, the frequency of nausea and vomiting tended to exceed that of diarrhea.

92 cases of acute gastroenteritis were registered among 256 individuals during an outbreak in a nursing home for the elderly, the majority of patients being between 70 and 90 years of age. Most cases appeared in 4 of the 8 wards; 66% of the inmates of these wards became ill. Characteristic symptoms were initial nausea and vomiting followed by diarrhoea and low fever. A number of patients were severely ill. One patient died. Rotavirus infection was diagnosed by virus detection and/or antibody titre rise during the acute phase of the illness in 13 of 16 patients examined. At the end of the outbreak, high titres of complement-fixing antibodies against rotavirus (greater than or equal to 64) were detected in serum from 21/22 patients convalescing from the disease, as compared to only 5/45 individuals with no signs of disease. It is tentatively suggested that the outbreak became extensive and rather severe because of lowered immunity against rotavirus infection among the elderly.

In July 1981, an outbreak of gastroenteritis occurred at a summer diet camp. Of the 455 campers and staff, 35 per cent developed an illness characterized by abdominal pain, fever, diarrhea, and/or nausea and vomiting. A total of 53 per cent experienced abdominal pain. Seven persons were hospitalized, five of whom had appendectomies. Yersinia enterocolitica serogroup 0:8 was isolated from 37 (54 per cent) of 69 persons examined, including the camp cook and three assistants. An epidemiologic investigation demonstrated that illness was associated with consumption of reconstituted powdered milk and/or chow mein . Y. enterocolitica serogroup 0:8 was subsequently isolated from milk, the milk dispenser, and leftover chow mein . Information obtained during the investigation suggested that the Yersinia had been introduced by a food handler during food-processing procedures.

Nausea and vomiting occur commonly with gastroenteritis caused by parvovirus-like agents. Infection results in histologic injury to the small bowel mucosa, but the gastric mucosa remains unaffected. We have studied gastric emptying of liquids serially in 10 volunteers before and after ingestion of the parvovirus-like agents, Norwalk and Hawaii viruses. The five subjects who developed illness all showed marked delays in gastric emptying, while the five well subjects had no alteration of emptying. Five addition volunteers who developed Norwalk virus gastroenteritis underwent serial studies of gastric secretion of hydrochloric acid, pepsin, and intrinsic factor. No change was detected in either basal or betazole-stimulated secretion of these three substances during the course of illness. The nausea and vomiting accompanying this type of viral gastroenteritis may result from abnormal gastric motor function.

Two outbreaks of gastroenteritis in the UK which occurred nine days apart at Lymington and Southampton hospitals were investigated. The clinical and epidemiological features of both outbreaks were characteristic of small round-structured virus (SRSV) infection with rapid onset of diarrhoea and/or nausea and vomiting and propagation of the outbreaks by secondary spread. SRSV particles were observed by immune electron microscopy (EM) in 60% of faecal samples from both outbreaks and no other pathogens were detected. The index case for the second outbreak was a patient who was admitted with diarrhoea and vomiting after being discharged from Lymington hospital during the first outbreak. The possibility that the two outbreaks were caused by the same strain of SRSV was investigated by the polymerase chain reaction (PCR). New inosine-containing PCR primers were designed to amplify the RNA polymerase region of SRSV cDNA from genetic groups I and II. The PCR using the group II primers achieved a higher detection rate for SRSVs in faecal samples (68% of samples positive from both outbreaks) than immune EM. SRSVs were not detected using the group I primers or using conventional degenerate PCR primers. The nucleotide sequences of PCR amplicons from both outbreaks were identical providing molecular epidemiological evidence for the involvement of a single SRSV strain. Comparison of the RNA polymerase region of this virus with the equivalent regions of genetic group I (69.4-75.0% amino acid identify) and genetic group II (88.9-100% amino acid and 77.1-88.1% nucleotide identity) SRSVs revealed that the causative SRSV was a distinct member of genetic group II.

The clinical efficacy and safety of brodimoprim has been studied by numerous investigators. In the trials reviewed 2291 cases were entered. Of these 2214 were evaluable for efficacy and 2277 for safety. Brodimoprim has been found to exhibit good therapeutic efficacy in upper and lower respiratory tract infections, in bacterial gastroenteritis and in typhoid fever. Response rates in the above indications were reported to be in the range of 85-100% for upper respiratory tract infections, 84-92% for lower respiratory tract infections, 97-100% for bacterial gastroenteritis and 95-100% for enteric fever. In controlled studies these response rates were in the same range as those obtained with standard drugs (ampicillin, amoxicillin, cephalosporins, erythromycin, doxycycline, chloramphenicol). Of the 2277 patients assessable for safety 1429 had received brodimoprim and 848 received a comparative agent. In the brodimoprim group, the overall incidence of clinical adverse events occurring in patients during treatment was 12.7%. The majority of adverse events reported were nausea and vomiting, skin reactions, and CNS reactions. The incidence and pattern of adverse events caused by comparative drugs was similar to those caused by brodimoprim, with the exception of doxycycline which generated fewer clinical adverse events than the other regimens. Brodimoprim in single daily doses may be considered as a highly efficacious and well tolerated antibacterial agent against a broad range of bacterial infections.

The costs for diagnostic workup in the medical emergency room were analyzed for 1000 consecutive patients in the course of a cost analysis program. Next to demographic data, the complaints leading to admission, all diagnostic procedures and tests as well as the final diagnosis were recorded. According to cumulated tariffs of individual services, the total cost for the 1000 patients amounted to Sfr. 303000. Medical, laboratory and technical services each amounted to one third of this sum. The cost of Sfr. 303 per patient compared rather well with those of Sfr. 350 for the average initial consultation at the outpatient clinic. The three symptoms thoracic or abdominal pain and headache covered 50% of the reasons for admission. The five most common diagnoses were: common cold, chest wall tenderness, gastroenteritis, headache and acute upper respiratory tract infection. The most cost-intensive workup was performed for nausea and vomiting and abdominal or thoracic pain. Technical procedures such as chest films and upper panendoscopy were responsible for high costs. Assessment of costs according to symptoms and final diagnosis, respectively, yielded almost identical results. In both cases, minimal and maximal costs varied by a factor of 20 or more.

An outbreak of gastrointestinal illness occurred amongst attendees of a conference lunch in the Hunter area, New South Wales, in October 2001. A distinctive symptom reported by many ill persons was the presence of oily diarrhoea. The Hunter Public Health Unit investigated the outbreak by conducting a telephone interview of the cohort of conference attendees using a standard questionnaire. Twenty persons out of 44 attendees (46%) became ill following the conference. The median incubation period was 2.5 hours (range 1-90 hours). The most common symptoms reported were; diarrhoea (80%)-38 per cent of these reported oily diarrhoea; abdominal cramps (50%); nausea (45%); headache (35%) and vomiting (25%). For analyses, a case was defined as a person who developed oily diarrhea, or diarrhoea within 48 hours, or had at least two other symptoms of gastroenteritis within 6 hours, of the conference lunch. Seventeen persons had symptoms that met the case definition. None of the foods or beverages consumed were significantly associated with illness, however, all cases had consumed fish and none of those who did not eat fish (4 persons) became ill. Moreover, only 'fish' or 'potato chips' could explain a significant proportion of the illness. Analysis of the oil composition of the fish consumed was consistent with the known profile of the species marketed as 'escolar'. Among those who consumed fish the following potential risk factors did not have a significant association with the illness; Body Mass Index, age, health status and the amount of fish consumed. We concluded that consumption of fish within the marketing group escolar can cause severe abdominal cramping, nausea and vomiting, in addition to incontinent diarrhoea.

Beriberi is a disease caused by thiamine (vitamin B1) deficiency. Peripheral and central nerve involvement causes psychosis and memory loss as well as cardiocirculatory effects. We report the case of a 35-year-old woman 8 weeks pregnant who came to the emergency department after bouts of nausea and vomiting over a period of 6 days, with intolerance of both solids and liquids. The initial diagnosis of gastroenteritis was later changed to hyperemesis gravidarum. Episodes of vomiting and nausea continued 48 hours after admission, accompanied by vertical nystagmus, ataxia, and diminished osteotendinous reflexes. Evaluation of the clinical picture confirmed vitamin B1 deficiency, leading to a diagnosis of Wernicke-Korsakoff syndrome. Symptoms improved with thiamine therapy but did not entirely disappear. The patient was admitted for elective cesarean section at 37 weeks' gestation. Examination revealed neurological involvement (horizontal and vertical nystagmus) and general anesthesia was therefore chosen to assure adequate hemodynamic control given the possibility of cardiocirculatory alteration.
