Helicobacter pylori is accepted as an important factor in the pathogenesis of peptic ulcer disease. Infection is probably most commonly acquired in early life but there is still limited information on the prevalence or symptomatology of H. pylori infection in childhood. The aim of the present study was to establish the prevalence of H. pylori infection in a large sample of urban school children and to determine its relationship, if any, to a history of recurrent abdominal pain. Using a commercial ELISA significant levels of anti-H. pylori IgG antibody were detected in 107/640 (16.7%) of school children (M, 383; F, 257; mean age 9.15 years, range 4-13). No relationship was demonstrated between H. pylori seropositivity and a personal or family history of recurrent abdominal pain or the nature of the pain.

The aim of our study was to analyze the clinical course and outcome of acute renal failure (ARF) in patients with hemorrhagic fever with renal syndrome (HFRS). From 1983 to 1995, we treated 33 patients (27 males, 6 females) aged from 16 to 71 years. Half of patients were connected with work at a farm or in a forest. The disease was confirmed serologically with indirect immunofluorescence test (IFT) and enzyme-linked immunosorbent assay (ELISA). In 18 patients percutaneous kidney needle biopsies were analyzed. In 85% of the cases, the disease broke out from June to October. The most frequently expressed clinical signs and symptoms were fever, nausea/vomiting, headache, backache, abdominal pain, myalgia, diarrhea, conjunctival injection, and hemorrhages. Four patients had concomitant pancreatitis. In 25 patients, oliguria was present, and transient hemodialysis treatment was needed in 19 patients. Infection with Hantaan virus was established in 20 patients and with Puumala virus in 13 patients. At renal biopsy, acute interstitial nephritis accompanied with hemorrhages and necrosis was found, and at a later biopsy there were also signs of interstitial fibrosis. All patients were cured, but renal function was not completely recovered in some. We conclude that ARF is a serious complication in patients with HFRS. Although not lethal in our group of patients, many of them showed severe signs and symptoms of illness. Transient hemodialysis was necessary in two-thirds of the patients. Some degree of functional defects and morphological changes might persist.

Coccidial parasites of the genus Isospora cause intestinal disease in several mammalian host species. These protozoal parasites have asexual and sexual stages within intestinal cells of their hosts and produce an environmentally resistant cyst stage, the oocyst. Infections are acquired by the ingestion of infective (sporulated) oocysts in contaminated food or water. Some species of mammalian Isospora have evolved the ability to use paratenic (transport) hosts. In these cases, infections can be acquired by ingestion of an infected paratenic host. Human intestinal isosporiasis is caused by Isospora belli. Symptoms of I. belli infection in immunocompetent patients include diarrhea, steatorrhea, headache, fever, malaise, abdominal pain, vomiting, dehydration, and weight loss, blood is not usually present in the feces. The disease is often chronic, with parasites present in the feces or biopsy specimens for several months to years. Recurrences are common, Symptoms are more severe in AIDS patients, with the diarrhea being more watery. Extraintestinal stages of I. belli have been observed in AIDS patients but not immunocompetent patients. Treatment of I. belli infection with trimethoprim-sulfamethoxazole usually results in a rapid clinical response. Maintenance treatment with trimethoprim-sulfamethoxazole is needed because relapses often occur once treatment is stopped.

Four hundred children between the ages of 1 month and 14 years with the complaint of diarrhea were studied to assess Campylobacter jejuni isolation rates in childhood acute gastroenteritis in Turkey and to clarify clinical presentations of C. jejuni enteritis. C. jejuni was found to be the second most common isolate with a rate of 8.3%, the first being Shigella strains. The highest isolation rate was in the 6 to 14-year age range at 12%. The most frequent symptoms in patients with C. jejuni enteritis were abdominal pain (51.5%), vomiting (36.4%) and fever (30.3%). Stool examination revealed bloody mucous stool in 51.5% of the patients, and erythrocytes and/or leucocytes were detected in 42.4%. Only 12.1% of the patients with C. jejuni enteritis were hospitalized in this study.

The clinical and epidemiologic aspects of infection with Ascaris lumbricoides were studied in a random stratified sample of the population of the subdistrict of Cavacos, municipality of Alterosa (Minas Gerais, Brazil). The effect of mass treatment with a single dose of albendazole on the prevalence and intensity of infection was also studied six months later in the same population. During the first phase of the study, a questionnaire was applied to 248 individuals to obtain information about the socioeconomic, sanitary and clinical conditions of the population surveyed. A total of 230 fecal samples were also examined by the Kato-Katz technique in order to determine the intensity of A. lumbricoides infection. Two hundred and two individuals were simultaneously submitted to blood counts and 70 children aged 12 years or less were evaluated for nutritional status. The presence of A. lumbricoides and other helminth eggs was also determined in 22 soil samples collected in the urban zone of Cavacos. Infection with enteroparasitic helminths was detected in 29.1% of the sample, with a predominance of A. lumbricoides (23.9%). Parasitism and/or intensity of A. lumbricoides infection were significantly correlated with age range (15 years or less), social class, sanitary and living conditions (water, sewage and domiciliary area per person), and presence of abdominal pain. However, these parameters were not correlated with nutritional status or hematocrit levels. During the second phase of the study, a slight but not statistically significant decrease in the prevalence of A. lumbricoides infection was detected after treatment with albendazole. However, an important and significant reduction in the amount of A. lumbricoides eggs eliminated through the feces was detected, indicating that the intensity of A. lumbricoides infection was lower in all the age ranges of the Cavacos population, especially among younger individuals, even six months after administration of the anthelminthic agent.

Denmark has in recent years experienced a rise in the number of bacterial gastrointestinal infections. We have reviewed patients hospitalized with culture confirmed bacterial gastroenteritis in Roskilde County during 1991-1993. Two hundred and seven patients were included, 68 were children (< 15 years). The microorganism isolated was Salmonella in 61% of the cases. Campylobacter in 20% and Yersinia enterocolitica in 13%. Ninety-three percent of the patients had diarrhoea, 74% had fever (> 38 degrees C), and 66% abdominal pain. Blood in the stools was most frequent in patients infected with Campylobacter. Leucocytosis was rare. Twenty-four patients had bacteraemia. Reactive arthritis occurred in 4.8%. Three patients died, all infected with zoonotic Salmonella types. Three stool cultures were made for 115 patients, and all three cultures were positive in 73% of these patients. Bacterial gastroenteritis requiring hospitalization in Roskilde County, 1991-1993 affected mainly children and young adults. Infections due to zoonotic Salmonella types were more severe than Campylobacter and Yersinia enterocolitica gastroenteritis. It seems necessary to collect at least three stool cultures to secure a bacteriological diagnosis.

Forty-three cases of diabetic ketosis were analysed to determine the mode of presentation, treatment modalities and outcome. Among these cases 62.8% were non-insulin dependent diabetes mellitus (NIDDM) patients and 37.2% belonged to the insulin dependent diabetes mellitus (IDDM) group. Six patients had blood glucose levels of more than 250 mg/dl but less than 300 mg/dl who were grouped separately for analysis under the term "euglycaemic diabetic ketoacidosis (EGDK)". Infection was the commonest precipitating factor in diabetic ketosis in all groups. Abdominal pain and vomiting occurred with NIDDM and EGDK cases. Drowsiness was common and coma was rare. Acute myocardial infarction (MI) and pulmonary oedema occurred with NIDDM cases. Shock, acidosis, acquired respiratory distress syndrome (ARDS) and mucor mycosis were seen with IDDM cases. Mortality was 7 out of 43(16.3%). Saline requirement was lower in NIDDM and EGDK cases. Intensive insulin therapy with hourly intravenous doses were needed for IDDM cases while majority of NIDDM cases could be managed with 6 hourly doses of insulin given subcutaneously or intramuscularly.

Human echinostomiasis, endemic to southeast Asia and the Far East, is a food-borne, intestinal, zoonotic parasitosis attributed to at least 16 species of digenean trematodes transmitted by snails. Two separate life cycles of echinostomes, human and sylvatic, efficiently operate in endemic areas. Clinical symptoms of echinostomiasis include abdominal pain, violent watery diarrhea, and anorexia. The disease occurs focally and transmission is linked to fresh or brackish water habitats. Infections are associated with common sociocultural practices of eating raw or insufficiently cooked mollusks, fish, crustaceans, and amphibians, promiscuous defecation, and the use of night soil (human excrement collected from latrines) for fertilization of fish ponds. The prevalence of infection ranges from 44% in the Philippines to 5% in mainland China, and from 50% in northern Thailand to 9% in Korea. Although the patterns of other food-borne trematodiases have changed in Asia following changes in habits, cultural practices, health education, industrialization, and environmental alteration, human echinostomiasis remains a health problem. The disease is most prevalent in remote rural places among low-wage earners and in women of child bearing age. Echinostomiasis is aggravated by socioeconomic factors such as poverty, malnutrition, an explosively growing free-food market, a lack of supervised food inspection, poor or insufficient sanitation, other helminthiases, and declining economic conditions. Furthermore, World Health Organization control programs implemented for other food-borne helminthiases and sustained in endemic areas are not fully successful for echinostomiasis because these parasites display extremely broad specificity for the second intermediate host and are capable of completing the life cycle without involvement of the human host.

In May 1994 an outbreak of vomiting and diarrhoea occurred in a 28-bed long-stay ward for the mentally infirm. The predominant symptoms were vomiting, diarrhoea, malaise and abdominal pain lasting for approximately 12 h in most cases. The attack rate was 62% (13/21) for patients and 46% (16/35) for staff members. Infection control measures were implemented (containment of infectious individuals, hand hygiene among staff and environmental decontamination) and the ward was closed to admissions. Affected staff were excluded from contact with patients and their food until asymptomatic for 72 h. The outbreak lasted for 17 days. Faecal samples from nine symptomatic persons were negative for bacterial enteric pathogens, Giardia, Cryptosporidium and group A rotavirus. Electron microscopy of 12 faecal samples and one sample of vomitus revealed small round structured virus (SRSV) particles in one faecal sample. A further 30 faecal samples and seven vomitus samples were tested by reverse transcription polymerase chain reaction (RT-PCR) for SRSV of which 12 (40%) and 1 (14%) were positive respectively. Twenty-eight throat swabs from symptomatic and asymptomatic patients were collected, three (9.5%) of which were positive for SRSV by RT-PCR. Thirty-six environmental swabs were collected on the affected ward, and 11 (30%) were positive by RT-PCR. Positive swabs were from lockers, curtains and commodes and confined to the immediate environment of symptomatic patients. The distribution of contamination supports the rationale of cohorting sick patients.
