In April 1991, an outbreak of acute gastroenteritis due to group C rotavirus occurred at an elementary school in Tokyo. Fifty-one (13%) of 393 students became ill. The main clinical symptoms were diarrhea (100%), abdominal pain (68%) and vomiting (56%). No enteropathogenic bacteria were found in the fecal specimens. However, the virus particles morphologically indistinguishable from conventional rotavirus were detected in 6 of 11 fecal specimens by electron microscopy. Immune electron microscopy showed that these virions aggregated with anti-group C rotavirus serum. The RNA pattern of the virus particles involved in this outbreak showed a pattern similar to that of typical group C rotavirus on polyacrylamide gel electrophoresis.

During the 1989 Christmas holiday period, a large outbreak of gastroenteritis occurred among persons staying at a caravan park in southern New South Wales. Review of local hospital records found that 77 per cent of patients presenting with infective diarrhoea between 29 December and 3 January had stayed at the caravan park. In a retrospective cohort study we compared rates of illness among caravan park patrons exposed to different water sources. Stools were tested for pathogens and convalescent sera for viral antibodies. Rain and reticulated river water sampled from the caravan park were tested for bacteria and viruses. Of 351 persons interviewed at the caravan park, 305 (87 per cent) reported an illness characterised by diarrhoea, vomiting and abdominal pain. Of 196 persons who used reticulated river water for drinking or ablutions, 175 (89 per cent) became ill compared with 47 of 72 persons (65 per cent) who did not use this water (relative risk 1.4, 95 per cent confidence interval 1.2 to 1.6). The outbreak was probably caused by a 27-28 nm small round structured virus found in the stool from one ill person. High levels of faecal coliforms in the reticulated river water and enterovirus in sediment samples suggest that the outbreak was caused by sewage contaminating the reticulated river water through a break in the pipe directly over the underground water tanks. To prevent such outbreaks, poor water and sewerage system layouts should be avoided and nonpotable water should be clearly labelled. Where feasible, all camping-ground water should stem from town supplies.

We conducted a randomized controlled trial to determine whether empirical treatment of severe acute community-acquired gastroenteritis (four fluid stools per day for > 3 days) with ciprofloxacin reduces the duration of diarrhea and other symptoms and to determine what effect ciprofloxacin has on the duration of long-term fecal carriage of gastrointestinal pathogens. A total of 173 patients were recruited for the study and received either ciprofloxacin (500 mg b.i.d.) or placebo for 5 days, during which time they recorded the duration of diarrhea and other symptoms (fever, abdominal pain, vomiting, and myalgia). Fecal samples were collected before treatment and regularly after treatment to determine the duration of carriage of gastrointestinal pathogens. Antibiotic susceptibility tests were performed, and the minimum inhibitory concentrations (MICs) of ciprofloxacin were determined. A significant reduction in the duration of diarrhea and other symptoms was observed after treatment, regardless of whether a pathogen was detected (P = .0001). Treatment failure occurred in 3 of 81 patients in the ciprofloxacin group and 17 of 81 patients in the placebo group. Significant pathogens were detected in 87% of patients, 85.5% of whom had cleared the pathogen at the end of treatment with ciprofloxacin, as compared with 34% who received placebo. Six weeks after treatment, there was no difference between the two groups in terms of the pathogen carriage rate (12%). Treatment with ciprofloxacin did not prolong carriage. High-level resistance to ciprofloxacin (MIC, > 32 mg/L) was detected in three strains (4%) of Campylobacter species.

The challenges of childhood abdominal pain are to treat the majority of children with self-limited conditions of obscure but benign causes and to identify the child with a rare, life-threatening cause of pain. The diagnostic algorithm of abdominal pain during childhood is best compartmentalized into three groups: infants, preschoolers, and school-age children. In infants, bilious vomiting heralds a life-threatening or surgically indicated disorder. Most nonsurgical conditions are related to gastroenteritis, constipation, and reflux. The majority of children with abdominal pain experience spontaneous resolution of their symptoms without specific management. For every 15 school-age children with abdominal pain, 1, at most, will have a serious condition such as appendicitis. Parents and children appreciate a careful appraisal of the symptoms, and the physician should listen to their concerns and perform a thorough examination. Laboratory or radiologic studies are rarely indicated.

A case of jejunojejunal intussusception in a 59 year old male secondary to a leiomyoma is reported. The patient presented with abdominal pain and vomiting. He was admitted with a diagnosis of gastroenteritis. Antegrade barium study showed a jejunojejunal intussusception with a soft tissue mass as the lead point. Computed tomography scan demonstrated the soft tissue mass to have properties suggestive of a leiomyoma. The diagnosis was confirmed on examination of the excised specimen.

We report a case of a 27-year-old pregnant patient who presented with severe colicky abdominal pain, diarrhoea and fever. She was initially treated for gastroenteritis. She later requested a termination of the pregnancy. Abdominal X-rays showed small bowel dilatation. A dynamic computed tomographic scan was performed and showed a splenic and superior mesenteric vein thrombosis. This was confirmed by colour duplex scanning and angiography. Anticoagulation with heparin was associated with dramatic relief of the symptoms and complete recanalisation of both veins. Surgical intervention was avoided.

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.

In November 1994 a major outbreak of acute gastroenteritis was experienced in the municipality of Klaebu (4,486 inhabitants). To investigate the course and extent of the epidemic, a questionnaire was mailed to all 1,573 households. The returned questionnaires covered 2,943 persons, of whom 1,640 (56%) were reported ill with the following most common symptoms: Nausea (83%), vomiting (78%), diarrhoea (72%) and abdominal pain (70%). The epidemic curve was typical of a common source epidemic. The incidence of vomiting turned out to have three distinct peaks with an interval of 26 hours, probably due to secondary infections. Two specimens that were examined by electron microscope showed typical Norwalk virus structures, and this virus was assumed to be the etiologic agent. The actual cause of this common-source epidemic was found to be inadequate chlorination. The onset of symptoms in different parts of the municipality showed that time taken for the infection to be transported from the reservoir to the consumers was longer than expected. Such delays allow for information on preventive measures to be communicated via the radio and other media.

Children and adolescents with inflammatory bowel disease (IBD) present unique challenges to physicians and all health-care providers. The most important aspect is that children are not small adults. They are characterized by a highly dynamic state of growth and physical change as well as a constant alteration in psychological status. It will not be difficult to recognize IBD, even in children, when it presents with classical symptoms such as bloody diarrhoea, abdominal pain and weight loss. However, some children will present with abdominal pain and depression. Not infrequently these children are diagnosed as being depressed and are seen and treated by psychologists and psychiatrists for different periods of time. In addition, several children will be initially diagnosed as having a bacterial gastroenteritis with a proven positive faecal culture. It seems to be the triggering event in these children, and if adequate therapy fails, colonoscopy is indicated. Recently, Beattie et al. showed that in children seen for chronic abdominal pain simple routine blood tests including full blood count and erythrocyte sedimentation rate are almost always abnormal in children with IBD. But most importantly, growth retardation is common in children with IBD and is more often found in Crohn's disease (CD) than in ulcerative colitis (UC). Faltering growth is a sign of a catabolic situation. Therefore, it is essential to follow the growth of children at the beginning and during treatment of IBD. Growth retardation can be the first symptom of IBD and is often already present before other symptoms of IBD become apparent. Rarely, extra-intestinal manifestations, particularly arthritis, can be the first and sometimes only initial symptom for months to years in children with IBD. About 2% of all patients with IBD present before the age of 10 years, but 30% present between the age of 10 and 19 years. A significant proportion of young patients with IBD will develop the disease just prior to or during puberty. Adolescent growth is characterized by rapid accumulation of lean body mass and any inflammatory disease occurring at this time is likely to have a major impact on nutritional status and growth. This rapid growth requires an appropriate increase in nutritional substrates and failure to achieve catch-up growth may ultimately lead to poor cumulative growth over time. Most of the growth retardation is seen in children with CD, approximately 30%. However, also in UC 15% will show a reduction in growth. The higher percentage in CD could be due to the disease itself or to the relative subtlety of the intestinal manifestations of CD, mainly abdominal pain and general malaise. Not only growth, but also delayed puberty, is a sign of an ongoing disease that most likely needs more intensive treatment. It has been shown that the severity of disease activity plays a more important role in the occurrence of growth retardation than steroid treatment. Therefore in paediatrics it is important to state that growth retardation during medical treatment equals undertreatment. In contrast to adults, the potential benefit of nutritional therapy should be seriously considered in addition to aggressive medical therapy including steroids and other immunosuppressive agents such as azathioprine. The most convincing evidence that malnutrition is primarily responsible for growth failure is based on depletion studies. The malnutrition itself is caused by ongoing inflammation and loss of appetite. Recommendations for nutritional therapy include an increase in energy and protein intake to 150% of recommended daily allowances for height and age. Some studies have shown the benefit of nocturnal nasogastric infusion as supplements of daily intake. Importantly, nutritional support has been shown to be as effective as steroids in achieving remission of disease in children. Furthermore, no significant differences have been shown in studies using elemental versus polymeric diets.

Coeliac disease is diagnosed by means of jejunal biopsy, an invasive procedure. Anti-gliadin antibodies (AGA) have therefore been used in the first screening of the disease. On the other hand, low titers of AGA are widely detected also in normal subjects. In order to investigate if low levels of AGA could be correlated with laboratory and clinical data, we performed a study on 167 subjects with various illnesses, such as recurrent abdominal pain, failure to thrive, short stature, diarrhoea or constipation, cow-milk protein intolerance and/or food allergy, recurrent vomiting or previous gastroenteritis, all non coeliac conditions which have been associated with AGA presence. Seventy coeliac children, all biopsied, were selected as a control group. Among the 167 cases we found 60 subjects positive for AGA (35.9%), a high proportion as compared with the general population. Only 33/167 patients, all IgG and IgA AGA positive, fulfil our laboratory and clinical criteria to perform a 'confirming' biopsy. For the 134 residual cases (14 IgA, 13 only IgG AGA positive, 107 AGA negative) a diagnosis of coeliac disease has been excluded by clinical criteria (scoring). As a whole, the patients with coeliac disease had significantly higher levels of AGA of both IgG and IgA classes (p < 0.01). On the other hand, no significant difference emerged for all the anamnestic and laboratory parameters considered between AGA+ and AGA- non-coeliac subjects. However, laboratory parameters of IgG-AGA and/or IgA-AGA positive patients were similar to those of coeliac children for ion, Xylose, total IgA count. As no biopsied case showed mucosal atrophy, it is suggested that the presence of even low AGA levels in non-coeliac children may represent a highly sensitive index of intestinal alteration causing an increased permeability to macromolecules, but it is very unlikely that one could detect coeliac children by means of Ig-AGA among such illnesses and normal subjects. Strong clinical diagnosis and laboratory parameters are required to justify intestinal biopsies. In fact, the production of AGA seems to be a merely immunological phenomenon linked to an increased and probably transient permeability to macromolecules of the intestinal mucosa.
