Acute gastroenteritis associated with seafood privately imported from the Pacific Islands.

AIMS: To investigate a potential link between consumption of food privately imported from the Pacific Islands and presentation with acute gastroenteritis to Middlemore Hospital Emergency Department. METHODS: This was a three month prospective observational case study that included patients aged greater than fifteen years presenting with acute gastroenteritis and a history of food privately imported from the Pacific Islands. Data included case demographics, symptoms, island of food origin and food type. Stool and blood samples were collected and analysed. RESULTS: Of 358 patients who presented to Middlemore Emergency Department during the study period with gastroenteritis, 34 (9.4%) had a history of consumption of food privately imported from the Pacific Islands. The seafood came from Tonga (23 cases), Samoa (10 cases) or Niue (1 case). The implicated seafood was shellfish (28 cases), jellyfish (2 cases), fish intestine (2 cases), seaweed or seaslug (1 case each). Fourteen patients (41%) provided stool samples; all were culture positive for Vibrio parahaemolyticus (VPH). CONCLUSIONS: This case series confirms a link between acute VPH gastroenteritis and consumption of seafood privately imported from the Pacific Islands. A number of public health initiatives to reduce the burden of VPH gastroenteritis among Auckland's Pacific Islanders have commenced. The Ministries of Health, Agriculture and Forestry are considering tighter controls or banning food privately imported from the Pacific Islands.

Factors influencing hospitalisation of infants for recurrent gastroenteritis in Western Australia.

OBJECTIVE: To determine factors affecting length of hospitalisation of infants for recurrent gastroenteritis using linked data records from the Western Australia heath information system. METHODS: A seven-year retrospective cohort study was undertaken on all infants born in Western Australia in 1995 who were admitted for gastroenteritis during their first year of life (n = 519). Linked hospitalisation records were retrieved to derive the outcome measure and other demographic variables for the cohort. Unlike previous studies that focused mainly on a single episode of gastroenteritis, the durations of successive hospitalisations were analysed using a proportional hazards model with correlated frailty to determine the prognostic factors influencing recurrent gastroenteritis. RESULTS: Older children experienced a shorter stay with an increased discharge rate of 1.9% for each month increase in admission age. An additional co-morbidity recorded in the hospital discharge summary slowed the adjusted discharge rate by 46.5%. Aboriginal infants were readmitted to hospital more frequently, and had an adjusted hazard ratio of 0.253, implying a much higher risk of prolonged hospitalisation compared to non-Aborigines. CONCLUSIONS: The use of linked hospitalisation records has the advantage of providing access to hospital-based population information in the context of medical informatics. The analysis of linked data has enabled the assessment of prognostic factors influencing length of hospitalisations for recurrent gastroenteritis with high statistical power.

[Gastroenteritis of a nonbacterial nature in Sverdlovsk children].

The analysis of the results of the clinico-epidemiological and laboratory examination of children with clinical manifestations of acute gastroenteritis, admitted to specialized hospitals in Sverdlovsk during 1982-1983, showed that morbidity rate in Sverdlovsk was determined mainly by cases registered among children during the first 2 years of their life. Morbidity rate among children aged up to 1 year was 3-6 times higher than that among children of other age groups. Cases of gastroenteritis among children not belonging to organized groups were observed 3.9 times more frequently than in organized groups of children. Gastroenteritis of viral etiology constituted 50% of all nonbacterial enteric infections in young children, the course of gastroenteritis being more favorable in children aged up to 3 months than in older children. 54% of gastroenteritis cases in children aged up to 1 year and 71% of such cases in children aged 1-2 years proved to be of rotavirus etiology.

Gastroenteritis in children: principles of diagnosis and treatment.

Gastroenteritis in children is a common reason for visits to family physicians. Most cases of gastroenteritis have a viral etiology and are self-limited. However, more severe or prolonged cases of gastroenteritis can result in dehydration with significant morbidity and mortality. This is often the scenario in third-world countries, where gastroenteritis results in 3 million deaths annually. A proper clinical evaluation will allow the physician to estimate the percentage of dehydration and determine appropriate therapy. In some situations, laboratory studies such as determination of blood urea nitrogen and serum electrolytes may be helpful. Stool studies are indicated if a child is having bloody diarrhea or if an unusual etiology is suspected, such as Escherichia coli O157:H7 or Cryptosporidium. Most children with gastroenteritis can be treated with physiologically balanced oral rehydration solutions. In children who are hypovolemic, lethargic and estimated to be more than 5 percent dehydrated, initial treatment with intravenous boluses of isotonic saline or Ringer's lactate may be required. Children with severe diarrhea need nutrition to restore digestive function and, generally, food should not be withheld.

Gastroenteric fistula complicating percutaneous endoscopic gastrostomy.

BACKGROUND: Gastroenteric fistula occurs in 2% to 3% of patients undergoing percutaneous endoscopic gastrostomy (PEG). The authors identified 12 children with this major complication. METHODS: A retrospective case note review was performed. RESULTS: Over a 5-year period, the complication rate for gastroenteric fistula was 3.5% (12 of 343 procedures). Presentation ranged from 1 day to 25 months post-PEG insertion. Eight patients presented with acute intestinal obstruction. The gastroenteric fistulous tract involved the posterior wall of the stomach in all cases. The plain abdominal x-ray was useful in establishing the diagnosis of the gastroenteric fistula. CONCLUSIONS: Patients with gastroenteric fistula as a complication of PEG insertion can remain asymptomatic for prolonged periods. It often is difficult to make the diagnosis. A plain abdominal x-ray is a useful diagnostic modality.

Evaluation of gastroenteric bypass for unresectable pancreatic cancer.

BACKGROUND/AIMS: It is controversial as to whether gastroenteric bypass is helpful for patients with unresectable pancreatic cancer. This study was designed to evaluate the effects of gastroenteric bypass on dietary intake and the symptoms of gastric outlet obstruction in these patients. METHODOLOGY: We reviewed the cases of 101 patients with unresectable pancreatic cancer surgically treated at the Kobe University Hospital. The effects of gastroenteric bypass were examined by comparing the dietary intake and the symptoms of gastric outlet obstruction on admission, 1 month and 3 months after the operation. RESULTS: The analyses of dietary intake and the symptoms indicated that the gastroenteric bypass operation was not helpful for most of the patients with unresectable pancreatic cancer. Multivariate logistic regression model revealed that dietary intake on admission was the strongest parameter for dietary intake at one month after operation. The patients with a low dietary intake on admission often required a nasogastric tube after the bypass operation, reflecting progression of the disease. CONCLUSIONS: Gastroenteric bypass had no advantage to improve dietary intake and symptoms for almost all the patients with unresectable pancreatic cancer. It was effective only for patients with a high dietary intake without symptoms of gastric outlet obstruction on admission.

Clinical Impact and Genetic Analysis of Enteric Viruses Associated With Acute Gastroenteritis in Greater Accra, Ghana: A Comprehensive Study of Five Viruses.

Enteric viruses are significantly associated with acute gastroenteritis globally. Despite a decrease in severe rotavirus associated diarrhoea, Ghana still records high diarrhoea burden. Meanwhile aetiological investigations in hospital settings do not routinely include viral testing. Rotavirus vaccination is thought to alter enteric viral populations and impact evolution. To better understand virus-specific effects in acute gastroenteritis in both children and adults, we tested fecal samples from 228 patients at two hospitals in Accra from January to December 2019, using multiplex and singleplex PCR assays. The clinical impact of detected viruses was assessed using a modified Vesikari score system. Partial viral genome sequences were obtained by Sanger Sequencing and their genetic diversity and evolutionary history, traced by phylogenetic analyses. At least one enteric virus was found in 86 (37.7%) patient samples, with 36.9% of the population under five infected. Single infections of rotavirus, norovirus, adenovirus, sapovirus and astrovirus were 33, 14, 8, 6, and 1, respectively, while coinfections were 24. Rotavirus accounted for 33.3% of 24 clinically severe cases (modified Vesikari score > 7). Three out of 10 rotavirus cases with evidence of vaccination experienced severe gastroenteritis. Diverse genotypes, including RVA G2P[4], G1P[8], G12P[8] and G12P[6]; AdV F40 and F41; NoV GII.4 Sydney 2012, GII.6 and GI.3, several of which clustered with contemporary strains from the Americas, Europe and Asia, were detected. This study also provides the first report of SaV GI.1, GI.7 and GII.8 detection in humans in Ghana. RVA G2P[4] and AdV F were associated with higher proportions of hospitalizations. While RVA continues to have a profound clinical impact on gastroenteritis, AdV and SaV produce an equally severe disease. In contrast, NoV and AstV showed a generally mild to moderate impact on clinical disease severity.

Oral transmission of transmissible gastroenteritis virus by muscle and lymph node from slaughtered pigs.

A study was conducted in the USA to determine whether transmissible gastroenteritis (TGE) virus could be transmitted from carcases of slaughtered pigs. Transmissible gastroenteritis virus was transmitted to 6-day-old piglets by dosing with homogenates of muscle and lymph node collected from 500 clinically normal pigs at the time of slaughter. All piglets in 2 separately housed litters showed clinical signs of TGE with 5 piglets dying within 10 d of oral dosing with homogenates. Transmissible gastroenteritis virus was isolated from 2 of these piglets and all piglets developed TGE antibody. Transmissible gastroenteritis virus was not isolated in tissue culture from muscle and lymph node homogenates, but was isolated from 4 (0.8%) of 500 tonsil samples collected from the same pigs. A survey of 250 serum samples provided an estimate of the prevalence of slaughtered pigs with TGE antibody of 34.8% in the sample population. The results indicate that carcases of some pigs from TGE endemic areas contain viable TGE virus, and that there would be a substantial risk of introducing TGE virus into Australia by the importation of uncooked pig meat from these areas.

The use of immunofluorescence techniques for the laboratory diagnosis of transmissible gastroenteritis of swine.

Over a four year period, 74 of 250 field outbreaks of enteric disease (30%) and 110 of 440 swine (25%) were positive for transmissible gastroenteritis by immunofluorescence procedures. Of 141 swine from herds positive for transmissible gastroenteritis 110 (78%) were positive by fluorescent antibody techniques. The fastest, easiest to perform and most effective procedure was the examination of frozen sections of the jejunum from acutely ill animals by the fluorescent antibody tissue section technique. Only two herds were found to be positive by the fluorescent antibody tissue culture technique which were negative by fluorescent antibody tissue section technique. A considerable number of outbreaks, 21 of 74 (28%), of transmissible gastroenteritis were detected by immunofluorescence in swine over two weeks of age. The majority of outbreaks of transmissible gastroenteritis, 50 of 74 (68%), occurred in Missouri during the months of January through April and 63 of 74 (85%) during the months of December through May. The recurrence of the disease in a number of counties over a four-year period suggest the possibility of endemic foci.

A large nontypical outbreak of Norwalk virus. Gastroenteritis associated with exposing celery to nonpotable water and with Citrobacter freundii.

The US Air Force Academy experienced a point-source outbreak of gastroenteritis originally believed to be caused by Salmonella. The overall attack rate was 48% among approximately 3000 cadets and staff. Food-specific attack rates implicated chicken salad. The odds ratio for chicken salad consumption in ill cadets was 10.7 (95% confidence interval: 8.2; 13.8). The celery component had been exposed to nonpotable water. Citrobacter freundii were statistically associated with consumption of the suspected vehicle and subsequent illness. Most aspects were consistent with the epidemiology of Norwalk gastroenteritis. However, the clinical presentation was not typical of reported outbreaks. One hundred five cadets required intravenous rehydration. Serum samples implicated Norwalk virus as the most probable cause of this outbreak. The Centers for Disease Control (Atlanta, Ga) recently began national surveillance for viral gastroenteritis. All outbreaks of gastroenteritis associated with nonpotable water should be investigated for evidence of viral cause.

Laryngeal cleft and eosinophilic gastroenteritis: report of 2 cases.

Although laryngotracheoesophageal clefts are often found in association with other well-described anomalies, we know of no previous reported association with eosinophilic gastroenteritis, a disorder of unknown etiology characterized by eosinophilic infiltration of the gastrointestinal tract. We treated 2 children who had laryngeal clefts and eosinophilic gastroenteritis. Since the esophageal inflammatory changes found in eosinophilic gastroenteritis may persist despite aggressive therapy, management of the laryngotracheoesophageal clefts is more complicated. The diagnosis of eosinophilic gastroenteritis should not be overlooked in patients with laryngotracheoesophageal clefts and warrants prompt referral to a pediatric gastroenterologist.

Rotavirus gastroenteritis in the Washington, DC, area: incidence of cases resulting in admission to the hospital.

The incidence of rotavirus gastroenteritis in infants and children that required admission to the hospital was estimated for a defined population of approximately 105,000 individuals, including 29,000 children aged 15 years or younger whose primary health care was provided by Group Health Association, Inc, a health maintenance organization in the Washington, DC, area. From January 1977 through March 1979, almost all infants and children in this age group who required hospitalization for gastroenteritis were studied for evidence of infection with human rotavirus (HRV) and other agents. On the average, one in 272 (3.7/1,000) infants less than 12 months old and one in 451 (2.2/1,000) children aged 13 through 24 months were hospitalized for HRV disease each winter. The incidence of rotavirus gastroenteritis requiring hospitalization declined precipitously in children after the second birthday and such illness was not detected in children aged 5 years or older. The role of other agents in acute gastroenteritis requring hospitalization was minimal, compared with that of rotavirus.

Campylobacter infection associated with raw milk. An outbreak of gastroenteritis due to Campylobacter jejuni and thermotolerant Campylobacter fetus subsp fetus.

Raw milk is identified with increasing numbers of outbreaks of gastroenteritis and is an important vehicle for transmission of Campylobacter infection. Unlike Campylobacter jejuni, Campylobacter fetus subsp fetus has not been associated with common-source outbreaks of gastroenteritis. This report describes an outbreak of gastroenteritis involving C jejuni and a thermotolerant strain of C fetus subsp fetus associated with raw milk. Fifteen (39%) of 38 persons who attended a banquet in Wisconsin in June 1982 developed acute gastroenteritis. Stool specimens were obtained from nine ill guests; four yielded C jejuni and three yielded C fetus subsp fetus. The C fetus subsp fetus isolates were identified fortuitously, in part because of unusual thermotolerance (growth at 42 degrees C), permitting isolation at temperature appropriate for C jejuni. Survey results implicated raw milk as the source of the outbreak. Findings provide evidence of a potentially emergent milkborne pathogen contributing to the risk of raw milk consumption and suggest that current diagnostic laboratory techniques may fail to identify significant foodborne agents.

Antiemetics for reducing vomiting related to acute gastroenteritis in children and adolescents.

BACKGROUND: Vomiting caused by acute gastroenteritis is very common in children and adolescents. Treatment of vomiting in children can be problematic and the use of antiemetics remains a controversial issue. There have been concerns expressed about apparently unacceptable levels of side effects such as sedation and extrapyramidal reactions, which are associated with some of the earlier generation of antiemetics. OBJECTIVES: To assess the effectiveness of antiemetics on gastroenteritis induced vomiting in children and adolescents. SEARCH STRATEGY: We searched the Cochrane Central register of Controlled Trials (CENTRAL), which includes the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group Trials Register (searched 28 July 2005), MEDLINE (1966 to July 2005) and EMBASE (1980 to July 2005). Published abstracts from conference proceedings from the United European Gastroenterology Week and Digestive Disease Week were handsearched. Members of the Cochrane UGPD Group were contacted for details of any ongoing or relevant unpublished clinical trials. SELECTION CRITERIA: Randomised controlled trials comparing antiemetics and/or placebo in children and adolescents, under the age of 18, with vomiting due to gastroenteritis. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects data was collected from the studies. MAIN RESULTS: Two trials involving 181 participants were included. Although no data were available for the precise time to cessation of vomiting (the primary outcome specified in the protocol for this review), one trial reported that the proportion of patients without vomiting over a 24 hour period was higher in the ondansetron and metoclopramide groups than placebo. In the second trial, ondansetron ensured complete anti-emesis for 8/12 (67%) patients within the first 4 hours and in 7/12 (58%) patients in the first 24 hr period. A few secondary outcomes were reported in the included trials. AUTHORS' CONCLUSIONS: The small number of included trials provided some, albeit weak and unreliable, evidence which appeared to favor the use of ondansetron and metoclopramide over placebo to reduce the number of episodes of vomiting due to gastroenteritis in children. The increased incidence of diarrhea noted with both ondansetron and metoclopramide was considered to be as a result of retention of fluids and toxins that would otherwise have been eliminated through the process of vomiting.

A study of the prevalence of rotavirus infection in children with gastroenteritis admitted to an infectious diseases hospital.

In a 12 month survey of infants and children with gastroenteritis admitted to Fairfield Hospital, Melbourne, rotavirus was found in approximately 42% of patients. This virus was detected more often during the winter months, particularly in children aged between 12 months and 3 years. Detection of rotavirus by electron microscopy was found to be more sensitive than by counterimmunoelectrophoresis. Routine bacterial and viral studies revealed that bacterial pathogens and common enteric viruses were associated with relatively few cases of gastroenteritis. There is little doubt that rotavirus is the most important aetiological agent of acute gastroenteritis in yvirus is the most important aetiological agent of acute gastroenteritis in young children in Melbourne.

The 33- to 39-nm virus-like particles, tentatively designed as Sapporo agent, associated with an outbreak of acute gastroenteritis.

An outbreak of nonbacterial gastroenteritis occurred in an orphanage in December 1979. Of 54 residents, 43 were affected with acute gastroenteritis. Diarrhea was the commonest symptom. The 33- to 39-nm virus-like particles, tentatively designated as Sapporo agent, were detected in 17 (48.6%) of the patients' 35 fecal specimens. Morphologically, it was difficult to distinguish the Sapporo agent from other agents without geometrical pattern of the surface. Antigenically, the Sapporo agent related to the Otofuke agent detected in an outbreak of the institution for mentally retarded adults and also to the SRV ;76 detected in familial cases of infectious gastroenteritis. The Sapporo agent might belong to a new group of those gastroenteritis viruses which were larger in size than the Norwalk virus group.

High rate and changing molecular epidemiology pattern of norovirus infections in sporadic cases and outbreaks of gastroenteritis in Hong Kong.

Noroviruses (Norwalk-like viruses (NLV)) are recognised as major causes of acute gastroenteritis worldwide. Numerous studies had been carried out on the molecular epidemiology of norovirus in outbreaks but relatively few on sporadic cases. In this study, the molecular epidemiology of noroviruses in sporadic and outbreak cases of acute gastroenteritis in Hong Kong was examined over a 12-month period from July 2001 to June 2002. Specimens from three groups of patients were used in this study. Nine hundred ninety-five specimens from patients enrolled in the Acute Diarrhoeal Diseases Surveillance Programme of the Department of Health, Hong Kong Government; 735 clinical specimens from hospital patients with acute gastroenteritis, and 122 specimens from 44 norovirus outbreaks. Ninety-two (9.2%) surveillance specimens were positive for norovirus RNA by reverse transcription-polymerase chain reaction (RT-PCR), compared to 123 (16.7%) clinical and 101 (82.8%) outbreak specimens. For the first 6 months of the study period, the predominant strain was the Bristol strain that belongs to genogroup II (GII). In the latter 6 months of the study, genogroup I (GI) and strains belonging to other clusters of GII were seen more commonly. The vast majority of strains belonging to the Bristol virus cluster were closely related to the 95/96-US subset that was associated with pandemic infection from 1995 onwards. This study clearly establishes the importance of norovirus as a cause of sporadic cases of acute gastroenteritis in all age groups in Hong Kong.
