A 16-year-old adolescent presented with fever, lethargy and vomiting associated with mild dehydration. This was followed less than 24-hours later by loss of consciousness, seizures and clinical brain death. She had no prior medical illness, no hospital or frequent antibiotic exposure. There was no evidence of soft tissue or skin infection. Management included intravenous fluids, ampicillin and cefotaxime parenterally, dexamethasone, endotracheal intubation and mechanical ventilation. Her neurologic examination remained unchanged with areflexia, flaccid paralysis and fixed pupils. Post-mortem examination revealed an eight-centimetre right fronto-parietal lobe brain abscess. Cultures were positive for methicillin resistant Staphylococcus aureus. Although formerly a nosocomial pathogen affecting debilitated patients in the hospital setting, S aureus that is methicillin resistant is emerging as a community acquired pathogen affecting previously well patients.

Gayet-Wernicke syndrome is a rare neurological pathology due to a deficit in vitamin B1. It occurs in alcoholics but several reports have been published of cases in a context of intractable vomiting. The frequency is probably under-estimated because there have been many cases described at autopsy. The diagnosis is clinical with the triad (found in 60% of cases) of mental confusion, oculomotor disorders and ataxia. MRI can confirm the diagnosis by hyper signal images most frequently in a peri-acqueductal location, the thalamus and mamillary bodies. We report 3 observations of Gayet-Wernicke encephalopathy discovered in a context of hyperemesis gravidarum. These 3 cases, which occurred within the past two years in the West of France, give us the opportunity to assess 3 different outcomes for this pathology. In a second section we review the main publications in the literature. Hyperemesis gravidarum is a frequent pathology and can be the cause of serious neurological complications. Early vitamin supplementation should be instituted in case of severe vomiting in order to ensure the pregnancy can continue together with the mother's well-being.

West Nile virus (WNV) is a RNA virus of the Flaviridae, genus flavivirus family. It is a neuropathogenic virus causing disease in birds, horses and humans. WNVis transmitted by the vector mosquito Culex sp. The virus life 's cycle includes mosquitoes as vectors and birds as natural hosts. Humans are accidental hosts. Since the introduction of the Epidemiological Surveillance Program at the Ministry ofHealth. we have documented 90 positive test results among birds out of 1,223 cases studied in Mexico as of September IS. 2005. The incubation period in humans after a mosquito bite ranges from 3 to 14 days. Disease is characterized by early onset fever, general malaise, decreased appetite, nausea, vomiting, headaches, myalgias, enlarged lymph nodes andrash. Neurological manifestations include encephalitis andflaccid paralysis, which are present in less than 1% of subjects infected with WNV. Older patients display more adverse outcomes including death. The diagnosis is made by the determination of specific IgM and JgG antibodies in serum and/or cerebrospinal fluid. There is no antiviral treatment to date against WNV but interferon ?2b, and WNVspec4ic-immunoglobulin have been used Prevention is therefore the key to control the infection.

Lassa fever is an acute viral zoonotic illness caused by Lassa virus, an arenavirus known to be responsible for a severe haemorrhagic fever characterised by fever, muscle aches, sore throat, nausea, vomiting and, chest and abdominal pain. The virus exhibits persistent, asymptomatic infection with profuse urinary virus excretion in the ubiquitous rodent vector, Mastomys natalensis. Lassa fever is endemic in West Africa and has been reported from Sierra Leone, Guinea, Liberia, and Nigeria. Some studies indicate that 300,000 to 500,000 cases of Lassa fever and 5000 deaths occur yearly across West Africa. Studies reported in English, that investigated Lassa fever with reference to West Africa were identified using the Medline Entrez-PubMed search and were used for this review. The scarcity of resources available for health care delivery system and the political instability that characterise the West African countries would continue to impede efforts for the control of Lassa fever in the sub-region. There is need for adequate training of health care workers regarding diagnostics, intensive care of patients under isolation, contact tracing, adequate precautionary measures in handling infectious laboratory specimens, control of the vector as well as care and disposal of infectious waste.

On October 17, 2006, the West Virginia Department of Health and Human Resources (WVDHHR) was notified of an outbreak of acute gastroenteritis, characterized by vomiting and diarrhea, among attendees at a family reunion. The outbreak initially was reported by a group of attendees to their local health department in Garrett County, Maryland. The same day, the information was relayed to the Grant County Health Department in West Virginia and subsequently to WVDHHR. The reunion was held on October 14 at a private residence in Grant County, West Virginia, and the 53 identified attendees included residents from Florida, Maryland, New York, Pennsylvania, Virginia, and West Virginia. This report describes a collaborative, multijurisdictional epidemiologic investigation using a cohort study and laboratory analyses to determine the source of infection and appropriate control measures. The results indicated that a combination of person-to-person and foodborne transmission of two strains of norovirus, likely introduced by persons from two different states and subsequently at least two food items, was the probable cause of these illnesses, highlighting the challenge of investigating and controlling norovirus outbreaks. During periods of peak norovirus activity, public health officials should emphasize the importance of appropriate handwashing and the exclusion of ill persons from social gatherings.

The aim of the study was to evaluate and document the efficacy and tolerability of rabeto plus (FDC of rabeprazole and itopride) in management of functional dyspepsia. It was an open, prospective, non-comparative, multidose study. The patients with functional dyspepsia (NERD or non-erosive reflux disease) attending OPD of a leading, tertiary care, teaching hospital in West Bengal (BS Medical College, Bankura) were inducted in the study. A total of 46 adult patients of either sex with functional dyspepsia and a clinical diagnosis of NERD were given 1 capsule of rabeto plus before breakfast, for up to 4 weeks. Primary efficacy variables were relief from symptoms of heartburn, nausea, vomiting, waterbrash and fullness. Secondary efficacy variables were global assessment of efficacy and toleration by patients and treating physicians. The tolerability was assessed on the basis of record of spontaneously reported adverse events with their nature, intensity and outcome. Out of 55 patients enrolled in the study, 46 completed the study as planned, while 9 patients were lost to follow-up (dropped). Most patients reported near total symptom relief by the end of study. Total symptom score showed remarkable and significant improvement from baseline to end of the study. Importantly, none of the patients reported any side-effect. All participants tolerated the drug well. Moreover, response to study drug was rated as excellent or good by over 93% patients and their treating physicians. This means that 9 out 10 patients receiving rabeto plus reported desired symptom relief from dyspepsia. Thus it was concluded that rabeto plus is a valuable drug for treatment of functional dyspepsia or NERD.

Autosomal dominant polycystic kidney disease may present to the emergency department (ED) with vomiting, abdominal pain or hernias, renal insufficiency or failure, or bleeding from cerebral aneurysms. A 37-year-old man presented to the ED with signs and symptoms of incarcerated inguinal hernia. Laboratory studies showed renal failure with anion gap acidosis, and bedside ultrasound showed multicystic kidneys. Computed tomography confirmed the diagnosis. Emergency physicians should be aware of this common connective tissue defect and its serious associated conditions.

In the past two decades, peanut allergy prevalence has increased in the West but has been perceived as having remained low in Asia. To review the clinical presentation of Asian children with peanut hypersensitivity and measure their IgE responses to major peanut allergens. We enrolled 31 children presenting with various allergies and a positive skin prick test to peanut from the Children's hospital outpatient allergy clinic in Singapore. A detailed questionnaire was completed by parents. The children's serum IgE specific to native Ara h 1, native Ara h 2, and recombinant Ara h 3 were detected using ELISA. Of the 31 patients, 19 had previously documented reactions to peanuts, while 12 had no previous clinical reaction. Most, 89.5% (17/19) of first reactions featured skin changes (urticaria, erythema, angioedema), but only 36.8% (7/19) involved skin symptoms alone. Respiratory symptoms and GI symptoms occurred in 42.1% and 26.3% of patients respectively and did not occur as the sole manifestation of reaction. The most common GI manifestation was emesis, present in 26.3% (5/19) of subjects. Two children experienced impaired consciousness with systemic, anaphylactic events. Although most sought treatment for their first peanut reaction only one patient received epinephrine. Half of our patients reported a subsequent accidental ingestion after the diagnosis of peanut allergy, with a median time from diagnosis to first accidental ingestion of 4 months and a reported increased severity of reaction in approximately half of the repeat exposures. Eighty-seven percent of children had specific IgE directed against at least one of the major peanut allergens. Among all patients, 87.1% had IgE specific to both Ara h 1 and Ara h 2 and 54.8% to rAra h 3. Asian children with peanut sensitization have clinically similar presentations and respond to the same major allergenic proteins as their Western counterparts. The perceived differences between the populations in this context do not stem from divergent clinical or immunological responses.

A population-based telephone survey of acute gastroenteritis (AG) was conducted in Hong Kong from August 2006 to July 2007. Study subjects were recruited through random digit-dialing with recruitments evenly distributed weekly over the 1-year period. In total, 3743 completed questionnaires were obtained. An AG episode is defined as diarrhoea >or=3 times or any vomiting in a 24-h period during the 4 weeks prior to interview, in the absence of known non-infectious causes. The prevalence of AG reporting was 7%. An overall rate of 0.91 (95% CI 0.81-1.01) episodes per person-year was observed with women having a slightly higher rate (0.94, 95% CI 0.79-1.08) than men (0.88, 95% CI 0.73-1.04). The mean duration of illness was 3.6 days (S.D.=5.52). Thirty-nine percent consulted a physician, 1.9% submitted a stool sample for testing, and 2.6% were admitted to hospital. Of the subjects aged >or=15 years, significantly more of those with AG reported eating raw oysters (OR 2.4, 95% CI 1.3-4.4), buffet meals (OR 1.8, 95% CI 1.3-2.5), and partially cooked beef (OR 1.8, 95% CI 1.2-2.7) in the previous 4 weeks compared to the subjects who did not report AG. AG subjects were also more likely to have had hot pot, salad, partially cooked or raw egg or fish, sushi, sashimi, and 'snacks bought at roadside' in the previous 4 weeks. This first population-based study on the disease burden of AG in Asia showed that the prevalence of AG in Hong Kong is comparable to that experienced in the West. The study also revealed some 'risky' eating practices that are more prevalent in those affected with AG.
