From Aug 2001 to July 2002 at St Paul Hospital in Hanoi, 300 fecal samples collected from 300 diarrhoea children aged from 3 months to 5 years old were studied. Results showed that in 51,9% of cases, rotavirus was the leading cause, Escherichia coli was the second, among which addhesive strains and invasive strains of coli were the most common. In first time, toxic gene was detected in the group of intestinal hemorrhagic Escherichia coli. Shigella and Campillobacter were still the common pathologic causes of pediatric diarrhoae

Natural disasters may lead to the outbreaks of infectious diseases because they increase the risk factors for infectious diseases. This paper reviews the risk factors for infectious diseases after natural disasters, especially earthquake, and the infectious diseases following disasters reported in recent years. The infectious diseases after earthquake include diarrhea, cholera, viral hepatitis, upper respiratory tract infection, tuberculosis, measles, leptospirosis, dengue fever, tetanus, and gas gangrene, as well as some rare infections. Children are vulnerable to infectious diseases, so pediatricians should pay more attention to the research on relationship between infectious diseases and natural disasters.

This paper describes the first case of common variable immunodeficiency (CVID) and AA amyloidosis. A recently treated tuberculosis, and chronic inflammation induced by frequent respiratory tract infections, were thought to be responsible for the amyloidosis. No other reason for this condition could be detected. Although T cell dysfunction in some CVID patients has been reported, pulmonary tuberculosis is quite rare with this condition. Bacterial or viral agents or evidence in favour of intestinal tuberculosis, which would explain this patient's recurrent diarrhea, were not found. In this case, the response of the attacks of diarrhea to metranidazole and the histologic observation of extensive intestinal amyloid deposition, which is known to decrease intestinal motility, made us conclude that the diarrhea was associated with bacterial overgrowth. In this report, we discuss the association of CVID and tuberculosis to secondary amyloidosis and recurrent diarrhea.

Antibiotics-associated diarrhea (AAD) is defined as unexplained diarrhea that occurs with the administration of antibiotics. Approximately 20% AAD cases are due to Clostridium difficile. Over the last decade, the incidence of Clostridium difficile-associated disease (CDAD) has progressively increased, and now a significant clinical problem. Recent change in the epidemiology of CDAD and the emergence of an epidemic hypervilruent strain suggest the need for greater attention for infection control, early diagnosis, and more effective treatment modality. However, since most cases of CDAD are both iatrogenic and nosocomial, careful selection of antibiotics, combined with proper hand hygiene and precaution by medical staffs are required.

OBJECTIVETo explore digestive system manifestations in patients with severe acute respiratory syndrome (SARS).

METHODThe clinical data of 96 cases with SARS admitted into our hospital from February 6, 2003 to March 28, 2003 were retrospectively analyzed.

RESULTSAmong the 96 cases, 26 cases (27%) had diarrhea, 17 (18%) had nausea, 6 (6%) had vomiting, 16 (17%) had bellyache, and 8 (8%) had ALT elevation.

CONCLUSIONSPatients with SARS may have digestive system manifestations; diarrhea is the most common symptom.

OBJECTIVETo investigate the development of lactose intolerance in neonates with non-infectious diarrhea and its association with diarrhea, and to evaluate the diagnostic values of fecal pH value and urine galactose determination for neonatal lactase deficiency.

METHODSSeventy hospitalized neonates who developed non-infectious diarrhea between October 2012 and June 2015 were enrolled as the diarrhea group, and 162 hospitalized neonates without non-infectious diarrhea were enrolled as the non-diarrhea group. Test paper was used to determine fecal pH value. The galactose oxidase method was used to detect urine galactose. The neonates with positive galactose oxidase were diagnosed with lactase deficiency, and those with lactase deficiency and diarrhea were diagnosed with lactose intolerance. According to the results of urine galactose detection, 69 neonates in the diarrhea group who underwent urine galactose detection were classified into lactose intolerance group (45 neonates) and lactose tolerance group (24 neonates), and their conditions after treatment were compared between the two groups. The follow-up visits were performed for neonates with diarrhea at 3 months after discharge.

RESULTSFecal pH value and positive rate of urine galactose (65% vs 54%) showed no significant differences between the diarrhea and non-diarrhea groups (P>0.05). Fecal pH value showed no significant difference between the lactose intolerance and lactose tolerance groups (P>0.05), while the neonates in the lactose intolerance group had a significantly longer time to recovery of defecation than those in the lactose tolerance group (P<0.05).

CONCLUSIONSThe incidence of lactase deficiency is high in neonates, and diarrhea due to lactose intolerance tends to occur. Determination of fecal pH value has no significance in the diagnosis of lactose intolerance in neonates with diarrhea.
