Our objective was to determine the ability of several clinical signs of dehydration to distinguish among degrees of dehydration in infants with acute diarrhea. The design was a prospective cohort study in a pediatric referral hospital in Cairo, Egypt. Infant boys, 3-18 months old, with a history of acute diarrhea (5 or more watery stools per day for no more than 7 days) were eligible, except those with frank protein-energy malnutrition, serious nongastrointestinal illness, or being exclusively breast-fed. Several clinical signs of dehydration were assessed upon study entry. Subjects were then rehydrated with an oral rehydration solution and fed a standardized diet until diarrhea ceased (no watery or loose stools for 16 h). The main outcome measure was percent body weight gain at rehydration and at resolution of illness. Data from 135 subjects were available for analysis. Average (SD) rehydration phase duration was 5.2 (2.1) h, and average (SD) duration of illness was 54.5 (38) h. Multiple regression analysis selected prolonged skinfold, altered neurologic status, sunken eyes, and dry oral mucosa as the clinical signs that correlated best with percent dehydration (R2 for model 0.244, p < 0.001). Mean weight gain for the two assessment systems was 3.6-3.9% for mild, 4.9-5.3% for moderate, and 9.5-9.8% for severe dehydration. The most valid clinical signs of dehydration include prolonged skinfold, altered neurologic status, sunken eyes, and dry oral mucosa. Children with clinical signs of mild or moderate dehydration have fluid deficits on the order of 3 or 5% body weight, respectively.

Fecal isolates of Clostridium difficile and its toxin B were followed prospectively in 50 preterm intensive care nursery (ICN) patients. The first stool specimen was obtained after 1 week of enteral feeding, at 15 ± 1 days of life, and 2 more specimens were collected at 2-week intervals, 24 ± 1 and 32 ± 2 days of life. The stools were cultured for C. difficile, and tested for C.difficile toxin B. In the first specimen 15% of stools grew C.difficile. In the second specimen C. difficile isolation rates increased to 33% and plateaued. Toxin B was detected in 71, 93 and 100% of culture-positive stools in the first, second, and third specimens, respectively. C.difficile colonization was not associated with a higher incidence of necrotizing enterocolitis or diarrhea, and using precollected, frozen human milk did not protect from C.difficile colonization.

ABSTRACT. The purpose of our study was to determine if the ethane content of expired air could be a useful index of vitamin E status in children. Eight children with vitamin E deficiency secondary to chronic severe liver disease were studied: six of these children were treated with parenteral vitamin E (2-5 mg/kg/dose every 4-7 d). Measures of vitamin E status pre-and posttherapy were: serum vitamin

This study was conducted to determine the prevalence of rheumatic heart disease (RHD) and congenital heart disease (CHD) in primary schoolchildren of Menoufia, Egypt and to study the relationship between these two problems and socioeconomic conditions. A total of 8000 children were screened for cardiac disease in their schools. Children with confirmed RHD and CHD in addition to 200 healthy children (controls) were visited at their homes to assess their social environment and other factors according to a designed questionnaire. We found prevalence rates of 3.4/1000 and 2.6/1000 for the RHD and CHD respectively. The most common cardiac defects were double mitral and pulmonary stenosis in the RHD and CHD groups respectively. Nineteen (39.6%) of the patients were diagnosed for the first time during the study. Penicillin prophylaxis was received by only four (14.8%) of the RHD children and none of the CHD children. The number of other affected siblings, increased multiparity, repeated abortion, and intake of contraceptives by mothers were significantly higher in families of the children with CHD. The proportion of illiterate, unskilled, and heavy smoking fathers was higher in the two patient groups. Family income was lowest in the RHD group, while increased crowding index and low whole social environment were significantly related to both RHD and CHD. Effective programs at the community and health service levels are needed in Menoufia to solve the problem of heart disease in schoolchildren in the immediate future.
