Effect of four plant phenols, beta-carotene and alpha-tocopherol on 3(H)benzopyrene-DNA interaction in vitro in the presence of rat and mouse liver postmitochondrial fraction.

The modulatory effect of beta-carotene, alpha-tocopherol and the four plant phenols eugenol, hydroxychavicol, curcumin and catechin on mouse and rat liver postmitochondrial fraction (S9 mix)-mediated 3(H)benzopyrene (B(a)P)-DNA interaction in vitro was studied. All the plant phenolics significantly inhibited 3(H)B(a)P-DNA interaction in the presence of both mouse and rat liver S9 fractions. In contrast, alpha-tocopherol proved to be ineffective in the presence of both types of S9 mix, whereas beta-carotene inhibited only mouse S9 mix-mediated 3(H)B(a)P-DNA interaction.

Ciprofloxacin for treatment of severe typhoid fever in children.

Eighteen children with bacteriologically confirmed severe typhoid fever were initially treated intravenously with ciprofloxacin (10 mg/kg of body weight per day). Clinical cure with eradication of multiresistant Salmonella typhi infection was observed in 17 patients (94.4%; 95% confidence interval [CI], 84 to 100%). Children regained normal consciousness within an average of 2 days (95% CI, 1.8 to 2.2 days). The temperatures of the children returned to normal within 3.3 days (95% CI, 3.1 to 3.5 days). Complications were not observed during the hospital stay or a 3-month follow-up period. Relapse and carrier state were also not encountered during the follow-up period.

Influence of admission weight on neonatal mortality amongst hospitalised neonates in Calcutta.

The study was conducted on 785 neonates aged up to 28 days to evaluate the influence of admission weight on mortality. It was observed that there were 200 (25.5%) cases of septicaemia, 134(17.1%) of diarrhoea, 120(15.3%) each of prematurity related conditions and neonatal jaundice, 117(14.9%) of respiratory diseases and 94 (11.9%) cases of convulsion. There were total 182(23.18%) deaths comprising 70(38.5%) from prematurity related conditions, 40(22%) from diarrhoea, 35(19.2%) from respiratory diseases, 26(14.3%) from septicaemia, 8(4.4%) from neonatal jaundice and 3(1.6%) deaths from convulsion. The incidence of deaths among neonates weighing less than 2500 g on admission was 59.2% in diarrhoeal diseases, 53.4% in respiratory diseases and 44.6% in other conditions compared to those of 10%, 8.2% and 7.1% respectively in neonates having admission weight more than 2500 g. The findings are statistically significant. The results of the study indicate that low admission weight should be considered as a predictor of mortality among neonates.

Prospective hospital based study on persistent diarrhoea.

A total of 383 children aged less than 5 years suffering from acute watery diarrhoea or dysentery were studied in hospital to determine the rate of persistent diarrhoea. Altogether 335 (87.5%) recovered within 13 days. Only in 48 (12.5%) did the diarrhoea continue for 14 days or more, and they were considered as having persistent diarrhoea. Children aged between 7 and 18 months had a significantly increased incidence of persistent diarrhoea. Children suffering from grade II-IV malnutrition constituted the majority (70.8%) of those with persistent diarrhoea. Higher rates of isolation of Shigella flexneri, Shigella dysenteriae 1, and Salmonella typhimurium were observed among patients with persistent diarrhoea than in those with diarrhoea of shorter duration. No positive correlations were observed between the clinical severity of disease at hospital admission and measles. Breast fed babies were not prone to persistent diarrhoea.

Clinical & bacteriological profiles of shigellosis in Calcutta before & after an epidemic (1984-87).

Patients below 5 yr of age, hospitalised for shigellosis over a period of four years (1984-87), were studied. During the epidemic of bacillary dysentery (1984) isolation of different Shigella spp. as well as Shigella dysenteriae type 1 was high. Decreased isolation of Sh. dysenteriae type 1 and increased isolation of Sh. flexneri was observed during post-epidemic years (1985-87). Isolation of different Shigella spp. was always above 25 per cent from patients with dysentery and greater than 7 per cent from those with watery diarrhoea during the post-epidemic years. Higher incidence of shigellosis was observed amongst older children (greater than 3 yr). Most of the shigellosis patients complained of blood and mucus in stools. Vomiting was common among shigellosis patients presenting with watery diarrhoea whereas fever was commonly seen in patients with both dysentery and watery diarrhoea. Most patients of shigellosis presenting with blood and mucus in stools had no dehydration.

Poisoning in children: Indian scenario.

The retrospective data on childhood poisoning from eight regional hospitals in India has been reviewed. The demographic features and types of poisonings encountered have been compared. The analysis of the data indicated that pediatric poisonings constituted 0.23-3.3% of the total poisoning. The mortality ranged from 0.64-11.6% with highest being from Shimla. Accidental poisoning was common involving 50-90% of children below 5 years of age and males outnumbered the females. Suicidal poisoning was seen after 13 years of age and was due to drugs and household chemicals. One of the hospitals in Delhi recorded a very high incidence (66.6%) of drug poisoning in children. The drugs consumed belonged to phenothiazines, antiepileptics and antipyretics. Iron poisoning was seen in younger children. Kerosene was one of the causes of accidental poisoning at all hospitals except Shimla and rural Maharashtra were probably wood charcoal is widely used. Pesticide poisoning was more prevalent in Punjab and West Bengal whereas plant poisoning was very common in Shimla. Significant number of snake envenomation has been recorded from rural Maharashtra. Other less common accidental poisonings in children included alcohol, corrosives, heavy metals, rodenticides, detergents and disinfectants. Thus various regions in the country showed some variation in types and frequency of childhood poisoning which could be attributed to different geographical and socio-economic background.

Effect of protein rich diet during acute phase of dysentery.

Ninety six children upto the age of five years suffering from uncomplicated acute dysentery of less than 3 days' duration were studied to find out the impact of feeding of extra-protein rich diet during their acute phase of illness. These children were randomly allocated to either control group (receiving only hospital diet) and study group (receiving hospital diet and extra milk which constituted 30% of ideal total calorie requirement of patients. Patients in the two groups were comparable on admission. Forty percent reduced food intake was observed among the children of both the groups due to severe anorexia which was reflected by no significant differences in clinical outcome, anthropometrical measurements and haematological parameters between the two groups on day 7 of hospitalisation and on day 15 after discharge.
