A case of congenital toxoplasmosis manifesting as hepatosplenomegaly and cholestatic jaundice in a 4 month old child is reported. To the best of our knowledge this is the first report of cholestatic jaundice due to congenital toxoplasmosis from India. The child was successfully treated with sulphadiazine and pyremethamine combination. [ABSTRACT FROM AUTHOR]

World Health Organization (WHO) recommended standard ORS solution has sodium (90 mmol/L) and glucose (111 mmol/L) almost in the ratio of 1:1 and a total osmolarity of 311 mmol/L. There are concerns that the sodium or glucose concentration and the overall osmolarity in the formulation is not appropriate. Therefore, the efficacy of standard and reduced-osmolarity ORS solutions in young children with acute diarrhea was evaluated in a recent WHO supervised multicentre trial conducted in India (New Delhi), Brazil, Mexico and Peru. The implications of trial results are discussed. In non-cholera diarrhea, both the standard and reduced osmolarity ORS solutions were effective in achieving clinical rehydration. The stool output was 39% higher in the standard ORS solution group as compared to the reduced-osmolarity ORS solution group. The duration of diarrhea was 22% higher in the standard ORS solution group. The risk of requiring supplementary intravenous infusion was increased in children treated with standard ORS solution [relative risk 1.4 (0.9-2.4)]; this benefit was not observed in Indian patients due to high breast feeding rate. The mean sodium concentration at 24 hours after admission was lower in the reduced osmolarity ORS solution group [135 (134-136) vs 138 (136-139), p < 0.01). The low osmolarity ORS deserves to be evaluated in adult cholera to determine its efficacy and any excess hyponatreamia. Meanwhile, it is reassuring that the WHO formulation was effective and its use was not associated with hypenatremia even in young children. Efforts must continue to be made to promote WHO-ORS while research to improve it further is welcome. [ABSTRACT FROM AUTHOR]

In conclusion, vitamin A plays a central role in the regulation of both B-cell and T-cell function acting through gene activation by stimulating transcriptional activity. Correction of vitamin A deficiency, wherever it is prevalent, through immunological and other mechanisms, reduces severity of several important infections. The safety of massive dose vitamin A administration to very young infants with normal vitamin A status must be well established, given some though not substantial evidence of possible effects similar to vitamin A deficiency.

In order to relate etiology of diarrhea to the duration of the episode, a cohort of 452 children up to 36 months of age was visited once weekly at their households for 18 consecutive months to record diarrheal morbidity. Fecal specimens were obtained in 453 diarrheal episodes occurring in 354 children during this period. The common putative agents as single isolations associated with diarrhea were EA-AggEC (17.2%), ETEC (14.1%), EPEC (6.0%) and rotavirus (4.0%). The pathogens with higher median duration of diarrhea were Shigella (13.5; mean +/- SD 13.7 +/- 2.7), Salmonella (8.8: 15.3 +/- 4.5) and EA = AggEC (12.0: 15.1 +/- 1.8). Of 55 episodes with duration of greater than 14 days, the main pathogens isolated were EA-AggEC (32.7%), ETEC (9.0), Salmonella, G. lamblia (5.5% each) and Shigella (3.5%). These data provide a preliminary evidence to suggest that EA = AggEC may well be the main long sought microbial agent responsible for diarrhea of long duration. [ABSTRACT FROM AUTHOR]

The International Cancer Genome Consortium (ICGC) was launched to coordinate large-scale cancer genome studies in tumours from 50 different cancer types and/or subtypes that are of clinical and societal importance across the globe. Systematic studies of more than 25,000 cancer genomes at the genomic, epigenomic and transcriptomic levels will reveal the repertoire of oncogenic mutations, uncover traces of the mutagenic influences, define clinically relevant subtypes for prognosis and therapeutic management, and enable the development of new cancer therapies.

Objective: To compare the acceptability and energy intake of Ready-to-Use Therapeutic Food (RUTF) with cereal legume based khichri among malnourished children. Design: An acceptability trial with cross-over design. Setting: Urban low to middle socioeconomic neighborhoods in Delhi. Subjects: 31 children aged ≥6 to ≥36 months with malnutrition, defined as Weight for height (WHZ) < -2 to &ge - 3 SD, with no clinical signs of infection or edema. Intervention: Children were offered weighed amounts of RUTF and khichri in unlimited amounts for 2 days, one meal of each on both days. Water was fed on demand. Caregivers' interviews and observations were conducted on the second day. Outcome Measures: Acceptability of RUTF compared to khichri based on direct observation and energy intake for test and control meals. Results: The proportion of children who accepted RUTF eagerly was 58% as against 77% for khichri. 42% children on RUTF and 23% on khichri accepted the meal but not eagerly. The median (IQR) energy intake over the two day period in children aged 6 to 36 months from RUTF was 305 (153, 534) kcal, and from khichri was 242 (150, 320) kcal (P=0.02). Conclusion: RUTF and khichri were both well accepted by study children. The energy intake from RUTF was higher due to its extra energy density. [ABSTRACT FROM AUTHOR]

Summary. The literature is conflicting whether or not rotavirus strains with different G serotype have an identical electropherotype. This is a contentious but an important issue because large parts of molecular epidemiological studies of rotaviruses have been based on the conception that a single strain of rotavirus can be defined by a single electropherotype. Here, we examined in detail by reverse-transcription PCR genotyping, electropherotyping, sequencing, and genogrouping using RNA--RNA hybridization three human rotavirus strains isolated in India that had apparently identical electropherotypes although one strain was typed as P[4], G3 while the other two typed as P[4], G2. These three strains showed an identical electropherotype on 7.5% and 12.5% polyacrylamide gels, but co-electrophoresis on a 10% gel demonstrated that segment 8 of the P[4], G3 strain migrated more slowly than the cognate segment of the P[4], G2 strains. Genogrouping assay and nucleotide sequencing provided evidence for the hypothesis that the P[4], G3 stain was an intergenogroup reassortant in which a P[4], G2 strain of the DS-1 genogroup had acquired the VP7 gene from an yet-unidentified concurrently circulating G3 strain. While electropherotyping remains a valuable asset for molecular epidemiology of rotaviruses, this study underscores the importance of co-electrophoresis under different electrophoretic conditions when pinpointing subtle differences.

Rotavirus is the leading cause of childhood diarrhea worldwide, causing an estimated 600,000 deaths each year. To assess the potential benefits of a national rotavirus immunization program in India, we analyzed 40 published studies of rotavirus that were conducted between 1976 and 1997 and included a total of approximately 13,000 Indian pediatric inpatients. Pediatric studies featuring 100 or more patients and lasting at least 12 months in duration and all neonatal studies were analyzed. Rotavirus was detected in a median of 18% of pediatric patients and 28% of neonates surveyed. Fifty percent of all children hospitalized with rotavirus by age 5 were hospitalized by the age of 6 months, 75% by the age of 9 months, and almost 100% by the age of 2 years. Rotavirus was most prevalent (31%) in children between 7 and 12 months of age, followed by children between 1 and 2 years of age (20%), and children < 7 months of age (13%). VP7 genotypes G1 and G2 were most commonly isolated although significant heterogeneity of serotypes was observed. P[11], G9 strains were most frequently isolated among neonates. In 1998; approximately 98,000 childhood deaths were caused by rotavirus. These data underscore the urgent need for safe and effective interventions against rotavirus such as vaccines. The significant diversity of rotavirus strains and young age of hospitalization pose unique challenges to the formulation of a rotavirus immunization program in India, but raise the possibility of utilizing a neonatal vaccine to provide effective coverage.

Two hundred and five cases (mean age 13.4, SD 9.5) of persistent diarrhoea (PD) of 14–28 days duration, attending an urban slum clinic and treated according to standard WHO guidelines, were monitored at weekly intervals to obtain an estimate of treatment failure rates and to identify its clinical predictors. Vitamin and micronutrients (daily 2RDA) were additionally provided. Only 9 (8.2%) of 109 children with criteria for hospital care accepted in-patient care. Weight gain was considered inadequate if the daily increment between enrolment and day 7 of follow up was < 10 g at age 0–3 months, < 5 g at 4–6 months, and any weight loss for those older than 6 months. Recovery was considered delayed if diarrhoea ceased 7 days after enrolment. Overall, 28.3 % cases had inadequate weight gain and 25.6% had delayed recovery. The non-breast milk calorie intake was 11.2 % during infancy and 40.6 % at later ages of the recommended intakes. In a logistic regression model, initial watery stool frequency greater than median (adjusted OR 2.30, p=0.01), age < 6 months (adjusted OR 2.24, p=0.04) and low consumption of micronutrient mixture (adjusted OR 2.62, p=0.01) were associated with an increased risk of delayed recovery. In a Cox proportional hazards model for time to recovery from diarrhoea, low consumption of the micronutrient mixture and age < 6 months reduced the chances of recovery by 29 % and 37 % respectively. Low consumption of the prescribed micronutrient mixture (adjusted OR 2.21, p=0.04), fever (adjusted OR 1.91, p=0.05) and diarrhoea continuing beyond study day 7 (adjusted OR 2.29, p=0.03) increased the risk of inadequate weight gain. Breast feeding status and animal milk consumption did not influence weight gain or recovery. Due to the low compliance for advised hospitalisation, approaches for care at community level itself need to be evolved. Focus should be on increasing the overall dietary intake and provision of generous but safe amount of micronutrients; our findings do not support need for routine elimination of animal milk. The efficacy of individual micronutrients needs evaluation in controlled trials. [ABSTRACT FROM AUTHOR]

The national Diarrheal Disease Control Program was launched with the aim of improving the knowledge and practice of appropriate case management among caretakers of young children as well as health care providers. The National Family Health Survey (1992-3) revealed that 42.7% of mothers knew about ORS packets and 25.9% had ever used them. ORS use rates in children who suffered from diarrhea during the previous two weeks varied from 8.3% in Rajasthan to 50.1% in West Bengal. These findings represent substantial accomplishment, and also are a reminder that we still have to reach more than half of the households. Further analysis of the NFHS data showed that exposure to electronic mass media had a significant impact on mothers' awareness about ORS packets (56% in exposed, 32% in unexposed) and ORT use rates (38% in exposed, 25% in unexposed). In this review, future strategies for increasing the impact of the program are discussed. These include involvement of licensed and unlicensed medical practitioners, greater use of the electronic mass media, ORS standardization, greater focus on poorly performing states and resolving residual issues in the case management of diarrhea in malnourished children and infants under 6 months of age.

In an empiric approach to develop the definition of persistent diarrhea, we evaluated the relationship between diarrheal duration and risk of ensuing clinically significant decline in nutritional status, in a cohort of 395 children < 24 mo. Weights were obtained at the onset of diarrhea (wt I) and after three months interval (wt II). The occurrence of an adverse outcome (AO) was defined as a decline of -- 5% in NCHS weight for age (% WFA) between weights I and II or death in this interval. The risk of AO was similar for episodes of / or > 7 days while it was substantially higher in episodes with > 14 days duration (45%) than for shorter duration episodes, relative risk (RR) = 2.5 (p < 0.001). Relative risk remained similar for duration thresholds of 21 (2.3) and 28 days (2.6). As episode durations greater than 14 days are associated with substantial elevation of the risk of clinically cogent sequelae, such episodes may be termed 'persistent' at least in terms of poor prognostic expectations.

A total of 157 infants and preshool children with acute diarrhea were investigated for Yersinia enterocolitica over a six months period. Only one infant with acute diarrhea (0.6%) was found to have Yersinia enterocolitica in the stool as compared to none from the 65 asymptomatic controls. Clinical features of the child with yersinia diarrhea have been described. [ABSTRACT FROM AUTHOR]

Lactose tolerance test (LTT) was performed in 70 children with idiopathic recurrent abdominal pain (IRAP) and 50 matched controls. The prevalence of lactose malabsorption in the IRAP patients (47.1%) was significantly higher than in controls (18%). When milk was withheld for a 4 week period, 33% (11/33) of lactose malabsorbers and 16.2% (6/37) of lactose absorbers were relieved of their symptoms, the difference being insignificant. The limitations of standard oral lactose tolerance test are discussed. [ABSTRACT FROM AUTHOR]
