Growth and sexual maturation of low birth weight children: a 14 year follow up.

OBJECTIVE: To evaluate the physical growth and sexual maturation of children born with low birth weight (< 2000 g). (LBW). DESIGN: Longitudinal follow up. SETTING: Hospital born urban cohort. METHODS: Weight, height, head circumference and pubertal changes were recorded till 14 years at specified intervals in 252 LBW and 176 control (term neonates with birth weights > or = 2500 g) children. Effect of prematurity and fetal growth retardation (SFD) was studied in 79 preterm appropriate for gestation and 45 term SFD children. RESULTS: LBW boys significantly lagged behind their controls for all physical growth parameters till 14 years, while the LBW girls had a physical growth comparable to controls after 11 years. Preterms had comparable weight, height and head circumference with their controls after 11 years. The SFDs, however, remained significantly handicapped in their overall physical growth even at 14 years. In comparison to controls, menarche occured 6 months earlier in preterms and 12 months earlier in SFD girls. However, there was no change in the sequence of pubertal changes in either preterms or SFDs. CONCLUSIONS: Fetal growth retardation has a lasting adverse effect on later physical growth, while most preterms catch up with their peers by adolescence.

Breast-feeding practices in Schedule Caste communities in Haryana state.

A study was conducted to assess exclusive breast-feeding, continued breast-feeding, bottle-feeding, predominant breast-feeding, timely complementary feeding and other breast-feeding practices in 818 children in the age group of 0-3 years belonging to the Schedule Caste communities of Haryana. The exclusive breast-feeding rate was 0.15 and the predominant breast-feeding rate 0.75 in children < 4 months. Timely complementary feeding rate was 0.42. The continued breast-feeding rate at 1 year and 2 years was 0.84 and 0.58, respectively. The bottle-feeding rate, ever breast-fed rate, timely first-suckling rate and exclusive breast-feeding rate by mother were 0.09, 1.0, 0.0 and 0.15, respectively. The median duration of breast-feeding was 16 months.

Simple predictors to differentiate acute asthma from ARI in children: implications for refining case management in the ARI Control Programme.

There is a considerable overlap in the clinical presentation of acute asthma and ARI. According to the current ARI Control Programme recommendations, a child with cough and rapid breathing is overtreated for ARI (pneumonia) with antibiotics and undertreated for asthma with bronchodilators. The present study, therefore, evaluated simple predictors to differentiate these two conditions to refine the recommended case management. In a case control comparison, children between 6 to 60 months age who presented with cough and rapid breathing due to acute asthma (n = 100) and ARI (n = 100) were evaluated. Only 34% of asthmatics had an audible wheeze. Significant independent predictors on multiple logistic regression analysis were number of earlier similar attacks and fever (or temperature). The best predictor for asthma was two or more earlier similar episodes (sensitivity 84%, specificity 84%) followed by temperature < 37.6 degrees C (sensitivity 73% and specificity 84%). Absence of fever, audible wheeze and a family history of asthma had excellent specificities (98-100%) but low sensitivities (20-34%). It is concluded that simple clinical predictors can differentiate acute asthma and ARI. The recommended case management can, therefore, be refined by either: (i) Prescribing bronchodilators and no antibiotics with two or more earlier similar episodes of cough and rapid breathing; or (ii) To further minimize undertreatment for pneumonia, prescribing bronchodilators as above, but denying antibiotics in such cases only if there is audible wheeze or family history of asthma or no fever.

Clinical predictors of hospitalization in an acute attack of bronchial asthma.

The present study was undertaken to identify the clinical predictors of hospitalization in an acute attack of bronchial asthma in subjects aged 2-12 years. Seventy five children with an acute attack of bronchial asthma were evaluated. A detailed clinical history and examination was recorded and baseline investigations sent before starting therapy. All subjects were treated with injection adrenaline (two doses) and those who did not respond were hospitalized. Twenty subjects who were hospitalized were compared with 32 cases who were discharged and did not have a relapse on follow up. After multivariate analysis, the factors independently predictive of hospitalization were, pulsus paradoxus (> 10 mm Hg; OR = 1.02), younger age (below 5 years, OR = 0.98) and severe accessory muscle use (OR = 89.6). Presence of any 2 of these 3 clinical predictors has a high sensitivity (90%) and specificity (96%). The investigative variables significant after multivariate analysis were low pH (OR = 0.00) and polymorphonuclear leucocytosis (> 70%) on peripheral smear (OR = 1.12). The sensitivity of this model was similar (90%) but specificity was lower (90.6%). The addition of investigative variables to clinical model did not improve the predictability. It is concluded that it is possible to identify at presentation, children with acute bronchial asthma who require hospitalization and clinical variables are sufficient for this purpose.

Rectal histopathology in endemic Shigella and Salmonella diarrhea.

Rectal histopathology was evaluated in 34 cases (2 months-12 yrs old) of endemic "invasive diarrhea" [> 20 WBCs per high-power field on stool microscopy with (RBC positive) or without (RBC negative) associated RBCs] where S. dysenteriae (n = 9), S. flexneri (n = 11), and nontyphoidal Salmonella were isolated as the sole identifiable enteropathogens. Persistent diarrhea (> 14 days duration) was more common with Salmonella infection whereas RBC-positive "invasive diarrhea" was more frequent with Shigella, particularly S. dysenteriae (all cases) infection. The histopathological profile was comparable to the earlier descriptions of infective colitis to a large extent and the nature of the infecting organism could not be determined on the basis of rectal histology alone. The other noteworthy features were as follows: (i) mild crypt distortion (26%) and branching (21%) in both Shigella and Salmonella infection; in Salmonella infection, dilation of the glands was significantly greater with persistent diarrhea; (ii) presence of chronic inflammatory cells either alone or in combination with neutrophils in 62%; a predominant neutrophilic response was significantly higher with S. dysenteriae infection and an acute presentation; (iii) pseudomembrane formation (six subjects; 18%) especially in S. dysenteriae (four cases); and (iv) a significant association of neutrophilic response, edema, and neutrophils within the vessels in the lamina propria and mucin depletion in the glands with RBC-positive "invasive diarrhea."

Classification of nutritional status as 'Z score' or per cent of reference median--does it alter mortality prediction in malnourished children?

The objective of the study was to evaluate, using a prospective cohort study, whether classification of nutritional status by 'Z score' or per cent of reference median alters the prediction of death in malnourished children. The subjects were children with diarrhoea requiring hospitalization due to moderate or severe dehydration and/or associated complications. There were 382 participants under 5 years of age, of whom 37 died (cases), 320 were discharged in a satisfactory condition (controls) and 25 left before diarrhoea was completely cured (lost to follow-up--excluded). Rehydrated weight and recumbent length (under 2 years) or standing height were recorded and the three indices (weight for age, height for age and weight for height) derived as both 'Z scores' and per cents of reference National Centre for Health Statistics (NCHS) medians. Logistic regression, sensitivity specificity curves and Zda test for normalized distances were used to compare the relative utility of these two classification methods in identifying children with a high risk of dying. The per cent of reference median and 'Z scores' were highly correlated (r = 0.9540, 0.9787 and 0.9667, respectively). Both methods yielded virtually identical results in predicting death of malnourished children for all the three indices. It was concluded that 'Z score' and per cent classification of nutrition are equally efficient in predicting death of malnourished children.

Commercial oral rehydration solutions--pitfalls, knowledge, attitude and practices.

Locally available commercial preparations of oral rehydration solutions (ORS) were analyzed for their composition, package instructions and availability. A survey from 50 chemist stores, revealed that ORS packets available belonged to 28 different pharmaceutical companies. None of the shops stored more than five different brands and alternate preparations were handed over the counter freely. Only 48% of the available ORS formulations had the WHO recommended composition. In about one-fourth preparations, the sodium concentration was 30 mEq or less per litre. Forty-one per cent solutions had glucose concentrations more than 2%. The glucose and sodium ration of 1:1 was maintained in only 48% of the formulae. Bicarbonate and citrate both were used with almost equal frequency in these preparations. Cost, flavor, additional ingredients and package instructions varied widely in different packets. ORS formulations most commonly found in the drug stores had low sodium and high glucose concentration. The attitude of doctors and nurses of Pediatric Department and Chemists towards commercial ORS was also studied. While 92% doctors were aware about WHO-ORS, none of the chemists and only 4% nurses had this awareness. All the respondents could remember only up to 3 or 4 brand names and except 30% doctors, none were aware about the composition of those brands of ORS. Regarding importance of composition, preparations and precautions, practically nobody was up to the mark, but doctors were definitely better as compared to nurses and chemists.

Clinical and etiological profile of acute viral hepatitis.

There is a paucity of data on the incidence of sporadic viral hepatitis in Indian children. Clinical, biochemical and etiological profile of 54 patients with acute viral hepatitis was evaluated. Of these, 32 (59.25%) patients had Hepatitis A, 18 (33.33%) had NANB, 2 (3.7%) had Hepatitis B and 2 (3.7%) concurrent Hepatitis A and B infection. It was not possible to distinguish the etiological agents on the basis of the clinical and biochemical profile. Fulminant hepatitis was documented in 8 (14.8%) cases. Children with NANB infection were at a greater risk (p less than 0.05) of developing fulminant hepatitis as compared to Hepatitis A infection.

Impact of national immunization schedule on vaccine preventable diseases: a hospital based study.

An analysis of vaccine preventable diseases (VPD) in two block years, i.e., 1972-1975 and 1986-1989 showed an overall decline in morbidity and mortality. Improvement in morbidity was most noticeable in typhoid fever followed by polio and tetanus. However, in tuberculosis and measles with compilations, there was a significant increase in admission rates 3.8 vs 4.4% and 1.8 vs 2.2%, respectively. Mortality in vaccine preventable diseases except polio has declined significantly.

Water supplementation in exclusively breastfed infants during summer in the tropics.

This study was designed to determine the need for water supplementation to maintain water homoeostasis in exclusively breastfed infants during summer in a tropical country. A prestudy questionnaire revealed that 97% of 34 nurses and 63% of 70 doctors advocated such supplementation. 45 healthy, male, exclusively breastfed babies, aged 1-4 months, were recruited from a well-baby clinic. 9 who had never received supplemental water plus a random selection of 14 others were allocated to group I (breastmilk only); the remaining 22 infants were allocated to group II (breastmilk plus supplemental fluid according to the mother's usual practice). The babies were studied at the hospital for 8 h; breastmilk intake was measured by weighing the infant before and after each feed, water intake by calibrated bottles, and urine output by accurate collection and measurement. The maximum room temperatures were 34-41 degrees C and relative humidities 9-60% (below 50% in all but 3 infants). In group II the mean water intake was 11% (95% confidence interval 7-16%) of the total fluid intake. Both breastmilk intake (274 vs 210 ml) and total fluid intake (274 vs 233 ml) were higher in group I than in group II (p = 0.003, p = 0.073, respectively), after adjustment for age, weight, length, room temperature, and humidity. However, there were no significant differences between the groups in urine output, urine or serum osmolality, weight change, or rectal temperature whether or not the factors adjusted for included total fluid intake. Thus, exclusively breastfed infants do not need supplemental water to maintain water homoeostasis; a reduced breastmilk intake is a potential disadvantage of this practice.

Reversible computerized tomographic lesion following childhood seizures.

Recently reversible computerized tomographic (CT) lesions following seizures have been reported, mostly in adult subjects. Focal CT lesions following seizures were recorded in 20 children. The distribution of the lesions was parietal in 17, frontal in two, occipital in one, and temporo-parietal in one. Multiple simultaneous lesions were observed in one child. Plain scan revealed evidence of cerebral oedema in 16 patients (mild 10, moderate four, and severe two). Enhanced scan showed a ring lesion in 12, hyperdense focus in five, and non-enhancing (hypodense) lesion in two children (excluding one child who had multiple lesions; three rings and one dense focus). These subjects were treated with anti-epileptic drugs only. Repeat CT scans yielded a complete resolution in 12 and a significant resolution in eight. It is concluded that in children with seizures, reversible CT demonstrable focal abnormalities may occur.
