BACKGROUND: Acute respiratory infections are a leading cause of morbidity and mortality in under-five children in developing countries. Hence, the present study was undertaken to study the various risk factors, clinical profile and outcome of acute lower respiratory tract infections (ALRI) in children aged 2 month to 5 years. OBJECTIVE: clinical features, laboratory assessment and morbidity and mortality pattern associated with acute lower respiratory tract infections in children aged 2 months to 5 years. METHODS: 100 ALRI cases fulfilling WHO criteria for pneumonia, in the age group of 2 month to 5 years were evaluated for clinical profile as per a predesigned proforma in a rural medical college. RESULTS: Of cases 61% were infants and remaining 39%12-60 months age group, males outnumbered females with sex ratio of 1.3;1. Elevated total leukocyte counts for age were observed in only 22% of cases, of these 3% were having pneumonia, 9% severe pneumonia and 10% very severe pneumonia. Significant association was found between leukocytosis and ALRI severity (p=0.0001) Positive blood culture was obtained in 8% of cases and was significantly associated with ALRI severity (p=.0.027). Among the ALRI cases, 84% required oxygen supplementation at any time during the hospital stay and 8% required mechanical ventilation. The mortality rate was 1%; with 99% of cases recovering and getting discharged uneventfully. CONCLUSION: Among the clinical variables, the signs and symptoms of ALRI as per the WHO ARI Control Programme were found in almost all cases. Regarding the laboratory profile, leukocytosis and blood culture positivity were observed in a small percentage, but significant association with ALRI severity was observed for both. Thus, clinical signs, and not invasive blood tests are a better diagnostic tools, though the latter may provide additional therapeutic and prognostic information in severe disease.

Background: Acute respiratory infections are a leading cause of morbidity and mortality in under-five children in developing countries. Hence, the present study was undertaken to study the various demographic risk factors which predispose to acute lower respiratory tract infections (ALRI) in children aged 2 month to 5 year. Objective; Demographic factors associated with acute lower respiratory tract infections in children aged 2 months to 5 years. Methods: 100 ALRI cases fulfilling WHO criteria for pneumonia, in the age group of 2 month to 5 years were evaluated for demographic risk factors and clinical profile as per a predesigned proforma in a rural medical college. Results: Sociodemographic risk factors like parental illiteracy, overcrowding, partial immunisation and low socioeconomic status were potential risk factors; similarly nutritional risk factors like early and late weaning, anaemia and malnutrition were associated with ALRI. Significant environmental risk factors were use of biomass fuels, inadequate ventilation at home, and lack of separate kitchen. Conclusion: The present study has identified various socio-demographic, nutritional and environmental risk factors for ALRI which can be tackled by effective health education of the community and effective training of peripheral health personnel.

We measured serum levels of 25-hydroxy vitamin D (25(OH) D) in 79 preterm neonates (?32 wk), and correlated it with serum ionized calcium (Ca++) levels at 48-72 h and serum phosphorus and alkaline phosphatase levels at 2-3 weeks of age. The mean (SD) 25 (OH)D level was 14.8 (7.0) ng/mL. 25(OH)D levels had a weak positive correlation with Ca++ (r=0.299) and phosphorus (r=0.186), and a negative correlation with alkaline phosphatase (r=-0.523).
