Tracheal agenesis is a rare and uniformly lethal congenital malformation. It presents with severe respiratory distress at birth. In this anomaly there is a congenital absence of the trachea and the bronchus communicates with the esophagus. The diagnosis should be suspected in newborn infant with respiratory distress whose intubation is impossible. This report describes our experience in two such cases.
Congenital pouch colon (CPC), an unusual high anorectal malformation in which a varying length of colon is replaced by a dilated pouch, has appeared in a number of case reports and series published in the English literature. There is only one case report of its association with prune belly syndrome (also known as triad syndrome, Eagle-Barrett syndrome, and abdominal muscle deficiency syndrome). We report the description and management of this rare association in a male neonate with CPC, prune belly syndrome, and congenital megalourethra.

BACKGROUND AND AIM: In India, approximately 65% of mothers deliver at home, and a community-based study evaluating the cost of vaccinating newborns with the first dose of hepatitis B vaccine within 48 hours has not been undertaken previously. This policy planning study was done to evaluate the costs of such immunization in India. METHODS: All mothers delivering in the study area (population 65,000) over a 1-year period were tested for hepatitis B surface antigen (HBsAg; ELISA), and babies of positive mothers were vaccinated starting at birth. The cost of such selective vaccination was calculated. The cost of nursing time required for universal immunization was calculated from the data on nursing time required for vaccination in the selective vaccination program. The national cost of universal immunization without testing was calculated as well as cost-benefit and cost-utility in terms of cost per quality-adjusted life-year (QALY) saved. Sensitivity testing considering economies of scale was also factored in. RESULTS: 1100 mothers delivered during the study period. 252 were primiparous. Nationwide universal vaccination would cost Rs 48,000 per QALY saved, which was double the per capita GNP of the country; discounted at 3% the cost was Rs 260,000. CONCLUSIONS: Universal immunization vaccination with hepatitis B vaccine is not cost-beneficial in India, since cost of every life-year gained with it will exceed India's per capita GNP.
