Vitamin A deficiency among school going children affected by flood

Background: Vitamin A deficiency increases the risk of night blindness and death due to common childhood illnesses that are prevalent during emergencies like floods. The relief diet provided to flood victims is often deficient in micronutrients and minerals including vitamin A. There is a need to assess the levels of vitamin A among flood affected children to prevent morbidity and mortality caused by malnutrition

Objective: To assess the frequency of Vitamin A deficiency among school going children [8-14 years] affected and unaffected by floods of 2010 in district Nowshera

Subjects and Methods: Study was conducted in Government-registered schools situated in flood affected and unaffected areas of district Nowshera of KPK Province of Pakistan. A total of 353 children [8-14 years] were registered for study, including 190 from flood affected and 163 from unaffected areas. A questionnaire was filled for each child which included the demographic information. Three milliliter blood was drawn from each child which was processed for the estimation of vitamin A levels. Data was entered and analyzed using SPSS 20.0

Results: Among flood affected children frequency of vitamin A deficiency was 18.9%, whereas among flood unaffected children it was 6.1% showing strong association with children affected by floods [p < 0.001].Among illnesses during floods, children who had acute respiratory infection were on an average 3.5 times more likely to have vitamin A deficiency as compared to those who did not suffer from this disease [p = 0.037]

Conclusion: Vitamin A deficiency was substantially higher among children affected by floods and those who had acute respiratory infection

Newborn screening for congenital hypothyroidism in a public sector hospital

Congenital hypothyroidism if left untreated results in growth failure, irreversible mental retardation, and cretinism. National neonatal screening programs are therefore, launched to diagnose congenital hypothyroidism and manage it timely. To screen newborns for congenital hypothyroidism in two public sector hospitals of Lahore. Cross sectional descriptive study conducted at departments of Gynae/Obs and Pediatric Shaikh Zayed Hospital and Jinnah Hospital, Lahore from February 2010 to November 2011. Awareness brochures for congenital hypothyroidism were developed and attached with the antenatal card of each pregnant case attending antenatal clinic at Gynae/Obs OPD. Newborns who had stayed in hospital for more than 24 hour, and whose parents consented for heal prick were tested for blood spot thyroid-stimulating hormone. Results were reported within four days and thyroid-stimulating hormone >/= 20mIU/L was taken as high value. Parents of those neonates who had high value were contacted to give a fresh sample for confirmation. Confirmed results were provided within next 4-5 days to the parents and treating pediatrician for appropriate treatment. A total of 1357 samples were screened using blood spot thyroid-stimulating hormone and out of these 1330 were normal [< 20mIU/L] while 27 had high levels [>/= 20mIU/L]. These 27 neonates were further tested using confirmatory tests for serum thyroid-stimulating hormone, T3 and T4. After confirmatory tests only one case had congenital hypothyroidism who was referred for treatment. Three cases were suspected to have subclinical hypothyroidism and these were retested after six months which, picked another case of confirmed subclinical hypothyroidism who was referred for treatment. The incidence of congenital hypothyroidism was 2 out of 1357 cases. The screening could pick 2 cases of hypothyroidism from a total of 1357 cases which is high when compared to global rates. Routine screening of neonates for thyroid disease can pick the disease early and thus prevent later complications
