Vitamin-D-deficiency rickets in Kuwait: the prevalence of a preventable disease.
Two hundred and fifty children with clinical , biochemical and radiological evidence of vitamin-D-deficiency rickets were studied over a period of 5 years . Their ages ranged from 1 month to 2 years . Breastfed infants formed 63 % of total cases . Intramuscular therapy with vitamin D in a dose of 600,000 IU , deep intramuscular , proved to be safe and effective . In contrast , oral vitamin D did not provide such satisfactory results , presumably owing to poor patient/parental compliance . This report reveals that vitamin-D-deficieny rickets is common in Kuwait in spite of abundant sunlight all through the year because children are wrapped up and kept indoors . Insufficient intake of vitamin D is another important factor in the pathogenesis of vitamin-D-deficiency rickets in Kuwait
