The association of neural tube defects (NTDs) with Down syndrome (trisomy 21) and altered folate metabolism in both mother and affected offspring provide a unique opportunity for insight into the etiologic role of folate deficiency in these congenital anomalies. We describe here the case of a male child with trisomy 21, cervical meningomyelocele, agenesis(More)
R ickets is often considered a 19th century disease. However, despite the availability of vitamin D and demonstration of its efficacy in preventing rickets, vitamin D deficiency rickets still exists as a public health problem with significant morbidity in the Middle East and in many Asian countries, 7 and has been reported with increasing prevalence in(More)
OBJECTIVE The aim of this study was to determine the level of knowledge and use of periconceptional folic acid supplementation in a sample of postpartum women recruited from three hospitals. DESIGN Cross-sectional survey in which a structured questionnaire was used in a face-to-face encounter between the subject and a trained nurse. SETTINGS Two(More)
OBJECTIVE To determine the prevalence of hypovitaminosis D in exclusively breast-feeding infants and their mothers in a community where maternal sunshine exposure is low. STUDY DESIGN Serum levels of calcium, phosphate, alkaline phosphatase, 25-hydroxy vitamin D (25-OHD), and intact parathyroid hormone were measured in 90 unsupplemented healthy term(More)
The aim of this study was to establish the profile of major congenital malformations in the United Arab Emirates (UAE) population which has a high rate of consanguinity. All births with birth weight above 500 g in the three hospitals in the Al Ain Medical District of UAE were prospectively studied from January 1992 to January 1994. About 98% of the births(More)
We report the findings of a total population survey of Thugbah community in the Eastern Province of Saudi Arabia (SA) to determine its point prevalence of neurological diseases. During this two-phase door-to-door study, all Saudi nationals living in Thugbah were first screened by trained interviewers using a pretested questionnaire (sensitivity 98%,(More)
Low serum 25-OHD in female Arab subjects, which may predispose their infants to hypocalcaemia, has been suggested to be due to inadequate sunshine exposure, but may include other sociobiological factors. The effects of duration of sunshine exposure--weighted against the magnitude of clothing (UV exposure) and other sociobiological variables such as age,(More)
There is increasing evidence that cerebral palsy (CP) in developed countries results mainly from antenatal factors, whereas reports from developing countries suggest that perinatal and postnatal factors may be more important because of less than optimal delivery conditions. The authors studied 103 Saudi children with CP and compared their antecedent factors(More)
Severe vitamin D deficiency in mothers and their breastfed infants is a significant health problem in the Middle East. Supplementation of the breastfed infant alone with the recommended dose of vitamin D may be insufficient in high-risk population. We investigated the effect of combined maternal and infant vitamin D supplementation on vitamin D status of(More)
Vitamin C and D levels in Arab women and their newborn infants have been shown to be low. We investigated the prevalence of and risk factors for possible hypovitaminosis C and D in a convenience sample of 51 hospitalized children without clinical features of vitamin C or D deficiency. The mean age was 15.4 months. The serum vitamin C concentration was low(More)
