UNLABELLED Hypocalcemic cardiomyopathy in infants is characterized by heart failure in a previously normal infant with hypocalcemia without organic cardiac lesion. Vitamin D deficiency rickets is increasing in Middle East. In a six month study 136 cases of rickets were diagnosed in the main Children's Hospital in Almadinah but none of them showed evidence of cardiomyopathy. Concerned of missing...

OBJECTIVE To retrospectively evaluate the epidemic characteristics of children with hypocalcemic convulsion related to nutritional rickets in the province of Kars, Turkey. METHODS In this study, clinical and laboratory findings of 93 infants, aged between 1-24 months, who were diagnosed as hypocalcemic convulsive resulting from nutritional rickets between January 2000 and June 2005 in Kars Ma...

The hypophosphatemic conditions that interfere in bone mineralization comprise many hereditary or acquired diseases, all of them sharing the same pathophysiologic mechanism: reduction in the phosphate reabsorption by the renal tubuli. This process leads to chronic hyperphosphaturia and hypophosphatemia, associated with inappropriately normal or low levels of calcitriol, causing osteomalacia or ...

Nutritional rickets resulting from calcium insufficiency is common in Nigeria and high dietary phytate is thought to inhibit calcium and zinc absorption. We compared the effects of a high-phytate meal and enzymatic dephytinization on calcium and zinc absorption in Nigerian children with and without rickets. Nineteen children with rickets and 15 age-matched control children, aged 2-10 y, were gi...

Background: Metabolic bone diseases (MBD), including rickets and osteopenia, are important neonatal complications among preterm infants. This study aimed to determine the prevalence and risk factors of MBD in neonates with very low birth weight (VLBW). Methods: This prospective study was conducted on VLBW infants from January 2012 to July 2013. Inclusion criteria were birth weight of ≤1500 g a...

A daily 400 IU for is ef...

Children with calcium-deficiency rickets may have increased vitamin D requirements and respond differently to vitamin D(2) and vitamin D(3). Our objective was to compare the metabolism of vitamins D(2) and D(3) in rachitic and control children. We administered an oral single dose of vitamin D(2) or D(3) of 1.25 mg to 49 Nigerian children--28 with active rickets and 21 healthy controls. The prim...

Nutritional rickets (NR) is still the most common form of growing bone disease despite the efforts of health care providers to reduce the incidence of the disease. Today, it is well known that the etiology of NR ranges from isolated vitamin D deficiency (VDD) to isolated calcium deficiency. In Turkey, almost all NR cases result from VDD. Recent evidence suggests that in addition to its short- o...
