BACKGROUND In the Sub Saharan Africa Rickets has now been established to be due primarily to calcium deficiency and sometimes in combination with vitamin D deficiency. The main thrust of management is calcium supplementation with or without vitamin D. An observation was made that some children with nutritional rickets do not respond to this management modality. The recently reported high preval...

Vitamin D resistant rickets with alopecia is a rather rare heritable disease probably caused by a different variety of metabolic disorder of this vitamin. Disturbances of protoplasmic and unclear receptors for vitamin D metabolites in bones and intestinal cells have been proposed as basic mechanism; Alopecia is attributed to hypersensitivity to vitamin D; very much like what usually appears in ...

Recent case reports highlight the resurgence of rickets in certain groups of breastfed infants. Infants residing in the North, irrespective of skin color, and dark-skinned African American infants residing anywhere in the United States are most vulnerable to nutritional rickets if they are exclusively breastfed past age 6 months without vitamin D supplementation. At the turn of the 20th century...

A 10-year-old boy, with widespread soft tissue tumours of bone, developed hypophosphataemic rickets due to impaired renal tubular reabsorption of phosphate. Biopsy of the largest tumour showed a nonosteogenic fibroma. We believe this boy is another example of 'tumour rickets', as other causes of rickets were excluded clinically and biochemically. Cases of rickets or osteomalacia associated with...

Vitamin D deficiency rickets is a childhood osteomalacia, with impaired skeletal development and potentially skeletal deformities. The radiographic findings of rickets are many but include widening, fraying, and cupping of the metaphysis. Developmental delay and related complications of seizure and tetany have also been reported. This medical entity is often thought of as a classic medical dise...

BACKGROUND Rickets and vitamin D deficiency appeared to increase in Alaskan children starting in the 1990s. We evaluated the epidemiology of rickets and vitamin D deficiency in Alaska native (AN) children in 2001-2010. METHODS We analyzed 2001-2010 visits with rickets or vitamin D deficiency diagnosis for AN and American Indian children and the general US population aged <10 years. We conduct...
