Survey of Patients with Different Types of Rickets in Fars Province

ABSTRACT There are different causes for rickets. Vitamin D deficiency, disorder in vitamin D metabolism and action, familial x.linked hypophosphatemia, renal failure, hepatic disease & oncogenous rickets are some of the major causes of rickets. In this research we had the opportunity to study 50 cases of rickets during one year period in shiraz. The results showed that vitamin D deficiency was the most common form of rickets. 36 cases (72%) had vitamin D deficiency rickets, 3 cases (6%) had vitamin D dependent rickets and 11 cases (22%) had vitamin D resistant rickets. The sex distribution was (52%) females and 24 (48%) malcs. There was not a significant difference in female to male ratio in this study. We found that 71.4% of patients had used breast milk during infancy and they had not vitamin D supplement. Almost all of them were from cold climate regions of Fars province. Sixteen (32%) of vitamin D deficiency cases were under one year age and they were cared at home. Radiological finding in wrist x. Ray was persent in all patients. The most important symptoms of patients that coming to hospital or office were convulsion and infections especially pneumonia. These results indicate that although several factors are concerned in the development of rickets, the main cause is lack of vit D.
