Abstract: Five children with chronic renal failure and severe rachitic deformities of the lower limbs were treated with 1 alpha-hydroxyvitamin D (1 alpha-OHD3) for 16 to 53 months. There was symptomatic, biochemical and radiological improvement in all five children and operative correction of their deformities was not needed. We recommend a trial of treatment with 1 alpha-OHD3 for this condition before surgical procedures.

question:
Abstract: Thermal injuries lead to changes in both the cell-mediated and humoral responses of the patient. This study was undertaken to assess these responses in the post-burn period and also to see if bacterial infection altered these responses. It has been concluded that alterations in the cell-mediated and humoral immune responses following thermal injuries are altered by infection and consequently are also important in the healing process.

Abstract: Repetitive chest pain of obscure origin is commonly encountered in older children and adolescents. A questionnaire study was conducted to determine the long-term outcome in 31 patients diagnosed as having idiopathic recurrent chest pain after an average 4.1-year follow-up period. Although 45 percent reported having had persistent symptoms, chest pain had disappeared in 81 percent of those followed more than 3 years. Equally reassuring is the fact that in no case did occult disease subsequently appear to account for the initial symptoms. This study supports the current clinical approach of limited diagnostic evaluation and reassurance in the management of these patients.
