It is characterized by hemorrhagic gingivitis, subperiosteal hemorrhages,perifollicular hemorrhages, and frequently petechia hemorrhages(especially on the feet). People with abnormal dietary habits, mental illness or physical disability are prone to develop this disease. Epiphysea separation is known to occur in scurvy but is rarely seen now. Epiphyseal separation from the metaphysis is always through the zone of calcified cartilage,known as "scorbutic lattice", which in the radiographs is represented as "the white line of Frenkel". We report a case of multiple epiphyseal separations in a cerebra palsy child because of vitamin C deficiency. The child was treated with splintage of extremity and nutritiona supplementation. All physeal separation healed completely without any deformity.展开更多

Only 0.1 percent of all ovarian tumours and 4 - 5 percent of granulosa cell tumours present as JGCT. The most common presentation of these tumours in children is precocious puberty. We describe anaesthetic management of a case of JGCT in a 1-year-old girl. The malignancy is assigned to International Federation of Gynaecology and Obstetrics staging system (FIGO stage I). It was treated with complete excision and histological examination confirmed the diagnosis.展开更多
