Ice skating is a community-based sport and a popular leisure activity that can also have benefits for people with disabilities. Ice skating and children with hearing impairment: Self-concept, behavioural and emotional problems, and sleep quality of the children with hearing impairment significantly improved after ice skating. Ice skating programmes may be considered as a rehabilitation alternative for children with hearing impairment. Ice skating and children with visual impairment: Caution must be use when including children with visual impairment in ice skating programmes because of possible negative psychological outcomes. Balance exercises before starting the practices on ice should be considered for preventing some possible negative outcomes in children with visual impairment.

The aim of this study was to determine the effects of vitamin E (VE) and L-carnitine (LC) supplementation, separately or in combination, on radiation-induced oral mucositis and myelosuppression. Group 1 received no treatment (control). Group 2 received 15 Gray of 60Co gamma irradiation as a single dose to total cranium (IR). Group 3, 4, and 5 received irradiation plus 40 mg/kg/day VE (IR+VE) or 200 mg/kg/day LC (IR+LC) or in combination (IR+VE+LC) respectively. Clinically and histopathologically, assessments of mucosal reactions were performed by two independent experts in Radiation Oncology and Pathology, respectively. Hematologic analyses and antioxidant enzyme evaluations were also performed. Irradiation significantly increased oral mucositis, and decreased thrombocyte and White Blood Cell counts. A significant increase in malondialdehyde (MDA) levels and decrease in superoxide dismutase (SOD) and catalase (CAT) activities in plasma were found in the IR group. VE and LC administration, separately, plus irradiation significantly delayed the starting day, and reduced the severity of, oral mucositis. This administration also reduced a fall in the numbers of thrombocyte and WBC caused by irradiation, and decreased the MDA level, and increased the activity of SOD and CAT enzymes in the plasma. VE and LC, in combination, plus irradiation did not provide a superior radioprotection against radiation-induced toxicities.

For children undergoing tonsillectomy, intraoperative subhypnotic propofol infusion combined with dexamethasone treatment provides a better prophylaxis against postoperative vomiting than does dexamethasone alone.

Primary hyperparathyroidism is a fairly frequent pathologic diagnosis characterized by hypersecretion of parathyroid hormone, which results from adenomas in 80% to 85% of all cases. At clinical onset, the most common symptoms are hypercalcemia-related and some of them are pain due to kidney stones, polyuria, gastrointestinal, and neurologic disorders, whereas rarer symptoms are due to brown tumors and expansive lesions often found in fibrocystic osteitis. Brown tumors represent the terminal stage of the remodeling processes caused by an increased osteoclastic activity and fibroblastic proliferation during primary or secondary, albeit more seldom, hyperparathyroidism. The manifestation of primary hyperparathyroidism as skeletal disease has nearly disappeared in the last 2 decades. Cases are now most often diagnosed by the coincidental finding of asymptomatic hypercalcemia. Advanced screening techniques have made clinical evidence of bone disease rare. This article contains a case of brown tumor on the maxilla, palate, and mandible in addition to nephrectomy and proximal femur fracture, which are probably associated with primary hyperparathyroidism although less common nowadays. The diagnosis was suggested by the clinical history and confirmed by biochemical, radiologic, and histopathologic evidence. Excision of a parathyroid adenoma normalization of the metabolic status was then realized.
