Novel nonsense CDC73 mutations in Chinese patients with parathyroid tumors.

Hyperparathyroidism-jaw tumor syndrome (HPT-JT) is an autosomal dominant disease characterized by the occurrences of parathyroid tumors and ossifying fibroma of maxilla/mandible. It is caused by mutations in CDC73 gene and mutation carriers are at increased risk of parathyroid carcinoma. Hyperparathyroidism could be the sole manifestation.

A 7-year-old boy dying of acute encephalopathy.

A 7 year old Chinese boy died of a rapidly progressive encephalopathy after influenza infection. MRI showed bilateral and symmetrical lesions including the thalamus and brainstem tegmentum. The pathology of necrosis and vasculopathy were in keeping with acute necrotizing encephalopathy (ANE).

Results of excision of cerebral radionecrosis: experience in patients treated with radiation therapy for nasopharyngeal carcinoma.

Object: In theory, the purpose of the treatment of cerebral radionecrosis (CRN), a nonneoplastic condition, is to minimize loss of brain function by preventing the progression and reversing some of the processes of CRN. In a practical sense, factors for achieving this purpose may include the following: removal of a CRN lesion that is causing mass effect, control of brain edema, prevention of recurrence of CRN lesions, minimization of adverse effects from treatments, and achievement of reasonably long and good-quality survivals. Based on these practical issues, the authors performed a retrospective study to evaluate the results of excision for the treatment of CRN.
