视神经炎的临床特征分析及早期视盘和黄斑的改变

目的　研究视神经炎患者的临床特征及早期视盘和黄斑的改变。方法　回顾性分析山西省眼科医院视神经炎患者67例85眼。分析患者基本情况、眼科检查结果及OCT检查结果。结果　67例85眼中，男24例，女43例；28例（41.8%）发生于冬季；49眼（57.6%）入院时最佳矫正视力小于1.7 logMAR。视神经脊髓炎抗体阳性者出院和入院时的最佳矫正视力均较髓鞘少突胶质糖蛋白抗体阳性者差。患眼较健眼视盘周围神经纤维层增厚，杯盘面积比、杯盘垂直比、杯盘水平比、杯容积减小，盘沿面积、视盘面积增大（均为P=0.000）；与健眼相比，患眼早期上方、下方和平均黄斑区神经节细胞层厚度及黄斑区神经节细胞复合体的局部丢失体积、整体丢失体积均未发生明显改变（均为P＞0.05）。视盘水肿与患眼平均视盘周围神经纤维层厚度存在正相关（r=0.728，P=0.000）。结论　视神经炎多发生于女性，早期视力损害严重，视神经脊髓炎抗体阳性者视力预后差。早期由于视盘水肿，视盘周围神经纤维层增厚，盘沿面积、视盘面积增大；杯容积、杯盘比减小，早期病变未累及黄斑区。     

Pain after posterolateral versus nerve-sparing thoracotomy: A randomized trial

Objectives

Post-thoracotomy pain leads to patient discomfort, pulmonary complications, and increased analgesic use. Intercostal nerve injury during thoracotomy or its entrapment during closure can contribute to post-thoracotomy pain. We hypothesized that a modified technique of posterolateral thoracotomy and closure, preserving the intercostal neurovascular bundle, would reduce acute and chronic post-thoracotomy pain.

Intraneural angioleiomyoma of the median nerve presenting as a forearm mass: A case report

Angioleiomyoma is a solitary form of leiomyoma which is typically encountered in the subcutis. They are mostly seen in lower extremities, and the upper extremity is the second most common location for these lesions. There are only a few reports about the presence of an angioleiomyoma within a peripheral nerve in the upper extremity. Here we report a 56-year-old male patient who was referred to our clinic after an attempt was made for removal of a forearm mass at another institution. The lesion was encased within the median nerve and there was an unusual hypervascularity around the tumor with numerous vessels entering the lesion. Removal of the tumor without apparent damage to nerve fascicles was possible. Histopathological examination of the excision material revealed an intraneural angioleiomyoma. Following surgery, the patient was free of any functional deficits and no evidence of recurrence was observed at one year follow-up. There is no data regarding recurrence in intraneural lesions due to the lack of a large series. It would not be wrong to recommend spare grossly uninvolved fascicles if the nerve in question is not expendable.
