ABSTRACT
BACKGROUND: Function of the thoracic sympathetic chain (TSC) reportedly recovers after surgical clips are removed. Hence, this study was designed to study nerve regeneration after unclipping the TSC. METHODS: The bilateral TSCs of six goats were studied; the goats were separated into three groups (groups I, II, and III) during excision, clipping, and unclipping. During surgery, the TSCs were excised with a scalpel in group I and clipped in groups II and III. In group III, the clips were removed 1 month postoperatively and observed for possible nerve healing for 1 month. All TSCs were examined histologically following en block resection at 1 month postoperatively in groups I and II and at 2 months postoperatively in group III. RESULTS: Inflammation in nerve sections was noted following clip removal. Furthermore, there was significant degeneration and cell infiltration in the nerve fibers of the clipped regions. The Schwann cells around the peripheral nerve endings in the unclipped regions facilitated nerve transmission by reconstitution of myelin. CONCLUSION: Clipping the TSC can cause histologic degeneration; however, histologic nerve regeneration occurs after unclipping.

INTRODUCTION: Echinococcosis and/or hydatidosis is one of the most important zoonotic diseases in the world. In Turkey, echinococcosis is an endemic disease, however, hydatid disease of the lung is uncommon and usually caused by Echinococcus granulosus. CASE PRESENTATION: In this report we describe a 17-year-old male patient who presented with massive hemoptysis due to hydatid disease of the lung. CONCLUSION: Although it is one of the less common causes of massive hemoptysis, hydatid disease of the lung requires greater attention in countries, such as Turkey, in which hydatid cyst disease is common.
ABSTRACT
OBJECTIVE: To present a case of endobronchial metastasis from a seminoma mimicking a primary pulmonary mass on X-ray radiograph. CLINICAL PRESENTATION AND INTERVENTION: A 27-year-old man presented with a 1-month history of hemoptysis. Thorax computerized tomography of the patient obtained at the level of the main right bronchi demonstrated a mass with a size of 7 x 6 cm and a peripheral lobulated nodule. Bronchoscopic examination showed narrowing and multiple nodules in the right upper and right intermediary lobar bronchi. Histopathological examination of bronchial biopsies and brushing confirmed endobronchial metastasis of the testicular seminoma. CONCLUSION: This case shows the prognostic significance of distinguishing endobronchial metastasis from primary lung carcinoma.
