Bronchoscopic aspects of renal cell carcinoma (RCC).

A symposium on RCC in July 1998 in Tübingen was where we to reviewed our patients with endobronchial metastatic RCC treated by bronchoscopy since 1981. 24 of 26 consecutive cases are the subject of the present study. Tumor history, X-ray findings, endobronchial appearance, treatment and the pathogenetic mechanisms of this special form of metastatic spread are demonstrated and discussed. In 5 patients > 10 years relapsed between nephrectomy and bronchoscopic tumor therapy. A thrombuslike tumor growth and bleeding were striking bronchoscopic features. In X-ray besides atelectasis, hilar or mediastinal masses were seen half of the patients, in 50% without parenchymal lung nodes, suggesting lymphogenic spread. In several patients bronchial recanalisation could be successfully repeated over long periods. Abnormal X-ray, haemoptysis or dyspnoa in patients with RCC demands bronchoscopy. In case of bronchial tumor obstruction bronchoscopic treatment offers excellent palliation.

Perioperative brachytherapy as an additional therapeutic option in patients with renal cell carcinoma (RCC), either inoperable or after completed percutaneous radiotherapy.

Between January 1992 and December 1997 60 patients with different tumors were treated with perioperative high dose rate brachytherapy with Iridium 192 in afterloading technique (HDR), total dosis 20-30 Gy. Three of the patients had RCC. These patients are presented in detail. In elected patients in whom other forms of treatment are not available or have failed, the method offers an additional therapeutic option and can achieve excellent results.

Scanning electron microscopy in medico-legal investigations of hair.

The appearance of the hair surface as revealed by scanning electron microscopy is described. Intact human and animal hair, hair after shot and hair treated with thermic energy were the subject of investigation. The authors paid attention to numerous details of the pictures obtained due to high resolving power of scanning electron microscope.
