RESUMO
Mediastinoscopy was performed for confirmation of the diagnosis in 68 patients who were suspected clinically and radiologically of having sarcoidosis. In 66 of 68 cases in which mediastioscopy was performed a diagnosis was attained. In 35 cases, endobronchial biopsy was performed by bronchoscopy. In only 5 of these (14.2 %) was the diagnosis of sarcoidosis confirmed. The sensitivity of mediastinoscopy was remarkably superior compared with that of endobronchial biopsy. No complication developed with either mediastinoscopy or endobronchial biopsy. In Turkey, mediastinoscopy without any complication costs about 650 USD while bronchoscopy and endobronchial biopsy cost about 150 USD. In our study in which we looked for a histological confirmation -- in the cases suspected of sarcoidosis -- mainly through mediastinoscopy and rarely through other methods (i.e., endobronchial biopsy in one case, skin biopsy in another), we did not come up with a different diagnosis. Therefore, patients suspected of having sarcoidosis should undergo a careful clinical, laboratory, and radiologic examination; they should be under continuous close observation; when necessary (e.g., skin and lip biopsy), the tissue diagnosis should be made by other methods, but if there is the possibility of a disease such as tuberculosis and lymphoma, mediastinoscopy should be performed. The diagnosis of stage 3 sarcoidosis is difficult. For diagnosis, sometimes videothoracoscopy or explorative thoracotomy may be necessary. However, in all our 3 cases with stage 3, we reached the diagnosis of sarcoidosis by the less invasive and less expensive method of mediastinoscopy. Despite our small number of cases, we believe that mediastinoscopy is a very important instrument for diagnosis of stage 3 sarcoidosis.

BACKGROUND: Pulmonary adenocarcinomas constitute a different histological subtype among the histological subtypes of non small cell lung carcinomas by showing comparably unfavourable rates of prognosis and different immunobiological features. Autonomous motility of tumour cells plays an important role in the regulation of local invasion and distant metastasis of tumour lesions which have great impact on overall survival. AMF (Autocrine motility factor) is a tumour secreted cytokine that stimulates motility during invasion and metastasis via its receptor, AMFR. We conducted an immunohistochemical study to investigate AMFR expression in pulmonary adenocarcinomas and its effect on survival. MATERIAL AND METHODS: We assessed AMFR expression using a monoclonal antibody (3F3A) in a total of 32 surgical specimens with stage I pulmonary adenocarcinomas that underwent curative resection. We analyzed AMFR expression as a possible prognostic factor on survival and its correlations with clinicopathological features. RESULTS: A total of 19 (59.3%) specimens showed AMFR expression. The 3-year survival rates of AMFR positive and AMFR negative patients were 47.3% and 84.6%, respectively, which was a significant difference (P = 0.0197). The univariate predictors of surgical outcome were AMFR expression (P = 0.032) and perineural invasion (P = 0.038). However, multivariate analysis revealed AMFR expression (P = 0.045) as the only independent prognostic factor. CONCLUSIONS: AMFR expression predicts an unfavourable surgical outcome in patients with stage I pulmonary adenocarcinomas.

We describe a 39-year-old male patient who developed bleomycin-induced pneumonitis 2 years after completion of chemotherapy for nonseminomatous testicular cancer. Bleomycin sometimes causes fatal pulmonary toxicity, including bleomycin-induced pneumonitis. The central event in the development of pneumonitis is endothelial damage of the lung vasculature due to bleomycin-induced cytokines and free radicals. Pulmonary toxicity usually begins at bleomycin administration. The development of bleomycin-induced pneumonitis up to 6 months after bleomycin therapy has also been reported. We report a patient who developed bleomycin-induced pneumonitis 2 years after the initiation of bleomycin-containing chemotherapy regimens.

Bronchial rupture after intubation with a double-lumen endobronchial tube has been infrequently reported. Overinflation of the bronchial cuff was speculated to be a frequent cause of the bronchial damage. We report the case of a 78-year-old woman with non-small cell carcinoma of the right upper lobe. Her trachea and left main-stem bronchus were intubated with a left-sided polyvinylchloride (PVC) double-lumen endobronchial tube (Broncho-Cath(R) 37 Fr, Mallinckrodth Medical, Athlone, Ireland). She underwent an uneventful right upper lobectomy. At the end of the resection, the surgeons noticed the herniating cuff from the ruptured left main-stem bronchus. Laceration was repaired. Subsequent course of the patient was uneventful: she developed neither bronchial leak nor mediastinitis. Ten days later the patients was discharged home in a satisfactory condition. Factors that seem to increase the risk of injury by a double-lumen tube are discussed.

A 22-year-old woman who had a history of three cardiac operations and a bilateral femoral embolectomy for recurrent cardiac myxoma and myxoma embolism, respectively, was accepted to our clinic with multiple immobile peripheral masses. One of them was compressing the left common femoral artery. This mass was extirpated. Pathology examination revealed myxoma. Chemotherapy was given to the patient and regression of the masses was observed.

A case of primary fibrosarcoma of the heart, which was diagnosed in a 17 year old man, is presented. Extensive tumour resection and postoperative radiation therapy was carried out. The patient is alive after 18 months after the operation. Although these tumours are associated with very poor survival, early diagnosis and combined therapy may prolong life expectancy.
