What Tactics Should a Surgeon Choose to Treat a Black Extracerebral Tumor? A Case Report of Psammomatous Melanotic Schwannoma of the Meckel Cave and Literature Review.

Background: Neoplasms located in the Meckel cave account for 0.2%-0.5% of all intracranial tumors.

[Morphological, immunohistochemical and spectral characteristics of dysplasia, preinvasive and invasive forms of lung cancer].

An analysis of modern methods of diagnostics such as morphological, immunohistochemical and spectral, which included the bronchoscopy and spectrometry by using reflectance and autofluorescent regime, was made. The data involved the results of prospective follow-up study of 167 patients (620 biopsies). An obligatory spectrometry of suspicious area was carried out before the forceps biopsy.

[Optimization of treatment methods of surgical complications in lung cancer].

The present report analyses the immediate and long-term results of treatment of surgical complications in 998 patients with lung cancer. There were complications in 37,5% of the cases, with a fatality rate of 14,7%. The most frequent complications were as follows: postoperative empyema with bronchopleural fistula (41,3%), bleeding (12,0%), pneumonia (9,8%), pulmonary arteries embolism (8,1%) and heart rhythm disorders (8,1%).

[Combined endoscopic monitoring of treatment effectiveness in tracheal and/or bronchial malignancies using autofluorescence spectroscopy].

The paper presents our experience with application of a diagnostic procedure which enhanced information potential of endoscopy. Its efficiency increased due to use of an algorithm which included several stages carried out during an endoscopic procedure: routine bronchoscopy, spectroscopy in light (400-700 nm), autofluorescence spectroscopy including nearest infrared spectrum (720-800 nm). During treatment, the latter registered the dynamics of glow intensity ratios in the red (600-680 nm) and green (500-550 nm) spectra.
