The informative value of the criteria of cytological diagnostics of tumors of the thyroid gland

The authors present a comparative analysis of preoperative cytological investigation of 65 bioptates of the thyroid gland obtained by the method of fine-needle aspiration puncture biopsy and smears-prints of the same tumors made during the operation. The analysis was made according to 10 cytological criteria. The degree of correspondence of the cytological and histological investigations was determined in nodular goiter and carcinomas of the thyroid gland. The maximal specificity and sensitivity was noted in capillary carcinoma (95.3% and 100% respectively).     

Clinico-morphological characteristics of pulmonary mycobacteriosis

According to the criteria of the American Thoracal Societypulmonary mycobacteriosis has been diagnosed at 40patients without clinically important immunosupression (MAC--35%, Mkansasii--25%, M. xenopi--20%, M. fortuitum--12.5% and M. chelonae--7.5%). 95% patients have had clinically important symptomatology with polymorphic radiologic development such as a deformation of a lung pattern and focal dissemination (75%), locus and infiltration (52.5%), cavities (42.5%), marked pneumosclerosis (60%) and bronchiectasis (17.5%). 75% patients have had some changes of the bronhial tree. As opposed to tuberculosis the morphology of mycobacteriosis is more homogeneous and includes inflammation with epithelioid giant-cell granuloma and fibrosis, pneumogenic and bronchogenic cavernous cavities, mycobacterial endobronchitis. The polymorphism of clinic-radiologic developments, a similarity of lung diseases morphology caused by nontuberculous mycobacteria makes difficulties to diagnose theirs.
