[Cytologic differential diagnosis of various peripheral lung cancers].

The data on 25 cases of histologically verified bronchioloalveolar carcinoma and papillary adenocarcinoma are discussed. Reliable differential diagnostic cytological features of both diseases were established using a statistical, program and fine-needle biopsy findings. Statistical analysis data pointed to the sets of cytological features: "serial pattern--clear cell boundaries" and "serial pattern--presence of macrovacuoles" as a major factor of accuracy of bronchiolo-alveolar carcinoma and papillary adenocarcinoma diagnosis.

[Cytological differential diagnosis of different variants of peripheral lung tumors].

Cytological differential diagnostic features of bronchiolo-alveolar carcinoma and papillary adenocarcinoma are established basing on the material of needle biopsies by means of Statistica program. It is found that the strongest influence on the cytological diagnosis of these two tumors is associated with the following pairs of cytological features: lane--clear-cut cell borders and lane--the presence of macrovacuoles.

[Feasibility of pre-operative cytologic diagnosis of pathologic processes in the breast].

Results are available of clinical and cytological diagnosis for 200 patients with histologically established benign lesions of the mammary gland. The use of cytological method at the presurgery stage decreases the number of unjustified carcinoma suspects up to 5%. True cytological diagnosis is established in 90% of mastopathies, 84.

[The effect of angiotensin-converting enzyme inhibitors on left ventricular hypertrophy in patients with chronic glomerulonephritis and pronounced kidney failure].

This study compared the effects of angiotensin converting enzyme (ACE) inhibitors captopril versus enalapril on left ventricular (LV) muscle mass and LV systolic and diastolic function in 58 patients with primary glomerulonephritis and moderate chronic renal failure. The design was a 6-8 week titration phase and 6-month maintenance phase. Mean myocardial mass calculated by M-mode echocardiography in the captopril group was 153 +/- 26 g/m2 before, and 130 +/- 14 g/m2 after 6 months of treatment, in enalapril group 147 +/- 22 g/m2 before, and 126 +/- 23 g/m2 after 6 months of treatment (p < 0.

[Urgent morphologic diagnosis of tracheal tumors in the course of roentgeno-endoscopic study].

84 tracheal tumors the correct diagnosis of which was established during roentgenoendoscopical investigation combined with urgent cytological diagnosis are reported. Cytological fast diagnosis can be considered a reliable method of morphological diagnostics.

[Carcinoid tumors of the lung].

Detailed cytological, histological and electron microscopic characteristics of pulmonary carcinoid tumors are listed on the basis of surgical clinic material. Various variants of the carcinoid tumors structure, their differential diagnosis are presented.

[Possibilities of various diagnostic methods in the assessment of the state of axillary lymph nodes in breast cancer].

The incidence of axillary lymph nodal metastases in breast cancer is proportional to the size of a focus: To is 25 +/- 25%, T1-33 +/- 17%, T2-55 +/- 7%, T3-65 +/- 11%, the choice of the optimum treatment regimen requires more accurate preoperative detection of metastatic lymph nodes. Ultrasound technique (its accuracy is 80%, sensitivity-88%) is of the most diagnostic value in the detection of metastatic lymph nodes. The absence of echographic signs supports the nonspecific nature of changes.

[The clinico-morphological characteristics and treatment of minimal-change glomerulonephritis and focal-segmental glomerulosclerosis-hyalinosis].

Clinical and morphological features were analysed of the morbid condition in 46 patients with glomerulonephritis presenting with minimal alterations (GNMA) and 12 those with focal-and-segmental glomerulosclerosis-hyalinosis (FSGH), of whom there were twenty nine males and twenty nine females ranging between 15 to 54 years. In all cases morphologic diagnosis was established on the basis of vital histologic investigation of renal tissue. Immediate results were assessed of glucocorticoid and cytostatic therapy instituted at different stages of the condition.

[The differential diagnosis of peripheral lung formations (cytological research)].

The following pulmonary lesions were studied: carcinoma, carcinoid, tuberculoma, chondromatous hamartoma, chronic non-specific inflammatory process. Material was obtained through fiber bronchoscopy and roentgeno-endoscopical examination. Pappenheim staining in the modification of Astrakhantsev-Nechaeva and Ziehl-Neelsen staining were used.

[Left ventricular hypertrophy in patients with nephrogenic arterial hypertension].

Incidence and geometric peculiarities of hypertrophy of the left ventricle of the heart (HLVH) were studied on the basis of findings from the echocardiographic investigation done in 86 patients with chronic glomerulonephritis (ChGN) with arterial hypertension (AH), with the renal function being preserved and at the early stages of renal insufficiency. HLVH was detected in 30.2% of the patients, in 80.

[The characteristics of hematuria in chronic glomerulonephritis and nonglomerular diseases of the kidneys and urinary tract].

Upon the analysis of qualitative and quantitative characteristics of hematuria in renal and urinary tract affections it was established that whatever the red blood cell count in the urine, hematuria is primarily glomerular in contrast to nonglomerular in chronic glomerulonephritis and nonglomerular diseases of the kidneys and urinary tracts, respectively. Morphologic studies of urinary red blood cells using phase-contrast microscopy proved a valuable tool for identification of hematuria origin.

[The beta 2-microglobulin content of the blood serum and urine in patients with primary chronic and lupus glomerulonephritis].

The authors studied the content of beta 2-microglobulin (beta 2-MG) in the blood serum and its excretion with the urine in 85 patients with chronic and 35 with lupoid glomerulonephritis (CGN and LGN) depending on the activity of the disease and state of the renal function. In active CGN and LGN one could observe a distinct increase of the content of beta 2-MG in the blood serum and an increase of its excretion with the urine that may be related to presence of marked dystrophic changes of the canalicular apparatus of the kidneys leading to disorders of reabsorption and beta 2-MG catabolism as well as disorders of the immune homeostasis revealed in these diseases. Results indicate that the beta 2-MG levels in the blood serum and urine may be considered as criteria of CGN and LGN activity.
