[Short-term results of radical surgeries for non-small cell cancer of the lung].

The results of radical surgical treatment of 358 patients with NSCCL were analyzed. Majority of patients were men (84.6%) and persons older 60 years -- 239 (66.8%) patients. Central cancer was diagnosed in 164 (45,8%) patients, peripheral -- in 194 (54.2%). There were 137 (38.3%) pneumonectomies, 184 (51.4%) lobectomies; 149 (41.6%) surgeries were combined. Complications after radical surgeries were seen in 92 (25.7%) of 358 patients, including 18 (5.0%) patients with < > complications and 74 (21%) patients with < > ones. Complications were seen more often in patients over 60 years and occurred less frequently after segmentectomy (7 patients). Lethality was 5.0% (18 patients). Respiratory complications (7 cases) and pulmonary embolism (5 patients) were the main causes of lethal outcome.

[Results of surgical treatment of lung cancer in patients over 70 years old].

Results of surgical treatment of 345 patients (210 men--61%; 135 women--39%) over 70 years with non-small-cell lung cancer were analyzed. Central lung cancer was diagnosed in 141 (40.9%), peripheral--in 204 (59.1%) patients. Squamous cell cancer was seen in 233 (67.3%), glandular--in 67 (19.4%), dimorphic--in 22 (6.5%), large-cell--in 23 (6.8%) patients. Stage I of the disease was diagnosed in 121 (35.1%); stage II--in 49 (14.1%); stage III--in 175 (50.8%) patients. Rate of postoperative complications in the study group was 27.8%, lethality--6.4%. The highest lethality was after combined pneumonectomy. The most frequent postoperative complications were pneumonia (7.5%), arrhythmia (10.1%), pulmonary-heart insufficiency (4.9%). Five-year survival after radical surgery in patients over 70 years with lung cancer was 49%, in patients with stage I of the disease this parameter was the highest--71.4%.

Quasi-probability distributions for the simplest dynamical groups.

We prove that the Wigner-Stratonovich-Agarwal operator that defines the quasi-probability distribution on the sphere [for the SU(2) dynamical group] can be written as an integral of the SU(2) (irreducible unitary) representation element with respect to a single variable that labels the orbits in the coadjoint representation. This allows us to consider contractions of the SU(2) quasi-probability distribution to the cases of the Heisenberg-Weyl group and the two-dimensional Euclidean group.

[Surgical treatment of lung cancer in patients over 80 years of age].

Growth of the specific fraction of individuals over 80 years of age among patients with lung carcinoma is illustrated by its incidence in Moscow. These patients account today for up to 8% of the total number of cases. Some of them may be successfully treated by operation. This was demonstrated in 11 cases. Recommendations on pre- and postoperative management of such patients are given. The authors emphasize that the patient's fate and the method of treatment should be prescribed only in an oncological medical institution.

[Predicting the probable passage of common bile duct calculi in patients with mechanical jaundice].

The authors propose a mathematical method of predictingthe passage of common bile duct calculi. An original mathematical formula derived by a computer allows a 98% accuracy of the prognosis. The estimations were based on the principal parameters influencingthe choledochal calculi movement defined with the help of the regression analysis. Such prediction simplifies the choice of therapeutic policy in mechanical jaundice due to choledocholithiasis.

[Method for angiographic identification of the labyrinth artery].

Digital subtraction angiography in Stenvers standard setting performed atraimatically has been tried in 106 emergency cases admitted to N. V. Sklifosovsky Research Institute of Critical Care. This new method of identification (in 75% of the cases) and verification of the labyrinthine artery intravitally proved safe and reliable. The patients were exposed to cerebral angiography by various methods for diagnosis of the underlying disease. Standard methods of vertebral angiography were found unsatisfactory.

[Radiologic anatomy of the labyrinth artery].

Carotid and vertebral angiographic investigations were performed to study x-ray anatomy of the artery of the labyrinth (AL) in 96 inpatients admitted to the N. F. Sklifosovsky emergency care clinic. According to the angiograms, AL originated from the distal parts of the inferior anterior cerebellar artery in 66.3% of the patients. In this case it has a straight form. When initiating from the proximal parts of the basilar artery (33.7% of the patients), AL was shorter (0.8 +/- 0.3 against 2.5 +/- 0.8 cm) and curved. In any case AL was situated along the upper edge of the pyramid before it entered the internal acoustic meatus. By the meatus or inside it AL forms a characteristic loop or semiloop. A complete AL left-right symmetry was observed in 61.8% of the cases.
