[Temporary cardiac pacing in patients with acute myocardial infarction in the conditions of air medical service].

Temporary electrical cardiac pacing in the conditions of air medical service was used in 183 patients with myocardial infarction complicated with life threatening disturbances of cardiac rhythm and conduction. Immediate results of treatment, complications, and causes of lethal outcomes are presented. Two groups of patients were distinguished: in which traditional and improved by authors methods of temporary electrical pacing were employed. It was established that the use in urgent situations of improved techniques of control of endocardial electrode position, transesophageal, cutaneous, and atrial dependent endocardial ventricular electrical pacing allowed to decrease number of complications 2.6 times, and to lower mortality in acute period of myocardial infarction by 12.8%.

[Alpha-fetoprotein immunotherapy as a stage of combined treatment of cancer patients].

The paper discusses the preliminary findings on alpha-feto-protein (AFP) treatment of 58 patients with stage III-IV malignancies of different localizations. No influence on neoplastic processes was registered in poorly differentiated cell tumors, nor were any immunological mechanisms of antitumor action triggered on. However, in moderately- and well-differentiated cell tumors, several foci of acute immune inflammation were induced. It is suggested that AFP is responsible for tumor cell apoptosis by freeing antigenic determinants from shielding antibodies via elimination of < > of tumor growth.

[A device for performing drainage into common bile duct].

A new original instrument is proposed for draining the cystic duct into the common bile duct through the stump. The device combines a reliable fixation of the drainage tube in the stump of a narrow (less than 3 mm) or scared altered cystic duct and the not traumatically embedded cannula into the common bile duct.

[Diagnosis, treatment and prophylaxis of postoperative recurrent nodular goiter].

Results of surgical treatment of 81 patients with recurrent goiter and 79 patients with benign nodular forms of goiter are analyzed. Based on clinical data, results of ultrasonic and histological examinations, it was determined that recurrence of goiter does not depend on volume of surgery. It is seen in patients with subclinical forms of postoperative hypothyreosis and in half of cases with lymphoid infiltration of I - IV degree. Dispensary observation and timely prescription of suppressive therapy, if it is necessary, permit to reduce number of goiter recurrences from 8.2 to 2.5%.

[Effect of biological preparation alfetin in infiltrative pulmonary tuberculosis].

The authors evaluated influence of Alfetin new Russian biologic preparation on pulmonary surfactant system and phospholipid metabolism in workers at risk of occupational pneumoconiosis, who suffer from infiltrative pulmonary tuberculosis. Considering positive changes in serum phospholipids subunits under alfetin treatment, the authors proved membrane protective effect of the drug. Alfetin was proved to weaken toxic effects of tuberculostatic drugs on lung surfactant.

[Effectiveness of external drainage of the common bile duct].

Influence of different methods of external drainage of the biliary tract on dynamics of inflammation in the biliary tracts was evaluated based on the data examination of bioimpedance, specific electric conductivity and general microbial number of bile received during surgery and from drainage of the common bile duct during 9 days after surgery in 197 patients with cholelithiasis complicated by bile outflow disturbances. It is demonstrated that each type of external drainage has own indications depending on the degree of bacterial contamination, macroscopic structure, biophysical parameters of bile, and planned treatment policy after surgery. Right fixation of the drainage tube in the common bile duct improves immediate results of surgical treatment of patients with cholelithiasis.

Choledocholithiasis↗

[Biophysical properties of bile and urine in patients with cholelithiasis].

The electric conductivity of the hepatic bile received during and 24 hours after surgery from the drainage introduced into the common hepatic duct was studied in 94 patients with cholelithiasis. It is demonstrated that conductivity increases in cholestasis, inflammatory process in the biliary tract and depends on the hepatic morphofunctional status. The specific electric conductivity of intraoperative bile that is more than 192 S/m is considered to be criteria for the diagnosis of cholangitis. The electric conductivity of urine before and in first 4 days after surgery decreases in inflammation of the biliary tract and depends on the degree of concomitant renal dysfunction and electrolyte disturbances. There was a decrease in the conductivity of bile and urine in all studied groups. Detection of biophysical parameters of biological fluids may objectively control the postoperative period and correct treatment policy.

[Selection of protection regimen of dual-chamber cardiac pacing against paroxysmal supraventricular tachycardia].

Criteria of selection of a type of protection against paroxysmal supraventricular tachycardia were studied in 38 patients with permanent dual-chamber cardiac pacing. Three types of protection were distinguished. Criteria for their selection were presence of "pacemaker syndrome", state of chronotropic function of the heart, frequency of attacks of supraventricular tachycardia, results of modeling of pathological atrial activity. During follow-up after programming of optimal type of protection of dual-chamber pacing (mean duration 5.1 years) chronic supraventricular tachycardia developed in 13.5% of patients, survival was 89.2%.

[The parameters of physico-chemical properties of bile and urine in the diagnosis of pancreatitis associated with cholelithiasis].

Specific electrical conductance (SEC) of the hepatic bile in 94 patients with cholelithiasis and concomitant pancreatitis was increased (p < 0.001) and depended on the degree of cholestasis and the morpho-functional state of the liver. The value of SEC of the intraoperative bile higher than 193 S/m is taken for a criterion of the diagnostics of biliary pancreatitis. The electrical conductance of urine during the first 4 days of observation decreased in patients with acute pancreatitis (p < 0.05), impaired carbohydrate metabolism and concomitant renal dysfunction. The value of SEC of urine lower than 238 S/m corresponds to acute pancreatitis. The investigation of physico-chemical indices of biological liquids in patients with a pathology of the pancreato-biliary system allows to objectively control the course of the disease and to correct the treatment methods.

[Possibilities for ultrasonic diagnosis of pleura pathology in patients with pleural exudate].

The authors have analyzed results of thoracovideoscopy in 45 patients with the syndrome of pleural exudate, 17 of them had undergone the ultrasonic examination of the pleural cavity before thoracoscopy. The examination has revealed high sensibility of the ultrasonic method in the diagnosis of fragmentations of pleural exudate and pathology of the pleural leaves. The endoscopic and echographic classification of the pleural exudate is given depending on the fragmentation degree. The authors consider that echography of the pleural cavity as a noninvasive and highly informative method should be included in the first rank in making an algorithm of clinico-diagnostic measures for patients with exudative pleuritis.

[Pathomorphosis of infiltrative pulmonary tuberculosis: clinical aspects].

Based on the data available in the literature and their own findings, the authors have established that the pathomorphism of infiltrative pulmonary tuberculosis in the preantibiotic age was characterized by negative features, then underwent phases of positive changes and relative stabilization, thereafter it again acquired obviously marked negative peculiarities. At present, the clinical features of new cases of infiltrative pulmonary tuberculosis in Perm residents are the predominance of acute onset (67.3%), disseminated (55.8%) and destructive (91.6%) pattern of specific lesion accompanied by bacterial isolation (84.6%).

[Epidemiological features of the pathomorphism of infiltrative pulmonary tuberculosis in the Perm Region].

The time course of changes in current epidemiological indices and epidemically significant features of the pathomorphism of infiltrative pulmonary tuberculosis in those living in the Perm Region are mainly characterized by negative trends. They lie in the increase or stable maintenance of high rates of morbidity, mortality, and destructive pattern of a lesion accompanied by bacterial isolation. The reason for the established situation is incomplete realization of potentialities of improving actions to detect the disease early, to optimize diagnosis and medical therapy, and to considerably expand an phthisiosurgical aid.

[Lymphotropic immune correction with myelopid in the postoperative period in patients with cancer of the colon and rectum].

An analysis of surgical treatment of 142 patients with cancer of the colon and rectum included 32 emergency cases and 110 scheduled operations. Standard surgical methods only were used in 94 patients, the lymphotropic immunocorrection with myelopidum in the postoperative period was made in 48 patients. The use of lymphotropic immunocorrection was shown to considerably improve the immunological parameters and to decrease postoperative lethality.

[Cerebrospinal fluid fat globules in traumatic fat embolism].

The article is devoted to the problem of diagnosis and treatment of 28 patients with cranio-cerebral injury with posttraumatic fat embolism. In 15 of them fat liquoroglobulia was diagnosed which is a reliable symptom of the cerebral form of fat embolism. The method of detection of fat liquoroglobulia is described. A new method--liquorosorption--was used in treatment of patients with the cerebral form of fat embolism. A disturbance of the hematoencephalic barrier is thought by the authors to be possible in such embolism.
