Materials And Methods: The study was carried out using information from medical records of dental patients, information from additional examinations of patients who were treated at the National Medical Research Centre for Dentistry and Maxillofacial Surgery of the Ministry of Health of Russia from 2016 to 2022. Statistical research methods: to evaluate the normality of the distribution, graphical methods were used, as well as the Shapiro-Wilk criterion.

[Surgical treatment of coronary heart disease in elderly patients].

Current approaches to the provision of effective medical aid to elderly patients with cardiovascular diseases are discussed. Clinical characteristics of such patients, concomitant pathologies, the strategy and extent of cardiosurgical treatment and postoperative therapy are described The original observations are compared with literature data concerning the immediate postoperative outcomes, clinical features, and peculiarities ofsurgical intervention in the patients of this age group.

[Plastic surgery of the mitral valve in patients with coronary heart disease].

Modern approaches to cardiosurgical plastic intervention on the mitral valve in case of its ischemic insufficiency are discussed. Etiology of this condition, indications for surgery, and the history of such operations are described. It is concluded that plastic surgery of the mitral valve is the method of choice for the treatment of patients with coronary heart disease.

[Late repeated operations after correction of heart isolated septal defects].

Overall 812 patients with heart isolated septal defects have been operated. Repeated operations were performed at 23 patients. The follow-up ranged 6 months to 15 years.

[Endovascular balloon valvuloplasty of pulmonary artery valvular stenosis].

Summarized experience of balloon valvuloplasty in isolated stenosis of pulmonary artery valve is analyzed. This procedure was performed in Russian Research Center of Surgery in 53 patients from 1980 to 2006. The technique of balloon valvuloplasty is described; short- and long-term results are analyzed.

[Diagnostics of traumatic fat embolism].

The article deals with diagnosis and treatment of fat embolism concomitant with trauma. A new term is suggested, i.e.

[Degree of the severity of fat embolism].

The authors discuss evaluation of the severity of fatty embolism. Three criteria are taken into consideration: clinical symptoms, presence of fat in the serum or liquor, and presence of fat on the surface of serum or liquor. The broth symptom is defined.

[The problem of posttraumatic fat embolism].

The article is devoted to the problem of fat embolism. In 63 patients with combined and isolated traumas the maximum frequency of fat embolism was diagnosed in the investigation of blood serum from the femoral artery. It can be supposed that no isolated injury of the lesser circulation circuit can occur in fat embolism.

[The diagnostic importance of different study methods in the recognition of renovascular hypertension at the prehospital stage].

A comparative study of diagnostic potential of excretory intravenous urography, radionuclide renography and angionephroscintigraphy, renal ultrasonography and ultrasonic dopplerography of renal arteries in prehospital examination for renovascular hypertension made it possible to give preference to the above dopplerography. The latter is able to provide reliable data on renal artery stenosis and genesis of arterial hypertension.

[The comprehensive assessment of the degree of severity of their condition in patients with mechanical jaundice].

The authors examined 42 patients with obstructive jaundice of various severity. Comparison of the findings of radiohepatography with intoxication values according to the medium-weight molecule test and the biochemical parameters revealed statistically significant differences of some quantitative indices depending of the severity of jaundice. The results of the study made it possible to recommend the use of the values of blood clearance, time of maximum accumulation of a radiopharmacological agent in the liver, hepatic and blood retention index, and the medium-weight molecule test for objective quantitative appraisal of the severity of obstructive jaundice.

[Role of imbalance of sex hormones and gonadotropins in the development and course of essential hypertension in women].

Overall 146 females suffering from essential hypertension (borderline, stage I and II according to WHO, 1980) were examined for basal concentrations of estradiol, estriol, progesterone, testosterone, cortisol, ACTH, prolactin in plasma, LH and FSH in blood and urine. The patients and 69 control normotensive females were reproductive, premenopausal, menopausal, postmenopausal, postcastration. Latent hypertension was elicited at bicycle exercise.

[The effect of treatment with human recombinant erythropoietin on the functional status of patients on maintenance hemodialysis].

As many as ten patients with terminal uremia on maintenance hemodialysis (MH) performed from 11 to 52 months (28 +/- 4 on the average) were treated with recombinant human erythropoietin (rhERP) manufactured by Cilag (Switzerland). The preparation was injected i.v.

[Duodenogastric reflux in patients with peptic ulcer].

Complex study of the frequency and intensity of the duodenogastric reflux in 468 patients with peptic ulcer is analysed; 372 had duodenal ulcer and 96 had gastric ulcer. The authors give the characteristics of the diagnostic possibilities of X-ray, endoscopic, ionomanometric, and aspiration (radionuclide and biochemical) methods of examination of duodenal regurgitation. They proved the relation of the frequency and intensity of the duodenal regurgitation to the type of the ulcer and the phase of its course (exacerbation or remission), the condition of the pyloric closure function, and disorders of duodenal motor activity.

[The characteristics of proteinuria during intensive physical loading].

Intensive physical exercise result in certain changes in the body, kidneys in particular. A total of 23 highly qualified sportsmen were investigated for plasma proteins in the urine before and after the graded bicycle ergometry. The impairment of renal reabsorption due to physical load was evidenced by significant amounts of albumin in the afterload urinalyses of all the examinees, and the appearance of IgG in urinalysis of 6 sportsmen in comparison to the urinalysis before the exercise which reported insignificant levels of albumin in 6 subjects only.

[Changes in thrombocyte-vascular hemostasis and cyclic nucleotide levels after anti-arrhythmia therapy in patients with ischemic heart disease].

Platelet-vascular hemostasis and cyclic nucleotide levels as well as the effects of mexitil, ritmilen and prolecofen on those were examined in 58 coronary patients with various heart rhythm disorders. The patients showed considerably increased platelet activity, low prostacyclin level and high thromboxane and cyclic nucleotides levels, particularly in patients with high-grade ventricular extrasystoles. Mexitil did not essentially affect the parameters in question.

[The function of the reticuloendothelial system studied with the use of radioactive colloids].

A new method for the interpretation of data obtained during radionuclide investigation of the reticuloendothelial system (RES) was proposed. It was based on a detailed description of the mechanism of reticuloendothelial extraction of a colloid injected intravenously. A model developed for this purpose included the main stages of radioactive colloid transport.
