[Diagnostic criteria of maxillary sinus hypoplasia using cone-beam computed tomography].

Objective: To evaluate the diagnostic significance of X-ray criteria of maxillary sinus hypoplasia.

Material And Methods: Cone-beam computed tomography (CBCT) data of 553 patients (1006 maxillary sinuses) with dental and ENT pathology from Minsk outpatient clinics, were studied. The morphometric parameters of 23 maxillary sinuses with radiological signs of hypoplasia, as well as orbits on the affected side, were analyzed.

Features of the immunological profile of blood and urine in patients with post-infectious glomerulonephritis.

The timely diagnosis and treatment of post-infectious glomerulonephritis (PIGN) is currently limited by the erased and low-symptom nature of the disease, which leads to the search for informative biological markers of the disease, which can be used as immunological indicators of blood and urine. The study was carried out in order to establish the characteristic changes in the immunological parameters of blood and urine in patients with PIGN. The study included 60 patients with PIGN from among the patients, hospitalized in the nephrology department of the Republican Clinical Hospital of Health Care Ministry of the Chuvash Republic in 2015-2018.

Conversion from electrocardiosignals to equivalent electrical sources on heart surface.

Background: The actual task of electrocardiographic examinations is to increase the reliability of diagnosing the condition of the heart. Within the framework of this task, an important direction is the solution of the inverse problem of electrocardiography, based on the processing of electrocardiographic signals of multichannel cardio leads at known electrode coordinates in these leads (Titomir et al. Noninvasiv electrocardiotopography, 2003), (Macfarlane et al.

[Bifid mandibular canal].

The article describes three types of bifurcations of the mandibular canal that were identified as accidental findings in cone-beam computed tomograms of the maxillofacial area of patients subjected to dental treatment. Bifid mandibular canal types are illustraded with clinical cases.

[Quantitative mineralogical analyzes of kidney stones and diagnosing metabolic disorders in female patients with calcium oxalate urolithiasis].

Objective: To conduct a complex examination of female patients with calcium oxalate urolithiasis to detect metabolic disorders, leading to stone formation.

Materials And Methods: The study was carried out using complex physical and chemical methods, including quantitative X-ray phase analysis of urinary stones, pH measurement, volumetry, urine and blood spectrophotometry.

Results: Quantitative mineralogical composition of stones, daily urine pH profile, daily urinary excretion of ions of calcium, magnesium, oxalate, phosphate, citrate and uric acid were determined in 20 female patients with calcium oxalate stones.
