Summary:

Purpose: assessment of retinal neuroarchitectonics in presence of optic nerve head (ONH) drusen. Materials and Methods. 108 patients (216 eyes) with bilateral drusen of the optic disc aged 18–60 years were examined, and the control group consisted of 28 healthy subjects. All patients underwent optical coherence tomography (OCT) using Cirrus HD-OCT 5000–7544 device (Carl Zeiss Meditec Inc.). Results. Three types of ONH drusen localization relative to the Bruch membrane were identifed: superfcial, deep and difuse. Difuse localization of the drusen was determined in 48.6 % of cases, deep — in 40.3 %, superfcial — in 11.1 %. Deep optic disc drusen were more common in a young age (35.5±13.1 years), difuse — in medium age (42.0±13.2 years), superfcial — at an older age (51.7±12.8 years). With superfcial and difuse drusen of the optic disc, a signifcant (p<0.05) decrease in the thickness of the ganglion cell (GC) layer in all studied sectors, a decrease in the minimum and average GC thickness was found, as well as a signifcant (p<0.05) decrease in the average thickness and cubic volume of the neuroepithelium. With deep drusen opacities, the changes in GC were less pronounced and statistically insignifcant. Conclusion. analysis of the obtained data showed that deep drusen of the optic disc are the initial stage of congenital pathology, difuse drusen are a developed stage, and superfcial drusen of the optic disc characterize the development of fnal stage.

Migraine and epilepsy: comorbidity and problems in diagnostics

Year: 2019, volume 15 Issue: №1 Pages: 154-158
Heading: Neurology Article type: Review
Authors: Kalinin V.A., Poverennova I.E., Yakunina A.V., Myakinina A.E.
Organization: Samara State Medical University
Summary:

The purpose of this review is to carry out the analysis of published data on comorbidity of migraine and epilepsy. The review is based on results of epidemiological and genetic studies. Clinical manifestations of two diseases are in many respects similar, which sometimes leads to considerable difficulties in diagnostics. Differential diagnosis is based on careful analysis of clinical manifestations, electroencephalography and neuroimaging data. Genetic forms of epilepsy are often accompanied by migrainous headaches. The unity of some pathophysiological mechanisms of epilepsy and migraine predefines comorbidity and directions of diagnostics and treatment for both diseases. Nevertheless, there is a number of questions which demand more precise answers to improve diagnostics and treatment.

The capacity of the thrombin generation test in the diagnostics of hemostasis system disorders in patients with osteoarthritis

Year: 2018, volume 14 Issue: №3 Pages: 602-606
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Shakhmartova S.G., Vorobyova I.S., Puchinyan D.M.
Organization:
Summary:

Aim: to determine the diagnostic significance of thrombin generation test parameters in the diagnostics of hemostatic disorders in patients with osteoarthritis of large joints in preoperative period. Material and Methods. 137 subjects have been investigated, among whom there were 115 hip and knee osteoarthritis patients, submitted for primary arthroplasty (68) and re-prosthetics (47); control group — 22 conventionally healthy blood donors. All subjects underwent plasma hemostasis study and thrombin generation test with two activators — RB (TF 2 pmol/ml) and RC-low (TF 5 pmol/ ml). Osteoarthritis patients were divided into two groups according to the results of thrombin generation test. The 1st group included patients with an adequate response to the stronger activator (t-lagR >t-lag ow, tt-peak^tt-peak^^), the 2nd —with an inversion response (t-lagRBlow). Results. In trie control group and group 1 patients, the thrombin formation process is more pronounced when using an activator with a high TF(RC-low) content than when using an activator with a lowTF (RB) content, which is regarded as an adequate reaction of thrombin formation to the action of a stronger agonist. Patients of the 2nd group inresponse to the action of the activator with a high content of TF was observed inhibition of the reaction of formation of thrombin, which was reflected in the slowdown in the speed of the generation of this enzyme and reduce its quantity. Conclusion. The use of two activators with different concentrations of tissue factor in the test of thrombin generation allows the nature of the response of the hemocoagulation system to initiate the process of thrombin formation to identify patients with adequate and inadequate response.

Organization:
Summary:

Longitudinal flatfoot is heterogeneous group of conditions, characterized by a decrease of longitudinal arch height. In mobile flatfoot, this decrease is dynamic, it occurs under vertical load and proceeds asymptomatically. Specialists should pay attention to the "pathological" flatfoot developing with pain syndrome or causing severe gait disturbance. The review analyzes the fundamental and current opinions of local and foreign researchers on the development of flatfoot in children. Literatural data of age dynamics of foot development, epidemiology of flatfoot in childhood, the influence of flatfoot on the foot and gait biomechanics and basic diagnostic methods are presented.

Heading: Internal Diseases Article type: Case report
Authors: Skryabina E.N., Safonova V.N., Agareva Т.А.
Organization: Saratov State Medical University
Summary:

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare disease that affects small and medium-sized blood vessels of different organs, characterized by asthma, prominent peripheral blood eosinophilia. Cardiac involvement was reported in 20-50% and it is the major cause of mortality. A case of EGPA in a 43-year-old female, who had endocarditis, associated with thrombus formation in left ventricle, thromboembolic syndrome and recurrent stroke has been reported. The described case has showed that it is of crucial importance to perform the full cardiac imaging even in asymptomatic patients with suspected EGPA. The early identification of cardiac involvement may lead to better prognosis.

Resonance radio wave diagnosis of localized sclerodermia: pilot study

Year: 2017, volume 13 Issue: №3 Pages: 585-590
Heading: Dermatovenerology Article type: Original article
Authors: Moiseev A.A., Utz SR.
Organization: Saratov State Medical University
Summary:

The purpose of the research was to study the diagnostic possibilities of the use of the active radiometry method for localized scleroderma (LS), both for monitoring the results of therapy, and for a comprehensive assessment of the functional state of body tissues in the study area, as well as the possibility of determining new foci of the disease. Material and Methods. In a pilot study, patients were presented with different forms of lesions and their different localization, as well as with different disease activity. The method of resonance wave diagnostics is implemented in the diagnostic complex "Aquafon". Results. The primary registration of wave activity in different types of foci may differ. The activity of the foci and the possibility of the appearance of new foci can be said not so much by the data of the initial measurements as by the integral data on their difference before and after the illumination procedure, which requires further study. Conclusion. It is necessary to improve the measurement technique, avoid places where the sensor is not well attached to the skin or minimize this effect. The research also aimed to conduct studies with simultaneous use of other methods.

Summary:

Objective: optimization of the diagnostic algorithm and treatment methods for different clinical forms of the primary hyperparathyroidism. Material and Methods. The article presents the results of examination and operative treatment of 59 patients diagnosed with the primary hyperparathyroidism, such patients having symptoms specific for the disease or having no symptoms of the same. Results. We have not revealed intraoperative complications after surgical interference; laboratory findings have been normalized in 96.6% of cases. The patients having undergone the surgery have been followed up for 12 months with no relapse. 11.9% of the patients have been diagnosed with the asymptomatic primary hyperparathyroidism. Conclusions. Parathyroidectomy is the only radical and effective treatment for the primary hyperparathyroidism. Parathyroidectomy performed surgically to the proper extent, prevents the relapse as well as development of diseases resulting from the primary hyperparathyroidism.
