Summary:

Objective: to reveal changes of microbloodflow parameters by the laser Doppler flowmetry method in the process of wound defect healing and possibility of their application to modernization of the technologies forwound healing agents effectiveness evaluating. Material and methods. The studies were carried out on 25 white rats divided into 2 groups: 10 control intact rats, 15 animals with a full-thickness experimental skin defect. The microcirculatory parameters of the wound skin edges in rats were evaluated with laser Doppler flowmetry. Histological assay of the wound defect tissues were also performed. Results. It was established that changes in skin microcirculation at the wound defect edges were characterized by inflammatory hyperemia, which was manifested by 27% perfusion increase and increase of normalized amplitudes of myogenic, respiratory and cardiac oscillations. Changes in microcirculation are verified by the morphological picture of inflammation, which reflects an increase in the number of full-blooded vessels of the arterial and venous bed, as well as leukocyte infiltration of the bottom and edges of the wound. Conclusion. Monitoring of microcirculatory disorders occurring in the area of skin wounds allows us to assess the dynamics of the reparative process, which can be used to develop and evaluate the effectiveness of existing drug and non-drug methods of stimulating regeneration.

Summary:

Objective: to reveal the features of anatomical structure of the lower jaw of fetuses of second trimester. Material and methods. The lower jaw of 45 human male and female fetuses of the second trimester has been researched using the method of ultrasound scanning and using the morphological techniques: morphometry and macromicroscopic preparation. Results. The average length of the alveolar arch was 64.1 ±3.6 mm, the average angular width was 30.2±4.0 mm, the average projection length was 24.8±3.5 mm, the average height of branch was 21.1±3.1 mm, the average smallest width of branch was 12.2±1.3 mm. The angle of the lower jaw was equal to an average of 127.2±9.8° with a range of values: from 115 to 156°. According to the long-latitudinal index (LLI) the fetuses had two forms: mesomandibular (39%) and leptomandibular (61%). The shape of the branch of all lower jaws according to the latitude-altitudinal index (LAI) was platyramimandibular. The significant gender differences for the mandibular angle, projection length, angular width (p=0.026; 0.046; 0.039, respectively) were found. The female fetuses were dominated by the angle and projection length, while the male fetuses were dominated by the angular width. Conclusion. Features of the anatomical structure of the lower jaw in the fruits of the second trimester were revealed normally. The data about anatomical structure of the lower jaw of fetuses of second trimester are normally interested for supplement fundamental knowledge about its development in a given age period and has an applied importance forthe detection of congenital malformations, including the use of intravital imaging methods.

Summary:

Objective: to define influence of patient's expectations and physician's role behavior on character and satisfaction with communicative process. Material and methods. The survey of physicians (Л/=232) and patients (Л/=255) was carried out by means of the authorized questionnaires. The questionnaire for doctors was aimed to identify segments of a doctor's professional activity in terms of fulfilling a given social role. The questionnaire for patients made it possible to obtain data on how stable ideas about the "titular" professional qualities of a doctor influence the nature of communication in therapeutic process. Results. It was revealed that the effectiveness of communication process between a physician and a patient was determined by: trust in doctors (88.2%); high stress level of practitioners (69.4%); time allotted for patient's reception (51.7%); level of patient's perception of medical information (42%). The predominantly conflict-free course of the communicative process is noted (62.7%). The most attractive qualities of a physician from patients'viewpoint were described: clarity and completeness of provided information (100%); respectful assessment of personality (62.7%); conflict-free (62.7%); tolerance (74.5%); openness (62.7%); support (62.7%). Conclusion. There were differences in choosing the model of interaction between a physician and a patient. Increase of practitioners' status as a condition and consequence of communication with patients was differentiated by physicians as a need for legal protection of professional activity, a decent pension, an enhance of doctor's professional prestige, and an improvement of working conditions; patients determined it as physicians' adherence to ethical standards in communicating with patients, increase of doctor's professionalism.

Authors: Krivolesova Т.А.
Organization: Saint Petersburg State Pediatric Medical University
Summary:

Objective: by analyzing the results of the activities of medical organizations participating in the compulsory medical insurance system of St. Petersburg, to identify trends in the provision of medical care using in vitro fertilization (IVF) techniques within the framework of the program of state guarantees of free medical care to citizens. Material and methods. The structural component of medical organizations providing medical care using IVF techniques in St. Petersburg over the past 9 years (2013-2021), as well as the volume of medical care provided by them in dynamics over the past 5 years (2016-2020), has been studied. Results. Using the example of St. Petersburg, it was found that the increase in the number of IVF cycles carried out during the implementation of the state guarantee program over the past five years amounted to 42.7%. At the same time, uneven opportunities in carrying out this procedure for residents of different regions are noted. The growth noted in St. Petersburg medical organizations occurred due to the outstripping growth of such services provided to nonresident patients: in 2019, their growth rate compared to the level of 2016 was only 21.3% for residents of St. Petersburg and 129.1% for nonresident patients. The leading role in the growth of indicators is played by medical organizations of non-state forms of ownership, in which 66.3% of all IVF cycles are currently carried out for residents of St. Petersburg and 78.0% for nonresident patients. Conclusion. The significant role of large federal centers identified by the example of St. Petersburg in providing significant amounts of medical care using IVF to nonresident patients should be taken into account when developing regional health development programs in order to prevent restrictions on the availability of medical services for residents of St. Petersburg.

Arnold — Chiari type II malformation (clinical case)

Year: 2022, volume 18 Issue: №2 Pages: 240-244
Heading: Pediatrics Article type: Case report
Authors: Nechaev V.N., Chernenkov Yu.V.
Organization: Saratov State Medical University
Summary:

Using the example of Arnold — Chiari syndrome type II, the difficulties arising in the early diagnosis of this congenital pathology and further tactics of newborn management and surgical correction of the defect are demonstrated. In the presented clinical case, during prenatal ultrasound diagnostics, it was possible to identify a severe malformation of the central nervous system — Chiari malformation — at an early stage. The parents' refusal to terminate the pregnancy and its prolongation ended with delivery by caesarean section. In the postnatal period, the diagnosis of congenital Arnold — Chiari syndrome type II was confirmed, symptomatic treatment was performed and the child was referred for neurosurgical correction, which is the only method to avoid death and severe disability. It should be noted that the forecast for a full and high-quality life remains very dubious due to the high probability of a child's disability.
