Introduction. The article provides a methodology for assessing and predicting complications during pregnancy for selectionof the optimal method of delivery.Goals and objectives. The work assessed the degree of myometrium changes, according to ultrasound studies, after using standard instrumentation and electrocoagulation, in order to predict the course of pregnancy and select the optimal method of delivery.Materials and methods. The details of the surgical anatomy, the plan of the surgeon’s action before the operation, formed according to the data of ultrasound diagnostics and operative surgery, were analyzed. Ultrasound was performed using GE Logiq S8 (USA) and Medisan Accuvix (South Korea) devices with 3,5 MHz convex transducers for transabdominal examination and with a frequency of 5 MHz for transvaginal examination.Research results. Laparoscopic myomectomy was performed in 18 women, 31 patients underwent laparotomic myomectomy, in 11 patients a combined operation technique was used: laparoscopy with minilaparotomy. According to our data, in half of the cases considered, the effects of interventions were absent or minimal. We assigned these results to group I (A — A1, A2, A3). In all other observations, cicatricial changes were revealed — group II (B, C, D, E). To predict the possible consequences, we proposed a point assessment of the ultrasound postoperative changes in the uterus, with the help of which it is possible to assess the degree of risk when planning pregnancy for each patient individually. Each group corresponds to a certain number of points.Conclusions. The presented division according to the degree of severity into groups can make it possible to individualize the approach to each patient and ensure the safest possible management of her during pregnancy and childbirth. This assessment can be used by ultrasound doctors and obstetricians-gynecologists of antenatal clinics and hospitals. The assessment presented by us at the moment is of a recommendatory nature.

The issues of using data analysis methods to find and correct errors in the reports issued by meteorologists are considered. The features of processing various types of meteorological messages are studied. The advantages and disadvantages of existing methods of classification of text information are considered. The classification methods are compared in order to identify the optimal method that will be used in the developed algorithm for analyzing meteorological messages. The prospects of using each of the methods in the developed algorithm are described. An algorithm for processing the source data is proposed, which consists in using syntactic and logical analysis to preclean the data from various kinds of noise and determine format errors for each type of message. After preliminary preparation the classification method correlates the received set of message characteristics with the previously trained model to determine the error of the current weather report and output the corresponding message to the operator in real time. The software tools used in the algorithm development and implementation processes are described. A complete description of the process of processing a meteorological message is presented from the moment when the message is entered in a text editor until the message is sent to the international weather message exchange service. The developed software is demonstrated, in which the proposed algorithm is implemented, which allows to improve the quality of messages and, as a result, the quality of meteorological forecasts. The results of the implementation of the new algorithm are described by comparing the number of messages containing various types of errors before the implementation of the algorithm and after the implementation.

Colorectal cancer (CRC) is the second leading cause of mortality among cancers after malignant tumors of respiratory system. One of the most significant prognostic features of CRC is tumor budding (TB), which isn’t widely implemented in clinical practice. The aim of this research: to find the prognostic criteria of recurrence and lethal outcome of CRR IIA and IIIB stages (рТ3N0-2M0), the ratio of tumors with certain differentiation in groups of research was taken equal. Material and methods. The group I was formed from primary CRC without recurrences. The main relapse-free survival time was 5 years (62.5 ± 16.5 months). The ІІ group – primary CRC with recurrences; ІІА – with recurrences during 5 years from the moment when the tumor was removed, without fatal outcome; ІІВ – with recurrences and lethal outcome from genera­lization of tumor process during 5 years from the moment when the tumor was removed. The microslides of CRC were made by using the standard methods. Results. TB was identified in 46.66 % (28/60) of CRC рТ3N0-2M0. The direct relationship between tumor grade and presence of TB was found (Р < 0.05), but TB didn’t define differentiation of the CRC. There was a statistically significant relationship between TB and metastatic spreading of CRC to regional lymph nodes (Р < 0.001). Metastasis was associated with 3 stage of TB, absence of metastasis was typical for CRC without TB. The tendency was found in a larger number of cases of the CRC with TB 3 stage among recurring CRC compared with CRC without recurrence, mainly due to the ІІВ group of the research. Inverse correlation between TB stage and time of recurrence appearance was found (Р < 0.05). TB in central tumor sites was followed by presence and higher stage of TB in peripheral tumor sites (Р < 0.05), that can be taken into account during biopsies of CRC. Conclusions. TB is a prognostic criterion of metastasis and time of recurrence appearance for CRC рТ3N0-2M0, which is mostly typical for tumors in patients with recurrences and lethal outcome at the taken equal ratio of tumors by differen­tiation.

Purpose of the study— to study impact of hemi-vertebrae extirpation technique in mono-segmental reconstructionon the surgical trauma.Material and Methods.34 patients underwent 36 mono-segmental extirpations of hemi-vertebrae followed by aposterior fixation during a single center four years cohort study. Mean age of children at the moment of procedure was 4 years and 3 months (min — 1 year, max — 14 years). The authors studied impact of pathology level, surgical approach, type of bony structures removal technique and age of the patients on the time of procedure and volume of blood loss. Results.Extirpation of thoracic hemi-vertebrae was characterized by a lengthier procedure and greater blood lossin contrast to lumbar hemi-vertebrae. Patients were divided into three groups depending on extirpation technique: 1)  extirpation from two approaches using a high-speed burr; 2) from a single dorsal approach using the same extirpation technique; 3) from dorsal approach using ultrasonic bone scalpel. Surgery time was 208±72 min in the first group, 187±54 min in the second group, and 170±30 min in the third group; blood loss volume was 181±39, 181±53, 132±73 ml respectively in the groups, or 11.5±4.3%, 9.4±2.8% and 9.6±5.2% of total blood volume, respectively.Conclusion.Surgical approach and hemi-vertebrae extirpation technique in children have a varying impact onsurgery time and intraoperative blood loss, and the least values were reported for posterior approach using ultrasonic bone scalpel.

Background: Pterygium causes visual problems due to induced corneal astigmatism or direct encroachment onto the visual axis. The present study was conducted to compare preoperative and postoperative changes in corneal astigmatism after pterygium excision by different techniques. Subjects and Methods: The present study was conducted from May 2018 to August 20018 on 69 patients of age range 20-55 years of primary Pterygium. Patients were divided into three groups of 23 each. Group I was treated with bare sclera (BS) technique, Group II with conjunctival autograft (CAG) technique and Group III with amniotic membrane graft (AMG) technique. All the patients were preoperatively assessed for visual acuity, anterior and posterior segments, autorefraction, and autokeratometry. After surgery, the patients were recalled on day 5, 1 month, and 3 months for the analysis. Results: Uncorrected visual acuity (UCVA) preoperatively was 0.57, on the 5th day was 0.45 after 1 month was and after 3 months was 35. The mean preoperative astigmatism value in group I was 3.45, in group II was 3.52 and in group III was 3.49. Postoperative astigmatism value in group I was 1.60, in group II was 0.92 and in group III was 0.81. The difference was significant (P< 0.05). Conclusion: Authors found that amniotic membrane graft and a conjunctival autograft is better surgical techniques than bare sclera in reducing astigmatism.

The first menstruation marks the moment in which a girl enters a completely new period of life and transforms into a woman biologically capable of achieving pregnancy and childbirth. By the time of maturation, puberty, in the girls between the 8th and 13th, it is coming to the so-called axial maturity - hypothalamus-pituitary-ovary. This period is often recognized by intense physical changes, i.e. by the development of the so-called secondary bodily traits - growth, body-shaped changes in girls, breast growth, hair growth on the vulva, and hair growth on axillary pits along with the first menstruation - menarche. The menstrual cycle includes the essence of women’s reproductive life - the ability to achieve pregnancy and childbirth.

Objective: To analyze the factors of the course and outcome of pregnancy in women with pubic joint dysfunction (DLS).Materials and Methods: Th e authors performed a retrospective analysis of the course of pregnancy and the outcome of childbirth in women with pubic joint dysfunction (DLS) observed in 2016 – 2019. As a result, data on the clinical course of pregnancy and childbirth in 75 women with DLS were obtained. All women underwent routine clinical and biochemical examinations, ultrasound diagnostics (US), dopplerometry (DPM), and cardiotocography (CTG). Th e analysis of all the above parameters was carried out according to the data of birth histories for 2016-2018. Statistical processing of the obtained results was carried out using the programs Statistica 10 and Microsoft Excel 2013.Results: Clinical manifestations, as well as changes in ultrasound data, became the main factor in deciding on the method of delivery. All patients with second-degree DLS delivered by elective Caesarean section at 39 – 40 weeks of gestation. Women with the fi rst degree of DLS had a vaginal birth. Ultrasound examination in the postpartum period did not reveal an increase in the diastasis of the pubic joint in any woman. All the postpartum women had no complications during the postpartum period.Conclusion: DLS is a serious complication, which can lead to serious consequences in some cases in the postpartum period. It may require surgical treatment and subsequent long-term rehabilitation. For early diagnostics of DLS, it may be advisable to conduct a mandatory ultrasonic examination of the pubic joint, which is the “gold standard” for the diagnosis of this pathology, to all patients during screening ultrasonic examination.
