The aim of this study is to conduct several non-invasive methods for assessing the level of circulatory disturbance, elasticity and aging of skin in patients of different age groups in order to expand the diagnostic capabilities and evaluate the effectiveness of current research in aesthetic medicine. Clinical and instrumental exploration of 160 women aged 17 to 75 years with varying degrees of involutional skin changes was carried out. To objectify the assessment of skin condition, in all group of patients modern instrumental methods were used, such as: elastometry, ultrasound examination of the skin, laser Doppler flowmetry, transcutaneous oxygen tension. Concurrent implementation of several non-invasive methods for assessing the level of circulatory disturbance, elasticity and aging of the skin, allowed us to find new possibilities for studying the functional state of the skin. These methods extend the possibilities of ultrasonic research methods used today in aesthetic cosmetology. The obtained comparative data of elastometry, ultrasonography, laser Doppler flowmetry and transcutaneous oximetry in patients of different age groups showed the presence of elasticity and structure defect, skin thickness and subcutaneous fat, as well as microcirculation changes since 25 years and marked changes after 40 years.

© 2018, Media Sfera. All rights reserved. Changes in ocular anatomy and topography that occur due to congenital development anomalies are often of complex, composite nature. Such pathologies are accompanied by not only refractive errors, but also changes in eye’s macrostructure. Careful analysis of the changes is necessary to better understand the clinical picture. Purpose - to study the specifics of structural and morphological changes of the eye in certain ocular congenital pathologies and in some orphan diseases using the results of three-dimensional ultrasound analysis and digital acoustic imaging. Material and methods. The study included 60 patients (119 eyes) with congenital ocular changes, some of which are registered as independent orphan diseases, as well as with systemic manifestations including congenital changes in eye membranes, lens and the vitreous body. The examination involved three-dimensional scanning followed by digital processing of the imaging data obtained using general medical ultrasound systems Voluson 730 Pro Kretz and Voluson E8. Results. Digital ultrasound technologies significantly expand the scope of data on eye morphology in various congenital changes obtainable in vivo. Conclusion. The advantage of this investigation method is the possibility to reliably detect congenital spatially complex morphological deformations in the eye tissues, which in some cases are impossible to observe with other methods.

© 2018, Dynasty Publishing House. All rights reserved. The objective. Was to develop echographic and Doppler prognostic markers of lesions of the central nervous system (CNS) in premature newborns. Patients and methods. In accordance with the objective of the study we conducted a complex prospective examination of 196 pregnant women diagnosed with threatened preterm labour. The treatment group consisted of 166 women, whose pregnancy ended with spontaneous births at terms 22–36 wks, and premature newborns later developed various disorders of CNS. Results. We found morphological ultrasound and Doppler ultrasound specificities of fetal CNS against the background of threatened preterm labour depending on the term of gestation at the moment of birth and subsequent neurological disorders in premature infants. The most significant were changes of the ventriculo-cranial index, width of anterior horns of lateral ventricles, thalamo-occipital distance, systolic-diastolic ratio between vertebrobasilar vessels of the brain. Conclusion. Such a detailed prenatal diagnosis contributes to noninvasive prognostication of the severity of neurological lesions of CNS in premature infants. The results showed interrelations between perinatal outcomes and initial blood flow impairment of fetal CNS in 97% of observations.

PURPOSE: To analyze the condition of the lacrimal gland in patients confirmed to have sarcoidosis. MATERIAL AND METHODS: The study included 46 patients (92 orbits) with verified diagnosis of systemic sarcoidosis that were examined during the period of 2009 to 2014. The age of patients ranged from 23 to 65 years and the average was 45.1 years. Among the examined patients, 66% were female and 34% male. In all patients, the diagnosis was verified according to modern criteria. RESULTS: Acoustic structure of 46 lacrimal glands of patients with systemic sarcoidosis (92 orbit), and lacrimal glands of 30 healthy individuals (60 orbits) were examined. In-depth in vivo examination of morphological changes was done using 'advanced' analysis of three-dimensional images. CONCLUSION: The analysis of a large number of studies devoted to changes in the lacrimal glands caused by sarcoidosis revealed a difficult problem: are there any differences between isolated involvement of the lacrimal gland tissue and the defeat of various organs and tissues? For now, the question remains unanswered.

© 2018 Russian Electronic Journal of Radiology. All rights reserved. Purpose. The purpose of this study was to determine ultrasound criteria of normal temporomandibular joint structure and function. Materials and methods. Prospective study was conducted upon normal 16 TMJs of 9 patients (4 male, 5 female with mean age of 22.9 years) without clinical or radiological signs of disc displacement. All the patients underwent high-resolution ultrasound (Samsung SONO ACE R3, 12 MHz linear probe) and MR imaging of TMJs with the mouth closed and during the maximal mandibular range of motion. Both examinations were performed and interpreted independently by blinded expert operators. Results. Mouth opening range varied from 4.4 cm to 5.4 cm, average amount was defined as 4.94 ± 0.39 cm. Also average heights of the front, middle and rear parts of disc were measured (0,42 ± 0,07 cm; 0,35 ± 0,07 cm and 0,41 ± 0,05 cm, respectively). Structure of the TMJ disc can be defined as fine-grained, hypoechoic and homogeneous. The average height of lower joint space was defined as 0,12 ± 0,03 cm. Average amount of maximal parasagittal mandible condyle movement was defined as 14.7 ± 1.38 mm. Conclusion. Obtained results of ultrasound criteria of normal temporomandibular joint structure and function correspond to the provisions of normal human anatomy and the norm values established for the MRI of the TMJ. Thus, ultrasound criteria of normal temporomandibular joint can be used for assessment of TMJ internal degenerative diseases.

The objective: to study the diagnostic efficiency and to establish normative values of stiffness of ovaries in healthy women of reproductive age, using multiparametric ultrasound (MPUS), advanced with the 2DSWE mode. Patients and methods: In order to establish stiffness of structures of normal ovaries, MPUS with measurement of Jung's modulus in kPa of right and left ovary were held in 25 healthy women of reproductive age between the 5th-7thday of menstrual cycle. For more precise quantitative parameter of Jung's modulus, measurements were repeated at least in two menstrual cycles in every woman. Results: At ovarian MPUS with the 2DSWE technology, determination of stiffness of ovaries in healthy women of reproductive age was carried out at the average volume of ovary 4,9 ± 0,5 cm3(minimum is 3.7 cm3maximum of 6.9 cm3). In addition, in healthy women of reproductive age, quantitative indicators of Jung's modulus of stiffness of structures of ovary (2,5 - 97,5 percentile - 95% interval) were as follows: median Emean is 8.7 kPa (2,1 - 16,9), the SD of 2.6 kPa (0,7 - 4,1). Qualitative analysis of color elastomers obtained showed a uniform homogeneous blue background of intact ovaries in all cases of the study. Conclusion: When extending the algorithm of MPUS with the 2DSWE technology, the effectiveness of the method in the study of normative values of Jung's modulus of stiffness of ovaries in healthy women of reproductive age was 100%.

Цель. Определить у детей в возрасте от 2 до 7 лет ультразвуковых
параметров лимфатических узлов, подверженных наибольшей антигенной
стимуляции (шейные, мезентериальные), и установить взаимосвязь этих
параметров с относительными размерами селезенки. Пациенты и методы.
Проведено открытое скрининговое поперечное одноцентровое исследование на
базе ФНЦ медико-профилактических технологий управления рисками здоровью
населения г. Перми. В исследование включено 133 ребенка (62 мальчика,
71 девочка) из дошкольных учреждений Пермского края в возрасте от 2 до 7
лет. В течение 2011-2013 гг. проведено анкетирование и интервьюирование
родителей респондентов с последующим анализом историй их развития, а
всем детям, включенным в исследование, выполнены стандартная клиническая
гемограмма, а также ультразвуковое исследование (УЗИ) селезенки с
вычислением коэффициента массы селезенки (КМС) по оригинальной формуле и
шейных и мезентериальных лимфатических узлов (ЛУ). В зависимости от
значения КМС дети были поделены на 2 группы: в основной (n = 46) КМС
превышал 4 ед. В группе сравнения (n = 87) этот показатель варьировал от
2,0 до 4,0 ед. Результаты. Дети из основной группы в 2,5 раза чаще (p
< 0,05) болели острыми респираторными вирусными инфекциями, которые
протекали с осложнениями у 27 (58,7%) детей со спленомегалией; в группе
сравнения их было 13 (15,3%, p < 0,01). У детей основной группы в 1,8
раз чаще диагностировали гипертрофию небных миндалин и/или аденоидов
2-3-й степени, они достоверно чаще болели пневмонией. Сравнительный
анализ ультразвуковых характеристик глубоких латеральных яремных ЛУ
показал статистически значимые различия (p < 0,05) по всем измеряемым
параметрам (длина, индекс округлости, толщина коркового слоя), за
исключением максимальной систолической скорости кровотока в артерии
узлов. Характеристики мезентериальных ЛУ (кроме их длины) в обеих
группах пациентов также имели статистически значимые различия.
Обнаружено, что у 43 (93,5%) детей из основной группы преобладали
цепочки или конгломераты (более 2 в ультразвуковом срезе) шейных ЛУ; в
группе сравнения - у 71 (81,6%). Множественные мезентериальные ЛУ
обнаружены в 39 (84,8%) и 64 (73,6%) случаях соответственно в группах.
Корреляционный анализ выявил достоверную (p < 0,05) прямую связь
между значениями КМС и толщиной коркового слоя у глубоких латеральных
яремных ЛУ шеи (r = 0,44). Выводы. У практически здоровых детей
дошкольного возраста с установленной при УЗИ относительной
спленомегалией изменения параметров ЛУ 2-3-го порядка могут отражать
процессы онтогенеза иммунной системы и свидетельствуют о повышенной
антигенной нагрузке. За детьми, значение КМС у которых превышает 4 ед,
рекомендуется динамическое наблюдение с обязательным исследованием
параметров мезентериальных и средних глубоких латеральных яремных ЛУ шеи.
