The question of the relationship between the metric characteristics of cranial structures and odontometric parameters, and the possibility of building models based on them, which can later find their practical application in dental practice, remain a pressing problem of modern medical science. The purpose of the study is to establish the features of the relationship between the linear dimensions of molars with the cephalometric parameters of the brain and facial skull of practically healthy men in the northern region of Ukraine. 32 practically healthy residents of the northern region of Ukraine (from Kyiv, Zhytomyr, Sumy and Chernihiv regions) underwent computed tomography followed by odontometry of molars and cephalometry. The correlations between odontometric and cephalometric parameters were assessed using Spearman’s nonparametric statistics in the licensed package “Statistica 6.1”. The peculiarities of the correlations of the studied characteristics of molars with the indicators of the cerebral skull are established – multiple, only direct reliable (r = 0.35-0.57) and unreliable (r = 0.30-0.35) average correlation force (18.7% on the upper jaw, of which the relative majority with vestibular-lingual and mesio-distal dimensions and 24.1% on the lower jaw, of which the relative majority with the height of the teeth, their crowns and the length of the tooth roots); as well as with the indicators of the facial skull – mostly direct reliable (r = 0.35-0.51) and unreliable medium strength (r = 0.30-0.37) correlations, in most cases of a single nature (6.0% on the upper jaw and 6.6% on the lower jaw, almost uniformly with the height of the teeth, their crowns, root length, vestibular-lingual and mesio-distal dimensions). The results of correlation analysis of craniofacial structures are necessary for the correct construction of mathematical models, which can later find their practical application in dental practice and forensic medicine.

Objective: to report a case of recurrent chronic subdural hematoma treated using endovascular superselective embolization of the middle meningeal artery with the SQUID-18 non-adhesive embolic agent.Materials and methods. A 73-year-old male patient had an open head injury after own height falling. Multislice computed tomography demonstrated chronic subdural hematoma in the left parietooccipital region. The patient had surgery with a positive effect; however, 1 month postoperatively he developed recurrent hematoma. He was diagnosed with recurrent chronic subdural hematoma and underwent endovascular embolization of the distal branches of the middle meningeal artery with a non-adhesive embolic agent; repeated hematoma drainage was not required.Results. Follow-up multislice computed tomography performed 7 months postoperatively demonstrated total resorption of chronic subdural hematoma.Conclusion. This case illustrates the variety of methods that can be used for the treatment of chronic subdural hematoma and shows that endovascular embolization of the middle meningeal artery is a minimally invasive and effective procedure for such a disorder.

Влияние частого и длительного использования электронных устройств (ЭУ) на состояние здоровья молодежи до сих пор недостаточно изучено. Исследования по регламентации использования стационарных и мобильных ЭУ для обеспечения оптимального физического развития молодежи становятся особо актуальными. Целью работы было установить характер и степень влияния использования ЭУ на физическое развитие молодых людей и рекомендовать режим использования ЭУ в течение дня для профилактики возникновения отклонений в физическом развитии. Для определения физического развития 460 старшеклассников и 598 студентов использовали гигиенический, инструментальный, социологический, статистический методы исследования: стандартную антропометрическую методику; для оценки психоэмоционального состояния — тест Спилберга–Ханина; для учета использования ЭУ проводили анкетирование с применением стандартизированных опросников. При среднем суммарном ежедневном времени использования ЭУ у старших школьников, составляющем 7 ч, и у студентов, равном 8,5–10 ч, нормальное физическое развитие выявлено в среднем только у 60% обследованных, причем это не связано с регионом проживания или типом образовательного учреждения. Показано, что частое и длительное использование ЭУ молодежью служит одним из факторов, способных вызвать отклонения в физическом развитии. Установлено, что ежедневное использование стационарных ЭУ увеличивает риск возникновения у подрастающего поколения нарушений в физическом развитии за счет дефицита массы тела на 24% и его избытка на 10%. В качестве профилактических мероприятий рекомендованы отказ от использования стационарных ЭУ, компьютера и ноутбука на 1 день в неделю (в выходной день) и ограничение суммарного времени использования всех видов ЭУ до 3 ч в день.

Liver resection in patients with HCC is the treatment of choice. In patients with insufficient future liver remnant (FLR) and compensated liver function performing the Associated Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) is possible. The classic version of ALPPS consists in ligation of the right branch of the portal vein with transection of the parenchyma and then performing right hepatectomy or right trisegmentectomy. This paper describes the first case in Russia of performing ligation of the left portal branch with transection of the parenchyma and then performing left trisegmentectomy (“reversal” ALPPS) in a patient with HCC and cirrhosis. Reversal ALPPS can be successfully performed in patients with insufficient future liver remnant in well-selected patients.
