Complexity of serrated sutures of a human skull

Objective: to reveal the variability mechanism of complexity of serrated sutures of a human skull in the correlation with cranial form. Materials and methods. Researches of 253 arches of male and female skulls of patients at the age of 1 day-105 years without signs of cranial trauma or skeletal systemic diseases with absence of morphological signs of increase of intracranial pressure. Minimal (Min) and maximal (Max) values, average arithmetic (M), a mistake of average arithmetic (m) have been studied. For definition of reliability of average size difference parametrical and non-parametric statistical criteria were used: parametrical criterion (t-criterion of Student) applied for parameters submitting to the law of normal distribution (Lakin G. R, 1990). Distinctions of average arithmetic size were considered statistically authentic from 95% (p<0,05) a level of correct judgement (Plokhinskiy N.A., 1970). Results. On the surface of the arch lambdoid and coronal sutures in male skulls and lambdoid and sagittal sutures in female were found out to be of the greatest degree of complexity. Conclusion. The increase of complexity of sutures has been observed in children and adolescents; the directed asymmetry of sutures form is absen

Obliteration of serrated sutures of a human skull (review)

The review presents information on obliteration of serrated sutures of a human skull. It considers the age-specific variability and sexual dimorphism. The causes of craniostenosis and dependence of cranial form on degree and type of craniostenosis are describe

Experience of surgical treatment of unstable СII vertebral fractures

CII arch fractures are divided into groups according not to anatomical localization, but to the instability degree resulted from the trauma. Effendi et al classification became greatly widespread. |t is based on the same stability criteria, but it is simpler, intelligible and gives the plan of treatment. All the fractures according to this classification are divided into three types: the first one consists in stable fractures in which even in functional images there is no any rough deformation at the level of CII segment; the second one consists in damages with significant angular (more than 11°) or shift (more than 3,5 mm) deformations, that indirectly indicates damage of soft tissue structures, and first of all diskoligamentous complex. The services of the authors of the present classification are also that they were the first who had defined fracture-dislocation of CII arch, attributed it to the third type. Choice of surgical procedure in unstable CII-III vertebral fractures is ventral spondylosyndesis of CII-III carried out by submaxillary approach after the preliminary closed elimination of deformation of upper cervical part of spine. The differentiated approach to the implant choice with an allowance for morphometric data allows to receive adequate decompression of nervous - vascular structures and reliable stabilization of the damaged segmen

НЕКРОТИЗИРУЮЩИЙ ЭНТЕРОКОЛИТ У НОВОРОЖДЕННЫХ

The article presents the results of retrospective analysis of treatment of 71 newborns with necrotizing enterocolitis admitted to the Centre of Pediatric Surgery from 2007 to 2015. Peculiarities related to the course of pregnancy, labor, volume and quality of rendered aid at labor, duration of newborns’ stay at the resuscitation departments, treatment type, time of beginning and method of enteral feeding raising, clinical and laboratory data of initial manifestations and signs of necrotizing enterocolitis at the stages of rendering specialized aid before admittance to the hospital. Data are analyzed using https:// medcalc.net/stats/ online program. The most significant factors influencing the outcome of NEC in mature and premature patients considering the body mass at birth and gestational age are established. Groups of risk among pregnant women and premature newborns are revealed. It is established that the most significant factors influencing the outcome of NEC in premature and mature children are represented by the body mass at birth and gestational age.В статье представлены результаты ретроспективного анализа лечения 71 новорожденного с некротизирующим энтероколитом, поступившего в Центр детской хирургии за период с 2007 до 2015 г. Проанализированы особенности течения беременности, родов, объем и качество оказанной помощи при родовспоможении, длительность нахождения новорожденных в отделениях реанимации, характер лечения, время начала и методика наращивания энтерального питания, клинико-лабораторные данные начальных проявлений и манифестации некротизирующего энтероколита на этапах оказания специализированной помощи до поступления в хирургический стационар. Анализ данных проводился с применением компьютерной on-line программы «https://medcalc.net/stats/». Определены наиболее значимые факторы, влияющие на исход НЭК у доношенных и недоношенных пациентов с учетом массы тела при рождении и гестационного возраста, а также выделены группы риска среди беременных женщин и различных категорий недоношенных новорожденных. Установлено, что наиболее значимыми факторами, влияющими на исход некротизирующего энтероколита у доношенных и недоношенных детей являются: масса тела при рождении и гестационный возраст

Stability of Ceramic-Ceramic Restorations for Orthopedic Dentistry

Abstract—This paper presents the results of studying the strength of the joint of denture systems: frame–connecting material–veneer. The developed ceramic based on tetragonal ZrO2 stabilized with ytterbium cation is used as a frame. It is shown that the investigated variants of ceramic-ceramic samples of dentures have high strength of joints. © 2019, Pleiades Publishing, Ltd
