Parry Romberg Syndrome

Parry-Romberg syndrome (PRS) is a rare disorder which causes progressive hemifacial atrophy, with ocular manifestations like hypotony, enophthalmos and corneal edema on the ipsilateral atrophic side. This is a report of a unique case of PRS with contalateral manifestations like ectropion uvea, correctopia and endothelial deposits, along with polymegathism and pleomorphism seen on specular microscopy suggestive of Iridocorneal Endothelial (ICE) Syndrome. ICE syndrome and PRS have not been reported together in any literature so far. This case highlights the importance of a thorough glaucoma workup and corneal examination on the atrophic facial side as well as on the apparently normal side in all cases of PRS.

We report a case of a 42-year-old-woman, who presented to the ophthalmic consultation for decreased visual acuity complaints of blurred vision, altered pupillary shape since few months of her right eye. The clinical examination found a reduced visual acuity to counting fingers in the right eye and 20/20 in the left eye. intraocular pressures was 38 mm Hg OD and 14 mm Hg OS. Slit lamp examination of the right eye found: Corneal edema, iris atrophy with a deformation of the iris architecture and pupillary anomalies, with polycoria (Figure 1). The evaluation of the angle by gonioscopy found areas of broad synechiae anterior to Schwalbe’s line (Figure 2). While the examination of the left eye was normal (Figure 1B). The posterior segment examination was normal in both eyes. Specular microscopy confirmed the presence of unilateral endothelial pleomorphism and polymegathism. In our case of the retained diagnosis was iridocorneal endothelial syndrome

Abstract Background To describe a case of a rare association of bilateral keratoconus and unilateral essential iris atrophy and to conduct a literature review of the current strategies of treatment of the corneal disease and glaucoma in patients with Iridocorneal Endothelial Syndrome (ICE). Case presentation We report a rare association of bilateral keratoconus and unilateral essential iris atrophy in a 38-year-old man. Diagnosis of bilateral keratoconus was confirmed by corneal topography. Slit-lamp examination showed extensive iris atrophy with corectopia and policoria in one eye. Corneal specular microscopy revealed an abnormal endothelium morphology in the same eye with extensive peripheral anterior synechiae and closure of the drainage angle at gonioscopy. Intraocular pressure was 26 mmHg, despite maximal topical therapy. Optic disc examination showed severe glaucomatous cupping. Surgery by glaucoma drainage device implantation was performed. Conclusion Essential iris atrophy is a rare clinical variant of ICE syndrome characterized by profound anatomical alterations of the anterior segment associated with corneal edema and secondary glaucoma. In these patients, selective keratoplasties have replaced penetrating keratoplasty to treat corneal decompensation and glaucoma drainage devices are preferred to conventional trabeculectomy for the treatment of secondary glaucoma.

Subject. This article discusses the development of a differentiated strategy of innovative development taking into account the distinguishing features of Russia's regions. Objectives. The article aims to improve the effectiveness of innovative development strategies for Russian regions, which vary in the level of science, technology, and innovation capacities. Methods. For the study, we used statistical, and economic and mathematical methods, normalization principle, the methods of comparative, and expert and sociological analyses, foresight techniques, and original region assessment techniques. Results. The article presents certain criteria for differentiation of Russia's regions, taking into account the level of development of scientific and technical activities, and it proposes three modifications of the regional innovation strategy, corresponding to the main types of Russian regions by scientific and technological development. Conclusions. A differentiated approach to a regional innovation strategy development can improve the efficiency and targeting of government innovation policies by making better use of available resources.

Distinguishing Features

For the first time the morphology of the decapodid stage of Neocrangon communis is described in detail. The decapodid can be distinguished from those of the genera Argis, Crangon, and Mesocrangon by the morphology of their telson, antennae, antennulae, and carapace. The main distinguishing features of the decapodid of N. communis were two spines on medial line of the carapace, a short rostrum, relatively wide scaphocerite, characteristic shape and length of the terminal setae on the telson. Drawings of general view and some limbs are presented.

Relevance. Separate issues in anthropomorphic sizes of relative norm of the ideal smile, its qualitative and qualitative parameters have not been addressed to sufficiently and are not properly reflected in scientific literature.Purpose. To determine distinguishing features in average smile parameters of the smile in male and female patients with orthognathic occlusion.Materials and methods. A clinical and anthropometric evaluation of parameters in main smile types was carried out for 150 young males and 150 young females aged 19-24 who had identical physiological development parameters.Results. It has been revealed that occurrence frequency of main smile types in patients with orthognathic occlusion has pronounced signs of sexual dimorphism which in over one half of the cases lies in predominance of the incisal smile type in males (52.7%) and the fascial type in females (55.3%). Occurence frequency of the cervical smile type totaled 25% among the studied patients of both genders. Average vertical size parameters in the incisal smile lies within the diapason of 3.91-4.91mm with surpassing by 1mm in males. Analogical data for the fascial smile type form the diapason of 6.21-6.73mm with surpassing by 0.52mm in females. The cervical smile type is characterised by larger vertical size forming the diapason of 7.94-8.91mm with surpassing by 0.97mm in males.Conclusion. The results of the study have shown that the “beautiful and ideal smile” is a relative concept having varied anthropometric characteristics and pronounced signs of sexual dimorphism lying in a broad spectrum of the dentofacial system norm notion with specific vectors for individual morphological deviations.

International potential and consequent greater competition in belt wrestling increase the significance of assessing quantitative and qualitative indicators of competitive activity of the strongest wrestlers in the world. It is important to identify the sport development trends and to search for effective ways and tools for achievement of the sport excellence. Purpose: to reveal the features of efficient competitive activities of the world leading wrestlers on the basis of analysis of group differences in technical and tactical excellence indicators. Materials and methods of research. We analyzed videos of 285 events with participation of 197 wrestlers competing at the Belt Wrestling World Championship 2019 in Kazan. We registered the following indicators of competitive activity: the total and average number of fighting techniques, including techniques executed to the right and to the left side within 4 minutes of combat; number and types of technical actions of competition winners among men and women. Research results and discussion. The paper focuses on the comparative analysis of technical and tactical skills of men and women, the winners of the Belt Wrestling World Championship. The research revealed distinguishing features of the winner’s technical toolkit including the diversity of technical and tactical actions, a balance in the knowledge of the right and left-handed techniques. At the same time, the analysis of technical and tactical actions in women wrestling shows the backlog of female athletes in these components of technical fitness.
