Relentless placoid chorioretinitis - A case report

© 2016, Serbia Medical Society. All rights reserved. Introduction Relentless placoid chorioretinitis is an entity which belongs to the group of an atypical intermediate form of primary inflammatory choriocapillaropathies, resembling both acute posterior multifocal placoid pigment epitheliopathy and serpiginous choroiditis, but the retinal distribution and clinical course are not the same. Because of this similarity this entity was termed AMPPiginous. This entity was first described by Jones et al. in 2000. The aim of our case report is to present a very specific case where the clinical course was progressive, with loss of vision in the affected eye. Case Outline A 31-year-old man, with no previous ophthalmic diseases, was hospitalized at the Clinic of Ophthalmology, Clinical Center Kragujevac, because of a reduction of vision in the right eye, and scotoma and metamorphopsia in the left eye. The clinical course of retinal lesions in the left eye resembled the changes observed in acute posterior multifocal placoid pigment epitheliopathy, and the right eye changes were between acute posterior multifocal placoid pigment epitheliopathy and serpiginous choroiditis. The diagnosis of relentless placoid chorioretinitis was confirmed after clinical, laboratory, immunological, virological, and angiography examinations. Conclusion The progressive clinical course of the disease, complemented by multimodal imaging and extensive laboratory diagnostics, has led us to the diagnosis of relentless placoid chorioretinitis. The combined anti-inflammatory and immunomodulatory therapy led to the stabilization of visual acuity of the left eye as opposed to the right, where there has been no recovery

DIRECTIONS IN THE EVOLUTION OF CERVICAL L-SIL LESIONS

Molecular activities in the basic cytopathological substratum of the lesions on utherus cervicus, in case of HPV infection in form of squamous intraepithelial lesions of the low (L - SIL) and high (H - SIL) level, are defined by bathesda therminological system. More frequent, L - SIL changes include CIN I, coil atypia and condilomata lata and can be recognized by cellular abnormalities in the basal and parabasal layer with minor cellular structural changes , nuclei hyperhromasia with hromatin condensation, acantosis, paraceratosis with well differentiated cells and faster exfoliation. Women more prone to develop L-SIL are those older than 41, with III degree of vaginal secretion, with the colposcopic finding of aceto-white epithelium and Papa-Nicholaus test of III group. The control cervical, colposcopically controlled biopsy was resumed after four control medical check-ups done every three months after the L-SIL diagnosis. The results showed that lesions remained at the same stage (41,67%), whereas regression appeared in every third examinee (33,33%), slight progression in every eight examinee (12,50%), and significant progression in every twelfth examinee (8,33%).Our conclusion was that L-SIL lesions do not require the ablativ therapy a priory, and what is needed is a regular colpocytological check-up every three months and cervical biopsy, if necessary. Diagnosis of HPV infection certainly changes one’s attitude and requires loop diameter because of the additional diagnostic indications and final therapy

A STUDY OF THE USE OF MIXED REALITY FOR CAPTURING HUMAN OBSERVATION AND INFERENCES IN PRODUCTION ENVIRONMENTS

Augmented and mixed reality is already considered as needful technology of the modern production systems. It is primarily employed to virtualize proper digital content, mainly related to 3D objects, into the human visual field allowing people to visualize and understand complex spatial shapes, their mutual relations, and positioning. Yet, the huge potential of the technology is waiting to be revealed in its usage for collecting and recording human observations and inferences about the context of the production environment. Its bi-directional interface makes it the most direct and the most efficient knowledge capturing means to date. The paper presents the challenges and benefits that come from the usage of a conceptual interface of an mixed reality application that is designed to collect data, semantics and knowledge about the production context directly from the man-in-process. As a production environment for the development, implementation, and testing of mixed reality applications for this purpose, various processes for the assembly and maintenance of medium-voltage equipment were used

The influence of brake pads thermal conductivity on passanger car brake system efficiency

In phase of vehicle braking system designing, besides of mechanical characteristics, it is also necessary to take under consideration the system's thermal fatures. This is because it is not enough just to achieve proper braking power, for the brake system to be effective but equally important thing is the dissipation of heat to the environment. Heat developed in the friction surfaces dissipate into the environment over the disk in one hand and through the brake linings and caliper, in the other. The striving is to make that greatest amount of heat to dissipate not threw the brake pads butthrew disc. The experimental researching of heat transfer process taking place at vehicle brakes was made in the R&D Center of Zastava automobili car factory in order to increase the efficiency of brake system. The standard laboratory and road test procedures were used, according to factory quality regulations. The modern equipment such as thermo camera, thermo couples, torque transducers, signal amplifiers, optical speed measuring system and laptop computer were used. In this paper will be shown the part of the experimental researching, whichrefers to the thermal conductivity ofbrake pad friction linings

THE ROLE OF CANDIDA ALBICANS ON THE DEVELOPMENT OF STOMATITIS IN PATIENTS WEARING DENTURES

Denture stomatitis is the most common inflammatory reaction that occurs in people who wear dentures. It is believed that in 60-65% of cases the cause of this inflammation is infections by yeasts from the genus Candida (C.), primarily Candida albicans infection. C.albicans is a part of the normal microflora of the respiratory and digestive tract. This yeast has the ability to adhere to the oral mucosa and to the base of the denture, as well as to form a biofilm. Its virulence is especially supported by the state of weakened resistance of the organism, when C.albicans expresses its pathological effect. This paper presents the pathogenesis of C. albicans-associated denture stomatitis, as well as the most common diagnostic and therapeutic procedures used to diagnose and successful therapy

You shall not pass: Mitigating SQL Injection Attacks on Legacy Web Applications

SQL injection (SQLi) attacks pose a significant threat to the security of web applications. Existing approaches do not support object-oriented programming that renders these approaches unable to protect the real-world web apps such as Wordpress, Joomla, or Drupal against SQLi attacks. We propose a novel hybrid static-dynamic analysis for PHP web applications that limits each PHP function for accessing the database. Our tool, SQLBlock, reduces the attack surface of the vulnerable PHP functions in a web application to a set of query descriptors that demonstrate the benign functionality of the PHP function. We implement SQLBlock as a plugin for MySQL and PHP. Our approach does not require any modification to the web app. W evaluate SQLBlock on 11 SQLi vulnerabilities in Wordpress, Joomla, Drupal, Magento, and their plugins. We demonstrate that SQLBlock successfully prevents all 11 SQLi exploits with negligible performance overhead (i.e., a maximum of 3% on a heavily-loaded web server)Comment: Accepted in ASIACCS 202

Nasal morphological characteristics of the serbian population

The aim of this study was to determine the nasal parameters in the population of central Serbia and to compare them with those determined in earlier studies in different populations. The research was conducted on 496 randomly selected persons (262 males and 234 females), aged 18-65 years. The measured parameters were nasal height and nasal breadth and the standard spreading caliper with scale was used for measurements. There were significant differences in the nasal parameters between male and female subjects. The nasal breadth was 34.72 mm in females, and in the male population it was 36.7 mm. The mean values of nasal height were 52.6 mm and 54.32 mm in females and males, respectively. The nasal index in females and males was 66.01 and 67.56, respectively, and the mean value of the nasal index of all respondents was 66.78. After conducting the research it was concluded that the dominant nasal type in the population of the central part of Serbia is leptorrhine. The present study showed the existence of sexual dimorphism in nasal morphology. The data obtained in our study may be useful in anthropological and forensic research, as well as in cosmetic planning and reconstructive surgery

Structural Learning of Attack Vectors for Generating Mutated XSS Attacks

Web applications suffer from cross-site scripting (XSS) attacks that resulting from incomplete or incorrect input sanitization. Learning the structure of attack vectors could enrich the variety of manifestations in generated XSS attacks. In this study, we focus on generating more threatening XSS attacks for the state-of-the-art detection approaches that can find potential XSS vulnerabilities in Web applications, and propose a mechanism for structural learning of attack vectors with the aim of generating mutated XSS attacks in a fully automatic way. Mutated XSS attack generation depends on the analysis of attack vectors and the structural learning mechanism. For the kernel of the learning mechanism, we use a Hidden Markov model (HMM) as the structure of the attack vector model to capture the implicit manner of the attack vector, and this manner is benefited from the syntax meanings that are labeled by the proposed tokenizing mechanism. Bayes theorem is used to determine the number of hidden states in the model for generalizing the structure model. The paper has the contributions as following: (1) automatically learn the structure of attack vectors from practical data analysis to modeling a structure model of attack vectors, (2) mimic the manners and the elements of attack vectors to extend the ability of testing tool for identifying XSS vulnerabilities, (3) be helpful to verify the flaws of blacklist sanitization procedures of Web applications. We evaluated the proposed mechanism by Burp Intruder with a dataset collected from public XSS archives. The results show that mutated XSS attack generation can identify potential vulnerabilities.Comment: In Proceedings TAV-WEB 2010, arXiv:1009.330
