Surgical treatment of intradiploic epidermoid cyst treated as depression

Introduction. Extradural intradiploic epidermoid cysts are rare, representing less than 0.25% of all primary intracranial tumors. They can be neurologically silent and can only present psychiatric symptoms like depression, cognitive or personality changes. Case Outline. A 68-year-old male with two year long history of depressive mood, lack of motivation, helplessness, hopelessness and poor response to antidepressive drug therapy was described. CT scan showed a well-defined mass in the parietal scalp with destruction of the scull. He underwent intracranial tumor resection. Surgical resection and cranioplasty were performed. Pathology confirmed intradiploic epidermoid cyst. Conclusion. Total removal of these cysts and repeated washing of the cavity with 0.9 % saline may prevent recurrence and aseptic meningitis and may improve mental state of the patient. We also emphasize the need for neuroimaging studies in a patient with atypical changes in mental status, even without neurological signs or symptoms

Contribution to the study of climate change in Serbia using continentality, oceanity, and aridity indices

The aim of the study is to present some specific climatic conditions on the territory of the Republic of Serbia based on the analysis of four climate indices, which can help in understanding contemporary climate changes. Temperature and precipitation data from 31 meteorological stations for the period 1951–2010 were used. The relative homogeneity of the data series was done using the MASH v3.02 method. The indices used are: Johansson Continentality Index, Kerner Oceanity Index, De Martonne Aridity Index, and Pinna Combinative Index. Geospatial analysis of the distribution of the values of the four mentioned indices was done using the QGIS package 2.8.1. The results of the research show that the continentality effect is present in most of Serbia, while oceanity is observed locally, mainly in the western and southwestern parts of the country. The further analysis showed that there is no dry and semi–dry Mediterranean climate in Serbia. Considering that it is dry in the warmest part of the year (July–September), when the need for water is increased, which is clearly shown by the Walter climate diagram, as well as the fact that an increase in temperature and a decrease in precipitation during the vegetation period were observed in the second 30–year period (1981–2010), it can be concluded that in Serbia there is a tendency towards arid climate. The results presented in this paper can help decision makers to plan certain climate change adaptation measures

Forensic Science and Fractal Nature Analysis

The forensic photography, also referred to as crime scene photography, is an activity that records the initial appearance of the crime scene and physical evidence, in order to provide a permanent record for the court. Now a day, we can imagine the crime scene investigation without photography evidence. Crime or accident scene photographs can often be re-analysed in cold cases or when the images need to be enlarged to show critical details. Fractals are rough or fragmented geometric shape that can be subdivided in parts, each of which is a reduced copy of the whole Fractal dimension (FD) is an important fractal geometry feature. There are many applications in various fields including image processing, image analysis, texture segmentation, shape classification and identifying the image features such as roughness and smoothness of an image. The damage image can be reviewed, analyzed and reconstructed by fractals

Primena hidrostatičkog klipnog uređaja za proveru sile pritezanja i dilatacije zavrtnja pri ostvarivanju zavrtanjske veze

For the most responsible screw connections (especially those with large prestressing) it is very important to precisely define the required tightening force Fp which must not be less than the minimum necessary force Fpmin, nor greater than the maximum permissible force Fpmax . If Fp Fmax plastic deformations may occur and consequently permanent damage of some elements of screw connection.Therefore, the tightening force should be defined as precisely as possible, and then in practice it needs to be adequately measured and controlled in a screw connection. The paper presents an original laboratoryexperimental method for measuring the forces and dilatations of the screw during tightening based on the application of a special hydrostatic piston device as well as a brief description and operating principle of the device. The device was designed at the Higher Technical School of Mechanical Engineering in Trstenik and it can be used for laboratory exercises in technical schools and faculties, as well as in the industry for checking the mechanical properties of the screws before being mounted, and also for various experiments in research laboratories and institutes.Publishe

ONE HUNDRED YEARS OF MILES’ OPERATION- WHAT HAS CHANGED?

Lisfranc was probably the first to excise the rectum for cancer. He performed operation using perineal approach in 1826. This operation came into common use fifty years later. Czerny did the first combined abdominoperineal resection in attempt to finish excision he could not complete from below. Some fifteen years later Ernest Miles described the planned, one stage abdominoperineal resection.Miles name has become a synonym for this combined procedure, creating a radical change in the philosophy of resection and en bloc lymphadenectomy.In the beginning of twenty-century abdominoperineal resection became golden standard in the treatment of rectal cancer. Reconstructive operations, introduction of stapling devices and better understanding of potential tumor spread, reduced indications for Miles operation.Surgical treatment of rectal cancer made progress in the past 100 years. Miles was the first in line. Without his theory of perirectal lymphatic spread recurrence rate would be still as high as 95%

Molekularna detekcija Monilinia fructigena prouzrokovača truleži ploda dunje

Species of the genus Monilinia are important causal agents of fruit rot on pome and stone fruits in Serbia. The pathogen is very harmful, especially on small properties and cottage plantations where intensive control measures are not applied. Quince is important host for the pathogens of this genus. During spring 2010, intensive occurrence of mummified fruits overwintering on branches of the quince was observed. The pathogen was isolated using standard phytopathological methods. Pathogenicity of eight obtained isolates was tested by artificial inoculation of injured apple fruits. Identification was performed according to pathogenic, morphological and ecological properties, and was confirmed by Multiplex polimeraze chain reaction, PCR. All the isolates studied caused brown rot on inoculated apple fruits. The isolates form light yellow colonies with lobate margins, with single-celled, transparent, elliptical or oval conidia in chains, regardless temperature or light presence. Sclerotia are observed in 14 days old cultures. The highest growth rate of most of the isolates is at 27°C and in dark. Based on studied pathogenic, morphological and ecological characteristics, it was found that the Monilinia fructigena is causal agent of brown rot of quince. Using specific primers (MO368-5, MO368-8R, MO368-10R, Laxa-R2) for detection of Monilinia species in Multiplex PCR reaction, the expected fragment 402 bp in size was amplified, which confirmed that the studied isolates belonged to the species M. fructigena.Vrste roda Monilinia su značajni prouzrokovači truleži ploda jabučastog i koštičavog voća u našoj zemlji. Parazit nanosi velike štete, posebno na malim posedima i u vikend zasadima u kojima se ne primenjuje redovna zaštita. Dunja je značajan domaćin patogena ovog roda. Tokom proleća 2010. godine ustanovljena je intenzivnija pojava mumificiranih plodova prezimelih na granama. Cilj ovog rada bio je da se identifikuje prouzrokovač mumifikacije plodova dunje, prikupljenih sa različitih lokaliteta. Patogen je izolovan primenom standardnih fitopatoloških metoda. Patogenost osam dobijenih izolata proverena je veštačkom inokulacijom povređenih plodova jabuke. Identifikacija je obavljena na osnovu patogenih, morfoloških i ekoloških osobina, a potvrđena je primenom Multiplex PCR. Svi proučavani izolati su na inokulisanim plodovima jabuke prouzrokovali trulež smeđe boje. Proučavani izolati na KDA podlozi formiraju svetlo-žute kolonije režnjevitog oboda. U kulturi gljiva, nezavisno od uticaja temperature i prisustva ili odsustva svetlosti, formira jednoćelijske, providne, eliptične ili ovalne konidije u nizovima. Sklerocije se uočavaju u kulturama starosti 14 dana. Većina izolata ostvaruje najbolji porast na temperaturi od 27°C i u odsustvu svetlosti. Na osnovu proučenih patogenih, morfoloških i odgajivačkih odlika, utvrđeno je da izolati pripadaju vrsti Monilinia fructigena. Korišćenjem specifičnih prajmera (MO368-5, MO368-8R, MO368-10R, Laxa-R2) za detekciju vrsta roda Monilinia u Multiplex PCR reakciji, amplifikovan je očekivani fragment veličine oko 402 bp čime je potvrđeno da proučavani izolati pripadaju vrsti M. fructigena
