Level of Information About Radiation Among Medical Staff Working in Operating Rooms With Fluoroscopy

DergiPark: 379005tmsjAims: The aim of this study is to determine the level of information regarding radiation safety and the side effects related to the use of fluoroscopy among a group of teaching assistants, research assistants, medical students, nurses, technicians and caretakers working at Trakya University Health Center for Medical Research and Practice.Methods: A descriptive, cross-sectional survey study was conducted from December 2014 to April 2015 at Trakya University Health Center for Medical Research and Practice. The questionnaire consisted of 24 questions and was applied to 53 people. Responses regarding radiation safety and the side effects of fluoroscopy were analyzed in Statistical Package for the Social Sciences (SPSS) 20.0 using descriptive statistics including frequencies and percentages.Results: 98.08% of the participants responded “yes” to the question ”Do you think fluoroscopy is hazardous to health?”. On the other hand, the results showed that only 32.69% of the participants wore lead apron and 32.77% used thyroid shields in every operation. 88.46% of the participants reported that they would like to attend a training regarding fluoroscopy and radiation safety.Conclusion: The results indicated that the operating room staff of Trakya University Health Center for Medical Research and Practice does not possess adequate knowledge regarding radiation safet

Electrophysiological Correlation and Gradation of Patients Prediagnosed With Carpal Tunnel Syndrome

DergiPark: 378999tmsjAims: In this study, it is aimed to detect electrophysiological correlation of patients who were referred to TrakyaUniversity Medical Research Center Neurology Clinics Electromyography (EMG) lab in 2014 with Carpal Tunnel Syndrome (CTS) pre-diagnosis and grade them based on electrophysiological features.Methods: Electromyography (EMG) records of 174 patients who were sent to electromyography lab in 2014 withCarpal Tunnel Syndrome (CTS) pre diagnosis were scanned retrospectively. Patients were recorded with the data of gender and age. Correlation between pre diagnosis and electrophysiological diagnosis were reported statistically by using Kappa and McNemar tests. Patients were classified based on sex using Chi-square test. Number and percentages, arithmetic mean± standard deviation, median (minimum-maximum) were used as descriptive analysis. Results: Out of all electrophysiological diagnosis, 62 patients (35.6%) were consistent with pre diagnosis when 112(64.4%) were inconsistent. Out of patients who were diagnosed with Carpal Tunnel Syndrome (CTS) according to their electromyography (EMG) findings, 31 patients (48.4%) had mild syndrome.Conclusion: A big inconsistency between pre diagnosis and electromyography (EMG) results was detected. It isimportant to make a more careful and detailed examination to fix this proble

A microdeletion event at 19q13.43 in IDH-mutant astrocytomas is strongly correlated with MYC overexpression

MYC dysregulation is pivotal in the onset and progression of IDH-mutant gliomas, mostly driven by copy-number alterations, regulatory element alterations, or epigenetic changes. Our pilot analysis uncovered instances of relative MYC overexpression without alterations in the proximal MYC network (PMN), prompting a deeper investigation into potential novel oncogenic mechanisms. Analysing comprehensive genomics profiles of 236 “IDH-mutant 1p/19q non-co-deleted” lower-grade gliomas from The Cancer Genome Atlas, we identified somatic genomic alterations within the PMN. In tumours without PMN-alterations but with MYC-overexpression, genes correlated with MYC-overexpression were identified. Our analyses yielded that 86/236 of astrocytomas exhibited no PMN-alterations, a subset of 21/86 displaying relative MYC overexpression. Within this subset, we discovered 42 genes inversely correlated with relative MYC expression, all on 19q. Further analysis pinpointed a minimal common region at 19q13.43, encompassing 15 genes. The inverse correlations of these 15 genes with relative MYC overexpression were re-confirmed using independent scRNAseq data. Further, the micro-deleted astrocytoma subset displayed significantly higher genomic instability compared to WT cases, but lower instability compared to PMN-hit cases. This newly identified 19q micro-deletion represents a potential novel mechanism underlying MYC dysregulation in astrocytomas. Given the prominence of 19q loss in IDH-mutant gliomas, our findings bear significant implications for understanding gliomagenesis

The Parametric Design of a Photovoltaic Power System over a Parking Lot

The effective planning of urban areas is important in terms of improving both the urban density and the traffic problem. Parking lots should be arranged to manage spaces and traffic at the points where the population is highly dense. On the other hand, installing rooftop solar energy plants over parking lots are highly advantageous in terms of renewable energy production. During the design process of such urban power plants, the area-energy optimization and the shading caused by surrounding buildings have direct effect on overall performance. In this study, firstly a parking lot was designed on an empty parcel within the urban area of İzmir province, with the capacity of 1.704 vehicles, 64 motorcycles and 64 electric vehicle charging stations. In addition, a solar power plant was planned over the parking lot canopies, then a power system was designed by selecting the proper photovoltaic panels and inverters. On the parametric simulation software, which was used to determine the system performance, the solar radiation and shadow simulations on the designed parking lot were run. After that, the electricity generation performances were investigated and comparisons between the parking lot parcels and the selected dates were made. In the conclusion, it was found that 7.006 photovoltaic panels placed over the canopies with an area of 24.995 m2 are able to generate 8.084 MWh/year electricity

Atypical lung involvement in a patient with systemic juvenile xanthogranuloma

Juvenile xanthogranuloma (JXG) is a non-Langerhans cell histiocytosis characterized by xanthoma-like cutaneous lesions. It is a benign condition that is generally asymptomatic. Visceral involvement is uncommon, but when present may occur in various locations and in different combinations. Pulmonary involvement has been reported as bilateral, multiple micro- or macronodular lesions. We present a 10-year-old boy with systemic (skin, lung, liver and kidney) JXG who showed lung involvement with mainly an interstitial pattern. Bilateral multiple micronodules in both lungs and mediastinal adenopathy were also present
