The occurred death of a convict in prison, police custody cell or in a hospital always attracts public attention and can be considered as a complex phenomenon. The aim of this study is to evaluate the data obtained from autopsies performed to the custody and prison deaths in Istanbul and to discuss the possible solutions by comparing with the literature. It is also aimed to discuss the postponement of the sentence and presidential amnesty facts in Turkey.

Although conventional identification of pathogenic fungi is based on the combination of tests evaluating their morphological and biochemical characteristics, they can fail to identify the less common species or the differentiation of closely related species. In addition these tests are time consuming, labour-intensive and require experienced personnel. We evaluated the feasibility and sufficiency of DNA extraction by Whatman FTA filter matrix technology and DNA sequencing of D1-D2 region of the large ribosomal subunit gene for identification of clinical isolates of 21 yeast and 160 moulds in our clinical mycology laboratory.

Cystic echinococcosis (CE) caused by the metacestode form of Echinococcus granulosus is a major public health problem especially in animal-raising regions of the world. In the present study, CE cases were determined during 2001-2005 by investigating different hospital and health directorship documents and Health Ministry documents, retrospectively. Our results show that there were 2534 (13.

The aims of this study were to determine the methicillin resistance of a total of 256 staphylococcus strains [213 Staphylococcus aureus and 43 coagulase negative staphylococci (CNS)], isolated from different clinical samples and hospital environmental specimens by different methods and to detect multiple antibiotic resistance in these isolates. Methicillin resistance of staphylococci was investigated by using oxacillin agar screening (OAS), oxacillin disk diffusion (ODD), cefoxitin disk diffusion (CDD), PBP2a latex agglutination (LA) and microdilution tests. The resistance of the strains against penicillin G, amoxycillin/clavulanate, cephalothin, tetracycline, erythromycin, fusidic asid, ofloxacin, vancomycin, co-trimoxazole and gentamicin was investigated by standard disk diffusion method.

Article Synopsis
  • Foot intertrigo, often caused by dermatophytes and yeasts, can develop into a complex infection involving multiple organisms due to factors like moisture.
  • A study of 84 patients found bacteria like coagulase-negative staphylococci and Pseudomonas aeruginosa as prominent pathogens, with many patients presenting mixed infections.
  • The research highlights the importance of identifying pathogens and predisposing factors, such as exposure to spa pools, to improve treatment and prevent complications in toe web infections.

Background: Patients with immunodeficiency are prone to infestation with Demodex folliculorum mites. Ultraviolet (UV) radiation can lead to immunosuppression and sebaceous gland hyperplasia. Although some cases of demodicidosis related to UV radiation exposure have been reported, no studies have been performed on the incidence of D.

Objective: Sepsis and ensuing multiorgan failure continue to be the major causes of mortality in intensive care units. Nuclear factor (NF)-kappaB activation is supposed to be one of the targets in the treatment of sepsis. We studied the effectiveness of caffeic phenethyl ester (CAPE), a known NF-kappaB inhibitor, in cecal ligation and puncture (CLP)-induced sepsis and lung injury.

The presence of hepatitis B virus (HBV) DNA in case of negative HBV surface antigen (HBsAg) in serum is known as "occult hepatitis B". There are many reports indicating that occult HBV infections are more frequently encountered in case of hepatocellular carcinoma, hemodialysis practice and co-infections with hepatitis C virus (HCV). The aim of this study was to investigate the presence of HBV-DNA in HBsAg negative hemodialysis.

The detection of genotypes of hepatitis C virus (HCV) which exhibit very high genetic variability, has a great impact for the therapy and follow-up of the chronicity of infections. The aim of this study was to detect the genotypes of HCV strains by using two different methods. Thirty patients (5 hemodialysis patients, 9 chronic hepatitis C patients, 5 blood donors, 1 hospital staff) who were positive for both anti-HCV (Vitros, Ortho-Clinical Diagnostics) and HCV-RNA (Rotorgene, Artus) were included to the study.

Schizophrenia is a serious neuropsychiatric disease of uncertain etiology. We investigated the seropositivity rate for anti-Toxoplasma IgG and IgM antibodies by enzyme-linked immunosorbent assay (ELISA) in patients with schizophrenia to ascertain a possible relationship between Toxoplasma gondii and schizophrenia. We selected 100 patients with schizophrenia, 50 with depressive disorder, and 50 healthy volunteers to investigate the seropositivity rate of anti-Toxoplasma antibodies by ELISA.

Scabies and pediculosis are ubiquitous, contagious, and debilitating parasitic dermatoses. The tendency of high prevalence of pediculosis and scabies among school and preschool age children has prompted us to conduct a head louse and scabies prevalence survey among preschool nursery children in our district. A school-based, crosssectional study was performed, with 1,134 children chosen for evaluation.
