Background: The most common sexually transmitted infection in the world is human papillomavirus (HPV). HPV types 16 and 18 are responsible for 60–80% of cervical cancers and precancerous cervical lesions worldwide. Aim: In this study, it was aimed to evaluate the correlation of HPV genotype distribution with cervical cytology results in cervical smear samples and to contribute to HPV epidemiology. Materials and Methods: This study included 72 female patients. For detection of the HPV genotypes, a multiplex real-time polymerase chain reaction (PCR) method that could detect more than 25 different HPV types was used. The cervical cytology and histopathology results of the patients were also evaluated simultaneously. Results: The frequency of high-risk HPV was 35% (25/72). The most common types were HPV51 (10%), HPV16 (8%), and HPV66 (8%), respectively. The most common type HPV51 and multiple HPV types were seen in 21–34 age groups. HPV DNA was detected in 21 of 43 samples that had cervical smear diagnosis grouping. Twelve samples (26%) had normal cytology. Low grade squamous intraepithelial lesions were the most common cytological diagnosis in HPV DNA positive samples. The most common HPV types in the patients diagnosed low grade squamous intraepithelial lesions and high grade squamous intraepithelial lesions were HPV16 and HPV52. Conclusions: In this study, the frequency of high-risk HPV genotypes was 35% as similar to reports of the other studies conducted in our country. The most common types were HPV51, HPV16, and HPV66, respectively. The follow-up of patients with HPV51 infection in our area could help to improve the natural course of the disease and effective prevention programs.

Introduction: Human bocavirus (HBoV) is a linear single-stranded DNA virus belonging to the Parvoviridae family. This study aimed to investigate the incidence of HBoV and co-infections in pediatric patients with symptoms of viral respiratory tract infection. Methodology: This study included 2,310 patients between the ages of 0-18 in whom HBoV and other respiratory tract viral pathogens were analyzed in nasopharyngeal swab specimens. Results: In the pediatric age group, HBoV was found in 4.5% (105/2310) of the patients and higher in children between the ages of 1 and 5. Mixed infection was detected in 43.8% (46/105) of HBoV positive patients (p = 0.10). Mono and mixed infection rates were higher in outpatients than in inpatients (p < 0.05). Respiratory syncytial virus was significantly higher than the other respiratory viral pathogens (p < 0.001). Conclusions: This study is important as it is one of the rare studies performed on the incidence of HBoV in the Marmara region. In pediatric age group, the incidence of HBoV was found 4.5%. The incidence rate of HBoV in this study was similar to those in studies around the world, but close to low rates. The incidence of HBoV was found higher especially among children between the ages of 1-5 in this study. In addition to the incidence of HBoV, accompanying co-infections in the pediatric age group were also investigated in this study. Since concurrence of RSV, HRV and hMPV with HBoV was the most common it must be considered that there may be more than one agents in patients with symptoms of respiratory tract infection.

Background: Latent Cytomegalovirus (CMV) infections may be reactive in consequence of immunosuppression. Recently, CMV-associated uveitis cases have also been reported in immunocompetent individuals. Aim: The aim of this study was to obtain epidemiological data by evaluating CMV DNA PCR results, clinical characteristics and risk factors of patients diagnosed with viral uveitis. Methods: Between the years 2011-2017, anterior chamber fluid samples of 35 patients with viral uveitis sent from the ophthalmology clinic to the Virology Laboratory were included in this study. CMV DNA real-time PCR results were evaluated. Results: CMV DNA positivity was detected in 9 (26%) of the 35 patients. CMV DNA positivity was highest (13%) in over 60 years (p=0.02). Acute recurrent uveitis in 44% (4/9) of patients, single eye involvement in 78% (7/9) and anterior uveitis in 44% (4/9) were found. Conclusion: In this study, CMV DNA positivity was detected in 26% of the patients with viral uveitis. Considering the presentations of a small number of cases related to CMV uveitis in our country, this study is important due to being the most comprehensive study in our country.

Purpose: The hepatitis C virus (HCV) has seven main genotypes and multiple subtypes. The distribution of HCV genotypes varies across geographical regions worldwide. Updated estimates of HCV genotype distributions have a critical importance for developing strategies to manage or eliminate HCV infection. The aim of this study was to determine the distribution of HCV genotypes in patients with HCV admitted to a university hospital in Istanbul, Turkey. Materials and Methods: A total of 412 HCV RNA positive patients with 46.6% of males and 53.4% of females between January 2013 and September 2016 were included in the study. Genotyping of HCV of the study population was performed by a commercial reverse hybridisation line probe-based assay. Results: Genotype 1 (82.5%) was dominant genotype, followed by genotype 3 (10.7%), genotype 2 (4.6%) and genotype 4 (2.2%). Among patients with genotype 1, subtype 1a, 1b and undetermined subtype were 6.3%, 38.8% and 37.4%, respectively. It was observed that genotype proportion was dependent on gender and age of the patients. Genotype 1 and genotype 2 were more prevalent in females, whereas genotypes 3 and 4 were more prevalent in males. Genotype 1 in the older patients and genotype 3 in the younger patients were more prevalent. Conclusion: The majority of patients with HCV infection had genotype 1 (82.5%), followed by genotype 3, 2 and 4. Monitoring the change in HCV genotype distribution is critical for the development of effective strategies for HCV elimination.

OZ Objective: Several studies have demonstrated that psychiatric patients are at increased risk for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections compared the general population. The aim of this study was to determine the frequency of HBV, HCV and HIV infections among patients with schizophrenia in Elazig Mental Health Hospital in Turkey. Materials and Methods: Screening tests for HBV, HCV and HIV have been routinely performed in patients with schizophrenia. Hepatitis B surface antigen (HBsAg), anti-hepatitis B surface (anti-HBs), anti-HCV and anti-HIV tests were performed by the ELISA technique. Results: Four hundred and eighty-nine patients with schizophrenia in the mental health hospital were screened for HBsAg, anti-HBs, anti-HCV and anti-HIV. The study population was consisted of 409 male and 80 female patients. Overall seroprevalence was detected as 6.5% for HBsAg, 41.5% for anti-HBs and 0.2% for anti-HCV. All patients were found to be anti-HIV-negative. Conclusion: This study showed that the frequency of HBV, HCV and HIV infections among patients with schizophrenia was no higher than in the general population. Screening for blood-borne pathogens at the time of admission to the hospital is an important strategy to identify infected residents. Furthermore, hepatitis

Background: Hepatitis B, hepatitis C and HIV infections constitute serious healthcare problems worldwide. Objectives: There are a limited number of studies regarding the prevalence of hepatitis B, hepatitis C and HIV infections among the drug addicts in Turkey; hence, the current study aimed to determine the frequency of these infections among 235 drug addicts treated in a drug addiction treatment centre/Elazig, Turkey. Patients and Methods: HBsAg, anti-HBs, anti-HCV and anti-HIV tests in 235 drug addicts were studied by ELISA technique. Urine samples obtained from drug addicts were analyzed for cannabis, opiate and cocaine metabolites. Results: All the 235 drug users were males, and their mean age was 30.69 ± 9.494 years; 112 (47.7%) of them were in the age group ranging 20 - 29 years (P < 0.05). Of 235 drug addicts, 113 (48.1%) and 115 (48.9%) were only cannabis and opiate users, respectively. In urine samples of seven (3%) drug addicts both cannabis and opiate metabolites were detected. Cocaine was detected in none of the urine samples. The frequencies of HBsAg, anti-HBs and anti-HCV among drug addicts were 2.6%, 38.3%, and 9.4%, respectively. None of the drug addicts was positive for HIV. Anti-HCV was more prevalent in opiate users than in cannabis users: 15.7% vs. 1.8% (P < 0.001). Conclusions: The obtained results showed that HCV infection was an alarming problem among opiate users in the eastern part of Turkey. It is suggested to rapidly diagnose the infected persons; thus preventive measures and appropriate control may limit further transmission of these infections.
