The aim of this study was to determine the frequency and distribution of Candida spp. within different age groups and different contraceptive methods users in women with vulvovaginal symptoms. The study included 569 female outpatients who had visited the Education and Research Hospital of Mustafa Kemal University, Turkey, between Jaunary 2004 and June 2005. Among 569 women with symptoms of vulvovaginitis, 240 (42.2%) were positive for Candida spp., of which 106 (44.2%) were C. albicans and 134 (55.8%) were non-albicans spp. The age group 26-30 y had the highest frequency of Candida spp. (23.7%). Candida spp. were isolated from 44.2% of contraceptive method users, and 37.9% of non-contraceptive users (p>0.05). The isolation rate of C. albicans was higher among oral-contraceptive users (57.5%) than IUCD users (38.5%), coitus interruptus (48.5%) and condom users (42.8%). These results indicate that factors associated with age and contraceptive method used may influence the occurrence and distribution of Candida spp. in women with vulvovaginal symptoms.

Background: Onychomycosis has a high prevalance among immunocompromised patients such as diabetics and hemodialysis patients. In the present study, we aimed to investigate the prevalence of onychomycosis among hemodialysis patients with and without diabetes mellitus, and to find out the factors likely to be associated with the development of onychomycosis among hemodialysis patients.Methods: One hundred and nine hemodialysis patients were enrolled. Fifty-seven of hemodialysis patients had the diagnosis of diabetes mellitus. Nail scrapings were obtained from 76 patients who had dystrophic nail changes. Samples were examined with 20% potassium hydroxide solution and all of the samples were inoculated on Saboraud's dextrose agar, potateus dextrose agar and mycobiotic agar. Diagnosis of onychomycosis was based on the presence of both positive clinical signs and positive potassium hydroxide test.Results: Onychomycosis was diagnosed in 26.6% of hemodialysis patients. Diabetes mellitus was present in 68.9% of patients with onychomycosis. Toenail scraping cultures were reported to be positive in 19.7% of patients with dystrophic nail changes. Logistic regression analysis revealed that the presence of diabetes mellitus and the mean duration of hemodialysis were the significant predictors associated with the development of onychomycosis.Conclusion: The prevalence of dystrophic nail changes and onychomycosis is increased among hemodialysis patients. The dialysis duration and the presence of diabetes mellitus are the independent risk factors associated with the development of onychomycosis in uraemic patients.

Introduction: Hepatitis B infection is a serious global public health problem. The aim of the study was to assess the seroprevalance of hepatitis B surface antigen (HBsAg), as well as the risk factors associated with hepatitis B virus (HBV) infection among pregnant women attending antenatal care clinics of the University Hospital in Antioch, Turkey. Methodology: This descriptive cross-sectional study was carried out between May 2016 and December 2016. The Chi-squared was utilized to estimate the statistical significance of the association between socio-demographic variables and HBsAg status. The results were generated as proportions odds ratio (OR) with their 95% confidence intervals (Cl) and calculated by using both univariate and multivariate logistic regression analysis. Results: The seroprevalence of HBsAg was found to be 2.1%. A significant association was observed between age and HBsAg seropositivity (p = 0.027). History of blood transfusion (AOR = 9.51, 95% CI = 1.92-46.80, p = 0.006), history of hepatitis (AOR = 11.13, 95% CI = 2.02-61.28, p = 0.006), tattooing (AOR = 13.64, 95% CI = 2.52-73.76, p = 0.002) and a history of household/close contact (AOR = 11.10, 95% CI = 1.56-78.65, p = 0.016) were significantly associated with the risk of HBV infection. Conclusions: Data regarding the seroprevalence of HBsAg and risk factors associated with HBV infection in pregnant women plays a crucial role in evaluating the effectiveness of the public health protection policies and the strategies to control the disease.

The emergence of new SARS-CoV-2 variants is a challenge to the control of this pandemic. It is therefore important to collect and to analyze data related to the infection caused by different variants. We have obtained more than 3,700 COVID-19 patients between April 2020 and March 2021 from Tokat, Turkey (roughly 3,100 outpatients and close to 600 inpatients) where about 30% were infected with Alpha variant (B.1.1.7). Descriptive statistics was used to characterize different subgroups. Both logistic regression and cause-specific Cox survival analysis of competing-risk was run on inpatients, to examine the impact of Alpha variant on hospitalization, on mortality and on other factors. We observed that the Alpha variant is over-represented in inpatients than outpatients so infection by Alpha variant increases the chance for hospitalization. The impact of Alpha variant on mortality seems to depend on the patient's age. For patients under age of 70, the case-fatality-rate was 0.84% (5.3%) for patients without (with) Alpha variant (Fisher's test P-value = 2.4 × 10⁻¹⁰). For patients above age of 70, the trend is opposite: the case-fatality-rate is 31.5% (13.6%) for patients without (with) Alpha variant (Fisher's test P-value = 0.0016). The two opposite trends would cancel each other, making other analyses such as cause-specific Cox regression and logistic regression non-significant. The Alpha variant increases the risk for hospitalization, increases the case-fatality-rate for lower age group, and decreases the case-fatality-rate for the upper age group. If the increase of case-fatality-rate in not the most senior group holds true, it should provide useful information for a vaccination planning to counter the impact of Alpha variants.

The aim of this study was to compare microbial findings and their resistance to antibiotics between hemodialysis patients and patients without end-stage renal failure with diabetic foot infections. An 18-month-long descriptive study analyzed bacterial isolates obtained from 32 hemodialysis (HD) patients with diabetic foot infection in an Antakya hemodialysis center and 65 patients with diabetic foot infection admitted to the Education and Research Hospital of Mustafa Kemal University, Turkey. No significant difference in the mean number of pathogens per patient was found between the dialysis patients and other patients (2.3 vs. 2.1, respectively) (p > 0.05). While the occurrence of gram-positive bacteria in the HD patients was found to be 59.0%, this rate in the other patients was 53.1% (p > 0.05). While most frequent bacterial species isolated in the HD patients were S. aureus (22.9%), followed by coagulase-negative Staphylococcus spp. (CNS) (19.7%), the microorganisms in the other patients were found as CNS (20.7%), followed S. aureus (18.0%). The data recommend that antibiotic therapy in HD patients with diabetic foot infection should be more closely guided by culture findings and antimicrobial susceptibility results.
