This study aimed to investigate human papillomavirus (HPV) type prevalence in our region and the relationship between uterine cervical HPV types and squamous cell carcinoma (SCC)/intraepithelial lesions.

HPV test results were obtained from patient file archives of the Gynecology and Obstetrics Clinic. Pathology report results were obtained from the digital records of the Pathology Laboratory and the patient file archives of the Gynecology and Obstetrics Clinic in 2018.

The most frequently detected was HPV16 (29.2%), followed by HPV51 (13.1%), HPV56 (11%), HPV31 (9.2%), HPV52 (8.4%), and HPV68 (8.2%). HPV16 was positive in 50% of patients diagnosed with SCC, 54.9% of patients with HSIL, 27% of patients with LSIL, and 25% of cases diagnosed as benign (P<0.001). HPV18 was positive in 25% of patients diagnosed with SCC, 11% of patients with HSIL, 4.7% of patients with LSIL, and 5.2% of cases diagnosed as benign (P=0.019).

The most frequent hrHPV genotype was HPV16, followed by HPV51, HPV 56, and HPV 31. There is an increase in the frequency of HPV51 and HPV56. HPV51, not included in HPV vaccines and is the second most frequent, should be included in these vaccines. In addition, although the frequency of HPV18 has decreased, HSIL and SCC generation is still high together with HPV16.

To evaluate the penetration of carbon nanotubes (CNTs) throughout retinoblastoma in a transgenic mice model.

CNTs functionalized with fluorescein isothiocyanate and targeting ligands biotin (CTN-FITC-Bio, 0.5mg/ml), or folic acid (CNT-FITC-FA, 0.5mg/ml) were injected into the vitreous of one eye of LHBETATAG transgenic mice. Other eye did not receive any injection and was used as control. Three mice were sacrificed at days 1, 2, and 3. Eyes were enucleated and stained with 4,6-diamidino-2-phenylindole. The sections were imaged by fluorescent microscope. The images were transformed into grey-scale in MATLAB for intensity analysis. Background intensity was normalized by marking squares outside the eyeball and using the mean intensity of these squares. Fluorescent intensity (FI) for each image was measured by calculating the intensity of a same-sized square within retinoblastoma.

Nine eyes of nine mice were included in each CNT-FITC-Bio and CNT-FITC-FA groups. The mean FI in CNT-FITCBio was 52.08 ± 6.33, 53.62 ± 9.00, and 65.54 ± 5.14 in days 1, 2, and 3, respectively. The mean FI in CNT-FITC-FA was 50.28 ± 7.37, 59.21 ± 6.43, and 58.38 ± 2.32 on days 1, 2, and 3, respectively. FI was significantly higher in eyes injected with CNT-FITC-Bio and CNT-FITC-FA compared to the control eyes (P = 0.02). There was no difference in FI between eyes with CNT-FITC-Bio and CNT-FITC-FA, and FI remained stable on days 1–3 in CNT-FITC-Bio, CNT-FITC-FA, and control eyes (P > 0.05).

We observed higher FI in eyes with CNT-FITC-Bio and CNT-FITC-FA compared to control eyes, showing penetration of CNTs throughout retinoblastoma. CNTs can be a carrier candidate for imaging or therapeutic purposes in retinoblastoma.

Intoxication due to carbon monoxide (CO) is one of the most common types of poisoning. Cardiac effects of carboxyhemoglobin (COHb) range from simple arrhythmias to myocardial infarction..
The current study aimed to investigate the relationship between blood carboxyhemoglobin and high-sensitivity cardiac troponin T (hs-cTnT) level with a highly sensitive assay in patients with acute carbon monoxide poisoning..
Patients and This retrospective study was conducted on 141 (54 males and 87 females) patients, with acute CO intoxication, admitted to the Sevket Yilmaz research and education hospital emergency unit during a one-year period (January 2012 - January 2013). The patients were divided into three groups based on COHb levels: Group I, mild COHb level 25%. COHb, hs-cTnT (Stat), creatine kinase (CK) and creatine kinase-myocardial band (CK-MB) levels were measured on admission..
The mean age of the patients was 38 ± 16 years. COHb levels ranged from 8 to 35. hs-cTnT levels on inclusion in this study were slightly different between the groups (P = 0.05). COHb levels with hs-cTnT values were weakly correlated (r = 0.173, P = 0.041); on the other hand, CK-MB levels were not correlated with COHb (r = 0.013, P = 0.883)..
In patients without clear signs of myocardial infarction, even mild CO poisoning was associated with quantifiable circulating levels of hs-cTnT when TnT was measured using a highly sensitive assay in the current study patients. Plasma levels of the hs-TnT and CK-MB assays were not correlated with the COHb levels in the current study patients..

To compare fear of circumcision, before, immediately after, and ten days after the operation.
This was a case-control study in which participants in the operation group consisted of children admitted for circumcision at the outpatient clinics of a hospital. The Children’s Fear Scale and the Venham Picture Test were administered by face-to-face interviews.
The sample consisted of 100 boys who were circumcised and 99 who have not been circumcised yet. Children’s Fear Scale scores measured before (P = .000) and immediately after the operation (P = .000) were significantly different from scores obtained on the 10th day after the operation. Total fear scores of the Venham Picture Test of boys whose families were in the higher economic level were higher than those of boys from low-income families (P Fear from circumcision does not persist; it considerably vanishes within ten days. It seems reasonable to recommend circumcision for boys six years of age or older. Pre-operative education may help boys to overcome fear originated from circumcision.

To assess the impact of urinary incontinence on the quality of life in Turkish population. This was a cross-sectional study performed on 530 participants admitted to Sevket Yilmaz Research Hospital in Turkey. Quality of life (QoL) was assessed using Incontinence Impact Questionnaire (IIQ-7). Frequency and severity of urinary incontinence (UI) were diagnosed by answers to the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) instrument. The relationship between several demographic data and QoL was examined. The mean age of the attendees was 55.36 ± 10.62 years (range 40-91). A total of 109 (44%) women and 46 (16%) men suffered involuntary urine leakage. QoL changes for all domains showed significant deteriorations. Frequency and severity of UI were negatively associated with the QoL scores. Our results have shown that, UI considerably worsens QoL. Challenge with UI should be priority of any project aiming to promote the quality of life.

To screen the microarray expression of CDH1, ECM1, EIF1B, FXR1, HTR2B, ID2, LMCD1, LTA4H, MTUS1, RAB31, ROBO1, and SATB1 genes which are predictive of primary uveal melanoma metastasis, and NFKB2, PTPN18, MTSS1, GADD45B, SNCG, HHIP, IL12B, CDK4, RPLP0, RPS17, RPS12 genes that are differentially expressed in metastatic uveal melanoma in normal whole human blood and tissues prone to metastatic involvement by uveal melanoma. We screened the GeneNote and GNF BioGPS databases for microarray analysis of genes predictive of primary uveal melanoma metastasis and those differentially expressed in metastatic uveal melanoma in normal whole blood, liver, lung and skin. Microarray analysis showed expression of all 22 genes in normal whole blood, liver, lung and skin, which are the most common sites of metastases. In the GNF BioGPS database, data for expression of the HHIP gene in normal whole blood and skin was not complete. Microarray analysis of genes predicting systemic metastasis of uveal melanoma and genes differentially expressed in metastatic uveal melanoma may not be used as a biomarker for metastasis in whole blood, liver, lung, and skin. Their expression in tissues prone to metastasis may suggest that they play a role in tropism of uveal melanoma metastasis to these tissues.
