[PMID: 38792316 PMCID: PMC11121896 DOI: 10.3390/jcm13102774] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 04/24/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024] Open
Abstract
Background: The objective of this study was to investigate factors influencing Gallium 68 Prostate Specific Membrane Antigen Positron Emission Tomography (Ga68 PSMA PET-CT) uptake for primary staging in prostate cancer. Methods: Retrospective analysis was conducted on 499 non-metastatic and 243 de novo metastatic prostate cancer cases undergoing Ga68 PSMA PET-CT. Demographic, clinical, and imaging data were collected and analyzed. Multivariate logistic regression determined independent risk factors for metastasis detection on Ga68 PSMA PET-CT. Results: Metastatic cases showed higher levels of total PSA, PSA density (dPSA) and biopsy ISUP grade group compared to non-metastatic cases. Multivariate analysis identified cT2 stage and dPSA as independent predictors of metastasis detection on Ga68 PSMA PET-CT. Conclusions: Ga68 PSMA PET-CT plays a crucial role in prostate cancer staging, with identified factors such as clinical T stage and dPSA significantly impacting its diagnostic accuracy. These findings underscore the importance of Ga68 PSMA PET-CT in refining clinical staging and guiding treatment decisions for prostate cancer patients.

Evaluation of the reliability and readability of ChatGPT-4 responses regarding hypothyroidism during pregnancy. Sci Rep 2024; 14:243. [PMID: 38167988 PMCID: PMC10761760 DOI: 10.1038/s41598-023-50884-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 12/27/2023] [Indexed: 01/05/2024] Open
Abstract
Hypothyroidism is characterized by thyroid hormone deficiency and has adverse effects on both pregnancy and fetal health. Chat Generative Pre-trained Transformer (ChatGPT) is a large language model trained with a very large database from many sources. Our study was aimed to evaluate the reliability and readability of ChatGPT-4 answers about hypothyroidism in pregnancy. A total of 19 questions were created in line with the recommendations in the latest guideline of the American Thyroid Association (ATA) on hypothyroidism in pregnancy and were asked to ChatGPT-4. The reliability and quality of the responses were scored by two independent researchers using the global quality scale (GQS) and modified DISCERN tools. The readability of ChatGPT was assessed used Flesch Reading Ease (FRE) Score, Flesch-Kincaid grade level (FKGL), Gunning Fog Index (GFI), Coleman-Liau Index (CLI), and Simple Measure of Gobbledygook (SMOG) tools. No misleading information was found in any of the answers. The mean mDISCERN score of the responses was 30.26 ± 3.14; the median GQS score was 4 (2-4). In terms of reliability, most of the answers showed moderate (78.9%) followed by good (21.1%) reliability. In the readability analysis, the median FRE was 32.20 (13.00-37.10). The years of education required to read the answers were mostly found at the university level [9 (47.3%)]. Although ChatGPT-4 has significant potential, it can be used as an auxiliary information source for counseling by creating a bridge between patients and clinicians about hypothyroidism in pregnancy. Efforts should be made to improve the reliability and readability of ChatGPT.

Abstract
BACKGROUND The majority of people living with HIV in our country are younger men. However, limited data exist for the sexual health of these patients. Knowledge of the epidemiology in this population may improve health outcomes across the continuum of HIV care. The aim of this study was to determine the prevalence of erectile dysfunction (ED) and its association with some clinical and laboratory factors. METHODS A cross-sectional study was conducted using random sampling in men living with HIV (MLWH) at a tertiary hospital in Turkey. Patients were asked to fill out the five-item International Index of Erectile Function (IIEF-5), and blood was collected for HIV viral load, CD4+ T lymphocyte count, lipids and hormone levels to assess biological aspects at the same clinical visit. RESULTS A total of 107 MLWH were recruited. Mean age was 40.4 ± 12.4 years. ED was found in 73.8% (n = 79) of the participants. Severe ED was found in 6.3%, moderate in 5.1%, mild-moderate 35.4%, mild 53.2% of the participants, respectively. The mean age of men with erectile dysfunction was 42.5 ± 12.5 years, while those without erectile dysfunction were 34.5 ± 10 years (p:0.00). ED was detected more frequently in cases with high Low Density Lipoprotein (LDL) levels (p:0.003). There was no statistically significant difference between ED presence and having hormone abnormality. There was a moderate, negative correlation between age and ED score (r: -0.440, p < 0.001). A negative and low correlation was found between triglyceride level and ED score (r: -0.233, p:0.02). The only predictive variable was age in the multivariate analysis [B: -0.155 (95% CI -0.232 to -0.078), p: <0.001]. CONCLUSIONS Our study revealed a high prevalence of ED in the MLWH cohort. Age was found to be the only factor associated with ED. HIV clinicians should consider routine ED screening with validated measures as a part of the follow-up scheme to improve integrated wellbeing in MLWH.

Abstract
Background Kinesio taping is used to provide rehabilitation after surgical operations. Aim The aim of this study is to determine the effect of kinesio taping (KT) on acute pain, breastfeeding behavior, and comfort level in women with cesarean section. Subjects and Methods This was a randomized, single-blinded study. Women (n = 48) were randomly assigned to KT (n = 24) and control (n = 24) groups. KT was applied to both breasts and rectus abdominis muscles of those in the intervention group at the 8-hour postpartum. VAS (Visual Analogue Scale), LATCH (Breastfeeding Charting System and Documentation Tool), PBSES (Postpartum Breastfeeding Self-Efficacy Scale), and PCS (Postpartum Comfort Scale) were performed on the women in both the intervention and control groups on the 0th, 1st and 2nd postoperative days. Data were analyzed using descriptive statistics, the independent samples t-test, the Chi-square test, and the Friedman test. Results Compared to the control group, the pain level was significantly reduced in the KT group (χ2 = 67,225; P = 0.001), breastfeeding self-efficacy increased (F = 221.940; P = 0.001) and the postpartum comfort level (χ2 = 36.432; P = 0.001) improved. Conclusion In the study, it has been shown that KT has important effects on pain management, breastfeeding success, and increasing comfort level in women with cesarean section compared to the control group and the initial period, and can be used safely.

Abstract
BACKGROUND Empagliflozin is a selective sodium-glucose co-transporter (SGLT2) inhibitor that is approved for the treatment of type 2 diabetes. The beneficial effects of empagliflozin on other organ systems including the heart and kidneys have been proven. The aim of this study is to evaluate the role of empagliflozin on acute lung injury induced by intestinal ischemia-reperfusion (I/R). MATERIALS AND METHODS A total of 27 male Wistar albino rats were divided into three groups: sham, I/R, and I/R + empagliflozin; each group containing nine animals. Sham group rats underwent laparotomy without I/R injury. Rats in the I/R group underwent laparotomy, 1 h of after ischemia-reperfusion injury (superior mesenteric artery ligation was followed by 2 h of reperfusion). Rats in I/R were given empagliflozin (30 mg/kg) by gastric gavage for 7 days before the ischemia-reperfusion injury. All animals were killed at the end of reperfusion and lung tissue samples were obtained for immunohistochemical staining and histopathological investigation in all groups. RESULTS Serum glucose, AST, ALT, creatinine, native thiol, total thiol, and disulfide levels and disulfide-native thiol, disulfide-total thiol, and native thiol-total thiol ratios as well as the IMA levels were analyzed and compared among the groups. While intestinal I/R significantly increases serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatinine levels; did not cause any change in homeostasis parameters and IMA level. Empagliflozin treatment had no significant effect on biochemical parameters. Empagliflozin treatment induced a significant decrease in positive immunostaining for IL-1, IL-6, TNF-alpha, caspase 3, caspase 8, and caspase 9 compared to the I/R group in lung tissue samples. Intestinal I/R caused severe histopathological injury including edema, hemorrhage, increased thickness of the alveolar wall, and infiltration of inflammatory cells into alveolar spaces. Empagliflozin treatment significantly attenuated the severity of intestinal I/R injury. CONCLUSIONS It was concluded that empagliflozin treatment may have beneficial effects in acute lung injury, and, therefore, has the potential for clinical use.

Abstract
Background and aim Antithyroid drugs are first treatment for Graves hyperthyroidism worldwide. Although remission can be achieved in approximately 40-50% of patients in 12-18 months with antithyroid drugs, this period can be extended up to 24 months. We aimed to evaluate the effect of individual clinical/biochemical variables and GREAT score in predicting response to antithyroid drug in Graves disease. Material and methods This is a retrospective single-center study including 99 patients with the first episode of Graves disease treated for at least 18 months. The patients were classified into two groups as those who responded to antithyroid medication at 18-24 months (group 1) and those who did not respond at 24 months and continued with low-dose antithyroid medication (group 2). Results Medical treatment response was obtained in 38 (38.3%) of the patients at 18 months, and in 19 (19.1%) patients at 24 months. Long-term medical treatment (>24 months) was given to the remaining 43 patients due to the lack of response to medical treatment. Thyroid volume and free T4 levels were higher in those followed up with long-term antithyroid drugs, and orbitopathy was more common in this group. Median anti TPO value was significantly higher in group 1 when compared to group 2 (593 U/l and 191.6 U/l respectively). More patients were classified as GREAT class 3 in group 2 when compared to group 1 (46.5% and 12,5% respectively). We analyzed the Thyroperoxidase Antibody(anti TPO) titers, which we divided into three levels, according to groups 1 and 2. Post-hoc Chi-Square analysis revealed that falling into the highest anti TPO category was significantly associated with response to medical therapy in 24 months (p <0.05). Conclusion According to our study, GREAT score and anti TPO Ab titers at presentation may help predict response to ATD in Graves disease.

The relationship of 50 bp deletion in the promoter region of SOD1 gene with viscosity and trace elements in chronic gastritis with Helicobacter Pylori: A case study. J Trace Elem Med Biol 2022; 73:127039. [PMID: 35868167 DOI: 10.1016/j.jtemb.2022.127039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 05/27/2022] [Accepted: 07/14/2022] [Indexed: 11/29/2022]
Abstract
The aim of research was to evaluate the superoxide dismutase-1 (SOD1) promoter region Insertion/Deletion (Ins/Del) gene variations in chronic gastritis patients infected with Helicobacter pylori (H. pylori), as well as the association between trace elements and viscosity. The study consisted 154 volunteer (18-65 age) with 107 H. pylori (+) and 47 (-). Biochemical parameters, whole blood viscosity (WBV), trace element levels and SOD1 promoter region Ins/Del gene variations were analyzed in blood samples provided from patients. It was determined that zinc (Zn), copper (Cu), iron (Fe) and magnesium (Mg) levels decreased whereas WBV, selenium (Se) and Cu/Zn ratio increased in H.pylori (+) chronic gastritis patients. The SOD1 50 bp Ins/Del gene polymorphism genotype and allele frequency distributions in H.pylori (+) and (-) chronic gastritis patients were not statistically significant. It was reported that Zn level decreased in H.pylori (+) patients with a deletion in at least one locus (Ins/Del+Del/Del), Se level increased. It has been found that the presence of H.pylori affects trace element metabolism and biochemical parameters in chronic gastritis patients. The 50 bp Ins/Del polymorphism in the promoter region of the SOD1 gene was shown to have no association with chronic gastritis. Investigation of different variants of the SOD1 gene in patients with gastritis will contribute to the determination of its role in the pathogenesis of the disease.

Abstract
The link between chronic gastritis and chemosensory receptors is considered promising for disease prediction and treatment. The transient receptor potential melastatin member channel 5 (TRPM5) is an ion channel and may be a chemosensor in the gastrointestinal tract. Trace elements and minerals involved in many protein structures can change ion channel activity. Our study aimed to determine trace element and mineral levels according to TRPM5 Asn235Ser missense polymorphism distributions in patients with H. pylori (+) and (-) gastritis and to uncover their possible association with disease pathogenesis. In 109 volunteer patients diagnosed with gastritis [64 H. pylori (+), 45 H. pylori (-)], TRPM5 (Asn235Ser) polymorphism was detected by Kompetitive Allele-Specific PCR method (KASP), but no difference was found between the groups. There are differences between the serum trace element (Se, Zn, Cu, Mg, and Cu/Zn) levels of the two groups. High serum Se and Cu/Zn ratios were detected in H. pylori (+) patients. Cu/Zn ratio can be used as a marker of bacterial inflammation. The amount of Se was found to be statistically significant in the serums of H. pylori (+) patients carrying TT and CT genotype, while the amounts of Zn, Cu, and Mg were found as significant of H. pylori (-) patients. The relationship of Se with the H. pylori needs to be investigated further. In addition, H. pylori (+) patients have a significantly higher neutrophils/lymphocytes ratio (NLR) compared to those with H. pylori (-) NLR can be used as an indicator of inflammation.

Abstract
Background Insulin degludec/aspart (IDegAsp) is a co-formulation with IDeg and IAsp. Different insulin regimens may be switched to IDegAsp. In this study, we aimed to find out the effect of switch to IDegAsp on glycemic control and whether the basal characteristics and treatment modalities of the patients affect the change in glycemic control brought by switch to IDegAsp. Methods We retrospectively analyzed the records of 78 patients whose insulin therapies (basal+bolus, premixed analogues or basal only) were switched on a 1:1 unit basis to IDegAsp±bolus insulin. Oral antidiabetic agents (OADs) given were recorded. At the end of 12th and 24th week, total insulin doses of patients and HbA1c were compared to the baseline. Results There was a statistically significant decrease at HbA1c at 12 weeks (1.4%; p<0.001). There was not a significant difference in HbA1c between the OAD added group and the group with no new OADs(p=0.1). Basal insulin dose was not statistically different from baseline, whereas bolus insulin dose was significantly lower (p=0.007). At the end of 24 weeks the decrease in HbA1c level from baseline was preserved. Conclusion Regardless of the baseline insulin regimen, diabetes type and oral antidiabetic drugs given, HbA1c is significantly lowered after switching to IDegAsp.

Abstract
INTRODUCTION Surgery is one of the treatment alternatives for prostate cancer, and robotic-assisted laparoscopic prostatectomy (RALP) has become the new trend in the past decade. There is no consensus yet for surgeons who will perform RALP whether they need to be trained or experienced in laparoscopy. In this study, it was aimed to investigate the effectiveness of the surgeon's laparoscopy experience in the perioperative and postoperative results of RALP patients. MATERIAL AND METHOD Patients who underwent RALP were retrospectively screened. The first 20 cases done by surgeons in both groups and 40 cases in total were included in the study. Surgeons with laparoscopy training were designated as group 1, and surgeons without laparoscopy training were designated as group 2. Patient's age, preoperative prostate-specific antigen (PSA) value, prostate biopsy pathology, radical prostatectomy pathology, surgical margin positivity, extracapsular extension, and seminal vesicle invasion status, blood transfusion rate, operation time, length of hospital stay, and 1-year follow-up potency and urinary incontinence rates were compared. RESULTS There was no difference between the two groups in terms of age, preoperative PSA, preoperative biopsy results, blood transfusion rates, operation times, and the length of hospital stay of the patients. When the postoperative oncological and functional results of the patients were examined, there was no difference between the two groups in the prostatectomy pathology (p = 0.895), extracapsular extension (pT3a) (p = 0.519), positive surgical margin (pSM) (p = 0.723), and seminal vesicle invasion (pT3b) (p = 0.756). Potency and urinary incontinence rates were similar in both groups at the end of one year follow-up (p = 0.327, 0.500 respectively). CONCLUSIONS Based on our study, it is clearly seen that regardless of the surgeon's experience of laparoscopy, it can be safely preferred when looking at the oncological and functional results of RALP.

Abstract
Background: We compared outcomes of en bloc stapler ligation of the renal hilum with separate Hem-o-lok polymer clip ligation of the renal vessels during laparoscopic nephrectomy (LN). Materials and Methods: Clinical data of patients who underwent LN for renal surgery from January 2009 to December 2015 were collected. Operation time, estimated blood loss, device malfunction rate, open conversion rate, complications and arteriovenous fistula (AVF) formation were evaluated. Results: En bloc stapler ligation and separate clip ligation were performed in 64 and 66 patients, respectively. The mean operative time was 106.8 ± 20.8 min (range: 70–165) in the en bloc stapler ligation group compared with 112.5 ± 24.1 min (range: 70–180) in the separate clip ligation group (P = 0.147). The mean estimated blood loss was 141.4 ± 124.1 ml (range: 25–600) in the en bloc stapler ligation group compared with 147.6 ± 112.4 ml (range: 25–450) in the separate clip ligation group (P = 0.767). The open conversion was required in 7/64 (10.9%) and 2/66 (3.0%) patients in the en bloc stapler ligation and separate clip ligation groups, respectively (P = 0.093). Stapler device malfunction occurred in 6 patients (9.3%). There were no statistically significant differences in overall complications (P = 0.726), minor (Grade 1–2) complications (P = 0.698) and major (Grade 3–5) complications (P = 0.716). No patient was diagnosed with AVF formation during overall median 33-month (interquartile range: 30, range: 24–96) follow-up. Conclusions: En bloc stapler ligation of the renal hilum during nephrectomy is an effective and safe technique. Although there is no reported AVF formation with en bloc stapler ligation of the renal hilum, longer follow-up is necessary.

Abstract
The VGF gene, which has been shown to be metabolically associated with energy balance, glucose homeostasis, insulin secretion process, and biological processes related to overeating, is prominent in relation to obesity. TLQP-21 neuropeptide, derived from the VGF, is considered to promote lipolysis by the beta-adrenergic pathway through targeting the C3aR1 receptor located in the adipocyte membrane. In this study, we aimed to measure the expression levels of the VGF and C3aR1 genes in the adipose tissue of obese subjects and individuals with normal weight determined based on body mass index (BMI), and to reveal the correlation of these levels with obesity. VGF and C3aR1 gene expression levels were measured using Real Time Polymerase Chain Reaction (RT PCR) in the visceral adipose tissue (VAT) samples of 52 obese patients (BMI ≥ 35 kg/m2) and 21 non-obese controls (BMI = 18.5-24.9 kg/m2). The results were statistically analyzed. The VGF expression was lower and the C3aR1 gene expression was higher in obese patients compared to the non-obese control group (p < 0.05). In obese patients, there was a statistically significant positive correlation of 85.6% between VGF and C3aR1, in which when one level increased, the other also increased (p < 0.05, r = 0.856). The findings show that the VGF may be significantly associated with obesity and is very important since it is the first to measure the level of VGF gene expression in human adipose tissue. This research provides new evidence of a link between obesity and VGF/C3aR1 and in the future may help design strategies to combat obesity.

Abstract
Background Breast cancer keeps its importance as an important health problem in developing countries like Turkey. Therefore, breast cancer screening and early diagnosis are more important for these countries. Although there are debates about breast self- examination, it is still involved in breast cancer screening programs in many countries. Aim This study aimed to determine university students' knowledge and practice of Breast Self-Examination (BSE). Materials and Methods The study universe consisted of all the female students studying at a public university. Sample size of 161 was calculated for a predicted event frequency. The research data were collected using a questionnaire. Results A total of 73.3% of the subjects students had heard about BSE. Only half of these students had obtained additional information about BSE. While half of the students indicated that they did perform BSE, 33.3% reported doing so at regular intervals. The majority of the students were aware of BSE and its purpose. Only about half stated, however, that they practice it. Those who practiced BSE were not knowledgeable about how and when to perform it. Conclusions In developing countries, to have adequate knowledge of BSE of young women and to do BSE, it is important to develop a consciousness of breast health and an awareness of breast cancer at this age.

Abstract
PURPOSE To evaluate the characteristics of images generated by magnetic resonance imaging (MRI) and changes in the mass-like lesion (MLL) during the follow-up of patients who underwent partial nephrectomy (PN) with the intra-operative use of hemostatic agents (HAs). METHODS The records of patients who had undergone PN in our clinic due to renal mass between January 2013 and August 2018 were retrospectively reviewed. Our study included 47 patients who were administered one or more HAs during the PN and who received diffusion and dynamic MRI at the post-operative 2nd/4th Queryand 12th month. RESULTS MLL is defined as T2 heterogeneous, intermediate-signal intensity bolster-related mass with a pseudocapsule in the renal parenchymal defect. When we looked at the morphological changes of MLL, the mean largest axial dimensions of masses were 27.3 (range 12.2-44.7) mm in the first follow-up period (2nd/4th months) and 21.2 (range 11-44.7) mm in the 12th month follow-up period. The average change in size of MLL was - 0.66 mm/month. We did not see any significant relationship between observation of MLL in the post-operative follow-up MRI images and the use of HAs such as Surgicel®, Spongostan®, and autologous fatty tissue as well as the amount of the agents used in PN operations (p = 0.405, p = 0.159, respectively). CONCLUSIONS The distinction of MLL causing bolster-related mass and granulomatosis tissue from relapse/recurrence can be made based on the change in mass size observed in the MR images and image characteristics.

Abstract
Aim To investigate the effects of the additional presence of nephrolithiasis on the results of laparoscopic simple nephrectomy in patients with severe hydronephrotic non-functional kidneys. Patients and methods A total of 43 patients in whom severe hydronephrosis had been determined on spiral computerized tomography, who had a renal function of lower than 10% according to the dimercaptosuccinic acid (DMSA) renal scintigraphy, and who had undergone a laparoscopic simple nephrectomy due to persistent renal pain and/or recurrent urinary tract infection and/or unresolved hypertension with multidrug treatment, were included in the study. The patients were divided into two groups based on the presence of renal stone as those with stone formation (Group 1) and those without stone formation (Group 2). The groups were compared with regard to the patients’ demographic characteristics, operation durations, pre- and postoperative hemoglobulin and creatinine levels, percentage of change of postoperative hemoglobulin levels, complications, transfusion requirements, and durations of hospitalization. Results Overall, there were 43 patients including 19 patients in Group 1 and 24 patients in Group 2. Although the durations of operations, the durations of hospitalization, and the rates of change of hemoglobulin were higher in the patients in Group 1, these differences were not statistically significant. Postoperative complications were observed in 21 (48.8%) of the 43 patients. Postoperative complications were observed in 13 patients in Group 1 and in eight patients in Group 2. This difference was determined to be statistically significant (p<0.01). Conclusions We observed that except for the postoperative complication rates, the laparoscopic nephrectomy results in patients with severe hydronephrotic non-functional kidneys with or without stone were similar.

Abstract
Objectives: We aimed to evaluate the effect of American Society of Anesthesiology (ASA) classification scoring and age on complications and surgical outcomes during and after percutaneous nephrolithotomy (PCNL) operation. Material and methods: The records of 263 patients, above the age of 18 years, that underwent PCNL surgery between October 2014 and May 2017 were evaluated retrospectively. The patients were divided into three groups based on their ASA risk scores (ASA 1, 2, 3) and into two groups based on their age (younger and older than 65 years). Postoperative complications were assessed according to the ASA groups and age and according to the Clavien classification system. Results: The number of patients in the ASA 1, 2, and 3 groups were 97 (36.8%), 131 (49.8%) and 35 (13.3%), respectively. Four patients in ASA4 were not included in the study. There was no significant difference in ASA 1, 2, 3 groups in terms of changes in Hgb values, mean duration of operation, and mean hospital stay. When ASA1 was compared to ASA3 and ASA2 was compared to ASA3, there was no significant difference in the incidence of all complication rates. There were 159 (60.4%) patients in the young group and 104 (39.5%) patients in the elderly group. Postoperative PCNL complications of these 2 groups were compared according to Clavien classification system and no significant difference was found in incidence of complications.Conclusions: We believe that PCNL operation can be performed effectively and safely in both ASA3 patients and patients above the age of 65 years.

Abstract
OBJECTIVE To examine the the effect of body mass index (BMI) on PNL results and complications with a large number of patients. MATERIALS AND METHODS A total of 958 patients were included in the study, who underwent percutaneous nephrolithotomy in our clinic between 2008 and 2015. Patients were divided into 2 groups according to their body mass index. Patients with a BMI < 30 kg/m2 were classified as group 1 (n:676) and patients with a BMI ≥ 30 kg/m2 were classified as group 2 (n:282). Achieving stone-free status or having residual stones of ≤ 4 mm were considered as operational success. RESULTS The mean age was 47.9 years for group 1 and 48.9 years for group 2 patients. At postoperative first month CT analysis, residual stone was not observed in 466 patients (69%) of group 1 and 20 (72%) patients of group 2. There was no significant difference between the groups in terms of stone-free status (p=0.348). There was no significant difference between two groups complications. Also, there was no difference between the groups for requiring additional intervention (p=0.924). No other complications were observed in the patients. CONCLUSIONS BMI does not affect the outcomes of percutaneous nephrolithotomy as well as complication rate.

Abstract
Background Prostate cancer is the most common solid tumor. The incidence of prostate cancer shows regional and racial differences. The ideal PSA threshold for prostate biopsy is still being debated. Objective We aimed to investigate cancer detection rates in Turkish men who underwent transrectal ultrasound-guided prostate biopsy (TRUSPB) who had prostate-specific antigen (PSA) levels in the range of 2.5 to 4.0 ng/mL and compare them with the rates of cancer in patients with PSA levels in the range of 4.0 to 10.0 ng/mL. Methods All Turkish men who underwent TRUSPB in our clinic between January 2012 and May 2014 were included; that is, 101 patients (Group 1) with PSA level in the range of 2.5 to 4.0 ng/mL and 522 patients (Group 2) with PSA level in the range of 4.0 to 10.0 ng/mL. Mean PSA level, age, prostate volume, and cancer detection rates were evaluated. Results The mean age was 60.5 and 64 years in Group 1 and Group 2, respectively (P = 0.06). The mean PSA level was determined as 3.1 and 6.8 ng/mL in Group 1 and Group 2, respectively (P = 0.03). The cancer detection rate was 12.7% in Group 1 (n = 13) and 30.8% in Group 2 (n = 161), which revealed a statistically significant difference between the 2 groups (P = 0.001). In Group 1, 9 of 13 patients (69%) had Gleason score of 6, 3 (23%) had Gleason score of 7, and 1 (8%) had a Gleason score of 8. Conclusions The cancer detection rate is lower in Turkish men with PSA level in the range of 2.5 to 4.0 ng/mL when compared with men with PSA level in the range of 4.0 to 10.0 ng/mL. Furthermore, most patients in whom cancer was detected who have a PSA level in the range of 2.5 to 4.0 ng/mL are low risk. Therefore, the benefit of TRUSBP in Turkish men with PSA level between 2.5 and 4 ng/mL is low.

Abstract
OBJECTIVE GON blockade with local anesthetics is an effective treatment for a group of headaches, such as cervicogenic headache, cluster headache, occipital neuralgia, migraine. Our aim was to evaluate the efficacy of greater occipital nerve (GON) blockade in patients with chronic migraine (CM) by using a control group. MATERIALS AND METHODS We included 44 CM patients and randomly divide the patients into two groups, as group A (bupivacaine) and group B (placebo) to our study. GON blockade was administered four times (once per week) with bupivacaine or saline. After 4 weeks of treatment, patients were followed up for 3 months, and findings were recorded once every month for comparing each month's values with the pretreatment values. The primary endpoint was the difference in the frequency of headache (headache days/month). VAS pain scores were also recorded. RESULTS A total of 44 patients had completed the study; no severe adverse effects had occurred. Group A showed a significant decrease in the frequency of headache and VAS scores at the first, second, and third months of follow-up. Similarly, group B showed a significant decrease in the frequency of headache and VAS scores at the first month of follow-up, but second and third months of follow-up showed no significant difference. CONCLUSION Our results suggest that GON blockade with bupivacaine was superior to placebo, has long-lasting effect than placebo, and was found to be effective for the treatment of CM. More studies are needed to better define the safety and cost-effectiveness of GON blockade in CM.

Abstract
Introduction Radical prostatectomy (RP) is considered the best treatment for the management of localized prostate cancer in patients with life expectancy over 10 years. However, a complete recovery is not guaranteed for all patients who received/underwent RP treatment. Biochemical recurrence is frequently observed during the post-operative follow-up period. The main objective in this study is to evaluate the predictive factors of biochemical recurrence in localized prostate cancer patients who underwent RP surgery Material and methods The study included 352 patients with prostate cancer treated by RP at a single institution between February 2004 and June 2014. Detailed pathological and follow-up data of all patients were obtained and analyzed to determine the results. Results Mean follow-up duration was 39.7 months. 83 patients (23%) experienced biochemical recurrence (BCR) during the follow-up period. Mean BCR duration range was 6.56 (1–41) months. In multivariate logistic regression analysis, Gleason score (GS), PSA and extra-capsular tumour spread (ECS) variables were found to be statistically significant as BCR predictive factors. Conclusions According to our study results, it is thought that PSA, GS and ECS can all be used for guidance in choosing a treatment modality for post-RP biochemical recurrence and metastatic disease as predictive factors. However, there is no consensus in this matter and it is still debated.

Abstract
PURPOSE To examine the effect of routine sampling anterior apical cores in the initial prostate biopsy among patients that 14-cores of prostate biopsy (PB) planned. MATERIALS AND METHODS Five-hundred twenty-eight patients with increased prostate-specific antigen (PSA) levels and/or abnormal digital rectal examination underwent transrectal ultrasound and initial PB between November 2012 and October 2013. We performed routine 12-cores extended PB, plus 2 anterior apex samples that were taken from the junction of urethra and apex of the prostate. Site-specific and unique cancer detection rate, tumor characteristics, the presence of clinically insignificant prostate cancer (PCa) (clinical stage ≤ T1, serum PSA level of < 10 ng/mL, biopsy Gleason score ≤ 6, number of positive biopsy cores ≤ 3 and no core with > 50% involvement) and biopsy-related pain were evaluated. RESULTS PCa was detected in 147 of 451 patients (32.6%). The lateral base of the prostate was the most affected area with 128 of 451 patients (28.3%), followed by unique cancer detection, with 17 of 40 patients (43.5%). Anterior apex (n = 6) was in third place after the lateral apex (n = 8). The patients diagnosed by anterior apex cores were all clinically insignificant PCa. The cancer diagnosis rate would be 31% if 12-cores biopsy was used, but the rate was found to be 32.6% in 14-cores biopsy (P = .016). Average biopsy pain, right anterior apex biopsy pain, and left anterior apex biopsy pain were found to register at 0.61, 1.06 and 1.08 points in the visual analog scale pain score, respectively. When right and left anterior apex biopsy pain is compared to average biopsy pain, the pain level was found to be statistically significantly higher in the biopsies of right and left anterior apex (P = .040 and P = .042, respectively). CONCLUSION The gold standard for the diagnosis of PCa is at least 8 cores PB. According to our results, although most PCa diagnosis is carried out with 14-cores PB, it should not be forgotten that these patients might have clinically insignificant PCa.

Abstract
Coronary artery disease (CAD) is a multifactorial disease influenced by genetic and environmental factors. Major risk factors of CAD are hypertension, hyperlipidemia, smoking, family history and obesity. Also polymorphisms in the angiotensin-I converting enzyme (ACE) gene can associate with CAD. The relationship between ACE polymorphisms and other risk factors is not well understood in CAD, likely due to the complex interrelation of genetic and environmental risk factors. The aim of this study was to investigate the associations of CAD risk factors and ACE polymorphisms in patients with CAD. We enrolled 203 consecutive patients and 140 healthy subjects in the study. The severity of CAD was evaluated according to the number of vessels with significant stenosis. ACE insertion (I)/deletion (D) genotype was determined by PCR. The frequency of the DD genotype was significantly higher in patients. D allele frequency was higher among CAD subjects when compared to the control group. The number of stenotic vessels were found to be statistically associated with a high frequency of DD polymorphism and D allele and a low frequency of I allele in patients, especially in male patients. The control group displayed II and ID genotypes more frequently than did the patients. The ACE I/D genotype was associated with hyperlipidemia and smoking history. We consider that the DD polymorphism and D allele may affect the severity of CAD, while I allele may have a protective effect. In conclusion, the ACE I/D genotype may interact with conventional risk criteria in determining the risk of CAD.

Abstract
BACKGROUND We investigate the effects of cigarette smoking on prostate-specific antigen (PSA) using 2 different age groups. METHODS The study was carried out between January 2007 and October 2011 with men; the 2 sets of age groups were: 25 to 35 years and 50 to 70 years old. The participants were divided into 4 groups. Of the 25 to 35 age range, smokers were Group 1, and non-smokers were Group 2; of the 50 to 70 age range, smokers were Group 3 and non-smokers Group 4. In addition, for the 50 to 70 age group, the International Prostate Symptom Score was completed, digital rectal examination was performed, and transabdominal prostate volume was measured. We wanted to see whether prostate-specific antigen (PSA) levels showed a difference between the 2 age groups. RESULTS There were 114 patients in Group 1, 82 in Group 2, 90 in Group 3, and 102 in Group 4. The mean PSA level was 0.7 ± 0.28 ng/mL for Group 1, and 0.6 ± 0.27 ng/mL for Group 2 (p = 0.27), and there was no statistically significant difference between the 2 groups. The mean PSA was 2.5 ± 1.8 ng/mL for Group 3, and 2.1 ± 2.0 ng/mL (p = 0.59) for Group 4, and there was no statistically significant difference between the these 2 age groups. INTERPRETATION Cigarette smoking effects various hormone levels. Different from previous studies, the PSA level was higher in smokers compared to nonsmokers, although it was not statistically significant. Our study is limited by the small numbers in our study groups and the lack of PSA velocity data.

Abstract
Introduction: We assessed the effect of different voiding positionson uroflowmetric parameters and post-void residual (PVR)urine volume in symptomatic benign prostatic hyperplasia (BPH)patients. We also evaluated the effect of alpha blockers on PVR indifferent voiding positions.Methods: The study was performed with 110 BPH patients over 50years old. In total, 4 uroflowmetries were performed in all patients:2 patients in the sitting position and 2 in the standing position. PVRwas measured with transabdominal ultrasonography. Also, patientswere divided into two groups according to the alpha adrenergicblocker treatment; the effect of this treatment on their uroflowmetricparameters in different positions was evaluated.Results: Maximum flow rate (Qmax) and average flow rate (Qave)were significantly higher in patients in the sitting position, butthere were no differences in other uroflowmetric parameters andPVR volume (Qmax: 15.5±5.9 mL/s vs. 13.7±5.2 mL/s, Qave:11.4±4.6 mL/s vs. 10.7± 3.9 mL/s, respectively; p < 0.05). TheQmax and Qave were significantly higher in sitting position, comparedto the standing position, in both alpha adrenergic treatmentand non-treated groups; again, there were no differences in otheruroflowmetric parameters and PVR volume.Conclusion: Qmax and Qave values were significantly higher inthe sitting position. Alpha blockers did not affect any change.

Abstract
Infertility affects about 10-15% of all couples attempting pregnancy with infertility attributed to the male partner in approximately half of the cases. Proposed causes of male infertility include sperm motility disturbances, Y chromosome microdeletions, chromosomal abnormalities, single gene mutations, and sperm mitochondrial DNA (mtDNA) rearrangements. To investigate the etiology of decreased sperm fertility and motility of sperm and to develop an appropriate therapeutic strategy, the molecular basis of these defects must be elucidated. In this study, we aimed to reveal the relationships between the genetic factors including sperm mtDNA mutations, Y chromosome microdeletions, and sperm parameters that can be regarded as candidate factors for male infertility. Thirty men with a history of infertility and 30 fertile men were recruited to the study. Y chromosome microdeletions were analyzed by multiplex PCR. Mitochondrial genes ATPase6, Cytb, and ND1, were amplified by PCR and then analyzed by direct sequencing. No Y chromosome microdeletions were detected in either group. However, a total of 38 different nucleotide substitutions were identified in the examined mitochondrial genes in both groups, all of which are statistically non-significant. Fifteen substitutions caused an amino acid change and 12 were considered novel mutations. As a conclusion, mtDNA mutations and Y chromosome microdeletions in male infertility should be examined in larger numbers in order to clarify the effect of genetic factors.

Abstract
INTRODUCTION Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults, responsible for approximately 90% of all kidney cancers. Prior to 2005, treatment options for patients with locally advanced and metastatic disease were limited. After the approval of sorafenib by the US Food and Drug Administration (FDA), other tyrosine kinase inhibitors (TKI) have been successively used for treating patients with advanced RCC. Pazopanib is the newest, orally bioavailable, and multi-targeted TKI, and is considered a first-line treatment option for certain patients. This review summarizes updated clinical studies, mechanism of action, and pharmacokinetics of pazopanib. MATERIALS AND METHODS Published English language literatures and data information on pazopanib for treating advanced RCC available as of March 2011 were identified and summarized. RESULTS In phase II and III randomized clinical trials, pazopanib treatment resulted in considerably longer progression-free survival in patients with advanced RCC compared to placebo, with an acceptable side-effect profile. In addition, there are a few ongoing pazopanib studies including comparison to other TKIs, use for patients who have failed prior cytokine therapy, and combination with other therapeutic agents. CONCLUSIONS Pazopanib has been used in the United States, Europe and Canada for treating patients with advanced RCC. Currently, it is being used in good or intermediate risk RCC and shows survival benefit with acceptable adverse effects. Pazopanib is a new treatment option and needs further evaluation, particularly on its effect relative to other TKIs as well as its use in combination with other agents.

Abstract
PURPOSE To evaluate the feasibility of laparoscopic simple prostatectomy for large volume prostates. MATERIALS AND METHODS Between October 2007 and July 2009, laparoscopic simple prostatectomy was performed on 16 patients with the prostates over 80 mL. All the patients were operated with transvesical method. Peri-operative and 3rd postoperative month data were recorded and evaluated. RESULTS The mean prostate volume was 147 mL (range, 80 to 200 mL). The mean operation time, blood loss, duration of hospitalization, and duration of drain placement was 133 minutes (range, 75 to 210 minutes), 134 cc (range, 50 to 300 cc), 3.9 days (range, 2 to 7 days), and 2.1 days (range, 2 to 3 days), respectively. Only one patient required blood transfusion due to postoperative bleeding and clot obstruction in the catheter lumen. Postoperative infection was not seen and recatheterization was not needed in any of the patients. All the patients' pathology reports were noted as benign. Pre-operative and postoperative International Prostate Symptom Score were 9.2 and 25.4, respectively. Maximum urinary flow rate was 4.0 mL/sec pre-operatively, but 24.7 mL/sec postoperatively. CONCLUSION Laparoscopic simple prostatectomy is a feasible method with low morbidity and improved postoperative outcomes.

Abstract
BACKGROUND Laparoscopic extraperitoneal adenomectomy is occasionally performed for symptomatic large-volume benign prostatic hyperplasia. Two different multichannel ports were used during operations. We describe the technique of single-port extraperitoneal transvesical adenomectomy and present the initial operative experience. METHODS Three patients in whom an open adenomectomy was indicated underwent single-port extraperitoneal transvesical adenomectomy. Following preparation of the extraperitoneal space via an umbilical incision, a multichannel port was inserted. A transverse cystotomy adjacent to the prostatovesical junction, incision of mucosa overlying the adenoma, subcapsular plane development, prostatic adenomectomy and cystotomy repair were performed as the standard steps of the laparoscopic procedure. RESULTS All cases were completed without conversion to standard laparoscopy. Mean operative time was 105 min. Mean blood loss was 190 ml. Hospital stay was 4 days and catheter duration was 6 days for all patients. No intraoperative or postoperative complication occurred. CONCLUSIONS Single-port extraperitoneal transvesical adenomectomy for large benign prostate hyperplasia is feasible with excellent cosmetic results and minimal morbidity.

Abstract
AIMS We evaluated the prevalence of Helicobacter pylori (HP) in Type 2 diabetic patients and its relationship with dyspeptic symptoms and complications of diabetes. MATERIALS AND METHODS Seventy-eight Type 2 diabetic patients (54 females, 24 males, mean age: 51.9 +/- 10.6 yr) and 71 non-diabetic control subjects were involved in the study. Patients were questioned for dyspeptic symptoms. Cardiovascular autonomic neuropathy, nephropathy and retinopathy were investigated in diabetic patients. Upper gastrointestinal tract endoscopy was performed for all patients and gastric biopsies were obtained and searched for HP. RESULTS Helicobacter pylori prevalence was significantly higher in diabetic patients than in control subjects (75.6 vs 46%, p < 0.05). No differences were found between women and men with regard to HP infection status in diabetic patients. There was no relation between HP and diabetic complications, nephropathy and retinopathy. Helicobacter pylori prevalence was significantly higher in diabetic patients with cardiovascular autonomic neuropathy than in diabetic patients without cardiovascular autonomic neuropathy (90.6 vs 44.0%, p < 0.02). Forty-seven subjects with diabetes had symptoms of dyspepsia (60.3%) and the prevalence of HP was higher in these patients (p < 0.002). CONCLUSION There is a high prevalence of HP infection in diabetic patients and it is correlated with dyspeptic symptoms. Diabetic subjects complicated with cardiovascular autonomic neuropathy and dyspepsia are at high risk of HP infection and should be carefully investigated and considered for eradication therapy.
