Targeting the PANoptosome with 3,4-Methylenedioxy-ß-Nitrostyrene, Reduces PANoptosis and Protects the Kidney against Renal Ischemia-Reperfusion Injury.

OBJECTIVES: The objectives of this study were a) to investigate the effect of targeting the PANoptosome with 3,4-methylenedioxy-ß-nitrostyrene (MNS) on PANoptosis in the Renal ischemia-reperfussion (RIR) model b) to investigate the kidney protective effect of MNS toward RIR injury. METHODS: Thirty-two rats were divided into four groups randomly. The groups were assigned as Control, Sham, DMSO (dimethyl sulfoxide) and MNS groups. The rats in the MNS group were intraperitoneally given 20 mg/kg of MNS 30 minutes before reperfusion. 2% DMSO solvent that dissolves MNS were given to the rats in DMSO group. Left nephrectomy was performed on the rats under anesthesia at the 6th hour after reperfusion. Glutathione peroxidase (GPx), malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD) and 8-Okso-2'-deoksiguanozin (8-OHdG) levels were measured. Immunohistochemical analysis, electron microscopic and histological examinations were carried out in the tissues. RESULTS: Total tubular injury score was lower in the MNS group (p < 0.001). Caspase-3, Gasdermin D and MLK (Mixed Lineage Kinase Domain Like Pseudokinase) expressions were considerably decreased in the MNS group (p < 0.001). Apoptotic index (AI) was found to be low in the MNS group (p < 0.001). CAT and SOD levels were higher in the MNS Group (p = 0.006, p = 0.0004, respectively). GPx, MDA, and 8-OH-dG levels were similar (p > 0.05) in all groups. MNS considerably improved the tissue structure, based on the electron microscopic analysis. CONCLUSIONS: Our results suggested that MNS administrated before the reperfusion reduces pyroptosis, apoptosis and necroptosis. These findings suggest that MNS significantly protects the kidney against RIR injury by reducing PANoptosis as a result of specific inhibition of Nod-like receptor pyrin domain-containing 3 (NLRP 3), one of the PANoptosome proteins.

Comparison of Pelvic Floor Muscle Training With Connective Tissue Massage to Pelvic Floor Muscle Training Alone in Women With Overactive Bladder: A Randomized Controlled Study.

OBJECTIVE: The purpose of this study was to compare the effects of a 6-week program of pelvic floor muscle training (PFMT) plus connective tissue massage (CTM) to PFMT alone in women with overactive bladder (OAB) symptoms on those symptoms, pelvic floor muscle strength, and quality of life. METHODS: Thirty-four participants were randomly divided into PFMT+CTM (n = 17) and PFMT (n = 17) groups. PFMT was applied every day and CTM was applied 3 days a week for 6 weeks. Before treatment, at week 3, and after treatment (week 6), we assessed pelvic floor muscle strength (with a perineometer), bladder symptoms (with a urine diary), OAB symptom severity (with the 8-item Overactive Bladder Questionnaire [OAB-V8]), urgency (with the Patient Perception of Intensity of Urgency Scale [PPIUS]), and quality of life (with King's Health Questionnaire [KHQ]). The Mann-Whitney U test, χ2 test, Friedman test, and Dunn multiple comparison test were used for analysis. RESULTS: In both groups, pelvic floor muscle strength increased, whereas OAB symptoms and PPIUS and KHQ scores decreased after treatment (P < .05). Although the OAB-V8, PPIUS, and KHQ scores decreased at week 3, frequency, OAB-V8, and PPIUS scores, in addition to some parameters of the KHQ, decreased after treatment in the PFMT+CTM group compared to the PFMT group (P < .05). CONCLUSION: Compared to PFMT alone, PFMT+CTM achieved superior outcomes in reducing OAB symptoms in the early and late periods.

Pre-treatment Delta Neutrophil Index as a Predictive Factor in Renal Cell Carcinoma.

OBJECTIVE: To determine the diagnostic value of the pre-treatment delta neutrophil index (DNI) before treatment in patients with renal cell carcinoma (RCC) and to compare this marker with other routine inflammation markers, such as neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Urology, Kahramanmaras Sutcu Imam University, Turkey, from February 2017 to January 2020. METHODOLOGY: Data of patients who underwent radical nephrectomy for RCC, were evaluated. For comparison, healthy individuals were included in the study as a control group. Demographic data, such as age, gender, routine laboratory tests, DNI, NLR, and PLR levels of the groups were recorded and compared. RESULTS: There were 73 patients in the RCC group and 71 healthy individuals in the control group. DNI, NLR and PLR levels were significantly higher in the RCC group (p <0.001, each). DNI and NLR were significantly higher in patients with advanced stage (T3-T4) and high grade (G3-G4). In univariate logistic regression analysis hemoglobin (p=0.023), neutrophil (p<0.001), lymphocyte (p=0.009), platelet (p<0.001), DNI (p<0.001), NLR (p<0.001) and PLR (p<0.001) were identified as predictors for RCC. In multivariate logistic regression analysis, DNI and NLR (p<0.001, each) were found to be the predictors of RCC. Cut-off values were 0.45% for DNI, 1.80 for NLR, and 130.09 for PLR. CONCLUSION: DNI is a new inflammatory marker, which is included in complete blood count parameters; and does not require any additional calculation, unlike NLR and PLR. It can be used in the prediction of RCC. Key Words: Renal cell carcinoma, Delta neutrophil index, Neutrophil-lymphocyte ratio, Platelet-lymphocyte ratio.

Relationship between the G protein-coupled oestrogen receptor and spermatogenesis, and its correlation with male infertility.

The aim of this study was to investigate the diagnostic value of serum G protein-coupled oestrogen receptor (GPER) levels and their correlation with semen parameters in men with infertility. The participants were divided into two groups as follows: 76 fertile control men (Group 1) and 77 infertile men (Group 2). Semen analysis, hormonal evaluation, serum GPER level and scrotal ultrasound of the participants were evaluated. Follicle-stimulating hormone and total testosterone levels were not significantly different between the groups (p = .413 and p = .535 respectively). The oestradiol level in Group 1 was significantly lower than that in Group 2 (p < .001). The serum GPER level was found to be significantly higher in Group 1 than that of Group 2 (p < .001). GPER levels were positively correlated with the total sperm count, sperm concentration, motility and morphology in Group 2 (r = 0.303, 0.345, 0.260 and 0.322, respectively, p < .001). In this study, GPER levels were positively correlated with sperm parameters, and it was hypothesised that the decrease in GPER expression might be associated with male infertility by adversely affecting spermatogenesis.

Ziziphus jujube ameliorated cavernosal oxidative stress and fibrotic processes in cavernous nerve injury-induced erectile dysfunction in a rat model.

The aim of this study was to investigate potential antioxidant and antifibrotic effects of Ziziphus jujube (ZJ) in a cavernosal nerve injury (CNI)-induced erectile dysfunction (ED) rat model. Forty-eight male rats were assigned to six-sized groups as group 1: sham-operated; group 2: sham-operated + low-dose ZJ (200 mg/kg); group 3: sham-operated + high-dose ZJ (400 mg/kg); group 4: CNI + distilled water; group 5: CNI + low-dose ZJ; and group 6: CNI + high-dose ZJ. At the end of 2 weeks, intracardiac blood was taken and rats were sacrificed. For biochemical analysis, cavernosal transforming growth factor-beta-1, collagen type I and type 3, fibronectin, α and ß actin were examined in plasma and cavernosa. Superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) and prolidase levels were measured in serum to evaluate antioxidant effect of ZJ. Histopathological examination of tissues revealed that highest fibrosis rate was in group 4 (66.84%). Collagen 1 and 3, alpha and beta actin, fibronectin levels were significantly different among groups (p < .05). Differences between plasma SOD, CAT, MDA and prolidase were also significant among those groups (p < .05). In this study, antioxidant and antifibrotic effects of ZJ were determined in the corporal tissue after CNI. It is thought that ZJ may be beneficial on ED patients especially after radical pelvic surgeries.

Losartan treatment significantly attenuates the fibrotic changes in the corpus cavernosum of castrated rats / El tratamiento con losartán atenúa de manera importante los cambios fibróticos en el cuerpo cavernoso de ratas castradas

INTRODUCTION AND OBJECTIVES: The aim of this study is to evaluate the effects of castration and subsequent losartan administration on the fibrosis-related parameters in the corpora cavernosa of castrated rats. MATERIAL AND METHODS: Twenty-four male rats were divided into four equal groups. Group 1:sham surgery plus vehicle (0.9% NaCl) (control:con), group 2:sham surgery plus losartan (con+los), group 3: castration plus vehicle (castration:cast) and group 4:castration plus losartan (cast+los). After four weeks of oral losartan treatment, corporal levels of transforming growth factor-beta (TGF-beta), thrombospondin-1 (TSP-1), alpha-actin, beta-actin and fibronectin were investigated by ELISA kits. Changes in the collagen and smooth muscle content were evaluated by histological analysis with Masson trichrome staining. RESULTS: Initial and post-treatment body weights of rats were similar among groups. Castration significantly increased the expression of TGF-beta, TSP-1 and fibronectin and resulted in a significant decrease in alpha-actin levels in the corpora cavernosa. Administration of losartan reduced the levels of TGF-beta, TSP-1 and fibronectin in castrated rats. Alpha actin levels also increased after losartan treatment. Beta-actin levels were not significantly different among 4 groups. The levels of all markers were similar in group 1 and 2. Rate of fibrosis was significantly higher in castrated rats and treatment with losartan reduced this rate. CONCLUSION: Castration increased the expression of fibrosis-related markers in the corpora cavernosa of rats. Administration of losartan significantly attenuated those changes and exerted an antifibrotic effect

INTRODUCCIÓN Y OBJETIVOS: El objetivo de este estudio es evaluar los efectos de la castración y la posterior administración de losartán en los parámetros relacionados con la fibrosis en los cuerpos cavernosos de ratas castradas. MATERIAL Y MÉTODOS: Veinticuatro ratas macho se dividieron en 4 grupos iguales. Grupo 1: cirugía simulada más vehículo (0,9% NaCl) (control:con); grupo 2: cirugía simulada más losartán (con+los); grupo 3: castración más vehículo (castración:cast) y grupo 4: castración más losartán (cast+los). Después de 4 semanas de tratamiento oral con losartán se analizaron los niveles de factor de crecimiento transformante beta (TGF-beta), trombospondina-1 (TSP-1), alfa-actina, beta-actina y fibronectina mediante kits de ELISA. Cambios en el colágeno y el contenido de músculo liso se evaluaron mediante análisis histológico con tinción con tricrómico de Masson. RESULTADOS: Los pesos corporales iniciales y posteriores al tratamiento de las ratas fueron similares entre los grupos. La castración aumentó considerablemente la expresión de TGF-beta, TSP-1 y fibronectina, y dio como resultado una disminución importante de los niveles de alfa-actina en los cuerpos cavernosos. La administración de losartán redujo los niveles de TGF-beta, TSP-1 y fibronectina en ratas castradas. Los niveles de alfa-actina también aumentaron después del tratamiento con losartán. Los niveles de beta-actina no fueron muy diferentes entre los 4 grupos. Los niveles de todos los marcadores fueron similares en los grupos 1 y 2. La tasa de fibrosis fue mucho mayor en las ratas castradas y el tratamiento con losartán redujo esta tasa. CONCLUSIÓN: La castración aumentó la expresión de marcadores relacionados con la fibrosis en los cuerpos cavernosos de las ratas. La administración de losartán atenuó considerablemente esos cambios y ejerció un efecto antifibrótico

Sexual dysfunction and distress in premenopausal women with migraine: association with depression, anxiety and migraine-related disability.

Migraine is a chronic disorder associated with impaired quality of life as well as sexual function. However, data about the sexual distress in women with migraine were lacked.This study aimed to determine the incidence and associated risk factors of both sexual function and distress in premenopausal women with migraine. Sixty-nine women diagnosed with migraine were included. Sexual function and distress were assessed by Female sexual function index (FSFI) and Female sexual distress scale-revised (FSDS-R), respectively. Depression and anxiety were investigated by Hospital depression and anxiety scale (HADS). Migraine related disability was evaluated by Migraine disability assessment scale (MIDAS) and average severity of pain was determied by Visual analog scale (VAS). Fifty-five women reported to have sexual dysfunction. Any headache-related feature including MIDAS and VAS scores, depression or anxiety was found to be related with sexual dysfunction. Sexual distress was noted in 37 cases, and depression, VAS and MIDAS scores were significantly higher in women with sexual distress. This study showed that women with migraine should be screened both for sexual dysfunction and distress to help clinicians dealing with sexual medicine to improve the standart of patient care in their regular practice. Special attention should be given to the ones whose MIDAS and VAS scores were high and who had depression.

Ureteroscopy With Holmium:Yag Laser Lithotripsy for Ureteral Stones in Preschool Children: Analysis of the Factors Affecting the Complications and Success.

OBJECTIVE: To evaluate the factors that may affect the efficacy and safety of ureteroscopy with holmium:YAG laser lithotripsy in the management of ureteral stones in preschool children. MATERIALS AND METHODS: Medical records of 70 children, 32 boys and 38 girls, who were treated for ureteral stones at our clinic between 2014 and 2016 were retrospectively reviewed. Patients were grouped according to size of the instrument used as group 1 (n = 40, ultrathin 4.5 Fr) and group 2 (n = 30, 7.5 Fr). Patient age, stone characteristics, and operative and postoperative outcomes were compared. The effect of age, stone size and location, type of the instrument, and operative times on success and complication rates were also investigated. In addition, factors related with postoperative hydronephrosis were evaluated. RESULTS: Patients in group 1 were significantly younger than group 2 (32.22 ± 22.72 vs 63.53 ± 16.98 months, P = .000). Groups were similar in terms of gender, stone laterality, size and location, and operative times. However, access failure rate was significantly higher in group 2 (0 vs 20%, P = .022). Stone-free rate was 87.5% in group 1 and 76.6% in group 2 (P = .237), complication rates were not significantly different among groups. Stone size and location were found to be associated with success rates. Stone location and operative times were the factors affecting the complication rates. Presence of preoperative hydronephrosis and prolonged operative time were determined as the predictors of postoperative hydronephrosis. CONCLUSION: Ultrathin ureteroscopy with laser lithotripsy can be used safely and effectively for ureteral calculi including proximal ones in significantly younger children without any access failure.

Deterioration of Chronotropic Responses and Heart Rate Recovery Indices in Men With Erectile Dysfunction.

INTRODUCTION: Erectile dysfunction (ED) and cardiovascular (CV) diseases share common risk factors and ED has been accepted as an early manifestation of CV disease. Exercise stress testing (EST) is used to evaluate CV functions in men with ED. Low exercise workload, a slower heart rate recovery (HRR) after exercise, and inability to increase heart rate during EST (chronotropic incompetence) are independent negative predictors of adverse CV outcomes. AIM: To assess the association among EST parameters, ED, and testosterone levels. METHODS: The study population consisted of 41 patients with ED and 40 controls. All participants underwent treadmill EST to assess cardiac autonomic functions. HRR indices were calculated by subtracting 1st (HRR1), 2nd (HRR2), and 3rd (HRR3) minute heart rates during the recovery period from maximal heart rate. Total exercise duration, exercise capacity and chronotropic response, and plasma testosterone levels were evaluated. Erectile functions were evaluated with the Sexual Health Inventory for Men. Patients were divided into subgroups according to severity and duration of ED. MAIN OUTCOME MEASURES: Mean HRR1 (30.6 ± 11.9 vs 36.9 ± 9.9; P = .01), HRR2 (44.9 ± 12.4 vs 54.9 ± 7.8; P < .001), and HRR3 (50.1 ± 11.7 vs 63.0 ± 7.9; P < .001) were significantly lower in the ED than in the control group. Total exercise duration (9.4 ± 1.9 vs 10.9 ± 1.7 minutes; P < .001), exercise capacity (12.5 ± 1.9 vs 13.6 ± 1.4 metabolic equivalents; P = .004), and chronotropic response (0.88 ± 0.1 vs 1.0 ± 0.1; P < .001) were worse in the ED group. However, we found no association between severity and duration of ED and EST parameters. In addition, serum testosterone levels were significantly correlated with HRR1 (r = 0.36, P = .02) in men with ED. CONCLUSION: Our data suggested that cardiac autonomic functions are impaired in patients with ED. A weak correlation between cardiac autonomic dysfunction and low testosterone levels in patients with ED was noted. However, further studies are needed to elucidate the prognostic significance and clinical implications of impaired autonomic functions and testosterone replacement therapy in patients with ED.

Evaluation of serum prolidase activity and oxidative stress markers in men with BPH and prostate cancer.

BACKGROUND: Prostate cancer (PCa) and benign prostatic hyperplasia (BPH) are diseases of elderly men and are related to increased oxidative stress (OS). Although prolidase has a role in collagen metabolism, it is also used to evaluate OS in many diseases. However, there is a lack of data about serum prolidase activity (SPA) in prostate cancer. The aim of this study was to evaluate and compare SPA levels in males with BPH and PCa. METHODS: Evaluation was made of a total of 81 men who underwent transrectal ultrasound guided prostate biopsy for a definitive diagnosis due to high PSA levels. Patients were separated into 2 groups as BPH and PCa patients. Pre-biopsy malondialdehyde (MDA), superoxide dismutase (SOD), PSA levels and serum prolidase activities (SPA) were compared between the groups and the correlations of SPA with the other parameters were also investigated in both groups. RESULTS: BPH was diagnosed in 51 patients and PCa in 30. The mean age of patients was similar in both groups as 63.25 ± 5.81 years in the BPH group 65.30 ± 7.35 years in the PCa group(p:0.081). The median MDA and SOD levels were insignificantly increased in the PCa patients. SPA values were similar in BPH and PCa patients. SPA did not correlate with age, PSA, MDA or SOD levels in either group. CONCLUSIONS: Our study results revealed that serum prolidase activity is similar in BPH and PCa cases and is not correlated with MDA, SOD or PSA levels.

Management of urinary tract infection with intravesical amikacin may increase the risk of bladder oxidative stress in children with neurogenic bladder.

INTRODUCTION: We evaluated the bladder oxidative stress in neurogenic bladder children treated with intravesical amikacin for recurrent UTI and whether urinary isoprostane f2 alpha (F2-IsoP) is a good biomarker in this particular condition. METHODS: This prospectively designed controlled study was approved by the Adnan Menderes University institutional ethics committee (Adnan Menderes University, 2015/649). Between January 2016 and January 2017, twenty-six children with meningomyelocele who had been doing CIC were recruited. Serum and urine samples were collected during urinary tract infection (UTI) (group 1) and after management of UTI with intravesical amikacin (group 2) besides standard oral antibiotic treatment. While oxidative stress parameters SOD, GSH, GPX, MDA, F2-IsoP and NO were analyzed in the serum samples, only F2-IsoP was analyzed in the urine. All data were compared with 23 normal healthy control children (group 3). RESULTS: Median age, CIC duration and number of CIC per day of patients' group were 84 (60-147) months, 60 (30-90) months and 4 (4-6), respectively. Male-to-female ratio was 1:16. There was no statistical difference between groups in terms of serum oxidative stress parameters (p > 0.05). However, statistically significant urine F2-IsoP changes exist between groups (p = 0.011) (Fig. 1). But there were no correlations between urine F2-IsoP and disease clinical data such as CIC duration or number of CIC per day. Serum glutathione levels in group 2 were higher than group 1 and 3, as well (p = 0.023, Kruskal-Wallis test). Fig. 1 Comparison of median urinary isoprostane f2 alpha levels CONCLUSION: Higher urine F2-IsoP levels after management of UTI with intravesical amikacin may reflect increased lipid peroxidation and oxidative stress in children with NB. This detrimental effect on bladder should be considered in the long-term treatment period.

Evaluation of the diagnostic efficacy of strain elastography in infertile population with normal and abnormal semen parameters.

OBJECTIVE: The aim of the present study was to investigate the diagnostic value of strain elastography (SE) of testicular tissues in infertile population. We also evaluated the correlation between SE results with semen parameters and hormone profiles of the patients. MATERIAL AND METHODS: A total of 61 patients and 122 testes were evaluated. Patients who were evaluated in an andrology outpatient clinic with the diagnosis of infertility and referred to radiology department for investigation of reproductive organs between June 2015 and January 2016 were included. Patients were divided into two groups according to semen analyses results as normal (Group 1) and abnormal (Group 2). Hormone profiles, semen analyses, B-mode, coloured Doppler ultrasonography and sonoelastography examinations were performed for each patient. Measurements of testicular volumes, resistive indices (RI) in intraparenchymal arteries, strain, strain ratio (SR) and presence of varicocele were recorded. RESULTS: Mean age of participants was 33.7±6.3 years. Mean testicular volumes (Group 1, 19.41±4.8 mL, and Group 2, 17.64±3.62 mL) were significantly different between groups (p=0.023). Mean SRs were also different between Groups 1 and 2 (0.12±0.08 vs. 0.22±0.18, p<0.001). Testicular volumes were directly proportional with SRs in Group 1. Strain values had inverse relationship with sperm concentration and total motile sperm counts in Group 2 (p=0.01). SRs were found to be positively correlated with RI and sperm morphology in Group 2 (p<0.05). Although FSH values showed significant difference among groups, any correlation between FSH and elastographic parameters could not be displayed. CONCLUSION: Strain elastography results were found to be significantly different in patients with abnormal sperm counts. This technique may provide promising results, however, further large scale studies may help to clarify the value of this imaging modality in the assessment of male infertility.

Role of Contrast Enhancement and Corrected Attenuation Values of Renal Tumors in Predicting Renal Cell Carcinoma (RCC) Subtypes: Protocol for a Triphasic Multi-Slice Computed Tomography (CT) Procedure.

BACKGROUND: To distinguish RCC subtypes based on contrast enhancement features of CT images. MATERIAL/METHODS: In total, 59 lesions from 57 patients were included. All patients underwent multi-slice CT imaging with a triphasic protocol, which included non-contrast, corticomedullary, nephrographic and urographic phases. Contrast enhancement features of renal masses were evaluated in terms of CT attenuation values (AV) and differences in contrast density; the aorta or renal parenchyma were evaluated based on corrected or relative values. RESULTS: Clear cell RCC (ccRCC) showed more intense contrast enhancement than other RCC subtypes. When differentiating ccRCC from other RCC subtypes, a cut-off AV of 86-89 HU, aorta-based corrected AV of 89-95 HU and renal parenchyma-based corrected AV of 87-95 HU showed a diagnostic accuracy of 81-86%, 86-88% and 74-78%, respectively, in the corticomedullary phase. Furthermore, a cutoff of 2.42-2.72 for the relative contrast enhancement ratio, a cutoff of 2.59-2.74 for the aorta-based corrected relative contrast enhancement ratio and a cutoff of 2.63-2.76 for the renal parenchyma-based attenuation ratio showed a diagnostic accuracy of 83-88%, 88-90% and 81%, respectively. CONCLUSIONS: The most reliable parameters for differentiating ccRCC from other RCC subtypes are aorta-based corrected AV and aorta-based corrected relative contrast enhancement values in the corticomedullary phase.

Comparison of Two Different Methods Used for Semen Evaluation: Analysis of Semen Samples from 1,055 Men.

The aim of this study was to evaluate whether there is a difference between gravimetrically and volumetrically measured semen samples and to assess the impact of semen volume, density, and sperm count on the discrepancy between gravimetric and volumetric methods. This study was designed in an andrology laboratory setting and performed on semen samples of 1,055 men receiving infertility treatment. Semen volume was calculated by gravimetric and volumetric methods. The total sperm count, semen density and sperm viability were also examined according to recent version of World Health Organization manual. The median values for gravimetric and volumetric measurements were 3.44 g and 2.96 ml respectively. The numeric difference in semen volume between 2 methods was 0.48. The mean density of samples was 1.01 ± 0.46 g/ml (range 0.90-2.0 g/ml). The numeric difference between 2 methods gets higher as semen volume increases (p < 0.001). Gravimetric and volumetric semen volume measurements were strongly correlated for all samples and for each subgroup of semen volume, semen density and sperm count, with minimum correlation coefficient of 0.895 (p < 0.001). In conclusion, the gravimetric measurement provides higher results than volumetric one and numeric differences between 2 methods increase as semen volume increases. However, further studies are needed to offer the use of gravimetrical method, which was thought to minimize laboratory errors, particularly for a high amount of semen samples.

Prevalence and correlates of female sexual dysfunction among Turkish pregnant women.

OBJECTIVE: The aim of the present study was to determine the prevalence and associated factors of female sexual dysfunction together with the concerns of women about sexuality during pregnancy. MATERIAL AND METHODS: A total of 207 healthy, sexually active pregnant women were enrolled in the study. Demographic data of all participants were noted and sexual functions were evaluated by Female Sexual Function Index (FSFI). Each FSFI domain score was calculated and mean scores were noted. Concerns of women about sexuality were also investigated. RESULTS: Mean age of participant women was 27.0±5.9 (range 15-44) years. Prevalence of sexual dysfunction was found to be 87% in study population. Mean FSFI score was 18.6±1.21. The rate of sexual dysfunction was higher in the first (87%) and third (92.6%) trimesters when compared to the second (80.6%) trimester (p=0.243). Among demographic variables, education levels of partners and preconceptional sexual dysfunction were found to be significantly related to FSD. The most common concerns of women about sexual relationship have been reported as the fear of having pain (35%), risk of abortion (21.3%) and religious factors (10%). CONCLUSION: Prevalence of sexual dysfunction is relatively high among pregnant women. Educational levels and preconceptional sexual functions were found to have an impact on this high rate. Accurate counseling of partners about sexuality during pregnancy may help to reduce misbeliefs, concerns and, thereby, decrease this high rate of female sexual dysfunction.

A Comparison of Sexual Function, Psychological Status, and Sociodemographic Characteristics of Turkish Men within Polygamous and Monogamous Marriages.

BACKGROUND: A limited number of studies within the literature have entailed objective evaluations of psychological, sexual, and emotional features of women within polygamous marriages. However, there is a lack of studies reporting these features among polygamous and monogamous men. AIMS: The aim of this study was to investigate sociodemographic characteristics, sexual function, and psychological status of polygamously and monogamously married men. STUDY DESIGN: Cross-sectional study. METHODS: The study sample comprised two groups: 35 polygamous and 45 monogamous men in Kahramanmaras Province, Turkey. Door-to-door surveys covered sociodemographic factors and adopted Beck Depression Inventory (BDI), and International Index of Erectile Function - Erectile Function Domain (IIEF-EFD) scales. RESULTS: Polygamous men showed considerably higher IIEF-EFD scores (p<0.05). While the median score of IIEF-EFD was 25.0 for polygamous men, it was 22.0 for monogamous men. A comparison of the two groups revealed that polygamous men had lower BDI scores. However, the difference between the groups was statistically non-significant (p>0.05). Odds ratios and 95% confidence intervals of monogamous men for erectile dysfunction and depression were 14.4 (95% CI: 3.1-67.5) and 7.4 (95% CI: 0.9-61.9), respectively. The main reasons for multiple marriages reported by polygamous men, in descending order, were: 1) decreased satisfaction of sexual desires by a wife (37.1%); 2) falling in love with the second wife (22.8%); and 3) incompatibility with the first wife (17.1%). However, 62.9% of them responded negatively to the question: "Would you recommend polygamous marriage to other men?" CONCLUSION: Our results showed that polygamous men had higher erectile function and lower depression scores than monogamous men. Further studies investigating the effects of polygamy on men's psychosexual function are warranted. Additionally, studies that address the perspectives of offspring and women's expectations within polygamous marriages should be conducted.

Huge Pyogenic Granuloma of the Penis.

Pyogenic granulomas are benign vascular disorders of the skin and mucose membranes, generally developed by trauma and irritation. The lesions are generally small. They are most commonly seen in the skin and oral mucosa and rarely seen on penis. We present the case of a huge pyogenic granuloma on the penis.

Cognitive, Affective Problems and Renal Cross Ectopy in a Patient with 48,XXYY/47,XYY Syndrome.

Klinefelter syndrome is the most common sex chromosome abnormality (SCA) in infertile patients and 47,XXY genomic configuration constitutes most of the cases. However, additional Xs and/or Y such as 48,XXYY, 48,XXXY, and 47,XYY can occur less frequently than 47,XXY. Those configurations were considered as variants of Klinefelter syndrome. In this report, we present an infertile man with tall stature and decreased testicular volume. Semen analysis and hormonal evaluation supported the diagnosis of nonobstructive azoospermia. Genetic investigation demonstrated an abnormal male karyotype with two X chromosomes and two Y chromosomes consistent with 48,XXYY(17)/47,XYY (13). Additionally, the patient expressed cognitive and affective problems which were documented by psychomotor retardation and borderline intelligence measured by an IQ value between 70 and 80. Systemic evaluation also revealed cross ectopy and malrotation of the right kidney in the patient. The couple was referred to microtesticular sperm extraction (micro-TESE)/intracytoplasmic sperm injection (ICSI) cycles and preimplantation genetic diagnosis (PGD). To the best of our knowledge, this is the first report of combination of XYY and XXYY syndromes associated with cognitive, affective dysfunction and renal malrotation.

Endoscopic removal of intravesical polypropylene suture with plasmakinetic resection after abdominal hysterectomy.

INTRODUCTION: Intravesical foreign substances such as mesh or suture are among the rare reasons of recurrent urinary tract infections. Anti-incontinence and prolapsus procedures are associated with mesh/suture extrusion into the bladder, however, this complication is uncommon with abdominal hysterectomy. PRESENTATION OF CASE: A 61-year-old female, obese patient admitted to our clinic with recurrent urinary tract infections and voiding symptoms which were worsened after abdominal hysterectomy. Radiological evaluation revealed an intravesical foreign material within the bladder. The cytoscopy was performed and a polypropylene suture which was inserted from dome, passed through the base and exited from the dome of bladder during abdominal hysterectomy. Transurethral plasmakinetic resection of superficial layer of urothelium between suture entrance and exit sites was performed and suture was removed from the bladder. DISCUSSION: Urogynecological procedures are associated with the increased risk of urethral or ureteral injury, intravesical mesh or suture erosion and fistulae formation. Many different techniques including open, laparoscopic and transvaginal approaches were described for the removal of intravesical mesh/suture extrusion in the literature. Transurethral approach with its minimally invasive and safe nature was used to remove suture in this patient. This technique with the use of plasmakinetic energy has the advantage of decreased risk of bleeding and urothelial injury when compared to monopolar cautery. It also avoids the need for open or extensive surgery which may have a high rate of complications. CONCLUSION: Transurethral resection is the treatment of choice for the removal of intravesical foreign substances. Use of plasmakinetic energy will decrease the risk of complications and avoid the need for open interventions.
