RESUMEN

Key reproductive events such as fertilization and early embryonic development occur in the lumen of the oviduct. Since investigating these processes in vivo is both technically challenging and ethically sensitive, cell culture models have been established to reproduce the oviductal microenvironment. Compartmentalized culture systems, particularly air-liquid interface cultures (ALI; cells access the culture medium only from the basolateral cell side), result in highly differentiated oviduct epithelial cell cultures. The oxygen (O2) tension within the oviduct is 4-10% across species, and its reduced O2 content is presumed to be important for early reproductive processes. However, cell culture models of the oviduct are typically cultivated without O2 regulation and therefore at about 18% O2. To investigate the impact of O2 levels on oviduct epithelium functions in vitro, we cultured porcine oviduct epithelial cells (POEC) at the ALI using both physiological (5%) and supraphysiological (18%) O2 levels and two different media regimes. Epithelium architecture, barrier function, secretion of oviduct fluid surrogate (OFS), and marker gene expression were comparatively assessed. Under all culture conditions, ALI-POEC formed polarized, ciliated monolayers with appropriate barrier function. Exposure to 18% O2 accelerated epithelial differentiation and significantly increased the apical OFS volume and total protein content. Expression of oviduct genes and the abundance of OVGP1 (oviduct-specific glycoprotein 1) in the OFS were influenced by both O2 tension and medium choice. In conclusion, oviduct epithelial cells can adapt to a supraphysiological O2 environment. This adaptation, however, may alter their capability to replicate in vivo tissue characteristics.

RESUMEN

Background and purpose:

Neuropathic pain may appear as one of the first symptoms that take the patient to the physician in type 2 diabetes, which can be asymptomatic for years. Although it is accepted that diabetes is a trigger for vascular inflammation, it has been suggested that inflammation itself may trigger diabetes. In our study, we aimed to investigate the relationship between diabetic polyneuropathy and neuropathic pain and inflammatory markers.

. Methods:

The study included 44 healthy controls, 46 diabetic patients with normal electroneuromyography (ENMG) and 44 diabetic patients with polyneuropathy detected in ENMG. Sedimentation, C-reactive protein (CRP), Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLO) and mean platelet volume (MPV) values were recorded in the sera of the patients. The Douleur Neuropathic 4 (DNP4) Questions was used to evaluate the presence of neuropathic pain in the patients, and the Visual Analogue Scale (VAS) was used to evaluate the severity of pain.

. Results:

NLR, CRP, sedimentation levels were statistically significantly higher in the DMP+ and DMP– patient groups compared to the control group. PLO and MPV levels were significantly higher in the DMP+ patient group compared to both the DMP– patient group and the control group. 
The means of VAS and DN4 scores were statistically significantly higher in the DMP+ patient group than in the DMP– patient group. In the DMP– patient group, the NLR levels of those with neuropathic pain according to the DN4 scale were statistically significantly higher than those without neuropathic pain.

. Conclusion:

Diabetic neuropathy is one of the common complications of diabetes, affecting about half of patients. Our study shows that NLR, PLO, MPV values can be used as parameters to help us make an easy and fast diagnosis in diabetic polyneuropathy. However, their reliability in the diagnosis of diabetic polyneuropathy should be evaluated with studies to be conducted with larger patient and control groups.

RESUMEN

Purpose: The aim of this study is to investigate the effect of bladder neck plication during transperitoneal robot-assisted radical prostatectomy (tRARP) on orgasm-related incontinence (climacturia) and the relationship between International Index of Erectile Function 5 (IIEF-5) scores and climacturia. Materials and Methods: We evaluated 118 patients who underwent nerve-sparing tRARP in our clinic and survived the first postoperative year. Patients were divided into two groups: those who underwent bladder neck plication (Group 1, n = 58) and those who did not (Group 2, n = 60). Our study investigated whether there is a difference between the groups in terms of climacturia or if there is a relationship between IIEF-5 scores and climacturia. Results: Of the patients in Group 1, 10.3% had incontinence and 13.8% had climacturia. Of the patients in Group 2 who did not have bladder neck plication, 10% had incontinence and 15% had climacturia. There was no difference between the groups in terms of climacturia (P > .825). Three patients (5.2%) in Group 1 and four patients (6.6%) in Group 2 requested treatment. There was no statistically significant correlation between IIEF-5 scores and climacturia in both groups (Group 1, P > .208; and Group 2, P > .508). Conclusions: In our study, the frequency of climacturia in patients who underwent bladder neck plication during tRARP was consistent with the literature and did not show a statistically significant difference from patients who did not undergo bladder neck plication. It has been observed that bladder neck plication, which has no effect on long-term continence, does not contribute to prevention of climacturia. No correlation was found between IIEF-5 scores and climacturia.

RESUMEN

Background: The aim of the study is to examine the effect of peritoneal re-approximation or non-approximation on the postoperative course of patients at the end of transperitoneal robot-assisted radical prostatectomy (tRARP). It is also aimed to examine the relationship between peritoneal re-approximation or non-approximation and drain removal time, need for analgesics, passage of flatus, and length of hospital stay. Methods: A total of 247 patients who underwent tRARP by 2 different experienced surgeons were included in the study. At the end of the tRARP procedure, 1 surgeon performed peritoneal re-approximation (Group 1, n = 108), whereas the other performed peritoneal non-approximation (Group 2, n = 139). The effect of the procedures on drain removal time, passage of flatus, need for analgesics, and length of hospital stay were compared between the groups. Results: There was no significant difference between the groups in terms of preoperative parameters including age, body mass index, and preoperative prostate-specific antigen levels (P > .05) (P = .622, P = .126 and P = .591, respectively). No statistically significant difference was found between the two groups in terms of comorbidity, Gleason score, clinical stage, and lymph node dissection (P = .086, P = .344, P = .318, P = .587, respectively). There was no statistically significant difference between the groups in terms of drain removal time, need for analgesics, passage of flatus, and length of hospital stay (P = .095, P = .142, P = 95, P = .389, respectively). Conclusion: This study did not demonstrate any additional postoperative benefit of peritoneal re-approximation. It has been shown that peritoneal re-approximation has no effect on the length of hospital stay, the need for pain relievers, and passage of flatus, drain duration, day. Therefore, we do not recommend re-approximation of the peritoneum.

RESUMEN

PURPOSE: To evaluate the clinical results of arthroscopic repair and open Ahlgren-Larsson method in patients with chronic lateral ankle instability. METHODS: We retrospectively evaluated 60 patients who were operated in our clinic between 2010 and 2018 with the diagnosis of chronic lateral ankle instability. Preoperative and postoperative clinical evaluations were performed with AOFAS ankle-hindfoot score, FAOS, and VAS scores. RESULTS: Sixty patients with chronic lateral ankle instability were evaluated. 28 patients were treated with Ahlgren-Larsson method, and 32 patients were treated with arthroscopic repair. Follow-up duration was 35 ± 12 months for the open surgery group and 19 ± 2 months for the arthroscopic surgery group. The mean age of the arthroscopy group was 44 ± 9; the mean age of the open surgery group was 46 ± 11. There was no significant difference between the groups in terms of demographic features (age, sex, BMI). Postoperative clinical improvement was observed in both groups. There was no statistically significant difference between the groups in terms of functionality. However, there was a statistically significant difference in VAS in terms of pain and patient satisfaction in favor of arthroscopy group. CONCLUSIONS: Ahlgren-Larsson method and arthroscopic repair technique are safe and effective for chronic lateral ankle instability. Arthroscopic technique may be preferred for pain and patient satisfaction as it is less invasive and less morbid. LEVEL OF EVIDENCE: II.

RESUMEN

OBJECTIVE: To evaluate the correlation between Visual Prostate Symptom Score (VPSS) and the International Prostate Symptom Score (IPSS) and uroflowmetry parameters in men with lower urinary tract symptoms (LUTS) with literature review. METHODS: Patients were pooled from 4 different urology clinics in Turkey and divided into 3 groups according to their educational level. The scores of IPSS and the VPSS questionnaire, assistance requirement, and completion time of the questionnaires were recorded. Maximum flow rate (Qmax) and average flow rate (Qave) were determined with uroflowmetry test and the results are recorded. RESULTS: A total of 342 patients were evaluated (group 1, n = 168; group 2, n = 108; group 3, n =66). Median age of all groups was 61 (40-89). There was a significantly higher rate of the completion of VPSS than IPSS without assistance in total (P < .001). Educational level was not found as an independent factor with assistance requirement to complete VPSS while university educational level was found as an independent factor to complete IPSS (odds ratio = 9.735, P < .001).There was a significantly lower completion time for VPSS in all groups when compared to IPSS (P < .001 for all groups). Significant positive correlations were found between VPSS and IPSS questions (P < .001). There were significant negative correlations between total score and weak stream question of VPSS and Qmax and Qave, separately (P < .001). CONCLUSION: VPSS can be more practical than IPSS to evaluate LUTS in men with low educational levels and/or in large populations. Some modifications are needed to increase the availability of VPSS.

RESUMEN

OBJECTIVE: To assess the safety and efficacy of patient-specific three-dimensional (3D) rapid-prototype printing technology for pedicle screw insertion in patients with adolescent idiopathic scoliosis (AIS). METHODS: The 3D pedicle screw guides were produced after selecting the fixation points for all individual levels to be used intraoperatively. Preoperative computed tomography images recreated 3D bone models of each vertebra specific to each patient. Safe pedicle trajectories were determined in all 3 planes on these models. 3D printed guides were modeled according to these trajectories and manufactured with a biocompatible material. Postoperatively, all screws were evaluated and scored with computed tomography as class 1 (accurate), class 2 (inaccurate), or class 3 (deviated). The mean angle between the inserted pedicle screw and the intended trajectory, and the mean distance between the central longitudinal axis of a screw and pedicle were also measured. RESULTS: A total of 134 screws were inserted. On the concave and convex sides, the mean medial malposition was 0.5 ± 0.8 and 0.4 ± 0.6 mm, the mean lateral malposition was 1.4 ± 2.3 and 0.8 ± 1.3 mm, angle between the inserted pedicle screw and the intended trajectory was 4.2 ± 4.6 and 4.3° ± 6.0°, and distance between the central longitudinal axis of a screw and pedicle was 1.5 ± 2.1 and 0.9 ± 1.2 mm, respectively. A total of 117 screws were regarded as class 1, 14 as class 2, and 3 as class 3. Of all screws inserted, 92.5% achieved positional accuracy. There were no screw-related complications. CONCLUSIONS: This is one of the initial reports to note the novel design and implementation of patient-specific 3D pedicle screw guides for adolescent idiopathic scoliosis surgery. Our pilot study shows that the use of these low-cost personalized 3D guides is completely safe and effective in both convex and concave sides of the curves.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the clinical outcomes and the coronal correction rate of the main and accompanying curves of adolescent idiopathic scoliosis (AIS) corrected with pedicle screws inserted consecutively or intermittently. METHODS: The prospectively collected data of 60 patients (8 men and 52 women; mean age: 14.6±2.5 years) who underwent corrective surgery for AIS between January 2010 and December 2015 were reviewed retrospectively. Two groups were constituted according to the pedicle screw construct type: consecutive pedicle screw construct (CPSC) and intermittent pedicle screw construct (IPSC) groups. The preoperative, early postoperative, and 24-month follow-up radiographs and the Scoliosis Research Society-22 (SRS-22) scores were reevaluated. The Cobb angle of the main and accompanying curves, the correction rate, and the flexibility of the curves were calculated. RESULTS: The mean preoperative Cobb angles were 57.03° and 57.46°, the mean postoperative Cobb angles were 14.93° and 14.4°, and the mean correction rates were 76.22% and 75.31% in IPSC and CPSC groups, respectively (p>0.05). The preoperative and postoperative accompanying curve magnitudes and correction rates were similar (p>0.05). These radiographic outcomes were also consistent with the SRS-22 scores. CONCLUSION: Both the pedicle screw constructs had satisfactory outcomes following the surgery, which were confirmed by both the SRS-22 scores and radiographs taken perioperatively and at follow-ups. The IPSC and CPSC groups did not demonstrate a significant change in the correction rate of the main and minor or major accompanying structural and nonstructural curves, and also in the SRS-22 scores. LEVEL OF EVIDENCE: Level III, Retrospective comparative study.

RESUMEN

OBJECTIVES: This study aims to compare two single-step arthroscopic techniques, microfracture and cell-free scaffold implantation, in the treatment of talar osteochondral lesions (OCLs) clinically and radiologically. PATIENTS AND METHODS: This retrospective study included 62 patients (35 males, 27 females; mean age 41±13 years; range, 15 to 65 years) diagnosed with talar OCLs between March 2007 and January 2015. Patients who were followed-up with a minimum of 24 months with lesions larger than 1 cm2 were included. Pre- and postoperative clinical evaluations were performed according to the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and radiological evaluations according to the magnetic resonance observation of cartilage repair tissue (MOCART) scale. RESULTS: Patients were divided into microfracture (n=22) and scaffold (n=40) groups. The mean follow-up duration was 36.1±14.9 months. The mean preoperative AOFAS score increased from 60.6±13.9 to 82.1±11.8 in the microfracture group (p<0.001) and from 53.8±13.6 to 89.4±9.9 in the scaffold group (p<0.001). The scaffold group had superior results than the microfracture group clinically (p=0.011). Clinical results were superior in younger patients (<45 years) (p=0.018), male patients (p=0.020), and traumatic lesions (p=0.014). There was no significant difference between the two techniques according to the total MOCART scores (p=0.199). However, the scaffold technique was more successful in terms of lesion border and effusion subgoups of MOCART scale. CONCLUSION: Both single-step arthroscopic techniques are effective and safe in the treatment of talar OCLs. The scaffold technique showed superior clinical results than the microfracture technique in short-term follow-up. Age, trauma history and gender significantly affected the treatment outcomes. The scaffold technique can be considered as a safe and good alternative particularly in the treatment of large lesions.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the effects of human recombinant epidermal growth factor (EGF) on posterolateral lumbar fusion in a rat model. METHODS: 36 male Sprague Dawley rats underwent posterolateral fusion at L4-5 level. They were randomly assigned to 3 groups: 1- Sham control group where no local augmentation was made, 2- Local Hydoxyapatite ß-tricalcium phosphate (HA/ß-TCP) augmentation group and 3- Local HA/ß-TCP + EGF augmentation group. Rats were euthanized at 8 weeks post-surgery. 6 rats from each group were selected for manual palpation examination, micro-computed tomography analysis and histologic analysis; and the rest was used for biomechanical analysis. RESULTS: Based on manual palpation, there was no fusion in the sham control group. Fusion rate was 33.3% in the HA/ß-TCP group and 66.7% in the HA/ß-TCP + EGF group (p = 0.085). Micro-CT results revealed that new bone formation was higher in the HA/ß-TCP + EGF group (BV/TV: 40% vs. 65%) (p = 0.004). Histologically newly formed bone tissue was more pronounced in the EGF group and compacted and bridging bone spicules were observed. The median maximum bending moment values were 0.51 Nmm (0.42-0.59), 0.73 Nmm (0.49-0.88) and 0.91 Nmm (0.66-1.03) in the sham control, HA/ß-TCP and HA/ß-TCP + EGF groups, respectively (p = 0.013). The median stiffness values were 1.69 N/mm (1.12-2.18), 1.68 N/mm (1.13-2.74) and 3.10 N/mm (1.66-4.40) as in the previous order (p = 0.087). CONCLUSION: This study demonstrates that EGF enhances posterolateral lumbar fusion in the rat model. EGF in combination with ceramic grafts increased the fusion rates. Our findings may provide insights to further studies, investigating EGF's clinical usage as an alternative fusion enhancer.

RESUMEN

PURPOSE: Erectile dysfunction (ED) is a sexual dysfunction described as the inability to develop or maintain an erection of the penis adequate for sexual intercourse, and its prevalence increases with age. Seen as a common sexual disorder worldwide, organic causes are the underlying reason for 80 percent of ED cases, with the most characteristic pathology responsible for organic ED being atherosclerosis. This study investigates the diagnostic value of plasma PTX-3 levels in arterial ED. MATERIALS AND METHODS: This study included a total of 45 patients who were admitted to the urology and cardiologyoutpatient clinics of the Medical Faculty of Canakkale Onsekiz Mart University (COMU) and consented to participate in this study. Patients were categorized into three equal groups in number: (1) patients with ED diagnosed with coronary artery disease (CAD) (15 patients in total); (2) patients with ED not having coronary artery disease or any other equivalent diseases (diabetes mellitus, hypertension and hyperlipidemia) (15 patients in total);and (3) ordinary patients with no ED (15 patients in total). An interview was conducted at the andrology polyclinic with each patient in order to ascertain detailed information on their medical and sexual history and on demographic characteristics. All patients were also administered the International Index of Erectile Function (IIEF) questionnaire. RESULT: The findings from this study investigating the diagnostic value of plasma PTX-3 levels in ED were statistically significant for two comparisons: the differences between the peripheral blood and cavernous blood values of the patient groups (group 1 and 2) and the control group (group 3), and the differences between the peripheral blood and cavernous blood values of group 2 (patients with ED who do not have CAD) and the control group (group 3). CONCLUSION: As PTX-3 is more specific than the formerly recognized biochemical markers in endothelial dysfunction, it can be used in the diagnosis of vascular originated ED.

RESUMEN

PURPOSE: The aim of this study was to define a sutureless peripheral nerve repair technique with a vein graft and bone marrow-derived stem cells (BMSC) and compare it to epineural repair. MATERIALS AND METHODS: Thirty Wistar Albino rats were divided into five groups evenly. In the control group (C), epineural repair was performed. In the SV (suture + vein) and MSV (BMSC + suture + vein) groups, epineural repair was wrapped with a vein graft. In the V (vein) and MV (vein + BMSC) groups, sutureless repair using a vein graft was performed by taking sutures away from the regeneration site. Rats were evaluated with pinprick, toe spread tests and sciatic nerve index (SFI) at 4th, 8th, and 12th weeks. They were sacrificed at 12th week, repair sites were harvested and evaluated immunohistochemically. RESULTS: There was no difference in pinprick and toe spread tests between the groups at 12th week. The mean SFI was -76.5 ± 3.7, -65.2 ± 11.7, -46.2 ± 19.4, -68.8 ± 9.8, -56 ± 8.8 in the C, SV, MSV, V, MV groups, respectively. The MSV group showed significantly the best SFI results (P < .05). NF-H immunostaining scores were as C; 1 ± 0.18, SV; 2.5 ± 0.36, MSV; 4 ± 0.49, V; 1.56 ± 0.54, MV; 3 ± 0.39, whereas GAP-43 scores were as C; 1 ± 0.31, SV; 2.66 ± 0.56, MSV; 4.50 ± 0.23, V; 2 ± 0.23, MV; 3 ± 0.6. The best nerve regeneration according to immunostaining results was observed in the MSV group (P < .05). The mean fibrosis area was 221.5 ± 25.9, 101.6 ± 7.1, 121.3 ± 18.8, 150.3 ± 12.1, 152.4 ± 11.8 µm2 in the above groups, respectively. SV and MSV groups showed the significantly less fibrosis area (P < .05). CONCLUSION: Epineural suture repair combined with vein wrapping and BMSCs (MSV) showed the best SFI, GAP-43, and NF-H immunostaining results.

RESUMEN

PURPOSE: To report the clinical and radiological results of patients with talar osteochondral lesions who were treated by microfracture and cell-free scaffold implantation in a single-step arthroscopic surgery. METHODS: Forty patients, treated with a single-step arthroscopic surgery, were evaluated in this single-center-based retrospective study. Patients with degenerative arthritis (n = 1), history of ankle fracture (n = 1), kissing lesions (n = 1), lower extremity deformity (n = 1), and lesions <1.5 cm2 (n = 4) were excluded. Oversized (>10 mm depth) bone cysts were additionally treated with bone graft. Patients were evaluated clinically, using the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score. Radiological assessment was performed with magnetic resonance imaging, using the magnetic resonance observation of cartilage repair tissue (MOCART) score. RESULTS: Thirty-two patients with a mean age of 38 ± 12 years were evaluated. The mean defect size was 2.5 ± 0.8 cm2 and the mean defect volume was 2.4 ± 1.9 cm3. The mean preoperative AOFAS score was 52.8 ± 13.9 and increased to 87.1 ± 11.1 postoperatively at the mean follow-up of 33.8 ± 14.0 months (P = .0001). A total of 84.4% of patients had good to excellent clinical scores. Clinical scores had no significant relation with age, lesion size, depth, or body mass index. The mean MOCART score was 64.2 ± 12.0. There was no significant correlation between the total MOCART and AOFAS scores (P = .123). A significant relation was found between the defect filling (the subgroup of the MOCART score) and the clinical outcomes (P = .0001, rho = 0.731). CONCLUSIONS: The arthroscopic scaffold implantation technique is a single-step, safe, and effective method for the treatment of talar osteochondral lesions with satisfactory clinical and radiological outcomes.

RESUMEN

Arthroscopic techniques have recently gained popularity for the treatment of osteochondral defects of the talus. The microfracture procedure is the most commonly applied arthroscopic technique. However, it is not effective for the treatment of larger lesions. Tissue-engineered scaffolds have been used for cartilage regeneration arthroscopically, and promising results have been reported. We treated larger osteochondral lesions of the talus with polyglycolic acid-hyaluronan scaffold biomaterial (Chondrotissue, BioTissue AG, Zurich, Switzerland) in a single-step arthroscopic surgery. Traction methods and fibrin glue were avoided.

RESUMEN

Developmental dysplasia of the hip (DDH) is a wide-spectrum disease with a multifactorial etiology and, despite its prevalence, no definitive etiology has yet been established. The aim of this study was to investigate new risk factors for DDH by evaluating newly defined potential risk factors. A total of 71 infants were separated into 2 groups:Group I, 28 female first-born infants diagnosed with DDH and their mothers;and Group II, 43 healthy female first-born infants and their mothers. The maternal height and weight before pregnancy, infant height and weight at birth, and body mass index (BMI) of both mother and infant were determined. Calculations were made of the ratios between these parameters. Of the examined risk factors, only maternal height and the ratio of maternal height to infant BMI (MH/I-BMI) were found to be significant for DDH in infants. In conclusion, the results of this study show that a short maternal height and a low MH/I-BMI increase the risk of DDH. Further studies with a larger series are necessary to confirm these results.

RESUMEN

AIM: To evaluate the efficacy of early duloxetine therapy in stress urinary incontinence occurring after radical prostatectomy (RP). MATERIAL AND METHOD: Patients that had RP were randomly divided into 2 groups following the removal of the urinary catheter. Group A patients (n = 28) had pelvic floor exercise and duloxetine therapy. Group B patients (n = 30) had only pelvic floor exercise. The incontinence status of the patients and number of pads were recorded and 1-hour pad test and Turkish validation of International Consultation on Incontinence Questionnaire-Short Form test were applied to the patients at the follow-up. RESULTS: When the dry state of the patients was evaluated, 5, 17, 3, and 2 of 28 Group A patients stated that they were completely dry in the 3rd, 6th, 9th and 12th month respectively and pad use was stopped. There was no continence in 30 Group B in the first 3 months. Twelve, 6, and 8 patients stated that they were completely dry in the 6th, 9th and 12th month, respectively. But 3 of 4 patients in whom dryness could not be provided were using a mean of 7.6 pads in the first day and a mean of 1.3 pads after 1 year. When pad use of the patients was evaluated, the mean monthly number of pad use was determined to be 6.2 (4-8) in the initial evaluation, 2.7 (0-5) in the in 3rd month, 2 (0-3) in the 6th month and 1.6 (0-2) pad/d in the 9th month in the group taking medicine. The mean monthly number of pads used was determined to be 5.8 (4-8) in the initial evaluation, 4.3 (3-8) in the 3rd month, 3 (0-6) in the 6th month and 1.6 (0-6) pad/d in the 9th month in the group not taking medicine. CONCLUSION: According to the results, early duloxetine therapy in stress urinary incontinence that occurred after RP provided early continence.

RESUMEN

INTRODUCTION: Sex crimes remain an important problem all over the world. Very few studies about sexual offenses in Turkey have been published. Sexual assault is a serious social problem that constitutes serious health conditions affecting the lives of involved individuals. In this study, we aimed to investigate socio-demographic features of victims, assailant-victim relationships and sexual assault findings. MATERIAL AND METHODS: A total of 324 sexual assault victims presenting to and examined in the Department of Forensic Medicine, Kahramanmaras Sutcu Imam University Medical Faculty, between January 2007 and December 2010 were included in the study. The victims completed a survey at face to face interviews. RESULTS: Of 324 victims, 268 (82.7%) were female and 56 (17.3%) were male. The mean age of the victims was 16.78 ± 7.16 years. In all cases, types of the assaults were as following; vaginal penetration in 160 (49.4%), anal penetration in 117 (36.1%), oral penetration with penis in 7 (2.2%) and in the form of kissing, fondling, touching the sex organ and rubbing the sex organ in 60 (18.5%) cases. Of all the assaults, 149 (46%) were found to take place in the assailants' homes and 49 (15.1%) in the victims' homes. Of 139 cases, 85 (26.3%) had genital injury alone and 54 (16.7%) had anal injury. CONCLUSION: On the contrary to the previous studies, this study revealed that sexual assaults occurred mostly in the assailants' homes and that the incidence of anal trauma was higher.

RESUMEN

BACKGROUND/AIMS: To evaluate tumor invasion (T staging) and lymph node metastasis (N staging) of colorectal cancer preoperatively by using multi-detector computerized tomography (MDCT) and to compare with the histopathological findings. METHODOLOGY: MDCT scan was performed for 73 patients with pathological proven colorectal carcinoma. One radiologist prospectively evaluated the depth of tumor invasion (T staging) and regional lymph node involvement (N staging). The MDCT assessment was then compared with the histopathological findings for accuracy, sensitivity and specificity. RESULTS: In this study, the best accuracy results had been acquired for T1 and T2 tumors as 90.4% and 73.9%, respectively. For both histopathologically staged N0 and N1 patients, the accuracy results were 61.6%. The distant metastases were not detected in this study. CONCLUSIONS: Our study results showed that the MDCT may be useful in the preoperative assessment for the T and N staging in colorectal carcinoma.

RESUMEN

PURPOSE: Aging in men is characterized by a moderate decrease in plasma testosterone (T) levels. However, the association between partial androgen deficiency of the aging male and clinical symptoms and the ideal screening test are controversial. In this study, we investigated the association between the androgen levels and erectile function, cognitive functions and hypogonadism symptoms in aging males. MATERIALS AND METHODS: We investigated the association between total (TT), calculated free (FT) and bioavailable (BT) testosterone, and various clinical and laboratory parameters in 103 healthy males, 50-80 years old. Biochemical assessment was done after overnight fasting. Questionnaires were used to test for hypogonadism symptoms, erectile and cognitive functions. RESULTS: TT levels were not correlated with aging in this study. However, FT and BT were found to decrease with age due to rising sex hormone binding globulin. TT levels were strongly correlated with FT and BT levels (respectively p = 0.0001, p = 0.0001). TT, FT and BT were only correlated with cognitive functions (p = 0.012, p = 0.004, p = 0.02 respectively). There was no correlation between TT, FT and BT levels and erectile function and hypogonadism symptoms. CONCLUSION: T values in our study sample did not correlate with clinical signs and symptoms of hypogonadism. Thus, according to our data, symptoms in the aging male should not be indiscriminately assigned to a decrease in TT, FT or BT levels.

RESUMEN

OBJECTIVE: To investigate the effects of alpha receptor blockers used in the treatment of benign prostatic hyperplasia (BPH) on endothelial functions, coagulation parameters, and arterial blood pressure. MATERIALS AND METHODS: One-hundred fifteen patients admitted to the treatment protocol because of symptomatic BPH were included in this prospective study. Patients were given the following treatments: doxazosin 4 mg/d (n = 25), terazosin 5 mg/d (n = 26), alfuzosin 10 mg/d (n = 26), tamsulosin 0.4 mg/d (n = 21), and observation (n = 17). All cases were evaluated before treatment and in the 12th week of treatment, according to biochemical parameters, endothelial functions, and arterial blood pressure. Biochemical parameters were bleeding time, coagulation time, prothrombin time, activated partial thromboplastin time, total prostate-specific antigen (PSA), and free PSA. Endothelial functions were evaluated with ultrasonography of the brachial artery. RESULTS: When coagulation tests were evaluated, there were significant increases in bleeding and coagulation times in the groups using doxazosin and terazosin. Doxazosin and terazosin lowered arterial blood pressure significantly compared with other treatments. With regard to effects on endothelial function, there were significant differences in flow-mediated dilation rates of the brachial artery at 60 and 90 seconds before and during treatment in the alfuzosin and terazosin groups. CONCLUSIONS: Alpha receptor blockers can decrease the risk of cardiovascular complications by both reducing platelet aggregation and protecting endothelial functions in patients with prostatic hyperplasia. The only drug with a favorable effect in all 4 areas of interest, including BPH symptoms, blood pressure, platelet aggregation, and endothelial functions, was terazosin.
