The relationship between the severity of erectile dysfunction and aortic stiffness.

Aortic stiffness increases in patients with erectile dysfunction (ED) but it is not known whether aortic stiffness affects the degree of ED. In the present study, we aimed to determine whether there is any relationship between aortic stiffness and the severity of ED. Patients with ED were divided into 3 groups according to the International Index of Erectile Function (IIEF) scores. Mild ED was named as group 1, moderate ED as group 2 and severe ED as group 3. The values of fasting blood glucose (FBG), serum lipid values, total testosterone (T. tes), and free testosterone (F tes) were recorded. Aortic stiffness was determined by pulse wave velocity (PWV) and augmentation index (AIX) measurements. The mean or median values of the laboratory parameters among the groups were similar (p > .05). No statistical difference was found between the groups in terms of AIX value (p = .386). Mean PWV values were calculated as 7.26, 8.30 and 8.78 in group 1, group 2 and group 3 respectively. PWV values were significantly different between groups (p < .0001). PWV values were found to be increased with increasing severity of erectile dysfunction.

Our intraoperative boost radiotherapy experience and applications.

OBJECTIVE: To present our experience since November 2013, and case selection criteria for intraoperative boost radiotherapy (IObRT) that significantly reduces the local recurrence rate after breast conserving surgery in patients with breast cancer. MATERIAL AND METHODS: Patients who were suitable for IObRT were identified within the group of patients who were selected for breast conserving surgery at our breast council. A MOBETRON (mobile linear accelerator for IObRT) was used for IObRt during surgery. RESULTS: Patients younger than 60 years old with <3 cm invasive ductal cancer in one focus (or two foci within 2 cm), with a histologic grade of 2-3, and a high possibility of local recurrence were admitted for IObRT application. Informed consent was obtained from all participants. Lumpectomy and sentinel lymph node biopsy was performed and advancement flaps were prepared according to the size and inclination of the conus following evaluation of tumor size and surgical margins by pathology. Distance to the thoracic wall was measured, and a radiation oncologist and radiation physicist calculated the required dose. Anesthesia was regulated with slower ventilation frequency, without causing hypoxia. The skin and incision edges were protected, the field was radiated (with 6 MeV electron beam of 10 Gy) and the incision was closed. In our cases, there were no major postoperative surgical or early radiotherapy related complications. CONCLUSION: The completion of another stage of local therapy with IObRT during surgery positively effects sequencing of other treatments like chemotherapy, hormonotherapy and radiotherapy, if required. IObRT increases disease free and overall survival, as well as quality of life in breast cancer patients.

The Time of Spontaneous Resolution of Monosymptomatic Nocturnal Enuresis (MNE) Is Familial.

PURPOSE: To investigate whether or not the age of spontaneous resolution of monosymptomatic nocturnal enuresis (MNE) was familial. PATIENTS AND METHODS: A questionnaire was administered to more than 1,500 people, and 100 appropriate participants were identified from four referral hospitals. We included the participants who had MNE and whose parents also had MNE with spontaneous resolution. Then the association between the spontaneous resolution time of MNE in parents and that in their children was investigated. RESULTS: The mean ages of spontaneous resolution were 10.7 (10-30 years), 9.4 (6-17 years) and 10.9 (6-18 years) in participants, their mothers and their fathers, respectively. According to the statistical analysis, there was a positive correlation between participants and both their mothers and fathers (p < 0.05). In addition, it was revealed that familial MNE history based on first- and second-degree relatives, in addition to their parents, was also associated with the increased spontaneous resolution age of MNE (p < 0.05). According to our results, gender and parents' education status were not statistically associated with the spontaneous resolution (p > 0.05). CONCLUSION: As a conclusion, the age of spontaneous resolution of MNE is familial. Although the exact reasons of spontaneous resolution still remain a mystery; further genetic investigations may be able to resolve this mystery.

Long-term results of breast cancer patients who received IOERT as boost during BCS: A single-institution retrospective analysis.

Objectives: Intraoperative electron radiotherapy (IOERT) applied as boost to the tumor bed during breast conserving surgery is advantageous in terms of local recurrence in breast cancer patients. In addition, it has other advantages over the adjuvant boost RT such as no risk of tumor bed change, ease of sequencing radiotherapy chemotherapy, and reduced workload of the radiotherapy clinic. This study aimed to evaluate the long-term results of our patients who were treated with this method in our institution and are still being followed up. Material and Methods: One hundred and three patients enrolled in this study received IOERT equivalent to 10 Gy as boost during BCS and were subsequently given adjuvant WBI according to the biological subtype of the tumor systemic therapy. These patients were analyzed using their files and hospital records. Patients were evaluated for overall survival, local recurrence, distant metastasis, and cosmetic outcome (using LENT-SOMA scale). Results: Median age was 53,5 (27-74), mean follow-up time was 75 (48-106) months. Mean pathological tumor size was 18 mm (4-30), 90 of the patients had invasive ductal carcinoma, eight of them were lobular and five of them had mixed histological structure. Ninety-three of the patients presented histological grade II, 15 grade III; 74 patients were luminal A-like, 15 luminal B-like, eight HER2 positive and six triple negative breast cancer. According to the LENT-SOMA scale, 35 had grade 0, 42 each had grade I, 23 had grade II, and two had grade III. All patients underwent whole breast irradiation after surgery, 81 received chemotherapy and 90 endocrine therapy. There was one local recurrence, distant recurrence was seen in four patients and one patient died of non-breast cancer causes. Overall survival was %99, and event free survival %96. Conclusion: IOERT for breast cancer treatment during BCS is a safe option with low chronic toxicity and the cosmetic outcome gets better over time.

[Comparison of the hemostatic efficiency of Ankaferd Blood Stopper and fibrin glue on a liver laceration model in rats]. / Siçanlarda karaciger laserasyon modelinde Ankaferd Blood Stopper ve fibrin yapistiricinin hemostatik etkinliginin karsilastirilmasi

BACKGROUND: Ankaferd Blood Stopper® (ABS) is an organic topical hemostatic agent that has become available in recent years. The aim of this study was to compare the effectiveness of ABS in a liver laceration model in rats with that of fibrin glue (FG), which is currently being used widely in clinics. METHODS: Thirty-two Wistar Albino type rats were randomly divided into four groups. In the Sham group (Group 1), only the liver was explored. In the other study groups (Groups 2, 3 and 4), three incisions were performed, each 1 cm long and 2 mm deep, on the front of the left lobe of the livers. In Groups 2 and 3, ABS and FG were used as hemostatic agents, respectively. No materials were used for the injuries in the Control Group (Group 4). Bleeding periods, changes in the hematocrit levels, intraabdominal adhesion levels, and histopathological effects were taken into consideration. RESULTS: There was no significant difference between the period of hemostasis in Groups 2 and 3, whereas the same period was evidently longer in Group 4 (17 (15-20) sec, 18 (16-20) sec, 70 (64-74) seconds, respectively; p<0.05). No significant difference was detected between the groups regarding intraabdominal adhesion levels (Group 1: 1 (0-1), Group 2: 2 (1-3), Group 3: 2 (1-3), Group 4: 2 (1-3); p>0.05). Microscopic evaluations revealed similar histopathological effects of ABS and FG on the liver and surrounding tissues (p>0.05). CONCLUSION: The topical hemostatic effectiveness of ABS was shown to be comparable to FG in a liver laceration model in rats. There was no significant difference between these materials regarding adhesion formation in intraabdominal use or histopathological effects.

Effects of polyurethane membrane on septic colon anastomosis and intra-abdominal adhesions.

BACKGROUND: Anastomotic leakages and adhesions after gastrointestinal tract surgery are still a significant cause of morbidity and mortality. The rate of anastomotic leakage is 3%-8%, whereas the mortality from leakage is over 30%. Intra-abdominal sepsis is a well-known cause of anastomotic leakage. In addition, intra-abdominal adhesion is a major cause of hospital admissions and reoperations and is associated with morbidity and mortality. In this study, we aimed to investigate the effects of a polyurethane membrane on anastomotic healing and intra-abdominal adhesions. METHODS: This study used 32 Wistar albino rats divided into four groups. Standard resection of left colon 2 cm above the peritoneal reflection and colonic anastomosis were performed after causing abdominal sepsis through caecal ligation and perforation. The control groups (1 and 3) received no further treatment. The experimental groups (2 and 4) received the polyurethane membrane around the colonic anastomosis. Burst pressure, hydroxyproline, interleukin-6 (IL-6), nitric oxide (NO), tissue plasminogen activator (tPA), and tumor necrosis factor-alpha (TNF-α) levels were measured, and histopathological characteristics of the anastomosis were analyzed after re-laparotomy. Moreover, adhesion scores were measured. RESULTS: No statistically significant differences were found in the mean burst pressure levels between sacrificed animals on days three and five (p=0.259, p=0.177). When all the groups were compared, no significant difference was observed in the hydroxyproline, NO, and IL-6 levels (p=0.916, p=0.429, p=0.793, p=0.332, p=0.400, p=0.317). However, in groups 2 and 4, the tPA levels were significantly increased by Opsite therapy (p=0.001, p=0.003), and a statistically significant difference was observed in the adhesion scores (p<0.035). Groups 2 and 4 had significantly lower adhesion scores than groups 1 and 3. CONCLUSION: We found that Opsite therapy had no positive or negative effects on histopathological and biochemical healing in the experimental septic colon anastomosis model. However, the perianastomotic application of polyurethane membrane effectively decreased the intra-abdominal adhesions.

Relationship between Response to PDE5 Inhibitors and Penile Duplex Doppler Ultrasound in Erectile Dysfunction.

The relationship between the results of penile duplex Doppler ultrasound (PDDU) and response to vardenafil was investigated in patients diagnosed with erectile dysfunction (ED). Data from 148 patients with ED were analyzed retrospectively. Patients who did not respond to therapy were classified in to Group I (n = 32), those who responded partially were classified into Group II (n = 40), and complete responders were classified into Group III (n = 76). Age, comorbidities, and vascular and penile pathologies were compared among the three groups. While diabetes mellitus (DM) and dyslipidemia positivity adversely affected the response to treatment, the presence of hypertension (HT), Peyronie's disease and priapism increased the therapeutic response to the treatment (p < 0.05). Arterial insufficiency was present in 20 (30.3%), 25 (37.9%) and 21 (31.8%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). Venous insufficiency was observed in three (14.3%) patients in Group I and in eight (85.7%) patients in Group III (p = 0.001). Arterial/venous insufficiency was seen in 9 (30%), 14 (46.7%) and 7 (23.3%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). The response rate to treatment was highest in normal patients according to PDDU, followed by patients with venous insufficiency. In addition, it was found that DM decreased the response to treatment, whereas the response increased in cases with HT, priapism and Peyronie's disease.

The effect of inhaling thinner and/or cigarette smoke on rat kidneys.

Although the effects of cigarette smoking and/or thinner inhalation on various organs have been investigated, there isn't enough study available in literature about their effects on kidneys. Therefore, in this study we investigated the effect of smoking and/or inhalation on the rat kidney. In this study, stand-alone inhalation of thinner and cigarette smoke and their application together were used to determine histopathologic changes, primarily the influences on rat kidneys. The study included 60 Wistar Albino species male rats. The 60 rats were divided into 4 groups of 15 rats each. Of the groups, three were working groups and the fourth was the control group. The rats in the first study group inhaled thinner only (T), those in the second group cigarette smoke only (CS), and the rats in the third group were made to inhale both thinner and cigarette smoke (TC). Each study group was divided into 3 subgroups each comprising 5 rats and inhalation was continued for periods of 2 wk, 4 wk, and 6 wk. Thinner was vaporized into the cage with a millipore pump at a constant pressure twice per day for 1 h for 5 days (toluene 2800-3000 ppm, acetone 500-600 ppm, isobutyl acetate 7000-8000 ppm, and isobutanol 6000-7000 ppm). Cigarette smoke was given 4 times per day for 15 min each, using a mechanism prepared with an aquarium motor (containing 1.2 mg nicotine,13 mg tar, and 13 mg carbonmonoxide; 60 puffs/min). After that, rat kidneys were removed. The kidneys were weighed and were given macroscopic and microscopic examination. There were significant differences for the thinner and thinner + cigarette smoke groups in comparison to the control group, observed in both proximal and distal tubules. However, changes in the cigarette smoke group were only in proximal tubules and were smaller in extent. Thinner has been widely used as a industrial substance. Thinner usage is an important health problem. Those sniffing thinner generally also use cigarettes. The findings of the present study reemphasize the importance of taking immediate measures in order to prevent thinner inhaling among homeless children, who pose an important social problem, and to protect people who work in industrial branches that widely use thinner.

Comparison effects of different doping on spin-Peierls transition in CuGeO(3).

The comparison between non-magnetic spin-Peierls (SP) and magnetic Néel ground states have been investigated in CuGeO(3) doped with Zn(2+), Ni(2+) and Mn(2+) ions by using the electron spin resonance (ESR) techniques in the temperature range of 3-300 K. It was concluded that the one-dimensional (1D) antiferromagnetic (AF) spin chain formed of spin-1/2 (Cu(2+)) ions is broken by spin-0 (Zn(2+)), spin-1 (Ni(2+)), and spin-5/2 (Mn(2+)) ions, giving uncoupled spins at the end of the chains that give extra contribution to the spectra at lower temperature. An almost linearly dependence of frequency of resonance field has been showed for X-, K- and Q-band spectra. By the analysis of resonance field-frequency relations, the effects of the internal field is refined and thus the spectroscopic g-factor and internal field were calculated to be g=1.9386 and H(i)=148 G, respectively.

Comparison of response to treatment of unilateral and bilateral varicocelectomy.

BACKGROUND/AIM: We aimed to compare the results of unilateral and bilateral varicocele surgery. MATERIALS AND METHODS: In two referral hospitals, the data of 180 patients who were treated with unilateral and bilateral microscopic varicocelectomy were retrospectively analyzed. Sperm parameters and spontaneous pregnancy rates were compared in patients who underwent bilateral and unilateral microscopic varicocelectomy. RESULTS: The mean age was 29.6 (17-46) years. While 82 patients underwent unilateral varicocelectomy (Group I), 98 patients underwent bilaterally varicocelectomy (Group II). Forty (48.8%) spontaneous pregnancies occurred in Group I and 59 (60.2%) in Group II. When we analyzed sperm parameters, the rate of increase in the number of sperm in spermiograms was 17% in Group I and 27.5% in Group II. The rate of increase in sperm mobility was 58.5% and 50% in Group I and II, respectively. The improvement rate in sperm morphology was 46.3% in Group I and 56.1% in Group II. There were no significant differences between all these parameters. CONCLUSION: In light of our results, although pregnancy rates seemed to be higher in patients who underwent bilateral varicocelectomy, these results were not statistically significant. Improvement rates in sperm parameters were similar between the patients who underwent unilateral and bilateral varicocelectomy.

Categorization of ureteroscopy complications and investigation of associated factors by using the modified Clavien classification system.

BACKGROUND/AIM: The purpose of the present study was to review the complications of ureteroscopy (URS) by using the modified Clavien classification system (MCCS) and to investigate the factors associated with complications. MATERIALS AND METHODS: Data regarding 811 patients who underwent URS for ureteral calculus were analyzed. Peroperative and postoperative complications were recorded. The patients were divided into seven groups depending on the severity of the complications. The association of sex, stone size, number, and localization with each MCCS grade was also evaluated. RESULTS: The average age was 45 years. The success of the procedure after one session was 93.5%. Complications were recorded in 57.9% of the patients. According to the MCCS, grade I, II, IIIa, IIIb, IVa, IVb, and V complications were documented in 29.8%, 7.1%, 8.6%, 11%, 0%, 1.2%, and 0% of the patients, respectively. The factors associated with the complications graded by MCCS were sex, stone size, number of stones, and localization. In addition, in multivariate analysis, history of previous surgeries for urolithiasis, orifice dilatation, and instrument size were associated with complications. CONCLUSION: According to MCCS, sex, history of previous surgeries for urolithiasis, orifice dilatation, size of the instrument, stone size, number of stones, and localization are associated with different grades of complications in URS.

Adenosine deaminase and xanthine oxidase activities in bladder washing fluid from patients with bladder cancer: a preliminary study.

Activities of adenosine deaminase (AD), and xanthine oxidase (XO) enzymes were measured in bladder washing fluid (BWF) from 37 patients with bladder cancer. The patients were divided into several groups according to their sex; pattern, number, and depth of the tumors; and tumor grade. There was a statistically significant difference in XO activities between the patients having no tumor and papillary tumor (p < 0.002). The differences in XO values between the patients having no tumor and single tumor; and with no tumor and multiple tumors were statistically significant (p < 0.012, p < 0.016 respectively). XO activities were increased in patients with both papillary and multiple tumors compared to tumor-free group. Regarding to the depth of tumors, only the differences in XO values between the patients having no tumor and superficial tumor was statistically significant (p < 0.037). XO values of patients in grade1 were higher than the patients having no tumor (p < 0.010). AD activities in patients with multiple and invasive tumor were increased compared to patients with single and superficial tumor. AD values in grade 3 were lower than grade 2. However, we did not find any statistically significant differences in AD activities in all groups. As a conclusion, increased XO activity in BWF might be a potentially important finding as an additional diagnostic biochemical tool for bladder cancer. But we could not say this for AD activity. Further investigations in a larger cohort of patients with bladder cancer are needed to enlighten the possible diagnostic role of XO and AD in BWF.

Gamma Probe Guided Minimally Invasive Parathyroidectomy without Quick Parathyroid Hormone Measurement in the Cases of Solitary Parathyroid Adenomas.

OBJECTIVE: In this study, our aim was to study the efficiency of gamma probe guided minimally invasive parathyroidectomy (GP-MIP), conducted without the intra-operative quick parathyroid hormone (QPTH) measurement in the cases of solitary parathyroid adenomas (SPA) detected with USG and dual phase 99mTc-MIBI parathyroid scintigraphy (PS) in the preoperative period. MATERIAL AND METHODS: This clinical study was performed in 31 SPA patients (27 female, 4 male; mean age 51±11years) between February 2006 and January 2009. All patients were operated within 30 days after the detection of the SPA with dual phase 99mTc-MIBI PS and USG. The GP-MIP was done 90-120 min after the iv injection of 740 MBq 99mTc-MIBI. In all cases, except 1 patient, the GP-MIP was performed under local anesthesia; due to the enormity of size of SPA, then general anesthesia is chosen. RESULTS: The operation time was 30-60 min, mean 38,2±7 min. In the first postoperative day, there was a more than 50% decrease in PTH levels in all patients and all but one had normal serum calcium levels. Transient hypocalcemia was detected in one patient. CONCLUSION: GP-MIP without intra-operative QPTH measurement is a suitable method in the surgical treatment of SPA detected by dual phase 99mTc-MIBI PS and USG. CONFLICT OF INTEREST: None declared.

Adrenomedulline improves ischemic left colonic anastomotic healing in an experimental rodent model.

BACKGROUND: Leakage from colonic anastomosis is a major complication causing increased mortality and morbidity. Ischemia is a well-known cause of this event. This study was designed to investigate the effects of adrenomedullin on the healing of ischemic colon anastomosis in a rat model. METHODS: Standardized left colon resection 3 cm above the peritoneal reflection and colonic anastomosis were performed in 40 Wistar rats that were divided into four groups. To mimic ischemia, the mesocolon was ligated 2 cm from either side of the anastomosis in all of the groups. The control groups (1 and 2) received no further treatment. The experimental groups (3 and 4) received adrenomedullin treatment. Adrenomedullin therapy was started in the perioperative period in group 3 and 4 rats (the therapeutic groups). Group 1 and group 3 rats were sacrificed on postoperative day 3. Group 2 and group 4 rats were sacrificed on postoperative day 7. After careful relaparotomy, bursting pressure, hydroxyproline, malondialdehyde, interleukin 6, nitric oxide, vascular endothelial growth factor, and tumor necrosis factor alpha levels were measured. Histopathological characteristics of the anastomosis were analyzed. RESULTS: The group 3 animals had a significantly higher bursting pressure than group 1 (p<0.05). Hydroxyproline levels in group 1 were significantly lower than in group 3 (p<0.05). The mean bursting pressure was significantly different between group 2 and group 4 (p<0.05). Hydroxyproline levels in groups 3 and 4 were significantly increased by adrenomedullin therapy relative to the control groups (p<0.05). When all groups were compared, malondialdehyde and nitric oxide were significantly lower in the control groups (p<0.05). When vascular endothelial growth factor levels were compared, no statistically significant difference between groups was observed. Interleukin 6 and tumor necrosis factor alpha were significantly decreased by adrenomedullin therapy (p<0.05). The healing parameters and inflammatory changes (e.g., granulocytic cell infiltration, necrosis, and exudate) were significantly different among all groups (p<0.05). CONCLUSION: Adrenomedullin had positive effects on histopathologic anastomotic healing in this experimental model of ischemic colon anastomosis.

Tc-99m radio-guided completion thyroidectomy for differentiated thyroid carcinoma.

BACKGROUND: The purpose of this study is to investigate whether or not radio-guided surgery has any beneficial effects on completion thyroidectomy (CT) and the associated complication rates. PATIENTS AND METHODS: Twenty-seven patients were scheduled for CT, for thyroid carcinoma, from December 2004 to June 2005, and were included in the study. All the patients had had initial thyroid surgery in other centers and been referred to our clinic for CT. Operation findings and the effectiveness of Tc-99m radio-guided CT were analyzed. RESULTS: The intraoperative mean ratio of thyroid activity to background activity counted with a gamma probe was 1.3 ± 0.3. Average operation timing was 74 ± 9 minutes. Postoperatively, no residual tissue was detected in any of the patients with ultrasonography and thyroid scintigraphy. In the first postoperative month, serum TSH level was 61 ± 16.4 mIU / L, when preoperatively it was 7.3 ± 3.1 mIU / L (P < 0.001). In the postoperative period, one patient experienced temporary hypoparathyroidism (3.9%). Permanent hypoparathyroidism or recurrent laryngeal nerve damage was not detected in any patient. CONCLUSION: Tc-99 radio-guided CT is a reliable surgical method, which provides the detection and removal of residual thyroid tissues with minimal complications.

Comparison of the concentration of trace metals (Ni, Zn, Co, Cu and Se), Fe, vitamins A, C and E, and lipid peroxidation in patients with prostate cancer.

The anticarcinogenic and antioxidant properties of vitamins A, C, E and pro- or antioxidant properties of trace metals have recently attracted increased attention. We examined the levels of antioxidant vitamins (A, C and E), selenium and malondialdehyde (MDA), and trace metals (Fe, Ni, Zn, Co and Cu) in patients with prostate cancer. In total, 41 subjects (21 controls and 20 prostate cancer patients) were included in the study. The levels of trace elements and Fe in whole blood were determined by atomic absorption spectrophotometry. Serum levels of Se were determined using a fluorimetric method, while a HPLC method was used for serum levels of vitamins and MDA. The levels of vitamins A and E were significantly lower and MDA levels were significantly higher (p<0.001) in patients with prostate cancer compared to controls. Serum vitamin C was significantly lower in patients with prostate cancer when compared to controls (p<0.01). Moreover, Se and Zn levels were also significantly lower, and levels of Ni, Co, and Cu were higher (p<0.001) in patients with prostate cancer than in controls. Fe levels were not significantly different in patients compared to controls (p>0.05). Our findings, together with the results of previous animal studies, suggest that the administration of vitamins A, C, and E, and Se and Zn may be beneficial in the prevention and treatment of human prostate cancer.
