Non-infected penile prosthesis cultures during revision surgery; comparison between antibiotic coated and non - coated devices

ABSTRACT Introduction: Aim of this study is to investigate bacterial growth on non-infected devices and compare antibiotic-coated and non-coated implants. Materials and methods: The charts of 71 patients who underwent revision surgeries for penile prosthesis between 1995 and 2013 were reviewed. Of those, 31 devices were antibiotic-coated prostheses, while 40 of the implants were non-coated. Swab cultures were routinely obtained from corporal, pump or reservoir site during the operation. If a bacterial biofilm was determined on the prosthesis, it was also cultured. Results: A total of 5 different organisms were cultured from 18 patients. Of them, 4 devices were antibiotic-coated and the other 14 were non-coated devices. Staphylococcus epidermidis was the most common organism, while Staphylococcus hominis, beta hemolitic streptococcus, Escherichia coli and Proteus mirabilis were also cultured. All patients who had positive cultures were treated with appropriate antibiotics for four weeks postoperatively. Median follow-up time was 41 months, ranging between 8 and 82 months. One prosthesis (non-coated) became clinically infected in the follow-up period with a totally different organism. Culture positivity rates of antibiotic-coated and non-coated devices were 13% and 35% respectively and the result was significant (p=0.00254). Conclusions: Positive bacterial cultures are present on non-infected penile prostheses at revision surgeries in some of the patients. Antibiotic coated prostheses have much less positive cultures than non-coated devices.

The level of knowledge and awareness about prostate cancer in the Turkish male and the relevant effective factors.

OBJECTIVE: Our aim was to determine the general knowledge and awareness levels, information sources, and the state of medical check-up for prostate cancer (PCa) and relevant effective factors. MATERIAL AND METHODS: The participants were asked to answer to 14 questions of a questionnaire about age, education, economic and social condition, knowledge about PCa, state of being examined and their related factors. According to demographic characteristics of the participants, levels of awareness about PCa, sources of information, affecting factors and their interrelationships were examined. Two groups were formed according to age (<60 years, >60 years) and variations according to ages were investigated. RESULTS: Two hundred and ninety-three men with an average age of 57 years (range 40-85) were included in the study. Our findings showed that 68.3% of the participants were thinking that PCa is a frequently seen disease, 88.4% were thinking that it can be treated and 62.8% of men specified that their information sources are doctors. We also found that 60.8% of the participants had not undergone prostate examination and prostate specific antigen (PSA) control. The most reason for not having annual examinations was (44.4%) "negligence". Significantly greater number of men with higher education (high school/university) were highly informed about PCa (p=0.037). Check-up rates were statistically significantly higher among men with intermediate income (p=0.041). Curability of PCa diagnosed at an early stage was acknowledged by statistically higher number of individuals under the age 60 (p<0.05). Health control, prostate examination and/or PSA control rates were higher in men with a family history of PCa and in the group of >60 years. CONCLUSION: Although PCa has a high prevalence and mortality rates, personal and social information and sensitivity levels must be increased as it can be treated if diagnosed at an early stage. We think that social and medical impact of the disease can be decreased with the planning of effective methods based on sociocultural and economic factors.

Paratesticular Fibrous Pseudotumors.

Paratesticular fibrous pseudotumors (PFPs) are rare pathologies with quite wide and variable topographic-morphological features. It is difficult to distinguish PFPs from malignant masses. Treatment can be done by resection of the mass. We reported a young patient's findings about this rare pathology.

Apolipoprotein E Genotypes in Patients with Prostate Cancer.

BACKGROUND: Apolipoprotein E (ApoE) is a potential inhibitor of cell proliferation, immune regulation and modulation of cell growth and differentiation; it also has a substantial role in antioxidant activity. ApoE has a potential role in prostate cancer progression. MATERIALS AND METHODS: ApoE genotyping was performed using real-time polymerase chain reaction (RT-PCR) for blood samples from a group of patients with prostate cancer (n=68) and a control group (n=78). RESULTS: The frequency of the E3/E3 genotype was significantly higher in patients compared to controls (p=0.004). E3/E3 genotype carriers were 3.6-fold more likely to be patients than controls (odds ratio=3.67, 95% confidence interval=1.451-9.155; p=0.004). Additionally, the patients with E3/E3 genotype had significantly higher Gleason score (p=0.017), and more patients with this genotype had a Gleason score higher than 7 (p=0.007). Individuals carrying the E4 allele were significantly more common in the control group (p=0.006). The frequency of the E3/E4 genotype was found to be significantly higher in controls compared to patients (p=0.007), and patients were significantly less likely to have this genotype than controls (odds ratio=0.89, 95% confidence interval=0.833-0.967, p=0.007). Individuals carrying the E2/E3 genotype had a significantly lower Gleason score (p=0.049)-all of the patients with this genotype had a Gleason score lower than 7 (p=0.024). CONCLUSION: E3/E3 genotype may be a potential risk factor for prostate cancer and high Gleason scoring. The E4 allele maybe a risk-reducing factor for prostate cancer.

Is semirigid ureteroscopy sufficient in the treatment of proximal ureteral stones? When is combined therapy with flexible ureteroscopy needed?

The goals of this study were to examine cases of proximal ureteral stones in which semirigid or flexible ureteroscopes alone were insufficient for endoscopic treatment, requiring the combination of both. A total of 137 patients were retrospectively evaluated. Holmium laser was used as the energy source for stone fragmentation. Each operation was begun with a 6/7.5 Fr semirigid ureteroscope (URS), and continued with a 7.5 Fr flexible URS in those procedures that failed to reach the stone or push-up. Double J stents were inserted into those patients in whom the flexible URS failed. Shock wave lithotripsy (SWL) or a repeat ureteroscopy (after 2-4 weeks) was planned in those patients who were considered to be treated unsuccessfully. The demographic features of the patients, stone sizes, treatment outcomes, need for additional treatment, complications, and the results of the postoperative 1-month early follow-up were evaluated. The mean age of the patients (77 males and 60 females) was 38 ± 6.7 years old, the mean stone size was 12.3 ± 3.7 mm, and the number of patients with persistent hydronephrosis was 86 (62.8 %). A stone-free diagnosis was achieved in a total of 124 patients (90.5 %), using a semirigid URS in 80 patients and a flexible URS in 44 patients. Treatment using a flexible URS was administered in 38 patients (27.7 %) due to push-up, and in 6 patients (4.3 %) because of the failure to advance the semirigid URS into the ureter. The treatment failed in 13 patients (9.4 %) despite the use of both methods. Treatment using low-caliber semirigid ureteroscopy and a holmium laser is possible, regardless of the stone size, in female patients without hydronephrosis. However, the need for combined treatment with flexible ureteroscopy is increased in male patients with hydronephrosis.

Scrotal Lipomatosis Mimicking Varicocele: A Case Report and Review of the Literature.

Scrotal lipomatosis is a rarely seen disease with an etiology that is not fully understood. Some information suggests that this disease may be associated with infertility. It is characterized by pain-free scrotal swelling. In this study, we reported a scrotal lipomatosis case presenting due to infertility and pain-free scrotal swelling. It was operated on with the initial diagnosis of varicocele, but once fatty tissue was observed in the scrotum, the case was diagnosed as scrotal lipomatosis. Here, we present this rare case with a literature review.

The case study in the applicability of the improvements in the treatment of urinary system stone diseases in Anatolia: the last ten years with the sample of Western Black Sea region.

OBJECTIVE: The prevalence of stone diseases is high in Turkey. Thanks to the technological improvements and to the increase in the number of qualified and experienced specialists in the last thirty years, there has been an increase in the application of minimally invasive methods in the stone disease surgery. This study, with a sample survey of Western Black Sea region, aims at revealing the changes and improvements in the treatment of stone diseases in different centers in Anatolia within the last ten years. MATERIAL AND METHODS: Six centers in 4 of the provinces of the Western Black Sea Region were selected and the patients' files were retrospectively analyzed. The treatment methods that were recommended for and/or applied to the patients diagnosed with urinary stone diseases were recorded by years. The urinary stone diseases were divided into three separate groups; kidney, ureters and bladder. Treatment options were recorded into categories as open surgery, percutaneous nephrolithotripsy, retrograde intrarenal surgery, semirigid ureterorenoscopy, flexible ureterorenoscopy, and ESWL. RESULTS: A total of 26044 patients with stone diseases have been treated in the above-mentioned centers for the last 10 years. The distributions of the stone diseases in relation to their localization were as follows: - kidney stones: 9040 (34.7%), ureter stones: 15264 (58.6%), and bladder stones: 1740 (6.7%). As for the distribution of the treatment in relation to the treatment methods, it was seen that open surgery for 1032 (4%) patients, endoscopic surgery for 15038 (58%) patients, and ESWL for 9974 (38%) patients had been applied. While URS and PCNL are currently the commonly used treatment methods in the Western Black Sea Region, RIRS has begun to be used in a limited number of patients for the last 3 years. CONCLUSION: Though being a little late, the advances in endrourology offer practical applications in the Western Black Sea region as well. Although this study suggests implications for the evaluating of the periphery outcomes of the improvements in stone disease treatments, for the planning of training schemes, and for equipment planning, further research based on more data from more centers is needed to have a nation-wide perspective.

Comparison of tacrolimus with a cyclosporine microemulsion for immunosuppressive therapy in kidney transplantation.

OBJECTIVE: To compare the efficacy and side effects of a cyclosporine microemulsion and tacrolimus in immunosuppressive therapy of renal transplantation. MATERIAL AND METHODS: Between March 2003 and June 2005, the patients who had undergone kidney transplantation surgery and who were administered either basiliximab, a cyclosporine microemulsion, mycophenolate mofetil and prednisolone or basiliximab, tacrolimus, mycophenolate mofetil and prednisolone for baseline immunosuppressive therapy were recruited to our study. We evaluated the results of an 18-month follow-up period. The donors were called back weekly for a follow-up in the first month, fortnightly in the second month and then monthly for 18 months after discharge. A total of 41 patients were included in the study. The patients were evaluated as for demographic characteristics, acute rejection, cardiovascular and metabolic side effects, graft function, infections, hirsutism, gingival hyperplasia, cosmetic side effects, nephrotoxicity, drug changes and the survival rates. RESULTS: There were no significant differences among the patients with regard to age, sex, donor type, dialysis periods, preoperative and postoperative systolic blood pressures, creatinine levels, hepatotoxicity, nephrotoxicity, occurrence of diabetes mellitus and the incidence of infection. The duration of hospitalization was prolonged in the cyclosporine A group. Acute rejection emerged in 5 patients (23.8%) in the tacrolimus group and in 4 patients (20%) in the cyclosporine A group. In the cyclosporin A group, the cholesterol and triglyceride levels were significantly higher than the tacrolimus group. The cosmetic side effects (gingival hyperplasia and hirsutism) as a reason for a change in medication were only observed in the cyclosporin A group, not in the tacrolimus group. A medication change was made in 8 patients in the cyclosporine A group and in 1 patient in the tacrolimus group. No death was observed in either group. Graft loss was observed in only 1 patient in the cyclosporine A group. CONCLUSION: Regarding the cosmetic side effects and hyperlipidemia, tacrolimus was found to be superior to cyclosporine A. Where hyperlipidemia is considered to be a risk factor for cardiovascular disease, tacrolimus use should be considered as a more acceptable treatment modality. However, the immunosuppressive regimen should be evaluated individually.

Optical urethrotomy using topical anesthesia.

A series of 28 patients with urethral strictures less than 2 cm length underwent 32 visual optical internal urethrotomy under local urethral anesthesia with lidocaine. The procedure was completed successfully in 26 of 28 (92.9%) patients. Among these 25 of 26 (96%) patients reported mild pain. Visual analogue scale (VAS) was used for the evaluation of pain. All the patients were followed up for at least 6 months. Visual optical internal urethrotomy is a minimal invasive and successful procedure for short (<2 cm) strictures. Visual optical internal urethrotomy under local urethral anesthesia with lidocaine is a safe, comfortable and cost-effective procedure.
