Effect of Preputial Type on Bacterial Colonization and Wound Healing in Boys Undergoing Circumcision

Purpose In this study, we evaluated the effect of preputial type on bacterial colonization and wound healing in boys undergoing circumcision. Materials and Methods This study consisted of 78 boys consecutively admitted to our clinic for circumcision between 2009 and 2011. Preputial status was classified into five types on the basis of preputial retractability. One sterile culture swab was swept circumferentially once around the surface of the glans starting just proximal to the urethral meatus. Three weeks following circumcision, control swabs from the same regions of the same patients were taken and inoculated. Thus, the same patients formed the control group. Patients were evaluated on days 1 and 7 after the operation to assess whether the preputial type affected healing. Results The mean age of the children was 46.3 months. In our study, the growth rate was 71.8% in pre-circumcision patients, whereas the rate was 10.25% in the post-circumcision group. Types 1, 2, 3, 4, and 5 had 100%, 93.8%, 71.4%, 44.4%, and 53.6% colonization, respectively. A significant difference was observed among these types in terms of colonization. The most common agent was Enterococcus species (33%). When postoperative patients were evaluated, all had local swelling and hyperemia on postoperative day 1, whereas there was a significant difference on day 7. Conclusions There was a significant correlation between preputial type and bacterial colonization, and the preputial type affected post-circumcision wound healing. Practitioners should keep in mind that the healing period will be longer in patients with type 1, 2, and 3 preputium.

Factors determining biochemical recurrence in low-risk prostate cancer patients who underwent radical prostatectomy.

OBJECTIVE This study was conducted to research the factors determining biochemical recurrence (BCR) in low-risk localized prostate cancer patients who underwent radical prostatectomy (RP). MATERIALS AND METHODS We retrospectively analyzed the data of 504 patients who had undergone RP between 2003 and 2013 at our clinic. One hundred and fifty-two patients who underwent RP for low-risk prostate cancer were included in the study. RESULTS The mean follow-up period for patients was 58.7 (21-229) months. The mean age of the patients was 63.7±7.2 years (49-79). The mean prostate specific antigen (PSA) value was 5.25±4.22 ng/mL (3.58-9.45). The BCR rate after the operation was 25% (38/152). In the univariate analysis, recurrence determining factors were shown to include extracapsular involvement (ECI) (p=0.004), capsular invasion (CI) (p=0.001), age (p=0.014), and tumor size (p=0.006). However, only CI was found to be significant in multivariate analysis (p=0.001). CONCLUSION Capsular invasion is an independent risk factor in low-risk prostate cancer patients who underwent RP for BCR.

[Investigation of prevalance and risk factors for hospital-acquired urinary tract infections in patients with severe burn injury].

BACKGROUND This study aimed to investigate the prevalence and risk factors for hospital-acquired urinary tract infections in patients with severe burn injuries. METHODS In this study, patients treated due to their burn injuries of greater than 20% between August 2009 and April 2012 in Bozyaka Training and Research Hospital Burn Center were assessed retrospectively. Sixty nine patients (30 [43.5%] males, 39 [56.5%] females; mean age 40.1±16.7 years) were included into the study. RESULTS DM, duration of the catheter and catheter care showed a statistically significant correlation with hospital-acquired urinary tract infections (p<0.005). DISCUSSION A large number of hospital-acquired urinary tract infections are associated with urinary catheterization. In addition, removing urinary catheter within the shortest time possible is another issue to be considered for the prevention of these infections. If the catheter has to remain for a longer time, regular catheter care is recommended.
