Comparative Analysis of Preoperative Ratio Based Markers in Predicting Postoperative Infectious Complications After Gastrectomy.

AIM: Postoperative infections (POIs) are associated with prolonged postoperative recovery, delayed adjuvant therapy, psychological problems, and poor long-term outcomes. The study aims to cross-compare the ratio-based preoperative parameters to predict POIs in patients with D2 gastrectomy for gastric cancer. MATERIALS AND METHODS: A retrospective cohort and single-center study evaluated the data of 293 patients who underwent curative gastrectomy between January 2007 and November 2019 in a tertiary hospital in Istanbul. A receiver operating characteristic (ROC) curve was used to assess the ability of laboratory values to predict clinically relevant POIs. The predictive capacity of the neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR), and CRP-albumin ratio (CAR) was calculated by the area under the curve. Then, the cutoff points were determined for all 4 indexes. RESULTS: POIs developed in 77 (26.2%) patients. Patients with POI had higher Charlson comorbidity index (CCI) scores and a longer length of hospital stay. ROC curve analysis revealed that NLR, LMR, and CAR were significantly effective in predicting POI, while PLR was ineffective. LMR was the best ability to predict the POI. According to multivariate analysis, CCI score 3, NLR> 3.8, and LMR 2.34 were independent risk factors influencing the POI. CONCLUSION: Preoperative LMR was most predictive for POI. Although CAR predicted the development of the POI, it was not superior to LMR and NLR. PLR did not have any prediction for POI. In addition, increased comorbidity (CCI 3) was an independent risk factor for POI.

Epididymoorchitis due to Brucella melitensis: review of 19 patients.

INTRODUCTION: We describe the clinical characteristics, treatment and long-term outcome of 19 patients with Brucella epididymoorchitis treated at the Department of Urology. MATERIALS AND METHODS: Between 1998 and 2005, a total of 19 cases with epididymoorchitis due to Brucella melitensis were diagnosed at our hospital. The diagnosis of Brucella was made by isolating Brucella species from blood culture or epididymal aspiration or by standard tube agglutination testing and slide agglutination testing together with clinical findings. RESULTS: Seven cases (36.8%) had undulant fever. Brucella species was isolated from blood cultures in 11 patients and from epididymal aspiration in 3 patients. Rose Bengal tests were positive in all patients. Total recovery was obtained in 12 cases with a 6-week treatment. Five patients (26.3%) did not respond to therapy and another 2 (10.5%) relapsed. CONCLUSIONS: Brucella orchitis should be considered in the differential diagnosis of scrotal pathologies where Brucella is endemic.

Assessment of surface water quality using multivariate statistical techniques: a case study of Behrimaz Stream, Turkey.

Multivariate statistical techniques, such as cluster analysis (CA), principal component analysis, and factor analysis, were applied for the evaluation of temporal/spatial variations and for the interpretation of a water quality data set of the Behrimaz Stream, obtained during 1 year of monitoring of 20 parameters at four different sites. Hierarchical CA grouped 12 months into two periods (the first and second periods) and classified four monitoring sites into two groups (group A and group B), i.e., relatively less polluted (LP) and medium polluted (MP) sites, based on similarities of water quality characteristics. Factor analysis/principal component analysis, applied to the data sets of the two different groups obtained from cluster analysis, resulted in five latent factors amounting to 88.32% and 88.93% of the total variance in water quality data sets of LP and MP areas, respectively. Varifactors obtained from factor analysis indicate that the parameters responsible for water quality variations are mainly related to discharge, temperature, and soluble minerals (natural) and nutrients (nonpoint sources: agricultural activities) in relatively less polluted areas; and organic pollution (point source: domestic wastewater) and nutrients (nonpoint sources: agricultural activities and surface runoff from villages) in medium polluted areas in the basin. Thus, this study illustrates the utility of multivariate statistical techniques for analysis and interpretation of data sets and, in water quality assessment, identification of pollution sources/factors and understanding temporal/spatial variations in water quality for effective stream water quality management.

Sertoli cell tumor of the testis: a case with late metastasis.

We report on a 20-year-old male who underwent a radical orchidectomy when he was 12 years old which revealed a Sertoli cell tumor in his right testis, and who presented with a 5 x 3 cm retroperitoneal metastatic mass 8 years after orchidectomy. Current experience on Sertoli cell tumor of the testis (SCTT) is insufficient to prognosticate the clinical behavior of the primary tumor on the long term. Case reports in the literature on patients with late metastases suggest a very long followup after orchidectomy may be required.

The effect of male circumcision on pudendal evoked potentials and sexual satisfaction.

Circumcision is generally considered a simple, rapid operation with medical benefits which accrue throughout life. The influence of circumcision on sexual satisfaction has always been argued. In this study, the assessment of the pudendal evoked potentials (PEP) in adults before and at least 12 weeks after circumcision was done. Healthy males aged between 18-27 years, who were willing to undergo circumcision were included in the study. Before and after circumcision, sexual performance was evaluated with the Brief Male Sexual Function Inventory (BMSFI), consisting of sexual drive, erection, ejaculation, problem assessment, and overall satisfaction sections. Forty-three adult males were enrolled in the study. Mean PEP latency was 41.97 +/- 0.25 (39.90-44.50) ms and 44.73 +/- 0.33 (40.90-47.60) ms before and after circumcision, respectively. Mean difference between pre- and postoperative PEP values was 2.76 ms which was statistically significant (p < 0.001). Mean ejaculatory latency time was significantly longer after circumcision (p < 0.001). In the light of our findings, we conclude that circumcision may contribute to sexual satisfaction by prolonging PEP latency but further studies are warranted also regarding the other dimensions of circumcision.

Repairing urethrocutaneous fistula in adults: is a catheter necessary?

OBJECTIVES: To demonstrate that urethrocutaneous fistulas can be repaired under local anesthesia in adult patients without catheters. METHODS: From 1998 to 2006, 96 patients with urethrocutaneous fistulas underwent repair under local anesthesia. The patients were divided into two groups in terms of whether they did or did not have a catheter placed. The catheterized group included 45 patients and the uncatheterized group included 51 patients. The uncatheterized patients were discharged on the operation day, and the catheterized patients were discharged 1 to 4 days postoperatively. Patients were reevaluated on the 7th postoperative day and after 3 months in terms of wound infection, urethral stricture, and fistula recurrence. RESULTS: All patients tolerated the fistula repair well under local anesthesia. The success rate of fistula repair was 93.3% and 94.1% in the catheterized and uncatheterized groups, respectively. Wound infection was seen in 6 patients in the first group but was not noted in the uncatheterized group. Fistulas recurred in 3 patients in each group (6.6% and 5.8%) after 3 months postoperatively. CONCLUSIONS: Catheterless fistula repair with local anesthesia in adults is an effective, safe, and inexpensive procedure.

Mesh fixation devices and formation of intraperitoneal adhesions.

PURPOSE: To investigate the effect of mesh fixation devices on the formation of intra-abdominal adhesions. MATERIALS AND METHODS: Fourteen New Zealand rabbits were used. In seven animals, nickel-titanium (nitinol) anchors (group 1) and titanium tacks (group 2) were applied by laparoscopy on the right and left sides of the abdomen, respectively. In the remaining seven rabbits, the same devices were applied on prosthetic meshes (groups 3 and 4, respectively). On day 30, the rabbits were sacrificed and macroscopic adhesion scoring was performed. All the specimens were assessed by scanning electron microscopy (SEM). RESULTS: All parameters of adhesion except extension were significantly higher in group 4 than group 3 (P < 0.05). Comparisons of group 1 vs. group 2 were not statistically significant (P > 0.05). All the comparisons between a nonmesh group and a mesh group resulted in significant differences. SEM results revealed that the mesothelial cell layer and connective tissue intensively covered the tacks in group 2 whereas no similar findings were observed in group 1. Comparable appearances were encountered in groups 3 and 4. CONCLUSION: The nitinol anchor is associated with an acceptable level of adhesion formation and its intraperitoneal use can be considered safe in this regard.

Detachment of the connecting tube from the port and migration into jejunal wall.

After laparoscopic adjustable gastric banding (LAGB), early recognition and treatment of uncommon complications are important. A 36-year-old man who had undergone LAGB presented at our clinic with weight gain of 14 kg during the prior 6 months. During investigation, detachment of the connecting tube from the port and migration of this tube into the jejunal wall were found. The detached port was replaced with a new port, and laparoscopically-assisted jejunorraphy was performed.

A peripheric neuromodulation technique for curing detrusor overactivity: Stoller afferent neurostimulation.

OBJECTIVE: To perform Stoller afferent neurostimulation (SANS) with and without a low-dose anticholinergic (oxybutynin hydrochloride) in patients with detrusor overactivity and compare the results obtained with the two therapeutic approaches. MATERIAL AND METHODS: A total of 43 patients with symptoms of detrusor overactivity (frequency, urgency, urge incontinence) underwent urodynamic studies (UDS). Those in whom UDS revealed phasic detrusor overactivity were evaluated using a quality of life questionnaire and voiding diaries. Patients were randomized into two groups: Group 1 received SANS alone; Group 2 received SANS combined with a low-dose anticholinergic (5 mg of oral oxybutynin hydrochloride). Both groups were re-evaluated following 8 weeks of therapy. RESULTS: There were 21 patients in Group 1 and 22 in Group 2. The treatment response rate was 61.6% and 83.2% in Groups 1 and 2, respectively. In both groups, the best symptomatic improvements were obtained in patients with urge incontinence. The percentage decreases in the mean number of symptoms of frequency and urgency were 36.7% and 46.1%, respectively in Group 1 and 44.2% and 61.1%, respectively in Group 2. However, there were no statistically significant differences in the effects on frequency and urgency between the two groups. The anticholinergic drug was well tolerated by all patients in Group 2. One patient reported local tenderness, and a small hematoma developed in another following SANS therapy. CONCLUSION: SANS is an easy and inexpensive therapeutic method with low morbidity in patients with an overactive bladder. Combination with a low-dose anticholinergic increases the success rate without causing any significant side-effects.

Intravesical heparin and peripheral neuromodulation on interstitial cystitis.

INTRODUCTION: We wanted to evaluate the therapeutic effect of intravesical heparin and peripheral neuromodulation on patients with interstitial cystitis. MATERIALS AND METHODS: From March 2002 to August 2003, 8 female and 2 male subjects conform to the NIDDK criteria and not responsive to the previous conventional treatments were included in the study. Wisconsin pain scores, maximal cystometric capacities, and night and day voiding frequencies were determined and these studies were repeated in the 2nd and 12th months of the treatment with 10,000 units intravesical heparin and peripheral neuromodulation. Frequency of the treatment was once a week during first 8 weeks, once in 2 weeks in the following 8 weeks, and once in 3 weeks four times. Then, it was decreased to once a month. RESULTS: The mean follow-up period was 13 months (12-16 months). Day and night voiding frequency were significantly better in the 2nd and 12th months, when compared to pretreatment values. The Wisconsin pain scores were 62.5 +/- 13.9% and 62.8 +/- 15.2% in the 2nd and the 12th months, respectively. The average increase in the maximum cystometric capacity was 54.8 +/- 27.4% and 52.5 +/- 31.6% in the 2nd and the 12th months, respectively. CONCLUSIONS: Intravesical heparin and peripheral neuromodulation combination seems to be an alternative for patients with interstitial cystitis not responsive to other treatments.

Seminal plasma prostate-specific antigen level in benign prostatic hyperplasia.

INTRODUCTION: We evaluated the role of the seminal plasma PSA level in the prediction of the response to alpha-blocker treatment in patients with benign prostatic hyperplasia. MATERIALS AND METHODS: 18 male patients with lower urinary tract symptoms were enrolled in the study. After their blood was sampled for PSA, ejaculates of all the subjects were obtained. Serum and seminal plasma PSA levels were calculated by Active PSA IRMA kit. Patients were given 4 mg/day doxazosin for a period of 6 weeks, following which their International Prostate Symptom Score (IPSS) evaluation was repeated. The correlation between serum PSA, seminal plasma PSA and PSA density levels and the percentage improvement in IPSS was investigated. RESULTS: The mean serum PSA level, the mean PSA density and the mean seminal PSA level of the patients were 2.7 +/- 1.2 ng/ml, 0.05 +/- 0.02 ng/ml/cm(3) and 0.7 +/- 0.39 g/l, respectively. The percentage improvement in IPSS varied from 26.9 to 53.5%. Serum PSA and serum PSA density were not useful in the prediction of the response to alpha-blocker treatment, but the seminal PSA levels correlated with the percentage improvement in the IPSS (p = 0.017). CONCLUSIONS: Seminal plasma PSA has been found to be a better predictor of the response to alpha-blocker treatment when compared to serum PSA and PSA density.

Circumcision in adults: effect on sexual function.

OBJECTIVES: To evaluate the effects of adult circumcision on sexual function in men circumcised only for religious or cosmetic reasons. METHODS: The study group consisted of 42 male patients with a median age of 22.3 years (range 19 to 28) referred for circumcision from June 2002 to January 2003. Of the 42 men, 39 desired circumcision for religious reasons. Before circumcision, their sexual performance was evaluated using the Brief Male Sexual Function Inventory (BMSFI) and ejaculatory latency time. The BMSFI evaluation and ejaculatory latency time measurements were repeated after a postoperative interval of at least 12 weeks. The scores in the five main sections of the BMSFI and the ejaculatory latency times before and after circumcision were analyzed. RESULTS: The differences in the mean BMSFI scores were not statistically significant in any of the five sections. However, the mean ejaculatory latency time was significantly longer after circumcision (P = 0.02). CONCLUSIONS: Adult circumcision does not adversely affect sexual function. The increase in the ejaculatory latency time can be considered an advantage rather than a complication.
