Aims: Bacterial vaginosis (BV) is characterized by a transition in vaginal microflora from lactobacilli to anaerobic bacteria. Gardnerella vaginalis and Atopobium vaginae are considered the most responsible pathogens for the etiology of BV. Colonization of male urethra with BV-associated bacteria has been rarely investigated. The aim of this study was to investigate the differences in the presence of BV-associated bacteria in the healthy male urethra in regard to sexual exposure. Methodology and results: The first-catch urine specimens, representative of urethral swabs, from 114 healthy male volunteers, were included in this study. Lactobacillus spp., L. crispatus, L. jensenii, L. gasseri, L. iners, G. vaginalis, A. vaginae, Peptoniphilus spp., P. lacrimalis, BVAB2, Mageeibacillus indolicus, Megasphaera type I, Mobiluncus mulieris, Leptotrichia/Sneathia, Corynebacterium spp., and Prevotella spp. were investigated using a PCR assay. The most frequently identified BV-associated bacteria were Lactobacillus spp., Peptoniphilus spp., and G. vaginalis. There was no association between any BV-associated bacteria and sexual exposure. There was statistically significant co-occurrence of A. vaginae and G. vaginalis in the MU of subjects independently of sexual exposure (p = 0.025). Also, there was a significant association between G. vaginalis and smoking (p = 0.023). Conclusion, significance and impact of study To the best of our knowledge, this is the first study reporting the co-occurrence of G. vaginalis and A. vaginae in the male urethra independently of sexual exposure.

PURPOSE: Laparoscopic techniques have allowed surgeons to perform complicated intra-abdominal surgery with minimal trauma. Single incision laparoscopic surgery (SILS) was developed with the aim of reducing the invasiveness of conventional laparoscopy. In this study we aimed to compare results of SILS cholecystectomy and three port conventional laparoscopic (TPCL) cholecystectomy prospectively. METHODS: In this prospective study, 100 patients who underwent laparoscopic cholecystectomy for gallbladder disease were randomly allocated to SILS cholecystectomy (group 1) or TPCL cholecystectomy (group 2). Demographics, pathologic diagnosis, operating time, blood loss, length of hospital stay, complications, pain score, conversion rate, and satisfaction of cosmetic outcome were recorded. RESULTS: Forty-four SILS cholesystectomies (88%) and 42 TPCL cholecystectomies (84%) were completed successfully. Conversion to open surgery was required for 4 cases in group 1 and 6 cases in group 2. Operating time was significantly longer in group 1 compared with group 2 (73 minutes vs. 48 minutes; P < 0.05). Higher pain scores were observed in group 1 versus group 2 in postoperative day 1 (P < 0.05). There was higher cosmetic satisfaction in group 1 (P < 0.05). CONCLUSION: SILS cholecystectomy performed by experienced surgeons is at least as successful, feasible, effective and safe as a TPCL cholecystectomy. Surgeons performing SILS should have a firm foundation of advanced minimal access surgical skills and a cautious, gradated approach to attempt the various procedures. Prospective randomized studies comparing single access versus conventional multiport laparoscopic cholecystectomy, with large volumes and long-term follow-up, are needed to confirm our initial experience.

Colloid carcinoma, which is a very rare tumor of the uterine cervix, is composed of an excessive amount of mucus and a relative paucity of tumoral glandular cells within them. Herein, we report a rare case of colloid carcinoma of the cervix with adenocarcinoma in situ (AIS), intestinal and usual types, and endocervical adenocarcinoma (usual type) components. We also discuss the morphological and immunohistochemical characteristics of this tumor. A 51-year-old woman was referred to our outpatient clinic with the symptom of genital bleeding lasting for 5 months. She had a cervix surrounded by an irregular tumor with a diameter of 5 cm. The colloid carcinoma cells were positive for MUC2, MUC5AC, and cytokeratin (CK) 7, focal positive for CDX2, and negative for MUC6 and CK20. Also, the intestinal type AIS showed a similar staining pattern. Colloid carcinoma cells producing mucin showed an intestinal phenotype and AIS. The intestinal type can be considered as a precursor lesion of colloid carcinoma.

PURPOSE: The purpose of this report was to evaluate the effect of the fabrication method and material type on the fracture strength of provisional crowns. MATERIALS AND METHODS: A master model with one crown (maxillary left second premolar) was manufactured from Cr-Co alloy. The master model was scanned, and the data set was transferred to a CAD/CAM unit (Yenamak D50, Yenadent Ltd, Istanbul, Turkey) for the Cercon Base group. For the other groups, temporary crowns were produced by direct fabrication methods (Imident, Temdent, Structur Premium, Takilon, Systemp c&b II, and Acrytemp). The specimens were subjected to water storage at 37degrees C for 24 hours, and then they were thermocycled (TC, 5000x, 5-55degrees C) (n=10). The maximum force at fracture (Fmax) was measured in a universal test machine at 1 mm/min. Data was analyzed by non-parametric statistics (alpha=.05). RESULTS: Fmax values varied between 711.09-1392.1 N. In the PMMA groups, Takilon showed the lowest values (711.09 N), and Cercon Base showed the highest values (959.59 N). In the composite groups, Structur Premium showed the highest values (1392.1 N), and Acrytemp showed the lowest values (910.05 N). The composite groups showed significantly higher values than the PMMA groups (P=.01). CONCLUSION: Composite-based materials showed significantly higher fracture strengths than PMMA-based materials. The CAD-CAM technique offers more advantages than the direct technique.

OBJECTIVE: We aimed to compare the retention characteristics of Essix and Hawley retainers. METHODS: Adolescents undergoing fixed appliance treatment at 2 centers were recruited for this study. Twenty-two patients (16 women and 6 men) wore Essix retainers (Essix group) while 20 (14 women and 6 men) wore Hawley retainers (Hawley group). The mean retention time was 1 year, and the mean follow-up recall time for both groups was 2 years. Two qualified dental examiners evaluated the blind patient data. Maxillary and mandibular dental casts and lateral cephalograms were analyzed at 4 stages: pretreatment (T1), post-treatment (T2), post-retention (T3), and follow-up (T4). RESULTS: The results revealed that Essix appliances were more efficient in retaining the anterior teeth in the mandible during a 1-year retention period. The irregularity index increased in both arches in both groups after a 2-year post-retention period. The mandibular arch lengths increased during treatment and tended to return to their original value after retention in both groups; however, these changes were statistically significant only in the Hawley group. Cephalometric variables did not show any significant differences. CONCLUSIONS: The retention characteristics of both Essix and Hawley retainers are similar.

OBJECTIVE: The aim of the present study was to assess the effect of lumbar disc herniation surgery for low back pain on the erectile functioning. METHODS: Thirty-eight patients, with age ranging from 22 to 56 years, who had presented with pain due to herniated lumbar discs were included in the study. International Index of Erectile Function (IIEF) Short Form questionnaire was used to evaluate the erectile functioning. Patient visits on the 1st week,1st month and 3rd month postoperatively were analyzed. Pain scores were also noted together with side effects and the complications of the surgery. RESULTS: Of the 38 patients, 18 patients had reported erectile dysfunction; 10 patients mild and 8 patients moderate erectile dysfunction. Twenty patients did not report erectile problems. The herniation levels mostly were L5-S1 in 12 (31.6%). Overall, erectile dysfunction rates have improved in 31.7% of those previously with erectile dysfunction in a 3 month period after the surgery. Best results were obtained in those patients with mild erectile dysfunction preoperatively. CONCLUSION: Mild erectile dysfunction together with radiculopathy tends to improve after lumbosacral disc surgery. Moderate and severe erectile dysfunction may be related to a more severe nerve injury or to vascular and/or psychiatric factors. An evaluation of erectile functioning should routinely be performed in patients with lumbosacral disc disease both for data accumulation and for medico legal causes since the documentation of the correlation between erectile dysfunction and lumbosacral disc disease is still lacking.

Background and Objectives: Ideomotor apraxia is an inability to perform a gesture following a verbal command despite having intact knowledge of the task. The presence of ideomotor apraxia may negatively affect functional outcome of stroke patients. The aim of this study was to evaluate the effect of ideomotor apraxia on rehabilitation outcomes following first ever stroke. Methods: A cross sectional observational study of 35 stroke patients admitted to a rehabilitation unit for treatment. Patients were evaluated for ideomotor apraxia using the ideomotor apraxia test. Function was assessed before and after treatment using the Functional Independence Measure, motricity index and functional ambulation scale. Cognitive function was evaluated using the Functional Independence Measure and mini mental state examination. Results: Ideomotor apraxia was present in 31.4% of patients. Mean Functional Independence Measure motor and cognitive scores of apraxic patients on admission and at discharge were lower than those of non-apraxic patients, (p<0.05). The cognitive and total Functional Independence Measure scores and motricity scores in the ideomotor apraxia group on discharge had not reached the admission values of the non-ideomotor apraxia group. Conclusion: The presence of ideomotor apraxia following stroke has a negative impact on overall function, both before and after rehabilitation, when compared to stroke patients without ideomotor apraxia. Stroke patients must be assessed for ideomotor apraxia prior to commencement of a rehabilitation program in order to guide treatment and determine realistic treatment goals.

Background: This study used bibliometric analysis of articles published about the topic of regional anesthesia from 1980-2019 with the aim of determining which countries, organizations, and authors were effective, engaged in international cooperation, and had the most cited articles and journals. Methods: All articles published from 1980-2019 included in the Web of Science database and found using the keywords regional anesthesia/anaesthesia, spinal anesthesia/anaesthesia, epidural anesthesia/anaesthesia, neuraxial anesthesia/ anaesthesia, combined spinal-epidural, and peripheral nerve block in the title section had bibliometric analysis performed. Correlations between the number of publications from a country with gross domestic product (GDP), gross domestic product (at purchasing power parity) per capita (GDP PPP), and human development index (HDI) values were investigated with the Spearman correlation coefficient. The number of articles that will be published in the future was estimated with linear regression analysis. Results: Literature screening found 11,156 publications. Of these publications, 6,452 were articles. The top 4 countries producing articles were United States of America (n = 1,583), Germany (585), United Kingdom (510), and Turkey (386).There was a significant positive correlation found between the GDP, GDP PPP, and HDI markers for global countries with publication productivity (r = 0.644, P < 0.001;r = 0.623, P < 0.001, r = 0.542, P < 0.001). The most productive organizations were Harvard University and the University of Toronto.
