Prospective multicenter clinical trial of Uretex Sup for surgical treatment of stress urinary incontinence

AIM: To evaluate in a prospective multicenter study the efficacy and safety of the suburethral support Uretex (Sofradim, Trevoux, France) delivered by a suprapubic approach in the treatment of female stress urinary incontinence. METHODS: Between March 2002 and March 2003, 57 patients were treated for stress urinary incontinence with Uretex. Preoperative evaluation included urodynamic examination and questionnaires (symptoms and quality of life, Contilife). Forty patients had pure stress urinary incontinence and 17 mixed urinary incontinence. No associated procedure was performed. The objective cure rate was evaluated by clinical examination and pad-test, and the subjective cure rate was assessed through questionnaires at 1, 3 and 12 months. RESULTS: The mean follow-up was 13 months (range 11-24 months). During follow up, chronic urinary retention requiring a tape section occurred in one patient, and in another patient a delay of vaginal healing was followed by a sling exposure and resection at 4 months. No infection or urethral erosion was reported. The objective cure rate was 96.2%, and the subjective cure rate was 79.2%; four patients reported low leakage on stress and nine patients complained of urge incontinence (four de novo and five persistent). CONCLUSION: The suprapubic Uretex Sup procedure is a safe and effective treatment for women with stress urinary incontinence.     

The effects of female age on the outcome of testicular sperm extraction and intracytoplasmic sperm injection in infertile patient with azoospermia

Introduction: Testicular sperm extraction (TESE) is well-defined procedure for surgical sperm retrieval in obstructive and non-obstructive azoospermia. This study was focused on the effectiveness of testicular sperm extraction and intracytoplasmic sperm injection (ICSI) for azoospermic men with different female age subgroups.Materials and methods: A total of 107 men with azoospermia underwent TESE and ICSI treatment. The women were examined in three groups 20–29, 30–34 and 35 years or older. The main outcome in this study was fertilization and pregnancy rates with TESE and ICSI.Results: Spermatozoa were successfully retrieved during 97 of 107 (90.7%) TESE attempts, resulting in the fertilization of 286 of 563 (50.4%) injected metaphase II oocytes. Two hundred and fifty-five of them were transferred (89.8%). The clinical pregnancy rate and ongoing pregnancy rate per embryo transfer were 22.5% and 20.6% respectively. When comparing the fertilization and pregnancy rates, it was observed that women between the ages of 20–29 years had significantly higher pregnancy rates than women over 34 years of age (p < 0.05).Conclusion: The female age is a major factor in determining successful implantation in ICSI.     

Evaluation of prosthetic mesh closure in semiopen-abdomen patients

Abstract Background. To avoid the adverse consequences of abdominal compartment syndrome and to reduce the high mortality the celiotomy wound in patients with abdominal sepsis was closed without tension using prosthetic mesh. This produces a semiopen situation that permits staged reinterventions together with the functional reconstitution of the continuity of the abdominal wall. Material and Methods. Twenty-five patients with intra-abdominal sepsis of various causes were evaluated retrospectively to assess the results of semiopen management of the septic abdomen and reoperations on demand in severe peritonitis. All of the patients were in a state of neglected peritonitis, and had at least one failing organ system. The Mannheim Peritonitis Index (MPI) scoring system was used for stratification of abdominal sepsis. Results. The mean MPI score of 25 patients was 24, ranging 10 to 33. Eight (32%) patients were reexplored (MPI=21). There were overall 9 (36%) complications in patients with mean MPI score of 23. Six (24%) mesh-related complications (infection and enterocutaneous fistulas) developed (MPI=19). The mean MPI score of patients without complications was 24. Four (16%) patients died with index MPI score of 26 due to fulminant hepatitis, myocardial infarction, and multiple organ failure. The admission period averaged 63 days. Conclusions. In 25 critically ill patients with abdominal sepsis the mortality was lower than expected, relative to heterogeneous data from the literature; also, major complications occurred less frequently although the mean MPI score was high. The authors conclude that this approach is a reliable contribution to the complex treatment of these patients. Electronic Publication     

Effects of erbium:yttrium–aluminum–garnet and neodymium:yttrium–aluminum–garnet laser hypersensitivity treatment parameters on the bond strength of self-etch adhesives

This in vitro study evaluated the shear bond strength (SBS) of two self-etch adhesives to coronal and root dentin treated with erbium:yttrium–aluminum–garnet (Er:YAG) or neodymium:yttrium–aluminum–garnet (Nd:YAG) lasers for dentin hypersensitivity. The coronal and root dentin surfaces of 60 extracted human cuspids were divided into three groups (n = 20): (1) control (without treatment); (2) treated with Er:YAG; (3) treated with Nd:YAG laser and a one-step (S3) or two-step self-etch adhesive (SE). A nano-composite was applied and SBS tests were performed. The mean SBS values were calculated, failure modes were determined, and data were subjected to statistical analysis (P = 0.05). Control/SE exhibited higher values than did control/S3 and Nd:YAG/S3 on coronal dentin (P < 0.05). No significant differences were observed between the SE and S3 groups in root dentin (P > 0.05). Comparisons of two dentin substrates did not show any difference except control/SE (P < 0.05). The failure modes were mainly adhesive. The SBSs of self-etch adhesives to Er:YAG or Nd:YAG laser-treated surfaces were comparable with control for both coronal and root dentin.     

The relationship between methylenetetrahydrofolate reductase c.677TT genotype and oligozoospermia in infertile male patients living in the Trakya region of Turkey

Methylenetetrahydrofolate reductase (MTHFR), the key enzyme of the folate metabolic pathway, has been reported to be five times more active in the testicles compared to other organs in adult mice. The aim of this study was to investigate the relationship between MTHFR c.677C>T and c.1298A>C polymorphisms and infertility in nonobstructive azoospermic and oligozoospermic male patients living in the Trakya region of Turkey. The study population included 75 nonobstructive azoospermic and 62 oligozoospermic, nonconsanguineous patients who were referred to the Department of Medical Genetics of Trakya University between 01.03.2012 and 01.06.2013 due to infertility and who had been diagnosed based on clinical examinations and spermiograms. All of the patients had a normal karyotype without a Y chromosome microdeletion. Melting curve analysis with labelled probes and primers that were designed by the manufacturers and the real‐time polymerase chain reaction method were used. The MTHFR c.677TT genotype frequency in the oligozoospermic infertile male patient group was greater than that of the fertile control group [odds ratio (OR) = 2.675 (95% CI: 0.979–7.305), (P < 0.048)]. The MTHFR c.677TT genotype may be a genetic risk factor for oligozoospermic infertile male patients who live in the Trakya region of Turkey.     

The Top 100 Most-Cited Articles on Hallux Valgus

BackgroundTo perform the citation and content analysis of 100 articles on Hallux valgus from the most cited to the least.Materials and methodsArticles published on Hallux valgus between 1980 and 2020 were analyzed by making use of the Web of Science database. Articles were ranked from most cited to the least. Content analysis of all articles was also carried out. Original research articles, reviews, and clinical trials were included in the study whereas case reports were excluded from the study.ResultsThe total number of citations of the 100 most-cited articles was 7,697. The most-cited article was ‘Prevalence of hallux valgus in the general population; systematic review and meta-analysis’ published by Sheere Nix in Journal of Foot and Ankle Research in 2010. The country where the articles were mostly produced was USA (n = 46). The most interesting issue was the osteotomy techniques and changes in Hallux valgus surgery.ConclusionThe treatment of the Hallux valgus disease is still discussed today. Citation analyses have shown that surgical developments related to HV surgery still attract attention, and this information will be updated continuously in line with the increasing number of articles.     

Preoperative Nutritional Risk Assessment in Predicting Postoperative Outcome in Patients Undergoing Major Surgery

Introduction Although a variety of nutritional indices have been found to be valuable in predicting patient outcome when used alone, there is no consensus on the best method for assessing the nutritional status of hospitalized patients. Therefore, the aim of this study was to assess the nutritional status of a cohort of patients who underwent major elective surgery using the Nutritional Risk Index (NRI), Maastricht Index (MI), Subjective Global Assessment (SGA), and Mini Nutritional Assessment (MNA) to determine the best possible nutrition screening system in surgical practice. Methods The study population consisted of 460 patients who underwent major elective surgery between December 1999 and March 2002. Each patient had a complete set of the three nutritional assessment techniques (NRI, MI, SGA); in addition, the MNA was performed in patients older than 59 years of age. One of the coauthors who was unaware of the nutritional assessments assessed the patients for postoperative morbidity and mortality. Complications were classified as major or minor and as infectious or noninfectious. To assess the predictive value of the assessment techniques, likelihood ratios were calculated for the various strata of each method. The odds ratio and receiver operating characteristic (ROC) curves were also calculated to describe and compare the diagnostic value of each of the four nutrition indices. Results Twenty patients died during the study period. No complications occurred in 329 of the 460 patients; 42 patients suffered from two or more complications. The frequency of malnutrition was found to be 58.3%, 63.5%, and 67.4% as assessed by the SGA, NRI, and MI, respectively. Morbidity rates, especially severe infectious and noninfectious complications, were significantly higher in malnourished patients in all nutritional indices. The likelihood ratio was well correlated with the risk categories of every nutritional index. The area under the ROC curves revealed that each scoring system proved to be significantly powerful in predicting the morbidity (infectious and noninfectious severe morbidity) and mortality. However, no differences were detected among the nutritional indices in 460 patients. The odds ratio for morbidity between the well nourished and malnourished patients was 3.09 [95% confidence interval (CI), 1.96–4.88], 3.47 (95% CI, 2.12–5.68), 2.30 (95% CI, 1.43–3.71), and 2.81 (95% CI, 0.79–9.95) for the SGA, NRI, MI, and MNA, respectively. All indices except the MNA were significantly predictive for morbidity. The odds ratios were not statistically different among the indices. Conclusions Our findings revealed that all nutritional assessment techniques can be safely applied to the clinical setting with no significant difference in predictive value. We therefore strongly recommend the use of any of these techniques to improve the outcome of surgical care. Meanwhile, further investigations are needed, and much effort must be given to find the best method for assessing nutritional status. This work was presented at a conference of the European Society for Clinical Nutrition and Metabolism (ESPEN), August 31 to September 4, 2002, Glasgow, UK.     

Evaluation of the effect of shift working and sleep quality on semen parameters in men attending infertility clinic

We aimed to evaluate the effect of shift work on semen parameters together with the effect of sleep quality in men attending infertility clinic. The participants were divided into two groups as follows: 104 shift worker men (Group 1) and 116 nonshift worker men (Group 2). Groups were compared in terms of semen parameters, Depression Anxiety Stress Scale-21 (DASS-21), and Pittsburg Sleep Quality Index (PSQI) scores. A higher rate of oligozoospermia and poor sleep quality and a lower mean normal morphology percentage was observed in shift workers than nonshift workers (p = .006, .039 and .036 respectively). In addition, a positive correlation was seen between sleep duration and sperm concentration, while a negative correlation was found between sleep latency and total sperm count. Shift working together with high PSQI score was also a significant association with oligozoospermia when controlling for the other variables of age, total testosterone, DASS-21 stress score, smoking and varicocele (OR = 2.11, 95% CI 1.03–4.34 and OR = 1.18, 95% CI 1.01–1.39 respectively). In this study, infertile shift workers had a lower percentage of normal morphology and higher rates of oligozoospermia and poor sleep quality. Considering that shift workers have lower sleep quality, it seems that shift working negatively affects the circadian rhythm.     

Multicentral clinical evaluation of the aetiology of erectile dysfunction: A survey report

Patients with erectile dysfunction, who admitted to 4 different urological centres in Turkey were evaluated in terms of aetiological factors to establish the aetiology of erectile dysfunction in our population and compare it with the data derived from Western communities. After the history, physical examination, psychological evaluation and laboratory testing, a clinical diagnosis was established as primarily psychogenic, organic, or mixed aetiology. Mean patient age was 43.5 years (range 17 to 69), and 9 of the patients were unmarried. Of the patients 53 had vascular risk factors, and 10 reported a history of alcohol abuse. Eleven patients were using drugs that might interfere with the disorder. In this multicentral study of 115 impotent men, an organic cause was found in 43%, psychogenic in 47%, and mixed in 19%. Mean age of the overall patients was 43.48. When the ages of the patients with organic erectile dysfunction and those with psychogenic erectile dysfunction were compared, it was clearly seen that those with organic erectile dysfunction were much older (52.73 versus 33.02). This revised version was published online in June 2006 with corrections to the Cover Date.     

Management of Esophageal Perforation

Despite recent advances in thoracic surgery, the management of esophageal perforation remains problematical and controversial. Thirty-one patients were treated for an esophageal perforation between 1986 and 1998. The esophageal perforation was iatrogenic in 25 cases, spontaneous in 2, traumatic in 2, and caused by a tumor and tuberculous lymphadenitis in 2 patients. There were 10 cervical, 19 thoracic, and 2 abdominal perforations. The interval from perforation to operation was less than 24 h in 12 patients and more than 24 h in 19 patients. The surgical procedures included a primary repair in 12 patients, a resection in 8, and conservative treatment with minor surgical approaches in 11. The mortality rate was 20% (4/20 patients) in the surgical treatment group and 45.5% (5/11 patients) in the conservative treatment with minor surgery group. The overall mortality was 29% (9/31 patients). The prognosis is thus concluded to depend on the cause and location of the perforation, the presence of underlying esophageal diseases, and the surgical procedure chosen.
