- Abstract
Adhesive capsulitis is an idiopathic condition characterized by painful shoulder stiffness, impairs quality of life, and causes disability. The purpose of the study is to evaluate the effects of high-intensity laser therapy (HILT) on pain, disability, and quality of life in patients with adhesive capsulitis. The study was designed as a prospective, double-blinded, and sham-controlled randomized trial. Thirty-six patients diagnosed with adhesive capsulitis were randomized into HILT plus therapeutic exercises, sham-laser plus therapeutic exercises, and control-therapeutic exercises only groups. All groups received 25 min of exercises to the shoulder joint supervised by a physiotherapist. Patients in both the HILT and the sham-laser group were blinded to their group randomization. The interventions were performed five times a week for 3 weeks (a total of 15 sessions). The primary outcome measure was the visual analogue scale for pain (Visual Analog Scale for pain (VAS)-pain). The secondary outcome measures were shoulder pain and disability index (SPADI), short-form health survey-36 (SF-36), and range of motion (ROM) of the shoulder joint. Assessments were performed at pre-intervention, post-intervention, and 12-week follow-up by an investigator who was blinded. Thirty-one participants completed the study. HILT plus therapeutic exercises showed significant differences in VAS-pain, SPADI-pain, and SF-36 (subgroups of energy/fatigue, pain, and general health) scores (all P < 0.05). All groups provided comparable improvements in SPADI-disability and ROM of shoulder joint after the interventions and during the follow-up (all P < 0.05). Fifteen sessions of HILT are superior to improve pain and quality of life but not superior in terms of disability or function in patients with adhesive capsulitis. Clinical trial registration number: The study was registered at the US National Institutes of Health ( ClinicalTrials.gov ) (NCT03929276) and available at https://clinicaltrials.gov/ct2/show/NCT03929276?term=tu%C4%9Fba+atan&draw=2&rank=3.

- Abstract
Introduction: To evaluate the prognostic value of the Glasgow Prognostic Score (GPS), the combination of C-reactive protein (CRP) and albumin, in glioblastoma multiforme (GBM) patients treated with radiotherapy (RT) and concurrent plus adjuvant temozolomide (GPS)., Methods: Data of newly diagnosed GBM patients treated with partial brain RT and concurrent and adjuvant TMZ were retrospectively analyzed. The patients were grouped into three according to the GPS criteria: GPS-0: CRP < 10 mg/L and albumin > 35 g/L; GPS-1: CRP < 10 mg/L and albumin < 35 g/L or CRP > 10 mg/L and albumin > 35 g/L; and GPS-2: CRP > 10 mg/L and albumin < 35 g/L. Primary end-point was the association between the GPS groups and the overall survival (OS) outcomes., Results: A total of 142 patients were analyzed (median age: 58 years, 66.2% male). There were 64 (45.1%), 40 (28.2%), and 38 (26.7%) patients in GPS-0, GPS-1, and GPS-2 groups, respectively. At median 15.7 months follow-up, the respective median and 5-year OS rates for the whole cohort were 16.2 months (95% CI 12.7-19.7) and 9.5%. In multivariate analyses GPS grouping emerged independently associated with the median OS (P < 0.001) in addition to the extent of surgery (P = 0.032), Karnofsky performance status (P = 0.009), and the Radiation Therapy Oncology Group recursive partitioning analysis (RTOG RPA) classification (P < 0.001). The GPS grouping and the RTOG RPA classification were found to be strongly correlated in prognostic stratification of GBM patients (correlation coefficient: 0.42; P < 0.001)., Conclusions: The GPS appeared to be useful in prognostic stratification of GBM patients into three groups with significantly different survival durations resembling the RTOG RPA classification.

- Abstract
A 38-year-old male presented to the emergency department with abdominal pain and bulge. He had a history of irritable bowel syndrome for 1 year with complaint of dyspepsia. Physical examination revealed a distended abdomen with a huge palpable mass located in the paraumblical region. Laboratory findings revealed a high white blood cell count with neutrophil predominance. Contrast-enhanced computed tomography (CT) showed a 23-cm, oval-shaped, grossly necrotic, low-attenuation mass with peripherally located dominant vessels. Magnetic resonance imaging (MRI) with diffusion weighted imaging (DWI) suggested a highly malignant tumor with prominent diffusion restriction especially at the periphery of the mass. On surgery, macroscopic examination showed a macrolobulated, hypervascular, reddish brown mass attached to the parietal peritoneum with a stalk. Ewing's sarcoma (ES) was diagnosed on histopathological examination with small round cells.

- Abstract
To assess the efficacy of whole-brain radiotherapy (WBRT) and prognostic factors in leptomeningeal carcinomatosis (LMC) of non-small-cell lung cancer (NSCLC) patients. WBRT records of 51 LMC patients confined to brain were reviewed. Eligible patients had squamous-cell carcinoma (SCC) or adenocarcinoma, and Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0-3. The WBRT was either 20 or 30 Gray. The primary and secondary objectives were to determine overall survival (OS) and prognostic factors for improved treatment response, respectively. Median age was 53 years (range 39-68), 58.8 % had SCC, 74.5 % had ECOG PS 1-2, and 70.6 % had LMC accompanied by parenchymal brain metastases (BM). The median follow-up was 4.1 months (range 0.7-14.4); all patients died due to disease progression. Median OS was 3.9 months (95 % CI 3.3-4.5) with 6 and 12 month estimates of 19.6 and 5.9 %, respectively. Evaluation of prognostic factors revealed that patients with ECOG 1, longer time to LMC (TT-LMC) from NSCLC diagnosis (>11.3 months), and absence of parenchymal BM had significantly superior OS than those patients with ECOG 2 (p = 0.01) or 3 (p < 0.001), TT-LMC < 11.3 months (p = 0.001), and parenchymal BM (p = 0.012). Median OS of 3.9 months after WBRT appeared to confirm the poor prognosis of LMC. WBRT might be most effective for patients with favorable PS, longer TT-LMC, and no accompanying BM. Therefore, we identified ECOG PS 1, TT-LMC > 11.3 months, and no BM as independent prognosticators for better response to WBRT in NSCLC patients with LMC.

- Abstract
The use of mesh has become the gold standard in hernia operations recently due to advantages such as lower recurrence rates, lower post-surgical pain and earlier return to work. Plug mesh application, first described by Robins and Rutkow [Robbins AW, Rutkow IM (1993) The mesh-plug hernioplasty. Surg Clin North Am 73:501-512], is a popular method of hernia repair. Although rare, there may be complications of surgery using plug mesh. This report presents a case of mechanic bowel obstruction due to mesh migration, 3 years after a left inguinal hernia repair with plug mesh method.

- Abstract
Purpose: The two most common procedures for open tension-free groin hernia repair with prosthetic mesh are the Lichtenstein operation and the mesh plug (Rutkow-Robbins) technique. Our study evaluated these two techniques on testicular blood flow and volume, and sperm function in young adults., Methods: We randomized operation types with a systematic sampling method, and handled consecutive patients of age 20-30 years having unilateral inguinal hernia repair at our institution from March to August 2008. The study subjects were divided into the Lichtenstein group (LG) and the mesh plug group (MPG). All subjects received color Doppler ultrasonography to determine testicular volume and resistive index (RI) the day before surgery and 3 months postoperatively by a physician blinded for the type of planned or performed operation. Spermiograms done preoperatively and at 3 months postoperatively measured sperm concentration and the rate of progressive motility., Results: Sixty-four patients met the study criteria, with 32 patients each in the LG and MPG. RI levels were elevated postoperatively in both the LG (P = 0.027) and MPG (P = 0.012); there was no significant alteration in terms of testicular volume and spermiogram in the LG and MPG., Conclusion: The Lichtenstein and mesh plug techniques in unilateral inguinal hernia increase the RI level significantly in the early postoperative period, but do not have a significant effect on sperm concentration and the rate of progressive motility.

- Abstract
Selenoproteins are enzymes containing selenium in their structure and are involved in cellular processes such as defense against oxidative stress and cell survival. The aim of this study is to investigate the expression of four selenoproteins (GPX1, TRXR1, SELP and SELW) in the hippocampus of intractable mesial temporal lobe epilepsy (MTLE) patients who underwent curative surgery. The selenoproteins is investigated at the mRNA level via RT-PCR and in situ hybridization and by immunostaining at the protein level. The expression of SELW exhibited a relative induction of more than tenfold, and immunostaining findings provided evidence that this upregulation is confined to neurons. GPX1 was also upregulated 2.3-fold, and TRXR1 was downregulated between 70 and 20% in MTLE patients. The profound induction of SELW has been accompanied by GPX1 and displayed a strong correlation with BCL2 expression, suggesting a protective role for these selenoproteins, and may be an indicator of a defense mechanism in surviving neurons.

- Abstract
Quality of life (QoL) and life satisfaction (LS) are important outcome factors in chronic inflammatory conditions such as Behçet's disease (BD). The aim of this study was to investigate QoL and LS in patients with BD and determine the relationship with disease activity. Forty-one patients with BD and 40 control subjects were involved in the study. Demographic properties were obtained. Disease activity was assessed by Turkish version of BD Current Activity Form (BDCAF) in BD patients. QoL and psychological well-being were assessed by Nottingham Health Profile (NHP) and Life Satisfaction Index (LSI), respectively, in both patients and control groups. The related disease activity measures of QoL and LS were determined. Twenty-two male and 19 female BD patients with a mean age of 33.3+/-9.3 years and 20 male and 20 female control subjects with a mean age of 33.3+/-4.1 years were involved. According to BDCAF, no patient had central nervous system involvement. Thirty-four patients had headache, 33 patients had fatigue, 30 patients had articular involvement, 29 had mucocutaneous lesions, 27 had gastrointestinal involvement, 21 patients had ocular involvement, and 7 patients had vascular involvement. The scores of all dimensions of NHP were significantly higher and the mean score of LSI was significantly lower in BD patients than in control subjects (p<0.001). Correlation analysis indicated that the scores of fatigue, joint involvement, and oral ulcers were the most related factors for physical domains of NHP, whereas joint involvement and genital ulcers were the most related activity measures for psychosocial subscales of NHP. LS was found to be most related with the scores of patient's and physician's impression of disease activity and joint involvement. In conclusion, patients with BD have impaired QoL and disturbed psychological well-being. Current management strategies focusing on fatigue, arthralgia, mucocutaneous lesions, and efforts to measure psychosocial aspects and symptoms of the patients by their point of view will help to improve QoL and raise the LS in patients suffering from BD.

- Abstract
Polyurethane membranes were prepared under nitrogen atmosphere by using various proportions of toluene diisocyanates (TDI) and polypropylene-ethylene glycol (P) with addition of no other ingredients such as catalysts, initiator or solvent in order to achieve medical purity. Effects of composition on mechanical properties were examined. In general, modulus and UTS values demonstrated an increase and PSBR demonstrated a decrease as the TDI/Polyol ratio of the polymer increased. Elastic modulus, ultimate tensile strength (UTS) and per cent strain before rupture (PSBR) values were found to be in the range of 1.4-5.4 MPa, 0.9-1.9 MPa, and 60.4-99.7%, respectively. Surfaces of the membranes were modified by oxygen plasma applying glow-discharge technique and the effect of applied plasma power (10 W or 100 W, 15 min) on surface hydrophilicity and on the attachment of Vero cells were studied. Water contact angle values of the plasma modified surfaces varied between 67 degrees and 46 degrees, demonstrating a decrease as the applied plasma power was increased. The unmodified material had 42-45 cells attached per cm(2). It was observed that as the applied power increased the number of attached cells first increased (60-70 cells/cm(2) at 10 W) and then decreased (27-40 cells/cm(2) at 100 W). These demonstrated that surface properties of polyurethanes can be modified by plasma-glow discharge technique to achieve the optimum levels of cell attachment.
