Purpose: To assess the efficacy of preoperative intravitreal bevacizumab injection (IVB) before Ahmed glaucoma valve (AGV) implantation in the treatment of neovascular glaucoma (NVG). Methods: This retrospective, comparative and consecutive case series study included 41 eyes from 41 patients who underwent AGV implantation for treatment of NVG. The study group was composed of 19 patients (19 eyes) to whom IVB was administered before surgery, while the control group was composed of 22 patients (22 eyes) to whom IVB was not administered before AGV implantation. Findings such as intraocular pressures measured before and after surgery, surgical success rates, and postoperative complications were compared between the groups. Results: There were no significant differences in preoperative data between groups. The surgical success rate in the study group (79%) was better than in the control group (64%), but this difference was not statistically significant (p = 0.28). Early postoperative complications such as fibrinous reaction in the anterior chamber as well as hyphema were less frequently observed in the study group. Conclusions: Intravitreal bevacizumab is a useful preparatory step to safely and effectively implant an aqueous shunting tube in eyes with severe NVG and intractable intraocular pressure.

Myeloperoxidase is a lysosomal enzyme of polymorphonuclear leucocytes that contributes to inflamatory responses. In previous studies it was shown that MPO was synthesized in atherosclerotic lesions responsible of lipoprotein oxidations. We aimed to determine the MPO -463 G/A gene polymorphism distribution in Turkish population and evaluate the effects of it on myeloperoxidase levels. There were 100 myocardial infarct patients and 100 healthy control subjects in our study. MPO polymorphism was studied by using PCR-RFLP technique and MPO levels were measured by ELISA. It was shown that MPO levels were increasing in patients after myocardial infarct event but there were no effect of MPO -463 G/A polymorphism on MPO levels. It was also found that serum total cholesterol and LDL-cholesterol levels and smoking was contributing factors in increments of MPO enzymes. We observed that MPO levels were increased in CAD but there were no effect of MPO -463 G/A polymorphism on MPO levels. © 2010 Springer Science+Business Media B.V.

This study aimed to prospectively evaluate patient satisfaction by means of the Rhinoplasty Outcome Evaluation (ROE) questionnaire before and after functional septorhinoplasty. We carefully selected 62 patients (mean age, 31.8 years; 28 men, 34 women) who underwent open functional septorhinoplasty in the Otorhinolaryngology and Head Neck Surgery Department of Suşehri State Hospital. Satisfaction analyses were carried out by means of the ROE questionnaire both before the surgery and at least 4 weeks after the surgery. Patients were divided according to age (≤25 vs >25 years) and follow-up duration (≤6 vs >6 months). In addition, patients were grouped according to their satisfaction scores: 0 to less than 50, bad outcome (group B); 50 to less than 75, good outcome (group G); and 75 or greater, perfect outcome (group P). The mean satisfaction score in all the patients significantly increased after functional septorhinoplasty (from 24.8 ± 14.6 to 70.1 ± 17.3; P < 0.001). Moreover, the increment in mean satisfaction scores did not differ with age or follow-up duration. We conclude that the ROE questionnaire can help surgeons select suitable candidates for functional septorhinoplasty who will most benefit from the surgery. © 2014 by Mutaz B. Habal, MD.

Static magnetic fields are a type of electromagnetic fields used in clinical practice. To ascertain what effect a static magnetic intramedullary device implanted in the rabbit femur had on fracture healing, 20 male New Zealand white rabbits with magnetic/nonmagnetic intramedullary implants were examined histologically, radiologically and for bone mineral density. Three groups were constituted according to the poles of the magnets. During surgery the intramedullary device was driven into the medulla. A femoral osteotomy was created with a mini Gigli wire at the centre point of the rod. Radiographs were obtained at the second and fourth weeks. Histological examination and bone mineral density were evaluated at the fourth week. The results of this study verified that an intramedullary implant with a static magnetic field improves bone healing in the first two weeks radiologically and that the configuration difference in magnetic poles has an effect on bone quality. Static magnetic fields have minor effects on bone mineral density values. © 2010 Springer-Verlag.

It has been suggested that the estrogen receptor alpha (ERα) and vitamin D receptor (VDR) genes as possibly implicated in reduced bone mineral density (BMD) in osteoporosis. The present study investigated the relation of ERα PvuII/XbaI polymorphisms and VDR FokI/TaqI polymorphisms with BMD in Turkish postmenopausal women. Eighty-one osteoporotic and 122 osteopenic postmeno-pausal women were recruited. For detection of the polymorphisms, polymerase chain reaction-restriction fragment lenght polymorphism techniques have been used. BMD was measured at the lumbar spine and hip by dual-energy X-ray absorptiometry. Distributions of ERα (PvuII dbSNP: rs2234693, XbaI dbSNP: rs9340799) and VDR genotypes (FokI dbSNP rs10735810, TaqI dbSNP: rs731236) were similar in study population. Although overall prevalence of osteoporosis had no association with these genotypes, the prevalence of decreased femoral neck BMD values were higher in the subjects with ERα PvuII "PP" and ERα XbaI "XX" genotypes than in those with "Pp/pp" genotypes and "xx" genotype, respectively (P < 0.05). Furthermore, subjects with VDR FokI "FF" genotype had lower BMD values of femoral neck and total hip compared to those with "Ff" genotype (P < 0.05). In the logistic regression analysis, we confirmed the presence of relationships between the VDR FokI "FF" genotypes, BMI ≤ 27.5, age ≥ 55 and the increased risk of femoral neck BMD below 0.8 value in postmenopausal women. The present data suggests that the ERα PvuII/XbaI and VDR FokI polymorphisms may contribute to the determination of bone mineral density in Turkish postmenopausal women. © 2012 Springer Science+Business Media B.V.

Chemokines are potent proinflammatory cytokines that are implicated in numerous inflammatory diseases. Proinflammatory gene polymorphisms lead to variations in the production and concentration of inflammatory proteins. We investigated a possible association between polymorphisms in chemokine and chemokine receptor genes (MCP-1 A-2518G and CCR2-V64I) and bladder cancer risk. Genotypes were determined by PCR-RFLP assays in 72 bladder cancer patients and 76 unrelated age-matched healthy controls. There were significant differences in the frequencies of the MCP-1 A-2518G (P = 0.012) and CCR2-V64I genotypes (P = 0.004) between the controls and patients. The MCP-1 A-2518G GG genotype frequencies for controls and cases were 0.039 and 0.11, respectively; individuals who had the GG genotype had a 3-fold increased risk of bladder cancer (P = 0.08). The CCR2-64I/64I genotype frequencies for controls and cases were 0.02 and 0.13, respectively; subjects carrying the 64I/64I genotype had a 5.9-fold increased risk of bladder cancer compared to the other genotypes. Individuals carrying the CCR2-V64I heterozygote or homozygous variant genotype (64I/64I + wt/64I) had a 2.9-fold increased risk of bladder cancer compared with the wild-type genotype (wt/wt). CCR2-V64I heterozygote or homozygous wild-type genotype (wt/wt + wt/64I) frequencies were significantly decreased in the patient group compared with controls. We conclude that CCR2-64I is a new risk factor for bladder cancer. © FUNPEC-RP.

Identification of risk factors for osteoporosis has been essential for understanding the development of osteoporosis. The collagen type I alpha1 (COL1A1) gene is suggested to be implicated in reduced bone mineral density (BMD) in osteoporosis. In the present study, the investigation of the effects of Sp1 polymorphic variants of COL1A1 gene on BMD values, and the determination of the association between COL1A1 Sp1 gene variants and osteoporosis risk factors in the context of gene-environment interaction in Turkish postmenopausal women were aimed. For the detection of COL1A1 Sp1 polymorphism, PCR-RFLP techniques have been used. BMD for lumbar spine (L1-L4) and hip (femoral neck and total hip) was measured by DXA. This study was carried out using a sample of 254 postmenopausal women. We observed a trend decrease in BMD values in the subjects with "ss" genotype having lower BMD of lumbar spine, femoral neck and total hip than those with "SS" and "Ss" genotype, however the differences did not reach statistical significance (P> 0.05). We also found that the frequencies of the BMD under mean values at the femoral neck (57.5%) and total hip (76.2%) increased considerably in the subjects carrying "Ss/ss" genotypes in combination of having family history of osteoporosis (61.5% for femoral neck) and smoking history (90.0% for total hip). This population-based study indicates that COL1A1 Sp1 polymorphism may contribute to the development of osteoporosis in combination of osteoporosis risk factors in Turkish postmenopausal women. © 2014 Elsevier B.V.

Hypothesis: Double-row rotator cuff repair leads to superior cuff integrity and clinical results compared with single-row repair. Materials and methods: The study enrolled 68 patients with a full-thickness rotator cuff tear who were divided into 2 groups of 34 patients according to repair technique. The patients were followed-up for at least 2 years. The results were evaluated by Constant score. Discussion: Despite the biomechanical studies and cadaver studies that proved the superiority of double-row fixation over single-row fixation, our clinical results show no difference in functional outcome between the two methods. It is evident that double-row repair is more technically demanding, expensive, and time-consuming than single-row repair, without providing a significant improvement in clinical results. Results: Comparison between groups did not show significant differences. At the final follow-up, the Constant score was 82.2 in the single-row group and 78.8 in the double-row group. Functional outcome was improved in both groups after surgery, but the difference between the 2 groups was not significant. Conclusions: At long-term follow-up, arthroscopic rotator cuff repair with the double-row technique showed no significant difference in clinical outcome compared with single-row repair in small to medium tears. © 2010 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: To investigate the role of peak nasal inspiratory flowmetry (PNIF) in evaluating inspiratory improvements in patients who underwent both septoplasty and inferior turbinate coblation by radiofrequency (ITC-RF). Methods: One hundred and eight patients underwent both Cottle's septoplasty and ITC-RF. PNIF measurements were performed in all patients in the preoperative period and 6 months postoperatively. All measurements were made both before and after decongestion of the nasal cavity with oxymetazoline spray. Results: Mean preoperative PNIF measurements differed significantly: 104.3 ± 33.6 L/min vs 136.1 ± 27.7 L/min before and after oxymetazoline decongestion, respectively. Mean postoperative PNIF measurements were 139.2 ± 30.8 L/min and 151.2 ± 32.3 L/ min before and after decongestion, respectively. Preoperatively the mean difference between before and after decongestion was 32.1 ± 16.3 L/min. Postoperatively the mean difference was 11.8 ± 11.1 L/min. Conclusion: PNIF can be used in the assessment of ITC-RF outcomes with the aid of nasal decongestants, even in patients who also underwent septoplasty.

Purpose: The evaluation of anatomic and visual outcomes in macular hole cases treated with internal limiting membrane (ILM) peeling, brilliant blue (BB), and 23-gauge pars plana vitrectomy (PPV). Materials and methods: Fifty eyes of 48 patients who presented between July 2007 and December 2009 with the diagnosis of stage 2, 3, or 4 macular holes according to Gass Classification who had undergone PPV and ILM peeling were included in this study. Pre- and postoperative macular examinations were assessed with spectral-domain optical coherence tomography. 23 G sutureless PPV and ILM peeling with BB was performed on all patients. Results: The mean age of patients was 63.34 ± 9.6 years. Stage 2 macular hole was determined in 17 eyes (34%), stage 3 in 24 eyes (48%), and stage 4 in 9 eyes (18%). The mean follow-up time was 13.6 ± 1.09 months. Anatomic closure was detected in 46/50 eyes (92%), whereas, in four cases, macular hole persisted and a second operation was not required due to subretinal fluid drainage. At follow-up after 2 months, persistant macular hole was detected in one case and it was closed with reoperation. At 12 months, an increase in visual acuity in 41 eyes was observed, while it remained at the same level in six eyes. In three eyes visual acuity decreased. There was a postoperative statistically significant increase in visual acuity in stage 2 and 3 cases (P < 0.05), however, no increase in visual acuity in stage 4 cases was observed. Conclusion: PPV and ILM peeling in stage 2, 3, and 4 macular hole cases provide successful anatomic outcomes, however, in delayed cases, due to photoreceptor loss, it has no effect on functional recovery. BB, used for clarity of ILM, may be beneficial due to its low retinal toxicity. © 2011 Sanisoglu et al, publisher and licensee Dove Medical Press Ltd.
