Effect of Preoperative Mastoid Ventilation on Tympanoplasty Success

Purpose. This study was conducted with the aim of investigating the relationship between mastoid air cell volumes and graft success after tympanoplasty. Material and Methods. This study was performed retrospectively with patients undergoing type I tympanoplasty and antrostomy. A total of 57 patients (20–35.09% female and 37–64.91% male) with a mean age of 29.69±SD (range 12–56 years) were included in the study. The patients were invited for a control at the 1st, 3rd, and 12th months, and otoscopic examinations and audiometric tests were performed. The temporal bone computed tomography images were screened with the 4800 Dpi optic resolution scanner and transferred to the computer environment in JPG format in order to calculate the mastoid air cell volume, and the volumes were calculated using the Autocad 2007 program. Results. Although, the graft success was determined to be better in the well-ventilated group, no significant difference could be found between the groups in terms of graft success at the 1st, 3rd, and 12th months (P>0.05). No statistically significant difference could be found between the three groups in terms of the preoperative and postoperative hearing gains (P>0.05)

IS MESH USE NECESSARY FOR LAPAROSCOPIC SMALL VENTRAL HERNIA REPAIR?

Objective: Ventral hernias smaller than 3 cm are commonly repaired via minor surgical interventions. Primary repair and/or repair with mesh are the most commonly used techniques, but there is no consensus in the literature about the most appropriate repair method. In this study, we aimed to evaluate the early results of patients who underwent primary transcutaneous laparoscopic ventral hernia repair for a ventral hernia smaller than 3 cm

Effects of Sleeping Positions on the Rotator Cuff Pathology

The rotator cuff tear aetiology is still unclear. Especially for atraumatic ruptures, degenerative processes come into prominence. This study aims to correlate between four most commonly-seen sleeping positions and patients with rotator cuff pathology. 87 patients who applied to the institute for suffering from shoulder pain for more than 6 months without a trauma and 93 voluntary people (as control group) above the age of 50 who applied to the institution for reasons other than shoulder pain included in the study. Rotator cuff ruptures and acromion types of the patients are diagnosed via magnetic resonance imaging. In face-to-face interviews, all the patients are asked to show their favourite sleeping positions on the visual cards and also questioned about their smoking habits and overhead activities. There is not any statistically substantive parameters between the patients and the control group in terms of age and sex. 83.9% of the patients with rotator cuff rupture have stated prefering lateral decubitus position while this rate is %61.3 among the control group (p=0.003). Atraumatic rotator cuff tears are increase with age. The increase pressure in the subacromial space can lead distribution in microvascular circulation of rotator cuff. Decrease in the microvascular circulation also affect the regeneration potential of rotator cuff. Laboratory studies demonstrated that lateral decubitus position has the most prominent increase in the subacromial pressure over all sleeping positions. We consider that sleeping in the lateral decubitus position causes long-term high subacromial pressure, leading to a microcirculatory disorder in the rotator cuff, which is a risk factor for the rotator cuff aetiology.

Use of soluble complement receptor type 1 to prevent local and distant organ injury in a rat intestinal ischemia reperfusion model

Introduction: In this experimental study we aimed to examine the in vivo effect of soluble complement receptor type 1 (sCR1) in preventing local and distant organ injury in an ischemia reperfusion model via the superior mesenteric artery (SMA). Using these data, it may be possible to determine the clinical usage of sCR1. Material and Methods: 24 male rats, weighing between 200 and 250 g, were classified into four groups. In group 1, the SMA was clamped for 60 minutes. In group 2, intravenous (IV) sCR1 was given after laparotomy. In group 3, the SMA was clamped for 60 min, at the 60th minute IV sCR1 was administered, and then 1 min later reperfusion was carried out. Group 4 was the laparotomy group. To investigate organ injury, liver function tests (serum AST and ALT levels) and kidney function tests (serum BUN and creatinine levels) were carried out. To evaluate the systemic and local effects of inflammation, total serum levels of protein, albumin, tumour necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) were tested. In tissue samples, glutathione (GSH), malondialdehyde (MDA), and myeloperoxidase (MPO) positive neutrophil counts were identified. Results: According to the statistical analysis, sCR1 was shown to reduce the ischemia-reperfusion injury and have antiinflammatory effects. In addition, distant organ injury due to reperfusion was prevented by sCR1. Conclusion: sCR1 was verified to decrease both mortality and morbidity. [Arch Clin Exp Surg 2017; 6(3.000): 126-131

Evaluation of Follow-Up and Treatment Results in Coats’ Disease

Objectives: The aim of this study was to evaluate the clinical features, follow-up and treatment results of patients diagnosed with Coats’ disease. Materials and Methods: Medical records of 27 patients diagnosed with Coats’ disease in our clinic were reviewed retrospectively. All patients underwent complete ophthalmological examination and fundus photography was taken. Disease stage and treatment methods used were recorded. Results: Twenty-seven eyes of 27 patients were included in the study. Mean age was 9.03 years; 21 patients were male and 6 were female. Three patients were older than 18 years old. Based on the Shields classification, 1 (3.7%) eye was stage 2A, 4 (14.8%) eyes were stage 2B, 6 (22.2%) were stage 3A1, 3 (11.1%) were stage 3A2, 1 (3.7%) was stage 3B, 4 (14.8%) were stage 4 and 8 (29.6%) were stage 5. Fourteen patients underwent treatment, 12 of whom had combined therapy. The most common treatment modalities were laser photocoagulation and cryotherapy. Encircling band was done in one patient and pars plana vitrectomy in 3 patients. Enucleation was done in 5 patients. Conclusion: Coats’ disease is a chronic disease and main goal of treatment is to eliminate the vascular anomalies and their complications using repetitive combination therapies. Treatment in the early stages can lead to functional success, and in advanced stages can result in a salvageable eye

The Role Of Fecal Calprotectin In Evaluating Intestinal Involvement Of Behçet'S Disease

One of the regions of involvement of Behçet's disease (BD), a systematic inflammatory vasculitis with unknown etiology, is the gastrointestinal (GI) tract. Upper GI endoscopy, colonoscopy, and capsule endoscopy are frequently used methods to diagnose the intestinal involvement of BD. The aim of this study was to investigate the role of fecal calprotectin (FC) in the evaluation of intestinal involvement in BD. Material and Method. A total of 30 patients who were diagnosed with BD and had no GI symptoms and 25 individuals in the control group were included in this study. Results. Levels of FC were statistically significantly higher in patients with BD compared to the control group (p < 0.001). The correlation analysis performed including FC and markers of disease activity revealed a positive and statistically significant correlation between FC level and CRP and erythrocyte sedimentation rate (r: 0.255, p < 0.049, and r: 0.404, p < 0.001, resp.). FC levels in patients who were detected to have ulcers in the terminal ileum and colon in the colonoscopic examination were statistically significantly higher compared to the patients with BD without intestinal involvement (p = 0.01). Conclusion. The measurement of FC levels, in patients with BD who are asymptomatic for GI involvement, may be helpful to detect the possible underlying intestinal involvement.PubMedWoSScopu
