Surgical outcomes of Cerebellopontine angle tumors in 50 cases

Introduction: To report our experience with a large series of surgical procedures for removal of cerebellopontine angle (CPA) tumors using different approaches. Materials and Methods: This was a retrospective analysis of 50 patients (mean age, 49 years) with CPA tumors (predominantly acoustic neuroma) who underwent surgical removal using appropriate techniques (principally a translabyrinthine approach) during a 4-year period. Results: One death occurred during this study. There were nine cases (18) of cerebrospinal fluid leak, and five patients (10) were diagnosed as having bacterial meningitis. Complete gross tumor removal was not achieved in four patients (8). Facial nerve function as measured by the House Brackmann system was recorded in all patients 1 year following surgery: 32 had a score of 1 or 2; 26 had a score of 3 or 4; and 8 had a score of 5 or 6. Other complications included four cases of wound infection. Conclusion: The translabyrinthine approach was predominantly used in our series of CPA tumors, and complication rates were comparable with other large case series

An investigation on Vibrionaceae family of bacteria as probiotic factors in shrimp culture

We investigated the effects of Vibrionaceae family of bacteria as probiotics in the process of growth and survival rate of shrimp during propagation stages. Bacterial flora were extracted from seawater, culture farms, shrimp culture farms and sludge of private propagation farms. Different bacteria such as Vibrio alginolyticus (serotype 1-4), Vibrio splendidus I, Vibrio fluvialis II, Vibrio anguillarum I, Vibrio costicul, Vibrio vulnificaus, Vibrio nereis, Vibrio camplbelli, Vibrio natriegens, Vibrio proteolyticus, Vibrio plegius II ,Vibrio fischeri, Aeromonas hydrophila, Aeromonas schuberti, Aeromonas salmonisida, Aeromonas veronii were isolated, identified and lyophilized. These bacteria were used in different experiments on shrimp life cycle stages while the shrimps were being fed on live food such as Chaetoceros, Skeletonema and Tetraselmis algae. Vibrio alginolyticus (serotype 1) with 107 cells/ml increased proliferation of Tetraselmis sp to 71 % in 6 days compared to the control experiment. Also Vibrio alginolyticus (serotype 4) with 105 cells/in' increased Tetraselmis sp. production to 389% in 6 days compared to control. Vibrio splendidus I was also found to be able to increase shrimp fork length in postlarvae stage 3 up to 23% as compared to control. Vibrio alginolyticus and Vibrio fischeri increased survival, fork lenght and body weight of green tiger shrimp in postlarvae stage significantly (P<0.05)

Occult laryngeal foreign body mimicking normal thyroid cartilage

Introduction: Foreign body aspiration is common especially in children. The absence of history of choking does not rule out the diagnosis. Diagnosis required high index of suspicion. Case Presentation: Undiagnosed foreign body aspiration mostly occurs in bronchial airway rather than larynx and can cause severe complications. In this article, we report a silent laryngeal foreign body aspiration to show that careful history taking and accurate evaluation of radiography are important factors for diagnosis. Conclusions: The single most significant factor leading to detect of tracheobronchial foreign body aspiration is a high index of suspicion; this case highlights the possibility of a foreign body in the airway in patients who presents with a recent onset of chronic respiratory complaints. © 2015, Trauma Monthly

Optimum management of warmwater fish farms stocking, capacity determination, growth rate and brood stock managements and harvesting

This study was conducted to codify the guideline and indexes of optimal management in warm-water fish farms to attain sustainable aquaculture which they are population density, species diversity, brood stock'smanagements, capacity determination, growth and harvesting managements in cultural ponds. As results, these guideline and indexes were codifies for these fish farms and propagation centers. It's obviously that these sustainable patterns can be used for improving of permanent development for this aquacultural industry

Aquaculture code of conduct and mechanization management

In this report rules and focal points about code of conduct for cold water farm, warm water establishment, mechanization management and oxygen generators are collected and discussed. One of the most important point difference between aquaculture engineering with mechanization. Mechanization is improvement of management level from ancient to better by some special tools but aquaculture engineering can do by any vessel in every management

Giant cell reparative granuloma of nasal cavity, a case report

Giant cell reparative granuloma (GCRG) is an unusual, nonneoplastic lesion affecting maxillary and mandibular bones. GCRG of the nasal cavity is exceedingly rare. To the best of our knowledge only few of such cases have been previously reported. Being a soft fleshy lesion of bone, it tends to have a benign course, not aggressive and it often recurs following incomplete excision. We report the case of a man with a GCRG of nasal cavity. We discuss the clinical presentation, differential diagnosis, histological evaluation and appearance on computed tomography and MRI. © 2009

Delayed laryngotracheal reconstruction with Titanium plate: Report of 10 cases

Background: Subglottic stenosis is congenital or acquired narrowing of subglottic area. The management of subglottic stenosis is still a serious surgical challenge. Although different surgical techniques are accomplished to manage the condition, no standard treatment has been presented yet. Study Design: Titanium mesh was used in the reconstruction of the anterior laryngotracheal wall in 10 tracheostomized patients with laryngotracheal stenosis because of prolonged intubation. The anterior laryngotracheal wall was split, followed by excision of scar tissue. After several weeks, in a second-stage performance, the titanium plate was fixed at the split edges. Results: Finally, all the patients were decanulated. However, one patient developed respiratory distress because of granulation tissue and underwent a second trial of decanulation. In one patient, the titanium plate extruded

Repair of large nasal septal perforation with titanium membrane:: Report of 10 cases

Objective: The aim of the study was to study a new treatment to repair large nasal septal perforation with medical titanium membrane. Method: Ten patients with septal perforation underwent repair with open rhinoplasty approach using titanium membrane. Results: The perforation of nasal septum in 10 patients was closed satisfactorily. During our follow-up period (mean, 1 year), the titanium membrane was mucosalized, and this technique led to persistent closing of perforation. Conclusion: Repair of septal perforation with titanium membrane yields excellent results. © 2010 Elsevier Inc. All rights reserved
