Treatment of malar and midfacial fractures with osteoconductive forged unsintered hydroxyapatite and poly-L-lactide composite internal fixation devic…
2013
Purpose To evaluate the internal fixation of malar and midfacial fractures, long-term results, and biocompatibility of osteoconductive internal fixation devices composed of a forged composite of unsintered hydroxyapatite and poly-L-lactide (F-u-HA/PLLA). Materials and Methods From January 2006 to June 2010, 29 patients (24 males and 5 females; age 33 ± 15 years) were included in the present prospective study. The fracture type was malar in 24 patients, midfacial in 5, isolated orbital floor blowout in 2, and frontal sinus, cranial base in 2 patients. The fractures were fixed with internal fixation devices; these were plates and screws composed of F-u-HA/PLLA. The 24 patients with malar frac…
Tracheal Ceramic Rings for Tracheomalacia: A Review After 17 Years
2007
Background: Despite different support techniques, the surgical management of tracheomalacia is still a challenging problem. Satisfactory results after internal stenting are above 80%, whereas, when performing external stenting using biocompatible ceramic rings, results are reported at over 90%. Objective: The purpose of this study was to examine the efficiency of surgical treatment in patients with segmentary tracheomalacia using external ceramic ring grafts. Methods: In this retrospective study, we collected data from 12 patients who underwent surgery during the last 17 years for symptomatic segmentary tracheomalacia by use of biocompatible aluminum-oxide ceramic rings. All except one pati…
Posterior chamber phakic intraocular lenses to correct high myopia: A comparative study between Staar and Adatomed models
2001
ABSTRACT PURPOSE: To determine the feasibility of using posterior chamber phakic intraocular lenses (PIOLs) to treat high myopia, comparing two different models, Staar and Adatomed. METHODS: Twenty-four eyes from 12 patients were studied prospectively. A phakic Staar IOL was implanted in one eye of each patient, and the other eye received a phakic Adatomed IOL. Patients with uveitis or ocular trauma prior to ocular surgery, diabetic retinopathy, or capsular pseudoexfoliation were excluded. The mean preoperative spherical equivalent refraction was -16.00 ± 5.05 D for the Staar group and -15.39 ± 2.83 D for the Adatomed group. Average follow-up was 32.4 months (range, 19 to 46 mo) for the Ada…
Why have I failed? Why have I passed? A comparison of students’ causal attributions in second language acquisition (A1–B2 levels)
2019
Background Previous literature highlights the importance of causal attributions in achievement and motivation. However, the studies about causal attributions in second language acquisition (SLA) are limited and scarce. Aims This study was designed to determine the frequency of successful and unsuccessful activities per English level and to compare the causal attributions (explanations of outcomes) on successful and failure authentic tasks undertaken in the context of learning English as a foreign language (EFL) acquisition in an Official School of Languages (OSL). Sample To this aim, 407 native Spanish students from levels A1 (n = 111), A2 (n = 113), B1 (n = 98), and B2 (n = 85) in OSL part…
Otoneurological management of petrous apex cholesterol granuloma
2009
Objective: The aim of the study is to review the management of petrous apex cholesterol granuloma. The surgical approaches for drainage or total removal and the wait and see policy were analyzed, and outcomes were evaluated. Methods: Retrospective charts of 27 patients managed for petrous apex cholesterol granuloma with a minimum follow-up of 12 months were analyzed in a quartenary skull base center. Presenting symptoms and signs were recorded, and radiologic imaging was evaluated. Management options included wait and see policy and surgery by several approaches. Results: The mean age of patients affected by the lesion was 38.8 years. The mean follow-up was 56.7 months. Patients complained …
Endophthalmitis following penetrating eye injuries
1997
Postinjury endophthalmitis is the eye infection with the worst prognosis. A retrospective 9-year study was made of penetrating eye injuries, with an analysis of the incidence of infection and its relation to the type of wound and the presence of intraocular foreign bodies. There were 403 cases of penetrating eye injury; of these, 233 affected the cornea and 170 involved the posterior pole. Intraocular foreign bodies were present in 40 cases. Endophthalmitis developed in 4.2% of cases (17/403), and was more common in patients with posterior pole involvement (7%) than in purely corneal trauma (2.1%) (p = 0.03, Chi-square). Infection was in turn more frequent in the presence of intraocular for…
Treatment of Idiopathic Varicoceles by Transfemoral Testicular Vein Occlusion
1981
Percutaneous transfemoral occlusion of the testicular vein is a new alternative in the treatment of idiopathic varicocele. Embolization with the Gianturco coil was done on 27 patients. The occlusion was performed immediately after diagnostic phlebography. The results of followup for 1 year are available for 18 patients. In 1 patient the coil had to be removed because of persistent pain, although cause and effect could not be proved. Two patients had a recurrence. The urographic findings were normal 1 year after embolization. No dislocation of the foreign body was observed. Two patients reported that their wives were pregnant.
Retrospective analysis of management of ingested foreign bodies and food impactions in emergency endoscopic setting in adults.
2016
Background: Ingestion of foreign bodies and food impaction represent the second most common endoscopic emergency after bleeding. The aim of this paper is to report the management and the outcomes in 67 patients admitted for suspected ingestion of foreign body between December 2012 and December 2014. Methods: This retrospective study was conducted at Palermo University Hospitals, Italy, over a 2-year period. We reviewed patients’ database (age, sex, type of foreign body and its anatomical location, treatments, and outcomes as complications, success rates, and mortalities). Results: Foreign bodies were found in all of our 67 patients. Almost all were found in the stomach and lower esophagus (…
Impact of Different Texture of Polypropylene Mesh on the Inflammatory Response
2008
Over the past decade, hernia surgery has undergone a considerable transformation with the use of prosthetic materials. The most used polypropylene meshes induce a rapid acute inflammatory response followed by chronic foreign body reaction. Many factors influence this response such as density, size, physical characteristics, different texture and porosity of each biomaterial. The aim of this study is to assess whether the implant of monofilament or multifilament meshes, in the inguinal hernioplasty, determine a different inflammatory response. Thirty-two male patients were included in the study and were randomly divided into two groups. In the first group (MO) inguinal hernioplasty was perf…
Tension-free hernia repair is associated with an increase in inflammatory response markers against the mesh.
2000
Abstract Background: The purpose of this study was to evaluate the involvement of inflammatory mediators in patients undergoing Lichtenstein tension-free hernioplasty (LH) using polypropylene prosthetic materials or conventional Bassini hernia repair (BH). Methods: Thirty patients male with unilateral inguinal hernia without complications or recurrence were included in this study. Randomly, patients underwent LH or BH. Peripheral venous bloods samples were collected 24 hours prior to surgery and then 6, 24, 48 and 168 hours postoperatively. Results: We present evidences that LH patients showed a higher increased serum level of fibrinogen, C-reactive protein, alpha-1-antitrypsin, and interle…
