Long-term comparison of corneal aberration changes after laser in situ keratomileusis: mechanical microkeratome versus femtosecond laser flap creatio…
2010
Purpose To compute and compare visual acuity, refractive outcomes, and anterior corneal aberration changes after myopic laser in situ keratomileusis (LASIK) with flap creation by a mechanical microkeratome and by a femtosecond laser. Setting Private practice refractive surgery center, Valencia, Spain. Design Comparative case series. Methods Patients were assigned to have LASIK flap creation with a mechanical microkeratome (Carriazo-Barraquer) or a femtosecond laser (IntraLase). The Visx S2 excimer laser was used for myopic ablation in all cases. Main outcome measures included uncorrected and corrected distance visual acuities and the defocus equivalent. Higher-order aberrations (HOAs) were …
Long-term metabolic effects in patients with urinary diversion
1998
The use of intestinal segments in genitourinary reconstruction could influence vitamin metabolism and affect the skeletal bone and its mineral content in the long term. In 137 patients, serum levels of the vitamins A, B1, B2, B6, B12, D, and E and of folic acid, bile acid, and ammonia as well as levels of intracorpuscular vitamin B12 and folic acid were examined and a red blood cell count was performed. The patients were divided into three groups (or = 2 years,2 toor = 4 years, and4 years after surgery) as well as into children and adults. In addition, bone mineral density (dual-photon absorptiometry) was measured in 25 patients. Of these, 16 patients were approximately 16.8 years s/p recta…
Treatment of severe von Willebrand disease with a high‐purity von Willebrand factor concentrate (Wilfactin®): a prospective study of 50 patients
2007
Background and objectives: A plasma-derived von Willebrand factor (VWF) concentrate with low factor VIII (FVIII) content was specifically developed to treat von Willebrand disease (VWD). Efficacy and safety were investigated by merging the results of two comparable protocols conducted prospectively in 5 European and 12 French centers. Methods and results: Fifty patients with clinically severe VWD (72% had VWF ristocetin cofactor activity less than 10 IU dL(-1) and 46% had FVIII < 20 IU dL(-1)) were treated with the concentrate as the only therapy, except for clinical situations requiring a priming dose of FVIII to rapidly correct an intrinsic coagulation defect. A total of 139 spontaneous b…
Terminal ligature of inferior thyroid arterhy branches during total thyroidectomy for multinodular goiter is associated with higher postoperative cal…
2010
Purpose: To evaluate the impact of truncal versus terminal branch ligature of the inferior thyroid artery (ITA) on postoperative calcium and PTH plasma levels in patients undergoing total thyroidectomy for multinodular goiter. Methods: A prospective randomized study was performed comparing a group of patients that underwent either truncal ligature of the ITA (group 1) or terminal ligature of ITA branches (group 2). Results: A series of 126 consecutive patients with non-toxic euthyroid multinodular goiter underwent total thyroidectomy. Truncal ligature of the ITA was performed in 63 patients (group 1) and terminal branch ITA ligature in 63 patients (group 2). Postoperative ionized serum calc…
Is laparoscopic approach still a risk factor for postappendectomy intra-abdominal abscess?
2020
Background The impact of laparoscopic appendectomy (LA) on the incidence of intra-abdominal abscess (IAA) remains controversial. We aimed to identify risk factors for postappendectomy IAA and assess the impact of appendectomy approach in postoperative morbidity. Methods A retrospective single-center study including consecutive patients who underwent appendectomy for acute appendicitis between 2015 and 2018 was performed. Demographic, clinical, intraoperative, and perioperative variables were collected. Univariate and multivariate analyses was performed to detect independent risk factors for IAA. Comparison of LA and open appendectomy was conducted, and propensity score model (PSM) was used …
Management of intralabyrinthine schwannomas
2006
Abstract Objectives Our protocol to manage the intralabyrinthine schwannoma (ILS). Methods Retrospective chart review of 7 consecutive patients managed for ILS. Results Five patients underwent surgical removal of the lesions and none experienced significant complications or recurrent disease. One patient refused surgical treatment and was closely followed by serial MRI scans with no signs of tumor growth. One patient is presently managed conservatively due to a good hearing. Conclusions Diagnosis of ILS is based on high resolution MRI scans and should be included in the differential diagnosis of patients investigated for cochleovestibular symptoms. Treatment modality of ILS is controversial…
Endoscopic Treatment of Arachnoid Cysts
2010
Background Surgical treatment of arachnoid cysts remains under debate. Although many authors favor endoscopic techniques, others attribute a higher recurrence rate to the endoscope. Objective The authors report their experience with endoscopic procedures for arachnoid cyst. Methods All pure endoscopic procedures for arachnoid cysts performed by the authors were analyzed. Particular reference was given to surgical complications and patient outcome in relation to cyst location and endoscopic technique. Results Sixty-six endoscopic procedures were performed in 61 patients (mean age, 28 years; range, 23 days to 74 years; 35 males, 26 females). The main presenting symptoms were cephalgia (61%), …
Comparison of 4% articaine with epinephrine (1:100,000) and without epinephrine in inferior alveolar block for tooth extraction: double-blind randomi…
2011
The purpose of this clinical prospective, randomized, double-blind study was to compare the anesthetic efficacy of 4% articaine with epinephrine (1:100,000) and without epinephrine in inferior alveolar nerve block anesthesia for extractions of mandibular teeth.Eighty-eight patients received intraoral inferior alveolar nerve blocks using 4% articaine with 1:100,000 epinephrine (n = 41; group 1) or without epinephrine (n = 47; group 2) for extractions of mandibular teeth. The primary objectives were differences in onset as well as in length of soft tissue anesthesia. The amount of anesthetic solution, need of a second injection, pain while injecting, pain during treatment, postoperative pain,…
Management of naso-septal deformity in childhood: long-term results.
2008
Abstract Objective The classical teaching advocates a conservative approach for children presenting with various naso-septal deformities. It may not be appropriate especially when it causes nasal obstruction to the growing child. This study has two main purposes: to contribute in identifying the correct selection criteria for surgical management of pediatric patients and in selecting the most appropriate surgical technique. Material and method We reviewed a series of 46 cases of post-traumatic septal and naso-septal deformity not managed promptly or with recurrence of nasal deviation, following bones fracture correction alone. The mean follow-up was 10 years. Results Patients with naso-sept…
Early Results of Fissurectomy and Advancement Flap for Resistant Chronic Anal Fissure without Hypertonia of the Internal Anal Sphincter
2010
The aim of this study was to assess the efficacy of fissurectomy with skin advancement flap in healing chronic anal fissures without hypertonia of the internal anal sphincter. Twenty-six consecutive patients who failed healing after well-practiced topical medical therapy were enrolled. Anorectal manometry was performed preoperative and 6 months postoperatively. All patients were treated with fissurectomy and advancement flap through healthy skin tissue. All patients healed completely within 30 days from operation. The intensity and the duration of pain post-defecation was reduced significantly with respect to the preoperative values starting from the first defecation. One patient suffered …
