Comparison of Preoperative Nd:YAG Laser Anterior Capsulotomy Versus Two-Stage Curvilinear Capsulorhexis in Phacoemulsification of White Intumescent Cataracts

BACKGROUND AND OBJECTIVE: To compare the results of preoperative Nd:YAG laser anterior capsulotomy versus two-stage continuous curvilinear capsulorhexis (CCC) in phacoemulsification of eyes with white intumescent cataracts and liquefied cortex. PATIENTS AND METHODS: Twenty-three eyes with white intumescent cataract were consecutively randomized for phacoemulsification with preoperative Nd:YAG laser anterior capsulotomy (group 1, n = 11) or two-stage CCC (group 2, n = 12) procedures. Intraoperative findings and postoperative outcomes were compared using the nonparametric tests. RESULTS: Postoperative Visual acuity, mean surgical time, mean effective phacoemulsification time, and frequency of complications were not significantly different between the two groups (P > .05). Two cases in each group were converted to the extracapsular technique. Excluding these four patients, surgical time was shorter In group 1 (P = .017). CONCLUSION: Preoperative Nd:YAG laser anterior capsulotomy is a safe technique in decompressing the capsular bag before phacoemulsification of white intumescent cataracts with liquefied cortex.

Effect of Multiple Cranial Burr Hole Surgery on Prevention of Recurrent Ischemic Attacks in Children with Moyamoya Disease

Moyamoya disease (MMD) is an uncommon cerebrovascular disorder characterized by progressive stenosis of the terminal portion of the internal carotid artery and its main branches. Direct and indirect bypass techniques have been devised with the aim of promoting neoangiogenesis. The current study aimed to investigate the role of multiple cranial burr hole (MCBH) operations in the prevention of cerebral ischemic attacks in children with MMD. Seven children suffering from progressive MMD were submitted to the MCBH and arachnoid opening technique. Ten to 20 burr holes were drilled in the fronto-temporo-parieto-occipital area of each hemisphere in each patient, depending on the site and extent of the disease. All patients were evaluated pre- and postoperatively by means of Barthel index (BI), CT, MR, angio-MR, and angiography. Patients had no recurrence of ischemic attacks postoperatively. Neoangiogenesis was observed in both hemispheres. One patient developed a persistent subdural collection after surgery, thus requiring placement of a subdural-peritoneal shunt. Postoperative BI was statistically significantly improved (P = 0.02). This report suggests that MCBH for revascularization in MMD is a simple procedure with a relatively low risk of complications and effective for preventing cerebral ischemic attacks in children. In addition, MCBH may be placed as an adjunct to other treatments for MMD.

Dioctophyma renale in a dog: Clinical diagnosis and surgical treatment

This Study reports a case of parasitism by the giant kidney worm, Dioctophyma renale, diagnosed in the right kidney of a domestic (log An adult female German Shepherd was attended with clinical history of prostration and hyporexia. The hemogram showed changes compatible with an inflammatory process, for that reason, an abdominal ultrasound was requested. Ultrasound image suggested the presence of D renale in the right kidney The diagnosis was confirmed after urinalysis due to the presence of dioclophymas ova in the urinary sediment. Surgical treatment was made and the animal had an excellent recovery after the nephrectomy was performed Generally. in almost all cases, parasitism by D renale in domestic dogs is a necropsy finding, nevertheless imaging techniques as sonography and laboratorial exams as urinalysis have been proven to be important tools to achieve diagnosis. The purpose of this study is to report a case of parasitism by D renale where diagnosis and treatment were made in time to allow the patient`s recovery (C) 2009 Elsevier B V All rights reserved.

A comparison of post-thaw results between embryos arising from intracytoplasmic sperm injection using surgically retrieved or ejaculated spermatozoa

Objective: To study the effect of freeze-thaw on embryos derived from intracytoplasmic sperm injection (ICSI) using surgically retrieved and ejaculated spermatozoa. Design: Retrospective study. Setting: Private IVF center. Patient(s): Three hundred eighty-three patients undergoing frozen-thawed ET cycles. Intervention(s): Testicular sperm aspiration (TESA) or percutaneous epididymal sperm aspiration (PESA) were the sperm surgical retrieval methods used for ICSI. Embryos resulting from ICSI using Surgically retrieved and ejaculated spermatozoa were frozen, thawed, and transferred. Main Outcome Measure(s): Post-thaw survival, implantation, and pregnancy rates. Result(s): No differences were found between the ejaculated sperm and TESA/PESA groups in terms of post-thaw survival rate (68.4% vs. 66.1%, respectively), pregnancy rate (20.1% vs. 16.1%), and implantation rate (10.6% vs. 12.7%). Similar results were found for those variables when comparing TESA and PESA groups. Conclusion(s): Cleavage embryos arising from ICSI cycles using testicular and epididymal spermatozoa can be frozen with survival, pregnancy,and implantation rates comparable to those obtained with ejaculated spermatozoa.

Nasopharyngeal angiofibroma. surgical approach using a transoral Le Fort I osteotomy following embolization: a case report

Nasopharyngeal angiofibroma (NA) is a rare vascular benign nonencapsulated neoplasm, characterized by local aggressiveness and destructive potential, typically diagnosed in adolescent males. We report a case of NA affecting a 15-year-old male that presented with a persistent nasal obstruction and epistaxis with 1 year of evolution. Clinical and radiological patterns pointed out a differential diagnosis of NA. Arteriography demonstrates the vascular support of the tumor and evinces the embolization of the internal maxillary artery. The surgical approach was procedure by Le Fort I osteotomy exposing the tumor and promoting easy access for posterior removal. The surgery was carried out without hemorrhagic problems. The maxilla was fixed in the original position with 4 L-shape plaques. Histopathological findings supported the diagnosis of NA. The patient presented after 8 months of postoperative follow-up, without clinical signs of recurrence or residual tumor and without palatal or maxillary teeth paresthesia.
