Prevention of ventricular catheter obstruction and slit ventricle syndrome by the prophylactic use of the Integra antisiphon device in shunt therapy …
2010
Object This 25-year follow-up study was performed on 120 children with hypertensive hydrocephalus to evaluate the influence of the early prophylactic implantation of the Integra antisiphon device (ASD, Integra Neurosciences Ltd.) on the rate of proximal shunt obstructions and the frequency of symptomatic slit ventricle syndrome (SVS). The adaptability of the ASD to growth, proper positioning of the ASD as a necessity for its successful performance, and the 3 phases of SVS development are discussed. Method Since 1978, the ASD has consistently been implanted either at the time of primary shunt insertion (66 neonates, mean follow-up 11 years) or during revisions of preexisting shunts (54 chil…
The Penile Plication Procedure: An Alternative Method for Straightening Penile Deviation
1991
AbstractThe number of reported cases of congenital and acquired penile deviation is evidently increasing. We describe our experience with the penile plication procedure, which we used to treat 40 patients with penile deviation. Postoperatively, all patients regained the ability for sexual intercourse, with potency remaining unimpaired. Of the patients 96% were completely satisfied with the result of the operation. Sustained complications have not been observed. To avoid major trauma the surgical intervention should not include removal of ellipsoids from the penile tunica albuginea as proposed by Nesbit. Since the penile plication method produces equally good results in terms of performance …
Characterization of the effect of intracorneal ring segment in corneal ectasia after laser refractive surgery
2018
Purpose: To evaluate the visual, refractive, topographic, pachymetric, and biomechanical outcomes after intracorneal ring segment implantation in corneas with post-LASIK ectasia. Methods: Retrospective longitudinal study enrolling 26 eyes of 22 patients with post-LASIK ectasia and undergoing intracorneal ring segment implantation (KeraRing®, Mediphacos) using a 60-kHz femtosecond laser (IntraLase®, IntraLase Corp.) for corneal tunnelization. Visual, refractive, anterior, and posterior corneal topographic (Pentacam HR, Oculus), pachymetric, and corneal biomechanical changes (Ocular response Analyzer, Reichert) were evaluated during a 12-month follow-up. Vector analysis of astigmatic changes …
Decompression/Stabilization of the Metastatic Spine: Cotrel-Dubousset-Lnstrumentation in 50 Patients Jan
1993
50 patients with metastatic disease of the spine underwent dorsal decompression and stabilization with the Cotrel-Dubousset-Instrumentation from 1987 to 1991. Indications for surgical treatment were neurologic deficit, spinal instability, and/or pain resistant to medical or radiation treatment. No external orthotics were used postoperatively. Pain was relieved dramatically in 45 patients. Among 25 patients suffering from neurologic deficit preoperatively, 13 improved, 15 remained unchanged, whereas 2 developed an incomplete, transient paraplegia. 15 (7) patients were alive after 1 (2) years. Postoperative complications were frequent, but there were only 2 failures of the stabilization devic…
Clinical follow-up after surgery of lumbar disc prolapses. A critical analysis.
1990
A retrospective clinical study was made on 987 patients with lumbar disc disease treated by discectomy. All patients had been operated on in the Department of Neurosurgery (University-Hospital Mainz). 545 patients were males, and 442 females (1.2:1). Patients in the 4th decade of life were affected most often (33.5%). Perioperative complications occurred in 5.4%, with discitis as the single major complication (1.9%). 83% of all patients who underwent discectomy could return to their normal occupation.
Results of an Adaptive Surgical Approach for Managing Late Onset Hypotony After Trabeculectomy With Mitomycin C.
2018
OBJECTIVES The objective of this study is to investigate the results of an adaptive approach of bleb revision surgery for late onset hypotony after trabeculectomy with mitomycin C because of bleb leakage and/or scleral melting. METHODS A total of 29 eyes of 27 patients, aged 63.8±11.7 years with hypotony maculopathy [intraocular pressure (IOP), ≤6 mm Hg] because of late onset bleb leakage and/or scleral melting after trabeculectomy with mitomycin C in which minimally invasive transconjunctival suturing of the scleral flap was impossible were enrolled in this retrospective interventional case series. External bleb leakage was seen in 16 eyes, 11 eyes suffered from scleral melting. Because of…
Endothelial study of iris-claw phakic lens: four year follow-up.
1998
Abstract Purpose: To study quantitative and morphometric endothelial changes in phakic eyes implanted with the Worst iris-claw lens to correct high myopia. Setting: Department of Ophthalmology, University Hospital “La Fe”, Valencia, Spain. Material and Methods: This retrospective study involved 111 phakic eyes (73 patients) implanted with the Worst iris-claw lens. Noncontact specular microscopy and computer-assisted analysis was performed preoperatively and 6 months and 1, 2, 3, and 4 years postoperatively. Results: The mean cell loss was 3.85% at 6 months, 6.59% at 1 year, 9.22% at 2 years, 11.68% at 3 years, and 13.42% at 4 years. At 2 years, the hexagonality and coefficient variation in …
Revisional bariatric surgery due to failure of the initial technique: 25 years of experience in a specialized Unit of Obesity Surgery in Spain.
2019
Abstract Objectives To evaluate the effectiveness of conversion surgery in a bariatric surgery unit with 25 years of experience. Method Retrospective observational study of patients with type II obesity or higher who were reoperated by means of conversion surgery due to weight regain, residual body mass index (BMI) >35 kg/m2 or Results A total of 112 patients were included, with a mean age of 40.2 years, who initially underwent vertical banded gastroplasty (VBG) (32.1%), gastric banding (GB) (23.2%), Roux-en-Y gastric bypass (RYGB) (21.4%) and sleeve gastrectomy (SG) (23.2%). The conversion techniques, with a median time between the two surgeries of 70 months, included: RYGB, SG, one-anasto…
Predicting the failure in distal femur fractures.
2018
Abstract Introduction The incidence of nonunion after fractures of the distal femur is up to 6%. The distal femoral nonunion is a disabling disease that needs complex steps in his treatment. Aim of our study is to find predicting factors of non-unions. Materials and methods We retrospectively analyzed 116 cases of distal femoral fractures and 20 cases of non-unions. In both surgeries we analyzed: accuracy of reduction, stability of fixation, hardware used, residual medial or lateral bone defect, use of autologous or heterologous bone grafts. Results Malreduction, particularly axial defect, associated with unbalanced fixation, and a medial cortical bone defect of greater or lesser extent wer…
Impact of antenatal glucocorticoid therapy and risk of preterm delivery on intelligence in term-born children
2015
Context: Women at risk of preterm delivery are routinely treated with synthetic glucocorticoids (sGCs). Although this therapy substantially reduces neonatal morbidity, concerns remain whether sGC excess may disrupt neurodevelopmental trajectories underlying cognitive functioning. Objective: The present study is the first to disentangle direct effects of antenatal sGC treatment on possible long-term cognitive disadvantages from those of pregnancy complications and prematurity. Design, Setting, and Participants: This cross-sectional study included a mixed-sex cohort of 222 term-born children (aged 6–11 years) consisting of three groups: children of mothers admitted to hospital for threatening…
