Stereoacuity After Refractive Lens Exchange With AcrySof ReSTOR Intraocular Lens Implantation
2009
Purpose: To evaluate stereoacuity before and after refractive lens exchange (RLE) with AcrySof ReSTOR intraocular lens (IOL) implantation. Methods: Stereoacuity was measured using the Titmus stereotest at 40 cm under photopic conditions (85 cd/m 2 ) before and after RLE with bilateral AcrySof ReSTOR Natural (SN60D3 model) implantation in 30 hyperopic eyes of presbyopes with low astigmatism (⩽1.00 diopter [D]). Stereoacuity measurements after implantation were compared with those found before surgery. Results: Stereoacuity was unchanged after RLE with pseudoaccommodative IOL implantation. In this population of non-cataractous hyperopes with excellent preoperative stereoacuity (46.42±1.36 se…
Ultrasonographic mound height as predictor of vesicoureteral reflux resolution after endoscopic treatment in children
2016
Purpose: Endoscopic dextranomer/hyaluronic acid copolymer (Dx/HA) injection is a safe and efficacious treatment option for vesicoureteral reflux (VUR) in children. Endoscopic appearance, hydrodistention and amount of injected Dx/HA have been demonstrated not to be reliable predictors of outcome. Aim of this study was to evaluate Dx/HA mounds on ultrasound scans (US) and find out any eventual correlation with reflux resolution. Methods: We selected patients treated with endoscopic injection for moderate to high VUR, renal scaring or repeated infections under antibiotic prophylaxis. Success was defined by absence of VUR at control 3. months after surgery; at 3. months we also measured mound h…
Intraoperative ultrasound-assisted approach for endoscopic treatment of vesicoureteral reflux in children
2017
Purpose Despite minimal invasiveness and high success rate, guidelines still prescribe voiding Cystourethrogram (VCUG) after endoscopic treatment for vesicoureteral reflux (VUR) in children. The aim of this paper was to analyze whether intraoperative ultrasound (IO-US) could improve surgical accuracy and perioperative counseling, thus potentially decreasing the need for postoperative VCUG. Methods We selected children treated for moderate to high grade VUR, renal scarring or repeated infections under antibiotic prophylaxis from January to December 2015. Endoscopic injection was combined with IO-US to detect optimal needle placement and to guide mound formation. IO-US findings were compared …
Laparoscopic resection of an epiphrenic diverticulum of the esophagus
2000
Diverticulectomy of epiphrenic diverticula of the esophagus is conventionally performed via left thoracotomy. We report the case of a 57-year-old man who presented with an epiphrenic diverticulum that was resected using a transperitoneal laparoscopic technique.
Multifocal intraocular lenses for unilateral cataract in children.
2009
Purpose To evaluate the implantation of apodized diffractive multifocal intraocular lenses (IOLs) in children with unilateral cataract. Setting Ophthalmology Service, Hospital Clinico Lozano Blesa, Zaragoza, Spain. Design Prospective clinical study. Methods Five children between 4 and 6 years of age with unilateral cataract had cataract extraction and implantation of an apodized diffractive multifocal IOL (AcrySof Restor SN60D3). Phacoaspiration was accompanied by posterior capsulorhexis followed by an anterior vitrectomy. Uncorrected distance (UDVA), corrected distance (CDVA), and corrected near (CNVA) visual acuities; binocular function using the Worth 4-dot test and the TNO stereotest; a…
Laparoscopic drainage of liver abscess: case report and literature review.
2013
Aim To evaluate the safety and efficacy of the minimally invasive surgical approach (laparoscopic drainage) of liver abscesses in selected cases. Case report Male, 58 years old, from a rural area, presented with epigastric abdominal pain, fever, weight loss, loss of appetite, a palpable mass in the epigastrium and neutrophilic leukocytosis. CT revealed a complex multiloculated liver abscess in segments 2-3. Systemic antibiotic therapy alone was ineffective; percutaneous drainage was excluded due to the characteristics of the lesion. Result Given the complexity of the lesion, a laparoscopic approach was chosen involving complete drainage of the abscess, debridement and irrigation; the cavity…
Potential Effect of Antiplatelet and Anticoagulant Therapy on the Timing of the Diagnosis of Bladder Cancer
2016
Abstract Background The most common presenting symptom of bladder cancer (BCa) is hematuria. The present study was designed to define whether patients taking antiplatelet and/or anticoagulant drugs might experience hematuria at an earlier stage or grade of BCa. Patients and Methods The data from 1532 consecutive patients who presented to the emergency unit of our institute from 2004 to 2012 because of gross hematuria as a single symptom were evaluated. Patients (n = 227) with a further diagnosis of BCa were included in our study. For the purpose of the present study, patients were divided into 2 groups: patients receiving antiplatelet or anticoagulant therapy (AAT) (group 1) and patients no…
Permanence of Modifications in Oral Microcirculation in Ex-Smokers.
2019
Background: The aim of this study was to assess the long-term effects of smoking and to investigate the permanence of this damage to the oral microcirculation. Material/Methods: We recruited 75 patients and divided them into 3 groups: group 1 was composed of 25 healthy non-smokers, group 2 was composed of 25 healthy current smokers, and group 3 was composed of 25 healthy ex-smokers. Video-capillaroscopic examination was performed on all patients. The video-capillaroscopic investigation was performed on patients in sitting position, always with the same light source, at the same room temperature (23°C), in the morning, with the same operator (GAS), and was repeated many times for every area …
Prospective, randomized, single-center trial comparing 3 different 10F plastic stents in malignant mid and distal bile duct strictures.
2003
Abstract Background: The aim of this study was to determine whether patency rates differ with respect to the material, design, and surface texture of 3 different plastic stents. Methods: A total of 120 patients (median age 70.5 years; interquartile range 62-78 years) with malignant mid or distal bile duct strictures, seen between March 1996 and May 1999, were prospectively randomized to receive a 10F polyurethane stent, a Teflon Tannenbaum stent, or a hydrophilic hydromer-coated polyurethane stent. The primary study outcome measure was the interval between stent insertion and the first episode of clogging (or the presence of jaundice at death without stent exchange). All 3 types of stent we…
Noninvasive respiratory muscle aids during PEG placement in ALS patients with severe ventilatory impairment.
2010
Abstract Although no clear recommendations are given about when percutaneous endoscopic gastrostomy (PEG) should be placed in amyotrophic lateral sclerosis (ALS) patients, some experts underline the risk of respiratory complications when patients had severe ventilatory muscle impairment (SVMI). Aim To evaluate the efficacy of noninvasive ventilation (NIV) and mechanically assisted cough (MAC) to avoid respiratory complications related to PEG placement in ALS patients with SVMI. Material and methods Prospective study including ALS patients who had chosen to have PEG placement timed by swallowing dysfunction with the aid of NIV and MAC if needed. PEG was carried out under volume-cycled NIV th…
