An 18-Month Follow-up, Randomized Comparison of Effectiveness and Safety of Two Hyaluronic Acid Fillers for Treatment of Moderate Nasolabial Folds
2016
Hyaluronic acid (HA) filler injection is a popular nonsurgical aesthetic procedure.To compare the effectiveness and safety of 2 hyaluronic acid fillers (HAEC and HARES) for treatment of moderate nasolabial folds (NLFs).This was an evaluator- and subject-blinded split-face study. HAEC or HARES was randomly assigned to the left or right NLF at baseline. Retreatment was performed after 9 months; follow-up extended to 18 months after baseline (9 months after retreatment). Effectiveness assessments included the Wrinkle Severity Rating Scale (WSRS) and subject preference. Safety assessments included adverse events (AEs) and local tolerability symptoms recorded by subjects during 3 weeks after tre…
Intraoperative brain mapping during awake surgery in symptomatic supratentorial cavernomas.
2021
Abstract Background Complete resection of symptomatic supratentorial cavernoma (SCA) and removal of the surrounding gliotic area is recommended to minimize the risk of persistent seizures or (re)bleeding. Surgery of SCA located in an eloquent area, can carry out severe postoperative neurological morbidity. We report a study aimed to assess feasibility, extent of resection and outcome after surgical removal of CA by cortico-subcortical intraoperative brain stimulation (ioBS) in the awake patient. Methods Six patients diagnosed of symptomatic SCA located on an eloquent area and operated on while awake under local anaesthesia ioBS, were included. Preoperative planning included neuropsychologic…
Manual Reaction Times and Brain Dynamics after 'Awake Surgery' of Slow-Growing Tumours Invading the Parietal Area. A Case Report.
2012
International audience; PRIMARY OBJECTIVES: Awake surgeries of slow-growing tumours invading the brain and guided by direct electrical stimulation induce major brain reorganizations accompanied with slight impairments post-operatively. In most cases, these deficits are so slight after a few days that they are often not detectable on classical neuropsychological evaluations. Consequently, this study investigated whether simple visuo-manual reaction time paradigms would sign some level of functional asymmetries between both hemispheres. Importantly, the visual stimulus was located in the saggital plane in order to limit attentional biases and to focus mainly on the inter-hemispheric asymmetry…
Vascular mapping of the face: B-mode and doppler ultrasonography study.
2015
Background To analyze the face vascularization pattern using B-mode and Doppler ultrasonography, and also propose an arterial vessel mapping. Material and Methods The investigation was performed on 20 ultrasonography exams of facial vessels through linear and endocavitary transducers. We analyzed and determined the average values for diameters, peak systolic velocity and resistive index of the following arteries: external carotid, lingual, deep lingual, sublingual, facial, submental, inferior labial, superior labial, angular, maxillary inferior alveolar, mental, buccal, greater palatine, infraorbital, superficial temporal, transverse facial and frontal. Results Data was obtained allowing th…
Intraperitoneal Onlay Mesh Technique for Spigelian Hernia in an Outpatient and Short-Stay Surgery Unit: What's New in Intraperitoneal Meshes?
2018
Spigelian hernia (SH) is a rare entity, but its surgical treatment is essential because of its high complication risk. Laparoscopic approaches have become the option in elective surgery because it has less morbidity and requires a shorter stay. Several laparoscopic techniques have been employed, but there is no gold standard technique for this kind of hernia. We report, in this study, our experience with intraperitoneal onlay mesh (IPOM) repair.Fifteen patients underwent elective surgery for SH between 2008 and 2015 in a Short-Stay Surgical Unit. Laparoscopic IPOM technique was performed in all patients. The technique, epidemiological data, operative findings, hospital stay, morbidity, and …
Laparoscopic ileocecal resection in acute and chronic presentations of Crohn's disease. A single center experience
2017
Introduction The terminal ileum is the most involved tract in Crohn's disease. The obstruction in this location is the most frequent complication. Acute or chronic presentations can occur. Surgery finds a role in the management of chronic strictures and in acute clinical presentations with complications not improving with conservative therapy. Patients and methods We investigate the outcome of patients with obstruction of the ileo-cecal bowel tract laparoscopically managed. It was analyzed the average operative time (OT), the conversion rate and the occurrence of re-operation due to surgical complications. Results 21 patients underwent an ileocecal resection for complicated Crohn's disease …
Monitoring of alphatorquevirus DNA levels for the prediction of immunosuppression-related complications after kidney transplantation
2019
The replication kinetics of nonpathogenic anelloviruses belonging to the Alphatorquevirus genus (such as torque teno virus) might reflect the overall state of posttransplant immunosuppression. We analyzed 221 kidney transplant (KT) recipients in whom plasma alphatorquevirus DNA load was quantified by real-time polymerase chain reaction at baseline and regularly through the first 12 posttransplant months. Study outcomes included posttransplant infection and a composite of opportunistic infection and/or de novo malignancy (immunosuppression-related adverse event [iRAE]). Alphatorquevirus DNA loads at month 1 were higher among patients who subsequently developed posttransplant infection (P = …
A prospective clinical study of polycarboxylate cement in periapical surgery
2011
Objective: To evaluate the clinical efficacy of polycarboxylate cement as retrograde filling material. Design: A prospective clinical study was made of 25 patients subjected to periapical surgery with ultrasound and magnifying loupes, in which polycarboxylate cement was used as retrograde filling material. Measurements were made of the area and diameter of the lesions pre- and postoperatively, and 6 and 12 months after the operation. The apical resection and retrograde filling areas were also measured, and the prognosis following surgery was recorded. Results: A total of 23 patients with 31 apicoectomized teeth were studied (2 patients being lost to follow-up). The mean area of the periapic…
Tumors of the oral cavity : CO2 laser management
2019
Background Cancer of the oral cavity combined with oropharyngeal cancer is the sixth leading cause of death for cancer worldwide. Surgery remains the standard treatment for this disease in early clinical and locally advanced stages. Numerous studies have shown that laser management is useful for premalignant lesions in the oral cavity; however, there is no conclusive evidence that its use is appropriate in cancer of the oral cavity and that results are comparable with traditional surgery. The objective of this study is to determine cancer control after wide local resection with CO2 laser for oral malignant neoplasms. Material and Methods Retrospective study in patients with tumors of the or…
Treatment of chronic mandibular dislocations by eminectomy: follow-up of 10 cases and literature review.
2008
Introduction: Temporomandibular joint (TMJ) dislocation is defined as an excessive forward movement of the condyle beyond the articular eminence, with complete separation of the articular surfaces and fixation in that position. Objectives: To report ten cases treated by eminectomy for chronic mandibular dislocations, to evaluate the results of these surgeries and make a critical review of the literature. Methods: The sample was obtained from the records of the Department of Oral and Maxillofacial Surgery, University of Pernambuco and comprises cases submitted to chronic mandibular dislocation treatment by eminectomy between 2002 and 2007. Pre- and postoperative assessment included a thoroug…
