Efficacy and safety of decompressive craniectomy with non-suture duraplasty in patients with traumatic brain injury.
2020
AbstractBackgroundDecompressive craniectomy is an important surgical treatment for patients with severe traumatic brain injury (TBI). Several reports have been published on the efficacy of non-watertight sutures in duraplasty performed in decompressive craniectomy. This study aims to evaluate the effectiveness of dura closure without sutures (non-suture duraplasty) in decompressive craniectomy for TBI.MethodsOne hundred and six patients were enrolled at a single trauma center between January 2017 and December 2018. We retrospectively collected the data and classified the patients into non-suture and suture duraplasty craniectomy groups. We compared the characteristics of patients and their …
Deep seroma after incisional hernia repair. Case reports and review of the literature.
2015
Wound-related complications are common after incisional hernia repair with mesh; seroma formation is the most frequent problem. The formation of a deep seroma has been rarely reported in the literature.In one year, September 2012-2013, 136 patients underwent surgery for incisional hernia repair, both elective and urgent.The following complications were observed: one dislocation of polypropylene prosthesis, a massive relapsed seroma and two deep seromas described in this article. A 63- years-old female underwent open incisional hernia repair with an intraperitoneal PTFE patch. She developed recurrent seroma under the mesh drained percutaneously, and finally the prosthesis was removed. A 72- …
Complications associated with the ball, bar and locator attachments for implant-supported overdentures
2010
Background: The purpose of this clinical study was to evaluate the complications associated with the different attachments used in implant-supported overdentures, including prosthetic problems and implant failures. A comparison of ball, bar and Locator (Zest Anchors, Inc, homepage, Escondido, CA, USA) attachments, in completely edentulous patients with two, three or four implants, was conducted. Material and methods: A total of 36 edentulous patients (20 female, 16 male) with a mean age of 66.3 years, were enrolled in the study. The patients were treated with 95 implants, for the prosthetic restoration of the maxilla or the mandible. The mean follow-up time was 41.17 months. Prosthetic comp…
Silicone-Silver Penile Prosthesis: Description, Operative Approach and Results
1980
A silicone penile prosthesis in which silver wires are embedded to allow for voluntary bending of the penis for urination and resting position and for straightening for intercourse is described. The implantation is done via a hemicircular incision on the dorsum of the penis in the sulcus coronarius. Buck's fascia is identified and opened, and the corpora are dilated up to 30F. After the exact length is determined with a special sizer the prosthesis is slipped into each corpus cavernosum. The advantage of this approach is the optimal insertion of the prosthesis distal to the sulcus coronarius, thereby preventing kinking of the glans during intercourse. Our experiences with the implantation i…
The Impact of Endoscopic Ultrasound and Computed Tomography on the TNM Staging of Early Cancer in Barrett's Esophagus
2006
Computed tomography (CT) and endoscopic ultrasound (EUS) are part of the regular staging protocol in esophageal cancer. The value of the two methods was assessed in patients with early cancer in Barrett's esophagus.One hundred consecutive patients (median age 64 yr, interquartile range [IQR] 58-72) with suspected early cancer in Barrett's esophagus who were referred to our hospital for endoscopic therapy were prospectively included in a standardized staging program with upper gastrointestinal endoscopy, EUS (7.5 MHz in all cases plus 12.5 or 20 MHz for elevated and/or depressed lesions), CT of the chest and upper abdomen, and abdominal ultrasonography. The results were summarized in accorda…
Virtual temporal bone: an interactive 3-dimensional learning aid for cranial base surgery.
2009
OBJECTIVE: We have developed an interactive virtual model of the temporal bone for the training and teaching of cranial base surgery. METHODS: The virtual model was based on the tomographic data of the Visible Human Project. The male Visible Human's computed tomographic data were volumetrically reconstructed as virtual bone tissue, and the individual photographic slices provided the basis for segmentation of the middle and inner ear structures, cranial nerves, vessels, and brainstem. These structures were created by using outlining and tube editing tools, allowing structural modeling either directly on the basis of the photographic data or according to information from textbooks and cadaver…
Description of dynamic shared knowledge: an exploratory study during a competitive team sports interaction.
2011
This exploratory case study describes the sharedness of knowledge within a basketball team (nine players) and how it changes during an official match. To determine how knowledge is mobilised in an actual game situation, the data were collected and processed following course-of-action theory (Theureau 2003). The results were used to characterise the contents of the shared knowledge (i.e. regarding teammate characteristics, team functioning, opponent characteristics, opposing team functioning and game conditions) and to identify the characteristic types of change: (a) the reinforcement of a previous element of shared knowledge; (b) the invalidation of an element of shared knowledge; (c) fragm…
Extended right colectomy, left colectomy, or segmental left colectomy for splenic flexure carcinomas: a European multicenter propensity score matchin…
2020
Background: The surgical resection of the splenic flexure carcinoma (SFC) is challenging and the optimal surgical procedure for SFCs remains a matter of debate. The present study aimed to compare in a multicenter European sample of patients the short- and long-term outcomes of extended right (ERC) vs. left (LC) vs. segmental left colectomy (SLC) for SFCs. Methods: This retrospective multicenter study analyzed the surgical and oncological outcomes of SFC patients undergoing elective curative intent surgery between 2000 and 2018. Descriptive and exploratory analyses were first conducted on the whole sample. Outcomes of the different procedures (ERC vs. LC vs. SLC) were then compared using pro…
Cardiovascular and ocular safety of α1-adrenoceptor antagonists in the treatment of male lower urinary tract symptoms
2014
α1-Adrenoceptor antagonists (α-blockers) represent first-line drug treatment for male lower urinary tract symptoms. Their adverse events (AEs) include asthenia, dizziness, nasal congestion, arterial (orthostatic) hypotension and intraoperative floppy iris syndrome (IFIS).This report focuses on cardiovascular and ocular AEs of α-blockers as related to their mechanism of action and subtype selectivity.The incidence of hypotension differs between α-blockers. It is greatest with doxazosin or terazosin, but others including tamsulosin can also lead to hypotension especially upon treatment initiation. Concomitant antihypertensive medication increases the incidence of hypotension with some α-block…
When should cuckolded males care for extra-pair offspring?
2012
In socially monogamous species with bi-parental care, males suffer reduced reproductive success if their mate engages in extra-pair copulations (EPCs). One might therefore expect that males should refuse to care for a brood if they can detect that an EPC has occurred. Here, we use a game-theory model to study male brood care in the face of EPCs in a cooperatively breeding species in which offspring help to raise their (half-) siblings in their parents' next breeding attempt. We show that under certain conditions males are selected to care even for broods completely unrelated to themselves. This counterintuitive result arises through a form of pseudo-reciprocity, whereby surviving extra-pair…
