Outcomes of aortic valve repair according to valve morphology and surgical techniques
2012
OBJECTIVES: The aim of this study was to assess the impact of aortic valve morphology and different surgical aortic valve repair techni- ques on long-term clinical outcomes. METHODS: Between February 2003 and May 2010, 216 patients with aortic insufficiency underwent aortic valve repair in our institu- tion. Ages ranged between 26 and 82 years (mean 53 ± 15 years). Aortic valve dysfunctions, according to functional classification, were: type I in 55 patients (25.5%), type II in 126 (58.3%) and type III in 35 (16.2%). Sixty-six patients (27.7%) had a bicuspid valve. Aortic valve repair techniques included sub-commissural plasty in 138 patients, plication in 84, free-edge reinforcement in 80,…
Histological evaluation of bone repair using beta-Tricalcium Phosphate
2010
Objectives: The aim of the present study was to evaluate bone repair in defects induced in the cranium of Wistar rats using ?-tricalcium phosphate. Study Design: In this research, we used 30 rats, randomly distributed in three groups of 10 animals (G1, G2 and G3), corresponding respectively to time of histological evaluation (7, 15 and 30 days). This was a paired study, a defect being induced in the parietal bone on either side of the median sagittal suture of the animals, being the left-hand side the experimental subgroup (filled by biomaterial) and the right control. The histological evaluation was performed by means of light microscopy. The collected data were submitted to the Fisher Exa…
Cranial deformations in an Iron Age population from Münsingen-Rain, Switzerland
2008
The aim of this paper is an examination of cranial fluctuating asymmetry (FA) and deformations in the prehistoric population of Munsingen-Rain (La Tene period, Switzerland). The material consists of 76 skulls. Three cases of craniosynostosis, one scaphocephalic skull with complete obliteration of the sagittal suture and two plagiocephalic skulls were identified. CT scans showed that premature closure of the frontosphenoidal suture caused these plagiocephalies. For three asymmetrically deformed skulls, differential diagnosis indicates torticollis (wry neck). Another four skulls exhibit strongly developed asymmetries of the cranium and mandible, but an aetiological diagnosis was not possible.…
Healthcare associated infection: novel strategies and antimicrobial implants to prevent surgical site infection
2010
This report is based on a Hygienist Panel Meeting held at St Anne's Manor, Wokingham on 24–25 June 2009. The panel agreed that greater use should be made of antiseptics to reduce reliance on antibiotics with their associated risk of antibiotic resistance. When choosing an antiseptic for clinical use, the Biocompatibility Index, which considers both the microbiocidal activity and any cytotoxic effects of an antiseptic agent, was considered to be a useful tool. The need for longer and more proactive post-discharge surveillance of surgical patients was also agreed to be a priority, especially given the current growth of day-case surgery. The introduction of surgical safety checklists, such as…
Beyond the functional matrix hypothesis: a network null model of human skull growth for the formation of bone articulations.
2014
Craniofacial sutures and synchondroses form the boundaries among bones in the human skull, providing functional, developmental and evolutionary information. Bone articulations in the skull arise due to interactions between genetic regulatory mechanisms and epigenetic factors such as functional matrices (soft tissues and cranial cavities), which mediate bone growth. These matrices are largely acknowledged for their influence on shaping the bones of the skull; however, it is not fully understood to what extent functional matrices mediate the formation of bone articulations. Aiming to identify whether or not functional matrices are key developmental factors guiding the formation of bone articu…
Role of Ovarian Suspension in Preventing Postsurgical Ovarian Adhesions in Patients with Stage III-IV Pelvic Endometriosis: A Systematic Review.
2018
Endometriosis is a benign complex gynecological condition with high morbidity that affects women of reproductive age. Pelvic adhesion formation represents a serious clinical challenge in the management of patients with endometriosis. Several interventions have been proposed over the last few years aiming to reduce post-operative ovarian adhesions formation. The aim of this study is to summarize the evidence of the efficacy of ovarian suspension in the prevention of post-operative ovarian adhesions formation in women undergoing laparoscopic surgery for stage III-IV endometriosis. The research was conducted using electronic databases. A review of the abstracts of all references retrieved from…
The colovescical fistula in diverticular disease: Laparoscopic approach in two different cases
2020
Highlights • The colovescical fistula is one of the complications of diverticular disease. • It can cause typical symptoms like pneumaturia and fecaluria affecting the quality of life and sometimes leading to death, usually secondary to sepsis. • We studied two patients with clinical, radiological and endoscopic diagnosis of colovescical fistula as a consequence of diverticular disease. • We performed a totally laparoscopic treatment with colonic resection and closure of the fistula with intracorporeal sutures. • The presence of a colovescical fistula significantly increases the difficult of the laparoscopic colonic resection.
Effects of polyglecaprone 25, silk and catgut suture materials on oral mucosa wound healing in diabetic rats: An evaluation of nitric oxide dynamics
2009
Guvenc, Tolga/0000-0003-1468-3415; BAS, BURCU/0000-0003-0593-3400 WOS: 000278232100022 PubMed: 20038896 Objectives: The purpose of this study is to investigate the effects of monocryl (Polyglecaprone 25), silk and catgut suture materials on wound healing in diabetic rats and to evaluate NO (nitric oxide) dynamics. Study desing: Fourty-eight male Wistar-Albino rats weighting 220-270 g were used in this study. The rats were categorized into 2 groups, as control group (n=24) and streptozotocin (STZ) induced diabetic group (n=24). For each group, incision wounds were created on the inner cheeck mucosa of the animals and wounds were closed primarily with three different types of sutures. These m…
Endograft connector technique to treat popliteal artery aneurysm in a morbid obese patient.
2015
Surgical repair of popliteal artery aneurysm in morbid obese patients poses additional challenges. We report a morbid obese patient who had a 59 mm right popliteal artery aneurysm which was successfully treated with the endograft connector technique. This technique was used to perform the distal anastomosis of the below-knee femoro-popliteal bypass. A 10 mm Dacron graft was used as a main graft bypass and an 11 mm/10 cm stentgraft as endograft connector. Following the respective tunnel of the Dacron graft, an end-to-side proximal anastomosis was performed at distal femoral artery. The aneurysm exclusion was obtained through a proximal and a distal ligation. Postoperative duplex showed adeq…
Suture Materials: Do They Affect Fistula and Stricture Rates in Flap Urethroplasties?
2003
<i>Introduction:</i> The effect of suture materials on urethroplasty complications is debated. Indeed, materials with a delayed absorption might either reduce the incidence of fistulas by ensuring a prolonged approximation of neo-urethral edges or increase the risk of urethral strictures due to a prolonged tissue reaction during suture absorption. We retrospectively evaluated the role of suture materials in the complication rate of urethroplasty procedures performed in our institution over a 10-year period. <i>Patients and Methods:</i> Three hundred and thirty-six boys undergoing a flap procedure (parameatal based, preputial tube, or onlay preputial flap) for hypospa…
