Severe third molar complications including death-lessons from 100 cases requiring hospitalization.
2006
Purpose In this study we investigated patients that were hospitalized due to third molar (M3) complications. Specifically we analyzed frequency, age distribution, and outcome with respect to the M3 clinical status. Patients and Methods We set up a prospective cohort study and included 100 subjects admitted for management of acute M3-associated complications. The clinical status of the M3 was defined as 1 ) prophylactic M3 removal, 2 ) therapeutic (nonelective) M3 removal, or 3 ) M3 present at the time of admission. Outcome variables were clinical infection markers (C-reactive protein, leukocyte counts) and economic parameters (treatment costs, length of hospital stay, and days of disability…
Efficacy of a topical gel containing chitosan, chlorhexidine, allantoin and dexpanthenol for pain and inflammation control after third molar surgery …
2020
BACKGROUND: The aim of this study was to evaluate and compare the postoperative effect of a topic gel containing chlorhexidine, chitosan, allantoine and dexpanthenol versus a placebo for pain and inflammation control after third molar surgery. MATERIAL AND METHODS: A gel combining 0.2% chlorhexdine, 0.5% chitosan, 5% dexpanthenol, 0.15% allantoin and 0.01% sodium saccharin was selected for this split mouth randomized controlled and double-blind trial including 36 patients with bilaterally and symmetrically impacted lower third molars. The teeth (n=72) were randomly divided into two groups before surgical removal: control group (CG; in which a placebo was given) and experimental group (EG). …
The effects of a topical gel containing chitosan, 0,2% chlorhexidine, allantoin and despanthenol on the wound healing process subsequent to impacted …
2016
Background Despite efforts to prevent postoperative discomfort, there are still many immediate side effects associated with the surgical extraction of impacted lower third molars. Cicatrization is a physiological process through which the loss of integrity of oral mucosa is recovered and damaged tissues are repaired. Bexident Post (ISDIN, Spain) is a topical gel that contains chitosan, 0.2% chlorhexidine, allantoin and dexpanthenol. While this gel has many clinical indications, there are no published clinical trials evaluating its use in impacted mandibular third molar surgery. This study aims to clinically evaluate the efficacy of a gel containing chitosan, 0.2% chlorhexidine, allantoin an…
AdVEGF165gene transfer increases survival in overdimensioned skin flaps
2004
Background Vascular endothelial growth factor (VEGF) is a key regulator of angiogenesis. VEGF A also plays an important role in wound healing of the skin by promoting angiogenesis and by stimulating blood vessel growth. Therefore we tested the hypothesis that flap survival could be increased by the preoperative injection of AdVEGF165. Methods We studied the effect of AdVEGF165 in an overdimensioned ischemic random-pattern-flap model in the rat (n = 50) with a length-to-width ratio of 4 : 1. VEGF cDNA was administered in two concentrations of 5 × 108 plaque-forming units (pfU) and 1 × 109 pfU using a recombinant adenoviral vector. Recombinant virus was injected subdermally 7, 3 or 0 days pri…
Adenoviral RB2/p130 gene transfer inhibits smooth muscle cell proliferation and prevents restenosis after angioplasty.
1999
Abstract —Smooth muscle cell (SMC) proliferation that results in neointima formation is implicated in the pathogenesis of atherosclerotic plaques and accounts for the high rates of restenosis that occur after percutaneous transluminal coronary angioplasty, a widespread treatment for coronary artery disease. Endothelial lesions trigger intense proliferative signals to the SMCs of the subintima, stimulating their reentry into the cell cycle from a resting G 0 state, resulting in neointima formation and vascular occlusion. Cellular proliferation is negatively controlled by growth-regulatory or tumor-suppressor genes, or both, such as the retinoblastoma gene family members ( RB/p105, p107, RB2…
Evaluation of the healing of precoated vascular dacron prostheses.
1991
Knitted and woven Dacron grafts commercially coated with bovine collagen, gelatin and human albumin were implanted end-to-side between the infrarenal aorta and the bifurcation in 35 growing pigs. Grafts were explanted after 4, 8 and 12 weeks and compared to 6 uncoated knitted prostheses preclotted with blood that served as a control. Uncoated grafts rapidly developed a firmly attached neointima lined with endothelium. Compared with coated grafts the thrombus-free area of uncoated grafts was significantly larger (P less than 0.05). The slow resorption of albumin resulted in a delayed and incomplete neointimal healing and failing graft incorporation. Although the bovine collagen was only mini…

Platelet-rich plasma (PRP) in dental and oral surgery: from the wound healing to bone regeneration
2013
Platelet-rich plasma (PRP) is a new approach to tissue regeneration and it is becoming a valuable adjunct to promote healing in many procedures in dental and oral surgery, especially in aging patients. PRP derives from the centrifugation of the patient's own blood and it contains growth factors that influence wound healing, thereby playing an important role in tissue repairing mechanisms. The use of PRP in surgical practice could have beneficial outcomes, reducing bleeding and enhancing soft tissue healing and bone regeneration. Studies conducted on humans have yielded promising results regarding the application of PRP to many dental and oral surgical procedures (i.e. tooth extractions, per…
Antibiotic Prophylaxis for Thyroid and Parathyroid Surgery: A Systematic Review and Meta-analysis
2020
Objective: Although thyroid and parathyroid surgery is considered a clean procedure with a low incidence of surgical site infections (SSIs), a great number of endocrine surgeons use antibiotic prophylaxis (AP). The aim of this study was to assess whether AP is significantly effective in reducing the incidence of SSIs in this kind of surgery. Data Sources: A systematic literature search was performed with PubMed, Scopus, and ISI–Web of Science. Studies addressing the efficacy of AP in reducing the incidence of SSIs in thyroid and parathyroid surgery were included in the systematic review and meta-analysis. Review Methods: The random effects model was assumed to account for different sources …
Transconjunctival sutureless 25-Gauge versus 20-Gauge standard vitrectomy: correlation between corneal topography and ultrasound biomicroscopy measur…
2009
Purpose: To determine the correlation between corneal shape changes and ultrasound biomicroscopy (UBM) findings at the sclerotomy sites in conventional 20-gauge (G) pars plana vitrectomy (PPV) and 25-G transconjunctival sutureless vitrectomy (TSV) and to compare the effectiveness of the two surgical methods. Design: Prospective, comparative, observational case series. Methods: Sixty consecutive eyes (60 patients) undergoing primary 3-port PPV. Thirty eyes (30 patients, group 20-G) were treated with 20-G standard PPV and 30 eyes (30 patients, group 25-G) with 25-G TSV. We compared healing of the sclerotomy sites in the two groups. We determined the correlation between corneal shape changes (…
