Are we really seeing the total costs of surgical site infections? A Spanish study.

2007

To identify overall costs generated by surgical site infections (SSI) patients, including indirect costs. A prospective study of case series of patients who have undergone major surgical treatment was undertaken. Patients who suffered SSI were compared with controls (nested case-control design). Centers for Disease Control and Prevention definitions were followed and SSI established. Overall costs and indirect related morbidity/mortality costs were estimated. The study was performed in a general, tertiary hospital (Valencia, Spain) for 4.5 years. Surgical site infections patients were 9.02% of the total people who underwent surgery. Their stays were prolonging by 14 days, and resources were…

Potential role of the neuropeptide CGRP in the induction of differentiation of rat hepatic portal vein wall.

2005

The media of the rat hepatic portal vein is composed of an internal circular muscular layer (CL) and an external longitudinal muscular layer (LL). These two perpendicular layers differentiate progressively from mesenchymal cells within the first month after birth. In this paper, we studied the development of calcitonin gene-related peptide (CGRP) innervation during post-natal differentiation of the vessel. We show that CGRP innervation is already present around the vessel at birth in the future adventitia but far from the lumen of the vessel. Progressively, CGRP immunoreactive fibers reached first LL then CL. CL by itself become only innervated at day 14 after birth. This corresponds to the…

A targeted apoB38.9 mutation in mice is associated with reduced hepatic cholesterol synthesis and enhanced lipid peroxidation.

2006

Familial hypobetalipoproteinemia (FHBL) due to truncation-specifying mutations of apolipoprotein B (apoB), which impair hepatic lipid export in very low-density lipoprotein (VLDL) particles, is associated with fatty liver. In an FHBL-like mouse with the apoB38.9 mutation, fatty liver develops despite reduced hepatic fatty acid synthesis. However, hepatic cholesterol contents in apoB38.9 mice are normal. We found that cholesterogenic enzymes (3-hydroxy-3-methylglutaryl-coenzyme A reductase, sterol-C5-desaturase, and 7-dehydrocholesterol reductase) were consistently downregulated in two separate expression-profiling experiments using a total of 19 mice ( n = 7 each for apob+/+and apob+/38.9, …

Our Definition of Propeller Flaps and Their Classification

2020

AbstractThe term propeller flap was introduced for the first time by Hyakusoku to define an island flap, based on a subcutaneous pedicle hub, that was rotated 90 degrees to correct scar contractures due to burns. With the popularization of perforator flaps, the propeller movement was applied for the first time to a skin island vascularized only by an isolated perforator, and the terms propeller and perforator flap were used together. Thereafter, the surgical technique of propeller flaps evolved and new applications developed. With the “Tokyo consensus,” we proposed a definition and a classification schema for propeller flaps. A propeller flap was defined as an “island flap that reaches the …

Receptor Recognition Sites of Cytokines Are Organized as Exchangeable Modules

1999

Interleukin-6 (IL-6) and ciliary neurotrophic factor (CNTF) are "4-helical bundle" cytokines of the IL-6 type family of neuropoietic and hematopoietic cytokines. IL-6 signals by induction of a gp130 homodimer (e.g. IL-6), whereas CNTF and leukemia inhibitory factor (LIF) signal via a heterodimer of gp130 and LIF receptor (LIFR). Despite binding to the same receptor component (gp130) and a similar protein structure, IL-6 and CNTF share only 6% sequence identity. Using molecular modeling we defined a putative LIFR binding epitope on CNTF that consists of three distinct regions (C-terminal A-helix/N-terminal AB loop, BC loop, C-terminal CD-loop/N-terminal D-helix). A corresponding gp130-bindin…

Post-cesarean necrotizing fasciitis caused by surgical site infection

2017

Necrotizing fasciitis (NF) is a rare, but rapidly progressive, potentially life-threatening soft tissue infection, with an incidence of 0.15-0.55 cases per 100,000 population. the gynecological-obstetric literature describes cases of NF due to surgical site infection (SSi) after cesarean delivery. this article discusses issues in the medicolegal evaluation of NF and the importance of prophylactic procedures, risk management protocols, and prompt diagnosis of this condition. two cases of post-cesarean NF due to SSi are reported. in both cases the responsibility lay with the hospitals and the medical staff owing to failure to adopt adequate SSi prophylaxis and to establish a timely diagnosis …

Laparoendoscopic single-site surgery for the treatment of benign adnexal disease: a prospective trial.

2010

Background. To validate feasibility, efficacy, and safeness of laparoscopic treatment of benign adnexal diseases through a single transumbilical access (LESS) in a prospective series of patients. Methods. A prospective clinical trial including 30 women has been conducted at the Division of Gynecology of Catholic University of Sacred Hearth of Rome. Patients underwent different laparoscopic procedures by LESS utilizing a multiport trocar and conventional straight laparoscopic instrumentation. Intra and perioperative outcome has been reported. Results. Ten mono/bilateral adnexectomies and 20 cystectomies have been performed by LESS approach. Laparoscopic procedures were completed through a si…

Sistema inteligente para protocolizar el diagnóstico de invasión ganglionar en el cáncer de laringe

2002

Laryngeal carcinoma is the most frequent malignant tumour in head and neck. Node invasion is known to be one of the most important prognostic factors. The aim of this study has been to design an intelligent system to perform a diagnostic algorithm of metastasic neck nodes. 122 clinical reports of patients diagnosed of laryngeal carcinoma in our department have been reviewed. The compiled data have been: tumor site, T stage, N stage (clinical, after CT scan and post-surgery). The method used to design the intelligent system has been the ID3, which is able to generate a minimal decision tree. Palpation has been the variable that has given more information about node invasion. CT has proved to…

Acellular dermal matrix in soft tissue reconstruction prior to bone grafting. A case report.

2010

When hard tissue augmentation is scheduled as a part of an oral rehabilitation, prior to the treatment, it is important to assess if the quality of the underlying gingiva at the recipient site can support the bone grafting procedure. The most frequent complication during autologous onlay grafts are wound dehiscences in the recipient site, so the integrity of soft tissues is a basic aspect of successful reconstructive and plastic surgical procedure. Connective tissue grafts can improve the quality and quantity of soft tissue in oral sites where a hard tissue reconstruction is going to take place. However, particularly when large grafts are harvested, the autogenous donor site can present sig…
