Introduction: Soft tissue reconstruction after vulvar, vaginal, or anal cancer resection poses a formidable task for reconstructive surgeons because of the functional, locational, and cosmetic importance of this region. Although numerous flaps have been designed for vulvar reconstruction, each has its disadvantages. Methods: The authors introduce the local fasciocutaneous infragluteal (FCI) flap for vulvar and vaginal reconstruction after tumor resection, vaginal scar obliteration, and vulvar ulceration in 15 patients operated on between 1999 and 2007. The FCI flap is supplied by the cutaneous branch of the descending branch of the inferior gluteal artery. The sensory supply of this flap comes from side branches of the posterior cutaneous nerve of the thigh. A total of 17 flaps were performed in 15 patients. Results: Except for one, all flaps survived. One flap necrosis occurred because of false postoperative position with compression and tension to the vascular pedicle. In the remaining patients, we found one local cancer recurrence with necessity of a second flap from the contralateral side. The patients report satisfaction with reconstruction, without one having pain at donor site and recurrent vaginal ulceration. Conclusions: This article discusses the expanding indications of this versatile flap and the operative technique of the local FCI flap for reconstruction of vulvar and partial vaginal defects. It can be raised in different volume and dimension out of possible irradiated area with an inconspicuous scar. Copyright © 2012 by IGCS and ESGO.

Fibrosis is the production of excessive amounts of connective tissue, i.e., scar formation, in the course of reactive and reparative processes. Fibrosis develops as a consequence of various underlying diseases and presents a major diagnostically and therapeutically unsolved problem. In this review, we postulate that fibrosis is always a sequela of inflammatory processes and that the many different causes of fibrosis all channel into the same final stereotypical pathways. During the inflammatory phase, both innate and adaptive immune mechanisms are operative. This concept is exemplified by fibrotic diseases that develop as a consequence of tissue damage, primary inflammatory diseases, fibrotic alterations induced by foreign body implants, "spontaneous" fibrosis, and tumor-associated fibrotic changes. © Copyright 2013 by Annual Reviews.

For ruptured human cerebral aneurysms endovascular embolization has become an equivalent alternative to aneurysm clipping.(1) However, large clinical trials have shown disappointing long-term results with unacceptable high rates of aneurysm recanalization and delayed aneurysm rupture.(2) To overcome these problems, animal experimental studies are crucial for the development of better endovascular devices.(3-5) Several animal models in rats, rabbits, canines and swine are available.(6-8) Comparisons of the different animal models showed the superiority of the rabbit model with regard to hemodynamics and comparability of the coagulation system and cost-effectiveness.(9-11) The venous pouch arterial bifurcation model in rabbits is formed by a venous pouch sutured into an artificially created true bifurcation of both common carotid arteries (CCA). The main advantage of this model are true bifurcational hemodynamics.(12) The major drawbacks are the sofar high microsurgical technical demands and high morbidity and mortality rates of up to 50%.(13) These limitations have resulted in less frequent use of this aneurysm model in the recent years. These shortcomings could be overcome with improved surgical procedures and modified peri- and postoperative analgetic management and anticoagulation.(14-16) Our techniques reported in this paper demonstrate this optimized technique for microsurgical creation of arterial bifurcation aneurysms.

Aims Pre-treatment with clopidogrel results in a reduction of ischaemic events in non-ST-elevation acute coronary syndromes. Data on upstream clopidogrel in the setting of primary percutaneous coronary intervention (PCI) are limited. The aim of this study was to investigate whether clopidogrel loading before arrival at the PCI centre may result in an improved outcome of primary PCI for ST-elevation myocardial infarction (STEMI). Methods and results In a multicentre registry of acute PCI, 5955 patients undergoing primary PCI in Austria between January 2005 and December 2009 were prospectively enrolled. The patients consisted of two groups, a clopidogrel pre-treatment group (n = 1635 patients) receiving clopidogrel before arrival at the PCI centre and a peri-interventional clopidogrel group (n = 4320 patients) receiving clopidogrel at a later stage. Multiple logistic regression analysis including major confounding factors stratified by the participating centres was applied to investigate the effect of pre-treatment with clopidogrel on the in-hospital mortality. Additionally, two subgroups, with or without the use of GP IIb/IIIa antagonist therapy in the catheterization laboratory, were analysed. On univariate analysis, clopidogrel pre-treatment was associated with a reduced in-hospital mortality (3.4 vs. 6.1, P< 0.01) after primary PCI. On multivariate analysis, clopidogrel pre-treatment remained an independent predictor of in-hospital mortality [odds ratio (OR) 0.60, 95 confidence interval (CI) 0.350.99; P = 0.048], especially in patients receiving additional GP IIb/IIIa antagonist therapy in the catheterization laboratory (OR 0.40, 95 CI 0.190.83; P = 0.01). Conclusion Clopidogrel pre-treatment before arrival at the PCI centre is associated with reduced mortality in a real world setting of primary PCI. These results strongly support the recommendation of clopidogrel treatment 'as soon as possible' in patients with STEMI undergoing pimary PCI. © 2011 The Author.

Single nucleotide polymorphisms (SNPs) in IL28B and serum levels of interferon γ inducible protein 10 (IP-10) predict outcomes of antiviral therapy in patients with chronic hepatitis C. We associated IL28B SNPs rs12979860 and rs8099917, along with serum levels of IP-10, with outcomes of patients with acute hepatitis C (AHC). We studied 120 patients with AHC (64 male; 37 ± 16 years old) and 96 healthy individuals (controls). The IL28B SNPs rs12979860 and rs8099917 were detected using real-time polymerase chain reaction; serum concentrations of IP-10 were measured by enzyme-linked immunosorbent assays of 62 patients with AHC. Hepatitis C virus was cleared spontaneously from 59 patients (49.2%). The IL28B rs12979860 C/C genotype was more frequent among patients with AHC than controls (62.5% vs 39.6%; P <.001) and among patients with spontaneous clearance than those without (74.6% vs 51.7%; P =.02) (positive predictive value, 60.3%). Patients with IL28B rs12979860 C/C more frequently developed jaundice (53.2% vs 27.6%; P =.022) than carriers of the T allele. The median level of IP-10 was lower among patients with AHC and spontaneous clearance (764 [1132470] pg/mL) than those without spontaneous clearance (1481 [1414412] pg/mL; P =.006). Based on receiver operating characteristic analysis, 540 pg/mL IP-10 was set as the cutoff for patients most likely to have spontaneous clearance (positive predictive value, 71.4%; negative predictive value, 65.9%). Including data on IP-10 levels increased the ability of the IL28B rs12979860 C/C to identify patients most likely to have spontaneous clearance (83% of those who had an IP-10 level <540 pg/mL and 32% who had an IP-10 level >540 pg/mL) (P <.01). The combination of serum level of IP-10 and SNPs in IL28B can identify patients with AHC who are most likely to undergo spontaneous clearance and those in need of early antiviral therapy. © 2012 AGA Institute.
