A systematic approach to the failed plastic surgical reconstruction of the diabetic foot

Plastic reconstruction for diabetic foot wounds must be approached carefully and follow sound micro-surgical principles as it relates to the anatomy of the designated flap chosen for coverage. First, the surgeon always needs to evaluate the local and general conditions of the presenting pathology and patient, respectively when considering a flap for reconstruction. The flap that is chosen is based on the vascularity, location, and size of the defect. Salvage of the failed flap and revisional reconstructive procedures are very challenging. Often, adjunctive therapies such as hyperbaric oxygen, negative pressure wound therapy, vasodilators, and/or vascular surgery is required. In certain case scenarios, such as patients with poor general health and compromised local vascularity in which revisional flap coverage cannot be performed, the above mentioned adjunctive therapies could be used as a primary treatment to potentially salvage a failing flap

Cumulative exposure to air pollution and long term outcomes after first acute myocardial infarction: A population-based cohort study. Objectives and methodology

<p>Abstract</p> <p>Background</p> <p>Cardiovascular disease is a leading cause of morbidity and mortality worldwide and epidemiological studies have consistently shown an increased risk for cardiovascular events in relation to exposure to air pollution. The Israel Study of First Acute Myocardial Infarction was designed to longitudinally assess clinical outcomes, psychosocial adjustment and quality of life in patients hospitalized with myocardial infarction. The current study, by introducing retrospective air pollution data, will examine the association between exposure to air pollution and outcome in myocardial infarction survivors. This report will describe the methods implemented and measures employed. The study specifically aims to examine the relationship between residential exposure to air pollution and long-term risk of recurrent coronary event, heart failure, stroke, cardiac and all-cause death in a geographically defined cohort of patients with myocardial infarction.</p> <p>Methods/Design</p> <p>All 1521 patients aged ≤65 years, admitted with first myocardial infarction between February 1992 and February 1993 to the 8 hospitals serving the population of central Israel, were followed for a median of 13 years. Data were collected on sociodemographic, clinical and environmental factors. Data from air quality monitoring stations will be incorporated retrospectively. Daily measures of air pollution will be summarised, allowing detailed maps to be developed in order to reflect chronic exposure for each participant.</p> <p>Discussion</p> <p>This study addresses some of the gaps in understanding of the prognostic importance of air pollution exposure after myocardial infarction, by allowing a sufficient follow-up period, using a well-defined community cohort, adequately controlling for multiple and multilevel confounding factors and providing extensive data on various outcomes.</p

A randomized controlled trial of two types of in-shoe orthoses in children with flexible excess pronation of the feet

BACKGROUND: Orthoses for children with flexible excess pronation are estimated to cost Australian parents millions of dollars per year; however, there is no high-level evidence that orthoses improve function or reduce pain. METHODS: A randomized parallel, single-blinded, controlled trial of custom-made and ready-made orthoses was conducted in children between the ages of 7 and 11 years with bilateral flexible excess pronation. The diagnosis was based on calcaneal eversion and navicular drop. Outcomes included gross motor proficiency, self-perception, exercise efficiency, and pain. Measurements were taken at baseline, and at 3 and 12 months. Of the 178 children who participated at baseline, 160 continued to the end of the trial. RESULTS: After randomization, baseline characteristics were similar between the three treatment groups (custom-made, ready-made, and control). Statistical modeling demonstrated that although for most outcome measures there were statistically significant trends over time, none of the group comparisons were statistically significant. A sub-group analysis of those presenting with pain found no significant differences at 3 or 12 months. CONCLUSIONS: This study found no evidence to justify the use of in-shoe orthoses in the management of flexible excess foot pronation in children
