The present study aims to assess the effects of cigarette smoke inhalation and/or coffee consumption on bone formation and osseous integration of a dense hydroxyapatite (DHA) implant in rats. For this study, 20 male rats were divided into four groups (n = 5): CT (control) group, CE (coffee) group, CI (cigarette) group and CC (coffee + cigarette) group.(More)
OBJECTIVE To characterize structural changes and the metabolic profile of foot muscles and correlate them with diabetic neuropathy measurements using phosphorus-31 ((31)P) rapid acquisition with relaxation enhancement (RARE) magnetic resonance imaging (MRI). RESEARCH DESIGN AND METHODS We studied 12 control subjects, 9 non-neuropathic diabetic patients,(More)
OBJECTIVE Localized low-level mechanical or electrical noise can significantly enhance tactile sensitivity in healthy young subjects and older adults. This phenomenon is termed stochastic resonance (SR). In this study, we examined the effect of SR on vibratory and tactile sensation in patients with moderate to severe diabetic peripheral neuropathy.

OBJECTIVE Foot ulceration is a serious complication of diabetes, and new techniques that can predict wound healing may prove very helpful. We tested the ability of medical hyperspectral technology (HT), a novel diagnostic scanning technique that can quantify tissue oxy- and deoxyhemoglobin to predict diabetic foot ulcer healing. RESEARCH DESIGN AND(More)
BACKGROUND Healing is a complex process that involves cellular and biochemical events. Several medicines have been used in order to shorten healing time and avoid aesthetic damage. OBJECTIVE to verify the topical effect of ascorbic acid for the healing of rats' skin wounds through the number of macrophages, new vessels and fibroblast verifications in the(More)
OBJECTIVE To examine the effect of a 12-week daily treatment with 160 mg of valsartan, an angiotensin II receptor blocker, on the microcirculation and macrocirculation of type 2 diabetic patients (T2DM) and healthy subjects. METHODS This was a prospective, randomized, double-blind, placebo-controlled crossover study. Thirteen T2DM with no severe(More)
Alcohol consumption compromises bone tissue, and thus may either impair or stop the fixation and maintenance of osseointegrated implants. To evaluate the effects of 5% and 15% ethanol on bone neoformation around porous hydroxiapatite implants. Fifteen rats were separated into 3 groups of 5 animals each: control (CT); 5% alcohol (A); and 15% alcohol (AA).(More)
Animals kept as pets may be considered sentinels for environmental factors to which humans could be exposed. Olfactory and respiratory epithelia are directly subjected to airborne factors, which could cause DNA lesions, and the alkaline comet assay is considered a reliable tool for the assessment of DNA damage. The objective of this work is to evaluate the(More)
Background: Foot ulceration (DFU) is a serious complication of diabetes and new techniques that can predict wound healing may prove very helpful. We tested the ability of Medical Hyperspectral Technology (HT), a novel diagnostic scanning technique which can quantify tissue oxyand deoxyhemoglobin, to predict DFU healing. Methods: Ten T1DM patients with 21(More)
The authors call attention to the work of Trueta on open fractures and to the fact that, even today, his principles are followed all over the world. Today, such fractures are immobilized with external skeletal fixation instead of plaster casts. The results are presented of 71 patients with severe open fractures of the tibia who were treated by external(More)
