The purpose of this study is to prospectively analyze the incidence of occult lateral neck metastasis (LNM) and to elucidate the factors that predict LNM in papillary thyroid carcinoma (PTC) with central neck metastasis (CNM) by performing prophylactic selective lateral neck dissection (SND).
The purpose of this study is to determine whether inhalation of Bimosiamose is safe and effective in the treatment of patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD)
The investigators primary outcome measure was the clinically important change in diagnostic accuracy and physical examination in the morphine vs. placebo group. After follow up information was obtained and patients data were recorded on the SPSS data chart, two blinded coauthors (general surgeon and emergency physician) determined the clinically important diagnostic accuracy and change in physical examination. They firstly defined clinically important diagnostic errors, as any disagreement between the preliminary and final diagnosis that might be expected to have adverse effect on the patient's general status. If coauthors decided an instance of diagnostic error as clinically important, this was coded "diagnostic discordance" for statistical analysis. While the preliminary diagnosis was determined as accurate or not different from the final diagnosis, this was coded "diagnostic accuracy" for statistical analysis. Secondary outcome measures included the need for rescue drugs at 30 minutes, the presence of at least one adverse event, demographic features and final diagnosis of the patients.
The hypothesis of this study is that a chronic program of physical strength training, associates to effects of low level laser therapy (LLLT) can, possibly, provide changes in genic expression of muscle and to promote an enhancement of anaerobic muscle performance in humans.
The aims of the Skin Product Assessment Research study were to (1) develop an infrastructure and process for industry-sponsored, Plastic Surgery Educational Foundation (PSEF) research in facial aesthetic surgery and (2) test the research process by comparing outcomes of the Obagi Nu-Derm System (ODNS) and conventional therapy as treatment adjuncts in ablative facial resurfacing.
This study will evaluate the effectiveness of Acoustic Radiation Force Impulse (ARFI)- Imaging compared to Transient Elastography (FibroScan) in differentiating liver fibrosis in patients with chronic hepatitis C. Patients who are scheduled to have a liver biopsy will also undergo ARFI and FibroScan testing. The liver biopsy will be used as the reference method. The target sample size is 433.
Human immunodeficiency virus (HIV) infection has been associated with a variety of cardiovascular diseases. Even most industrialised countries exhibit a growing and aging population of HIV-infected patients in the majority treated with antiretroviral drugs, the investigators still do not know much about the impact of cardiovascular diseases in this group of patients. The present study is an ongoing trial that was conducted as a prospective and multicentre survey, being schemed to analyse the frequency and clinical course of cardiac disorders in HIV-infected patients.
Reduction in vitamin D levels has been reported in subjects with recent onset type 1 diabetes. Several studies suggest that vitamin D supplementation in early childhood decreases the risk of developing type 1 diabetes, therefore vitamin D deficiency might play a role in the disease pathogenesis. We investigated whether the supplementation of the active form of vitamin D (calcitriol) in subjects with recent-onset type 1 diabetes can protect residual beta cell function evaluated by C peptide and improve glycaemic control as evaluated by HbA1c and insulin requirement. Thirty-four subjects (age range 11-35 years, median 18 years) with recent-onset type 1 diabetes (<12 weeks duration) and high basal C-peptide >0.25 nmol/l were randomized in a double-blind trial to calcitriol (the active form of vitamin D, 1.25-dihydroxyvitamin D3 [1,25-(OH)2D3] ) at the dose of 0.25 ug/day or placebo, and followed up for 2 years.
Immune dysregulations, including cytokines and chemokines secretions occurs in alcoholic liver disease. Serum levels and liver expression of CCL2 are increased in patients with alcoholic hepatitis but the role of this chemokine in the pathogenesis of alcoholic liver disease is nevertheless unknown. The aim of the study is to analyze plasma level and liver expression of CCL2 and their relation with liver disease severity and inflammatory infiltrate in our cohort of alcoholic patients. We studied also the association between -2518 CCL2 polymorphism and the severity of alcoholic liver disease.
