Assessment of cardiovascular alterations and catecholamines serum concentration after oral surgery in patients receiving local anesthetics with epinephrine: a randomized, blind, controlled clinical trial.

Objectives: A randomized controlled clinical trial was developed to evaluate the cardiovascular effects of local anesthetics with vasoconstrictors (LAVC) in healthy and hypertensive patients undergoing teeth extraction with lidocaine 2% with epinephrine 1:100,000.

Materials And Methods: Twenty patients were divided into control (CG - normotensive patients) and experimental groups (EG - hypertensive patients). The variables analyzed were heart rate (HR), oxygen saturation (SO2), systolic and diastolic blood pressure (SBP and DBP), serum catecholamine concentration (dopamine, epinephrine, and norepinephrine), ventricular and supraventricular extrasystoles (VES and SVES respectively), and ST segment depression.

Tongue measurements and pharyngeal residue in amyotrophic lateral sclerosis.

We aimed to analyze the relationship between tongue measurements and vallecular residue in patients with amyotrophic lateral sclerosis (ALS). Twenty-one patients with ALS were assessed for posterior maximum tongue isometric pressure (PMTIP) and posterior tongue isometric endurance (PTIE) by the Iowa Oral Performance Instrument; vallecular residue after 10 ml of moderately thickened consistency by Fiberoptic Endoscopic Evaluation of Swallowing; and tongue thickness (TT) by ultrasonography. PMTIP, PTIE and TT were decreased compared with the reference values for healthy individuals and were not different between patients with and without vallecular residue.

Epidemiologic study of anisometropia in students of Natal, Brazil.

Purpose: To perform an epidemiologic study in students in Natal/Brazil, with relation to refractional anisometropia, evaluating criteria such as: gender, age, and association with strabismus and amblyopia.

Methods: A study of 1,024 students randomly selected from several districts of Natal/Brazil was undertaken by the Department of Ophthalmology of the Federal University of Rio Grande do Norte (UFRN), observing the following criteria of > or =2 spherical or cylindrical diopter refractional anisometropia relating it to sex, age, association with strabismus, amblyopia and anisometropia classification.

Results: We found a prevalence of 2% (N=21) anisometropia in the students.
