OBJECTIVE To retrospectively review the clinical case records of patients with idiopathic vocal cord palsies (VCPs) for the presence of preexisting or subsequent development of neurological disease, including multiple sclerosis, motor neuron disease, myasthenia gravis, cerebrovascular disease, and Guillain-Barré syndrome. DESIGN Retrospective case review of all patients with VCP presenting se...

Tourette syndrome (TS) is characterized by multiple motor tics plus one or more vocal (phonic) tics, which characteristically wax and wane. It can no longer be considered the rare and bizarre syndrome that it was once thought to be. The concepts surrounding TS, and our understanding of it, are also becoming increasingly complex and, in some individuals, TS is now recognized to be associated wit...

Oxidative stress (OS) refers to the imbalance between the generation of reactive oxygen species (ROS) and the ability to scavenge these ROS by endogenous antioxidant systems, where ROS overwhelms the antioxidant capacity. Excessive presence of ROS results in irreversible damage to cell membranes, DNA, and other cellular structures by oxidizing lipids, proteins, and nucleic acids. Oxidative stre...

OBJECTIVE To determine the prevalence of common mental disorders (CMD) and evaluate their association with living conditions and occupational organization. METHODS A cross-sectional survey of a random sample of private households was carried out in Olinda, Brazil, in 1993. The sample consisted of 621 adults aged 15 years or over and the participants were interviewed using the Self-Reporting Q...

The association of coronary sclerosis with a disturbance of lipid metabolism is now fairly generally recognized. The cholesterol of the atherosclerotic plaque is derived, at least in part, from the circulating cholesterol (Biggs et al., 1952). At present the only objective measure of such a disturbance in the living subject is analysis of the circulating lipids. Previously it has been shown tha...

the geometry of a system of second order differential equations is the geometry of a semispray, which is a globally defined vector field on tm. the metrizability of a given semispray is of special importance. in this paper, the metric associated with the semispray s is applied in order to study some types of foliations on the tangent bundle which are compatible with sode structure. indeed, suff...

OBJECTIVE To assess the prevalence of gingival bleeding, calculus and periodontal pockets among 18-year-old males. In addition, to verify whether these conditions are associated with years of education and family income. METHODS A cross sectional survey was carried out. A representative sample of 18-year-old males living in Florianópolis, Brazil, was selected from the Brazilian Army applicant...

Background The data for this study comes from the Queensland Linked Data Set [7] for the 1996/1997 financial year. The data set contains de-identified individual-level linked data from hospital admission records, Medicare Benefits Scheme claims (MBS) and Pharmaceutical Benefits claims (PBS). Population figures are based on 1996 census data by the Australian Bureau of Statistics (ABS 1996 Census...

A compact description of coordinated muscle activity is provided by the factorization of electromyographic (EMG) signals. With the use of this approach, it has consistently been shown that multimuscle activity during human locomotion can be accounted for by four to five modules, each one comprised of a basic pattern timed at a different phase of gait cycle and the weighting coefficients of syne...

Introduction. The purpose of this study was to identify significant associations between asthma diagnosis, comorbid conditions, and social problems in children. Method. This study explored data collected in a unique, regional survey of children's health in north Texas originally administered in 2009 to a random sample of 21,530 households with children from 0 to 14 years of age. Descriptive sta...
