Adiponectin and waist circumference as predictors of insulin-resistance in women.

Background And Aims: The initial disturbance of insulin resistance seems to focus on adipose tissue is a dynamic organ involved in many physiological and metabolic processes. Expresses and secretes a variety of active peptides, adipocytokines. To evaluate the prevalence of insulin-resistance in an healthy urban middle age population and to explore the role of adiponectin, inflammatory biomarkers (hs-CRP) and traditional cardiovascular risk factors as predictors of the insulin-resistance state.

Link Conditions for Simplifying Meshes with Embedded Structures.

Interactive visualization applications benefit from simplification techniques that generate good-quality coarse meshes from high-resolution meshes that represent the domain. These meshes often contain interesting substructures, called embedded structures, and it is desirable to preserve the topology of the embedded structures during simplification, in addition to preserving the topology of the domain. This paper describes a proof that link conditions, proposed earlier, are sufficient to ensure that edge contractions preserve the topology of the embedded structures and the domain.

[Reference values and prevalence of lipidic profile alterations in adolescents].

Introduction: Altered lipid metabolism along with other cardiovascular risk factors promotes atherosclerosis at early age, leading to cardiovascular disease development. We aimed to estimate the prevalence of abnormal lipid profle in school adolescents from the city of Posadas, Misiones, Argentina, and describe the distribution of values in an apparently healthy subgroup.

Population And Methods: Descriptive cross-sectional study in a sample of students from 12 to 18 years of age.

[Metabolic syndrome and risk factors associated with life style among adolescents in a city in Argentina, 2005].

Objectives: To determine the prevalence of metabolic syndrome among adolescents in a city in Argentina and to establish its association with certain risk factors linked to life style.

Methods: Cross-sectional study of a representative sample of 532 middle and high school students from 11-20 years of age (mean: 15.3 years; females: 60%) in the city of Posadas, province of Misiones, Argentina, from July-October 2005.

Fracture of the spine, spinal epidural haematoma and spondylitis. Report of one case and review of the literature.

We report the case of a patient suffering from spinal epidural haematoma and thoracic spinal fracture, and from ankylosing spondylitis. Fourteen cases of spinal epidural haematoma in association with ankylosing spondylitis have been reported in the literature, 12 of them at a cervical level. Spinal epidural haematoma found in patients suffering from ankylosing spondylitis share the same clinical picture as other haematomas, the notion of time being the main feature.

[Latent congenital mitral insufficiency caused by an isolated mitral cleft. Diagnosis by two-dimensional echocardiography and pulsed Doppler].

In this paper, the authors report the case of an 8-year-old boy with an isolated slit in his mitral valve, and who did not have a heart murmur detectable either by auscultation or by phonocardiography and who had no symptoms of heart failure. Two-dimensional echocardiography, with a left parasternal direction, in a transversal view revealed the presence of this abnormality of the endocardial leaflets accompanied by an accessory chorda tendina, and this procedure confirmed the absence of hemodynamic percussion. Doppler ultrasonography detected an abnormal turbulent systolic blood flow immediately behind the mitral valve, suggesting a minimal to moderate degree latent regurgitation.
