The relationship between testosterone levels, the metabolic syndrome (by two criteria), and insulin resistance in a population of men with organic erectile dysfunction.

Introduction: Erectile dysfunction (ED) in men increases with age, as does cardiovascular disease (CVD). Major risk factors of CVD are similar to ED, including insulin resistance (IR) and metabolic syndrome (MS). Hypogonadism has been associated with MS and IR in general populations.

Incidence of metabolic syndrome and insulin resistance in a population with organic erectile dysfunction.

Introduction: Advanced age in men is accompanied by an increased prevalence of cardiovascular disease (CVD) and erectile dysfunction (ED). Prior studies revealed that 56% of an ED population have asymptomatic myocardial ischemia, 75% of men with CAD have symptoms of ED, and 91% of our ED patients have cardiovascular risks.

Aim: Because metabolic syndrome (MS) and insulin resistance (IR) are both predictors of CVD, we wished to evaluate these parameters in our population.

The economic cost of squamous cell cancer of the head and neck: findings from linked SEER-Medicare data.

Objective: To evaluate the excess mortality, resource use, and costs associated with squamous cell carcinoma of the head and neck (SCCHN) among elderly Medicare beneficiaries.

Design: Retrospective cohort analysis using data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute and Medicare claims.

Subjects: Study cohorts included patients aged 65 years and older who were newly diagnosed as having SCCHN in a SEER registry between 1991 and 1993 (N = 4536) and controls matched 1:1 by age and sex.

Improvement in erectile function in men with organic erectile dysfunction by correction of elevated cholesterol levels: a clinical observation.

Purpose: We determined that use of a statin drug to lower cholesterol would improve erectile function in men who have hypercholesterolemia as the only risk factor for erectile dysfunction (ED).

Materials And Methods: A total of 18 men were determined to have increased cholesterol as the only risk factor for ED by history, system review, physical examination and laboratory analysis. Nine of these men agreed to participate in the study.

Decreased free testosterone and dehydroepiandrosterone-sulfate (DHEA-S) levels in women with decreased libido.

A prior study has shown that premenopausal women could have decreased testosterone levels and still have regular menstrual cycles (Guay, 2001). Since ovarian function in such women was normal, the question of a possible adrenal dysfunction causing androgen deficiency was considered. If this was true, the question then arose as to whether the same defect could be seen in postmenopausal women.
