The association between residential pesticide use and cutaneous melanoma.

Occupational pesticide exposure has been linked to cutaneous melanoma in epidemiological studies. We studied the association between cutaneous melanoma and the residential use of pesticides. This is a case-control study of cutaneous melanoma (287 incident cases; 299 controls).

A glutamine insertion in the 1A alpha helical domain of the keratin 4 gene in a familial case of white sponge nevus.

White Sponge Nevus (WSN) is a rare, autosomal dominant disorder that predominantly affects noncornified stratified squamous epithelia. Clinically, it is characterized by the presence of soft, white, and "spongy" plaques in the oral mucosa. The characteristic histopathologic features are epithelial thickening, parakeratosis, and vacuolization of the suprabasal layer of oral epithelial keratinocytes.

Predictors of referral to cardiac rehabilitation and cardiac exercise self-efficacy.

Cardiac rehabilitation (CR) has known benefits after myocardial infarction (MI) or coronary artery bypass surgery (CABG). Yet, only a small percentage of patients are referred for outpatient CR after hospital discharge. This study investigates patient characteristics related to referral to CR and cardiac exercise self-efficacy, a salient predictor of health behavior change and maintenance.

Counseling for physical activity: what primary-care physicians should know.

In Connecticut, 22.1% of the adult population report no physical activity other than activities of daily living. Primary care physicians can play a vital role in the flight against a sedentary lifestyle.

Effects of oral and intravenous rehydration on ratings of perceived exertion and thirst.

The purpose of this investigation was to compare the effects of oral and intravenous saline rehydration on differentiated ratings of perceived exertion (RPE) and thirst. Eight men underwent three randomly assigned rehydration treatments following a 2- to 4-h exercise-induced dehydration bout to reduce body weight by 4%. Treatments included 0.

Concentric and eccentric isokinetic lower extremity strength in persons with multiple sclerosis.

This study was supported by the Levine-Rubenstein MS Research Fund and The Rehabilitation Research and Development Service of the U.S. Department of Veterans Affairs.

Middle age male distance runners: physiological and psychological profiles.

This study investigated 4 research questions addressing exercise capabilities and psychological characteristics of middle-age (30 to 50 years) male runners. Subjects provided an extensive running history, completed the Multidimensional Anger Inventory, completed the Myers-Briggs Type Indicator, and performed a treadmill running test to volitional exhaustion. Another aspect of the study compared anticipatory and posttest reactions to the treadmill test experience to actual test results.

The threshold for myocardial ischemia varies in patients with coronary artery disease depending on the exercise protocol.

It is generally accepted that angina pectoris and, presumably, myocardial ischemia occur at a fixed heart rate-systolic blood pressure product in a given patient. This concept of a fixed threshold has recently been challenged. To evaluate the effects of varying exercise intensity on the ischemic threshold, 33 patients with coronary artery disease and provokable myocardial ischemia, documented by thallium-201 myocardial perfusion imaging, underwent two exercise tests 2 to 7 days apart.

The Effects of Upper Body Resistance Training on Prepubescent Children.

To assess the effects of a group resistance exercise program on prepubescent children, an experimental group of boys (n= 26) and girls (n= 24), with a mean age of 8.4 ± 0.5 years, participated in 12 weeks of school based training.

The effect of differential training on isokinetic muscular endurance during acute thermally induced hypohydration.

The purpose of this study was to test the effect of acute thermal hypohydration on the muscle endurance performance of three groups of differentially trained subjects. Group I consisted of six anaerobically trained athletes, Group II consisted of five aerobically trained athletes, and Group III consisted of six sedentary individuals. Experimental trials involved maximal leg extensions performed on a Cybex II dynamometer under conditions of euhydration and hypohydration of minus 3% body weight.
