Sweat test with Gibson Cooke (GC) method is the diagnostic gold standard for cystic fibrosis (CF). Recently, alternative methods have been introduced to simplify both the collection and analysis of sweat samples. Our aim was to compare sweat chloride values obtained by GC method with other sweat test methods in patients diagnosed with CF and whose CF diagnosis had been ruled out. We wanted to d...

Although acrometastases are rare but clinically they are considered important. Their etiology is quite different from the metastases to other sites; bronchogenic carcinoma is by far the most frequent case. The prognosis is always similar to metastatic bronchial cancer with an average survival of three mo...

The popularity of tattoos has increased tremendously in the last 10 yr particularly among athletes and military personnel. The tattooing process involves permanently depositing ink under the skin at a similar depth as eccrine sweat glands (3-5 mm). PURPOSE The purpose of this study was to compare the sweat rate and sweat Na concentration of tattooed versus nontattooed skin. METHODS The part...

The purpose of this study was to investigate the validity of infrared tympanic temperature (IR T(ty)) as a thermal index to evaluate the heat strain of workers in hot environments, in comparison with rectal temperatures at various depths (T(re-4, -8, and -16) for 4, 8 and 16 cm from the anal sphincter). Eight males underwent twelve experimental conditions: two activities (rest and exercise) × t...

Sweat chloride concentrations above 40 mmol/l are unusual in newborns screened for cystic fibrosis and should be followed up. Centiles of sweat chloride concentrations in newborns positive to cystic fibrosis neonatal screening are presented. There are no significant correlations between age at sweat testing and sweat chloride concentration or quantity of sweat collected.

This study compared simultaneous whole body washdown (WBW) and regional skin surface (REG) sweat collections to generate regression equations to predict WBW sweat Na(+) concentration ([Na(+)]) and K(+) concentration ([K(+)]) from single- and five-site REG sweat patch collections. Athletes (10 men, 10 women) cycled in a plastic chamber for 90 min in the heat. Before exercise, the subject and bik...

BACKGROUND Eccrine sweat secretion is of central importance for control of body temperature. Although the incidence of sweat gland dysfunction might appear of minor importance, it can be a real concern for people with either hypohidrosis or hyperhidrosis. However, sweat gland function remains relatively poorly explored. OBJECTIVES To investigate the function of single human sweat glands. ME...

Sweat gland adenocarcinoma is a relatively uncommon malignancy. Clinical features are painless red or violet papules and nodules that can occasionally become ulcerated. The biological behavior is aggressive and metastatic sweat gland carcinoma spreads through the lymphatic. The treatment of choice is wide surgical excision with regional lymph node dissection. The portrayed ase was a 60-year-old...
