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...

Athletes lose water and electrolytes as a consequence of thermoregulatory sweating during exercise and it is well known that the rate and composition of sweat loss can vary considerably within and among individuals. Many scientists and practitioners conduct sweat tests to determine sweat water and electrolyte losses of athletes during practice and competition. The information gleaned from sweat...

We investigated whether the eccrine sweat glands must actively produce sweat during heat acclimation if they are to adapt and increase their capacity to sweat. Eight volunteers received intradermal injections of BOTOX, to prevent neural stimulation and sweat production of the sweat glands during heat acclimation, and saline injections as a control in the contralateral forearm. Subjects performe...

BACKGROUND Sweat testing procedures are perceived to vary widely. AIM To evaluate variability in sweat collection, analysis, and interpretation. METHODS Questionnaire responses from 30 self selected centres: 15 paediatric centres, and 15 district general hospitals. RESULTS Centres carried out 30-400 tests per year (median 100), with a diagnostic rate of 1:5-152 (median 1:30). Staff perfor...

BACKGROUND Laptop computers may release nickel and cobalt when they come into contact with skin. Few computer brands have been studied. OBJECTIVES To evaluate nickel and cobalt release from laptop computers belonging to several brands by using spot tests, and to quantify the release from one new computer by using artificial sweat solution. METHODS Nickel and cobalt spot tests were used on t...

OBJECTIVE Chronic rhinosinusitis results in significant morbidity in the pediatric population; however, no predisposing factor is found in many cases. Cystic fibrosis (CF) is a recognized cause of chronic rhinosinusitis. Although the carrier frequency for CF ranges from 3% to 4% in the general white population, the prevalence of mutations in the CF transmembrane conductance regulator (CFTR) amo...

Infants with positive CF newborn screening (NBS) results are called to a CF Centre for verification. Those, in whom the sweat test is elevated, undergo further medical procedures. The aim of our study was to evaluate the applicability of Nanoduct - a new system measuring sweat conductivity and giving immediate results in a CF NBS protocol. Measurements with Nanoduct were compared with the class...

The sweat test was performed by the method of Gibson and Cooke on 36 children with second and third degree malnutrition, aged from 2 months to 4 years. The results were compared with those from 32 healthy, well nourished controls in the same age range. Determinations were made of sodium and chloride concentrations, chloride/sodium ratio, and the sum of the concentrations of the two electrolytes...
