Chronic idiopathic constipation may be the result of an autonomic neuropathy. This hypothesis was tested in 23 constipated patients and 17 age matched controls, using the acetylcholine sweat spot test devised to test autonomic integrity in diabetes. Acetylcholine (0.01%) was injected in the dorsum of the foot painted with a mixture of starch and iodine. Active sweat glands appeared on the surfa...

BACKGROUND In Wilson disease, copper is not sufficiently excreted into bile due to the absence or malfunction of the Wilson protein copper ATPase in the excretory pathway of hepatocytes. Copper is found in sweat. It is unknown if the Wilson protein plays a role in copper excretion into sweat. It is the aim of this study to investigate Wilson protein expression in sweat glands and analysing its ...

BACKGROUND Sweating can worsen atopic dermatitis (AD). The purpose of this work was to study the associations between reactivity to autologous sweat and the clinical severity of AD as well as investigate the possible wheal-inducing factors of sweat. METHODS Intracutaneous skin tests with autologous sweat were performed on 50 AD patients and 24 control subjects. In skin biopsies, tryptase and ...

A well produced evidence based guideline has been developed in response to a national audit that demonstrated wide variations in the performance of sweat tests. Accurate and reliable sweat test results will be particularly important with the advent of neonatal screening. The guideline recommendations include the collection and analysis of sweat samples, and interpretation of results. It emphasi...

ISSN 0001-5555 There are many methods for assessing abnormalities in perspiration, including practical, qualitative, and quantitative methods. Among the methods of visualizing local and generalized perspiration, the Minor, or starch-iodine, test is widely used to identify areas of excessive or ...

The diagnosis of cystic fibrosis (CF) can be difficult if the sweat test and routine deoxyribonucleic acid (DNA) analysis are inconclusive. Under these circumstances, measurement of nasal potential difference (NPD) was proposed as a complementary diagnostic tool, as demonstrated in subjects bearing the G551S or 3849+10KbC-->T mutations. The purpose of the present study was to verify the diagnos...

OBJECTIVES To examine the results of thermoregulatory sweat testing in patients with erythromelalgia and to compare them with the results of other neurophysiologic tests of small-fiber nerve function. DESIGN Retrospective study. SETTING Tertiary referral center. PATIENTS Thirty-two consecutive patients with erythromelalgia who had thermoregulatory sweat testing in addition to vascular and...
