BACKGROUND There are few published data on the clinical characteristics of hyperhidrosis. OBJECTIVE To describe the functional impairment caused by primary focal hyperhidrosis. METHODS Patients with hyperhidrosis (n = 345) were enrolled at the Department of Dermatology, University of Würzburg. Controls (n = 154) were a convenience sample of subjects without hyperhidrosis. Hyperhidrosis char...

OBJECTIVE To assess quality of life before and after thoracoscopic sympathectomy for treatment of primary hyperhidrosis. METHODS we conducted an observational, analytical, cross-sectional and quantitative study. We evaluated patients undergoing thoracoscopic sympathectomy for primary axillary hyperhidrosis, primary palmar hyperhidrosis, and axillary hyperhidrosis associated with palmar one. W...

dermatitis or bacterial and mycological infections (1). BTXA has been used recently to treat focal hyperhidrosis (gustatory sweating, palmo-plantar and axillary hyperhidrosis) (4, 5). There are no data available for the treatment of stump hyperhidrosis. We used BTXA for stump hyperhidrosis in a dosage comparable to that used in palmar hyperhidrosis, i.e. 100 U of Botox. The treatment was very e...

OBJECTIVE To compare two surgical techniques (denervation levels) for sympathectomy using video-assisted thoracoscopy to treat palmar hyperhidrosis in the long-term. METHODS From May 2003 to June 2006, 60 patients with palmar hyperhidrosis were prospectively randomized for video-assisted thoracoscopic sympathectomy at the T2 or T3 ganglion level. They were followed for a mean of 20 months and...

Many drugs including anti-depressants and anti-psychotics are known to cause excessive sweating (hyperhidrosis). Hyperhidrosis may be caused by drugs acting at the hypothalamus, spinal thermoregulatory centres, and sympathetic ganglia or at the eccrine-neuroeffector junction. Hyperhidrosis can be distressing and embarrassing symptom, which if not addressed properly, may lead to non-concordance ...

BACKGROUND Hyperhidrosis affects approximately 3% of the population. The nature of those patients presenting for treatment has not been well studied, however. OBJECTIVE The objective was to perform a descriptive, multicenter study of patterns of patients referred for treatment of focal hyperhidrosis. METHODS AND MATERIALS A convenience sampling of consecutive patients referred for considera...

BACKGROUND The current epidemiologic data on hyperhidrosis are scarce and insufficient to provide precise prevalence or impact estimates. OBJECTIVE We sought to estimate the prevalence of hyperhidrosis in the US population and assess the impact of sweating on those affected by axillary hyperhidrosis. METHODS A nationally representative sample of 150,000 households was screened by mailed sur...

BACKGROUND There is a paucity of data on the prevalence of multifocal primary hyperhidrosis and changes in hyperhidrosis severity over time. OBJECTIVE The goal of this study was to better understand multifocal primary hyperhidrosis, prevalence and distribution of hyperhidrosis by focal site, age of onset of symptoms by focal area, and change in hyperhidrosis severity over time and with season...

Hyperhidrosis is a disorder of excessive sweating beyond what is physiologically necessary for thermoregulation. Primary hyperhidrosis is localized; it can affect the axillae, palms, soles, face, and other areas and is idiopathic. The prevalence of hyperhidrosis in the United States is estimated to be 2.8% of the population, with about one-half (1.4%) of these individuals having the axillary fo...

Sweating is an important mechanism for ensuring constant thermoregulation, but hyperhidrosis may be disturbing. We present five cases of hemifacial hyperhidrosis as a compensatory response to an/hypohidrosis caused by cervical disc herniation. All the patients complained of hemifacial hyperhidrosis, without anisocoria or blepharoptosis. Sweat function testing and thermography confirmed hyperhid...
