Hyperhidrosis
Conditions
Brief summary
Hyperhidrosis is a condition in which sweating is in excess of that required for normal regulation of body temperature. Commonly affected areas in primary hyperhidrosis include axillae, palms and soles. Secondary hyperhidrosis can affect scalp, face, neck, back, groin and legs. Hyperhidrosis can negatively impact, employment, relationships, or other aspects of quality of life. The investigators propose to investigate the use of a unique image-guided laser to specifically ablate eccrine sweat glands.
Interventions
Iontophoresis of methylene blue is used to identify the sweat glands. An image guided fractional erbium laser is used to specifically target these glands for ablation.

Study design
Intervention model description
The study involves a single group of patients with Hyperhidrosis. Left and right palms are randomized for treatment versus control (untreated).
Eligibility
Inclusion criteria

Subject in appropriate physical health to ride a stationary bicycle to the point of eliciting sweat. 11. No known allergy to iodine or potato starch
Exclusion criteria
1. Pregnancy 2. Subjects on systemic treatment for hyperhidrosis, such as anticholinergic drugs (e.g. glycopyrrolate), sedatives or tranquilizers, within the past 8 weeks. 3. Subjects who have undergone surgical excision of sweat glands or sympathectomy for hyperhidrosis. 4. Subjects with an underlying disorder, such as neurologic injury or disease affecting the autonomic system, vascular disorders and metabolic disorders (e.g. hyperthyroidism, diabetes mellitus) that can produce hyperhidrosis 5. Subjects with a history of coronary artery disease. 6. Subjects with a history of poor compliance or psychosis 7. Subjects taking SSRIs, SNRIs, TCAs, or MAOIs 8.

Known allergy to iodine or potato starch.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Gravimetric Measurements of Changes in Sweat Production | Assessed at baseline, week 1, week 2, week 4, month 3, and month 6 | Subjects will be asked to exercise using a stationary bike until sweating is observable. After drying the surface, a pre-weighted filter paper under occlusive dressing (Tegaderm) is applied to the test site for a period of five minutes, measured by a stopwatch. After five minutes, the Tegaderm and absorptive pad are removed. The absorptive pad and Tegaderm are weighed before and after sweating, and rate of sweat production is calculated. |
