Filter by:This is a Prospective, Double Blinded, Placebo Controlled, Randomized, Cross-over trial using Qbrexza Cloths to treat hyperhidrosis of amputation sites. There is a 2 week screening period where patients will use an activity monitor to establish baseline activity level, then patients will be randomized to receive either Qbrexza cloths or placebo for 4 weeks, then a 2 week washout, and then a 4-week cross-over treatment period.
SUMMARY Objective To assess the efficacy of Nd:YAG laser treatment on eccrine sweat production in the axillae of persons experiencing excessive axillary hyperhidrosis. Design Randomised, within-person controlled clinical trial. Setting One Dermatology Department, at a University hospital in Denmark, from 2018-20. Participants A total of 10 participants enrolled after signing informed consent from the patients attending the hyperhidrosis clinic. Interventions Participants will receive one Nd:YAG laser-treatment of either left or right axilla. The treated area will be cooled with ice during and after laser treatment. Prior to treatment, patients can use lidocaine-prilocaine 5% cream at the treatment site on an optional basis. Main outcome measures Primary outcome measure will be reduced excessive sweat production (%points) monitored by an iodine-starch test assessed at 1-month follow-up compared to baseline. A 30% reduction in sweat production in the Nd:YAG laser-treatment relative to control, will be considered clinically significant. Key secondary outcome measures include (1) weighing the sweat by gravimetric testing, (2) patient assessment of sweat production on a Hyperhidrosis Disease Severity Scale (HDSS) - also assessed at 1 month from baseline. Safety around the use of Nd:YAG laser-treatment will be monitored by registering pain during treatment on a visual analogue scale, as well as monitoring of adverse events immediately as well as one week after treatment. As for the purpose of further exploratory analyses (both benefits and harms), all outcome measures will be re-collected 24 months after treatment. Timelines and dissemination For the collection of the primary data (i.e. primary endpoint being assessed after 1 month), First Patient First Visit (FPFV) will take place in November 2018 and Last Patient Last Visit (LPLV) will be in March 2019. The investigators plan to present data internationally at e.g. the European Academy of Dermatology and Venerology as well as nationally to the Danish Dermatology Society and to the Hyperhidrosis Patient Association. Results will be published in an internationally recognised peer reviewed (biomedical) journal. Trial registration: Danish Research Ethics Committee (approved, protocol number: SJ-689); ClinicalTrials.gov: NCT pending (2018-11-22).
Primary hyperhidrosis is a disorder characterized by excessive and chronic sweating in the absence of a sweating trigger. The disorder can be severe and interfere with normal daily activities of the patients. The gold-standard treatment in severe cases of hyperhidrosis is thoracoscopic sympathectomy betweenT2 and T4. These procedures are regularly performed in surgical units under general anaesthesia which needs special anesthetic considerations which is complex and associated with a lot of complications. Radiofrequency ablation of the sympathetic chain for treatment of hyperhidrosis is considered alternative to thoracoscopic sympathectomy. The procedure is safe, inexpensive and done under sedation with local anaesthesia in an outpatient setting, but its success rate is still significantly lower than endoscopic sympathectomy. The purpose of this study is to determine whether adding phenol 6% in a mixture with glycerin will increase the efficacy of fluoroscopy guided radiofrequency ablation of T2, T3 sympathetic ganglia in hyperhidrosis in comparison to surgery without significant side effects to provide safe and effective method rather than surgery.
Primary axillary hyperhidrosis is a common idiopathic disorder of the eccrine sweat glands that interferes with daily activities and causes significant social distress. This pilot study is designed to evaluate the efficacy and histologic effects of the 1210nm diode laser for the treatment of axillary hyperhidrosis. Initial results may inform the design of an anticipated larger prospective controlled trial. Study participants will receive one laser treatment to one randomly-assigned axilla using the 1210 nm diode laser, and two treatments to the opposite axilla. Changes in sweating will be measured both by quantitative gravimetric analysis of sweat production and by expert panel evaluation of photographs of the starch-iodine test performed on each axilla. Participants will also be asked to subjectively classify the severity of their axillary sweating. These measures will be performed at pretreatment and at one, three, and six months following treatment. Biopsies of both axillae will be done before and two weeks after treatment to assess histologic changes to the eccrine gland and surrounding structures. Treatment of axillary hyperhidrosis with the 1210nm diode laser is a novel approach based on the unique absorption characteristics of this wavelength. We hypothesize that selective heating of lipids at the appropriate tissue level will impact adjacent eccrine glands typically seated at the dermo-hypodermal junction, leading to subjective and/or objective decreases in eccrine secretions. This type of treatment may offer an effective, non-invasive and safe alternative to current treatment modalities.
