Comparative Study of 1444 nm Laser Monotherapy versus Integrated Liposuction in the Treatment of Axillary Osmidrosis.

Background and Objectives: The 1444 nm wavelength Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser treatment is an efficient method for treating axillary osmidrosis (AO); however, it has a relatively low treatment persistence. To address this issue, we performed integrated liposuction surgery with a laser to treat AO and compared the results with those of a group treated only with a laser. Materials and Methods: This study compared the outcomes of AO treatment between the two groups up to six months postoperatively. The first group of 18 patients underwent laser treatment alone, and the second group of 12 patients underwent integrated liposuction surgery in addition to laser treatment. Outcomes were assessed using the following variables: degree of malodor (DOM), sweating area, patient satisfaction, pain levels, and complications, such as burns, swelling, and contractures. Results: Compared to the laser-only group, the integrated liposuction group demonstrated significantly superior outcomes in terms of DOM (p = 0.002) and patient satisfaction (p = 0.006), as well as a reduction in the sweating area (p = 0.012). The pain rating was higher in the liposuction group, but the difference was not statistically significant (p = 0.054). Compared with the patients in the integrated liposuction treatment group, those in the laser treatment group exhibited a significantly higher number of burns under the axillae (p = 0.025). However, no significant differences were observed in the swelling or contracture between the groups. Conclusions: Integrated liposuction with laser therapy significantly improved treatment outcomes, including malodor, patient satisfaction, sweat test results, and decreased complication rates.

Functional characterization of variants in human ABCC11, an axillary osmidrosis risk factor.

Human ATP-binding cassette transporter C11 (ABCC11) is a membrane protein exhibiting ATP-dependent transport activity for a variety of lipophilic anions including endogenous substances and xenobiotics such as anti-cancer agents. Accumulating evidence indicates that ABCC11 wild type is responsible for the high-secretion phenotypes in human apocrine glands including wet type of earwax and the risk of axillary osmidrosis. Also, a less-functional variant of ABCC11 was reportedly associated with a risk for drug-induced toxicity in humans. Thus, functional change in ABCC11 may affect individual's constitution and drug toxicity, which led us to reason that functional validation of genetic variations in ABCC11 should be of importance. Therefore, in addition to p.G180R (a well-characterized non-functional variant of ABCC11), we studied cellular expression and function of 10 variants of ABCC11. In this study, ABCC11 function was evaluated as an ATP-dependent transport of radio labeled-dehydroepiandrosterone sulfate using ABCC11-expressing plasma membrane vesicles. Except for p.G180R, other 10 variants were maturated as an N-linked glycoprotein and expressed on the plasma membrane. We found that six variants impaired the net cellular function of ABCC11. Among them, p.R630W was most influential. Including this identification of a significantly-dysfunctional variant, our findings will extend our understanding of genetic variations and biochemical features of ABCC11 protein.

Eccrine Angiomatous Hamartoma with Atypical Localization Treated by Mohs Micrographic Surgery.

ABSTRACT: Eccrine angiomatous hamartoma (EAH) is a rare hamartoma characterized by a benign proliferation of eccrine glands and vascular structures in the dermis. These tumors rarely regress spontaneously, so surgical excision of the involved tissue is required when pain or enlargement occurs. Here, the authors report the clinical case of a patient affected by an extremely painful EAH with the atypical localization at the last phalanx of the thumb of the right hand with involvement of nail matrix and nail bed. This report aims to emphasize the application of Mohs micrographic surgery for the treatment of painful EAH in a very difficult area at potential risk of amputation while preserving the maximum anatomical integrity and function of the damaged area. These results can pave the way for the use of Mohs micrographic surgery for very carefully selected benign neoplasms when their surgical removal is required.

Effect of optimizing the use of endoscope on the efficiency of microdynamic bromhidrosis removal operation.

BACKGROUND: Bromhidrosis, also known as body odor, is a common disease in life, which often occurs in young adults. The histological basis of bromhidrosis is the hyperplasia of apocrine sweat glands. OBJECTIVE: To compare the effects of different methods of endoscopy in microdynamic axillary osmidrosis removal on curative effect, complications, and surgical efficiency. METHODS: A total of 149 patients with axillary osmidrosis were treated in our hospital from January 2020 to December 2021. They were treated with endoscopic assistance in the whole process of operation (Group A) and endoscope-assisted exploration after blind rotary cutter suction (Group B), respectively, and the curative effect, complication rate, and surgical efficiency were evaluated. RESULTS: There was no significant difference in the curative effect and complication rate between the two groups, but the endoscope-assisted exploration group after suction with rotary cutter (Group B) had higher surgical efficiency. CONCLUSION: On the basis of professional use of rotary cutter, it is efficient to choose endoscope to check the excision of sweat gland in the operation area and stop bleeding in time after blind suction.

Bromhidrosis treatment modalities: A literature review.

BACKGROUND: Treatment options for Bromhidrosis include botulinum toxin therapy, microwave-based therapy, laser therapy, and surgical intervention. Limited studies compare their efficacies. OBJECTIVE: The purpose of this literature review is to compare the efficacy and safety of these treatments for bromhidrosis. METHODS: A PubMed search included terms bromhidrosis and bromhidrosis AND treatment. RESULTS: A total of 25 articles were reviewed. Botulinum toxin therapy shows consistent benefit but requires repeated therapies. Microwave therapies have shown promising results but require larger cohort sizes with bromhidrosis. Similarly, laser therapy has shown promise with biopsy-proven results, but long-lasting effects remain unknown. Surgery has the best long-term prognosis, but the ideal surgical method remains unknown. LIMITATIONS: Each study varied in their treatment interval and method of assessing bromhidrosis, making direct comparisons difficult. CONCLUSIONS: Managing bromhidrosis requires shared decision making with the patient. Mild-to-moderate symptoms may be treated initially with botulinum toxin therapy. In cases that are refractory, laser therapy should be considered, as it is better studied than microwave therapy currently. Lastly, if the condition is severe and refractory to other options, surgery can be considered, although the ideal method remains unknown.

A possible role for second-hit postzygotic GJB2 mutation in porokeratotic eccrine ostial and dermal duct nevus.

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare type of epidermal nevus involving the eccrine acrosyringia. It typically presents as asymptomatic linear keratotic papules and plaques along the lines of Blaschko and predominantly affects the extremities. This disease has recently been linked to somatic mutations within the GJB2 locus. Only four GJB2 mutations have been previously documented for PEODDN, and the underlying genetic basis remains inconclusive. Herein, we report an 18-year-old female with a hyperkeratotic plaque on the dorsa of the proximal interphalangeal joint of her right ring finger, as well as multiple small hyperkeratotic papules linearly distributed on the lateral sides of her fingers occurring since birth. Histopathological results revealed prominent parakeratotic cornoid lamella-like tiers at the opening of the eccrine secretory ducts. Whole-exome sequencing of the affected skin tissue revealed a heterozygous germline mutation and a postzygotic somatic mutation in GJB2. In summary, this study presents a case of PEODDN with compound heterozygous mutations in GJB2, which broadens the genetic spectrum of this disease entity and implies a possible role for second-hit mutations in the pathogenesis of PEODDN.

Complex sweat gland hamartoma: A case report.

Syringocystadenoma papilliferum (SCAP), tubular apocrine adenoma (TAA), and eccrine nevus are rare benign sweat gland tumors with varied clinical presentations but generally distinctive histomorphologic profiles. TAA and SCAP have been associated with other cutaneous hamartomas, most commonly with nevus sebaceus. Additionally, TAA and SCAP have uncommonly co-occurred in the same lesion. In contrast to nevus sebaceus, eccrine nevus is considerably less common and is rarely associated with other benign adnexal lesions. Here we present an unusual case of a complex sweat gland hamartoma containing features of syringocystadenoma papilliferum, tubular apocrine adenoma, and eccrine nevus in a 7-year-old female.

Comparative Study of En Bloc Excision and Dermal Shaving in Treating Axillary Osmidrosis.

BACKGROUND: Axillary osmidrosis is a distressing problem caused by hyperactivity of apocrine glands. There have been numerous studies on various surgical treatment methods. In this study, we evaluated the effectiveness of en bloc excision in comparison with dermal shaving. METHODS: The electronic records of 146 patients (286 axillae) who underwent surgery at our center for axillary osmidrosis between January 2009 and December 2020 were reviewed. Twenty-five patients (49 axillae) underwent en bloc excision and 121 (237 axillae) underwent dermal shaving. Patients in the en bloc excision group underwent Minor test preoperatively to detect sweating areas. Severity of osmidrosis was graded using a 4-point scale (0-3). A satisfaction questionnaire was used to evaluate patient experiences in the 2 types. RESULTS: Mean operation time was significantly shorter in the en bloc excision group than in dermal shaving group. Most en bloc excisions were performed on an outpatient basis under local anesthesia. Both groups showed an improvement in osmidrosis score at 6 months after surgery. A satisfaction questionnaire revealed better perioperative experiences in the en bloc excision group. Various surgical complications such as hematoma, wound dehiscence, and flap necrosis occurred in the dermal shaving group, and the en bloc excision group experienced significantly fewer complications that required intervention. CONCLUSIONS: En bloc excision combined with Minor test effectively reduces malodor without causing severe complications. In addition, perioperative patient satisfaction was better in the en bloc excision group than in the dermal shaving group as en bloc excision provided more rapid returns to normality and simplified communications with patients.

Potential use of microwave technology in dermatology.

BACKGROUND: Microwaves are used in medicine for diagnostics, and treatment of cancer. Recently, novel microwave devices (Swift®, Emblation Ltd, UK and miraDry®, Miramar Labs Inc., CA) have been cleared by the FDA and Health Canada for various dermatological conditions. OBJECTIVE AND METHODS: To review the dermatological use of microwave-based treatments (plantar warts, corns, actinic keratosis, dermatophytosis, axillary hyperhidrosis, osmidrosis, and hidradenitis suppurativa). Clinical trials, case reports, or in vitro studies for each condition are summarized. RESULTS AND CONCLUSION: Microwaves are a promising alternative therapy for cutaneous warts, actinic keratosis, axillary hyperhidrosis, and osmidrosis, with favorable safety profiles. However, patients with hidradenitis suppurativa have had negative clinical outcomes. Limited treatment of corns showed good pain reduction but did not resolve hyperkeratosis. A preliminary in vitro study indicated that microwave treatment inhibits the growth of T. rubrum. We present the first case of toenail onychomycosis successfully treated with microwaves. Despite the advancements in the use of microwaves, the mechanism of action in non-ablative treatment is not well understood; further research is needed. More high-quality randomized clinical trials with larger groups and long follow-up periods are also required to evaluate the clinical benefits and possible adverse effects of microwaves in treating dermatological conditions.
