ABSTRACT

Secondary focal hyperhidrosis is usually due to peripheral or central neuronal defects and is a complex dysfunction of the parasympathetic and sympathetic nervous system. Palmoplantar hyperhidrosis has been described with various types of polyneuropathies such as diabetic but has not previously been described with isoniazid. We report a 15-year-old boy, being followed for neurotuberculosis, who presented with burning sensation and hyperhidrosis of both palms and soles five months after starting antitubercular therapy. With oral pyridoxine supplementation, the paraesthesia and hyperhidrosis reduced to minimal severity over the next four months. Before commencing antiperspirants, simple pyridoxine supplementation can lead to the reversal of symptoms in such cases.

Hyperhidrosis Disease Severity Measure-Axillary (HDSM-Ax): Evaluation of Measurement Performance

J Drugs Dermatol. 2021 Apr 1;20(4):410-418. doi: 10.36849/JDD.2021.5569.

ABSTRACT

BACKGROUND: Clinical trials of primary axillary hyperhidrosis (AHH) require rigorous measurement of AHH severity from the patient’s perspective. Previously, we reported conceptualization and item content development for the Hyperhidrosis Disease Severity Measure-Axillary (HDSM-Ax) scale.

OBJECTIVE: To evaluate the psychometric performance and estimate clinically meaningful change scores for the HDSM-Ax in a Phase IIb clinical study of sofpironium bromide gel for AHH.

METHOD: HDSM-Ax measurement performance was analyzed in trial response data using two psychometric paradigms: Classical Test and Rasch Measurement Theories (CTT; RMT). HDSM-Ax meaningful change scores were estimated from anchor-based methods using two global summary questions of hyperhidrosis severity and the Hyperhidrosis Disease Severity Score (HDSS).

RESULTS: HDSM-Ax satisfied CTT and RMT criteria as a fit-for-purpose outcome measure in AHH clinical trials. Within-person anchor-based analyses indicated a 1-point change in HDSM-Ax severity score (range, 0–4) represents a clinically meaningful change in AHH severity.

CONCLUSION: HDSM-Ax is a well-defined and reliable measure of AHH severity. A 1-point change in HDSM-Ax score is clinically meaningful. J Drugs Dermatol.20(4):410-418. doi:10.36849/JDD.5569.

Effect of botulinum toxin in stellate ganglion for craniofacial hyperhidrosis: a case report

J Int Med Res. 2021 Mar;49(3):3000605211004213. doi: 10.1177/03000605211004213.

ABSTRACT

Craniofacial hyperhidrosis causes sweating of the face and scalp due to excessive action of the sweat glands and manifests when patients become tense/nervous or develop an elevated body temperature. If noninvasive treatments are ineffective, invasive treatments such as a sympathetic block and resection are considered. A 32-year-old woman with no specific medical history was referred for uncontrolled craniofacial hyperhidrosis that included excessive sweating and hot flushing. Physical examination showed profuse sweating, and infrared thermography showed higher temperature in the neck and face than in the trunk. The patient underwent several stellate ganglion blocks, and her symptoms improved; however, the treatment effect was temporary. Botulinum toxin was then injected into the stellate ganglion. At the time of this writing, her sweating had been reduced for about 6 months and she was continuing to undergo follow-up. Craniofacial hyperhidrosis is a clinical condition in which patients experience excessive sweating of their faces and heads. It is less common than palmar and plantar hyperhidrosis. Botulinum toxin injection into the stellate ganglion is simple and safe and produces longer-lasting effects than other treatments, such as endoscopic sympathectomy and a single nerve block.

How to diagnose and measure primary hyperhidrosis: a systematic review of the literature

Clin Auton Res. 2021 Mar 27. doi: 10.1007/s10286-021-00794-6. Online ahead of print.

ABSTRACT

PURPOSE: Hyperhidrosis (i.e. excessive sweating) is diagnosed from patient medical history and physical examination. In addition, focal sweat measurements can substantiate the hyperhidrosis diagnosis. Likewise, the impact of living with hyperhidrosis can be assessed with patient-reported outcome measures. However, no consensus exists on how to diagnose hyperhidrosis, how to quantify the disease, or how to measure the impact hyperhidrosis has on patients. Therefore, the objective of this review was to summarize the literature on diagnostic criteria, focal sweat measurement methods, and patient-reported outcome measures of hyperhidrosis.

METHODS: A literature search of Cochrane Library, Embase, and PubMed was conducted. Studies that included and aimed at developing or validating hyperhidrosis diagnostic criteria, focal sweat measurement methods, or patient-reported outcome measures for individuals with hyperhidrosis were eligible for inclusion. The methodological quality of diagnostic accuracy studies about focal sweat measurement methods was determined using the Quality Assessment of Diagnostic Accuracy Studies-2.

RESULTS: Overall, 33 studies were included. We identified two sets of hyperhidrosis diagnostic criteria, one scale for assessment of severity of hyperhidrosis sweating, four focal sweat measurement methods, and 15 patient-reported outcome measures.

CONCLUSION: The algorithm for diagnosing hyperhidrosis and focal sweat measurement methods needs validation in large cohorts. Most patient-reported outcome measures for hyperhidrosis are not adequately validated. A potential solution is to develop a core outcome set that can standardize outcomes reported in clinical trials.

Bilateral one-stage single-port sympathicotomy in primary focal hyperhidrosis, a prospective cohort study: treat earlier?

J Cardiothorac Surg. 2021 Mar 25;16(1):50. doi: 10.1186/s13019-021-01430-0.

ABSTRACT

BACKGROUND: Primary Focal Hyperhidrosis (PFH) has a detrimental effect on Quality of Life. Repetitive, non-curative symptomatic strategies dominate current treatment of PFH, in spite of the availability of an effective and permanent curative treatment like Endoscopic Thoracic Sympathectomy (ETS). Current surgical optimization may allow for a re-established position of sympathetic modulation in this treatment algorithm. We sought to evaluate the safety, effectiveness, and long-term results of a Bilateral One-stage Single-port Sympathicotomy (BOSS) procedure in PFH patients and to identify subgroups benefitting most.

METHODS: Prospective analysis of 163 patients, 35 (21.5%) underwent Rib-3 (R3) BOSS for palmar PFH, 58 (35.6%) R3-R5 BOSS for axillary PFH and 70 (42.9%) R3-R5 BOSS for combined palmar/axillary PFH. Effectiveness was measured using Skindex-29 and the Hyperhidrosis Disease Severity Scale (HDSS).

RESULTS: Overall Skindex-29-rating (46.5 ± 14.8 preoperatively vs 20.1 ± 20.6 postoperatively, p < 0.001), and HDSS score (3.71 ± 0.45 preoperatively vs 1.82 ± 0.86 postoperatively, p < 0.001) indicated a significant improvement in health-related quality of life after BOSS. R3 BOSS was superior to R3-R5 BOSS in terms of HDSS score (1.49 vs 1.91 respectively, p = 0.004) and in terms of severe compensatory hyperhidrosis, a frequently reported side-effect (17.1% vs 32.8% respectively, p < 0.001). No major complications occurred.

CONCLUSIONS: BOSS is safe, effective, and offers a long-term curative solution in the treatment of PFH. Especially in the palmar PFH subgroup, R3 BOSS treatment results compare favorably to the treatment results of non-curative alternatives published in the current literature. Therefore, R3 BOSS should be offered to all patients with severe PFH, reporting insufficient benefit of treatment options such as oral and/or local agents.

Evaluation of The Serum Magnesium and Vitamin D Levels and The Risk of Anxiety in Primary Hyperhidrosis

J Cosmet Dermatol. 2021 Mar 18. doi: 10.1111/jocd.14075. Online ahead of print.

ABSTRACT

BACKGROUND: Excessive sweating is considered primary hyperhidrosis if it is triggered by emotional states without any thermogenic or other underlying disease from the eccrine glands. This may be due to dysfunction in the autonomic nervous system.

AIM: To investigate the relationship between Vitamin D and Mg deficiency and the risk of anxiety and depression in patients with primary hyperhidrosis.

METHODS: This cross-sectional, case-control study was conducted between July and October 2019. 49 primary hyperhidrosis patients in Group I and 47 age and gender matched healthy individuals in Group II were included in the study.

RESULTS: The mean 25 (OH) D and Mg levels in Group I were statistically significantly lower than in Group II (p <0.001 and p = 0.002, respectively). Statistically significant differences were found between the groups in terms of anxiety and depression (p <0.001 and p = 0.033, respectively). There was no significant relationship between the HADS-A / HADS-D scores and the severity of primary hyperhidrosis (r = -0.131, p = 0.096; correlation coefficient = 0.232, p = 0.447). However, a significant correlation was observed between HADS-A scores and serum Mg levels (r = -0.439, p = 0.007).

CONCLUSION: Anxiety and depression are common in patients with primary hyperhidrosis. As shown in this study, both anxiety and depression can be seen with low Mg levels in patients with primary hyperhidrosis. This could possibly be related to the pathological mechanism involving Vitamin D and Mg, which determines the common pathway affecting primary hyperhidrosis and anxiety / depression.

Epidemiology of Hyperhidrosis in Danish Blood Donors

Acta Derm Venereol. 2021 Mar 18. doi: 10.2340/00015555-3790. Online ahead of print.

ABSTRACT

The risk factors and disease implications of hyper-hidrosis are unknown. The objectives of this retrospective cohort study were to estimate the prevalence of hyperhidrosis and to compare demographic, life-style, and socioeconomic parameters in blood donors with and without self-reported or hospital-diagnosed hyperhidrosis. The study included blood donors from the Danish Blood Donor Study for the period 2010-2019. Registry data were collected from Statistics Denmark. Overall, 2,794 of 30,808 blood donors (9.21%; 95% confidence interval (95% CI) 8.75-9.40) had self- reported hyperhidrosis and 284 of 122,225 (0.23%; 95% CI 0.21-0.26) had hospital-diagnosed hyperhidrosis. Self-reported hyperhidrosis was associated with smoking (odds ratio (OR) 1.17; 95% CI 1.05-1.31), overweight (OR 1.72; 95% CI 1.58-1.87), “unemployed” (OR 1.60; 95% CI 1.24-2.08), “short education” (OR 0.76; 95% CI 0.64-0.90), and lower income (beta-coefficient -26,121; 95% CI -37,931, -14,311). Hospital-diagnosed hyperhidrosis did not differ from controls. Thus, self-reported hyperhidrosis was associated with potential hyperhidrosis risk factors (smoking, overweight) and disease implications (unemployment, low education level and income).

Effects of lower thoracic sympathicotomy on plantar hyperhidrosis

J Thorac Dis. 2021 Feb;13(2):664-670. doi: 10.21037/jtd-20-2437.

ABSTRACT

BACKGROUND: The purpose of this study was to investigate whether performing lower thoracic sympathicotomy (LTS) from T10 to T12 affects plantar hyperhidrosis in patients with palmo-plantar (PP) or palmo-axillary-plantar (PAP) hyperhidrosis.

METHODS: Between January 2015 and January 2020, all consecutive patients with primary hyperhidrosis who underwent bilateral thoracoscopic sympathicotomy and met the inclusion criteria were included. Sympathicotomy was performed using one of the following two methods: the conventional upper thoracic vs. expanded thoracic sympathicotomy. In the expanded thoracic sympathicotomy, we expanded the level of sympathicotomy ranging from R5 to R12 in addition to the conventional upper thoracic sympathicotomy (R3 or R4). In cases of the expanded thoracic sympathicotomy, we defined the LTS as a sympathicotomy of the levels ranging from R10 to R12, which are related to plantar hyperhidrosis.

RESULTS: A total of 103 subjects with PP (71 cases) or PAP (32 cases) hyperhidrosis were included. Palmar or axillary hyperhidrosis in all patients were alleviated after sympathicotomy. There was no difference in sweating decrease or CH according to the hyperhidrosis types or sympathicotomy techniques. In addition, no-LTS was performed in 77 cases and LTS was performed in 26 cases. In the no-LTS group, there were 65 and 12 cases of low and high degrees of CH, respectively. In the LTS group, there were 22 and four cases of low and high degrees of CH, respectively. There was no significant difference in CH between the no-LTS and LTS groups (P=0.981). Improvement in plantar hyperhidrosis in the no-LTS group was observed in 29 of 77 cases, while improvement in plantar hyperhidrosis in the LTS group was observed in 16 of 26 cases. The addition of LTS lead to significant improvement in plantar hyperhidrosis (P=0.034).

CONCLUSIONS: Performing LTS is a safe and feasible procedure that improved plantar sweating more so than it did in cases that did not undergo LTS. Therefore, we cautiously suggest that adding LTS helps in the treatment of plantar hyperhidrosis combined with palmar hyperhidrosis. Further studies on LTS are needed to validate these findings and will be helpful in establishing management guidelines.
