RESUMEN
PURPOSE: Hyperhidrosis can be a debilitating disease that leads to the deterioration of well-being. In this study, the objective was to compare the health-related quality of life (HRQOL) in individuals with and without hyperhidrosis by conducting a systematic review and meta-analysis. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Meta-analysis Of Observational Studies in Epidemiology checklist were employed. We systematically searched Cochrane Library, Embase and PubMed. Two authors independently assessed the literature and extracted the data. The risk of bias was assessed using the Newcastle-Ottawa Scale. A random-effects model was employed. The heterogeneity was determined using I2. RESULTS: Eleven studies met the eligibility criteria comprising 4297 and 147,604 participants with and without hyperhidrosis, respectively. The risk of bias ranged from high quality to very high risk of bias. The individuals with hyperhidrosis had a higher Dermatology Life Quality Index (mean difference 8.53; 95% confidence interval 3.47, 13.58; p = 0.0009) and a lower mental component summary of the short form-12 or -36 (mean difference -6.15; 95% confidence interval -9.00, -3.30; p < 0.0001) than the control individuals. No difference was found for the physical component summary score of the short form-12 or -36 (mean difference -0.88; 95% confidence interval -1.88, 0.12; p = 0.085). Studies using patient-reported outcomes, not included in the meta-analysis, showed similar results. CONCLUSION: Individuals with hyperhidrosis experience a reduced HRQOL that is clinically meaningful and leads to perceivable deteriorations in their well-being. The evidence shows a high degree of heterogeneity, which warrants additional studies.

PURPOSE: Hyperhidrosis has been associated with a reduced health-related quality of life (HRQoL). The role of common confounding factors of this association such as stress and socioeconomic status, however, remain largely unexplored, and may affect the management strategy for hyperhidrosis. Therefore, the study objective was to compare the HRQoL in individuals with and without hyperhidrosis while adjusting for confounders. METHODS: In this retrospective cohort study, data on the HRQoL measured by the short-form-12 questionnaire and self-reported hyperhidrosis were collected from the Danish Blood Donor Study-cohort. Data on international classification of disease-10 codes and redeemed prescriptions were collected from nationwide registries. Linear regression investigated the association between hyperhidrosis and HRQoL. RESULTS: Total 2794 (9.1%) of 30,808 blood donors had self-reported hyperhidrosis and 284 (0.2%) of 122,225 had hospital diagnosed hyperhidrosis. Self-reported hyperhidrosis was associated with a reduced mental HRQoL (adjusted beta coefficient - 1.10; 95% confidence interval - 1.37, - 0.82; p < 0.001) and physical HRQoL (adjusted beta coefficient - 0.90; 95% confidence interval - 1.09, - 0.70; p < 0.001). Hospital diagnosed hyperhidrosis was associated with a reduced mental HRQoL (adjusted beta coefficient - 0.91; 95% confidence interval - 1.82, - 0.04; p = 0.049). CONCLUSION: Hyperhidrosis is associated with a reduced HRQoL, independently of confounders or mode of diagnosis. This supports an approach primarily targeting hyperhidrosis.

The aim of this study was to compare the efficacies of systemic treatments with dupilumab, tralokinumab and Janus kinase inhibitors for moderate-to-severe atopic dermatitis. A systematic review following Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) guidelines was performed using Medline, EMBASE and Cochrane library. All randomized controlled trials investigating the efficacy of systemic treatments for moderate-to-severe atopic dermatitis in adults were included. Primary outcomes were the proportion of patients with atopic dermatitis achieving 50%, 75%, and 90% improvement in Eczema Area and Severity Index (EASI) score after dupilumab, tralokinumab or Janus kinase inhibitors. Nineteen studies totalling 6,444 patients were included. In monotherapy studies, upadacitinib 30 mg once daily had the numerically highest efficacy regarding EASI-50, EASI-75 and EASI-90. In combination therapy studies with topical corticosteroids, dupilumab 300 mg once every other week had highest efficacy regarding EASI-50, and abrocitinib 200 mg once daily had the highest score regarding EASI-75 and EASI-90. Analysis provided evidence that dupilumab, tralokinumab and Janus kinase inhibitors all had an acceptable efficacy profile and resulted in clinically relevant improvements in EASI score. Furthermore, upadacitinib and abrocitinib seem to have great potential to treat patients with atopic dermatitis. However, further studies are needed to determine the long-term efficacy of Janus kinase inhibitors in adults with moderate-to-severe atopic dermatitis.

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 (9.07%; 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).

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.

INTRODUCTION: The gold standard method for diagnosing primary hyperhidrosis (PHH) is based on seven patient-reported criteria. By determining an individual criterion's diagnostic accuracy, one can identify short-version classification models. METHODS: In this cross-sectional study, data were collected from Danish blood donors in 2021. Cohen's kappa and diagnostic accuracy were determined by comparing each criterion with the gold standard method. RESULTS: The study included 1,039 participants. Of them, 59 (5.7%) had PHH and 980 (94.3%) were classified as control individuals. The PHH major criterion "focal visible excessive sweating for at least 6 months without an apparent cause" had the highest prevalence in the participants with PHH compared to the control individuals (100% vs. 0.6%; p < 0.0001). The agreement between this criterion and PHH was Cohen's kappa = 0.95 (95% confidence interval [CI] 0.91-0.99), and its sensitivity was 1.00 (95% CI 0.94-1.00) and specificity 0.99 (95% CI 0.99-1.00). The other criteria showed lower agreement and diagnostic accuracy. CONCLUSIONS: The PHH major criterion showed near-perfect agreement and near-equal diagnostic accuracy compared with the gold standard method. This single criterion can be used as a short-form version to screen for PHH. Determination of reproducibility in independent populations is warranted.

Hyperhidrosis is a dermatosis presenting as pathologically excessive focal or generalized sweating. The stigmatizing nature of hyperhidrosis may cause patients to feel embarrassment and apprehension about their symptoms and experience a significant decrease in well-being. Severe cases of hyperhidrosis can also increase the risk of developing psychiatric and somatic comorbidities. Conventional non-surgical treatments of hyperhidrosis include aluminum salts, iontophoresis, botulinum toxin injections, and oral glycopyrronium. In recent years, new topical anticholinergic medications and devices have emerged that may improve the patients' symptoms and even prevent the development of comorbidities. The treatment of hyperhidrosis can be a complex matter and may require the combination of several therapies. The purpose of this paper was to firstly review the literature on existing non-surgical treatment options for hyperhidrosis, and secondly provide a stepwise approach to investigating and treating patients with hyperhidrosis.

BACKGROUND: A few studies have described an increased prevalence of skin infections in individuals with hyperhidrosis compared to others. However, it remains uncertain whether hyperhidrosis is an independent risk factor for skin infections. OBJECTIVE: To compare the risk of skin infections in individuals with and without hyperhidrosis. METHODS: In this retrospective cohort study, data on hyperhidrosis were collected from the Danish Blood Donor Study. Blood donors included in 2010-2019 were followed from inclusion until December 2019. Data on redeemed prescriptions against skin infections were collected from the National Prescription Register. The intensity of prescription-use by hyperhidrosis status was assessed in Andersen-Gill models. RESULTS: Overall, 4,176 (9.6%) of 43,477 blood donors had self-reported hyperhidrosis and 437 (0.34%) of 127,823 blood donors had hospital diagnosed hyperhidrosis. Self-reported hyperhidrosis was associated with the use of antibiotic prescriptions (adjusted hazard ratio = 1.21; 95% confidence interval 1.00-1.45, p = 0.047). Hospital diagnosed hyperhidrosis was associated with the use of antibiotic (adjusted hazard ratio = 1.33; 95% confidence interval 1.03-1.68, p = 0.028) and topical antifungal prescriptions (adjusted hazard ratio = 1.43; 95% confidence interval 1.04-1.97, p = 0.027). CONCLUSIONS: Hyperhidrosis is associated with the use of prescriptions for antibiotics and topical antifungals. This suggests a clinically relevant association between hyperhidrosis and skin infections.

OBJECTIVES: Occupational skin disease (OSD) arises from work-related activity. However, there is a paucity of literature on OSD in physicians. The aim of the this review was therefore to examine and summarize what types of symptomatic OSD physicians experience. METHODS: We conducted a systematic literature search on Cochrane Library, Embase, and Pubmed. RESULTS: Contact dermatitis from formaldehyde and glutaraldehyde were found in 11.5 and 13.5% of cases, respectively. In total 2.4-14.9% had latex allergy. The reported standardized incidence ratio of squamous cell carcinoma and melanoma was up to 2.15 [95% confidence interval (CI) 1.57-1.95] and 3.2 (95% CI 1.38-6.31). Transmission of human papilloma virus (HPV) particles during carbon dioxide laser wart ablation were found in 70% of samples collected from protective gloves and in 52% of samples from vapors. CONCLUSIONS: The most frequently reported OSD in physicians is contact dermatitis from allergens in disinfectants and rubber gloves. There is also a risk of cutaneous reactions to latex. The incidence of skin cancer was higher in physicians than in the general population, and the reason for this remains unexplained and potentially biased. There are no reports of transmission of patient HPV to surgeons during wart ablation, possibly because of proper use of protective equipment.

BACKGROUND: The pathophysiology of xerosis depends on extrinsic and intrinsic exposures. Residential hard water may constitute such an exposure. OBJECTIVES: To estimate the prevalence of xerosis and to compare water hardness exposure in blood donors with and without xerosis. METHODS: In this retrospective cohort study in 2018-2019, blood donors with self-reported moderately or severely dry skin were compared to blood donors without dry skin. Blood donors with ichthyosis, lichen planus and psoriasis were excluded. Water hardness data was collected from the Geology Survey of Denmark and Greenland. RESULTS: Overall, 4,748 of 30,721 (15.5%; 95% confidence interval 15.1-15.9%) blood donors had xerosis. After excluding blood donors with ichthyosis, lichen planus and psoriasis, 4,416 blood donors (2,559 females; median age 38.4 years [interquartile range 28.0-49.8]; 700 smokers) remained in this study. Water softer than 12-24 degrees Deutsche härte was associated with decreased probability of xerosis (odds ratio 0.83; 95% confidence interval 0.74-0.94) and water harder than 12-24 degrees Deutsche härte was associated with increased probability of xerosis (odds ratio 1.22; 95% confidence interval 1.03-1.45). The association between water hardness and xerosis remained significant after excluding blood donors with dermatitis. CONCLUSIONS: Water hardness is associated with xerosis independent of other dermatoses.

Schnitzler syndrome (SS) is a rare autoinflammatory disease that presents with chronic urticaria and monoclonal immunoglobulin (Ig) M or G, accompanied by fever, abnormal bone remodeling, skin biopsy with a neutrophilic dermal infiltrate, leukocytosis, or elevated C-reactive protein. It is usually refractory to antihistamines and immunosuppression. We present a case report of clinical SS without monoclonal Ig with robust response to interleukin-1 inhibitor anakinra. This suggests the possible existence of an incomplete form of SS and underlines the risk of false negative diagnosis in individuals with such "incomplete SS".

PURPOSE: We sought to investigate whether preadmission quality of life could act as a predictor of mortality among patients admitted to the intensive care unit (ICU). MATERIALS AND METHODS: This is a prospective observational study of all patients above the age of 18 years admitted to the ICU with a length of stay longer than 24 hours. Short form 36 (SF-36) and Acute Physiology and Chronic Health Evaluation II (APACHE II) were used. Mortality was assessed during ICU admission, 30, and 90 days hereafter. RESULTS: We included 318 patients. No patients were lost to follow-up. Using the physical component summary of short form 12 (SF-12) as a predictor of ICU mortality, the area under the curve (0.70; confidence interval, 0.62-0.77) was comparable with that of APACHE II (0.74; confidence interval, 0.67-0.82). The difference between SF-12 and SF-36 was nonsignificant. CONCLUSIONS: Preadmission quality of life, assessed by SF-36 and SF-12, is as good at predicting ICU, 30-, and 90-day mortality as APACHE II in patients admitted to the ICU for longer than 24 hours. This indicates that estimated preadmission quality of life, potentially available in the pre-ICU setting, could aid decision making regarding ICU admission and deserves more attention by those caring for critically ill patients.
