The correlation between self-reported hand eczema and clinically based diagnosis in professional cleaners.

BACKGROUND: Most studies investigating the prevalence of hand eczema (HE) in professional cleaners use self-reported questionnaire-based data. However, no validation studies of self-reporting of HE among professional cleaners have previously been conducted. OBJECTIVES: To investigate (1) the point prevalence of self-reported HE, (2) the point prevalence of HE estimated by physical examination of the hands and (3) the sensitivity and specificity of self-reporting of HE compared with the diagnosis based on physical examination among professional cleaners. METHODS: Professional cleaners at three different hospitals in Region Zealand were invited to fill out a questionnaire. The point prevalence of self-reported HE was estimated based on questions from the Nordic Occupational Skin Questionnaire. After completing the questionnaire, each cleaner underwent a physical examination of the hands by a dermatologist on the same day. RESULTS: In total, 234 cleaners were invited to participate in the study, and 224 (response rate = 96.0%) agreed to take part. Based on the self-reported questionnaires, 5.3% (n = 12) of the cleaners had current HE. Based on an examination by a physician, 19.2% (n = 43) of the cleaners had current HE. The sensitivity of self-reported HE was found to be 28.0%, while the specificity was found to be 100.0%. The positive predictive value was found to be 100.0%, while the negative predictive value was 85.0%. CONCLUSION: The true point prevalence of HE among professional cleaners is underestimated when based on self-reporting.

Prevalence, risk factors, and prevention of occupational contact dermatitis among professional cleaners: a systematic review.

OBJECTIVE: The aim of this study was to investigate the prevalence, risk factors, and prevention of occupational contact dermatitis (OCD), as well as risk factors and consequences of OCD among professional cleaners. METHODS: A systematic review following PRISMA guidelines was performed using Medline, EMBASE, and Cochrane Library. RESULTS: Thirty-nine studies containing over 109.000 participants were included in the review. The prevalence of OCD varied between 2.2% and 30.1%. Main occupational risk factors for developing OCD among cleaners included wet work and irritants in cleaning products (bleach, chlorine, ammonia, multi-use-cleaning) and skin contact to metal. The most common contact allergies included rubber, biocides, nickel/cobalt, and perfumes. Other risk factors were inconsistent use of protective gloves and low educational level. Consequences associated with OCD included significant impairment in quality of life, tendency to have unscheduled absence from work, sick leave, increased rate of disability, and recognized degree of injury. Only one prevention study has been published investigating the effect of an educative course in skin-protective behavior in cleaners. The study reported a higher degree of knowledge of skin protection, a decrease in the severity of hand eczema, and a shift toward fewer daily hand washings at follow-up after 3 months. CONCLUSION: Our study proves that OCD is common in cleaners, and the main risk factors included wet work, irritants, and contact allergies, as well as inconsistent use of protective gloves and low educational level. More focus and a greater number of studies are needed on skin protection in this population.

What do professional cleaners know about the skin care? A questionnaire-based study.

BACKGROUND: Correct daily skin care is important regarding hand eczema (HE). However, only a few studies have evaluated the level of knowledge among hospital cleaners. OBJECTIVE: To examine the level of knowledge regarding skin protective behaviour and risk factors with respect to HE in hospital cleaners. METHODS: All cleaners working in four hospitals in Denmark were invited to participate in the study, which was based on a questionnaire consisting of 22 questions. RESULTS: 142 of 236 cleaners (response rate = 60.1%) were included. The mean of total correct answers were approximately five out of nine questions. 85.6% of participants evaluated themselves to have a low degree of knowledge of skin care and protection. Based on the number of correct answers, 90% were defined as having low knowledge. Being born or raised outside of Denmark was statistically significantly associated with lower level of knowledge. Risk factors for HE such as, work with wet hands, and use of household cleaning products were only recognized as risk factors by less than 50%. CONCLUSION: Our study indicates that Danish hospital cleaners have a low degree of knowledge regarding skin care and protection. Cleaning workers born or raised outside of Denmark are in need of special attention.

Prevalence and risk factors for hand eczema among professional hospital cleaners in Denmark: A cross-sectional questionnaire-based study.

BACKGROUND: Professional cleaners are commonly affected by hand eczema (HE) due to wet work and exposure to cleaning products in the work environment. OBJECTIVE: To investigate (1) the prevalence of HE in a group of professional hospital cleaners, (2) the association of HE with various comorbidities and self-reported signs/symptoms of skin lesions and (3) the association of HE with various occupational and personal risk factors in the same population. METHODS: A cross-sectional questionnaire-based study including all cleaners working in three hospitals in Denmark. The questionnaire was composed of 35 questions. Prevalence is reported using proportions with 95% confidence intervals and compared using difference of proportions and Fisher's exact test. RESULTS: A total of 122 out of 180 cleaners (response rate = 68%) participated in this study. The self-reported lifetime prevalence of HE among the cleaners was 30.3%, while the 1-year prevalence was 18.9%. HE was significantly associated with a history of atopic diseases. There was a significant correlation between having HE, and self-reported redness and itch of the hands in the last 12 months, as well as the use of hydrochloric acid ≥4 days/week during the last 12 months. Logistic regression analysis found HE significantly associated with washing hands ≥20 times during a working day and a history of atopic dermatitis. CONCLUSION: Cleaners are at an elevated risk of developing HE. More focus on education/information regarding the prevention and treatment of HE is necessary for the cleaning profession. Self-reported redness and itching of the hands may be a useful prediction of HE in cleaners.

Clinical Importance of Superior Sensitivity of the Aptima TMA-Based Assays for Mycoplasma genitalium Detection.

Mycoplasma genitalium (MG) is a common cause of nongonococcal cervicitis and urethritis. We investigated the demographic and clinical characteristics of patients tested in Denmark with the Conformité Européenne (CE)/in vitro diagnostics (IVD) Aptima Mycoplasma genitalium assay (CE/IVD AMG; Hologic) and examined the clinical significance of the higher sensitivity of the TMA-based MG assays. From March to June 2016, urogenital and extragenital specimens from consecutive attendees at a sexually transmitted infection clinic in Copenhagen, Denmark were tested with the CE/IVD AMG assay (TMA-based), the research-use-only MG Alt TMA-1 assay (Hologic), a laboratory-developed TaqMan mgpB quantitative real-time PCR (qPCR), and the Aptima Combo 2 (CT/NG; Hologic). Demographic characteristics and clinical symptoms were collected from the patient records. There were 1,245 patients included in the study. The MG prevalence among female subjects was 9.4%, and the MG prevalence among male subjects was 8.7%. Compared to the TMA-based assays, the sensitivity of the PCR-based MG assay was 64.52%, and 55 specimens from 48 individuals were missed in the mgpB qPCR. Of these, 26 individuals (54.2%) were symptomatic, whereas, among 64 individuals with concordant results, 30 individuals (46.9%) were symptomatic; no statistically significant difference was found between the groups (P = 0.567). The improved sensitivity of the TMA-based assays resulted in diagnoses of more patients with clinically relevant symptoms for which antibiotic treatment is indicated. However, approximately half of the MG-infected patients reported no symptoms, and future research is needed to investigate the pros and cons of diagnosing and treating MG in asymptomatic subjects.

Alopecia areata.

Alopecia areata (AA) is an autoimmune disease where inflammation around the lowest part of the hair follicle results in non-scarring hair loss. This review investigates the course of the disease, its unpredictability and variation from a single patch of scalp hair loss to the loss of all hair on the body. The first drug with AA indication was approved in 2022, the JAK-inhibitor baricitinib. This paves the way for future research that may lead to the development of new effective pathogenesis-specific treatments.

Communicating with patients through pictograms and pictures - a scoping review.

BACKGROUND: Communication between patients and healthcare workers (HCWs) may on occasion be challenged by disparities in cultural background, age and educational level. Written educational material is commonly used to reduce the risk of miscommunication. However, literacy among patients may also differ and it is, therefore, speculated that the use of pictograms may improve patients' understanding and adherence. OBJECTIVE: To evaluate the scientific literature and investigate the effect and practical utility of pictograms in medical settings with focus on dermatological patients. MATERIALS AND METHODS: Pubmed, EMBASE, and Cochrane Library were searched July 2021 for studies regarding use of pictograms in medical settings and dermatology. RESULTS: The use of pictograms in dermatology is not well characterized, but studies in other fields of medicine report a positive effect of using pictograms in communication. Pictograms have a significant positive effect when presented alongside verbal or written explanations. CONCLUSIONS: The quality of the development process is important to ensure the utility of any pictogram. Involving the target population in the design and validation of the pictograms may be critical. In the validation process, testing of transparency and translucency may benefit from international recommendations.

The impact of dysfunctional breathing on the level of asthma control in difficult asthma.

BACKGROUND: Difficult asthma is defined as asthma requiring high dose treatment. However, systematic assessment is required to differentiate severe asthma from difficult-to-treat asthma. Dysfunctional breathing (DB) is a common comorbidity in difficult asthma, which may contribute to symptoms, but how it affects commonly used measures of symptom control is unclear. METHODS: All adult asthma patients seen in four respiratory clinics over one year were screened prospectively, and patients with possible severe asthma according to ERS/ATS criteria ('Difficult asthma': high-dose inhaled corticosteroids/oral corticosteroids), underwent systematic assessment. Symptoms of DB were assessed utilizing a symptom based subjective tool, Nijmegen questionnaire (NQ), and objective signs of DB with the Breathing Pattern Assessment Tool (BPAT). Asthma control and quality of life were evaluated with the Asthma Control Questionnaire (ACQ) and the mini Asthma Quality of Life Questionnaire (AQLQ). RESULTS: A total of 117 patients were included. Among these, 29.9% (35/117) had DB according to the NQ. Patients with DB had a poorer asthma control (ACQ: Mean (SD) 2.86 ± 1.05 vs. 1.46 ± 0.93) and lower quality of life (AQLQ score: Mean (SD) 4.2 ± 1.04 vs. 5.49 ± 0.85) compared to patients without DB. Similarly, patients with objective signs of DB according to the BPAT score had worse asthma control: BPAT >4 vs < 4: (ACQ: Mean (SD) 3.15 ± 0.93 vs 2.03 ± 1.15). CONCLUSION: DB is common among patients with difficult asthma, and is associated with significantly poorer asthma control and lower quality of life. Assessment and treatment of DB is an important part of the management of difficult asthma.

Prevalence of neovascular age-related macular degeneration and geographic atrophy in Denmark.

INTRODUCTION: In Denmark, age-related macular degeneration (AMD) is the most common cause of blindness. To better understand current and future challenges, we estimated and projected the annual number of patients with neovascular AMD and geographic atrophy in Denmark from 2016 to 2060. METHODS: Detailed age- and gender-stratified prevalence estimates of neovascular AMD and geographic atrophy in a Scandinavian population were identified and applied to age- and gender-stratified population numbers provided by Statistics Denmark. Prevalence estimates were calculated for each year from 2016 to 2060. Future forecasts were provided by Statistics Denmark and based on calculations by the Danish Institute for Economic Modelling and Forecasting. RESULTS: We estimated that there are currently ~30,000 patients with neovascular AMD and ~21,000 patients with geographic atrophy in Denmark. The majority of these patients are persons aged ≥ 85 years. For neovascular AMD, the number of patients will grow to ~33,000 in 2020, ~58,000 in 2040 and ~72,000 in 2060. For geographic atrophy, the number of patients will grow to ~23,000 in 2020, ~41,000 in 2040, and ~50,000 in 2060. CONCLUSIONS: We expect a steady growth in the prevalence of neovascular AMD and geographic atrophy in Denmark due to an ageing population. These numbers emphasise the importance of disease prevention, careful planning of health service activities and continuing research. FUNDING: none. TRIAL REGISTRATION: not relevant.
