RESUMEN
BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease with a multifactorial genesis including genetic predispositions and environmental risk and trigger factors. One of the latter possibly is smoking, indicated by an increased prevalence of AD in adults and children that are actively or passively exposed to cigarette smoke. OBJECTIVES: In this study, AD characteristics and its atopic comorbidities are compared in smoking and non-smoking AD patients. METHODS: TREATgermany is a non-interventional clinical registry which includes patients with moderate to severe AD in Germany. Baseline data of patients included in TREATgermany from inception in June 2016 to April 2020 in 39 sites across Germany was analysed comparing AD disease characteristics and comorbidities in smokers vs. non-smokers. RESULTS: Of 921 patients, 908 (male: 58.7%) with a mean age of 41.9 ± 14.4 reported their smoking status. The objective Scoring of Atopic Dermatitis (oSCORAD) did not differ between smokers (n = 352; 38.8%) and non-smokers, however, lesions' intensity of oozing/crusts and excoriations as well as patient global assessment scores (PGA) of AD severity were higher in smoking as opposed to non-smoking patients. Smokers reported a lower number of weeks with well-controlled AD and more severe pruritus than non-smokers. Total IgE levels were more elevated in smokers and they displayed a younger age at the initial diagnosis of bronchial asthma. After adjustment for potential confounders, the increased intensity of oozing/crusts, the reduced number of weeks with well-controlled AD and the greater pruritus remained different in smokers compared to non-smokers. In addition, smoking patients with adult-onset AD showed a 2.5 times higher chance of involvement of the feet. CONCLUSIONS: German registry data indicate that AD patients who smoke have a higher disease burden with a different distribution pattern of lesions in adult-onset AD.

BACKGROUND: Outdoor workers are occupationally exposed to significantly higher ultraviolet (UV) doses than the rest of the population. Recent data show a doubling of basal cell carcinoma (BCC) risk in outdoor workers with high occupational UV exposure. OBJECTIVES: To examine the stability and robustness of BCC risk estimators. METHODS: Sensitivity analyses to test model assumptions considering socioeconomic status, influence of matching procedure, gender and latency, regional differences (east/west), urban/rural cases/controls, and dual diagnoses (squamous cell carcinoma [SCC]/actinic keratoses grade III [AKIII]/Bowen disease [BD] and BCC) were performed. RESULTS: BCC risk was consistently higher for high occupationally UV-exposed individuals than for intermediate UV-exposed individuals, regardless of matching procedure, latency, regional differences (east/west), urban/rural recruitment of cases/controls, and dual diagnoses (SCC/AKIII/BD and BCC), sex, and socioeconomic status. CONCLUSION: The risk estimator for the association between exposure to solar UV radiation at work and the risk of developing BCC showed a high degree of stability and robustness for all variables investigated. The analyses support the recently published findings on the doubling of BCC risk in outdoor workers with high occupational UV exposure.

BACKGROUND: The Atopic Dermatitis (AD) TREATgermany registry was initiated by the German Society for Dermatology (DDG) in 2011 to evaluate the 'real-life' situation of health care for patients with AD. OBJECTIVES: Interim data analysis on baseline characteristics as well as current and prescribed systemic treatments of the TREATgermany registry patients. METHODS: Patients (≥18 years) with moderate-to-severe AD [objective (o)SCORAD > 20], or with current or previous anti-inflammatory systemic treatment for AD within 24 months, were included and are followed up over at least 24 months. To assess clinical signs, the eczema area severity index (EASI, 0-72), the oSCORAD (0-83) and the Investigator Global Assessment (IGA; 6-point scale) were used. The disease severity was globally scored by the patients [Patient Global Assessment (PGA); six-step Likert scale]. Disease symptoms were assessed by the patient-oriented eczema measure (POEM, 0-28) and numeric rating scales (NRS, 0-10). Health-related quality of life was measured using the dermatological life quality index (DLQI, 0-30). RESULTS: A total of 612 patients were recruited across 32 sites between 06/2016 and 01/2019 (mean age: 42.6 ± 14.2 years; mean oSCORAD: 40.8 ± 16.3). The mean POEM score was 16.3 ± 7.5. Pruritus was rated highest among subjective symptoms (NRS: 5.4 ± 2.7). The mean DLQI value was 11.3 ± 7.5. The frequency of arterial hypertension was lower (20.8%) compared with the general population, whilst this was higher for depression (10%). More than 60% of the patients had received systemic glucocorticosteroids, and 36.8% had received cyclosporine A prior to inclusion. Dupilumab was the leading substance documented as either 'current' (12.1%) or 'prescribed' (31.4%) at baseline. CONCLUSIONS: These 'real-life' data clearly demonstrate the substantial disease burden. Most of TREATgermany patients were already treated with or prescribed dupilumab at baseline. Moreover, current findings indicate the urgent need for further alternative agents in order to achieve a perceptible improvement of quality of life of patients with moderate-to-severe AD.

BACKGROUND: Squamous cell carcinoma (SCC) is one of the most frequent types of cancer constituting a significant public health burden. Prevention strategies focus on limiting ultraviolet (UV) exposure during leisure time. However, the relative impact of occupational and nonoccupational UV exposure for SCC occurrence is unclear. OBJECTIVES: To investigate the association between occupational and nonoccupational UV exposure for SCC in a multicentre population-based case-control study hypothesizing that high occupational UV exposure increases the risk of SCC. METHODS: Consecutive patients with incident SCC (n = 632) were recruited from a German national dermatology network. Population-based controls (n = 996) without history of skin cancer were recruited from corresponding residents' registration offices and propensity score matched to cases. Lifetime UV exposure, sociodemographic and clinical characteristics were assessed by trained physicians. Occupational and nonoccupational UV exposure doses were estimated by masked investigators using established reference values. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were assessed using conditional logistic regression adjusting for relevant confounders. RESULTS: Total solar UV exposure was significantly associated with increased SCC. The OR for high (> 90th percentile) vs. low (< 40th percentile) and high vs, moderate (40-59th percentile) occupational UV exposure was 1·95 (95% CI 1·19-3·18) and 2·44 (95% CI 1·47-4·06) for SCC. Adjusting for occupational UV exposure, nonoccupational UV exposure was not significantly related to SCC incidence. Dose-response relationships were observed for occupational but not for nonoccupational solar UV exposure. CONCLUSIONS: Solar occupational UV exposure is a major determinant of incident SCC. Our findings indicate that prevention strategies should be further expanded to the occupational setting.

BACKGROUND: Clinical registries may provide high-quality evidence on the use and effectiveness of therapeutic interventions under real-life conditions. Adults with moderate-to-severe atopic eczema (atopic dermatitis [AD]) are enrolled into TREATgermany and prospectively followed over at least 2 years. This paper analyses the association between dermatological quality of life and work limitations. MATERIALS AND METHODS: Treatment modalities and a broad set of physician- and patient-reported outcome measures are documented using validated instruments to assess clinical disease severity (EASI [Eczema Area and Severity Index], objective SCORAD [objective-SCORing Atopic Dermatitis]), quality of life (DLQI [Dermatology Life Quality Index]), symptoms (POEM [Patient-oriented Eczema Measure]), global disease severity, as well as patient satisfaction and work limitations including presenteeism (WLQ [Work Limitation Questionnaire]). From 06/2016 until 12/2017, 241 individuals (mean age 43⯱ 15 years, 38.6% female) were enrolled at 19 recruitment centers; 69% of the patients were employed. RESULTS: Employed persons had DLQI and WLQ scores of 10.6⯱ 6.9 points and 17.7⯱ 18.1%, respectively. Mean presenteeism was substantial accounting for 9.2%. With coefficients of 0.39 and 0.33 WLQ and presenteeism scores significantly correlate with DLQI (pâ¯< 0.000). Bootstrapped regression models showed that the limitations in coping with work requirements increase by 1.7% as DLQI increases by one point. Lower quality of life due to AD is most strongly associated with limitations in the area of physical and performance requirements in general. Presenteeism increases by 0.5% as DLQI increases by one point. CONCLUSION: Moderate-to-severe AD has substantial adverse economic impact with mean productivity loss of patients of almost 10%. Future analyses from TREATgermany will address the impact of innovative treatment modalities on quality of life and work productivity of patients with moderate-to-severe AD.

Dermatologists may choose from various conventional and biological systemic agents to treat patients with moderate-to-severe psoriasis. We set out to analyse systematically the efficacy and tolerability of approved treatments for moderate-to-severe psoriasis. We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating the efficacy of systemic treatment approved for moderate-to-severe psoriasis. Efficacy was assessed as the proportion of participants with 75% improvement in Psoriasis Area and Severity Index at primary efficacy measurement (week 8-16). Safety was summarized as rates of adverse events and withdrawals. Direct and indirect comparative efficacy was assessed by random effects meta-analysis of risk differences (RDs). In total, 48 eligible RCTs totalling 16 696 patients (11 178 randomized to biologics, 1888 to conventional treatments) were identified. In placebo-controlled trials, infliximab was the most efficacious [RD 76%, 95% confidence interval (CI) 73-79%]. Adalimumab (RD 61%, 95% CI 56-67%), and ustekinumab 45 mg (RD 63%, 95% CI 59-66%) and 90 mg (RD 67%, 95% CI 60-74%) each had similar efficacy. These biologics are more effective than etanercept and all conventional treatments. Head-to-head trials indicate the superiority of adalimumab and infliximab over methotrexate (MTX), the superiority of ustekinumab over etanercept, the nonsignificant superiority of ciclosporin over MTX, and the dose-dependent efficacy of etanercept and ustekinumab. Fumaric acid is as efficacious as MTX. Safety of treatments could not be pooled due to a lack of standardization in reporting across trials. In conclusion, the qualitative and quantitative evidence is much stronger for biological interventions than for conventional treatments.

BACKGROUND: A two-fold risk increase to develop basal cell carcinoma was seen in outdoor workers exposed to high solar UV radiation compared to controls. However, there is an ongoing discussion whether histopathological subtype, tumor localization and Fitzpatrick phototype may influence the risk estimates. OBJECTIVES: To evaluate the influence of histological subtype, tumor localization and Fitzpatrick phototype on the risk to develop basal cell carcinoma in highly UV-exposed cases and controls compared to those with moderate or low solar UV exposure. METHODS: Six hundred forty-three participants suffering from incident basal cell carcinoma in commonly sun-exposed anatomic sites (capillitium, face, lip, neck, dorsum of the hands, forearms outside, décolleté) of a population-based, case-control, multicenter study performed from 2013 to 2015 in Germany were matched to controls without skin cancer. Multivariate logistic regression analysis was conducted stratified for histological subtype, phototype 1/2 and 3/4. Dose-response curves adjusted for age, age2, sex, phototype and non-occupational UV exposure were calculated. RESULTS: Participants with high versus no (OR 2.08; 95% CI 1.24-3.50; p = 0.006) or versus moderate (OR 2.05; 95% CI 1.15-3.65; p = 0.015) occupational UV exposure showed a more than two-fold significantly increased risk to develop BCC in commonly UV-exposed body sites. Multivariate regression analysis did not show an influence of phototype or histological subtype on risk estimates. The restriction of the analysis to BCC cases in commonly sun-exposed body sites did not influence the risk estimates. The occupational UV dosage leading to a 2-fold increased basal cell carcinoma risk was 6126 standard erythema doses. CONCLUSION: The risk to develop basal cell carcinoma in highly occupationally UV-exposed skin was doubled consistently, independent of histological subtype, tumor localization and Fitzpatrick phototype.
RESUMEN
This article deals with the special demands on occupational medicine due to the changes of work and of tasks at workplaces. Conclusions for research in occupational medicine are drawn from these processes. They are discussed on the basis on an analysis of literature from the years 1980-1998. Focus of future research in the field of occupational medicine is developed by taking international tendencies, the interdisciplinary setting of occupational medicine, and the close relations between science and practice into consideration.

After oral administration of 300 mg Sobelin, the efficacy and pharmacological kinetics of clindamycin (CAS 18323-44-9) were analysed in 35 patients with recurrent tonsillitis. Minimal inhibitor concentration (MIC) and minimal bactericidal concentration (MBC) have been evaluated for 120 strains. MIC and MBC for 91.7% of the strains amounted to 0.25 micrograms/ml. Concentrations of antibiotics in the serum were higher than 0.25 micrograms/ml after 12 h, i.e. higher than the minimal inhibitory concentration. The established free and efficient portion of clindamycin in the serum which is not bound to plasma proteins shows that a clear bacteriostatic effect is achieved up to 6 h after application of the antibiotic. The concentration in the tissue of the tonsils was 0.6-0.8 micrograms/g after 7-9 h indicating that sufficient MIC values were achieved. The free portion of the antibiotic in the tissues after 9 h also reached the MIC of germs. Hence clindamycin is considered to be an efficient antibiotic in the management of acute exacerbation of recurrent tonsillitis. Due to serum- and tissue levels of the tonsils administration of 300 mg of the test drug is indicated three times daily.
