Background
Hereditary angioedema (HAE) with normal C1‐INH (HAEnCI) may be linked to specific mutations in the coagulation factor 12 (FXII) gene (HAE‐FXII) or functional mutations in other genes that ...are still unknown. We sought to identify and characterize a hitherto unknown type of HAE with normal C1‐INH and without mutation in the F12 gene.
Methods
The study comprised analysis of whole‐exome sequencing, Sanger sequencing, and clinical data of patients.
Results
We detected a mutation in the plasminogen (PLG) gene in patients with HAEnCI. The mutation c.9886A>G was located in exon 9 leading to the missense mutation p.Lys330Glu (K330E) in the kringle 3 domain of the PLG protein. The mutation was identified by next‐generation sequencing in 14 patients with HAEnCI belonging to 4 of 7 families. Family studies revealed that this type of HAE was transmitted as an autosomal dominant trait. The PLG gene mutation was present in all studied symptomatic patients and was also found in 9 of 38 index patients from 38 further families with HAEnCI. Most patients had swelling of face/lips (78.3%) and tongue (78.3%). A total of 331 of all 3.795 tongue swellings (8.7%) were associated with dyspnea, voice changes, and imminent asphyxiation. Two women died by asphyxiation due to a tongue swelling.
Conclusions
Hereditary angioedema with a mutation in the PLG gene is a novel type of HAE. It is associated with a high risk of tongue swellings.

Background
Dry skin is a frequent and multifaceted condition which can be associated with skin irritation, itch, patient discomfort and manifest skin disease. In spite of being frequent, little is ...known about the epidemiology of dry skin in the population.
Objective
To determine the prevalence of dry skin in the German adult population.
Methods
Data of 48 630 employed persons were assessed on a cross‐sectional level in whole‐body examinations by experienced dermatologists during company‐based skin screenings conducted in 343 German companies. Next to the current dermatologic findings, age, gender, allergies, atopic diseases and the skin type were assessed.
Results
In total, n = 14 300 persons (29.4%) were rated as having xerotic skin. Older age but not gender was associated with xerosis. In the regression analyses controlling for age and gender, dry skin was a significant predictor for: axillary dermatitis (OR: 4.51; CI 2.70–7.54), atopic eczema (OR: 3.99; CI 3.42–4.65), exsiccation eczema (OR: 2.96; CI 2.40–3.65), psoriasis (OR: 1.57; CI 1.38–1.78), plantar warts (OR: 1.42; CI 1.26–1.60), seborrhoeic dermatitis (OR: 1.28; CI 1.16–1.42) and atopic disposition (OR: 1.17; CI 1.12–1.22).
Conclusion
Dry skin is a frequent condition in the adult general population and needs special attention. Known risk factors may facilitate identifying patients at risk for deterioration.

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.
Hereditary angioedema due to C1 inhibitor (C1 esterase inhibitor) deficiency (types I and II HAE-C1-INH) is a rare disease that usually presents during childhood or adolescence with intermittent ...episodes of potentially life-threatening angioedema. Diagnosis as early as possible is important to avoid ineffective therapies and to properly treat swelling attacks. At a consensus meeting in June 2011, pediatricians and dermatologists from Germany, Austria, and Switzerland reviewed the currently available literature, including published international consensus recommendations for HAE therapy across all age groups. Published recommendations cannot be unconditionally adopted for pediatric patients in German-speaking countries given the current approval status of HAE drugs. This article provides an overview and discusses drugs available for HAE therapy, their approval status, and study results obtained in adult and pediatric patients. Recommendations for developing appropriate treatment strategies in the management of HAE in pediatric patients in German-speaking countries are provided.
Conclusion
Currently, plasma-derived C1 inhibitor concentrate is considered the best available option for the treatment of acute HAE-C1-INH attacks in pediatric patients in German-speaking countries, as well as for short-term and long-term prophylaxis.

Summary
Basal cell carcinoma (BCC), also known as rodent ulcer, is the most common type of non‐melanoma skin cancer worldwide. It affects about 3–10% of people. This study from the U.K. and Germany ...aimed to find out if BF‐200 ALA gel would work as well as (is non‐inferior to) the already authorised MAL cream in the treatment of non‐aggressive BCC lesions. Both medications are applied topically (on the skin) to the tumour, which is then illuminated with a certified lamp. The illumination causes a chemical reaction that affects the cancer cells so that they eventually die. This kind of procedure is called photodynamic therapy (PDT). Patients in the study were put into the two groups by chance (randomized): 138 in the BF‐200 ALA group and 143 in the MAL group. The treatment scheme for both drugs was the same. Initially, patients had two PDTs one week apart. Four and 12 weeks after the second PDT, patients visited the doctor again, who assessed the treated lesions and patient's health. If all lesions were gone by week 12, the patient entered the 5‐year follow‐up study. In case of remaining lesions, patients received two more PDTs before entering the follow‐up. During the follow‐up, doctors monitor the health of the patients and assess if any of the treated lesions come back. The study found that there was no difference between the two groups, which means that BF‐200 ALA gel worked as well as the already approved MAL cream. In 113 of 121 patients (93.4%) treated with BF‐200 ALA and 101 of 110 patients (91.8%) treated with MAL, lesions disappeared completely. 87% of the BF‐200 ALA‐treated patients rated their satisfaction with the PDT as “very good or good”; 86% of the MAL‐treated patients said the same. Almost all patients experienced mild to moderate local side effects related to the study medications. Common side effects at the application site, which affected more than 1 of 10 patients, were pain, skin reddening (erythema), itching (pruritus), and tissue swelling (oedema). Side effects were similar for both medications. At 12‐month follow‐up, lesions reappeared in 8.4% of the BF‐200 ALA‐treated patients and in 8.5% of the MAL‐treated patients. The follow‐up is still ongoing; further results will be reported after the end of the study. This study showed that BF‐200 ALA gel is as effective and well‐tolerated as MAL cream in the treatment of non‐aggressive BCC. Based on these findings, the European Medicine Agency (EMA) granted approval for BF‐200 ALA for the treatment of non‐aggressive BCC.
