ABSTRACT

Perioperative anaphylaxis occurs in about 1:6000 of all surgical procedures. Recently, the pathophysiology of anaphylactic reactions via mast cell related G-protein und complement-activated pseudo-allergy have been added to the "old" IgE mediated etiology. New culprits for anaphylactic reactions are chlorhexidine or gelatine as hemostypticum or blue surgical dyes to mark the situs. Biphasic anaphylactic reactions should be kept in mind. In the meantime, propofol use is allowed in egg and soybean allergic patients.

ABSTRACT

Anaphylactic reactions following vaccination are rare. However, anaphylactic reactions towards the Pfizer-BioNTech Covid-19 vaccine were first reported in two patients in the UK and another 19 in the USA. Pegylation with polyethylene glycol (PEG) was thought to be the possible culprit. Pegylation is a common process in the manufacture of vaccines in order to prevent early degradation by the immune system. PEG is a polyether like e. g. Laureth-9, polidocanol, thesit and macrogol and is found in foodstuffs, cosmetics and personal care products as well as in liposomes and nanoparticles, as drug-delivery-system and as osmotic laxans for gastroscopies/coloscopies. Given the widespread use of PEG, reactions to vaccinations are rare and therefore no reason to exclude allergic patients in principle or indeed those who know the exact cause of a former anaphylaxis. In Germany, medical doctors are obliged to report any severe adverse reactions following vaccination; it is hoped that this procedure will help to resolve any remaining questions.

ABSTRACT

BACKGROUND: Treatment of moderate-to-severe atopic dermatitis (AD) can be challenging and little is known about the sustainability of on- and off-label prescribed systemic therapies. OBJECTIVES: To compare drug survival (DS) rates and reasons for drug discontinuation of cyclosporine A (CyA), dupilumab (DUP), azathioprine (AZA), methotrexate (MTX) and mycophenolate mofetil (MMF) prescribed under real-world conditions. MATERIALS & METHODS: In this retrospective study, 139 treatment courses for 94 adults with AD treated at two German dermatology departments were analysed. RESULTS: Based on Cox regressions with CyA as reference category, hazard ratios for treatment discontinuation were 0.10 for DUP, 0.87 for MTX, 0.98 for MMF, and 1.18 for AZA. CyA, AZA, and MTX were most frequently interrupted due to adverse events, and MMF due to non-compliance. Only one patient (6.3%) discontinued DUP before the end of the observation period, which was due to ineffectiveness. CONCLUSION: Systemic therapies for AD differ with regards to DS and reasons leading to treatment withdrawal; this should be considered in real-life practice.

ABSTRACT

PURPOSE: Uveal melanoma (UM) is an orphan cancer of high unmet medical need. Current patterns of care and surveillance remain unclear as they are situated in an interdisciplinary setting. METHODS: A questionnaire addressing the patterns of care and surveillance in the management of patients with uveal melanoma was distributed to 70 skin cancer centers in Austria, Germany and Switzerland. Frequency distributions of responses for each item of the questionnaire were calculated. RESULTS: 44 of 70 (62.9%) skin cancer centers completed the questionnaire. Thirty-nine hospitals were located in Germany (88.6%), three in Switzerland (6.8%) and two in Austria (4.5%). The majority (68.2%) represented university hospitals. Most patients with metastatic disease were treated in certified skin cancer centers (70.7%, 29/41). Besides, the majority of patients with UM were referred to the respective skin cancer center by ophthalmologists (87.2%, 34/39). Treatment and organization of follow-up of patients varied across the different centers. 35.1% (14/37) of the centers stated to not perform any screening measures. CONCLUSION: Treatment patterns of patients with uveal melanoma in Germany, Austria and Switzerland remain extremely heterogeneous. A guideline for the treatment and surveillance is urgently needed.

ABSTRACT

Topical hormonal treatment allows anti-aging of the skin when used during and after the menopause without an increase in the blood level of hormones. Natural hormones are only prescribed by medical doctors. In controlled clinical studies versus placebo and application for months, an increase in skin quality parameters, reduction of dryness, increase of glycosaminoglycanes, increase in elastic fibers und increase of collagen precursers and collagen fibers on the mRNA and protein level could be shown, the latter proven by biopsies. Skin with dramatic sun-damage does not respond to this treatment option. Patients with melasma or seborrhoe should not be treated with hormonal topical preparations. Compared to the natural hormones, phytotherapeutics do not bind to hormone receptors in relevant levels. Growth hormones should not be used in anti-aging treatment due to a potential carcinogenic effect.

ABSTRACT

Hymenoptera venom allergy is the most common cause of anaphylactic reactions in adults. In children, it is the second most common cause after food-related anaphylaxis. Such reactions are primarily due to stings by honeybees (Apis) and certain social wasps (Vespula vulgaris and Vespula germanica in particular). Especially in adults, stings are frequently associated with severe anaphylaxis. Established diagnostic methods including molecular tests allow for greater success rates in terms of determining the insect actually responsible for triggering the anaphylactic reaction. Sensitization to both venoms, or a history of systemic sting reaction without any evidence of sensitization, complicate the decision regarding treatment. Venom immunotherapy (VIT) is a safe and effective causal treatment.

ABSTRACT

BACKGROUND: Hyaluronic acid (HA) filler injection is an increasingly popular aesthetic procedure. OBJECTIVE: To compare the effectiveness and safety of two HA fillers (HAED and HAPER) for the treatment of severe nasolabial folds (NLFs). MATERIALS AND METHODS: This was an evaluator-blinded and subject-blinded split-face study. At baseline, HAED or HAPER was randomly assigned to the left or right NLF. The follow-up period was 12 months. Effectiveness was assessed using the wrinkle severity rating scale (WSRS) and subject preference. Safety was assessed by adverse events and local tolerability symptoms recorded by subjects during 3 weeks after the treatment. RESULTS: At 6 months, HAED was noninferior to HAPER (assessed by mean change from baseline in WSRS score). There was a significant difference in mean WSRS score change from baseline in favor of HAED at 3 to 12 months, and a majority of subjects preferred HAED over HAPER at 12 months. However, the overall responder rate was similar between products, and it remained high throughout the study. At 12 months, approximately 80% of subjects were still responders. Both products were well tolerated and associated with a few treatment-related adverse events. CONCLUSION: To conclude, HAED was at least as effective and well tolerated for the treatment of severe NLFs as HAPER.

ABSTRACT

BACKGROUND: Hyaluronic acid (HA) filler injection is a popular nonsurgical aesthetic procedure. OBJECTIVE: To compare the effectiveness and safety of 2 hyaluronic acid fillers (HAEC and HARES) for treatment of moderate nasolabial folds (NLFs). MATERIALS AND METHODS: This was an evaluator- and subject-blinded split-face study. HAEC or HARES was randomly assigned to the left or right NLF at baseline. Retreatment was performed after 9 months; follow-up extended to 18 months after baseline (9 months after retreatment). Effectiveness assessments included the Wrinkle Severity Rating Scale (WSRS) and subject preference. Safety assessments included adverse events (AEs) and local tolerability symptoms recorded by subjects during 3 weeks after treatment. RESULTS: HAEC was noninferior to HARES measured as mean change from baseline in WSRS score at 6 months. Mean WSRS score change from baseline was similar between products up to 18 months. A majority of subjects (>70%) were still responders at 18 months (after retreatment at 9 months). The volume required at retreatment was approximately two-thirds of that at baseline. There was no difference in subject preference between products. Both fillers were well tolerated and associated with few treatment-related AEs. CONCLUSION: HAEC and HARES were effective and well tolerated for treatment of moderate NLFs.

ABSTRACT

BACKGROUND: No consistent data are available on the currently employed diagnostic tools for autoimmune bullous diseases in Germany. The aim of this survey was to describe currently performed diagnostic methods for bullous autoimmune diseases in German dermatology departments. METHODS: A standardized questionnaire evaluated the available diagnostic methods i. e. direct immunofluorescence microscopy (IFM), indirect IFM, commercial ELISA systems, and non-commercial serological tests as well as the number of samples per year in all 34 university and 39 non-university dermatology departments. RESULTS: The overall return rate was 89 %, 100 % and 79 % for the university and non-university departments, respectively. Direct IFM was the most frequently used method and was applied in 98 % of the responding departments. In 74 % of the responding departments, indirect IFM was used mainly on monkey esophagus and human salt-split skin. Commercial ELISA systems were employed in 58 % of the clinics; all of them used anti-desmoglein ELISA, while anti-BP180 and anti-BP230 ELISA were established in 49 % and 48 % of departments, respectively. Non-commercial analytic methods were only performed in 22 % of the departments. CONCLUSIONS: The high return rate of this survey allows a relatively precise description of the current diagnostic methods used in German dermatology departments. Standard diagnostic tests are available nationwide and in bullous pemphigoid and pemphigus, the antigen-specific detection of autoantibodies is routinely performed in half of the departments. Rare disorders may be diagnosed by cooperation with some specialized centers.

ABSTRACT

BACKGROUND: Hyaluronic acid (HA) fillers are frequently used for the correction of facial soft tissue defects. AIM: To compare the efficacy and safety of a novel HA filler, HA(E) (Emervel Deep), with those of HA(P) (Restylane Perlane) in the treatment of severe nasolabial folds (NLF). PATIENTS/METHODS: A split-face, randomized and evaluator-blinded comparison study. Subjects were randomized to receive injection of HA(E) or HA(P) on their left or right NLF. Efficacy was evaluated based on the change in Wrinkle Severity Rating Scale (WSRS) from baseline. Local tolerability was assessed based on subject diary during the first 3 weeks after injection. Adverse events were also evaluated. RESULTS: At both weeks 12 and 24, the mean improvement in WSRS from baseline was significantly greater for HA(E) than for HA(P) (1.58±0.89 vs. 1.33±0.82 at week 24; P=0.002). Similar volume of both products was injected at baseline and touch-up. Both fillers were well tolerated, with similar worst score distribution and mean score for erythema, edema/swelling, bruising, and pruritus. Significantly less severe pain/tenderness was reported with HA(E) than with HA(P) (P<0.05). CONCLUSIONS: The new HA filler HA(E) provides better efficacy and similar local tolerability compared with HA(P) 6 months after the treatment of severe NLF.

ABSTRACT

BACKGROUND: Hyaluronic acid (HA) fillers such as Restylane(®) are frequently used for the correction of facial soft tissue defects. OBJECTIVE: To compare the efficacy and safety of a novel HA filler, Emervel(®) Classic, with those of Restylane in the treatment of moderate nasolabial folds. METHODS: This was a split-face, randomized and evaluator-blinded comparison study. Subjects were randomized to receive an injection of Emervel Classic or Restylane on their left or right side. Efficacy was evaluated based on the change in Wrinkle Severity Rating Score (WSRS) from baseline. Local tolerability was assessed based on subject diary, which recorded the severity of erythema, oedema/swelling, bruising, pain/tenderness and pruritus during the first 3 weeks after injection. RESULTS: The interim results 6 months after injection are reported. At week 24, the mean improvement in WSRS from baseline was 0.83 ± 0.51 for Emervel Classic, similar to that for Restylane (0.90 ± 0.57). A similar volume of both fillers was injected. Most local tolerability events were mild and transient. Erythema, oedema/swelling and pain/tenderness were significantly less severe and disappeared faster with Emervel Classic than with Restylane (at least p < 0.05). CONCLUSION: Emervel Classic provides similar efficacy and better overall local tolerability compared with Restylane 6 months after treatment of moderate nasolabial folds.

ABSTRACT

To optimize the treatment of acne in Germany, the German Society of Dermatology (DDG) and the Association of German Dermatologists (BVDD) initiated a project to develop consensus-based guidelines for the management of acne. The Acne Guidelines focus on induction therapy, maintenance therapy and treatment of post-acne scarring. They include an evaluation of the most commonly used therapeutic options in Germany. In addition, they offer detailed information on how to administer the various treatments and on contraindications, adverse drug reactions, and drug interactions, taking into account gender and special conditions such as pregnancy and lactation. The Acne Guidelines were developed following the recommendations of the Association of Scientific Medical Societies in Germany (AWMF). The treatment recommendations were developed by an expert group and finalized by an interdisciplinary consensus conference. The first choice treatments for acute acne according to acne type are as follows: 1) comedonal acne: topical retinoids; 2) mild papular/pustular acne: fixed or sequential combinations of BPO and topical retinoids or of BPO and topical antibiotics; 3) moderate papular/pustular acne: oral antibiotic plus BPO or plus topical retinoid, or in a fixed combination 4) acne papulo-pustulosa nodosa and acne conglobata: oral antibiotic plus topical retinoid plus BPO or oral isotretinoin. For maintenance treatment: topical retinoid or its combination with BPO. Particular attention should be paid to compliance and quality of life. Additional treatment options are discussed in the main body of the text.

ABSTRACT

OBJECTIVE: Results from previous studies suggest that past trauma experience increases the risk for medically unexplained somatic symptoms and somatoform disorders (SFD). This cross-sectional study examined the link between various lifetime traumas, idiopathic environmental intolerance (IEI), and SFD. METHODS: Two clinical groups of 54 subjects with IEI and 44 subjects with SFD were compared to 54 subjects (comparison group, CG) free from both IEI and SFD regarding self-reported traumas. The subjects were mainly recruited via advertisements in local newspapers. From 970 individuals screened for IEI and multiple somatic symptoms, 152 were included through a two-step selection procedure consisting of screening questionnaires, a medical examination, and structured interviews for IEI and mental disorders. RESULTS: In all three groups at least one potential traumatic event was reported rather frequently (CG: 70%; IEI: 82%; SFD: 73%). But contrary to our expectation, significant group differences were neither found in regard to the proportion of subjects with any trauma, nor traumas fulfilling DSM-IV criteria (CG: 41%; IEI: 48%; SFD: 59%), nor multiple traumas (CG: 43%, IEI: 56%, SFD: 39%). Only two trauma categories were endorsed more frequently by the two clinical groups than by the CG: the unspecified 'other' category (IEI, SFD>CG) and 'life-threatening illness' (IEI>CG). CONCLUSION: No clear evidence was found for increased rates of trauma experience in IEI and SFD. However, the results of this exploratory study should be considered as preliminary. Comparing larger IEI and SFD groups with a representative population-based sample may yield different results.

ABSTRACT

BACKGROUND: Previous studies suggest that idiopathic environmental intolerance (IEI) is a variant of somatoform disorders (SFDs) or the so-called functional somatic syndromes. Little is known, however, about the stability and the psychological predictors of IEI. METHOD: This prospective study examined the 1-year stability of somatic symptoms and IEI features in three diagnostic groups: 49 subjects with IEI, 43 subjects with SFD but without IEI, and 54 subjects (control group, CG) with neither IEI nor SFD. The predictive value of typical psychological predictors for somatization was tested using zero-order correlations and multiple linear regression analyses. RESULTS: Somatic symptoms and IEI features proved to be temporally stable over the 1-year follow-up period. The SFD and IEI groups scored significantly higher than CG on all measures of somatic symptoms and on questionnaires assessing psychological predictors for somatization. Measures of trait negative affectivity (NA), somatic symptom attribution and somatosensory amplification predicted somatic symptom severity within the IEI and SFD groups, both at baseline and 1 year later. The strongest predictors of IEI complaints in the IEI group were somatic attributions, followed by prominent cognitions of environmental threat and a tendency to focus on unpleasant bodily sensations and to consider them as pathological. CONCLUSIONS: IEI and SFD are highly stable conditions. In both SFD and IEI, NA and the processes of symptom perception, interpretation and attribution contribute substantially to the persistence of typically somatoform symptoms and IEI complaints. Treatment of IEI and SFD should address these psychological factors and mechanisms.

ABSTRACT

OBJECTIVE: Idiopathic environmental intolerance (IEI), also known as multiple chemical sensitivity, is a chronic, polysymptomatic condition that cannot be explained by an organic disease. Physical and psychological complaints are believed to be sustained by low levels of chemically unrelated substances in the environment. At present, it is unclear whether IEI is an environmental illness or a variant of somatoform disorders (SFD). This study examined whether IEI can be distinguished from SFD with respect to self-reported symptoms, trait anxiety, body-related cognitions, and symptom attributions. METHODS: We compared 54 subjects with IEI, 54 subjects with SFD but without IEI, and 44 subjects with neither IEI nor SFD on symptom scales, psychological questionnaires, and structured interviews for IEI, depression, anxiety, and SFD. RESULTS: More than half of the IEI subjects met Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria of SFD. This group shared both symptoms and psychological features of somatization with the SFD group. IEI subjects who did not fulfill criteria for a specific SFD were less impaired by their chemical sensitivity but differed nevertheless from nonsomatoform controls by significantly higher symptom scores, higher trait anxiety, a focus on autonomic sensations, and more pronounced somatic symptom attributions. These psychological features were significantly associated with the burden of somatic symptoms in both SFD and IEI. Furthermore, self-reported allergy but not total immunoglobulin E correlated with symptom burden in the total sample. CONCLUSIONS: The similarity of IEI and SFD regarding symptoms and psychological features of somatization support the hypothesis that IEI is a variant of SFD.

ABSTRACT

BACKGROUND: EACC is a disease of the external auditory canal resulting in destruction of adjacent tissue. However, the role of the surrounding mesenchymal fibroblasts of the perimatrix still remains unclear. In this study we treat isolated fibroblasts of EACC with VEGF and determine FGF-2 levels. We also treat the fibroblast cultures with FGF-2 and measured VEGF levels. METHODS: All EACC cell cultures were obtained from five patients undergoing surgery and used at passage 3. After 1-4 days incubation with 50 ng/mL FGF-2, and 1-8 days incubation with 50 pg/mL VEGF incubation, the expression of the FGF-2 and VEGF protein in the supernatants of the HGF/SF-treated and -untreated culture cell lines was analyzed, respectively. RESULTS: After 8 days of incubation with 50 ng/mL VEGF, the levels of FGF-2 decreased. However, after 4 days of incubation with FGF-2 the VEGF levels increased significantly in treated tissue culture (p <0.05) in comparison to untreated EACC fibroblasts. The total protein concentration showed no significant difference in both cultures (p >0.05). CONCLUSIONS: In summary, exogenous FGF-2 increased fibroblast expression of VEGF, which is a major autocrine mediator of FGF-2-induced angiogenesis and proliferation. However, incubation with VEGF resulted in decrease of FGF-2 levels. Regarding the slow growth of the fibroblasts, they may not be as likely to exhibit a reactive or invasive phenotype as seen in middle ear cholesteatoma fibroblasts.
