The abrupt onset of the situation after a traumatic amputation and the preparatory discussions following unsuccessful attempts to preserve limbs with necessary amputation require a high level of empathy, attention and well-founded information individually tailored to the affected individuals. Optimization of the treatment process can only be achieved by considering these aspects.The self-motivation and cooperation of the patient should be encouraged. To achieve this goal, the professions involved are less suitable for counseling due to a lack of personal experience, whereas so-called peers, as knowledgeable and experienced advisors, are more appropriate. This insight can be derived from existing studies. Peer counseling has increasingly been integrated into routine treatment following amputations in trauma surgery, with positive effects. It is considered guideline-compliant therapy not only in rehabilitation. Against the background of long-standing legislation, especially the UN Convention on the Rights of Persons with Disabilities and the demands of those affected by amputation, the following presentation focuses on the instrumentalization and benefits of counseling. The structures of this particular counseling option, including regular training of counselors and established implementation, are currently not necessarily given but are continuously expanding and being adapted to needs. Concrete scientific evidence regarding measurable effects and positive impacts on outcomes is pending and are presented in a current research project., (© 2024.

Background: Studies have shown that Omicron breakthrough infections can occur at higher SARS-CoV-2 antibody levels compared to previous variants. Estimating the magnitude of immunological protection induced from COVID-19 vaccination and previous infection remains important due to varying local pandemic dynamics and types of vaccination programmes, particularly among at-risk populations such as health care workers (HCWs). We analysed a follow-up SARS-CoV-2 serological survey of HCWs at a tertiary COVID-19 referral hospital in Germany following the onset of the Omicron variant., Methods: The serological survey was conducted in January 2022, one year after previous surveys in 2020 and the availability of COVID-19 boosters including BNT162b2, ChAdOx1-S, and mRNA-1273. HCWs voluntarily provided blood for serology and completed a comprehensive questionnaire. SARS-CoV-2 serological analyses were performed using an Immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA). Antibody levels were reported according to HCW demographic and occupational characteristics, COVID-19 vaccination and SARS-CoV-2 infection history, and multivariate linear regression was used to evaluate these associations., Results: In January 2022 (following the fourth COVID-19 wave in Germany including the onset of the Omicron variant), 1482/1517 (97.7%) HCWs tested SARS-CoV-2 seropositive, compared to 4.6% in December 2020 (second COVID-19 wave). Approximately 80% had received three COVID-19 vaccine doses and 15% reported a previous laboratory-confirmed SARS-CoV-2 infection. SARS-CoV-2 IgG geometric mean titres ranged from 335 (95% Confidence Intervals [CI]: 258-434) among those vaccinated twice and without previous infection to 2204 (95% CI: 1919-2531) among those vaccinated three times and with previous infection. Heterologous COVID-19 vaccination combinations including a mRNA-1273 booster were significantly associated with the highest IgG antibody levels compared to other schemes. There was an 8-to 10-fold increase in IgG antibody levels among 31 HCWs who reported a SARS-CoV-2 infection in May 2020 to January 2022 after COVID-19 booster vaccination., Conclusions: Our findings demonstrate the importance of ongoing COVID-19 booster vaccination strategies in the context of variants such as Omicron and despite hybrid immunity from previous SARS-CoV-2 infections, particularly for at-risk populations such as HCWs. Where feasible, effective types of booster vaccination, such as mRNA vaccines, and the appropriate timing of administration should be carefully considered., (© 2024. The Author(s).)

Background: The long-term effects of mild Traumatic Brain Injury (TBI) in children and adolescents are increasingly discussed due to their potential impact on psycho-social development and education. This study aims to evaluate post-hospital care of children and adolescents after mild TBI using a physician survey., Methods: A self-developed, pre-tested questionnaire on diagnostics and treatment of TBI in outpatient care was sent to a representative sample of general practitioners and pediatricians in Germany., Results: Datasets from 699 general practitioners, 334 pediatricians and 24 neuropediatricians were available and included in the analysis. Nearly half of the general practitioners and most pediatricians say they treat at least one acute pediatric TBI per year. However, a substantive proportion of general practitioners are not familiar with scales assessing TBI severity and have difficulties assessing the symptoms correctly. Pediatricians seem to have better knowledge than general practitioners when it comes to treatment and outpatient care of TBI., Conclusions: To increase knowledge about TBI in outpatient physicians, targeted training courses should be offered, especially for general practitioners. Moreover, handing out written information about long-term effects and reintegration after TBI should be encouraged in outpatient practice.

Background: Chronic subdural hematoma (cSDH) is the most common complication of mild traumatic brain injury demanding neurosurgery in high-income countries. If undetected and untreated, cSDH may increase intracranial pressure and cause neurological deficiencies. The first-line intervention of choice is burr hole trepanation and hematoma evacuation. However, any third patient may experience rebleeding, demanding craniotomy with excess morbidity. Adjunct endovascular embolization of the frontal and parietal branches of the middle meningeal artery (MMA) is a promising approach to avoid relapse and revision but was hitherto not studied in a randomized trial., Methods: MEMBRANE is an investigator-initiated, single-center, randomized controlled trial. Male, female, and diverse patients older than 18 years scheduled for surgical evacuation of a first cSDH will be assigned in a 1:1 fashion by block randomization to the intervention (surgery plus endovascular MMA embolization) or the control group (surgery alone). The primary trial endpoint is cSDH recurrence within 3 months of follow-up after surgery. Secondary endpoints comprise neurological deficits assessed by the modified Rankin Scale (mRS) and recurrence- or intervention-associated complications during 3 months of follow-up. Assuming a risk difference of 20% of rebleeding and surgical revision, a power of 80%, and a drop-out rate of 10%, 154 patients will be enrolled onto this trial, employing an adaptive O'Brien-Fleming approach with a planned interim analysis halfway., Discussion: The MEMBRANE trial will provide first clinical experimental evidence on the effectiveness of endovascular embolization of the MMA as an adjunct to surgery to reduce the risk of recurrence after the evacuation of cSDH., Trial Registration: German Clinical Trials Registry (Deutsches Register Klinischer Studien [DRKS]) DRKS00020465.

Background: SARS-CoV-2 cases in Germany increased in early March 2020. By April 2020, cases among health care workers (HCW) were detected across departments at a tertiary care hospital in Berlin, prompting a longitudinal investigation to assess HCW SARS-CoV-2 serostatus with an improved testing strategy and associated risk factors., Methods: In May/June and December 2020, HCWs voluntarily provided blood for serology and nasopharyngeal/oropharyngeal (NP/OP) samples for real-time polymerase chain reaction (PCR) and completed a questionnaire. A four-tiered SARS-CoV-2 serological testing strategy including two different enzyme-linked immunosorbent assays (ELISA) and biological neutralization test (NT) was used. ELISA-NT correlation was assessed using Pearson's correlation coefficient. Sociodemographic and occupational factors associated with seropositivity were assessed with multivariate logistic regression., Results: In May/June, 18/1477 (1.2%) HCWs were SARS-CoV-2 seropositive, followed by 56/1223 (4.6%) in December. Among those tested in both, all seropositive in May/June remained seropositive by ELISA and positive by NT after 6 months. ELISA ratios correlated well with NT titres in May/June (R = 0.79) but less so in December (R = 0.41). Those seropositive reporting a past SARS-CoV-2 positive PCR result increased from 44.4% in May/June to 85.7% in December. HCWs with higher occupational risk (based on profession and working site), nurses, males, and those self-reporting COVID-19-like symptoms had significantly higher odds of seropositivity., Conclusions: This investigation provides insight into the burden of HCW infection in this local outbreak context and the antibody dynamics over time with an improved robust testing strategy. It also highlights the continued need for effective infection control measures particularly among HCWs with higher occupational risk., (© 2022. The Author(s).)

Carotenoids, naturally occurring lipophilic micronutrients, possess an antioxidant activity associated with protection from damage induced by free radicals. The present study investigated an innovative non-invasive method to measure cutaneous levels of lycopene and beta-carotene and to monitor the distribution of orally administered lactolycopene in human skin and plasma. A double-blind placebo-controlled randomized study was performed in 25 volunteers, who were under a lycopene-deprived diet (4 weeks prior to study until end of the study) and orally received either lactolycopene or placebo for 12 weeks. Skin and plasma levels of lycopene and beta-carotene were monitored monthly using Raman spectroscopy and HPLC, respectively. Cutaneous levels of lycopene and beta-carotene monitored by resonance Raman spectroscopy showed high reliability. Irrespective of the investigated area, cutaneous levels were sensitive to lycopene deprivation and to oral supplementation; the forehead showed the closest correlation to lycopene variation in plasma. Plasma and skin levels of lycopene were both sensitive to oral intake of lactolycopene and, interestingly, also skin levels of beta-carotene. Thus, oral supplementation with lycopene led to an enrichment of beta-carotene in human skin, possibly due to the fact that carotenoids act in the skin as protection chains, with a natural protection against free radicals.

Normolipemic plane xanthoma normally occurs in adults. We report the atypical instance of a 9-year-old boy who developed disseminated, flat, yellow-brown plaques up to 2 to 3 cm without any complaints. The histology showed the hallmarks of xanthoma, including the presence of CD68+ foam cells and Touton giant cells. No systemic involvement or lipid disorders were evident. It is important to perform regular follow-up of these patients because normolipemic plane xanthoma often precedes myeloproliferative disorders such as leukemia, paraproteinemia, or lymphoma.

Up to 30% of all psoriatic patients show their first symptoms during childhood and adolescence. In 1/4 of these children, psoriatic lesions appear within the first two years of life. The treatment of pediatric psoriasis differs considerably in several ways from that of adults. Not only the age and intensity but also physical development, prognostic criteria and social background should be considered. Standard procedures, clinical trials of high quality and therapeutic guidelines for psoriasis in childhood are still lacking. This review surveys the therapeutic management of pediatric and juvenile psoriasis. Current topical and systemic therapy options are critically reviewed. Prevention as well as enhancement of quality of life are also considered.

Epidermolysis bullosa (EB), a hereditary, blistering form of dermatosis, can be divided into the following three main groups: epidermolysis bullosa simplex (EBS), junctional epidermolysis bullosa (JEB) and dystrophic epidermolysis bullosa (DEB). The previously known form of generalized atrophic benign epidermolysis bullosa (GABEB) is classified as junctional epidermolysis bullosa non-Herlitz (JEB-nH) today. An 11-year-old boy with junctional epidermolysis bullosa non-Herlitz with urethal involvement had a complicated course with bladder obstruction and secondary renal insufficiency. According to currently available literature, this is the earliest case known of JEB-nH with involvement of the urinary tract in childhood. Taking into account the complicated course in this young patient, it must be emphasized that in cases of epidermolysis bullosa hereditaria, uncommon affections occurring in infancy should be given careful attention, as such types of associated manifestations are mainly responsible for the lethality in this disease.
