Autologous hematopoietic stem cell transplantation improves long-term survival-data from a national registry.

Background: Current recommendations on the management of systemic sclerosis (SSc) suggest that autologous hematopoietic stem cell therapy (HSCT) can be a rescue therapy for patients with rapidly progressive SSc.

Objectives: To assess the safety and efficacy of HSCT for patients with SSc and to compare these with non-HSCT patients in a control cohort with adjusted risk factors.

Methods: A retrospective analysis of data from the multicentric German network for systemic scleroderma (DNSS) with 5000 patients with SSc.

Computer-aided clinical image analysis as a predictor of sentinel lymph node positivity in cutaneous melanoma.

Background: Delays in sentinel lymph node (SLN) biopsy may affect the positivity of non-SLNs. For these reasons, effort is being directed at obtaining reliable information regarding SLN positivity prior to surgical excision. However, the existing tools, , dermoscopy, do not recognize statistically significant predictive criteria for SLN positivity in melanomas.

Development and Validation of Dietary Behavior Inventory-Surgery (DBI-S) in the Scope of International Post-Bariatric Surgery Guidelines and Recommendations.

(1) Dietary behavior is highly relevant for patients after bariatric surgery. No instrument exists assessing adherence to medical guidelines concerning the dietary behavior of patients after bariatric surgery. The aim of this study was to develop and validate such an instrument.

Awareness of Human Papillomavirus (HPV) and HPV Vaccination amongst the General Population in Germany: Lack of Awareness and Need for Action.

Introduction: The oncogenic human papillomaviruses (HPV) types 16 and 18 contribute to more than 73% cases of all HPV-related cancers and commonly affect the anogenital and head and neck region, with rapidly rising incidence rates of HPV-related oropharyngeal squamous cell carcinomas (OPSCC). HPV vaccination has the potential to decrease the burden of HPV-related disease, but vaccination rates remain low in many countries. We investigated the level of awareness of HPV, and HPV-OPSCC in particular, in a representative sample of the German population.

S1 Guidelines for the Kaposi Sarcoma.

Kaposi's sarcoma (KS) is a rare, malignant, multilocular vascular disease originating from lymphatic endothelial cells that can primarily affect the skin and mucous membranes, but also the lymphatic system and internal organs such as the gastrointestinal tract, lungs or liver. Five epidemiological subtypes of KS with variable clinical course and prognosis are distinguished, with increased incidence in specific populations: (1) Classical KS, (2) Iatrogenic KS in immunosuppression, (3) Endemic (African) lymphadenopathic KS, (4) Epidemic, HIV-associated KS and KS associated with immune reconstitution inflammatory syndrome (IRIS), and (5) KS in men who have sex with men (MSM) without HIV infection. This interdisciplinary guideline summarizes current practice-relevant recommendations on diangostics and therapy of the different forms of KS.

Real-World Therapy with Pembrolizumab: Outcomes and Surrogate Endpoints for Predicting Survival in Advanced Melanoma Patients in Germany.

Knowledge on the real-world characteristics and outcomes of pembrolizumab-treated advanced melanoma patients in Germany and on the value of different real-world endpoints as surrogates for overall survival (OS) is limited. A sample of 664 pembrolizumab-treated patients with advanced melanoma from the German registry ADOReg was used. We examined OS, real-world progression-free survival (rwPFS), real-world time to next treatment (rwTtNT), and real-world time on treatment (rwToT).

Persistent lipedema pain in patients after bariatric surgery: a case series of 13 patients.

Background: Lipedema often remains undiagnosed in patients with obesity, leading to mismanagement of treatment. Because of this, despite remarkable weight loss after bariatric surgery and decreases in hip and abdomen circumference, some patients show only small decreases in circumference of the extremities and report persistent limb pain.

Objective: The goal of this work is to raise awareness of lipedema coincident with obesity, mistakenly diagnosed as obesity alone, in order to ensure the correct diagnosis of the condition and to achieve better treatment outcomes for people with lipedema and coincident obesity.

Redefining WILD syndrome: a primary lymphatic dysplasia with congenital multisegmental lymphoedema, cutaneous lymphovascular malformation, CD4 lymphopaenia and warts.

Background: Primary lymphoedema (PL) syndromes are increasingly recognised as presentations of complex genetic disease, with at least 20 identified causative genes. Recognition of clinical patterns is key to diagnosis, research and therapeutics. The defining criteria for one such clinical syndrome, 'WILD syndrome' (arts, mmunodeficiency, ymphoedema and anogenital ysplasia), have previously depended on a single case report.

Natural History of Cutaneous Human Polyomavirus Infection in Healthy Individuals.

Several human polyomaviruses (HPyVs) were recently discovered. Merkel cell polyomavirus (MCPyV) induces Merkel cell carcinoma. HPyV6, HPyV7, and TSPyV have been associated with rare skin lesions in immunosuppressed patients.

Digital Quantification of Tumor PD-L1 Predicts Outcome of PD-1-Based Immune Checkpoint Therapy in Metastatic Melanoma.

Background: PD-1-based immune checkpoint blockade (ICB) is a highly effective therapy in metastatic melanoma. However, 40-60% of patients are primarily resistant, with valid predictive biomarkers currently missing. This study investigated the digitally quantified tumor PD-L1 expression for ICB therapy outcome prediction.

Characterisation of anal intraepithelial neoplasia and anal cancer in HIV-positive men by immunohistochemical markers p16, Ki-67, HPV-E4 and DNA methylation markers.

Human papillomavirus (HPV)-induced anal intraepithelial neoplasia (AIN, graded 1-3) is highly prevalent in HIV-positive (HIV+) men who have sex with men (MSM), but only a minority of lesions progresses to cancer. Our study aimed to characterise comprehensively anal tissue samples from a cross-sectional series (n = 104) of HIV+ MSM and longitudinal series (n = 40) of AIN2/3 progressing to cancer using different biomarkers. The cross-sectional series consisted of 8 normal, 26 AIN1, 45 AIN2, 15 AIN3 and 10 anal squamous cell carcinoma.

Induction and exacerbation of subacute cutaneous lupus erythematosus following mRNA-based or adenoviral vector-based SARS-CoV-2 vaccination.

Evidence is accumulating that COVID-19 vaccines might induce or exacerbate autoimmune rheumatic diseases. The currently available COVID-19 vaccines include mRNA and recombinant adenoviral vector vaccines, both encoding SARS-CoV-2 spike protein production as the primary target for neutralizing antibodies. We report a case of subacute cutaneous lupus erythematosus (SCLE) following mRNA vaccination with the Pfizer mRNA vaccine BNT162b2, and summarize the current literature on CLE occurring after COVID-19 vaccination.
