Rosacea is strongly associated with melanoma in Caucasians.

Rosacea is often considered a cosmetic problem but is known to be associated with a variety of comorbidities. To identify such risks, we generated two age- and sex-matched real-world cohorts of 122,444 patients each with and without rosacea. In contrast to earlier studies, we found significant associations with malignant melanoma (OR 6.

Blood T Helper Memory Cells: A Tool for Studying Skin Inflammation in HS?

Hidradenitis suppurativa (HS) is an inflammatory skin disease characterized by painful lesions on intertriginous body areas such as the axillary, inguinal, and perianal sites. Given the limited treatment options for HS, expanding our knowledge of its pathogenetic mechanisms is a prerequisite for novel therapeutic developments. T cells are assumed to play a crucial role in HS pathogenesis.

S2k Guideline - Merkel cell carcinoma (MCC, neuroendocrine carcinoma of the skin) - Update 2022.

Merkel cell carcinoma (MCC, ICD-O M8247/3) is a rare, malignant, primary skin tumor with epithelial and neuroendocrine differentiation. The tumor cells share many morphologic, immunohistochemical, and ultrastructural features with cutaneous Merkel cells. Nevertheless, the cell of origin of MCC is unclear.

The impact of surgical interventions on the psychosocial well-being of patients with hidradenitis suppurativa.

Background And Objectives: Hidradenitis suppurativa is a chronic inflammatory skin disease. Depending on disease severity, a combination of conservative and surgical treatments is necessary. This analysis aimed to determine the impact of surgical interventions on patient psychosocial well-being.

The impact of hidradenitis suppurativa on professional life.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory disease that affects intertriginous skin.

Objectives: To determine the extent of work ability and productivity impairment as a result of HS in Germany.

Methods: A prospective, multicentre, epidemiological, noninterventional study of patients with HS was conducted.

Sex-disaggregated population analysis in patients with hidradenitis suppurativa.

Background: Hidradenitis suppurativa (HS) is a common chronic inflammatory skin disease, which affects both sexes.

Objectives: Identification of sex-specific risk factors, comorbidity, clinical manifestations, and treatments in HS patients.

Methods: A non-interventional, cross-sectional, mono-centric study with 500 HS patients.

Patient Preferences in Hidradenitis Suppurativa (APProach-HS): a discrete choice experiment.

Background And Objectives: Treatment options for moderate-to-severe hidradenitis suppurativa (HS) comprise antibiotics, biologics, and different surgical methods. These approaches differ substantially regarding the treatment process, success rates, and adverse events. However, information on patient preferences for HS therapies is hitherto scarce.

[Hidradenitis suppurativa /acne inversa-surgical options, reconstruction and combinations with drug therapies-an update].

Hidradenitis suppurativa/acne inversa (HS/AI) is a chronic inflammatory skin disease whose treatment includes both conservative and surgical treatment options. In Hurley stages II and III, surgical resection of irreversibly destroyed tissue should be the objective. For this purpose several resection techniques exist, which differ primarily with regard to their invasiveness and tendency to recur.

Features Associated With Quality of Life Impairment in Hidradenitis Suppurativa Patients.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with an adverse impact on patients' quality of life (QoL). To quantify QoL impairment in patients in Germany suffering from HS and to identify the parameters associated with QoL impairment. A non-interventional, cross-sectional, mono-centric study with 500 HS patients.

Delayed Diagnosis of Hidradenitis Suppurativa and Its Effect on Patients and Healthcare System.

Background: Hidradenitis suppurativa (HS) is a neglected chronic inflammatory disease with long delay in diagnosis. Besides pain, purulent discharge, and destruction of skin architecture, HS patients experience metabolic, musculoskeletal, and psychological disorders.

Objectives: To determine the delay in HS diagnosis and its consequences for patients and the healthcare system.

S2k guidelines for Merkel cell carcinoma (MCC, neuroendocrine carcinoma of the skin) - update 2018.

Merkel cell carcinoma (MCC, ICD-O M8247 / 3) is a rare malignant primary skin tumor with epithelial and neuroendocrine differentiation. The neoplastic cells share many morphological, immunohistochemical and ultrastructural characteristics with Merkel cells of the skin. The diagnosis of MCC is rarely made on clinical grounds.

The IL-1 Pathway Is Hyperactive in Hidradenitis Suppurativa and Contributes to Skin Infiltration and Destruction.

Hidradenitis suppurativa (HS) (also designated acne inversa) is a chronic inflammatory disease characterized by painful purulent skin lesions and progressive destruction of skin architecture. Despite the high burden for the patients, pathogenetic pathways underlying HS alterations remain obscure. When we examined the HS cytokine pattern, IL-1β turned out to be a highly prominent cytokine, overexpressed even compared with psoriatic lesions.

Current and future treatment of hidradenitis suppurativa.

This scholarly review on the current and future treatment of hidradenitis suppurativa (HS) focuses on medical and surgical treatment options, while novel pipeline drugs are also discussed. Treatment goals are to limit the incidence and duration of flares, reducing inflammation and suppuration, achieving local cure after surgery and, most importantly, to improve the quality of life of patients with HS. The type of medication and/or surgery should be chosen based on the stage of the disease and the degree of inflammation.

Association of Hidradenitis Suppurativa With Body Image.

Importance: Hidradenitis suppurativa (HS) leads to disfigurement and painful eruptions in terminal hair follicles of the intertriginous skin, mainly of axillary, genitofemoral, and perianal sites. It is associated with an excessive impairment of quality of life, psychiatric disorders, and sexual distress. Body image impairment has been linked to depression and anxiety and has been described for some dermatologic disorders but has not yet been investigated in patients with HS.

Pyoderma outbreak among kindergarten families: Association with a Panton-Valentine leukocidin (PVL)-producing S. aureus strain.

Objectives: We report on an outbreak of skin and soft tissue infections (SSTI) among kindergarten families. We analyzed the transmission route and aimed to control the outbreak.

Methods: The transmission route was investigated by nasal screening for Panton-Valentine leukocidin (PVL)-producing Staphylococcus aureus (PVL-SA), subsequent microbiological investigation including whole genome sequencing and a questionnaire-based analysis of epidemiological information.
