Assessing health-related quality of life using the Wound-QoL-17 and the Wound-QoL-14-Results of the cross-sectional European HAQOL study using item response theory.

For assessing health-related quality of life in patients with chronic wounds, the Wound-QoL questionnaire has been developed. Two different versions exist: the Wound-QoL-17 and the Wound-QoL-14. For international and cross-cultural comparisons, it is necessary to demonstrate psychometric properties in an international study.

Validation of the Wound-QoL-17 and the Wound-QoL-14 in a European sample of 305 patients with chronic wounds.

The Wound-QoL assesses the impact of chronic wounds on patients' health-related quality of life (HRQoL). A 17-item and a shortened 14-item version are available. The Wound-QoL-17 has been validated for multiple languages.

How does a chronic wound change a patient's social life? A European survey on social support and social participation.

Chronic wounds can severely limit patient's social life. This cross-sectional study investigated quantitatively social support of patients with chronic wounds, its association with health-related quality of life as well as qualitatively changes in social participation of these patients. Overall, 263 patients from seven countries participated.

Results of a 10-year web-based health promotion campaign against skin cancer in Switzerland.

Skin cancer is the most common malignancy with rising incidence. Although early detection can be lifesaving, prevention programmes are under-utilized. In 2008, a group of board-certified dermatologists in Switzerland established a website aimed at educating about skin cancer risk factors and providing guidance on self-assessment.

Frequency, Treatment and Outcome of Immune-Related Toxicities in Patients with Immune-Checkpoint Inhibitors for Advanced Melanoma: Results from an Institutional Database Analysis.

Immune checkpoint inhibitors (ICIs) can induce immune-related adverse events (irAEs), which may result in treatment discontinuation. We sought to describe the onset, frequency, and kinetics of irAEs in melanoma patients in a real-life setting and to further investigate the prognostic role of irAEs in treatment outcomes. In this retrospective single-center cohort study, we included 249 melanoma patients.

Ectopic axillary breast cancer in a male patient.

Ectopic breast tissue can persist in the axilla due to lack of involution of mammary glands along the mammary lines. It is rare in men, and the malignant transformation to breast cancer has occasionally been described. Differential diagnosis of any axillary tumor should include breast cancer arising at ectopic sites.

Retrospective Analysis of Treatment and Complications of Immune Checkpoint Inhibitor-Associated Colitis: Histological Ulcerations as Potential Predictor for a Steroid-Refractory Disease Course.

Background/aims: Among the severe immune-related adverse events (irAEs) that occur with immune checkpoint inhibitor (ICI) therapy, colitis is the most frequent one. This study aimed at describing the experience from the largest gastroenterology unit in Switzerland with immune checkpoint inhibitor-associated colitis (ICIAC), its clinical presentation, management, and outcomes.

Methods: We performed a retrospective review of patients who were referred for the evaluation of ICIAC between January 2011 and October 2018 to the Division of Gastroenterology and Hepatology, University Hospital Zurich.

How I treat metastatic melanoma.

Tremendous progress in basic and clinical research has completely revolutionised the management of advanced melanoma, and this dramatic development is still ongoing. In this environment, state-of-the-art patient care is a major challenge. We describe how patient-centred medicine is organised in a leading referral centre that is also involved in early and late clinical trials and is part of a worldwide network for translational research.

Single-center real-life experience with low-dose ipilimumab monotherapy in adjuvant setting for patients with stage III melanoma.

Ipilimumab is approved for adjuvant melanoma treatment at a dose of 10 mg/kg, but its use is limited owing to high toxicity and treatment-associated costs. We retrospectively analyzed 29 patients who underwent complete resection of stage IIC-III melanoma and were treated with ipilimumab 3 mg/kg in an adjuvant setting. The aim was to assess development of adverse events (primary endpoint) and to evaluate survival outcomes (secondary endpoint) under adjuvant treatment with ipilimumab in a real-life setting.

Keratinocytic Malfunction as a Trigger for the Development of Solar Lentigines.

Introduction: Solar lentigines (SL) affect chronically UV-radiated skin. Treatment is often refractory. Deeper knowledge on its pathogenesis might improve therapeutic effects.

The World of Melanoma: Epidemiologic, Genetic, and Anatomic Differences of Melanoma Across the Globe.

Purpose Of Review: As cancer remains an increasing problem in industrial countries, the incidence of melanoma has risen rapidly in many populations during the last decades and still continues to rise. Current strategies aiming to control the disease have largely focused on improving the understanding of the interplay of causal factors for this cancer.

Recent Findings: Cutaneous melanoma shows clear differences in incidence, mortality, genomic profile, and anatomic presentation, depending on the country of residence, ethnicity, and socioeconomic status.

Short- and long-term effects of two emollients on itching and skin restoration in xerotic eczema.

Pruritus is associated with various skin diseases, dry skin, and with it an impaired skin barrier function. The study objective was to investigate short-term and long-term effects of two emollients on symptoms and skin barrier functions in xerotic eczema. Randomized, double-blind, study enrolling females/males, with bilateral itching.

Sarcoid-like reactions in patients receiving modern melanoma treatment.

The development of cancer immunotherapy and targeted therapy has reached an important inflection point in the history of melanoma. Immune checkpoint inhibitors and kinase inhibitors are today's standard of care treatments in advanced melanoma patients. Treatment-related toxicities can be very intriguing and quite challenging.

A Prospective Trial Comparing Q-Switched Ruby Laser and a Triple Combination Skin-Lightening Cream in the Treatment of Solar Lentigines.

Background: Quality-switched (QS) laser therapy is a safe and well-established treatment option for removing solar lentigines. Triple combination therapy (TCT) with the active pharmaceutical ingredients hydroquinone 5%, tretinoin 0.03%, and dexamethasone 0.

Topical Timolol for Infantile Hemangiomas: Evidence for Efficacy and Degree of Systemic Absorption.

Background: Topical use of timolol for infantile hemangiomas has recently emerged with promising results. It is unknown whether topical β-blockers act locally or if their effect is partly due to systemic absorption. This study investigates whether topically applied timolol is absorbed and reports on the efficacy of this treatment.

profiling reveals immunomodulatory effects of sorafenib and dacarbazine on melanoma.

Sorafenib is a multi-kinase inhibitor used alone or in combination with dacarbazine to treat metastasized melanoma. Our study investigated the relationship between metabolic response assessed by PET-CT and global transcriptome changes during sorafenib and dacarbazine therapy in patients with advanced melanoma. We conducted an open-label, investigator-initiated study that enrolled 13 sorafenib-naïve Stage IV melanoma patients, whose metastases were accessible for repeated biopsies.

Coexpression of SOX10/CD271 (p75(NTR)) and β-Galactosidase in Large to Giant Congenital Melanocytic Nevi of Pediatric Patients.

Background: Congenital melanocytic nevi (CMNs) are melanocytic neoplasms that can transform into melanoma. However, this development is impeded in the majority of cases and mostly affects patients with large or giant CMNs.

Methods: To elucidate mechanisms that keep CMNs from malignant transformation, CMN tissue biopsies were investigated for p-ERK and senescence markers by immunohistochemistry and for SOX10/CD271 (p75(NTR)) by immunofluorescence.

Management of split-thickness skin graft donor sites: a randomized controlled trial of calcium alginate versus polyurethane film dressing.

Background: Split-thickness skin graft (STSG) donor sites sometimes cause more postoperative morbidity for patients than the wound covered with the graft. Yet, there is no consensus on which dressings are best suited to treat these donor sites.

Objective: To evaluate two commonly used modern wound dressings in the postoperative healing of STSG donor sites in a prospective randomized controlled trial.

Phototherapy with UVB narrowband, UVA/UVBnb, and UVA1 differentially impacts serum 25-hydroxyvitamin-D3.

Background: Ultraviolet (UV) B radiation increases serum 25-hydroxyvitamin-D3 [25(OH)D], but the influence of UVA1 and UVA/narrowband UVB (UVBnb) phototherapy on serum vitamin D is unknown.

Objective: We sought to investigate the influence of UVBnb, UVA1, and UVA/UVBnb phototherapy on serum levels of 25(OH)D and related parameters in patients with an inflammatory skin condition.

Methods: 25(OH)D, as well as calcium, parathormone, phosphate, and albumin were measured before therapy, 2 weeks after start, and after completion of the phototherapy.

Basal cell carcinoma: a paradigm for targeted therapies.

Introduction: Basal cell carcinoma (BCC) is the most frequent cancer with increasing incidence over the last decades. Standard of care is surgical excision, upon which complete tumour clearance is achieved in most cases. However, a small subgroup of patients will have remnants of disease post-excision and require further treatment options.

Dermatofibrosarcoma protuberans in childhood treated with slow Mohs micrographic surgery.

Dermatofibrosarcoma protuberans (DFSP) in childhood is a rare tumor with high recurrence rates. Wide local excision can result in disfiguring mutilation, whereas Mohs micrographic surgery (MMS) reduces surgical margins. MMS in children is not performed routinely, as the required infrastructures such as a histopathology lab in close proximity to the operating room is often lacking.

Long-term recurrence rate of large and difficult to treat cutaneous squamous cell carcinomas after superficial radiotherapy.

Background: Surgical excision is the gold standard for cutaneous squamous cell carcinoma (cSCC), however its application is limited in specific cases. Superficial radiotherapy (RTx) is an alternative treatment option, but long-term follow-up data are limited.

Objective: To determine the outcome of superficial RTx of cSCC in correlation to histological differentiation grade and tumor localization.

Intense pulsed light.

In addition to lasers, intense pulsed light (IPL) sources are widely used in medicine to treat various indications, such as vascular lesions, irregular pigmentation and hypertrichosis. In contrast to lasers, IPL systems are broadband flash lamps that emit polychromatic incoherent light ranging from visible to infrared (500-1,300 nm). Optical filters are used to tailor the polychromatic light to specific needs.

Different patterns of fibronectin and tenascin-C splice variants expression in primary and metastatic melanoma lesions.

We have investigated the staining patterns of primary and metastatic melanoma lesions using F8, L19 and F16. These three clinical-stage antibodies are currently being studied in clinical trials for the pharmacodelivery of cytokines or therapeutic radionuclides to neoplastic sites in patients with cancer. Frozen sections of 24 primary and 29 metastatic melanoma lesions were stained, using immunofluorescence procedures, with biotinylated preparations of the F8, L19 and F16 antibodies, which are specific to the alternatively spliced extra domain A and extra domain B domains of fibronectin and A1 domain of tenascin-C, respectively.
