This study presents Cutibacterium acnes (formerly Propionibacterium acnes) subgroups distribution on the back and face of severe acne patients versus healthy controls. It notably shows a drastic reduction of the phylotype diversity on the back of acne group comparing with healthy controls. These data suggest the possibility to set up innovative acne therapies such as probiotic-based systems in order to restore the phylotype diversity associated with healthy skin.

Dead Sea climatotherapy (DSC) is a therapeutic modality for a variety of chronic skin conditions including psoriasis, vitiligo and atopic dermatitis. Previous studies have documented microbiome changes following therapeutic regimens for the aforementioned diseases. In the article entitled "Temporal Stability of the Healthy Human Skin Microbiome Following Dead Sea Climatotherapy," the authors describe changes to the healthy skin fungal and bacterial microbiome following Dead Sea climatotherapy. Their research sheds light on the temporal dynamics of the skin microbiome using this therapeutic regimen and is important in the understanding of its mechanisms.

Prurigo nodularis (PN) is a subtype of chronic prurigo presenting single to multiple symmetrically distributed, hyperkeratotic and intensively itching papules and nodules. PN evolves along with chronic pruritus in the context of diverse dermatological, systemic, neurological or psychiatric conditions. Permanent scratching is possibly a major trigger of PN, although its exact pathophysiology remain ...

Treatment of vitiligo is challenging and requires a multidisciplinary approach. Fractional carbon dioxide (CO2) laser as an add-on to conventional treatment has been reported to be effective, but there is no consensus on its use. A systematic review was performed by searching major databases for relevant publications to February 2017. Six studies with 85 participants were included. For those with ...

Aquagenic pruritus (AP) has a significant influence on quality of life (QoL) in patients with polycythaemia vera. This study analysed the impact of AP on patient well-being in 102 patients with polycythaemia vera. Intensity of pruritus was evaluated using a visual analogue scale (VAS), verbal rating scale (VRS) and a 4-item Itch Questionnaire. Psychosocial aspects of AP were assessed with the Hosp ...

A growing body of research has indicated that pruritus is an important feature of hidradenitis suppurativa (HS). This study evaluated pruritus and pain among 103 patients with HS. Pruritus and pain intensity were assessed with a visual analogue scale, numerical rating scale and 4-item Itch Questionnaire. Dermatology Life Quality Index (DLQI) was implemented to assess quality of life (QoL) issues. ...

Dermatitis herpetiformis (DH) is an extra-intestinal manifestation of coeliac disease. The highest currently reported prevalence of DH is in Finland, but knowledge of diagnostic delay is limited. This study investigated the duration of rash prior to diagnosis in 446 patients with DH, analysing the results in 3 periods of 15 years. The diagnosis was considered delayed when the duration of rash befo ...

Systemic antipsoriatic treatment options are increasing rapidly. The aim of this nationwide discrete choice experiment was to compare patients’ (n = 222) and physicians’ (n = 78) preferences for outcome and process attributes of systemic antipsoriatics using Relative Importance Scores (RIS). Both groups considered Psoriasis Area and Severity Index 90 (PASI 90) to be most important (RIS ...

Chronic graft versus host disease (cGVHD) is a complication of allogeneic haematopoietic stem cell transplantation (HSCT). The aim of this study was to clinically characterize childhood cutaneous cGVHD. A retrospective study of children treated with HSCT at 2 tertiary medical centres in Israel between 2011 and 2014 was performed. A total of 112 children were included. Cutaneous cGVHD developed in ...

Alopecia areata (AA) is an immune-mediated disease causing temporary or permanent hair loss. Up to 46% of patients with AA also have nail involvement. The aim of this study was to determine the presence, types, and clinical implications of nail changes in patients with AA. This questionnaire-based survey evaluated 256 patients with AA. General demographic variables, specific nail changes, nail-rel ...

Cutaneous melanoma is a major concern in terms of healthcare systems and economics. The aim of this study was to estimate the direct costs of melanoma by disease stage, phase of diagnosis, and treatment according to the pre-set clinical guidelines drafted by the AIOM (Italian Medical Oncological Association). Based on the AIOM guidelines for malignant cutaneous melanoma, a highly detailed decision ...

Chronic somatic conditions, such as psoriasis, arthritis psoriatica and rheumatoid arthritis, have a large impact on patients’ lives. Tailored therapist-guided internet-based cognitive-behavioural therapy (ICBT) has been shown to be effective in improving physical and psychological well-being in these patients. Two cases are presented here, in order to provide an in-depth illustration of the cou ...

Health-related quality of life (HRQoL) is important in the management of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Disease-specific questionnaires exist, but with important shortcomings. The aim of this study was to develop and validate a questionnaire suitable for use in all patients with BCC and those with SCC. In a 4-phase trajectory, a preliminary questionnaire was created ...

The Revised Illness Perception Questionnaire (IPQ-R) has been shown to assess illness perception reproducibly in primary cutaneous T-cell lymphomas (CTCL). Illness perception reflects patients' individual concepts of understanding and interpretation of the disease, influencing illness behaviour and health-related quality of life (HRQOL). This study investigated the clinical relevance of the relati ...

Current literature on risk factors for surgical site infection (SSI) in dermatological surgery in the absence of antibiotic prophylaxis is limited. The aim of this study was to retrospectively evaluate patients presenting for dermatological surgery. A total of 1,977 procedures were reviewed. SSI was clinically suspected in 79 (4.0%) patients and confirmed by culture in 38 (1.9%). Using the stricte ...

Patients with an inherited autosomal-dominant disorder, capillary malformation–arteriovenous malformation (CM-AVM), frequently have mutations in Ras P21 protein activator 1 (RASA1). The aims of this study were to determine the prevalence of germline RASA1 variants in a French multicentre national cohort of children, age range 2–12 years, with sporadic occurrence of capillary malformation (CM) ...

Dead Sea climatotherapy (DSC) is a therapeutic modality for a variety of chronic skin conditions, yet there has been scarce research on the relationship between the cutaneous microbiota and disease states in response to DSC. We characterized the skin bacterial and fungal microbiome of healthy volunteers who underwent DSC. Bacterial community diversity remained similar before and after treatment, w ...

Propionibacterium acnes, a major member of normal skin microbiota, is subdivided into 6 phylotypes: IA1, IA2, IB, IC, II and III. This study investigated P. acnes subgroups on the face and back in patients with severe acne and in healthy controls. In 71.4% of patients with severe acne, P. acnes phylotypes were identical on the face and back, whereas this was the case in only 45.5% of healthy contr ...

Placebo effects are positive outcomes that are not due to active treatment components, which may be elicited even when patients are aware of receiving an inert substance (open-label). This proof-of-principle study investigated for the first time whether open-label placebo effects on itch can be induced by verbal suggestions alone. Ninety-two healthy volunteers were randomized to experimental (open ...
