Source Clinical and experimental dermatology; Dec 2019 Psychodermatology remains a niche sub-specialty in the United Kingdom (UK), with very few dedicated services available for patients with such problems. Despite this, up to 85% of dermatology patients say that psychosocial aspects of their skin disease are a major component of their condition, indicating an enormous unmet need.s1 Our perception is that general dermatologists and psychiatrists may lack confidence in diagnosing and managing patients with psychodermatological problems, the vast majority of whom will not be cared for in a specialist service.Copyright © 2019 British Association of Dermatologists.

Objective(s): The aim of this study was to summarize the clinical and histopathologic features in a case series of poikilodermatous plaque-like hemangioma. Method(s): Sixteen cases were identified from the routine clinical and referral practices of the authors. Clinical characteristics, including demographic details and clinical morphology, were collated. The salient histopathologic features, including immunohistochemical staining results, were summarized. Result(s): The lesions were usually solitary erythematous-to-violaceous poikilodermatous plaques on the lower extremities and pelvic girdle, with an indolent clinical course. Mean age of affected patients was 72 (range 58-80) years, and there was a male predominance. Histology comprised a distinctive band-like proliferation of vascular channels suggestive of postcapillary venules within the superficial dermis with a background of fibrosis, edema, and loss of elastic fibers. Despite the clinical atrophic appearance, acanthosis was a frequent finding. Limitation(s): Retrospective study. Conclusion(s): Poikilodermatous plaque-like hemangioma is a distinctive and previously undescribed vascular proliferation defined by a constellation of consistent and reproducible clinical and histologic features.Copyright © 2019 American Academy of Dermatology, Inc.

The cause is unknown, but a number of potential aetiological factors have been identified. Aim(s): To examine a cohort of patients with prepubertal-onset vulval LS (VLS) and assess baseline characteristics, clinical presentation, potential precipitating and predisposing factors, and response to treatment. Method(s): Data were collected from case notes on patients aged < 18 years diagnosed with prepubertal-onset VLS attending a specialist vulval dermatology service. Data included clinical presentation, comorbidities, family history, therapy and response to treatment. Result(s): In total, 26 paediatric patients were identified. The median age at onset of symptoms was 5 years (range 2-8.5 years). Many previously identified potential aetiological factors for the development of VLS were identified, including family history, trauma, autoimmune disease and hormonal factors. A significant proportion of patients had a history of urinary tract symptoms, including incontinence and urinary tract infection. Most patients responded well to a standard course of induction topical therapy followed by maintenance therapy, but some, including three patients with ongoing urinary incontinence and three postpubertal patients, continued to have active disease. Conclusion(s): A detailed assessment is essential in patients with VLS so that potential predisposing factors and comorbidities can be identified and managed. Urinary incontinence may be implicated in the development of paediatric VLS and may prevent adequate disease control. Paediatric VLS can persist through puberty, thus long-term follow-up is advised.Copyright © 2019 British Association of Dermatologists Author(s): Petridis C.; Navarini A.A.; Dand N.; Saklatvala J.; Trembath R.C.; Simpson M.A.; Baudry D.; Duckworth M.; Allen M.H.; Pink A.E.; McGrath J.A.; Smith C.H.; Barker J.N.; Curtis C.J.; Lee S.H.; Burden A.D.; Layton A.; Bataille V.; Spector T.D.; Carlavan I.; Voegel J.J.; Alexandroff A.; Anstey A.; Azad J.; Aziz O.; Cutler T.; Hood S.; Rallan D.; Burrows N.; Butt A.; Cartwright P.; Chapman A.; Clayton T.H.; Cliff S.; Daly B.; Darvay A.; DeGiovanni C.; Downs A.; Dwyer C.; English J.; Ferguson A.; Fleming C.; Fraser-Andrews E.; Goodfield M.; Grattan C.E.; Hempel H.; Hughes B.; Ladoyanni E.; Lyon C.; Mahmud A.; Malik M.; Mallon E.; Meggitt S.; Messenger A.; Moosa Y.; Munn S.; Ormerod A.; Ross J.; Salvary I.; Wachsmuth R.; Wahie S.; Walton S.; Walsh S.; Williamson D.; Willis C.
Source: Nature Communications; Dec 2018; vol. 9 (no. 1) Publication Date: Dec 2018 Publication Type(s): Article PubMedID: 30542056 Available at Nature Communications - from Europe PubMed Central - Open Access Abstract:Acne vulgaris is a highly heritable common, chronic inflammatory disease of the skin for which five genetic risk loci have so far been identified. Here, we perform a genome-wide association study of 3823 cases and 16,144 controls followed by meta-analysis with summary statistics from a previous study, with a total sample size of 26,722. We identify 20 independent association signals at 15 risk loci, 12 of which have not been previously implicated in the disease. Likely causal variants disrupt the coding region of WNT10A and a P63 transcription factor binding site in SEMA4B. Risk alleles at the 1q25 locus are associated with increased expression of LAMC2, in which biallelic loss-of-function mutations cause the blistering skin disease epidermolysis bullosa. These findings indicate that variation affecting the structure and maintenance of the skin, in particular the pilosebaceous unit, is a critical aspect of the genetic predisposition to severe acne.Copyright © 2018, The Author(s).
