Acne Vulgaris in Skin of Color: A Systematic Review of the Effectiveness and Tolerability of Current Treatments.

Acne vulgaris is a common dermatosis frequently encountered in general dermatology and presents significant health-related quality of life and psychological challenges. Clinical studies on acne vulgaris in skin of color are limited; thus, it is likely that treatment recommendations to patients with darker skin types are drawn from trial data based on Caucasian skin. The aim of this study was to systematically review the effectiveness and tolerability of treatments used to treat acne vulgaris in patients with skin of color. A literature search was performed in the PubMed, Embase, and Scopus bibliographic databases, with a total of 1,477 retrieved articles, of which 1,316 were excluded after initial screening. Of the 93 studies assessed, 55 studies met our inclusion criteria (28 randomized controlled trials, 4 cohort studies, 6 post-hoc analyses, and 12 other interventional trials). The studies reported a total of 21,202 patients. Most studies explored topical therapies (23 studies) and photodynamic therapy (13 studies). Other treatments included laser/light therapy, systemic therapy, chemical peels, and radiofrequency and microneedling. In general, the different treatment modalities offered an improvement in lesion count and were well tolerated, with no report of major adverse events. However, due to limited evidence, we were unable to draw firm conclusions from the results of this review to guide decisions in practice, particularly with respect to long-term outcomes, in patients with skin of color and acne vulgaris.

Physical and psychological impacts of handwashing and personal protective equipment usage in the COVID-19 pandemic: A UK based cross-sectional analysis of healthcare workers.

The COVID-19 pandemic has necessitated intensified handwashing and mask usage for healthcare staff. A retrospective cross-sectional study was performed primarily to investigate the potential skin damage and secondary impacts on wellbeing of staff resulting from these practices. Additionally the availability and uptake of occupational health services and moisturisers in the work place was also assessed. The survey was distributed to NHS staff between April and May 2020 and asked questions regarding skin damage, impact on wellbeing and availability and utilisation of occupational health input and moisturisers. Of the 211 responders, 167 washed their hands more than ten times per shift. Three quarters of these reported cracks or fissures in one or more regions of their hands, most frequently to the back of the hands or web spaces. Amongst the 157 staff who wore FFP3 masks, redness of the nasal area was most frequently reported with 8% reporting facial blisters. 36% of staff reported a substantial impact on one or more aspects of their wellbeing. Only 7% of respondents had received specialist advice, yet a quarter (26%) had made or anticipated needing changes to their occupational duties. The majority (63%) felt they required no specialist input, despite 38% of these reporting a substantial detriment to their wellbeing. Handwashing and face mask use is resulting in skin damage amongst healthcare workers during the COVID-19 pandemic, with associated detriment to wellbeing. Healthcare services need to take action to implement measures to prevent, reduce and treat damage including promotion of available specialist support.

Real life data on the biopsychosocial effects of Adalimumab in the management of hidradenitis suppurativa: A multicenter cross sectional analysis and consideration of a multisystem monitoring approach to follow up.

Hidradenitis suppurativa (HS) is a chronic relapsing, remitting disease which results in the formation of inflammatory nodules and pustules in intertriginous areas. HS is a complex disease with known psychosocial impact. Adalimumab is a biologic, used for treatment resistant HS, which working by inactivating TNF-alpha. Our primary objective was to determine the effects of adalimumab on HS-PGA and DLQI scores in patients with HS that had been on the treatment for at least 6 months. Our secondary objective was to note and assess the significance of adverse effects and impacts on wider health, namely occupational and social. A retrospective cross-sectional study was performed using clinic notes from routine follow ups in biologic clinics in three specialist HS centers. About 77% (n = 78/101) patients demonstrated improvements in their HS-PGA scores. Significant improvements in the DLQI scores of the patient cohort (P = .0001, 95% CI -12.8 to -5.9) have also been demonstrated. A total of 31.7% (32/101) patients experienced adverse effects spanning multiple organ systems, with 27.7% (28/101) requiring treatment cessation. Three of these patients stopped due to the worsening of preexisting mental health symptoms. Adalimumab is effective in reducing HS-PGA and DLQI scores, but patients still complain of systemic effects necessitating drug cessation in some instances. A holistic and multisystemic approach to follow up is required, and there is scope for further studies examining temporal causality in the context of adalimumab and its multisystemic physical and psychological effects.

Paired Ear Creases of the Helix (PECH): A Possible Physical Sign.

Diagonal ear lobe creases, often known as Frank's sign, are a folding in the skin of the ear lobe. Many studies have found an association between diagonal ear lobe creases and coronary artery disease. To our knowledge, this is the first report of paired ear creases of the helix. They may have similar relevance to cardiovascular disease as the diagonal ear lobe creases. We report the case of a 68-year-old South Asian man with coronary artery disease and a diagonal ear lobe crease. On closer inspection of the auricle, he also had ear creases on the helix on the same side. We postulate that diagonal ear lobe creases and paired ear creases of the helix are formed due to pressure during sleep on a hard surface. The pathophysiological association of these creases to coronary artery disease and metabolic syndrome are not well understood. We report a new possible sign: paired ear creases of the helix which may have similar clinical significance as the diagonal ear lobe crease with respect to cardiovascular disease.

Letrozole-induced necrotising leukocytoclastic small vessel vasculitis: First report of a case in the UK.

INTRODUCTION: Letrozole, an aromatase inhibitor, is a commonly used neo-adjuvant drug to treat hormone-sensitive breast cancer. There have been a few cases of aromatase inhibitor induced vasculitis but the first case of letrozole-induced vasculitis was reported from Switzerland in 2014 (Digklia et al.) [1]. PRESENTATION OF CASE: We report the case of a 72-year-old woman with a small breast cancer. She was started on pre-operative letrozole (2.5mg/d) whilst awaiting surgery. Ten days later she presented with burning pain and purpuric skin lesions which progressed to extensive ischaemic superficial necrosis of the lower limb skin, resolving over 3-4 months after local and systemic steroids. Histologically, it showed leucocytoclasis with evidence of eosinophilia consistent with a diagnosis of cutaneous leukocytoclastic small vessel vasculitis. DISCUSSION: The initial clinical presentation was severe burning pain around the ankles and a spreading violaceous rash. Letrozole was stopped. Wide local excision (lumpectomy) and sentinel node biopsy were postponed because of the accompanying pneumonitis and gastrointestinal upset, and were carried out 3.5 months later. Fortunately, the tumour size did not increase, but appeared to reduce, and axillary lymph nodes remained negative, i.e., this patient's cancer outcome does not seem to have been jeopardized. CONCLUSION: Leukocytoclastic vasculitis is a hypersensitivity reaction that is usually self-resolving, though our case needed systemic steroid treatment. Letrozole is a commonly used drug in clinical practice and prescribers should be aware of this rare side effect, which in our case delayed treatment without any apparent harm and possibly reduced tumour size.
