Frontal fibrosing alopecia: survey of severity assessment methods in routine clinical practice and validation of the International Frontal Fibrosing Alopecia Cooperative Group measurement guidance.

BACKGROUND: The lack of validated and responsive outcome measures in the management of frontal fibrosing alopecia (FFA) significantly limits assessment of disease progression and treatment response over time. AIM: To understand how FFA extent and progression is currently assessed in UK specialist centres, to validate components of the International FFA Cooperative Group (IFFACG) statement on FFA assessment, and to identify pragmatic advice to improve FFA management in clinic. METHODS: Consultant dermatologists with a specialist interest in hair loss (n = 17) were invited to take part. Preferred FFA assessment methods were explored using questionnaires and clinical scenarios. Participants were asked to identify and mark the current hairline in 10 frontal and 10 temporal hairline images (Questionnaire 1), with assessment repeated 3 months later to assess intraindividual variability (Questionnaire 2) and 12 months later to test whether interindividual accuracy could be improved with simple instruction (Questionnaire 3). RESULTS: All 17 clinicians (100%) completed the questionnaire at each time interval. We identified a wide variation in assessment techniques used by our experts. Measurements were perceived as the most accurate method of assessing frontal recession whereas photography was preferred for temporal recession. Inter-rater reliability between clinicians measuring the frontal hairline scenarios indicated a moderate strength of agreement [intraclass coefficient (ICC) = 0.61; 95% CI 0.40-0.85], yet intrarater reliability was found to be poor with wide limits of agreement (-8.71 mm to 9.92 mm) on follow-up. Importantly, when clear guidance was provided on how the hairline should be identified (Questionnaire 3), inter-rater reliability improved significantly, with ICC = 0.70, suggesting moderate agreement (95% CI 0.51-0.89; P < 0.001). A similar pattern was seen with temporal hairline measurements, which again improved in accuracy with instruction. CONCLUSION: We found that accuracy of measurements in FFA can be improved with simple instruction and we have validated components of the IFFACG measurement recommendations.

Management of nail psoriasis.

Nail involvement is estimated to affect 80-90% of patients with psoriasis at some point in their lives and is often associated with severe disease. Patients with nail involvement experience pain, functional impairment and social stigma, with significant restriction of daily activities and quality of life. Nail psoriasis is also considered a risk factor for the development of psoriatic arthritis (PsA). Management of nail psoriasis is deemed challenging and as a result, it is often left untreated by physicians. Assessing the severity of nail disease can also be difficult in clinical practice. While the Nail Psoriasis Severity Index is used widely in trials, it is time-consuming and rarely used in the clinic, highlighting the need to develop a simplified disease severity score for nail psoriasis. All patients should be advised to keep their nails short, wear gloves for wet and dirty work, and regularly apply emollient to the nail folds and nail surface. Patients with mild nail psoriasis, without signs of severe cutaneous psoriasis or PsA, may benefit from topical treatment, while systemic treatment is indicated in patients with severe nail involvement. Evidence suggests that all anti-tumour necrosis factor (TNF)-α, anti-interleukin (IL)-17, and anti-IL-12/23 antibodies available for plaque psoriasis and PsA are highly effective treatments for nail psoriasis. This article aims to provide an up-to-date review of the therapeutic options currently available for the management of nail psoriasis in patients with or without skin psoriasis. Therapeutic options for the management of nail psoriasis in children will also be discussed.

Patient-reported outcome measures in nonmelanoma skin cancer of the face: a systematic review.

Nonmelanoma skin cancer (NMSC) is the most common malignancy in the western world, with an incidence of 98,000 in the U.K. Since 2009 the Department of Health (DoH) has collected patient-reported outcome measure (PROM) data following four common surgical procedures. However, a DoH PROM for NMSC does not exist. A systematic review of questionnaires published on patient concerns due to NMSC of the face was conducted. Keywords relevant to PROMs, NMSC and the facial region were comprehensively searched in medical databases. Inclusion criteria stipulated that questionnaires from relevant papers recruited patients with NMSC for both the item formulation and subsequent validation. Questionnaires were then discussed by a multispecialty skin cancer research team. Initially 2548 papers were found; after exclusion criteria were applied, 73 articles were retrieved. Four patient questionnaires for NMSC featured adequate development and validation according to the inclusion criteria. The Facial Skin Cancer Index (FSCI) was the only PROM specific to facial NMSC. Additional questionnaires identified included the Skin Cancer Quality of Life Impact Tool, Skindex, and Dermatology Life Quality Index. There is a scarcity of data relating to NMSC PROMs and appearance concerns. Only one questionnaire--the FSCI--was specific to patients with facial NMSC. We recommend nationally standardized data collection from patients with NMSC in order to create an evidence-based validated PROM for patients with facial skin cancer.

Gas chromatography: an investigative tool in multiple allergies to essential oils.

Essential or fragrant oils are volatile odourous mixtures of organic chemical compounds that are widely used in aromatherapy and in the perfume industry. Because of their frequent use, allergy to essential oils is being increasingly recognized. We report 2 cases of multiple allergies to essential oils in professional aromatherapists. Gas chromatography/mass spectrometry was used to analyse the oils in order to identify a common allergen responsible for the contact dermatitis. In both the cases, alpha- and beta-pinene were found to be the most common constituent in the oils and thus appeared to be key allergens. alpha-pinene was confirmed as an allergen on repeat patch testing with pure alpha-pinene in both cases. 12 controls tested were negative for the same. Gas chromatography-mass spectrometry was found to be an extremely useful tool that could be utilized in investigating multiple allergies to essential oils.

Co-existing actinic granuloma and giant molluscum contagiosum.

Actinic granuloma of O'Brien and giant molluscum contagiosum in immunocompetent adults are rare skin disorders. There have been no previous reports of these two conditions occurring together. We report this occurrence in a 57-year-old Caucasian woman.

Tinea capitis in two elderly women: transmission at the hairdresser.

Tinea capitis is rare in the elderly. We report cases of two elderly women who presented to our dermatology clinic within 8 weeks of each other, with scalp scaling and alopecia. In both cases, Microsporum canis grew on fungal culture of their hair, and required prolonged treatment with terbinafine. Neither of them gave a history of contact with young children or any animals. Both were fairly fit and not systemically immunocompromised. However, both had been regularly visiting the same hairdresser, during the presumed period of infectivity, making this the most likely source of infection.

Imiquimod 5% cream for the treatment of superficial and nodular basal cell carcinoma: randomized studies comparing low-frequency dosing with and without occlusion.

BACKGROUND: Imiquimod 5% cream has been investigated for non-surgical treatment of superficial and nodular basal cell carcinoma (BCC) tumours. OBJECTIVES: Two studies were conducted to examine the effect of occlusion at low dosing frequencies on the safety and efficacy of topical imiquimod 5% cream for the treatment of superficial and nodular BCC. PATIENTS AND METHODS: Both open-label studies were conducted in Europe. Patients diagnosed with BCC were enrolled into either the superficial (93 patients) or nodular (90 patients) study, depending on the histological confirmation of the patient's tumour subtype. Patients were randomized to one of four groups to apply imiquimod 5% cream 2 or 3 days per week either with or without occlusion. Six weeks following a 6-week treatment period, the entire target tumour area was excised and histologically examined for evidence of residual tumour. RESULTS: In both studies, the highest histologically complete response rate was seen in the 3 days per week with occlusion groups, with complete response rates of 87% and 65% for the superficial and nodular studies, respectively. Occlusion did not have a statistically significant effect on response rate at either dosing frequency. Response rates for superficial and nodular BCC tumours treated 3 days per week without occlusion were 76% and 50%, respectively. CONCLUSIONS: In the superficial study, the complete response rate of 87% in the 3 days per week with occlusion group was similar to that of daily and 5 days per week dosing without occlusion in a previous 12-week study and one study of daily dosing without occlusion for 6 weeks. All treatment groups had acceptable safety profiles in both studies. Occlusion did not have a statistically significant effect on efficacy for either superficial or nodular BCC tumours.

Efficacy and tolerability of borage oil in adults and children with atopic eczema: randomised, double blind, placebo controlled, parallel group trial.

OBJECTIVE: To study the efficacy and tolerability of borage oil, which contains a high concentration of gamma linolenic acid, in children and adults with atopic eczema. DESIGN: Single centre, randomised, double blind, placebo controlled, parallel group trial. SETTING: Acute district general hospital in Nuneaton, England. PARTICIPANTS: 151 patients, of whom 11 failed to return for assessment, leaving an evaluable population of 140 (including 69 children). INTERVENTION: Adults received four capsules of borage oil twice daily (920 mg gamma linolenic acid), and children received two capsules twice daily, for 12 weeks. MAIN OUTCOME MEASURES: Change in total sign score at 12 weeks measured with the six area, six sign, atopic dermatitis (SASSAD) score (primary endpoint); symptom scores, assessed on visual analogue scales; topical corticosteroid requirement, assessed on a five point scale; global assessment of response by participants; adverse events and tolerability. RESULTS: The mean SASSAD score fell from 30 to 27 in the borage oil group and from 28 to 23 in the placebo group. The difference between the mean improvements in the two groups was 1.4 (95% confidence interval -2.2 to 5.0) points in favour of placebo (P = 0.45). No significant differences occurred between treatment groups in the other assessments. Subset analysis of adults and children did not indicate any difference in response. The treatments were well tolerated. CONCLUSION: Gamma linolenic acid is not beneficial in atopic dermatitis.

Azathioprine in severe adult atopic dermatitis: a double-blind, placebo-controlled, crossover trial.

BACKGROUND: There is a limited range of treatments for severe atopic dermatitis (AD). Azathioprine has often been used but there has been no randomized controlled trial of this drug to confirm its efficacy in AD. OBJECTIVES: To establish or refute the efficacy of azathioprine in severe AD. To investigate the safety and tolerability of azathioprine in this patient population. METHODS: We performed a double-blind, randomized, placebo-controlled, crossover trial of azathioprine in adult patients with severe AD. Each treatment period was of 3 months' duration. Treatments were azathioprine 2.5 mg kg(-1) day(-1) and matched placebo. Disease activity was monitored using the SASSAD sign score. In addition, severity of pruritus, sleep disturbance and disruption of work/daytime activity were monitored using visual analogue scales. Adverse events were recorded and haematological and biochemical monitoring was performed. RESULTS: Thirty-seven subjects were enrolled, mean age 38 years (range 17-73). Sixteen were withdrawn, 12 during azathioprine treatment and four during placebo treatment. The SASSAD score fell by 26% during treatment with azathioprine vs. 3% on placebo (P < 0.01). Pruritus, sleep disturbance and disruption of work/daytime activity all improved significantly on active treatment but not on placebo. The difference in mean improvement between azathioprine and placebo was significant for disruption of work/daytime activity (P < 0.02) but not for pruritus or sleep disturbance. Gastrointestinal disturbances were reported by 14 patients during azathioprine treatment and four were withdrawn as a result of severe nausea and vomiting. Leukopenia was observed in two patients and deranged liver enzymes in eight during treatment with azathioprine. CONCLUSIONS: Azathioprine is an effective and useful drug in severe AD although it is not always well-tolerated. Monitoring of the full blood count and liver enzymes is advisable during treatment.
