RESUMO
BACKGROUND: European guidelines propose a 0·5 mg kg-1 per day dose of oral prednisone as initial treatment for bullous pemphigoid (BP). We assessed the safety and efficacy of this regimen depending on BP extent and general condition of the patients. METHODS: In a prospective international study, we consecutively included all patients diagnosed with BP. Patients received a 0·5 mg kg-1 per day dose of prednisone, which was then gradually tapered 15 days after disease control, with the aim of stopping prednisone or maintaining minimal treatment (0·1 mg kg-1 per day) within 6 months after the start of treatment. The two coprimary endpoints were control of disease activity at day 21 and 1-year overall survival. Disease severity was assessed according to the Bullous Pemphigoid Disease Area Index (BPDAI) score. RESULTS: In total, 198 patients were included between 2015 and 2017. The final analysis comprised 190 patients with a mean age of 80·9 (SD 9·1) years. Control of disease activity was achieved at day 21 in 119 patients [62·6%, 95% confidence interval (CI) 55·3-69.5]; 18 of 24 patients (75%, 95% CI 53·3-90·2), 75 of 110 patients (68·8%, 95% CI 59·2-77·3) and 26 of 56 patients (46.4%, 95% CI 33·0-60·3) had mild, moderate and severe BP, respectively (P = 0·0218). A total of 30 patients died during the study. The overall Kaplan-Meier 1-year survival was 82·6% (95% CI 76·3-87·4) corresponding to 90·9%, 83·0% and 80·0% rates in patients with mild, moderate and severe BP, respectively (P = 0·5). Thresholds of 49 points for BPDAI score and 70 points for Karnofsky score yielded maximal Youden index values with respect to disease control at day 21 and 1-year survival, respectively. CONCLUSIONS: A 0·5 mg kg-1 per day dose of prednisone is a valuable therapeutic option in patients with mild or moderate BP whose general condition allows them to be autonomous.

BACKGROUND: Venous leg ulcers (VLUs) often take a very long time to heal. Timolol maleate has been reported as displaying efficacy in healing of VLUs. OBJECTIVES: To evaluate the efficacy of timolol maleate gel in the management of hard-to-heal VLUs and to assess its safety as a topical agent during 12 weeks of use in combination with conventional treatment. METHODS: A prospective, phase-II randomised-controlled trial with a sample size based on Fleming's one-stage design (P0=0.25, P1=0.45, alpha=0.1, beta=0.2) was planned. Patients with VLUs present for ≥24 weeks and with ≥50% granulation tissue were included. One drop of sustained-release timolol gel (Timoptol® LP 0.5%, Santen, Tampere, Finland) per 6 cm2 VLU area was applied every 2 days for 12 weeks in timolol-treated patients, as adjuvant therapy to the standard care protocol (interface dressing and multilayer venous compression). Controls received standard care alone. The primary endpoint was to obtain ≥40% reduction in ulcer area at week 12 (W12). RESULTS: Forty-three patients were randomised to the study, with 40 receiving at least one treatment and included in the analysis: 21 timolol-treated patients and 19 controls (females: 70%; median age: 72.5 [range 35-93] years). At W12, ≥40% ulcer-area reduction was achieved in 14/21 (67%) timolol-treated patients vs. 6/19 (32%) controls. No serious adverse events occurred. Local wound infections not requiring systemic antibiotics occurred in 5 cases in the timolol group and in one case in the controls. CONCLUSIONS: These results support the benefit and safety of using timolol maleate to manage hard-to-heal VLUs, but confirmation is required in a larger multicentre randomised phase-III study.

Vedolizumab is a humanized monoclonal antibody that binds to the human a4ß7 integrin and is approved for use in inflammatory bowel diseases. We describe a patient with severe, refractory erosive gingivostomatitis, which appeared a few days after the first dose of vedolizumab and resolved after discontinuation of the drug. We believe the gingivostomatitis to be a direct side effect of vedolizumab, rather than an extraintestinal manifestation of the underlying inflammatory bowel diseases. The clinicians need to be aware of this adverse event, which could be mistakenly considered as an extraintestinal manifestation of inflammatory bowel diseases.

BACKGROUND: Collagen stimulators such as Ellansé® are soft tissue fillers able to induce nucleogenesis. We describe a case of eruptive foreign body granulomas following injection of Ellansé® that were successfully treated using methotrexate. CASE REPORT: A 47-year-old woman received injections of Ellansé® for the wrinkled aspect of her cheeks. She had previously undergone injections of hyaluronic acid on the nasolabial folds. Nine months after the Ellansé® injections, the patient consulted for the recent appearance of multiple nodules on her face. Histological analysis of one of these nodules confirmed the presence of foreign-body granulomas developed in contact with spherical gaps of a size substantially identical to the Ellansé® vacuoles. Methotrexate 10mg per week for 3 months followed by 20mg per week for 9 months resulted in complete regression of the nodules. DISCUSSION: Ellansé® is composed of two biocompatible and bioabsorbable polymers: carboxymethylcellulose, responsible for immediate volume creation, and polycaprolactone, which promotes collagen synthesis. However, any injected product can cause varying degrees of granulomatous reaction. Hyaluronic acid was previously injected at several other sites on the patient's face. These lesions were not the result of poor injection technique. CONCLUSION: Although collagen stimulators are biocompatible and bioabsorbable substances, the development of foreign-body granulomas, while rare, is still possible. Methotrexate resulted in significant regression of nodules as of the third month of treatment.

BACKGROUND: Because of its rarity, the exact incidence of and mortality from epidermal necrolysis (Stevens-Johnson syndrome/toxic epidermal necrolysis) is difficult to establish and closely depends on the size and type of the data source. OBJECTIVES: To estimate the incidence of and mortality due to epidermal necrolysis in France over a 14-year period. METHODS: Data from four national databases were analysed. A capture-recapture analysis was performed. RESULTS: A total of 2635 incident cases of epidermal necrolysis were recorded in at least one of the four databases during the study period [males: 47·9%; median age: 52 (interquartile range 25-72) years]. On capture-recapture analysis, the estimated total number of cases was 5686, for an overall estimated annual incidence of 6·5 (95% confidence interval 4·1-8·9) cases per million inhabitants. The estimated annual incidence rates were 4·1 (0·3-7·9) cases per million inhabitants < 20 years of age, 3·9 (1·5-6·3) cases per million inhabitants aged 20-64 years and 13·7 (5·4-22·0) cases per million inhabitants ≥ 65 years of age. The estimated overall annual mortality rate from epidermal necrolysis was 0·9 (0·1-1·8) case per million inhabitants. It was 0·6 (0·1-1·5) case per million inhabitants aged 20-64 years and 2·8 (0·9-6·6) cases per million inhabitants ≥ 65 years of age (deaths in people < 20 years old were too rare to provide an accurate estimate). CONCLUSIONS: The annual incidence of epidermal necrolysis is higher than the one to five cases per million inhabitants usually reported. Such estimations could be helpful in establishing appropriate healthcare plans for people with epidermal necrolysis, in particular the need for specialized care units. What's already known about this topic? Few data are available regarding incidence of and mortality from epidermal necrolysis in the general population. Experts in epidermal necrolysis have recently proposed an annual incidence of one to five cases per million individuals. The overall mortality rate is usually reported to be between 10% and 20%. What does this study add? Using a four-source capture-recapture method and data from a 14-year period (2003-16), the annual incidence of and mortality from epidermal necrolysis were estimated to be 6·5 (95% confidence interval 4·1-8·9) and 0·9 (0·1-1·8) cases per million French inhabitants, respectively. Such estimations could be helpful in establishing appropriate healthcare plans, in particular the need for specialized care units.

BACKGROUND: Tattooing is a widespread phenomenon, with an estimated prevalence of 10-30% in Western populations. For psoriasis patients, current recommendations are to avoid having a tattoo if the disease is active and they are receiving immunosuppressive treatments. Although scientific data supporting these recommendations are lacking, dermatologists are often reluctant to advocate tattooing in psoriasis patients. OBJECTIVE: We aimed to evaluate the frequency of tattoo complications in patients with psoriasis and determine whether the occurrence of complications was associated with psoriasis status and treatments received at the time of tattooing. METHODS: We performed a multicentre cross-sectional study. Adults with psoriasis were consecutively included and classified as tattooed or non-tattooed. Prevalence of complications associated with tattoos was then evaluated according to psoriasis onset and treatments. The study was divided into three parts, in which data were collected through a series of questionnaires filled in by the dermatologist. Complications included pruritus, oedema, allergic reaction/eczema, infection/superinfection, granuloma, lichenification, photosensitivity, Koebner phenomenon and psoriasis flare after tattooing. Diagnosis of complications was made retrospectively. RESULTS: We included 2053 psoriatic patients, 20.2% had 894 tattoos. Amongst non-tattooed patients, 15.4% had wished to be tattooed, with psoriasis being stated as a reason for not having a tattoo by 44.0% and 5.7% indicating that they planned to have a tattoo in the future. Local complications, such as oedema, pruritus, allergy and Koebner phenomenon, were reported in tattoos in 6.6%, most frequently in patients with psoriasis requiring treatment at the time of tattooing (P < 0.0001). No severe complications were reported. CONCLUSIONS: The rate of tattoo complications in psoriasis patients was low. Although the risk of complications was highest amongst patients with psoriasis requiring treatment at the time of tattooing, all the complications observed were benign. These results can be helpful for practitioners to give objective information to patients.

BACKGROUND: Partial 21q monosomy is a rare condition with only a few cases being described in the literature. We report a new case associating congenital alopecia with 21q deletion. PATIENTS AND METHODS: At birth, a female infant presented with diffuse alopecia, atrichia of the eyelashes and eyebrows, and deformed ears. Her development was marked by the appearance of intellectual deficit. Chromosome analysis by karyotype and CGH (comparative genomic hybridization) array revealed ring chromosome 21 with 21q22.3 terminal deletion of 3.6 Mb. The other laboratory examinations were unremarkable, and simply ruled out the main differential diagnoses. Treatment with zinc and Minoxidil® 5% allowed regrowth of lightly pigmented down on the scalp alone. DISCUSSION: A combination of alopecia, deformed ears and mental retardation should suggest a diagnosis of partial 21q monosomy. Alopecia, which is poorly described in this syndrome, seems to be more frequently associated with 21q22.3 terminal involvement.

BACKGROUND: Three biotherapies - etanercept, adalimumab and ustekinumab - are licensed in childhood psoriasis. The few data available on their efficacy and tolerance are mainly derived from industry trials. However, biological drug survival impacts long-term performance in real-life settings. OBJECTIVE: The objective of this study was to evaluate the survival rates of biological therapies in children with psoriasis in real-life conditions. Secondary objectives were to evaluate the factors associated with the choice of the biological therapy and to report severe adverse events. MATERIALS AND METHODS: This study was an observational retrospective study. Data were extracted from the clinical records of 134 children. Kaplan-Meier estimates were used to analyse drug survival overall and in subgroups of plaque psoriasis, bio-naïve and non-naïve patients. RESULTS: We analysed 184 treatment courses: 70 with etanercept, 68 with adalimumab and 46 with ustekinumab. Factors associated with the choice of first-line biological agent were age at initiation (younger for adalimumab, P < 0.0001), age at onset of psoriasis (younger for adalimumab and etanercept, P = 0.03) and baseline Psoriasis Assessment Severity Index and Physician global assessment (both higher for adalimumab, P < 0.001). Drug survival rates were higher for ustekinumab than for adalimumab and etanercept (P < 0.0001) for all treatment and all psoriasis types, plaque-type psoriasis (P = 0.0003), patients naïve for biological agents (P = 0.0007) and non-naïve patients (P = 0.007). We reported eight serious adverse events (SAEs): severe infections (n = 3), significant weight gain (n = 2), psoriasis flare (n = 1) and malaise (n = 1). Biological therapy was discontinued in three children (one with psoriasis flare and two with weight gain). Only the two cases of weight gain resulted in an unfavourable outcome. CONCLUSIONS: Our real-life comparative study found that ustekinumab had the best drug survival outcome. The profile of SAEs in children was comparable to that in adults. These results will assist dermatologists in the decision-making process when choosing treatment options for children with psoriasis in daily practice.

BACKGROUND: Specific trichoscopic signs of tinea capitis (TC) were first described in 2008. The accuracy of this diagnostic tool has not been evaluated. OBJECTIVES: To assess the diagnostic accuracy of trichoscopy. METHODS: A prospective, multicentre study was done between March 2015 and March 2017 at the dermatology departments of four French university medical centres. Patients with a presumed diagnosis of TC were included. Trichoscopy was considered to be positive if at least one specific trichoscopic sign was observed. Trichoscopy results were compared with the gold standard for diagnosis of TC (mycological culture). RESULTS: One hundred patients were included. Culture was positive for 53 patients and negative for 47. The sensitivity of trichoscopy was 94% [95% confidence interval (CI) 88-100], specificity was 83% (95% CI 72-94), positive predictive value was 92% and negative predictive value was 86%. Comma hairs, corkscrew hairs, zigzag hairs, Morse-code-like hairs and whitish sheath were significantly more frequent in patients with a positive mycological culture (P < 0·001). Comma hairs were more frequent in patients with Trichophyton TC (P = 0·026), and zigzag hairs were more frequent in patients with Microsporum TC (P < 0·001). Morse-code-like hair was not observed in any patients with Trichophyton TC and therefore appears to be highly specific for Microsporum TC. CONCLUSIONS: The presence of a single trichoscopic finding is predictive of TC. Trichoscopy is a useful, rapid, painless, highly sensitive tool for the diagnosis of TC - even for dermoscopists with little experience of trichoscopy. It enhances physicians' ability to make treatment decisions. What's already known about this topic? Tinea capitis (TC) must be confirmed by a mycological culture that may take up to 6 weeks, delaying treatment. Specific trichoscopic signs of TC were first described in 2008, but the accuracy of trichoscopy for diagnosing TC has not previously been evaluated. What does this study add? The present series is the largest yet on the use of trichoscopy in the diagnosis of TC. Our results demonstrated that the presence of a single feature (comma hair, corkscrew hair, zigzag hair, Morse-code-like hair or whitish sheath) is predictive of TC. Trichoscopy is painless and highly sensitive. Morse-code-like hair appears to be highly specific for Microsporum TC.
