Knowledge of community pharmacists on infantile haemangioma: Gaps and lack confidence to deliver propranolol still need to be filled.

AIM: To evaluate the knowledge, practices and self-confidence of community pharmacists, pharmacy technicians and pharmacy students about infantile haemangioma (IH) and propranolol treatment. METHODS: A national survey was conducted in France from May 2022 to October 2022. A 42-item online questionnaire was used to assess pharmacists' knowledge of the epidemiology, clinical features and management of IH and propranolol treatment. RESULTS: The survey included 255 participants. The mean age was 34.9 years (±9.0); 225 (88%) were women. In all, 193 (76%) practised in urban pharmacies. Altogether, 83 participants (33%) had delivered oral propranolol solution for IH in the last 6 months. Participants' median score for self-confidence regarding propranolol dispensing was five (interquartile range, 2.5-6) on a scale of 1 to 10. Overall, 96 (38%) had more than 50% correct answers on the questionnaire. Multinomial regression models showed high scores on the questionnaire associated with high self-confidence when delivering oral propranolol solution, low number of years since graduation and having already delivered propranolol treatment. CONCLUSION: This study highlights a lack of knowledge of IH and modalities of propranolol treatment by community pharmacists and slight self-confidence when delivering propranolol. Greater cooperation between healthcare professionals could improve the proper use of medicine.

Clinical Manifestations and Management of Pediatric Granuloma Annulare: A Systematic Review.

OBJECTIVE: To determine the clinical manifestations, management, and outcomes of pediatric granuloma annulare (GA). STUDY DESIGN: We searched MEDLINE via PubMed, Latin American and Caribbean Health Sciences, and EMBASE from inception to January 2021. We included all original reports of patients <18 years of age with a diagnosis of GA and all original reports describing any intervention, including topical or systemic agents, in these patients. Two authors independently extracted sociodemographics and clinical data of the study patients and treatment(s) used. RESULTS: Of 2440 reports screened, 202 were included (836 patients). The mean age was 5.7 (SD 3.8) years and F:M ratio 1.3:1. Localized GA (n = 384/821, 46.8%) and subcutaneous GA (n = 353/821, 43.0%) were the most prevalent subtypes. The most affected site was lower limbs (n = 272/568, 47.9%). Suspected triggering factors were mainly local trauma. Diabetes was associated in 22 (2.6%) patients. The rate of spontaneous remission was high (n = 140/155, 90.3%), with a median time of 12 months. The most frequent therapies were surgery and topical corticosteroids. Recurrence was observed in 38.3% (n = 168/439) of patients, regardless of treatment. CONCLUSIONS: Pediatric GA frequently resolves spontaneously yet displays a high recurrence rate. Hence, in asymptomatic forms, invasive therapies are not recommended as first-line treatment.

Designs used in published therapeutic studies of rare superficial vascular anomalies: a systematic literature search.

BACKGROUND: Rare superficial vascular anomalies represent a wide range of diseases. Their management is difficult given the broad spectrum and the lack of clinical trials assessing treatment efficacy. A randomized clinical trial of vascular anomalies is difficult because of the rarity of the diseases and is enhanced by the population of interest often being children. Therefore, suitable designs are needed. We conducted a methodological systematic literature search to identify designs implemented for investigating the treatment of rare superficial vascular anomalies. METHODS: We conducted a literature search on January 25, 2021, of the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, ClinicalTrials.gov and European Union Clinical Trials Register databases. This systematic methodological literature search was registered at the Prospective Register of Systematic Reviews (PROSPERO: CRD42021232449). Randomized and non-randomized studies were included if they met the following criteria: were prospective studies of rare superficial vascular anomaly therapies, dealt with humans (adults and children) and were published in English from 2000. We excluded case reports/case series reporting fewer than 10 patients, reviews, retrospective studies, animal studies, studies of systemic or common vascular anomalies and non-therapeutic studies. We did not assess risk of bias in the included studies because our review was a methodological one focused on the design used. The review provided a descriptive analysis of relevant features of eligible research studies. RESULTS: From 2046 articles identified, we included 97 studies (62 reports and 35 ongoing studies): 25 randomized controlled studies, 7 non-randomized comparative studies, 64 prospective cohorts and 1 case series. Among the 32 comparative studies included, 21 used a parallel-group design. The 11 other studies used different designs such as cross-over, randomized placebo phase, delayed-start, within-person, or challenge-dechallenge-rechallenge or used a historical control group or an observational run-in period. CONCLUSIONS: Our systematic literature search highlights the lack of randomized control trials in superficial vascular anomalies due to the rarity of patients and their heterogeneity. New designs are emerging and can overcome the limitations of testing treatments in parallel groups.

Design and Methodological Issues of Within-Person (Split-Body) Randomized Controlled Trials Evaluating a Topical Treatment: A Systematic Review.

BACKGROUND: Topical drugs are often used as first-line treatment for dermatological conditions. A within-person design may then be well adapted: it consists of randomizing lesions/body sites rather than patients, which are then concomitantly treated by the different drugs compared, reducing inter-group variability and therefore requiring fewer patients than the classical parallel-group trial. OBJECTIVES: The aim of this review was to provide a methodological overview of within-person randomized trials (WP-RCTs) in dermatology. METHODS: We searched for eligible trials published between 2017 and 2021 in MEDLINE, Embase, and Central in dermatology journals and the 6 highest-impact-factor general medical journals. Two authors selected publications and extracted data independently. RESULTS: From 1,034 articles identified, we included 54 WP-RCTs, mainly for acne vulgaris, psoriasis, actinic keratosis, and atopic dermatitis. In most of the trials, patients had only 2 lesions/body sites. In none of the trials, did we detect a potential carry-across effect (known to be the major methodological problem in WP-RCTs). Twelve studies reported a care provider applying the treatment, and in 26 studies, the patients themselves applied the treatment. Finally, we also highlight statistical issues for the statistical analysis: overall, 14 (26.9%) studies used a test for independent observations, thus ignoring the between-lesion correlation. CONCLUSION: Our systematic review highlights that despite the publication of the CONSORT checklist extension for WP-RCTs in 2017, this design is rarely used, and when it is, there are methodological and reporting concerns.

Indication for a Pneumocystis Prophylaxis Therapy in Patients with Vascular Anomalies Treated with PIK3/AKT/mTOR Pathway Inhibitors: Experts' Opinion and Systematic Review from the Literature.

BACKGROUND: Vascular anomalies (VAs) are increasingly being treated with PI3K/AKT/mTOR pathway inhibitors. These drugs have immunosuppressive properties and thus theoretically overexpose patients to opportunistic infections, especially Pneumocystis jirovecii pneumonia (PJP). PJP prophylaxis use lacks consensus. We aimed to investigate the prevalence of PJP in patients receiving mTOR/PI3K/AKT inhibitors for VAs and determine any indication for pneumocystis prophylaxis in this population. METHODS: The study was conducted in 2 parts: (1) we sent a survey to a panel of international experts of VAs asking about their use of pneumocystis prophylaxis drugs and (2) we performed a systematic review of the literature of all published cases of patients receiving these drugs for VA to estimate the prevalence of PJP in this population. RESULTS: Answers from 68 experts were analyzed: 21 (30.9%) answered they always add PJP prophylaxis when prescribing mTOR inhibitors, 20 (29.4%) case-by-case, and 27 (39.7%) never. For the systematic review, among 3,053 reports screened, 217 were included involving 1,189 patients (1,143 received sirolimus, 38 everolimus, 4 alpelisib, 4 miransertib). Among the 1,189 cases, 2 (0.2%) PJP were reported: one under sirolimus and one under everolimus. Thus, the prevalence of PJP was estimated at 0.88 cases/1,000 patients under sirolimus (95% CI: -0.84 to 2.59) and 26.31 cases/1,000 under everolimus (95% CI: -24.58 to 77.18). Patients with PJP never received prophylaxis drugs. We found no PJP cases under alpelisib and miransertib. PJP prophylaxis was given in 218 (18.3%) cases, more frequently for children (91.3 vs. 77.2% in the non-prophylaxis group, p = 0.012), mostly trimethoprim-sulfamethoxazole (186 patients, 85.3%). CONCLUSION: Our study shows that even if PJP is a rare event, it may occur in patients with VAs treated with an mTOR inhibitor. Although our results cannot allow for revising guidelines, prophylaxis with TMP-SMX might be appropriate for a subgroup of patients with risk factors for PJP.

Accurate diagnosis of acute hemorrhagic edema of infancy: a French multicenter observational study.

The purpose of the study is to highlight clinical signs that are either suggestive of or against the diagnosis of AHEI to improve diagnosis and management. The medical records of children under 3 years old diagnosed with AHEI were retrospectively reviewed. Clinical data and photographs were reviewed by three independent experts, and the cases were classified as probable, doubtful, or unclear AHEI. Of the 69 cases of children diagnosed with AHEI included in 22 centers, 40 were classified as probable, 22 as doubtful, and 7 as unclear. The median age of patients with probable AHEI was 11 months [IQR 9-15], and they were in overall good condition (n = 33/40, 82.5%). The morphology of the purpura was targetoid in 75% of cases (n = 30/40) and ecchymotic in 70% of cases (n = 28/40) and affected mostly the legs (n = 39/40, 97%), the arms (n = 34/40, 85%), and the face (n = 33/40, 82.5%). Edema was observed in 95% of cases and affected mostly the hands (n = 36/38, 95%) and feet (n = 28/38, 74%). Pruritus was absent in all patients with probable AHEI and described for 6/21 with doubtful AHEI (29%). AHEI was the original diagnosis in only 24 patients (n = 24/40, 60%). The major differential diagnoses were purpura fulminans and urticaria multiforme.  Conclusion: AHEI, which the diagnosis is made on clinical findings, is often misdiagnosed. Purpuric lesions localized on the face/ears, arms/forearms, and thighs/legs with edema of the hands without pruritus in a young child with a good overall condition are highly suggestive of AHEI. What is Known: •Acute hemorrhagic edema of infancy (AHEI) is a cutaneous leukocytoclastic vasculitis affecting children under 3 years old. •Appropriate diagnosis is important to distinguish this benign disease from more serious diseases to avoid investigations and treatments, iatrogenic harm and unnecessary follow-up. What is New: •AHEI is an uncommon disorder often misdiagnosed by pediatricians and dermatologists. •Purpuric lesions localized on the face/ears, arms/forearms, and thighs/legs with edema of the hands without pruritus in an infant with a good overall condition are highly suggestive of AHEI.

Predator and Alien: the threat of predatory journals and conferences.

Predatory journals, first recognized in the early 2000s, are fraudulent publications characterized by aggressive marketing solicitations and deviation from best publishing practices. These journals claim to be legitimate scholarly publications, and accept articles with no or poor peer review processes or quality checks, with rapid publication on payment by authors. They are a global threat as they are dishonest, lack transparency and seek only financial gain. More recently, predatory conferences have emerged and are expanding rapidly. Although they appear to be legitimate scientific conferences, they are also characterized by an overriding profit motive, with no concern for academic values. Predatory journals and conferences are on the rise; dermatology trainees, readers and those new to publishing and conferences are vulnerable to predatory exploitation. The consequences of falling victim to such predation include damage to the external reputation of the authors and their institution, and heightened concerns about the legitimacy of the research. This educational review defines predatory journals and conferences, and summarizes their distinguishing features such as a poor or no peer review process, rapid acceptance, flattering language and lack of meeting. It highlights the consequences of publishing in a predatory journal or attending a predatory conference, and outlines several tools available that dermatology researchers can use to recognize and reduce the likelihood of falling prey to a predatory journal or conference.

Factors associated with efficacy of botulinum toxin a injections in primary axillary hyperhidrosis: A retrospective study of ninety patients.

Primary focal hyperhidrosis (PFH) is a frequent condition which can seriously affect the quality of life. Intradermal injections of botulinum toxin A (BTA) is a safe temporary treatment. The objective was to assess the factors associated with the efficacy of the axillary injections of abobotulinumtoxinA in PFH. Among a cohort of 236 patients followed for axillary injections of BTA between 2001 and 2020 for severe PFH, we included patients treated with 150 units per armpit of abobotulinumtoxinA with a minimum follow-up of three years. We described the characteristics of the patients and then searched for association between variables (sex, age, multifocal PFH and duration of efficacy of the first injection [<6 or ≥6 months]) and the number of injections received in three years, counted at the second injection date, by univariate and multivariate logistic regression. Ninety patients were included (62 women, median age of 29 years and 12.2% of multifocal PFH). The median duration of efficacy of the first injection was six months (interquartile range 3-9). The duration of efficacy of the first injection ≥6 months was significantly associated with less injections during the 3-year follow-up in univariate (odds ratio [OR]: -1.18 [95% confidence interval (CI): -1.80 to -0.55]; p < 0.01) and multivariate (OR: -1.16 [95% CI: -1.79 to -0.53]; p < 0.01) logistic regression. There was no significant difference with female sex, age, or multifocal PFH. A duration of efficacy of the first injection greater than six months seems to indicate a better response profile to BTA.

Short-term Effect and Acceptability of Manual Lymphatic Drainage for Paediatric Limb Lymphoedema: A Prospective Study.

Paediatric lymphoedema (LE) is a rare condition, for which there is little data available regarding treatments. The aim of this study was to assess the short-term effect and acceptability of a 30-min session of manual lymphatic drainage (MLD) in children with well-documented LE of the lower limbs. Fifteen children were included (8 males; median age 11 years). Comparison of the sum of circumference values for the whole limb before and after MLD revealed a slight, but significant, reduction (from a median of 289.8 to 285.5 cm, p = 0.024), but the limb volumes did not decrease significantly (from a median of 4,870.3 to 4,772.3 ml, p = 0.394). Dermal thickness, measured by high-resolution ultrasound, decreased from 1.44 to 1.40 mm (p < 0.001). All children reported improvement in well-being, and found MLD useful. In conclusion, MLD is well accepted by children, but has poor impact on LE swelling. However, it decreases cutaneous oedema by mobilizing the lymph fluid.

Topical use of mammalian target of rapamycin inhibitors in dermatology: A systematic review with meta-analysis.

BACKGROUND: Systemic mammalian target of rapamycin (mTOR) inhibitors are currently used in many dermatologic indications. Their topical use is recent and poorly codified. OBJECTIVE: To provide an overview of the topical use of mTOR inhibitors in dermatologic conditions and evaluate their efficacy and safety. METHODS: A literature search was performed in January 2017. Reports of all studies investigating the use of topical mTOR inhibitors in any dermatology diseases were included. The exclusion criteria were systemic use and mucosal administration. RESULTS: We included 40 studies with a total of 262 patients. In all, 11 dermatologic conditions were found, the most frequent being angiofibromas linked to tuberous sclerosis complex (157 patients). Topical mTOR inhibitors were significantly more efficient than placebo for angiofibromas (relative risk, 2.52; 95% confidence interval, 1.27-5.00; I2 = 0%). The median concentration of sirolimus was 0.1%, with a median treatment duration of 12 weeks. Topical mTOR inhibitors were well tolerated, with only mild or moderate local side effects (mostly irritative) reported. Blood level of sirolimus was not detected in 90% of patients. LIMITATIONS: High heterogeneity in most studies. CONCLUSION: This systematic review supports the efficacy of topical sirolimus for angiofibromas linked to tuberous sclerosis complex, with only local side effects reported. Other indications require further research.

Prevalence of Nail Scabies: A French Prospective Multicenter Study.

INTRODUCTION: To assess the prevalence of nail involvement in children <16 years old with a confirmed diagnosis of scabies. STUDY DESIGN: Observational, prospective study in 7 French dermatology departments between June 2015 and January 2017. Children were included if they had scabies confirmed by dermoscopy and/or microscopy and if nails could be sampled. The first toenails and thumbnails as well as clinically affected nails were systematically sampled for microscopic examination. Individual data were recorded via a standardized questionnaire. RESULTS: A total of 47 children with scabies were included (26 females [55.3%], mean age 3.6 ± 4.0 years). Pruritus was present in 42 children (89.3%); the relapse rate was 38.3% (n = 18). In 3 infants (6.4%), Sarcoptes mites were revealed by dermoscopy or microscopy of the first toenails (2 cases) and a thumbnail (1 case), but nails were normal in 2 children. Two of the 3 infants had already received treatment for scabies in the previous weeks. CONCLUSION: Prevalence of nail involvement in children with confirmed scabies was 6.4%. Nails should not be overlooked during scabies treatment.

Search for RASA1 Variants in Capillary Malformations of the Legs in 113 Children: Results from the French National Paediatric Cohort CONAPE.

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) of the legs, whatever the associated abnormalities, and to identify genotype-phenotype correlates. DNA was extracted from leukocytes in blood samples, purified and amplified, and all exons of the RASA1 gene were analysed. Among 113 children analysed, 7 had heterozygous variants (6.1%). Four different variants were identified; 2 were new. In children with RASA1 variants, CMs were more frequently bilateral and multifocal. In conclusion, RASA1 variants are rarely found in children with sporadic CM of lower limbs without CM-AVM syndrome. CMs in this study were heterogeneous, and no disease-causing relationship could be proven.
