Discrepancies in the management of acquired cold contact urticaria: Results of a French-speaking urticaria experts questionnaire survey.

Acquired cold contact urticaria (ACU) is a putatively serious condition, because of the risk of anaphylactic shock whenever patients are massively exposed to cold atmosphere/water, raising the question of the prescription of an "emergency kit" with oral antihistamines and epinephrine auto-injector. We performed an online survey to evaluate how French-speaking urticaria experts manage ACU. According to the 2016 consensus recommendations on chronic inducible urticarias, all the participants perform at least 1 of the available provocation tests and 84.

Emergence of Difficult-to-Treat Tinea Corporis Caused by Trichophyton mentagrophytes Complex Isolates, Paris, France.

We describe 7 cases of extensive tinea corporis since 2018 in a hospital in Paris, France, after failure to cure with terbinafine. Molecular analysis indicated Trichophyton mentagrophytes internal transcribed spacer type VIII (T. indotineae).

Tacrolimus 0.1% versus ciclopiroxolamine 1% for maintenance therapy in patients with severe facial seborrheic dermatitis: A multicenter, double-blind, randomized controlled study.

Background: No long-term maintenance therapy has been tested in patients with seborrheic dermatitis (SD).

Objective: We sought to compare the efficacy and tolerance of tacrolimus 0.1% ointment versus ciclopiroxolamine 1% cream as maintenance therapy for severe SD.

[Misdiagnosis of hidradenitis suppurativa continues to be a major issue. The R-ENS Verneuil study].

Objective: To provide physicians with an understanding of the factors behind significant delays in the diagnosis of hidradenitis suppurativa (HS) in France.

Patients And Methods: This prospective multicentre national study conducted from October 2015 to March 2016 included all patients consulting for HS. Patient data were collected by means of a standardized questionnaire.

Identification of three hidradenitis suppurativa phenotypes: latent class analysis of a cross-sectional study.

To identify the underlying subtypes of hidradenitis suppurativa (HS), we performed latent class analysis on prospective clinical data of 618 consecutive patients seen between 2002 and 2010. The median patient age was 31 years (Q1=26; Q3=38), median age at HS onset was 20 years (16-25), and median Sartorius score was 18 (11-19); 34.4% of patients were of Hurley stage II or III.

Combination therapy with clindamycin and rifampicin for hidradenitis suppurativa: a series of 116 consecutive patients.

Background: Antibiotics are frequently used to treat hidradenitis suppurativa (HS); however, few data on their efficacy are available.

Objective: To evaluate the efficacy of a combination of systemic clindamycin (300 mg twice daily) and rifampicin (600 mg daily) in the treatment of patients with severe HS.

Methods: Patients (n = 116) who received this combination were studied retrospectively.

Clinical characteristics of a series of 302 French patients with hidradenitis suppurativa, with an analysis of factors associated with disease severity.

Background: Factors associated with the severity of hidradenitis suppurativa (HS) are not known.

Objective: We sought to identify factors associated with the severity of HS.

Methodology: The severity of disease in a series of 302 consecutive patients with HS was assessed using the Sartorius score.

Absence of efficacy of oral isotretinoin in hidradenitis suppurativa: a retrospective study based on patients' outcome assessment.

Background: In analogy to acne, oral isotretinoin has been considered in the treatment of hidradenitis suppurativa (HS).

Objectives: To assess the efficacy of oral isotretinoin according to patients.

Methods: From 1999 to 2006, 358 consecutive HS patients were interviewed and examined.

Prevalence and factors associated with hidradenitis suppurativa: results from two case-control studies.

Background: Conflicting opinions have been reported regarding the epidemiology of hidradenitis suppurativa.

Objective: We sought to evaluate the prevalence of hidradenitis suppurativa and to identify associated factors.

Methodology: Prevalence was evaluated using a representative sample of the French population (n=10,000).

[Lymphedema as a complication of hidradenitis suppurativa in three patients].

Background: We report three patients (respectively 36, 52 and 52 years old) with a long history of hidradenitis suppurativa associated with pubic lymph oedema.

Case Report: Dramatic pubic oedema was noted, with "rugby-ball and bag-like" tumefaction associated with nodules and fistula. There was no evidence of lymph node involvement or abdominal lymphatic blockade.

Mycosis fungoides presenting as keratosis lichenoides chronica.

We report a patient with a 17-year history of reticulated keratotic papules on the trunk and limbs, and telangiectatic eruption on the face, in whom the diagnosis of keratosis lichenoides chronica was first established. However, the biopsies showed an epidermotropic infiltrate of small irregular CD4+ lymphocytes, and detection of a T-cell clone in the lesions by polymerase chain reaction confirmed the diagnosis of mycosis fungoides. Thus, keratosis lichenoides chronica can be an unusual and potentially misleading presentation of mycosis fungoides.
