Cerebral dural arteriovenous fistulas in patients with PTEN-related hamartoma tumor syndrome.

Central nervous system (CNS) dural arteriovenous fistulas (DAVF) have been reported in PTEN-related hamartoma tumor syndrome (PHTS). However, PHTS-associated DAVF remain an underexplored field of the PHTS clinical landscape. Here, we studied cases with a PTEN pathogenic variant identified between 2007 and 2020 in our laboratory (n = 58), and for whom brain imaging was available.

Ocular involvement in pediatric Behçet's disease: is it different than in adults? (a short case series and mini review).

Background: Pediatric Behçet's disease (PBD) is rarer than BD and can be a challenging diagnosis as clinical picture may be incomplete. As in adult patients, sight-threatening ocular manifestations may lead to diagnosis. In this study, we aimed to report a series of cases of PBD with ocular manifestations and provide a review of the literature.

[Systemic sclerosis-related interstitial lung disease: Diagnostic and therapeutic strategy in the light of recent clinical trials].

Systemic sclerosis (SSc) is an autoimmune disease associated to fibrotic manifestations. Interstitial lung disease (SSc-ILD), one of the main fibrotic features of SSc, is the first cause of SSc-related death. The management of SSc-ILD has recently benefited from the results of key randomised controlled trials.

Cardiovascular and connective tissue disorder features in FLNA-related PVNH patients: progress towards a refined delineation of this syndrome.

Background: FLNA Loss-of-Function (LoF) causes periventricular nodular heterotopia type 1 (PVNH1), an acknowledged cause of seizures of various types. Neurological symptoms are inconstant, and cardiovascular (CV) defects or connective tissue disorders (CTD) have regularly been associated. We aimed at refining the description of CV and CTD features in patients with FLNA LoF and depicting the multisystemic nature of this condition.

Eczema Herpeticum: Clinical and Pathophysiological Aspects.

Atopic dermatitis (AD) is the most common chronic inflammatory skin disease in the world. AD is a complex pathology mainly characterized by an impaired skin barrier, immune response dysfunction, and unbalanced skin microbiota. Moreover, AD patients exhibit an increased risk of developing bacterial and viral infections.

Loss of Epidermal HIF-1α Blocks UVB-Induced Tumorigenesis by Affecting DNA Repair Capacity and Oxidative Stress.

HIF-1α is constitutively expressed in mouse and human epidermis. It plays a crucial role in skin physiology, including the response of keratinocytes to UVR. However, little information is available about its role in photocarcinogenesis.

Pimecrolimus in atopic dermatitis: consensus on safety and the need to allow use in infants.

Atopic dermatitis (AD) is a distressing dermatological disease, which is highly prevalent during infancy, can persist into later life and requires long-term management with anti-inflammatory compounds. The introduction of the topical calcineurin inhibitors (TCIs), tacrolimus and pimecrolimus, more than 10 yr ago was a major breakthrough for the topical anti-inflammatory treatment of AD. Pimecrolimus 1% is approved for second-line use in children (≥2 yr old) and adults with mild-to-moderate AD.

The lymphoid variant of hypereosinophilic syndrome: study of 21 patients with CD3-CD4+ aberrant T-cell phenotype.

The CD3-CD4+ aberrant T-cell phenotype is the most described in the lymphoid variant of hypereosinophilic syndrome (L-HES), a rare form of HES. Only a few cases have been reported, and data for these patients are scarce. To describe characteristics and outcome of CD3-CD4+ L-HES patients, we conducted a national multicentric retrospective study in the French Eosinophil Network.

Further documentation of spontaneous regression of infantile digital fibromatosis.

Infantile digital fibromatosis is a rare benign fibromatous tumor characterized by both its location on fingers and toes and its distinctive light microscopic appearance. However, treatment modalities are not yet standardized. Surgical excision had been preferred in the past but has the disadvantage of a high recurrence rate.
