    Abstract Background: Biologic drugs have the potential to halt the progression of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) by decreasing concentrations of tumor necrosis factor-α, a cytokine implicated in epithelial cell death. The objective of this systematic review is to investigate the efficacy and safety of biologic monotherapy and combination therapy for SJS/TEN.
    Methods: MEDLINE and EMBASE in OVID were searched on October 28, 2020. Inclusion criteria were original studies containing human participants diagnosed with SJS/TEN and treated with biologics. Studies were excluded if they were literature reviews, systematic reviews, letters to the editor, or conference abstracts.
    Results: The 38 articles reviewed included 27 (71.1%) case reports, 6 (15.8%) case series, 3 (7.9%) retrospective reviews, and 2 (5.3%) RCTs. The age range of the included studies was 2 to 85 years, the mean age was 46.4 years. The mean body surface (BSA) across the 38 included articles was 31.0%. The average actual mortality reported within the 38 included articles was 9.2%. Both biologic monotherapy and combination therapy were associated with improved outcomes in SJS/TEN. Furthermore, anti TNF-alpha therapy, specifically etanercept, showed improved outcomes as monotherapy.
    Conclusions: Overall, reviewed studies presented a strong case for biologic treatment, both monotherapy and combination use, in SJS/TEN treatment. Based on the number of fatal adverse events observed, biologic monotherapy may be safer compared to combination therapy. Further research with a larger sample size and a randomized control trial design is required.

    Abstract Breast cancer is a complex disease that comprises cancers of distinct biologies and responses to treatment. Clinical management relies on traditional clinicopathological parameters, involving lymph node status, histological grade, as well as expression of the estrogen receptor or human epidermal growth factor receptor 2. Molecular pathology as well as protein and gene expression profiling have divided breast tumors into molecular subtypes associated with different clinical outcomes. One of these, defined as basal breast cancer, is associated with poor prognosis. Molecular mechanisms involved in the induction of basal breast cancer are poorly understood and targeted therapies for this subtype are lacking. Recent evidence using murine models identified a role for the Met receptor tyrosine kinase in the induction of murine mammary tumors with characteristics of human basal breast cancers. Moreover, elevated Met protein and RNA is associated with human basal tumors and poor outcome. These studies identify a link between the Met receptor tyrosine kinase, epithelial mesenchymal transition, and basal breast cancer. In this review, we provide an overview of murine Met models in relation to the spectrum of mouse models of breast cancer and a role for the Met receptor in basal breast cancer tumorigenesis.

    Abstract Eruptive vellus hair cysts (EVHCs) often occur on the trunk and limbs. Facial involvement is uncommon. Autosomal dominant inheritance has been described, but associated extracutaneous anomalies have not. We describe a 4-patient kindred presenting with multiple facial EVHCs and an association of preauricular pits, lipomas, joint hypermobility, and cardiac defects. Histopathologic examination confirmed the diagnosis of EVHCs in 3 affected individuals. We propose that facial EVHCs may indicate the presence of an inherited autosomal dominant disorder with extracutaneous manifestations. Extracutaneous manifestations noted in the kindred have been sporadically described in association with steatocystoma multiplex (SM), a condition occasionally noted in the presence of EVHCs, further supporting an association between these disorders.

    Abstract Although several ethnic groups experience a greater burden of diabetes, this has not been examined in first-generation Italians, who compose one of the largest ethnocultural groups in Canada. In this cross-sectional study, the authors examined the relationship among gender and ethnocultural factors, family support, depressive symptomatology, and illness perceptions on diabetes self-management (DSM) in 50 Italian women and men with type 2 diabetes. The authors first conducted a focus group to explore cultural barriers. They then assessed gender, ethnocultural, and psychosocial barriers quantitatively by an interviewer-administered questionnaire. Compared with Italian men, Italian women reported significantly greater depressive symptomatology and perceived disease seriousness. Greater depressive symptomatology was significantly associated with perceived family sabotage and DSM barriers. In univariate analyses, shorter duration of diabetes and greater perceived treatment effectiveness significantly predicted better DSM. In conclusion, certain illness perceptions and culturally relevant gender-specific barriers should be addressed by health care providers to maximize DSM in this population.

    Abstract The polarised distribution of signals downstream from receptor tyrosine kinases (RTKs) regulates fundamental cellular processes that control cell migration, growth and morphogenesis. It is poorly understood how RTKs are involved in the localised signalling and actin remodelling required for these processes. Here, we show that the Gab1 scaffold is essential for the formation of a class of polarised actin microdomain, namely dorsal ruffles, downstream from the Met, EGF and PDGF RTKs. Gab1 associates constitutively with the actin-nucleating factor N-WASP. Following RTK activation, Gab1 recruits Nck, an activator of N-WASP, into a signalling complex localised to dorsal ruffles. Formation of dorsal ruffles requires interaction between Gab1 and Nck, and also requires functional N-WASP. Epithelial cells expressing Gab1DeltaNck (Y407F) exhibit decreased Met-dependent Rac activation, fail to induce dorsal ruffles, and have impaired cell migration and epithelial remodelling. These data show that a Gab1-Nck signalling complex interacts with several RTKs to promote polarised actin remodelling and downstream biological responses.
