Atypical Type 2 Lepra Reaction Masquerading as Recurrent Sweet Syndrome.

Erythema nodosum leprosum (ENL) is an immune complex-mediated response in Mycobacterium leprae infection, presenting with fever, arthralgias, and tender cutaneous lesions. It mimics Sweet syndrome (SS) clinically and histologically but requires distinct management. A 65-year-old man with recent travel presented with fever and edematous plaques.

Psychological Interventions Are More Effective Than Educational Interventions at Improving Atopic Dermatitis Severity: A Systematic Review.

We determined which educational and/or psychological interventions were most effective in atopic dermatitis (AD). A systematic review of published studies evaluated the effectiveness of educational and/or psychological interventions in MEDLINE, Embase, SCOPUS, LILACS, Cochrane, China National Knowledge Infrastructure, Taiwan Electronic Periodical Services, and CiNii. Two reviewers conducted title/abstract, full-text review, and data extraction.

Infantile myofibromatosis: multiple firm nodules in a premature newborn.

Infantile myofibromatosis is a rare myofibroblastic proliferative disorder characterized by firm, skin-colored to red-purple cutaneous and subcutaneous nodules; these are the most prevalent fibrous tumors observed in infancy. A premature male infant presented at birth with multiple subcutaneous firm skin-colored nodules measuring about 1-2cm each. Full body MRI and excisional biopsy of the right chest nodule confirmed the diagnosis.

Flexibility of the Head-Stalk Linker Domain of Paramyxovirus HN Glycoprotein Is Essential for Triggering Virus Fusion.

Unlabelled: The Paramyxoviridae comprise a large family of enveloped, negative-sense, single-stranded RNA viruses with significant economic and public health implications. For nearly all paramyxoviruses, infection is initiated by fusion of the viral and host cell plasma membranes in a pH-independent fashion. Fusion is orchestrated by the receptor binding protein hemagglutinin-neuraminidase (HN; also called H or G depending on the virus type) protein and a fusion (F) protein, the latter undergoing a major refolding process to merge the two membranes.

Mutagenesis of Paramyxovirus Hemagglutinin-Neuraminidase Membrane-Proximal Stalk Region Influences Stability, Receptor Binding, and Neuraminidase Activity.

Unlabelled: Paramyxoviridae consist of a large family of enveloped, negative-sense, nonsegmented single-stranded RNA viruses that account for a significant number of human and animal diseases. The fusion process for nearly all paramyxoviruses involves the mixing of the host cell plasma membrane and the virus envelope in a pH-independent fashion. Fusion is orchestrated via the concerted action of two surface glycoproteins: an attachment protein called hemagglutinin-neuraminidase (HN [also called H or G depending on virus type and substrate]), which acts as a receptor binding protein, and a fusion (F) protein, which undergoes a major irreversible refolding process to merge the two membranes.

Dasatinib in solid tumors.

Importance Of The Field: Dasatinib is an oral, potent adenosine triphosphate-competitive inhibitor of multiple tyrosine kinases including BCR-ABL, c-KIT, platelet-derived growth factor receptor, and Src family kinases (SFKs). It has gained much attention for its use in chronic myeloid leukemia and for the treatment of adults with Philadelphia chromosome-positive acute lymphoblastic leukemia. However, dasatinib is also being explored in solid tumors in ongoing Phase I and II clinical trials.

Src kinases as therapeutic targets for cancer.

Src family kinases (SFKs) have a critical role in cell adhesion, invasion, proliferation, survival, and angiogenesis during tumor development. SFKs comprise nine family members that share similar structure and function. Overexpression or high activation of SFKs occurs frequently in tumor tissues and they are central mediators in multiple signaling pathways that are important in oncogenesis.
