Angioinvasive fungal infections cause significant morbidity and mortality because of their propensity to invade blood vessel walls, resulting in catastrophic tissue ischemia, infarct, and necrosis. While occasionally seen in immunocompetent hosts, opportunistic fungi are emerging in immunosuppressed hosts, including patients with hematologic malignancy, AIDS, organ transplant, and poorly controlled diabetes mellitus. The widespread use of antifungal prophylaxis has led to an "arms race" of emerging fungal resistance patterns. Read More

Background And Objectives: First-line treatment of chronic phase (CP) chronic myeloid leukemia (CML) is based on the first-generation tyrosine kinase inhibitor (TKI) imatinib or the second-generation TKIs dasatinib or nilotinib. Thanks to the efficacy of TKIs, CML has switched from a fatal to a 'chronic' pathology, and data from clinical trials have become insufficient to drive physicians' prescription choices and address long-term treatment outcomes. On the brink of commercialization of generic imatinib, this study aims to evaluate the therapeutic pattern of CP-CML and the occurrence of adverse events (AEs) over a decade of local real clinical practice.

The clinical manifestations of inherited susceptibility to leukemia encompass a wide phenotypic range, including patients with certain congenital anomalies or early-onset myelodysplastic syndrome (MDS) and some with no obvious medical problems until they develop leukemia. Leukemia susceptibility syndromes occur as a result of autosomal dominant, autosomal recessive, or X-linked recessive inheritance, or de novo occurrence, of germline pathogenic variants in DNA repair, ribosome biogenesis, telomere biology, hematopoietic transcription factors, tumor suppressors, and other critical cellular processes. Children and adults with cytopenias, MDS, dysmorphic features, notable infectious histories, immunodeficiency, certain dermatologic findings, lymphedema, unusual sensitivity to radiation or chemotherapy, or acute leukemia with a family history of early-onset cancer, pulmonary fibrosis, or alveolar proteinosis should be thoroughly evaluated for a leukemia susceptibility syndrome.

Dermatologic manifestations are observed in almost all systemic vasculitides, even in large-and medium-vessel vasculitides, although such vessels are not found in the skin. Cutaneous manifestations may be related to a direct skin localization of the systemic vasculitis or a non-specific process associated with the vasculitis. According to the 2012 International Chapel Hill consensus, the two major variants of large-vessel vasculitides are Takayasu arteritis and giant-cell arteritis. Read More

Autoinflammatory disorders are sterile inflammatory conditions characterized by episodes of early-onset fever, rash, and disease-specific patterns of organ inflammation. Gain-of-function mutations in innate danger-sensing pathways, including the inflammasomes and the nucleic acid sensing pathways, play critical roles in the pathogenesis of IL-1 and Type-I IFN-mediated disorders and point to an important role of excessive proinflammatory cytokine signaling, including interleukin (IL)-1b , Type-I interferons, IL-18, TNF and others in causing the organ specific immune dysregulation. The article discusses the concept of targeting proinflammatory cytokines and their signaling pathways with cytokine blocking treatments that have been life changing for some patients. Read More

Kasposiform hemoangioendothelioma (KHE) and tufted angioma (TA) are classifed as vascular tumors with locally aggressive and benign growth potential, respectively, within the classification schema proposed by the International Society for the Study of Vascular Anomalies. A unique feature of these vascular tumors is the risk of Kasabach-Merritt phenomenon (KMP), a severe thrombocytopenia with mild to moderate coagulopathy resulting from intralesional platelet trapping. As with many vascular anomalies, accurate description of clinical course, responses to therapy, and long-term outcomes have been hindered by lesion misidentification, imprecise nomenclature, and lack of prospective, randomized clinical trials to assess therapeutic efficacy.
