As outcomes have improved across the hematologic malignancy population, candidacy for ICU admission has increased. This complex population may develop a variety of complications related to their treatment or underlying disease that can result in critical illness necessitating ICU support. This review highlights common causes of critical illness associated with hematologic malignancies, including the following: (1) neutropenic sepsis; (2) hyperleukocytosis and leukostasis across patients with acute myeloid leukemia; (3) complications of acute promyelocytic leukemia; (4) tumor lysis syndrome; and (5) critical care complications that can arise following hematopoietic stem cell transplantation.

The flow of cerebrospinal fluid (CSF) has been described as a unidirectional system with the choroid plexus serving as the primary secretor of CSF and the arachnoid granulations as primary reabsorption site. This theory of neurosurgical forefathers has been universally adopted and taught as dogma. Many neuroscientists have found difficulty reconciling this theory with common pathologies, and recent studies have found that this "classic" hypothesis may not represent the full picture. ⋯ We have highlighted major studies to illustrate modern principles of CSF dynamics. Despite these, the medical education system has been slow to reform curricula and update learning resources.

To describe expected endoscopic and histological changes at gastro-esophageal junction (GEJ) and define diagnostic paradigms for Barrett esophagus (BE) postsleeve gastrectomy (SG). ⋯ A novel appearance of tubularized cardia telescoping supra-diaphragmatically with flattening of gastric folds is common post SG, likely associated with isobaric hyper-pressurization of proximal stomach. incidence of true BE post SG is low in short-intermediate term. These provided a clear framework for approaching endoscopic screening and surveillance, with correct anatomical and mucosal identifications, and clarified key issues of SG and BE.
