Abstract
The management of hyperleukocytosis or thrombocytosis by therapeutic cytapheresis in the early 21 st century is far from codified (universal). Therapeutic cytapheresis have been proposed to achieve more rapid cytoreduction in peripheral blood than old universal support in order to quickly prevent potential complications. But, there are no randomized studies demonstrating the superiority of cytapheresis over other treatments alone. In this short review, based on our own experience (since 1980), we will give the indications and the role of cytapheresis procedures and we will try to answer the questions: when is therapeutic cytapheresis appropriate and do they still have a place in 2020, especially as a medical emergency?

Abstract
The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating and categorizing indications for the evidence-based use of therapeutic apheresis (TA) in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Eighth Edition of the JCA Special Issue continues to maintain this methodology and rigor in order to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Eighth Edition, like its predecessor, continues to apply the category and grading system definitions in fact sheets. The general layout and concept of a fact sheet that was introduced in the Fourth Edition, has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of TA in a specific disease entity or medical condition. The Eighth Edition comprises 84 fact sheets for relevant diseases and medical conditions, with 157 graded and categorized indications and/or TA modalities. The Eighth Edition of the JCA Special Issue seeks to continue to serve as a key resource that guides the utilization of TA in the treatment of human disease.

Abstract
Therapeutic plasma exchange (TPE) has been used as a treatment modality in many autoimmune disorders, including neurological conditions, such as Guillain-Barre syndrome (GBS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). The American Society for Apheresis (ASFA) publishes its guidelines on the use of therapeutic apheresis every 3 years based on published evidence to assist physicians with both the medical and technical aspects of apheresis consults. The ASFA Guidelines included the use of TPE in both GBS and CIDP as an acceptable first-line therapy, either alone and/or in conjunction with other therapeutic modalities. In this article, we briefly reviewed GBS and CIDP, discussed the role of apheresis in these conditions as well as various technical aspects of the TPE procedure, such as apheresis calculation, number of volume exchange, replacement fluid, and management of potential complications.

Abstract
Oncologic emergencies may be seen in any emergency department and will become more frequent as our population ages and more patients receive chemotherapy. Life-saving interventions are available for certain oncologic emergencies if the diagnosis is made in a timely fashion. In this article we will cover neutropenic fever, tumor lysis syndrome, hypercalcemia of malignancy, and hyperviscosity syndrome. After reading this article the reader should be much more confident in the diagnosis, evaluation, and management of these oncologic emergencies.

Abstract
BACKGROUND Chronic myeloid leukemia (CML) is a common hematologic malignancy; however, its occurrence during pregnancy is unusual due to its low prevalence in females of childbearing age. There are conflicting reports of how to best manage CML in pregnancy, particularly in the setting of leukocytosis. HEMAPHERESIS A 30-year-old female was diagnosed with CML at 18 weeks' estimated gestational age. On initial presentation she reported fatigue, night sweats, and early satiety, and was found to have a white blood cell (WBC) count of 69.3 × 109 /L and platelet count of 366 × 109 /L. Her disease was managed during pregnancy using interferon-α alone despite persistent leukocytosis. CONCLUSION CML may be effectively managed during pregnancy, even in the setting of leukocytosis, without the application of leukocytapheresis. Management relies not only upon the coordination of drug therapy and fetal monitoring, but requires close communication between multiple medical disciplines. Leukocytapheresis has been safely performed during pregnancy and may be a suitable adjunct management strategy in pregnant patients diagnosed with CML with specific clinical presentations, such as hyperleukocytosis (WBC count > 150 × 109 /L) and/or symptomatic leukostasis.

Abstract
INTRODUCTION Hyperleukocytosis (HL) and leukostasis seen in myeloid leukemias are a medical emergency. We present a case series of ten such patients in a 4-year period. Sixteen therapeutic leukocyte reduction (TLR) were done in ten cases along with other supportive measures. The American Society for Apheresis supports the routine implementation of TLR in cases of HL secondary to myeloid leukemias with signs of leukostasis. MATERIALS AND METHODS The procedures were performed on the intermittent flow cell separator after discussion with the treating physician about patient's condition. Clinical, demographic, analytical, and technical variables were reviewed retrospectively and the patients were followed up at the end of 4 years. Descriptive analysis was performed for all variables, and relationships between quantitative variables and categorical variables were determined by applying the Student's t-test. RESULTS The mean age of presentation was 34 years. Priapism was the most common symptom followed by respiratory distress and neurological disturbances. After an average of 1.6 TLR procedures, the mean leukocyte count reduction achieved was 39.9% along with symptomatic relief. The mean survival at 4-year follow-up was 12.8 months and the overall mortality was 20%. Acute myeloid leukemia patients presented with lower mean platelet counts compared to chronic myeloid leukemia patients; however, the platelet loss in the final product was minimized. CONCLUSION TLR is a safe and effective therapy for leukoreduction in hematological malignancies in our experience.

Abstract
The development of medical emergencies related to the underlying disease or as a result of complications of therapy are common in patients with hematologic or solid tumors. These oncological emergencies can occur as an initial presentation or in a patient with an established diagnosis and are encountered in all medical care settings, ranging from primary care to the emergency department and various subspecialty environments. Therefore, it is critically important that all physicians have a working knowledge of the potential oncological emergencies that may present in their practice and how to provide the most effective care without delay. This article reviews the most common oncological emergencies and provides practical guidance for initial management of these patients.

Abstract
BACKGROUND Many practitioners believe in the phenomenon of either being labeled a "black cloud" or "white cloud" while on-call. A "white-cloud" physician is one who usually gets fewer cases. A "black-cloud" is one who often has more cases. It is unclear if the designation is only superstitious or if there is some merit. Our aim is to objectively assess this phenomenon in apheresis medicine at our center. METHODS A one-year prospective study from 12/2014 to 11/2015 was designed to evaluate the number of times apheresis physicians and nurses were involved with emergent apheresis procedures between the hours from 10 PM and 7 AM. Other parameters collected include the names of the physician, apheresis nurse, type of emergent apheresis procedure, day of the week, and season of the year. RESULTS During the study period, 32 emergent procedures (or "black-cloud" events) occurred. The median time between two consecutive events was 8 days (range: 1-34 days). We found no statistically significant association between the "black-cloud" events and attending physicians, nurses, day of the week, or season of the year by Chi-square and Fisher's analyses. However, exploratory analysis using association rule demonstrated that "black-cloud" events were more likely to happen on Thursday (2.19 times), with attending physician 2 (1.18 times), and during winter (1.15 times). CONCLUSION The results of this pilot study may support the common perception that some physicians or nurses are either "black cloud" or "white cloud". A larger, multi-center study population is needed to validate the results of this pilot study.
