Calcineurin Inhibitor-Induced Type IV Renal Tubular Acidosis in Post-Bone Marrow Transplant: Review of Pathophysiology and Principles of Management.

Calcineurin inhibitors (CNI) are the mainstay of immunosuppressant medications in both bone marrow transplants and solid organ transplants. Nephrotoxicity is a well-known adverse effect of this group. Type IV renal tubular acidosis is a potentially under-recognized complication.

Impact of the coronavirus disease 2019 (COVID-19) pandemic on pediatric oncology care in the Middle East, North Africa, and West Asia region: A report from the Pediatric Oncology East and Mediterranean (POEM) group.

Background: Childhood cancer is a highly curable disease when timely diagnosis and appropriate therapy are provided. A negative impact of the coronavirus disease 2019 (COVID-19) pandemic on access to care for children with cancer is likely but has not been evaluated.

Methods: A 34-item survey focusing on barriers to pediatric oncology management during the COVID-19 pandemic was distributed to heads of pediatric oncology units within the Pediatric Oncology East and Mediterranean (POEM) collaborative group, from the Middle East, North Africa, and West Asia.

Human Parvovirus B19 in Children with Sickle Cell Disease; Poking the Spleen.

Parvovirus is a known culprit of transient red cell aplasia (TRCA) in children with sickle cell disease (SCD). Few reports have previously described the association between the virus and acute splenic sequestration crisis (ASSC) in the same patient. Here, we are shedding light on such a potentially serious combination by reporting two cases of siblings with SCD complicated with concurrent ASSC and TRCA and presenting a review of the relevant literature.
