Photobiomodulation: a promising innovative approach for preventing oral mucositis in patients undergoing hematopoietic stem cell transplantation.

Purpose: This single-center retrospective study aims to assess the feasibility, safety, and tolerability of CareMin650, a new photobiomodulation device, for both preventing oral mucositis (OM) and reducing its severity in the setting of hematopoietic stem cell transplantation (HCT).

Methods: Patients who underwent autologous HCT for hematological malignancies between November 2020 and October 2021 could be included. Prophylactic photobiomodulation (PBM) was used daily from day 1 of conditioning until the day of neutrophil recovery at a dose of 3 J/cm.

Neutropenic Enterocolitis as a Complication of Autologous Stem Cell Transplant in Patients With Multiple Myeloma: A Case Series.

Neutropenic enterocolitis (NE) is a rare but severe complication occurring in neutropenic patients undergoing intensive chemotherapy. Mortality is high, so early diagnosis is required to start urgent medical or surgical treatment. Data analysis of the development of NE after hematopoietic stem cell transplantation remains scarce.

Kikuchi-Fujimoto's Disease or Histiocytic Necrotizing Lymphadenitis Following mRNA COVID-19 Vaccination: A Rare Case.

Kikuchi-Fujimoto disease (KFD), also known as necrotizing histiocytic lymphadenopathy, is a rare and benign lymph node disorder that mainly occurs in young women. It is clinically characterized by fever with tender and painful cervical lymphadenopathy mostly; however, all areas of lymph nodes can be involved. This disorder is often mistaken for malignant lymphoma or infection.

An Unusual Presentation of Extramedullary Relapse Following Blinatumomab in Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia.

In adult patients, extramedullary relapse (EMR) in B-acute lymphoblastic leukemia (B-ALL) has a pejorative prognosis, especially after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Blinatumomab, a bispecific CD3/CD19 antibody, is approved for relapsed/refractory acute lymphoblastic leukemia (ALL) and has proven its efficacy with good complete response (CR) rates and molecular responses in several trials. Unusual sites of relapse following treatment with blinatumomab for ALL are rarely reported.
