🩸🩸Evolution of the use of Therapeutic Fibrinogen Concentrate in the Massive Bleeding Guidelines🩸🩸

🩸En pacientes con politraumatismo con hemorragia grave, se recomienda la administración de fibrinógeno en función de criterios clínicos y antes de los resultados de las pruebas de laboratorio.
🩸🩸Después de este primer enfoque, las directrices recomiendan el manejo de la coagulación dirigido a objetivos basado en los resultados de las pruebas viscoelásticas y, en su ausencia, se recomiendan las pruebas de laboratorio clásicas.🩸

𝗩𝗗𝗝 𝗿𝗲𝗰𝗼𝗺𝗯𝗶𝗻𝗮𝘁𝗶𝗼𝗻 is a process involving the cutting and rejoining of the loci encoding T-cell and B-cell receptors. These loci are highly polymorphic and contain multiple variable (V), diversity (D), and joining (J) regions, flanked by recombination signal sequences (RSS). Each developing T and B cell rearranges the locus to generate a unique transcript containing one V, one D, and one J region, a process known as VDJ recombination. The RAG1–RAG2 protein complex begins this process by cutting at RSS sites. More about this NEJM Illustrated Glossary term in comments.

An unusual presentation of systemic mastocytosis in a myelolipoma

A 51-year-old man with a history of anaphylactic reaction to hornet venom presented with abdominal pain, melena, and bowel habit changes. No skin lesions or hepatosplenomegaly were identified. Positron emission and computed tomography revealed a retroperitoneal fat-containing mass in the left lower abdominal quadrant, measuring 5.7 cm in its greatest dimension (panel A-B, arrow). A needle-core biopsy of the mass showed hematopoietic elements (panel C: hematoxylin and eosin stain, 50× objective) with a small aggregate of elongated cells associated with eosinophils (panel D, 50× objective). The cells were positive for mast cell tryptase, CD117, and CD25 (panels E-F, 20× and 50× objectives, respectively). The findings were compatible with myelolipoma and an abnormal mast cell aggregate suspicious for mastocytosis. Complete blood cell count was normal. Subsequent bone marrow biopsy showed abnormal CD25+ mast cell aggregates, comprising 5% of the cellularity. There was no evidence of dysplasia or increased blasts. Cytogenetics showed a normal male karyotype 46,XY[19]. Myeloid next-generation sequencing was negative for pathogenic variants in myelodysplastic syndrome–associated genes. The tryptase level was 23.6 ng/mL (reference value,
