Blood transfusion in children at a university hospital in a middle-income country: The need to reinforce adherence to current guidelines.

Objectives: Blood component transfusion is a common procedure used during hospital admissions; however, it is not risk-free. The evaluation of correct use of blood products (BP) is of vast importance considering the risks and costs implied in their use. Our principal objective was to evaluate the adherence to national guidelines for blood transfusion in pediatric patients at a third level university hospital.

Gastric Metastasis of Prostate Cancer as an Unusual Presentation Using 68Ga-Prostate-Specific Membrane Antigen PET/CT.

A 79-year-old man with prostate cancer underwent Ga prostate-specific membrane antigen (Ga-PSMA) dual-time-point PET/CT scan to evaluate tumor activity due to early satiety, unquantified weight loss, and elevation of prostate-specific antigen (PSA), demonstrating thickening of the gastric wall with intense tracer uptake. The immunohistochemistry of gastric biopsy showed CDX2 and CK20: negative; CK7, focal positive; PSA, positive, which confirmed metastatic disease. Metastatic disease was also found in bones, right lung, and retroperitoneal and pelvic lymphadenopathies.
