Integration of CT-Based Measurements into Surveillance PET/CT in Patients with Diffuse Large B Cell Lymphoma.

Background: Despite the lack of clinical studies supporting the use of routine surveillance FDG-positron emission tomography (PET) in patients with diffuse large B cell lymphoma (DLBCL) who achieved remission, many centers still use this strategy, especially in high risk patients. Surveillance FDG-PET computed tomography (CT) is associated with a high false positive (FP) rate in DLBCL patients.

Objectives: To investigate whether use of specific CT measurements could improve the positive predictive value (PPV) of surveillance FDG-PET/CT.

Bifocal primary pancreatic Burkitt's lymphoma in a 4-year-old child.

Pancreatic tumors are uncommon in children and rarely result in biliary obstruction. Primary pancreatic Burkitt's lymphoma is an exceptionally rare entity with only a few cases described in the literature. We present a case of a bifocal primary pancreatic Burkitt's lymphoma in a 4-year-old child presenting with jaundice.

Traumatic fracture through the neurocentral synchondroses of L3 vertebra in a 5-year-old child.

Neurocentral synchondroses (NCS) are growth plates that contribute to the transverse growth of the vertebra. Fractures through these NCS are very rare and none have been reported in the lumbar spine. We present a rare case of a traumatic fracture through the neurocentral synchondroses of L3 vertebra in a 5-year-old child.

Purely cystic adrenal lesion in a newborn evolving into a solid neuroblastoma.

Purely cystic neuroblatomas are often discovered prenatally. As the main differential diagnosis is adrenal hemorrhage, follow-up sonography is warranted after birth. Cystic neuroblastomas are expected to evolve into lesions of mixed echogenicity with cystic and solid components.

Bolus guide: a novel insulin bolus dosing decision support tool based on selection of carbohydrate ranges.

Background: Optimal continuous subcutaneous insulin infusion (CSII) therapy emphasizes the relationship between insulin dose and carbohydrate consumption. One widely used tool (bolus calculator) requires the user to enter discrete carbohydrate values; however, many patients might not estimate carbohydrates accurately. This study assessed carbohydrate estimation accuracy in type 1 diabetes CSII users and compared simulated blood glucose (BG) outcomes using the bolus calculator and the "bolus guide," an alternative system based on ranges of carbohydrate load.
