Review Comparative StudyPercutaneous vertebral augmentation: vertebroplasty, kyphoplasty and skyphoplasty.
Percutaneous vertebroplasty is a safe, inexpensive, and effective interventional vertebral augmentation technique that provides pain relief and stabilization in carefully selected patients with severe back pain due to vertebral compression. Complications from percutaneous vertebroplasty can be devastating, but are rare and avoidable with application of a meticulous technique. ⋯ Kyphoplasty is as effective and safe as vertebroplasty in treatment of painful vertebral compression fractures. Skyphoplasty, a modification of kyphoplasty, is a promising new technique.

ReviewFluorine-18 fluorodeoxyglucose PET/CT patterns of extranodal involvement in patients with Non-Hodgkin lymphoma and Hodgkin's disease.
Lymphoma may originate in extranodal sites. Extranodal lymphoma may also be secondary to and accompany nodal disease. ⋯ Accurate staging and localization often dictate the appropriate treatment strategy in patients with lymphoma. Therefore, at any stage in the course of the disease, the potential presence of extranodal disease should be considered when interpreting 18F-FDG PET/CT studies in patients with non-Hodgkin lymphoma and Hodgkin's disease.
