Meningitis as the initial manifestation of systemic lupus erythematosus.

Systemic Lupus Erythematosus (SLE) is an idiopathic chronic autoimmune disease that can affect multiple organs including the Central Nervous System (CNS). CNS involvement is seen in many SLE patients; however, usually it is preceded by/or in conjunction with other organ-system involvement. The spectrum of CNS involvement is wide and includes numerous neuro-psychiatric syndromes but rarely meningitis.

Effectiveness of prolonged fasting 18f-FDG PET-CT in the detection of cardiac sarcoidosis.

Background: The Japanese Ministry of Health and Welfare guidelines (JMHWG) are currently the standard used to diagnose cardiac sarcoidosis. JMHWG incorporate (67)Gallium scintigraphy as a minor criterion, while fasting (18)fluorine-2-fluoro-2-deoxy-D-glucose (FDG) PET is not included. As there is no published data comparing the accuracy of prolonged fasting FDG PET-CT (PF-PET) and Gallium scintigraphy for detecting active cardiac sarcoidosis, we sought to compare these two modalities.
