BACKGROUND: Pompe disease (PD) is an autosomal recessive, lysosomal storage disease due to a mutation of the acid α-glucosidase (GAA) gene. In adult patients, PD is characterized by slowly progressive limb-girdle and trunk myopathy and restrictive respiratory insufficiency. Enzyme replacement therapy (ERT) is available, improving or stabilizing muscle-function in some and slowing deterioration in other patients. Unfortunately, there is no biomarker available to indicate therapeutic efficacy and/or disease activity...

Rosai-Dorfman disease (RDD), or sinus histiocytosis with massive lymphadenopathy, commonly involves the lymph nodes but may secondarily involve the skin. Purely cutaneous disease without lymphatics or internal organ involvement occurs rarely. The present report detailed a rare case of 18F-fluoro-2-deoxyglucose positron emission-computed tomography (18FDG PET-CT) performed in a 33-year-old male soldier with a purely cutaneous form of RDD. Staging with 18FDG PET-CT was ordered prior to excisional biopsies of the aforedescribed masses and pathology reported RDD...

BACKGROUND: The distribution of glucose and fatty-acid transporters in the heart is crucial for energy consecution and myocardial function. In this sense, the glucagon-like peptide-1 (GLP-1) enhancer, sitagliptin, improves glucose homeostasis but it could also trigger direct cardioprotective actions, including regulation of energy substrate utilization. METHODS: Type-II diabetic GK (Goto-Kakizaki), sitagliptin-treated GK (10 mg/kg/day) and wistar rats (n = 10, each) underwent echocardiographic evaluation, and positron emission tomography scanning for [18 F]-2-fluoro-2-deoxy-D-glucose (18 FDG)...

Visualization and metabolic analysis of acute inflammation in the lung parenchyma plays a crucial role for the prediction and diagnosis of radiation-induced lung injury and is particularly important in medically inoperable patients because of a priori very limited pulmonary function. This case confirms that a radiation-induced lung injury is accompanied by acute inflammatory reaction in the lung parenchyma irradiated with a total dose of 12-40 Gy. This well-defined inflammation component could be exactly characterized with FDG-PET/CT...

We audited whether18 F-Fluorodeoxyglucose positron emission tomography-computed tomography (18 FDG PET-CT) imaging could discriminate between different diagnoses in HIV-infected patients presenting with lymphadenopathy, with or without fever and/or splenomegaly. Maximum standardised uptake (SUVmax ) values were similar in lymphoma and mycobacterial and fungal infections and were lower but similar in those with human herpesvirus (HHV) 8-associated disease and HIV-associated reactive lymphadenopathy. Nodal18 FDG avidity, with SUVmax ≥10, excluded diagnoses of HHV 8-associated disease and miscellaneous conditions, and HIV-associated reactive lymphadenopathy was additionally excluded in those who had undetectable plasma HIV viral loads...
