OBJECTIVES The purpose of this study was to evaluate the health consequences of employment in the lead-smelting industry. METHODS A mortality study of 1388 workers and laborers in production and maintenance departments was conducted in an Italian lead-smelting plant. The vital status of cohort members was determined from 1950 to 1992. Standardized(More)
Magnetic resonance imaging in 9 cases of surgically confirmed nonneoplastic intra- and/or suprasellar cysts was analyzed and compared with that from 17 cases of craniopharyngioma and 12 of cystic pituitary adenoma. Signal intensity did not help in distinguishing nonneoplastic cysts from cystic neoplasms. No postcontrast (Gd-DTPA) cyst wall enhancement was(More)
PURPOSE Metabolic disturbances are common features of polycystic ovary syndrome (PCOS), which possibly enhance the risk of diabetes and cardiovascular disease. Lipid accumulation product (LAP) is an emerging cardiovascular risk factor. The aim of this study was to explore the ability of LAP to identify metabolic syndrome (MS) in PCOS women. METHODS In a(More)
BACKGROUND Brown adipose tissue (BAT) is important for energy expenditure through thermogenesis, although its regulatory factors are not well known in humans. There is evidence suggesting that thyroid hormones affect BAT functions in some mammals, but the effects of thyroid hormones on BAT activity in humans are still unclear. The aim of this study was to(More)
Primary leiomyosarcoma of the orbit is extremely rare. Here we report the case of a 32-year-old woman who presented with proptosis and diplopia of the left eye. MRI examination showed a solid mass in the left orbit with invasion to adjacent tissue, and the lesion had intense FDG uptake with SUVmax of 18.7 on F-FDG PET/CT. Primary orbit leiomyosarcoma was(More)
Seventeen normal pituitary glands were studied by midline sagittal (and in one case axial) dynamic MRI before and immediately after injection of Gd-DTPA, using spin-echo sequences with a short repetition time. Images were obtained at 1 min intervals for 6 min at 1.5 T. A well-defined focal area with marked enhancement was seen in the posterior portion of(More)
The quantification of neurofibrillary tangles (NFTs) using specific PET tracers can facilitate the diagnosis of Alzheimer's disease (AD) and allow monitoring of disease progression and treatment efficacy. [(18)F]-THK523 has shown high affinity and selectivity for tau pathology. However, its high retention in white matter, which makes simple visual(More)
Primary uterine non-Hodgkin's lymphoma of the cervix is rare. We report a 31-year-old woman presented with menolipsis for 8 weeks. Transvaginal ultrasonography and pelvic MRI detected a solid cervical mass invading the adjacent vaginal wall. The lesion showed obvious FDG uptake on PET/CT scan, and malignancy was considered. It proved to be primary diffuse(More)
Granulomatous slack skin (GSS), a subtype of mycosis fungoides, is an extremely rare disease in cutaneous T-cell lymphoma. Only 1 reported case was documented in the nuclear medicine literature demonstrating this entity with gallium-67. A 16-year-old boy with GSS exhibited moderate F-18 fluorodeoxyglucose uptake in corresponding areas of cutaneous disease(More)
A 43-year-old woman who had a history of right mastectomy for breast cancer presented with fever and swelling in the right supraclavicular region during her second course of chemotherapy. An FDG PET/CT was performed to evaluate this patient, which revealed mildly increased FDG activity in the lymph node in the supraclavicular region. A metastatic lesion(More)
