RESUMEN
Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography [PET/CT]imaging with 2-deoxy-2-18F-fluoro-D-glucose [18F-FDG] in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly diagnosed lymphoma, one recurrent lymphoma in previous nerve lesions and one newly recurrent lymphoma. PET/CT could reveal the affected neural structures including cranial nerves, spinal nerve roots, brachial plexus, cervicothoracic ganglion, intercostal nerves, branches of the vagus nerve, lumbosacral plexus and sciatic nerves.There was relative concordance between PET/CT and MRI in detection of affected cranial nerves. PET/CT seemed to be better than MRI in detection of affected peripheral nerves. 18F-FDG PET/CT was a whole-body imaging technique with the ability to reveal the affected cranial nerves, peripheral nerves, nerve roots and plexus in non-Hodgkin lymphoma. A thorough understanding of disease and use of advanced imaging modalities will increasingly detect neurolymphomatosis
RESUMEN
Health status of 1288 employees working at 9 paint, rubber, paper and and processing wood factories where chemicals were used in production in Ha Noi, Hai Phong and Da Nang was investigated. 93.9% of these workers exposure to chemicals. 72.2% to poison gas. 50% of factories had chemical level higher than allowed standards. 83.3% workers had chemical poison signs in 2 months previous. 54.8% had diseases related to using chemical. Rate of workers had been ill in year 2000 in these factories was 34.4%. Among them, 97.3% exposure directly with chemicals. Chemical-related disease prevalence was 89.6%. 44.4% factories did not hold health examination for employees
