The purpose of the present study was to evaluate neuropsychological performance and regional cerebral blood flow in migraine patients, and to investigate whether possible abnormalities in any of these fields could be related to the chronicity of the disease. The sample included 60 patients and 30 healthy control subjects; all of them were subjected to a complete neuropsychological assessment, i...
BACKGROUND AND OBJECTIVE In a security ward we assessed the diagnostic contribution of single photon scintigraphy [SPECT] in our diagnostic pathway for patients with serious mental disease and a history of violence. METHODS Twenty patients were examined between 2012 and 2015 and the findings compared to those in nine patients with the same diagnosis, but no history of violence. RESULTS All ...
BACKGROUND Hereditary Coproporphyria (HCP) is characterized by abdominal pain, neurologic symptoms and psychiatric disorders, even if it might remain asymptomatic. The pathophysiology of both neurologic and psychiatric symptoms is not fully understood. Therefore, aiming to evaluate a possible role of brain blood flow disorders, we have retrospectively investigated cerebral perfusion patterns in...
OBJECTIVE The purpose of this study was to investigate if an octadecyl (18C) minicolumn could be applied successfully for quality control of 99mTc exametazime (HMPAO). METHODS The 18C column system using saline eluent was validated against the Whatman 17 method in calculating the percent radiochemical purity of 99mTc-HMPAO. The behavior of 99mTc-pertechnetate (99mTc04-) and hydrolyzed-reduced...
The purpose of this study is to determine the value of Tc-99m HMPAO SPECT in the diagnosis of the dementias. Tc-99m HMPAO was used with a 3-camera scanner to produce 5 sets of sectional images of the brain. Images were further processed using Statistical Parametric Mapping. Diagnosis was made by a physician blinded to the clinical diagnosis. Results in 73 subjects were compared with a neuropath...
OBJECTIVE To compare the HMPAO SPECT cerebral perfusion patterns in early and late onset Alzheimer's disease. METHODS Twenty patients with early onset disease (<65 years) and 44 patients with late onset disease (>65 years) were studied. All patients fulfilled NINCDS-ADRDA clinical criteria and had details of disease severity and length of history at the time of imaging. Technetium-99m HMPAO S...
1515 OBSTRUCTIVE SLEEP APNEA-HYPOPNEA SYNDROME (OSAHS) IS CHARACTERIZED BY REPEATED EPISODES OF UPPER AIRWAY OBSTRUCTION DURING SLEEP, with disturbances in arterial blood gases and increasing inspiratory effort until the upper airway obstruction discontinues due to arousal. OSAHS has a relatively high prevalence and occurs in 5% of the adult population.1 OSAHS may cause daytime sleepiness, redu...
