BACKGROUND AND PURPOSE Functional neuroimaging studies have demonstrated right inferior frontal gyrus (IFG) activation in poststroke aphasia. It remains unclear whether this activation is essential for language performance. We tested this hypothesis in a positron emission tomography (PET) activation study during a semantic task with repetitive transcranial(More)
BACKGROUND AND PURPOSE Recently, a combined repetitive transcranial magnetic stimulation (rTMS) and activation positron emission tomography (PET) study showed essential language function of the right inferior frontal gyrus (IFG) in some right-handed acute poststroke aphasics. We reexamined these patients in the chronic phase to test whether the right IFG(More)
Neuroimaging studies in right-handed patients with left hemisphere brain lesions have demonstrated a shift of language activity from left to right inferior frontal gyrus (IFG). This shift may be caused by greater right hemisphere dominance before the injury or by reduced inhibitory activity of the injured left hemisphere. We simulated a brain lesion(More)
A 30-year-old woman had an acute inferior wall myocardial infarction at 21 weeks' gestation and was successfully treated with intravenous tissue plasminogen activator. This case demonstrates that good perinatal outcome is possible after thrombolytic therapy for acute myocardial infarction complicating the second trimester of pregnancy.
High resolution positron emission tomography (PET) with the newly developed HRRT scanner (Siemens/CTI) permits the reliable quantification of 18-Fluorodeoxyglucose (FDG) uptake as a marker of neuronal activity in small subcortical nuclei which are involved in the pathophysiology of Parkinson's disease (PD). We investigated the normalized cerebral metabolic(More)
618 women aged 13-36 attending a family planning clinic took part in a sexual health survey during 1985 and 1986. They were followed up for one year in order to ascertain whether an increase in atypical and dysplastic pap smears was linked to a certain lifestyle. The routine examination included a pap smear, a cervical swab for gonorrhea and other vaginal(More)
A case report is given of a 61 year old female patient, who came to the hospital with chronic pain in the right upper abdominal quadrant, fever, chills, dyspnea, and general weakness. 4 days later she died in hemorrhagic shock after having had melena. At postmortem an actinomycotic abscess of the size of a childs head was found in the left lobe of the(More)
