Regional cerebral perfusion was evaluated by single photon emission computed tomography (SPET) using technetium 99m hexamethylpropylene amine oxime (99mTc-HMPAO) as a tracer, in 13 control subjects and 44 age-matched patients suffering from dementia of the Alzheimer's type (DAT, n = 19), presumed Pick's disease (n = 5), idiopathic Parkinson's disease with(More)
We have investigated the dexamethasone suppression of cortisol release in a group of 28 patients with senile dementia of the Alzheimer type (SDAT) after stimulation by physostigmine and clonidine, as compared with basal conditions. All patients but one had previously been evaluated with a depression symptom checklist and had submitted to a standard(More)
in the void volume but preserved the later peak (Fig. 1B). The proCNP concentrations in venous plasma from the controls and from the heart failure patients are shown in Fig. 1C. There was no difference between the 2 groups [median (range), 8.3 (7.0 –12.0) pmol/L vs 8.0 (4.9 –11.0) pmol/L; P ϭ 0.47]. The proCNP concentrations in plasma from different(More)
Night-time melatonin secretion was measured in five depressed inpatients with seasonal affective disorder before and after 1-week of morning and evening exposure to bright (3000 lux) and dim (300 lux) light. Analysis of variance by ranks showed no differences in timing of melatonin secretion but statistically significant differences in plasma melatonin(More)
A decreased thyroid stimulating hormone (TSH) response to thyrotropin releasing hormone (TRH) has been noted in major depression. Some authors found a positive correlation between baseline TSH levels and TSH response to TRH, especially with sensitive assays of TSH. Serum TSH was assayed by a sensitive method in 55 depressed patients and 38 healthy(More)
We report a unusual case of neuralgic amyotrophy (NA) occurring during the seroconversion stage of an HIV infection. Combined with previously published cases, our observation suggests that NA associated with HIV could belong to the group of early multiplex mononeuritis. Neurologists should be aware of HIV infection when managing a patient with NA.
CONTEXT Measurement of IGF-I is essential for diagnosis and management of patients with disorders affecting the somatotropic axis. However, even when IGF-I kit manufacturers follow recent consensus guidelines, different kits can give very different results for a given sample. OBJECTIVES We sought to establish normative data for six IGF-I assay kits based(More)
Eight patients with amyotrophic lateral sclerosis received 500 mg TRH by IV infusion, at a progressive rate during 3 hours. Only 3 patients noted subjective improvement of strength. Clinical muscular testing and H response study failed to show any change. Moreover modifications of the prolactin, growth hormone, TSH and T3 serum levels raise a question(More)
