Brain mapping studies have shown abnormal changes in cerebral blood volume and oxygen consumption, or other neurophysiological abnormalities, in panic disorder (PD) patients. Because of these intriguing reports, we decided to assess the neuroanatomical aspects of patients with PD using magnetic resonance imaging (MRI). We included 31 consecutive cases with(More)
Thirty consecutive lactate-sensitive panic disorder patients were studied with magnetic resonance imaging (MRI) to investigate the relationship between temporal lobe abnormalities and panic disorder. Neuroanatomical abnormalities, most involving the right temporal lobe, were found in 43% of patients, compared with 10% of the control subjects. Patients with(More)
The 50 patients in this survey were classified by a panel of neurologists into 4 clinical sub-groups: Group Ia ("typical" Friedreich's ataxia, complete picture), Group Ib ("typical" Friedreich's ataxia, incomplete picture), Group IIa ("atypical" Frriedreich's ataxia, possible recessive Roussy-Levy syndrome), Group IIb (heterogeneous ataxias). The clinical(More)
We investigated the effects of a CCK-A receptor antagonist on the development of mother preference. Lambs received 2-NAP either at birth or 6, or 12 h later. Controls were given saline. When tested at 24 h of age, lambs receiving 2-NAP at birth or 6 h later did not display mother preference unlike controls and lambs which were given 2-NAP at 12 h. The(More)
Immune reconstitution inflammatory syndrome (IRIS) occurred in 16 of 37 antiretroviral-naive patients who were treated subsequently for tuberculosis and human immunodeficiency virus (HIV) type 1 infection. IRIS was related to increases in the CD4 cell percentage and in the ratio of CD4 cells to CD8 cells after 1 month of antiretroviral therapy and to(More)
Friedreich's ataxia patients show evidence of an abnormally elevated and prolonged response of pyruvate and lactate to a glucose load, with normal fasting levels. However, ther is a bimodal distribution of this response with high and low pyruvate responders. This trait appears to be determined genetically, However, although in vivo tests suggest low(More)
BACKGROUND Environmentally driven immune activation was suggested to contribute to high rates of HIV-1 infection in Africa. We report here a study of immune activation markers and susceptibility to HIV-1 infection in vitro of forty-five highly exposed uninfected partners (EUs) of HIV-1 infected individuals in Central African Republic, in comparison with(More)
A study of amino acids determined by sequential Multi-sample Amino Acid Automatic Analyzer in plasma, urine and cerebrospinal fluid (CSF) in patients with Friedreich's ataxia and control subjects has revealed a number of mathematically significant variations from normal. Of practical physiological importance are the following: a high urinary excretion of(More)
PURPOSE To locate the origin of the pain during lumbar diskography by means of a limited intradiskal injection of a local anesthetic. METHODS Lumbar diskography by the direct central posterior approach was performed in 235 consecutive patients. In 17 patients, severe and persistent low back pain, with unilateral or bilateral radiation to the lower(More)
Our prospective survey of 50 ataxic patients confirms the previous finding of frequent clinical or chemical diabetes in Friedreich's ataxia. Eighteen percent of our typical cases have clinical diabetes and 40% at least an abnormal glucose tolerance curve. However, this finding does not appear to be specific to that form of ataxia. Furthermore, we have shown(More)
