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)
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)
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)
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 forty-four(More)
Three patients with portal venous gas (one with radiographic and computed tomographic findings) had similar sonographic and Doppler patterns in the portal vein (PV). These patterns consisted of hyperechogenic foci moving within the lumen of the PV, producing sharp bidirectional spikes superimposed on the usual Doppler tracing of the PV. An injection of(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)
A prospective sonographic analysis of kidneys in 136 adults without clinical or radiologic evidence of renal disease revealed 22 cases of large columns of Bertin. Most were located in the middle third of the kidney, more frequently on the left side. They were bilateral in 18%. Water bath sonograms of normal cadaver kidneys and subsequent anatomic(More)
BACKGROUND Since the introduction of laparoscopic adrenalectomy there has been major concern about proper indications for its use, including in pheochromocytoma. In this study we reviewed pheochromocytomas resected by means of laparoscopy to establish that procedure's usefulness. METHODS Between January 1992 and June 1995, 90 laparoscopic adrenalectomies(More)
STUDY DESIGN Independent evaluation by two observers of 132 lumbar discs in 45 patients with chronic low back pain investigated by both magnetic resonance imaging and discography. OBJECTIVES To assess some of the fundamental differences between lumbar disc protrusions, disc bulges, and discs with normal contour but abnormal signal intensity on T2-weighted(More)
The authors developed a simplified description of the segmental anatomy of the liver on the basis of the Couinaud nomenclature. This approach was demonstrated with normal in vivo sonographic images and livers dissected in corresponding planes. The branches of the portal vein, which lead to the center of individual segments, are used as key landmarks in the(More)
