Neurosyphilis during the AIDS epidemic, San Francisco, 1985-1992.

To investigate the epidemiology and clinical spectrum of neurosyphilis in a population with high rates of coexisting syphilis and human immunodeficiency virus (HIV) infection, a retrospective analysis of cases in all San Francisco hospitals from 1985 to 1992 was conducted. Neurosyphilis was defined by a newly reactive cerebrospinal fluid VDRL; 117 patients with neurosyphilis were identified. The median age was 39 years, 91% were male, 74 (63%) were white, and 75 (64%) were HIV-infected. Thirty-eight (33%) presented with an early symptomatic neurosyphilis syndrome. Six (5%) had late neurosyphilis. Thirty-eight (32%) patients were asymptomatic, and 35 (30%) had findings attributable to coexisting neurologic diseases. Patients demonstrated high serum nontreponemal (VDRL) titers (median, 1:128) at neurosyphilis presentation. In contrast to the findings from the preantibiotic era, neurosyphilis was identified in young patients most often with HIV coinfection, and early symptomatic syndromes were identified more frequently than late neurosyphilis syndromes.

Magnetic resonance spectroscopy of N-acetylaspartate in hypoxic-ischemic encephalopathy.

Magnetic resonance imaging and water-suppressed proton magnetic resonance spectroscopic imaging were used to study N-acetylaspartate and other metabolites in a patient with severe hypoxic-ischemic encephalopathy. The N-acetylaspartate signal, a putative marker of neuronal density, was markedly reduced in the forebrain. The relative signal intensity of choline-containing metabolites, which are more abundant in astrocytes than neurons, was increased. These results support the hypothesis that water-suppressed proton magnetic resonance spectroscopic imaging measurements of N-acetylaspartate may be useful for noninvasive detection of selective neuronal loss in a variety of disease states in the human brain.

Oral amoxicillin in acute uncomplicated gonorrhea.

Of 53 patients with acute uncomplicated gonorrhea treated with amoxicillin 2 g and probenecid 1 g orally as a single administration, six failed to return for follow-up examination, 10 developed postgonococcal urethritis and one was a treatment failure. The remainder achieved symptomatic cure in an average of 2.3 days. Adverse drug effects were infrequent, mild and transient. We conclude that this dose of amoxicillin and probenecid is a safe and effective treatment regimen.

Joan of Arc.

For centuries, romantics have praised and historians and scientists debated the mystery of Joan of Arc's exceptional achievements. How could an uneducated farmer's daughter, raised in harsh isolation in a remote village in medieval France, have found the strength and resolution to alter the course of history? Hypotheses have ranged from miraculous intervention to creative psychopathy. We suggest, based on her own words and the contemporary descriptions of observers, that the source of her visions and convictions was in part ecstatic epileptic auras and that she joins the host of creative religious thinkers suspected or known to have epilepsy, from St. Paul and Mohammed to Dostoevsky, who have changed western civilization.

The promise of birth centres.

The authors argue that birth centres provide quality maternity care to healthy childbearing families at a lower cost than traditional hospital-based obstetrical services. They review the findings of two studies relating to birth centres in British Columbia: a survey of interest in birth centres among women of childbearing age and a survey of providers' opinions about possible features of a birth centre. Forces for and against the implementation of birth centres across Canada are identified.
