The lack of a method for demonstrating the presence of Treponema pallidum by growth necessitates the use of alternative methods. Traditionally, these methods are divided into direct detection methods (animal inoculation, dark-field microscopy, etc.) and serologic tests for the presence of patient antibody against T. pallidum. Serologic methods are further(More)
BACKGROUND Hypothalamo-pituitary-adrenal (HPA) function has been demonstrated to be compromised for weeks and even months after alcoholics cease ethanol consumption. Because nonalcoholic subjects with family history-associated increased risk for alcoholism also exhibit compromised HPA function, it is not clear whether defects in the HPA axis of abstinent(More)
BACKGROUND Reports of neurosyphilis and invasion of cerebrospinal fluid by Treponema pallidum in patients with human immunodeficiency virus (HIV) infection have led to doubts about the adequacy of the recommended penicillin G benzathine therapy for early syphilis. METHODS In a multicenter, randomized, double-blind trial, we assessed two treatments for(More)
Reports of Lyme disease from areas where the disease is not endemic have increased. Eighty-six human serum samples from Papua New Guinea (nonendemic for Lyme disease) were examined for the presence of IgG antibodies that recognize Borrelia burgdorferi antigens, using the currently recommended two-tiered system of analysis (sensitive ELISA with Western(More)
The Centers for Disease Control conducted a case-control study to investigate an outbreak of Kaposi's sarcoma and Pneumocystis carinii pneumonia in homosexual men. The occurrence of these diseases was found to be associated with certain aspects of lifestyle, including a greater number of male sex partners per year, exposure to feces during sex, history of(More)
Sera were obtained from 266 mothers of singleton stillborn babies (cases) and 266 mothers of live-born babies (controls), matched for parity, who delivered at the University Teaching Hospital, Lusaka, Zambia, between October 1979 and April 1980. Tests were performed on 262 samples from cases and 261 from controls. The microhaemagglutination assay for(More)
One important aspect of the posttreatment evaluation of patients with early syphilis is assessment of serological test results. Using information previously collected from 818 patients in the Early Syphilis Study, we evaluated the seroresponse of people treated for primary or secondary syphilis. We generated curves describing the VDRL titer declines with(More)
To evaluate the sensitivity of treponemal tests as a marker of prior syphilis in individuals with human immunodeficiency virus (HIV) infection, the syphilis serology of 109 homosexual men with a documented history of treated syphilis was compared with records of prior results and confirmed on stored serum samples. None of the HIV-seronegative individuals(More)
Pineal melatonin secretion has been reported to commonly decrease with aging, whereas intra-abdominal adiposity, plasma insulin and plasma leptin levels tend to increase. We recently demonstrated that daily melatonin administration starting at middle age suppressed male rat intra-abdominal fat, plasma leptin and plasma insulin to youthful levels, suggesting(More)
The annual numbers of reported cases of syphilis in the Republic of the Marshall Islands (RMI) increased from none in 1983 to more than 600 in 1989, suggesting a large outbreak of syphilis. Much of the increase resulted from expanded serological screening. The apparent outbreak of syphilis, therefore, may have been partly the result of increased(More)
