intraspecific phylogenetics: support for dental transmission of human immunodeficiency virus.	a new method to estimate within-species gene genealogies was used to establish linkages among individuals associated with the florida dental human immunodeficiency virus transmission case. phylogenetic relationships were estimated from 103 nucleotide sequences from the v3 region of the env gene representing the florida dentist, eight of his seropositive patients, and many local controls. the cladogram estimation procedure supports linkages among individuals within the previously described dental ...	1995	7884881
complex role of gamma-herpesviruses in multiple sclerosis and infectious mononucleosis.	various researchers over the past few years have demonstrated higher titers and higher incidence rates of epstein-barr virus (ebv) antibodies in multiple sclerosis (ms) patients compared to controls. these findings were tentatively attributed to immunoregulation abnormalities of ms or perhaps to some other relationship with the ms syndrome yet to be determined. meanwhile, an intensive environmental investigation of the key west cluster just before it ended and for two years afterwards produced t ...	1993	7907407
a role for molecular genetics in biological conservation.	the recognition of recent accelerated depletion of species as a consequence of human industrial development has spawned a wide interest in identifying threats to endangered species. in addition to ecological and demographic perils, it has become clear that small populations that narrowly survive demographic contraction may undergo close inbreeding, genetic drift, and loss of overall genomic variation due to allelic loss or reduction to homozygosity. i review here the consequences of such genetic ...	1994	7912434
human rabies--miami, 1994.	a high proportion of recent human rabies cases diagnosed in the united states have been acquired outside the country and have lacked a history of animal bite exposure. on june 21, 1994, a 40-year-old man died in a hospital in miami following a subacute and progressive neurologic syndrome; rabies had not been clinically suspected but was diagnosed postmortem on july 13. this report summarizes the case investigation, which indicated that the case was acquired outside the united states.	1994	7935313

aids epidemic among florida women.	impact of the human immunodeficiency virus among women in florida is increasingly recognized in the second decade of the aids epidemic. illicit drug use, sexual activity with multiple partners, lack of access to health care, and socioeconomic disadvantages are greatly contributing to the increase of female aids cases. current salient features of the epidemic are summarized as well as prevention strategies to reduce transmission of the virus.	1993	8505615
surveillance of tuberculosis and aids co-morbidity--florida, 1981-1993.	because immunosuppression induced by human immunodeficiency virus (hiv) infection increases the likelihood that latent tuberculosis (tb) infection will become active in hiv-infected persons (1,2), in 1987, extrapulmonary or disseminated tb was added to the acquired immunodeficiency syndrome (aids) surveillance case definition (3), and in 1993, pulmonary tb in hiv-infected persons was added to the case definition (4). in florida and other areas (5), aids surveillance activities include assessment ...	1996	8531919
the 1990 florida dental investigation: is the case really closed?	in 1994, a magazine article, a newspaper article, and a segment of the television newsmagazine 60 minutes presented information that cast doubt on the centers for disease control and prevention's conclusion that a dentist in florida had infected six of his patients with the human immunodeficiency virus (hiv). these reports were based on previously unavailable documentary evidence, which suggested that the infected patients had unreported or undetected risk factors for hiv infection and that the ...	1996	8534001
the 1990 florida dental investigation: theory and fact.	controversy remains about the centers for disease control and prevention's (cdc) conclusion that a dentist in florida transmitted human immunodeficiency virus to six of his patients in the late 1980s. the most vocal doubt has come from journalists affiliated with the television program 60 minutes. although unanswered questions about the case remain, the evidence continues to overwhelmingly support the cdc's theory. the criticism of the cdc investigation consists largely of assertions that contra ...	1996	8534002
hantavirus pulmonary syndrome in florida: association with the newly identified black creek canal virus.	hantavirus pulmonary syndrome (hps) is a recently recognized viral zoonosis. the first recognized cases were caused by a newly described hantavirus. sin nombre virus (previously known as muerto canyon virus), isolated from peromyscus maniculatus (deer mouse). we describe a 33-year-old floridian man who resided outside the ecologic range of p maniculatus but was found to have serologic evidence of a hantavirus infection during evaluation of azotemia associated with adult respiratory distress synd ...	1996	8579086
infections in children with human immunodeficiency virus/acquired immunodeficiency syndrome: an autopsy study of 30 cases in south florida, 1990-1993.	thirty autopsies performed on infants and children with hiv infection and/or aids were reviewed for the presence and type of infection. twenty-six (87%) demonstrated evidence of infection in addition to hiv at the time of postmortem examination. pathogenic bacterial infectious were the most frequently encountered, seen in 15 of the cases. nine of the 15 (60%) were due to gram-negative rods, most commonly pseudomonas aeruginosa. infections with gram-negative organisms often involved multiple orga ...	1995	8597814
human immunodeficiency virus-infected health care workers: the restoration of professional authority.	during the first years of the human immunodeficiency virus (hiv) epidemic, the professional limitation on hiv-infected physicians and other health care workers were left to the discretion of the infected workers themselves and the medical institutions in which they worked. in the crisis occasioned by the report of iatrogenic infection in a florida dental practice, the legal system was expected to develop mandatory standards for the management of an estimated 50 000 american health care workers w ...	1996	8601206
detection of hiv-1 dna in needle/syringes, paraphernalia, and washes from shooting galleries in miami: a preliminary laboratory report.	shared use of injection equipment (needle/syringes), registering, booting, and backloading are practices among injection drug users (idus) that increase the risk for transmission of human immunodeficiency virus type 1 (hiv-1). the sharing of injection paraphernalia (including cookers and cottons) and washwater for rinsing used needle/syringes and dissolving drugs could be potential sources for secondary transmission of hiv-1. laboratory rinses were made from needle/syringes, cottons, and cookers ...	1996	8603266

[tuberculosis and the hiv pandemic. risk of nosocomial tuberculosis infection].	spread of human immunodeficiency virus (hiv) infection has had a major impact on the epidemiology of tuberculosis. in several african countries the incidence of tuberculosis has doubled, and the prevalence of hiv infection among patients with tuberculosis is 20 to 60%. a similar change has occurred in some developed countries. several factors, including hiv infection, have contributed to this change. tuberculosis among hiv infected patients is probably more often a result of a new infection with ...	1997	9072866
polymerase chain reaction testing for early detection of hiv infection in children.	diagnosis of vertically acquired human immunodeficiency virus (hiv) infection is often difficult because of transplacentally acquired maternal antibodies. the polymerase chain reaction (pcr) test is commercially available and has high sensitivity and specificity. to evaluate the usefulness of pcr testing in the early diagnosis of perinatally acquired hiv infection, we reviewed records of 122 children having follow-up in the northeast florida pediatric aids program. seventy-two children were excl ...	1997	9076299
