Título: Segregation of human T cell lymphotropic virus type I and II infections by antibody reactivity to unique viral epitopes
Fonte: J Infect Dis;165(2):268-72, Feb. 1992.
Idioma: En.
Resumo: A recombinant protein of the human T cell lymphotropic virus type I (HTLV-I) gp46 outer membrane envelope, MTA-4 (residues 129-203), reacted by Western blot with sera from HTLV-I-infected individuals from the United States and Jamaica but not with 24 (10 percent) of 242 Japanese sera. A related gp46 recombinant protein, MTA-1 (residues 162-209), reacted with all 58 sera from HTLV-I-infected US and Jamaican individuals and 238 of 242 sera from infected Japanese (combined sensitivity of 99 percent). Neither recombinant showed reactivity to sera from HTLV-II-infected individuals or uninfected controls. The reactivity of recombinant proteins containing the region of HTLV-II gp46 analogous to MTA-1 was also evaluated by Western blot: GH2-K15 (residues 157-205) and GH2-K55 (residues 162-205) reacted with 88 (98 percent) and 89 (99 percent), respectively, of 90 sera from HTLV-II-infected individuals but not with sera from HTLV-I-infected individuals or uninfected controls. These recombinant proteins should permit the development of assays to unambiguously confirm and differentiate HTLV-I and HTLV-II infections. (AU)

Título: Human T-lymphotropic virus type 1: a retrovirus causing chronic myeloneuropathies in tropical and temperate climates
Fonte: Am J Hum Biol;2:429-38, 1990.
Idioma: En.
Resumo: Human T-cell lymphotropic virus type I (HTLV-I), the first human retrovirus to be isolated, is the cause of endemic tropical spastic paraparesis (TSP). Originally, this chronic neurological disorder was described as a disease seen among blacks of low socioeconomic status living in tropical countries, and thus for many decades TSP remained a little known curiousty outside the endemic regions. The link between HTLV-I infection and TSP was made fortuitously, when antibodies to HTLV-I were found in serum and cerebrospinal fluid of TSP patients in Jamaica, Colombia, and Martinique. Soon thereafter a similar disorder, designated HTLV-I associated myelopathy (HAM), was reported from southern Japan. This broadened the geographic and ethnic boundaries of this chronic myelopathy and the disease has now been reported in multiple ethnic groups from more than 40 countries, in both tropical and temperate regions. The name TSP/HAM is now used to include all patients (regardless of race or country of origin) who have HTLV-I-positive endemic TSP or HAM. (AU)

Título: Geographic differences in the severity of aortic and coronary atherosclerosis
Fonte: Am J Pathol;36(5):559-74, May 1960.
Idioma: En.
Resumo: Comparison of aortic and coronary atherosclerosis in the United States, Jamaica, Japan and India demonstrates that after the first two decades of life, there is a greater severity of intimal alteration in the United States than in the other population groups. The 3 foreign populations exhibited much less coronary atherosclerosis and a lower incidence of myocardial infarction. Their diets, too, were of lower caloric content and contained less than half the fat found in the United States diet. In Japan and Jamaica, atherosclerosis proved to be disproportionately more severe in the aorta than in the coronary arteries. Accordingly, appraisals of atherosclerosis limited to the aorta do no provide adequate indexes of geographical variations. A much lower proportion of complicated atheromatous lesions (ulcerated or calcified plaques) accounted for most of the differences observed. While there was a general parallelism between the severity of coronary atherosclerosis and the frequency of myocardial infarction, there were instances of cardiac infarction associated with relatively minor degrees of coronary intimal alteration. These situations indicate that virtually all grossly recognizable intimal lesions may be complicated by thrombosis (Summary)

Título: WHO collaborative study on the sero-epidemiology of rubella
Fonte: Bull World Health Organ;37(1):79-88, 1967.
Idioma: En.
Resumo: Under the auspices of WHO an investigation was made by 9 laboratories in different parts of the world on the distribution of rubella antibodies in girls and women of child-bearing age. In the first part of the study the objective was to determine the reliability and reproducibility of the tests employed. It was found that there was no significant differences in the variability of the titres obtained by repeatedly testing the same sera in one laboratory. In the second part of the study sera were obtained from girls in schools and women attending clinics and health centres. They were not taken from random samples of the populations. In most of the studies the pattern of development of antibody was similar. About half the persons had antibody at 6-8 years of age and 80 percent-87 percent at 17-22 years of age, the percentage remaining relatively constant thereafter. The island populations of Trinidad and Jamaica and a rural area of Japan were, however, found to have significantly fewer women with antibodies than urban areas in Europe or the Americas.(AU)

Título: Idiopathic cardiomegaly
Fonte: Bull World Health Organ;38(6):979-92, 1968.
Idioma: En.
Resumo: Cardiomyopathies are certain heart diseases of unknown etiology and pathogenesis, occurring mostly in tropical and subtropical areas, where they constitute a major clinical problem and sometimes a public health problem. The need for international co-operation in the study of such forms of heart diseases has long been recognized and WHO convened informal meetings of investigators on various aspects of the subject in 1964, 1965 and 1966. Out of these have arisen co-operative studies co-ordinated by WHO. In November 1967 a fourth informal meeting was held in Kingston, Jamaica, to review the following topics: the progress reports from all co-operating laboratories; the diferent types of cardiomyopathies; past experience with cardiac registries, and the diagnostic importance of coronary angiography. Steps were taken towards the formulation of a standard terminology, since too many confusing names are currently employed to mean "cardiomegaly of unknown origin". A common name, "idiopathic cardiomegaly", was therefore suggested for further use. The account presented here was prepared by Dr. Z. Fejfar, Chief Medical Officer, Cardiovascular Diseases, World Health Organization, Geneva, on behalf of the other participants and is a precis of some of the information that was exchanged, some of the views that were expressed and of the suggestions that were made.(AU)

Título: Carcinoma of the female breast in Jamaica
Fonte: Trop Geogr Med;29(3):213-22, Sept. 1977.
Idioma: En.
Resumo: The incidence of breast cancer in Jamaican women is intermediate between the low levels of African countries and the high levels of USA, UK, and other Western industrial societies. The annual incidence in Jamaica has shown an upward trend from 1958 to 1974. Compared with Uganda, breast cancer in Jamaica conforms to a "westernized" pattern with regard to the shape of the age-specific incidence curve and stage of presentation. There are no obvious histological differences between breast cancer in Uganda, USA and Jamaica. The incidence of breast cancer in Jamaica appears diaproportionately high in view of the high proportion of early pregnancies occurring in Jamaican women. (AU)

Título: HTLV-I and tropical spastic paraparesis. 2. The human T-cell lymphotropic virus type 1
Fonte: Trans R Soc Trop Med Hyg;83(6):729-31, Nov.-Dec.1989.
Idioma: En.
Resumo: Human T-lymphotropic viruses (HTLV) are casually associated with adult T-cell leukaemia and with a progressive form of lower limb paralysis known as tropical spastic paraparesis. HTLV-I is endemic in parts of Japan, the Caribbean, West Africa and probably South America, and is associated with disease in these areas. Horizontal transmission is probably most common through sexual intercourse which, it is postulated, must be more prevalent in women in endemic areas. Vertical transmission appears to be principally through breast milk. Poor housing and hygiene may facilitate transmission. (AU)

Título: Tropical myeloneuropathies: a new aetiology
Fonte: Trends Neurosci;11(12):526-32, Dec. 1988.
Idioma: En.
Resumo: Tropical myeloneuropathies are a group of neurological disorders known to occur in subtropical and tropical regions. Many aetiologies have been postulated and investigated over the past 100 years, but no single cause has been found. Recent studies suggest that human T-cell lymphotropic virus HTLV-I is the causative agent of one of these tropical myeloneuropathies, endemic tropical spastic paraparesis, and of a related disorder in southern Japan called HTLV-I-associated myelopathy. Endemic tropical spastic paraparesis is now being reported from geographical and climatic regions that were previously thought to be free of these disorders. (AU)
