[Clinical, epidemiological and microbiological characteristics of a cohort of pulmonary tuberculosis patients in Cali, Colombia] Caracteristicas clinicas, epidemiologicas y microbiologicas de una cohorte de pacientes con tuberculosis pulmonar en Cali, Colombia.
Biomedica. 2010 Oct-Dec; 30(4):482-91.INTRODUCTION: The World Health Organization recommended strategy for global tuberculosis control is a short-course, clinically administered treatment, This approach has approximately 70% coverage in Colombia. OBJECTIVE: The clinical, epidemiological and microbiological characteristics along with drug therapy outcomes were described in newly diagnosed, pulmonary tuberculosis patients. MATERIALS AND METHODS: This was a descriptive study, conducted as part of a multicenter clinical trial of tuberculosis treatment. A cohort of 106 patients with pulmonary tuberculosis were recruited from several public health facilities in Cali between April 2005 and June 2006. Sputum smear microscopy, culture, drug susceptibility tests to first-line anti-tuberculosis drugs, chest X- ray and HIV-ELISA were performed. Clinical and epidemiological information was collected for each participant. Treatment was administered by the local tuberculosis health facility. Food and transportation incentives were provided during a 30 month follow-up period. RESULTS: The majority of patients were young males with a diagnostic delay longer than 9 weeks and a high sputum smear grade (2+ or 3+). The initial drug resistance was 7.5% for single drug treatment and 1.9% for multidrug treatments. The incidence of adverse events associated with treatment was 8.5%. HIV co-infection was present in 5.7% of the cases. Eighty-six percent of the patients completed the treatment and were considered cured. The radiographic presentation varied within a broad range and differed from the classic progression to cavity formation. CONCLUSION: Delay in tuberculosis diagnosis was identified as a risk factor for treatment compliance failure. The study population had similar baseline epidemiologic characteristics to those described in other cohort studies.
The WHO dengue classification and case definitions: time for a reassessment. [Clasificación del dengue y definición de casos de la OMS: tiempo de una nueva evaluación]
Lancet. 2006 Jul 8; 368(9530):170-173.Dengue is the most prevalent mosquito-borne viral disease in people. It is caused by four dengue virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus, and transmitted by Aedes aegypti mosquitoes. Infection provides life-long immunity against the infecting viral serotype, but not against the other serotypes. Although most of the estimated 100 million dengue virus infections each year do not come to the attention of medical staff , of those that do, the most common clinical manifestation is non-specific febrile illness or classic dengue fever. About 250 000--500 000 patients developing more severe disease. The risk of severe disease is several times higher in sequential than in primary dengue virus infections. Despite the large numbers of people infected with the virus each year, the existing WHO dengue classification scheme and case definitions have some drawbacks. In addition, the widely used guidelines are not always reproducible in different countries--a quality that is crucial to effective surveillance and reporting as well as global disease comparisons. And, as dengue disease spreads to different parts of the globe, several investigators have reported difficulties in using the system, and some have had to create new categories or new case definitions to represent the observed patterns of disease more accurately.

The global eradication of smallpox. Final report of the Global Commission for the Certification of Smallpox Eradication, Geneva, December 1979.
Geneva, Switzerland, WHO, 1980. 122 p. (History of International Public Health No. 4)The Global Commission for the Certification of Smallpox Eradication met in December 1978 to review the program in detail and to advise on subsequent activities and met again in December 1979 to assess progress and to make the final recommendations that are presented in this report. Additionally, the report contains a summary account of the history of smallpox, the clinical, epidemiological, and virological features of the disease, the efforts to control and eradicate smallpox prior to 1966, and an account of the intensified program during the 1967-79 period. The report describes the procedures used for the certification of eradication along with the findings of 21 different international commissions that visited and reviewed programs in 61 countries. These findings provide the basis for the Commission's conclusion that the global eradication of smallpox has been achieved. The Commission also concluded that there is no evidence that smallpox will return as an endemic disease. The overall development and coordination of the intensified program were carried out by a smallpox unit established at the World Health Organization (WHO) headquarters in Geneva, which worked closely with WHO staff at regional offices and, through them, with national staff and WHO advisers at the country level. Earlier programs had been based on a mass vaccination strategy. The intensified campaign called for programs designed to vaccinate at least 80% of the population within a 2-3 year period. During this time, reporting systems and surveillance activities were to be developed that would permit detection and elimination of the remaining foci of the disease. Support was sought and obtained from many different governments and agencies. The progression of the eradication program can be divided into 3 phases: the period between 1967-72 when eradication was achieved in most African countries, Indonesia, and South America; the 1973-75 period when major efforts focused on the countries of the Indian subcontinent; and the 1975-77 period when the goal of eradication was realized in the Horn of Africa. Global Commission recommendations for WHO policy in the post-eradication era include: the discontinuation of smallpox vaccination; continuing surveillance of monkey pox in West and Central Africa; supervision of the stocks and use of variola virus in laboratories; a policy of insurance against the return of the disease that includes thorough investigation of reports of suspected smallpox; the maintenance of an international reserve of freeze-dried vaccine under WHO control; and measures designed to ensure that laboratory and epidemiological expertise in human poxvirus infections should not be dissipated.
USAID HIGHLIGHTS. 1991 Fall; 8(3):1-4.This article considers the epidemic proportion of AIDS in developing countries, and discusses the U.S. Agency for International Development's (USAID) reworked and intensified strategy for HIV infection and AIDS prevention and control over the next 5 years. Developing and launching over 650 HIV and AIDS activities in 74 developing countries since 1986, USAID is the world's largest supporter of anti-AIDS programs. Over $91 million in bilateral assistance for HIV and AIDS prevention and control have been committed. USAID has also been the largest supporter of the World Health Organization's Global Program on AIDS since 1986. Interventions have included training peer educators, working to change the norms of sex behavior, and condom promotion. Recognizing that the developing world will increasingly account for an ever larger share of the world's HIV-infected population, USAID announced an intensified program of estimated investment increasing to approximately $400 million over a 5-year period. Strategy include funding for long-term, intensive interventions in 10-15 priority countries, emphasizing the treatment of other sexually transmitted diseases which facilitate the spread of HIV, making AIDS-related policy dialogue an explicit component of the Agency's AIDS program, and augmenting funding to community-based programs aimed at reducing high-risk sexual behaviors. The effect of AIDS upon child survival, adult mortality, urban populations, and socioeconomic development in developing countries is discussed. Program examples are also presented.
