    World malaria report 2013.

    World Health Organization [WHO]. Global Malaria Programme

    Geneva, Switzerland, WHO, 2013. [284] p.

    The World Malaria Report 2013 summarizes information received from malaria-endemic countries and other sources, and updates the analyses presented in the 2012 report. It highlights the progress made towards global malaria targets set for 2015, and describes current challenges for global malaria control and elimination.

    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.

    Tropical Medicine and International Health. 2007 Nov; 12(11):1377-1385.

    The objective was to assess the effect of vaccines against pneumonia in Gambian children. Data from a randomized, controlled trial of a 9-valent pneumococcal conjugate vaccine (PCV) were used. Radiographic findings, interpreted using WHO definitions, were classified as primary end point pneumonia, 'other infiltrates / abnormalities' pneumonia and pneumonia with no abnormality. We calculated the incidence of the different types of radiological pneumonia, and compared clinical and laboratory features between these groups. Among children who did not receive PCV, the incidence of pneumonia with no radiographic abnormality was about twice that of 'other infiltrates' pneumonia and three times that of primary endpoint pneumonia. Most respiratory symptoms, reduced feeding and vomiting occurred most frequently in children with primary endpoint pneumonia. These children were more likely to be malnourished, to have bronchial breath sounds or invasive bacterial diseases, and to die within 28 days of consultation than children in the other groups. Conversely, a history of convulsion, diarrhoea or fast breathing, malaria parasitaemia and isolation of salmonellae were commoner in children with pneumonia with no radiographic abnormality. Lower chest wall indrawing and rhonchi on auscultation were seen most frequently in children with 'other infiltrates / abnormalities' pneumonia. Primary endpoint pneumonia is strongly associated with bacterial aetiology and severe pneumonia. Since this category of pneumonia is significantly reduced after vaccination with Hib and pneumococcal vaccines, the risk-benefit of antimicrobial prescription for clinical pneumonia for children with increased respiratory rate may warrant re-examination once these vaccines are in widespread use.
