Avaliação da resposta aos esquemas de tratamento reduzidos para malária vivax
(Universidade Federal do Pará, 2001-08) ABDON, Nagib Ponteira; PINTO, Ana Yecê das Neves; SILVA, Rita do Socorro Uchôa da; SOUZA, José Maria de
Relapses may occur with long standard treatment of vivax malaria, and these are caused by incomplete patient’s compliance. The use of reduced schedules may further better patient compliance, while maintaining the same efficacy, tolerance and minimal adverse reactions. The objective of this study was to test two schedules with reduced doses of chloroquine for vivax malaria and comparing these with the classical schedule. The authors studied 120 outpatients, with vivax malaria, aged over 12 years, submitted to three therapeutic schemes: scheme I: chloroquine phosphate (150mg) in a dose of 25mg/kg/day for three days (10mg/kg/ day in the first day, 7.5mg/kg/day in the second and third day), plus primaquine (15mg) in a dose of 0.25mg/kg/day for fourteen days; scheme II: chloroquine, in a single dose of 10mg/kg, plus primaquine in a dose of 0.5mg/kg/day for seven days; scheme III: chloroquine, 10mg/kg in a single dose plus primaquine in a dose 0.5mg/kg/ day for five days. The clinical response to all three therapeutic schemes was satisfactory. The disappearance of malarial symptoms occurred after a maximum 96 hours of treatment, while the assexual parasitaemia clearance occurred within 72 hours, in all therapeutic schemes.

Filariose linfática em Belém, Estado do Pará, Norte do Brasil e a perspectiva de eliminação
(Universidade Federal do Pará, 2005-04) FONTES, Gilberto; FRAIHA NETO, Habib; ROCHA, Eliana Maria Mauricio da; BRAUN, Reinaldo F.; VIEIRA, João Batista F.; PADILHA, Saturnino S.; ROCHA, Raimundo Cândido
The objective was to characterize the epidemiological situation of lymphatic filariasis in Belém, state of Pará. Hemoscopic data was analyzed from 1951 through 2003. Information for the period from 1951 to 1994 was collected from reports available from the National Health Foundation. Data from 1995 to 2003 was obtained through surveys carried out in 62 city sectors, within the eight administrative districts of the city. An appreciable drop in the microfilaraemic rates was observed over the years. The percentages of parasitized individuals in the decades of 1950, 1960, 1970, 1980 and 1990, were respectively: 8.2%, 2.6%, 0.7%, 0.16% and 0.02%. In 2001, a single microfilaraemic case was diagnosed, interrupting a series of two years without registering positive cases in the city. In 2002 and 2003, hemoscopic and entomological surveys were performed simultaneously revealing no microfilariae positive individuals, nor infected mosquitoes. To maintain this trend, surveillance measures must be conducted in order to detect and promptly treat patients, to prevent the risk of resurgence of a focus apparently now controlled.

Manifestações emocionais e motoras de ribeirinhos expostos ao mercúrio na Amazônia
(Universidade Federal do Pará, 2017-06) COSTA JÚNIOR, José Maria Farah; LIMA, Abner Ariel da Silva; RODRIGUES JÚNIOR, Dario; KHOURY, Eliana Dirce Torres Khoury; SOUZA, Givago da Silva; SILVEIRA, Luiz Carlos de Lima
Introduction: The investigation of clinical and neurological impactations associated with exposure to mercury levels in exposed populations is necessary in the Amazon. Objective: To analyze emotional and motor symptoms of riverside dwellers exposed by diet in the municipalities of Itaituba and Acará, in Pará, Brazil. Methods: Hair samples were collected to assess the total mercury (HgT). Demographic data as well as emotional (depression, anxiety and insomnia) and motor (paresthesia, muscle weakness, loss of balance when walking, tremors, limb pain and dysarthria) symptomatology data were obtained. Results: Mean levels of HgT in Itaituba were significantly higher (p < 0.0001) than in Acará. Emotional symptoms were identified in 26 (26.5%) participants from Itaituba and in 24 (52.2%) from Acará. Specific motor complaints in Itaituba occurred in 63 (64.3%) volunteers; the most frequently mentioned afflictions were limb pain (36.7%), paresthesia (32.6%) and muscle weakness (27.5%). In Acará, 33 (71.7%) participants had motor symptoms, the majority of which complained of paresthesia (54.3%), limb pain (52.2%) and tremors (34.8%). Average HgT levels in Itaituba in those with emotional and motor symptoms were above the tolerable levels (6 μg/g) determined by the World Health Organization. Conclusion: Results showed that mercury levels in emotional and motor symptoms in Itaituba are higher than in riverside dwellers in Acará. Further studies, including the application of specific qualitative and/or quantitative standard tests, as well as the investigation of other clinical signs are necessary.
