SEPTIC SHOCK IN PATIENT WITH DISSEMINATED HISTOPLASMOSIS ASSOCIATED WITH AIDS: A CASE REPORT

SUMMARY Histoplasmosis is a systemic mycosis caused by Histoplasma capsulatum, which may present itself as a serious infection in immunocompromised individuals. We present a case of 31-year-old female with newly diagnosed HIV infection and history of fever, general and respiratory symptoms and diffuse hyperchromic papules through the body. She was admitted, with rapid progression to septic shock, and the presence of neutrophils filled with yeast-like organisms was detected on peripheral blood smear hematoscopia on the third day of hospitalization. The following is a brief review on the clinical picture and management of histoplasmosis.

Infrequency of asymptomatic malaria in an endemic area in Amazonas, Brazil

A malaria survey was conducted in an area of high transmission (Costa Marques, Rondonia, Brazil) to determine the prevalence of asymptomatic parasitemia and its clinical significance. Most of the people surveyed were immigrants who had lived in the endemic area < 5 years. The people had easy access to free diagnostic and treatment services at the Malaria Clinic in the town of Costa Marques. The prevalence of plasmodial parasitemia in 344 people was 22%. There were 36 individuals with asymptomatic infections among the 77 parasitemic patients. During the two days following the initial examination, 19 ofthe 36 individuals: with asymptomatic infections developed malaria. Among the 17 patients who remained asymptomatic for > 2 days, 4 had only gametocytes, 1 had taken inadequate anti-malarial treatment, 3 were under treatment and 2 moved. Six asymptomatic patients denied the use of anti-malarial drugs and they developed malaria 3-6 days after the initial parasitological diagnosis. The final patient remained asymptomatic during the 7 day observation period. He had a history of > 40 malaria attacks and denied the use of antimalarial treatment. With the exception of the latter all of the other asymptomatic patients, were either in the incubation period or had been treated It is concluded that asymptomatic malaria is rare in the Costa Marques area and that it is necessary to treat all individuals with plasmodial parasitemia.

American cutaneous leishmaniasis: presentation and problems of patient management

We report our experience with the diagnosis and treatment of 60 patients with American cutaneous leishmaniasis. They were infected in Panama (55), Brazil (4) or Colombia (I). Among 35 patients with a 3 week exposure in Panama, the mean maximum incubation period was 33 days (range 4-81 days). Diagnosis was delayed an average of 93 days after onset of skin lesions, due to the patient's delay in seeking medical attention (31 days), medical personnel's delay in considering the diagnosis (45 days), and the laboratory's delay in confirming the diagnosis (17 days). Forty-four patients (73%) developed ulcers typical of cutaneous leishmaniasis. Sixteen additional patients (27%) had atypical macular, papular, squamous, verrucous or acneiform skin lesions that were diagnosed only because leishmanial cultures were obtained. Of the 59 patients treated with pentavalent antimonial drugs, only 34 (58%) were cured after the first course of treatment. Lesions which were at least 2 cm in diameter, ulcerated, or caused by Leishmania braziliensis were less likely to be cured after a single course of treatment than were lesions smaller than 2 cm, nonulcerated or caused by Leishmania mexicana or Leishmania donovani.

Renewable energy systems the theme for the PACITA summer school on TA, Liège, Belgium, 25 28 June 2012

The summer school “Renewable Energy Systems: Role and Use of Parliamentary Technology Assessment” was the first European Summer School with a pure focus on technology assessment. The aim of the three-day long summer school of the European project Parliaments and Civil Society in Technology Assessment (PACITA) was to create awareness of the potential of technology groups in Europe. Therefore, the summer school involved keynotes, practical exercises, mutual reflection, cutting edge training and networking to deal with the theme of renewable energy systems out of the perspective of Technology Assessment (TA), to meet transition objectives or to critically assess energy technologies.

Spotted fever rickettsiosis in Coronel Fabriciano, Minas Gerais State

We report cases of spotted fever rickettsiosis in Coronel Fabriciano Municipality of Minas Gerais State, Brazil. The cases occurred in May and June of 2000. During this period there were two deaths among children from an area named Pedreira in a periurban area of this municipality. In a boy who died with clinical manifestations of Brazilian spotted fever, a necropsy revealed the presence of a spotted fever group Rickettsia. The serological results confirm the difficulty in the differential diagnosis of patients with symptoms of rickettsial diseases.

Clinical and laboratorial evidence of Rickettsia felis infections in Latin America

After the discovery and initial characterization of Rickettsia felis in 1992 by Azad and cols, and the subsequent first description of a human case of infection in 1994, there have been two communications of human rickettsiosis cases caused by Rickettsia felis in Latin America. The first one was published in 2000 by Zavala-Velazquez and cols in Mexico. In 2001 Raoult and cols described the occurrence of two human cases of Rickettsia felis rickettsiosis in Brazil. In the present discussion these two articles were compared and after the description of the principal signs and symptoms, it was concluded that more studies are needed with descriptions of a greater number of patients to establish the true frequency of the clinical signs and symptoms present in Rickettsia felis rickettsiosis.

Focos de dirofilariose canina na Ilha do Marajó: um fator de risco para a saúde humana

A ocorrência de dirofilariose pulmonar humana relaciona-se com a prevalência de infecção por Dirofilaria immitis na população canina. Várias espécies de mosquitos são vetores desse nematóide. Analisaram-se amostras de sangue canino coletados nas vilas Pingo d'Água e União, município de Salvaterra (Ilha do Marajó, PA), em junho, 2004 (n=34) e abril, 2005 (N=90). Os diagnósticos parasitológico e imunológico (ELISA - kit SNAP® 3DX™, Biobrasil) foram comparados (chi2, alfa=0,05) no exame de 34 amostras. A prevalência na população (N=90) foi avaliada pelo ELISA. O ELISA revelou mais positivos (25/34; 73,5%) que a gota espessa (23/34, 67,6%) e o Knott (21/34, 61,8%), mas a diferença não foi significativa (p>0,05). A freqüência de infecção por D. immitis na faixa de 0 a 2 anos foi 58%, enquanto em cães mais velhos foi 100%. A prevalência da dirofilariose canina em Pingo d'Água e Vila União foi alta (53,5%), indicando risco de transmissão do parasito às pessoas nessa área.

O Arquivo Gama Lobo Salema (sécs. XV – XX): temas e problemas entre a História e a Arquivística

Longe das premissas de «objectividade» e «cientificidade» positivistas, que promoviam a Arquivística como «ciência auxiliar» da História, os arquivistas como “guardiães passivos” 2 da documentação ao ser- viço dos historiadores e os arquivos como “resíduos naturais e orgânicos da actividade humana” 3 virginal- mente conservados ao longo dos séculos, as últimas décadas trouxeram novos pressupostos lançados por uma, também ela, «Nova Arquivística», progressivamente sintonizada com os desafios pós-modernistas com as exigências da Era da Informação. Autónoma, metamorfoseada e ao abrigo de um novo paradigma, esta «ciência» arquivística renovada depressa contaminou a sua antiga disciplina-mãe ao chamar particular atenção para a necessidade de rever algumas das tendências - ou “resíduos tóxicos” 5 para usar uma expressão de Patrick Geary – de herança positivista. Dessa contaminação resultaram dois movimentos essenciais que marcam o compasso de diversas das principais discussões hoje tecidas acerca da metodologia e da teoria da História: o archival turn (“viragem arquivística”), sobretudo animado pela produção científica ligada aos EUA, Inglaterra e Canáda; e o tournant documentaire (“viragem documental”), propagado por autores oriundos de França, Bélgica, Espanha, Itália e, em menor medida, Portugal. Apesar de cada uma destas viragens apresentar características específicas ambas partilham, no entanto, uma mesma essência que aponta precisamente para a concepção dos arquivos (tanto os conjuntos documentais como as instituições) não só como “place of study”, isto é, como espaços e repositórios de informação passível de ser recolhida para a análise de dado objecto de estudo mas também como objectos de estudo em si mesmos, per se merecedores de um esforço problematizante. Esta centralidade ocupada pelos conjuntos documentais, pelos arquivos-instituição e, consequentemente, pelo trabalho desenvolvido pelos arquivistas provocou, por seu turno, um intenso questionamento de algumas das mais enraizadas «evidências» cultivadas no seio da Historiografia.
