Objectives: To evaluate factors related to dangerousness cessation at the end of involuntary commitment based on an analysis of expert reports. In light of the current legal requirement of dangerousness cessation as a pre-requisite for prison or internment release of individuals subjected to the safety measure, we sought elements to reflect on the practice of expert examiners in charge of making this decision. Methods: The authors revised 224 expert psychiatric dangerousness cessation reports released 2011 through 2014 and collected data for a statistical analysis. Results: The following variables were associated with positive risk cessation assessments: no inadequate behavior (according to the assistant professionals), no productive psychotic symptoms, no negative symptoms, presence of insight, presence of a support network, and no psychoactive substance abuse. The following variables were associated with negative dangerousness cessation decisions: early onset of malfunction, lack of insight, negative attitudes, active signs of major mental illness, presence of impulsiveness, poor response to treatment, presence of plans lacking feasibility, exposure to destabilizing factors, lack of personal support, and presence of stress. Conclusions: In this study we were able to identify factors associated with dangerousness in a sample of expert reports. The knowledge of factors linked to a higher risk of recidivism in illegal activities or violent behavior is crucial for decision-making regarding the release of offenders after their legally established period of involuntary commitment.

A Leishmania donovani-complex specific DNA probe was usedto confirm the widespread dissemination of amastigotes in apparently normal skinof dogs with canine visceral leishmaniasis. When Lutzomyia longipalpis were fed on abnormal skin of five naturally infected dogs 57 of 163 (35 per cent) fliesbecame infected: four of 65 flies (6 per cent) became infected when fed on apparently normal skin. The bite of a single sandfly that had fed seven days previouslyon a naturally infected dog transmitted the infection to a young dog from a non-endemic area. Within 22 days a lesion had developed at the site of the infectivebite (inner ear): 98 days after infection organisms had not disseminated throughout the skin, bone marrow, spleen or liver and the animal was still serologically negative by indirect immunofluorescence and dot-enzyme-linked immunosorbent assay. When fed Lu. longipalpis were captured from a kennel with a sick dog known to be infected, 33 out of 49 (67 per cent) of flies contained promastigotes. In contrast only two infections were detected among more than 200 sandflies captured in houses. These observations confirm the ease of transmissibility of L.chagasi from dog to sandfly to dog in Teresina. It is likely that canine VL is the major source of human VL by the transmission route dog-sandfly-human. the Lmet2 DNA probe was a useful epidemiological tool for detecting L. chagasi in sandflies.

Os autores apresentam os resultados do estudo epidemiológico de um caso autóctone da fase aguda da doença de Chagas na ilha do Mosqueiro, Estado do Pará, aproximadamente 75km da capital, Belém. 0 caso já havia sido objeto de uma publicação anterior. Agora são apresentadas informações epidemiológicas. Nas proximidades da casa do paciente foram capturados em duas palmeiras de Inajá ('Maximilian regi ay e em uma de Mucajá (Acrocomia sclerocarpia) 114 triatomíneos: Rhodnius pictipes, R. robustus, Panstrongylus lignarius, P. geniculatus e Microtriatoma trinidadensis, com tripanossomas em 31 deles. Na casa do paciente foram encontrados exemplares de Rhodnius pictipes, infectados com formas metacíclicas do Trypanosoma cruzi. Em 14 marsupiais, capturados na localidade, haviam 3 infectados com organismos semelhantes ao T. cruzi. A eletroforese dos isoenzimas nos tripanossomas isolados do paciente, de R. pictipes e de Didelphis marsupialis os classificou como zimodema 1. Os autores concluem que a doença de Chagas do paciente teve origem silvestre.

The authors present the results of an epidemiological study relating to a case of acute Chagas' disease acquired in the island of Mosqueiro, State of Para, approximately 75 km from the capital Belem. The patient has been the object of a previous publication but now epidemiological information is reported. Near the house of the patient in two Inaja palm trees (Maximilian regia) and one Mucaja palm (Acrocomia sclerocarpia) 114 triatomine bugs were captured of the following species: Rhodnius pictipes, R. robustus, Panstrongylus lignarius, P. geniculatus and Microtriatoma trinidadensis. Trypanosomes were found in 31 bugs. In the house of the patient specimens of R. pictipes were captured infected with metacyclic forms óf Trypanosoma cruzi. In 14 marsupials captured in the locality three had infections with cruzi like trypanosomes. Enzyme electrophoresis of the trypanosomes isolated from the patient, R. pictipes and Didelphis marsupialis were classified as zymodeme 1. The authors conclude that the patients Chagas' disease was of sylvatic origin.

Rhodnius robustus e/ou Rhodnius pictipes, infectados com Trypanosoma cruzi foram comumente encontrados, em grande numero, nas palmeiras Maximiliana regia (inaja), Acrocomia sclerocarpa (mucaja) e Orbignya speciosa (babacu) na Amazonia brasileira. O marsupial Didelphis marsupialis foi o animal encontrado mais frequentemente nas palmeiras associadas a alta prevalencia de triatomineos. R. pictipes que e atraido pela luz nas residencias de palmeiras vizinhas, provavelmente e a fonte de um caso agudo de doenca de Chagas nas vizinhancas de Belem. Sugere-se que as palmeiras albergando triatomineos poderiam ser relacionadas com infeccoes humanas de doenca de Chagas nos Estados de Amazonas e Rondonia. Sugere-se, tambem, possiveis metodos de controle.

Trypanosoma cruzi infected Rhodnius robustus and/or Rhodnius pictipes were commonly found, in large numbers, in the Brazilian Amazonian palms Maximiliana regia ("inajá"), Acrocomia sclerocarpa ("mucajá") and Orbignya speciosa ("babaçu"). The common opossum, Didelphis marsupialis, was the animal most frequently associated with triatomine infested palms. R. pictipes, frequently light-attracted into houses from palm trees, was the probable source of an acute case of Chagas' disease in the vicinity of Belém. It is considered that triatomine infested palms are likely to cause some cases of acute Chagas' disease in the States of Amazonas and Rondônia. Possible control methods are suggested.
