Dysarthria in hereditary spastic paraplegia type 4

Abstract Objective: To describe the speech pattern of patients with hereditary Spastic Paraplegia type 4 (SPG4) and correlated it with their clinical data. Methods: Cross-sectional study was carried out in two university hospitals in Brazil. Two groups participated in the study: the case group (n = 28) with a confirmed genetic diagnosis for SPG4 and a control group (n = 17) matched for sex and age. The speech assessment of both groups included: speech task recording, acoustic analysis, and auditory-perceptual analysis. In addition, disease severity was assessed with the Spastic Paraplegia Rating Scale (SPRS). Results: In the auditory-perceptual analysis, 53.5% (n = 15) of individuals with SPG4 were dysarthric, with mild to moderate changes in the subsystems of phonation and articulation. On acoustic analysis, SPG4 subjects' performances were worse in measurements related to breathing (maximum phonation time) and articulation (speech rate, articulation rate). The articulation variables (speech rate, articulation rate) are related to the age of onset of the first motor symptom. Conclusion: Dysarthria in SPG4 is frequent and mild, and it did not evolve in conjunction with more advanced motor diseases. This data suggest that diagnosed patients should be screened and referred for speech therapy evaluation and those pathophysiological mechanisms of speech involvement may differ from the length-dependent degeneration of the corticospinal tract.

Plantar ulcer as an atypical manifestation of cutaneous leishmaniasis

Abstract Cutaneous leishmaniasis is characterized by ulcers with raised edges and a granular bottom, mainly on the lower limbs. This is a case report of a male patient with an ulcer on the left plantar region. The diagnosis was confirmed by positive PCR for L. braziliensis and the presence of amastigotes of Leishmania sp. in the histopathological examination. After treatment with Glucantime, the patient showed full healing of the ulcer. The unusual location of the ulceration calls attention to atypical presentations of leishmaniasis, and the importance of histopathological examination and PCR, leading to the appropriate diagnosis and treatment.

Uma abordagem integral para saneamento ecológico em comunidades tradicionais e rurais / An integral approach of ecological sanitation in traditional and rural communities

Resumo Este artigo apresenta uma abordagem integral para atuar em projetos comunitários, baseada nas três ecologias de Guattari e do seu diálogo com teóricos da psicossociologia, por envolver a necessidade de conjugar intervenções tecnológicas com abordagens sociais. Explora-se essas contribuições para apontar a necessidade do diálogo na implementação de ações de saneamento, principalmente na zona rural e em Comunidades Tradicionais, envolvendo o indivíduo, os grupos atendidos e sua cultura territorial. A abordagem apresentada foi implementada em uma pequisa-ação, junto com a Comunidade Caiçara da Praia do Sono e o Fórum de Comunidades Tradicionais de Angra dos Reis, Paraty e Ubatuba (FCT), a partir do projeto Observatório de Territórios Sustentáveis e Saudáveis da Bocaina (OTSS/Fiocruz). Pode-se constatar que a inclusão dos atores na mobilização social para o saneamento pode estabelecer uma participação social efetiva, que gere tanto uma mudança subjetiva na consciência dos diversos atores locais, como ganhos estruturais que promovam saúde e qualidade de vida. O panorama abordado mostra a importância de uma compreensão global do problema, mas também, simultaneamente, uma atuação local, territorializada, adaptada a cada realidade por meio do diálogo genuíno e uma participação horizontal.

Abstract This article presents an integral approach to work in community projects, based on Guattari's three ecologies and its dialogue with psychosocial theorists, since it involves the need to combine technological interventions with social approaches. These contributions are explored to point out the need for dialogue in the implementation of sanitation actions, mainly in the rural area and in traditional communities, involving the individual, the groups served and their territorial culture. The approach presented was implemented in a joint action with the Caiçara Community of Praia do Sono and the Forum of Traditional Communities of Angra dos Reis, Paraty and Ubatuba (FCT), based on the Observatory of Sustainable and Healthy Territories of Bocaina (OTSS / Fiocruz). It could be verified that the inclusion of the actors in the social mobilization for the sanitation can entail an effective social participation that generates both a subjective change in the conscience of the diverse local actors and structural gains that promote health and quality of life. The panorama covered shows the importance of a global understanding of the problem, but also, of a simultaneous local, territorialized action, adapted to each reality through genuine dialogue and horizontal participation.

O comum e os desdobramentos na economia solidária a partir do saneamento ecológico / The common and the unfolding in the solidarity economy from ecological sanitation

Resumo Como as condições de saneamento no Brasil são precárias nas áreas rurais, é importante construir ações territorializadas que valorizem a cultura e fortaleçam o bem viver, baseadas na economia solidária para alcançar soluções sustentáveis​. Dardot e Laval veem o comum como um contraponto ao atual contexto político e econômico, em que os indivíduos assumem o papel de protagonistas em suas vidas e gerenciam os "comuns" para a comunidade da qual fazem parte. Partindo dessa abordagem, a Fundação Osvaldo Cruz (Fiocruz), por meio do Observatório dos Territórios Saudáveis e Sustentáveis de Bocaina (OTSS), constituiu pesquisa-ação de saneamento ecológico na Comunidade Caiçara da Praia do Sono, em Paraty, com envolvimento da comunidade durante todo o processo e, por meio de avaliação qualitativa, pôde-se entender a relação da comunidade com o comum. Como os construtores locais foram contratados como mobilizadores sociais, os recursos endógenos foram valorizados. Por meio dessa articulação, buscou-se a atuação conjunta junto aos órgãos públicos para fomentar ações que partissem da própria comunidade e políticas públicas inclusivas que colocam a sociedade como protagonista do processo. A partir do conceito de comum e de entrevistas semiestruturadas, esta pesquisa psicossocial tem como objetivo relatar o desdobramento da economia solidária no comum.

Abstract As sanitation conditions in Brazil are precarious in rural areas, it is important to build territorial actions that value culture and strengthen good living based on solidarity economy to achieve sustainable solutions. Dardot and Laval see the "common" as a counterpoint to the current political and economic context, in which individuals assume the role of protagonists in their lives and manage the "commonalities" for their community. In this approach, the Oswaldo Cruz Foundation (Fiocruz), through the Observatory of Sustainable and Healthy Territories of Bocaina (OTSS), constituted an ecological sanitation research in the Caiçara Community of Praia do Sono, in Paraty, with the participation of the community during the whole process and, through a qualitative evaluation, the relationship between the community and the common could be understood. Local builders were hired as social mobilizers, thus valuing endogenous resources. Through this articulation, joint action with public agencies was sought to foster actions that came from the community itself and inclusive public policies that put a society at the center of the process. Supported by the concept of common and by semi-structured interviews, this psychosocial study examines the unfolding of the solidarity economy.

COMVC-19: A Program to protect healthcare workers' mental health during the COVID-19 Pandemic. What we have learned

OBJECTIVE: In 2020, the COVID-19 pandemic brought a work and stress overload to healthcare workers, increasing their vulnerability to mental health impairments. In response, the authors created the COMVC-19 program. The program offered preventive actions and mental health treatment for the 22,000 workers of The Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). This paper aims to describe its implementation and share what we have learned from this experience. METHODS: Workers were able to easily access the program through a 24/7 hotline. Additionally, a mobile phone app that screened for signs and symptoms of emotional distress and offered psychoeducation and/or referral to treatment was made available. Data from both these sources as well as any subsequent psychiatric evaluations were collected. RESULTS: The first 20 weeks of our project revealed that most participants were female, and part of the nursing staff working directly with COVID-19 patients. The most frequently reported symptoms were: anxiety, depression and sleep disturbances. The most common diagnoses were Adjustment, Anxiety, and Mood disorders. CONCLUSIONS: Implementing a mental health program in a multimodal intervention was feasible in a major quaternary public hospital. Our data also suggests that preventive actions should primarily be aimed at anxiety and depression symptoms, with a particular focus on the nursing staff.

Effects of photobiomodulation therapy on functional recovery, angiogenesis and redox status in denervated muscle of rats / Efeitos da terapia de fotobiomodulação na recuperação funcional, na angiogênese e no estado redox em músculo desnervado de ratos

ABSTRACT Objective: To evaluate the effects of photobiomodulation therapy in redox status, angiogenesis marker - vascular endothelial growth factor - and in the functional recovery in denervated muscle. Methods: A total of 32 female Wistar rats underwent a crush injury and were randomly divided into four groups: Light Emitting Diode Group 2 and Control Group 2 (muscle collected 2 days after injury), and Light Emitting Diode Group 21 and Control Group 21 (muscle collected 21 days afterinjury). Light Emitting Diode Group 2 and Light Emitting Diode Group 21 received two and ten light emitting diode applications (630±20nm, 9J/cm2, 300mW), respectively, and the Control Group 2 and Control Group 21 did not receive any treatment. The function was evaluated by grasping test at four moments (pre-injury, 2, 10 and 21 post-injury days). The flexor digitorum muscle was collected for analysis of immunolocalization of vascular endothelial growth factor and redox parameters. Results: Functional improvement was observed at the second and tenth post-injury day in treated groups compared to control (p<0.005). The muscle tissue of treated groups presented higher immunohistochemical expression of vascular endothelial growth factor. Photobiomodulation therapy decreased the oxidative damage to lipid in Light Emitting Diode Group 2 compared to Control Group 2 (p=0.023) in the denervated muscle. Conclusion: Photobiomodulation therapy accelerated the functional recovery, increased angiogenesis and reduced lipid peroxidation in the denervated muscle at 2 days after injury.

RESUMO Objetivo: Avaliar os efeitos da terapia de fotobiomodulação no estado redox, no marcador de angiogênese - fator de crescimento endotelial vascular - e na recuperação funcional do músculo desnervado. Métodos: Um total de 32 ratas Wistar foi submetido a uma lesão por esmagamento e dividido aleatoriamente em quatro grupos: Grupo Diodo Emissor de Luz 2 e Grupo Controle 2 (músculo coletado 2 dias após a lesão), além do Grupo Diodo Emissor de Luz 21 e do Grupo Controle 21 (músculo coletado 21 dias após a lesão). Grupo Diodo Emissor de Luz 2 e Grupo Diodo Emissor de Luz 21 receberam duas e dez aplicações de diodo emissor de luz (630±20nm, 9J/cm2e 300mW), respectivamente, e Grupo Controle 2 e Grupo Controle 21 não receberam tratamento. A função foi avaliada pelo teste de preensão em quatro momentos (pré-lesão, 2, 10 e 21 dias após a lesão). O músculo flexor dos dedos foi coletado para análise dos parâmetros redox e da imunolocalização do fator de crescimento endotelial vascular. Resultados: Houve melhora funcional no segundo e décimo dia pós-lesão nos grupos tratados em comparação aos controles (p<0,005). O tecido muscular dos grupos tratados apresentou maior expressão imuno-histoquímica do fator de crescimento endotelial vascular. A terapia de fotobiomodulação diminuiu o dano oxidativo aos lipídeos no Grupo Diodo Emissor de Luz 2 comparado ao Grupo Controle 2 (p=0,023) no músculo desnervado. Conclusão: A terapia de fotobiomodulação acelerou a recuperação funcional, aumentou a angiogênese e reduziu a peroxidação lipídica no músculo desnervado 2 dias após a lesão.

Sarcoidose como diagnóstico diferencial de mieloma múltiplo / Sarcoidosis as a differential diagnosis of multiple myeloma

A sarcoidose caracteriza-se como doença granulomatosa que acomete diferentes órgãos humanos, especialmente os pulmões, sendo sua patogênese pouco conhecida. No caso em questão, a paciente iniciou com sintomas inespecíficos, como fraqueza, perda ponderal e tosse seca esporádica, sendo internada para extensão da propedêutica. Sugeriu-se como hipótese diagnóstica inicial possível quadro de mieloma múltiplo, tendo em vista a anemia, a disfunção renal, a hipercalcemia e, sobretudo, as lesões osteolíticas apresentadas pela paciente. Todavia, o diagnóstico de sarcoidose foi selado a partir das biópsias de medula óssea e de linfonodo inguinal, que evidenciaram mielite e linfadenite granulomatosas, respectivamente. A terapêutica instituída baseou-se na administração de corticosteroides e em medidas de redução da calcemia. A paciente recebeu alta, com melhora do quadro clínico, para acompanhamento ambulatorial da doença. Conclui-se que a sarcoidose não possui tratamento curativo, mas a terapêutica imunossupressora é eficaz no controle da progressão da enfermidade, fazendo com que o paciente tenha um prognóstico favorável.

Sarcoidosis is characterized as a granulomatous disease that affects different human organs, especially the lungs, and its pathogenesis is little known. In this case, the patient started with nonspecific symptoms, such as weakness, weight loss, and sporadic dry cough, being hospitalized for extension of the propaedeutics. The initial diagnostic hypothesis suggested was a possible case of multiple myeloma, based on the anemia, renal dysfunction, hypercalcemia and, above all, the osteolytic lesions presented by the patient. However, the diagnosis of sarcoidosis was made after bone marrow and inguinal lymph node biopsies that showed granulomatous myelitis and lymphadenitis, respectively. The therapy instituted was based on the administration of corticosteroids and on measures to reduce the level of calcium. The patient was discharged, with clinical improvement, for outpatient follow-up of the disease. It is concluded that sarcoidosis has no curative treatment, but immunosuppressive therapy is effective in controlling the progression of the disease, giving the patient a favorable prognosis.

Prevalence of oropharyngeal dysphagia in hereditary spastic paraplegias / Prevalência de disfagia orofaríngea nas paraparesias espásticas hereditárias

ABSTRACT Hereditary spastic paraplegias (HSP) are a group of genetic diseases characterized by lower limb spasticity with or without additional neurological features. Swallowing dysfunction is poorly studied in HSP and its presence can lead to significant respiratory and nutritional complications. Objectives: The aim of this study was to evaluate the frequency and clinical characteristics of dysphagia in different types of HSP. Methods: A two-center cross-sectional prevalence study was performed. Genetically confirmed HSP patients were evaluated using the Northwestern Dysphagia Patient Check Sheet and the Functional Oral Intake Scale. In addition, self-perception of dysphagia was assessed by the Eat Assessment Tool-10 and the Swallowing Disturbance Questionnaire. Results: Thirty-six patients with spastic paraplegia type 4 (SPG4), five with SPG11, four with SPG5, four with cerebrotendinous xanthomatosis (CTX), three with SPG7, and two with SPG3A were evaluated. Mild to moderate oropharyngeal dysphagia was present in 3/5 (60%) of SPG11 and 2/4 (50%) of CTX patients. A single SPG4 (2%) and a single SPG7 (33%) patient had mild oropharyngeal dysphagia. All other evaluated patients presented with normal or functional swallowing. Conclusions: Clinically significant oropharyngeal dysphagia was only present in complicated forms of HSP Patients with SPG11 and CTX had the highest risks for dysphagia, suggesting that surveillance of swallowing function should be part of the management of patients with these disorders.

RESUMO As paraparesias espásticas hereditárias (PEH) são um grupo de doenças genéticas caracterizado por espasticidade dos membros inferiores com ou sem características neurológicas adicionais. A disfunção da deglutição é pouco estudada nas PEH e sua presença pode levar a complicações respiratórias e nutricionais significativas. Objetivo: O objetivo deste estudo foi avaliar a frequência e a caracterização clínica da disfagia em diferentes tipos de PEH. Métodos: Foi realizado um estudo transversal em dois centros. Os pacientes com PEH confirmados geneticamente foram avaliados pelo Northwestern Dysphagia Patient Check Sheet e pela Escala Funcional de Ingestão Oral. Além disso, a autopercepção da disfagia foi avaliada pelo Eat Assessment Tool-10 e pelo Swallowing Disturbance Questionnaire. Resultados: Trinta e seis pacientes com paraplegia espástica tipo 4 (SPG4), cinco com SPG11, quatro com SPG5, quatro com xantomatose cerebrotendinosa (CTX), três com SPG7 e dois com SPG3A foram avaliados. Disfagia orofaríngea leve a moderada estava presente em 3/5 (60%) dos pacientes com SPG11 e 2/4 (50%) dos pacientes com CTX. Um único SPG4 (2%) e um único SPG7 (33%) apresentaram disfagia orofaríngea leve. Todos os outros pacientes avaliados apresentaram deglutição normal ou funcional. Conclusão: Disfagia orofaríngea clinicamente significativa estava presente apenas nas formas complicadas de PEH. A SPG11 e CTX apresentaram maiores riscos de disfagia, sugerindo que a avaliação da deglutição deve fazer parte do manejo dos pacientes com essas condições.

Disseminated leishmaniasis: clinical, pathogenic, and therapeutic aspects

Abstract: Disseminated leishmaniasis is a severe and emerging form of American tegumentary leishmaniasis. Disseminated leishmaniasis is defined by the presence of more than 10 polymorphic cutaneous lesions, distributed over more than two noncontiguous parts of the body. Nasal mucosal involvement is observed in almost half of cases. Disseminated leishmaniasis patients present with a decreased production of Th1 cytokines in the peripheral blood due to the attraction of leishmania- activated T cells to the multiple cutaneous lesions. Disseminated leishmaniasis development is poorly understood and is related to a complex network involving environmental, host immune response, and parasite factors, in which L. braziliensis polymorphism plays an important role. Disseminated leishmaniasis is a challenging disease to cure, presenting a high failure rate of 75% to pentavalent antimony therapy. Despite its importance and severity, this form of American tegumentary leishmaniasis has been poorly studied and documented, deserving greater attention from professionals working in endemic areas.

Acetylcholinesterase activity and total antioxidant levels in dogs with mammary tumors before and after surgical removal / Actividad de acetilcolinesterasa y niveles totales de antioxidantes en perros con tumores de mama antes y después de la extirpación quirúrgica

ABSTRACT Objective. The aim of this study was to evaluate AChE activity in total blood and the FRAP levels in samples from dogs with mammary tumors before and after surgery, as well as the relationship between these variables with immunohistochemical markers of tumor (E-caderina, ki-67, COX-2). Materials and methods. In this study, 13 dogs with mammary tumors were divided into two groups (A and B). The group A was formed by dogs with tumors smaller than 3 cm of diameter, and the group B was formed by dogs with tumor of 3 cm of diameter or larger. The AChE activity and FRAP levels were evaluated before and after surgery and the immunohistochemistry were performed at the tumors. Results. The AChE activity was significantly increased (p<0.05) in dogs with mammary cancer compared to control animals, and neither surgery or tumor size affected the AChE activity (p>0.05). FRAP levels before surgery were significantly lower (p<0.05) compared to control animals. Also, FRAP levels increased significantly after surgery in animals of the group A compared to data before surgery, a fact not observed in dogs from the group B. E-cadherin showed low significant positive correlation with FRAP levels (r=0.37, p-value=0.05); COX-2 showed a moderate significant positive correlation to FRAP (r=0.55, p-value<0.05); and COX-2 showed a low significant positive correlation to AChE (r=0.32, p-value=0.01). Conclusions. AChE and antioxidant levels are modified in dogs with mammary cancer. These variables are involved in various physiological functions, and thus, they might be related to disease pathogenesis.

RESUMEN Objetivo. Evaluar la actividad de la AChE en sangre total y los niveles de FRAP en muestras de perros con tumores mamarios antes y después de la cirugía, así como la relación entre estas variables con marcadores inmunohistoquímicos de tumores (E-caderina, ki-67 , COX - 2). Materiales y métodos. En este estudio, 13 perros con tumores mamarios se dividieron en dos grupos (A y B). El grupo A estaba formado por perros con tumores menores de 3 cm de diámetro y el grupo B estaba formado por perros con tumor de 3 cm de diámetro o más. La actividad de AChE y los niveles de FRAP se evaluaron antes y después de la cirugía y la inmunohistoquímica se realizó en los tumores. Resultados. La actividad de la AChE aumentó significativamente (p<0.05) en perros con cáncer mamario en comparación con los animales control, y ni la cirugía ni el tamaño tumoral afectaron la actividad de la AChE (p>0.05). Los niveles de FRAP antes de la cirugía fueron significativamente más bajos (p<0.05) en comparación con los animales control. Además, los niveles de FRAP aumentaron significativamente después de la cirugía en animales del grupo A en comparación con los datos antes de la cirugía, hecho que no se observó en perros del grupo B. La E-cadherina mostró correlación positiva baja con los niveles de FRAP (r = 0.37, valor p=0.05); COX-2 mostró una moderada correlación positiva significativa con FRAP (r = 0.55, p-valor<0.05); Y la COX-2 mostró una correlación positiva de baja significación con la AChE (r = 0.32, p-valor = 0.01). Conclusiones. AChE y los niveles de antioxidantes se modifican en perros con cáncer de mama. Estas variables están implicadas en diversas funciones fisiológicas, y por lo tanto, pueden estar relacionadas con la patogénesis de la enfermedad.

Biodigestores como tecnologia social para promoção da saúde: Estudo de caso para saneamento residencial em áreas periféricas / Biodigesters as social technology for health promotion: Case study for residential sanitation in peripheral áreas

Esse artigo relaciona o panorama do saneamento no Brasil com enfoque no reaproveitamento dos resíduos orgânicos e do esgoto sanitário, através de modelos de saneamento ecológico, com intuito de promover a saúde. O biodigestor é um exemplo de tecnologia social que possibilita sanear e obter energia em forma de gás natural através da biodigestão anaeróbia para áreas rurais e periurbanas. No estudo, o biodigestor foi classificado entre sua aplicabilidade: rurais, industriais e residenciais. No entanto, no contexto brasileiro, as residências provenientes de ocupação desordenada e áreas rurais, geralmente, não possuem tratamento de esgoto adequado. Assim, foram levantados dados sobre diferentes modelos de biodigestores, através de estudo de caso dos sistemas biodigestores do Vale Encantado e Águas do Imperador. Foi dado foco aos biodigestores residenciais, como tecnologias sociais, a partir de estudo de caso da comunidade do Vale Encantado. Para a construção deste estudo, a metodologia foi: Revisão Bibliográfica, Revisão Documental, Pesquisa Qualitativa, Estudo de caso e Observação Participante com saída de campo. Pode-se demonstrar que é possível solucionar de forma descentralizada a disposição final dos resíduos orgânicos e esgoto doméstico, para 20 pessoas, com aplicação em um restaurante comunitário ( Vale Encantado), e para aproximadamente 3.000 pessoas, com aplicabilidade em uma comunidade ou área periurbana (Águas do Imperador). Conclui-se que os biodigestores são uma alternativa de tecnologia social para o saneamento, principalmente em regiões onde soluções convencionais não são uma possibilidade financeiramente viável. (AU)

(This article relates the panorama of sanitation in Brazil with a focus on the reuse of organic waste and sanitary sewage, through ecological sanitation models, in order to promote health. The biodigester is an example of social technology that makes it possible to sanitize and obtain energy in the form of natural gas through anaerobic biodigestion to rural and peri-urban areas. In the study, biodigester was classified among its applicability: rural, industrial and residential. However, in the Brazilian context, residences coming from disordered occupation and rural areas generally do not have adequate sewage treatment. Thus, data were collected on different models of biodigesters, through a case study of the biodigesters systems of Vale Encantado and Águas do Imperador. A focus was given to residential biodigesters, such as social technologies, based on a case study of the Vale Encantado community. For the construction of this study, the methodology was: Bibliographic Review, Documentary Review, Qualitative Research, Case Study and Participant Observation with field output. I t can be demonstrated that it is possible to solve in a decentralized way the final disposal of organic waste and domestic sewage, for 20 people, with application in a community restaurant (Vale Encantado), and for approximately 3,000 people, applicable in a community or peri-urban area (Waters of the Emperor). It is concluded that biodigesters are a social technology alternative for sanitation, especially in regions where conventional solutions are not a financially viable possibility. (AU)

Insecticidal and repellent effect of cinnamon oil on flies associated with livestock / Efecto insecticida y repelente del aceite de canela sobre moscas asociadas con el ganado

Abstract Objective. Due to the increased parasitic resistance, there is a need to explore alternative insecticides, including natural products, such essential oils. In this sense, the aim of this study was to evaluate, for the first time, the insecticidal and repellent effect of Cinnamomun zeylanicum (free and nanoemulsion forms) in vitro and in vivo. Materials and methods. For that, the insecticidal effect of the free form was tested at 1.0, 5.0 and 10%, while the nanoemulsion form was tested at 0.5, 1.0 and 5.0% against adult house flies, Musca domestica. For validation of the test, the flies were sprayed with the diluent (water and triton 10%) and with blank nanoemulsion (without C. zeylanicum essential oil). Moreover, in vivo test was performed using cows naturally infested with Haemotobia irritans. Results. The results demonstrated that cinnamon oil (10%) and the nanoemulsion (5%) were 100% effective against M. domestica after 90 minutes of exposure. The repellent effect was tested in vivo using 5% of cinnamon oil on Holstein cows naturally infested by Haemotobia irritans. The flies were counted at 0, 1, 2, 3, 9 and 24 h after cinnamon oil treatment. It was verified significant decrease (p<0.05) in the number of flies on cows sprayed with cinnamon in all times. Conclusions. Based on these results, C. zeylanicum showed insecticidal effect (in vitro) against domestic flies and repellent effect (in vivo) against the horn fly.

Resumen Objetivo. Debido a la mayor resistencia parásita, hay una necesidad de explorar insecticidas alternativos, incluidos los productos naturales, tales como aceites esenciales. En este sentido, el objetivo de este estudio fue evaluar, para el primer equipo, el efecto insecticida y repelente de Cinnamomum zeylanicum (formas libres y nanoemulsión) in vitro e in vivo. Materiales y métodos. Para ello, el efecto insecticida de la forma libre se ensayó a 1.0, 5.0 y 10%, mientras que la forma nanoemulsión se ensayó a 0.5, 1.0 y 5.0% frente a las moscas domésticas adultas, Musca domestica. Para la validación de la prueba, las moscas fueron rociados con el diluyente (agua y triton 10%) y con nanoemulsión en blanco (sin aceite esencial de C. zeylanicum). También, fueron realizados pruebas in vivo usando vacas naturalmente infestadas con Haemotobia irritans. Resultados. Los resultados demostraron que el aceite de canela (10%) y la nanoemulsión (5%) fueron 100% eficaz contra M. domestica después de 90 minutos de exposición. El efecto repelente se ensayó in vivo usando 5% de aceite de canela en vacas Holstein, naturalmente infestados por Haemotobia irritans. Se contaron las moscas a las 0, 1, 2, 3, 9 y 24 h después del tratamiento el aceite de canela. Se verificó disminución significativa (p<0.05) en el número de moscas vivas de vacas canela pulverizada en todo momento. Conclusiones. En base a estos resultados, C. zeylanicum mostró un efecto insecticida (in vitro) contra las moscas domésticas y efecto repelente (in vivo) contra la mosca de los cuernos.

Detection of Staphylococcus aureus, Streptococcus agalactiae and Escherichia coli in Brazilian mastitic milk goats by multiplex-PCR / Detecção de Staphylococcus aureus, Streptococcus agalactiae e Escherichia coli em leite caprino mastítico no Brasil, por multiplex-PCR

This study evalueted the prevalence of Staphylococcus aureus, Streptococcus agalactiae and Escherichia coli in milk samples from 257 goats (513 half-udders) and ten bulk tanks, from ten dairy goat farms of São Paulo State, Brazil, by multiplex-PCR. The samples were screened by microbiological culture (gold-standard), and tested by different multiplex-PCR protocols for the detection of each bacterium. A total of 178 half-udders resulted positive by microbiological culture, with coagulase-negative staphylococci (70%), S. aureus (13.5%), S. intermedius (7.9%), and Enterobacteriaceae (4%) the prevalent pathogens. In other way, multiplex-PCR detected 173 pathogens in 151/523 (28.9%; CI95% 25.2-32.9%) milk samples 144/513 (28.1%) half-udders and 7/10 (70%) bulk tanks, with E. coli (86/162, 51.9%) and S. aureus (50/162, 30.9%) the prevalent ones in half-udders, and S. aureus (6/10, 60%) and E. coli (4/5, 36.4%) in bulk tanks. Multiplex-PCR showed a high performance for the detection of three bacteria at a time in mastitic goat milk direct from half-udders or bulk tanks. Thus, this multiplex-PCR protocol proved to be an adequate tool for the identification of the most common mastitis pathogens, independent of their phenotypic characteristics in the diagnosis of clinical mastitis in goats, allowing a continuous and better vigilance and monitoring the herd, being included in quality programs.(AU)

Este estudo avaliou por multiplex-PCR a prevalência de Staphylococcus aureus, Streptococcus agalactiae e Escherichia coli em amostras de leite de 257 caprinos (513 tetos) e dez tanques de expansão, em dez fazendas leiteiras do estado de São Paulo, Brasil. As amostras foram triadas por cultura microbiológica (padrão-uro) e testadas por diferentes protocolos multiplex-PCR para a detecção de cada bactéria. Um total de 178 amostras de leite foram positivos na cultura microbiológica, com estafilococos coagulase-negativos (70%), S. aureus (13,5%), S. intermedius (7,9%) e Enterobacteriaceae (4%) como patógenos prevalentes. Por outro lado, a PCR multiplex detectou 173 patógenos em 151/523 (28,9%, IC95% 25,2-32,9%) amostras de leite, 144/513 (28,1%) amostras de tetos e 7/10 (70%) em tanques de expansão, E. coli (86/162, 51,9%) e S. aureus (50/162, 30,9%) foram identificados nas amostras de tetos e S. aureus (6/10, 60%) e E. coli (4/5, 36,4%) em tanques expansão. Multiplex-PCR mostrou um alto desempenho para a detecção das três bactérias em leite de cabra com mastite ou em tanques de expansão. Dessa forma, este protocolo multiplex-PCR provou ser uma ferramenta adequada para a identificação dos patógenos mais comuns da mastite, independentemente de suas características fenotípicas no diagnóstico de mastite clínica em caprinos, permitindo uma vigilância contínua e melhor acompanhamento do rebanho, sendo incluído em programas de qualidade.(AU)

Injectable diphenyl diselenide supplementation in dairy sheep / Suplemento de difenil diselenuro inyectable en ovejas lecheras

ABSTRACT Objective. The aim of this study was to evaluate the influence of subcutaneous supplementation with diphenyl diselenide ((PhSe)2) in dairy sheep infected with gastrointestinal nematodes on animal health and possible damage to environment when the feces of these animals will be used for fertilizing. Materials and methods. The experiment was performed using 16 primipara dairy sheep, that were divided into two groups: the group A as control and the group B supplemented with 3 µmol/kg of (PhSe)2 subcutaneously. Blood samples were used to determine the hepatic function, as well as the protein and lipid metabolism in animals. Feces were used to determine the number of helminths eggs per gram of feces (EPG), as well as used for ecotoxicology tests. Results. The (PhSe)2 supplementation not affected the helminths reproduction, since the EPG did not differ (p>0.05) between groups. Total protein and globulin levels increase (p<0.05) in supplemented animals, while the seric alanine aminotransferase (ALT) levels decrease (p<0.05) in the end of experimental design. Cholesterol levels increase (p<0.05) in the supplemented animals, while triglycerides, albumin and urea not differ between groups (p>0.05). The feces of supplemented sheep not interfered the springtails reproduction. Conclusions. At the administered dose, the (PhSe)2 is not able to control the parasitism, however, it did increase the globulins and cholesterol levels, that are important to immune response and for sheep reproduction, respectively. Also, the feces of supplemented animals with (PhSe)2 can be used as organic fertilizing, without negative impacts to environment.

RESUMEN Objetivo. El objetivo de este estudio fue evaluar la influencia de la suplementación subcutánea con diselenuro de difenilo (PhSe)2 en ovejas lecheras infectadas con nematodos sobre la salud animal y posible daño al ambiente cuando las heces de estos animales se utilicen para fertilizar. Materiales y métodos. El experimento se realizó utilizando 16 ovejas lecheras, que se dividieron en dos grupos: el grupo A se usó como control y el grupo B se suplementó con 3 µmol/kg of (PhSe)2 vía subcutánea. Se utilizaron muestras de sangre para determinar la función hepática, así como el metabolismo de proteínas y lípidos en animales. Las heces se utilizaron para determinar el número de huevos por gramo de heces (EPG), así como para las pruebas de ecotoxicología. Resultados . La suplementación (PhSe)2 no afectó la reproducción de helmintos. Los niveles totales de proteína y globulina aumentan (p<0.05) en los animales suplementados, mientras que los niveles séricos de alanina aminotransferasa (ALT) disminuyen (p<0.05) al final del diseño experimental. Los niveles de colesterol aumentan (p<0.05) en los animales suplementados, mientras que los triglicéridos, la albúmina y la urea no difieren entre los grupos (p>0.05). Las heces de ovejas suplementadas no interferían en la reproducción de las colas de caballo. Conclusiones. A la dosis administrada, el (PhSe)2 no es capaz de controlar el parasitismo; sin embargo, aumenta los niveles de globulinas y colesterol, que son importantes para la respuesta inmune y para la reproducción, respectivamente. Las heces de animales suplementados pueden usarse como fertilizantes orgánicos, sin impactos negativos en ambiente.

Hematological findings and factors associated with feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) positivity in cats from southern Brazil / Achados hematológicos e fatores associados a positividade pelo vírus da leucemia felina (felv) e vírus da imunodeficiência felina em gatos do sul do Brasil

Using a retrospective study, 493 cats tested for FeLV and FIV were selected for analysis of the association between hematologic findings and positivity at immunoassay test. Individual and hematologic variables were assessed considering the influence of results using univariate and multivariate logistic regression analysis. Out 153 of the 493 cats were positive for FeLV (31%), 50 were positive for FIV (10.1%) and 22 were positive for both FIV and FeLV (4.4%). Multivariate analysis detected significant associations between FeLV infection and age below 1 year (p=0.01), age from 1 to 10 years (p=0.03), and crossbreed (p=0.04). Male cats were more likely to be FIV-positive (p=0.002). Regarding hematological changes, FeLV-positive cats have higher odds to anemia, leukopenia and lymphopenia than FeLV-negative cats. FIV-positive cats are more likely to have anemia than negative. Identification of associated factors related to animal status and correlation of hematological disorders with infection by retroviruses in cats could be useful for detecting these retroviral diseases in cats.(AU)

Através de um estudo retrospectivo, 493 gatos testados para FeLV e FIV foram selecionados para análise da associação entre as alterações hematológicas e a positividade no teste imunoenzimático. Variáveis individuais e hematológicas foram consideradas para verificar a influência dos resultados utilizando análise de regressão logística univariada e multivariada. Um total de 153 de 493 gatos avaliados foram positivos para o FeLV (31%), 50 foram positivos para o FIV (10,1%) e 22 foram positivos para FIV e FeLV (4,4%). Análise multivariada detectou uma associação significativa entre a infecção pelo FeLV e a idade abaixo de 1 ano (P=0,01), idade entre 1 a 10 anos (P=0,03) e raça mista (P=0,04). Gatos machos foram mais predispostos a serem positivos para FIV (P=0,002). Com base nas alterações hematológicas, gatos positivos para o FeLV tem maior odds para apresentar anemia, leucopenia e linfopenia que os negativos. Gatos positivos para FIV possuem maiores chances de apresentarem anemia que os gatos negativos. A identificação dos fatores associados à infecção relacionados ao perfil do animal e a correlação com os distúrbios hematológicos com a infecção, pode ser útil para detecção das doenças retrovirais em gatos.(AU)

Fatores relacionados a problemas de comportamento em gatos / Factors associated with behavior problems in cats

Os problemas de comportamento apresentam importância não só no bem estar animal e na qualidade da relação humana-animal como também em saúde publica. Problemas de comportamento são uma das principais razões de abandono e subsequentemente o destino destes animais são abrigos ou até mesmo eutanásia. Além disso, a agressividade é um fator de risco para transmissão de zoonoses. Com o objetivo de avaliar a frequência de fatores relacionados a problemas de comportamento em gatos, foram coletadas informações de 229 gatos através de um questionário aplicado em tutores que aguardavam atendimento no Hospital de Clínicas Veterinária da Universidade Federal do Rio Grande do Sul (HCV-UFRGS). Dentre os comportamentos arranhadura em móveis foi o problema comportamental mais frequente (65,1%- IC 95%: 58,5-71,4%) seguido de agressividade (61,3%- IC 95%: 54,2-67,1%), eliminação inapropriada (37,1%- IC 95%: 31,3-42,1%) e vocalização excessiva (23,6%- IC 95%: 20,1-29,8%). Os dados foram analisados por regressão logística com uma função de ligação logit. De acordo com a análise univariada, a presença de um arranhador teve uma relação significativa protetiva, podendo contribuir para a redução do comportamento de arranhar móveis (risco relativo [RR]=0.31- IC 95%:0.19 - 0.53). Fêmeas e gatos assustados foram identificados com maior dificuldade de ter uma relação amigável com outros gatos RR=3.56 (IC 95%:1.78 - 7.11), RR=2.84( IC 95%:1.60 - 5.04) respectivamente também quanto maior o número de gatos na residência, maiores as chances de haver eliminação inapropriada. Os gatos castrados antes da puberdade apresentaram menos chances de desenvolver eliminação inapropriada RR=0.43 (IC 95%:0.21-0.88) e, finalmente, a vocalização excessiva foi relacionada com busca de atenção RR=2.62 (IC 95%:1.54 - 4.45). Os resultados desse estudo podem ajudar a prevenir problemas comportamentais em felinos domésticos.(AU)

Behavioral problems have importance not only in animal welfare and the quality of human-animal relationship, but also in public health. Behavior problems are a major reason of abandonment and subsequently the fate of these animals are shelters or even euthanasia. Furthermore, the aggressiveness is a risk factor for zoonoses transmission. In order to assess the frequency of factors related to behavior problems, information from 229 cats were collected through a questionnaire applied to tutors awaiting for care in clinics in Veterinary Hospital of the Federal University of Rio Grande do Sul (HCV-UFRGS). Among the behaviors scratch furniture was the most common problem (65.1% - CI95%: 58.5 to 71.4%), followed by aggressiveness (61.3% - CI95%: 54.2 to 67, 1%), inappropriate elimination (37.1% - 9 CI95%: 31.3 to 42.1%) and excessive vocalization (23.6% - CI95%: 20.1 to 29.8%). Data were analyzed by logistic regression with a logit link function. Univariate analysis identified the presence of scratching as significant protective factor, that may contribute to the reduction of scratching furniture (Relative risk [RR] = 0.31- CI95%: 0:19 to 0:53). Females and frightened cats were identified as having more difficulty were for friendly relationship with other cats RR = 3.56 (CI95%: 1.78-7.11), RR = 2.84 (95% CI: 1.60-5.04) respectively; also the higher the number of cats in a residence, the greater the chance for inappropriate elimination. Neutered cats before puberty had less chance of developing inappropriate elimination RR = 0:43 (CI95%: 0.21-0.88), and finally, excessive vocalization was related to obtain tutor attention RR = 2.62 (CI95%: 1:54 to 4:45). The results of this study may help prevent behavioral problems in domestic cats.(AU)

Caracterização anatomopatológica e bacteriológica em frangos de corte condenados totalmente por colibacilose sob Serviço de Inspeção Federal / Pathological and bacteriological characterization on broilers totally condemned due to colibacillosis under the control of the Federal Inspection Service

A colibacilose é a principal causa infecciosa de condenação total de carcaça em frangos de corte no sul do Brasil. Esse trabalho tem por objetivo determinar o grau de concordância entre a condenação total por colibacilose de frangos de corte abatidos em estabelecimento sob Serviço de Inspeção Federal (SIF) com o diagnóstico anatomopatológico e bacteriológico. O estudo foi realizado com 45 frangos de corte condenados totalmente por colibacilose (caso) e seus respectivos 45 controles (frangos sem lesões). Em todos os frangos condenados pelo SIF havia lesões macroscópicas e, nos controles não se observou. Através do teste Kappa-Cohen´s essas duas variáveis apresentaram concordância quase perfeita. As aves condenadas apresentaram lesões em fígado (27/45); em fígado e sacos aéreos (11/45); em fígado e coração (2/45); fígado, sacos aéreos e coração (2/45); fígado, sacos aéreos e oviduto (1/45); fígado, sacos aéreos, coração e tecido subcutâneo (1/45); e fígado, sacos aéreos, oviduto e baço (1/45). Observou-se concordância quase perfeita entre condenação e lesão hepática. Histologicamente, em 41 casos e 12 controles observaram-se lesões, sendo os mais frequentes hepatite necrosante aleatória, bronquite fibrino-heterofílica, pericardite aguda e traqueíte linfoplasmocitária. Nas aves com hepatite identificou-se E. coli, Enterococcus sp. e Streptococcus sp. (10/38) e, nas aves com bronquite ou broncopneumonia isolou-se Escherichia coli e Staphylococcus coagulase positiva (9/14). O PCR em tempo real e a imuno-histoquímica para Mycoplasma gallisepticum e M. synoviae foram negativos. Nos casos de condenação total por colibacilose o fígado foi o principal órgão acometido, portanto, o critério de condenação deveria ser revisto, sugerindo condenação por hepatite nesses casos, já que outras bactérias podem causar hepatite, como foi demonstrado nesse estudo.(AU)

Colibacillosis is the main infectious cause of total carcass condemnation in broilers in southern Brazil. This study aims to determine the degree of agreement between the total carcass condemnation for colibacillosis in broilers slaughtered in establishments under Federal Inspection Service (SIF) with the pathological and bacteriological diagnosis. The study was conducted with 45 broilers totally condemned by colibacillosis (case) and theirs 45 respective controls (chickens without lesions). All broilers condemned had gross lesions and the controls had not. The Kappa-Cohen's test showed that these two variables had almost perfect agreement. Broilers condemned showed lesions in liver (27/45); liver and air sacs (11/45); liver and heart (2/45); liver, heart and air sacs (2/45); liver, air sacs and oviduct (1/45); liver, air sacs, heart and subcutaneous (1/45); and liver, air sacs, oviduct and spleen (1/45). There is almost perfect agreement between carcass condemnation and liver damage. Histologically, in 41 cases and 12 controls were observed lesions, the most frequent diagnoses were random necrotizing hepatitis, fibrinous-heterophilic bronchitis, acute pericarditis and lymphoplasmacytic tracheitis. In hepatitis cases was isolated Escherichia coli, Enterococcus sp. and Streptococcus sp. (10/38) and in bronchitis or bronchopneumonia E. coli and coagulase positive Staphylococcus (9/14). The polymerse chain reaction (PCR) and immunohistochemistry (IHC) tests for Mycoplasma gallisepticum and M. synoviae were negative. In cases of total carcass condemnation by Colibacillosis the liver was the main organ affected. Therefore, the condemnation criteria should be revised, suggesting conviction for hepatitis in these cases, because other bacteria can cause hepatitis, as demonstrated in this study.(AU)

Gastrointestinal protozoa in dairy calves: identification of risk factors for infection / Protozoos gastrointestinales en terneros lecheros: identificación de factores de riesgo para la infección

ABSTRACT Objective. This study aimed to evaluate the occurrence of gastrointestinal protozoa in dairy calves and to identify potential risk factors for this type of infection. Materials and methods. For this purpose, 243 fecal samples were collected from calves up to 60 days of age in 43 dairy farms located in the West region of Santa Catarina state, Brazil. Samples were examined by centrifugal-flotation technique. Results. As a result, Giardia was present in 26.75% (65/243) of all samples, Eimeria in 21.81% (53/243), and Cryptosporidium in 20.99% (51/243). Additionally, 46.50% (113/243) of the samples were negative for any protozoa, while 39.10% (95/243) and 14.40% (35/208) showed single and mixed infections, respectively. There was a higher association between Cryptosporidium and Giardia (6.99%) in cases of mixed infections. However, the triple protozoa association had the lowest prevalence in mixed infections (2.06%). Epidemiologically, a questionnaire was applied to determine risk factors for these parasitic infections. Based on the statistical model applied, some risk factors for Cryptosporidium infections were identified, highlighting feeding management, period of time that calves stayed with their mothers (cows), and contact with dogs; the risk of contracting Giardia increased according to the milk source, while the floor type bedding, and age were appointed as risks factors for Eimeria. Conclusions. Therefore, it is possible to confirm that Giardia, Cryptosporidium and Eimeria may infect dairy calves, and the knowledge of some risk factors associated to their infection in calves.

Se recogieron 243 muestras de heces de terneros de hasta 60 días de edad en 43 granjas lecheras ubicadas en la región del oeste del estado de Santa Catarina, Brasil. Las muestras fueron examinadas por la técnica de centrifugación-flotación. Resultados. Como resultado, Giardia estaba presente en 26.75% (65/243) de todas las muestras, Eimeria en 21.81% (53/243), y Cryptosporidium en 20.99% (51/243). Además, 46.50% (113/243) de las muestras fueron negativas para cualquier protozoos, mientras que 39.10% (95/243) y 14.40% (35/208) mostraron infecciones simples y mixtas, respectivamente. Hubo una mayor asociación entre Cryptosporidium y Giardia (6.99%) en los casos de infecciones mixtas. Sin embargo, la asociación de triple protozoos tenía la menor prevalencia de infecciones mixtas (2.06%). Epidemiológicamente, se aplicó un cuestionario para determinar los factores de riesgo para estas infecciones parasitarias. Se han identificado algunos factores de riesgo de infecciones por Cryptosporidium, destacando manejo de la alimentación, periodo de tiempo que los terneros permanecieron con sus madres (vacas), y el contacto con los perros; el riesgo de contraer Giardia incrementado en función de la fuente de la leche, mientras que el tipo de suelo de las camas, y la edad fueron nombrados como los riesgos de factores de Eimeria. Conclusiones. Es posible confirmar que Giardia, Cryptosporidium y Eimeria pueden infectar a terneros lecheros, y el conocimiento de algunos factores de riesgo asociados a la infección en terneros.

Effect of stocking rate and floor types on performance, skin temperature and leukogram in pigs raising / Efecto de la carga animal y el tipo de piso sobre el rendimiento, la temperatura de la piel y leucograma en la cría de cerdos

ABSTRACT Objective. The aim of this study was to evaluate the performance, thermoregulatory characteristics and the leukogram of growing finishing pigs reared in different stocking rates kept on compact floor pens or with shallow pool pens. Material and methods. Thirty-six pigs were used in two steps (total of 72 animals were used). In the first step it was analysed performance pig (daily feed intake, weight gain and feed: gain ratio) and backfat thickness (P2). In the second step, the same analyzes were repeated, in addition, analysis of leukogram and skin temperature was performed in P2 and anal region, at the end of growing and finishing phase. Results. It was evaluated for differences between treatments and stocking. It was not found effect of floor type on growing phase, but the use of shallow pool had a negative effect on the gain and feed: gain ratio in the finishing phase, as well as lower surface temperature in the anal region on treatment with shallow pool in the finishing phase. No effect of treatments and type of floor on pig leukogram. Allowing more space/animal decreased backfat thickness. The use of shallow pool affected negatively the performance in the finishing phase. Conclusions. The shallow pool uses impair the finishing pig performance, despite improving thermolysis, with no effect observed on cell immune response.

RESUMEN Objetivo. El objetivo de este estudio fue evaluar el rendimiento, las características de termorregulación, y el leucograma de cerdos de engorde, criados en diferentes densidad mantenidos en corrales de piso compactos o corrales con lámina de agua. Material y métodos. Treinta y seis cerdos se utilizaron en dos etapas (un total de 72 animales utilizados). En el primer paso, se analizaron las características zootécnicas (consumo diario de alimento, ganancia de peso y la conversión alimenticia) y el espesor de grasa dorsal (P2). En el segundo paso, los mismos análisis se repitieron, además, el análisis de leucograma y temperatura de la piel se realizó en P2 y la región anal, al final de la recría y terminación. Resultados. Se evaluaron las diferencias entre los tratamientos. No se encontró efecto del tipo de corrales en fase de recría, pero el uso de los corrales con lámina de agua tuvo un efecto negativo sobre la ganancia y conversión alimenticia en la fase de terminación, así como una menor temperatura de la superficie en la región anal en el tratamiento con lámina de agua en la fase de terminación. No hubo efecto de los tratamientos y tipo de corales sobre el Leucograma de los cerdos. Permitiendo más espacio/animal disminuyó el espesor de grasa dorsal. El uso de la lámina de agua afectó negativamente al rendimiento en la fase de terminación. Conclusiones. El uso de lámina de agua afectó el rendimiento de los cerdos de terminación, a pesar de la mejora de termólisis, sin efecto visible en la respuesta inmune celular.

Homicídio conjugal na grande São Paulo e na grande Florianópolis: notícias publicadas em jornais / Partner homicide in the greater São Paulo and greater Florianópolis: news published in newspapers

Homicídio conjugal é o termo adotado ao gesto homicida que ocorre entre pessoas que estão, ou estiveram, vinculadas por uma relação afetiva. No Brasil, não existe um levantamento sistemático dos casos de homicídio conjugal, o que torna as fontes jornalísticas um importante meio de conhecimento dos casos. Objetiva-se uma discussão do homicídio conjugal por meio dos casos reportados em dois importantes jornais (O Estado de São Paulo e Diário Catarinense), entre os anos de 2000 e 2010. Encontrou-se um total de 34 casos ocorridos na Grande Florianópolis e 110 casos na Grande São Paulo. Em relação ao número de casos registrados em cada região, os dados indicam, proporcionalmente, uma maior incidência desse tipo de crime na Grande Florianópolis, em Santa Catarina. Concluiu-se, com os casos, a prevalência do gesto homicida perpetrado por homens, a presença de indícios precursores, o impacto da separação e a presença de violência conjugal

Partner Homicide is the adopted term to the homicide gesture between people within a current or former relationship. There is not any methodical survey of Conjugal Homicide in Brazil, making journalistic sources the most reliable data. This article aims a discussion on Conjugal Homicide taking reported cases in two widely spread newspapers (O Estado de São Paulo e Diário Catarinense) in a ten-year span (2000-2010). A total of 34 cases in Greater Florianópolis and 110 cases in Greater São Paulo were found. When comparing the registered cases, there was a greater proportional incidence in the Greater Florianópolis. It was concluded by the surveyed cases that were a prevalence of male homicide gesture; precursor symptons; couple's split impact and the presence of intimate terrorism or domestic violence
