Ameloblastic fibro-odontoma : a conservative surgical approach

Ameloblastic fibro-odontoma (AFO) is a rare benign mixed odontogenic tumor that occurs predominantly in children and young adults with no gender predilection and anatomic site, usually appearing as a painless swelling. We present a case of an 11-year-old non-Caucasian boy complaining of large painless isolated swelling in the right mandibular body. Intraoral examination revealed a tumoral mass with cortical bone expansion, covered by normal mucosa measuring 4.0 x 2.0 cm, located on both the lingual and buccal surfaces of the right body of the mandible, with displacement of the neighboring teeth. Panoramic radiography revealed an expansile, radiolucent and well circumscribed lesion with scattered foci of calcified material, which contained several radiopaque bodies of varying sizes and shapes. The provisional diagnoses were odontoma or AFO/ Biopsy confirmed AFO. The patient was treated with conservative surgery. After two years of follow-up, no alteration or recurrence was detected

Effectiveness of low flow vascular lesions sclerosis with monoetanolamine : report of six cases

Vascular malformations or even hemangiomas need therapeutic intervention if they start to cause clinical symptoms or personal discomfort. Different therapeutic modalities, including cryotherapy, corticosteroids, laser therapy, sclerotherapy, surgery, and/or embolization, can be performed successfully. Sclerotherapy with monoethanolamine is a relatively simple and effective method to treat low flow vascular lesions. We presented a report of six cases of vascular malformations treated with monoethanolamine. There were 3 male and 3 female patients, with an age range of 20 to 68 years. The patients were submitted to applications according to clinical response and/or tolerability. In all cases, low-flow vascular lesions were recorded and submitted to infiltration with 2.5% monoethanolamine, directly into the lesions. The volume applied was approximately the middle of affected area. Vascular lesions were characterized as low-flow due to absence of arterial pulsation and flat consistence. The sclerosis with 2.5% monoethanolamine resulted in complete or partial involution, without severe complications

Silagem ácida e biológica de resíduos de peixes produzidos na Amazônia ocidental – Acre / Acid and biological silage of fish residues produced in the western Amazon - Acre

Existem uma grande quantidade de resíduos gerados pelas indústrias beneficiadoras de pescado, sendo o seu descarte um grande problema de poluição ambiental. Uma alternativa é transformar esses resíduos em silagem, possibilitando a bioconversão do material, trazendo vantagens econômicas para a indústria, além de permitir o manejo do resíduo. O estudo teve por objetivo elaborar e avaliar o valor nutritivo das silagens ácida e biológica de resíduos de Pintado e Pirapitinga, as silagens foram preparadas mediante a moagem dos resíduos e adicionados 10% de ácido acético para silagem ácida, e 6% de iogurte natural e 10% de açúcar comercial para biológica. Foram armazenadas em baldes em temperatura ambiente durante 45 dias. O pH e temperatura foram monitorados em dias intercalados. Foram realizadas análises microbiológicas para fungos e leveduras, microrganismos mesófilos totais e coliformes totais a 35°C. Os dados foram submetidos à análise de variância e comparadas pelo teste de Tukey a nível de 5% de probabilidade. As silagens ácidas apresentaram os menores níveis de pH em média de 3,96 (Pintado) e 3,71 (Pirapitinga). Nas análises microbiológicas observou a ausência de coliformes totais a 35°C, fungos e leveduras, microrganismos mesofilos totais. As análises revelaram diferenças significativas entre as silagens sendo os valores expressivos para proteína bruta na silagem biológica de Pintado (42,13%) e Pirapitinga (42,92%), e energia bruta na silagem biológica de Pintado (3907 Kcal/Kg) e Pirapitinga (3776 Kcal/Kg) e que evidenciaria de forma mais desejável a relação Proteína/Energia gerando um produto de qualidade com potencial para uma possível formulação de ração. 

Clinical and microbiological characteristics of patients colonized or infected by Stenotrophomonas maltophilia: is resistance to sulfamethoxazole/trimethoprim a problem?

Stenotrophomonas maltophilia has emerged as an important opportunistic pathogen in the last decade. Increased resistance to sulfamethoxazole/trimethoprim (SMX/TMP) has been reported in S. maltophilia strains in the past few years, leading to few therapeutic options. We conducted a prospective multicenter study at two Brazilian teaching hospitals that identified S. maltophilia isolates and evaluated their antimicrobial susceptibility profile, SMX/TMP resistance genes and their clonality profile. A total of 106 non-repeated clinical samples of S. maltophilia were evaluated. Resistance to SMX/TMP was identified in 21.6% of the samples, and previous use of SMX/TMP occurred in 19 (82.6%). PCR detected the sul1 gene in 14 of 106 strains (13.2%). Of these isolates, nine displayed resistance to SMX/TMP. The resistant strains presented a polyclonal profile. This opportunistic pathogen has emerged in immunocompromised hosts, with few therapeutic options, which is aggravated by the description of emerging resistance mechanisms, although with a polyclonal distribution profile

Primary care and vaccination: challenges and contributions for the Brazilian population

The present research delimited as objective to carry out an investigation on the challenges encountered by Primary Health Care and its Contributions with regard to vaccination for the control and immunization of the population. It is essential to consider contemporary narratives - national and international - that orbit around the central axis “Primary care and vaccination”, which consisted of: immunization; population management; quality of life; contributions; challenges and vaccine coverage, in a timeline from 2019 to 2022. As challenges, we deal with disinformation, or even fake news, which confuse the population, leading them to disbelieve in the vaccine potential. Finally, we analyze what have been the main contributions of primary care to improve the implementation of vaccine management. We resort to portals such as the World Health Organization (WHO), the Ministry of Health of Brazil and articles from the Vitrual Health Library to strengthen that, in Primary Health Care, vaccination services offer important evaluation indicators, which have been demonstrating, as over time, the contribution of vaccination actions to the health sector, characterizing them as one of the most rewarding, in view of the impact on disease control

Aves da Chapada dos Guimarães, Mato Grosso, Brasil: uma síntese histórica do conhecimento

Here we present a historical review of all known ornithological surveys carried out at Chapada dos Guimarães, central-western Brazil. We characterize the avifauna of the region following a critical review of all bird species listed by several generations of ornithologists. The final species account was produced based on extensive literature and museum consultation and on recent field work. Special attention is given to the series of papers by J.A. Allen, which was based on the monumental collecting work by H.H. Smith and his wife on the 19th century. The study area is predominantly characterized by a Cerrado bird assemblage and in a lesser extent, by Amazonian elements. A total of 393 bird species have confident records for the region. Other 52 species were cited for the region, but were judged unlikely to occur in the study area under our stringent criteria. Twenty four species collected by the Smiths are no longer recorded in the region. Six of these species are sensitive grassland specialists, and three are popular cagebirds. These species are probably extinct in the area. Seven species are waterbirds and two are Amazonian species, all of them have probably always been very rare in the region due to the lack of apropriate habitat. Six species are naturally rare, and could be overlooked. We report the first documented record of Caprimulgus longirostris for Mato Grosso and the second record of Pipraeidea melanonota for the state. We also comment on several apparently rare species on the region such as Ictinia mississipensis, Buteo melanoleucus, Harpia harpyja, Megascops usta, Asio flammeus, Berlepschia rikeri, Euscarthmus rufomarginatus, Xenopsaris albinucha, and Poospiza cinerea.É apresentada uma revisão histórica dos inventários ornitológicos conduzidos na Chapada dos Guimarães, centro-oeste do Brasil. A avifauna da região é caracterizada a partir de uma revisão crítica de todas as listas de espécies produzidas por várias gerações de ornitólogos, espécimes depositados em museus e meticulosos trabalhos de campo. Especial atenção foi dada às publicações de J.A. Allen, baseadas na monumental coleção preparada por H.H. Smith e sua esposa no final do século XIX. A avifauna da região é típica do Cerrado, abrigando também espécies amazônicas. Um total de 393 espécies de aves é listado para a região, sendo outras 52 espécies citadas pela literatura consideradas de ocorrência improvável baseado nos critérios restritivos adotados. Vinte e quatro espécies coletadas pelos Smith não foram mais registradas para a região. Seis destas espécies são campestres e bastante sensíveis a alterações antrópicas, enquanto que outras três são perseguidas pelo comércio ilegal de aves. Estas espécies provavelmente se encontram extintas na região. Sete outras espécies associadas a corpos hídricos, e duas de distribuição predominantemente Amazônica, eram provavelmente raras na região, mesmo em tempos históricos, principalmente devido à falta de hábitat adequado. Seis outras são normalmente raras, podendo ter passado despercebidas. São apresentados o primeiro registro documentado de Caprimulgus longirostris para o Mato Grosso e o segundo registro de Pipraeidea melanonota para o estado. Também são discutidos os registros de outras espécies raras na região, tais como Ictinia mississipensis, Buteo melanoleucus, Harpia harpyja, Megascops usta, Asio flammeus, Berlepschia rikeri, Euscarthmus rufomarginatus, Xenopsaris albinucha e Poospiza cinerea

COMPORTAMENTO DA PRESSÃO ARTERIAL E COMPOSIÇÃO CORPORAL APÓS DOIS TIPOS DE TREINAMENTOS PERIODIZADOS EM PARTICIPANTES COM SÍNDROME METABÓLICA. ENSAIO CLÍNICO CONTROLADO RANDOMIZADO

Os treinamentos aeróbio intervalado e resistido são utilizados na prevenção e tratamento da Síndrome Metabólica (SMet), porém há lacunas quanto às diferentes metodologias aplicadas. O objetivo foi analisar e comparar o comportamento da pressão arterial após treinamentos periodizado aeróbio e resistido em adultos com Síndrome Metabólica. Vinte e nove voluntários, sedentários de ambos os sexos, com idade entre 35 e 60 anos com SMet, foram aleatorizados em 3 grupos: treinamento aeróbio intervalado (TAI; n=9), treinamento resistido (TRC; n=11) e o grupo controle (n=9). O programa foi constituído por 3 sessões semanais durante 12 semanas. Antes e após o treinamento foi mensurada a pressão arterial em repouso. Houve diminuição da pressão arterial sistólica de 7mmHg no grupo TAI, sem significância estatística. Não foram observadas alterações na pressão arterial diastólica. Após ambos treinamentos periodizados não foram observados mudanças na pressão arterial em participantes com SMet

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
