Assessment of the Effects of Swimming as a Postoperative Rehabilitation on Nerve Regeneration of Wistar Rats Submitted to Grafting of Autologous Nerves after Injury to the Sciatic Nerve.

Objective To evaluate the effects of swimming on nerve regeneration after sciatic nerve injury in Wistar rats. Methods A total of 30 Wistar rats was divided into 3 groups: Sham + Nat group animals that were not submitted to graft surgery and were submitted to swimming ( n = 10); Graft group: animals submitted to autologous sciatic nerve graft ( n = 10); and Graft + Nat group: animals submitted to autologous sciatic nerve graft surgery and to swimming ( n = 10). The results were analyzed on the software (GraphPad Software, San Diego, CA, USA). Results In the first evaluation, all sciatic functional index (SFI) values were similar ( p = 0.609). Thirty days after the surgical procedure, we observed differences between all the comparisons: Sham + Nat (-34.64 ± 13.89) versus Graft (-145.9 ± 26.06); Sham + Nat versus Graft + Nat (-89.40 ± 7.501); Graft (-145.9 ± 26.06) versus Graft + Nat (-89.40 ± 7.501). In the measurements (60 and 90 days), there was no statistical difference between the Graft and Graft + Nat groups, with significantly lower values in relation to the control group ( p < 0.001). The number of motor neurons presented differences in the comparisons between the Sham + Nat and Graft groups (647.1 ± 16.42 versus 563.4 ± 8.07; p < 0.05), and between the Sham + Nat and Graft + Nat groups (647.1 ± 16.42 versus 558.8 ± 14.79; p < 0.05). There was no difference between the Graft and Graft + Nat groups. Conclusion Animals submitted to the swimming protocol after the sciatic nerve grafting procedure did not present differences in the SFI values and motor neuron numbers when compared to the control group. Therefore, this type of protocol is not efficient for the rehabilitation of peripheral nerve lesions that require grafting. Therefore, further studies are needed.

Resumo Objetivo Avaliar os efeitos da natação na regeneração nervosa após a lesão do nervo ciático em ratos Wistar. Métodos Um total de 30 ratos Wistar foram divididos em 3 grupos: grupo Sham + Nat: animais que não foram submetidos à cirurgia de enxerto e foram submetidos à natação (n = 10); grupo Enxerto: animais que foram submetidos à cirurgia de enxerto autólogo de nervo ciático (n = 10); e grupo Enx + Nat: animais submetidos à cirurgia de enxerto autólogo de nervo ciático e à natação (n = 10). Os resultados foram analisados pelo software GraphPad Prism 5.0 (GraphPad Software, San Diego, CA, EUA). Resultados Na primeira avaliação, todos os valores do índice funcional do ciático (IFC) foram semelhantes (p = 0.609). Após 30 dias do procedimento cirúrgico, foram observadas diferenças entre todas as comparações: Sham + Nat (−34,64 ± 13,89) versus Enxerto (−145,9 ± 26,06), grupos Sham + Nat versus Enx + Nat (−89,40 ± 7,501), grupos Enxerto (−145,9 ± 26,06) versus Enx + Nat (−89,40 ± 7,501). Nas medidas (60 e 90 dias), não houve diferença estatística entre os grupos Enxerto e Enx + Nat, com valores significativamente menores em relação ao grupo controle (p < 0,001). O número de motoneurônios apresentou diferenças nas comparações entre os grupos Sham + Nat e Enxerto (647,1 ± 16,42 versus 563,4 ± 8,07; p < 0,05) e Sham + Nat e Enx + Nat (647,1 ± 16,42 versus 558,8 ± 14,79; p < 0,05), não havendo diferença entre os grupos Enxerto e Enx + Nat. Conclusão Os animais submetidos ao protocolo de natação após o procedimento de enxerto do nervo ciático não apresentaram diferenças nos valores de IFC e nos números de motoneurônios quando comparados com grupo controle. Portanto, este tipo de protocolo não é eficiente para reabilitação de lesões nervosas periféricas que necessitam de enxerto, sendo necessários novos estudos.

Potential application of oil-suspended particulate matter aggregates (OSA) on the remediation of reflective beaches impacted by petroleum: a mesocosm simulation.

This paper presents the oil-suspended particulate matter aggregate (OSA) resulted from the interaction of droplets of dispersed oil in a water column and particulate matter. This structure reduces the adhesion of oil on solid surfaces, promotes dispersion, and may accelerate degradation processes. The effects of the addition of fine sediments (clay + silt) on the formation of OSA, their impact on the dispersion and degradation of the oil, and their potential use in recovering reflective sandy beaches were evaluated in a mesoscale simulation model. Two simulations were performed (21 days), in the absence and presence of fine sediments, with four units in each simulation using oil from the Recôncavo Basin. The results showed that the use of fine sediment increased the dispersion of the oil in the water column up to four times in relation to the sandy sediment. There was no evidence of the transport of hydrocarbons in bottom sediments associated with fine sediments that would have accelerated the dispersion and degradation rates of the oil. Most of the OSA that formed in this process remained in the water column, where the degradation processes were more effective. Over the 21 days of simulation, we observed a 40 % reduction on average of the levels of saturated hydrocarbons staining the surface oil.

Neuroparacoccidioidomycosis: Case Report and Literature Review

Introduction Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis, and it can compromise the central nervous system (CNS) in 10­27% of all cases. Case Report A 31-year-old man presented to the Emergency Department with headache, left-sided weakness, clonus at the ankle and a positive Babinski sign. Head computed tomography (CT) and magnetic resonance imaging (MRI) scans showed a 5.1 3.8 cm lobulated lesion with areas of liquefaction in the right centrum semiovale. Discussion Central nervous system PCM can mimic a brain tumor, and most cases are diagnosed by biopsy of the lesion. The treatment includes antibiotics, but some cases require surgery. Conclusion Due to high morbimortality rates, the diagnosis must be considered, and early treatment started in patients who live in rural regions endemic for PCM when a ring-enhancing mass associated with perilesional edema is observed on MRI scans.

Introdução Paracoccidioidomicose (PCM) é uma micose sistêmica causada pelo fungo Paracoccidioides brasiliensis e que pode comprometer o sistema nervoso central (SNC) em 10­27% dos casos. Relato de caso Um homem de 31 anos é admitido no pronto socorro com cefaleia, hemiparesia esquerda com clonus e presença de sinal de Babinski. As imagens da tomografia computadorizada (TC) de crânio e da ressonância nuclear magnética (RNM) demonstraram uma lesão de 5,1 3,8 cm no centro semioval direito de aspecto lobulado com áreas de liquefação no centro semioval direito. Discussão Paracoccidioidomicose do SNC pode simular um tumor cerebral, sendo a maioria dos casos diagnosticada por biopsia da lesão. O tratamento inclui antibióticos, mas alguns casos necessitam de abordagem cirúrgica. Conclusão Devido à alta morbimortalidade, o diagnóstico deve ser considerado e o tratamento precoce iniciado em pacientes que vivem em áreas rurais endêmicas para PCM e que apresentam lesão com captação anelar de contraste associada a edema perilesional nas imagens de RNM.

Text neck and neck pain in 18-21-year-old young adults.

PURPOSE: The aim of this study was to investigate whether there is an association between text neck and neck pain in young adults. METHODS: Observational cross-sectional study with 150 18-21-year-old young adults from a public high school in the state of Rio de Janeiro was performed. In the self-report questionnaire, the participants answered questions on sociodemographic factors, anthropometric factors, time spent texting or playing on a mobile phone, visual impairments, and concern with the body posture. The neck posture was assessed by participants' self-perception and physiotherapists' judgment during a mobile phone texting message task. The Young Spine Questionnaire was used to evaluate the neck pain. Four multivariate logistic regression models were fitted to investigate the association between neck posture during mobile phone texting and neck pain, considering potential confounding factors. RESULTS: There is no association between neck posture, assessed by self-perception, and neck pain (OR = 1.66, p = 0.29), nor between neck posture, assessed by physiotherapists' judgment, and neck pain (OR = 1.23, p = 0.61). There was also no association between neck posture, assessed by self-perception, and frequency of neck pain (OR = 2.19, p = 0.09), nor between neck posture, assessed by physiotherapists' judgment, and frequency of neck pain (OR = 1.17, p = 0.68). CONCLUSION: This study did not show an association between text neck and neck pain in 18-21-year-old young adults. The findings challenge the belief that neck posture during mobile phone texting is associated to the growing prevalence of neck pain.

Colon cancer surgery in patients operated on an emergency basis.

OBJECTIVE: to study the epidemiological profile of patients with colorectal cancer operated on an emergency basis at the Bonsucesso Federal Hospital. METHODS: this is a retrospective study of patients operated between January 1999 and December 2012. We analyzed the following variables: age, gender, clinical data, TMN staging, tumor location, survival and types of surgery. RESULTS: we evaluated 130 patients in the study period. The most frequent clinical picture was intestinal obstruction, in 78% of cases. Intestinal perforation was the surgical indication in 15%. The majority (39%) of the patients had advanced TNM staging, compared with 27% in the initial stage. There were 39 deaths (30%) documented in the period. The most common tumor site was the sigmoid colon (51%), followed by the ascending colon (16%). The curative intent was performed in most cases, with adjuvant treatment being performed in 40% of the patients. Distant metastases were found in 42% of the patients and 10% had documented disease recurrence. Disease-free survival at two and five years was 69% and 41%, respectively. CONCLUSION: there was a high mortality rate and a low survival rate in colorectal cancer patients operated on urgently.

Periodontite agressiva: conceito e considerações clínicas / Aggressive periodontitis: concept and clinical considerations

A periodontite agressiva (PAg) é uma das formas mais severas da doença periodontal (DP), tendo como característica o início precoce, a rápida instalação, a perda de inserção e a destruição óssea por agentes etiológicos diversificados, como presença de periodontopatógenos altamente virulentos, em contrapartida à quantidade inconsistente de biofilme bacteriano e à susceptibilidade genética do hospedeiro. O sucesso da intervenção terapêutica é dependente de um diagnóstico precoce, seu tratamento não possui protocolos específicos, mas há uma busca por respostas e tratamentos mais eficientes no controle da doença. Diante disso, esse estudo teve por objetivo realizar uma revisão de literatura sobre a PAg, abordando protocolos de tratamento, sua etiologia microbiana, susceptibilidade do indivíduo e envolvimento imunológico e genético associado à doença.

An 81-year-old male with iliopsoas abscess by Streptococcus sanguis.

Iliopsoas muscle abscess is an uncommon condition, which has been growing in incidence. We describe a primary iliopsoas abscess by Streptococcus sanguis affecting an 81-year-old man cured by antibiotic therapy and aspiration procedure. The objective is to enhance the suspicion index about the iliopsoas abscess that may be mistaken for other causes of acute abdomen. The important diagnostic role of abdominal imaging studies is also emphasised.

Anurans from the Middle Jaguaribe River Region, Ceará State, Northeastern Brazil / Anuros da região do Médio Rio Jaguaribe, estado do Ceará, Nordeste do Brasil

The Middle Jaguaribe River region is a poorly sampled area in the Caatingas domain, located in the eastern Ceará State, northeastern Brazil. The Brazilian government agencies considered this region as a priority area for conservation and inventories. In order to fill this biodiversity knowledge gap, we conducted a ten-day rapid inventory of the anuran fauna from April 11 to 20, 2014, surveying different physiognomies of the region. We recorded 19 anuran species belonging to five families: Bufonidae (2), Hylidae (5), Leptodactylidae (9), Microhylidae (2) and Odontophrynidae (1). Most inventories of Caatinga amphibians published to date have been conducted inside protected areas and/or of high altitude (mesic areas known as "brejos de altitude"). The list we present herein contributes to the knowledge of lowland Caatinga sites outside protected areas. We discuss our results in light of taxonomic and geographic features of the anurans sampled.

A Região do Médio Rio Jaguaribe é uma área pobremente amostrada no domínio das Caatingas, localizada no leste do Estado do Ceará, Nordeste do Brasil. O Ministério do Meio Ambiente considera esta região como uma área prioritária para conservação e realização de inventários. Com o objetivo de preencher esta lacuna do conhecimento sobre a biodiversidade, nós conduzimos um inventário rápido da anurofauna de dez dias de 11 a 20 de Abril de 2014, amostrando diferentes fisionomias da região. Nós registramos 19 espécies de anfíbios anuros pertencentes a cinco famílias: Bufonidae (2), Hylidae (5), Leptodactylidae (9), Microhylidae (2) e Odontophrynidae (1). A maioria dos inventários de anfíbios na Caatinga publicados até o presente momento foram conduzidos em áreas de proteção e/ou de áreas de altitude (áreas mésicas conhecidas como “Brejos de Altitude”). A presente lista contribui para o conhecimento de áreas de baixada da Caatinga fora das áreas protegidas. Nós discutimos os resultados è luz de características taxonômicas e biogeográficas dos anuros amostrados.
