ABSTRACT

Abstract Background Chronic low back pain (CLBP) represents a problem in the occupational environment, often associated with disability, sick-leave demands, loss of productivity, anxiety, depression and high socioeconomic cost. The emergence of functional neuroimaging allowed new insights into brain structure and physiology in normality and chronic pain. While occupational related aspects are recognized as important risk factors for chronicity there have not been thus far evaluated by fMRI experiments. The overall objective of this study is to compare the neuronal correlates between groups of individuals CLBP with or without sick-leave demands. Methods A total of 74 individuals were divided into three groups: chronic low back pain with sick-leave demands [CLBP_L]; chronic low back pain without sick-leave demands [CLBP_NL]; individuals without pain or sick-leave demands [Control]. Functional magnetic resonance imaging was used to assess brain function during moderate acute pain stimulation task (thumb controlled pressure). Results After acute painful stimulation, a higher brain response was found in the anterior cingulate and superior and medium frontal gyrus was observed in CLBP_NL vs. CLBP_L ( p < 0,001) and increased brain response in the frontal pole and paracingulate region in control vs. CLBP_L ( p < 0.001) during acute pain stimulation. Conclusion The modulation of acute pain participates in the mechanism propagating chronic pain perception. The lower activation in the superior frontal gyrus observed in the CLBP_L group compared to CLBP_NL, reinforces the idea of an already existing activation in this area.(AU)

ABSTRACT

A camptocormia é uma doença postural caracterizada por flexão anormal da coluna toracolombar que surge na posição ereta, aumenta durante a caminhada e desaparece na posição supina. Na literatura, há descrição de apenas cinco casos de camptocormia secundária a miopatias inflamatórias idiopáticas. No presente relato de caso, descrevemos um paciente do sexo masculino, de 67 anos, com polimiosite há 18 anos, cursando com quadro compatível com camptocormia (estável e sem progressão do quadro clínico). A polimiosite é uma miopatia inflamatória idiopática caracterizada clinicamente por fraqueza muscular simétrica predominantemente proximal dos membros. Entretanto, sendo uma doença autoimune sistêmica, é plausível que ocorra acometimento de musculatura esquelética de forma difusa, incluindo a paravertebral, podendo manifestar-se com camptocormia.


Camptocormia is a postural affliction characterised by abnormal flexion of the thoracolumbar spine, which appears upon standing, increases with walking, and disappears in the supine position. Only five cases of camptocormia secondary to idiopathic infl ammatory myopathies have been described in the literature. In this case report, we describe the case of a male patient 67 years of age who suffered from polymyositis for 18 years, which was associated with manifestations compatible with camptocormia. The clinical manifestations were stable and did not progress. Polymyositis is an idiopathic inflammatory myopathy clinically characterised by symmetric weakness that predominantly affects the proximal muscles. Nevertheless, polymyositis is a systemic autoimmune disease; therefore, the skeletal muscles may be diffusely affected, including the paravertebral muscles, which may manifest as camptocormia.

ABSTRACT

As vasculites antineutrophil cytoplasmic antibody (ANCA, anticorpo anticitoplasma de neutrófilos) associadas (VAAs) são caracterizadas por uma inflamação sistêmica das artérias de pequeno e médio calibre (especialmente no trato respiratório superior e inferior, e nos rins). As VAAs compreendem a granulomatose de Wegener (agora chamada de granulomatose com poliangeíte), poliangeíte microscópica, VAA limitada ao rim e a síndrome de Churg-Strauss. Neste artigo, discutiremos as fases de tratamento dessas vasculites, como fase de indução (com ciclofosfamida ou rituximab) e fase de manutenção (com azatioprina, metotrexato ou rituximab). Além disso, discutiremos como manusear os casos refratários à ciclofosfamida.


In its various forms, antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is characterized by a systemic inflammation of the small and medium-sized arteries (especially in the upper and lower respiratory tracts, as well as in the kidneys). The forms of AAV comprise Wegener's granulomatosis (now called granulomatosis with polyangiitis), microscopic polyangiitis, renal AAV, and Churg-Strauss syndrome. In this paper, we discuss the phases of AAV treatment, including the induction phase (with cyclophosphamide or rituximab) and the maintenance phase (with azathioprine, methotrexate, or rituximab). We also discuss how to handle patients who are refractory to cyclophosphamide.

ABSTRACT

Vasculites de órgão único, ou isoladas, já foram descritas em diversos órgãos e seu achado pode ser acidental. Relatamos um caso de vasculite granulomatosa necrosante isolada de colo uterino em uma paciente de meia-idade, previamente hígida, sexualmente ativa, e cuja pesquisa de DNA de papilomavírus humano (Human Papiloma Virus - HPV) por captura híbrida foi positiva. Não foi identificado comprometimento sistêmico e, como houve excisão completa da lesão, optou-se pelo acompanhamento clínico. Há poucos relatos, na literatura, de acometimento do trato genital feminino de forma isolada, alguns com presença simultânea de lesões que podem ser causadas pelo HPV, postulando-se uma associação patogênica.


Single organ vasculitis (SOV), or isolated vasculitis, has been described in several organs and it can be an accidental finding. We report a case of isolated necrotizing granulomatous vasculitis of the uterine cervix in a middle-aged woman, previously healthy, and sexually active, and whose human papillomavirus (HPV) DNA hybrid capture assay was positive. Systemic involvement was not detected and, since the lesion was completely removed, we opted for a clinical follow-up. The literature has very few reports on the isolated involvement of the female genital tract, and some had concomitant lesions that could be caused by the HPV, indicati.

ABSTRACT

O termo vasculites sistêmicas representa um grupo de doençascaracterizado pela infl amação na parede de vasos sanguíneose conseqüente necrose fi brinóide. Trata-se de uma situaçãoclínica cada vez mais freqüente na população geriátrica, na qual odiagnóstico e tratamento merecem considerações especiais. Asvasculites mimetizam inúmeras condições clínicas freqüentes noidoso, difi cultando seu reconhecimento. São doenças que afetammúltiplos órgãos, muitas vezes com conseqüências devastadoras,necessitando de um diagnóstico preciso e precoce. A forma maiscomum de vasculite, afetando a população geriátrica, é a arteritede células gigantes ou arterite temporal, que ocorre exclusivamenteacima dos 50 anos de idade. Além dessa, a granulomatose de Wegenere a poliangeite microscópica também afetam freqüentementepacientes com mais de 65 anos de idade. Avanços no tratamentodesses pacientes permitiram diminuir a mortalidade e morbidadedas vasculites. No entanto, o próprio tratamento permanece comoum fator importante de morbidade. Os esquemas terapêuticos atuaisvisam induzir rapidamente a remissão da doença, permitindo a trocapor um esquema terapêutico menos agressivo na manutenção daremissão. Nesse sentido, os avanços recentes permitiram alterar aiatrogenia do esquema imunossupressor utilizado no tratamento dasvasculites.
