RESUMO

The objective of this study was to determine in vivo knee kinematics and clinical outcomes of patients who underwent fixed- and mobile-bearing total knee arthroplasty (TKA) at 1- and 2-year follow-up. This prospective double-blinded randomized controlled trial was performed from November 2011 to December 2012. A total of 64 patients were randomized to fixed- and mobile-bearing TKA groups (32 patients in each group). All patients were evaluated with the following: three-dimensional in vivo knee kinematics analysis during gait, stepping up and stepping down stair steps, and getting up from and sitting on a chair; and knee range of motion and patient-reported outcome measures (Knee Outcome Survey Activities of Daily Living Scale [KOS-ADLS] and pain visual analog scale [VAS]) at 1- and 2-year follow-up. Descriptive statistics (means, standard deviations, and percentages) were calculated for all variables. The Kolmogorov-Smirnov test was used to test if variables were normally distributed. A Student's t-test was used to compare continuous variables between patients in the two groups. The chi-square test was used to compare the groups with respect to categorical variables. The α level for statistical significance was set at p < 0.05. The mean axial tibiofemoral rotation in patients who underwent mobile-bearing TKA was significantly higher during gait (13.3 vs. 10.7), stepping up (12.8 vs. 10) stair steps, and getting up (16.1 vs. 12.1) from a chair compared with fixed-bearing TKA patients at 1-year follow-up (p < 0.05). KOS-ADLS function score was significantly higher in the mobile-bearing compared with the fixed-bearing TKA group (32 vs. 27.7) at 1-year follow-up (p < 0.05). No significant difference in kinematics and clinical outcomes between fixed- and mobile-bearing TKA groups was observed at 2-year follow-up (p > 0.05). Based on the results of this study, mobile-bearing TKA allowed a higher degree of rotation when walking, stepping up stair steps, and standing up from a chair, and had higher functional outcomes compared with fixed-bearing TKA at 1-year follow-up. However, no difference in in vivo kinematics or in clinical outcomes was observed between fixed- and mobile-bearing prostheses at 2-year follow-up.

RESUMO

Introdução: A doença de Horton, ou arterite temporal, é a vasculite sistêmica auto-imune mais comum em adultos, especialmente nos idosos. Objetivo: Realizar uma revisão de literatura sobre os diversos aspectos da doença de Horton, evidenciando as manifestações clínicas otorrinolaringológicas. Método: Foram consultadas as bases de dados on-line EMedicine, Encyclopedia of Medicine, FindArticles, LILACS, MEDLINE, Merck Manuals On-Line Medical Library e SciELO, aplicando à pesquisa os termos: Doença de Horton, Arterite Temporal e Arterite de Células Gigantes, para artigos publicados entre 1996 e 2008. Revisão de Literatura: As manifestações clínicas da doença têm início após os 50 anos de idade, sendo mais freqüentes próximo dos 72 anos. A cefaléia intensa, a tumefação temporal, a claudicação mandibular e o déficit visual são os principais sinais e sintomas. Pode haver ainda disacusia, necrose lingual e odinofagia. Considerações Finais: Múltiplos aspectos da Doença de Horton não têm esclarecimentos devidos e, mesmo sendo uma doença que acomete muitos adultos, não possui investigações profundas em grande quantidade. A melhor compreensão desta levará ao incremento das possibilidades de cura dos pacientes e redução da morbidade, especialmente nas áreas oftalmo e otorrinolaringológica.

Introduction: The Horton's disease, or temporal arteritis, is the most common autoimmune systemic vasculitis in adults, especially the old-aged. Objective: To review the literature about the several aspects of the Horton's disease, and confirm the otorhinolaryngologic clinical manifestations. Method: The study searched online databases such as EMedicine, Encyclopedia of Medicine, FindArticles, LILACS, MEDLINE, Merck Manuals On-Line Medical Library and Scielo, and applied to the search the terms: Horton's disease, Temporal Arteritis and Giant Cells Arteritis, for articles published between 1996 and 2008. Literature's Review: The disease's clinical manifestations start after 50 years old, and it's more frequent near 72 years old. The intense headache, temporal tumefaction, mandibular claudication and visual loss are the main signals and symptoms. There may occur dysacusis, necrosis of the tongue and odynophagia. Considerations: Lots of aspects of the Horton's disease do not have their due elucidation and, even being a disease that affects many adults, it doesn't have deep investigations in great quantity. A better understanding of this disease will lead to the increment of cure possibilities and reduction of morbidity in the patients, especially in ophthalmologic and otorhinolaryngologic areas.

RESUMO

Introdução: A Síndrome de Sturge-Weber é uma rara condição de desenvolvimento congênita, sendo caracterizada por uma desordem neurocutânea com angiomas envolvendo as leptomeninges e a pele da face, preferencialmente no trajeto do ramos oftálmico (V1) e maxilar (V2) do nervo trigêmeo. Objetivo: Realizar uma revisão de literatura sobre a Síndrome de Sturge-Weber, enfatizando aspectos atuais. Método: Foram consultadas as bases de dados on-line EMedicine, Encyclopedia of Medicine, Find Articles, LILACS, MEDLINE, Merkmanuals On-Line Medical Library e SciELO, aplicando à pesquisa os termos: Síndrome de Sturge-Weber, síndromes neuro-cutâneas, angiomatose encefalotrigeminal, nevo flamíneo, para artigos publicados entre 1991 e 2007. Revisão de Literatura:O achado clínico mais característico é a presença, já ao nascimento, do nevo flamíneo que atinge, geralmente, uma metade da face podendo estender-se até o pescoço; além disso, outras manifestações clínicas podem estar presentes, como a angiomatose corticocerebral, calcificações cerebrais, epilepsia, afecções oculares, bucais e retardo mental.O diagnóstico é estabelecido por meio da pesquisa de alterações neurológicas e oftálmicas em pacientes com o nevo flamíneo característico, aliando-se aos dados clínicos exames complementares como Tomografia Computadorizada.O tratamento consiste, basicamente, em controlar as manifestações clínicas já evidentes e prevenir o surgimento de outras alterações, principalmente orais e oculares. Conclusão: Esta síndrome, apesar de pouco freqüente, precisa ser precocemente diagnosticada, visto que acarreta uma série de complicações aos seus portadores quando não tratada, principalmente por atingir o Sistema Nervoso Central.Os profissionais da saúde devem, portanto, estar aptos a reconhecer seus sinais e sintomas característicos, e assim melhorar a qualidade de vida desses pacientes.

Introduction: The Syndrome of Sturge-Weber is a rare condition of congenital development, and is characterized by a neurocutaneous disorder with angiomas wrapping the leptomeninges and the face skin, mainly in the course of ophthalmic (V1) and maxillary (V2) branches of the trigeminal nerve. Objective: To review the literature about the Sturge-Weber Syndrome with emphasis on the current aspects. Method: The following databases were searched: EMedicine, Encyclopedia of Medicine, FindArticles, LILACS, MEDLINE, Merck Manuals On-Line Medical Library and Scielo, and the searches applied the terms: Sturge-Weber Syndrome, neurocutaneous syndromes, encephalo-trigeminal angiomatosis, nevus flammeus, in articles published between 1991 and 2007. Literature's Review: The most characteristic clinical statement is the presence, since the birth, of nevus flammeus, that generally reaches one half of the face and may stretch out up to the neck; in addition, other clinical manifestations may be present, like the corticocerebral angiomatosis, cerebral calcifications, epilepsy, ocular and buccal affections and mental retardation. The diagnosis is established by means of the inquiry of neurological and ophthalmic alterations in patients with a characteristic nevus flammeus, allied to the clinical data of complementary exams such as Computerized Tomography. The treatment consists basically of controlling the already confirmed clinical manifestations and preventing from the appearing of other alterations, mainly buccal and ocular. Conclusion: This syndrome is not much frequent, but it needs to be early diagnosed, since it brings a series of complications to its carriers when not treated, specially because of reaching the Nervous Central System. The health professionals have to be suitably able to recognize its characteristic signs and symptoms, and so improve the quality of life of these patients.
