Problemas rotacionales de las extremidades inferiores en niños y adolescentes / Rotational problems of lower limbs in children and adolescents

Las deformidades torsionales de las extremidades inferiores corresponden a una de las causas de visita más frecuente al ortopedista infantil. En la mayoría de los casos, estas consultas son innecesarias, pues se trata de condiciones normales del esqueleto en desarrollo, que suelen corregir espontáneamente. El médico no especialista debe estar familiarizado con los cambios fisiológicos que ocurren en las extremidades inferiores del niño, de manera de identificar aquellos casos severos o aquellos que producen alteraciones funcionales.Estas deformidades, pueden ocurrir en cualquier nivel, desde la pelvis a los pies, por lo que un examen físico sistemático permitirá identificar la causa y proponer un tratamiento de acuerdo a los hallazgos. El único tratamiento eficaz, cuando la situación lo requiere, es la cirugía ortopédica. El uso de plantillas, calzado ortopédico y órtesis no cumplen ninguna función en el manejo de estas alteraciones

Torsional deformities of lower limbs are one of the most frequent causes to visit a pediatric orthopedic surgeon. In most cases, these are unnecessary, as they represent a normal stage of the developing skeleton, which usually correct spontaneously. The nonspecialist physician must be familiar with the physiological changes that occur in children's lower limb, in order to identify those cases that are severe, or cause functional disabilities.These deformities can occur at any level, from the pelvis to the feet, so a systematic physical examination will allow the cause to be identified and treated to be proposed according on to the findings. The only effective treatment, when the situation requires it, is orthopedic surgery. The use of insoles, orthopedic footwear, and orthoses have no role in the management of these alterations

En este trabajo se presentó a un paciente de 32 años que ingresó por pérdida de peso, decaimiento, orinas turbias y dolor en región inguinal derecha. Se describió la evolución clínica, los estudios imagenológicos y de laboratorio que permitieron diagnosticar la presencia del Síndrome de Behçet. Los principales signos presentados por el paciente fueron: ulceraciones bucales recurrentes, la presencia de uveítis anterior y trombosis venosas profundas en miembros inferiores. El cuadro clínico del paciente y la valoración conjunta de varias especialidades médicas constituyeron los factores claves para establecer el diagnóstico definitivo. La evolución del paciente fue satisfactoria con el tratamiento de prednisona y anticoagulantes(AU)

This paper reports a 32-year-old male patient who was hospitalized for weight loss, decay, cloudy urine and pain in the right inguinal region. The clinical evolution, imaging and laboratory studies allowed diagnosing Behçet Syndrome. The patient showed main signs as recurrent mouth ulcerations, anterior uveitis and deep vein thrombosis in the lower limbs. The clinical condition of this patient and the joint assessment of various medical specialties were the key factors in establishing the definitive diagnosis. The patient´s evolution was satisfactory treated with prednisone and anticoagulants(AU)

Fisioterapia intra-hospitalar para pacientes com isquemia crítica de membro inferior: consenso de especialistas / Fisioterapia intrahospitalaria para pacientes con isquemia crítica de miembro inferior: consenso de especialistas / Intra-hospital physical therapy for patients with critical lower limb ischaemia: an expert consensus

RESUMO A isquemia crítica de membro inferior (ICMI) gera impacto nos sistemas de saúde, na qualidade de vida e funcionalidade dos indivíduos diagnosticados. Entretanto, há pouca evidência científica que permita fundamentar a intervenção fisioterapêutica para pacientes internados por ICMI. O objetivo desse estudo foi elaborar um consenso de especialistas sobre a fisioterapia intra-hospitalar para pacientes com ICMI. Para tal, foi utilizado o método Delphi. Um painel de especialistas foi formado por 18 fisioterapeutas que representavam 85,7% da equipe de um hospital de referência em cirurgia vascular. Foram consideradas, para o consenso, as respostas com valor mínimo de concordância de 70% e média ou mediana ≥3,1 na escala Likert. Os questionários abordaram itens da avaliação, objetivos e condutas fisioterapêuticas nas fases pré e pós-cirurgia de revascularização. Definiram-se como itens essenciais a avaliação de sintomas, função cognitiva, musculoesquelética e cardiorrespiratória. Controle da dor, redução de edemas, ganho de amplitude de movimento, deambulação e educação em saúde são objetivos no pré-operatório e o ganho de força muscular na fase pós-operatória. Exercícios passivo, assistido, ativo livre e circulatório, incluindo os membros superiores, estão indicados antes e após as cirurgias. Educação em saúde e deambulação com redução de peso em área de lesão plantar são essenciais em todo o período de internação. A eletroanalgesia foi preconizada no pré-operatório e a elevação do membro inferior e exercícios resistidos no pós-operatório.

RESUMEN La isquemia crítica de miembro inferior (ICMI) afecta a los sistemas de salud y la calidad de vida y funcionalidad de los individuos diagnosticados. Sin embargo, hay poca evidencia científica que fundamente la intervención fisioterapéutica para pacientes internados por ICMI. El objetivo de este estudio fue elaborar un consenso de especialistas sobre la fisioterapia intrahospitalaria para pacientes con ICMI. Para ello, se utilizó el método Delphi. Se formó un panel de expertos con 18 fisioterapeutas que representaban el 85,7% del equipo de un hospital de referencia en cirugía vascular. Se consideraron, para el consenso, las respuestas con un valor mínimo de concordancia del 70% y media o mediana ≥3,1 en la escala Likert. Los cuestionarios abordaron ítems de evaluación, objetivos y conductas fisioterapéuticas en las fases pre y poscirugía de revascularización. Se definieron como elementos esenciales la evaluación de síntomas y las funciones cognitiva, musculoesquelética y cardiorrespiratoria. En el preoperatorio, control del dolor, reducción de edemas, ganancia de amplitud de movimiento, deambulación y educación en salud son los objetivos; en la fase posoperatoria, la ganancia de fuerza muscular. Los ejercicios pasivos, asistidos, activos libres y circulatorios, incluidos los miembros superiores, se indican antes y después de las cirugías. La educación en salud y la deambulación con reducción de peso en el área de lesión plantar son esenciales en todo el período de internación. La electroanalgesia fue preconizada en el preoperatorio; y, en el postoperatorio, elevación del miembro inferior y ejercicios resistidos.

ABSTRACT Critical limb ischemia (CLI) is a disease with a great burden for the healthcare system, patient's functionality and quality of life. However, there is little evidence to guide intrahospital physical therapy programs for patients with CLI. Thus, this study aimed to provide an expert consensus on intrahospital physiotherapeutic care for CLI patients. An expert panel was made up with 18 experienced physical therapists, which represented 85.7% of physical therapists from a reference vascular surgery team in a university hospital. The Delphi method was used to produce a consensus, considering a minimum agreement of 70% and a mean or median score in the Likert scale ≥3.1. The questionnaires included items related to assessment, goals and physiotherapeutic interventions prior and after revascularization. A consensus was reached on assessing symptoms, cognitive, articular, musculoskeletal and cardiorespiratory functions. Pain control, edema drainage, range of motion gain, walking incentive and health education are goals in the pre-operatory and the muscular strengthening in postoperatory phase. In both phases there was a consensus on the use of passive, active-assisted and active exercises, including upper limb exercises. Walking and therapeutic education are essential during the hospitalization period with offloading practices in area of plantar ulcer. Electroanalgesia should be used in preoperative phase and resisted exercises and lower limb elevation at postoperatory.

Força muscular e habilidade de locomoção em indivíduos pós-acidente vascular encefálico crônico / Fuerza muscular y habilidad de locomoción en individuos post-accidente cerebrovascular crónico / Muscle strength and locomotion ability in individuals with chronic stroke

RESUMO O objetivo do estudo foi verificar se existem diferenças na força muscular dos membros inferiores (MMII) e na habilidade de locomoção de indivíduos pós-acidente vascular encefálico (AVE) crônico, classificados como deambuladores comunitários ou não comunitários. Foi realizado um estudo transversal em 60 indivíduos pós-AVE crônico, divididos em deambuladores comunitários (n=33) e não comunitários (n=27) pela velocidade de marcha. A força muscular de sete grupos musculares bilaterais de MMII foi avaliada por meio do teste do esfigmomanômetro modificado e habilidade de locomoção pelo ABILOCO. Estatísticas descritivas foram utilizadas para caracterizar a amostra, e o teste t de Student para amostras independentes, a fim de comparar os dois grupos de indivíduos pós-AVE. Observou-se que os deambuladores comunitários apresentaram maiores valores de força muscular para a maioria dos grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), e na habilidade de locomoção (t=−2,841; p=0,006). Os indivíduos pós-AVE crônico deambuladores comunitários possuem maior força muscular de MMII e mais habilidade de locomoção em comparação aos deambuladores não comunitários. Sugere-se que a avaliação fisioterapêutica de indivíduos pós-AVE inclua, além da mensuração da força muscular de MMII e seu tratamento, a mensuração da percepção da habilidade de locomoção, para análises da evolução do paciente e da eficácia da conduta terapêutica.

RESUMEN El objetivo del estudio fue verificar si existen diferencias en la fuerza muscular de los miembros inferiores (MMII) y en la habilidad de locomoción de individuos post-accidente cerebrovascular encefálico (ACV) crónico, clasificados como deambuladores comunitarios o no comunitarios. Se realizó un estudio transversal en 60 individuos post-ACV crónico, divididos en deambuladores comunitarios (n = 33) y no comunitarios (n = 27) por la velocidad de marcha. La fuerza muscular de siete grupos musculares bilaterales de MMII fue evaluada por medio de la prueba del esfigmomanómetro modificado, y la habilidad de locomoción por el ABILOCO. Las estadísticas descriptivas se utilizaron para caracterizar la muestra, y la prueba t de Student para muestras independientes con el fin de comparar los dos grupos de sujetos post-ACV. Se observó que los deambuladores comunitarios presentaron mayores valores de fuerza muscular para la mayoría de los grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), y en la habilidad de locomoción (t=−2,841; p=0,006). Los individuos post-ACV crónico deambuladores comunitarios poseen mayor fuerza muscular de MMII y más habilidad de locomoción en comparación a los deambuladores no comunitarios. Se sugiere que la evaluación fisioterapéutica de individuos post-ACV incluya, además de la medición de la fuerza muscular de MMII y su tratamiento, la medición de la percepción de la habilidad de locomoción, para análisis de la evolución del paciente y de la eficacia de la conducta terapéutica.

ABSTRACT The objective of this study was to verify if there are differences in the lower-limb muscle strength (LL) and in the locomotion ability among post-stroke patients classified as community or non-community ambulators. A cross-sectional study was conducted in 60 post-chronic stroke subjects, divided into community (n=33) and non-community (n=27) ambulators by gait speed. The muscle strength of seven bilateral muscle groups of LL was evaluated through the modified sphygmomanometer test and locomotion ability through ABILOCO. Descriptive statistics were used to characterize the sample, and Student's t-test was used for independent samples to compare the two groups of post-stroke individuals. We observed that community ambulators had higher values of muscle strength for most muscle groups of LL (−0.973≥t≥3.189; p≤0.04), and in the locomotion ability (t=−2.841; p=0.006). Community ambulators showed higher LL muscle strength and better locomotion ability compared with non-community ambulators. Physiotherapeutic evaluation of post-stroke individuals should include, besides the measurement of LL muscle strength and its treatment, the measurement of the perception of locomotion ability to analyze the evolution of the patient and the efficacy of the therapeutic behavior.

Cicloergômetro na melhora da função motora grossa de crianças com paralisia cerebral: uma revisão sistemática com meta-anális / Cicloergómetro en la mejora de la función motora gruesa de niños con parálisis cerebral: una revisión sistemática con metaanálisis / Cycle ergometer in the improvement of gross motor function of children with cerebral palsy: a systematic review with meta-analysis

RESUMO A paralisia cerebral é um grupo de desordens neurológicas causadora de inúmeros déficits, principalmente relacionados à função motora, comprometendo os movimentos e o seu controle seletivo. Dentre as diversas terapias disponíveis para tentar amenizar esse processo, o cicloergômetro aparece como um aparato estacionário que tem por finalidade facilitar a movimentação dos membros inferiores. Portanto, o objetivo deste estudo foi analisar os efeitos do cicloergômetro na função motora grossa de crianças com paralisia cerebral através da escala Gross Motor Function Measure (GMFM-66). Trata-se de uma revisão sistemática, com inclusão de ensaios clínicos randomizados publicados até julho de 2017. A busca foi realizada nas bases de dados: MEDLINE (PubMed), Physiotherapy Evidence Database (PEDro), SciELO e Embase. Para a avaliação da qualidade metodológica das investigações foi utilizada a escala da Cochrane Handbook. Foram selecionados artigos que aplicaram o cicloergômetro em crianças com paralisia cerebral, comparadas a crianças com paralisia cerebral no grupo-controle ou em outra intervenção, e que avaliaram a função motora grossa com a GMFM. A revisão incluiu três artigos e um total de 127 pacientes. Os resultados mostraram um aumento nos valores da GMFM-66, porém não significativo estatisticamente nem relevantes para uma melhora clínica. Por meio desta revisão sistemática, verificou-se uma grande heterogeneidade nos estudos que abordam esta área e que, apesar do incremento de valores no grupo que realizou o cicloergômetro, não houve diferença estatística quando comparado ao grupo-controle, demonstrando não beneficiar a função motora grossa dessa população quando avaliada pela GMFM66.

ABSTRACT Cerebral palsy is a group of neurological disorders that causes innumerable deficits, mainly related to motor function, compromising movements and their selective control. Among the various therapies available to try to soften this process, the cycle ergometer appears as a stationary apparatus that aims to facilitate the movement of the lower limbs. Therefore, this study aimed to analyze the effects of the cycle ergometer on the gross motor function of children with cerebral palsy by the Gross Motor Function Measure (GMFM-66) scale. This was a systematic review, with inclusion of randomized clinical trials published until July 2017. The search was performed in MEDLINE (PubMed), Physiotherapy Evidence Database (PEDro), SciELO, and Embase. The Cochrane Handbook Scale was used to evaluate the methodological quality of the investigations. We selected articles that applied the cycle ergometer in children with cerebral palsy, compared to children with cerebral palsy in the control group or other intervention, and that assessed gross motor function with GMFM. The review included three articles and a total of 127 patients. The results have shown a not statistically significant increase in GMFM-66 values, not relevant for clinical improvement. This systematic review has found great heterogeneity in the studies addressing this area and, despite the increase in values in the group that used the cycle ergometer, there was no statistical difference compared to the control group, showing that it does not benefit the gross motor function of this population, when evaluated by GMFM-66.

Area Triangulation Method for Automatic Detection of Venous Emptying Maneuvers

Abstract Venous refilling time (VRT) can diagnose the presence of venous diseases in lower limbs. In order to calculate VRT it is necessary to determine the End of the Emptying Maneuvers (EEM). First Derivative Method (FDM) can be employed for automatic detection of the EEM, but its sensitivity to artifacts and noise can degrade its performance. In contrast, studies report that Area Triangulation Method (ATM) evinces effectiveness in biosignals point finding. This work compares the exactness of ATM and FDM for recognition of the EEM. The annotations made by 3 trained human observers on 37 photoplethysmography records were used as a reference. Bland-Altman graphics supported the analysis of agreement among human observers and methods, which was complemented with Analysis of variance and Multiple Comparisons statistical tests. Results showed that ATM is more accurate than FDM for automatic detection of the EEM, with statistically significant differences (p-value < 0.01).

Tai Chi exercise and functional electrical stimulation of lower limb muscles for rehabilitation in older adults with chronic systolic heart failure: a non-randomized clinical trial

Exercise-based training decreases hospitalizations in heart failure patients but such patients have exercise intolerance. The objectives of the study were to evaluate the effect of 12 weeks of Tai Chi exercise and lower limb muscles' functional electrical stimulation in older chronic heart failure adults. A total of 1,084 older adults with chronic systolic heart failure were included in a non-randomized clinical trial (n=271 per group). The control group did not receive any kind of intervention, one group received functional electrical stimulation of lower limb muscles (FES group), another group practiced Tai Chi exercise (TCE group), and another received functional electrical stimulation of lower limb muscles and practiced Tai Chi exercise (FES & TCE group). Quality of life and cardiorespiratory functions of all patients were evaluated. Compared to the control group, only FES group had increased Kansas City Cardiomyopathy Questionnaire (KCCQ) score (P<0.0001, q=9.06), only the TCE group had decreased heart rate (P<0.0001, q=5.72), and decreased peak oxygen consumption was reported in the TCE group (P<0.0001, q=9.15) and FES & TCE group (P<0.0001, q=10.69). FES of lower limb muscles and Tai Chi exercise can recover the quality of life and cardiorespiratory functions of older chronic heart failure adults (trial registration: Research Registry 4474, January 1, 2015).

Experiencia En El Manejo De Los Pacientes Con Melanoma En El Instituto Oncológico Nacional De Panamá En Los Años 2012 Al 2017 / Ex perienc e In The Management Of Patients With Melanoma In The National Oncology Ins titute Of Panama In The Years 2012 To 2017

Introducción: A nivel mundial hay un incremento de la incidencia de melanoma, Panamá no escapa a esta realidad. Para todas las etapas hay riesgo de recurrencia inclusive luego de una cirugía adecuada y elevadas probabilidades de fallecer a causa de metástasis. Este trabajo busca conocer la experiencia del ION en el tratamiento de estos pacientes, la cual no ha sido publicada a la fecha. Objetivos: Descri­ bir las características de los pacientes con melanoma y determinar la Supervivencia Global (OS) y la Su­ pervivencia Libre de Recurrencia (RFS). Metodología: Estudio retrospectivo de los pacientes con melanoma referidos al ION en los años 2012 a 2017 y el análisis de OS y RFS por el método de Kaplan­ Meier. Resultados: Un total de 247 pacientes de melanoma fueron atendidos en el ION en el periodo del estudio; 51.8% eran masculinos con mediana de edad de 65 años. El sitio más común fue acral (31%). En total 46% de nuestros pacientes están en etapas III­IV. Un 65% del total fueron operados, de éstos 80% con resección amplia, 27% con evaluaciones de ganglio centinela y 25% linfadenectomías. Encon­tramos 39% ulcerados y la histología más frecuente fue nodular con 31.6%. Hubo 31.4% de recurren­cias, de los cuales 63.8% era a distancia. La mOS: 55.8 meses en no metastásicos vs 13.1 meses en metastásicos (p<0.0001). La mRFS para los operados fue 53.6 meses y los factores pronósticos fueron ulceración (p=0.007) y realización de linfadenectomía (p=0.000). Conclusión: El diagnóstico de melano­ ma en la población panameña se hace en etapas avanzadas, lo que influye en su pronóstico. Su tasa de supervivencia está muy por debajo de otros países tanto desarrollados como en vías de desarrollo. Estos resultados deben tomarse con cuidado, ya que los factores clásicos descritos en múltiples estu­ dios, no parecen influenciar a nuestra población (edad, sexo, sitio anatómico, subtipo, mitosis). Siendo una enfermedad tan letal hace falta realizar estudios prospectivos a nivel nacional, así como fortalecer la red de prevención y atención primaria.

Introduction: Worldwide there is an increase in the incidence of melanoma, Panama does not escape this reality. For all stages there is a risk of recurrence even after adequate surgery and high chances of death due to metastasis. This work seeks to know the experience of ION in the treatment of these pa­ tients, which has not been published to date. Objectives: To describe the characteristics of patients with melanoma and determine the Global Survival (OS) and the Free Survival of Recurrence (RFS). Metho­ dology: Retrospective study of patients with melanoma referred to the ION in the years 2012 to 2017 and the analysis of OS and RFS by the Kaplan­Meier method. Results: A total of 247 melanoma patients we­ re treated at the ION during the study period; 51.8% were male with a median age of 65 years. The most common site was acral (31%). In total 46% of our patients are in stages III­IV. 65% of the total were ope­ rated, of these 80% with wide resection, 27% with sentinel lymph node evaluations and 25% lymphade­ nectomy. We found 39% ulcerated and the most frequent histology was nodular with 31.6%. There were 31.4% of recurrences, of which 63.8% were distant. The mOS: 55.8 months in non­metastatic vs 13.1 months in metastatic (p <0.0001). The mRFS for the operated patients was 53.6 months and the prog­ nostic factors were ulceration (p = 0.007) and lymphadenectomy (p = 0.000). Conclusion: The diagnosis of melanoma in the Panamanian population is made in advanced stages, which influences its prognosis. Its survival rate is well below other developed and developing countries. These results should be taken with care, since the classical factors described in multiple studies do not seem to influence our population (age, sex, anatomical site, subtype, mitosis). Being such a lethal disease, it is necessary to carry out prospective studies at the national level, as well as to strengthen the prevention and primary care network

Síndrome do aprisionamento da artéria tibial anterior: relato de caso / Anterior tibial artery entrapment syndrome: case report

A claudicação intermitente é uma queixa geralmente relacionada com oclusão arterial secundária a doença aterosclerótica. Entretanto, em pacientes jovens com queixa de claudicação, outras causas devem ser pesquisadas, como a síndrome do aprisionamento da artéria poplítea, síndrome compartimental crônica, compressões ósseas e arterites. Os autores relatam o caso de um paciente com claudicação intermitente devido à compressão extrínseca da artéria tibial anterior pela membrana interóssea, diagnosticada através de angiorressonância durante manobras de dorsiflexão do pé. A paciente foi tratada com sucesso através da liberação do fator compressivo, evoluindo com melhora dos sintomas.

Lower extremity intermittent claudication is usually related to atherosclerotic disease. The most common non-atherosclerotic causes are arterites, chronic compartmental syndrome, bone compression, and popliteal entrapment syndrome. The authors report a case of a patient with intermittent claudication related to anterior tibial artery entrapment caused by the interosseous membrane. Magnetic resonance angiography showed compression of the anterior tibial artery during dynamic maneuvers and the patient was managed by releasing the cause of compression, resulting in relief from claudication.

Changes in lower extremity blood flow during advancing phases of pregnancy and the effects of special footwear / Mudanças no fluxo sanguíneo das extremidades inferiores nas fases avançadas da gravidez e os efeitos de calçado especial

Background: During pregnancy, a number of changes affecting venous blood flow occur in the circulatory system, such as reduced vein wall tension or increased exposure to collagen fibers. These factors may cause blood stagnation, swelling of the legs, or endothelial damage and consequently lead to development of venous disease. Objectives: The aim of this study is to evaluate the effect of special footwear designed to improve blood circulation in the feet on venous blood flow changes observed during advancing phases of pregnancy. Methods: Thirty healthy pregnant women participated in this study at 25, 30, and 35 weeks of gestation. Participants were allocated at random to an experimental group (n = 15) which was provided with the special footwear, or a control group (n = 15). At each data collection session, Doppler measurements of peak systolic blood flow velocity and cross-sectional area of the right popliteal vein were performed using a MySonoU6 ultrasound machine with a linear transducer (Samsung Medison). The differences were compared using Cohen's d test to calculate effect size. Results: With advancing phases of pregnancy, peak systolic velocity in the popliteal vein decreased significantly in the control group, whereas it increased significantly in the experimental group. No significant change in cross-sectional area was observed in any of the groups. Conclusions: Findings in the experimental group demonstrated that wearing the footwear tested may prevent venous blood velocity from reducing during advanced phases of pregnancy. Nevertheless, there is a need for further investigation of the beneficial effect on venous flow of the footwear tested and its application

Contexto: Durante a gravidez, uma série de mudanças que afetam o fluxo venoso ocorrem no sistema circulatório, tais como menor tensão da parede venosa ou aumento da exposição a fibras de colágeno. Esses fatores podem causar estagnação sanguínea, inchaço das pernas ou dano endotelial e, consequentemente, levar ao desenvolvimento de doença venosa. Objetivos: O objetivo deste estudo foi avaliar o efeito do uso de calçados especiais projetados para melhorar a circulação sanguínea dos pés sobre as mudanças no fluxo venoso observadas nas fases avançadas da gravidez. Métodos: Trinta gestantes saudáveis participaram deste estudo às 25, 30 e 35 semanas de gestação. As participantes foram aleatoriamente designadas a um grupo experimental (n = 15) que recebeu calçados especiais, ou um grupo controle (n = 15). A cada sessão de coleta de dados, foram obtidas medidas Doppler do pico de velocidade do fluxo sanguíneo sistólico e da área transversal da veia poplítea direita, utilizando-se um aparelho de ultrassom MySonoU6 com transdutor linear (Samsung Medison). As diferenças foram comparadas utilizando-se o teste d de Cohen para calcular o tamanho do efeito. Resultados: Nas fases avançadas da gravidez, o pico da velocidade sistólica na veia poplítea diminuiu significativamente no grupo controle, porém aumentou significativamente no grupo experimental. Não houve mudanças significativas na área transversal da veia poplítea em nenhum dos grupos. Conclusões: Os achados do grupo experimental demonstraram que o uso dos calçados especiais testados pode evitar que a velocidade do fluxo venoso diminua nas fases avançadas da gravidez. No entanto, mais estudos são necessários para investigar os efeitos benéficos sobre o fluxo venoso do uso dos calçados testados e suas aplicações

Muscle strength and body composition in severe obesity

OBJECTIVE: The aim of our study was to evaluate associations between maximum voluntary contraction torques of the lower limbs and body composition for subjects with severe obesity. METHODS: Body composition was evaluated by bioelectrical impedance analysis, and maximum voluntary contraction torques of the lower limbs were measured using an isokinetic dynamometer. One hundred thirty-two patients were enrolled (100 females and 32 males). Eighty-seven patients had a body mass index between 40 and 49.9 kg/m2 (the A group), and 45 patients had a body mass index between 50 and 59.9 kg/m2 (the B group). RESULTS: Absolute extension and flexion torques had weak associations with fat-free mass but a moderate association with absolute extension torque and fat-free mass of the lower limbs. There were no significant differences between the A and B groups with respect to absolute extension and flexion torques. For the A group, absolute extension and flexion torques were moderately associated with fat-free mass and with fat-free mass of the lower limbs. For the B group, there were only moderate associations between absolute extension and flexion torques with fat-free mass of the lower limbs. CONCLUSIONS: Our findings demonstrate that both groups exhibited similar absolute torque values. There were weak to moderate associations between absolute extension and flexion torques and fat-free mass but a moderate association with fat-free mass of the lower limbs. Individuals with severe obesity should strive for greater absolute torques, fat-free mass and especially fat-free mass of the lower limbs to prevent functional limitations and physical incapacity.

Perfil das alterações vasculares periféricas em dependentes de crack acompanhados em Centro de Atenção Psicossocial para Álcool e Drogas (CAPS-AD) / Profile of peripheral vascular changes in crack-cocaine addicts receiving treatment at a Psychosocial Care Center for Alcohol and Drugs

CONTEXTO: O consumo de crack é um dos grandes desafios em saúde pública, e o uso dessa droga tem efeitos diretos na saúde de seus usuários. OBJETIVOS: Avaliar o perfil das alterações vasculares em pacientes com dependência de crack em Centro de Atenção Psicossocial para Álcool e Drogas (CAPS-AD) e observar os possíveis efeitos vasculares periféricos. MÉTODOS: Trata-se de um estudo observacional, descritivo, de corte transversal. Os pacientes da amostra foram submetidos a um questionário objetivo para avaliar questões demográficas, padrão de uso da droga, coexistência de diabetes melito, hipertensão arterial ou tabagismo, exame físico e ecográfico. Os dados foram sumarizados e analisados estatisticamente com teste qui-quadrado ou teste exato de Fisher. RESULTADOS: A média de idade da amostra foi de 33,29 (±7,15) anos, e 74% eram do gênero masculino. A média de idade de início de uso da droga foi de 23,4 (±7,78) anos, com tempo médio de uso de 9,58 (±5,64) anos. O consumo médio diário de pedras de crack foi de 21,45 (±8,32) pedras. A alteração de pulsos em membros inferiores foi mais frequente em mulheres. A prevalência do espessamento da parede arterial nos membros inferiores foi de 94,8%. O tempo de uso da droga apresentou associação estatística (p = 0,0096) com alteração do padrão de curva espectral das artérias dos membros inferiores. CONCLUSÕES: Há alterações vasculares periféricas em usuários de crack. O tempo de uso da droga exerceu um maior impacto nesse sistema, o que sugere associação entre o uso do crack e a diminuição de fluxo arterial.

BACKGROUND: Consumption of crack is one of the major challenges in public health and taking this drug has direct effects on the health of those who use it. OBJECTIVES: To evaluate the profile of vascular abnormalities in patients receiving treatment for crack dependency at a Psychosocial Care Center for Alcohol and Drugs and to observe possible peripheral vascular effects. METHODS: The study design is observational, descriptive and cross-sectional. An objective questionnaire was administered to the patients in the sample to collect data on demographic details; drug use profile; and concomitant diabetes mellitus, arterial hypertension and/or smoking; and physical and ultrasound examinations were conducted. Data were summarized and analyzed statistically with the chi-square test or Fisher’s exact test. RESULTS: The mean age of the sample was 33.29 (±7.15) years, and 74% were male. Mean age at onset of drug use was 23.4 (±7.78) years and mean time since onset was 9.58 (±5.64) years. Mean consumption of crack rocks was 21.45 (±8.32) per day. The rate of abnormal lower limb pulses was higher among women. The prevalence of artery wall thickening in lower limbs was 94.8%. Time since starting to use crack exhibited a statistically significant association (p = 0.0096) with abnormalities in the spectral curve profiles of lower limb arteries. CONCLUSIONS: Crack users exhibit peripheral vascular disorders. Length of time since starting to use the drug had the greatest impact on this system, suggesting an association between crack use and reduced arterial flow.

Work and power reduced in L-dopa naïve patients in the early-stages of Parkinson’s disease / Trabalho e potência reduzidos em indivíduos com doença de Parkinson sem L-dopa nos estágios iniciais

ABSTRACT Studies which have investigated muscular performance during the initial stages of Parkinson´s disease (PD) without L-dopa treatments were not found. Objective to assess whether muscular performance, work and power, of the trunk and lower limbs in L-dopa naïve patients in the early stages of PD was lower than those of healthy subjects and to compare muscular performance between the lower limbs. Method Ten subjects with PD, Hoehn and Yahr (HY) I-II, L-dopa naïve and 10 subjects in the control group were assessed with the isokinetic dynamometer. Results ANOVAs revealed that work and power measures of the trunk, hip, knee, and ankle muscular groups were lower in PD compared with the control group (p < 0.05). There were no significant differences in muscular performance between the lower limbs. Conclusion The results suggested the use of specific exercises, as rehabilitation strategies, to improve the ability to produce work and power with this population.

A fisioterapia tem papel importante no processo de prevenção e recuperação de danos causados pela doença venosa crônica (DVC), com técnicas adequadas e focadas no quadro clínico da doença, sendo então denominada de fisioterapia vascular. O tratamento fisioterapêutico vascular precoce pode aliviar os sintomas da doença, reduzir o risco de úlceras venosas e melhorar a qualidade de vida do portador de DVC. O objetivo desta revisão de literatura foi elaborar um protocolo de tratamento fisioterapêutico vascular, mostrando evidências e benefícios das técnicas da fisioterapia vascular e sugerindo como podem ser utilizadas no tratamento da DVC. Trata-se de um estudo de revisão de literatura através de referências sobre o tema, considerando os materiais disponíveis nas bases de dados bibliográficos LILACS e SciELO, publicados no período de 1990 a 2014. Esse protocolo constitui uma proposta de tratamento direcionada às necessidades dos indivíduos com DVC, a fim de proporcionar uma melhor qualidade de vida.

Physiotherapy has an important role to play in prevention of and recovery from the damage cause by chronic venous disease (CVD), employing techniques that are adapted to and focused on clinical disease status, in which form it is known as vascular physiotherapy. Early initiation of treatment with vascular physiotherapy can relieve symptoms of the disease, reduce the risk of venous ulcers and improve the quality of life of CVD patients. The objective of this literature review was to develop a protocol for treatment with vascular physiotherapy, compiling evidence of the benefits of each vascular physiotherapy technique and suggesting how they can be used for treatment of CVD. This is a review of literature investigating the subject that is listed on the LILACS and SciELO bibliographic databases and was published from 1990 to 2014.

Sports injuries profile of a first division Brazilian soccer team: a descriptive cohort study

ABSTRACTObjective:To establish the injury profile of soccer players from a first division Brazilian soccer team. In addition, we investigated the association between the characteristics of the injuries and the player's age and position.Method: Forty-eight players from a Brazilian first division soccer team were followed during one season. Descriptive statistics were used to characterize the injury profile. Spearman's tests were used to verify the association between the number and severity of injuries and the player's age. Chi-square test was used to verify the association between type of injury and player's position. Fisher's exact test was used to verify the association between the severity of injuries and player's position.Results: The incidence of injuries was 42.84/1000 hours in matches and 2.40/1000 hours in training. The injury severity was 19.5±34.4 days off competition or training. Lower limb was the most common location of injury and most injuries were muscular/tendinous, overuse, non-recurrent, and non-contact injuries. Player's age correlated with the amount and severity of muscle and tendon injuries. Defenders had more minimal injuries (1-3 days lost), while forwards had more moderate (8-28 days lost) and severe injuries (>28 days lost). Furthermore, wingbacks had more muscle and tendon injuries, while midfielders had more joint and ligament injuries.Conclusion: The injury profile of the Brazilian players investigated in this study reflected regional differences in soccer practices. Results confirm the influence of the player's age and position on the soccer injuries profile.

Lower limb muscle strength is associated with functional performance and quality of life in patients with systemic sclerosis

Background: Complaints of peripheral muscle weakness are quite common in patients with systemic sclerosis (SSc). It is likely that the muscle impairments may reduce the patients' exercise performance, which in turn may decrease their functional capacity and exert a direct impact on their quality of life. Objectives: To assess the peripheral and respiratory muscle strength in individuals with SSc and to investigate their correlation with the 6-min walk distance (6MWD) and quality of life measurements. Moreover, we aimed to characterize their nutritional status, pulmonary function, functional capacity, and quality of life compared to the controls. Method: The present cross-sectional study included 20 patients with SSc and 20 control subjects. All of the participants were subjected to isometric dynamometry, surface electromyography, bioelectrical impedance analysis, pulmonary function testing, and the 6-min walk test. Patients with SSc also responded to the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the Health Assessment Questionnaire Disability Index (HAQ-DI). Results: The individuals with SSc exhibited a reduction in quadriceps strength (p=0.0001), increased quadriceps fatigability (p=0.034), impaired pulmonary function, and a reduced 6MWD (p=0.0001) compared to the controls. Quadriceps strength was significantly correlated with the 6MWD (Rho=0.719; p=0.0004) and the HAQ-DI (Rho=-0.622; p=0.003). We also found significant correlations between quadriceps fatigability and maximal inspiratory (Rho=0.684; p=0.0009) and maximal expiratory (Rho=0.472; p=0.035) pressure. Conclusions: Patients with SSc exhibited reduced respiratory muscle and quadriceps strength and an increase in its fatigability. In these individuals, there was a relationship between quadriceps strength, functional capacity, and quality of life. .

Factors that influence in the turnout in ballet dancers with knee pain / Factores que influyen en el turnout em bailarinas com dolor em lãs rodillas / Fatores que influenciam no turnout em bailarinas clássicas com dor nos joelhos

The turnout, primary gesture in classical ballet, refers the 180º of the feet. The lateral rotation provides the greatest amount of degrees necessary to perform the position perfectly. If performed improperly, it can generate problems, specialy in the knees, causing pain. The aim of this study was to evaluate the factors that influence the implementation of turnout in adolescents ballet dancers with knee pain and to compare them to the dancers without pain. Twenty three (23) ballet dancers with knee pain and 26 ballet dancers without pain were evaluated for range of motion of external rotation of the hip, muscle strength, femoral neck anteversion and static and dynamic turnout. The angles were measured with a manual goniometer, and the strength of the abductor muscle groups, external rotators and hip extensors with isometric dynamometer. The analysis was performed using ANOVA and Mann-Whitney. Range of motion of external rotation of the hip, femoral neck anteversion and muscle strength were similar between groups. The dynamic turnout was lower in ballet dancers with knee pain (p=0.02) and ballerinas with angular deficits above 10% over the static group had lower turnout under the bilateral extensor muscle group (p=0.04 and 0.03, right left) and right abductor (p=0.03). Although anatomical factors can influence the lateral rotation of the turnout, the angle decreased dynamic turnout was related to the group of dancers with pain. This suggests that training based on proximal awareness of movement can prevent and minimize burdens on the knees of classical dancers teens.

El turnout, principal gesto del ballet clásico, se refiere a la posición de 180º entre los pies. La rotación lateral de la cadera proporciona una mayor cantidad de grados necesarios para realizar la posición perfectamente. Si se realiza de forma inadecuada, puede generar compensaciones, preferentemente en las rodillas, generando dolor. El objetivo de este estudio fue evaluar los factores que influyen en la ejecución del turnout en bailarinas clásicas adolescentes con dolor en las rodillas y comparar las bailarinas y sin dolor. Se evaluaron a 23 bailarinas con dolor y 26 bailarinas sin dolor en cuanto al rango de movimiento de rotación lateral de la cadera, la fuerza muscular, a la anteversión del cuello femoral y al turnout estático y dinámico. Los ángulos fueron medidos con un goniómetro manual, y la fuerza de los grupos musculares abductores, rotadores externos y extensores de la cadera con dinamómetro isométrico. El análisis se realizó por medio del ANOVA y Mann-Whitney. El rango de movimiento, la anteversión del cuello femoral y la fuerza del músculo fueron similares entre los grupos. El turnout dinámico fue menor en el grupo de bailarinas con dolor (p=0,02), y las bailarinas con déficits angulares superiores a 10% en relación al turnout estático presentaron menor fuerza del grupo muscular de los extensores bilaterales (p=0,04 y 0,03, derecha e izquierda) y abiductores derecho (p=0,03). Aunque los factores anatómicos pueden influir en la rotación lateral del turnout, la disminución del ángulo del turnout dinámico se relacionó con el grupo de bailarinas con dolor. Tal hecho sugiere que el entrenamiento basado en la conciencia proximal del movimiento puede prevenir y minimizar las sobrecargas en las rodillas de bailarinas clásicas adolescentes.

O turnout, gesto principal do balé clássico, refere-se à posição de 180º entre os pés. A rotação lateral do quadril fornece a maior quantidade de graus necessários para realizar a posição com perfeição. Se executada de forma inadequada, pode gerar compensações, preferencialmente nos joelhos, ocasionando dor. O objetivo deste estudo foi avaliar fatores que influenciam na execução do turnout em bailarinas clássicas adolescentes com dor nos joelhos e comparar a bailarinas sem dor. Foram avaliadas 23 bailarinas com dor e 26 bailarinas sem dor quanto à amplitude de movimento de rotação lateral do quadril, força muscular, à anteversão do colo femoral e ao turnout estático e dinâmico. Os ângulos foram mensurados com goniômetro manual, e a força dos grupos musculares abdutores, rotadores laterais e extensores do quadril com dinamômetro isométrico. A análise foi feita por meio do ANOVA e Mann-Whitney. A amplitude de movimento, a anteversão do colo femoral e a força muscular foram semelhantes entre os grupos. O turnout dinâmico foi menor no grupo de bailarinas com dor (p=0,02), e bailarinas com déficits angulares acima 10% em relação ao turnout estático apresentaram menor força do grupo muscular dos extensores bilateral (p=0,04 e 0,03, direita e esquerda) e abdutores direito (p=0,03). Embora fatores anatômicos possam influenciar na rotação lateral do turnout, a diminuição angular do turnout dinâmico esteve mais relacionada ao grupo de bailarinas com dor. Tal fato sugere que o treinamento baseado na conscientização proximal do movimento pode prevenir e minimizar as sobrecargas nos joelhos de bailarinas clássicas adolescentes.

Treatment of critical lower limb ischemia using a hybrid technique / Tratamento de isquemia crítica de membro inferior com técnica híbrida

Critical ischemia of a lower limb is a condition that threatens its viability and must be treated promptly to avoid major amputation. Revascularization is the most effective treatment method and is performed using surgical or endovascular techniques. For patients with thoracoabdominal aortic aneurysms, combining these two approaches into a "hybrid technique" makes it possible to treat patients who could not be adequately treated by either technique in isolation. We report on a case of lower limb critical ischemia treated using a combination of surgery and endovascular techniques, in an application of the hybrid technique in a different arterial bed...

A isquemia crítica de membro inferior é uma condição que constitui uma ameaça à viabilidade do membro e deve ser prontamente tratada para evitar uma amputação maior. A revascularização é o tratamento mais eficaz, podendo ser por técnica cirúrgica ou endovascular. Nos pacientes com aneurisma toracoabdominal da aorta, a combinação das duas técnicas, denominada técnica híbrida, permite ampliar a possibilidade de tratamento de pacientes que não seriam adequadamente tratados por nenhuma das duas técnicas isoladamente. Descrevemos o tratamento de uma isquemia crítica de membro inferior utilizando a combinação de cirurgia convencional e tratamento endovascular, também se constituindo, assim, em uma técnica híbrida, mas em outro território arterial...
