ABSTRACT

Estudo de caracterização da força e da função muscular nas disferlinopatias para estabelecer biomarcadores de habilidades motoras com amostra de 40 pacientes, tendo sido avaliados força muscular (Medical Research Council - MRC), percentual de MRC, tempo de execução para deambular e escores nas Escalas de Vignos, Egen Klassifikation, Avaliação Funcional para Distrofia Muscular de Duchenne (FES-DMD) e North Star Ambulatory Assessment adaptada. Prevalência da disferlinopatia de 25,5% na amostra total de distrofias (1340), idade média de 36,5 anos, 52,5% do sexo masculino e 75% deambuladores. Músculos mais fracos: abdominal, glúteos, íliopsoas, isquiotibial, quadríceps femoral, tibial anterior e deltoide médio. Correlação forte entre MRC e tempo para deambular (r = 0,77) e, muito forte da MRC distal de membros inferiores com aNSAA (r = 0,90). Interação da MRC dos membros superiores e inferiores nos segmentos proximal e distal (p < 0,001), sendo mais evidente em membros superiores que inferiores. Taxa variável de progressão da doença com 60% dos pacientes moderadamente ou gravemente afetados, com mais de 12 anos de doença. Estudo mostra que padrão de fraqueza muscular dos brasileiros com disferlinopatia é proximal e distal dos MMII, com comprometimento associado da região proximal dos MMSS, além de elucidar as habilidades motoras em relação ao processo de locomoção e disfunções cardiorrespiratórias.

ABSTRACT

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease marked by fluctuating course of muscle weakness. OBJECTIVES: The current study was designed to evaluate plasma levels of cytokines (IL-2, IL-4, IL-6, IL-10, TNF, IFN-γ, and IL17A) in patients with MG and controls and to investigate whether cytokines levels are associated with clinical parameters. This study was conducted at the Neuromuscular Diseases Outpatient Clinic, Hospital das Clínicas, Universidade Federal de Minas Gerais (UFMG), Brazil. METHODS: Peripheral blood was drawn, and plasma levels of cytokines were measured by cytometric bead array (CBA) in 80 treated patients with MG and 50 controls. The MG Composite (MGC) was used to evaluate muscle weakness and severity of typical motor symptoms of MG. RESULTS: Patients with MG undergoing treatment exhibit lower levels of all evaluated cytokines compared to controls. There was a negative correlation between IL-6 levels and the MG Composite score, indicating that higher levels of IL-6 were associated with better control of the disease. CONCLUSION: This exploratory study suggests that IL-6 is associated with MG clinical status, as assessed by the MGC.


INTRODUÇÃO: A Miastenia Gravis (MG) é uma doença autoimune caracterizada por fraqueza muscular flutuante. OBJETIVOS: avaliar os níveis plasmáticos de citocinas (IL-2, IL-4, IL-6, IL-10, TNF, IFN-γ, e IL-17A) em pacientes com MG e controles e investigar se essas citocinas estão associadas com parâmetros clínicos. Este estudo foi conduzido no ambulatório de doenças neuromusculares do Hospital das Clínicas, Universidade Federal de Minas Gerais (UFMG), Brasil. MÉTODOS: Foi coletado sangue periféricos e os níveis plasmáticos das citocinas foram medidos por citometria em 80 pacientes com MG tratados e em 50 controles. O MG composite (MGC) foi utilizado para avaliar a fraqueza muscular e a gravidade dos sintomas motores típicos da MG. RESULTADOS: Os pacientes com MG em tratamento apresentaram menores níveis de todas as citocinas avaliadas comparados ao controle. Houve uma correlação negativa entre os níveis de IL-6 e o MGC, indicando que altos níveis de IL-6 estão associados com melhor controle da doença. CONCLUSÃO: este estudo exploratório sugere que a IL-6 está associada com o status clínico da MG, quando avaliado pelo MGC.

ABSTRACT

Introducción: Durante el envejecimiento se observa involución de algunos sistemas corporales. Entre estos cambios, los que afectan al sistema osteomuscular como la sarcopenia y la debilidad muscular, pueden alterar el desarrollo de actividades de la vida diaria, y por lo tanto, afectar la calidad de vida relacionada con la salud. Objetivo: Determinar la relación entre la fuerza de prensión manual y la calidad de vida relacionada con la salud en personas mayores. Métodos: Estudio descriptivo, correlacional. Evaluó 79 personas mayores (63 mujeres y 16 hombres) entre 65 y 78 años, de tres organizaciones sociales de la ciudad de Talca, Chile, seleccionados a través de un muestreo no probabilístico por conveniencia. Para medir la fuerza de prensión manual se utilizó un dinamómetro de mano y el cuestionario SF-36 fue usado para valorar la calidad de vida relacionada con la salud. Resultados: Se observaron relaciones significativas entre la fuerza de prensión manual y las dimensiones de la calidad de vida función física (p = 0,03; r = 0,76), dolor corporal (p = 0,01; r = 0,44) y salud general (p = 0,05; r = 0,48). Conclusiones: Existe relación entre la fuerza de prensión manual y tres dimensiones de la calidad de vida relacionada con la salud de personas mayores. Estos hallazgos corroboran la relevancia de evaluar la fuerza muscular en personas mayores como un marcador de salud y calidad de vida en estas(AU)


Introduction: During aging, involution of some body systems is observed. Among these changes, those that affect the musculoskeletal system such as sarcopenia and muscle weakness can alter the development of activities of daily life, and therefore affect health-related quality of life. Objective: to determine the relationship between hand grip strength and quality of life in elderly. Methods: Cross-sectional study. A total of 79 elderly (63 women and 13 men) between 65 and 78 years of age from three social organizations of Talca, Chile was included. A non-probabilistic convenience sample was used. To measure manual grip strength and the SF-36 questionnaire was used. Results: Significant relationships between hand grip strength and dimensions of quality of life, physical function (p = 0,03; r = 0,76), body pain (p = 0,01; r = 0,44) and general health (p = 0,05; r = 0,48) were observed. Conclusions: There is a relationship between hand grip strength and three measurements of quality of life in elderly. These findings corroborate the relevance of evaluating muscle strength in older people as a marker of health and quality of life in elderly(AU)

ABSTRACT

OBJECTIVE@#To study the clinical features of children with Guillain-Barré syndrome (GBS) and the significance of Brighton criteria in childhood GBS.@*METHODS@#A retrospective analysis was performed on the medical data of 72 children with GBS. Brighton criteria were used for the grading of diagnostic certainty (level 1 as the highest level, and level 4 as the lowest level). A Spearman's rank correlation analysis was used to evaluate the correlation of auxiliary examinations with the level of diagnostic certainty of Brighton criteria.@*RESULTS@#A total of 72 children with GBS were enrolled, with a mean age of onset of (98±32) months. All children (100%, 72/72) had weakness of bilateral limbs and disappearance or reduction of tendon reflex, and limb weakness reached the highest level of severity within 4 weeks. Of all the 72 children, 68 (94%) had positive results of neural electrophysiological examination and 51 (71%) had positive results of cerebrospinal fluid (CSF) examination, and the positive rate of neural electrophysiological examination was significantly higher than that of CSF examination (@*CONCLUSIONS@#Most of the children with GBS meet Brighton criteria level 1, and the positive results of CSF examination and neural electrophysiological examination play an important role in improving the level of diagnostic certainty of Brighton criteria. Neural electrophysiological examination has a higher positive rate than CSF examination in the early stage of the disease.

ABSTRACT

A paralisia periódica hipocalêmica tireotóxica é uma complicação rara do hipertireoidismo. Caracteriza-se por episódios de fraqueza muscular recorrente, associado à tireotoxicose e hipocalemia. Ocorre frequentemente em pacientes do sexo masculino e de origem asiática. Nesse contexto, o objetivo deste estudo é descrever o relato de caso de um paciente acometido por paralisia periódica hipocalêmica tireotóxica com redução acentuada da qualidade de vida e internações recorrentes devido a quadro agudo de tetraparesia flácida ascendente associado a hipocalemia grave por não adesão ao tratamento do hipertireoidismo. A paralisia periódica hipocalêmica tireotóxica apresenta evolução favorável quando reconhecida e tratada com controle inicial dos sintomas para normalização sérica do potássio e posterior resolução do quadro tireotóxico.


Thyrotoxic hypokalemic periodic paralysis is a rare complication of hyperthyroidism. The issue has been characterized by episodes of recurrent muscle weakness associated with thyrotoxicosis and hypokalemia. It occurs most often in male patients of Asian origin. This study aims on describing the case report of a patient affected by thyrotoxic hypokalemic periodic paralysis with intense reduction in life quality and recurrent hospitalizations due to ascending acute flaccid tetraparesis associated with severe hypokalemia due to non-adherence to treatment of hyperthyroidism. Thyrotoxic hypokalemic periodic paralysis presents a favorable evolution when identified and treated with initial symptom control for serum potassium normalization and subsequent resolution of the thyroid toxicity.

ABSTRACT

ABSTRACT Objective To compare body composition of postmenopausal women with and without dynapenia, defined by different cut-off points. Methods Body composition was assessed by electrical bioimpedance and the nutritional status by the body mass index. Dynapenia was diagnosed according to handgrip strength, using the following cut-off points: handgrip strength <16kgf and <20 kgf. Results A total of 171 women (50 to 92 years of age) participated in the investigation. The mean age of non-dynapenic and dynapenic women (handgrip strength <20kgf) was 69.4±8.2 and 74.5±8.2 years, respectively. The mean age of women with dynapenia (handgrip strength <16kgf) was 75.0±10.1 years and non-dynapenic women, 71.1±8.2 years. It was found that dynapenic women, with handgrip strength <20 and <16kgf, had an average of 2.38 and 2.47kg less muscle mass respectively, when compared to non-dynapenic women (p<0.05). However, there was no difference in muscle mass between the different dynapenic groups. Non-dynapenic women (handgrip strength ≥20kgf) had more total (3.55kg) and central fat (1.47kg) (p<0.05). Conclusion Dynapenic women, diagnosed considering both cutoff points, had less total and segmental muscle mass compared to non-dynapenic women. In addition, dynapenic women with handgrip strength <20kgf had lower total and trunk adiposity.


RESUMO Objetivo Comparar a composição corporal de mulheres na pós-menopausa com e sem dinapenia a partir de diferentes pontos de corte. Métodos A composição corporal foi avaliada por bioimpedância elétrica e o estado nutricional pelo índice de massa corporal. A dinapenia foi diagnosticada por meio da força de preensão manual, utilizando-se os seguintes pontos de corte: força de preensão manual <16kgf e <20kgf. Resultados Participaram da pesquisa 171 mulheres (50 a 92 anos). A média de idade das não dinapênicas e das dinapênicas (força de preensão manual <20 kgf) foi 69,4±8,2 e 74,5±8,2 anos, respectivamente. As mulheres com dinapenia pela força de preensão manual <16kgf apresentaram média de idade de 75,0±10,1 anos e as não dinapênicas tinham, em média, 71,1±8,2 anos. Verificou-se que as mulheres dinapênicas, com força de preensão manual <20 e <16kgf, tinham em média 2,38 e 2,47kg a menos de massa muscular quando comparadas às não dinapênicas (p<0,05). Contudo, não foi observada diferença na massa muscular entre os diferentes grupos dinapênicos. As mulheres não dinapênicas (força de preensão manual ≥20kgf) apresentaram maior gordura total (3,55kg) e central (1,47kg) (p<0,05). Conclusão As mulheres dinapênicas, diagnosticadas por ambos os pontos de corte, apresentaram menor massa muscular total e por segmento em relação às não dinapênicas. Ademais, as dinapênicas com força de preensão manual <20kgf possuíam menor adiposidade total e no tronco.

ABSTRACT

INTRODUÇÃO: Após longos períodos de internação, o idoso pode desenvolver fraqueza muscular que pode impactar sua independência funcional pós-hospitalização. OBJETIVO: Avaliar a presença de fraqueza muscular em pacientes idosos internados em uma unidade de terapia intensiva (UTI). METODOLOGIA: Trata-se de um estudo transversal, descritivo, de abordagem quantitativa, que avaliou a funcionalidade por meio do questionário Índice de Katz (IK), a força muscular pós-hospitalização em UTI por meio da força de preensão manual (FPM) e pelo Medical Research Council (MRC). A amostra foi composta de 60 pacientes com idade mediana de 76 (60-99) anos. Destes, 36 (60%) eram do gênero feminino e 24 (40%) do masculino. RESULTADOS: Pós-UTI, 86,7% dos idosos apresentaram dependência funcional. Idosos do gênero feminino apresentaram FPM estatisticamente menores que as do gênero masculino, sete (0-24) vs. 17 (1-37) (p < 0,001). Idosas em uso de ventilação mecânica (VM) e sedação apresentaram FPM e MRC estatisticamente menores quando comparadas às que não fizeram uso desse recurso (p < 0,001): FPM VM 1 (0-13) vs. 11 (0-24) p < 0,001; MRC VM 35 (14-48) vs. 43 (27-57) p < 0,001; FPM sedação 0 (0-12) vs. 9 (0 - 24) p < 0,001; MRC sedação 34 (14-36) vs. 42 (22-57) p < 0,001, respectivamente. Por fim, existe correlação inversamente proporcional e FPM e MRC e tempo de internamento na UTI, rô de Spearman = -0,267 (p = 0,0039) e rô = -0,347 (p = 0,007), respectivamente. CONCLUSÃO: Mulheres apresentaram redução da força muscular quando fizeram uso de VM e sedação, quando comparadas às que não fizeram. À medida que se aumenta o tempo de internação na UTI, mais a força muscular diminui.


INTRODUCTION: After long periods of hospitalization, older adults may develop muscle weakness that can affect their functional independence after discharge. OBJECTIVE: To assess muscle weakness in older patients admitted to an ICU. METHOD: This cross-sectional, descriptive study with a quantitative approach assessed functional independence with the Katz Index and post-ICU muscle strength with a handgrip strength (HS) test and the Medical Research Council (MRC) sum-score. The sample consisted of 60 patients with an average age of 76 (60-99) years, 36 (60%) of whom were female. RESULTS: Post-ICU, 86.7% of the patients were functionally dependent. Female patients had significantly lower HS than males: 7 (0-24) vs. 17 (1-37) (p < 0.001). Female patients who received mechanical ventilation (MV) or sedation had significantly lower HS and MRC scores than those who did not (p < 0.001): HS MV 1 (0-13) vs. 11 (0-24) p < 0.001; MRC MV 35 (14-48) vs. 43 (27-57) p < 0.001; HS sedation 0 (0-12) vs. 9 (0-24) p < 0.001; MRC sedation 34 (14-36) vs. 42 (22-57) p < 0.001, respectively. Finally, there was an inversely proportional correlation between HS, MRC scores, and ICU length of stay, Spearman's rho = -0.267 (p = 0.0039) and Spearman's rho = -0.347 (p = 0.007), respectively. CONCLUSION: Older women who received mechanical ventilation and sedation have lower muscle strength than those who did not. As the ICU length of stay increases, muscle strength decreases.

ABSTRACT

Abstract Objective: Duchenne muscular dystrophy, an X-linked genetic disease, leads to progressive muscle weakness mainly in the lower limbs. Motor function tests help to monitor disease progression. Can low-cost, simple assessments help in the diagnostic suspicion of Duchenne muscular dystrophy? The authors aim to define the sensitivity of time to rise from the floor, time to walk 10 meters, and time to run 10 meters, evaluating them as eventual diagnostic screening tools. Methods: This is an analytical, observational, retrospective (1998-2015), and prospective study (2015-2018). Cases were recruited from the database of the pediatric neurology department and the healthy, from child care consultations, with normal gait development (up to 15 months) and without other comorbidities (neuromuscular, pulmonary, heart diseases) from the same university hospital. Results: 128 Duchenne muscular dystrophy patients and 344 healthy children were analyzed, equally distributed in age groups. In Duchenne muscular dystrophy, there is a progressive increase in the means of the times to perform the motor tests according to the age group, which accelerates very abruptly after 7 years of age. Healthy children acquire maximum motor capacity at 6 years and stabilize their times. The time to rise showed a p-value <0.05 and a strong association (effect size [ES] >0.8) in all age groups (except at 12 years), with time to walk 10 meters from 9 years, and with time to run 10 meters , from 5 years. The 100% sensitivity points were defined as follows: time to rise, at 2 s; time to walk 10 meters, 5 s; time to run 10 meters, 4 s. Conclusions: Time to rise is a useful and simple tool in the screening of neuromuscular disorders such as Duchenne muscular dystrophy, a previously incurable disease with new perspectives for treatment.


Resumo Objetivo: A distrofia muscular de Duchenne, doença genética ligada ao X, determina fraqueza muscular progressiva principalmente em membros inferiores. Os testes de função motora ajudam a monitorar a progressão da doença. Avaliações simples de baixo custo podem ajudar na suspeita diagnóstica da distrofia muscular de Duchenne? Objetivamos definir a sensibilidade do tempo levantar, tempo andar 10 metros e tempo correr 10 metros, avaliando-os como eventuais ferramentas de triagem diagnóstica. Métodos: Estudo analítico, observacional, retrospectivo (1998 até 2015) e prospectivo (2015 até 2018). Os casos foram recrutados do banco de dados do serviço de neurologia infantil e os saudáveis, de consultas de puericultura, com desenvolvimento de marcha normal (até os 15 meses) e sem outras comorbidades (neuromusculares, pneumopatias, cardiopatias), do mesmo hospital universitário. Resultados: Foram analisados 128 pacientes com distrofia muscular de Duchenne e 344 saudáveis, distribuídos igualmente em faixas etárias. Na distrofia muscular de Duchenne ocorre aumento progressivo das médias dos tempos para realizar as provas motoras, de forma acentuada a partir dos 7 anos. Os saudáveis estabilizam os tempos a partir dos 6 anos, adquirindo capacidade motora máxima. O tempo de levantar apresentou p-valor <0,05 e forte associação (TE >0,8) em todas as faixas etárias (exceto aos 12 anos), tempo de andar 10 metros a partir de 9 anos e o tempo de correr 10 metros, dos 5 anos. Os pontos de 100% sensibilidade foram definidos: tempo de levantar aos 2 segundos; tempo de andar, 5 segundos e tempo de correr 10 metros, 4 segundos. Conclusões: O tempo de levantar é útil e simples na triagem de doenças neuromusculares como a distrofia muscular de Duchenne, doença antes incurável com novas perspectivas de tratamento.

ABSTRACT

Las Miopatías Inflamatorias Idiopáticas (MII) son un grupo heterogéneo de enfermedades que se caracterizan por debilidad muscular e inflamación subyacente en la biopsia muscular. Los principales órganos afectados son el músculo, la piel y también puede afectarse el pulmón. Se distinguen dentro de los subtipos clínicos como Polimiositis (PM), Dermatomiositis (DM), DM con la variante Dermatomiositis Clínicamente Amiopática (DMCA), el Síndrome Antisintetasa (SAS), la Miositis Necrotizante Inmunomediada, la Miositis por Cuerpos de Inclusión (MCI) y la Miositis Asociada a Neoplasia. La presencia de ciertos anticuerpos específicos y asociados predispone al desarrollo de manifestaciones clínicas, determinando el pronóstico de la enfermedad. Se presentan 4 pacientes del Registro de MII de la Sociedad Argentina de Reumatología (SAR) con estas características: un paciente con PM y anti Jo-1 positivo y tres pacientes con DM (uno con DMCA y anti-RO 52 y dos pacientes con anti-PL7 y anti-TIF1γ respectivamente).


Idiopathic Inflammatory Myopathies (MII) are a heterogeneous group of diseases characterized by muscle weakness and inflammation underlying muscle biopsy. The main organs affected are muscle, skin and the lung can also be affected. They are distinguished within clinical subtypes such as Polymyositis (PM), Dermatomyositis (DM), DM with the variant Clinically Amiopathic Dermatomyositis (DMCA), the Syndrome Antisynthetase (SAS), Immune-mediated Necrotizing Myositis, Body Myositis Inclusion (MCI) and Neoplasia-Associated Myositis. The presence of certain specific and associated antibodies predisposes to the development of clinical manifestations, determining the disease prognosis. 4 patients from the Registry of MII of the Argentine Society of Rheumatology (SAR) are presented with these characteristics: one patient with PM and anti Jo-1 positive and three patients with DM (one with DMCA and anti-RO 52 and two patients with anti-PL7 and anti-TIF1γ respectively).

ABSTRACT

Abstract Duchenne muscular dystrophy (DMD) usually affects men. However, women are also affected in rare instances. Approximately 8% of female DMD carriers have muscle weakness and cardiomyopathy. The early identification of functional and motor impairments can support clinical decision making. Objective: To investigate the motor and functional impairments of 10 female patients with dystrophinopathy diagnosed with clinical, pathological, genetic and immunohistochemical studies. Methods: A descriptive study of a sample of symptomatic female carriers of DMD mutations. The studied variables were muscular strength and functional performance. Results: The prevalence was 10/118 (8.4%) symptomatic female carriers. Deletions were found in seven patients. The age of onset of symptoms in female carriers of DMD was quite variable. Pseudohypertrophy of calf muscles, muscular weakness, compensatory movements and longer timed performance on functional tasks were observed in most of the cases. Differently from males with DMD, seven female patients showed asymmetrical muscular weakness. The asymmetric presentation of muscle weakness was frequent and affected posture and functionality in some cases. The functional performance presents greater number of compensatory movements. Time of execution of activities was not a good biomarker of functionality for this population, because it does not change in the same proportion as the number of movement compensations. Conclusion: Clinical manifestation of asymmetrical muscle weakness and compensatory movements, or both can be found in female carriers of DMD mutations, which can adversely affect posture and functional performance of these patients.


Resumo A distrofia muscular de Duchenne (DMD) geralmente afeta indivíduos do sexo masculino. No entanto, mulheres também são acometidas em casos raros. Aproximadamente 8% das portadoras de DMD têm fraqueza muscular ou cardiomiopatia. A identificação precoce das alterações funcionais e motoras pode alterar a tomada de decisão clínica. Objetivo: Investigar as deficiências motoras e funcionais de 10 pacientes do sexo feminino com distrofinopatia diagnosticada por estudos clínicos, patológicos, genéticos e imuno-histoquímicos. Método: Estudo descritivo de uma amostra de portadoras sintomáticas de mutações DMD. As variáveis estudadas foram força muscular e desempenho funcional. Resultados: A prevalência foi de 10/118 (8,4%) de portadoras sintomáticas de DMD. Foram encontradas deleções em sete pacientes. A idade de início dos sintomas em portadoras de DMD foi variável. Pseudo-hipertrofia de panturrilhas, movimentos compensatórios, fraqueza muscular e aumento no tempo de execução de tarefas funcionais foram observados na maioria dos casos. Diferentemente dos homens com DMD, sete pacientes apresentaram fraqueza muscular assimétrica. A apresentação assimétrica da fraqueza muscular foi frequente, podendo afetar a postura e a funcionalidade. O desempenho funcional geralmente apresenta aumento no número de movimentos compensatórios. Não podemos sempre considerar o tempo como um bom marcador de funcionalidade para essa população, uma vez que não muda na mesma proporção que o número de compensações em todas essas pacientes. Conclusão: Fraqueza muscular assimétrica e movimentos compensatórios, ou ambos, podem ser encontrados em portadoras sintomáticas de DMD, o que pode afetar a postura e a funcionalidade dessas pacientes.

ABSTRACT

ABSTRACT The yellow fever is a systemic disease that was under control due to the effective campaigns against the vector and promotion of vaccines programs. However, since 1999, outbreaks appeared because of inefficient control of the vector, and led to the need of amplifying the immunization in large scale against the yellow fever virus, and consequently, raising the risk of adverse reactions to the vaccine. We report a case of previously healthy infant, who was referred to our care service, after 3 days with fever, chills, nausea and vomits, he received support therapy and was discharged from the hospital. After 24 hours of supportive measures, he was discharge. The patient returned to our service with general condition decline, strabismus, inability to control of cervical musculature and reduced force of the legs. The patient vaccine had received all vaccines from the calendar, and he was vaccinated for yellow fever 20 days before symptoms. During the hospitalization, liquor was collected, and ceftriaxone and aciclovir were administered. After negative cultures from the liquor, the antibiotics were suspended. The computed tomography of patient's brain showed no alterations. Research for antibodies against yellow fever was requested, being positive for IgM in the liquor, and confirming the neurotropic disease associated with the yellow fever vaccine. On the fifth day of hospitalization, the patient showed improvement on the strabismus, cervical tonus, and musculature force. On the tenth day of hospitalization, patient showed complete improvement, and his laboratory exams no alterations. Subsequently, patient was discharged. The vaccine against yellow fever is safe, efficient and highly recommended, however it is not completely free from serious adverse reactions, including death.


RESUMO A febre amarela é uma doença sistêmica que estava controlada graças às efetivas campanhas de combate ao vetor e aos programas de vacinação. Porém, desde 1999, os surtos reiniciaram-se, devido à ineficácia do controle do vetor, levando à necessidade da imunização em larga escala contra o vírus da febre amarela, gerando aumento do risco de ocorrência de reação adversa à vacina. O presente estudo se propôs a relatar o caso de um lactente previamente saudável, que procurou pronto atendimento, pois, há 3 dias, apresentava febre, calafrios, náusea e vômitos. Em 24 horas após medidas de suporte e alta, evoluiu com queda do estado geral, estrabismo, falta de controle da musculatura cervical e redução da força muscular de membros inferiores. O caderno vacinal encontrava-se completo, tendo recebido vacina contra febre amarela há 20 dias. Durante a internação, foi realizada coleta do liquor, e foram administrados ceftriaxona e aciclovir. Após cultura negativa do liquor, o antibiótico foi suspenso. A tomografia computadorizada de crânio não apresentou alterações. Solicitou-se pesquisa de anticorpos contra o vírus da febre amarela no liquor, sendo positiva para IgM e confirmando a doença neurotrópica associada à vacina da febre amarela. A partir do quinto dia de internação, o paciente evoluiu com melhora do estrabismo, do tônus cervical e da força muscular. No décimo dia de internação, apresentou melhora completa do quadro, sem alterações laboratoriais, recebendo alta. A vacina contra febre amarela é segura, eficaz e fortemente recomendada, porém não está completamente isenta de reações adversas graves, inclusive podendo levar a quadros fatais.

ABSTRACT

PURPOSE: Patients with secondary hyperparathyroidism are at high risk for developing postoperative hypocalcemia. However, there are limited data regarding predictors of postoperative hypocalcemia in renal failure patient with secondary hyperparathyroidism. This study aimed to determine the clinical presentations of renal hyperparathyroidism and the predictors of early postoperative hypocalcemia after total parathyroidectomy.METHODS: Data of patients with renal hyperparathyroidism who underwent total parathyroidectomy between January 2007 to December 2014 were reviewed retrospectively. Patients were divided into 2 cohort groups according to their serum calcium levels within 24 hours of parathyroidectomy: the hypocalcemia group (calcium levels of 2 mmol/L or less), and the normocalcemia group (calcium levels more than 2 mmol/L). With the use of multivariable logistic regression analyses, the predictors of early postoperative hypocalcemia after total parathyroidectomy in patients with renal hyperparathyroidism were investigated.RESULTS: Among 68 patients, 56 patients (82.4%) were symptomatic preoperatively. Fifty patients (73.5%) presented with bone pain and 14 patients (20.6%) had muscle weakness. Early postoperative hypocalcemia occurred in 25 patients (36.8%). Preoperative alkaline phosphatase level was the predictor of early postoperative hypocalcemia (adjusted odds ratio, 1.004; 95% confidence interval, 1.001–1.006; P = 0.002).CONCLUSION: Results from our study show that most of the patients with renal hyperparathyroidism were symptomatic preoperatively and the most common clinical presentations were bone pain and muscle weakness. The significant predictor of early postoperative hypocalcemia after total parathyroidectomy was the preoperative alkaline phosphatase levels.

ABSTRACT

INTRODUCCIÓN. En el paciente crítico ha existido un conglomerado de situaciones dadas por alteración de las hormonas acorde al comportamiento del eje hipotalámi-co-hipofisario- gonadal, entender su rol es fundamental. OBJETIVO. Describir las alteraciones de las hormonas sexuales en el paciente críticamente enfermo desde un enfoque fisiológico y clínico. MATERIALES Y MÉTODOS. Estudio observacional, de revisión bibliográfica y análisis sistemático de 84 artículos científicos y selección de muestra de 27 en MedLine, The Cochrane Library Plus, LILACS y Web of Science; en español e inglés y variables: hormonas esteroides gonadales, enfermedad crítica, endocrinología, estrés, gónadas y disfunción, periodo 1998-2017. CONCLUSIÓN. Las alteraciones detectadas fueron un mecanismo para la producción de hormonas esteroideas hacia la síntesis predominante de cortisol y soportar el alto estrés meta-bólico de los pacientes. Las citocinas pro inflamatorias fueron importantes en éstos cambios. La polifarmacia fue un factor adicional poco ponderado de la alteración endocrina sexual.


INTRODUCTION. In the critical patient there has been a conglomerate of situations given by alteration of the hormones according to the behavior of the hypothalamic-pi-tuitary-gonadal axis, understanding their role is fundamental. OBJECTIVE. Describe the alterations of sex hormones in the critically ill patient from a physiological and clinical approach.MATERIALS AND METHODS.Observational, literature review and systematic analysis of 84 scientific articles and sample selection of 27 in MedLine, The Cochrane Library Plus, LILACS and Web of Science; in Spanish and English and variables: gonadal steroid hormones, critical illness, endocrinology, stress, gonads and dysfunction, period 1998-2017. CONCLUSION. The alterations detected were a mechanism for the production of steroid hormones towards the predominant syn-thesis of cortisol and withstand the high metabolic stress of the patients. Pro inflam-matory cytokines were important in these changes. Polypharmacy was an additional unweighted factor of sexual endocrine disruption.

ABSTRACT

RESUMO Objetivo: Caracterizar os pacientes com doença crítica crônica e identificar os preditores relacionados à evolução para doença crítica crônica. Métodos: Coleta prospectiva de dados por 1 ano realizada na unidade de terapia intensiva de um hospital geral localizado na Região Sul do país. Construíram-se três modelos de regressão logística para identificar os fatores associados com doença crítica crônica. Resultados: Dentre os 574 pacientes admitidos à unidade de terapia intensiva durante o período do estudo, 200 foram submetidos à ventilação mecânica. Destes, 85 (43,5%) pacientes desenvolveram doença crítica crônica, totalizando 14,8% de todos os pacientes admitidos à unidade de terapia intensiva. O modelo de regressão que avaliou os fatores prévios à admissão à unidade de terapia intensiva associados com doença crítica crônica identificou insuficiência renal crônica submetida à diálise (OR 3,57; p = 0,04) e diagnóstico neurológico quando da admissão ao hospital (OR 2,25; p = 0,008) como fatores independentes. No modelo que avaliou a associação de doença crítica crônica com situações ocorridas durante a permanência na unidade de terapia intensiva, destacaram-se fraqueza muscular (OR 2,86; p = 0,01) e úlceras por pressão (OR 9,54; p < 0,001). Na análise multivariada global (fatores prévios e situações ocorridas durante a permanência na unidade de terapia intensiva), destacaram-se admissão ao hospital por doenças neurológicas (OR 2,61; p = 0,03) e desenvolvimento de úlceras por pressão (OR 9,08; p < 0,001). Conclusão: A incidência de doença crítica crônica foi similar à observada em outros estudos e teve associação mais forte com o diagnóstico de doenças neurológicas quando da admissão ao hospital e insuficiência renal crônica submetida à hemodiálise, assim como com complicações desenvolvidas durante a hospitalização, como úlceras por pressão e fraqueza muscular.


ABSTRACT Objective: To characterize patients with chronic critical illness and identify predictors of development of chronic critical illness. Methods: Prospective data was collected for 1 year in the intensive care unit of a general hospital in Southern Brazil. Three logistic regression models were constructed to identify factors associated with chronic critical illness. Results: Among the 574 subjects admitted to the intensive care unit, 200 were submitted to mechanical ventilation. Of these patients, 85 (43.5%) developed chronic critical illness, composing 14.8% of all the patients admitted to the intensive care unit. The regression model that evaluated the association of chronic critical illness with conditions present prior to intensive care unit admission identified chronic renal failure in patients undergoing hemodialysis (OR 3.57; p = 0.04) and a neurological diagnosis at hospital admission (OR 2.25; p = 0.008) as independent factors. In the model that evaluated the association of chronic critical illness with situations that occurred during intensive care unit stay, muscle weakness (OR 2.86; p = 0.01) and pressure ulcers (OR 9.54; p < 0.001) had the strongest associations. In the global multivariate analysis (that assessed previous factors and situations that occurred in the intensive care unit), hospital admission due to neurological diseases (OR 2.61; p = 0.03) and the development of pressure ulcers (OR 9.08; p < 0.001) had the strongest associations. Conclusion: The incidence of chronic critical illness in this study was similar to that observed in other studies and had a strong association with the diagnosis of neurological diseases at hospital admission and chronic renal failure in patients undergoing hemodialysis, as well as complications developed during hospitalization, such as pressure ulcers and muscle weakness.

ABSTRACT

INTRODUÇÃO: A reabilitação pulmonar (RP) vem sido descrita como uma forma de tratamento para pacientes com doença pulmonar obstrutiva crônica (DPOC), tendo o treino resistido como seu principal componente. Apesar de estar clara na literatura a importância e reais benefícios adquiridos com programa de reabilitação, este muitas vezes só é iniciado após a alta hospitalar, adiando os potenciais efeitos e intensificando o comprometimento funcional do paciente. OBJETIVO: Revisar sistematicamente as publicações presentes na literatura relacionados aos efeitos do treino resistido sobre a capacidade funcional de pacientes com DPOC, considerando a viabilidade, segurança e características da prescrição do exercício durante o processo de reabilitação. MATERIAIS E MÉTODOS: Trata-se de um estudo de revisão sistemática (CRD42020158760) sobre os efeitos do treino resistido sobre a capacidade funcional de pacientes com DPOC. Foram selecionados artigos científicos no período de setembro de 2018 a fevereiro de 2019 que continham os seguintes descritores: "DPOC", "treinamento de resistência", "fraqueza muscular", "hospitalização" e "hospital". RESULTADOS: Foram incluídos dois estudos nesta revisão sistemática atendendo aos critérios de elegibilidade. Ambos utilizaram como forma de avaliação da capacidade funcional o teste de caminhada de 6 minutos e obtiveram resultados favoráveis ao treinamento iniciado em ambiente hospitalar. CONCLUSÃO: O treinamento resistido foi capaz de melhorar a capacidade funcional refletindo sobre a melhora na realização de atividades de vida diária e qualidade de vida. Demonstrou ser segura, de viável implementação e sem riscos para eventos adversos.


INTRODUCTION: Pulmonary rehabilitation (PR) has been described as a form of treatment for patients with chronic obstructive pulmonary disease, with resistance training as its main component. Although the importance and real benefits of a rehabilitation program are clear in the literature, it is often only started after hospital discharge, postponing the potential effects and intensifying the patient's functional impairment. OBJECTIVE: Systematically review publications in the literature regarding the effects of resistance training on the functional capacity of patients with COPD, considering the feasibility, safety and characteristics of exercise prescription during the rehabilitation process. MATERIALS AND METHODS: This is a systematic review study (CRD42020158760) of the effects of resistance training on the functional capacity of patients with COPD. Scientific articles were selected from september 2018 to february 2019 that contained the following descriptors: "COPD", "resistance training", "muscle weakness", "hospitalization" and "hospital". RESULTS: Two studies were included in this systematic review meeting the eligibility criteria. Both used the 6-minute walk test as a means of assessing functional capacity and had favorable effects on training initiated in a hospital setting. CONCLUSION: Resistance training was able to improve functional capacity reflecting on the improvement in the performance of activities of daily living and quality of life. It has been shown to be safe, feasible to implement and without risk for adverse events.

ABSTRACT

OBJECTIVE: Respiratory muscle training has been considered one of the main strategies to alleviate sarcopenia in older adults. Therefore, the present study aimed to verify which respiratory muscle training protocols are most used in this population and their main benefits described in the literature. METHODS: A literature search was performed in the electronic databases PubMed, Latin American and Caribbean Health Sciences Literature (LILACS) and Scientific Electronic Library Online (SciELO). For this, we used the terms: respiratory muscle training, older adults, and muscle weakness. A total of 80 articles were studied, of which only 8 met the inclusion criteria of this study, whose methodology, variables studied, and outcome were analyzed. RESULTS: Among the 8 articles analyzed, we can observe an important diversity of the studied protocols; and all articles showed the most varied gains possible with respiratory muscle training. CONCLUSION: The protocols used in the various studies depend directly on the objective to be achieved with respiratory muscle training; and the main outcomes were improvements in strength, lung function, physical fitness level, quality of life, inflammatory markers and glucose intake.
