RESUMO

Lymphedema is a chronic and progressive disease characterized by fluid accumulation, causing tissue edema as a result of a compromised lymphatic system. Diagnostic ultrasound (DUS) is a method capable of assessing soft tissue characteristics that can be used reliably to diagnose lymphedema as well as for measuring tissue compliance in a clinical setting. This is a systematic review, aiming to evaluate articles that made use of DUS in management of lymphedema secondary to breast cancer. A total of 570 articles were selected, exported to the Rayyan QCRI review program, and then screened by two researchers. From this search, 25 articles were selected after the authors reached consensus and were catalogued as to their main results. Diagnostic ultrasound was identified as an advantageous method that is safe, minimally invasive, low cost, and radiation free and is useful for evaluating the efficacy of therapies used in lymphedema treatment.

RESUMO

Resumo O linfedema é uma doença crônica e progressiva caracterizada pelo acúmulo de fluidos, provocando edema tecidual em decorrência de um sistema linfático comprometido. A ultrassonografia diagnóstica (USD) é um método capaz de avaliar as características dos tecidos moles, podendo ser utilizada de maneira confiável para o diagnóstico do linfedema, além de mensurar a complacência tecidual em um cenário clínico. Esta é uma revisão sistemática, objetivando avaliar artigos que fizessem o uso da USD na abordagem do linfedema secundário ao câncer de mama. Foram selecionados 565 artigos, que foram exportados para o programa de revisão Rayyan QCRI e, em seguida, triados por dois pesquisadores. Dessa busca, foram obtidos 25 artigos selecionados após consenso entre os autores e que foram catalogados quanto aos seus resultados principais. A USD foi identificada como um método vantajoso por ser seguro, pouco invasivo, de baixo custo, sem uso de radiação, além de ser útil para avaliar a eficácia de terapias no tratamento do linfedema.

RESUMO

Introduction: Transcutaneous electrical nerve stimulation (TENS), interferential current therapy (IFC) and photobiomodulation therapy (PBMT) have been used in the management of cancer-related pain in adults. However, there are still some controversy regarding the effects of this therapy on tumor cells that may remain after cancer treatment. Objective: To evaluate the risk of recurrence of breast cancer in rats when using TENS, IFC or PBMT. Method: An experimental, randomized, controlled and cross-sectional study. With 90 days of age, 7,12-dimetylbenz(a)anthracene (7,12-DMBA) was administered to rats by gastric gavage to induce mammary cancer. After 120 days the mammary glands of the rats belonging to the group with mammary cancer were removed. Results: 39 female Sprague-Dawley rats were studied: 9 rats without induction of mammary carcinoma; 9 rats with induction of mammary carcinoma and without surgery; 9 rats with induction of mammary carcinoma with surgery and placebo application of TENS, IFC, PBMT; 9 rats with induction of mammary carcinoma, surgery and the application of TENS, IFC and PBMT. Conclusion: This study demonstrated that there was local recurrence of tumors in rats that were stimulated with TENS or IFC, however no evidence of local recurrence with PBMT

RESUMO

The mobile phone has been part of daily activities and offers various facilities for the elderly. Like other conveniences of modern life their use may have some effects that should be explored. Objective: To investigate the effect of cell phones on the functional mobility of adults (GA) and the elderly (GI). Method: 30 elderly, 70.96 ± 5.17 years old and 30 adults 23 ± 2.26 years old participated in this study. They were evaluated by MMSE, FES-I and TUG which was collected during the execution of 5 tasks (1 simple TUG, 2 TUG typing on the cell phone, 3 TUG answering questions on the cell phone, 4 TUG naming the days of the week in reverse, 5-TUG holding a glass with water). Results: There was a difference between the groups in FES-I (p = 0.001) and TUG in all analyzed tasks (p = 0.00001). The dual task (DT) of typing on the cell phone was the one that most affected the performance of the elderly in TUG (p = 0.00008) followed by DT 4 (conventional cognitive) p = 0.005 and DT 3 (p = 0.004). There was no effect of DT 5 (motor) (p = 0.03). For GA there was only effect of DT 2 (p = 0.027). Conclusion: Cellular use negatively impacted the performance of the elderly and can be considered a more realistic DT. The distraction generated by this task can increase the risk of falling and should be considered in preventive campaigns as well as rehabilitation programs.

Como outras conveniências da vida moderna seu uso pode apresentar alguns efeitos que devem ser explorados. Objetivo: Investigar o efeito do celular na mobilidade funcional de adultos (GA) e idosos (GI). Método: Participaram deste estudo 30 idosos, 70,96 ± 5,17 anos e 30 adultos 23±2,26 anos. Foram avaliados pelo MEEM, FES-I e TUG que foi coletado durante a execução de 5 tarefas (TUG 1 simples, TUG 2 dupla tarefa (DT) digitando ao celular, TUG 3 DT respondendo perguntas ao celular, TUG 4 DT nomeando os dias da semana ao contrário, TUG 5 DT segurando um copo com água). Resultados: Houve diferença entre os grupos na FES-I (p=0,001) e no TUG em todas as tarefas analisadas (p=0,00001). A DT de digitar ao celular foi a que mais afetou o desempenho dos idosos no TUG (p=0,00008) seguida pela DT 4 (cognitiva convencional) p= 0,005 e DT 3 (p=0,004). Não houve efeito da DT 5 (motora) (p=0,03). Para o GA só houve efeito da DT 2 (p=0,027). Conclusão: O uso do celular impactou de forma negativa a performance de idosos e pode ser considerado uma DT mais realista. A distração gerada por esta tarefa pode aumentar o risco de queda e deve ser considerada em campanhas preventivas assim como programas de reabilitação.

RESUMO

Abstract Objective: To evaluate the effect of vestibular manipulation on the postural sway and muscle activation of younger and older adults. Methods: The study analyzed the effects of three intensity levels of galvanic vestibular stimulation (GVS) (0.3; 0.6 and 1m) on the pattern of muscle activity and center of pressure (CP) displacements of 12 older adults (EG) and 12 young adults (CG) while maintaining their balance on a stable surface, with no vision. Results: The EG showed a positive correlation between CP displacement and muscle activity and GVS intensity. On the other hand, the magnitude of postural response in the EG was not modulated in accordance with GVS intensities. Additionally, during the highest GVS intensity level (1 mA) greater muscle activity was used to increase stiffness, decrease the amplitude of oscillation and ensure stability. This unusual response characterizes a pattern of co-activation and is perhaps a safety mechanism to ensure stability. Conclusion: The EG individuals were not able to select the appropriate motor strategy to efficiently compensate the effects of GVS. This unusual strategy reflects deficits in the vestibular system of older adults, a fact which negatively interferes with their ability to reevaluate sensory information.

Resumo Objetivo: Avaliar a interferência da manipulação das informações vestibulares na oscilação postural e atividade muscular de jovens e idosos. Métodos: Foi analisado o efeito de três intensidades (0,3; 0,6 e 1mA) de estimulação vestibular galvânica (GVS) no padrão de ativação muscular e deslocamento do centro de pressão (CP) de 12 idosos (GI) e 12 adultos jovens (GC), durante a manutenção do equilíbrio em uma superfície estável sem visão. Resultados: O GC mostrou correlação positiva entre o deslocamento de CP e a ativação muscular com a intensidade da GVS. Por outro lado, o GI não foi capaz de modular a magnitude da resposta postural com a intensidade da GVS. Durante o maior valor de GVS (1mA), houve um aumento da ativação muscular de agonista e antagonista caracterizando um padrão de coativação que aumentou a rigidez e diminuiu a amplitude de oscilação. Conclusão: Os indivíduos do GI selecionaram uma estratégia motora atípica para compensar os efeitos da GVS. Essa estratégia incomum refletiu deficit no sistema vestibular dos idosos e pode interferir negativamente na capacidade de reorganização das informações sensoriais.

RESUMO

A pesquisa objetivou compreender as significações de crianças de um assentamento rural vinculado ao MST, na região de Ribeirão Preto-SP, acerca de um espaço/tempo especificamente a elas destinado, denominado Ciranda Infantil. Utilizamos como instrumentos diário de campo, fotografias realizadas pelas crianças, conversas baseadas em fotografias, fantoches. Participaram seis crianças de 10 a 12 anos. Os resultados indicam que a Ciranda tem sido significada pelas crianças como um espaço de socialização e aprendizagens variadas entre adultos e crianças, marcadas pela construção de relações afetivas, socioambientais e geracionais, com destaque para a ludicidade. Conclui-se que as crianças percebem que existe para elas um projeto intencional e apropriam-se desse espaço como sujeitos críticos que colaboram em sua construção e, ou, disputam-no com os adultos. Esse sentimento de ter a Ciranda como espaço próprio os autoriza a propor melhorias para sua realização.

This research aimed to understand the meanings yielded by children of a rural settlement linked to the Landless Workers’ Movement (MST), in the region of Ribeirão Preto (SP, Brazil), about a space/time assigned specifically to them, called Children’s Ciranda. As methodological instruments, we used field diary, photographs taken by the children; conversations based on the photographs; and puppets. Six children aged from ten to twelve years participated. The results indicate that "Ciranda" has been signified by children as a space of socialization and varied learnings among adults and children, marked by the construction of affective, socio-environmental and generational relations, highlighting playfulness. We conclude that children realize that there is an intentional project for them and they take property of this space as critical subjects who collaborate in its construction and / or compete with adults. This feeling of having the “Ciranda” as their own space authorizes them to propose improvements to its realization.

RESUMO

Recent studies show that low-level laser therapy (LLLT) has an important anti-inflammatory action in acute lung inflammation. The present work explored if laser therapy is able to antagonize eosinophils and allergic inflammation induced by oxidative stress in Balb/c mice. Forty-eight hours after challenge, the leukocyte counting, ROS and nitrite/nitrate level, RANTES, CCL3, CCL8 as well as eotaxins were measured in the bronchoalveolar lavage fluid (BALF) of laser-treated mice or not. Into the lung, some chemokines receptors, the iNOS activity and mRNA expression, and the activities of superoxide dismutase (SOD), catalase, gluthatione, NADPH oxidase activities and thiobarbituric acid reactive species (T-Bars) were measured. Laser-treated allergic mice presented reduction of both the ICAM-1 and eosinophil in the lungs. RANTES, CCL8, CCL3 and eotaxins were reduced in BALF of laser-treated allergic mice. In allergic mice lung LLLT decreased the CCR1 and CCR3 and restored the oxidative stress balance as well. Laser decreased the lipidic peroxidation in allergic mice lung as much as increased SOD, GPx and GR. It shows that LLLT on allergic lung inflammation involves leukocyte-attractant chemokines and endogenous antioxidant. Based on results, LLLT may ultimately become a non- invasive option in allergic lung disease treatment. The top figure illustrates the laser decreasing the eosinophils migration into BALF and the bottom figure shows the laser upregulating the expression of heme-oxygenase (anti-oxidant enzyme) in lung tissue anti-oxidant.

RESUMO

BACKGROUND: muscle strength and power are two factors affecting balance. The impact of muscle strength and power on postural control has not been fully explored among different age strata over sixty. OBJECTIVES: the aim of the present study was to assess the muscle strength and power of elderly women in different age groups and determine their correlation with postural control. METHOD: eighty women were divided into four groups: the young 18-30 age group (n=20); the 60-64 age group (n=20); the 65-69 age group (n=20); and the 70-74 age group (n=20). The participants underwent maximum strength (one repetition maximum or 1-RM) and muscle power tests to assess the knee extensor and flexor muscles at 40%, 70%, and 90% 1-RM intensity. The time required by participants to recover their balance after disturbing their base of support was also assessed. RESULTS: the elderly women in the 60-64, 65-69, and 70-74 age groups exhibited similar muscle strength, power, and postural control (p>0.05); however, these values were lower than those of the young group (p<0.05) as expected. There was a correlation between muscle strength and power and the postural control performance (p<0.05). CONCLUSION: despite the age difference, elderly women aged 60 to 74 years exhibited similar abilities to generate strength and power with their lower limbs, and this ability could be one factor that explains the similar postural control shown by these women.

RESUMO

INTRODUCTION: The increase in the number of studies has led to greater security in the application of this method and the determination of its effectiveness in adults.. The purpose of the present study was to evaluate heart rate variability in healthy individuals submitted to different levels of positive expiratory pressure using an expiratory positive airway pressure (EPAP) device. MATERIAL AND METHODS: The study involved 27 healthy male individuals ranging in age from 20 to 35 years. Patient histories were taken and the subjects were submitted to a physical examination. The volunteers were monitored using the Polar 810s(®) and submitted to the EPAP experiment. Analyses were performed on variables of the frequency domain. Sympathetic and parasympathetic bands and their relationship with sympathovagal response were also analyzed. RESULTS: The mean value of this variable was 526.89 (55.50) ms(2) in the first period, 2811.0 (721.10) ms(2) in the fourth period and 726.52 (123.41) ms(2) in the fifth period. Regarding the parasympathetic area, significant differences were detected when Periods 1 and 5 (no load) were compared with periods in which the individuals were subjected to the use of the therapy. Sympathetic and parasympathetic areas together, a significant difference was detected regarding the sympathetic/parasympathetic ratio in the comparison between Periods 1 and 4 (p < 0.01) as well as Periods 2 and 4 (p < 0.05). CONCLUSIONS: The findings of the present study suggest that the therapeutic use of EPAP significantly alters the parameters of heart rate variability in the frequency domain, highlighting the importance of monitoring and care during the practice of EPAP.

RESUMO

BACKGROUND: Studies have demonstrated the beneficial effects of topical application of fatty acids as healing agents. The lipid fraction of Ovis aries have an anti-inflammatory action that accelerates the healing process. Ultrasound increases blood flow and the extensibility of collagen structures and tendons. OBJECTIVES: To assess the anti-inflammatory action of the Ovis aries lipid fraction associated to pulsed therapeutic ultrasound and friction in an induced tendinitis model. METHODS: Fifty Wistar rats were divided into four groups: control that consisted of Ovis aries gel for topical use; pulsed ultrasound plus oil free sterile lotion; pulsed ultrasound plus Ovis aries gel; and oil free sterile lotion for topical use alone. To induce tendinitis a 10 µL intratendinous injection of collagenase was injected into the right Achilles tendon of rats. Treatment consisted of daily applications of ultrasound using the following parameters: 10% pulsed mode, 10% pulsed frequency of 1 MHz and intensity of 0.5 W/cm² for seven or fourteen days. RESULTS: After 7 days of treatment, only the Ovis aries plus ultrasound group showed statistically significant difference when compared to the control group.The variation in the number of inflammatory cells on animals treated for fourteen days for the control, ultrasound plus oil free, ultrasound plus Ovis aries, Ovis aries plus massage and massage plus oil free groups were statistically significant different, p<0.01. It was observed in animals treated for seven days that the ultrasound plus Ovis aries group was statistically significant better than the control group, p<0.05. CONCLUSION: It can be concluded that treatment using ultrasound plus Ovis aries is more effective than other treatments as it produces significantly better reduction on the number of inflammatory cells at 7 and 14 days.

RESUMO

The main physiological characteristics in a burn process are the increase of the capillary permeability and the occurrence of edema and exudation. Light-emitting diode (LED) has been proposed as treatment of burning. This study investigated the effects of LED on the repair process of rat skin submitted to a third-degree burning. The lesions were produced on the dorsal surface of male Wistar rats. Animals were divided into 4 groups (n = 6) as follows: L1 and L2 groups as LED-treated burned rats, and received LED therapy along 7 and 15 days with 48 hours intervals, respectively; C1 and C2 groups as control, non-treated burned rats. A red LED (640 nm, 30 mW) operating with a fluence of 4 J/cm(2) was used. The wound area was measured daily after irradiation. Animals were euthanized at the 8th and 16th days after burning, and the wound fragment was submitted to histology. The inflammatory cells as well as the damaged area at the 8th day after burns were significantly lower for the LED-treated group when compared to control. Furthermore, the LED phototherapy effect on cellular migration was even more pronounced at the 16th day. Our results indicated that the treatment with a LED system was clearly effective in reducing the number of inflammatory cells and improving the healing process in an experimental model of third-degree burnings.

RESUMO

CONTEXTUALIZAÇÃO: Estudos demonstram o efeito benéfico da aplicação tópica de ácidos graxos como agentes cicatrizantes. A fração lipídica do Ovis aries apresenta uma ação anti-inflamatória que acelera o processo de cicatrização. O ultrassom aumenta o fluxo sanguíneo bem como a extensibilidade das estruturas de colágeno e tendões. OBJETIVOS: Analisar a ação anti-inflamatória da fração lipídica do Ovis aries associado ao ultrassom terapêutico (UST) pulsado e à fricção em modelo de tendinite induzida. MÉTODOS: Cinquenta ratos Wistar foram distribuídos nos seguintes grupos: controle, gel Ovis aries - uso tópico - UST pulsátil + loção estéril (oil free), UST pulsátil + gel Ovis aries, loção estéril (oil free) - uso tópico. Para induzir a tendinite, utilizou-se uma injeção intratendínea de 10µL de colagenase no tendão do calcâneo direito. O tratamento consistiu em aplicações diárias de ultrassom, com os seguintes parâmetros: modo pulsado 10 por cento, frequência de 1 MHz, pulsátil a 10 por cento com intensidade de 0,5W/cm², durante sete ou 14 dias. RESULTADOS: A variação do número de células inflamatórias, para os animais tratados por 14 dias, com relação aos grupos controle, UST + oil free e UST + Ovis aries, apresentou resultados significativos p<0,001. O grupo Ovis aries + massagem e o grupo massagem + oil free apresentaram resultados significativos, p<0,01. Nos animais tratados por sete dias, observou-se que o grupo UST + Ovis aries, em relação ao controle, é estatisticamente significativo, p<0,05 CONCLUSÃO: Pode-se concluir que o tratamento com UST + Ovis aries é mais efetivo que os outros tratamentos, visto que consegue reduzir o número de células inflamatórias no tempo de sete e 14 dias.

BACKGROUND: Studies have demonstrated the beneficial effects of topical application of fatty acids as healing agents. The lipid fraction of Ovis aries have an anti-inflammatory action that accelerates the healing process. Ultrasound increases blood flow and the extensibility of collagen structures and tendons. OBJECTIVES: To assess the anti-inflammatory action of the Ovis aries lipid fraction associated to pulsed therapeutic ultrasound and friction in an induced tendinitis model. METHODS: Fifty Wistar rats were divided into four groups: control that consisted of Ovis aries gel for topical use; pulsed ultrasound plus oil free sterile lotion; pulsed ultrasound plus Ovis aries gel; and oil free sterile lotion for topical use alone. To induce tendinitis a 10µL intratendinous injection of collagenase was injected into the right Achilles tendon of rats. Treatment consisted of daily applications of ultrasound using the following parameters: 10 percent pulsed mode, 10 percent pulsed frequency of 1 MHz and intensity of 0.5 W/cm² for seven or fourteen days. RESULTS: After 7 days of treatment, only the Ovis aries plus ultrasound group showed statistically significant difference when compared to the control group.The variation in the number of inflammatory cells on animals treated for fourteen days for the control, ultrasound plus oil free, ultrasound plus Ovis aries, Ovis aries plus massage and massage plus oil free groups were statistically significant different, p<0.01. It was observed in animals treated for seven days that the ultrasound plus Ovis aries group was statistically significant better than the control group, p<0.05. CONCLUSION: It can be concluded that treatment using ultrasound plus Ovis aries is more effective than other treatments as it produces significantly better reduction on the number of inflammatory cells at 7 and 14 days.

RESUMO

Introdução: O acidente vascular cerebral é a doença neurológica que mais frequentemente acomete o sistema nervoso e é a principal causa de incapacidades físicas e mentais. Objetivo: Avaliar o comportamento motor em modelos de animais após cirurgia de oclusão da carótida comum. Método: Foram utilizados 16 ratos Wistars, e foi realizado cirurgia anteriormente na cervical para exposição da carótida comum, sendo obstruída por pinça hemostática. A amostra foi dividida em dois grupos, GI e GII Resultados: Na análise estatística, os valores da média e desvio-padrão para a reação normal foi de 42,5±0,70 e para a reação de flexão 0,0±0,0 para o Grupo I. Para o grupo II, a média e o desvio-padrão para reação normal foi de 36,0±1,41 e para a reação de flexão, de 20,0±2,82. Conclusão: A atividade física é essencial para o dia a dia em pacientes portadores de lesão neurológica, proporcionando melhora locomotora.

Introduction: The stroke is a neurological disease that most commonly affects the nervous system and is the leading cause of mental and physical disabilities. Objective: To evaluate motor behavior in animal models after coronary occlusion of the common carotid. Method: 16 Wistar rats, and surgery was performed earlier in the neck to expose the common carotid artery, being obstructed by a hemostat. The sample was divided into two groups GI and GII Results: Statistical analysis, the mean and standard deviation for the normal reaction was 42.5 ± 0.70 and for the reaction of flexion 0.0 ± 0, 0 for Group I. In group II, the mean and standard deviation for normal reaction was 36.0 ± 1.41 and for the reaction of flexion, 20.0 ± 2.82. Conclusion: Physical activity is essential for daily life in patients with neurological injury and improved the locomotor activity.
