Objetivo: A pesquisa tem por objetivo verificar os limiares de repouso eletromiográfico dos músculos masseter e temporal em pacientes com disfunção temporomandibular (DTM) antes e após intervenção fonoaudiológica com e sem a utilização de bandagem elástica terapêutica. Métodos: A coleta contou com 14 participantes do sexo feminino, com idade entre 18 e 40 anos, com diagnóstico de DTM muscular ou mista. As pacientes foram divididas entre dois grupos classificados em: pacientes com bandagem associada à terapia tradicional (CB) e grupo de terapia tradicional (SB). As pacientes inicialmente foram avaliadas pelo exame de eletromiografia de superfície nas situações de contração voluntária máxima e repouso, e após quatro semanas de intervenção, foi realizada nova avaliação com os mesmos instrumentos. A análise dos dados ocorreu de forma quantitativa e qualitativa. Resultados:No grupo SB o músculo masseter direito apresentou aumento dos valores de repouso com significância, foi observado que o mesmo ocorreu para todos os músculos deste grupo, influenciando no equilíbrio da musculatura ipsilateral e contralateral, no entanto sem evidência estatística. O grupo CB não demonstrou valores estatísticos significativos, porém qualitativamente os valores de repouso muscular diminuíram e equilibraram-se de forma contralateral. Conclusão: Não foram observadas mudanças estatisticamente significantes nos limiares eletromiográficos durante repouso dos músculos masseter e temporal em ambos os grupos. Qualitativamente houve aumento dos valores eletromiográficos após terapia manual tradicional em todos os músculos do grupo SB. Com relação ao grupo CB, houve diminuição dos valores do repouso eletromiográfico após terapia, embora sem evidências estatísticas. (AU)

Purpose: Objective: The research aims to verify the electromyographic rest thresholds of the masseter and temporal muscles in patients with temporomandibular disorders (TMD) before and after speech therapy intervention with and without the use of therapeutic elastic bandage. Methods: The collection included 14 female participants, aged between 18 and 40 years, who had a diagnosis of muscular or mixed TMD. The patients were divided into two groups: with traditional therapy (CB) bandage and traditional therapy (SB) only group. The patients underwent initial evaluation, as well as surface electromyography in situations of maximum voluntary contraction and rest and at the end of the four weeks of intervention, a new evaluation was performed with the same instruments. Data analysis occurred quantitatively and qualitatively. Results: In the SB group, the right masseter muscle showed a significant increase in resting values. It was observed that the same occurred for all muscles in this group, influencing the balance of the ipsilateral and contralateral muscles, although without statistical evidence. The CB group did not show statistically significant values, but qualitatively the muscle rest values decreased and balanced in a contralateral way. Conclusion: No statistically significant changes were observed in the resting electromyographic thresholds of the masseter and temporalis muscles in both groups. Qualitatively, there was an increase in electromyographic values after traditional manual therapy in all muscles in the SB group. Regarding the CB group, there was a decrease in electromyographic resting values after therapy, although without statistical evidence. (AU)

Processos de reflexividade dos psicólogos do esporte e coaches: um estudo fenomenológico / Reflexivity processes of sport psychologists and coaches: a phenomenological study / Procesos de reflexividad de psicólogos del deporte y coaches: un estudio fenomenológico

O objetivo desta pesquisa é identificar e compreender fenomenologicamente, por meio de relato de Psicólogos de Esporte (PE) e de Coaches, em sua vivência prática, como ocorrem os processos reflexivos em sua atuação, conforme apreendidos a partir de relatos de experiências. O método de investigação escolhido foi a fenomenologia, pois oferece os recursos necessários para tal mergulho junto à experiência reflexiva. A amostra intencional foi delineada por PE e Coaches (profissionais de Educação Física que recorrem ao Coaching) em atividade em esportes de alto rendimento, que tenham atuado ou estejam atuando em modalidades esportivas coletivas e/ou individuais. Realizaram-se nove entrevistas (cinco com PE, quatro com Coaches). O acesso ao objeto desse estudo se deu por meio de entrevistas em profundidade e semiestruturadas, orientadas pela escuta suspensiva. As questões disparadoras foram formuladas com base no Procedimento Estruturado de Reflexão adaptado. Para análise das entrevistas, realizou-se uma síntese de cada relato, seguindo-se de cruzamento intencional. Como resultados, percebeu-se que PE e Coaches trazem algumas similaridades no que se refere aos modos de refletir sobre sua prática. No entanto, as experiências que eles fazem desses processos reflexivos é que podem tomar rumos distintos. Os(as) PE amparam-se na regulamentação da profissão e resguardam-se em seus apontamentos, trazendo suas experiências e reflexões sobre os processos vividos. Os(as) Coaches trazem em suas explanações um trabalho coerente, organizado e compatível com o método do Coaching. Problematizar os processos reflexivos desses profissionais permite diferenciar qualitativa e eticamente suas atuações, possibilitando o fomento multiprofissional no esporte.(AU)

The aim of this study consists in phenomenologically identifying and understanding, by the report of Sport Psychologists (SP) and coaches, in their practical experience, how would be the reflexive processes that take place in their performance, as learned from reports of their experiences. The research method chosen was phenomenology, since it offers the necessary resources for such a dive along with the reflective experience. The intentional sample was outlined by SP and coaches (Physical Education professionals who use coaching) active in high performance sports, who have or are working in collective and/or individual sports. Nine interviews were conducted (five with SP, four with coaches). Access to the object of this study took place by in-depth and semi-structured interviews, guided by suspensive listening. The triggering questions were formulated based on the adapted Structured Reflection Procedure. For the analysis of the interviews, a synthesis of each report was carried out, followed by the intentional crossing. As results, it was noticed that SP and coaches bring some similarities regarding the ways of reflecting on their practice. However, their experiences of these reflective processes are that they can take different directions. The SP are based on the regulation of the profession and guard themselves in their notes, bringing their experiences and reflections on the processes experienced. Coaches bring in their explanations a coherent, organized, and compatible work with the coaching method. Problematizing the reflective processes of these professionals allows to differentiate their actuation qualitatively and ethically, making the multiprofessional phenomenon in sport possible.(AU)

El objetivo de este estudio consiste en identificar y comprender fenomenológicamente, a partir de la experiencia práctica de psicólogos del deporte (PD) y coaches, cómo serían los procesos reflexivos que se llevan a cabo en su rendimiento, tal y como se desprende de los informes de experiencias. El método de investigación elegido fue la fenomenología, ya que ofrece los recursos necesarios junto con la experiencia. La muestra intencional fue delineada por PD y coaches (profesionales de la educación física que utilizan el coaching) activos en deportes de alto rendimiento, que tienen o están trabajando en deportes colectivos e/o individuales. Se realizaron nueve entrevistas (cinco con PD, cuatro con coaches). El acceso al objeto de este estudio fue entrevistas en profundidad y semiestructuradas, guiadas por escuchas suspensivas. Las preguntas se formularon desde el procedimiento de reflexión estructurado adaptado. Para el análisis de las entrevistas, se hizo una síntesis de cada informe, seguida del cruce intencional. Como resultados, se notó que los PD y coaches tienen algunas similitudes con respecto a las formas de reflexionar sobre su práctica. Sin embargo, las experiencias que hacen de estos procesos pueden tomar diferentes direcciones. Los(las) PD se basan en la regulación de la profesión y se protegen en sus notas, aportando sus experiencias y reflexiones sobre los procesos vividos. Los(las) coaches plantean en sus explicaciones un trabajo coherente, organizado y compatible con el método de Coaching. Problematizar los procesos reflexivos de estos profesionales permite diferenciar sus acciones de manera cualitativa y ética, además de posibilitar la promoción multiprofesional en el deporte.(AU)

A disciplina psicologia do esporte nos cursos de psicologia e educação física / Sports psychology in psychology and physical education courses / La materia psicología del deporte en los cursos de psicología y educación física

Este discute a representatividade da disciplina Psicologia do Esporte nos cursos de Psicologia e Educação Física em instituições de ensino superior reconhecidas pelo MEC e situadas na região Sul do país. Foi realizado um estudo documental, com base nos currículos das Instituições. Os resultados revelaram que no Sul do Brasil 21,02% dos cursos de Psicologia, 41,96% dos cursos de bacharelado em Educação Física e apenas 14,83% dos cursos de licenciatura em Educação Física apresentam a disciplina Psicologia do Esporte em sua grade curricular. Observou-se que a disciplina é ofertada mais frequentemente em regime obrigatório nos cursos de bacharelado em Educação Física. Nos cursos de Psicologia, quando ofertada, costuma ser optativa. Os resultados evidenciam uma maior oferta da disciplina para os estudantes de Educação Física, em relação aos de Psicologia, o que pode estar relacionado ao próprio contexto de surgimento da disciplina e sua popularização no meio acadêmico. Para que esse panorama possa mudar e se possa oferecer uma formação adequada no curso de Psicologia para fomentar essa opção de carreira, há necessidade de se repensar o currículo e o próprio perfil do egresso, de forma a dar mais oportunidade aos estudantes para que conheçam as bases teóricas e os campos de aplicação da Psicologia do Esporte. Tal lacuna pode acarretar a fragilização da disseminação desse conhecimento aos estudantes de graduação e a consequente ocupação do mercado de trabalho.(AU)

This study discusses the representativeness of Sports Psychology in Psychology and Physical Education courses at higher education institutions from Southern Brazil. A documentary study was conducted based on the institutions' curricula. Results show that 21.02% of the Psychology major, 41.96% of the bachelor's in Physical Education, and only 14.83% of the license in Physical Education offer Sports Psychology in their curricula. Sports Psychology is most often offered as a compulsory subject in the bachelor's program in Physical Education, whereas Psychology courses offer it mainly as an elective. Physical Education students have greater contact with the discipline when compared with Psychology students, which may be explained by its context of development and popularization in the academic environment. To change this scenario and offer adequate education in the Psychology programs to foster this career option, institutions must rethink their curriculum and the graduate profile itself. This would give students better opportunity to get to know its theoretical bases and fields of application. Such a gap can hinder the dissemination of this knowledge to undergraduate students and the consequent labor market occupation.(AU)

El objetivo de este estudio es discutir la representatividad de la materia Psicología del Deporte en los cursos de Psicología y Educación Física en instituciones de educación superior de la región Sur de Brasil, reconocidas por el Ministerio de Educación (MEC). Se realizó un estudio documental, basado en los planes de estudio de las instituciones. Los resultados revelaron que, en el Sur de Brasil, el 21,02% de los cursos de Psicología, el 41,96% de los cursos de licenciatura en Educación Física y sólo el 14,83% de los cursos de profesorado en Educación tienen la materia Psicología del Deporte en sus planes de estudio. Se observó que la materia Psicología del Deporte se ofrece con mayor frecuencia como asignatura obligatoria en los cursos de licenciatura en Educación Física. Cuando se ofrece en los cursos de Psicología, es una materia optativa. Los resultados muestran una mayor oferta para los estudiantes de Educación Física en comparación con Psicología, lo que puede estar relacionado con el contexto del surgimiento de la Psicología del Deporte como materia y su popularización en el ámbito académico. Para que este escenario cambie y sea posible ofrecer una formación adecuada en el curso de Psicología con el fin de fomentar esta opción de carrera, es necesario repensar el plan de estudios y el perfil del egresado, así los estudiantes tendrán más oportunidades de conocer sus bases teóricas y sus campos de actuación. Tal brecha puede debilitar la difusión de este conocimiento a los estudiantes de grado y la consecuente ocupación en el mercado laboral.(AU)

The state mindfulness scale for physical activity: further psychometrics properties / Escala de estado de mindfulness para atividade física: novas propriedades psicométricas / Escala de mindfulness en la actividad física: nuevas propiedades psicométricas

Mindfulness has been defined as attention and awareness to the present with an attitude of openness, non-judgment, and acceptance. It is suggested that mindfulness can positively influence experiences in sports and physical activity, increasing adherence to these activities. This study aimed to examine new psychometric properties of the State Mindfulness Scale for Physical Activity (SMS-PA) using classical and modern testing theories among Brazilian sport and exercise practitioners. Two studies were conducted. In the first, with 617 Brazilian sports practitioners, confirmatory factor analysis supported the bifactor structure of the SMS-PA composed of two specific (mental and body mindfulness) and one general factor (state mindfulness), which did not vary among genders. The Rasch Rating Scale Model (RSM) supported essential one-dimensionality indicated by the general factor with good item fit statistics (infit/outfit 0.62-1.27). The model presented a good level of Rasch reliability (0.85), and the items difficulty estimation provided an understanding of the continuum represented by their content. In the second study, with 249 Brazilian exercise practitioners, the structural equation modeling showed that Body Mindfulness was associated with positive outcomes (positive affect and satisfaction with practice). The mediation analysis showed that people with higher levels of Body mindfulness tend to experience greater levels of Positive Affect and, consequently, greater Satisfaction with exercises. The results suggest that the Brazilian version of the SMS-PA is an appropriate measure of the state of mindfulness.(AU)

Mindfulness pode ser definido como atenção e consciência no momento presente com uma atitude de abertura, não julgamento e aceitação. A literatura sugere que o mindfulness pode influenciar positivamente experiências no esporte e atividade física e pode exercer um papel na adesão a essas atividades. Este estudo teve como objetivo investigar novas propriedades psicométricas da State Mindulness Sacale for Physical Activity (SMS-PA) utilizando as teorias clássicas e modernas dos testes em praticantes de exercício físico e esporte brasileiros. Dois estudos foram conduzidos. No primeiro, com 617 brasileiros praticantes de esporte, a Análise Fatorial Confirmatória (AFC) demonstrou adequação à estrutura bifatorial da SMS-PA composta por dois fatores específicos (mindfulness mental e físico) e um fator geral (estado de mindfulness), que apresentou invariância entre sexos. A Rasch Rating Scale Model (RSM) corroborou a unidimensionalidade essencial indicada pelo fator geral com bons índices de ajustes (infit/outfit 0.62 -1.27). O modelo apresentou bom nível de precisão Rasch (.85), e a estimação de dificuldade dos itens possibilitou compreensão do continuum representado pelo conteúdo dos itens. No segundo estudo, com 249 brasileiros praticantes de esporte, a Modelagem de Equações Estruturais demonstrou que o mindfulness físico esteve associado a afetos positivos e satisfação com a prática. A análise de mediação mostrou que pessoas com níveis altos de mindfulness físico tendem a apresentar níveis mais elevados de afeto positivo e, consequentemente, níveis mais elevados de satisfação com a prática. Os resultados sugerem que a versão brasileira do SMS-PA é uma medida apropriada do estado de mindfulness para atividades físicas.(AU)

La atención plena puede definirse como la atención y la conciencia en el momento presente con una actitud de apertura, no juicio y aceptación. La literatura sugiere que el mindfulness puede influir positivamente en las experiencias en el deporte y en la actividad física, además de desempeñar un papel en la adherencia a estas actividades. Este estudio tuvo como objetivo investigar nuevas propiedades psicométricas de la State Mindfulness Scale for Physical Activity (SMS-PA) utilizando las teorías clásicas y modernas de las pruebas en practicantes de ejercicio físico y de deporte en Brasil. Para ello, se realizaron dos estudios. En el primer, participaron 617 practicantes de deporte brasileños, y el análisis factorial confirmatorio (AFC) demostró adecuación en la estructura bifactorial de la SMS-PA, compuesta por dos factores específicos (mindfulness mental y físico) y un factor general (estado de mindfulness), que mostró invarianza entre sexos. El Rasch Rating Scale Model (RSM) corroboró la unidimensionalidad esencial indicada por el factor general con buenos índices de ajuste (infit/outfit 0,62-1,27). El modelo mostró un buen nivel de precisión de Rasch (.85), y la estimación de la dificultad de los ítems permitió comprender el continuo representado por el contenido de estos. En el segundo estudio, con 249 practicantes de deporte, el modelo de ecuaciones estructurales mostró que el mindfulness físico estaba asociado a resultados positivos (afecto positivo y satisfacción con la práctica). El análisis de mediación reveló que las personas con altos niveles de mindfulness físico tendían a tener mayores niveles de afecto positivo y, en consecuencia, mayores niveles de satisfacción con la práctica. Los resultados sugieren que la versión brasileña de la SMS-PA es una medida adecuada de mindfulness.(AU)

Thermal and behavioral response of horses submitted to functional exercises and acupuncture / Resposta térmica e comportamental de equinos submetidos a exercícios funcionais e acupuntura

The present research evaluated muscle activation degrees and relaxation of patrolling horses submitted to dynamic mobilization exercises, associated or not with acupuncture. Twelve mixed breed gelding, aged 10 ± 2.0 years, were distributed in three treatments. Treatment with a single session of dynamic mobilization exercises (longitudinal cervical flexion of head between hooves, between carpus and to up to chest); treatment with a single acupuncture session during 20 minutes, and treatment with a single session of dynamic mobilization exercises with acupuncture. Thermographic images were analyzed before and after applying treatments to the cervical, thoracic, dorsal, abdominal and pelvic regions. Animal behavior was assessed through five minutes filming, before and ten minutes after the end of each treatment application, in an uninterrupted way. Increase in animals body temperature at the end of the single session of functional exercises (P < 0.0001) at all animal regions were reported, being cervical and thoracic areas with highest final temperature values. There was no temperature variation for other treatments (P > 0.05). All treatments stimulated higher expression frequency (P < 0.05) of relaxation behaviors. A single dynamic mobilization exercises session is enough to promote intense muscular response in entire horse body; and with acupuncture, individually or associated, promoted muscle and mental relaxation, interfering positively in animal welfare.

Objetivou-se avaliar o grau de ativação e relaxamento muscular de equinos de patrulhamento submetidos à exercícios de mobilização dinâmica associados ou não à acupuntura. Doze cavalos castrados, sem raça definida, com idade de 10 ± 2,0 anos, foram distribuídos em três tratamentos: tratamento com uma sessão única de exercícios de mobilização dinâmica (flexão cervical longitudinal da cabeça entre os cascos, entre os carpos e até o peito); tratamento com sessão única de acupuntura (20 minutos); e tratamento com sessão única composta por exercícios de mobilização dinâmica associados a acupuntura. Foram analisadas imagens termográficas antes e após a aplicação dos tratamentos das regiões cervical, torácica, dorsal, abdominal e pélvica. A avaliação comportamental foi obtida por meio de filmagens 5 minutos antes e 10 minutos após o término da aplicação dos tratamentos, de maneira ininterrupta. Houve aumento (P < 0,0001) na temperatura corporal dos animais ao final da sessão única de exercícios funcionais para todas as regiões estudadas, sendo a cervical e torácica aquelas com maior valor de temperatura final. Não houve variação da temperatura nos demais tratamentos (P > 0,05). Todos os tratamentos geraram maior frequência (P < 0,05) na expressão de comportamentos relacionados ao relaxamento. A realização de uma sessão única de exercícios de mobilização dinâmica é suficiente para promover uma intensa resposta muscular em todo o corpo do equino, e tanto os exercícios funcionais quanto a acupuntura, de maneira individual ou associada, foram capazes de promover relaxamento muscular e mental, interferindo de maneira positiva no bem-estar dos animais.

Oxigenación apnéica para extracción de cuerpo extraño en vía aérea / Apneic oxygenation for extracting a foreign body in the airway

La oxigenación apnéica consiste en la administración de flujos altos de oxígeno a través de algún dispositivo supraglótico mientras el paciente se mantiene en apnea. Se explica por qué el alveolo desnitrogenizado con una composición en su mayor parte de oxígeno, permite la difusión alveolo capilar y genera una presión subatmosférica capaz de arrastrar el flujo de oxigeno existente en el árbol traqueobronquial hasta el mismo alveolo, siempre y cuando no hubiera obstrucción mecánica de la vía aérea. El tiempo aumenta considerablemente hasta que la saturación de oxígeno disminuya, lo que se conoce como tiempo de apnea segura. Se presenta la experiencia de emplear esta técnica en un escolar de 5 años sin antecedentes patológicos, que ingirió un cuerpo extraño (semilla de girasol), la cual se localizaba en vía aérea bronquio principal derecho. Este se extrajo por fibrobroncoscopía bajo anestesia total intravenosa, priorizando la ventilación espontánea hasta localizarlo, y luego, debido a la dificultad que presentó su extracción, se empleó relajación muscular y apnea para optimizar las condiciones de la extracción. Durante este periodo, se empleó la técnica de oxigenación apnéica, la cual se mantuvo durante 12 min. La saturación pulsátil de oxigeno fue mayor al 92 por ciento, tiempo suficiente para culminar la extracción con éxito y sin complicaciones(AU)

Apneic oxygenation consists in the administration of high flows of oxygen through a supraglottic device while the patient remains in apnea. It is explained because the alveolus with low nitrogen concertation/accumulation, with a composition mostly of oxygen, allows capillary alveolus to diffuse, as well as it generates a subatmospheric pressure capable of dragging the oxygen flow existing in the tracheobronchial tree to the alveolus itself, as long as there is no mechanical airway obstruction. The time increases considerably until oxygen saturation decreases, which is known as the safe apnea time. The experience of using this technique is presented is it was used with a five-year-old boy with no pathological history and who swallowed a foreign body (sunflower seed), which was located in the airway, specifically the right main bronchus. The foreign body was extracted by fiberoptic bronchoscopy under total intravenous anesthesia, prioritizing spontaneous ventilation until it was located; and then, due to the difficulty for its extraction, muscle relaxation and apnea were used to optimize the extraction conditions. During this period, the apneic oxygenation technique was used and maintained for twelve minutes. Pulsatile oxygen saturation was greater than 92 percent, enough time to complete the extraction successfully and without complications(AU)

Evaluación de la relajación neuromuscular y predictores de vía aérea difícil en pacientes programados para cirugía general Hospital Central Universitario Dr. Antonio María Pineda / Evaluation of muscle relaxation and predictors of difficult airway in patients programmed for general surgery Hospital Central Universitario Dr. Antonio María Pineda

Se realizó una investigación experimental tipo ensayo clínico controlado simple ciego con el fin de evaluar la relajación muscular y los predictores de vía aérea difícil en pacientes programados para cirugía general en el Hospital Central Universitario Dr. Antonio María Pineda. La muestra estuvo conformada por 100 pacientes distribuidos aleatoriamente en cuatro grupos de 25 pacientes cada uno. En los grupos Experimental-1 (E-1) y Control-1 (C-1) se utilizó una dosis del bloqueante neuromuscular Bromuro de Rocuronio de 0,6 mg/kg y en los grupos Experimental-2 (E-2) y Control-2 (C-2) de 1 mg/kg. La edad promedio de los pacientes fue de 34,8 ± 9,8 años; en los grupos E-1 y E-2, los predictores de vía aérea difícil predominantes fueron distancia esternomentoniana (32% y 42%), distancia tiromentoniana (24% y 40%), distancia interincisivos clase I (88% y 92 %), circunferencia de cuello  40 cm (16% y 8 %), Mallampati (88% y 40%), extensión atlanto-occipital (28% y 20%) y protrusión mandibular (28% y 20%). En el 72% y 80% de los pacientes de los grupos experimentales y control no hubo intento adicional de intubación orotraqueal (IOT); el tiempo invertido para alcanzar la IOT fue < 1 minuto en el grupo C-2 (64%) y E-2 (72%). Existen diferencias estadísticamente significativas entre el número de intentos para alcanzar la IOT, la presencia de predictores de vía aérea difícil y la dosis de bloqueante neuromuscular utilizada lo que evidencia de que a medida que se aumenta la dosis del medicamento hay mayor posibilidad de éxitos en la IOT, aun cuando estén presentes predictores de vía aérea difícil(AU)

An experimental simple blind controlled clinical trial was carried out to evaluate muscle relaxation and predictors of difficult airway in patients scheduled for general surgery at the Hospital Central Universitario Dr. Antonio María Pineda. The sample consisted of 100 patients randomly distributed into four groups of 25 patients each. Patients from the Experimental-1 (E-1) and Control-1 (C-1) groups received 0.6 mg/kg of the neuromuscular blocking agent Rocuronium Bromide while Experimetal-2 (E-2) and Control-2 (C-2) patients received a dosage of 1 mg/kg. Average age of participants was 34.8 ± 9.8 years. Predictors of difficult airway in E-1 and E-2 were sternomental distance (32% and 42%, thyromental distance (24% and 40%), interincisive distance class 1 (88% and 92%), neck circumference  40 cm (16% and 8%), Mallampati (88% and 40%), atlanto-occipital extension (28% and 20%) and mandibular protrusion (28% and 20%). In 72% and 80% of patients from the E and C groups there was not an additional attempt of orotracheal intubation (OTI); the time invested to reach the OTI was less than one minute in 64% of patients from the C-2 and 72% of the E-2. There are statistically significant differences between the number of attempts to reach the OTI, presence of predictors of difficult airway and the dose of Rocuronium Bromide which means that as the drug dosage increases, there is a greater possibility of success in the OTI, even when predictors of difficult airway are present(AU)

Ameloplastia positiva en relación céntrica como método auxiliar durante la finalización en el tratamiento de ortodoncia en un paciente bruxista / Positive ameloplasty in centric relationship as an auxiliary method during finalization in the orthodontic treatment in a bruxist patient

A continuación se presenta un caso de un paciente de 12 años de edad, con antecedente de bruxismo, con biotipo mesofacial, tercio inferior dolicofacial, hipertonicidad muscular en maseteros, cierre labial forzado con incompetencia labial de 4 milímetros con dolor en sinoviales anteriores inferiores. Los objetivos de tratamiento consistieron en lograr relajación muscular y promover un posicionamiento condilar ortopédicamente funcional y estable, realizar control vertical para disminuir gap interlabial, alinear líneas medias, mantener clase I molar bilateral, clase I canina bilateral y clase I incisiva, crear overjet y overbite adecuados, con recuperación estética y función del segmento anterior. Debido a eventos adversos durante la etapa de cierre de espacios, la clase molar y canina I no se logró, pero se aseguró mediante ameloplastias positivas la función y estética adecuadas para tener un tratamiento de ortodoncia estable a largo plazo (AU)

The following is a case of a 12-year-old patient, with a history of bruxism, with a mesofacial biotype, lower third of the facial area, muscular hypertonicity in the masseters, a forced labial closure with a 4-millimeter labial incompetence with pain in inferior anterior synoviums. Treatment objectives consisted of achieving muscle relaxation and promoting orthopedically functional and stable condylar positioning, perform vertical control to decrease interlabial gap, align midlines, maintain bilateral molar class I, bilateral canine class I and incisive class I, create adequate overjet and overbite, with aesthetic recovery and function of the anterior segment. Due to adverse events during the closing phase of spaces, the molar and canine I class was not achieved, but positive function and aesthetics were ensured by positive ameloplasties in order to have a long-term stable orthodontic treatment (AU)

La rigidez cadavérica, el espasmo cadavérico y tipos de fibras musculares / The cadaveric rigidity, the cadaveric spasm and types of muscle fibers

La rigidez cadavérica (rigor mortis) es un proceso no muy bien comprendido por la mayoría de los médicos. El conocimiento de la intimidad del proceso de la rigidez cadavérica es de vital importancia ya que es una de las variables que junto con las livideces (livor mortis) y la temperatura (algor mortis) del cadáver ayudan a determinar el cronotanatodiagnóstico, tanatocronodiagnóstico o intervalo postmortal del período inmediato de la muerte. Para entender el mecanismo de la rigidez y el espasmo cadavérico es preciso hacer un repaso de la contracción muscular fisiológica en el vivo. Hay que tener presente que el tipo de fibra muscular predominante modificará las características de la contracción muscular fisiológica en el vivo, y también la rigidez y el espasmo cadavérico. (AU)

The cadaveric rigidity (rigor mortis) is a process which is not very well understood by the majority of the doctors. The knowledge of the intimacy of the cadaveric stiffness process is of vital importance since it is one of the variables that, as well as the postmortem lividity (livor mortis) and the body temperature post mortem (algor mortis) help determine the chronotanatodiagnostic, tanatochronodiagnostic or postmortal interval of the immediate period of death. In order to understand the mechanism of stiffness and cadaveric spasm, it is necessary to review the physiological muscle contraction in vivo. We should keep in mind that the predominant type of muscle fiber will modify the characteristics of physiological muscle contraction in vivo, as well as stiffness and cadaveric spasm. (AU)

Efficacy of the complementary therapies in the management of cancer pain in palliative care: A systematic review / Eficácia das terapias complementares no manejo da dor oncológica em cuidados paliativos: revisão sistemática / Eficacia de las terapias complementarias en el manejo del dolor oncológico en los cuidados paliativos: revisión sistemática

Objective: to synthesize the knowledge and to critically evaluate the evidences arising from randomized controlled trials on the efficacy of the complementary therapies in the management of cancer pain in adult patients with cancer in palliative care. Method: a systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The search for articles in the MEDLINE, ISI Web of Knowledge, CENTRAL Cochrane, and PsycINFO databases, as well as the manual search, selection of studies, data extraction, and methodological assessment using the Cochrane Bias Risk tool were performed independently by two reviewers. Results: eight hundred and fifteen (815) studies were identified, six of them being selected and analyzed, of which three used massage therapy, one study used a combination of progressive muscle relaxation and guided imaging, and another two studies used acupuncture. Most of the studies had an uncertain risk of bias (n=4; 67%). Conclusion: while the evidence from the studies evaluating the use of massage therapy or the use of progressive muscle relaxation and guided imaging for the management of cancer pain in these patients demonstrated significant benefits, the other two studies that evaluated the use of acupuncture as a complementary therapy showed contradictory results, therefore, needing more research studies to elucidate such findings.

Evaluation of relaxant responses properties of cinnamon essential oil and its major component, cinnamaldehyde on human and rat corpus cavernosum

ABSTRACT Cinnamomum cassia (Cinnamon) is a well-known traditional medicine with therapeutic benefits for centuries. We evaluated the effects of cinnamon essential oil (CEO) and its main component cinnamaldehyde (CA) on human corpus cavernosum (HCC) and rat CC. The essential oil of cinnamon was analyzed for the confirmation of the oil profile. HCC specimens from patients undergoing penile prosthesis surgery (age 48-69 years) were utilized for functional studies. In addition, erectile responses in anesthetized control and diabetic rats were evaluated in vivo after intracavernosal injection of CEO and CA, and rat CC strips were placed in organ baths. After precontraction with phenylephrine (10µM), relaxant responses to CEO and CA were investigated. CA (96.9%) was found as the major component. The maximum relaxation responses to CEO and CA were 96.4±3.5% and 96.0±5.0% in HCC and 97.5±5.5% and 96.8±4.8% in rat CC, respectively. There was no difference between control and diabetic rats in relaxation responses to CEO and CA. The relaxant responses obtained with essential oil and CA were not attenuated in the presence of nitric oxide synthase (NOS) inhibitor, and soluble guanylate cyclase inhibitor (sGS) in CC. In vivo, erectile responses in diabetic rats were lower than in control rats, which was restored after intracavernosal injection of CEO and CA. CEO and CA improved erectile function and relaxation of isolated strips of rat CC and HCC by a NO/cGMP-independent mechanism. Further investigations are warranted to fully elucidate the restorative effects of CEO and CA on diabetic erectile dysfunction.

Evaluation of smooth muscle relaxant potential of Bismarckia nobilis (Hildebr. & Wendl.) in diarrhea, hypertension and asthma by ex-vivo and in-vivo method / Evaluación del potencial relajante en músculo liso de Bismarckia nobilis (Hildebr. & Wendl.) en diarrea, hipertensión y asma por métodos ex vivo e in vivo

To explore the mechanistic basis behind smooth muscle relaxant prospective of Bismarckia nobilis in gastrointestinal, respiratory and cardiovascular ailments. The methanolic extract of B. nobilis and sub-fractions have been evaluated in vitro rabbit isolated tissues, in vivo castor oil-induced diarrhea in rats and charcoal meal activity in mice. The B. nobilis extract relaxed spontaneous and K+(80 mM)- induced contractions in rabbit isolated jejunum preparations, CCh (1 µM) and K+ (80 mM)-induced contractions in tracheal and bladder preparations, PE (1 µM) and K+ (80 mM)-induced concentrations in aorta preparations, likewise verapamil. Spasmolytic activity of dichloromethane fraction is stronger as compared to aqueous fraction. In vivo castor oil-induced diarrhea in rats and charcoal meal activity in mice further supported spasmolytic activity. B. nobilis extract possess anti-spasmodic, anti-diarrheal, airway relaxant and vasodilator activities possible mediated through calcium channel blocking mechanism, justifying therapeutic utility of B. nobilis in diarrhea, asthma and hypertension.

El objetivo de trabajo fue explorar el mecanismo de acción relacionado con el efecto relajante del músculo liso inducido por Bismarckia nobilis (B. nobilis) en enfermedades gastrointestinales, respiratorias y cardiovasculares. El extracto metanólico de B. nobilis y subfracciones fue evaluado in vitro en tejidos aislados de conejos. Además se evaluó diarrea in vivo inducida con aceite de ricino en ratas y la actividad de harina de carbón vegetal en ratones. El extracto de B. nobilis relajó tanto las contracciones espontáneas como las inducidas por K+(80 mM) en preparaciones de yeyuno aisladas de conejos, las contracciones inducidas por PE (1 µM) y K+(80 mM) inducidas en preparaciones de aorta; de manera similar a verapamilo. La actividad espasmolítica de la fracción de diclorometano es más potente en comparación con la fracción acuosa. La diarrea inducida in vivo por el aceite de ricino en ratas y la actividad de la harina de carbón vegetal en ratones apoyaron aún más la actividad espasmolítica. El extracto de B. nobilis posee actividades antiespasmódicas, antidiarreicas, relajantes de las vías respiratorias y vasodilatadoras, posibles a través del mecanismo de bloqueo de los canales de calcio, lo que justifica la utilidad terapéutica de B. nobilis en la diarrea, el asma y la hipertensión.

Rapid Functional Enhancement of Ankylosing Spondylitis with Severe Hip Joint Arthritis and Muscle Strain

Arthritis of hip joints deteriorates the quality of life in ankylosing spondylitis (AS) patients. Secondary to the articular inflammatory process, the shortened hip-girdle muscles contribute to the decreased joint mobility which may lead to the functional impairment. As the limitation of range of motion (ROM) usually progress slowly, clinicians regard it as a chronic condition and prescribe long-term therapy. However, by short-term intensive multimodal treatment, a 20-year-old man diagnosed as AS with severely limited hip joint ROM who relied on crutches doubled the joint angle and could walk independently only within 2 weeks. The combination included intra-articular steroid injection, electrical twitch obtaining intramuscular stimulation, extracorporeal shock wave therapy, heat, manual therapy, and stretching exercises. The management focused on the relaxation of hip-girdle muscles as well as the direct control of intra-articular inflammation. Hereby, we emphasize the effectiveness of intensive multimodal treatment in improving the function even within a short period.

Comparison of Sit and Reach Test, Straight Leg Raise Test and Visual Analogue Scale When Applying Static Stretching and Mulligan's Two Leg Rotation in Young Adults with Hamstring Shortness

PURPOSE: This study compared the effects of Static stretching and Mulligan's Two-leg rotation about the Hamstring flexibility, Hip range of motion, and pain.METHODS: The subjects were allocated randomly into two groups: Static stretching group (n=13) and Mulligan's two leg rotation group (n=14). The study was designed with stretching protocols for four minutes and thirty seconds per day five times a week for three weeks in total. Measurements, including the Sit and reach test, Active/Passive Straight leg raise, and Visual analogue scale, were conducted before and after the intervention. The data were analyzed using a paired t-test and independent t-test.RESULTS: The flexibility of the two leg rotation group was higher than the static stretching group after the intervention. The post-sit and reach test value of the two leg rotation group was significantly higher than the pre-sit and reach test value of the static stretching group. In addition, the variance of the sit and reach test of the two leg rotation group was significantly higher than that of the static stretching group.CONCLUSION: These results showed that two leg rotation techniques have a positive effect on the changes in the sit and reach test and active straight leg raise test. Two leg rotation techniques can be recommended as a self-stretching and easier way to stabilize the lumbopelvic rhythm, reduce the stiffness of the muscle and relieve pain. This is effective in preventing muscle damage, enabling muscle relaxation and reducing the risk of injury to the spine during daily lives and in sports activities.

Advances in chemical constituents of isoquinoline alkaloids from Nelumbo nucifera and their smooth muscle relaxation effect / 中国中药杂志

Lotus( Nelumbo nucifera) is a traditional medicinal plant,and nowadays it is regarded both as medicine and food. It is widespread across China and rich in natural resources. Almost every part of N. nucifera could be used for medical or edible purpose,including seeds( Lianzi),black ripe fruits( Shilianzi),seed coats( Lianyi),green embryos of mature seed( Lianzixin),flowers( Lianhua),stamens( Lianxu),receptacles( Lianfang),leaves( Heye),leaf or flower stalks( Hegeng),leaf bases( Heyedi),rhizomes( Ou) and rhizome nodes( Oujie). Therefore,this plant is praised as a commercial crop with great economic values. Isoquinoline type alkaloids are the main chemical components of lotus. Smooth muscles usually exist in the digestive tract,respiratory tract and vascular,urinary,reproductive and other human systems. Dysfunction of smooth muscle contraction will induce many diseases including hypertension,asthma and gastrointestinal disorder,etc.,and most of current therapeutic strategies rely on relaxation of smooth muscle by drugs.Previous studies have shown that alkaloids of lotus have strong relaxation activity on smooth muscle. The present paper reviews phytochemistry and smooth muscle relaxation activity of 59 isoquinoline alkaloids from N. nucifera through accessing CNKI,PubMed and multiple databases for biomedical sciences.

Sugammadex associated profound bradycardia and sustained hypotension in patient with the slow recovery of neuromuscular blockade: A case report

BACKGROUND: New complications associated with sugammadex have been increased since its widespread use. We report a case of an 80-year-old male who experienced profound bradycardia and sustained hypotension after administration of sugammadex. CASE: Following administration of 200 mg sugammadex after laparoscopic cholecystectomy, sudden bradycardia (29 beats/min) developed for 10 seconds and his train-of-four (TOF) ratio remained at 0.2 for 5 min. An additional 200 mg sugammadex was administered and profound bradycardia (21–30 beats/min) and hypotension (60/40 mmHg) developed. Atropine at 0.5 mg was administered, but the effect lasted only 30 s. Profound bradycardia occurred four more times at 30 s intervals, and ephedrine and phenylephrine were injected intermittently to increase the patient's heart rate and blood pressure. The TOF ratio became 0.9 about 10 min after administration of additional sugammadex. CONCLUSIONS: Awareness must be heightened regarding the possibility of sugammadexinduced bradycardia and hypotension, and more attention should be paid to patients with slow recovery times following muscle relaxation, despite the use of sugammadex.

Relaxant effects of Peperomia hispidula (Sw.) A. Dietr. on isolated rat tracheal rings / Efecto relajante de Peperomia hispidula (Sw.) A. Dietr. sobre anillos aislados de tráquea de rata

Peperomia hispidula (Sw.) A. Dietr. is used in Mexican traditional medicine for treating respiratory illnesses such as asthma. The latter disorder results from an excessive and inappropriate constriction of airway smooth muscle. The aim of the present study was to evaluate the relaxant activity of P. hispidula on isolated rat tracheal rings contracted with carbachol. The methyleugenol was identified as the main active constituent in the dichloromethane extract. To explore the possible mechanism of action, concentration-response curves were constructed in the presence and absence of propranolol (3 µM), indomethacin (10 µM), glibenclamide (1 µM), and L-NAME (300 µM), finding that neither reduced methyleugenol-induced smooth muscle relaxation. In conclusion, P. hispidula herein displayed relaxant activity on rat tracheal rings. The effect of methyleugenol, was probably not related to the activation of ß2-adrenoceptors, prostaglandins, K+ATP channels or nitric oxide.

Peperomia hispidula (Sw.) A. Dietr. es utilizada en la medicina tradicional mexicana para tratar enfermedades respiratorias como el asma. Este último trastorno es el resultado de una contracción excesiva e inapropiada del músculo liso de las vías respiratorias. El objetivo del presente estudio fue evaluar la actividad relajante de P. hispidula sobre anillos aislados de tráquea de rata contraídos con carbacol. El metileugenol fue identificado como el principal constituyente activo en el extracto de diclorometano. Para explorar el posible mecanismo de acción, se construyeron curvas concentración-respuesta en presencia y ausencia de propranolol (3 µM), indometacina (10 µM), glibenclamida (1 µM), y L-NAME (300 µM), encontrando que ninguno redujo la relajación del músculo liso inducida por metileugenol. En conclusión, P. hispidula muestra actividad relajante en anillos de tráquea de rata. El efecto de metileugenol, al parecer no está implicado con la activación de los receptores ß2-adrenérgicos, prostaglandinas, canales de K+ATP u óxido nítrico.

Relajación muscular y depresión en pacientes con esclerosis múltiple: estudio de caso múltiple / Muscular relaxation and depression among patients diagnosed with multiple sclerosis: a multiple-case study

El objetivo de esta investigación fue medir el efecto del Entrenamiento en Relajamiento Muscular Progresivo de Edmund Jacobson en los niveles de Depresión de tres pacientes con Esclerosis Múltiple (EM). Participaron inicialmente y de forma voluntaria 8 sujetos, todos del género femenino, de clase media, quienes no contaban con ningún tipo prestaciones en salud. De dichos casos valorados, se eligieron a tres pacientes con diferentes niveles de depresión: primer caso (sin depresión), segundo caso (depresión leve) y tercer caso (depresión moderada). Ya que sólo se encontraron estos niveles de depresión en el grupo valorado, es decir no se encontró depresión grave, lo anterior de acuerdo con los resultados arrojados por el Inventario de Depresión de Beck. El trabajo se basa en un diseño de estudio de caso múltiple, donde cada caso debe ser tratado en forma individual para luego sacar conclusiones del cruce de dichos casos. Con resultados alentadores, ya que en las tres situaciones hubo mejoras, demostrando que dicho entrenamiento de relajación muscular tiene efectos positivos sobre los niveles de ansiedad de este tipo de pacientes. Además, en cuanto al análisis introspectivo de cada paciente reportaron mejoras no sólo en depresión, sino, en autoestima, comunicación, socialización, aprendizaje y aceptación de la enfermedad.

The purpose of this research was to measure what the effect of a Progressive Muscular Relaxation Training of Edmund Jacobson (Year) would have on the different depression levels of 3 multiple sclerosis (MS) patients. Participants included 8 middle-class females, who did not have any type of health care. From those 8 participants, only 3 were selected that showed a different level of depression: first participant (No depression), second participant (low depression), and third participant (moderate depression). Since only these types of different levels of depression were found among the participants, severe depression was not found, though according to Beck's Depression Questionnaire (Year). This is a multiple-case study type of research, where each participant was treated individually, to better understand in an in depth manner the connection of these cases. We can say that our results are promising, since all three participants showed improvements, indicating a positive effect with the Progressive Muscular Relaxation Training over anxiety levels of participants. As well, according to an introspective analysis of each participant were shown improvements not only in depression levels but in self-esteem, socialization, communication skills, learning and adaptability to their disease.
