ABSTRACT

ABSTRACT Introduction: The emergence of orthodontic aligners has provided an aesthetic and comfortable option for orthodontic treatment. However, the encapsulated design of the aligners can influence the masticatory muscles, and might compromise safe treatment. Objective: This preliminary longitudinal study aimed to investigate whether the use of orthodontic aligners affects the biting force and myoelectric activity of the superficial masseter and anterior temporal muscles. Methods: Ten subjects participated in the study and underwent treatment during an 8-month follow-up period. The root mean square (RMS), the median power frequency (MPF) of the surface electromyography (sEMG) signals, and the biting force (kgf) were recorded and normalized relative to the pretreatment condition. The data were analyzed by repeated-measure analysis of variance (ANOVA), with the significance level set at 5%. Results: Both the superficial masseter and the anterior temporal muscles presented an increase in sEMG signal activity during the treatment, with a marked increase in the latter compared to the former (p<0.05). Moreover, a significant decrease in bite force was evidenced (p<0.05). Conclusions: This preliminary study observed that the orthodontic aligners affected the muscle recruitment pattern of masticatory muscles, and reduced biting performance during the 8-month follow-up period.


RESUMO Introdução: O surgimento dos alinhadores ortodônticos tem proporcionado uma opção estética e confortável para o tratamento ortodôntico. No entanto, o design encapsulado dos alinhadores pode influenciar os músculos mastigatórios e comprometer a segurança do tratamento. Objetivo: Este estudo longitudinal preliminar teve como objetivo investigar se o uso de alinhadores ortodônticos afeta a força de mordida e a atividade mioelétrica dos músculos masseter superficial e temporal anterior. Métodos: Dez indivíduos participaram do estudo e foram submetidos a tratamento durante um período de acompanhamento de 8 meses. A raiz quadrada média (RMS), a frequência mediana de potência (FMP) dos sinais de superfície da eletromiografia (sEMG) e a força de mordida (kgf) foram registradas e normalizadas em relação à condição de pré-tratamento. Os dados foram analisados por análise de variância para medidas repetidas (ANOVA), com nível de significância estabelecido em 5%. Resultados: Tanto o masseter superficial quanto o temporal anterior apresentaram aumento da atividade do sinal sEMG durante o tratamento, com aumento acentuado desse último em comparação ao primeiro (p<0,05). Além disso, foi evidenciada uma diminuição significativa da força de mordida (p<0,05). Conclusões: Esse estudo preliminar observou que os alinhadores ortodônticos afetaram o padrão de recrutamento muscular dos músculos mastigatórios e reduziram o desempenho da mordida durante o período de acompanhamento de oito meses.

ABSTRACT

ABSTRACT Post-Chikungunya chronic arthralgia (PCCA) may lead to musculoskeletal repercussions and functional loss. The objective was to assess the upper limb physical disability and symptoms during daily, work, and leisure activities of women presenting PCCA compared to healthy controls (HC). This was a cross-sectional study conducted with 52 women. The participants were divided into PCCA (37) and HC (15) groups. Handgrip strength, range of motion, level of pain (numerical rating scale), and participants' physical disability and symptoms (Disabilities of the Arm, Shoulder, and Hand Questionnaire - DASH) were evaluated. Differences between groups were evaluated using the Students t-test and Pearson's correlations. The chi-square test was applied for categorical variables. The significance was set at α=0.05. The disease duration was 19.5±13.1 months. We found no differences between groups for peak force (PCAA:23.6±7.4kgf; HC: 24.5±6.2kgf; p=0.676). The results showed a significant difference between groups regarding range of motion (PCCA: 63.5±17.3o; HC: 77.2±9.6o), level of hand pain (PCCA: 5.8±2.2; HC: 0.4±1.5), and upper limbs functional levels (PCCA: 44.5±17.4; HC: 16.2±20.5). Participants related severe difficulty or inability to perform tasks such as opening a jar (78.4%), placing objects above head height (48.7%), doing heavy household chores (56.8%), and gardening (51.4%). Impairment in the upper limb physical function in daily, work, and leisure activities shows the higher prevalence in the long-term.


RESUMO A artralgia crônica pós-Chikungunya (ACPC) pode gerar repercussões musculoesqueléticas e perda funcional. Nesse sentido, o objetivo deste estudo foi avaliar a incapacidade física e os sintomas de membros superiores de mulheres com ACPC durante atividades diárias, laborais e de lazer comparadas aos controles saudáveis (CS). Para tanto, realizou-se um estudo transversal conduzido com 52 mulheres. As participantes foram divididas entre os grupos com ACPC (37) e CS (15). Foram avaliados força de preensão, amplitude de movimento (ADM), nível de dor (escala numérica de dor) e incapacidade física e sintomas por meio do Disabilities of the Arm, Shoulder and Hand Questionnaire (Dash). Diferenças entre os grupos foram avaliadas pelo teste t de Student e correlações de Pearson. O teste qui-quadrado foi utilizado para variáveis categóricas e α=0,05 foi estabelecido como nível de significância. Verificou-se que a duração da ACPC foi de 19,5±13,1 meses. Não houve diferença entre os grupos para a força pico (ACPC: 23,6±7,4kgf; CS: 24,5±6,2kgf; p=0,676). Os resultados demonstraram diferença significativa entre os grupos em termos de ADM (ACPC: 63,5±17,3o; CS: 77,2±9,6o), nível de dor nas mãos (ACPC: 5,8±2,2; CS: 0,4±1,5) e níveis funcionais dos membros superiores (ACPC: 44,5±17,4; CS: 16,2±20,5). As participantes relataram extrema dificuldade ou incapacidade para realizar tarefas como abrir um pote (78,4%), colocar objetos em um local acima da cabeça (48,7%), realizar atividades domésticas pesadas (56,8%) e atividades de jardinagem (51,4%). Conclui-se que a função física dos membros superiores durante as atividades diárias, laborais e de lazer constitui o maior comprometimento apresentado a longo prazo.


RESUMEN La artralgia crónica poschikunguña (ACPC) puede tener como efecto repercusiones musculoesqueléticas y pérdida funcional. En este sentido, el objetivo de este estudio fue evaluar la discapacidad física y los síntomas de miembros superiores de mujeres con ACPC durante las actividades diarias, laborales y de ocio en comparación con controles sanos (CS). Por ello, se realizó un estudio transversal con 52 mujeres. Las participantes se dividieron en los grupos ACPC (37) y CS (15). La fuerza de agarre, el rango de movimiento (ROM), el nivel de dolor (escala numérica de dolor), la discapacidad física y los síntomas se evaluaron mediante el Disabilities of the Arm, Shoulder and Hand Questionnaire (Dash). Las diferencias entre los grupos se evaluaron con la aplicación de la prueba t de Student y las correlaciones de Pearson. Se utilizó la prueba de chi-cuadrado para las variables categóricas y se estableció como nivel de significación α=0,05. Se encontró que la duración de la ACPC fue de 19,5±13,1 meses. No hubo diferencia entre los grupos para la fuerza máxima (ACPC: 23,6±7,4kgf; CS: 24,5±6,2kgf; p=0,676). Los resultados mostraron una diferencia significativa entre los grupos respecto al ROM (ACPC: 63,5±17,3o; CS: 77,2±9,6o), el nivel de dolor en la mano (ACPC: 5,8±2,2; CS: 0,4±1,5) y los niveles funcionales de miembros superiores (ACPC: 44,5±17,4; CS: 16,2±20,5). Las participantes informaron una extrema dificultad o incapacidad para realizar tareas como abrir un frasco (78,4%), poner objetos en un lugar más alto (48,7%), realizar actividades domésticas pesadas (56,8%) y actividades de jardinería (51,4%). Se concluyó que la función física de los miembros superiores durante las actividades diarias, laborales y de ocio constituye el mayor compromiso a largo plazo.

ABSTRACT

Introducción. El sedentarismo es un problema de salud pública, al ser factor de riesgo para ocho de las diez primeras causas de muerte en el mundo. Evaluar los niveles de sedentarismo con instrumentos óptimos se vuelve imprescindible para su correcto diagnóstico e intervención. Objetivo. Evaluar los niveles de sedentarismo en población universitaria colombia-na a través del cuestionario Sit Q7d-S y determinar su nivel de confiabilidad. Metodología. Se condujo un estudio cuantitativo, con aplicación tipo test re-test, con una muestra de 304 personas, con un error máximo de 5% y con 95% de con-fianza. La muestra estuvo conformada por 103 hombres (33,9%) y 201 mujeres (66,1%), estudiantes de una universidad colombiana con sede en cuatro ciudades diferentes (Cali, Neiva, Popayán y Medellín). Resultados. La población evaluada es sedentaria. Tienen comportamientos que indican que pasan más de dos horas de tiempo en posiciones sedentes, aumentado el riesgo de sufrir enfermedades crónicas no transmisibles. Se obtuvo un alfa de Cron-bach 0,64 para todos los ítems del cuestionario SIT-Q-7d-S, demostrando valores moderadamente aceptables para el uso del cuestionario. Conclusión. El cuestionario SIT-Q-7d-S es un instrumento con una fiabilidad de regular a moderada para evaluar niveles de sedentarismo en población universitaria. Así mismo, se evidencia que los niveles de inactividad en la población colombiana universitaria indican que es una población sedentaria, lo que se relaciona con que pasan más de dos horas de tiempo en pantalla y pasan entre una, dos o más de tres horas sentados realizando su ocupación


Introduction. Sedentary lifestyle is a public health problem, as it is a risk factor for eight of the ten leading causes of death in the world. Assessing sedentary lifestyle levels with optimal instruments becomes essential for its correct diagnosis and intervention.Aim. To evaluate the levels of sedentary lifestyle in the Colombian university pop-ulation through the Sit Q7d-S questionnaire and to determine its level of reliability.Methodology. A quantitative study was conducted, using a test re-test type applica-tion, with a sample of 304 people with a 5% maximum error and 95% confidence. The sample size included 103 men (33.9%) and 201 women (66.1%), who are stu-dents at a Colombian university located in four different cities (Cali, Neiva, Popayan, and Medellin).Results. The evaluated population is sedentary, as they have behaviors that indicate they spend more than two hours of time in seated positions, increasing the risk of suffering from chronic non-communicable diseases. A Cronbach's alpha of 0.64 was obtained for all the items of the SIT-Q-7d-S questionnaire, showing moderately ac-ceptable values for the use of the questionnaire.Conclusion. The SIT-Q-7d-S questionnaire is an instrument with low to moderate reliability to assess levels of sedentary lifestyle in the university population. Likewise, it is evident that the levels of inactivity in the Colombian university population indi-cate that it is a sedentary population. This is related to the fact that they spend more than two hours on screen time and spend between one, two or more than three hours doing their job in a sitting position

ABSTRACT

Coronavirus infection (SARS-CoV-2), is a pandemic disease declared by the World Health Organization (WHO). This disease reports a high risk of contagion, especially by the transmission of aerosols in health care workers. In this scenario, aerosol exposure is increased in various procedures related to the airway, lungs, and pleural space. For this reason, it is important to have recommendations that reduce the risk of exposure and infection with COVID-19. In this document, a team of international specialists in interventional pulmonology elaborated a series of recommendations, based on the available evidence to define the risk stratification, diagnostic methods and technical considerations on procedures such as bronchoscopy, tracheostomy, and pleural procedures among others. As well as the precautions to reduce the risk of contagion when carrying out pulmonary interventions.

ABSTRACT

INTRODUÇÃO: Poucos estudos discutem as reações corporais de indivíduos saudáveis no momento em que os exercícios em superfícies instáveis estão sendo executados, embora os efeitos do treinamento ­ efeitos crônicos do exercício- sejam bastante estudados. OBJETIVO: Descrever a cinemática articular do tornozelo e retropé durante essa interação. MÉTODOS: Dezoito voluntários participaram do estudo. A posição articular da região do tornozelo foi estudada em três superfícies: Airex® Balance-pad, BOSU® e chão (controle). Para análise estatística, utilizou-se ANOVA e Pós-teste de Tuckey, considerando um nível de significância menor que 0,05. RESULTADOS: A posição articular da região tornozelo no plano sagital foi diferente no BOSU® em relação ao Airex® (p < 0.001) e ao chão (p < 0.001). O tornozelo ficou em posição mais próxima à neutra no AIREX® e no chão. Com o BOSU, a dorsiflexão foi acentuada. Não houve diferença da posição média no no plano frontal. A variabilidade da posição da região do tornozelo foi maior no BOSU® que no Airex® (p < 0.001) e no chão (p < 0.001), tanto no plano sagital, quanto no plano frontal. A frequência média de deslocamento da posição articular na região do tornozelo no plano sagital foi maior no BOSU® que no chão (p < 0.001); e no plano frontal, para o retropé, foi maior no BOSU® que no Airex® (p < 0.001) e chão (p < 0.001). CONCLUSÃO: Houve diferença no comportamento articular da região do tornozelo na condição BOSU® em relação às demais nas superfícies utilizadas, havendo um aumento das oscilações articulares no processo de controle postural em condições mais instáveis e maior dosiflexão no BOSU®.

INTRODUCTION: There are few studies approaching the bodily reactions of healthy individuals while performing exercises on unstable surfaces, although the training effects ­ exercise chronic effects - are well studied. OBJECTIVE: The goal of this study is to describe the ankle and rear foot region osteoarticular kinematic during this interaction. METHODS: Eighteen volunteers participated in the study. The ankle region osteoarticular displacement was studied in three different surfaces: AIREX® Balance-pad, BOSU® and Ground (control). Statistical analysis was performed using ANOVA and Tukey test, considering a significance level of 0.05. RESULTS: The position of the ankle joint in the sagittal plane was greater in the BOSU® than in the AIREX® (p < 0.001) and ground (p < 0.001). The ankle was close to the neutral position in the AIREX® and on the ground. With BOSU, the dorsiflexion was accentuated. Considering the frontal plane, there was no difference in the rear foot position. Moreover, the variability in the ankle region position in sagittal and frontal planes was higher in BOSU® than AIREX® (p < 0.001) and ground (p < 0.001). The mean frequency of the ankle position in the sagittal plane was greater in the BOSU® than on the ground (p < 0.001), and, in frontal plane, the rear foot frequency displacement was largest in the BOSU® than in the AIREX® (p < 0.001) and on the ground (p < 0.001). CONCLUSION: There were observed differences in ankle region postural control strategies in the BOSU® condition when compared with the other surfaces tested. The ankle and rear foot oscillations increase and there is a greater dorsiflexion for the postural control under the most unstable condition - BOSU. [AU]

ABSTRACT

Abstract Introduction The aim of this study was to propose a method of electrodes positioning on the superficial masseter and anterior temporalis muscles for surface electromyographic (sEMG) recordings in order to overcome some known methodological constraints. Methods Fifteen volunteers with normal occlusion participated in two experimental sessions within a 7 day-period. Surface electrodes were placed on two different locations that were based on palpable and individual anatomical references. Surface EMG signals (2000 Hz per channel; A/D: 16 bits; gain: 2000 X; band-pass filter: 20-500 Hz) were recorded under three conditions: mandibular rest position, 30% and 100% of maximum voluntary bite force. Three measurements of maximal bite force were taken by using a force transducer positioned over the lower right first molar region and the highest record was taken into account. The root mean square value was considered for analysis. Intraclass correlation coefficients (ICCs), paired t test, and the Bland-Altman method comprised the statistical analyses. The level of significance was set at 0.05. Results ICC records for right and left masseter and anterior temporalis muscles at T0 (first sEMG record) and T7 (second sEMG record) intervals were significantly different (p<0.05). The results showed satisfactory to excellent reproducibility of RMS values at rest, MVBF and 30% MVBF, as well as for MVBF in kgf. Conclusion The results showed reliable reproducibility for the sEMG signal recording in masseter and anterior temporalis muscles from the protocols presented and under the three conditions investigated.

ABSTRACT

Background: Aim: To compare the concentration of secretory immunoglobulin-A (sIgA) in young adults with average or excellent aerobic capacity before and after a cardiopulmonary graded exercise test. Methods: Participants were nine apparently healthy physically active males (Mean age = 21.3 ± 2.1 yr.), randomly allocated in two groups based on their VO2max: a) average aerobic capacity (AEC, n = 5) or b) excellent aerobic capacity (EAC, n = 4). Participants performed the Bruce protocol to determine their aerobic capacity. The sIgA was measured before the test, immediately after the test and 60-, 120-, 240-, and 1440-min after the test. Results: Mixed factorial 2 x 6 ANOVA indicated no significant interactions between groups and measurements (p = 0.956), and main effect groups on sIgA (AEC = 85.4 ± 19.3 μg/mL vs. EAC = 79.2 ± 21.5 μg/mL, p = 0.836). Tukey's post hoc analysis revealed significant differences measurement obtained immediately after the test and between the initial measurement (p = 0.020), 60-min (p = 0.030), 240-min (p = 0.016), and 1440-min (p = 0.028) following the test. Conclusion: There is no change in sIgA kinetics depending on the aerobic capacity of the participants following an aerobic capacity cardiopulmonary graded exercise test.


Introducción. Objetivo: Comparar la cinética en la concentración de inmunoglobulina A salival (IgAs) en adultos jóvenes con capacidad aeróbica promedio (n: 5) o excelente (n: 4) antes y después de una prueba de esfuerzo. Método: 9 adultos jóvenes (edad 21,3 ± 2,1), divididos de acuerdo su VO2máx, realizaron una prueba de esfuerzo mediante el protocolo de Bruce. La concentración de IgAs fue determinada mediante el Salimetrics IgA Kit®, evaluando inicial, inmediatamente finalizada la prueba, +60, +120, +240, +1.440 min. Resultados: La prueba ANOVA 2x6 mixta indicó que no existieron interacciones significativas entre grupos y mediciones (p = 0,956). Tampoco se encontró una diferencia significativa en la media de IgAs en los grupos (Promedio = 85,4 ± 19.3 μg/mL vs Excelente=79,2 ± 21.5 μg/mL, p = 0,836). Independientemente de las mediciones, el análisis post hoc de Tukey indicó que las diferencias se encontraron en la medición obtenida inmediatamente después de la prueba y entre la medición inicial (p: 0,020), la medición obtenida 60 min (p: 0,030), 240 min (p: 0,016) y 1.440 min (p = 0,028) posteriores a la prueba. Conclusión: Los datos encontrados sugieren que no hay un cambio en la concentración de IgAs a través del tiempo en función de la capacidad aeróbica de los participantes.

ABSTRACT

La artritis reumatoide (AR) es una enfermedad sistémica crónica y autoinmune, que afecta principalmente a las articulaciones sinoviales. Al igual que ocurre con muchas enfermedades autoinmunes, la etiología de la AR es multifactorial y desconocida. La susceptibilidad genética es evidente en AR, situando su heredabilidad en aproxima-damente el 60%. La importancia del conocimiento de los factores genéticos asociados con la AR se sitúa en la contribución a la comprensión de los mecanismos patogénicos de la enfermedad, así como a su aplicación clínica que nos acerque a un tratamiento más personalizado de los pacientes por medio de marcadores de riesgo, diagnóstico y/o pronóstico. En este artículo se revisan los factores genéticos de la AR, y se hace una aproximación a la situación en poblaciones latinoamericanas en general, y chile-na en particular.


Rheumatoid arthritis (RA) is an autoimmune inflammatory rheumatic disease that affects many tissues and organs, mainly synovial joints. Like many autoimmune dis-eases, the etiology of RA is multifactorial and unknown. Genetic susceptibility is evi-dent in RA, with its heritability around the 60%.The relevance of the knowledge of the genetic factors associated with RA relies on its contribution to the understanding of the pathological mechanisms of the disease, and the clinical applicability. This better understanding let us develop a more personalized treatment through genetic markers for risk, diagnostic and prognostic. In this paper, genetic factors of RA are reviewed and a general view of the Latin American populations, and particularly Chilean, is made.

ABSTRACT

Resumen La mucormicosis es una infección causada por hongos del orden de los mucorales; las infecciones causadas por estos hongos generalmente se adquieren por vía respiratoria ya que las esporas de estos se encuentran en el ambiente. En pacientes inmunocomprometidos o diabéticos descompensados, estos microorganismos pueden causar cuadros fatales. Puede presentarse en varias localizaciones, en este caso se tratará la localización pulmonar. La fiebre, la hemoptisis y el infarto tisular son característicos de la mucormicosis pulmonar. Radiológicamente, se puede encontrar consolidación lobar, lesiones aisladas, enfermedad nodular y cavitación. Una vez realizado el diagnóstico de mucormicosis de cualquier localización, se deben identificar los factores predisponentes y corregirlos o atenuarlos. En esta ocasión se presenta el caso clínico de una paciente de 61 años de edad con diabetes mellitus tipo 2 (DM2) de 10 años de evolución que ingresa al servicio de urgencias de esta institución con descontrol glucémico de 520 mg/dL, acompañado de fiebre y con cuadro clínico de infección de vías respiratorias en tratamiento. Se realiza la presentación del caso, su comparación con la literatura disponible y las conclusiones a las que se llegaron.


Abstract Mucormycosis is an infection caused by organisms that belong to a group of fungi called Mucoromycotina in the order Mucorales; Infections caused by these microorganisms, are usually acquired through the respiratory route since the spores of fungi are found in the environment. These infections are more common among people with a weakened immune system or diabetic people, and they could be fatal. Mucormycosis can be found in several localizations but this case will focus specifically in the lung. The symptoms associated with it are fever, hemoptysis, and tissular infarct. Radiographically, lobar consolidation, isolate mass, nodular component and cavitation can be found. Once the diagnostics is made, in any location, its important to identify the risk factors, and try to correct or improve them. In this occasion, the we present the case of a 62-years-old female, with diabetes mellitus type 2 with and 10 years of evolution,. She arrives to the emergency room of this institution with uncontrolled blood glucose (520 mg / dL), accompanied by fever.and respiratory infection, and is treated by a multidisciplinary team (internal medicine, surgery and infectology). This is the presentation of the case, its comparison with the available literature and the conclusions of the author.

ABSTRACT

Objetivo ­ Identificar a situação cronológica de irrupção dos terceiros molares por meio de radiografias panorâmicas digitais, e correlacioná-la com a faixa etária e a presença ou não do primeiro molar. Métodos ­ Analisou-se a prevalência de irrupção dos terceiros molares superiores e inferiores em radiografias panorâmicas digitais de 1341 pacientes de ambos os gêneros,com faixa etária de 17 a 23 anos, e a presença ou não dos primeiros molares. Resultados ­ Não houve distinção por gênero entre os pacientes. Pacientes entre 17 e 21 anos tiveram maiores possibilidades de irrupção dos terceiros molares e de 21 a 23 anos, a irrupção tornou-se mais rara, ou seja, praticamente nula, descartando-se assim a possibilidade de sua irrupção. A presença ou não dos primeiros molares alteraram os resultados quanto a irrupção dos terceiros molares. Quando ausente o primeiro molar, observou-se um maior índice de irrupção. Conclusões ­ Houve diferença estatística (p>0,0004) na comparação de irrupção dos terceiros molares em relação à presença ou ausência do primeiro molar. A presença do primeiro molar interfere na incidência de irrupção do terceiro molar do mesmo lado. Pacientes, independente da idade, que apresentaram ausência do primeiro molar, apresentaram menores índices de não irrupção do terceiro molar do mesmo lado.


Objective ­ To identify the chronological situation of eruption of third molars and correlates it with the band age and the presence or absence of the first molar. Methods ­ It was analyzed the prevalence of eruption of upper and lower third molars in digital panoramic radiographs 1341 patients aged 17-23 years and the presence or absence of first molars. Results ­ There was no difference by gender among patients. Patients between 17 and 21 years had higher chances of eruption of third molars and 21-23 years, the outbreak is rare or practically zero, thus ruling out the possibility of its emergence, and presence or absence of first molars alter results as the eruption of third molars, where there was a major outbreak index. Conclusions ­ IWas no statistical difference (p> 0.0004) in the third molar eruption of comparison for the presence or absence of the first molar. It presence interfere in the incidence of eruption of third molar on the same side. Patients independently of age, who presented absence of the first molar, had lower rates of non eruption of the third molar on the same side

ABSTRACT

Objetivo: Determinar el efecto del alopurinol en las adherencias peritoneales al colocar una malla de polipropileno. Sede: Cirugía Experimental de la Universidad de Guanajuato. Diseño: Estudio experimental, prospectivo, comparativo, controlado, doble ciego, con asignación al azar. Análisis estadístico: χ². Material y métodos: Se compararon dos grupos de 30 ratas Wistar cada uno, a quienes se les colocó una malla de polipropileno: el grupo A, sin tratamiento versus el grupo B, alopurinol a 25 mg/kg/día por sonda orogástrica. Resultados: Este estudio determinó que la prevalencia de adherencias protésicas-peritoneales viscerales en ratas Wistar, al colocar una malla de polipropileno, es del 100% sin tratamiento y con alopurinol. Conclusiones: No obtuvimos diferencia estadística del efecto beneficioso del alopurinol en la prevención de adherencias, esto puede hablarnos de que la acción del alopurinol sólo se ejerce en la prevención de adherencias cuando su etiología es la isquemia y no debido a la presencia de reacción a cuerpo extraño de tipo granulomatoso.


Objective: To determine the effect of allopurinol on peritoneal adhesions when placing a polypropylene mesh. Setting: Experimental Surgery Unit of the University of Guanajuato, México. Design: Experimental, prospective, comparative, controlled, double-blinded, randomized assignment study. Statistical analysis: χ². Material and Methods: We compared two groups of 30 Wistar rats each, in which we placed a polypropylene mesh: Group A, without treatment, versus group B with allopurinol at mg/kg per day administered through an orogastric catheter. Results: This study determined that the prevalence of visceral peritoneal-prosthetic adhesions in Wistar rats when placing a polypropylene mesh is of 100% with and without allopurinol treatment. Conclusions: We did not obtain statistical differences of the beneficial effect of allopurinol in preventing adhesions, this can indicate that allopurinol's effect is only exerted in preventing adhesions when they are due to ischemia but not when they are caused by a granulomatous-type foreign body reaction.

ABSTRACT

A cirurgia de lateralização do nervo alveolar inferior se apresenta como uma alternativa para tratamento de mandíbulas atróficas, mas enfrenta como obstáculo à técnica a incidência da parestesia. Este trabalho objetivou relatar um caso clínico da técnica de lateralização de nervo alveolar inferior com instalação de implantes dentais, associada ao uso de instrumento piezoelétrico, laserterapia e de um composto polivitamínico com regressão da média da duração da parestesia baseado em achados científicos prévios. Esta nova metodologia foi desenvolvida a partir de observação clínica ao longo dos anos, que levou a pesquisas laboratoriais in vitro e in vivo no Instituto de Ciências Biomédicas da USP e no Centro de Ciências e Tecnologia de Materiais do Ipen-USP, que culminaram em teses de doutoramento e pós-doutoramento, antes de ser aplicadas em clínica, sempre visando uma melhoria na qualidade de vida dos pacientes. Os resultados clínicos demonstrados no presente trabalho estão de acordo com os achados laboratoriais, confirmando as pesquisas e levando a uma nova perspectiva na utilização da técnica e na regressão do dano neurossensor.


The surgical procedure of inferior alveolar nerve lateralization is an alternative treatment for atrophic mandibles but a potential drawback in this technique is the incidence of paresthesia. The purpose of this work is to present a case report of inferior alveolar nerve lateralization for dental implants insertion using piezoelectric device, lasertherapy and a polyvitaminic compound to reduce the rate of paresthesia endurance based on previous scientifi c data. This new methodology was developed by long-term clinical observation and led to the development of in vitro and in vivo laboratory research that took place at Instituto de Ciências Biomédicas, USP and at the Centro de Ciências e Tecnologia de Materiais at Ipen-USP, resulting in a PhD thesis and post-doctoral thesis, before clinical trials, always aiming the improvement of quality of human life. Clinical results shown in this work are consonant to those found in laboratory and leads to a new perspective on the surgical technique and neurosensory impairment regression.

ABSTRACT

A eletromiografia de superfície (sEMG), apesar de amplamente utilizada em investigações biomecânicas, ainda apresenta inúmeros questionamentos sobre a influência das distâncias intereletrodos (DIE) na morfologia do sinal, principalmente em contrações isotônicas. Logo, muitos dos trabalhos desenvolvidos ainda se limitam ao âmbito do laboratório de pesquisa, onde é possível estabelecer maior controle nos protocolos de registro e análise, o que não é comumente observado na prática clínico-desportiva. Dessa forma, o objetivo do estudo foi examinar os efeitos de dois protocolos de colocação de eletrodos e a realização de contrações isotônicas no domínio da frequência do sinal de sEMG. Quinze sujeitos do sexo masculino (idade: 22,8 ± 3,5 anos), todos destros, realizaram contrações dinâmicas do bíceps braquial direito com carga estimada em 20 por cento da contração voluntária máxima em três diferentes cadências (30, 45, 60bpm). Os sinais de sEMG foram registrados por meio de dois canais, cujas DIEs foram de 4,2 e 13cm, respectivamente. A avaliação dos sinais de sEMG foi baseada na frequência mediana do espectro de potencial do sinal, calculado via transformada rápida de Fourier. A DIE e a cadência foram definidas como fatores (ANOVA two-way; α = 0,05). Não foram observadas diferenças estatísticas e qualquer interação entre ambos os fatores nas três cadências (P > 0,05). Sugere-se que, independentemente da distância utilizada entre os eletrodos, uma investigação no domínio da frequência do sinal de sEMG em tarefas dinâmicas seja evitada, mesmo a partir de DIEs reduzidas, como é sugerido pela literatura, dado que variações no torque e no comprimento muscular podem corromper o sinal e, portanto, sua interpretação.


Surface electromyography (SEMG), despite being widely used in biomechanical investigations, still presents massive questioning about the influence of the distance of the inter-electrodes (DIE) in the signal morphology, especially in isotonic contractions. Thus, much of the research developed is still limited to the laboratory, where it is possible to establish better control over the recording and analysis protocols, which is not commonly observed in the clinical-sportive practice. Therefore, the aim of this study was to examine the effects of two electrodes placement protocols and the performance of isotonic contractions in the SEMG sign frequency domain. Fifteen right-handed male subjects (aged 22.8 ± 3.5 years) performed dynamic contractions of the right brachial biceps with load estimated in 20 percent of the maximum voluntary contraction in three different cadences (30, 45 and 60 bpm). The SEMG signals were registered by two channels with DIEs of 4.2 and 13 cm, respectively. The SEMG signals assessment was based on the median frequency of the potential spectrum of the signal, calculated via fast Fourier transform. DIE and cadence were defined as factors (two-way ANOVA; α = 0.05). No statistical differences or any interaction between both factors were observed in the three cadences (P> 0.05). Regardless of the distance used between electrodes, an investigation in the SEMG signal frequency domain in dynamic tasks should be avoided, even from reduced DIEs, as suggested in the literature, since variations in the torque and muscular length may disrupt the signal and hence its interpretation.
