Título: Temblores posanestésicos / Post-anesthetic shivering
Fonte: Rev. cuba. anestesiol. reanim;15(3):243-248, sept.-dic. 2016.
Idioma: es.
Resumo: Introducción: los temblores posanestésico son causa de una de las mayores insatisfacciones durante el posoperatorio inmediato. Es un fenómeno frecuente, potencialmente perjudicial por aumentar la demanda metabólica de oxígeno. Objetivo: hacer una actualización sobre los temblores Posanestésicos y su profilaxis. Métodos: constituyen una actividad muscular oscilatoria para aumentar la producción de calor. Su etiología es desconocida, aunque se le atribuyen numerosas causas. Su frecuencia oscila entre 6,3 y 66 por ciento. De 5 a 65 por ciento relacionadas con anestesia general y 30 por ciento con anestesia regional. Con anestesia general, la temperatura central disminuye entre 0,5 y 1,5 °C, en la primera hora posterior a la inducción, al igual que en la anestesia regional. Este mecanismo se produce por redistribución del calor del centro a la periferia. Todos los anestésicos, opioides y sedantes disminuyen la vasoconstricción y el control autonómico de la regulación térmica y facilitan la hipotermia. Se presenta con mayor frecuencia en pacientes jóvenes, del sexo masculino, en los cuales se administraron agentes anestésicos halogenados, con tiempo anestésico quirúrgico prolongado. Numerosos artículos señalan, que en las especies homeotérmicas se presenta un sistema termorregulador que coordina la defensa contra la temperatura ambiental, para mantener la temperatura interna en un umbral estrecho. La combinación de agentes inductores anestésicos y exposición al ambiente frío hacen que los pacientes presenten temblores posanestésicos. Su profilaxis está dada por el uso de meperidina, clonidina y tramadol. La ketamina, es una fenciclidina, que produce disociación electrofisiológica entre los sistemas límbico y cortical. Se une a dos dianas moleculares en el encéfalo: las terminaciones dopaminérgicas en el núcleo accumbens y los receptores de N-metil de aspartato. Cuando la ketamina se une a dichos receptores, inhibe la liberación de dopamina. Conclusiones: los temblores Posanestésicos constituyen un efecto adverso de la anestesia que pueden ser evitados. La ketamina, por su mecanismo de acción parece jugar un papel en su profilaxis, pues al bloquear dicho receptor se infiere que es posible que module, en alguna medida, la regulación térmica en varios niveles(AU)

Introduction: post-anesthetic shivering is caused by one of the greatest dissatisfactions during the immediate postoperative period. It is a common event, also potentially damaging because it increases the metabolic demand for oxygen. Objective: To make an update on post-anesthetic shivering and its prophylaxis. Methods: It constitutes an oscillatory muscle activity to increase heat production. Its etiology is unknown, although it is attributed to many causes. Its frequency varies between 6.3 and 66 percent. 5 to 65 percent are related to general anesthesia, and 30 percent to regional anesthesia. Under general anesthesia, the central temperature decreases from 0.5 to 1.5 °C in the first hour after induction, as in regional anesthesia. This mechanism is caused by redistribution of heat from the center to the periphery. All anesthetics, opioids and sedatives decrease vasoconstriction and the autonomic control of thermal regulation, and facilitate hypothermia. It occurs most often in young patients, male, to whom halogenated anesthetic agents are administered with anesthetic prolonged surgical time. Many items indicate that in the homeothermic species a thermoregulator system is present, which coordinates the defense against the environmental temperature to maintain the internal temperature in a narrow threshold. The combination of anesthetic inducing agents and exposure to cold environment make patients present post-anesthetic shivering. Prophylaxis is attained by using meperidine, clonidine and tramadol. Ketamine is a phencyclidine, which produces electrophysiological dissociation between the limbic and cortical systems. It is bound to two molecular targets in the brain: dopaminergic terminals in the accumbens nucleus and the N-methyl aspartate receptor. When ketamine binds to these receptors, it inhibits the release of dopamine. Conclusions: Post-anesthetic shivering constitutes an adverse effect of anesthesia, which can be avoided. Ketamine, for its action mechanism, seem to play a role in prevention, because when such receptor is blocked, it is inferred to module, at some extent, thermal regulation at various levels(AU)

Resumo: Abstract Objective To compare the results of the standard urotherapy alone and associated with pelvic floor muscle training alone, and in combination with oxybutynin in treatment of nonmonosymptomatic nocturnal enuresis. Methods A total of 38 children aged 5 to 10 years were randomized into three groups: Group I (n=12) that was submitted to standard urotherapy; Group II (n=15), standard urotherapy associated with pelvic floor muscle training; and Group III (n=11), standard urotherapy associated with pelvic floor muscle training and oxybutynin; the treatment lasted 12 weeks. The assessment tools used were playful bladder diary, and a 48-hour bladder diary, before and after treatment. After 2 years, patients were assessed by telephone using a standardized questionnaire. Results The data of children from the three groups were homogeneous at baseline. After 12-week treatment, all children showed improved symptoms and signs of nonmonosymptomatic nocturnal enuresis, but the differences were not significant among the groups. After 2 years, the three groups showed maintenance of treatment results, but no differences among them. Conclusion All treatment modalities were effective regarding improved enuresis and lower urinary tract symptoms, but the sample was not large enough to show differences among groups.

Resumo Objetivo Comparar os resultados da uroterapia padrão isolada e associada ao treinamento dos músculos do assoalho pélvico isoladamente e em combinação com a oxibutinina no tratamento da enurese noturna não monossintomática. Métodos Trinta e oito crianças entre 5 e 10 anos de idade foram randomizadas em três grupos: Grupo I (n=12) realizou uroterapia padrão; Grupo II (n=15) realizou uroterapia padrão associada ao treinamento muscular do assoalho pélvico; e Grupo III (n=11) realizou uroterapia padrão associada ao treinamento muscular do assoalho pélvico e oxibutinina. O tratamento teve duração de 12 semanas. Os instrumentos de avaliação foram diário miccional lúdico e diário miccional de 48 horas, antes e depois do tratamento. Após 2 anos, os pacientes foram avaliados por telefone, usando um questionário padronizado. Resultados Os dados das crianças dos três grupos eram homogêneos no início do estudo. Após 12 semanas de tratamento, todas as crianças apresentaram melhora em relação aos sinais e sintomas de enurese noturna não monossintomática, mas as diferenças não foram significativas entre os grupos. Depois de 2 anos, os resultados do tratamento se mantiveram nos três grupos, mas não houve diferenças entre os grupos. Conclusão As três modalidades de tratamento foram eficazes na melhora da enurese e dos sintomas do trato urinário inferior, mas o tamanho da amostra não foi grande o suficiente para mostrar diferenças entre os grupos.

Título: Força muscular do assoalho pélvico em mulheres com queixas de disfunção pélvica / Pelvic floor muscle strength in women with pelvic dysfunction complaint
Fonte: Fisioter. Bras;22(3):425-441, Jul 15, 2021.
Idioma: pt.
Resumo: A disfunção do assoalho pélvico envolve condições nosológicas, como incontinência urinária e disfunção sexual, com impacto negativo na qualidade de vida. O presente estudo objetivou avaliar a força muscular do assoalho pélvico de mulheres com disfunção pélvica. Trata-se de desenho analítico transversal realizado com uma amostra de conveniência de 167 mulheres com queixas de disfunções musculares do assoalho pélvico. Foram analisadas características sociodemográficas e clínicas, qualidade de vida relacionada à incontinência e força muscular pélvica. Estatísticas univariadas e bivariadas foram calculadas. A idade média das mulheres foi de 50,2 anos. A maioria foi classificada com impacto muito grave (76,6%) na qualidade de vida relacionada à incontinência, 41 (24,6%) apresentaram contração muscular não sustentada e 7 (4,2%) apresentaram contração. Associações significativas foram identificadas entre força muscular pélvica e idade (p = 0,025), menopausa (p = 0,039) e histerectomia (p = 0,026). A pesquisa permitiu concluir que os fatores de risco responsáveis por problemas no assoalho pélvico podem ser considerados cruciais para avaliar o nível de impacto da incontinência urinária e sua evolução como resultado de intervenções precoces, simples e de baixo custo na atenção primária à saúde. As disfunções do assoalho pélvico afetam negativa e substancialmente a qualidade de vida das mulheres. (AU)

Pelvic floor dysfunction involves nosological conditions, such as urinary incontinence and sexual dysfunction, which have a negative impact on quality of life. This study aimed to evaluate pelvic floor muscle strength of women with pelvic dysfunction. This is an analytical cross-sectional performed design with a convenience sample of 167 women with complaints of pelvic floor muscle dysfunctions. Sociodemographic and clinical characteristics, quality of life related to incontinence and pelvic muscle strength were analyzed. Univariate and bivariate statistics were calculated. The mean age of women was 50.2 years. Most were classified having a very severe impact (76.6%) on incontinencerelated quality of life, 41 (24.6%) presented non-sustained muscle contraction and 7 (4.2%) presented in contraction. Significant associations were identified between pelvic muscle strength and age (p = 0.025), menopause (p = 0.039) and hysterectomy (p = 0.026). This study allowed us to conclude that the risk factors responsible for pelvic floor problems can be considered crucial to assess the level of impact of urinary incontinence and its evolution as a result of early, simple and low cost interventions in primary health care. Pelvic floor dysfunctions affect negatively and substantially the quality of life of women. (AU)

Título: La rigidez cadavérica, el espasmo cadavérico y tipos de fibras musculares / The cadaveric rigidity, the cadaveric spasm and types of muscle fibers
Fonte: Rev. Asoc. Méd. Argent;133(1):12-20, mar. 2020. graf, tab.
Idioma: es.
Resumo: 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)

Título: Effect of S-methyl-l-thiocitrulline dihydrochloride on rat micturition reflex
Fonte: Int. braz. j. urol;42(5):1018-1027, Sept.-Oct. 2016. tab, graf.
Idioma: en.
Resumo: ABSTRACT Objective: To evaluate the effect of neuronal nitric oxide synthase on the striated urethral sphincter and the urinary bladder. Materials and Methods: A coaxial catheter was implanted in the proximal urethra and another one in the bladder of female rats, which were anesthetized with subcutaneous injection of urethane. The urethral pressure with saline continuous infusion and bladder isovolumetric pressure were simultaneously recorded. Two groups of rats were formed. In group I, an intrathecal catheter was implanted on the day of the experiment at the L6-S1 level of the spinal cord; in group II, an intracerebroventricular cannula was placed 5-6 days before the experiment. Results: It was verified that the group treated with S-methyl-L-thio-citrulline, via intrathecal pathway, showed complete or partial inhibition of the urethral sphincter relaxation and total inhibition of the micturition reflexes. The urethral sphincter and the detrusor functions were recovered after L-Arginine administration. When S-methyl-L-thio-citrulline was administered via intracerebroventricular injection, there was a significant increase of urethral sphincter tonus while preserving the sphincter relaxation and the detrusor contractions, at similar levels as before the use of the drugs. Nevertheless there was normalization of the urethral tonus when L-Arginine was applied. Conclusions: The results indicate that, in female rats anaesthetized with urethane, the nNOS inhibitor administrated through the intrathecal route inhibits urethral sphincter relaxation, while intracerebroventricular injection increases the sphincter tonus, without changing bladder function. These changes were reverted by L-Arginine administration. These findings suggest that the urethral sphincter and detrusor muscle function is modulated by nitric oxide.

Resumo: ABSTRACT Introduction and objectives: Several studies have been investigated co-activation can enhance the effectveness of PFM training protocols allowing preventive and therapeutic goals in pelvic floor dysfunctions. The objective of the present study was to investigate if an abdominal-pelvic protocol of training (APT) using gametherapy would allow co-activation of PFM and transversus abdominis/oblique internal (TrA/OI) muscles. Patients and methods: Twenty-five nulliparous, continent, young females, with median age 24.76 (±3.76) years were evaluated using digital palpation (DP) of PFM and surface electromyography of PFM and TrA/OI simultaneously, during maximal voluntary contraction (MVC), alternating PFM and TrA/OI contraction requests. All women participated on a supervised program of APT using gametherapy, that included exercises of pelvic mobilization associated to contraction of TrA/OI muscles oriented by virtual games, for 30 minutes, three times a week, in a total of 10 sessions. Electromyographic data were processed and analyzed by ANOVA - analysis of variance. Results: When MVC of TrA/OI was solicited, it was observed simultaneous increase of electromyographic activity of PFM (p=0.001) following ATP. However, EMG activity did not change significantly during MVC of PFM. Conclusion: Training using gametherapy allowed better co-activation of pelvic floor muscles in response to contraction of TrA, in young nulliparous and continent women.

Título: Can intraurethral stimulation inhibit micturition reflex in normal female rats?
Fonte: Int. braz. j. urol;42(3):608-613graf.
Idioma: en.
Resumo: ABSTRACT Objective The study was designed to determine the effect of low frequency (2.5Hz) intraurethral electrical stimulation on bladder capacity and maximum voiding pressures. Materials and Methods The experiments were conducted in 15 virgin female Sprague-Dawley rats (220–250g). The animals were anesthetized by intraperitoneal injection of urethane (1.5g/kg). Animal care and experimental procedures were reviewed and approved by the Institutional Animal Care and Use Committee of Antwerp University (code: 2013-50). Unipolar square pulses of 0.06mA were used to stimulate urethra at frequency of 2.5Hz (0.2ms pulse width) in order to evaluate the ability of intraurethral stimulation to inhibit bladder contractions. Continuous stimulation and intermittent stimulation with 5sec ‘‘on’’ and 5sec ‘‘off’’ duty cycle were applied during repeated saline cystometrograms (CMGs). Maximum voiding pressures (MVP) and bladder capacity were investigated to determine the inhibitory effect on bladder contraction induced by intraurethral stimulation. Results The continuous stimulation and intermittent stimulation significantly (p<0.05) decreased MVP and increased bladder capacity. There was no significant difference in MVP and bladder capacity between continuous and intermittent stimulation group. Conclusions The present results suggest that 2.5Hz continuous and intermittent intraurethral stimulation can inhibit micturition reflex, decrease MVP and increase bladder capacity. There was no significant difference in MVP and bladder capacity between continuous and intermittent stimulation group.

Título: Effects of nitric oxide inhibitors in mice with bladder outlet obstruction
Fonte: Int. braz. j. urol;43(2):356-366, Mar.-Apr. 2017. tab, graf.
Idioma: en.
Resumo: ABSTRACT Purpose To investigate the lower urinary tract changes in mice treated with L-NAME, a non-selective competitive inhibitor of nitric oxide synthase (NOS), or aminoguanidine, a competitive inhibitor of inducible nitric oxide synthase (iNOS), after 5 weeks of partial bladder outlet obstruction (BOO), in order to evaluate the role of constitutive and non-constitutive NOS in the pathogenesis of this experimental condition. Materials and Methods C57BL6 male mice were partially obstructed and randomly allocated into 6 groups: Sham, Sham + L-NAME, Sham + aminoguanidine, BOO, BOO + L-NAME and BOO + aminoguanidine. After 5 weeks, bladder weight was obtained and cystometry and tissue bath contractile studies were performed. Results BOO animals showed increase of non-voiding contractions (NVC) and bladder capacity, and also less contractile response to Carbachol and Electric Field Stimulation. Inhibition of NOS isoforms improved bladder capacity and compliance in BOO animals. L-NAME caused more NVC, prevented bladder weight gain and leaded to augmented contractile responses at muscarinic and electric stimulation. Aminoguanidine diminished NVC, but did not avoid bladder weight gain in BOO animals and did not improve contractile responses. Conclusion It can be hypothesized that chronic inhibition of three NOS isoforms in BOO animals leaded to worsening of bladder function, while selective inhibition of iNOS did not improve responses, what suggests that, in BOO animals, alterations are related to constitutive NOS.

Título: The effects of motor adaptation on ankle isokinetic assessments in older drivers
Fonte: Clinics;73:e303, 2018. tab.
Idioma: en.
Projeto: Foundation for Research Support; . FAPESP.
Resumo: OBJECTIVES: This study sought to analyze the extent of motor adaptation in ankle plantar flexors and dorsiflexors among older drivers during clinical isokinetic testing. METHODS: One hundred older adults (70.4±5.7 years) participated in two bilateral ankle plantar flexor and dorsiflexor isokinetic assessments at 30°/sec. Peak torque (PTQ), PTQ adjusted for body weight (PTQ/BW), and total work (TW) were analyzed. RESULTS: On the dominant side, PTQ/BW and TW were significantly greater for the second plantar flexion test than were those for the first such test (p<0.001), whereas PTQ, PTQ/BW, and TW (p<0.001) were significantly greater for the second dorsiflexion test than were those for the first such test. On the non-dominant side, plantar flexion PTQ and TW were significantly lower for the second test than were those for the first test (p<0.001). CONCLUSION: Older drivers demonstrated better performance with the dominant limb on the second test. The low variability in test execution showed the existence of a motor adaptation effect for the tested movements, despite the short recovery period between the assessments.
