Exploring the Effectiveness of External Use of Bach Flower Remedies on Carpal Tunnel Syndrome: A Pilot Study.

BACKGROUND: A randomized, pilot, placebo-controlled clinical trial was conducted with the aim of evaluating the effectiveness of a cream based on Bach flower remedies (BFR) on symptoms and signs of carpal tunnel syndrome. METHODS: Forty-three patients with mild to moderate carpal tunnel syndrome during their "waiting" time for surgical option were randomized into 3 parallel groups: Placebo (n = 14), blinded BFR (n = 16), and nonblinded BFR (n = 13). These groups were treated during 21 days with topical placebo or a cream based on BFR. RESULTS: Significant improvements were observed on self-reported symptom severity and pain intensity favorable to BFR groups with large effect sizes (η2partial > 0.40). In addition, all signs observed during the clinical exam showed significant improvements among the groups as well as symptoms of pain, night pain, and tingling, also with large effect sizes (φ > 0.5). Finally, there were significant differences between the blinded and nonblinded BFR groups for signs and pain registered in clinical exam but not in self-reports. CONCLUSION: The proposed BFR cream could be an effective intervention in the management of mild and moderate carpal tunnel syndrome, reducing the severity symptoms and providing pain relief.

Eating Behaviors in Cuban Adults: Results from an Exploratory Transcultural Study.

This study aims to investigate eating behaviors in Cuban adults and compare them with those of a developed Western country, Italy. The study also aimed to determine the overall accuracy of a predictive model intended to define variables which could be used to discriminate between nationalities. Participants were 283 normal weight individuals from Cuba (n = 158) and Italy (n = 125). Italians had higher scores for restrained eating on the questionnaire than Cubans with a considerable effect size. This trend was also found for emotional eating and binge eating, as well as number of current dieters, despite the fact that effect sizes were small. On the other hand, Cubans, when compared to Italians reported higher scores for food thought suppression with reward responsiveness and restrained eating emerging as significant predictors of between-country differences. To conclude, eating behaviors in Cubans could be different from those reported in European countries, perhaps as a consequence of Cuba's recent history.

Placebo: la ®mancha¼ más brillante de la Medicina / Placebo: the brightest ®spot¼ in medicine

Introducción: quizás ningún otro término haya sido tan indebidamente utilizado y causado tanta confusión como ®placebo¼. Sus efectos han potenciado los tratamientos médicos en la historia sin el debido reconocimiento. Entendido como eventos atribuibles al significado que adquiere una intervención dentro de un contexto terapéutico dado, se redimensiona y aleja de las definiciones tautológicas dominantes. Objetivo: analizar los retos que esta postura teórica plantea, así como sus potencialidades para la investigación y la práctica clínica. Métodos: Se analizan las limitaciones de su uso en Ensayos Clínicos Aleatorizados, entre las que se destaca la paradoja de la eficacia. Se contrasta la evidencia sobre su efectividad, generada en distintos contextos. Se describen los placebos disponibles en la práctica clínica y situaciones de uso; así como las opiniones de médicos y pacientes. Se introduce su efecto desde la dimensión biopsicosocial, dentro de la Medicina del Estilo de Vida. Se esbozan razones que impiden a las medicinas alternativas ®ser mejor que un placebo¼. Por último, se identifica y ejemplifica su espacio dentro la práctica clínica. Conclusiones: el efecto del placebo debe ser comprendido como un efecto del contexto, estructurado sobre la base del significado individual asignado a la intervención dentro de una cultura e historia específicas, que resulta significativo sobre numerosas enfermedades, mediante la activación y modificación variables psicológicas y fisiológicas. Concebido como Ambiente Curativo Óptimo, adquiere el ®principio activo¼ necesario para actuar por sí mismo (cuando la alternativa es no hacer nada), o potenciando el efecto de los tratamientos convencionales(AU)

Introduction: no term has probably been as misused and has caused so much confusion as the term `placebo'. Its effects have strengthened medical treatments throughout history without receiving due recognition. Understood as events attributable to the significance acquired by an intervention in a given therapeutic context, it takes on a new dimension, detaching from the prevailing tautological definitions. Objective: analyze the challenges posed by this theoretical stand, as well as its potential for research and clinical practice. Method: an analysis is conducted of the limitations of its use in randomized clinical trials, among them the efficacyparadox. A contrast is made of evidence of its effectiveness generated in various contexts. A description is provided of placebos available in clinical practice and situations of use, as well as doctors' and patients' opinions. Its effect is presented from a biopsychosocial perspective, within the framework of Lifestyle Medicine. An outline is provided of the factors preventing alternative medicines from being ®better than a placebo¼. Finally, its place in clinical practice is identified and exemplified. Conclusions: the placebo effect should be understood as an effect from the context, structured on the basis of the individual significance assigned to the intervention by a specific culture and historical development, which is significant for a large number of diseases, through the activation and modification of psychological and physiological variables. Conceived of as an Optimal Healing Environment, it acquires the ®active principle¼ required to act by itself (when the alternative is doing nothing), or strengthen the effect of conventional treatments(AU)
