RESUMO
Resumen: Introducción: En México, la primera clínica especializada en el alivio del dolor fue fundada en 1972 por el Dr. Ramón De Lille Fuentes en el Instituto Nacional de Ciencias Médicas y Nutrición «Salvador Zubirán¼ (INCMNSZ). Material y métodos: Se realizó una búsqueda histórica documental y entrevistas a quienes han colaborado con el Departamento de Medicina del Dolor y Paliativa del INCMNSZ desde su fundación. Resultados: Nuestra visión es ofrecer atención del dolor, cuidados paliativos y apoyo continuo. Para ello, documentamos nuestra historia y los logros del departamento. Conclusiones: A 50 años de su fundación, el Departamento de Medicina del Dolor y Paliativa del INCMNSZ es un foro de desarrollo científico y de formación de capital humano con un enfoque humanista.
Abstract: Introduction: In Mexico, the first clinic specializing in pain relief was founded in 1972 by Dr. Ramón De Lille Fuentes at the Instituto Nacional de Ciencias Médicas y Nutrición «Salvador Zubirán¼ (INCMNSZ). Material and methods: A historical documentary search and interviews were carried out with those who have collaborated with the Department of Pain and Palliative Medicine of the INCMNSZ since its foundation. Results: Our vision is to offer pain management, palliative care, and ongoing support. To do this, we document the history and achievements of the department. Conclusions: 50 years after its foundation, the INCMNSZ Department of Pain and Palliative Medicine is a forum for scientific development and human capital training with a humanistic approach.
RESUMO
Sleep disturbances frequently occur in people with whiplash-associated disorder (WAD) and have been evaluated using questionnaires or actigraphy. It is not clear whether sleep architecture, as assessed by polysomnography (PSG), is altered in individuals with WAD. Additionally, in people with WAD, muscle dysfunction is observed during tasks performed during wakefulness. Thus, this study aimed to analyze the sleep architecture of patients with chronic WAD as well as to evaluate trapezius muscle activity during sleep. Nine women with chronic WAD and nine healthy age-matched women participated in the study. Two PSG recordings were conducted for each participant. Surface electromyography signal samples of the right and left trapezius, and mentonian muscles were obtained from N2, N3, and REM sleep stages for analysis. Significant differences were found in the percentages of total sleep time in the N1 and N2 stages between the two groups. While the muscle tone of the three muscles analyzed decreased progressively across the sleep stages in the healthy group, in the chronic WAD group, this decrement was observed only in the mentonian muscle, and the trapezius muscle continued to exhibit the same muscle tone throughout the sleep stages without atonia during REM sleep. The absence of trapezius muscle atonia during REM sleep in the WAD patients may be related to dysfunction of the mechanisms that regulate motor activity.
