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.

Sleep architecture and the absence of trapezius muscle atonia in women with chronic whiplash-associated disorder: a pilot study.

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.

New frontiers in the future of palliative care: real-world bioethical dilemmas and axiology of clinical practice.

BACKGROUND: In our time there is growing interest in developing a systematic approach to oncologic patients and end-of-life care. An important goal within this domain is to identify the values and ethical norms that guide physicians' decisions and their recourse to technological aids to preserve life. Though crucial, this objective is not easy to achieve. The purpose of this study is to evaluate empirically the real-life bioethical dilemmas with which palliative physicians are confronted when treating terminal cancer patients. METHODS: A quasi-experimental, observational, comparative, prospective and mixed (qualitative and quantitative) study was conducted in order to analyse the correlation between the palliative doctor-patient relationship and ethical judgments regarding everyday bioethical dilemmas that arise in palliative clinical practice. The values at stake in decision-making on a daily basis were also explored. From February 2012 to march 2014, palliative healthcare personnel were invited to participate in a research project on axiology of clinical practice in palliative medicine. Each participant answered to a set of survey instruments focusing on ethical dilemmas, views, and representations of clinical practice. For this analysis we selected a convenience sample of 30 physicians specialized in pain medicine and palliative care (algologists and palliativists), with two or more years of experience with oncologic patients and end-of-life care. RESULTS: 113 dilemmas were obtained, the most frequent of which were those regarding sedation, home administration of opioids, and institutional regulations. We observed that the ethical nucleus of palliative medicine is truth-telling, implying bidirectional trust between patients and healthcare providers. The two most prominent virtues among the participants in our study were justice and professional humility. The outstanding roles of the physician in palliative medicine are as educator and as adviser, followed by that of provider of medical assistance. CONCLUSIONS: This investigation opens up new horizons in a career path where professional wearing is rampant. The rediscovery of values and virtues in palliative clinical practice will renew and replenish the motivation of healthcare providers who carry out these duties, giving them a new professional and personal perspective of growth.

Practice guidelines for the management of low back pain. Consensus Group of Practice Parameters to Manage Low Back Pain.

It has been documented that pain in its diverse modalities is the most common cause of medical attention. In Mexico, an increase in its frequency has promoted its consideration in several health programs. On the other hand, inadequate pain management will cause severe physical, psychoaffective, and socioeconomic repercussions for patients, families, and public health services. Despite this panorama, there has not been an agreement to establish better diagnostic and therapeutic methods for the management of chronic pain. A consensus group was reunited and was integrated by medical experts from private and public institutions and from various states of the Mexican Republic. To assure the development of these practice guidelines, these experts had experience in the assessment and treatment of conditions causing pain. With the guidelines used by other consensus groups, meetings were held to analyze and discuss published literary evidence for the management of low back pain. The recommendations were classified according to their methodological strength. As a result of this meeting, consensus recommendations were based on evidence and operational conclusions of such proactive educational plans, institutional policies and diagnostic recommendations for pharmacological and nonpharmacological treatment in order for Mexican physicians to provide a better therapeutic approach to low back pain.
