ABSTRACT
Introducción: la luxación de la articulación temporomandibular es un desplazamiento del cóndilo fuera de sus posiciones funcionales dentro de la fosa articular y la eminencia articular, la cual ocasiona una pérdida completa de la función articular. La luxación crónica es toda luxación aguda que progresa sin un tratamiento específico y que puede ser de carácter recurrente. La eminectomía es un tratamiento quirúrgico definitivo contra la luxación crónica de articulación temporomandibular. Objetivo: reportar el caso clínico de un paciente masculino, de la tercera década de su vida, con diagnóstico de luxación crónica de la articulación temporomandibular de cinco meses de evolución y presentar una revisión actualizada de la literatura sobre este procedimiento quirúrgico. Caso clínico: el paciente fue tratado quirúrgicamente con eminectomía bilateral. Discusión: la eminectomía es un procedimiento quirúrgico controversial; sin embargo, recientes investigaciones lo catalogan como seguro y efectivo. Conclusión: el caso clínico presentado muestra un buen resultado.
Background: Temporo-mandibular joint dislocation is a displacement of the condyle, out of its functional positions within the articular fossa and articular eminence, causing a complete loss of joint function. Chronic dislocation is any acute dislocation that progresses without specific treatment and that can be recurrent. Eminectomy is a definitive surgical treatment for chronic temporomandibular joint dislocation. Objective: To report the clinical case of a male patient in the third decade of his life with a diagnosis of chronic dislocation of the temporomandibular joint of 5 months of evolution and to carry out an updated review of the literature on this surgical procedure. Case Report: The patient was treated surgically with bilateral eminectomy. Discussion: Eminectomy is a controversial surgical procedure; recent research classifies it as safe and effective. Conclusion: The presented clinical case shows a good result.

The opioid crisis is a growing social and public health phenomenon, particularly in developed countries such as the United States. Since the 1990s, this crisis has shown a variety of causal processes and consequences and has affected quality of life for millions of individuals, families, and communities across the globe. Although abuse of opioid-based painkillers appears to have triggered the epidemic in the United States, in this article, the problem is examined with a focus on Latin America, where drug-associated problems constitute threats to the health and quality of life for large segments of the population. After a review of the history of opium consumption and its consequences in the world and in Latin America, the authors present epidemiological data and information about regional market differences, professional involvement, clinical practices, public health realities, and prevention efforts. Recommendations are made for collaborative efforts to promote prevention policies and measures to improve the situation.
ABSTRACT
OBJECTIVE: To assess the autonomic nervous system (ANS) in coma by heart rate variability (HRV). METHODS: Sixteen comatose patients and 22 normal subjects with comparable ages and genders were studied. Patients were classified in two subgroups according to the Glasgow Coma Scale (GCS). Time, frequency, and informational HRV domain indices were calculated. RESULTS: A notable reduction of HRV was found in patients. Regarding the time domain indices, the triangular index, and the Delta_RRs, were significantly reduced in the subgroup with GCS=3. Absolute power for the whole frequency spectrum decreased whenever GCS scores were lower. A significant decrement was found for absolute power of the VLF and LF bands in the subgroup of GCS=3, and although it was lower for the HF band in these patients, those changes were not statistically significantly different. The LF/HF ratio and the Shannon´s entropy indices were significantly reduced in the subgroup with GCS=3. Our results are discussed regarding the progressive dysfunction the ANS networks when coma deepens. CONCLUSIONS: The HRV procedure is a powerful tool to assess the ANS in comatose patients. SIGNIFICANCE: HRV is a minimally invasive, low-cost methodology, suitable for assessing the ANS in coma.
