ABSTRACT
INTRODUCTION: Acute respiratory infections are one of the main causes of morbidity and mortality in older adults and patients with chronic diseases. Among the responsible etiological agents are human respiratory viruses, such as: respiratory syncytial virus, parainfluenza virus and metapneumovirus. OBJECTIVE: To carry out a differential diagnostic study of respiratory viruses circulating and co-circulating in an adult population. METHODS: A pilot study was conducted in patients older than 18 years, who presented signs and symptoms suggestive of acute respiratory infection and whose clinical picture did not exceed 15 days of evolution; end-point polymerase chain reaction assays were performed with the use of specific oligonucleotides for molecular diagnosis. RESULTS: 72 specimens of patients with an age of 51.33 ± 19.33 years, with a predominance of females (4.5:1); original inhabitants of Mexico City; only 22 were positive for respiratory viruses, being mostly metapneumovirus infections. CONCLUSIONS: The knowledge of the circulating viral strains in the population will allow to determine changes that can declare an epidemiological alert leading to the best decision making for the benefit of the patients.

INTRODUCCIÓN: Las infecciones respiratorias agudas son una de las principales causas de morbimortalidad en adultos mayores y pacientes con enfermedades crónicas. Dentro de los agentes etiológicos responsables se encuentran los virus respiratorios humanos, tales como: virus sincitial respiratorio, virus parainfluenza y metapneumovirus. OBJETIVO: Realizar un estudio de diagnóstico diferencial de virus respiratorios que circulan y cocirculan en una población adulta. MÉTODO: Se realizó un estudio tipo piloto en pacientes mayores de 18 años, que presentaron signos y síntomas sugestivos de infección respiratoria aguda y cuyo cuadro clínico no sobrepasara los 15 días de evolución; se realizaron ensayos de reacción en cadena de la polimerasa de punto final con el uso de oligonucleótidos específicos para el diagnóstico molecular. RESULTADOS: Se tipificaron 72 especímenes de pacientes con una edad de 51.33 ± 19.33 años, con predominio del sexo femenino (4.5:1); originarios en su totalidad de la Ciudad de México; solo 22 fueron positivos para virus respiratorios, siendo en su mayoría infecciones por metapneumovirus. CONCLUSIONES: El conocimiento de las cepas virales circulantes en la población permitirá determinar cambios que puedan declarar una alerta epidemiológica llevando a la mejor toma de decisiones en beneficio de los pacientes.

Incoercible or intractable pain is defined as pain that is refractory to pharmacological treatment to such an extent that opioid and analgesic adverse effects outweigh the therapeutic effects. The anterior cingulate cortex (ACC) is involved in the perception of pain, especially emotional pain, so it is logical that cingulotomy has an effective therapeutic effect. Therefore, we evaluated the effectiveness of cingulotomy for the treatment of incoercible pain. An observational, longitudinal, retrospective, and analytical study was carried out on a series of cases in which bilateral cingulotomy was performed for incoercible pain, and follow-up was performed 6 months after neurosurgery in the outpatient clinic at the Neurotraumatology Clinic. A positive correlation was observed between pain intensity and medication use, indicating that an increase in pain was associated with a greater requirement for analgesics. The result was a significant reduction in pain, as measured by the visual analog scale of pain, and decreased drug use after cingulotomy. We concluded that cingulotomy reduces incoercible pain and the need for medication.
