Introduction: According to figures from GLOBOCAN 2020, tumors of the central nervous system have an incidence of 1.6% with a mortality of 2.5%. For Colombia, 1,901 new cases were registered, with an incidence of 1.7% and 1,650 deaths, with a mortality of 3%. Aim: To describe the epidemiological characteristics of patients diagnosed with primary tumors of the central nervous system at a central military hospital in the period between 2008-2019. Materials and methods: A cross-sectional descriptive study was proposed, collecting data from the period between 2008 and 2019. 177 cases met these criteria, of which the sociodemographic variables were estimated, and the survival for these was determined through the Kaplan-Meyer analysis of the tumors. Results: The average 5-year survival for men is 22% and for women 27%. 18.6% of the 177 patients diagnosed with primary brain tumors in the study died after histopathological diagnosis, of which 60.6% were men and 39.4% women. Conclusions: The highlighted sociodemographic aspects represent a contribution to the generation of new evidence for primary tumors of the central nervous system in our country.

Introduction: Chronic pain and mental health disorders are common in the general population, prevalence of chronic pain ranges from 2% to 40%, and the prevalence of mental health disorders ranges from 17% to 29%. Chronic pain is associated with irritability, depression, anxiety and sleep problems such as insomnia. However, the appearance of anxiety and depression has been described as a consequence of chronic pain. Aims: To determine the sociodemographic characteristics and the association between pain syndromes and mood disorders in individuals treated in primary care. Materials and methods: A prospective cohort study was undertaken in a primary care medical center for four months with patients whose pain was the reason for consultation. Scales such as DN4, VAS, Beck's criteria, and DSM-V were applied, and the sociodemographic characteristics of these individuals were determined. Results: A total of 132 patients who met the inclusion criteria were recruited. Of these, 81.81% (108) were women, 18.18% were men (24). The mean age for both sexes was 37.9 and the mean duration in hours of each painful episode was 14.35 hours. The proportion of the disorders that was noted were as follows: insomnia in 0.303, anxiety 0.265, depression 0.090. Those who presented with anxiety or depression and another disorder was 0.053. Patients who did not develop any of the diseases of interest in this study 0.185. Discussion: The coexistence and overlap of mood disorders and insomnia in patients suffering from pain syndromes, which have little or no importance when assessing patients in primary health care centers, are under-diagnosed. However, broadening the clinical history, and correctly using diagnostic tools for mood disorders increases their diagnosis rate, ignoring the positive relationship that exists between these disorders. Conclusions: Pain disorders trigger neuropsychiatric complications. Depression, anxiety, and insomnia worsen episodes of pain. However, the correct diagnostic approach and the application of adequate management greatly reduce the complications of these types of disorders.
