ABSTRACT
BACKGROUND: Although tumors of the central nervous system (CNS) are rare, they can cause significant morbidity and mortality. The clinical presentation of patients with non-functional pituitary adenomas (NFPA) ranges from being completely asymptomatic to causing pituitary, hypothalamic, or visual dysfunction due to their large size. Patients usually arrive with large tumors at the time of diagnosis. Objectives: Try to describe the characteristics of NFPA and explain the causes of delayed diagnosis. Methods: We carried out a retrospective study including 58 patients with NFPA and analyzed the tumor volume at the time of diagnosis and its relationship with sociodemographic and health sector variables. Results: Low socioeconomic status (SES) was associated with high tumor volume (SES 1-2 of 17.4 cm3 vs 3-6 of 11.7 cm3, p=0.018), and the time between first consultation and diagnosis was longer in the public sector than in the private sector (13.5 months vs 5.1 months). The time between the first symptom and the first consultation was shorter when they had visual impairment than when they did not (4.1 vs 18.4 months, p=0.006). CONCLUSIONS: On the one hand, citizens should be made aware that a visual deficit should make them go to a medical check-up, and on the other hand, strengthen the health system so that they have the NFPA as a differential diagnosis in patients with some visual alteration. Socioeconomic inequality in our country undoubtedly puts the underprivileged at greater risk.
ABSTRACT
Background: Parkinson's disease is poorly studied in Colombia. It is pharmacologically managed, but for refractory cases, surgery is a therapeutic option, positively impacting on quality of life. Objective: To determine the impact of deep brain stimulation as management in the control of progression in patients with Parkinson's disease attended our institution between the years 2014 to 2020. Method: Descriptive retrospective study, with patients collected between 2014 and 2020 undergoing deep brain stimulation surgery. The MDS-UPDRS (Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale) was applied in the pre- and postoperative period, and the results were compared. Results: 21 patients were included and the UPDRS was applied, finding a decrease in scores in the postoperative period. One patient had an operative site infection. Conclusions: There was an improvement in the MDS-UPDRS score, with a low rate of complications. The procedure time was prolonged from the preoperative evaluation. Deep brain stimulation is the management of choice for refractory Parkinson's disease. The patients in this series showed improvement in their symptoms. Unfortunately, there are limitations to perform this procedure in Colombia, such as the delay in the authorization of the procedure.
Antecedentes: La enfermedad de Parkinson está poco estudiada en Colombia. Es de manejo farmacológico, pero para casos refractarios la cirugía es una opción terapéutica que impacta positivamente en la calidad de vida. Objetivo: Determinar el impacto de la estimulación cerebral profunda como manejo en el control de la progresión en pacientes con enfermedad de Parkinson atendidos nuestra institución entre los años 2014 a 2020. Método: Estudio descriptivo de corte retrospectivo con pacientes recolectados entre los años 2014 y 2020 sometidos a cirugía de estimulación cerebral profunda. Se aplicó la MDS-UPDRS (Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale) en el pre- y el posoperatorio, y se compararon los resultados. Resultados: Se incluyeron 21 pacientes y se les aplicó la MDS-UPDRS, encontrando una disminución en las puntuaciones en el posoperatorio. Un paciente presentó infección del sitio operatorio. Conclusiones: Hubo mejoría en la puntuación de la MDS-UPDRS, con baja tasa de complicaciones. El tiempo de realización del procedimiento fue prolongado desde la valoración preoperatoria. La estimulación cerebral profunda es el manejo de elección para la enfermedad de Parkinson refractaria. Los pacientes de esta serie mostraron mejoría en sus síntomas. Desafortunadamente, existen limitaciones para la realización de este procedimiento en Colombia, como el retraso en la autorización del procedimiento.
