RESUMO
El cáncer de pulmón es la principal causa de muerte en el mundo por cáncer, y en Colombia es la segunda. Su pronóstico es pobre cuando se ha documentado enfermedad metastásica en el sistema nervioso central. El diagnóstico se basa en el resultado definitivo de patología. Aunque los hallazgos imagenológicos pueden ser muy sugestivos de malignidad, hay reportes de otras enfermedades que pueden imitar cáncer, tales como infecciones o tumores benignos, los cuales pueden llevar a adoptar conductas terapéuticas inapropiadas. Las infecciones fúngicas como las producidas por Criptococcus neoformans, son capaces de generar lesiones que pueden imitar neoplasias. El objetivo de esta publicación es reportar el caso de un hombre a quien inicialmente se le sospechó un carcinoma pulmonar metastásico al sistema nervioso central, y finalmente se le diagnosticó una criptococosis diseminada posterior a su fallecimiento
Lung cancer is the leading cause of death from cancer in the world and the second in Colombia, its prognosis is bad when the diagnosis of metastatic disease in the central nervous system is documented. The diagnosis is based on the definitive pathologic result. Although the imaging findings can be highly suggestive of malignancy, there are reports of other conditions that can mimic lung cancer, such as infections or benign tumors, which can lead to inappropriate treatment. Fungal infections such as those caused by Criptococcus neoformans are capable of generating lesions that can mimic neoplasms. The objective of this article is to report the case of a man who was initially diagnosed with metastatic lung carcinoma to the central nervous system, and was finally diagnosed with disseminated cryptococcosis after his death

The acute exacerbations of COPD (AECOPD) are one of the main causes of hospitalization and morbimortality in the adult population. There are not many tools available to predict the clinical course of these patients during exacerbations. Our goal was to estimate the clinical utility of C Reactive Protein (CRP), Mean Platelet Volume (MPV), eosinophil count and neutrophil/lymphocyte ratio (NLR) as in-hospital prognostic factors in patients with AECOPD. A prospective cohort study was conducted in patients who consulted three reference hospitals in the city of Medellín for AECOPD and who required hospitalization between 2017 and 2020. A multivariate analysis was performed to estimate the effect of biomarkers in the two primary outcomes: the composite outcome of in-hospital death and/or admission to the ICU and hospital length-of-stay. A total of 610 patients with a median age of 74 years were included; 15% were admitted to the ICU and 3.9% died in the hospital. In the multivariate analysis adjusted for confounding variables, the only marker significantly associated with the risk of dying or being admitted to the ICU was the NLR > 5 (OR: 3; CI95%: 1.5; 6). Similarly, the NLR > 5 was also associated to a lower probability of being discharged alive from the institution (SHR: 0.73; CI95%: 0.57; 0.94) and, therefore, a longer hospital stay. It was found that a neutrophil/lymphocyte ratio greater than 5 is a strong predictor of mortality or ICU admissions and a longer hospital stay in patients hospitalized with AECOPD.
