ABSTRACT
Breast metastases from neuroendocrine neoplasms (NENs) are considered infrequent. We report a case of a patient with ileocecal neuroendocrine tumor (NET) metastases to both breasts, for whom the initial clinical presentation was chronic diarrhea. Breast metastasis was initially suspected by a 68-Gallium DOTANOC positron emission tomography (PET)/CT and was confirmed by histopathology. We also performed a literature review in which we identified 116 cases of NENs metastatic to the breast reported so far. Most cases occurred in older women, were caused by NETs, and had the gastrointestinal tract as the primary site.
ABSTRACT
RESUMEN Objetivo Caracterizar la población afectada por tuberculosis multidrogorresistente y resistente a rifampicina (TB-MDR/RR) en Colombia. Métodos Estudio transversal a partir de la información nominal de los pacientes con TB-MDR/RR tratados y reportados en Colombia desde 2009 hasta 2020, usando la totalidad de las fuentes de información oficiales. Se compararon, además, las tasas de TB-MDR/RR de diferentes grupos de riesgo con la de la población general y se evaluaron variables asociadas a la TB-MDR/RR extrapulmonar y a resistencias medicamentosas. Resultados La TB-MDR/RR ha aumentado progresivamente durante la última década y se ha concentrado en hombres (64% vs. 36%, p<0,001), edades medias (mediana: 39,5 años; RIC: 27) y zonas de mayor densidad poblacional (59% de los casos en Antioquia, Valle del Cauca y Santiago de Cali). Además, al compararlas con las poblaciones de referencia que aplicaran, se evidenciaron tasas 2, 10 y 200 veces mayores en población indígena (9,45/1 000 000 vs. 4,31/1 000 000; p=0,02), prisioneros (169/1 000 000 vs. 16,9/1 000 000; p<0,001) y habitantes de calle (21/100000 vs. 0,1/100 000; p<0,001), respectivamente. Conclusiones El aumento en los casos de TB-MDR/RR y sus grupos de riesgo deben tenerse en cuenta para la planeación de políticas, distribución de recursos y atención clínica.
ABSTRACT Objective To describe the population affected by rifampin-resistant/multidrug-resistant tuberculosis (RR/MDR-TB) in Colombia. Methods Cross-sectional study on all the patients treated for RR/MDR-TB in Colombia between 2009 and 2020, using all the official sources of information. In addition, a comparison was made between the rates of RR/MDR-TB in some higher-risk groups and average population. Finally, the variables associated to pulmonary versus extrapulmonary RR/MDR-TB and those associated to resistance to other drugs were evaluated. Results RR/MDR-TB cases have progressively increased during the last decade. These cases were concentrated in men (64% vs. 36%, p<0.001), middle aged adults (median: 39.5 years old; IQR: 27), and in geographic regions with higher population density (59% of cases in Antioquia, Valle del Cauca and Santiago de Cali). Also, the rate of RR/MDR-TB was 2, 10 and 200 times higher in indigenous (9.45/1 000 000 vs. 4.31/1 000 000; p=0.02), prisoners (169/1 000 000 vs. 16.9/1 000 000; p<0.001), and homeless population (21/100 000 vs. 0.1/100 000; p<0.001), respectively. Conclusions The increase in RR/MDR-TB cases and their concentration in higher-risk groups must be kept in mind to make better policies, a more efficient distribution of resources, and better patient care.
