A safe protocol to identify low-risk patients with COVID-19 pneumonia for outpatient management.

The coronavirus disease 2019 (COVID-19) outbreak has made it necessary to rationalize health-care resources, but there is little published data at this moment regarding ambulatory management of patients with COVID-19 pneumonia. The objective of the study is to evaluate the performance of a protocol for ambulatory management of patients with COVID-19 pneumonia regarding readmissions, admission into the Intensive Care Unit (ICU) and deaths. Also, to identify unfavorable prognostic factors that increase the risk of readmission. This is a prospective cohort study of patients with COVID-19 pneumonia discharged from the emergency ward of Infanta Cristina Hospital (Madrid, Spain) that met the criteria of the hospital protocol for outpatient management. We describe outcomes of those patients and compare those who needed readmission versus those who did not. We use logistic regression to explore factors associated with readmissions. A total of 314 patients were included, of which 20 (6.4%) needed readmission, and none needed ICU admission nor died. At least one comorbidity was present in 29.9% of patients. Hypertension, leukopenia, lymphocytopenia, increased lactate dehydrogenase (LDH) and increased aminotransferases were all associated with a higher risk of readmission. A clinical course of 10 days or longer, and an absolute eosinophil count over 200/µL were associated with a lower risk. After the multivariate analysis, only hypertension (OR 4.99, CI 1.54-16.02), temperature over 38 °C in the emergency ward (OR 9.03, CI 1.89-45.77), leukopenia (OR 4.92, CI 1.42-17.11) and increased LDH (OR 6.62, CI 2.82-19.26) remained significantly associated with readmission. Outpatient management of patients with low-risk COVID-19 pneumonia is safe, if adequately selected. The protocol presented here has allowed avoiding 30% of the admissions for COVID-19 pneumonia in our hospital, with a very low readmission rate and no mortality.

Intracystic papillary breast carcinoma with areas of infiltration : Report on two cases.

Intracystic papillary carcinoma of the breast associated with areas of infiltration is rare in that it constitutes less than 1% of breast cancers. After initial radiological study, these tumors show lesions with little likelihood of malignancy in a high proportion of cases. Two cases of intracystic papillary carcinoma associated with infiltration were diagnosed at the Breast Unit of Hospital Infanta Cristina. In both cases, the reason for consultation arose after palpation of a nodule and the initial radiographic analyses showed lesions with little likelihood of malignancy.

El carcinoma papilar intraquístico de mama asociado a áreas de infiltración, es una entidad infrecuente, que constituye menos de un 1% de los cánceres de mama. Se trata un tumor cuyo estudio radiológico inicial muestra lesiones con baja sospecha de malignidad en una proporción elevada de casos. Presentamos dos casos de carcinoma papilar intraquístico, asociados a infiltración diagnosticados en la Unidad de Mama del Hospital Universitario Infanta Cristina. En ambos casos el motivo de consulta fue la palpación de un nódulo y la aproximación radiológica inicial mostró lesiones con baja sospecha de malignidad.
