[Leukoerythroblastic reaction associated with COVID-19 infection. Case report].

Introduction: COVID-19 disease is an acute viral pneumonia with multiple extrapulmonary manifestations, including certain hematological alterations. The leukoerythroblastic reaction or leukoerythroblastosis is defined by the presence in peripheral blood of nucleated erythroid cells and immature myeloids. Among its most frequent causes is medullary invasion by solid tumors and hematological neoplasms, so the recognition and consequent study of this reaction is extremely important.

[Clinical and microbiological characteristics of bloodstream infections in adult neutropenic patients].

Bloodstream infections (BI) are relevant in neutropenic patients because they are associated with an increased number of complications and death. The objective was determinate the epidemiologic and microbiologic features of the BI in neutropenic patients with solid neoplasm (SN) and hematologic neoplasm (HN). Retrospective study in two third level hospitals between 2009 and 2016.

Urinary tract infections in hospitalized patients.

Introduction: Urinary Tract Infections (UTI) are an important cause of morbidity in the community, constituting one of the main reasons for hospitalization, and the fourth cause of healthcare-associated infection. The objectives of this study were to determine the frequency of community-acquired UTI (CA-UTI) with need of hospitalization and healthcare-associated UTI (HA-UTI), their risk factors, etiologic agents and their antimicrobial susceptibility spectrum.

Methods: A prospective and analytic study was conducted, in which all admissions regarding CA-UTI with need of hospitalization and HA-UTI were evaluated during the period between 2016 and 2017 in two university hospitals.

[Epidemiological and microbiological characteristics of uncomplicated urinary infections].

Introduction: Uncomplicated urinary tract infections(UC-UTI) represent a frequent reason for consultation. Most cases are empirically treated, but the antimicrobial susceptibility of the causative microorganisms has changed over the past years. The objectives of this study where to determine UC-UTI causative microorganism and their antimicrobial susceptibility profiles in adult women.

[Bloodstream infections in cancer patients].

Bloodstream infections (BI) are an important cause of morbidity and mortality in cancer patients. A retrospective study was performed in two hospitals aimed to evaluate characteristics of BI episodes occurred in adult patients with hematologic (HN) and solid (SN) neoplasia other than non-melanoma skin cancers in the period 2009-2016. A total of 467 episodes of bacteremia and 16 of fungemia were identified.
