Background: Diabetes mellitus is a public health problem in Mexico, and the trend of the disease is increasing. From 2000 to 2017, 7.32 million new cases were diagnosed, with pulmonary mycoses being one of the most serious complications., Aims: To describe the frequency and the clinical characteristics of patients diagnosed with pulmonary mycoses, and to identify the risk factors associated with this entity., Methods: Case-control study, paired by gender (1:1-3) and age (± 5 years), that analyzed patients with pulmonary mycosis (mucormycosis, histoplasmosis, coccidioidomycosis, blastomycosis, aspergillosis, cryptococcosis, paracoccidioidomycosis) and studied the risk factors present in each patient., Results: From the 162 patients studied, 56 suffered pulmonary mycosis and 106 were controls. The median of the age was 51 and 50 years for the cases and for the controls, respectively. Multiple logistic regression analysis showed that patients with diabetes mellitus had an odds ratio of 8,3 (p < 0.001), and patients with a history of tuberculosis had an odds ratio of 8,8 (p < 0.001)., Conclusions: Our results show that 52% of the patients with pulmonary mycoses had a history of diabetes mellitus. Diabetes mellitus is a relevant risk factor for pulmonary mycoses, which are usually diagnosed in advanced stages and have a high mortality., (Copyright © 2020 Asociación Española de Micología.

Background: Pulmonary mucormycosis is a rare opportunistic infection with high mortality that is caused by species of Mucorales. The most common species involved are Rhizopus, Mucor, Lichtheimia, and Rhizomucor., Case Report: A 56 year-old woman presented with a clinical history of diabetes mellitus type 2 and chronic renal disease. She underwent a cadaveric kidney transplantation two years before her admission, for which immunomodulating therapy with thymoglobulin, tacrolimus, mofetil-microphenolate and prednisone was established. The patient suffered a pneumonic process with cough, expectoration, and dyspnoea. The computed tomography scan showed a cavitation in the right upper lobe. With all these findings an invasive broncopulmonary aspergillosis was suspected and the patient began an antifungal treatment with voriconazole without improvement. Rhizomucor pusillus was isolated from a clinical specimen obtained by fine needle aspiration, and its identification was confirmed by PCR. After this finding amphotericin B was administered, but the patient had an uncontrolled haemoptysis and died., Conclusions: Pulmonary mucormycosis is a rare infection, usually fatal in kidney transplant recipients with anti-rejection therapy. Mucorales species usually produce thrombotic phenomena, associated with necrosis and parenchymal destruction that caused a fatal uncontrolled haemoptysis in our patient. Early diagnosis is important in order to perform any surgical treatment and to administer amphotericin B., (Copyright © 2017 Asociación Española de Micología. Publicado por Elsevier España, S.L.U.

Objective: To compare the results of quality monitoring after the implementation of improvement strategies in the respiratory intensive care unit (RICU)., Design: A prospective, comparative, longitudinal and interventional study was carried out., Setting: The RICU of Hospital General de México (Mexico)., Patients: All patients admitted to the RICU from March 2012 to March 2013., Interventions: An evidence-based bundle of interventions was implemented in order to reduce the ratios of three quality indicators: non-planned extubation (NPE), reintubation, and ventilator-associated pneumonia (VAP)., Variables of Interest: NPE, reintubation and VAP ratios., Results: A total of 232 patients were admitted, with a mean age of 49.5±17.8years; 119 (50.5%) were woman. The mean Simplified Acute Physiology Score (SAPS-3) was 49.8±17, and the mean Sequential Organ Failure Assessment (SOFA) score was 5.3±4.1. The mortality rate in the RICU was 38.7%. The standardized mortality ratio was 1.50 (95%CI: 1.20-1.84). An improved ratio was observed for reintubation and NPE indicators compared to the ratios of the previous 2011 cohort: 1.6% vs. 7% (P=.02) and 8.1 vs. 17 episodes per 1000 days of mechanical ventilation (P=.04), respectively. A worsened VAP ratio was observed: 18.4 vs. 15.1 episodes per 1000 days of mechanical ventilation (P=.5)., Conclusions: Quality improvement is feasible with the identification of areas of opportunity and the implementation of strategies. Nevertheless, the implementation of a bundle of preventive measures in itself does not guarantee improvements., (Copyright © 2013 Elsevier España, S.L.U. and SEMICYUC. All rights reserved.)
