The objective of this study was to evaluate the efficacy of age, creatinine and ejection fraction (ACEF) score and the modified ACEFCG model, incorporating creatinine clearance, to predict immediate operative mortality risk of patients undergoing elective cardiac surgery. A retrospective analysis was performed of prospectively collected data between 2012 and 2015, from a series of 1190 adult patients who underwent elective cardiac surgery. Operative risk mortality was assessed with ACEF, ACEFCG and EuroSCORE II. ⋯ For clinical use, the ACEF score seems to be adequate to predict mortality in low- and intermediate-risk patients. Though the ACEFCG score had a better discriminatory power and calibration, it tended to overestimate the expected risk. Since ideally, a simpler risk stratification score should be desirable for bedside clinical use, the ACEF model reasonably met the expected performance in our population.

Drug hypersensitivity reactions (RHD) are those that present clinically as allergic. They can or cannot involve an immunologic mechanism of lesion. They are frequent and, occasionally, life threatening. ⋯ Positive symptoms included generalized pruritus, rash, urticaria, angioedema, rhinitis, bronchospasm, nausea and anaphylaxis. All the patients with positive tests had a good response to treatment. It can therefore be concluded that drug tests undertaken on individuals with suspected drug allergy, performed by experienced personnel and in controlled settings, are useful and safe to confirm drug hypersensitivity.

Anaphylaxis during anesthesia is an unpredictable, severe, and rare reaction. It has an incidence of 1/10 000 to 1/20 000 surgeries. In most series, the responsible drugs include neuromuscular blocking agents, latex, or antibiotics. ⋯ The responsible drugs during surgery anaphylaxis were neuromuscular blocking agents, latex, patent blue, and ranitidine. Ortho-phthalaldehyde (OPA) was identified during endoscopic studies; latex was responsible in transvaginal ultrasounds; and amoxicillin in the dental procedure. The aim of the present article is to review our experience studying allergic systemic reactions and anaphylaxis during general anesthesia and medical procedures, emphasizing the severity of these reactions and the need for causative drug identification.

A surveillance study was conducted at a University Hospital in Buenos Aires City aimed to assess the rates of colonization with carbapenemase-producing strains of Klebsiella pneumoniae, which are bacteria of utmost epidemiological importance. To this end, rectal swabs collected from all inpatients were cultured for the presence of these bacteria. Two point prevalence surveys showed high prevalence rates (up to 25%). ⋯ As for the prior use of antibiotics, results were close to statistical significance but without reaching it. Measures were implemented in order to control the spread of the microorganism in the acute setting and beyond. Upon implementation of such measures, a third prevalence survey was performed that showed a decrease in the horizontal transmission of the microorganism.

Pregnancy and postpartum control in HIV infected women. We present data from a retrospective observational descriptive study with the objective of evaluating characteristics of HIV-infected pregnant women, analyze the level of control of pregnancy and assess adherence to treatment and loss of follow up after delivery. We analyzed reported data of 104 pregnancies, 32.7% of them under 25 years old. ⋯ The viral load after 32 weeks of pregnancy was available in 82.7%, being less than 1000 cop/ml in 78 (75%), less than 200 cop/ml in 70 (67.3%) and not available in 18 (17.3%) of cases. We observed a considered high rate of adherence failure and loss of follow up after delivery. Reported data should alert programs on the need to implement strategies to promote early pregnancy control and increase adherence and retention in care, especially in the postpartum period.
