A retrospective-observational analytical study was carried out to evaluate the epidemiology of catheter-related bloodstream infections (CRBSI) in 773 adult patients hospitalized in the intensive care unit (ICU) of the Hospital Alemán of Buenos Aires, Argentina, between 1 December 2018 and 30 June 2020. During the study period, the incidence of CRBSI was 8.7 cases per 1000 catheter days. The occurrence of CRBSI was found associated with a poor clinical evolution, as evidenced by a stay in the ICU significantly longer than the stay of patients without CRBSI (median: 21.5 days vs. 4 days, p < 0.001). ⋯ In this analysis, the risk of infection was not influenced by the anatomical site of insertion of the catheter, the ward where the procedure was performed (ICU vs. operating room/external ward), the skill of the medical practitioner, or the use of ultrasound to guide vascular accesses. We conclude that CRBSIs are a frequent complication in our department with relevant clinical consequences. Knowing the epidemiology and the problems of each service allows programming interventions aimed to correct specific public health problems.

Adrenal crisis is the most extreme presentation form of adrenal insufficiency and represents a life-threatening endocrinological emergency. This situation can be triggered by different causes including the use of CYP3A4-inducing drugs, which accelerate hydrocortisone clearance. We describe the case of an 85-year-old woman with secondary adrenal insufficiency and chronic renal disease, who presented symptoms compatible with adrenal crisis (asthenia, adynamia, severe hyponatremia associated with neurological symptoms and hypotension) nine days after the start of modafinil treatment. ⋯ After ruling out the possible triggering causes (infectious, ischemic, pulmonary thromboembolism and failure to take hydrocortisone), it was interpreted that modafinil precipitated the symptoms of adrenal insufficiency by increasing the steroid clearance. Modafinil has the ability to induce the activity of CYP3A4 and consequently decrease the bioavailability of hydrocortisone. We emphasize the need to adjust steroid dose replacement in subjects receiving metabolism-inducing drugs.

COVID-19 pneumonia represents a challenge for health systems. The objective of this study is to describe the clinical presentation and evolution of hospitalized patients with COVID-19 pneumonia. This is a prospective and descriptive study. ⋯ In-hospital mortality was 18.9% (n = 80) and 23.7% (n = 100) received mechanical ventilation. 21.9% (n = 92) presented in-hospital complications. 39.6% (n = 67) of those over 60 years of age were admitted to the Intensive Care Unit and 31.4% (n = 54) died. 76.9% (n = 319) of the patients received corticosteroids, 69.3% (n = 289) antibiotics, and convalescent plasma 10.5% (n = 43). This series stands out for the high rate of comorbidities and the severity of the patients included. Mortality was similar to other international series.

The BRAFV600E point mutation plays a key role in the tumorigenesis of many gliomas. Inhibiting its product is part of the innovative therapies emerging in recent years. Knowing the role of these treatments is essential. ⋯ Five patients had grade 3-4 toxicity, with subsequent full recovery. A good and sustained clinical-radiological response, with acceptable tolerance, is described in patients with BRAFV600E mutated low-grade gliomas treated with BRAFV600E inhibitors. In contrast, the response in patients with high-grade gliomas was intermediate and of short duration, with early tumour progression.

Observational Study
[Clinical characteristics of SARS-CoV-2 disease (COVID-19) in middle-aged patients].
Coronavirus disease 2019 (COVID-19) meant an unprecedented global crisis, which involved the reorganization of health systems and the rationalization of available diagnostic and therapeutic resources. The objective of this observational and retrospective study was to analyze the clinical characteristics and evolution of patients admitted to general ward, intensive care unit and emergency department of a high complexity hospital in Buenos Aires city, during the first seven months of viral circulation. A total of 1005 patients with laboratory-confirmed COVID-19 were included. ⋯ In-hospital mortality was 2.3%, and 20.5% among critically ill patients. A statistically significant association was found between mortality and age, with an age difference of 9.6 years, being greater among the deceased (p = 0.0004; 95% CI 4-14). However, there was no association between the presence of comorbidities and sex vs. mortality and severity of the disease.
