Serratia marcescens outbreak in a COVID-19 intensive care unit - Are there any factors specific to COVID-19 units that facilitate bacterial cross-contamination between COVID-19 patients?

COVID-19 dedicated units were created early in the pandemic. Despite their need, factors specific to these units can possibly increase the risk of bacterial cross-contamination between COVID-19 patients. We report a Serratia marcescens outbreak in a COVID-19 intensive care unit, later discussing factors specific to COVID-19 units that may facilitate bacterial cross-contamination in such units, and raising awareness for such an issue.

Spontaneous Tumor Lysis Syndrome: A Rare Presentation in Plasmablastic Lymphoma.

Tumor lysis syndrome is an oncological emergency, which can ultimately lead to death if not recognized early and treated accordingly. The institution of adequate prophylactic measures can decrease its incidence and severity; but very rarely, a highly aggressive neoplasm such as acute lymphoblastic leukemia or Burkitt's lymphoma can present with spontaneous tumor lysis syndrome (sTLS). We present the case of a 58-year-old male with newly diagnosed plasmablastic lymphoma with a retroperitoneal bulky mass invading the bladder, who presented with severe sTLS and was admitted to an intensive care unit due to acute renal failure and hyperkalemia requiring emergent renal replacement therapy.

Cytomegalovirus Reactivation in Patients with Sepsis in an Intensive Care Unit in Portugal.

Introduction: In the last few years, cytomegalovirus reactivation has been considered an aggravating factor for septic patients in Intensive Care units. The main objectives of this study were to determine cytomegalovirus reactivation in patients with a diagnosis of sepsis admitted to an intensive care unit, and whether this reactivation was related to the evolution of the patient's clinical condition.

Material And Methods: The detection of cytomegalovirus DNA was performed by real-time polymerase chain reaction and the concentration of nine cytokines (IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL- TNF-α, and INFγ) were determined by a Multiplex ELISA technique.

Inverted Variant of Takotsubo Syndrome Caused by Inhaled Adrenergic Beta-2 agonists.

Unlabelled: Takotsubo syndrome (TS) is an acute and reversible clinical syndrome characterized by transient hypokinesis of the left ventricular (LV) apex. Variant forms of LV dysfunction have been reported, including inverted Takotsubo syndrome (ITS), which represents only 5% of cases and has previously been linked to excessive use of inhaled adrenergic beta-2 agonists. The authors describe the case of a 60-year-old female patient who was diagnosed with ITS after the excessive use of inhaled adrenergic beta-2 agonists.
