Objective: To describe the underlying pathophysiologic mechanisms of the effect of corticosteroids in a patient with late septic shock.
Design: Case report.
Setting: The medical intensive care unit at University Medical Center Utrecht.
Patient: An 86-yr-old female patient with late septic shock requiring mechanical ventilation and vasopressive agents.
Interventions: Administration of hydrocortisone, 300 mg daily.
Measurements And Main Results: Within 3 days of corticosteroid treatment, the patient could be weaned of vasopressive agents and mechanical ventilation. Serum C-reactive protein levels normalized. Nuclear factor-kappaB activation in unstimulated and in vitro lipopolysaccharide-stimulated peripheral blood mononuclear cells decreased to background level within 5 days. Repeated functional tests of the hypothalamic-pituitary-adrenal axis were normal.
Conclusion: Our data suggest that the pathophysiologic mechanism behind the clinical effects of supraphysiologic doses of corticosteroids in late septic shock is directly related to the inhibition of nuclear factor-kappaB in peripheral blood mononuclear cells.

Introduction: Sepsis-associated encephalopathy (SAE) is one of the most common complications seen both in early and late stages of sepsis, with a wide spectrum of clinical manifestations ranging from mild neurological dysfunction to delirium and coma. The pathophysiology of SAE is still not completely understood, and the diagnosis can be challenging especially in early stages of sepsis and in patients with subtle symptoms.
Aim Of The Study: The objective of this study was to assess the coagulation profile in patients with early SAE and to compare the hemostatic parameters between septic patients with and without SAE in the first 24 hours from sepsis diagnosis.

Introduction: During revision surgery for the management of patients presenting with long-bone upper extremity nonunion, it is crucial to rule out fracture-related infection (FRI). This is especially true if there are clinical signs suggestive of FRI, or if there is a history of prior FRI, open wound fracture, or surgery. This study aimed to determine the efficacy of frozen section analysis (FSA) in providing real-time diagnosis of FRI in patients with upper-limb long-bone nonunion undergoing revision surgery.

Introduction: Sepsis is an uncontrolled systemic response to infection that leads to life-threatening organ dysfunction. The in-hospital mortality rate remains significantly high in septic shock patients with malignancies. This study investigates whether early and high-volume administration of sodium bicarbonate during continuous renal replacement therapy (CRRT) can reduce 28-day mortality, increase shock reversal rates, and shorten the duration of CRRT, mechanical ventilation, and intensive care unit (ICU) stays.
