Cerebral vasoreactivity to acetazolamide is not impaired in patients with severe sepsis.

Introduction: The pathophysiology of sepsis-associated encephalopathy (SAE) is not entirely clear, but one of the possible underlying mechanisms is the alteration of the cerebral microvascular function. The aim of the present work was to test whether cerebral vasomotor reactivity is impaired in patients with severe sepsis.

Methods: Patients fulfilling the criteria of clinical sepsis and showing at least 2 organ dysfunctions were included (n = 16).

Epidemiology of acute kidney injury in Hungarian intensive care units: a multicenter, prospective, observational study.

Background: Despite the substantial progress in the quality of critical care, the incidence and mortality of acute kidney injury (AKI) continues to rise during hospital admissions. We conducted a national, multicenter, prospective, epidemiological survey to evaluate the importance of AKI in intensive care units (ICUs) in Hungary. The objectives of this study were to determine the incidence of AKI in ICU patients; to characterize the differences in aetiology, illness severity and clinical practice; and to determine the influencing factors of the development of AKI and the patients' outcomes.

[Sepsis-associated encephalopathy].

Sepsis-associated encephalopathy is a common but neglected clinical symptom of systemic inflammatory reaction in the early phase. The clinical spectrum of diffuse cerebral dysfunction induced by systemic sepsis--sepsis-associated encephalopathy according to the new terms--varies from transient, reversible encephalopathy, to severe irreversible brain damage. The aim of the present publication is to summarize the pathophysiology, frequent symptoms and possible treatments of the disease based on international and Hungarian articles on this topic.

Carotid intima-media thickness and cerebrovascular reactivity in long-term type 1 diabetes mellitus.

Purpose: Diabetes mellitus (DM) is one of the leading risk factors for cerebrovascular diseases. Both macro- and microvascular damage may occur. The aim of the present work was to assess intima-media thickness as well as cerebral vasoreactivity in patients suffering from type 1 diabetes mellitus (IDDM).
