[Sickle cell disease – clinical manifestations and diagnostics].

Sickle cell disease is a group of diseases presenting with a set of characteristic acute and chronic manifestations. Sickle cell disease has traditionally been uncommon in the Northern European population; however, due to demographic changes, it is increasingly also something that Norwegian clinicians should be cognisant of. In this clinical review article we wish to present a brief introduction to sickle cell disease, with an emphasis on its aetiology, pathophysiology, clinical manifestation and how the diagnosis is established based on laboratory testing.

Additional value of red blood cell parameters in predicting uncommon α-thalassemia; experience from 10 years of α-globin gene sequencing and copy number variation analysis.

Introduction: The diagnosis of rare forms of α-thalassemia requires laborious genetic analyses. Accurate sample selection for such evaluation is therefore essential. The main objectives of this study were to investigate the predictive power of red blood cell parameters to detect rare forms of α-thalassemia (substudy 1), and to explore the frequency of rare versus common forms of α-thalassemia in our sample population (substudy 2).

Exploring cardiac effects after oxytocin 2.5 IU or carbetocin 100 μg: A randomised controlled trial in women undergoing planned caesarean delivery.

Background: Oxytocin can stimulate release of myocardial biomarkers troponin I and T, prolong QTc and induce ST-depression.

Objective: To explore cardiac changes after either intravenous carbetocin or oxytocin.

Study Design: Exploratory phase 4 randomised controlled trial.

Neutrophil Gelatinase-Associated Lipocalin (NGAL) and cystatin C are early biomarkers of acute kidney injury associated with cardiac surgery.

Acute kidney injury (AKI) is a serious complication in as much as half of the patients undergoing cardiac surgery, and early diagnosis and treatment are of the utmost importance. There is a need for robust biomarkers that can detect cardiac surgery-associated AKI (CSA-AKI) prior to rise in plasma creatinine, which typically occurs at least 48 h postoperatively. We compared pre- and 4, 12 and 48 h postoperative plasma (P) neutrophil gelatinase-associated lipocalin (NGAL), cystatin C, urea and creatinine, and urine (U) NGAL, as markers of AKI, in 49 patients (67% men, median age 65 years) scheduled for elective cardiac surgery (e.
