16 May 2017 (Tuesday) - Grey Platelet Syndrome

The Lablogatory people sent me an email about a case study today. A twelve year old girl presented with thrombocytopenia. Previous platelet counts performed at a different facility showed a similarly reduced platelet count. The patient had a history of bruising and intermittent epistaxis.

It was a good case study about Gray Platelet Syndrome…

Higher Hematocrit Levels Are Associated with Increased Thrombosis Risk and Reduced Bleeding

May 10, 2017
A growing number of recent studies have observed an association between elevated hematocrit levels and thrombosis. However, the mechanism behind this pathway has remained elusive. A recent study induced an elevation of hematocrit levels in otherwise healthy mice to tease apart the etiology of the thrombosis formation under increased RBC levels. Compared with control mice [Read More]

Early Administration of Tranexamic Acid Reduces Maternal Deaths Due to Bleeding

May 3, 2017
Administration of tranexamic acid, an antifibrinolytic drug, has been shown to reduce bleeding in trauma and surgery patients. The results of the WOMAN (World Maternal Antifibrinolytic) trial recently published in The Lancet show that tranexamic acid also reduces the risk of maternal death due to bleeding. Between 2010 and 2016, over 20,000 women with post-partum [Read More]

Transfusion of Red Blood Cells from Younger Donors Is Not Associated with Improved Survival

April 26, 2017
Animal models suggest that blood from younger donors may provide revitalizing benefits, but findings from observational cohort studies on this topic have been inconsistent. Investigators in Scandinavia recently performed a retrospective cohort study following 968,264 red blood cell (RBC) transfusion recipients for 10 years. Since multiple transfusions can confound results, researchers used multiple approaches to [Read More]

Clinical Commentaries

12 May 2017 (Friday) - Case Study

This case appeared on Facebook this morning. “Question is Cll or Prolymphocytic leukemia?? Any ideas”.
At the risk of appearing sarcastic my first idea was to improve the English…

Reading the comments there were as many opinions as there were people to offer them. For myself it has been my experience that automated analysers are good at identifying lymphoid cells. However this device has found a monocyte count of 50 x 109 cells /l (converting units to what I am used to!). Those would be myeloid cells. Several people had said flow cytometry would be useful here. I’d have to agree…

10 May 2017 (Wednesday) - Safety Officer ?

The Lablogatory people sent me an email today. They’d blogged about the role of the safety officer. Not a role I’d like to do (again) but thought-provoking nonetheless…
