Thrombocytopenia is usually acquired. The laboratory artefact of pseudothrombocytopenia should always be excluded. Bone marrow insufficiency with impaired platelet production results from infiltrating tumor cells or from a myelodsplastic syndrome. In patients with splenomegaly, platelets are trapped by the spleen. An increased platelet turnover is caused by activation of the clotting cascade, e.g....

In the hemodialysis patient population, a surgically created arteriovenous fistula is the preferred vascular access option. Development of high-output heart failure may be an underappreciated complication in patients who have undergone this procedure. When a large proportion of arterial blood is shunted from the left-sided circulation to the right-sided circulation via the fistula, the increase in...

A high anion gap in diabetic ketoacidosis (DKA) suggests that some unmeasured anions must contribute to the generation of the anion gap. We investigated the contribution of D-lactate to the anion gap in DKA.

Imaging of perfusion using ultrasound.

Added: 06:00 EDT 20 Jul 2010

Ultrasound can be used to image perfusion in two ways: the traditional one using Doppler and the more recent using microbubble contrast agents. Doppler is simple to use and inexpensive but is limited to larger vessels with faster flow rates. It cannot interrogate the microvasculature because bulk tissue movement is faster than capillary flow. It has been used for liver and tumour flow. Contrast st...

Abstract Therapy of recurrent focal segmental glomerulosclerosis (FSGS) in the renal allograft is largely based on case reports. The use of plasmapheresis alone (based on its effectiveness in children) appears less effective in adults, reaching a response rate of

We report the case of a 25-year-old lung and liver transplant recipient who developed respiratory failure. High levels of Epstein-Barr virus (EBV) genome copies were detectable in respiratory tract specimens, while the search for various other viral, bacterial or fungal pathogens remained empty. Post-transplant lymphoproliferative disease was excluded. Due to the rapid progression of respiratory i...
