Bilateral external iliac vein compression-An important consideration in implantation of leadless permanent pacemaker.

We report on an unusual case with asymptomatic bilateral external iliac vein non-thrombotic obstruction causing difficulty in delivery of the leadless permanent pacemaker and discuss on the strategies to overcome the problem.

A spuriously 'normal' haemoglobin A1c result.

We report a case of spuriously 'normal' haemoglobin A1c (HbA1c) result due to misidentification of HbG Taipei as HbAo by the Variant II built-in retention time algorithm. The defect was circumvented effectively by the implementation of a chromatographic system specific internal quality control mechanism for peak identity verification. HbA1c and estimated average glucose results were corrected from 4.
