What Went Wrong with VEGF-A in Peripheral Arterial Disease? A Systematic Review and Biological Insights on Future Therapeutics.

Background: Of the 200 million patients worldwide affected by peripheral arterial disease (PAD), 4% will inevitably require major limb amputation. Previous systematic reviews presented a conflicting body of evidence in terms of vascular endothelial growth factor (VEGF) family member effects upon PAD natural progression. Despite that, modulation of intrinsic angiogenesis mechanisms targeting the VEGF family members still confers an attractive therapeutic target.

Bilateral adrenal haemorrhage complicated by sepsis, coagulopathy, influenza A and adrenal crisis.

Bilateral adrenal haemorrhage is a rare and often fatal condition that most commonly occurs under conditions of severe physiological stress. We describe a 33-year-old male patient with ulcerative colitis who presented with acute worsening epigastric pain, vomiting and raised inflammatory markers. Initial differentials included gastritis and peptic ulceration.
