Predicting Therapeutic Response by in vivo Molecular Imaging in Inflammatory Bowel Diseases.

Background: Different invasive and non-invasive imaging modalities are indispensable tools in the management of inflammatory bowel disease (IBD) patients. Standard imaging procedures like white light endoscopy or MRI are used to define gut inflammation based on structural changes and altered morphology of the mucosa. Nevertheless, it has thus far not been possible to analyse biological processes at the cellular level, which drive intestinal inflammation in IBD patients.

Novel Techniques in the Surgical Treatment of Acromegaly: Applications and Efficacy.

Since the establishment of transsphenoidal microsurgery as the operative treatment of choice in most patients with acromegaly 40 years ago, a few novel technical developments have evolved. Their application, utility and efficacy will be briefly discussed in this review article, based on an analysis of published results and the authors' personal experience. The endoscope was additionally used to search for residual tumours in locations which could not be visualised with the operating microscope.

Discordant Clinical Course of Vitamin-D-Hydroxylase (CYP24A1) Associated Hypercalcemia in Two Adult Brothers With Nephrocalcinosis.

Background/aims: Hypercalcemia can result in nephrocalcinosis/nephrolithiasis and may lead to renal failure. Idiopathic infantile hypercalcemia is caused by mutations of the CYP24A1 gene, which regulates vitamin D activity. Classically infants present with hypercalcemia.
