BACKGROUND: Recent studies demonstrated a significant improvement in the diagnostic performance of coronary CT angiography (CCTA) for the evaluation of in-stent restenosis (ISR). However, coronary stent assessment is still challenging, especially because of beam-hardening artifacts due to metallic stent struts and high atherosclerotic burden of non-stented segments. Adenosine-stress myocardial perfusion assessed by CT (CTP) recently demonstrated to be a feasible and accurate tool for evaluating the functional significance of coronary stenoses in patients with suspected coronary artery disease (CAD)...

BACKGROUND: We performed a prospective study to quantify changes in various aspects of upright posture intolerance in patients with intracranial hypotension. METHODS: Six patients were provided a standard questionnaire before, immediately after epidural blood patch injection and at follow-up visit within 1 month after epidural blood injection inquiring: (a) How long can they stand straight without any support? (b) Do they feel any sense of sickness when they sit or lie down after standing? (c) How long do they have to wait before they are comfortable standing again after they have stood straight? (d) How effectively and fast can they get up from sitting or lying position to stand straight? and (e) Rate their activities in upright posture without support on a standard vertical visual analogue scale between 100 (can do everything) and 0 (cannot do anything)...

Cerebral venous sinus thrombosis usually occurs in patients with a precipitating condition such as thrombophilic disorders, pregnancy or due to medications, such as oestrogens. Some case reports have reported the co-occurrence of cerebral venous sinus thrombosis in patients with hyperthyroidism. However, the association of cerebral venous sinus thrombosis with hyperthyroidism remains contentious. We present the case of a patient who presented with a clinical picture of cerebral venous sinus thrombosis with no obvious precipitating factor...

Axillary artery aneurysm is a rare condition. Though mostly asymptomatic, it should be treated early as it can develop thrombosis, distal embolisation, pressure symptoms or rupture. We report here a case of a 24-year woman who presented with neurological deficit in her arm because of pressure by axillary artery aneurysm. Standard treatment of these aneurysms is excision and replacement with an interposition graft. We used reversed saphenous vein as interposition graft between axillary and brachial artery.

To assess the risk posed by a toxic chemical to human health, it is essential to quantify its uptake in a living subject. This study aims to investigate the biological distribution of inhaled polyhexamethylene guanidine (PHMG) aerosol particle, which is known to cause severe pulmonary damage. By labeling with indium-111 (111 In), we quantified the uptake of PHMG for up to 7 days after inhalation exposure in rats. The data demonstrate that PHMG is only slowly cleared, with approximately 74% of inhaled particles persisting in the lungs after 168 h...
