Euthyroid sick syndrome (ESS), sick euthyroid syndrome (SES), thyroid allostasis in critical illness, tumours, uremia and starvation (TACITUS), non-thyroidal illness syndrome (NTIS) or low T3 low T4 syndrome is a state of adaptation or dysregulation of thyrotropic feedback control where the levels of T3 and/or T4 are ...
Arterial line placement is a common procedure in various critical care settings. Intra-arterial blood pressure (BP) measurement is more accurate than measurement of BP by noninvasive means, especially in the critically ill. [1] Intra-arterial BP management permits the rapid recognition of BP changes that is vital for patients on continuous infusions of vasoactive drugs. Arterial cannulation also allows repeated arterial blood gas samples to be drawn without injury to the patient.
More than three decades on from its first outbreak, HIV/AIDS remains a prevalent killer, even in the developed world, and a pressing scientific challenge to understand and treat. The rate of infection, especially among young people, is increasing, and in parts of Africa in particular, it remains an epidemic-scale killer. Yet a cure could be just around the corner, and scientists are optimistic that the virus’ days might be numbered. Is HIV here to stay, or will it be consigned to history like Smallpox?

Every day we’ll upload a new episode that takes you to the heart of the most intriguing and relevant science-related stories of the day, transforming your perspective of the issues shaping our world.
3D scans show still pictures of your baby in three dimensions. 4D scans show moving 3D images of your baby, with time being the fourth dimension. It's natural to be really excited by the prospect of your first scan. But some mums find the standard 2D scans disappointing when all they see is a grey, blurry outline.
Cardiac cath is performed to find out if you have disease of the heart muscle, valves or coronary (heart) arteries. During the procedure, the pressure and blood flow in your heart can be measured. Coronary angiography is done during cardiac catheterization.
patient has fever, hypotension, swelling, and erythema of his left leg. Notably, his leg is more painful to palpation than might be expected after visual inspection. These symptoms are very concerning for necrotizing fasciitis. Necrotizing fasciitis is a fulminant infection of the subcutaneous tissue that spreads rapidly along the fascial planes and leads to extensive tissue necrosis and shock. Treatment • Requires surgical debridement & broad-spectrum antibiotics
The headache, lethargy, and neck stiffness suggest subarachnoid hemorrhage secondary to rupture of a mycotic aneurysm. Mycotic or infected arterial aneurysms can develop due to metastatic infection from IE, with septic embolization and localized vessel wall destruction in the cerebral (or systemic) circulation. Intracerebral mycotic aneurysms can present as an expanding mass with focal neurologic findings or may not be apparent until aneurysm rupture with stroke or subarachnoid hemorrhage. The diagnosis of mycotic cerebral aneurysm can usually be confirmed with computed tomography angiography. Management includes broad-spectrum antibiotics (tailored to blood culture results) and surgical intervention (open or endovascular).
he Allium Ureteral Stents are intended for temporary long or short-term use in malignant or benign chronic Ureteral Stenosis. Allium Ureteral Stents are mounted on a ready to use 8 or 10Fr delivery system. By using the appropriate delivery system their deployment procedure can be performed either retrogradely or percutaneously. Indicated for all chronic ureteral stricturesLarge caliber for intra-lumenal flowLong dwelling timeAntegrade or retrograde insertionEasy insertion and stent positioningExcellent patient comfortNo tissue in-growthAnti-reflux designEasy removal of the device
