Non communicable diseases

Non-communicable diseases (NCDs)
Infectious diseases were given maximum attention in the past. All the Governments (health departments) in different countries focused on the prevention and treatment of infectious diseases and controlled their spread. Now they are realizing that the non-communicable disease related morbidity and mortality is increasing across the world. It was initially thought that this is a phenomenon only in the developed nations and urban societies. Some studies have shown that it is the poor nations who are going to see this change and its effects. Even the rural people are also going to be affected like the urban populations. This will be affecting the economic status of the people and countries.

New Light On Detection of Bacterial Infection: Polymers Fluoresce in the Presence of Bacteria


Professor Sheila MacNeil, an expert in tissue engineering and wound healing, explained: "The polymers incorporate a fluorescent dye and are engineered to recognise and attach to bacteria, collapsing around them as they do so. This change in polymer shape generates a fluorescent signal that we´ve been able to detect using a hand-held UV lamp."

Imaging inflammatory Large Vessel Vasculitides (LVV)

Young lady (22 years) came to the vascular surgery clinic with low-grade fever, loss of weight, body pains, tenderness in the carotid triangle and weak radial pulsations in both the hands. There were no vascular risk factors or joint pains. Giant-cell arteritis (GCA) and Takayasu’s arteritis (TA) are the commonest large-vessel vasculitides (LVV) in such patients. Imaging studies are increasingly being used to diagnose and to monitor LVV. The aim of this presentation is to discuss a case and review the literature on imaging studies.

Imaging studies play a central role in diagnosing and monitoring the large vessel vasculitides (giant-cell and Takayasu’s arteritis). CT or MRI, TEE can examine the deep and central large vessels, while color Doppler ultrasound and MRI have been used with promising results to investigate the temporal arteries. Positron emission tomography is very sensitive in detecting large-vessel inflammation, although it does not delineate the vessel wall. Imaging procedures can also be used to monitor the disease course. However, imaging signs of inflammation may sometimes persist despite clinical remission and, conversely, seemingly unaffected vessels may develop alterations later on. The commonest angiographic findings in Takayasu’s disease are long, smooth vascular stenoses and sometimes occlusions and aneurysms. However, angiography cannot demonstrate early vasculitic lesions such as vessel wall alterations and is thus not useful for early diagnosis.

Stroke and intracranial interventions

Can interventions for Intracranial vascular disease prevent stroke better than medical therapies?

Carotid artery disease is recognized as a predisposing factor for the stroke in the diabetic or elderly hypertensive patients. The stroke in such patients is prevented by medical therapies and interventions. Segmental extra cranial carotid artery disease is amenable for endarterectomy or angioplasty stenting. But the intracranial vascular disease is not easily amenable for the operations or interventions. After succeeding with angioplasty and stenting of the extra cranial vessels the attention is now focused on the intracranial vascular repairs with angioplasty and stenting. The intracranial vessels are small and delicate. They can need much more careful handling and softer devices to pass through them and at the same time hard enough to dilate stenotic lesions.The 30-day rate of stroke or death associated with stenting in the SAMMPRIS trial (14.7%) is nearly 2.5 times as high as the 6% rate associated with stenting of symptomatic extracranial carotid-artery stenoses in the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST, NCT00004732).
