Imaging of the carotid body tumor in the neck 

Spiral CT Angiogram of the neck has become the standard method of evaluation to see the relationship of the tumor with the carotid bifurcation and structures in the neck. This tumor is extending far deeper in to the neck under the mandible as seen in the figure. It is important note that distal control of the internal carotid artery is difficult in such cases. Preoperative embolization to reduce the vascularity and special measures may be required to reach the distal end of the internal carotid artery during the excision surgery.

Aspirin in Diabetics for Asymptomatic PAD

Aspirin in Diabetics with asymptomatic Peripheral arterial disease?
In examining why aspirin may have been ineffective, the question was asked as to whether these patients were at sufficient risk, in terms of peripheral arterial disease, as the cut-off point of an ankle brachial pressure index of 0.99 or less is higher than that used to define peripheral arterial disease in the population (<0.9). A subgroup analysis did not, however, find evidence of a difference in effect of aspirin between those with an index of 0.91-0.99 and those below this level. Furthermore, one of the current major interventions in the specialty of diabetes mellitus is statin therapy. Calculations by two of the centres (DM and CK) in over 10 000 people with diabetes showed a mean total cholesterol level of 6.0 mmol/l in 1996 decreasing to 4.3 mmol/l in 2007.
