Preparedness for and response to an attack involving It is notable that both anthrax and smallpox may biological agents are complicated by the large number be difficult to diagnose at first. Both may show signs and of potential agents (most of which are rarely encountered symptoms similar to those seen with flu, including fever, naturally), their sometimes long incubation periods and chills and muscle aches. Anthrax resulting from consequent delayed onset of disease, and their potential inhalation of spores is the form of illness that would likely for secondary transmission.

They are the second most common vessel (after abdominal aorta) to be affected in atherosclerosis cheap levlen online american express birth control for 9 years. An aneurysm is a localized abnormal dilation of a blood vessel or the heart); it can be congenital or acquired buy levlen with a mastercard birth control kidney pain. When an aneurysm involves an intact attenuated arterial wall or thinned ventricular wall of the heart buy discount benadryl 25mg on-line, it is called a true aneurysm. Moreover, infections with these or- ganisms are exceedingly common (as is atherosclerosis), so that distinguishing coincidence from causality is diffcult. Ans (c) Hyaline arteriosclerosis (Ref: Robbins 9/e p490, 8/e p495) The following are the two patterns of vascular changes in hypertension Hyaline Arteriolosclerosis Hyperplastic Arteriolosclerosis • Vascular lesion consists of a homogeneous, pink, hyaline • Vascular lesion has onionskin, concentric, laminated thickening of the walls of arterioles with loss of underlying thickening of the walls of arterioles with progressive narrowing structural detail, and with narrowing of the lumen of the lumina • Seen in the elderly, hypertensive and diabetic • Seen in but not exclusively in malignant hypertension, • Hyaline arteriolosclerosis is more generalized and more • Frequently accompanied by deposits of fbrinoid and acute severe in patients with hypertension. Kawasaki’s disease affects children but the presentation is fever, cervical lymphadenopathy, skin rash, oral ulcers, con- junctivitis and edema of hands and feet. However, Robbins confuses the issue by mentioning that Hypersensitivity vasculitis is the other name of microscopic angiitis. Direct quote from Harrison 18th/2798 ‘Post capillary venules are the most commonly involved vessels; capillaries and arterioles may be involved less frequently’. They dramatically ameliorate glomerular injury in pauci-immune glomerulonephritis. Medium-sized vessel vasculitis: (a) Polyarteritis nodosa: Glomerulonephritis is absent (b) Kawasaki disease: coronary arteries are often involved, usually occurs in children. Small vessel vasculitis: (a) Wegner granulomatosis: Necrotizing glomerulonephritis is common (b) Churg-strauss syndrome: Associated with asthma and blood eosinophilia (c) Microscopic polyangitis: Necrotizing glomerulonephritis and pulmonary capillaritis (d) Henoch-Schonlein purpura: Vasculitis with IgA- dominant immune deposits (e) Essential cryoglobulinemic vasculitis: Skin and glomeruli are often involved. Segmental thrombosing vasculitis often extending into contiguous veins and nerves (a feature rarely seen in other types of vasculitis), encasing them in fbrous tissue. Temporal arteritis commonly produces visual disturbances including blindness due to involvement of the ophthalmic artery.

Such tumors have sympathetic connections and are chromaffn-positive, a stain that detects catecholamines. These are innervated by the parasympathetic nervous system and infrequently release catecholamines Important points about carotid body tumour The carotid body tumor is a prototype of a parasympathetic paraganglioma. The microscopic features include presence of nests (Zellballen) of round to oval chief cells (neuroectodermal in origin) that are surrounded by delicate vascular septae.
