An Update on the Treatment and Management of Cellulitis.

Cellulitis and erysipelas are local soft tissue infections that occur following the entry of bacteria through a disrupted skin barrier. These infections are relatively common and early diagnosis is essential to treatment success. As dermatologists, we need to be familiar with the clinical presentation, diagnosis, and treatment of these infections.

Diagnosis of early Takayasu arteritis with sonography.

Objective: Takayasu arteritis is a large-vessel vasculitis that occurs predominantly in young females. The diagnosis is not usually established before arterial stenoses or occlusions are present. The aim of the study was to find out if sonography can aid in the diagnosis of the disease in earlier stages.

Vasculitis of the internal carotid artery in Wegener's granulomatosis: comparison of ultrasonography, angiography, and MRI.

A 37-year old male with newly diagnosed, untreated Wegener's granulomatosis including glomerulonephritis, sinusitis, conjunctivitis, arthralgias, and positive cANCA, developed a pulsating tumor in the left submandibular region and a reversible ischemic neurologic deficit. Ultrasonography revealed both a hyperechoic wall thickening of the left proximal internal carotid artery as is known in Takayasu's arteritis and a surrounding hypoechoic region typical for perivasculitis. The wall thickening and the perivascular infiltrate could be less clearly seen by MRI.
