ANCA--Associated Small-Vessel Vasculitis
ANCA–Associated Small-Vessel Vasculitis ISHAK A. MANSI, M.D., PH.D., ADRIANA OPRAN, M.D., and FRED ROSNER, M.D. Mount Sinai Services at Queens Hospital Center, Jamaica, New York and the Mount Sinai School of Medicine, New York, New York Antineutrophil cytoplasmic antibodies (ANCA)–associated vasculitis is the most common primary sys- temic small-vessel vasculitis to occur in adults. Although the etiology is not always known, the inci- dence of vasculitis is increasing, and the diagnosis and management of patients may be challenging because of its relative infrequency, changing nomenclature, and variability of clinical expression. Advances in clinical management have been achieved during the past few years, and many ongoing studies are pending. Vasculitis may affect the large, medium, or small blood vessels. Small-vessel vas- culitis may be further classified as ANCA-associated or non-ANCA–associated vasculitis. ANCA–asso- ciated small-vessel vasculitis includes microscopic polyangiitis, Wegener’s granulomatosis, Churg- Strauss syndrome, and drug-induced vasculitis. Better definition criteria and advancement in the technologies make these diagnoses increasingly common. Features that may aid in defining the spe- cific type of vasculitic disorder include the type of organ involvement, presence and type of ANCA (myeloperoxidase–ANCA or proteinase 3–ANCA), presence of serum cryoglobulins, and the presence of evidence for granulomatous inflammation. Family physicians should be familiar with this group of vasculitic disorders to reach a prompt diagnosis and initiate treatment to prevent end-organ dam- age. Treatment usually includes corticosteroid and immunosuppressive therapy. (Am Fam Physician 2002;65:1615-20.

Primary systemic vasculitides are rare diseases that may manifest similarly to more commonly encountered conditions. Depending on the size of the vessel affected (large vessel, medium vessel, or small vessel), different vasculitis mimics must be considered. Establishing the right diagnosis of a vasculitis mimic will prevent unnecessary immunosuppressive therapy. 1. Introduction 2. Large-Vessel Vasculitis Mimics Vasculitides are rare heterogenous diseases that affect vessel Large-vessel vasculitis (LVV) is an inflammatory vascu- walls as the main site of inflammation. Organs affected vary lopathy affecting large arteries; giant cell arteritis (GCA) depending on the type and size of blood vessels involved and Takayasu’s arteritis (TAK) are the two main docu- [1].

PMR) / Giant Cell Arteritis (GCA
Arthritis and Rheumatology Clinics of Kansas Patient Education Polymyalgic Rheumatica (PMR) / Giant Cell Arteritis (GCA) Introduction: PMR and GCA are related conditions affecting adults over the age of 50. Both are inflammatory diseases, with PMR involving the large joints of the hips and/or shoulders and GCA involving large and medium sized blood vessels. PMR occurs in about 30 individuals over the age of 50 per 100,000 population per year, while GCA is roughly half as common. Both conditions are about twice as common in women as in men and are seen most commonly in those of Northern European descent. The average age of onset is about 70 for both conditions, and with the aging population the prevalence of these disorders is expected to increase in the next few decades. While the cause of these conditions is unknown, the fact that they tend to occur in cooler climates and in clusters of cases every several years suggests that infections may trigger PMR and GCA. Having certain genes also seems to increase the risk of developing either of these disorders. Features of PMR: Patients with PMR tend to experience widespread pain in the regions of the shoulders, upper arms, neck, hips, buttock, and thighs. These symptoms may be sudden in onset and are accompanied by up to several hours of morning stiffness. While swelling of knees, elbows, or wrists may occur, there is most often no visible joint swelling but only difficulty with movement of the larger joints. A small percentage of patients may experience swelling of the entire hand and foot with edema, or excess fluid accumulation. -

History of Psoriasis and Parapsoriasis
History of Psoriasis and Parapsoriasis By Karl Holubar Summary Parapsoriasis is «oï a disease entity. Jt is an auxiliary term introduced in J 902 to group several dermatoses w>itk a/aint similarity to psoriasis. Tlie liistorical development leading to tlie creation o/ t/ie term parapsoriasis is outlined and t/te Itistory o/psoriasis is 6rie/ly reviewed. Semantic and terminological considerations Obviously, para-psoriasis as a term has been created in analogy to psoriasis. We should remember similar neologisms in medical language, e. g. protein and para-protein; typhoid and para-typhoid, thyroid and para-thyroid, phimosis and para-phimosis, eventually, pemphigus and para-pemphigus (the latter in 1955 this term was to be employed instead of pemphigoid but was not accepted by the dermatological world). Literally, para is a Greek preposition, (with the genitive, dative and accusative), meaning: by the side of, next to something, alongside something. In medicine, para is used often as a prefix to another term, which designates a condition somewhat similar to the one under consideration. The same holds for psoriasis and parapsoria- sis. In detail, though, it is a bit more complicated. Parapsoriasis has more than one "/at/ier", three in fact: ideiurick /Iu.spitz f 1835—1886,), Paul Gerson Luna (A850—1929j and Louis Procç fI856—I928J. Auspitz, in 1881, had published a new system of skin diseases the seventh class of which was called epidermidoses, subdivided into liypcrlcfiratose.s, parakeratoses, kerato/y- ses, the characteristics of which were excessive keratinization, abnormal keratinization and insufficent keratinization. When Unna, in 1890®, pub- lished his two reports on what he called parakeratosis variegata, he referred to Auspitz' system and term when coining his own. -
