Granulomatosis with polyangiitis (GPA), formerly known as Wegener’s granulomatosis, is a rare form of vasculitis. In this disorder, small-sized blood vessels in the nose, sinuses, ears, lungs and kidneys become inflamed and damaged.

Criterios Diagnóstico para Vértigo Posicional Paroxístico Benigno
Diagnostic Criteria for Benign Paroxysmal Positional Vertigo Vertigo associated with a characteristic mixed torsional and vertical nystagmus provoked by the Dix-Hallpike test A latency (typically of 1 to 2 seconds) between the completion of the Dix-Hallpike test and the onset of vertigo and nystagmus Paroxysmal nature of the provoked vertigo and nystagmus (i.e., an increase … Read more
ACR Criteria for the Classification of Hypersensitivity Vasculitis
Three of the following five criteria were required to meet American College of Rheumatology (ACR) classification criteria for hypersensitivity vasculitis:
Amsel’s Diagnostic Criteria for Bacterial Vaginosis
Three of four criteria must be met; establishes accurate diagnosis of bacterial vaginosis in 90 percent of affected women.
Diagnostic Criteria for Tuberculosis Disease
Definite diagnosis
-
Clinical picture consistent with tuberculosis; bacteriologic confirmation (culture, gene probe/NAA + AFB smear); histologic findings
Diagnostic Criteria for Essential Thrombocytopaenia (ET)
Polycythemia Vera Study Group (PVSG) Diagnostic Criteria for Essential Thrombocytopaenia (ET)
All of the following criteria must be fulfilled to make a diagnosis of ET
-
Platelet count greater than 600 x 109/L
-
Hematocrit less than 40 or normal red blood cell mass
-
Stainable iron in the marrow or normal RBC mean corpuscular volume (If these measurements suggest iron deficiency, polycythemia vera cannot be excluded unless a trial of iron therapy fails to increase the red blood cell mass into the polycythemic range.)
-
No Philadelphia chromosome or bcr/abl gene rearrangement
-
Collagen fibrosis of the bone marrow absent or less than one third of the biopsy area without both marked splenomegaly and a leukoerythroblastic blood film
-
No cytogenetic or morphologic evidence for a myelodysplastic syndrome
-
No cause for a reactive thrombocytosis
Diagnostic Criteria for Heparin-Induced Thrombocytopenia (HIT)
Diagnostic Criteria for Heparin-Induced Thrombocytopenia (HIT)
- Heparin exposure >5 days
- Relative thrombocytopenia: decrease in platelet count by 50% from baseline OR absolute thrombocytopenia: decrease in platelet count to less than 100 to 150 x 109/L
- Absence of other causes of thrombocytopenia
- Development of new thrombosis, or extension of pre-existing thrombosis, while receiving heparin therapy
- Confirmation by laboratory testing
- Return to normal platelet count when heparin is discontinued
Diagnostic Criteria for Thromboangiitis Obliterans (Buerger’s Disease)
Since specificity of Buerger’s disease is characterized by peripheral ischemia of an inflammatory nature and with a self-limiting course, diagnostic criteria should be discussed from clinical of view.
Several different criteria have been proposed for the diagnosis of thromboangiitis obliterans:
Criteria for the Classification of Takayasu Arteritis
Takayasu arteritis (TA) is a chronic large vessel vasculitis that affects aorta, its main branches and pulmonary arteries. The inflammatory process results in stenosis, occlusion, dilation or aneurysm formation in the arterial wall.
Diagnostic Criteria of Infarction in MRI of the Brain in Acute Stroke
Acute: Subtle low signal (hypointense) on T1, often difficult to see at this stage, and high signal (hyperintense) on spin density and/or T2-weighted and proton density-weighted images starting 8 h after onset; should follow vascular distribution. Mass effect maximal at 24 h, sometimes starting 2 h after onset, even in the absence of parenchymal signal changes. No parenchymal enhancement with paramagnetic contrast agent. Territorial intravascular paramagnetic contrast enhancement of “slow-flow” arteries in hyperacute infarcts; at 48 h, parenchymal and meningeal enhancement can be expected.
