Myocarditis may present with a wide range of symptoms, ranging from mild dyspnea or chest pain that resolves without specific therapy to cardiogenic shock and death. Dilated cardiomyopathy with chronic heart failure is the major long-term sequela of myocarditis. Most often, myocarditis results from common viral infections; less commonly, specific forms of myocarditis may result from other pathogens, toxic or hypersensitivity drug reactions, giant-cell myocarditis, or sarcoidosis.
Criteria
NIH Diagnostic Criteria for Neurofibromatosis
Neurofibromatosis 1 and neurofibromatosis 2 are autosomal dominant genetic disorders in which affected individuals develop both benign and malignant tumors at an increased frequency.
Diagnostic Criteria for Zollinger-Ellison Syndrome (ZES)
Zollinger-Ellison (ZES) syndrome is characterized by gastric acid hypersecretion resulting in severe acid-related peptic disease and diarrhea.
Diagnostic Criteria for Wilson’s disease
Wilson’s disease is clinically characterised by hepatic and neurological manifestations related to the accumulation of copper in the liver and the lenticular nuclei, and by Kayser-Fleischer rings.
Criteria for the Classification of Wegener’s Granulomatosis (WG)
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
