Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy that predominantly affects the right ventricle. With a prevalence in the range of 1:5000 to 1:2000 persons, ARVC is one of the leading causes of sudden cardiac death in young people and in athletes.
Criteria
IWOS Criteria for the Diagnosis of Ocular Sarcoidosis (OS)
Sarcoidosis is a systemic inflammatory disorder with unknown aetiology, affecting many organs including the eye and characterised by non-caseating granulomas.
Diagnostic Criteria for Behavioural Variant Frontotemporal Dementia
Frontotemporal dementia (FTD) is a neurodegenerative disorder mainly affecting the frontal and/or temporal lobes, leading to dementia with prominent behavioural and/or language disturbances. Symptom onset is most often between 45 and 65 years.
Diagnostic Criteria for Chronic Rhinosinusitis with Nasal Polyps
Nasal polyps are benign inflammatory masses, arising from the mucosa of the nose and paranasal sinuses. They are considered to be a subgroup of chronic rhinosinusitis, and clinical diagnosis is made on the basis of the presence of sinonasal symptoms for more than 3 months and the visualization of polyps in the nasal cavity.
Criteria to Initiate Evaluation for Growth Hormone Deficiency (GHD)
Tools for the diagnosis of GHD include auxology, radiographic assessment of bone age, measurement of insulin-like growth factor 1 (IGF-I) and IGF binding protein 3 (IGFBP-3), provocative growth hormone (GH) testing, cranial magnetic resonance imaging (MRI), and, in certain cases, genetic testing. Growth velocity and the degree of short stature are primary considerations in the decision to pursue evaluation for GHD.
Diagnosis and Severity Criteria for Sinusoidal Obstruction Syndrome/Veno-Occlusive Disease in Children
Hepatic sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) is a life-threatening complication of hematopoietic cell transplantation (HCT) that belongs to a group of diseases increasingly identified as transplant-related, systemic endothelial diseases. In most cases, SOS/VOD resolves within weeks; however, severe SOS/VOD results in multi-organ dysfunction/failure with a mortality rate >80%.
GLIM Criteria for the Diagnosis of Malnutrition
This Global Leadership Initiative on Malnutrition (GLIM) initiative targets the priority to adopt global consensus criteria so that malnutrition prevalence, interventions, and outcomes may be compared throughout the world.
Diagnostic Criteria and Severity Grading of Acute Cholecystitis (TG18)
The diagnostic criteria for acute cholecystitis have high sensitivity (91.2%) and specificity (96.9%) and good diagnostic yield; therefore, their use as the diagnostic criteria for acute cholecystitis is recommended.
Diagnostic Criteria for Idiopathic Pulmonary Fibrosis (IPF)
In 2000, IPF was defined as a specific form of chronic, progressive, fibrosing interstitial pneumonia of unknown cause, occurring primarily in older adults and limited to the lungs. Usual interstitial pneumonia (UIP) is the histopathological pattern of IPF. IPF is characterized by progressive worsening of dyspnea and lung function and is associated with a poor prognosis.
Criteria for Essential Tremor
Essential tremor is considered to be a tremor syndrome characterized by isolated bilateral upper-limb action tremor with a duration of at least 3 years, with or without tremor in other locations, such as head, larynx (voice tremor), or lower limbs.
Essential tremor frequently manifests with additional mild neurologic signs of diagnostic uncertainty, such as mild ataxia, questionably abnormal posturing of the limbs, or impaired memory. This presentation is classified as “essential tremor plus.
