The Psoriasis Area Severity Index (PASI) is a tool used to measure the severity of psoriasis, a chronic autoimmune skin condition characterized by red, scaly patches on the skin. PASI takes into account the extent of psoriatic involvement (area) as well as the severity of erythema (redness), induration (thickness), and desquamation (scaling) present within the involved regions. It provides a quantitative assessment of psoriasis severity and is commonly used in clinical trials and practice to monitor disease progression and treatment efficacy.
Severity
Characteristics and Management of Covid-19 According to Disease Severity
Evaluation and management of Covid-19 depend on the severity of the disease. Patients with mild disease usually recover at home, whereas patients with moderate disease should be monitored closely and sometimes hospitalized.
Diagnostic Criteria for Anorexia Nervosa (DSM-V)
Anorexia nervosa is a severe psychiatric disorder characterized by starvation and malnutrition, a high prevalence of coexisting psychiatric conditions, marked treatment resistance or no response to treatment, frequent medical complications, and a substantial risk of death.
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%.
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.
Severity Criteria for Clostridium difficile Infection
Patients with severe disease may develop a colonic ileus or toxic dilatation and present with abdominal pain and distension but with minimal or no diarrhea. Complications of severe C. difficile colitis include dehydration, electrolyte disturbances, hypoalbuminemia, toxic megacolon, bowel perforation, hypotension, renal failure, systemic inflammatory response syndrome, sepsis, and death.
Diagnosis and Determination of Severity of Acute Cholecystitis
Acute cholecystitis is a very common complication of cholelithiasis, and as such is frequently encountered in surgical practice. TG07 diagnostic criteria are recognized as those to be recommended in current care for acute cholecystitis.
International Clinical Diabetic Retinopathy and Diabetic Macular Edema Disease Severity Scales
The levels in this new diabetic retinopathy disease severity scale consist of five scales with increasing risks of retinopathy.
CURB-65 and CRB-65 Severity Scores for Community-Acquired Pneumonia (CAP)
CURB and CRB-65 scores can be used in the hospital and out-patients setting to assess pneumonia severity and the risk of death.
Severity Criteria for Acute Pancreatitis
Ranson Criteria to Predict Severity of Acute Pancreatitis
1. When three or more of the following are present on admission, a severe course complicated by pancreatic necrosis can be predicted with a sensitivity of 60-80%:
