Diagnostic Criteria for Fracture-Related Infection (FRI)

Fracture-related infection (FRI) is a severe complication following bone injury and can pose a diagnostic challenge. There is a spectrum of clinical presentations of FRI and differentiating them from noninfected causes can be difficult. In the early postoperative period, classical clinical symptoms of infection, such as pain, redness, warmth, or swelling, overlap with features of normal fracture healing. Later, more subtle clinical presentations such as fracture nonunion or persistent pain can be attributable to both infective and noninfective conditions. The complexity and variety of FRI may have hindered the establishment of uniform diagnostic criteria.

Diagnostic Criteria of Acute Rejection in Kidney Transplants

The gold standard for diagnosing acute rejection in kidney transplant recipients is tissue biopsy. Indications to pursue graft biopsy over concern for acute rejection include either an acute, otherwise unexplained deterioration in graft function or the presence of a biomarker consistent with acute rejection.

Diagnostic Criteria for Infantile Spasms and West Syndrome

West syndrome is characterized by a specific type of seizure ( infantile spasms) and developmental regression.

The gold standard method of diagnosing infantile spasms is to capture them on video-EEG to confirm the ictal correlate of the seizure. Continue reading “Diagnostic Criteria for Infantile Spasms and West Syndrome”

Diagnostic Scoring System for Wilson’s Disease

Normal dietary consumption and absorption of copper exceed the metabolic need, and homeostasis of this element is maintained exclusively by the biliary excretion of copper. Wilson’s disease is an inherited disorder in which defective biliary excretion of copper leads to its accumulation, particularly in liver and brain. Continue reading “Diagnostic Scoring System for Wilson’s Disease”

New Diagnostic Criteria for Arrhythmogenic Cardiomyopathy

These new insights into the heterogeneous genetic mutations and phenotypic manifestations of ACM led to a critical revision of the 2010 ITF criteria, which exclusively targeted RV classical forms and did not include the tissue characterization by contrast enhanced cardiac magnetic resonance (CMR) imaging. Accordingly, an International Expert consensus document has been recently developed to provide upgraded criteria (“the Padua Criteria”) for the diagnosis of the whole spectrum of ACM phenotypes. Continue reading “New Diagnostic Criteria for Arrhythmogenic Cardiomyopathy”

Revised Diagnostic Criteria for Paraneoplastic Pemphigus (PNP)

Paraneoplastic pemphigus (PNP) is a rare and life-threatening autoimmune bullous disease that classically occurs in the setting of an underlying neoplasm. PNP is also known as paraneoplastic autoimmune multiorgan syndrome (PAMS) because of its varied mucocutaneous and systemic deleterious effects. Due to the variable disease characteristics and lack of formally accepted diagnostic criteria, PNP remains a diagnostic challenge for clinicians. Continue reading “Revised Diagnostic Criteria for Paraneoplastic Pemphigus (PNP)”

Revised Physical Diagnostic Criteria for Osteosarcopenic Obesity (OSO)

Osteosarcopenic obesity (OSO) syndrome describes the simultaneous deterioration of bone, muscle and excess fat, resulting in reduced functionality and systemic metabolic dysregulation. The key component contributing to this may be ectopic fat in the viscera, bone and muscle. Continue reading “Revised Physical Diagnostic Criteria for Osteosarcopenic Obesity (OSO)”

Rome IV Diagnostic Criteria for Belching Disorders

Gas, bloating, and belching are associated with a variety of conditions but are most commonly caused by functional gastrointestinal disorders. These disorders are characterized by disordered motility and visceral hypersensitivity that are often worsened by psychological distress. Continue reading “Rome IV Diagnostic Criteria for Belching Disorders”

Rome IV Diagnostic Criteria for Nausea and Vomiting Disorders

Nausea is a subjective symptom and can be defined as an unpleasant sensation of the imminent need to vomit, typically experienced in the epigastrium or throat. Vomiting refers to the forceful oral expulsion of gastrointestinal contents associated with contraction of the abdominal and chest wall muscles. Continue reading “Rome IV Diagnostic Criteria for Nausea and Vomiting Disorders”

Revised Diagnostic Criteria for Neurofibromatosis Type 1 (NF1)

Neurofibromatosis type 1, inherited in an autosomal dominant pattern, is characterized by multiple café-au-lait macules (CALMs), skinfold freckling (more correctly termed lentiginous macules since they occur in non–sun exposed areas), iris Lisch nodules, tumors of the nervous system, and other features.
