Disorders of metabolic obesity with normal body weight (MONW) are widely recognized risk factors for the development of cardiovascular diseases and type 2 diabetes. Despite this, MONW is not diagnosed in clinical practice. Continue reading “Point Scale for Metabolic Obesity in People with Normal Body Weight (MONW)”
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.

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.

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”
For the WHO caries assessment system, the examiner recorded a surface as decayed only if it presented with detectably softened floor, undermined enamel or a softened wall. According to this criterion, all the stages that precede cavitation as well as other conditions similar to the early stages of a carious lesion were considered sound.
For the ICDAS system, the D stands for detection of dental caries by (i) stage of the carious process; (ii) topography (pit and fissure or smooth surfaces); (iii) anatomy (crown vs roots); and (iv) restoration or sealant status. The A in the ICDAS stands for assessment of the carious process by the stage (non-cavitated or cavitated) and activity (active or arrested). This study does not include an assessment of the lesion activity or root caries.

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.

A cost-effective diagnostic workup of patients with possible acute viral hepatitis is the most reasonable approach. Because 75% of cases of acute viral hepatitis result from infection with either HAV or HBV, the initial laboratory investigation should include serologic tests to exclude HAV or HBV. If the results of these studies are negative, further testing should be done to rule out acute HCV infection, which is less common. Serum HCV RNA is detectable 1 to 2 weeks after the onset of infection, whereas anti-HCV can be detected 8 to 10 weeks following infection with the virus. In clinically stable patients, waiting and checking the presence of antibodies to HCV may be plausible. Checking for HCV RNA by polymerase chain reaction in all patients is not cost-effective, unless there is a known history of blood exposure. Finally, not all acute hepatitis is viral. If the initial evaluation fails to show viral hepatitis, then other causes of hepatitis, such as alcoholic hepatitis, drug toxicity, autoimmune hepatitis, or Wilson’s disease, should be considered.

The clinical diagnosis of an epileptic seizure requires a detailed history taking and, ideally, an eyewitness account of the seizure. Evaluation with 12-lead electrocardiography is essential in a patient who has had a first seizure or an unexplained blackout spell.
Patients who have had an epileptic seizure should be informed about factors that may provoke seizures (e.g., sleep deprivation and alcohol use), the risk of a seizure occurring while driving or engaging in solitary activities, and the risks of harm from further seizures.

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”
Hepatic fibrosis is the most important determinant of liver and non-liver outcomes in patients with nonalcoholic fatty liver disease (NAFLD). Therefore, identifying patients with clinically significant hepatic fibrosis (fibrosis stage 2 or higher) is important for targeted efforts at preventing disease progression.
Nonalcoholic steatohepatitis (NASH), a subtype of NAFLD characterized by inflammation, ballooning, and Mallory’s hyaline on liver biopsy, can lead to hepatic fibrosis, cirrhosis, and hepatocellular cancer (HCC). Both NAFLD and NASH are also associated with an increased risk of cardiovascular disease, cardiovascular and liver-related mortality, and impaired health-related quality of life.
