These non-invasive methods can be used for NAFLD screening but are not accepted as a substitute for liver biopsy in NAFLD nor NASH clinical trials, as only a liver biopsy can define liver pathology.Ultrasound presented average sensitivity and specificity for diagnosing the disease in children, while in the adult population, sensitivity and specificity were significantly higher. Proton density fat fraction magnetic resonance imaging has been increasingly used for the diagnosis of steatosis in pediatric patients. Elastography is an effective tool for staging liver fibrosis and discriminating NASH from NAFLD in children.CT scans and MRIs are more accurate in detecting cirrhosis than conventional ultrasound. Transient elastography is recommended for the initial assessment of liver fibrosis and cirrhosis and helps to predict complications and prognosis, but the interpretation of results is carefully weighed in the presence of limiting factors, such as steatosis, high BMI, lower degrees of hepatic fibrosis and narrow spaces between the ribs (intercostal spaces). However, transient elastography can fail for people with pre-hepatic portal hypertension. Transient elastography is not considered to be a replacement for liver biopsy.Magnetic resonance elastography (MRE) is an emerging method that can accurately assess hepatic fibrosis and is recommended by the APASL. MRE possesses a good sensitivity to quantify hepatic fat and excellent accuracy to detect fibrosis in NAFLD regardless of BMI and inflammation and is suggested as a more reliable alternative to diagnose NAFLD and its progression to NASH compared to ultrasound and blood tests.
Hystrix-like ichthyosis with deafness syndrome
HID syndrome is also known as ichthyosis hystrix, Rheydt type after the German city of Rheydt near Düsseldorf where it was first discovered. Symptoms are bilateral hearing loss and spiky hyperkeratotic masses which cover the whole body though the palms and soles are less badly affected. It can be differentiated from KID syndrome which also has symptoms of deafness and ichthyosis by the different distribution of hyperkeratosis. It is an autosomal dominant condition caused by a mutation to the GJB2 gene (the same gene affected by KID syndrome). Ichthyosis hystrix, Baefvertstedt type
An extremely rare disease of which only a few isolated cases are known. See also
