Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign , having many causes, which can broadly be broken down into infection , hepatic tumours , and metabolic disorder . Often, hepatomegaly presents as an abdominal mass .
The liver span is a measurement performed during physical examination to determine the size of the liver and identify possible hepatomegaly.. It is the distance between the lower border of the liver in the mid-clavicular line obtained by palpation, and the upper border of the liver in the mid-clavicular line detected by percussion (the upper border of the liver lies behind the ribs and can not ...
Histological diagnosis by liver biopsy is the most accurate measure of fibrosis and liver fat progression as of 2018. [8] Conventional imaging methods, such as ultrasound, CT and MRI, are not specific enough to detect fatty liver disease unless fat occupies at least 30% of the liver volume. [33]
Ultrasonography of the liver with some standard measurements [6] In patients with deranged liver function tests, ultrasound may show increased liver size (hepatomegaly), increased reflectiveness (which might, for example, indicate cholestasis), gallbladder or bile duct diseases, or a tumor in the liver.
Meningitis A, C, Y and W-135 vaccines can be used for large-scale vaccination programs when an outbreak of meningococcal disease occurs in Africa and other regions of the world. Whenever sporadic or cluster cases or outbreaks of meningococcal disease occur in the US, chemoprophylaxis is the principal means of preventing secondary cases in ...
The genome size of strain H44/76 is 2.18 Mb, and encodes 2,480 open reading frames (ORFs), compared to 2.27 Mb and 2,465 ORFs for MC58. [19] Both strains have a GC content of 51.5%. [19] A comparison with MC58 showed that four genes are uniquely present in H44/76 and nine genes are only present in MC58.

An enlarged spleen, which normally measures less than 11–12 cm (4.3–4.7 in) in adults, may suggest underlying portal hypertension. [66] Ultrasound may also screen for hepatocellular carcinoma and portal hypertension. [44] This is done by assessing flow in the hepatic vein. [67] An increased portal vein pulsatility may be seen.
