What is the minimum serum bilirubin level in neonates that requires phototherapy treatment?

Oral isotretinoin is known to induce side effects in some people despite only being taken for a short period of time. Besides skin dryness, triglyceride (TG) and liver enzyme elevations are the commonest biochemical changes expected in the blood. The skin specialists who prescribe isotretinoin will usually monitor the TG and liver function of their patients on a regular basis. Mild elevation of these blood markers does not require any intervention. This is because the treatment duration usually last only 3-6 months. Once treatment ends, the elevated TG and liver enzymes should normalise.

CA19-9 is traditionally taken as a cancer marker for the pancreas. This marker is unfortunately not specific and can also be found in patients with bile duct, stomach and colon cancers. Unknown to many, an elevation of this tumour marker is commonly seen in people with inflammation of the pancreas as well as bile duct obstruction due to stone disease. As your CA19-9 is well within normal limits, there is no reason why you should be concerned especially if there is no risk factor such as personal or family history of cancers involving the liver, bile duct or pancreas.
