AFP is normally elevated in infants, and because teratoma is the single most common kind of tumor in infants, several studies have provided reference ranges for AFP in normal infants. [5] [6] [7] Perhaps the most useful is this equation: log Y = 7.397 - 2.622.log (X + 10), where X = age in days and Y = AFP level in nanograms per milliliter. [8]
Functional abdominal pain syndrome is a functional gastrointestinal disorder. [4] Functional gastrointestinal disorders (FGD) are common medical conditions characterized by recurrent and persistent gastrointestinal symptoms caused by improper functioning of the enteric system in the absence of any identifiable organic or structural pathology, such as ulcers, inflammation, tumors or masses.

It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Adoption of ICD-10-CM was slow in the United States. Since 1979, the US had required ICD-9-CM codes [11] for Medicare and Medicaid claims, and most of the rest of the American medical industry followed suit. On 1 January 1999 the ICD-10 (without clinical extensions) was adopted for reporting mortality, but ICD-9-CM was still used for morbidity ...

Risk factors include ascites (the abnormal build-up of fluid in the abdomen) and peritoneal dialysis. [4] Diagnosis is generally based on examination, blood tests, and medical imaging. [6] Treatment often includes antibiotics, intravenous fluids, pain medication, and surgery. [3] [4] Other measures may include a nasogastric tube or blood ...
Alpha-fetoprotein (AFP) is significantly expressed in foetal liver. However, the mechanism that led to the suppression of AFP synthesis in adults is not fully known. Exposure of the liver to cancer-causing agents and arrest of liver maturation in childhood can lead to the rise in AFP. AFP can reach until 400–500 μg/L in hepatocellular ...
