In daily clinical practice, it is not so easy to make a confirma-tive diagnosis of food allergy. Interpretation of skin prick test and serum food-specific IgE (sIgE) test results is influenced by detailed clinical history of an individual patient, but ingested foods which provoke adverse reactions often contain many ingredients and lead to a misdiagnosis of food allergy. Oral food challenge is ...

BACKGROUND Although frequently used for tumor surveillance, the sensitivity of carcinoembryonic antigen (CEA) to detect recurrent colorectal cancer (CRC) is not optimal. Fluorine 18-fluoro-2-deoxy-glucose-positron emission tomography (18F FDG-PET) scans promise to improve recurrent CRC detection. We aimed to review PET scans of patients with clinically and/or radiologically suspicious tumor rec...
