Risk for Colorectal Cancer in Patients with Serially Positive Fecal Immunochemistry Test in an Annual Screening Program.

Objectives: There are patients who do not undergo colonoscopy even if the fecal immunochemistry test (FIT) results are positive and even with repeated positive test results the following year. We aimed to investigate colorectal cancer (CRC) risk in examinees with positive FIT results in our annual screening program.

Methods: We analyzed patients who underwent initial colonoscopy from April 2010 to March 2017 because of positive FIT results using an endoscopy database in our hospital.

Evidence of transport of styrene oligomers originated from polystyrene plastic to oceans by runoff.

This study demonstrates for the first time that styrene oligomers (SOs), which are indicators of polystyrene (PS) plastic contamination in the environment, are transported from land to the ocean. Samples of sand and seawater were taken from the coastline of the Tokyo Bay over the past four years, and all samples of both sand and seawater were found to contain SOs such as styrene monomer (SM), styrene dimers (SD), and styrene trimers (ST), with the concentration distributions of these being in the order of ST > SD > SM. The concentrations of these SOs are linearly proportional to monthly precipitation.

Risk of colorectal cancer for fecal immunochemistry test-positive, average-risk patients after a colonoscopy.

Background And Aim: Because the risk of colorectal cancer has not been well examined in fecal immunochemistry test (FIT)-positive patients who previously underwent colonoscopy, this study aimed to investigate this topic.

Methods: This was a single-center, observational study of prospectively collected data in Japan. FIT-positive, average-risk patients who underwent colonoscopy were divided into groups as follows: those who never underwent colonoscopy in the past (no colonoscopy group), those with a history of colonoscopy between 6 months and 5 years (0.

[Multiple small intestinal ulcers associated with protein-losing enteropathy secondary to cholesterol crystal embolism:a case report].

A 78-year-old man with hypertension, nephrosclerosis, and angina pectoris visited his family doctor with a history of fatigue and leg edema. He had a history of percutaneous coronary intervention 5 years prior, and was taking low-dose aspirin. Blood tests revealed hypoalbuminemia, gastrointestinal Tc-HSA scintigraphy was positive, and alpha-1 antitrypsin clearance was high;therefore, the hypoalbuminemia was thought to be secondary to a protein-losing enteropathy.
