Some protocols recommend eating a maximum of 10 g of gluten per day for six weeks. Nevertheless, recent studies have shown that a two-week challenge of 3 g of gluten per day may induce histological and serological abnormalities in most adults with proven celiac disease. This new proposed protocol has shown higher tolerability and compliance. It has been calculated that its application in secondary-care gastrointestinal practice would identify celiac disease in 7% of patients referred for suspected NCGS, while the remaining 93% would be confirmed as NCGS; this is not yet universally adopted.For people on a gluten-free diet who are unable to perform an oral gluten challenge, an alternative to identify possible celiac disease is an in vitro gliadin challenge of small bowel biopsies, but this test is only available at selected specialized tertiary-care centers. Treatment
After exclusion of celiac disease and wheat allergy, the subsequent step for diagnosis and treatment of NCGS is to start a strict gluten-free diet (GFD) to assess if symptoms improve or resolve completely. This may occur within days to weeks of starting a GFD, but improvement may also be due to a non-specific, placebo response. The recovery of the nervous system is slow and sometimes incomplete.Recommendations may resemble those for celiac disease, for the diet to be strict and maintained, with no transgression. The degree of gluten cross contamination tolerated by people with NCGS is not clear but there is some evidence that they can present with symptoms even after consumption of small amounts.
At that time, most construction trades and industries were unaware of the potential risks associated with beryllium exposure.It occasionally killed early workers in nuclear weapons design, such as Herbert L. Anderson.Beryllium sensitivity testing was first performed as a cutaneous beryllium patch test in the early 1950s, but was discontinued due to the test stimulating sensitization or aggravating existing chronic beryllium disease. : 115 In the 1990s, the DOE began screening employees using the BeLPT test in facilities where beryllium was used, in order to take preventive measures against beryllium exposure; somewhat alarmingly, clerical staff who were never involved in handling the material had developed asymptomatic sensitivities.The 1954 Isaac Asimov short story "Sucker Bait" is largely concerned with a space colony dying of Beryllium poisoning.
