The Balance Error Scoring System (BESS) is widely recognized as an acceptable assessment of postural control for adult patients following a mild traumatic brain injury (mTBI) or concussion. However, the measurement properties of the BESS as a post-mTBI assessment test for younger patients are not well understood. The purpose of this study was to evaluate the utility of the BESS as a post-mTBI assessment test for children and adolescents aged 8 to 18 years through 2 investigations: (1) a retrospective medical records review of the relationship among age, BESS scores, and other common post-mTBI assessment tests; and (2) a prospective study comparing BESS scores for a cohort of children with a recent mTBI and BESS scores for a cohort of matched healthy peers.

The patient received no diuretics, was not acidotic, and had a creatinine clearance of 39 ml/min. Insulin or pharmacologic doses of desoxycorticosterone acetate eliminated the glucose-induced hyperkalemia.

The enzymatic hydroxylation of biphenyl in the liver microsome fractions of rabbits, guinea pigs and rats has been studied. They hydroxylated biphenyls were detected by thin-layer and gas chromatography. By the aid of gas chromatography all the hydroxybiphenyls could be quantitatively determined simultaneously.

A further case of chronic ulcerative enteritis is presented. In this case there was clear evidence that the ulcerative process was superimposed upon atrophic jejunitis with malabsorption. The development of ulceration produced a picture of small bowel obstruction and its differential diagnosis from neoplasm was not possible without laparotomy.
