Randomized Controlled Trial Clinical TrialInfusion of neostigmine-glycopyrrolate for bowel evacuation in persons with spinal cord injury.
Defecatory complications are common after spinal cord injury (SCI) and have been attributed, in part, to an imbalance of the autonomic nervous system between parasympathetic and sympathetic effects on the colon. Because parasympathetic (i.e., cholinergic) input to the bowel may be downregulated after SCI, it was hypothesized that neostigmine, a medication that increases cholinergic tone by blocking the metabolism of acetylcholine, might promote bowel evacuation in these persons. Since neostigmine is known to cause bradycardia and bronchoconstriction, we also assessed whether these side-effects could be prevented by coadministration of neostigmine with glycopyrrolate, an anticholinergic agent that has limited activity on the muscarinic receptors of the colon. ⋯ Other side-effects of neostigmine and the combination of drugs included muscle fasciculations and dry mouth, both of which were mild and short-lived. Abdominal cramping was noted in subjects with spinal cord lesions below thoracic level 10. These results indicated that neostigmine/glycopyrrolate administration is safe and well tolerated in persons with chronic SCI.

ReviewThe Health Insurance Portability and Accountability Act (HIPAA): its broad effect on practice.
The Health Insurance Portability and Accountability Act (HIPAA), and its final rule, raised fears among practitioners of new and complex regulations that might interfere with medical practice, lead to inadvertent liability and unwanted expense. It generated a dizzying set of health-care administrative activities and a new work for legal consultants. It has extensive scope, and includes most health plans and practitioners. ⋯ However, after a HIPAA compliant office structure is established, and the privacy notice is reviewed and signed by the patient, disclosure of medical information for treatment, payment or "health-care operations" is permitted without recurrent consent forms, thus allowing substantially familiar patterns of doctor-to-doctor communication about treatment. Further, the initial approach to enforcement appears to some legal observers to be more likely corrective rather than punitive, although providers remain uneasy over the mere possibility of criminal penalties. As regards medical research, uncertainties about the application of HIPAA seem less resolved and more variably interpreted by different institutions, with ongoing fear in the research community that important public health and epidemiologic research activity may be compromised by well meaning IRBs using inconsistent, overly strict or erroneous interpretation of the intent of HIPAA regulations.

The clinical value of procalcitonin in early assessment of acute pancreatitis.
Early assessment of the severity and the etiology is crucial in the management of acute pancreatitis. To determine the value of procalcitonin (PCT) as a prognostic marker and as an indicator of biliary etiology in the early phase of acute pancreatitis. ⋯ PCT is of limited additional value for early assessment of severity and etiology in acute pancreatitis. CRP is found to be a reliable prognostic marker with a delay of 48 h, while ALT is validated as the best indicator of biliary etiology.

A prospective study of gastric emptying and its relationship to the development of nausea, vomiting, and anorexia after autologous stem cell transplantation.
Gastric motor dysfunction may be responsible, in some patients, for the nausea and emesis that occur following high-dose chemotherapy (HDT) and autologous stem cell transplantation (SCT). We sought to define the prevalence of gastric emptying abnormalities and their relationship to the development of nausea, vomiting, and anorexia in patients undergoing HDT and autologous SCT. ⋯ Both delayed and rapid gastric emptying occur commonly during the 2-wk period following HDT and autologous SCT and may be responsible, at least in part, for upper gastrointestinal symptoms that occur in these patients.
