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.

Review Case ReportsPyogenic liver abscess with a focus on Klebsiella pneumoniae as a primary pathogen: an emerging disease with unique clinical characteristics.
Pyogenic liver abscess is a common intraabdominal infection. Historically, Escherichia coli (E. coli) has been the predominant causative agent. Klebsiella liver abscess (KLA) was first reported in Taiwan and has surpassed E. coli as the number one isolate from patients with hepatic abscesses in that country and reports from other countries, including the United States, have increased. We examined the microbiologic trends of pyogenic liver abscess at our institution to determine if a similar shift in etiologic agents was occurring. ⋯ These data suggest that KLA may represent an emerging disease in Western countries, such as the United States. The diagnosis of K. pneumoniae should be considered in all cases of liver abscess, and appropriate antibiotic therapy and a diagnostic work-up for metastatic complications should be employed.

ReviewHepatorenal syndrome: a dreaded complication of end-stage liver disease.
Hepatorenal syndrome is the dreaded complication of end-stage liver disease characterized by functional renal failure due to renal vasoconstriction in the absence of underlying kidney pathology. The pathogenesis of hepatorenal syndrome is the result of an extreme underfilling of the arterial circulation secondary to an arterial vasodilation located in the splanchnic circulation. This underfilling triggers a compensatory response with activation of vasoconstrictor systems leading to intense renal vasoconstriction. ⋯ Pharmacological therapies based on the use of vasoconstrictor drugs (terlipressin, midodrine, octreotide, or noradrenline) are the most promising in the aim of successfully offering a bridge to liver transplantation. Other treatments such as transjugular intrahepatic portosystemic shunts and albumin dialysis are effective but experience is very limited. Although there is limited information on the prevention of hepatorenal syndrome, intravenous albumin infusion in patients with spontaneous bacterial peritonitis and with oral pentoxifylline in patients with acute alcoholic hepatitis seems to effectively prevent hepatorenal syndrome in these two settings.

Review Comparative StudyInformed consent: not just for procedures anymore.
The ethical and legal requirement to obtain informed consent prior to performing a procedure or administering a treatment derives from the concept of personal (patient) autonomy. The competent patient, after receiving appropriate disclosure of the material risks of the procedure or treatment, understanding those risks, the benefits, and the alternative approaches, makes a voluntary and uncoerced informed decision to proceed. ⋯ The benefits of informed decision making as a communication and risk management tool are presented. This review is intended as general information, and not as legal advice, which should be sought from a health-care attorney.
