Probable alcohol abuse or dependence: a risk factor for intensive-care readmission in patients undergoing elective vascular and thoracic surgical procedures. Mayo Perioperative Outcomes Group.
To determine whether alcohol abuse or dependence is a risk factor for perioperative complications, increased duration of hospital stay, and increased utilization of nursing resources in patients undergoing thoracic and vascular surgical procedures. ⋯ Except for the occurrence of alcohol withdrawal syndrome, study patients classified in the probable alcohol abuse group did not have more medical or surgical perioperative complications than patients in the nonalcoholic group. They did have significantly more intensive-care setting readmissions. Patients with documented alcohol withdrawal episodes frequently were dismissed without a diagnosis of substance abuse or dependence.

Potential effect of authorization bias on medical record research.
To analyze the influence of recent changes in Minnesota statutes that generally require prior authorization for use of medical records for research from patients who received medical care after Jan. 1, 1997. ⋯ These data demonstrate that laws requiring written authorization for research use of the medical record could result in substantial biases in etiologic and outcome studies, the direction and magnitude of which may vary from topic to topic. Clinicians should be prepared to enter the discussion to help inform patients and legislators of the potential hazards of laws that restrict access to medical records for research purposes.

ReviewCarbapenems and monobactams: imipenem, meropenem, and aztreonam.
Imipenem and meropenem, members of the carbapenem class of beta-lactam antibiotics, are among the most broadly active antibiotics available for systemic use in humans. They are active against streptococci, methicillin-sensitive staphylococci, Neisseria, Haemophilus, anaerobes, and the common aerobic gram-negative nosocomial pathogens including Pseudomonas. Resistance to imipenem and meropenem may emerge during treatment of P. aeruginosa infections, as has occurred with other beta-lactam agents; Stenotrophomonas maltophilia is typically resistant to both imipenem and meropenem. ⋯ It is often used in combination therapy for mixed aerobic and anaerobic infections. Approved indications for its use include infections of the urinary tract or lower respiratory tract, intra-abdominal and gynecologic infections, septicemia, and cutaneous infections caused by susceptible organisms. Concurrent initial therapy with other antimicrobial agents is recommended before the causative organism has been determined in patients who are seriously ill or at risk for gram-positive or anaerobic infection.

ReviewEmerging concepts in the neurobiology of chronic pain: evidence of abnormal sensory processing in fibromyalgia.
Chronic pain often differs from acute pain. The correlation between tissue pathology and the perceived severity of the chronic pain experience is poor or even absent. Furthermore, the sharp spatial localization of acute pain is not a feature of chronic pain; chronic pain is more diffuse and often spreads to areas beyond the original site. ⋯ During the past decade, an exponential growth has occurred in the scientific underpinnings of chronic pain states. In particular, the concept of nonnociceptive pain has been refined at a physiologic, structural, and molecular level. This review focuses on this new body of knowledge, with particular reference to the chronic pain state termed "fibromyalgia."

Comparative StudyType 1 diabetes mellitus in early childhood: glycemic control and associated risk of hypoglycemic reactions.
To assess the level of glycemic control and to determine whether more normal glycemic control, as measured by glycosylated hemoglobin, leads to frequent hypoglycemic episodes in young patients with type 1 diabetes mellitus. ⋯ Tight glycemic control is achievable in young patients with type 1 diabetes mellitus. Such tight control, however, may lead to an increase in the frequency of severe hypoglycemic reactions in this patient population. Our data support the guideline that children younger than 5 years should have a higher goal for premeal plasma glucose levels.
