Do we need an intravenous fluoroquinolone?

Intravenous ciprofloxacin, the first parenteral fluoroquinolone available in this country, represents another class of antimicrobial agents from which physicians must choose when treating nosocomial infections. Fluoroquinolones are bactericidal antimicrobial agents that act by inhibiting DNA gyrase. They are active in vitro against most gram-negative bacteria and methicillin-susceptible staphylococci. Activity against anaerobic bacteria and streptococci is poor. The rapid development of bacterial resistance in centers with high quinolone usage is of great concern. Resistance develops most commonly in Pseudomonas aeruginosa and staphylococci. Resistance emerges most often when quinolones are used to treat chronic infections or in patients with poorly drained abscesses, necrotic tissue, or indwelling catheters. Clinical trials have shown ciprofloxacin to be as effective as ceftazidime in the treatment of infections caused by gram-negative bacteria. Although the overall frequency of side effects to fluoroquinolones is low, seizures and allergic reactions have been attributed to their use. Ciprofloxacin inhibits the metabolism of theophylline, and morbidity and death have been reported in patients taking the two drugs concomitantly. Parenteral fluoroquinolones should be reserved for the treatment of gram-negative bacterial infections in patients in whom standard agents cannot be used.

Mental imagery and its potential for physical therapy.

The purposes of this article are 1) to review the sports and motor-learning literature regarding the effects of mental imagery and mental practice on physical skills and 2) to explore the feasibility of using them as adjunctive techniques in physical therapy. In the area of sports, evidence exists that mental practice can improve motor skills. Research that supports a mind-body relationship is cited, in addition to research using mental imagery from the areas of medicine, biofeedback, psychoneuroimmunology, and physical therapy. Variables that influence the outcome of mental practice such as vividness, kinesthetic imagery, and combining physical and mental practice are examined, and two major variables associated with ineffective results are identified. The advantages and disadvantages of using mental imagery for physical therapy patients are discussed with the conclusion that mental imagery has the potential to be a viable technique for physical therapists.

Myopericarditis as an initial presentation of meningococcemia. Unusual manifestation of infection with serotype W135.

Acute meningococcemia is a dramatic clinical syndrome from infection with the gram-negative diplococcus, Neisseria meningitidis. Although pericarditis may complicate the course of meningococcemia, it is distinctly unusual as a presenting sign. A case of disseminated meningococcemia presenting as acute myopericarditis is reported. The serotype isolated, type W135, was a sporadic cause of N. meningitidis in the Boston area. Although the patient had meningitis, bacteremia, and myopericarditis, his course was uncomplicated with early institution of antibiotic therapy.

The MMPI, prototypal typology, and borderline personality disorder.

This study demonstrates inherent features in the DSM-III diagnostic criteria for personality disorders (i.e., overlapping diagnoses and heterogeneous symptomatology) that limit efforts to identify a sensitive and specific MMPI profile for the borderline personality disorder. A sample of 71 inpatients was administered an MMPI and a semistructured interview that systematically evaluated each of 81 symptoms for the 11 DSM-III personality disorders. Interrater reliability was substantially higher than has been obtained with unstructured interviews. The effect on the borderline MMPI profile of variation in the number of borderline symptoms and overlap with the schizotypal, histrionic, and antisocial diagnoses was demonstrated. We discuss implications with respect to a prototypal model of classification.
