Nurse competence in the interface between primary and tertiary healthcare services.

Aims: (a) To explore nurses' self-assessed competence and perceived need for more training in primary and tertiary healthcare services; and (b) to investigate the factors associated with these issues.

Design: Quantitative, cross-sectional, descriptive.

Methods: The ProffNurseSAS, the Job Satisfaction Scale and socio-demographics were used.

Debating the use of work-based learning and interprofessional education in promoting collaborative practice in primary care: a discussion paper.

Background: The context of primary care in the UK is changing rapidly, underpinned by continuing policy drivers to ensure person-centred safe and effective practice. Undergraduate and postgraduate programmes for healthcare practitioners are increasingly using interprofessional education (IPE) as one route to engender greater understanding of others' roles and contributions to health care, with the suggestion that IPE leads to better integration and teamwork, and thus stronger collaborative practice. Access to education and professional development for those working in primary care is difficult, and individuals need the focus of learning to be clearly relevant to their practice.

Establishing the contribution of nursing in the community to the health of the people of Scotland: integrative literature review.

Aim: This paper is a report of an integrative literature review to explore the evidence base for nursing in the community.

Background: The Scottish Executive (2005) in Scotland (UK), announced that a review of nursing in the community should be undertaken to inform implementation of the policy Delivering for Health. This policy called for a fundamental shift in the focus of care away from acute hospitals into the community where health care in the future will be concentrated.

Advanced nursing practice: an introduction to physical assessment.

Changing philosophies of clinical management and moves to reduce junior doctors' hours have led to increasing pressure upon nurses to take on the responsibility for assessing and initiating the management of acutely ill patients. Although nurses have been educated to assess, plan, and deliver care in a format known as the nursing process, this does not fully equip them for the demands of their rapidly developing roles. With increased responsibility comes the risk of increased stress and legal accountability, particularly where inadequate support is provided.

Artificial ventilation in the prone position.

Turning a ventilated patient into the prone position can greatly enhance arterial blood oxygenation independent of ventilator parameters. This article explores the physiology relating to pulmonary ventilation, highlighting an overall improvement in ventilation/perfusion matching as a result of the prone position. A series of small studies seems to suggest that prone positioning can have a dramatic effect on life-threatening hypoxia, including adult respiratory distress syndrome (ARDS) but as yet there have been no large, randomised, multi-centre trials to put beyond doubt the benefits of prone ventilation.

Sternotomy infection with Mycoplasma hominis: a cause of "culture negative" wound infection.

Wound infections with Mycoplasma species are unusual; diagnosis may be delayed because of the growth characteristics of this organism. We report Mycoplasma hominis infection of sternotomy wounds in two patients. The first presented with fever and drainage from the incision 1 week after coronary artery bypass grafting.

Aberrant Histoplasma capsulatum. Confirmation of identity by a chemiluminescence-labeled DNA probe.

A cottony, light tan, filamentous fungus with pear-shaped microconidia and lacking tuberculated macroconidia was isolated from a bronchial lavage specimen. Subculture on several media at 37 degrees C failed to convert the fungus to a yeast form after several weeks; attempts at in vivo conversion in mice were also unsuccessful. Sera obtained several months apart showed M bands with Histoplasma capsulatum (HC) antigen by immunodiffusion and an increase in complement fixation titers with mycelial and yeast phase antigens of HC.

Comparison of vidas Clostridium difficile toxin-A assay and premier C. difficile toxin-A assay to cytotoxin-B tissue culture assay for the detection of toxins of C. difficile.

Damage to the intestinal mucosa by Clostridium difficile (CD) is toxin mediated. Two enzyme immunoassays (EIAs) for toxin-A detection, the automated Vitek immunodiagnostic assay system CDA (Vidas CDA), and the Premier toxin A (Premier) were tested for their ability to detect toxin A in 301 stool samples and compared with an in-house tissue culture assay for toxin B (TCA). Of these 301 samples, 49 were TCA positive and 252 were TCA negative.

Comparison of the Vitek Immunodiagnostic Assay System with an indirect immunoassay (Toxostat Test Kit) for detection of immunoglobulin G antibodies to Toxoplasma gondii in clinical specimens.

The value and convenience of testing for specific anti-Toxoplasma gondii antibodies have led to the development of various antibody detection methods, such as the enzyme immunoassay. Two enzyme immunoassays, the Vitek Immuno-Diagnostic Assay System (VIDAS; Vitek Systems, Hazelwood, Mo.) and the Toxostat Test Kit (TST; Whittaker Bioproducts, Walkersville, Md.

Corneal microsporidioses: characterization and identification.

Two ocular infectious disorders attributed to Microsporidia have been observed. They differ in that one infection involves the corneal stroma leading to corneal ulceration and suppurative keratitis whereas the other infection involves the conjunctival and corneal epithelium. The corneal stromal infection is caused by a binucleated oval spore that is Nosema-like in character.

Corneal microsporidiosis in a patient with AIDS.

Microsporidia are obligate intracellular protozoan parasites that are becoming increasingly recognized as opportunistic pathogens in patients with AIDS. They have been associated with enteritis, hepatitis, and peritonitis and recently keratoconjunctivitis. Gram stain demonstrates the presence of these organisms on light microscopic sections.

Acanthamoeba and disinfection of soft contact lenses.

The association between acanthamoeba keratitis and the use of soft contact lenses is firmly established. Despite alerts and warnings, education of eye-care professionals and patients, and identification of risk factors that are associated with the use of soft contact lenses, acanthamoeba keratitis remains a threat. It is presumed that in some cases, the soft contact lens is the vector by which Acanthamoeba is introduced to the cornea.

Rapid identification of Staphylococcus epidermidis.

A panel of Minitek sugar disks, consisting of trehalose, mannitol, xylose, and sucrose, was evaluated for its ability to identify blood culture isolates of Staphylococcus epidermidis (SE). Using a heavy suspension of organism in Mueller-Hinton broth, 50 microL was pipetted onto each disk in wells of a flat-bottomed microtiter tray. The tray was covered, incubated in a moist chamber in non-CO2 at 35 degrees C, and examined after 5 and 24 hours.

Electrically evoked contractions of the triceps surae during and following 21 days of voluntary leg immobilization.

The effects of 21 days voluntary leg (plaster) immobilization on the mechanical properties of the triceps surae have been studied in 11 young female subjects, mean age 19.4 years. The results show that during the period of immobilization the mean time to peak tension (TPT) and half relaxation time (1/2RT) and tension (Pt) of the maximal twitch increased significantly (p less than 0.

Detection of methicillin-resistant Staphylococcus epidermidis.

To determine whether methods suggested for detecting methicillin-resistant Staphylococcus aureus apply equally to methicillin-resistant Staphylococcus epidermidis, 135 S. epidermidis isolates were tested by the Vitek AMS gram-positive susceptibility card (Vitek Systems, Inc., Hazelwood, Mo.

Predictive value of serologic tests for syphilis in otology.

Otologic syphilis (luetic inner ear disease) usually is diagnosed by positive serologic tests and by exclusion of other possible causes. Because the FTA-ABS for syphilis is exquisitely sensitive in all but early primary cases, a positive FTA-ABS result and coincident inner ear disease often are thought to be diagnostic of syphilitic inner ear disease. The result is a management dilemma: are there false-positive results in misdiagnosed cases? Over 4 years, the authors performed a prospective study with time-matched controls to determine the predictive value of serologic tests and prevalence of syphilis in otology.

Susceptibility of Acanthamoeba to soft contact lens disinfection systems.

Members of the genus Acanthamoeba are increasingly recognized as agents of indolent, chronic, infectious keratitis. Recently, Acanthamoeba corneal infection has been reported in some persons who wear soft contact lenses. In this study, three "heat" and three "cold" soft contact lens disinfection systems were tested according to the manufacturers' instructions against Acanthamoeba castellanii and Acanthamoeba polyphaga in separate trials, and with appropriate controls.

Susceptibility of Acanthamoeba to cryotherapeutic method.

Acanthamoeba keratitis is becoming an increasingly well-known clinical entity. The Acanthamoeba species in their encysted state are resistant to antimicrobial agents, resulting in corneal infections that are refractory to medical therapy. Corneal cryotherapy has been used to treat Acanthamoeba keratitis with varying and equivocal success.
