Amoebic encephalitis within Australia.

Granulomatous amoebic encephalitis is a rare but likely under-recognised form of subacute, usually fatal, encephalitis. We present an illustrative case report and literature review of Australian cases, summarising clinical features, diagnostic methods, treatment and outcomes.

Risk factors for nephrotoxicity in patients receiving outpatient continuous infusions of vancomycin in an Australian tertiary hospital.

OBJECTIVES: To assess the risk factors for nephrotoxicity caused by vancomycin continuous infusion in a predominantly Caucasian outpatient population. METHODS: This was a retrospective cohort study of 155 patient episodes from December 2006 to December 2011. RESULTS: Vancomycin-associated nephrotoxicity (VN) occurred in 26 of 155 (17%) patient episodes. After adjustment for baseline renal function, maximum steady-state vancomycin concentrations ≥32 mg/L [OR 8.7 (95% CI 3.1-29.6), P < 0.001] and angiotensin receptor blockade [OR 9.78 (95% CI 3.1-39.4), P < 0.001] were independently associated with VN. The cumulative dose and duration of vancomycin therapy were not independent predictors of VN. CONCLUSIONS: Cessation of angiotensin receptor-blocking medications in selected patient groups, enhanced monitoring and establishing target steady-state concentrations <30 mg/L to avoid excessive vancomycin exposure may reduce the risk of VN.

Can perpetrators discern survivors from voice?

Background: Research has shown that potential perpetrators and individuals high in psychopathic traits tend to body language cues to target a potential new victim. However, whether targeting occurs also by tending to vocal cues has not been examined. Thus, the role of voice in interpersonal violence merits investigation.Objective: In two studies, we examined whether perpetrators could differentiate female speakers with and without sexual and physical assault histories (presented as rating the degree of 'vulnerability' to victimization).Methods: Two samples of male listeners (sample one N = 105, sample two, N = 109) participated. Each sample rated 18 voices (9 survivors and 9 controls). Listener sample one heard spontaneous speech, and listener sample two heard the second sentence of a standardized passage. Listeners' self-reported psychopathic traits and history of previous perpetration were measured.Results: Across both samples, history of perpetration (but not psychopathy) predicted accuracy in distinguishing survivors of assault.Conclusions: These findings highlight the potential role of voice in prevention and intervention. Gaining a further understanding of what voice cues are associated with accuracy in discerning survivors can also help us understand whether or not specialized voice training could have a role in self-defense practices.

We examined whether listeners with history of perpetration could differentiate female speakers with and without assault histories (presented as rating the degree of 'vulnerability' to victimization).Listeners' higher history of perpetration was associated with higher accuracy in differentiating survivors of assault from non-survivors.These findings highlight that voice could have a crucial role in prevention and intervention.

Hospitalizations for pandemic (H1N1) 2009 among Maori and Pacific Islanders, New Zealand.

Community transmission of influenza A pandemic (H1N1) 2009 was followed by high rates of hospital admissions in the Wellington region of New Zealand, particularly among Maori and Pacific Islanders. These findings may help health authorities anticipate the effects of pandemic (H1N1) 2009 in other communities.

Is vitamin D testing at a tertiary referral hospital consistent with guideline recommendations?

To determine if 25 hydroxyvitamin D (25OHD) testing at our tertiary referral hospital is consistent with guideline recommendations concerning the clinical indications for testing, the timing of repeat testing and utilisation of the test result, we conducted a retrospective audit of electronic laboratory and patient case records. We included adult inpatients and outpatients who had serum 25OHD measured during a randomly selected one-week audit period and who had patient case records available for detailed review. The audit sample comprised 184 serum 25OHD measurements (134 initial and 50 repeat tests). There were 81 (60%) initial and 15 (30%) repeat tests [96 (52%) overall] that were consistent with guideline recommendations concerning clinical indication, timing of repeat testing and utilisation of result. Almost half the 25 hydroxyvitamin D tests audited were potentially unnecessary and/or not utilised clinically. Improved adherence to guideline recommendations for 25 hydroxyvitamin D testing, utilisation of test results and enforcement of new indications for testing due to be introduced by Medicare Australia could result in significant cost savings without adversely affecting patient outcomes.

Cardiac rehabilitation with nurse care management and telephonic interactions at a community hospital: program evaluation of participation and lipid outcomes.

Cardiac rehabilitation (CR) can help patients with heart disease control some risk factors, limit new coronary artery lesions, and decrease death rates. However, participation rates in CR are low. Using a descriptive design, we evaluated a modified CR program in which nurse care managers used telephonic communication with patients in their homes by comparing it to a traditional CR program in a hospital setting. Using multivariate analysis we compared the patient cohorts eligible for each of the programs, and program participants to the nonparticipants for each program. Compared to traditional CR, the modified CR program with nurse care management was associated with significantly improved participation rates (11% vs. 22%) and the apparent overcoming of several well-described barriers to CR participation (distance from the hospital and domestic isolation). Risk factor management, including testing of serum lipids and achieving goals for lipid reduction, for participants in both CR programs was superior to risk factor management for nonparticipants.

Pandemic influenza A(H1N1)2009 in hospital healthcare workers in New Zealand.

We evaluated A/H1N1 influenza in healthcare workers (HCWs) and in a flu room during the 2009 pandemic. The flu room aided HCW care and management by facilitating rapid diagnosis and treatment. Absence of fever was common, and symptoms were nonspecific. A higher rate of H1N1 occurred in HCWs deployed in acute services.
