ABSTRACT

Vertigo is a common cause of emergency department attendance. Detection of spontaneous nystagmus may be a useful sign in distinguishing vestibular neuritis from other vestibular diagnoses. We aimed to assess the contribution of spontaneous nystagmus in the diagnosis of acute vertigo. We enrolled consecutive consenting patients arriving at a single emergency department with acute vertigo. There was no declared protocol for the emergency department staff. A standardized history and examination was conducted by the investigators. Observation for spontaneous nystagmus, its response to visual fixation, and testing the vestibulo-ocular reflex with the horizontal head impulse test were the chief examination components. MRI was obtained within 24 hours. Clinical criteria and MRI were used to reach the final diagnosis. The investigators' physical findings and final neurological diagnosis were compared with the initial emergency department examination findings and the referral diagnosis. There were 28 patients, 15 with vestibular neuritis, six with benign paroxysmal positional vertigo, one with stroke, suspected clinically, and three with migraine. In three the diagnosis remained uncertain. Spontaneous nystagmus was seen in all 15 patients with vestibular neuritis, fixation-suppressed in eight of 11 tested for this. The head impulse test was positive in 12 of 15 with vestibular neuritis. The emergency department referral diagnosis was correct in six of 23 patients. The ability to detect spontaneous nystagmus is useful in vestibular diagnosis, both in support of a diagnosis of vestibular neuritis and in avoiding false positive diagnoses of benign paroxysmal positional vertigo.

ABSTRACT

OBJECTIVES: To report the burden and cost of actinic keratosis (AK) treatment in Australia and to forecast the number of AK treatments and the associated costs to 2020. DESIGN AND SETTING: A retrospective study of data obtained from medicare Australia for AK treated by cryotherapy between 1 January 1994 and 31 December 2012, by year and by state or territory. RESULTS: The total number of AK cryotherapy treatments increased from 247,515 in 1994 to 643,622 in 2012, and we estimate that the number of treatments will increase to 831,952 (95% CI 676,919 to 986,987) by 202. The total Medicare Benefits Schedule (MBS) benefits paid out for AK in 2012 was $19.6 million and we forecast that this will increase to $24.7 million by 2020 (without inflation). CONCLUSION: The number of AK cryotherapy treatments increased by 160% between 1994 and 2012. we forecast that the number of treatments will increase by 30% between 2012 and 2020. The rates of non-melanoma skin cancer (NMSC) and AK appear to be increasing at the same rate. During the period 2010 to 2015 AK is anticipated to increase by 17.8% which follows a similar trend to published data that forecasts an increase in NMSC treatments of 22.3%.

ABSTRACT

BACKGROUND: Carers provide extended and often unrecognized support to people with cancer. The aim of this study is to test the hypothesis that excessive carer burden is modifiable through a telephone outcall intervention that includes supportive care, information and referral to appropriate psycho-social services. Secondary aims include estimation of changes in psychological health and quality of life. The study will determine whether the intervention reduces unmet needs among patient dyads. A formal economic program will also be conducted. METHODS/DESIGN: This study is a single-blind, multi-centre, randomized controlled trial to determine the efficacy and cost-efficacy of a telephone outcall program among carers of newly diagnosed cancer patients. A total of 230 carer/patient dyads will be recruited into the study; following written consent, carers will be randomly allocated to either the outcall intervention program (n = 115) or to a minimal outcall / attention control service (n = 115). Carer assessments will occur at baseline, at one and six months post-intervention. The primary outcome is change in carer burden; the secondary outcomes are change in carer depression, quality of life, health literacy and unmet needs. The trial patients will be assessed at baseline and one month post-intervention to determine depression levels and unmet needs. The economic analysis will include perspectives of both the health care sector and broader society and comprise a cost-consequences analysis where all outcomes will be compared to costs. DISCUSSION: This study will contribute to our understanding on the potential impact of a telephone outcall program on carer burden and provide new evidence on an approach for improving the wellbeing of carers.

ABSTRACT

OBJECTIVES: To present the outcomes of men undergoing artificial urinary sphincter (AUS) implantation. To determine the impact a history of radiation therapy has on the outcomes of prosthetic surgery for stress urinary incontinence. PATIENTS AND METHODS: A cohort of 77 consecutive men undergoing AUS implantation for stress urinary incontinence after prostate cancer surgery, including 29 who had also been irradiated, were included in a prospective database and followed up for a mean period of 21.2 months. Continence rates and incidence of complications, revision and cuff erosion were evaluated, with results in irradiated men compared with those of men who had undergone radical prostatectomy alone. The effect of co-existing hypertension, diabetes mellitus and surgical approach on outcomes were also examined. RESULTS: Overall, the rate of social continence (0-1 pad/day) was 87% and similar in irradiated and non-irradiated men (86.2 vs 87.5%). Likewise, the incidence of infection (3.4 vs 0%), erosion (3.4 vs 2.0%) and revision surgery (10.3 vs 12.5%) were not significantly different between the groups. There was a far greater incidence of co-existing urethral stricture disease in irradiated patients (62.1 vs 10.4%) which often complicated management; however, AUS implantation was still feasible in these men and, in four such cases, a transcorporal cuff placement was used. There were poorer outcomes in patients with diabetes, and a greater re-operation rate in those men who underwent a transverse scrotal rather than perineal surgical approach, although the differences did not reach statistical significance. CONCLUSIONS: Previous irradiation in patients may increase the complexity of treatment because of a greater incidence of co-existing urethral stricture disease; however, these patients are still able to achieve a level of social continence similar to that of non-irradiated patients, with no discernable increase in complication rates, cuff erosion or the need for revision surgery. AUS implantation remains the 'gold standard' for management of moderate-to-severe stress urinary incontinence in both irradiated and non-irradiated patients after prostate cancer treatment.
