Test purchasing of same day and rapid online alcohol home delivery in two Australian jurisdictions.

OBJECTIVE: With same day online alcohol sales increasing, there is a need to study their regulation. Test purchasing of alcohol home delivery was conducted to measure compliance with regulations for identification checks and unattended deliveries in two Australian jurisdictions (Perth, Western Australia and Geelong, Victoria), which have differing regulations. METHOD: Alcohol orders for same day or rapid (<2 hours) delivery on Friday and Saturday nights were made by research assistants aged 18-24 years in Perth (n=34) and Geelong (n=29). An observation checklist was used to record the delivery interaction, with a specific focus on checking of photo identification at time of delivery and whether deliveries were left unattended. RESULTS: Average time from order to delivery for rapid deliveries was less than one hour in both sites (Perth = 50 minutes; Geelong = 36 minutes). More than 20% of deliveries were made without an identification check in both sites (Perth = 24%; Geelong = 21%). CONCLUSIONS: This pilot study showed alcohol can be delivered to the home within one hour, and not all deliveries include an identification check at point of delivery. These findings indicate a need for policies that empower regulators and police to undertake 'mystery shopper' monitoring to reduce potential harms and improve compliance with alcohol delivery policy.

Degradation Therapy with Collagenase and Deoxycholate.

Deoxycholate (deoxycholic acid) and collagenase are naturally occurring substances whose ability to degrade adipose tissue and collagen respectively has given rise to a variety of therapeutic applications. This article will discuss the indications for the use of deoxycholic acid, primarily its well-established role in the non-surgical reduction of submental fat, with a focus on patient assessment, procedural technique, risks, pitfalls, and key clinical tips. It will also review the indications for collagenase as a degradation therapy, its mechanism of action, and benefits in the management of wound healing, scarring, and adipose tissue modification.

Setting research priorities for management and treatment of hyperhidrosis: the results of the James Lind Alliance Priority Setting Partnership.

BACKGROUND: Hyperhidrosis is a common skin condition characterized by excessive sweating, which can negatively impact on quality of life. It is under-researched compared with other conditions of similar prevalence. AIM: To generate a Top 10 list of research priorities for the treatment and management of hyperhidrosis, with equal input from people with hyperhidrosis and healthcare professionals (HCPs). METHODS: A priority setting partnership (PSP) was established and processes from the James Lind Alliance Handbook were followed. An online survey asked participants what questions they would like research to answer. These questions were grouped into 'indicative questions', which were ranked in a second survey of 45 indicative questions. The top 23 questions were then taken to a final workshop event attended by key stakeholders, and ranked to generate the Top 10 list of research priorities. RESULTS: There were 592 questions submitted by 268 respondents for the first survey. For the second survey, 286 participants ranked the indicative questions in order of priority. At the final workshop, the Top 10 list was generated. The top three priorities were: (i) Are there any safe and effective permanent solutions for hyperhidrosis? (ii) What is the most effective and safe oral treatment (drugs taken by mouth) for hyperhidrosis? and (iii) What are the most effective and safe ways to reduce sweating in particular areas of the body? CONCLUSIONS: There are many unanswered research questions that both people with hyperhidrosis and HCPs would like to see answered. The results from this PSP will help to ensure future research funding can be directed to these areas of priority.

Scalp ulceration: a rare manifestation of giant cell arteritis.

An 81-year-old woman presented with an enlarging, tender ulcer on her scalp over an 8-week period, attributing it to a prior graze with garden shears. C-reactive protein and erythrocyte sedimentation rate were elevated at 87.7 mg/L and 112 mm/hour, respectively. Incisional biopsies demonstrated ulceration and full thickness necrosis with no evidence of malignancy. Vasculitis was suggested as a likely cause of such extensive necrosis and subsequent temporal artery biopsy findings were consistent with giant cell arteritis. The patient was initially treated with high-dose oral prednisolone and achieved complete healing of the scalp necrosis within 12 months, with a gradual down-titration of steroid therapy thereafter. Scalp necrosis is a rare, potentially life-threatening complication of giant cell arteritis. This case highlights the importance of considering scalp necrosis as a manifestation of giant cell arteritis when assessing scalp ulceration. Prompt diagnosis and treatment can prevent significant morbidity and potential mortality.

Motivational Modulation of Self-Initiated and Externally Triggered Movement Speed Induced by Threat of Shock: Experimental Evidence for Paradoxical Kinesis in Parkinson's Disease.

BACKGROUND: Paradoxical kinesis has been observed in bradykinetic people with Parkinson's disease. Paradoxical kinesis occurs in situations where an individual is strongly motivated or influenced by relevant external cues. Our aim was to induce paradoxical kinesis in the laboratory. We tested whether the motivation of avoiding a mild electric shock was sufficient to induce paradoxical kinesis in externally-triggered and self-initiated conditions in people with Parkinson's disease tested on medication and in age-matched controls. METHODS: Participants completed a shock avoidance behavioural paradigm in which half of the trials could result in a mild electric shock if the participant did not move fast enough. Half of the trials of each type were self-initiated and half were externally-triggered. The criterion for avoiding shock was a maximum movement time, adjusted according to each participant's performance on previous trials using a staircase tracking procedure. RESULTS: On trials with threat of shock, both patients with Parkinson's disease and controls had faster movement times compared to no potential shock trials, in both self-initiated and externally-triggered conditions. The magnitude of improvement of movement time from no potential shock to potential shock trials was positively correlated with anxiety ratings. CONCLUSIONS: When motivated to avoid mild electric shock, patients with Parkinson's disease, similar to healthy controls, showed significant speeding of movement execution. This was observed in both self-initiated and externally-triggered versions of the task. Nevertheless, in the ET condition the improvement of reaction times induced by motivation to avoid shocks was greater for the PD patients than controls, highlighting the value of external cues for movement initiation in PD patients. The magnitude of improvement from the no potential shock to the potential shock trials was associated with the threat-induced anxiety. This demonstration of paradoxical kinesis in the laboratory under both self-initiated and externally-triggered conditions has implications for motivational and attentional enhancement of movement speed in Parkinson's disease.

A randomized controlled pilot study to evaluate a technology platform for the assisted living of people with dementia and their carers.

The use of telemedicine is becoming increasingly popular in assisting with the home management of People with Dementia (PwD) by offering services to the carers that may enhance their ability to care for their relative for longer. A computerized platform, ALADDIN, was evaluated in its usefulness to reduce carer burden and distress and to improve their quality of life, in an attempt to delay institutionalization of PwD. ALADDIN offers educational material about dementia to carers and provides the opportunity to contact other carers and clinicians. ALADDIN also facilitates remote monitoring of the PwD and their carers by the clinicians to enable speedy delivery of appropriate intervention. The ALADDIN platform was piloted at three European sites, and used by thirty carers of PwD living in the community (platform group). The platform group and a control group of thirty PwD and their carers were assessed at baseline, 3 months, and 6 months. The results showed a significant improvement in the quality of life of the carers in the platform group, with some reduction in carer burden and distress. The platform was useful in monitoring the patients and facilitating contact with other professionals. Access to and use of the ALADDIN platform was rated positively by carers and clinicians. The ALADDIN platform's usefulness and applicability for prolonging the home management of PwD are discussed.

When the cats are away: the impact of sporting events on assault- and alcohol-related emergency department attendances.

INTRODUCTION AND AIMS: Despite the attention given to the broad topic of alcohol and violence, there are few studies of this relationship in the context of sporting events and their impact on alcohol-related hospital emergency department (ED) attendances, none of which are Australian. METHODS: De-identified patient records from Barwon Health's Geelong Hospital ED were analysed from 1 July 2005 to 16 February 2010. Information contained in these records included age, gender, suburb of residence, attendance date and time, arrival mode and reason for attendance. The ED triage database was searched for attendances relating to alcohol, drugs and assault of which 16,940 cases were returned. RESULTS: There was a substantial increase in annual alcohol-related ED attendances from 2006 to 2009. Hierarchical binary logistic regression analyses showed that having a game on a particular day did not contribute to the model, but there were significantly more ED attendances for assaults on days when the Geelong Cats won. There were no significant predictors of ED attendance for alcohol-related harm in the variables studied. DISCUSSION: The findings of the study suggest that there are significantly more assault-related attendances at the ED in Geelong when the local national football team, the Geelong Cats, won. None of the variables under investigation appears to have impacted on alcohol-related attendances which were not assaults (i.e. injuries or intoxication). CONCLUSIONS: It appears that increases in ED attendances associated with the success of a local sporting team are not significantly associated with alcohol use and are more influenced by other factors.

Deep brain stimulation of the subthalamic nucleus improves sense of well-being in Parkinson's disease.

Deep brain stimulation of the subthalamic nucleus is an effective treatment for the motor symptoms of Parkinson's disease. Although a range of psychiatric and behavioral problems have been documented following deep brain stimulation, the short-term effects of subthalamic nucleus stimulation on patients' mood have only been investigated in a few studies. Our aim was to compare self-reported mood in Parkinson's patients with deep brain stimulation of the subthalamic nucleus ON versus OFF. Twenty-three Parkinson's patients with bilateral deep brain stimulation of the subthalamic nucleus and 11 unoperated Parkinson's patients completed a mood visual analogue scale twice. Operated patients were tested with deep brain stimulation of the subthalamic nucleus both ON and OFF. All were assessed on medication. The operated Parkinson's group reported feeling significantly better coordinated, stronger, and more contented with deep brain stimulation ON compared to OFF. Fourteen of the 16 mood scales changed in a positive direction when deep brain stimulation of the subthalamic nucleus was ON. When changes in motor scores were taken into account, the operated patients still reported feeling better-coordinated, but also less gregarious with stimulation ON. Unoperated Parkinson's patients showed no differences on any of these measures between their 2 ratings. Short-term changes in deep brain stimulation of the subthalamic nucleus have a small and mostly positive effect on mood, which may be partly related to improvements in motor symptoms. The implications for day-to-day management of patients with deep brain stimulation of the subthalamic nucleus are discussed.

Effects of an endothelin receptor antagonist on a model of hypertensive retinopathy.

Hypertensive retinopathy manifests itself as progressive retinal microvascular pathology in response to aberrant blood flow. The current study sought to evaluate whether dysfunction of the vasoactive endothelin-1 (ET-1) system is involved in the pathogenesis of hypertension-induced retinopathy in an animal model of systemic hypertension. The endothelin receptor antagonist, bosentan, was administered to spontaneously hypertensive rats (SHRs) and comparisons were made with untreated SHRs and normotensive Wistar Kyoto (WKY) rats. The retinal mRNA expression of ET-1, ET-converting enzyme-1, ET(A) and ET(B) receptors and the basement membrane proteins, laminin beta1, collagen IV and fibronectin was quantified using real-time RT-PCR. In addition, retinal arteriole and/or capillary bed damage was assessed by qualitative and quantitative microscopy. mRNA for the ET(A) receptor was increased in SHRs, when compared to WKY control animals (p < 0.001). Treatment with bosentan in SHRs significantly reduced the expression of ET-1 (p < 0.05), and both the ET(A) (p < 0.0001) and ET(B) (p < 0.05) receptor subtypes. The laminin beta1, collagen IV and fibronectin mRNA expression was significantly higher in SHRs when compared to WKY control animals (p < 0.001). Treatment with bosentan abolished these responses and also the appearance of various microvascular lesions. ET-mediated vasoregulation abnormalities in the retinal microvasculature could play an associative role in lesion formation during hypertensive retinopathy.

The mouse beam walking assay offers improved sensitivity over the mouse rotarod in determining motor coordination deficits induced by benzodiazepines.

The mouse rotarod test of motor coordination/sedation is commonly used to predict clinical sedation caused by novel drugs. However, past experience suggests that it lacks the desired degree of sensitivity to be predictive of effects in humans. For example, the benzodiazepine, bretazenil, showed little impairment of mouse rotarod performance, but marked sedation in humans. The aim of the present study was to assess whether the mouse beam walking assay demonstrates: (i) an increased sensitivity over the rotarod and (ii) an increased ability to predict clinically sedative doses of benzodiazepines. The study compared the effects of the full benzodiazepine agonists, diazepam and lorazepam, and the partial agonist, bretazenil, on the mouse rotarod and beam walking assays. Diazepam and lorazepam significantly impaired rotarod performance, although relatively high GABA-A receptor occupancy was required (72% and 93%, respectively), whereas beam walking performance was significantly affected at approximately 30% receptor occupancy. Bretazenil produced significant deficits at 90% and 53% receptor occupancy on the rotarod and beam walking assays, respectively. The results suggest that the mouse beam walking assay is a more sensitive tool for determining benzodiazepine-induced motor coordination deficits than the rotarod. Furthermore, the GABA-A receptor occupancy values at which significant deficits were determined in the beam walking assay are comparable with those observed in clinical positron emission tomography studies using sedative doses of benzodiazepines. These data suggest that the beam walking assay may be able to more accurately predict the clinically sedative doses of novel benzodiazepine-like drugs.

The pathology of oral cancer.

Oral cancer is a serious public health problem, with over 200,000 new cases reported annually worldwide, two-thirds of which occur in developing countries. The overall mortality rate for intra-oral cancer remains high at approximately 50%, even with modern medical services, probably due to the advanced stage of the disease at presentation. This review outlines recent advances in our understanding of the roles and interactions of major risk factors for oral cancer worldwide, notably tobacco, alcohol and betel quid and the genetic polymorphisms determining their metabolism that may predispose patients to oral carcinoma. Oral epithelial lesions with malignant potential are described. We discuss the histopathology of oral cancer, its grading and the staging of the disease at clinical, microscopic, immunohistological and molecular levels. A recommended minimum dataset for pathology reports is described. The available strategies and current prospects for controlling oral cancer in the community are summarised.
