Exosomes are 40-100 nm intraluminal vesicles that are released by cells upon fusion of multivesicular endosomes (MVEs) with the plasma membrane. The Rab family of small GTPases, including Rab27A and Rab27B, control different steps of exosome release, including transport of MVEs and docking at the plasma membrane. Exosomes are long range message particles that mediate communication between cells in physiological conditions such as mammary gland development and lactation, but also in pathology such as breast cancer. Metastasis is the culmination of cancer progression and involves a complex interaction with the local and distant environment. Exosome messaging contributes to tumor environment interactions such as immune escape, thrombosis and myofibroblast differentiation, thereby modulating metastatic niche preparation. © 2011 UBC Press.

Purinergic signaling plays important roles in control of vascular tone and remodeling. There is dual control of vascular tone by ATP released as a cotransmitter with noradrenaline from perivascular sympathetic nerves to cause vasoconstriction via P2X1 receptors, whereas ATP released from endothelial cells in response to changes in blood flow (producing shear stress) or hypoxia acts on P2X and P2Y receptors on endothelial cells to produce nitric oxide and endothelium-derived hyperpolarizing factor, which dilates vessels. ATP is also released from sensory-motor nerves during antidromic reflex activity to produce relaxation of some blood vessels. In this review, we stress the differences in neural and endothelial factors in purinergic control of different blood vessels. The long-term (trophic) actions of purine and pyrimidine nucleosides and nucleotides in promoting migration and proliferation of both vascular smooth muscle and endothelial cells via P1 and P2Y receptors during angiogenesis and vessel remodeling during restenosis after angioplasty are described. The pathophysiology of blood vessels and therapeutic potential of purinergic agents in diseases, including hypertension, atherosclerosis, ischemia, thrombosis and stroke, diabetes, and migraine, is discussed. © 2013 by The American Society for Pharmacology and Experimental Therapeutics.

Purpose: Faecal incontinence is a common and important multifactorial disorder with a range of treatment options. Over the last two decades, neuromodulation via sacral nerve stimulators has been shown to be effective for both faecal and urinary incontinence, although associated with complications. Peripheral neuromodulation, via the posterior tibial nerve, is widely used in urinary incontinence; however, its use in faecal incontinence, whilst evolving is limited to eight small heterogeneous studies. Review: These eight studies are discussed in the context of the methodology and underlying neurophysiology of peripheral neuromodulation, as are thus far unanswered questions. The eight studies include a total of 129 patients with faecal incontinence (of variable aetiology), all of whom had failed conservative management. One study was prospective and controlled, six were uncontrolled and one was retrospective and uncontrolled. Five different neuro-modulatory protocols were used over six different study periods. Outcome measures varied, but short term primary endpoint success ranged from 30.0% to 83.3%. The limitations to this early evidence, whilst encouraging, are significant, and it remains to be seen whether this novel treatment modality represents the minimally invasive, well-tolerated, cost-effective and flexible panacea hoped for this common and debilitating disease. Three upcoming multi-centre placebo-controlled trials will better be able to delineate its role. © Springer-Verlag 2010.

Erosive lichen planus (ELP) affecting mucosal surfaces is a chronic autoimmune disease of unknown aetiology. It is often more painful and debilitating than the non-erosive types of lichen planus. Treatment is difficult and aimed at palliation rather than cure. Several topical and systemic agents have been used with varying results. To assess the effects of interventions in the treatment of erosive lichen planus affecting the oral, anogenital, and oesophageal regions. We searched the following databases up to September 2009: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE (from 2005), EMBASE (from 2007), and LILACS (from 1982). We also searched reference lists of articles and online trials registries for ongoing trials. We considered all randomised controlled trials (RCTs) that evaluated the effectiveness of any topical or systemic interventions for ELP affecting either the mouth, genital region, or both areas, in participants of any age, gender, or race. The primary outcome measures were as follows:(a) Pain reduction using a visual analogue scale rated by participants; (b) Physician Global Assessment; and (c) Participant global self-assessment.Changes in scores at the end of therapy compared with baseline were analysed. A total of 15 RCTs were identified, giving a total of 473 participants with ELP. All studies involved oral ELP only. Six of the 15 studies included participants with non-erosive lichen planus. In these studies, only the erosive subgroup was included for intended subgroup analysis. We were unable to pool data from any of the nine studies with only ELP participants or any of the six studies with the ELP subgroup, due to small numbers and the heterogeneity of the interventions, design methods, and outcome variables between studies. One small study involving 50 participants found that 0.025% clobetasol propionate administered as liquid microspheres significantly reduced pain compared to ointment (Mean difference (MD) -18.30, 95% confidence interval (CI) -28.57 to -8.03), but outcome data was only available in 45 participants. However, in another study, a significant difference in pain was seen in the small subgroup of 11 ELP participants, favouring ciclosporin solution over 0.1% triamcinolone acetonide in orabase (MD -1.40, 95% CI -1.86 to -0.94). Aloe vera gel was 6 times more likely to result in at least a 50% improvement in pain symptoms compared to placebo in a study involving 45 ELP participants (Risk ratio (RR) 6.16, 95% CI 2.35 to 16.13). In a study involving 20 ELP participants, 1% pimecrolimus cream was 7 times more likely to result in a strong improvement as rated by the Physician Global Assessment when compared to vehicle cream (RR 7.00, 95% CI 1.04 to 46.95).There is no overwhelming evidence for the efficacy of a single treatment, including topical steroids, which are the widely accepted first-line therapy for ELP. Several side-effects were reported, but none were serious. With topical corticosteroids, the main side-effects were oral candidiasis and dyspepsia. This review suggests that there is only weak evidence for the effectiveness of any of the treatments for oral ELP, whilst no evidence was found for genital ELP. More RCTs on a larger scale are needed in the oral and genital ELP populations. We suggest that future studies should have standardised outcome variables that are clinically important to affected individuals. We recommend the measurement of a clinical severity score and a participant-rated symptom score using agreed and validated severity scoring tools. We also recommend the development of a validated combined severity scoring tool for both oral and genital populations.

Obtaining informed consent is an essential process in the patient centred approach to modern medicine. However, research shows that patients have a poor understanding of the process of informed consent, as well as a poor understanding of the procedures they are consenting for. Improvements need to be made to improve comprehension and ensure that consent is truly valid.

Midwifery | Year: 2013
Objective: This paper explores perceptions of time and experience in midwifery with particular reference to the concept of early labour. Health professionals and lay people are used to describing labour in terms of 'stages' which correspond to agreed notions of progress based on physiological features. However the understanding of labour which underpins them is not a static entity but is a product of a particular era and set of circumstances which are primarily socially rather than biologically mediated. Design: The research uses a historical methodology to describe understanding of, and strategies around, the management of early labour. It includes a variety of source material, including midwifery and obstetric textbooks, midwifery casebooks, books of advice to women and the oral testimony of midwives and mothers. Setting: Twentieth century Britain. The twentieth century was a period of significant philosophical and concrete change in maternity in Britain, with occupational hegemony developing around both midwifery and obstetrics, and with the concomitant institutionalisation of labour and birth. Participants: Mothers, midwives and doctors. Findings: The evidence suggests that during the first half of the twentieth century early labour was not seen as a discrete period within the first stage of labour with specific features or associated issues. Instead it was a private and individual experience, which rarely involved the presence of either doctors or midwives. Women, and those around them, made the decision about what early labour meant and how they should respond to it. The development of divisions in labour and notions of what constituted 'normality' or 'abnormality' as regards the length of each stage, based on time and clinical features, developed as the setting for labour and birth moved from home to hospital in the second half of the twentieth century. Labour became more described and more proscribed, with a rash of textbooks aimed at both midwives and doctors, and with the growing visibility of the entire process of labour through the use of technological surveillance and through the fact that women labouring on a hospital bed were observable in a way that women labouring at home were not. Key conclusions and implications: To look for historical strategies around the management of entities such as early labour is to assume, ahistorically, that similar beliefs and issues existed in an earlier period, and that there perhaps existed strategies for management which could profitably be rediscovered for use in current maternity care. The evidence suggests that such divisions were not described or managed features of labour before the second half of the twentieth century. The use of history does, however, give insights into breaks and continuities in beliefs and practice over time, and demonstrates that beliefs about stages of labour and their management are, like other aspects of maternity, multi-faceted and complex in both origin and effect. © 2012 Elsevier Ltd.

Besides antitumor therapy for patients with the paraneoplastic form of Lambert-Eaton myasthenic syndrome (LEMS), the mainstay of symptomatic treatment in LEMS is 3,4-diaminopyridine (3,4-DAP). Data from four randomized, placebo-controlled trials have revealed that muscle strength scores increased significantly with 3,4-DAP. A limited meta-analysis performed on two trials using the Quantitative Myasthenia Gravis score indicated that the clinical benefits seen were modest. Meta-analysis of the mean change in compound muscle action potential amplitude following 3,4-DAP treatment revealed a significant improvement compared to placebo. However, most patients with noncancer LEMS require long-term immunosuppression, usually with prednisolone and azathioprine. A single crossover study has previously shown significant short-term benefit in limb strength following intravenous immunoglobulin, and there are isolated case reports of medium term benefit from rituximab. Overall, a combination of symptomatic treatment with 3,4-DAP and immunosuppression, with or without antitumor therapy, is often successful for most LEMS patients, with other more aggressive regimens rarely needed. © 2012 New York Academy of Sciences.

The success of incident reporting in improving safety, although obvious in aviation and other high-risk industries, is yet to be seen in health-care systems. An incident reporting system which would improve patient safety would allow front-end clinicians to have easy access for reporting an incident with an understanding that their report will be handled in a non-punitive manner, and that it will lead to enhanced learning regarding the causation of the incident and systemic changes which will prevent it from recurring. At present, significant problems remain with local and national incident reporting systems. These include fear of punitive action, poor safety culture in an organization, lack of understanding among clinicians about what should be reported, lack of awareness of how the reported incidents will be analysed, and how will the reports ultimately lead to changes which will improve patient safety. In particular, lack of systematic analysis of the reports and feedback directly to the clinicians are seen as major barriers to clinical engagement. In this review, robust systematic methodology of analysing incidents is discussed. This methodology is based on human factors model, and the learning paradigm which emphasizes significant shift from traditional judicial approach to understanding how 'latent errors' may play a role in a chain of events which can set up an 'active error' to occur. Feedback directly to the clinicians is extremely important for keeping them 'in the loop' for their continued engagement, and it should target different levels of analyses. In addition to high-level information on the types of incidents, the feedback should incorporate results of the analyses of active and latent factors. Finally, it should inform what actions, and at what level/stage, have been taken in response to the reported incidents. For this, local and national systems will be required to work in close cooperation, so that the lessons can be learnt and actions taken within an organization, and across organizations. In the UK, a recently introduced speciality-specific incident reporting system for anaesthesia aims to incorporate the elements of successful reporting system, as presented in this review, to achieve enhanced clinical engagement and improved patient safety. © The Author .

Purpose of review: To examine the place of surgery and other modes of treating scar tissue given the plethora of measures that are advocated on the internet. Recent findings: There is good evidence to support the use of silicone sheets, pulsed dye laser (PDL), intralesional triamcinolone and dermabrasion in reducing hypertrophic scars, but each needs qualifying in terms of their timing and the type of scar tissue that they are used for. Summary: The surgical revision of scars should be delayed for at least 12 months unless there is webbing when redistributing skin tension forces with a Z-plasty or multiple Z-plasties or other local flaps negates the need to wait for the scar to mature. In a posttraumatic 'horse shoe' shaped, or a very oblique, cut an irregular contour is likely to occur. Under these circumstances a triamcinolone injection into any raised area can help and this needs to be re-evaluated after 6 weeks. With a less irregular contour dermabrasion can help if used 8 weeks after surgery. With hypertrophic scarring both silicone gel sheeting and PDL may help reduce the prominence of the scar. Most of all time helps scars to settle and fade and typical scar maturation takes 18-24 months. The role of stem cells, particularly from adipose tissue, warrants further study. © 2010 Wolters Kluwer Health | Lippincott Williams and Wilkins.
