Antiviral treatment for Bell's palsy (idiopathic facial paralysis)

BACKGROUND: Antiviral agents against herpes simplex virus are widely used in the treatment of idiopathic facial paralysis (Bell's palsy), but their effectiveness is uncertain. Significant morbidity can be associated with severe cases. OBJECTIVES: This review addresses the effect of antiviral therapy on Bell's palsy. SEARCH STRATEGY: We updated the search of the Cochrane Neuromuscular Disease Group Trials Register (December 2008), MEDLINE (from January 1966 to December 8 2008), EMBASE (from January 1980 to December 8 2008) and LILACS (from January 1982 to December 2008). SELECTION CRITERIA: Randomized trials of antivirals with and without corticosteroids versus control therapies for the treatment of Bell's palsy. DATA COLLECTION AND ANALYSIS: Twenty-three papers were selected for consideration. MAIN RESULTS: Seven trials including 1987 participants met the inclusion criteria, adding five studies to the two in the previous review.Incomplete recovery at one year. There was no significant benefit in the rate of incomplete recovery from antivirals compared with placebo (n = 1886, RR 0.88, 95% CI 0.65 to 1.18). In meta-analyses with some unexplained heterogeneity, the outcome with antivirals was significantly worse than with corticosteroids (n = 768, RR 2.82, 95% CI 1.09 to 7.32) and the outcome with antivirals plus corticosteroids was significantly better than with placebo (n = 658, RR 0.56, 95% CI 0.41 to 0.76).Motor synkinesis or crocodile tears at one year. In single trials, there was no significant difference in long term sequelae comparing antivirals and corticosteroids with corticosteroids alone (n = 99, RR 0.39, 95% CI 0.14 to 1.07) or antivirals with corticosteroids (n = 101, RR 1.03, 95% CI 0.51 to 2.07).Adverse events.There was no significant difference in rates of adverse events between antivirals and placebo (n = 1544, RR 1.06, 95% CI 0.81 to 1.38), between antivirals and corticosteroids (n = 667, RR 0.96, 95% CI 0.65 to 1.41) or between the antiviral-corticosteroid combination and placebo (n = 658, RR 1.15, 95% CI 0.79 to 1.66). AUTHORS' CONCLUSIONS: High quality evidence showed no significant benefit from anti-herpes simplex antivirals compared with placebo in producing complete recovery from Bell's palsy. Moderate quality evidence showed that antivirals were significantly less likely than corticosteroids to produce complete recovery.</p

A haunted land

Since the nineteenth century, Australian art and writing has had a double vision of the country; as a sunny land of opportunity, and as a place of loneliness and loss. From the diminutive figures of Glover’s Aborigines in their sylvan setting to the weird bush and lonely bushmen of Clarke, McCubbin, Kendall and Lawson, the land is melancholy. Yet Leigh Astbury has shown that this settler view of the land is the product of selective vision influenced by English and American ideas of the exotic and the picaresque. It emphasised the lonely prospector or swagman rather than the miners and unionists and their powerful, if ultimately defeated, unions. The idea of sturdy independence, of “freedom on the wallaby”, appealed to town-dwellers hoping to own their own homes at least as much as to bushwomen lining their rough huts with pictures from the Ladies Home Journal. As Brian Kiernan suggests, Lawson’s early stories found their readership among people forced off the land and into the suburbs and slums of Sydney by the defeats of the 1890s. Recent fiction by white writers has, like Lawson, shown an awareness of the strangeness of the land, but it locates this strangeness more directly in the brutality and defeats of settlement. The sufferings of both settlers and of those they violently displaced continue to haunt their successors. This paper will examine the nature of this haunting in recent novels by white Australian writers

Selective versus routine use of episiotomy for vaginal birth.

Background Some clinicians believe that routine episiotomy, a surgical cut of the vagina and perineum, will prevent serious tears during childbirth. On the other hand, an episiotomy guarantees perineal trauma and sutures. Objectives To assess the effects on mother and baby of a policy of selective episiotomy ('only if needed') compared with a policy of routine episiotomy ('part of routine management') for vaginal births. Search methods We searched Cochrane Pregnancy and Childbirth's Trials Register (14 September 2016) and reference lists of retrieved studies. Selection criteria Randomised controlled trials (RCTs) comparing selective versus routine use of episiotomy, irrespective of parity, setting or surgical type of episiotomy. We included trials where either unassisted or assisted vaginal births were intended. Quasi-RCTs, trials using a cross-over design or those published in abstract form only were not eligible for inclusion in this review. Data collection and analysis Two authors independently screened studies, extracted data, and assessed risk of bias. A third author mediated where there was no clear consensus. We observed good practice for data analysis and interpretation where trialists were review authors. We used fixed-effect models unless heterogeneity precluded this, expressed results as risk ratios (RR) and 95% confidence intervals (CI), and assessed the certainty of the evidence using GRADE. Main results This updated review includes 12 studies (6177 women), 11 in women in labour for whom a vaginal birth was intended, and one in women where an assisted birth was anticipated. Two were trials each with more than 1000 women (Argentina and the UK), and the rest were smaller (from Canada, Germany, Spain, Ireland, Malaysia, Pakistan, Columbia and Saudi Arabia). Eight trials included primiparous women only, and four trials were in both primiparous and multiparous women. For risk of bias, allocation was adequately concealed and reported in nine trials; sequence generation random and adequately reported in three trials; blinding of outcomes adequate and reported in one trial, blinding of participants and personnel reported in one trial. For women where an unassisted vaginal birth was anticipated, a policy of selective episiotomy may result in 30% fewer women experiencing severe perineal/vaginal trauma (RR 0.70, 95% CI 0.52 to 0.94; 5375 women; eight RCTs; low-certainty evidence). We do not know if there is a difference for blood loss at delivery (an average of 27 mL less with selective episiotomy, 95% CI from 75 mL less to 20 mL more; two trials, 336 women, very low-certainty evidence). Both selective and routine episiotomy have little or no effect on infants with Apgar score less than seven at five minutes (four trials, no events; 3908 women, moderate-certainty evidence); and there may be little or no difference in perineal infection (RR 0.90, 95% CI 0.45 to 1.82, three trials, 1467 participants, low-certainty evidence). For pain, we do not know if selective episiotomy compared with routine results in fewer women with moderate or severe perineal pain (measured on a visual analogue scale) at three days postpartum (RR 0.71, 95% CI 0.48 to 1.05, one trial, 165 participants, very low-certainty evidence). There is probably little or no difference for long-term (six months or more) dyspareunia (RR1.14, 95% CI 0.84 to 1.53, three trials, 1107 participants, moderate-certainty evidence); and there may be little or no difference for long-term (six months or more) urinary incontinence (average RR 0.98, 95% CI 0.67 to 1.44, three trials, 1107 participants, low-certainty evidence). One trial reported genital prolapse at three years postpartum. There was no clear difference between the two groups (RR 0.30, 95% CI 0.06 to 1.41; 365 women; one trial, low certainty evidence). Other outcomes relating to long-term effects were not reported (urinary fistula, rectal fistula, and faecal incontinence). Subgroup analyses by parity (primiparae versus multiparae) and by surgical method (midline versus mediolateral episiotomy) did not identify any modifying effects. Pain was not well assessed, and women's preferences were not reported. One trial examined selective episiotomy compared with routine episiotomy in women where an operative vaginal delivery was intended in 175 women, and did not show clear difference on severe perineal trauma between the restrictive and routine use of episiotomy, but the analysis was underpowered

Automatic Detection of Online Jihadist Hate Speech

We have developed a system that automatically detects online jihadist hate speech with over 80% accuracy, by using techniques from Natural Language Processing and Machine Learning. The system is trained on a corpus of 45,000 subversive Twitter messages collected from October 2014 to December 2016. We present a qualitative and quantitative analysis of the jihadist rhetoric in the corpus, examine the network of Twitter users, outline the technical procedure used to train the system, and discuss examples of use.Comment: 31 page

Medical students writing on death, dying and palliative care : a qualitative analysis of reflective essays

Background: Medical students and doctors are becoming better prepared to care for patients with palliative care needs and support patients at the end of life. This preparation needs to start at medical school. Objective: To assess how medical students learn about death, dying and palliative care during a clinical placement using reflective essays and to provide insights to improve medical education about end of life care and/or palliative care. Methods: Qualitative study in which all reflective essays written by third year medical students in one year from a UK medical school were searched electronically for those that included ‘death’, ‘dying’ and ‘palliative care’. The anonymised data were managed using QSR NVivo 10 software, and a systematic analysis was conducted in three distinct phases: (1) open coding; (2) axial coding and (3) selective coding. Ethical approval was received. Results: Fifty-four essays met the inclusion criteria from 241 essays screened for the terms ‘death’, ‘dying’ or ‘palliative’, 22 students gave consent for participation and their 24 essays were included. Saturation of themes was reached. Three overarching themes were identified: emotions, empathy, and experiential and reflective learning. Students emphasised trying to develop a balance between showing empathy and their emotional state. Students learned a lot from clinical encounters and watching doctors manage difficult situations, as well as from their refection during and after the experience. Conclusions: Reflective essays give insights into the way students learn about death, dying and palliative care and how it affects them personally as well as the preparation that is needed to be better equipped to deal with these kinds of experiences. Analysis of the essays enabled the proposal of new strategies to help make them more effective learning tools and to optimise students’ learning from a palliative care attachment

Does Platelet-Rich Plasma Therapy in Arthroscopic Rotator Cuff Repair Improve Patient Outcome?

OBJECTIVE: The objective of this selective EBM review is to determine whether or not platelet rich plasma therapy (PRP) improves patient outcome in arthroscopic rotator cuff repair. STUDY DESIGN: Review of three primary research studies published in the English language in 2011. DATA SOURCES: Three double blind, randomized, controlled trials analyzing the effect of augmentation of rotator cuff repair surgery with PRP therapy were found using PubMed. OUTCOMES MEASURED: Each of the three studies measured the effectiveness of PRP therapy in arthroscopic rotator cuff repair, with specific regards to pain improvement after surgery, healing time and durability of the repair. Each patient was measured using the Constant score preoperatively and at varying intervals postoperatively from three months up to two years. The Constant score measures pain, limitations of activities of daily living, range of motion andstrength. RESULTS: Three randomized controlled trials were included in this review. The study by Randelli found that there was a significant increase in Constant scores for the PRP group at 3 months postoperative, but no significant difference was found at 6, 12 and 24 months postoperative. The study by Sánchez Márquez found no significant difference between the Constant Scores of both groups at 12 months. The study by Castricini found that there was no significant difference inConstant score at an average of 20.2 months postoperative. CONCLUSIONS: Based upon analysis of three RCT’s, one study found significant improvement in pain and strength at various postoperative intervals, while two additional studies found no significant improvement. The mixed nature of these results identifies the need for further investigation into the effectiveness of this treatment method
