RESUMO
BACKGROUND: Prominent lower front teeth may be associated with a large or prognathic lower jaw (mandible) or a small or retrusive upper jaw (maxilla). Edward Angle, who may be considered the father of modern orthodontics, classified the malocclusion in this situation as Class III. The individual is described as having a negative or reverse overjet as the lower front teeth are more prominent than the upper front teeth. OBJECTIVES: The purpose of this systematic review was to evaluate different treatments of Angle Class III malocclusion in adults. SEARCH METHODS: The following databases were searched: Cochrane Oral Health Group Trials Register (to 22 March 2012); CENTRAL (The Cochrane Library 2012, Issue 1); MEDLINE via OVID (1950 to 22 March 2012); EMBASE via OVID (1980 to 22 March 2012); LILACs (1982 to 22 March 2012); BBO (1986 to 22 March 2012); and SciELO (1997 to 22 March 2012). SELECTION CRITERIA: All randomized or quasi-randomized controlled trials of treatments for adults with an Angle Class III malocclusion were included. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed the eligibility of the identified reports. Two review authors independently extracted data and assessed the risk of bias in the included studies. The mean differences with 95% confidence intervals were calculated for continuous data. MAIN RESULTS: Two randomized controlled trials were included in this review. There are different types of surgery for this type of malocclusion but only trials of mandible reduction surgery were identified. One trial compared intraoral vertical ramus osteotomy (IVRO) with sagittal split ramus osteotomy (SSRO) and the other trial compared vertical ramus osteotomy (VRO) with and without osteosynthesis. Neither trial found any difference between the two treatments. The trials did not provide adequate data for assessing effectiveness of the techniques described. AUTHORS' CONCLUSIONS: There is insufficient evidence from the two included trials, to conclude that one procedure is better or worse than another. The included trials compared different interventions and were at high risk of bias and therefore no implications for practice can be given. Further high quality randomized controlled trials with long term follow-up are required.

BACKGROUND: Restless legs syndrome (RLS) is a common disease affecting about 5% to 15% of the population. Symptoms of RLS can be severe in a minority of and can have a major impact on sleep, mostly sleep initiation, and quality of life. Benzodiazepines are drugs that can induce and maintain sleep and, hence, intuitively are thought to be beneficial to people with RLS. Altough benzodiazepines, particularly clonazepam, are used to treat RLS symptoms, a systematic review done by the American Academy of Sleep Medicine stated that benzodiazepines should not be used as a first-line treatment, although could be used as a coadjuvant therapy. OBJECTIVES: To evaluate the efficacy and safety of benzodiazepine compared to placebo or other treatment for idiopathic RLS, including unconfounded trials comparing benzodiazepines versus open control. SEARCH METHODS: In March 2016 we searched CENTRAL, MEDLINE, Embase and LILACS We checked the references of each study and contacted study authors to identify any additional studies. We considered studies published in any language. SELECTION CRITERIA: Randomised clinical trials of benzodiazepine treatment in idiopathic RLS. DATA COLLECTION AND ANALYSIS: We did not perform data collection and analysis, since we did not include any studies, MAIN RESULTS: We did not identify any studies that met the inclusion criteria of the review. Two cross-over studies are awaiting classification because the cross-over trials did not give data at the end of the first cross-over period. AUTHORS' CONCLUSIONS: The effectiveness of benzodiazepines for RLS treatment is currently unknown.

Spinocerebellar ataxia type 6 (SCA6) is usually described as a pure ataxia syndrome. However, SCA6 patients may have sleep complaints. In this paper, sleep disorders were investigated in patients with SCA6. Twelve SCA6 patients and 12 subjects matched by gender, age and body mass index (control group) underwent polysomnography and clinical investigation for sleep disorders. SCA6 had a higher frequency of snoring (P = 0.01), a higher index of awakening due to respiratory events (P = 0.003) and central apnea events during sleep (P = 0.024), a longer sleep Stage N1 (P = 0.02) and a lower sleep Stage N3 (P = 0.05) in SCA6 patients than in control subjects. SCA6 patients had a reduction in slow wave sleep and a higher frequency of snoring and respiratory disorders during sleep when compared to the control group.

BACKGROUND: This is an updated version of the original Cochrane review, published in 2009, Issue 2.Kleine-Levin syndrome (KLS) is a rare disorder that mainly affects adolescent men. It is characterised by recurrent episodes of hypersomnia, usually accompanied by hyperphagia, cognitive and mood disturbances, abnormal behaviour, such as hypersexuality, and signs of dysautonomia.In 1990, the diagnostic criteria for Kleine-Levin syndrome were modified in the International Classification of Sleep Disorders, where KLS was defined as a syndrome comprised of recurring episodes of undue sleepiness lasting some days, which may or may not be associated with hyperphagia and abnormal behaviour. According to the International Classification of Sleepiness Disorders, 3rd version (ICSD-3), revised in 2014, the Kleine-Levin syndrome is a disorder characterized by recurrent episodes of hypersomnia that last from two days to four weeks, with at least annual recurrence, and hyperphagia (rapid consumption of a large amount of food), usually with onset in early adolescence in males but occasionally in later life and in women. A monosymptomatic form of the disorder with hypersomnia only can occur without binge eating or hypersexuality.The cause of Kleine-Levin syndrome remains unknown, and several treatment strategies have been used. Some medications have been reported to provide benefit in the treatment of patients with KLS, but because of the rarity of the condition, no long-term follow-up therapies have yet been described. OBJECTIVES: This review aimed to evaluate:1. whether pharmacological treatment for Kleine Levin syndrome was effective and safe.2. which drug or category of drugs was effective and safe. SEARCH METHODS: For the latest update, we searched the following sources: the Cochrane Epilepsy Group Specialized Register (7 April 2016); the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online CRSO (7 April 2016); MEDLINE (1946 to April 2016); LILACS (7 April 2016); ClinicalTrials.gov (7 April 2016); WHO International Clinical Trials Registry Platform ICTRP (7 April 2016); reference lists of sleep medicine textbooks; review articles and reference lists of articles identified by the search strategies. SELECTION CRITERIA: All randomised controlled trials (RCTs) and quasi-randomised controlled trials looking at pharmacological interventions for Kleine-Levin syndrome were eligible. We had planned to include both parallel-group and cross-over studies. DATA COLLECTION AND ANALYSIS: Two review authors (MMO and CC) had planned to extract the data reported in the original articles. MAIN RESULTS: No studies met the inclusion criteria for this systematic review. AUTHORS' CONCLUSIONS: Therapeutic trials of pharmacological treatment for Kleine-Levin syndrome with a double-blind, placebo-controlled design are needed.

BACKGROUND: Apnoea is a breathing disorder marked by the absence of airflow at the nose or mouth. In children, risk factors include adenotonsillar hypertrophy, obesity, neuromuscular disorders and craniofacial anomalies. The most common treatment for obstructive sleep apnoea syndrome (OSAS) in childhood is adeno-tonsillectomy. This approach is limited by its surgical risks, mostly in children with comorbidities and, in some patients, by recurrence that can be associated with craniofacial problems. Oral appliances and functional orthopaedic appliances have been used for patients who have OSAS and craniofacial anomalies because they hold the lower jaw (mandible) forwards which potentially enlarges the upper airway and increases the upper airspace, improving the respiratory function. OBJECTIVES: To assess the effects of oral appliances or functional orthopaedic appliances for obstructive sleep apnoea in children. SEARCH METHODS: We searched the following electronic databases: Cochrane Oral Health's Trials Register (to 7 April 2016); Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 3) in the Cochrane Library (searched 7 April 2016); MEDLINE Ovid (1946 to 7 April 2016); Embase Ovid (1980 to 7 April 2016); LILACS BIREME (from 1982 to 7 April 2016); BBO BIREME (from 1986 to 7 April 2016) and SciELO Web of Science (from 1997 to 7 April 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials on 7 April 2016. We placed no restrictions on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: All randomised or quasi-randomised controlled trials comparing all types of oral and functional orthopaedic appliances with placebo or no treatment, in children 15 years old or younger. PRIMARY OUTCOME: reduction of apnoea to less than one episode per hour. SECONDARY OUTCOMES: dental and skeletal relationship, sleep parameters improvement, cognitive and phonoaudiological function, behavioural problems, quality of life, side effects (tolerability) and economic evaluation. DATA COLLECTION AND ANALYSIS: Two review authors screened studies and extracted data independently. Authors were contacted for additional information. We calculated risk ratios with 95% confidence intervals for all important dichotomous outcomes. We assessed the quality of the evidence of included studies using GRADEpro software. MAIN RESULTS: The initial search identified 686 trials. Only one trial, reporting the results from a total of 23 children and comparing an oral appliance to no treatment, was suitable for inclusion in the review. The trial assessed apnoea-hypopnoea, daytime symptoms (sleepiness, irritability, tiredness, school problems, morning headache, thirstiness in the morning, oral breathing and nasal stuffiness) and night-time symptoms (habitual snoring, restless sleep and nightmares measured by questionnaire). Results were inconsistent across outcomes measures and time points. The evidence was considered very low quality. AUTHORS' CONCLUSIONS: There is insufficient evidence to support or refute the effectiveness of oral appliances and functional orthopaedic appliances for the treatment of obstructive sleep apnoea in children. Oral appliances or functional orthopaedic appliances may be considered in specified cases as an auxiliary in the treatment of children who have craniofacial anomalies which are risk factors for apnoea.

BACKGROUND: Restless legs syndrome (RLS) is a distressing and common neurological disorder that may have a huge impact in the quality of life of those with frequent and intense symptoms. Patients complain of unpleasant sensations in the legs, at or before bedtime, and feel an urge to move the legs, which improves with movement, such as walking. Symptoms start with the patient at rest (e.g. sitting or lying down), and follow a circadian pattern, increasing during the evening or at night. Many pharmacological intervention are available for RLS, including drugs used to treat Parkinson's disease (L-Dopa and dopaminergic agonists), epilepsy (anticonvulsants), anxiety (benzodiazepines), and pain (opioids). Dopaminergic drugs are those most frequently used for treatment of RLS, but some patients do not respond effectively and require other medication. Opioids, a class of medications used to treat severe pain, seem to be effective in treating RLS symptoms, and are recommended for patients with severe symptoms, because RLS and pain appear to share the same mechanism in the central nervous system. All available drugs are associated to some degree with side effects, which can impede treatment. Opioids are associated with adverse events such as constipation, tolerance, and dependence. This justifies the conduct of a systematic review to ascertain whether opioids are safe and effective for treatment of RLS. OBJECTIVES: To asses the effects of opioids compared to placebo treatment for restless legs syndrome in adults. SEARCH METHODS: We searched the Cochrane Central Register of Controlled trials, CENTRAL 2016, issue 4 and MEDLINE, EMBASE, and LILACS up to April 2016, using a search strategy adapted by Cochraneto identify randomised clinical trials. We checked the references of each study and established personal communication with other authors to identify any additional studies. We considered publications in all languages. SELECTION CRITERIA: Randomised controlled clinical trials of opioid treatment in adults with idiopathic RLS. DATA COLLECTION AND ANALYSIS: Two review authors independently screened articles, independently extracted data into a standard form, and assessed for risk of bias. If necessary, they discussed discrepancies with a third researcher to resolve any doubts. MAIN RESULTS: We included one randomised clinical trial (N = 304 randomised; 204 completed; 276 analysed) that evaluated opioids (prolonged release oxycodone/naloxone) versus placebo. After 12 weeks, RSL symptoms had improved more in the drug group than in the placebo group (using the IRLSSS: MD -7.0; 95% CI -9.69 to -4.31 and the CGI: MD -1.11; 95% CI -1.49 to -0.73). More patients in the drug group than in the placebo group were drug responders (using the IRLSSS: RR 1.82; 95% CI 1.37 to 2.42 and the CGI: RR1.92; 95% ICI 1.49 to 2.48). The proportion of remitters was greater in the drug group than in the placebo group (using the IRLSSS: RR 2.14; 95% CI 1.45 to 3.16). Quality of life scores also improved more in the drug group than in the placebo group (MD -0.73; 95% CI -1.1 to -0.36). Quality of sleep was improved more in the drug group measured by sleep adequacy (MD -0.74; 95% CI -1.15 to -0.33), and sleep quantity (MD 0.89; 95% CI 0.52 to 1.26).There was no difference between groups for daytime somnolence, trouble staying awake during the day, or naps during the day. More adverse events were reported in the drug group (RR 1.22; 95% CI 1.07 to 1.39). The major adverse events were gastrointestinal problems, fatigue, and headache. AUTHORS' CONCLUSIONS: Opioids seem to be effective for treating RLS symptoms, but there are no definitive data regarding the important problem of safety. This conclusion is based on only one study with a high dropout rate (moderate quality evidence).

BACKGROUND: Sleep bruxism is an oral activity characterized by involuntary teeth grinding or clenching during sleep. Several forms of treatment have been proposed for this disorder, including behavioural, dental and pharmacological strategies. OBJECTIVES: To evaluate the effectiveness and safety of pharmacological therapy for the treatment of sleep bruxism compared with other drugs, no treatment or placebo. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 8, 2014), MEDLINE (1966 to August 2014), EMBASE (1980 to August 2013) and LILACS (1982 to August 2014). We identified additional reports from the reference lists of retrieved reports and from reviews on treatment of sleep bruxism. We applied no language restrictions. SELECTION CRITERIA: We selected randomized controlled trials (RCTs) or quasi-RCTs that compared drugs with other drugs, no treatment or placebo in people with sleep bruxism. DATA COLLECTION AND ANALYSIS: Review authors carried out data extraction and quality assessment of the included trials independently and in duplicate. We discussed discrepancies until we reached consensus. We consulted a third review author in cases of persistent disagreement. We contacted authors of primary studies when necessary. MAIN RESULTS: We identified 18 potentially relevant RCTs, but only seven met the inclusion criteria. All studies had a small number of participants, ranging from seven to 16 people per study and had a cross-over design. Three studies were of low risk of bias, while four were of uncertain risk. Amitriptyline (three studies), bromocriptine (one study), clonidine (one study), propranolol (one study), levodopa (Prolopa®) (one study) and tryptophan (one study) were compared with placebo. Studies evaluating bromocriptine, clonidine, propranolol and levodopa reported our primary outcome of indices of bruxism motor activity.Results were imprecise and consistent with benefit, no difference or harm. These were the specific findings for each of the drugs according to specific outcomes: 1. Amitriptyline versus placebo for masseteric electromyography (EMG) activity per minute: standardized mean difference (SMD) -0.28 (95% confidence interval (CI) -0.91 to 0.34; P value = 0.37), 2. bromocriptine versus placebo for bruxism episodes per hour: mean difference (MD) 0.60 (95% CI -2.93 to 4.13), bruxism bursts per hour: MD -2.00 (95% CI -53.47 to 49.47), bruxism bursts per episode: MD 0.50 (95% CI -1.85 to 2.85) or number of episodes with grinding noise: MD 2.40 (95% CI -24.00 to 28.80), 3. clonidine versus placebo for number of bruxism episodes per hour: MD -2.41 (95% CI -4.84 to 0.02), 4. propranolol versus placebo for the number of bruxism episodes per hour: MD 1.16 (95% CI -1.89 to 4.21), 5. L-tryptophan versus placebo for masseteric EMG activity per second: SMD 0.08 (95% CI -0.90 to 1.06) and 6. levodopa versus placebo for bruxism episodes per hour of sleep: MD -1.47 (95% CI -3.64 to 0.70), for bruxism bursts per episode: MD 0.06 (95% CI -2.47 to 2.59).We combined several secondary outcomes (sleep duration, masseteric EMG activity per minute and pain intensity) in a meta-analysis for comparison of amitriptyline with placebo. The results for most comparisons were uncertain because of statistical imprecision. One study reported that clonidine reduced rapid eye movement (REM) sleep stage and increased the second stage of sleep. However, results for other sleep-related outcomes with clonidine were uncertain. Adverse effects were frequent in people who took amitriptyline (5/10 had drowsiness, difficulty awakening in the morning, insomnia or xerostomia compared with 0/10 in the placebo group), as well as in people who received propranolol (7/16 had moderate-to-severe xerostomia compare with 2/16 in the placebo group). Clonidine was associated with prolonged morning hypotension in three of 16 participants. The use of preventive medication avoided any adverse effects in people treated with levodopa and bromocriptine. AUTHORS' CONCLUSIONS: There was insufficient evidence on the effectiveness of pharmacotherapy for the treatment of sleep bruxism. This systematic review points to the need for more, well-designed, RCTs with larger sample sizes and adequate methods of allocation, outcome assessment and duration of follow-up. Ideally, parallel RCTs should be used in future studies to avoid the bias associated with cross-over studies. There is a need to standardize the outcomes of RCTs on treatments for sleep bruxism.

BACKGROUND: Anterior open bite occurs when there is a lack of vertical overlap of the upper and lower incisors. The aetiology is multifactorial including: oral habits, unfavourable growth patterns, enlarged lymphatic tissue with mouth breathing. Several treatments have been proposed to correct this malocclusion, but interventions are not supported by strong scientific evidence. OBJECTIVES: The aim of this systematic review was to evaluate orthodontic and orthopaedic treatments to correct anterior open bite in children. SEARCH METHODS: The following databases were searched: the Cochrane Oral Health Group's Trials Register (to 14 February 2014); the Cochrane Central Register of Controlled Trials (CENTRAL)(The Cochrane Library 2014, Issue 1); MEDLINE via OVID (1946 to 14 February 2014); EMBASE via OVID (1980 to 14 February 2014); LILACS via BIREME Virtual Health Library (1982 to 14 February 2014); BBO via BIREME Virtual Health Library (1980 to 14 February 2014); and SciELO (1997 to 14 February 2014). We searched for ongoing trials via ClinicalTrials.gov (to 14 February 2014). Chinese journals were handsearched and the bibliographies of papers were retrieved. SELECTION CRITERIA: All randomised or quasi-randomised controlled trials of orthodontic or orthopaedic treatments or both to correct anterior open bite in children. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the eligibility of all reports identified. Risk ratios (RRs) and corresponding 95% confidence intervals (CIs) were calculated for dichotomous data. The continuous data were expressed as described by the author. MAIN RESULTS: Three randomised controlled trials were included comparing: effects of Frankel's function regulator-4 (FR-4) with lip-seal training versus no treatment; repelling-magnet splints versus bite-blocks; and palatal crib associated with high-pull chincup versus no treatment.The study comparing repelling-magnet splints versus bite-blocks could not be analysed because the authors interrupted the treatment earlier than planned due to side effects in four of ten patients.FR-4 associated with lip-seal training (RR = 0.02 (95% CI 0.00 to 0.38)) and removable palatal crib associated with high-pull chincup (RR = 0.23 (95% CI 0.11 to 0.48)) were able to correct anterior open bite.No study described: randomisation process, sample size calculation, there was not blinding in the cephalometric analysis and the two studies evaluated two interventions at the same time. These results should be therefore viewed with caution. AUTHORS' CONCLUSIONS: There is weak evidence that the interventions FR-4 with lip-seal training and palatal crib associated with high-pull chincup are able to correct anterior open bite. Given that the trials included have potential bias, these results must be viewed with caution. Recommendations for clinical practice cannot be made based only on the results of these trials. More randomised controlled trials are needed to elucidate the interventions for treating anterior open bite.

BACKGROUND: This is an updated version of the original Cochrane review, published in Issue 2, 2009.Kleine-Levin syndrome (KLS) is a rare disorder that mainly affects adolescent men. It is characterised by recurrent episodes of hypersomnia, usually accompanied by hyperphagia, cognitive and mood disturbances, abnormal behavior such as hypersexuality and signs of dysautonomia.In 1990 the diagnostic criteria for Kleine-Levin syndrome were modified in the International Classification of Sleep Disorders, where KLS was defined as a syndrome composed of recurring episodes of undue sleepiness lasting some days, which may or may not be associated with hyperphagia and abnormal behavior.The cause of Kleine-Levin syndrome remains unknown, and several treatment strategies have been used. Some medications have been reported to provide benefit in the treatment of patients with KLS, but because of the rarity of the condition, no long-term follow-up therapies have yet been described. OBJECTIVES: This review aimed to evaluate:1. whether pharmacological treatment for Kleine Levin syndrome is effective and safe.2. which drug or category of drugs is effective and safe. SEARCH METHODS: We obtained relevant trials from the following sources: the Cochrane Epilepsy Group Specialized Register (2 May 2013); the Cochrane Central Register of Controlled Trials (CENTRAL Issue 4, The Cochrane Library, April 2013); MEDLINE (1946 to 2 May 2013); SCOPUS (2 May 2013); LILACS (2 May 2013); ClinicalTrials.gov (2 May 2013); WHO International Clinical Trials Registry Platform ICTRP (2 May 2013); reference lists of sleep medicine textbooks; review articles and reference lists of articles identified by the search strategies. SELECTION CRITERIA: All randomised controlled trials (RCTs) and quasi-randomised controlled trials looking at pharmacological interventions for Kleine-Levin syndrome were selected. We included both parallel-group and cross-over studies. DATA COLLECTION AND ANALYSIS: Two review authors (MMO and CC) extracted the data reported in the original articles. MAIN RESULTS: No studies met the inclusion criteria for this systematic review. AUTHORS' CONCLUSIONS: Therapeutic trials of pharmacological treatment for Kleine-Levin syndrome with a double-blind, placebo-controlled design are needed.

BACKGROUND: Prominent lower front teeth may be associated with a large or prognathic lower jaw (mandible) or a small or retrusive upper jaw (maxilla). Edward Angle, who may be considered the father of modern orthodontics, classified the malocclusion in this situation as Class III. The individual is described as having a negative or reverse overjet as the lower front teeth are more prominent than the upper front teeth. OBJECTIVES: The purpose of this systematic review was to evaluate different treatments of Angle Class III malocclusion in adults. SEARCH METHODS: The following databases were searched: Cochrane Oral Health Group Trials Register (to 22 March 2012); CENTRAL (The Cochrane Library 2012, Issue 1); MEDLINE via OVID (1950 to 22 March 2012); EMBASE via OVID (1980 to 22 March 2012); LILACs (1982 to 22 March 2012); BBO (1986 to 22 March 2012); and SciELO (1997 to 22 March 2012). SELECTION CRITERIA: All randomized or quasi-randomized controlled trials of treatments for adults with an Angle Class III malocclusion were included. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed the eligibility of the identified reports. Two review authors independently extracted data and assessed the risk of bias in the included studies. The mean differences with 95% confidence intervals were calculated for continuous data. MAIN RESULTS: Two randomized controlled trials were included in this review. There are different types of surgery for this type of malocclusion but only trials of mandible reduction surgery were identified. One trial compared intraoral vertical ramus osteotomy (IVRO) with sagittal split ramus osteotomy (SSRO) and the other trial compared vertical ramus osteotomy (VRO) with and without osteosynthesis. Neither trial found any difference between the two treatments. The trials did not provide adequate data for assessing effectiveness of the techniques described. AUTHORS' CONCLUSIONS: There is insufficient evidence from the two included trials, to conclude that one procedure is better or worse than another. The included trials compared different interventions and were at high risk of bias and therefore no implications for practice can be given. Further high quality randomized controlled trials with long term follow-up are required.

BACKGROUND: The brain is at risk of ischaemia during a variety of neurosurgical procedures, and this can lead to devastating results. Induced hypothermia is the controlled lowering of core body temperature for therapeutic purposes. This remains the current practice during neurosurgery for the prevention or minimization of ischaemic brain injury. Brain surgery may lead to severe complications due to factors such as requirement for brain retraction, vessel occlusion, and intraoperative haemorrhage. Many anaesthesiologists believe that induced hypothermia is indicated to protect the central nervous system during surgery. Although hypothermia is often used during brain surgery, clinical efficacy has not yet been established. OBJECTIVES: To evaluate the effectiveness and safety of induced hypothermia versus normothermia for neuroprotection in patients undergoing brain surgery. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 10), MEDLINE, LILACS, EMBASE and Current Controlled Trials (from inception to November 2010), reference lists of identified trials, and bibliographies of published reviews. We also contacted researchers in the field. There were no language restrictions. SELECTION CRITERIA: We included randomized controlled trials and quasi-randomized controlled trials of induced hypothermia versus normothermia for neuroprotection in patients undergoing brain surgery. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information. MAIN RESULTS: We included four trials of cooling for cerebral protection during brain surgery, involving a total of 1219 patients. We did not find any evidence that hypothermia for neuroprotection in patients undergoing brain surgery is either effective or unsafe when compared to normothermia. AUTHORS' CONCLUSIONS: Although there is some evidence that mild hypothermia is safe, its effectiveness is not clear when compared with normothermia. We need to perform more clinical trials in order to establish the benefit, if any, of hypothermia for cerebral protection during brain surgery before making firm recommendations for the routine use of this intervention.

BACKGROUND: Bell's palsy (idiopathic facial paralysis) is commonly treated by various physical therapy strategies and devices, but there are many questions about their efficacy. OBJECTIVES: To evaluate physical therapies for Bell's palsy (idiopathic facial palsy). SEARCH METHODS: We searched the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2011), MEDLINE (January 1966 to February 2011), EMBASE (January 1946 to February 2011), LILACS (January 1982 to February 2011), PEDro (from 1929 to February 2011), and CINAHL (January 1982 to February 2011). We included searches in clinical trials register databases until February 2011. SELECTION CRITERIA: We selected randomised or quasi-randomised controlled trials involving any physical therapy. We included participants of any age with a diagnosis of Bell's palsy and all degrees of severity. The outcome measures were: incomplete recovery six months after randomisation, motor synkinesis, crocodile tears or facial spasm six months after onset, incomplete recovery after one year and adverse effects attributable to the intervention. DATA COLLECTION AND ANALYSIS: Two authors independently scrutinised titles and abstracts identified from the search results. Two authors independently carried out risk of bias assessments, which , took into account secure methods of randomisation, allocation concealment, observer blinding, patient blinding, incomplete outcome data, selective outcome reporting and other bias. Two authors independently extracted data using a specially constructed data extraction form. We undertook separate subgroup analyses of participants with more and less severe disability. MAIN RESULTS: For this update to the original review, the search identified 65 potentially relevant articles. Twelve studies met the inclusion criteria (872 participants). Four trials studied the efficacy of electrical stimulation (313 participants), three trials studied exercises (199 participants), and five studies compared or combined some form of physical therapy with acupuncture (360 participants). For most outcomes we were unable to perform meta-analysis because the interventions and outcomes were not comparable.For the primary outcome of incomplete recovery after six months, electrostimulation produced no benefit over placebo (moderate quality evidence from one study with 86 participants). Low quality comparisons of electrostimulation with prednisolone (an active treatment)(149 participants), or the addition of electrostimulation to hot packs, massage and facial exercises (22 participants), reported no significant differences. Similarly a meta-analysis from two studies, one of three months and the other of six months duration, (142 participants) found no statistically significant difference in synkinesis, a complication of Bell's palsy, between participants receiving electrostimulation and controls. A single low quality study (56 participants), which reported at three months, found worse functional recovery with electrostimulation (mean difference (MD) 12.00 points (scale of 0 to 100) 95% confidence interval (CI) 1.26 to 22.74).Two trials of facial exercises, both at high risk of bias, found no difference in incomplete recovery at six months when exercises were compared to waiting list controls or conventional therapy. There is evidence from a single small study (34 participants) of moderate quality that exercises are beneficial on measures of facial disability to people with chronic facial palsy when compared with controls (MD 20.40 points (scale of 0 to 100), 95% CI 8.76 to 32.04) and from another single low quality study with 145 people with acute cases treated for three months where significantly fewer participants developed facial motor synkinesis after exercise (risk ratio 0.24, 95% CI 0.08 to 0.69). The same study showed statistically significant reduction in time for complete recovery, mainly in more severe cases (47 participants, MD -2.10 weeks, 95% CI -3.15 to -1.05) but this was not a prespecified outcome in this meta analysis.Acupuncture studies did not provide useful data as all were short and at high risk of bias. None of the studies included adverse events as an outcome. AUTHORS' CONCLUSIONS: There is no high quality evidence to support significant benefit or harm from any physical therapy for idiopathic facial paralysis. There is low quality evidence that tailored facial exercises can help to improve facial function, mainly for people with moderate paralysis and chronic cases. There is low quality evidence that facial exercise reduces sequelae in acute cases. The suggested effects of tailored facial exercises need to be confirmed with good quality randomised controlled trials.

INTRODUCTION: The Sleep Disturbance Scale for Children (SDSC) is a 26-item instrument for evaluating sleep among children aged 3-18 years. It differentiates among conditions such as disorders of initiating and maintaining sleep, sleep breathing disorders, disorders of arousal, sleep-wake transition disorders, excessive somnolence, and sleep hyperhydrosis. The aim of this study was to translate, culturally adapt, and validate it for Brazilian Portuguese. METHOD: The study was carried out in two phases: (1) forward translation, back translation, pretesting, and calculation of sample size; (2) validation: reliability (Chronbach's alpha), convergent analysis (Pearson correlation), and discriminatory validity (comparing the scores of the test with the results of polysomnography). One hundred children, aged 3-18 years, accompanied by their parents and/or guardians participated in the phases. PSG studies have been done to calculate the sample size and validation. RESULTS: The scale instructions and items were adapted regarding semantic, experiential, conceptual, and cultural equivalence validation. The scale structure related to visual communication was also adapted to Brazilian population preference and habits, and this resulted in a chart with clear instructions and easy recognition of the statements and possible responses. Reliability analysis showed values greater than 0.55. There has been reasonable convergent validity. Discriminatory validity using the PSG study for positive sleep-disordered breathing (SDB) was 8.9, attesting discriminatory validity only for SDB. The three questions of the scale can screen SDB. CONCLUSION: The SDSC was translated, adapted and validated for Brazilian Portuguese, and it presented internal consistency and convergent and discriminatory validity. It can be used in population-based studies in order to screen for sleep-disordered breathing in children.

BACKGROUND: Bell's palsy (idiopathic facial paralysis) is commonly treated by physical therapy services with various therapeutic strategies and devices. There are many questions about their efficacy and effectiveness. OBJECTIVES: To evaluate the efficacy of physical therapies on the outcome of Bell's palsy. SEARCH STRATEGY: We searched the Cochrane Neuromuscular Disease Group Trials Register (February 2008), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2007), MEDLINE (January 1966 to February 2008), EMBASE (January 1980 to February 2008), LILACS (January 1982 to February 2008), PEDro (from 1929 to February 2008), and CINAHL (January 1982 to February 2008). SELECTION CRITERIA: We selected randomised or quasi-randomised controlled trials involving any physical therapy. We included participants of any age with a diagnosis of Bell's palsy and all degrees of severity. The outcome measures were: incomplete recovery six months after randomisation, motor synkinesis, crocodile tears or facial spasm six months after onset, incomplete recovery after one year and adverse effects attributable to the intervention. DATA COLLECTION AND ANALYSIS: Titles and abstracts identified from the register were scrutinized. The assessment of methodological quality took into account secure method of randomisation, allocation concealment, observer blinding, patient blinding, differences at baseline of the experimental groups, and completeness of follow-up. Data were extracted using a specially constructed data extraction form. Separate subgroup analyses of participants with more and less severe disability were undertaken. MAIN RESULTS: The search identified 45 potentially relevant articles. Six studies met the inclusion criteria. Three trials studied the efficacy of electrostimulation (294 participants) and three exercises (253 participants). Neither treatment produced significantly more improvement than the control treatment or no treatment. There was limited evidence that improvement began earlier in the exercise group. AUTHORS' CONCLUSIONS: There is no evidence of significant benefit or harm from any physical therapy for idiopathic facial paralysis. The possibility that facial exercise reduces time to recover and sequelae needs confirming with good quality randomised controlled trials.

OBJECTIVE: Few studies have quantified the prevalence of restless legs syndrome (RLS) in patients with post-polio syndrome (PPS). Our objective was to assess the prevalence and severity of RLS in patients with PPS and to examine the demographic characteristics of this population. METHOD: This was a cross-sectional study conducted from April 2010 to May 2012 at the outpatient Neuromuscular Disorders clinic of Universidade Federal de São Paulo, São Paulo, Brazil. We evaluated 119 patients with PPS, consecutively recruited, and investigated for RLS based on the diagnostic criteria established by the International Restless Legs Syndrome Study Group (IRLSSG). Patients were evaluated with the Brazilian version of the IRLSSG severity scale. RESULTS: The prevalence of RLS was 36% (n = 43; 32 women and 11 men). The ages at onset of RLS (median = 41 years) and PPS (median = 41 years) were concurrent, and the correlation between onset of symptoms of RLS and onset of symptoms of PPS was positive and very strong (Spearman r = 0.93, p = 0.01). The median RLS severity was 23 (range, 20-28). Low educational achievement and depression were predictive of RLS development. CONCLUSION: In the largest population of patients with PPS studied to date, our results indicate a high prevalence of RLS, marked disease severity, and concomitant onset of both conditions in many patients with PPS. Further studies are needed to elucidate a possible pathophysiologic mechanism linking these two conditions. We suggest that all post-polio patients with sensory and motor complaints in the legs be investigated for RLS.

CONTEXT: Hemiparesia changes quality of life of patients with stroke making difficult a normal life. OBJECTIVE: To evaluate the effect of Functional Eletric Orthesis (FEO) applied over the paretic leg in the quality of life of stroke patients. METHOD: The quality of life of 50 stroke patients of Associacao de Assistencia a Crianca Deficiente (AACD) was evaluated with SF-36 questionnaire before and after the treatment with a FEO for rehabilitation of walking. We analyzed data according to gender and affected hemisphere. RESULTS: The average values from all domains of SF-36 improved significantly (p<0.001). Female patients improved more than male in Emotional Domain (p=0.04) and presented a trend to be better regarding Bodily Pain and Social Functioning. Patients with right hemiparesia improved more than those with left hemiparesia (p=0.02). CONCLUSION: FEO over a paretic leg is efficient to improve quality of life of stroke patients, mainly Physical Functioning.

Andersen syndrome (AS) is a rare disease characterized by the presence of periodic paralysis (PP), cardiac arrhythmia and dysmorphic abnormalities. We report herein the first Brazilian patient presenting AS who also had obesity, obstructive sleep apnea (OSA) and daytime sleepiness. Clinical and genetic evaluation of six family members demonstrated that four had dysmorphic abnormalities but none had PP or cardiac arrhythmia. Sequencing of KCNJ2 revealed the R218W mutation in the index patient and her 6-year-old daughter, who presented dysmorphic abnormalities (micrognathia, clinodactyly of fourth and fifth fingers, short stature) and OSA. Three relatives had clinodactyly as the only manifestation but the R218W mutation was absent, suggesting that this characteristic may be influenced by another gene. OSA accompanied by dysmorphic features may be related to AS.

Pharmacotherapy has been used as an adjunct to CPAP for treatment of residual excessive sleepiness in patients with a diagnosis of obstructive sleep apnea syndrome (OSAS). However, no studies with a high level of evidence have been conducted to support this practice and confirm its effectiveness. We conducted a meta-analysis to summarize and quantify the effects of pharmacological treatment in adults with OSAS who experience residual excessive sleepiness despite adequate CPAP use. We reviewed clinical trials that compared medications to placebo and evaluated the outcomes residual excessive sleepiness, cognition, and quality of life, as well as treatment effectiveness and safety. The MEDLINE, EMBASE, LILACS, Cochrane Central Register of Controlled Trials - CENTRAL, and PsycINFO electronic databases were searched using highly sensitive search strategies. Trials were only included if measures were taken to ensure effective CPAP treatment. Eight randomized clinical trials were included. Pharmacotherapy with modafinil and armodafinil led to improvement of excessive daytime sleepiness, attention/alertness, and clinical condition as measured with the CGI-C. No improvements in quality of life or other cognitive domains (including memory, executive function, and language) could be confirmed. Pharmacotherapy did not cause any severe adverse effects, but was associated with significant dropout rates as compared with placebo. In conclusion, although our results demonstrate the effectiveness of pharmacological treatment as an adjunct to CPAP, further investigation is necessary to improve confidence in its effects. Many findings on the impact of pharmacotherapy on cognition and quality of life were evaluated through analysis of single studies, with heterogeneity in tests and absence of standardization, which reduced certainty as to whether actual improvement occurred in these outcomes.

OBJECTIVE: To verify if nighttime feeding habits can influence parasomnia in children. METHOD: Seven private and four public Elementary Schools took part in the study. A total of 595 Sleep Disturbance Scale for Children were distributed to the parents of children aged from 7 to 8 years. Data of dietary recall, starting time to school, physical activity, and nutritional status were studied. RESULTS: Of the 226 questionnaires completed, 92 (41%) reported parasomnia. Girls had 2.3 times more the chance to parasomnia than boys. Children who consumed stimulant foods had 2.6 times more chance to have parasomnia than those of children who consumed non-stimulant foods. There were no difference between parasomnia and no-parasomnia groups in food type (p = 0.78) or timing of last meal before bedtime (p = 0.50). CONCLUSION: Our findings suggest that intake of stimulant foods is associated with development of parasomnia in children.
