Meta-Analysis
BACKGROUND
Gamma aminobutyric acid (GABA) receptor agonists have been shown to have a neuroprotectant effect in reducing infarct size and improving functional outcome in animal models of cerebrovascular disease. However, the sedative effects of GABA receptor agonists have limited their wider application in people with acute stroke, due to the potential risk of stupor. This is an update of a Cochrane Review first published in 2013, and previously updated in 2014 and 2016.
OBJECTIVES
To determine the efficacy and safety of GABA receptor agonists in the treatment of acute stroke.
SEARCH METHODS
We searched the Cochrane Stroke Group Trials Register (accessed May 2018), the Cochrane Central Register of Controlled Trials (CENTRAL) 2018, Issue 4 (accessed May 2018), MEDLINE (from 1949 to May 2018), Embase (from 1980 to May 2018), CINAHL (from 1982 to May 2018), AMED (from 1985 to May 2018), and 11 Chinese databases (accessed May 2018). In an effort to identify further published, unpublished, and ongoing trials we searched ongoing trial registers, reference lists, and relevant conference proceedings, and contacted authors and pharmaceutical companies.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) investigating GABA receptor agonists versus placebo for people with acute stroke (within 12 hours after stroke onset), with the primary outcomes of efficacy and safety.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened the titles and abstracts of identified records, selected studies for inclusion, extracted eligible data, cross-checked the data for accuracy, and assessed the risk of bias. We used the GRADE approach to assess the quality of the evidence.
MAIN RESULTS
We included five trials with 3838 participants (acute ischemic or hemorrhagic stroke patients, 3758 analyzed). Most of the participants recruited had acute ischaemic stroke, with limited data available from participants with other stroke subtypes, including total anterior circulation syndrome (TACS). The methodological quality of the included trials was generally good, with an unclear risk for selection bias only. For death and dependency at three months, pooled results did not find a significant difference for chlormethiazole versus placebo (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.96 to 1.11; four trials; 2909 participants; moderate-quality evidence) and for diazepam versus placebo (RR 0.94, 95% CI 0.82 to 1.07; one trial; 849 participants; moderate-quality evidence). The most frequent adverse events related to chlormethiazole were somnolence (RR 4.56, 95% CI 3.50 to 5.95; two trials; 2527 participants; moderate-quality evidence) and rhinitis (RR 4.75, 95% CI 2.67 to 8.46; two trials; 2527 participants; moderate-quality evidence).
AUTHORS' CONCLUSIONS
This review provides moderate-quality evidence that fails to support the use of GABA receptor agonists (chlormethiazole or diazepam) for the treatment of people with acute stroke. More well-designed RCTs with large samples of participants with total anterior circulation syndrome are required to determine if there are benefits for this subgroup. Somnolence and rhinitis are frequent adverse events related to chlormethiazole.

Review
The association of catatonia with epileptic seizures is a rare phenomenon that is poorly understood and needs more clinical research. This systematic review included all published case reports of patients with catatonia meeting ICD-11 criteria associated with epileptic seizures, published until December 2021 in PubMed. Case reports were synthesized and results were expressed as percentages. In total, 42 articles with 52 case reports were included. Most patients were adults with a dispersed age (mean age 44.9 ± 19.3), slightly more males (59.6 %), with psychiatric history (76.9 %) of affective disorders (26.9 %) or psychotic episodes (13.5 %) and/or neurological history (61.5 %) of epileptic seizures (38.5 %) or head trauma (13.5 %). Their clinical presentation consisted mostly of decreased psychomotor activity (mutism: 94.2 %; stupor: 78.8 %; staring: 57.7 %; negativism: 36.5 %) with some abnormal psychomotor activity (catalepsy: 40.4 %; rigidity: 40.4 %; waxy flexibility: 23.1 %; posturing: 21.2 %) and half had clinical epileptic seizures (51.9 %), mostly generalized tonic-clonic (23.1 %). Almost all electroencephalograms (97.9 %) and half of brain imaging exams (47.4 %) performed had abnormal findings. The epileptic activity was mainly generalized (50 %) and associated with primary epilepsy (30.8 %), iatrogenesis (23.1 %), other secondary aetiologies (25 %) or unknown causes (21.2 %). Most improved with antiepileptic therapy (87.5 %) and had a complete remission (86.5 %). Catatonia secondary to epileptic seizures often has a nonspecific clinical presentation and appears in patients with previous psychiatric diagnoses, so any patient with catatonia should be properly investigated to avoid misdiagnosis and ineffective treatments.

INTRODUCTION
Excessive water intake is rarely associated with life-threatening hyponatraemia. The aim of this study was to determine the clinical characteristics and outcomes of hyponatraemia associated with excess water intake.
METHODS
This review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All studies (case reports, observational or interventional studies) reporting excess water intake and hyponatraemia in adults (1946-2019) were included.
RESULTS
A total of 2970 articles were identified and 177 were included (88.7% case reports), consisting of 590 patients. The mean age was 46±16 years (95% CI 44 to 48 years), 47% female, 52% had a chronic psychiatric disorder and 31% had no underlying condition. The median volume of water consumed and serum sodium at presentation was 8 L/day (95% CI 8.9 to 12.2 L/day) and 118 mmol/L (95% CI 116 to 118 mmol/L), respectively. The motivator for increased water consumption was psychogenic polydipsia (55%); iatrogenic (13%); exercise (12%); habitual/dipsogenic polydipsia (7%) and other reasons (13%). The clinical features on presentation were severe in 53% (seizures, coma); moderate in 35% (confusion, vomiting, agitation) and mild in 5% (dizziness, lethargy, cognitive deficit) and not reported in 5% of studies. Treatment was supportive in 41% of studies (fluid restriction, treatment of the underlying cause, emergency care), and isotonic and hypertonic saline was used in 18% and 28% of cases, respectively. Treatment-related complications included osmotic demyelination (3%) and rhabdomyolysis (7%), and death occurred in 13% of cases.
CONCLUSION
Water intoxication is associated with significant morbidity and mortality and requires daily intake to substantially exceed population-based recommendations. The limitations of this analysis are the low quality and high risk of bias of the included studies.

Review
Alcohol and Sedative-Hypnotic Withdrawal Catatonia: Two Case Reports, Systematic Literature Review, and Suggestion of a Potential Relationship With Alcohol Withdrawal Delirium.
BACKGROUND
Withdrawal from alcohol and sedative-hypnotics can be complicated by seizures, hallucinations, or delirium. Withdrawal catatonia is another, less commonly discussed complication that clinicians should appreciate.
METHODS
We present a case of alcohol withdrawal catatonia and a case of benzodiazepine withdrawal catatonia and offer a systematic review of previous cases of alcohol or sedative-hypnotic withdrawal catatonia. We outline clinical features that suggest a potential link between withdrawal catatonia and withdrawal delirium.
RESULTS
We identified 26 cases of withdrawal catatonia in the literature-all principally with catatonic stupor-with an average age of 56 years (range: 27-92) and balanced prevalence between sexes. Withdrawal catatonia tends to occur only after chronic use of alcohol or sedative-hypnotic agents with a typical onset of 3-7 days after discontinuation and duration of 3-10 days. Withdrawal catatonia is responsive to benzodiazepines or electroconvulsive therapy. Features that suggest a parallel between withdrawal catatonia and withdrawal delirium include time course, neurobiologic convergence, efficacy of benzodiazepines and electroconvulsive therapy, typical absence of abnormal electroencephalographic findings, and phenotypic classification suggested by a recent literature in sleep medicine.
CONCLUSION
Alcohol and sedative-hypnotic withdrawal may present with catatonia or catatonic features. The clinical and neurobiologic convergence between withdrawal catatonia and withdrawal delirium deserves further attention. In view of these similarities, we propose that withdrawal delirium may represent excited catatonia: these new viewpoints may serve as a substrate for a better understanding of the delirium-catatonia spectrum.

BACKGROUND
Direct current (DC) powered equipment and devices, including photovoltaic systems, high-voltage direct current power lines and novel concepts in electromobility have become increasingly popular in recent years. However, under adverse circumstances by malfunction or mishandling of these applications electrical injuries may occur when electric current passes through the human body. This review aimed at systematically summarizing the medical consequences of DC electrical injuries described in case reports and case series.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guided the methodological conduct and reporting.
RESULTS
Sixteen case reports and 3 case series were eligible for this review and included 70 patients. The reviewed articles were very heterogeneous regarding sources of DC electrical injuries and the reported medical consequences, including burns and skin lesions (n=67), neurological consequences (n=11), unconsciousness (n=10), cardiac consequences (n=8) and bone fractures (n=6). Seventeen individuals did not survive the electrical injuries.
CONCLUSION
From the few available data and partly incomplete documentations of cases we could gather hints of DC medical consequences, however, it was not possible to identify well-defined medical consequences for various circumstances of DC electrical injuries in occupational and non-occupational settings. To achieve this goal, additional studies are required, each providing a comprehensive description of the medical consequences and the circumstances of the electrical injuries.

Meta-Analysis
AIM
To systematically evaluate the medication safety and effectiveness of Oxcarbazepine (OXC) and carbamazepine (CBZ) for the treatment of post-stroke epilepsy (PSE).
MATERIAL AND METHODS
We searched Medline and other databases to identify the randomized controlled trials (RCTs) that compare the efficacies of OXC and CBZ in treating PSE. Two authors extracted and analyzed the data independently with Revman 5.3 software. The Q-test and I2 were used to test the statistical heterogeneity. The fixed or random effect models were selected according to heterogeneity.
RESULTS
Eight RCTs that include 671 patients were involved in this study. The meta-analyses result showed that the overall efficiency of OXC was significantly better than that of CBZ (OR=4.55, 95% confidence interval (CI) (3.04?6.81)), the overall adverse events (OR=0.27, 95% CI (0.18?0.42), and the incidence of vomiting (OR=0.28, 95% CI (0.09?0.85)) of OXC was significantly less than that of CBZ. No significant differences in the incidence of rash (OR=0.45, 95% CI (0.19?1.07)), lethargy (OR=0.49, 95% CI (0.16?1.45)), and dizziness (OR=0.51, 95% CI (0.20?1.35)) were detected between OXC and CBZ.
CONCLUSION
OXC seems to be superior to CBZ in the treatment of PSE, with higher efficacy, and safety than the latter. However, more research on OXC and CBZ in the treatment of PSE is required in the later stage due to the sample size limitation of our study.

Review
OBJECTIVE
To ascertain the presence of catatonia in cases of pediatric postoperative cerebellar mutism syndrome (PPCMS).
METHOD
A systematic review of PPCMS case reports of patients aged 0-17 years with sufficient clinical information to extract catatonic phenomena was undertaken following PRISMA guidelines. Standardized catatonia rating scales were applied to selected cases retrospectively to ascertain whether diagnostic criteria for catatonia were met. A case known to the authors is also presented.
RESULTS
Two hundred twenty-one suitable full-text articles were identified. Following screening and application of inclusion criteria, 51 articles were selected plus seven more from their references, reporting on 119 subjects. All cases met Bush and Francis (BF) diagnostic criteria for catatonia, 92.5% Pediatric Catatonia Rating Scale (PCRS), 52.9% ICD-11, and 44.5% DSM-5. All patients presented with mutism. The next most frequent signs were immobility/stupor (77.3%), withdrawal (35.3%), mannerisms (23.5%), and excitement/agitation (18.5%). Most cases presented with stuporous catatonia (75.6%). Catatonia most frequently occurred following resection of medulloblastoma (64.7%). Preoperative hydrocephalus occurred in 89 patients (74.8%).
CONCLUSION
Catatonia was frequent in this PPCMS sample, with a predominant stuporous variant; it should be considered in patients with PPCMS and assessed with reliable and validated instruments for prompt diagnosis and management.

Review
Equine granulocytic anaplasmosis (EGA) is a tick-borne disease affecting horses worldwide, caused by . The disease ranges from non-specific clinical signs to fatal outcomes. This paper aimed to analyze EGA cases reported in peer-reviewed journals, particularly on clinico-pathological findings, diagnosis, and therapeutic management. Overall, 189 clinical cases from 31 publications were included in the study. Extensive symptomatology for the EGA cases was reported, of which mostly was fever (90.30%), followed by limb edema (48.51%), anorexia (41.79%), depression (32.84%), icterus (22.39%), ataxia (17.91), tachycardia (16.42%), and lethargy (15.67%). Laboratory tests revealed thrombocytopenia (90.32%), anemia (75%), decreased hematocrit (70.59%), leukopenia (55.88%), lymphopenia (58.14%), and neutropenia (41.67%) as the most common hematological abnormalities. For a subset of tested animals, hyperbilirubinemia (20/29), hyperfibrinogenemia (13/15), and hyponatremia (10/10) were also reported. The diagnosis was established by microscopic identification of morulae (in 153 cases), and/or PCR (120 cases), isolation (1 case), or serology (56 cases). For treatment, oxytetracycline was used in the majority (52.24%) of EGA cases, but recovery without antibiotherapy (10.34%) was also noted. In conclusion, the variety of clinical and pathological findings and the challenging therapeutic approaches reported suggest that EGA should be included in the differential diagnosis when fever occurs.

Meta-Analysis
BACKGROUND
It is necessary to conduct a meta-analysis of the clinical randomized controlled trials (RCTs) on ropinirole in the treatment of Parkinson disease (PD), to explore the effects and safety of ropinirole, and to provide a theoretical basis for clinically safe and rational drug use.
METHODS
RCTs on the effectiveness and safety of ropinirole in the treatment of PD were searched. We searched Dutch medical literature database, Pubmed, Cochrane Library, China National Knowledge Infrastructure, Wanfang Knowledge Service Platform up to December 15, 2020. The Cochrane risk bias assessment tool was used to evaluate the quality of the included literature, and the RevMan5.3 software was used for meta-analysis.
RESULTS
A total of 12 RCTs with 3341 patients were included. The changes of Parkinson Disease Rating Scale Part II score (mean difference = -2.23, 95% confidence interval [CI] -2.82 to -1.64) and Parkinson Disease Rating Scale Part III scores (mean difference = -4.93, 95%CI -5.25 to -4.61) in the ropinirole group was significantly lower than that in the control group. The incidence of dizziness (odd risk [OR] = 1.85, 95%CI 1.50-2.28), nausea (OR = 2.17, 95%CI 1.81-2.59), vomiting (OR = 2.73, 95%CI 1.47-5.09), and lethargy (OR = 2.19, 95%CI 1.39-3.44) in the ropinirole group was significantly higher than that in the control group (all P < .05), and there were no significant differences in the incidence of headache (OR = 1.14, 95%CI 0.79-1.65) and insomnia (OR = 1.06, 95%CI 0.72-1.55) were found between 2 groups (all P > .05).
CONCLUSIONS
Ropinirole can help improve the ability of daily living and exercise function of PD patients, but it will increase the incidence of related adverse reactions, which needs to be further confirmed by subsequent large-scale, high-quality RCTs.

Meta-Analysis
In recent years, outbreaks of hand-foot-mouth disease (HFMD) in China, Singapore and other Western Pacific Region, involving millions of children, have become a big threat to public health. This study aimed to quantitatively assess all qualified studies and identify the risk factors for HFMD death. A systematic search of the databases PubMed, Medline, Embase and the Cochrane Library was performed. Study heterogeneity and publication bias were estimated. Seven case-control studies involving 1641 participants (634 died and 1007 survived) were included in the meta-analysis. Human enterovirus 71 infection, male, age ⩽3 years, vomiting, cyanosis, convulsion, duration of fever ⩾3 days, atypical rashes and abdominal distention were not significantly related to HFMD death (P ⩽ 0.05). Lethargy (odds ratio (OR) = 6.62; 95% CI 3.61-12.14; I2 = 0%; P < 0.0001), pneumonoedema/pneumorrhagia (OR = 4.09; 95% CI 2.44-6.87; I2 = 0%; P < 0.0001), seizures (OR = 6.85; 95% CI 2.37-19.74; I2 = 0%; P = 0.0004), dyspnoea (OR = 8.24; 95% CI 2.05-33.19; I2 = 83%; P = 0.003) and coma (OR = 3.76; 95% CI 1.85-7.67; I2 = 0%; P = 0.0003) were significantly associated with HFMD death, which were risk factors for HFMD death.
