Meta-Analysis
BACKGROUND
Ischemic stroke significantly contributes to high mortality and disability rates. Cerebral edema is a common consequence of ischemic stroke and can lead to aggravation or even death. Current treatment strategies are limited to decompressive craniectomy and the intravascular administration of hypertonic drugs, which have significant side effects. Acetazolamide (ACZ) plays a therapeutic role in cerebral edema by inhibiting aquaporin-4 (AQP-4) and improving collateral circulation. This study aimed to perform a meta-analysis and systematic review of ACZ therapy for ischemic stroke and evaluate its efficacy in animal models.
METHODS
We searched Embase, Cochrane Library, PubMed, Web of Science, Chinese National Knowledge Infrastructure, Wanfang Database, and Chinese Biomedical Literature Database until April 2023 for studies on ACZ in ischemic animal models. The quality of the animal trials was assessed using the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Stroke.
RESULTS
After screening 376 articles, only 5 studies were included. We found that ACZ reduced brain edema in cerebral ischemia 24 hours after onset (standard mean difference, -2.00; 95% confidence interval, -3.57 to -0.43, P = 0.01). ACZ also inhibited AQP-4 expression 24 hours after onset (standard mean difference-1.46; 95% confidence interval, -2.01 to -0.91, P < 0.001). Brain edema and AQP-4 expression also showed a declining trend on the third day after onset, although there were not enough data to support this. The effect of ACZ on brain ischemia in animals' neurological function is uncertain because of the limited research data.
CONCLUSIONS
ACZ inhibited AQP-4 and alleviated brain edema after ischemic stroke in the early stages but seemingly could not improve the neurological function.

BACKGROUND
Although phenytoin's potential benefits in wound healing, pain relief, and infection control across various wound types have been previously reported, its use in wound care remains limited.
OBJECTIVE
To conduct a comprehensive review to assess the efficacy of topical phenytoin compared with standard and alternative treatments for different wound types.
MATERIALS AND METHODS
The authors last searched Cochrane Library, PubMed, PubMed Central, and MEDLINE in June 2023. All English-language human RCTs and NRCTs from any time were included. The RoB 2 was used to assess quality of randomized trials, and the ROBINS-I was used to assess the quality of nonrandomized trials. Studies with a low risk of bias or some concerns in no more than 1 domain were included. Data collected and analyzed included wound type, interventions, sample size, outcome measures, and adverse effects.
RESULTS
The search yielded 101 studies, of which 17 RCTs and 8 NRCTs were eligible for inclusion. Of the included studies, 56% had a low risk of bias in all domains. The sample sizes varied between 20 and 130 (median, 60), with a total sample size of 1653 patients. Phenytoin improved wound healing in 17 of the 24 studies that evaluated it (71%), increased granulation tissue in 9 of the 10 studies that evaluated it (90%), provided analgesic effects in 7 of the 13 studies that evaluated it (54%), and inhibited bacterial contaminants in 6 of the 8 studies that evaluated it (75%). Adverse effects were rare (29%), minimal, and transient.
CONCLUSION
Phenytoin enhances wound healing and offers analgesic and antibacterial properties with minimal adverse effects. Further research is needed on optimal dosage of phenytoin, as well as frequency, delivery vehicles, and effects on other postoperative wounds.

European Journal of Clinical... Jan 2024This study intends to assess the reference range of lamotrigine concentration for treating childhood epilepsy. (Review)
Review
PURPOSE
This study intends to assess the reference range of lamotrigine concentration for treating childhood epilepsy.
METHODS
PubMed, Ovid-Embase, The Cochrane Library, CNKI, WanFang data and VIP databases were searched from database inception to January 2022. RCT, cohort study, case-control study, cross-sectional study that estimated the reference range of lamotrigine for children epilepsy treatment were included. The data extracted included basic information, statistical methods, data type, and results of reference range. Descriptive analysis was performed for them.
RESULTS
8 studies were included and estimated the reference range, and all of them were calculated based on efficacy data and/or concentration data. Statistical methods including ROC curve, concentration-effect curve, mean ± standard deviation, 95% confidence interval and percentile interval were utilized. For lamotrigine monotherapy, the lower limits ranged from 2.06 mg/L to 3.99 mg/L, and the upper limits ranged from 8.43 mg/L to 9.08 mg/L, showing basic consistency. However, for lamotrigine concomitant with valproate, the lower limits ranged from 2.00 mg/L to 8.00 mg/L, and the upper limit was 11.50 mg/L, for lamotrigine concomitant with other antiepileptics, the lower limits ranged from 1.00 mg/L to 3.09 mg/L, and the upper limits varied from 5.90 mg/L to 16.24 mg/L, indicating inconsistency.
CONCLUSION
Several studies have estimated the reference range of lamotrigine for childhood epilepsy, while controversy exist and no studies have determined the upper limit of the range based on safety data. To establish the optimal reference range, further high-quality studies are necessary that consider both efficacy and safety data.

Review
INTRODUCTION
Epilepsy is one of the most frequent neurological comorbidities in patients with Down Syndrome (DS). Young patients and adults are the most affected, the latter mostly showing a phenotype labeled as "Late-onset myoclonic epilepsy" (LOMEDS). Status epilepticus (SE) is a life-threatening complication in patients with epilepsy. In this study, we described a non-convulsive SE (NCSE) case in a patient diagnosed with LOMEDS. We also performed a systematic review of the literature on SE diagnosis and treatment in patients with Down Syndrome.
METHODS
Clinical and demographic characteristics of a DS patient diagnosed with NCSE were described. The systematic literature search dissected the diagnostic and therapeutic management of SE in patients with DS. The following databases were used: PubMed, EMBASE, and Google Scholar.
RESULTS
5 DS individuals (4 from the past literature + 1 novel case report) with SE have been identified. The median age at SE onset was 42 years (IQR: 21-60.5 years). The most common SE type was myoclonic SE (MSE), followed by NCSE. Two cases of acute symptomatic etiology were described, whereas a progressive symptomatic etiology was otherwise reported. Ictal EEG recording information was available in two patients who showed generalized spike waves and polyspike and wave discharges. In 3 cases, SE was treated with intravenous antiseizure medications that produced a complete resolution.
CONCLUSION
SE may represent a rare complication in patients with DS. Although no definitive conclusions may be achieved due to the lack of evidence, treatment with valproic acid seems effective, especially in MSE. NCSE management is more challenging. It requires low doses of anesthetics, which should be used cautiously due to the high rate of complications.

Journal of Cardiothoracic Surgery Jun 2024Systematic evaluation of the safety of del Nido cardioplegia compared to cold blood cardioplegia in adult cardiac surgery. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
Systematic evaluation of the safety of del Nido cardioplegia compared to cold blood cardioplegia in adult cardiac surgery.
METHODS
We systematically searched PubMed, EMbase, The Cochrane Library and ClinicalTrials.gov for randomized clinical trials (published by 14 January 2024) comparing del Nido cardioplegia to cold blood cardioplegia in adult. Our main endpoints were myocardial injury markers and clinical outcomes. We assessed pooled data by use of a random-effects model or a fixed-effects model.
RESULTS
A total of 10 studies were identified, incorporating 889 patients who received del Nido cardioplegia and 907 patients who received cold blood cardioplegia. The meta-analysis results showed that compared with the cold blood cardioplegia, the del Nido cardioplegia had less volume of cardioplegia, higher rate of spontaneous rhythm recovery after cross clamp release, lower levels of postoperative cardiac troponin T and creatinine kinase-myocardial band, all of which were statistically significant. However, there was no statistically significant difference in postoperative troponin I and postoperative left ventricular ejection fraction. The clinical outcomes including mechanical ventilation time, intensive care unit stay time, hospital stay time, postoperative stroke, postoperative new-onset atrial fibrillation, postoperative heart failure requiring intra-aortic balloon pump mechanical circulation support, and in-hospital mortality of both are comparable.
CONCLUSION
Existing evidence suggests that del Nido cardioplegia reduced volume of cardioplegia administration and attempts of defibrillation. The superior postoperative results in CTnT and CK-MB may provide a direction for further research on improvement of the composition of cardioplegia.

BACKGROUND
Seizures are an important palliative symptom, the management of which can be complicated by patients' capacity to swallow oral medications. In this setting, and the wish to avoid intravenous access, subcutaneous infusions may be employed. Options for antiseizure medications that can be provided subcutaneously may be limited. Subcutaneous sodium valproate may be an additional management strategy.
AIM
To evaluate the published experience of subcutaneous valproate use in palliative care, namely with respect to effectiveness and tolerability.
DESIGN
A systematic review was registered (PROSPERO CRD42023453427), conducted and reported according to PRISMA reporting guidelines.
DATA SOURCES
The databases PubMed, EMBASE and Scopus were searched for publications until August 11, 2023.
RESULTS
The searches returned 429 results, of which six fulfilled inclusion criteria. Case series were the most common study design, and most studies included <10 individuals who received subcutaneous sodium valproate. There were three studies that presented results on the utility of subcutaneous sodium valproate for seizure control, which described it to be an effective strategy. One study also described it as an effective treatment for neuropathic pain. The doses were often based on presumed 1:1 oral to subcutaneous conversion ratios. Only one study described a local site adverse reaction, which resolved with a change of administration site.
CONCLUSIONS
There are limited data on the use of subcutaneous sodium valproate in palliative care. However, palliative symptoms for which subcutaneous sodium valproate have been used successfully are seizures and neuropathic pain. The available data have described few adverse effects, supporting its use with an appropriate degree of caution.

Meta-Analysis Review
BACKGROUND
Prior research has established the effectiveness of magnesium in relieving postoperative pain. This article aims to evaluate magnesium sulfate for perioperative analgesia in adults undergoing general abdominal surgery under general anesthesia.
OBJECTIVE
The primary aim was to assess pain scores at 6 and 24 hours postoperatively in patients receiving magnesium sulfate vs. the control group. Secondary outcomes were postoperative opioid consumption, perioperative complications, and time to rescue analgesia.
METHODS
A comprehensive database search identified studies comparing magnesium sulfate with control in adults undergoing general anesthesia for general abdominal surgery. Using random-effects models, data were presented as mean ± Standard Deviation (SD) or Odds Ratios (OR) with corresponding 95% Confidence Intervals (95% CI). A two-sided p-value < 0.05 was considered statistically significant.
RESULTS
In total, 31 studies involving 1762 participants met the inclusion criteria. The magnesium group showed significantly lower postoperative pain scores at both early (within six hours) and late (up to 24 hours) time points compared to the control group. The early mean score was 3.1 ± 1.4 vs. 4.2 ± 2.3, and the late mean score was 2.3 ± 1.1 vs. 2.7 ± 1.5, resulting in an overall Mean Difference (MD) of -0.72; 95% CI -0.99, -0.44; p < 0.00001. The magnesium group was associated with lower rates of postoperative opioid consumption and shivering and had a longer time to first analgesia administration compared to the saline control group.
CONCLUSION
Magnesium sulfate administration was linked to reduced postoperative pain and opioid consumption following general abdominal surgery.

OBJECTIVES
To systematically review the existing literature for evidence of efficacy around interventions in the management of persistent pain post radiotherapy for head and neck cancers.
METHODS
A systematic review of the literature was conducted to assess the effectiveness and safety of interventions for the management of persistent post-radiotherapy pain in head and neck cancers. The primary outcome evaluated whether an intervention resulted in a reduction in pain which was determined using validated pain tools.
RESULTS
Two randomised controlled trials involving 196 participants fulfilled the inclusion criteria, one evaluating the effect of hypnotherapy and the other evaluating the effect of pregabalin on radiotherapy related pain in head and neck cancer patients. In one study by Thuma et al. (2016) there was a decrease in pain scores in the hypnotherapy group (p<0.001). In the other study, by Jiang et al. (2018) patients treated with pregabalin had a greater reduction in pain intensity, pain severity and a reduction in pain functional interference (p<0.001).
CONCLUSIONS
The findings of our review suggest that in chronic post-radiotherapy pain for head and neck cancers there is very-low level evidence for the use of hypnotherapy in reducing pain scores and for the use of pregabalin in reducing pain intensity, severity, functional interference and psychological distress with significant improvement in quality of life.

Meta-Analysis
BACKGROUND
The relationship between epilepsy and depression is bidirectional. One condition exacerbates the other. However, there are no current guidelines for treating depression in epilepsy patients. In some cases, seizures worsen when antidepressants (AD) are prescribed or when they are discontinued due to adverse events. The Shugan Jieyu capsule, composed of Acanthopanax senticosus and Hypericum perforatum, is a widely used herbal medicine for treating depression. This study aimed to explore the effectiveness and safety of Shugan Jieyu capsules (SJC) in relieving depression in patients with epilepsy.
METHODS
We searched English, Korean, Japanese, and Chinese databases in October 2023 to collect all relevant randomized clinical trials (RCTs). The primary outcomes were the depression scale scores and seizure frequency. The secondary outcomes were quality of life (QoL) and adverse events.
RESULTS
Nine RCTs were included in this meta-analysis. Compared with AD, SJC showed significant differences in the improvement of depression (SMD: 3.82, 95% CI: 3.25, 4.39) and reduction in seizure frequency (MD: 0.39 times/month, 95% CI: 0.28, 0.50). SJC showed more beneficial results than antiepileptic drugs (AED) in terms of antidepressant effects (SMD: 1.10, 95% CI: 0.69, 1.51) and QoL (MD: 11.75, 95% CI: 10.55, 12.95). When patients were prescribed AED, the additional administration of SJC improved depression symptoms (SMD: 0.96, 95% CI: 0.28, 1.63). The SJC treatment group had a lower incidence of side effects than the control group. However, the difference was not statistically significant.
CONCLUSIONS
Our results suggest that SJC may be effective in treating depression in patients with epilepsy. Additionally, SJC has the potential to help reduce seizure frequency in epilepsy patients with depression.

BACKGROUND
Local anesthetic systemic toxicity (LAST) is rare, but fatal; the current widely used treatment is lipid emulsion (LE). The goal of this study was to analyze and review case reports on LE treatment for LAST in pediatric patients.
METHODS
We performed a systematic review using case reports on LE treatment for LAST in pediatric patients, searching PubMed and Scopus databases to March 2023 using the following keywords: ("local anesthetic toxicity" OR "local anesthetic systemic toxicity" OR LAST") AND ("newborn" OR "infant" OR "child" OR "children" OR "adolescent" OR "pediatric") AND ("lipid emulsion" OR "Intralipid").
RESULTS
Our search yielded 21 cases, revealing that nearly 43% patients with LAST were less than 1 year old, and most cases were caused by bupivacaine (approximately 67% cases). "Inadvertent intravascular injection" by anesthesiologists and "overdose of local anesthetics" mainly by surgeons were responsible for 52% and 24% cases of LAST, respectively. LAST occurred in the awake state (52%) and under general anesthesia (48%), mainly causing seizures and arrhythmia, respectively. Approximately 55% of patients received LE treatment in <10 minutes after LAST, mainly improving cardiovascular symptoms. A 20% LE (1.5 mL/kg) dose followed by 0.25 mL/kg/minutes dose was frequently used. LE and anticonvulsants were mainly used in the awake state, whereas LE with or without vasopressors was mainly used under general anesthesia. LE treatment led to full recovery from LAST in 20 cases; however, 1 patient died due to underlying disease.
CONCLUSION
Consequently, our findings reveal that LE is effective in treating pediatric LAST.
