OBJECTIVE: To determine the efficacy and safety of intravenous single dose lidocaine versus single dose propofol in controlling emergence agitation in children aged 2-6 years old for surgery under sevoflurane anesthesia in Philippine Children’s Medical Center. MATERIALS AND METHODS: This was a double-blind, randomized controlled trial of 64 children aged 2-6 years who had surgery under general anesthesia using sevoflurane. Patients were randomly assigned into 2 equal groups – the experimental (Lidocaine, L) group and the control (Propofol, P) group. Five (5) minutes prior to the discontinuation of sevoflurane, the patient assigned to the L group was given Lidocaine at 1.5 mg/kg IV while the patient assigned to the P group was given Propofol 1 mg/kg IV. Patients were monitored using Pediatric Anesthesia Emergence Delirium (PAED) and Face, Legs, Activity, Cry, and Consolability (FLACC) scales 5 minutes after giving the medication until discharge from the PACU. Data was collected using a data abstraction form. RESULTS: There were no statistically significant differences between the 2 groups in terms of emergence agitation (RR= 0.5, 95% CI [0.098, 2.54], pvalue= 0.672) and post- operative pain (RR:0.6, 95% CI [0.033, 1.91], pvalue = 0.426). No adverse events were observed in both groups. CONCLUSION Both Lidocaine and Propofol are effective in preventing emergence agitation.

Lung cancer is the leading cause of cancer death worldwide. It may present as airway obstruction in a patient with endobronchial masses. Endobronchial brachytherapy (EBBT) has been shown to provide palliative therapy. It is the insertion of a radioactive material near the mass to reduce tumor size, thereby improving airway obstruction. This is the first case of EBBT done in our institution during the COVID-19 pandemic. A 53-year-old male, 60 kg, ASA Physical Status 2 for hypertension, smoker, malignancy, and previous pulmonary tuberculosis patient, presented with a cough and dyspnea. An endobronchial mass almost obstructing the right mainstem bronchus was seen on a computed tomography (CT) scan. He was diagnosed with squamous cell carcinoma of the lung and underwent radiotherapy and erlotinib chemotherapy. On repeat CT scan, there was no noted decrease in the size of the mass. EBBT was suggested, and a multi-disciplinary team was formed for the planned procedure. Pulmonology, radiation oncology, and anesthesiology teams were identified, and thorough planning was done prior to the actual procedure. Three fractions of EBBT were done under sedation using midazolam, fentanyl, and dexmedetomidine infusion. Lidocaine spray and transtracheal block were also performed as adjuncts prior to sedation. The procedure went as planned, and points for improvement were discussed for subsequent fractions. Due to persistent cough and discomfort from the catheter, additional ipratropium nebulization for minimization of secretions, and oral dextromethorphan for cough suppression were incorporated. After each fraction, the patient was monitored post-procedure for any side effects both from the radiotherapy and anesthetic technique. Qualitative reduction in mass size was noted in subsequent fractions. The patient was able to complete 3 fractions and was advised to follow-up after a month. EBBT is an emerging palliative and treatment modality for lung cancer, especially for intraluminal masses. Anesthetic considerations will depend on each case’s characteristics such as airway anatomy, patient comfort and capacity, and procedural requirements. Conscious sedation with topical anesthesia is an adequate and appropriate anesthetic option, especially in cases where severe airway obstruction may compromise ventilation if airway reflexes are blunted. A multidisciplinary approach with different services and stakeholders is important for the proper planning, execution, and management of such patients.

BACKGROUND: Emergence delirium is a state of mental confusion and agitation after wakening from anesthesia that may result in traumatic injuries to the child. Limited drugs have been studied or used to prevent this occurrence. OBJECTIVE: To determine the efficacy and safety of intravenous lidocaine in controlling emergence agitation (EA) in children undergoing surgeries done under general anesthesia compared to placebo or other intravenous anesthetics. METHODOLOGY: This study is a meta-analysis, where published articles were obtained using PubMed, Cochrane Library, Clinical Trials, and Google Scholar up to August 2022. The primary outcome measure includes incidence of emergence delirium while secondary outcomes are postoperative pain and adverse effects comparing lidocaine and other intravenous drugs. The latter includes nausea and vomiting, untoward airway events and local anesthetic toxicity (LAST). Review Manager 5.4 was used for statistical analysis. RESULTS: There were a total of 6 articles included for quantitative and qualitative analysis. The overall incidence of emergence agitation (RR=1.03, 95% CI [0.50, 2.13], P=0.94) and adverse events were higher in the Lidocaine group, although the differences were not significant. Subgroup analysis by comparator showed significant increased risk of developing EA with Lidocaine compared to other intravenous drugs (RR=2.06, 95% CI [1.32, 2.32], P=0.002). The risk for developing postoperative pain is decreased with Lidocaine compared to placebo and other drugs. CONCLUSION Intravenous lidocaine given to children undergoing general anesthesia with sevoflurane increased their risk for emergence delirium, compared to both placebo and other intravenous anesthetics.

This study systematically reviewed the clinical efficacy of acupuncture for lumbar myofascial pain syndrome. The randomized controlled trials (RCTs) regarding acupuncture for lumbar myofascial pain syndrome were searched in PubMed, Cochrane Library, Web of Science, EMbase, Scopus, China national knowledge infrastructure (CNKI), Wanfang database, VIP database, and China biomedical literature service system (SinoMed) from database inception until August 1st, 2022. The Cochrane's risk of bias assessment tool was used to assess the risk of bias in all included studies, and Review Manager 5.3 software was used for statistical analysis of the extracted data. As a result, 12 RCTs, involving 1 087 patients with lumbar myofascial pain syndrome, were ultimately included. The Meta-analysis results showed that the visual analog scale (VAS) score of pain in the observation group was lower than those in the oral non-steroidal anti-inflammatory medication control [SMD=-1.67, 95%CI (-2.44, -0.90), Z=4.26, P<0.000 1] and other treatment control [low-frequency electrical stimulation, tuina, electromagnetic wave irradiation combined with piroxicam gel, SMD=-1.98, 95%CI (-2.48, -1.48), Z=7.74, P<0.000 01]. The pain rating index (PRI) score in the observation group was lower than those in the lidocaine injection control [MD=-2.17, 95%CI (-3.41, -0.93), Z=3.44, P=0.000 6] and other treatment control [low-frequency electrical stimulation, tuina, MD=-5.75, 95%CI (-9.97, -1.53), Z=2.67, P=0.008]. The present pain intensity (PPI) score in the observation group was lower than that in other treatment control [low-frequency electrical stimulation, tuina, MD=-1.04, 95%CI (-1.55, -0.53), Z=4.01, P<0.000 1]. In conclusion, compared with oral non-steroidal anti-inflammatory medication, low-frequency electrical stimulation, tuina, and electromagnetic wave irradiation combined with piroxicam gel, acupuncture is more effective in reducing pain in patients with lumbar myofascial pain syndrome; acupuncture also exhibites advantage over lidocaine injection in improving PRI score and showed better outcomes over tuina and low-frequency electrical stimulation in improving PRI and PPI scores.

This study aims to observe the effect of chlorogenic acid(CGA) on microRNA(miRNA) in the process of protecting against N-acetyl-p-aminophenol(APAP)-induced liver injury. Eighteen C57BL/6 mice were randomly assigned into a normal group, a model group(APAP, 300 mg·kg~(-1)), and a CGA(40 mg·kg~(-1)) group. Hepatotoxicity of mice was induced by intragastric administration of APAP(300 mg·kg~(-1)). The mice in the CGA group were administrated with CGA(40 mg·kg~(-1)) by gavage 1 h after APAP administration. The mice were sacrificed 6 h after APAP administration, and plasma and liver tissue samples were collected for the determination of serum alanine/aspartate aminotransferase(ALT/AST) level and observation of liver histopathology, respectively. MiRNA array combined with real-time PCR was employed to discover important miRNAs. The target genes of miRNAs were predicted via miRWalk and TargetScan 7.2, verified by real-time PCR, and then subjected to functional annotation and signaling pathway enrichment. The results showed that CGA administration lowered the serum ALT/AST level elevated by APAP and alleviate the liver injury. Nine potential miRNAs were screened out from the microarray. The expression of miR-2137 and miR-451a in the liver tissue was verified by real-time PCR. The expression of miR-2137 and miR-451a was significantly up-regulated after APAP administration, and such up-regulated expression was significantly down-regulated after CGA administration, consistent with the array results. The target genes of miR-2137 and miR-451a were predicted and verified. Eleven target genes were involved in the process of CGA protecting against APAP-induced liver injury. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment with DAVID and R language showed that the 11 target genes were enriched in Rho protein-related signal transduction, vascular patterning-related biological processes, binding to transcription factors, and Rho guanyl-nucleotide exchange factor activity. The results indicated that miR-2137 and miR-451a played an important role in the inhibition of CGA on APAP-induced hepatotoxicity.

Acetaminophen (APAP) is the most common antipyretic, analgesic and anti-inflammatory drug, but its overdose often leads to acute liver injury, even acute liver failure, and death in some severe cases. At present, there is still a lack of specific treatments. The c-Jun N-terminal kinase (JNK) signal pathway is one of the potential therapeutic targets identified in recent years in overdose APAP-induced acute liver injury. This article reviews the JNK signaling pathway of APAP in liver metabolism, the activation of JNK signaling pathway and the amplification of oxidative stress, other pathways or cellular processes related to JNK signaling pathway, and the possible challenges of drugs targeting JNK, so as to provide direction and feasibility analysis for further research and clinical application of JNK signaling pathway targets in APAP hepatotoxicity, and to provide reference for searching for other targets.

OBJECTIVE: To establish a snail control approach for spraying chemicals with drones against Oncomelania hupensis in complex snail habitats in hilly regions, and to evaluate its molluscicidal effect. METHODS: The protocol for evaluating the activity of spraying chemical molluscicides with drones against O. hupensis snails was formulated based on expert consultation and literature review. In August 2022, a pretest was conducted in a hillside field environment (12 000 m²) north of Dafengji Village, Dacang Township, Weishan County, Yunnan Province, which was assigned into four groups, of no less than 3 000 m² in each group. In Group A, environmental cleaning was not conducted and 5% niclosamide ethanolamine salt granules were sprayed with drones at a dose of 40 g/m², and in Group B, environmental cleaning was performed, followed by 5% niclosamide ethanolamine salt granules sprayed with drones at a dose of 40 g/m², while in Group C, environmental cleaning was not conducted and 5% niclosamide ethanolamine salt granules were sprayed with knapsack sprayers at a dose of 40 g/m², and in Group D, environmental cleaning was performed, followed by 5% niclosamide ethanolamine salt granules sprayed with knapsack sprayers at a dose of 40 g/m². Then, each group was equally divided into six sections according to land area, with Section 1 for baseline surveys and sections 2 to 6 for snail surveys after chemical treatment. Snail surveys were conducted prior to chemical treatment and 1, 3, 5, 7 days post-treatment, and the mortality and corrected mortality of snails, density of living snails and costs of molluscicidal treatment were calculated in each group. RESULTS: The mortality and corrected mortality of snails were 69.49%, 69.09%, 53.57% and 83.48%, and 68.58%, 68.17%, 52.19% and 82.99% in groups A, B, C and D 14 days post-treatment, and the density of living snails reduced by 58.40%, 63.94%, 68.91% and 83.25% 14 days post-treatment relative to pre-treatment in four groups, respectively. The median concentrations of chemical molluscicides were 37.08, 35.42, 42.50 g/m² and 56.25 g/m² in groups A, B, C and D, and the gross costs of chemical treatment were 0.93, 1.50, 0.46 Yuan per m² and 1.03 Yuan per m² in groups A, B, C and D, respectively. CONCLUSIONS The molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones against O. hupensis snails is superior to manual chemical treatment without environmental cleaning, and chemical treatment with drones and manual chemical treatment show comparable molluscicidal effects following environmental cleaning in hilly regions. The cost of chemical treatment with drones is slightly higher than manual chemical treatment regardless of environmental cleaning. Spraying 5% niclosamide ethanolamine salt granules with drones is recommended in complex settings with difficulty in environmental cleaning to improve the molluscicidal activity and efficiency against O. hupensis snails.

OBJECTIVE: To investigate the efficacy and safety of intravesical instillation of heparin/alkalized lidocaine (lidocaine mixed with sodium bicarbonate) combined with hydrodistension and transurethral fulguration in the treatment of female interstitial cystitis (IC). METHODS: Female patients who attended the Department of Urology at the First Hospital of China Medical University between January 2012 and December 2020 and met the diagnostic criteria proposed in the guidelines of the American Urological Association with a new diagnosis of IC were selected for retrospective analysis. Cystoscopy and biopsy of suspicious lesions were performed at the time of diagnosis. All the patients were treated with an intravesical instillation regimen of 2% lidocaine 10 mL + 5% sodium bicarbonate 5 mL + heparin 25 000 IU for a continuous period of 12 months, with or without water dilatation and transurethral electrocautery according to the patient's preference, categorized as hydrodistension and transurethral fulguration (HD/TF) group and non-HD/TF group. The patients were evaluated before and 1, 6, and 12 months after treatment for O'Leary-Sant interstitial cystitis patient symptom index scores (ICSI), interstitial cystitis patient problem index scores (ICPI), visual analog scale (VAS) of suprapubic pain, and functional bladder capacity (FBC) changes. RESULTS: A total of 79 patients were collected in this study. Four (5.1%) of these patients underwent cystectomy due to pathological diagnosis of cancer or treatment failure. The remaining patients were followed up 1, 6 and 12 months after treatment. Repeated-measures ANOVA showed a significant decrease in ICPI, ICSI and VAS and an increase in FBC after treatment compared with before treatment (P < 0.05). FBC continued to decrease during the 1, 6 and 12 months' post-treatment follow-ups, with statistically significant differences; ICSI continued to decrease during the 1 and 6 months post-treatment follow-ups, with statistically significant differences, while the difference between ICSI at 6 months post-treatment and at 12 months' post-treatment was not statistically significant. In the HD/TF group, ICPI continued to decrease in the follow-up from 1 and 6 months after treatment, and the difference was statistically significant, while the difference between ICPI 6 months after treatment and 12 months after treatment was not statistically significant. There was no statistically significant difference between the remaining indicators 1, 6 and 12 months after treatment. ICPI, ICSI, VAS and FBC improved earlier and the changes in VAS and FBC were more significant in the HD/TF group compared with the non-HD/TF group (P < 0.05). CONCLUSION Heparin/alkalized lidocaine combination of intravesical instillation with hydrodistension and transurethral fulguration for IC is an effective treatment option. Heparin/alkalized lidocaine combination of intravesical instillation may be the first choice of treatment, which can significantly reduce the economic burden of patients and medical insurance system. If patients can accept it, transurethral fulguration with hydrodistension may be considered.

BACKGROUND: Nasal insertion is the preferred method for non-intubated patients in flexible bronchoscopy; however, the relatively narrow nasal cavity results in difficulties related to bronchoscope insertion. This study aimed to investigate whether pre-operative nasal probe tests could reduce the time to pass the glottis, improve the first-pass success rate and patients' tolerance, and reduce postoperative bleeding. METHODS: This three-arm prospective randomized controlled trial was conducted in a tertiary hospital between May and October 2020. Three hundred patients requiring diagnosis and treatment using flexible bronchoscopy were randomly allocated to three groups: control group, simple cotton bud detection group (CD group), and adrenaline + lidocaine detection group (AD group). The primary outcome was the time to pass the glottis. Secondary outcomes included the first-pass success rate, the patients' tolerance scores, and post-operative bleeding. One-way analysis of variance, Kruskal-Wallis H test, Chi-squared test, Fisher's exact test, and Bonferroni's multiple comparison tests were used in this study. RESULTS: In total, 189 men and 111 women were enrolled in this study, with a mean age of 55.72 ± 12.86 years. The insertion time was significantly shorter in the AD group than in the control group (18.00 s [12.00-26.50 s] vs . 24.00 s [14.50-45.50 s], P = 0.005). Both the AD (99% vs . 83%, χ2 = 15.62, P < 0.001) and CD groups (94% vs . 83%, χ2 = 5.94, P = 0.015) had a significantly higher first-pass success rate than the control group. Compared with the control group, post-operative bleeding (1% vs . 13%, χ2 = 11.06, P < 0.001) was significantly lower in the AD group. However, no significant difference was found in the patients' tolerance scores. CONCLUSIONS: Pre-operative nasal cavity probe tests especially with adrenaline and lidocaine during flexible bronchoscopy can significantly reduce the time to pass the glottis, improve the first-pass success rate, and reduce post-operative nasal bleeding. Pre-operative nasal probe tests are recommended as a time-saving procedure for patients undergoing flexible bronchoscopy.
