Arbutin is utilized in traditional remedies to cure numerous syndromes because of its anti-microbial, antioxidant, and anti-inflammatory properties. This study aimed to evaluate chemopreventive effects of arbutin on azoxymethane (AOM)-induced colon aberrant crypt foci (ACF) in rats. Five groups of rats were used: normal control group (rats injected hypodermically with sterile phosphate-buffered saline once per week for two weeks) and groups 2-5, which were subcutaneously inoculated with 15 mg/kg AOM once a week for two weeks. AOM control and 5-fluorouracil (5-FU) control groups were fed 10% Tween orally daily for 8 weeks using a feeding tube. The treated groups were fed 30 and 60 mg/kg arbutin every day for 2 months. ACF from the AOM control group had aberrant nuclei in addition to multilayered cells and an absence of goblet cells. The negative control group displayed spherical cells and nuclei in basal positions. Histological examination revealed a reduced number of AFC cells from colon tissues of the 5-FU reference group. Arbutin-fed animals showed down-regulation of proliferating cell nuclear antigen (PCNA) and up-regulation of Bax protein compared to AOM control. Rats fed with arbutin displayed a significant increase of superoxide dismutase (SOD) and catalase (CAT) activities in colon tissue homogenates compared to the AOM control group. In conclusion, arbutin showed therapeutic effects against colorectal cancer, explained by its ability to significantly decrease ACF, down-regulate PCNA protein, and up-regulate Bax protein. In addition, arbutin significantly increased SOD and CAT, and decreased malondialdehyde (MDA) levels, which might be due to its anti-proliferative and antioxidant properties.

Subdural Spread of Local Anesthetic Mimicking Cerebrovascular Accident: A Case Report of Horner's Syndrome, Upper Limb Paresthesia, and Motor Weakness After Thoracic Epidural Analgesia.
A 53-year-old woman underwent a thoracic epidural placement for a scheduled laparotomy. Postoperatively the patient had no appreciable epidural level after multiple epidural boluses and was noted to be severely hypotensive with right upper extremity weakness and numbness. She subsequently developed right-sided Horner's syndrome with worsening right upper extremity weakness and decreased sensation from C6 to T1. She regained full motor and sensory function in her right upper extremity with epidural removal. This unusual case raises awareness of the variability in the presentation of subdural spread and provides an example of an epidural complication that can mimic a cerebrovascular accident (CVA).

American Journal of Physical Medicine &... Jul 2024To evaluate the effectiveness of pulmonary rehabilitation (PR) programs and other rehabilitation interventions in adults with asthma.
OBJECTIVE
To evaluate the effectiveness of pulmonary rehabilitation (PR) programs and other rehabilitation interventions in adults with asthma.
DESIGN
Systematic review and meta-analysis.
RESULTS
MEDLINE (PubMed), EMBASE, Cumulative Index to Nursing & Allied Health Literature and CENTRAL were searched from inception to 31 May 2023. PROSPERO registration number: CRD42022331440. Thirty-six randomised controlled trials (RCTs) were analysed, and only 26 were pooled in the meta-analysis due to the heterogeneity of comparisons and outcomes across the studies. Pulmonary rehabilitation, compared with education associated with breathing exercises, may result in little to no difference in the Asthma Quality of Life Questionnaire (AQLQ) (mean difference 0.01 score, 95% confidence interval -0.48 to 0.50, 163 participants, three studies, low certainty).
CONCLUSION
Our findings show that pulmonary rehabilitation, compared with education associated with breathing exercises, may result in little to no difference in the impact of asthma on health-related quality of life. Overall, the certainty of evidence was low or very low preventing any firm conclusion on the effects of single or combined rehabilitation interventions.

British Journal of Clinical Pharmacology Jul 2024We explored whether esketamine anesthesia during hysteroscopic surgery can reduce intraoperative hemodynamic fluctuations and improve patient benefit.
AIMS
We explored whether esketamine anesthesia during hysteroscopic surgery can reduce intraoperative hemodynamic fluctuations and improve patient benefit.
METHODS
A total of 170 patients undergoing hysteroscopic surgery were enrolled, and 151 patients were finally included in the analysis, among which 19 used vasoactive drugs during surgery. Patients were randomly assigned to either the esketamine anesthesia group (E group) or the sufentanil anesthesia group (S group). The primary outcomes were blood pressure and heart rate during the surgery. Secondary outcomes included resistance to laryngeal mask insertion, demand for propofol and remifentanil, nausea and vomiting, Richmond Agitation and Sedation Scale (RASS), dizziness and pain intensity after resuscitation, vasoactive medication treatment, hospitalization time and expenses.
RESULTS
E group had a more stable heart rate, systolic blood pressure, diastolic blood pressure and mean blood pressure than the S group (p < 0.001). Patients in E group had a higher demand for propofol (p < 0.001) but better RASS scores (p < 0.001) after resuscitation. The incidence of intraoperative vasoactive medication use was higher in the S group (18.4% vs. 6.7%, p = 0.029). There were no statistically significant differences in terms of resistance to laryngeal mask insertion, remifentanil demand, time required for resuscitation, postoperative pain, dizziness, nausea or vomiting.
CONCLUSIONS
Compared with sufentanil, esketamine-induced anesthesia during hysteroscopic surgery can reduce intraoperative hemodynamic fluctuations and the incidence of intraoperative vasoactive medication. Although esketamine-induced anesthesia may increase the demand for propofol during surgery, it does not affect the anesthesia recovery time and the quality of patient recovery is better.

OBJECTIVES
Tympanostomy tube insertion (TTI) under local anesthesia (LA) is gaining popularity but literature comparing long-term outcomes for children undergoing TTI under LA versus general anesthesia (GA) is limited. This study compares the long-term quality of life (QoL) between LA and GA in children undergoing TTI. Secondary objectives included long-term behavioral changes, parental satisfaction, tube durability, and postoperative complications.
METHODS
We prospectively followed children aged under 6 who underwent TTI, under LA or GA, 2 years prior. We assessed QoL using validated scales (OM6, PedsQL), analyzed behavioral changes and parental satisfaction through qualitative scales, and retrieved data on tube durability and non-immediate complications.
RESULTS
A total of 84 children (LA = 42; GA = 42) had complete data and a minimum of 1 year of follow-up. Demographic data were similar, except for younger patients in the LA group (1.4 vs. 1.9 years, p = 0.02). LA group exhibited increased fear of health care professionals following TTI (LA: Likert scale 2.1/5, GA: 1.5/5, p = 0.04). Tube retention rate was shorter in the LA group (at 15 months: GA:72%, LA:50%, p = 0.039). Two years post-TTI, there were no differences regarding QoL (OM-6 score; LA: 15.2/100, GA: 21.4/100, p = 0.18, and PedsQL score; LA: 84.3/100, GA: 83.8/100, p = 0.90), parental satisfaction with anesthesia (GA: 4.5/5, LA: 4.6/5, p = 0.56), and postoperative complications (GA: 3/42, LA: 7/42, p = 0.18).
CONCLUSIONS
TTI under LA in children is associated with an increased fear of health care professionals and shorter functionality of tympanostomy tubes as compared to GA. No difference was observed in long-term QoL, parental satisfaction, and complications rate.

INTRODUCTION
Intraperitoneal instillation of local anaesthetic agents alone or in combination with opioids, α2 agonists such as Dexmedetomidine have been found to reduce postoperative pain following laparoscopic cholecystectomy. The study was designed to compare the better drug among Bupivacaine alone and Bupivacaine with Dexmedetomidine with respect to their analgesic efficacy and safety profile. in patients undergoing laparoscopic cholecystectomy.
PATIENTS AND METHODS
The study was carried out on sixty patients of the American Society of Anaesthesiologists (ASA) physical status I-II of either sex with ages ranging from 18 to 60 years posted for elective laparoscopic cholecystectomy under General Anaesthesia, equally divided into two groups, randomly allocated to one of the Groups using the table of randomization. Group B received Intraperitoneal Bupivacaine 40 ml 0.25% +5 ml normal saline and Group BD received Intraperitoneal Bupivacaine 40 ml 0.25% + Dexmedetomidine1 μg/kg diluted in 5 ml Normal saline.
RESULTS
The mean heart rate and blood pressure (systolic, diastolic and mean) readings were significantly lower in Group BD than in Group B. The mean duration of analgesia in our study was longer in Group BD (7.5 ± 0.73 hours) when compared to Group B (5.9 ± 0.55 hours) with p-value & 0.0001 and CI 1.27 to 1.9, which was statistically significant. However, the post-operative analgesic requirement (rescue/demand) in Group B was clinically earlier and statistically significant as compared to Group BD. Postoperative VAS score ≥3 was considered the benchmark for providing rescue analgesia in the form of injection of Diclofenac 75 mg IV. In our study, we observed the pain scores via VAS/NRS at 30 min, 1 h, 2 h, 4 h, 6 h, 8 h, 10 h, 12 h, 14 h, 16 h, 18 h, 20 h, 22 h and 24 h postoperatively. A comparison of pain scores from 30 min to 10hrs postoperatively showed a significant difference in both Groups with Group B having significantly higher VAS scores and lower VAS scores with Group BD.
CONCLUSIONS
Our study suggests that there is a shorter duration of action of 0.25% Bupivacaine alone as compared to 0.25% Bupivacaine + Dexmedetomidine. Since the laparoscope is still inside the abdominal cavity the drugs are easy to administer with no adverse effects and with a good safety profile because of the visualization of drug deposition in the right place. Intraperitoneal instillation of Bupivacaine with Dexmedetomidine for postoperative analgesia was very promising as a part of multimodal analgesia in laparoscopic cholecystectomy.

Burn injury contributes to significant morbidity and mortality in the United States. Despite an increased focus on racial and ethnic disparities in healthcare, there remains a critical knowledge gap in our understanding of the effect of these disparities on complications experienced by burn patients. The American Burn Association's National Burn Repository data were reviewed from 2010-2018. Information regarding demographics, burn mechanism and severity, complications, and clinical outcomes were recorded. Data analysis was performed using 1:1 propensity-score-matching and logistic regression modeling. A separate analysis of Hispanic and non-Hispanic patients was performed using Chi squared tests. Among 215,071 patients, racial distribution was 65.16% white, 19.13% black, 2.18% Asian, 0.74% American Indian/Alaskan Native, and 12.78% other. Flame injuries were the most common cause (35.2%), followed by scald burns (23.3%). All comparisons were made in reference to the white population. Black patients were more likely to die (OR: 1.28; 95%CI: 1.17-1.40), experience all (OR: 1.08; 95%CI: 1.03-1.14), cardiovascular (OR: 1.24; 95%CI: 1.08-1.43), or infectious (OR: 1.64; 95%CI: 1.40-1.91) complications, and less likely to experience airway complications (OR: 0.83; 95%CI: 0.74-0.94). American Indian/Alaskan Native patients were more likely to experience any complication (OR: 1.33; 95%CI: 1.05-1.70). All minority groups had increased length of hospital stay. Black, Asian, and other patients had longer length of ICU stay. Black patients had longer ventilator duration. Among 82,775 patients, 24,075 patients were identified as Hispanic and 58,700 as non-Hispanic. Statistically significant differences were noted between groups in age, TBSA, proportion of 2nd degree burn, and proportion of 3rd degree burn (p<0.01). These findings highlight the need for further work to determine the etiology of these disparities to improve burn care for all patients.

Journal of the Indian Society of... Apr 2024Pharmacological methods, specifically sedatives, have gained popularity in managing the behavior of children during dental appointments. (Randomized Controlled Trial)
Randomized Controlled Trial Comparative Study
Comparative evaluation of intranasal dexmedetomidine, intranasal midazolam, and nitrous oxide for conscious sedation of anxious children undergoing dental treatment: A randomized cross-over trial.
BACKGROUND
Pharmacological methods, specifically sedatives, have gained popularity in managing the behavior of children during dental appointments.
AIM
The aim of this study was to compare 1 m/kg intranasal dexmedetomidine, 0.3 mg/kg intranasal midazolam, and nitrous oxide in evaluating the level of sedation, behavior of the child, onset of sedation, physiologic signs, and adverse effects.
MATERIALS AND METHODS
In this cross-over trial, 15 children aged 6-8 years were randomized to receive intranasal atomized dexmedetomidine, intranasal atomized midazolam, and inhalation nitrous oxide at three separate visits. After administering the sedative agent, a single pulpectomy was performed during each appointment, and the outcomes were recorded. The washout period between each visit was 1 week.
RESULTS
All three sedative agents were equally effective in controlling overall behavior. Dexmedetomidine showed lower sedation level scores (agitated; score 9) than the other groups. There was a statistically significant difference in the onset of sedation, with dexmedetomidine having the longest onset of 36.2 ± 9.47 min. Coughing and sneezing were predominantly observed after administration of intranasal midazolam. Oxygen saturation levels were statistically lower in the intranasal midazolam group during local anesthesia administration and post-treatment.
CONCLUSION
0.3 mg/kg intranasal midazolam is as effective as nitrous oxide sedation for controlling behavior and providing adequate sedation in pediatric dental patients. However, 1 m/kg dexmedetomidine did not provide the same level of sedation and had a significantly longer onset. 0.3 mg/kg intranasal midazolam is an effective alternative to nitrous oxide sedation in anxious children.

Randomized Controlled Trial
CONTEXT
For successfully managing pediatric dental patients, local anesthesia is essential to eliminate pain during or after the operative period. An early recovery from soft-tissue anesthesia after an inferior alveolar nerve block (IANB) should benefit a young child patient by avoiding the risk of inadvertently biting the soft tissues.
AIMS
Hence, the purpose of the study was to (1) evaluate and compare the efficacy of pre- and postoperative ibuprofen on pain perception in children who undergo IANB anesthesia with or without the use of PM and (2) evaluate the average time required for reversal of anesthesia symptoms using phentolamine mesylate.
METHODS
The present study was a randomized, clinical trial performed among 60 children between 6 and 8 years of age using a convenient sampling method. The children were randomly assigned into four equal groups of 15 each using the computer-generated randomization sequence. IANB anesthesia was performed using 2% lignocaine with 1:100,000 epinephrine, and a mandibular primary molar pulpotomy was performed on each group. Group 1: the ibuprofen tablet was taken 1 h before the onset of the procedure. Group 2: ibuprofen tablet 30 min after the pulpotomy procedure. Group 3: the ibuprofen tablet was taken 1 h before the onset of the procedure, and the Phentolamine mesylate (PM) injection was administered. Group 4: immediately after the pulpotomy, the PM injection was administered, and an ibuprofen tablet was taken 30 min after the pulpotomy procedure. All children were assessed for the duration of soft-tissue anesthesia, their behavior scores and pain rating, as well as the incidence of postoperative self-inflicted injuries.
STATISTICAL ANALYSIS USED
A one-way ANOVA was used to compare the average time needed for the reversal of anesthetic symptoms between groups. The effects of phentolamine, local anesthetics, and ibuprofen on the child's behavior and pain scores were compared using the Student's t-test. For the study, P < 0.05 was accepted as statistically significant.
RESULTS
The time needed for the full reversal of anesthetic symptoms to manifest on the tongue and lip was substantially reduced by the injection of phentolamine (P < 0.001). The use of phentolamine for reversal or the intake of ibuprofen pre- or postoperatively did not exhibit any significant variation in the behavior, pain experience, or incidence of self-inflicted injuries in the child.
CONCLUSION
It is evident that although phentolamine injections shorten the duration of anesthesia, the adjunctive use of pre- or postoperative ibuprofen did not significantly alter pain scores.
