Ultrasound-Guided External Oblique Intercostal Plane Block for Postoperative Analgesia in Laparoscopic Sleeve Gastrectomy: A Prospective, Randomized, Controlled, Patient and Observer-Blinded Study.

PURPOSE: The external oblique intercostal plane (EOI) block is a novel block technique for anterolateral upper abdominal wall analgesia. The superficial nature of the external oblique intercostal plane allows it to be easily identified even in patients with obesity. The aim of this study was to test the hypothesis that EOI block would reduce IV morphine consumption within 24 h after laparoscopic sleeve gastrectomy. MATERIALS AND METHODS: Patients were randomly assigned to one of two groups: EOI block group and control group. The patients in the EOI block group received ultrasound-guided bilateral EOI block with a total of 40 ml 0.25% bupivacaine after anesthesia induction. The patients in the control group received no intervention. Postoperatively, all the patients were connected to an intravenous patient controlled analgesia (PCA) device containing morphine. The primary outcome of the study was IV morphine consumption in the first postoperative 24 h. RESULTS: The median [interquartile range] morphine consumption at 24 h postoperatively was significantly lower in the EOI block group than in the control group (7.5 [3.5 to 8.5] mg vs 14 [12 to 20] mg, p = 0.0001, respectively). Numerical rating scale (NRS) scores at rest and during movement were lower in the EOI block group than in the control group at 2, 6, and 12 h but were similar at 24 h. No block-related complications were observed in any patients. CONCLUSION: The results of the current study demonstrated that bilateral EOI block reduced postoperative opioid consumption and postoperative pain in patients with obesity undergoing laparoscopic sleeve gastrectomy.

The evaluation of effective rate and pain intensity of root canal treatment in primary teeth-a retrospective study.

Two-visit root canal treatment for children reduce the time of visits and the by-chair time in comparison with the three-visit root canal treatment. However, it is not clear whether two-visit root canal treatment increase the risk of complications. This study aimed to evaluate the clinical effects and post-operative pain intensity after the root canal treatment between two-visit and three-visit groups in primary molars from children.106 patients were screened for eligibility, of which 74 went back to the preservation visit. Therefore, 74 primary molars from 74 children that diagnosed with chronic pulp and periodontal tissue diseases in the clinics of pediatric dentistry were retrospectively analyzed, in which 37 in the two-visit group and 37 in the three-visit group. The total effective rate and postoperative pain intensity were assessed after treatment and all statistical data were carried out with SPSS software.The average age of children in the two-visit and three-visit groups was 6.4 and 7.0, respectively, with no significant difference (p = 0.056). The two-visit group consisted of 59.5% male and 40.5% female children, while the three-visit group consisted of 56.8% male children and 43.2% female children (p = 0.813). Two months after treatment, the total effective rate in the three-visit group was 97.30%, a little higher than that in the two-visit group (94.59%), but with no significant difference (p = 0.201). Besides, there was also no significant difference in pain intensity between the two-visit and three-visit groups (p = 0.692). Therefore, there were no significant difference of total effective rate and pain intensity in root canal treatment between the two-visit and three-visit groups in primary molars from children.

Trigeminal neuralgia and trigeminal neuropathic pain.

It is very important that the dental team are aware of the varied presentations of pain in the mouth, face and other parts of the trigeminal region which are not directly caused by teeth or oral structures. Our understanding of underlying causes in this complex area is evolving. Ultimately, patients who present with what may at first seem to be oral or dental problems will require specialist input in secondary care with potential for use of systemic medications. This article reviews the common non-dental pains encountered in the orofacial region related to dysfunction of the trigeminal nerve.

4. Painful diabetic polyneuropathy.

INTRODUCTION: Pain as a symptom of diabetic polyneuropathy (DPN) significantly lowers quality of life, increases mortality and is the main reason for patients with diabetes to seek medical attention. The number of people suffering from painful diabetic polyneuropathy (PDPN) has increased significantly over the past decades. METHODS: The literature on the diagnosis and treatment of diabetic polyneuropathy was retrieved and summarized. RESULTS: The etiology of PDPN is complex, with primary damage to peripheral nociceptors and altered spinal and supra-spinal modulation. To achieve better patient outcomes, the mode of diagnosis and treatment of PDPN evolves toward more precise pain-phenotyping and genotyping based on patient-specific characteristics, new diagnostic tools, and prior response to pharmacological treatments. According to the Toronto Diabetic Neuropathy Expert Group, a presumptive diagnosis of "probable PDPN" is sufficient to initiate treatment. Proper control of plasma glucose levels, and prevention of risk factors are essential in the treatment of PDPN. Mechanism-based pharmacological treatment should be initiated as early as possible. If symptomatic pharmacologic treatment fails, spinal cord stimulation (SCS) should be considered. In isolated cases, where symptomatic pharmacologic treatment and SCS are unsuccessful or cannot be used, sympathetic lumbar chain neurolysis and/or radiofrequency ablation (SLCN/SLCRF), dorsal root ganglion stimulation (DRGs) or posterior tibial nerve stimulation (PTNS) may be considered. However, it is recommended that these treatments be applied only in a study setting in a center of expertise. CONCLUSIONS: The diagnosis of PDPN evolves toward pheno-and genotyping and treatment should be mechanism-based.

The curative effect of fire needling combined with filiform needling on tension-type headache and its effect on the tenderness of pericranial muscles. / ç«é’ˆè”åˆæ¯«é’ˆæ²»ç–—ç´§å¼ æ€§å¤´ç—›çš„ç–—æ•ˆåŠå¯¹é¢ å‘¨è‚Œè‚‰åŽ‹ç—›çš„å½±å“.

OBJECTIVES: To observe the curative effect of fire needling pricking pericranial tender points combined with filiform needling on tension-type headache (TTH) and its effect on pericranial muscle tenderness, and explore the correlation between changes of headache symptoms and pericranial muscle tenderness in TTH, to analyze the influence of pericranial muscle tenderness on TTH. METHODS: A total of 41 TTH patients in the treatment group and 38 TTH patients in the control group completed the study. The patients in the treatment group were treated with fire needling at pericranial tender points combined with filiform needling at Baihui (GV20), Sishencong (EX-HN1), Shenting (GV24), Touwei (ST8) and Fengchi (GB20). The patients in the control group were only treated with the same filiform needling as the treatment group. Patients in the two groups were treated twice a week for 8 weeks. Before and after treatment, the days of headache onset, the number and distribution of pericranial muscle tender points were recorded, the degree of headache was evaluated by visual analogue scale and the threshold of pericranial muscle tender points were measured. The correlations between the changes of the days and degree of headache onset and the changes of the number and threshold of pericranial muscle tender points were analyzed. The effective rates in the two groups were calculated. RESULTS: Compared with those before treatment, the days of headache onset and the degree of headache were decreased (P<0.05) in the two groups；the number of pericranial muscle tender points was decreased (P<0.05) and the tenderness threshold was increased (P<0.05) in the treatment group. After treatment, compared with the control group, the days of headache onset, the degree of headache, and the number of pericranial muscle tender points were decreased (P<0.05), and the tenderness threshold was increased (P<0.05) in the treatment group. The decrease of the days and degree of headache was positively correlated with the decrease of number and the increase of tenderness threshold of pericranial muscle tender points (P<0.05). The effective rate in the treatment group was 87.80% (36/41), which was higher than 57.89% (22/38) in the control group (P<0.05). The most common anatomic location of tender points in baseline was superior trapezius muscle, followed by sternocleidomastoid muscle, superior nuchal line, temporal muscle, masseter muscle, etc. CONCLUSIONS: The fire needling at the pericranial muscle tender points combined with filiform needling on TTH patients can significantly improve the clinical symptoms and reduce the pericranial muscle tenderness. The pericranial muscle tenderness is an important factor in the pathogenesis of TTH.

Low Patient Weight and Long Intubation Time Are Key Factors for Pain during Colonoscopy.

Although the clinical usefulness of colonoscopy has been established, the procedure remains painful for many patients. This study was designed to clarify the factors predicting colonoscopy-related pain. We evaluated 283 consecutive patients who completed a first-ever, total colonoscopy without sedatives or analgesics. The severity of pain symptoms was evaluated by a numeric rating scale (NRS) in a questionnaire immediately after the colonoscopy. Patient backgrounds and endoscopic findings were analyzed to evaluate their association with pain. Out of 283 patients, 53 scored their pain 0-1 on the NRS while 48 scored it 6-10. We defined the colonoscopies of the former and latter patients as painless and painful, respectively, and compared the two. Multivariate analyses revealed that low body weight (OR 4.95, 95%CI 1.89-12.99) and longer intubation time (OR 3.63, 95%CI 1.46-9.03) were significant risk factors for painful colonoscopy. To identify factors contributing to the increased intubation time, we divided subjects into short- and long-intubation-time groups based on a median insertion time of 7 min. Older age (OR 2.28, 95%CI 1.31-3.98), previous abdominal surgery (OR 1.93, 95%CI 1.13-3.32) and findings of invasive cancer (OR 10.90, 95%CI 1.34-88.90) were significant factors for longer intubation time.

The effectiveness of mobilization with movement on patients with mild and moderate carpal tunnel syndrome: A single-blinded, randomized controlled study.

STUDY DESIGN: Single-blinded, randomized controlled study. INTRODUCTION: Carpal Tunnel Syndrome (CTS) causes pain and loss of function in the affected hand. The mobilization with movement (MWM) technique is a manual therapy method applied to correct joint movement limitation and to relieve pain and functional disorders. PURPOSE OF THE STUDY: This study aimed to examine the effectiveness of MWM technique on pain, grip strength, range of motion, edema, hand reaction, nerve conduction, and functional status in patients with CTS. METHODS: A total of 45 patients enrolled in the study. The MWM group (n = 18) completed a 4-week combined conservative physiotherapy and MWM program, whereas the control group (n = 18) received only the 4 weeks of conservative physiotherapy. Pain severity according to the numerical rating scale was used as primary outcome. RESULTS: We found an improvement within the subjects in resting pain (MWMG:5.1 ± 3.6 vs 1.1 ± 2.4, Effect Size (ES)=1.3; CG:4.5 ± 3.3 vs 1.0 ± 2.2, ES=1.1), in activity pain (MWMG:6.5 ± 3.7 vs 1.1 ± 2.4, ES=1.5; CG:4.8 ± 3.4 vs 2.2 ± 2.3, ES=1) and in night pain (MWMG:5.9 ± 3.2 vs 1.8 ± 2.5, ES=1.2; CG:5.3 ± 4.2 vs ± 2.3 ± 3.5, ES=0.9). For between the groups, a statistical difference was found for the activity pain, Disabilities of the Arm Shoulder and Hand Questionnaire score (MWMG:52.2 ± 23.8 vs 27 ± 24.7, ES=1.3; CG:47.0 ± 24.8 vs 41.5 ± 22.1, ES=0.2), Michigan Hand Outcomes Questionnaire (MHQ-1), (MWMG:44.4 ± 23.7 vs 74.7 ± 24.5, ES=1.3; CG:44.8 ± 17.4 vs 57.4 ± 21.7, ES=0.9) and MHQ-5 (MWMG:68.8 ± 13.1 vs 82.5 ± 11.5, ES=0.9; CG:63.4 ± 26.7 vs 59.3 ± 25.8, ES=0.1) parameters in favour of MWM group. DISCUSSION: This study showed that MWM compared to conservative physiotherapy might be more effective in reducing perceived symptoms in mild and moderate CTS patients. CONCLUSIONS: MWM produced a small benefit to recovery of activity pain and upper extremity functionality level outcomes of patients with mild to moderate CTS when added to a traditional CTS physical therapy program.

Somatosensory profiling of patients undergoing alcohol withdrawal: Do neuropathic pain and sensory loss represent a problem?

INTRODUCTION: Chronic heavy alcohol use is known to cause neurological complications such as peripheral neuropathy. Concerning the pathophysiology, few sural nerve and skin biopsy studies showed that small fibers might be selectively vulnerable to degeneration in alcohol-related peripheral neuropathy. Pain has rarely been properly evaluated in this pathology. The present study aims at assessing pain intensity, potential neuropathic characteristics as well as the functionality of both small and large nerve sensitive fibers. METHODS: In this observational study, 27 consecutive adult patients, hospitalized for alcohol withdrawal and 13 healthy controls were recruited. All the participants underwent a quantitative sensory testing (QST) according to the standardized protocol of the German Research Network Neuropathic Pain, a neurological examination and filled standardized questionnaires assessing alcohol consumption and dependence as well as pain characteristics and psychological comorbidities. RESULTS: Nearly half of the patients (13/27) reported pain. Yet, pain intensity was weak, leading to a low interference with daily life, and its characteristics did not support a neuropathic component. A functional impairment of small nerve fibers was frequently described, with thermal hypoesthesia observed in 52% of patients. Patients with a higher alcohol consumption over the last 2 years showed a greater impairment of small fiber function. DISCUSSION: Patients report pain but it is however unlikely to be caused by peripheral neuropathy given the non-length-dependent distribution and the absence of neuropathic pain features. Chronic pain in AUD deserves to be better evaluated and managed as it represents an opportunity to improve long-term clinical outcomes, potentially participating to relapse prevention.

Consistency between the 2016 ACR criteria and a previous diagnosis or hypothesis of fibromyalgia in a specialised referral clinic.

OBJECTIVES: Fibromyalgia (FM) is a complex syndrome whose hallmark features are chronic widespread pain, sleep disturbances, fatigue and cognitive dysfunctions. However, it is still difficult to apply validated diagnostic criteria. The aim of this study is to examine the accuracy of a previous diagnosis/diagnostic hypothesis of FM according to the 2016 ACR diagnostic criteria. METHODS: All of the patients newly referred to a private rheumatological clinic with the specific request for a consultation because if FM over an 18-month period were evaluated by means of a standardised protocol in order to determine whether they fulfilled the 2016 ACR diagnostic criteria for FM. They were initially divided into three groups: those with a previous diagnosis of FM (group 1), those with a physician's diagnostic hypothesis of FM (group 2) and those who personally hypothesised FM (group 3). They were subsequently classified as having FM, IFM (borderline scores) or not having FM (non-FM) on the basis of the 2016 ACR diagnostic criteria. RESULTS: The study involved 216 patients (25 males and 191 females): 112 in group 1, 49 in group 2, and 55 in group 3. Only 89 patients (41.2%) fulfilled the ACR criteria; 42 (19.44%) met the study protocol-defined scores for IFM; and 85 (39.35%) were diagnosed as not having FM. Only 50% of the patients with a previous diagnosis of FM fulfilled the ACR criteria, and just under 25% did not have FM. Almost 50% of the patients with a physician's diagnostic hypotheses of FM did not have FM, whereas 20% of the patients who personally hypothesised FM fulfilled the ACR criteria. GP scores and TPCs were significantly different (FM > IFM, FM > non-FM, and IFM > non-FM) as were WPI, SSS and PSD scores for FM > IFM group. Rheumatologists made the previous diagnosis in 92.85% of patients, 53.84% of whom met the ACR criteria and about 20% did not have FM; and as many as 37.5% of the patients with a previous diagnosis made by a non-rheumatologist did not have FM. The non-FM patients were given 84 alternative diagnoses, 78.5% of which referred to rheumatic diseases. One hundred and thirty-one patients had 86 closely pain-related co-morbidities, 94.1% of which were rheumatic diseases. CONCLUSIONS: Our findings confirm the inaccuracy of FM diagnoses and highlights the possibility that in everyday clinical practice, they are not always made with reference to very specific criteria and that there is a high risk of classifying non-FM patients as having FM. They also underline the importance of an accurate differential diagnosis. Separately classifying as IFM those patients who do not meet the ACR criteria, but have clinical findings indicating FM, may help to prevent their exclusion from specific treatment(s).

Pain assessment following open hemorrhoidectomy under local anesthesia versus saddle block: a multicenter randomized controlled trial.

BACKGROUND: There is disparity in evidence on pain assessment post open hemorrhoidectomy (OH) using local anesthesia and its use in developing countries compared to developed countries. Therefore, we conducted this study to assess the occurrence of postoperative pain following open hemorrhoidectomy under local anesthesia versus saddle block for uncomplicated 3rd or 4th degree hemorrhoids. METHODS: This was a prospective equivalence randomized, double blind controlled trial conducted from December 2021 to May 2022 among patients with primary uncomplicated 3rd or 4th degree hemorrhoids. Pain severity was assessed at 2, 4 and 6 h post open hemorrhoidectomy using visual analogue scale (VAS). Data was analysed using SPSS version 26 at a p < 0.05 as statically significant using visual analogue scale (VAS). RESULTS: We recruited 58 participants in this study who underwent open hemorrhoidectomy under local anesthesia or saddle block (29 participants per group). The sex ratio was of 1.15 of female to male and a mean age of 39 ± 13. VAS was found to be different at 2 h post OH compare to other time of pain assessment but not statically significant by area under the cover (AUC) (95% CI = 486-0.773: AUC = 0.63; p = 0.09) with a none significance by Kruskal-Wallis's test (p:0.925). CONCLUSION: Local anesthesia was found to be having a similar pain severity occurrence in post operative period among patients undergoing open hemorrhoidectomy for primary uncomplicated 3rd or 4th degree hemorrhoids. Close monitoring of pain in postoperative period is mandatory especially at 2 h to assess need of analgesia. TRIAL REGISTRATION: Pan African Clinical Trials Registry, PACTR202110667430356.

Focused Chest Pain Assessment for Early Detection of Acute Coronary Syndrome: Development of a Cardiovascular Digital Health Intervention.

Background: Chest pain misinterpretation is the leading cause of pre-hospital delay in acute coronary syndrome (ACS). This study aims to identify and differentiate the chest pain characteristics associated with ACS. Methods: A total of 164 patients with a primary complaint of chest pain in the ER were included in the study. ACS diagnosis was made by a cardiologist based on the WHO criteria, and the patients were interviewed 48 hours after their admission. Furthermore, every question was analysed using the crosstabs method to obtain the odds ratio, and logistic regression analysis was applied to identify the model of focused questions on chest pain assessment. Results: Among the samples, 50% of them had an ACS. Four questions fitted the final model of ACS chest pain focused questions: 1) Did the chest pain occur at the left/middle chest? 2) Did the chest pain radiate to the back? 3) Was the chest pain provoked by activity and relieved by rest? 4) Was the chest pain provoked by food ingestion, positional changes, or breathing? This model has 92.7% sensitivity, 84.1% specificity, 85% positive predictive value (PPV), 86% negative predictive value (NPV), and 86% accuracy. After adjusting for gender and diabetes mellitus (DM), the final model has a significant increase in Nagelkerke R-square to 0.737 and Hosmer and Lemeshow test statistic of 0.639. Conclusion: Focused questions on 1) left/middle chest pain, 2) retrosternal chest pain, 3) exertional chest pain that is relieved by rest, and 4) chest pain from food ingestion, positional changes, or breathing triggering can be used to rule out ACS with high predictive value. The findings from this study can be used in health promotion materials and campaigns to improve public awareness regarding ACS symptoms. Additionally, digital health interventions to triage patients' suffering with chest pain can also be developed.

Diagnosis, management and impact of painful diabetic peripheral neuropathy: A patient survey in four European countries.

AIMS: The aim of this study was to assess patient perspectives and experiences of the impact of neuropathic pain, painful diabetic neuropathy (pDPN) diagnosis and treatment, and the patient-healthcare professional (HCP) relationship. METHODS: We conducted a quantitative online survey in Germany, the Netherlands, Spain, and the UK among adults with diabetes who responded "yes" to at least four of ten questions of in the Douleur Neuropathique en 4 Questions (DN4) questionnaire. RESULTS: Of 3626 respondents, 576 met the eligibility criteria. Daily pain was rated as moderate or severe by 79 % of respondents. Most participants reported a negative impact of their pain on sleep (74 %), mood (71 %), exercise (69 %), concentration (64 %) and daily activities (62 %), and 75 % of those in employment had missed work because of their pain in the past year. Overall, 22 % of respondents avoided discussing pain with their HCP, 50 % had not received formal pDPN diagnosis, and 56 % had not used prescribed pain medications. Although two-thirds (67 %) of respondents reported feeling satisfied or very satisfied with treatment, 82 % of these patients still experienced daily moderate or severe pain. CONCLUSIONS: Neuropathic pain in people with diabetes affects daily life and remains underdiagnosed and undertreated in clinical practice.

Effects of Dexmedetomidine on Postoperative Pain and Recovery Time in Obese Patients.

Objective: The objective of this study is to investigate the effect of dexmedetomidine on postoperative pain and recovery time in obese patients. Methods: A total of 100 obese patients with body mass index (BMI) ≥ 30 kg/m2 who underwent laparoscopic sleeve gastrectomy under general anesthesia in our hospital from January 2019 to December 2021 were included and assigned into DEX group (dexmedetomidine group) and NS group (normal saline group). The bariatric surgery patients who were given normal saline pump were the NS group (n = 50), and the bariatric surgery patients who were given the dexmedetomidine pump were the DEX group (n = 50). The patients in the DEX group were given continuous intravenous infusion of dexmedetomidine before, during, and after induction of anesthesia at a dose of 0.4 µg. kg-1. h-1, 0.4 µg·kg-1. h-1, 0.2 µg·kg-1. h-1, respectively. The NS group was infused with the same volume of normal saline for the same time. The two groups of patients were treated with the same anesthesia induction and maintenance program. By comparing the operation, anesthesia, postoperative extubation, and recovery time of the two groups of patients, the effect of dexmedetomidine on the postoperative recovery time of obese patients was analyzed. Visual analogue scale (VAS) and adverse reactions were compared to analyze the effect of dexmedetomidine on postoperative pain in obese patients. Results: The operation, anesthesia, postoperative extubation, and recovery time of the DEX group were significantly lower than those of the NS group, whereas the VAS and adverse reactions were significantly lower than those in the NS group (P < 0.05). Conclusion: An appropriate dose of dexmedetomidine in bariatric surgery for morbidly obese patients can effectively shorten the recovery time and extubation time of patients, reduce postoperative pain and the incidence of adverse reactions, and is worthy of clinical application. Dexmedetomidine 2 µg/kg has promising anesthesia benefits in bariatric surgery of obese patients, can provide favorable analgesia and quality of recovery, help reduce the degree of stress response of patients, and does not increase the risk of adverse events. However, this study has certain limitations, so physicians should tailor the dosage according to the patient's physical condition in clinical practice.

[Characteristics and treatment of pain in Parkinson's disease].

Pain is a representative non-motor symptom in patients with Parkinson's disease (PD). Pain is one of the most common symptoms that plague patients with PD regardless of the stage of the disease, also it can exacerbate other symptoms, such as depression, anxiety or sleep disturbance, and lead to impaired quality of life. However, pain is often not adequately evaluated and treated. PD patients complain of a wide variety of pain, including both PD-related pain which caused by PD-specific symptoms, for example, rigidity, bradykinesia or motor fluctuation, and PD-unrelated pain, and it can be divided into central and peripheral depending on the site of the disorder. In the medical care of the pain, it is important to evaluate the type and severity of the pain using PD-specific assessment scales such as King's PD pain scale and to consider the evidence-based treatment methods according to the pathophysiology of the pain.

Quantifying the intensity of adverse events with ibuprofen and oxycodone: an observational cohort study.

OBJECTIVE: To quantify the frequency and intensity of adverse events (AEs), commonly known as side effects, experienced by children receiving either ibuprofen or oxycodone for pain management following an acute fracture. Secondary objectives were to quantify functional outcome impairment and describe demographic and clinical characteristics associated with AEs. DESIGN: Observational cohort study. SETTING: Paediatric emergency department. PATIENTS: Patients (n=240) aged 4-16 years diagnosed with an acute fracture. INTERVENTION: Prescribed either ibuprofen (n=179) or oxycodone (n=61) for pain. MAIN OUTCOME MEASURES: Families were called for the first 3 days after discharge to report the presence and intensity of AEs and their child's functional outcomes (ability to eat, sleep, play or attend school). RESULTS: On day 1, children using oxycodone were more likely to report any AE (χ2 1=13.5, p<0.001), nausea (χ2 1=17.0, p<0.001), vomiting (χ2 1=11.2, p<0.001), drowsiness (χ2 1=13.7,p<0.001), constipation (χ2 1=8.9, p=0.003) and dizziness (χ2 1=19.1, p<0.001), compared with those using ibuprofen. Children receiving oxycodone reported greater severity of abdominal pain (oxycodone: mean 5.4 SD 3.1; ibuprofen mean 2.5 SD 1.4, F1 13=6.5, p=0.02) on day 1 and worse intensity of constipation (oxycodone: mean 4.9 SD 2.1; ibuprofen mean 3.2 SD 2.2, F1 33=4.5, p=0.04) over all 3 days. Use of oxycodone was associated with an increased odds of experiencing an AE on day 1 (OR=1.31 (95% CI 1.13 to 1.52)). Higher pain scores (OR=1.50 (95% CI 1.12 to 2.01)), lower extremity fracture (OR=1.25 (95% CI 1.07 to 1.47)) and undergoing ED sedation (OR=1.16 (95% CI 1.01 to 1.34)) were associated with missing school. Higher pain scores (OR=1.50 (95% CI 1.14 to 1.97)) and lower extremity fractures (OR=1.23 (95% CI 1.07 to 1.43)) were also associated with less play. CONCLUSIONS: Oxycodone is associated with more frequent AEs overall, higher intensity gastrointestinal AEs and greater functional limitations compared with ibuprofen. Lower extremity fractures cause more functional limitations than upper extremity fractures. Clinicians should consider these differences when providing fracture pain care for children.

Quadratus Lumborum Block with Laparoscopic Assisted Catheter Placement Technique in Donor Nephrectomy: A Preliminary Report.

Quadratus lumborum block (QLB) is a new fascial plane block that may be helpful for laparoscopic surgeries. In this present study, we aim to evaluate the analgesic efficacy of QLB in laparoscopic living related donor nephrectomy (LLRDN) applied continuously via a catheter that was placed under laparoscopic vision by the surgeon. Following the approval of the Clinical Research Ethics Committee of Istanbul University, Istanbul Medical Faculty (2019/1552), 9 study (Group QLB) and 26 control (Group M) patients that underwent LLRDN were enrolled in this retrospective study. All donors underwent left nephrectomy via transperitoneal laparoscopic approach. An epidural catheter was placed between the QL and psoas major (PM) fascial plane intraoperatively by the surgeon under laparoscopic direct vision, and bupivacaine 0.25% 20 mL was injected through the catheter. After the operation, for group QLB, we used a continuous infusion of bupivacaine 0.1% 7 mL/h over 24 hours. Group M patients received intravenous morphine patient controlled analgesia for 24 hours, postoperatively. Pain scores, total morphine consumption, and complications during the first 24 hours after surgery were recorded. During the first postoperative 24 hours, morphine requirement decreased by more than 70% in Group QLB (Group QLB: 5.11 ± 1.16 mg vs Group M: 16.8 ± 7.1 mg) (P < .0001). Postoperative Numeric Rating Scale (NRS) values at the 45th minute and first hour were both significantly lower in Group QLB than Group M (P < .01). This preliminary report showed that QL catheter placement technique provides good postoperative analgesia in patients undergoing LLRDN. However, further randomized controlled studies with extended patient numbers are required to test the efficacy of the technic.

Addition of magnesium sulfate to bupivacaine improves analgesic efficacy after tonsillectomy: A randomized trial and a CONSORT analysis.

OBJECTIVES: The main objective of this study was to compare the wound infiltration (peritonsillar fossa) of magnesium sulphate combined with bupivacaine, bupivacaine alone and saline solution on post-tonsillectomy pain in children. The accessory objectives were to evaluate the effect of magnesium sulphate infiltration on prevention of laryngospasm and occurrence of nausea/vomiting. METHODS: This study is a prospective; double blinded and randomized clinical trial. Seventy-five children undergoing tonsillectomy were enrolled. Patients were randomized into three groups using closed envelop technique. Group 1 (N=24) received saline solution (NaCl), group 2 (N=25) received 0.25% bupivacaine (1mg/kg) and group 3 received magnesium sulphate (5mg/kg) and 0.25% bupivacaine (1mg/kg) after tonsillectomy using three-point technique. Pain was evaluated using mCHEOPS scale. The occurrence of laryngospasm, nausea and vomiting was monitored. RESULTS: The mCHEOPS scores of the group 3 were significantly lower than those of the group 2 and 1 (P<0.001). Time to first analgesic administration was longer for the group 3 than for the groups 2 and 1 (P<0.001). The mean consumption of additional analgesic drugs was lower for the group 3 than the other groups (P<0.001). There were no episodes of laryngospasm in the group 3 in comparison with the other groups. The difference of the incidence of nausea and vomiting was not statistically significant (P=0.628). CONCLUSION: The adjunction of magnesium sulphate to bupivacaine proved to provide more efficient pain control than bupivacaine alone. However, the small number of participants and the absence of sampling at the P level of 0.005 do not allow to conclude with absolute certainty.

[A prospective randomized controlled study of the difference between BPPV manual reduction and automatic device reduction].

Objective:To investigate the difference between manual reduction and automatic device reduction in the treatment of benign paroxysmal positional vertigo（BPPV）, and to provide evidence-based medicine for the clinical choice of BPPV treatment. Methods:Two hundred and two BPPV patients who came to the hospital for diagnosis and treatment were collected and divided into two groups by random number table method. Group A had 102 cases for manual reduction, and group B had 100 cases for automatic device reduction. Both groups were given the same medicine-assisted treatment. All patients were followed up 7 to 10 days after reduction treatment. To evaluate the differences in the overall effective rate of treatment, visual analog scale（VAS）, incidence of adverse reactions, treatment time were compared between the two groups. Results:The overall effective rate was 98.03% and 91.00% in group A and group B, respectively, group A was slightly higher than group B（P=0.027）; the difference in VAS scores before and after treatment: group A was 6（4） points, group B was 5（3） , group A is greater than group B（P=0.002）; adverse reaction rates in groups A and B were 4.90% and 8.00%, respectively, group B was slightly higher than group A（P=0.37）; treatment time: group A 6.0（1.0） min in group A and 8.0（2.0） min in group B, group A was significantly shorter than group B（P<0.01）. Conclusion:Both manual and fully automatic device reduction can effectively improve the clinical symptoms of BPPV patients, but for physicians with extensive clinical experience it is recommended to choose manual reduction.

Asymptomatic inguinal hernia: does it need surgical repair? A systematic review and meta-analysis.

BACKGROUND: The aim of this review is to compare the outcomes of surgical repair versus watchful waiting in asymptomatic or minimally symptomatic inguinal hernias. METHODS: Preferred reporting items for systematic reviews and meta-analyses guidelines were employed. We analysed primary outcomes: pain, quality of life, pain during daily activities and visual analogue scale (VAS that measures pain at rest and on movement) and secondary outcomes: postoperative complications and recurrence. RESULTS: Pain and quality of life were not comparable due to differences in the parameters used in different articles. Pain interfering with normal daily activity was evaluated in one study and appears more favourable in the post-repair group respect to the watchful waiting (WW) group (5.1% versus 2.2%). VAS, measured in one study, at 6 months was more favourable in the surgery group (37% versus 44%). After 12 months the outcome was better in the control group than in the repair group (28% versus 30%). Conversion rate of the patient cohorts from watchful waiting to elective surgery was between 35.03% and 57.8%. The meta-analysis did not find significant statistical differences in the two groups examined for postoperative complications [RR = 0.95, 95% CI (0.50, 1.80), P = 0.88], as for hernia recurrence [RR = 1.01, 95% CI (0.50, 2.02), P = 0.98]. CONCLUSION: WW seems to be an acceptable option for the patient with asymptomatic or minimally symptomatic inguinal hernias. Delaying surgical repair until symptoms appear is safe. Acute hernia incarcerations are not particularly frequent. The incidence of chronic pain after the repair is high. Physicians must select patients carefully and explain to them the risks and benefits of surgery.

Diagnostic office hysteroscopy; why is it still painful procedure despite the surgical experience and mini-hysteroscope?

AIM: To evaluate the effect of cervical canal features on pain during outpatient hysteroscopy performed by experienced surgeons using mini-hysteroscope. METHODS: A prospective observational study was conducted on 303 women undergoing diagnostic hysteroscopy without anesthesia. Pain intensity was evaluated using the visual analog scale (VAS) when the cervical canal was passed. The patients were divided into two groups according to the VAS score: painless or mild pain (VAS <4) and moderate or severe pain (VAS ≥ 4). The relationship between cervical canal characteristics (length, version, and flexion positions, history of cervical intervention, stenosis, synechiae), obstetric and gynecological history, preoperative anxiety level, procedure duration, and pain intensity was examined. RESULTS: Moderate pain (4 ≤ VAS < 7) was observed in 38% of patients (n = 117) and 14 patients (5%) experienced severe pain (VAS ≥ 7). In multivariate analysis, nulliparity (p = 0.01; OR, 4.6; 95% CI, 1.7-13.2), postmenopausal state (p = 0.02; OR, 2.2; 95% CI, 1.2-4.3), excessive flexion of the cervix and retroverted uterus (p <0.001; OR, 4.1; 95% CI, 2.0-8.5) were identified as risk factors for a painful procedure. Diagnostic hysteroscopy was successful in 98% of the patients. The pain was the primary cause of the failed hysteroscopy. CONCLUSION: In addition to nulliparity and postmenopausal status, unfavorable features of the cervical canal, such as the excessive flexion position of the cervix and uterine retroversion are significant causes of pain during outpatient hysteroscopy.
