Christopher S, Dutta S, Gopal TVS. Bilateral pericapsular end nerve blocks for steroid-induced avascular necrosis following COVID-19 infection requiring bilateral total hip replacement. World J Anesthesiol 2024; 13:90514. [DOI: 10.5313/wja.v13.i1.90514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 01/05/2024] [Accepted: 02/25/2024] [Indexed: 03/08/2024] [Imported: 03/08/2024] Open
Abstract
BACKGROUND Osteonecrosis or avascular necrosis (AVN) of the hip was one of the dreaded complications of coronavirus disease 2019 (COVID-19), which emerged in patients who received steroid therapy. Corticosteroids have been a mainstay in the treatment protocol of COVID-19 patients. Popular corticosteroid drugs used in patients suffering from COVID-19 were intravenous (IV) or oral dexamethasone, methylprednisolone or hydrocortisone. The use of such high doses of corticosteroids has shown very positive results and has been lifesaving in many cases. Still, long-term consequences were drug-induced diabetes, osteoporosis, Cushing syndrome, muscle wasting, peripheral fat mobilization, AVN, hirsutism, sleep disturbances and poor wound healing. A significant number of young patients were admitted for bilateral total hip replacements (THR) secondary to AVN following steroid use for COVID-19 treatment.
AIM To assess the efficacy of bilateral pericapsular end nerve group (PENG) blocks in patients posted for bilateral THR post-steroid therapy after COVID-19 infection and assess the time taken to first ambulate after surgery.
METHODS This prospective observational study was conducted between January 2023 and August 2023 at Care Hospitals, Hyderabad, India. Twenty young patients 30-35 years of age who underwent bilateral THR were studied after due consent over 8 months. All the patients received spinal anaesthesia for surgery and bilateral PENG blocks for postoperative analgesia.
RESULTS The duration of surgery was 2.5 h on average. Seventeen out of twenty patients (85%) had a Visual Analog Score (VAS) of less than 2 and did not require any supplementation. One patient was removed from the study, as he required re-exploration. The remaining two patients had a VAS of more than 8 and received IV morphine post-operatively as a rescue analgesic drug. Fifteen out of seventeen patients (88.2%) could be mobilized 12 h after the procedure.
CONCLUSION Osteonecrosis or AVN of the hip was one of the dreaded complications of COVID-19, which surfaced in patients who received steroid therapy requiring surgical intervention. Bilateral PENG block is an effective technique to provide post-operative analgesia resulting in early mobilization and enhanced recovery after surgery.

Obi MF, Ubhi M, Namireddy V, Noel C, Sharma M, Campos FN, Garg Y. Malignant hyperthermia as a rare complication of local lidocaine injection: A case report. World J Anesthesiol 2023; 12:1-7. [DOI: 10.5313/wja.v12.i1.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 06/14/2023] [Accepted: 07/03/2023] [Indexed: 07/27/2023] Open
Abstract
BACKGROUND Malignant hyperthermia (MH) is a hypermetabolic disorder of skeletal muscles triggered by exposure to volatile anesthetics and depolarizing muscular relaxants. It manifests with clinical presentations such as tachycardia, muscle rigidity, hyperpyrexia, and rhabdomyolysis in genetically predisposed individuals with ryanodine receptor or calcium voltage-gated channel subunit alpha1 S mutations. Local anesthetics, such as lidocaine, are generally considered safe; however, complications can arise, albeit rarely. Lidocaine administration has been reported to induce hypermetabolic reactions resembling MH in susceptible individuals. The exact mechanism by which lidocaine might trigger MH is not fully understood. Although some mechanisms are postulated, further research is needed for a better understanding of this.
CASE SUMMARY We present the case of MH in a 43-year-old male patient with an unknown genetic predisposition following a lidocaine injection during a dental procedure. This case serves as a reminder that while the occurrence of lidocaine-induced MH is rare, lidocaine can still trigger this life-threatening condition. Therefore, caution should be exercised when administering lidocaine to individuals who may be susceptible to MH. It is important to note that prompt intervention played a crucial role in managing the patient’s symptoms. Upon recognizing the early signs of MH, aggressive measures were initiated, including vigorous intravenous normal saline administration and lorazepam. Due to the effectiveness of these interventions, the administration of dantrolene sodium, a specific antidote for MH, was deferred.
CONCLUSION This case highlighted the significance of vigilant monitoring and swift action in mitigating the detrimental effects of lidocaine-induced MH. Caution should be exercised when administering lidocaine to individuals who may be predisposed to MH. It is very important to be aware and vigilant of the signs and symptoms of MH as early recognition and treatment intervention are important to prevent serious complications to decrease mortality.

Abstract
BACKGROUND Heart failure is generally regarded as a progressive and irreversible medical condition. The EVAHEART is an implantable left ventricular assist system.
CASE SUMMARY We report the anesthesia management of a 56-year-old male patient with dilated cardiomyopathy undergoing an EVAHEART implantation. Transesophageal echocardiography is crucial to ensure the correct positioning of the device and the proper aortic valve outflow. Because the continuous blood flow device functions best under low systemic and pulmonary vascular resistance, milrinone is the preferred drug. Our patient was accompanied by pulmonary hypertension, so during the operation, nitric oxide was used to reduce pulmonary artery pressure.
CONCLUSION The cardiac output achieved by the patient with the assistance of EVAHEART can reach 4 L/min, which of course depends on the front load, rear load, and pump speed.

Abstract
BACKGROUND In anesthesia practice, orotracheal intubation remains the primary concern of the anesthesiologist. The introduction of video laryngoscopy (VL) has increased the success rate of orotracheal intubation; however, conflicting results have been reported regarding the usefulness of the current technique with VL in clinical practice.
AIM To describe a modification to improve intubation with VL, followed by evaluation of the practice in vivo.
METHODS First, a mannequin trial was conducted with operators having different experience and background. Then, a retrospective analysis was performed for an > 1-year period with patients who underwent general anesthesia with orotracheal intubation. The endotracheal tube used had been pre-formed with two curves. Stepwise intubation had been performed with direct eye vision, followed by screen assistance and rotation of the tube as needed to direct it toward the glottis. In the mannequin trial, the outcome measures were quantification of torque (force with angular acceleration during levering), need for external maneuvers, and time to intubate. In the clinical experience, orotracheal intubation used VL (pre-formed tube) or direct laryngoscopy (DL) at the anesthetist’s discretion and throat discomfort was reported by the patient.
RESULTS In the mannequin trials using VL, there was less torque with the pre-formed tube than with a regular tube (8% and 65%, respectively). The first-pass rate was higher with the pre-formed tube (95%) than with a regular tube (81%). However, the time to intubate was longer with the pre-formed tube than with a regular tube (22 s and 12 s, respectively). In clinical practice, 562 patients underwent surgery under general anesthesia with orotracheal intubation using either VL (n = 244) or DL (n = 318) at the discretion of the attending anesthetist. VL was specifically planned in 62 of the patients, due to anticipated difficulty. Second attempts by readjustment of the curve of the tube were significantly fewer with VL than with DL (10% vs 18%). Throat discomfort was reported by fewer patients who underwent VL than those who underwent DL (6% vs 24%).
CONCLUSION Pre-formed endotracheal tube with stepwise insertion produces less torque, fewer external maneuvers and higher first-pass success rate during VL intubation. Further, prospective studies are warranted.

Desai TV, Dhir A, Quan D, Zamper R. Intraoperative management of liver transplant in a patient with an undiagnosed ventricular septal defect: A case report. World J Anesthesiol 2021; 10:1-6. [DOI: 10.5313/wja.v10.i1.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 08/11/2021] [Accepted: 09/26/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The intraoperative management of patients undergoing orthotopic liver transplantation (OLT) frequently encounters hemodynamic instability after reperfusion of the new liver graft. The resulting post-reperfusion syndrome is characterized by an increase in pulmonary vascular resistance and decrease in systemic vascular resistance. In the presence of a left to right intracardiac shunt, this hemodynamic perturbance can lead to shunt reversal followed by hypoxemia and embolization of air and debris into the systemic circulatory system.
CASE SUMMARY A 43 years-old male with end-stage liver disease due to primary sclerosing cholangitis complicated by portal hypertension and hepatocellular carcinoma presented for an OLT. A bedside transthoracic echocardiography (TTE) was performed immediately before the procedure and unexpectedly identified a ventricular septal defect (VSD). The patient and the surgical team agreed to proceed with the surgery as it was a time critical donation after circulatory organ death. We developed an intraoperative plan to optimize pulmonary and systemic pressures using vasoactive support, optimized mechanical ventilation, and used transesophageal echocardiography (TEE) for intraoperative monitoring. During reperfusion, considerable turbulent flows with air were noted in the right ventricle, but no air was visualized in the left ventricle. Color flow Doppler showed no reversal flow in the VSD. At the end of the procedure, the patient was extubated in the operating room without complication and was transferred to the transplant unit for recovery.
CONCLUSION Our case highlights the importance of echocardiography in the perioperative assessment of patients undergoing liver transplantation. The TTE findings obtained immediately before the procedure and the real-time use of intraoperative TEE to modify our management during the critical phases of the transplant resulted in continuity of care and a good surgical outcome for this patient.

Abstract
Low dose corticosteroids to adult patients with coronavirus disease 2019 (COVID-19) and refractory shock was given some evidence, the evidence was of low quality given particularly for shock-reversal. Evidence. However bacterial sepsis may not provide a similar evidence like in a viral related one. We think that suggesting steroids for COVID-19 may not be adequate in the current time and future data analysis should be directed to find possible evidence in a matched population

Abstract
BACKGROUND Cement-related embolism is a rare but potentially fatal complication in spinal surgery. Cardiac echocardiography can provide valuable information for the early identification.
CASE SUMMARY A 66-year-old woman who underwent lumbar vertebroplasty and internal fixation under general anesthesia experienced an episode of supraventricular tachycardia and ventricular tachycardia at the end of surgery. Point-of-care echocardiogram revealed a foreign body in the right heart. After conservative treatment in the intensive care unit, her family decided on comfort care and she expired.
CONCLUSION Transthoracic echocardiography may provide early valuable information in patients undergoing vertebroplasty, and mild-moderate pericardial effusion may be a significant sign of a poor outcome.

Abstract
BACKGROUND The usage of bronchoscopy during percutaneous dilatational tracheostomy remains under debate. The proponents of bronchoscopy advocating safety of the procedure, whereas the critics raising the concerns about the cost, possible delay in the procedure, and waiting for the device.
CASE SUMMARY We are highlighting a case of percutaneous dilatational tracheostomy where bronchoscopy aided in diagnosing a rare situation of wire entrapment within the endotracheal tube, treated by withdrawing the wire from the endotracheal tube with good outcome.
CONCLUSION The bronchoscopy guided approach permitted early diagnosis and helped to end the procedure without complication or possible major surgery in a case of accidental wire puncture of the endotracheal tube.

Abstract
With the advancement of technology and health sciences, health care delivery costs are steadily increasing. This affects both households and governments. Unfortunately, the present truth is that health has become an essential but unaffordable commodity. This is very concerning. Quality, up-to-date, cost-effective health care delivery is one of the prime objectives, and focuses on administration and health care authority. As the per capita spent on health from public/government funds is very poor in developing countries, the responsibility of cost-effective health care delivery falls primarily on the shoulder of the treating physicians. Anesthesiologists are becoming an indispensable part of health care delivery, having a diverse role in the emergency, critical care, pain, and perioperative care of patients. As the population ages, the need for surgical care is also increasing. Therefore, the anesthesiologist can also play a more significant role in delivering cost-effective health care, and minimize the cost without affecting the quality. This brief narrative review analyzes the current practice of anesthesiologists in two prime areas in the context of cost-savings: Preoperative investigation and low/minimal flow anesthesia.

Abstract
BACKGROUND Fascia iliaca compartment blocks (FIBs) have been used to provide postoperative analgesia after total hip arthroplasty (THA). However, evidence of their efficacy remains limited. While pain control appears to be satisfactory, quadriceps weakness may be an untoward consequence of the block. Prior studies have shown femoral nerve blocks and fascia iliaca blocks as being superior for pain control and ambulation following THA when compared to standard therapy of parenteral pain control. However, most studies allowed patients to ambulate on post-operative day (POD) 2-3, whereas new guidelines suggest ambulation on POD 0 is beneficial.
AIM To determine the effect of FIB after THA in patients participating in an enhanced recovery after surgery (ERAS) program.
METHODS We conducted a retrospective analysis of patients undergoing THA with or without FICBs and their ability to ambulate on POD 0 in accordance with ERAS protocol. Perioperative data was collected on 39 patients who underwent THA. Demographic data, anesthesia data, and ambulatory outcomes were compared.
RESULTS Twenty patients had FIBs placed at the conclusion of the procedure, while 19 did not receive a block. Of the 20 patients with FIB, only 1 patient was able to ambulate. Of the 19 patients without FIB blocks, 17 were able to ambulate. All patients worked with physical therapy 2 h after arriving in the post-anesthesia care unit on POD 0.
CONCLUSION Our data suggests an association between FIB and delayed ambulation in the immediate post-operative period.

Abstract
Postoperative urinary retention (POUR) is one of the postoperative complications which is often underestimated and often gets missed and causes lot of discomfort to the patient. POUR is essentially the inability to void despite a full bladder in the postoperative period. The reported incidence varies for the wide range of 5%-70%. Multiple factors and etiology have been reported for occurrence of POUR and these depend on the type of anaesthesia, type and duration of surgery, underlying comorbidities, and drugs used in perioperative period. Untreated POUR can lead to significant morbidities such as prolongation of the hospital stay, urinary tract infection, detrusor muscle dysfunction, delirium, cardiac arrhythmias etc. This has led to an increasing focus on early detection of POUR. This review of literature aims at understanding the normal physiology of micturition, POUR and its predisposing factors, complications, diagnosis and management with special emphasis on the role of ultrasound in POUR.

Lumbar radiculopathy (LR) is a term used to describe a pain syndrome caused by compression or irritation of nerve roots in the lower back. The surgery cost for LR increased by 23% annually during 1992-2003 in the developed country. Although it is one of most common complaints in clinical practice, the diagnosis for LR is still very challenging. Here we discuss the current tools of LR diagnosis and highlight the needs to develop new diagnosis tools for LR.

Abstract
Neuropathic pain is a chronic syndrome caused by direct damage to or disease of the somatosensory nervous system. The lack of safe, adequate and sustained pain relief offered by present analgesic treatments is most alarming. While many treatment options are available to manage chronic pain, such as antidepressants, non-steroidal anti-inflammatory agents, opioids, and anticonvulsants, chronic neuropathic pain remains largely unmanaged. Compounding the dilemma of ineffective chronic pain treatments is the need to provide relief from suffering and yet not contribute to the scourge of drug abuse. A recent epidemic of addiction and accidental drug prescription overdoses parallel the increased use of opioid treatment, even though opioids are rarely an effective treatment of relieving chronic pain. To make matters worse, opioids may contribute to exacerbating pain, and side-effects such as cognitive impairment, nausea, constipation, development of tolerance, as well as their potential for addiction and overdose deaths exist. Clearly, there is an urgent need for alternative, non-opiate treatment of chronic pain. Innovative discoveries of pertinent brain mechanisms and functions are key to developing effective, safe treatments. Pioneering work has revealed the essential effects of the pleiotropic mediator tumor necrosis factor (TNF) on brain functioning. These studies establish that TNF inhibits norepinephrine release from hippocampal neurons, and show that excess TNF production within the hippocampus occurs during neuropathic pain, which mobilizes additional mechanisms that further inhibit norepinephrine release. Significantly, it has been verified that elevated levels of TNF in the brain are actually required for neuropathic pain development. Since TNF decreases norepinephrine release in the brain, enhanced TNF levels would prevent engagement of the norepinephrine descending inhibitory neuronal pain pathways. Increased levels of TNF in the brain are therefore critical to the development of neuropathic pain. Therefore, strategies that decrease this enhanced TNF expression in the brain will have superior analgesic efficacy. We propose this novel approach of targeting the pathologically high levels of brain TNF as an effective strategy in the treatment of the devastating syndrome of chronic pain.

Abstract
AIM To determine if video laryngoscopy (VL) has significantly impacted management of difficult airways by decreasing the rate of awake fiberoptic intubation (FOI).
METHODS Anesthetic records of 3723 patients who underwent general anesthesia at Rush University Medical Center were reviewed over a 2-mo period prior to the introduction of VLs in 2009 (“pre-VL” group) and over the same 2-mo period after the introduction of VLs in 2012 (“post-VL” group). Patient records with predicted difficult airways based on pre-operative airway examination were analyzed. The primary outcome was rate of awake FOI.
RESULTS To control for possible factors that may influence the FOI rate, a logistic regression was performed with these factors included as covariates. The rate of awake FOI was 13.1% in pre-VL group compared to 9.0% in post-VL group. Although this decrease was not statistically significant individually (P = 0.1768), it showed a trend toward significance when covariates were accounted for (P = 0.0910). Several factors predicting a higher likelihood of awake FOI were found to be statistically significant: Morbid obesity (larger BMI P = 0.0154, OR = 1.5 per 10 point BMI increase), male gender (P = 0.0026, OR = 3.0) and a higher el-Ganzouri airway score (P = 0.0007, OR = 1.5). Although VLs were seen to be used to intubate 51% of predicted difficult airways, the rate of awake FOI has not significantly changed.
CONCLUSION Although VL may continue to grow in popularity, the most difficult airways are still managed using awake FOI.

Abstract
Burn injuries create severe pain and psychological distress that are highly variable between patients. Distinct types of pain during various stages of injury and recovery make treatment complex. Standard pharmacological treatment of pain can have adverse effects and is not effective in treating anxiety and other psychological issues. Researchers have proposed that integrating clinical hypnosis as a complementary therapy can be highly beneficial to burn patients and their healthcare providers. The existing literature is reviewed and specific hypnosis techniques are discussed. Evidence exists indicating that adjunctive hypnosis is effective at reducing pain and procedural anxiety. Implementing a multidisciplinary burn care team that includes clinical hypnosis and focuses on the patients’ psychological health as well as pain reduction is likely to result in faster healing and reduced distress for patients and caregivers alike.

Abstract
Exsanguination from trauma, gastrointestinal bleeding, and obstetric hemorrhage remains a major source of mortality across the planet. Continued research into resuscitation strategies and evolving technology and blood product storage has allowed for patient to undergo very large volume transfusions, even to the point of replacing a patient’s blood volume several times over. As massive transfusions have become more common, more studies have been performed delineating the exact patient population that would benefit, start- and stop-points of transfusions, complications and avoidance of the same. We discuss these points and provide information and strategies for massive transfusion.

Abstract
Intraoperative awareness is the explicit recall of sensory perceptions during general anesthesia. I presume the epidemiology and characteristics of intraoperative awareness from these surveys in Japan. A questionnaire survey was conducted via the Internet. The first survey was conducted in 2008. Our survey showed 17% of anesthesiologists experienced definite or possible awareness. The second survey was conducted to evaluate the first survey in detail in 2008. A total of 172 anesthesiologists answered. The total number of reported anesthetic cases was 85156. Twenty-four cases of definite or possible awareness were reported by 21 anesthesiologists. The most surprising finding was total intravenous anesthesia (TIVA) was used in 21 of the 24 cases. The third survey was conducted in 2011 as a continuous survey. Six cases of definite or possible awareness were reported by six anesthesiologists (7%). Two cases were maintained by TIVA, and 2 cases were sevoflurane. The survey showed 76% anesthesiologists routinely use bispectral index (BIS) for TIVA, but for sevoflurane only 27% anesthesiologists routinely use BIS. The incidence of intraoperative awareness decreased in the third survey. The continuous survey revealed the current status of daily anesthesia and the results might be used to prevent the awareness during general anesthesia.

Abstract
Arrhythmogenic right ventricular dysplasia (ARVD) is an inherited heart muscle disease. Myocyte apoptosis and fibro-fatty scar tissue predisposes patients to malignant ventricular arrhythmias. Patients may present to variety of surgical procedures with diagnosed ARVD. Surgical insult, catecholamine surge and physiological disturbance can be hazardous on the vulnerable myocardium and may result in life-threatening ventricular tachycardia or sudden cardiac death in the perioperative period. Anaesthetists have particular role in perioperative management of this patient population, meticulous perioperative planning, close haemodynamic monitoring and maintenance of physiological stability throughout helps to avoid devastating perioperative loss.

[DOI: 10.5313/wja.v5.i3.67] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Revised: 07/17/2016] [Accepted: 09/18/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To compare the efficacy of intrathecal morphine and single shot femoral nerve block for patients undergoing primary total knee arthroplasty.
METHODS Data was extracted from electronic medical records and case-paper record files of patients who underwent unilateral primary total knee arthroplasty under spinal anesthesia using bupivacaine 12.5 mg with intrathecal morphine (ITM) 0.2 mg and under general anesthesia (GA) with single shot femoral nerve block (FNB) using 20 mL 0.5% bupivacaine at our hospital in 2013 and 2014. All patients had received peri-articular infiltration as per the hospital protocol. Data for gender, age, weight, American Society of Anesthesiologists status, total surgical time, postoperative pain score using visual analogue scale (VAS) from 1 to 10 at 6 h, 12 h and 24 h postoperatively, 24 h opioid consumption, use of oral multimodal analgesia, postoperative high dependency unit (HDU) admission and the time to discharge from the hospital was collected. The data was analyzed using Mann-Whitney U test for continuous variables and Fischer’s exact-t-test for categorical variables.
RESULTS Twenty-two patients in ITM group and 32 patients in FNB group were analyzed. Median pain scores using VAS in ITM group were significantly lower at 6 h (0.0 vs 2.0, P < 0.001), 12 h (0.0 vs 2.0, P < 0.001) and 24 h (0.0 vs 2.0, P < 0.001) postoperatively. Also, postoperative morphine consumption in ITM group was significantly lower (P < 0.001). However, median of non-steroid anti-inflammatory drug unit requirement in 24 h postoperatively was statistically significant higher in ITM compared to FNB group (2.0 vs 1.0, P = 0.025). The difference in postoperative paracetamol consumption in 24 h was not statistically significant (P = 0.147). There was no significant difference in the postoperative HDU admission or time to discharge from the hospital. No respiratory depression in either group was noticed.
CONCLUSION The ITM group patients had much lower pain scores and morphine requirement in the first 24 hour postoperatively compared to FNB group.

Abstract
Fifteen percent to forty percent of patients present with persistent disabling neck pain or radicular pain after cervical spine surgery. Persistent pain after cervical surgery is called cervical post-surgery syndrome (CPSS). This review investigates the literature about interventional pain therapy for these patients. Because different interventions with different anatomical targets exist, it is important to find the possible pain source. There has to be a distinction between radicular symptoms (radicular pain or radiculopathy) or axial pain (neck pain) and between persistent pain and a new onset of pain after surgery. In the case of radicular symptoms, inadequate decompression or nerve root adherence because of perineural scarring are possible pain causes. Multiple structures in the cervical spine are able to cause neck pain. Hereby, the type of surgery and also the number of segments treated is relevant. After fusion surgery, the so-called adjacent level syndrome is a possible pain source. After arthroplasty, the load of the facet joints in the index segment increases and can cause pain. Further, degenerative alterations progress. In general, two fundamentally different therapeutic approaches for interventional pain therapy for the cervical spine exist: Treatment of facet joint pain with radiofrequency denervation or facet nerve blocks, and epidural injections either via a transforaminal or via an interlaminar approach. The literature about interventions in CPSS is limited to single studies with a small number of patients. However, some evidence exists for these procedures. Interventional pain therapies are eligible as a target-specific therapy option. However, the risk of theses procedures (especially transforaminal epidural injections) must be weighed against the benefit.

Abstract
Treatment for chronic pain is frequently unsuccessful or characterized by side-effects. The high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) has been suggested in the management of refractory chronic pain. Various studies have shown that HF-rTMS sessions of long-duration applied at primary motor cortex induce pain relief through mechanisms of plastic changes. Efficacy of rTMS mostly depends on stimulation parameters, but this aspect requires better characterization. A rationale to target other cortical areas exists. Current data are promising, but a careful analysis of stimulation settings and maintenance treatment design are need.

Abstract
Most of the orthodontic patients experience pain during treatment and this significantly influences their attitudes and the approach towards treatment. A number of factors that influence pain response include age, gender, personal pain threshold, mood and stress level of the person, cultural differences and types of orthodontic treatment. Pain is a often overlooked subject by orthodontists, it is nevertheless important to understand the source and mechanism of the pain that occurs during treatment, as well as the methods for managing and controlling this pain. This review attempts to overview the mechanism, duration and current management strategies of orthodontic treatment.

Abstract
Gastrointestinal endoscopy is the gold standard in the examination and the treatment of the diseases of gastrointestinal system, but the disadvantage of being painful process. At this point the sedative and analgesic agents may be important. Dexmedetomidine is a new sedoanalgesic agent which is alternative to benzodiazepines and opioids. It has analgesia, amnesia, sedative and anxiolytic properties. The use of dexmedetomidine as the sole anesthetic agent and as the adjuvant analgesic agent has been published but has not been approved because of the inconsistency of efficacy and safety. The author has been collected the published papers in the literature. This article is aimed to describe the use of dexmedetomidine in various gastrointestinal endoscopic procedures.

Abstract
We agree with the editorial published by Feng et al concerning the insufficient routine monitoring of tracheal tube cuff pressure (TTCP) by anesthesiologists, and propose an improvised technique that can facilitate and promote such routine monitoring by intensive care staff who attend to patients receiving mechanical ventilation. Insufficient monitoring of tracheal cuff pressure has also been documented for intensive care unit nurses. Measurements of cuff pressure are beneficial when used in management of air leakage around an endotracheal tube, and can be easily obtained with the aid of a personalized and simple technique performed using materials that are readily available in all hospitals. Other investigators have previously demonstrated the usefulness of employing an improvised technique. We considered that possible disadvantages are similar to those encountered when using standardized equipment. With our improvised technique, we seek to promote among the nursing staff the determination of the TTCP in intubated patients to reduce the risk of related medical complications.
