Effectiveness of integrated approach of yoga therapy versus usual care in management on chronic low back pain patients: A randomized controlled pilot study.

BACKGROUND: Chronic low back pain is associated with both psychological and functional limitation. Yoga therapy has been shown to improve both the aspects. The present study was planned to evaluate integrated approach of yoga therapy with usaul care. AIMS: This controlled randomized trial was done to evaluate the clinical and molecular changes resulting from integrated approach of yoga therapy (IAYT) as an adjunct regimen and compared it with usual care for the management of chronic low back pain patients. MATERIAL AND METHODS: We enrolled 29 adult patients with non-specific chronic low back pain (CLBP). Patients were randomly divided into two groups. The control group received the usual care of treatment as per institutional protocol. The yoga group received IAYT as an adjunct to usual care. Primary outcomes were pain intensity assessed by verbal numerical rating scale (VNRS) and functional ability assessed by Modified Oswestry Disability Index (MODI). Secondary outcomes were pain catastrophizing, quality of life, fear of movement related to CLBP, type of pain, levels of ß-endorphin and TNF-α, and salivary CGRP. All parameters were measured at baseline, 1 and 3 months. RESULTS: A Significant decrease in VNRS score at 1 and 3 months was observed in both the groups with the yoga group showing a more significant reduction in pain over time than the control group (p = 0.036). MODI improved significantly only in the yoga group at 1 and 3 months. Intergroup comparison revealed significantly better MODI over time in the yoga group (p < 0.001). DN4, PDQ, PCS, HADS (anxiety), and Euro QOL had a statistically significant improvement at 1 and 3 months in the yoga group compared with the control group. The HADS (depression) had a statistically significant reduction scores in the yoga group at 3 months compared with the control group (p = 0.012). There was a significant reduction in TNF-α values in the yoga group compared with baseline (p = 0.004). CONCLUSION: IAYT therapy helped in addressing the psychological components of pain and improved quality of life patients with chronic low back pain compared with usual care.

Intraoperative Diagnosis of Bilateral Upper Limb Arteriovenous Fistulae in a Child: A Case Report.

Arteriovenous fistulae have not been extensively reported in pediatric patients and are rare for pediatric anesthesiologists to encounter in their routine practice. Awareness of these lesions enables clinicians to avoid giving medications through the anomalous vascular connections. We report a child scheduled for an excision of a sacrococcygeal mass in whom we incidentally diagnosed the presence of arteriovenous fistulae in both his upper limbs. The affected limbs should be avoided and the vessels of the lower limbs should be cannulated for administration of fluid and medications during surgery.

Assessment of impaired cerebral autoregulation and its correlation with neurological outcome in aneurysmal subarachnoid hemorrhage: A prospective and observational study.

Background: Cerebral autoregulation (CA) is crucial for the maintenance of cerebral homeostasis. It can be assessed by measuring transient hyperemic response ratio (THRR) using transcranial Doppler (TCD). We aimed at assessing the incidence of impaired CA (ICA) and its correlation with the neurological outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Methods: One hundred consecutive patients with aSAH scheduled for aneurysmal clipping were enrolled in this prospective and observational study. Preoperative and consecutive 5-day postoperative THRR measurements were taken. Primary objective of the study was to detect the incidence of ICA and its correlation with vasospasm (VS) postclipping, and neurological outcome at discharge and 1, 3, and 12 months was secondary objectives. Results: ICA (THRR < 1.09) was observed in 69 patients preoperatively, 74 patients on the 1st and 2nd postoperative day, 76 patients on 3rd postoperative day, and 78 patients on 4th and 5th postoperative day. Significant VS was seen in 13.4% and 61.5% of patients with intact THRR and deranged THRR, respectively (P < 0.000). Out of 78 patients who had ICA, 42 patients (53.8%) at discharge, 60 patients (76.9%) at 1 month, 54 patients (69.2%) at 3 month, and 55 patients (70.5%) at 12 months had unfavorable neurological outcome significantly more than those with preserved CA. Conclusion: Incidence of ICA assessed in aSAH patients varies from 69% to 78% in the perioperative period. The deranged CA was associated with significantly poor neurological outcome. Therefore, CA assessment using TCD-based THRR provides a simple, noninvasive bedside approach for predicting neurological outcome in aSAH.

Goal-directed Fluid Therapy Versus Conventional Fluid Therapy During Craniotomy and Clipping of Cerebral Aneurysm: A Prospective Randomized Controlled Trial.

BACKGROUND: Fluid imbalance is common after aneurysmal subarachnoid hemorrhage and negatively impacts clinical outcomes. We compared intraoperative goal-directed fluid therapy (GDFT) using left ventricular outflow tract velocity time integral (LVOT-VTI) measured by transesophageal echocardiography with central venous pressure (CVP)-guided fluid therapy during aneurysm clipping in aneurysmal subarachnoid hemorrhage patients. METHODS: Fifty adults scheduled for urgent craniotomy for aneurysm clipping were randomly allocated to 2 groups: group G (n=25) received GDFT guided by LVOT-VTI and group C (n=25) received CVP-guided fluid management. The primary outcome was intraoperative mean arterial pressure (MAP). Secondary outcomes included volume of fluid administered and several other intraoperative and postoperative variables, including neurological outcome at hospital discharge and at 30 and 90 days. RESULTS: There was no difference in MAP between the 2 groups despite patients in group G receiving lower volumes of fluid compared with patients in group C (2503.6±534.3 vs. 3732.8±676.5 mL, respectively; P <0.0001). Heart rate and diastolic blood pressure were also comparable between groups, whereas systolic blood pressure was higher in group G than in group C at several intraoperative time points. Other intraoperative variables, including blood loss, urine output, and lactate levels were not different between the 2 groups. Postoperative variables, including creatinine, duration of postoperative mechanical ventilation, length of intensive care unit and hospital stay, and incidence of acute kidney injury, pneumonitis, and vasospasm were also comparable between groups. There was no difference in neurological outcome at hospital discharge (modified Rankin scale) and at 30 and 90 days (Extended Glasgow Outcome Scale) between the 2 groups. CONCLUSION: Compared with CVP-guided fluid therapy, transesophageal echocardiography-guided GDFT maintains MAP with lower volumes of intravenous fluid in patients undergoing clipping of intracranial aneurysms with no adverse impact on postoperative complications.

Fiberoptic bronchoscopy versus video laryngoscopy guided intubation in patients with craniovertebral junction instability: A cinefluroscopic comparison.

BACKGROUND: Manipulation during endotracheal intubation in patients with craniovertebral junction (CVJ) anomalies may cause neurological deterioration due to underlying instability. Fiberoptic-bronchoscopy (FOB) is better than video laryngoscope (VL) for minimizing cervical spine movement during intubation. However, evidence suggesting superiority of FOB in patients with CVJ instability is lacking. We prospectively compared dynamic movements of the upper cervical spine during intubation using FOB with VL in patients with CVJ anomalies. METHODS: A prospective, randomized, and clinical trial was conducted in 62 patients of American Society of Anaesthesiologist Grade I-II aged between 12 and 65 years with CVJ anomalies. Patients were randomized for intubation under general anesthesia with either VL or FOB. The intubation process was done with application of skeletal traction and recorded cinefluroscopically. The dynamic interrelationship of bony landmarks (horizontal, vertical, and diagonal distances between fixed points on posterior C1 and C2) was analyzed to indirectly calculate alteration of the upper cervical spinal canal diameter (at CVJ). Atlanto-dental interval (ADI) was calculated wherever possible. RESULTS: The alteration in canal diameter (using bony landmarks) at CVJ during intubation was not significant with the use of either VL or FOB (P > 0.05). In 41 patients, where ADI could be measured, ADI was reduced (increased spinal canal diameter) in a greater number of patients in VL group when compared to FOB group (P < 0.05). CONCLUSION: Using rigid skull traction, intubation under general anesthesia with VL offers similar advantage as FOB in terms of the spinal kinematics in patients with CVJ anomalies/instability. Nevertheless, greater number of patients intubated with VL may have an advantage of increased cervical spinal canal diameter when compared to FOB.

Postoperative cardiorespiratory arrest in a case of cervical meningocele.

BACKGROUND: Meningoceles are congenital herniation of meninges and cerebrospinal fluid (CSF) through the skull and are bereft of any cerebral tissue. They are commonly found over the anterior fontanelle. Although some cases of cervical dysraphism have been described in the literature, a true meningocele has rarely been seen. The child usually presents with hydrocephalus with features of raised increased intracranial pressure. Sensory, motor, and sphincter functions may be involved depending on the level of lesion. Closure of meningocele should be ideally done within the first 48 h of birth. CASE DESCRIPTION: Complications associated with meningocele range from learning disabilities, seizures, and bowel dysfunction to complete paralysis below the level of the lesion. The postoperative complications reported are wound infection, CSF leak/collection, urinary tract infection, deterioration of deficit, and death. Here, we present a postoperative case of an 11-month-old child with cervical meningocele who had an unusual complication almost 2 h after an uneventful surgery in the form of sudden cardiorespiratory arrest was revived successfully. CONCLUSION: A meningocele surgery is usually not associated with severe postoperative complications which can be encountered in meningomyelocele surgery. Here, in our case, the child with uneventful meningocele surgery arrested 2 h postsurgery with the possible cause being cervical cord edema. Hence, a lesson was learned that strict vigilance is also required in postoperative care for meningocele patients.

The Safety and Efficacy of Bevacizumab for Radiosurgery - Induced Steroid - Resistant Brain Edema; Not the Last Part in the Ship of Theseus.

BACKGROUND: Radiation-induced brain edema (RIBE) is a serious complication of radiation therapy. It may result in dramatic clinico-radiological deterioration. At present, there are no definite guidelines for management of the complication. Corticosteroids are the usual first line of treatment, which frequently fails to provide long-term efficacy in view of its adverse complication profile. Bevacizumab has been reported to show improvement in cases of steroid-resistant radiation injury. The objective of this study is to evaluate the role of Bevacizumab in post-radiosurgery RIBE. MATERIAL AND METHODS: Since 2012, 189 out of 1241 patients who underwent radiosurgery at our institution developed post-radiosurgery RIBE, 17 of which did not respond to high-dose corticosteroids. We systematically reviewed these 17 patients of various intracranial pathologies with clinic-radiological evidence of RIBE following gamma knife radiosurgery (GKRS). All patients received protocol-based Bevacizumab therapy. The peer-reviewed literature was evaluated. RESULTS: 82 percent of the patients showed improvement after starting Bevacizumab. The majority began to improve after the third cycle started improvement after the third cycle of Bevacizumab. Clinical improvement preceded radiological improvement by an average of eight weeks. The first dose was 5 mg/kg followed by 7.5-10 mg/kg at with two-week intervals. Bevacizumab needs to be administered for an average of seven cycles (range 5-27, median 7) for best response. Steroid therapy could be tapered in most patients by the first follow-up. One patient did not respond to Bevacizumab and needed surgical decompression for palliative care. One noncompliant patient died due to radiation injury. CONCLUSION: Bevacizumab is a effective and safe for treatment of RIBE after GKRS. A protocol-based dose schedule in addition to frequent clinical and radiological evaluations are required. Bevacizumab should be considered as an early treatment option for RIBE.
