Gamma Knife Stereotactic Radiosurgery

Abstract BACKGROUND: Trigeminal neuralgia (TN) that recurs after surgery can be difficult to manage. OBJECTIVE: To define management outcomes in patients who underwent gamma knife stereotactic radiosurgery (GKSR) after failing 1 or more previous surgical procedures. METHODS: We retrospectively reviewed outcomes after GKSR in 193 patients with TN after failed surgery. The median patient age was 70 years (range, 26-93 years). Seventy-five patients had a single operation (microvascular decompression, n = 40; glycerol rhizotomy, n = 24; radiofrequency rhizotomy, n = 11). One hundred eighteen patients underwent multiple operations before GKSR. Patients were evaluated up to 14 years after GKSR. RESULTS: After GKSR, 85% of patients achieved pain relief or improvement (Barrow Neurological Institute grade I-IIIb). Pain recurrence was observed in 73 of 168 patients 6 to 144 months after GKSR (median, 6 years). Factors associated with better long-term pain relief included no relief from the surgical procedure preceding GKSR, pain in a single branch, typical TN, and a single previous failed surgical procedure. Eighteen patients (9.3%) developed new or increased trigeminal sensory dysfunction, and 1 developed deafferentation pain. Patients who developed sensory loss after GKSR had better long-term pain control (Barrow Neurological Institute grade I-IIIb: 86% at 5 years). CONCLUSION: GKSR proved to be safe and moderately effective in the management of TN that recurs after surgery. Development of sensory loss may predict better long-term pain control. The best candidates for GKSR were patients with recurrence after a single failed previous operation and those with typical TN in a single trigeminal nerve distribution.

BACKGROUND: Osmotic release oral system (OROS®) hydromorphone is a potent, long-acting opioid analgesic, effective and safe for controlling cancer pain in patients who have received other strong opioids. To date, few studies have examined the efficacy of hydromorphone for pain relief in opioid-naive cancer patients.OBJECTIVES: A prospective, open-label, multicentre trial was conducted to determine the efficacy and tolerability of OROS hydromorphone as a single and front-line opioid therapy for patients experiencing moderate to severe cancer pain.METHODS: OROS hydromorphone was administered to patients who had not previously received strong, long-acting opioids. The baseline evaluation (visit 1) was followed by two evaluations (visits 2 and 3) performed two and 14 weeks later, respectively. The starting dose of OROS hydromorphone was 4 mg/day and was increased every two days when pain control was insufficient. Immediate-release hydromorphone was the only accepted alternative strong opioid for relief of breakthrough pain. The efficacy, safety and tolerability of OROS hydromorphone, including the effects on quality of life, and patients’ and investigators’ global impressions on pain relief were evaluated. The primary end point was pain intensity difference (PID) at visit 2 relative to visit 1 (expressed as %PID).RESULTS: A total of 107 patients were enrolled in the present study. An improvement in pain intensity of >50% (≥50% PID) was observed in 51.0% of the full analysis set and 58.6% of the per-protocol set. The mean pain score, measured using a numerical rating scale, was significantly reduced after two weeks of treatment, and most adverse events were manageable. Quality of life also improved, and >70% of patients and investigators were satisfied with the treatment.CONCLUSIONS: OROS hydromorphone provided effective pain relief and improved quality of life in opioid-naive cancer patients. As a single and front-line treatment, OROS hydromorphone delivered rapid pain control.

Background: Failed back surgery syndrome is a common clinical entity for which spinal cord stimulation has been found to be an effective mode of analgesia, but with variable success rates. Objective: To determine if focal stimulation of the dorsal columns with a transverse tripolar lead might achieve deeper penetration of the electrical stimulus into the spinal cord and therefore provide greater analgesia to the back. Design: Case report. Methods: We describe a 42-year-old female with failed back surgery syndrome that had greater back pain than leg pain. The tripolar lead configuration was achieved by placing percutaneously an octapolar lead in the spinal midline followed by 2 adjacent quadripolar leads, advanced to the T7-T10 vertebral bodies. Results: Tripolar stimulation pattern resulted in more than 70% pain relief in this patient during the screening trial, while stimulation of one or 2 electrodes only provided 20% pain relief. After implantation of a permanent tripolar electrode system with a single rechargeable battery, the pain relief was maintained for one year. Conclusion: This is case report describing a case of a patient with chronic low back pain with a diagnosis of failed back surgery syndrome in which transverse tripolar stimulation using an octapolar and 2 quadripolar leads appeared to be beneficial. The transverse tripolar system consists of a central cathode surrounded by anodes, using 3 leads. This arrangement may contribute to maximum dorsal column stimulation with minimal dorsal root stimulation and provide analgesia to the lower back.

Aims and Objective. Pain is a common problem associated with postoperative orthopedic patients; the current study is aimed at evaluating music intervention as an alternative method to control pain. Methodology. The experimental design of the current study was comparative, descriptive, and quasi-experimental. 38 postoperative orthopedic patients were equipped with pocket-size MP3 players with prerecorded music tracks (instrumental and lyrical) in Hindi, English, and Urdu. After that, pre-post-pain scores were recorded with the help of designed brief patient logs. Ultimately, a satisfactory survey was completed at discharge. Major Findings. It was found that during the intervention of music, the pain was significantly reduced from 5.40 to 2.98. There was a slight relationship between listening time and pain relief. It was also found that the feedback was extremely positive and each patient suggested the use of music to others with 96.6% recommendation. Conclusion. From the current study, it was found that music intervention can be beneficial to postoperative patient pain control. Further, it is hoped that the findings of the current experimental work will lead to improvements in the care of postoperative patients.

Background: Pudendal neuropathy is a tunnel syndrome characterized by pelvic pain and may include bowel, bladder, or sexual dysfunction or a combination of these. One treatment method, pudendal nerve perineural injections (PNPIs), uses infiltration of bupivacaine and corticosteroid around the nerve to provide symptom relief. Bupivacaine also anesthetizes the skin in the receptive field of the nerve that is injected. Bupivacaine offers rapid pain relief for several hours while corticosteroid provides delayed pain control often lasting 3 to 5 weeks. Not all pudendal nerve blocks may provide complete pain relief but long-term pain control from the steroid appears to be associated with immediate response to bupivacaine. We offer a method of evaluating the quality of a pudendal block on the day it is performed using pinprick sensation evaluation. Objective: To demonstrate that pinprick sensory changes provide a simple and rapid method of measuring response to local anesthetic and pain reduction provided by a PNPI on the day it is performed. This response defines the quality of each PNPI. Study Design: This is a case series based on retrospective review of a private practice database that is maintained by HealthEast hospitals in Minnesota. Database information includes standard physical examination, recording techniques, and treatment processes that had been in place for several years. Setting: Private practice in United States. Methods: Patients with a diagnosis of pudendal neuropathy are treated with PNPIs. Two hours after each block, 2 endpoints are measured: response to a sensory pinprick examination of the pudendal territory and difference in patient-reported pain level before and after nerve block. Fifty-three men from a private practice treating only pelvic pain received the treatment in 2005. Reported pain level was not recorded for 2 patients. Results: Bupivacaine in perineural injections produces varying degrees of analgesia or hypalgesia to pinprick. Normal pinprick response suggests pudendal nerves were not penetrated by bupivacaine. Patient responses varied from complete, i.e. all 6 branches anesthetized to none. Most men had 2 – 5 nerve branches anesthetized. One man had a single nerve branch that responded to bupivacaine. Three men failed to respond to local anesthetic. Changes in pre-PNPI to post-PNPI pain scores were significantly decreased (n = 51, P-value < 0.0001), indicating that bupivacaine in the PNPI reduced pain. Forty-one patients (80.4%) indicated less pain after the procedure and only 2 patients (4.0%) indicated more pain. The number of nerve branches successfully anesthetized was also significantly correlated with change in score. On average, an additional successful nerve branch anesthetized corresponded to a drop of about 0.66 in the change score (n = 51, P - value = 0.0005). Conclusion: PNPIs relieve pain. Anesthesia affected all 6 pudendal nerve branches in only 13.2% of patients. Complete pain relief occurred in 39.2%. This argues against use of perineural pudendal blockade as a diagnostic test. Pain relief after PNPI is associated with number of nerve branches that are anesthetized. At 2 hours after a PNPI its quality (the number of the 6 nerve branches with reduced response to pinprick from the perineural local anesthetic) is associated with subjective reduction of pain.

Introduction: There are many complications for patients with post cesarean section relative pain. So it delays in discharging or increasing in hospital stay. The objective of this study was a comparison between Tramadol and Meperidine according to pain relief or other possible complications in post cesarean section pain control. Materials and Methods: This study was a double blind clinical trial. It arranged for 240 parturients who scheduled for emergency cesarean section with pain after surgery in spite of spinal anesthesia. All patients were in ASA class I. They were divided randomly in two groups .Meperidine (M) and Tramadol (T) groups with 120 patients in each group. After beginning of pain in post anesthesia care unit (VAS> or = 4), in group (T) tramadol 1.5 mg/kg and in group (M) meperidine  .5 mg/kg were injected intravenously. Apart from pain, other drug complications such as shivering, blood pressure changes, itching, nausea and vomiting, drowsiness were recorded one and two hours after injection. Data were analyzed by chi-square test. Results: Relative frequency rate (RFR) of 50% decrease in pain score one hour after intravenous injection was 56.7% in group (T) and 69.2% in group (M) ( P = 0.054). RFR for respiratory depression after one hour was 5.8% in (M) group and 0 in (T) group (P = 0.007). RFR for nausea after one hour was 39.2% in (T) group and 23.3% in (M) group (P = 0.008). RFR for vomiting after one hour was 23.3% in (T) group and 13.3% in (M) group (P= 0.045). RFR for drowsiness after one hour was 25% in (M) group and 3.3% in (T) group (P=0.007). There was no statistically significant relationship after 2nd hour for pain relief, nausea, vomiting and drowsiness between two groups. There was no difference between two groups in RFR for shivering, blood pressurechanges and itching in both two groups. Conclusion: This study illustrates both remedies Meperidine and Tramadol which were effective for pain relief and shivering after cesarean section. But according to high incidence of nausea and vomiting with Tramadol and more analgesic effects of Meperidine than Tramadol, administration of Meperidine is better than Tramadol after cesarean section for pain control.

Objective:  The aim of conducting this study was to evaluate the outcome of a Micro vascular Decompression procedure for the definitive treatment of Trigeminal Neuralgia in our setup. Material and Methods:  This observational prospective study was carried out in Neurosurgery unit Hayatabad Medical Complex, Peshawar. A total of 50 patients operated for micro vascular decompression surgeries were enrolled in the study, both genders and any age were in inclusion criteria. Patients previously operated for trigeminal neuralgia were excluded from the study. Post operatively all patients were followed for 1year to calculate the outcome in terms of pain control using visual analogue score (VAS). Immediate pain relief during the first post-operative week and trigeminal neuralgia pain at 1 year post op were recorded and  graded into three categories based on Visual Analogue Scale (VAS) such as Excellent: 0-2 , Good: 3-6, Fail/Poor: 7 – 10. Results:  50 patients fulfilled the inclusion criteria. 22 were male & 28 were female with an age range from 42-78 years. Average duration of disease was 5 years. In 30 patients, clinically v2-v3 were predominantly involved, in remaining 14 patient v1-v2 were involved & only in 6 patients all three branches were involved. Among all operated 50 patients 18(36%) had excellent pain relief, 26 (52%) had good pain relief & 6 (12%) had fail/poor pain relief. Conclusion:  From this data it was concluded that micro vascular decompression is an effective surgical procedure in relieving pain of trigeminal neuralgia in patients who are refractive to medical treatment.
