Rest pain, ulceration, and gangrene are often considered together in studies describing outcomes in patients with critical limb ischemia. A retrospective analysis of prospectively collected data of 152 infrainguinal bypass grafts performed on 128 patients with chronic critical limb ischemia over a 6-year period was carried out. Grafts were classified according to the mode of presentation and were followed up by regular clinical and duplex examinations. Mean follow-up period was 29 months (range 12 to 60 months). Patients' demographics, risk factors, and graft characteristics were not statistically different between the groups. The 5-year cumulative primary patency rates were 33%, 52%, and 51% for gangrene, ulceration, and rest pain, respectively (p = 0.04). The 5-year cumulative primary assisted patency rates were 46%, 70%, and 72% for gangrene, ulceration, and rest pain, respectively (p = 0.01). The 5-year cumulative secondary patency rates were 48%, 76%, and 75% for gangrene, ulceration, and rest pain, respectively (p = 0.003). The 5-year cumulative limb salvage rates were 59%, 87%, and 83%, for gangrene, ulceration, and rest pain, respectively (p = 0.01). Gangrene is a distinct subcategory of critical limb ischemia with a worse prognosis than ulceration and rest pain and should be classified as such when reporting results of infrainguinal bypass grafts.

Untreated pain is a major health care issue and very little is known about the treatment of pain and the effect of pain on post-operative outcomes in older adults. This study was performed to identify the impact of pain on outcomes following hip fracture in older adults. Four hundred and eleven consecutive cognitively intact patients admitted with hip fracture to four New York hospitals were enrolled in a prospective cohort study. Patients were interviewed daily using standardized pain assessments. We used multiple logistic regression and ordinary least squares linear regression to examine the association of post-operative pain on immediate post-operative outcomes (duration of stay, physical therapy sessions missed or shortened, ambulation following surgery, and post-operative complications) and outcomes 6 months following fracture (locomotion, mortality, return to the community, residual pain). Patients with higher pain scores at rest had significantly longer hospital lengths of stay (P=0.03), were significantly more likely to have physical therapy sessions missed or shortened (P=0.002), were significantly less likely to be ambulating by post-operative day 3 (P<0.001), took significantly longer to ambulate past a bedside chair (P=0.01), and had significantly lower locomotion scores at 6 months (P=0.02). Pain at rest was not significantly associated with post-operative complications, nursing home placement, survival at 6 months, or residual pain at 6 months. Post-operative pain is associated with increased hospital length of stay, delayed ambulation, and long-term functional impairment. Whereas appropriate caution is warranted in administering opioid analgesics to older adults, these data suggest that improved pain control may decrease length of stay, enhance functional recovery, and improve long-term functional outcomes.

Ketamine oral rinse provided effective palliation of intractable mucositis pain in a 32-year-old woman with squamous carcinoma of the tongue undergoing radiation therapy. Pain at rest and with eating decreased with ketamine, allowing for a tapering of her opiate dose. No side effects of ketamine were reported. Treatment benefits most likely arose from the inhibition by ketamine of peripheral N-methyl D-aspartate receptors, though other mechanisms of action may have been contributory. Further evaluation of topical ketamine in the treatment of mucositis-related pain, and, potentially, other causes of inflammatory oral pain, are warranted.

When peripheral arteriosclerosis progresses to the stage where blood flow through both primary and collateral circulations is impaired seriously, arteriolar relaxants, physical therapeutic, pharmacological and surgical, may aggravate the nutritional deficit. Although tissue viability is maintained precariously, limited activity may be tolerated unless the delicate balance between blood supply and metabolic activity is upset by the vicious circle of rest pain and dependent edema. This vicious circle constitutes an immediate threat to the structural integrity of the limb. Rest pain must be controlled if the delicate balance between blood supply and metabolic activity is to be restored and the threat of amputation mitigated. Intravenous injections of procaine may be of value.

We investigated efficacy and safety of implantation of autologous bone marrow mononuclear cells plus platelets, including endothelial progenitor cells (EPCs), for recovering refractory chronic peripheral arterial disease (PAD) using visual and quantitative analyses by 99mTc-tetrofosmin (TF) perfusion scintigraphy, and also investigated various quantitative assessments objectively. We performed 12 consecutive cases and 19 limbs and hands with severe chronic PAD that were almost Fontaine class IV (11/12 cases, about 92%) in this trial. This treatment was very effective in relieving severe pain of PAD, especially for Buerger's disease. We used a visual analog scale (VAS) for measurement of pain level. The maximum pain level before implantation was 66.5+/-5.0 mm, and it decreased to 12.1+/-2.2 mm after implantation (p < 0.001). Rest pain in legs and fingers was resolved in 11 cases (11/12 cases, 92%). All patients could measure pain-free walking time on a treadmill, which improved remarkably (140+/-53 s before implantation vs. 451+/-74 s after implantation, p = 0.034). Resting ankle brachial pressure index (ABI) in legs implanted with bone marrow mononuclear cells was also improved (0.65+/-0.08 before implantation vs. 0.73+/-0.07 after implantation, p = 0.055). According to 99mTc-TF perfusion scintigraphy, the proximal area (region from knee to ankle) was 1.32+/-0.10 before implantation versus 1.56+/-0.11 after implantation (p = 0.007). 99Tc-TF perfusion scintigraphy in the distal area (region from ankle to end of toes, or from wrist to end of fingers) was 0.79+/-0.06 before implantation versus 0.83+/-0.06 after implantation (p = 0.29). Ischemic legs and hands that were injected showed increased perfusion blood flow. 99mTc-TF perfusion scintigraphy was effective to estimate visual and quantitative analysis of collateral vessels in neovascularization. We were successful with this new treatment for the most severe, chronic PAD that was not curable by any of the current treatments. Thus, this therapeutic angiogenesis could be a new strategy for saving severe ischemic limbs and hands.

Vertebral collapse is one of the most common fractures associated with osteoporosis. The subsequent back pain is severe and often requires medications, bed rest and hospitalization to control pain and improve mobilization. The purpose of this systematic review was to assess the effects of calcitonin versus placebo for the treatment of acute pain in patients sustaining stable, recent, osteoporotic vertebral compression fractures. MEDLINE (1966-2003), EMBASE (1980-2003), Cochrane Controlled Trial Registry (2003, volume 3), other databases, and conference proceedings were searched for relevant research. Primary study authors and the pharmaceutical manufacturer were contacted, and bibliographies of relevant papers were hand-searched. Randomized, double-blind, placebo-controlled trials comparing calcitonin versus placebo for the acute pain of recent osteoporotic vertebral compression fractures were included. Two reviewers extracted data, performed numeric calculations and extrapolated graphical data independently. The combined results from five randomized controlled trials, involving 246 patients, determined that calcitonin significantly reduced the severity of pain using a visual analogue scale following diagnosis. Pain at rest was reduced as early as 1 week into treatment (weighted mean difference [WMD] =3.08; 95% confidence interval [CI]: 2.64, 3.52) and this effect continued weekly to 4 weeks (WMD =4.03; 95% CI: 3.70, 4.35). A similar pattern was seen for pain scores associated with sitting, standing, and walking. Side effects were gastrointestinal, minor and often self-limited. Calcitonin appears to be effective in the management of acute pain associated with acute osteoporotic vertebral compression fractures by shortening time to mobilization.

Synergism between gabapentin and morphine in treating incisional pain has been demonstrated in animal experiments and clinical studies. The efficacy of gabapentin for treatment of perioperative pain remains controversial. This study was designed to detect the influence of gabapentin premedication on morphine consumption in the immediate postoperative period in patients undergoing lumbar laminectomy and discectomy. Either gabapentin 800 mg (in two equally divided doses) or placebo was given preoperatively to 60 adult patients undergoing elective lumbar laminectomy or discectomy in a double-blinded, placebo-controlled, randomized study. Standard general anesthesia was given to all the patients. Morphine was administered via patient-controlled analgesia pump in the immediate postoperative period for first 8 hours. Pain at rest and on movement was assessed using a Verbal Rating Scale (VRS) every 2 hours for the first 8 postoperative hours. There were no differences in demographics or surgical duration between the two groups. The amount of fentanyl administered in the intraoperative period was similar between the two groups. In the postoperative period, the VRS score for pain at 0, 2, 4, 6, and 8 hours was not significantly different between the two groups. Highest median VRS score was recorded at 0 hours postoperatively in both groups (VRS: rest = 6, movement = 8 in placebo group; rest = 6, movement = 8 in gabapentin group). Total morphine consumption and side effects were similar in the two groups. Gabapentin does not decrease the morphine requirement or morphine side effects in the immediate postoperative period following lumbar laminectomy and discectomy.

There is no information concerning the association of ropivacaine and clonidine for ilioinguinal-iliohypogastric block. In this prospective, double-blind study, we randomly assigned 40 adult patients scheduled for inguinal herniorrhaphy under monitored anesthesia care to receive either 225 mg ropivacaine (7.5 mg/mL) alone (control group) or combined with 75 mug clonidine (clonidine group) for preoperative ilioinguinal-iliohypogastric block. After completion of surgery, patients were transferred to the postanesthesia care unit and were asked to stand up and walk around at the second postoperative hour. After leaving the postanesthesia care unit, patients could take oral propacetamol (500 mg) and codeine (30 mg) on request. Pain intensity was assessed with a 100 mm visual analog scale. Time to first request of supplemental analgesics (median [95% confidence interval]) was 10 h (7.1-14.5 h) and 9 h (6.4->24 h) respectively in the clonidine and control groups (P = 0.83). Pain at rest did not differ between groups whereas pain at motion was reduced on the third postoperative day in the clonidine group. More patients who received clonidine experienced orthostatic hypotension upon standing up within the first postoperative hours (6 of 20 versus 1 of 20 in the control group; P < 0.05). In conclusion, the benefit of adding clonidine 75 mug to ropivacaine for ilioinguinal-iliohypogastric block for motion pain on the third postoperative day must be balanced with an increasing risk of orthostatic hypotension in the immediate postoperative period.

Although nonsteroidal antiinflammatory drugs (NSAIDs) improve postoperative pain relief after cesarean delivery, they carry potential side effects (e.g., bleeding). Perioperative cyclooxygenase (COX)-2 inhibitors show similar analgesic efficacy to nonsteroidal antiinflammatory drugs in many surgical models but have not been studied after cesarean delivery. We designed this randomized double-blind study to determine the analgesic efficacy and opioid-sparing effects of valdecoxib after cesarean delivery. Healthy patients undergoing elective cesarean delivery under spinal anesthesia were randomized to receive oral valdecoxib 20 mg or placebo every 12 h for 72 h postoperatively. As a result of cyclooxygenase-2 inhibitors safety concerns that became apparent during this study, the study was terminated early after evaluating 48 patients. We found no differences in total analgesic consumption between the valdecoxib and placebo groups (121 +/- 70 versus 143 +/- 77 morphine mg-equivalents, respectively; P = 0.26). Pain at rest and during activity were similar between the groups despite adequate post hoc power to have detected a clinically significant difference. There were also no differences in IV morphine requirements, time to first analgesic request, patient satisfaction, side effects, breast-feeding success, or functional activity. Postoperative pain was generally well controlled. Adding valdecoxib after cesarean delivery under spinal anesthesia with intrathecal morphine is not supported at this time.

Complex regional pain syndrome type I is a disorder of the extremities with disability and pain as the most prominent features. This paper describes the results of cognitive behavioural therapy combined with mirror box therapy in three patients with chronic complex regional pain syndrome type I. Before, during and at follow-up the following measurements were assessed: pain (visual analogue scale, 0-100), range of motion, muscle strength, and the areas of allodynia and of hyperalgesia. Furthermore, patients were asked for their feelings and thoughts about mirror box therapy and about the affected limb. Pain at rest, pain after measuring allodynia/hyperalgesia and pain after measuring strength decreased. Range of motion improved in two patients. Strength improved in one patient. The area of hyperalgesia increased for all three patients, whereas the area of allodynia remained stable in two patients and decreased in one patient. Two patients felt that their affected limb still belonged to them, one did not. Cognitive behavioural therapy combined with mirror box therapy for patients with chronic complex regional pain syndrome type I may facilitate rehabilitation. Measuring whether the affected limb still belongs in the patient's body scheme could be of prognostic value in the treatment of chronic complex regional pain syndrome type I patients.
