RESUMEN
PURPOSE: To report a case of early postoperative scleral buckle slippage because of the dehiscence of scleral belt loop tunnels. METHOD: Case report. RESULTS: A 54-year-old woman presented with painful diplopia after a combination pars plana vitrectomy and scleral buckling procedure. Ocular movements were limited. Forced duction testing was restricted in all directions. Anterior slippage of the silicone band was suggested on computed tomography (CT) scans and was confirmed with surgical exploration. During surgery, it was found that thin-roofed scleral belt loop tunnels were dehisced in three quadrants leading to anterior slippage of the buckle. The displaced buckle was removed. Diplopia and pain resolved, and ocular motility improved immediately afterward. The retina remained attached at six months follow-up. A supplemental video summarizes the surgical findings and postoperative results. CONCLUSION: Spontaneous dehiscence of scleral belt loops may occur in thinly dissected scleral tunnels. Painful eye movement, diplopia, and a positive forced duction test should raise suspicion about a displaced scleral buckle. A CT scan may help with the diagnosis. Early diagnosis and immediate surgical intervention are needed to minimize patient discomfort and to improve long-term ocular motility.

SPECIFIC CLINICAL ISSUE: The purpose of this clinical consultation is to offer nurses evidence-based strategies to provide holistic care to their patients with comorbid depression and pain. The combination of depression and pain is common and, if not managed effectively, has negative outcomes. Treatment-resistance is one negative outcome. The worst-case scenario for unrelieved depression and/or pain is suicide. MAJOR PRACTICE RECOMMENDATIONS BASED ON BEST EVIDENCE: Antidepressants, particularly duloxetine, have had efficacy for pain and depression. Cognitive behavioral therapy, an evidence-based treatment for depression, has been found to decrease pain. Examples of additional interventions include exercise, relaxation techniques, mindfulness, and music. Providing holistic nursing care and working with other disciplines optimizes more effective management of these co-occurring conditions.

AIM: Limb amputation traumatically alters body image. Sensations rapidly prevail that the limb is still present and 85% of patients portray phantom limb pain. Throughout the testimonies of amputated patients with intense phantom limb pain, we show the difficulty in treating this chronic pain with current pharmacological and nonpharmacological therapies. PATIENTS & METHODS: We qualitatively analyzed the therapeutic choices of five amputees, the effectiveness of the treatments chosen and the impact on patients' quality-of-life. RESULTS & CONCLUSION: In general, patients who are refractory to pharmacological treatments are in favor of trying alternative therapies. It is therefore crucial to design a combined and personalized therapeutic plan under the coordination of a multidisciplinary team for the wellbeing of the patient.

Nonpharmacologic interventions for symptom management in patients with rheumatoid arthritis are underinvestigated. Limited data suggest that aromatherapy massage and reflexology may help to reduce pain and fatigue in patients with rheumatoid arthritis. The aim of this study was to examine and compare the effects of aromatherapy massage and reflexology on pain and fatigue in patients with rheumatoid arthritis. The study sample was randomly assigned to either an aromatherapy massage (n = 17), reflexology (n = 17) or the control group (n = 17). Aromatherapy massage was applied to both knees of subjects in the first intervention group for 30 minutes. Reflexology was administered to both feet of subjects in the second intervention group for 40 minutes during weekly home visits. Control group subjects received no intervention. Fifty-one subjects with rheumatoid arthritis were recruited from a university hospital rheumatology clinic in Turkey between July 2014 and January 2015 for this randomized controlled trial. Data were collected by personal information form, DAS28 index, Visual Analog Scale and Fatigue Severity Scale. Pain and fatigue scores were measured at baseline and within an hour after each intervention for 6 weeks. Pain and fatigue scores significantly decreased in the aromatherapy massage and reflexology groups compared with the control group (p < .05). The reflexology intervention started to decrease mean pain and fatigue scores earlier than aromatherapy massage (week 1 vs week 2 for pain, week 1 vs week 4 for fatigue) (p < .05). Aromatherapy massage and reflexology are simple and effective nonpharmacologic nursing interventions that can be used to help manage pain and fatigue in patients with rheumatoid arthritis.

OBJECT: Spinal cord stimulation (SCS) is a well-known treatment option for intractable neuropathic pain after spinal surgery, but its pathophysiological mechanisms are poorly stated. The goal of this study is to analyse the feasibility of using brain MRI, functional MRI (fMRI) and Magnetic Resonance Spectroscopy (MRS) as tools to analyse these mechanisms in patients with externalised neurostimulators during trial period. METHODS: The authors conducted in an in vitro and in vivo study analysing safety issues when performing brain MRI, fMRI and MRS investigations in human subjects with externalised SCS. Temperature measurements in vitro were performed simulating SCS during MRI sequences using head transmit-receive coils in 1.5 and 3 T MRI systems. 40 Patients with externalised SCS were included in the in vivo study. 20 patients underwent brain MRI, fMRI and another 20 patients underwent brain MRI and MRS. RESULTS: A maximal temperature increase of 0.2°C was measured and neither electrode displacements nor hardware failures were observed. None of the patients undergoing the MRS sequences at the 1.5 or 3 T MRI scanners described any discomfort or unusual sensations. CONCLUSION: We can conclude that brain MRI, fMRI and MRS studies performed in patients with externalised SCS can be safely executed.

OBJECTIVES: Chronic pain is a common disabling illness that does not completely respond to current medical treatments. As a consequence, in recent years many alternative interventions have been suggested. Among them, mindfulness-based interventions (MBIs) are receiving growing attention. The aim of the present article is to review controlled studies investigating the efficacy of MBIs for the reduction of pain and the improvement of depressive symptoms in patients suffering from chronic pain. METHODS: A literature search was undertaken using MEDLINE,(®) ISI web of knowledge, the Cochrane database, and references of retrieved articles. The search included articles written in English published up to July 2009. The data were independently extracted by two reviewers from the original reports. Quality of included trials was also assessed. RESULTS: Ten (10) studies were considered eligible for the present review. Current studies showed that MBIs could have nonspecific effects for the reduction of pain symptoms and the improvement of depressive symptoms in patients with chronic pain, while there is only limited evidence suggesting specific effects of such interventions. Further findings evidenced some improvements in psychologic measures related to chronic pain such as copying with pain following MBIs as well. DISCUSSION: There is not yet sufficient evidence to determine the magnitude of the effects of MBIs for patients with chronic pain. Main limitations of reviewed studies include small sample size, absence of randomization, the use of a waiting list control group that does not allow distinguishing of specific from nonspecific effects of MBI as well as differences among interventions. CONCLUSIONS: However, because of these preliminary results, further research in larger properly powered and better designed studies is warranted.

UNLABELLED: We investigated changes in visual cortex excitability by analyzing visual evoked potential (VEP) habituation in healthy subjects during tonic pain evoked by the cold-pressor test (CPT). We tested VEP amplitude habituation (slope of the linear regression line for N1-P1 amplitude from the 1st to 6th block of 100 sweeps) in 19 healthy volunteers during 4 experimental conditions: baseline; no-pain (hand held in warm water, 25 degrees C); pain (hand held in cold water, 2-4 degrees C); and the after-effects of tonic pain. During baseline and no-pain sessions, VEPs habituated normally across the 6 consecutive blocks (mean slope -.28 and -.18%), whereas during pain and its after-effects they failed to decrease (0%, and -.11%). Tonic pain induced by the CPT abolishes normal VEP habituation and the lack of habituation persists after the CPT is stopped. Tonic pain probably abolishes VEP habituation by acting on brainstem neural structures which modulate thalamo-cortical activation thereby changing visual cortex excitability. PERSPECTIVE: This study shows that tonic pain alters visual cortex excitability, a brain region unrelated to pain processing. These changes probably reflect defensive strategies against pain. Extending the study from healthy volunteers to patients with migraine between attacks would offer the opportunity to investigate visual cortical excitability under conditions when baseline habituation is absent.

Despite management with opioids and other pain modifying therapies, neuropathic pain continues to reduce the quality of life and daily functioning in HIV-infected individuals. Cannabinoid receptors in the central and peripheral nervous systems have been shown to modulate pain perception. We conducted a clinical trial to assess the impact of smoked cannabis on neuropathic pain in HIV. This was a phase II, double-blind, placebo-controlled, crossover trial of analgesia with smoked cannabis in HIV-associated distal sensory predominant polyneuropathy (DSPN). Eligible subjects had neuropathic pain refractory to at least two previous analgesic classes; they continued on their prestudy analgesic regimens throughout the trial. Regulatory considerations dictated that subjects smoke under direct observation in a hospital setting. Treatments were placebo and active cannabis ranging in potency between 1 and 8% Delta-9-tetrahydrocannabinol, four times daily for 5 consecutive days during each of 2 treatment weeks, separated by a 2-week washout. The primary outcome was change in pain intensity as measured by the Descriptor Differential Scale (DDS) from a pretreatment baseline to the end of each treatment week. Secondary measures included assessments of mood and daily functioning. Of 127 volunteers screened, 34 eligible subjects enrolled and 28 completed both cannabis and placebo treatments. Among the completers, pain relief was greater with cannabis than placebo (median difference in DDS pain intensity change, 3.3 points, effect size=0.60; p=0.016). The proportions of subjects achieving at least 30% pain relief with cannabis versus placebo were 0.46 (95%CI 0.28, 0.65) and 0.18 (0.03, 0.32). Mood and daily functioning improved to a similar extent during both treatment periods. Although most side effects were mild and self-limited, two subjects experienced treatment-limiting toxicities. Smoked cannabis was generally well tolerated and effective when added to concomitant analgesic therapy in patients with medically refractory pain due to HIV DSPN.

UNLABELLED: Little is known about cognitive and behavioral factors that influence older adults' adjustment to chronic pain. The objective of this study was to investigate the relationship of self-efficacy for managing pain to reports of pain intensity, pain-related disability, depressive symptoms, and pain coping strategy use among 140 retirement community residents (88% female; age mean = 81.7, range 66-99 years) with chronic pain. The 8-item Arthritis Self-Efficacy Scale, modified to specify pain rather than arthritis, demonstrated good psychometric characteristics (Cronbach alpha = .89, minimal floor and ceiling effects, and validity) in this sample. Controlling for age, gender, and pain intensity, self-efficacy was associated significantly and negatively with pain-related disability and depressive symptoms (P values < .001), and positively with use of pain coping strategies previously found to be associated with better outcomes (task persistence, exercise/stretch, coping self-statements, activity pacing; P values < .05). Self-efficacy for managing pain appears to be important in the adjustment of older adults with pain. Research is needed to determine whether interventions designed to increase self-efficacy improve quality of life and prevent functional declines in this population. PERSPECTIVE: Among retirement community residents (mean age of 82 years) with chronic pain, higher self-efficacy for managing pain is associated with less disability and depression and with the use of pain coping strategies related to better adjustment. This suggests the potential value of interventions to increase self-efficacy in this population.

OBJECTIVE: The authors hypothesized that central factors may underlie sensory deficits in patients with nondermatomal somatosensory deficits (NDSD) and that functional brain imaging would reveal altered responses in supraspinal nuclei. BACKGROUND: Patients with chronic pain frequently present with NDSD, ranging from hypoesthesia to complete anesthesia in the absence of substantial pathology and often in association with motor weakness and occasional paralysis. Patients with pain and such pseudoneurologic symptoms can be classified as having both a pain disorder and a conversion disorder (Diagnostic and Statistical Manual of Mental Disorders-IV classification). METHODS: The authors tested their hypothesis with functional MRI (fMRI) of brush and noxious stimulation-evoked brain responses in four patients with chronic pain and NDSD. RESULTS: The fMRI findings revealed altered somatosensory-evoked responses in specific forebrain areas. Unperceived stimuli failed to activate areas that were activated with perceived touch and pain: notably, the thalamus, posterior region of the anterior cingulate cortex (ACC), and Brodmann area 44/45. Furthermore, unperceived stimuli were associated with deactivations in primary and secondary somatosensory cortex (S1, S2), posterior parietal cortex, and prefrontal cortex. Finally, unperceived (but not perceived) stimuli activated the rostral ACC. CONCLUSIONS: Diminished perception of innocuous and noxious stimuli is associated with altered activity in many parts of the somatosensory pathway or other supraspinal areas. The cortical findings indicate a neurobiological component for at least part of the symptoms in patients presenting with nondermatomal somatosensory deficits.

OBJECTIVE: In this study twenty-four women with pain accounted for by psychological factors (DSM-IV, 307.80) and twenty-four with major depression diagnosed according to DSM-III-R were compared to study the relationship between pain and depression. METHOD: They were examined by a semi-structured, tape-recorded interview to study their childhood experiences and adult behavior. The interviews were rated by two independent and blind raters. Interrater correlation (Cohen-Kappa) varied between good and close agreement. RESULTS: Of childhood experiences, "brutality between parents," "brutality toward child," and "sexual abuse" were often found in both groups and were more strongly represented in these than in comparison groups of former studies. As adults, the pain group had experienced more serious illness (p = 0.037) and surgery (p = 0.014). The depression group more often had a history of depression (15/24 vs. 4/24; p = 0.001). The pain group spoke negatively of its physicians (p = 0.001), was more hostile during the interview (p = 0.041), was less convinced of the benefit of the hospital stay (p = 0.029), felt less self-responsible, and was more pessimistic (p = 0.013). The pain patients also provoked negative emotions in the raters, whereas the latter's reaction to the depression group was compassion and interest (p = 0.0005) (Pearson's chi2 and Fisher's exact tests). CONCLUSIONS: The results show that negative childhood experiences are prominent and similar in patients with pain accounted for by psychological factors and in patients after major depression. Adult behavior, however, is very different.

AIM: To test the therapeutic efficacy of octreotide administered subcutaneously for the relief of chronic refractory epigastric pain severe enough to provoke nutritional impairment. SUBJECTS AND METHODS: Seventeen patients were enrolled in an open trial. Epigastric pain had lasted from 1 to 8 years (median: 5 years), following anti-reflux surgery in eight patients. Median weight loss was 10% (range 10-15). The initial dose of octreotide was 50 microgram b.d, adjusted during the follow-up visits which were scheduled for months 1, 3, 6, 8, 10, 12 and every 3 months. At each visit, overall symptomatic improvement, frequency and intensity of symptoms were checked on a 10-cm visual analogic scale. RESULTS: At month 1, a progressive improvement of pain intensity was reported in 15 of the 17 patients, while octreotide was a therapeutic failure in two. In four out of 15, the daily dose of octreotide was increased to 100 microgram b.d. In these 15 patients, median follow-up was 7 months (3-27). The symptomatic benefit was maintained in each patient at month 3, with a median weight gain of 3.5 kg.2-5 An attempt to stop octreotide led to recurrence of symptoms in 2-3 days which were as intense as before the treatment. The 11 patients followed-up for at least 6 months reported persistent improvement of symptoms with octreotide and a median weight gain of 4 kg.3-7 Four patients were followed up for more 11-27 months: octreotide was withdrawn gradually in two who remained asymptomatic. Six of the 17 patients experienced minor side-effects, but none developed biliary sludge. CONCLUSIONS: This open study suggests that octreotide could be a promising alternative treatment when all others fail in refractory chronic functional epigastric pain severe enough to limit food intake and to induce nutritional impairment. These results must be tested by a placebo-controlled study.

Our experience in treating 10 patients with intractable pain with paraplegia employing percutaneous epidural or dorsal column stimulation is presented. Initial and long-term results in this group are contrasted with those of 9 patients with intractable post-amputation or post-traumatic neuroma pain. The successful results of neurostimulation treatment of peripheral nerve pain contasts with the disappointing results in the treatment of paraplegic pain.
