Various surgical approaches have been proposed for the treatment of thoracic outlet syndrome (TOS). The authors of this study focused on the differences in outcome after supraclavicular neuroplasty of brachial plexus (SNBP [no rib resection]) and transaxillary first rib resection (TFRR) in patients in whom the dominant clinical problem was pain.
                Fifty-five patients were randomized to undergo TFRR or SNBP. Patients with an anomalous cervical rib, intrinsic weakness, and primarily vascular findings were excluded from the study. Preoperatively, the following findings were typically observed: provocation of symptoms by certain postures (the so-called spear-throwing position as well as downward tugging of the shoulder) and marked tenderness in the supraclavicular fossa. The intergroup severity of the symptoms was comparable. Eight patients were lost to follow up. There were 24 TFRRs (in two cases the procedure was bilateral) and 25 SNBPs. The mean follow-up interval was 37 months. In both groups pain decreased significantly after surgery. By all measures the TFRR operation conferred superior results. Patients reported significantly less pain (39 +/- 7 compared with 61 +/- 7; score range 0-100 on a visual analog scale), greater percentage of pain relief (52 +/- 8% compared with 30 +/- 7%), and less pain (3.7 +/- 0.4 compared with 5.1 +/- 0.5) on an affective scale (all p < 0.05) in the TFRR and SNBP groups, respectively). In the TFRR group, 75% of patients reported good or excellent outcomes compared with 48% in the SNBP group (p < 0.05).
                Transaxillary first rib resection provided better relief of symptoms than SNBP. The major compressive element in patients with TOS-associated pain appeared to be the first rib. To test the usefulness of tailoring cognitive-behavioral therapy (CBT) for patients with temporomandibular disorders (TMD) who demonstrated poor psychosocial adaptation to their TMD condition, independent of physical diagnosis.
                A randomized clinical trial compared a 6-session CBT intervention delivered in conjunction with the usual TMD treatment to the usual conservative treatment by TMD specialist dentists. For study inclusion, Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), Axis II criteria, were used to target patients with elevated levels of TMD pain-related interference with daily activities, independent of physical diagnosis (i.e., Axis I).
                At the post-treatment assessment, about 4 months after the baseline evaluations, the comprehensive care group, when compared to the usual treatment group, showed significantly lower levels of characteristic pain intensity, significantly higher self-reported ability to control their TMD pain, and a strong trend (P = .07) toward lower pain-related interference in daily activities. From post-intervention to 1-year follow-up, all subjects showed improvement. At the 1-year follow-up, the comprehensive care group, while not losing any of its early gains, was not significantly different from the usual care group with regard to reported levels of pain, ability to control pain, and levels of interference in activities. For many of these psychosocially disabled TMD patients, pain and interference 1 year after treatment remained at the same or higher levels than those observed at baseline among a group of patients selected for a separate randomized clinical trial on the basis of better psychosocial adaptation.
                The 6-session CBT intervention for patients with heightened psychologic and psychosocial disability was effective in improving pain-related variables over the course of the CBT in conjunction with usual treatment, but was too brief an intervention to result in further improvement after the sessions ended. Patient ratings of treatment satisfaction and helfulness were high for both groups, but they were significantly higher for the comprehensive care group. Few non-surgical conditions are more painful than rib fractures. There are a few methods for pain relief in patients with minor rib fractures.
                We used a non-steroidal anti-inflammatory drug (NSAID, Naproxen sodium) and transcutaneous electrical nerve stimulator (TENS) to control pain of the patients with uncomplicated minor rib fractures. One hundred consecutive patients admitted to Kartal Education and Research Hospital Emergency Service, were randomized into four groups. The patients were assigned to one of the following pain treatments: NSAID, TENS, NSAID plus inactive TENS or placebo. The patients used NSAIDs and placebo four times a day and TENS twice a day for 3 days. All patients were asked to assess their pain level with a scoring system on days 0, 1 and 3.
                The most effective treatment was TENS on days 1 and 3 (P<0.05). Although NSAID and NSAID plus inactive TENS controlled pain better than placebo on day 1 (P<0.05), this superiority did not continue to day 3 (P>0.05). There was no difference between NSAID and NSAID plus inactive TENS in controlling pain on either days 1 or 3.
                We conclude that TENS was more effective than NSAID or placebo in patients with uncomplicated minor rib fractures, because of its prominent and admirable efficacy in reduction of pain. This multi-institutional Phase III randomized study compared 10 Gy single-fraction radiotherapy (RT) with 20 Gy in five fractions in the palliation of thoracic symptoms from lung cancer.
                The primary end point was palliation of thoracic symptoms at 1 month after RT, evaluated by a patient-completed daily diary card. Secondary end points included quality of life, toxicity, and survival.
                Most (69%) of 230 patients randomized had locally advanced disease unsuitable for curative treatment. The treatment arms were well balanced with respect to the known prognostic factors. At 1 month after RT, no difference was found in symptom control between the two arms, as judged by the daily diary scores. The changes in the scores on the Lung Cancer Symptom Scale indicated that the fractionated RT (five fractions) group had greater improvement in symptoms related to lung cancer (p = 0.009), pain (p = 0.0008), ability to carry out normal activities (p = 0.037), and better global quality of life (p = 0.039). The European Organization for Research and Treatment of Cancer QLQ-C30 scores showed that patients receiving five fractions had a greater improvement in scores with respect to pain (p = 0.04). No significant difference was found in treatment-related toxicity. Patients who received five fractions survived on average 2 months longer (p = 0.0305) than patients who received one fraction.
                Although the two treatment strategies provided a similar degree of palliation of thoracic symptoms, the difference in survival between the two study arms was of a clinically relevant magnitude. Forty-two patients with subacromial impingement syndrome entered a randomized prospective study comparing open anterior acromioplasty with a physiotherapy regime. The criterion for a successful outcome of treatment was a reduction of the initial pain score of more than 50% using the visual analogue scale (VAS) technique. The evaluation was performed by an independent observer. At the 6-month follow-up, treatment in the surgical group had been successful in 12/21 (57%) patients versus 6/18 (33%) in the physiotherapy group. A one-year evaluation revealed 16/21 (76%) "successes" in the surgical group. A direct and unbiased comparison with the physiotherapy group was not possible at one year, since 13 patients chose surgery after initial physiotherapy. However, in "an intention to treat" analysis outcome at one year was significantly better in those randomized to surgery. We found two standardized, composite, active movements--the "Pour out of a Pot" manoeuvre requiring the emptying of a pot of water, and the "Hand in Neck" manoeuvre--to be of predictive value for the outcome of surgery. When combining three pain-related variables into a criterion for prediction of success, a sensitivity of 78% (p < 0.02) and a specificity of 90% (p < 0.03) were attained. We advance the hypothesis that pain in the impingement syndrome is mainly elicited by comparison of the subacromial bursa. In some patients a traction-responsive pain generator in the supraspinatus tendon may be present as well. The attempt to further reduce operative trauma in laparoscopic cholecystectomy has led to new techniques such as natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SILS). These new techniques are considered to be painless procedures, but no published studies investigate the possibility of different pain scores in these new techniques versus classic laparoscopic cholecystectomy. In this randomized control study, we investigated pain scores in SILS cholecystectomy versus classic laparoscopic cholecystectomy.
                Forty patients (34 women and 6 men) were randomly assigned to two groups. In group A (n = 20) four-port classic laparoscopic cholecystectomy was performed. Patients in group B (n = 20) underwent SILS cholecystectomy. In all patients, preincisional local infiltration of ropivacaine around the trocar wounds was performed. Infusion of ropivacaine solution in the right subdiaphragmatic area at the beginning of the procedure plus normal saline infusion in the same area at the end of the procedure was performed in all patients as well. Shoulder tip and abdominal pain were registered at 2, 6, 12, 24, 48, and 72 h postoperatively using visual analog scale (VAS).
                Significantly lower pain scores were observed in the SILS group versus the classic laparoscopic cholecystectomy group after the first 12 h for abdominal pain, and after the first 6 h for shoulder pain. Total pain after the first 24 h was nonexistent in the SILS group. Also, requests for analgesics were significantly less in the SILS group, while no difference was observed in incidence of nausea and vomiting between the two groups.
                SILS cholecystectomy, as well as the invisible scar, has significantly lower abdominal and shoulder pain scores, especially after the first 24 h postoperatively, when this pain is nonexistent. (Registration Clinical Trial number: NTC00872287, www.clinicaltrials.gov ). To investigate whether the combination of standard medical care (SMC) and short-term cognitive-behavioral family treatment (CBT) in the treatment of recurrent abdominal pain (RAP) was more effective than SMC alone.
                Children recently diagnosed with RAP via physician examination were randomized into SMC (n = 29) and SMC plus CBT (n = 40) groups. Outcome measures included multiple dimensions of child and parent reported child pain, somatization, and functional disability, and school absences and physician contacts.
                Children and parents participating in the combined SMC + CBT intervention reported significantly less child and parent reported child abdominal pain than children in the SMC intervention immediately following the intervention and up to 1 year following study entry, as well as significantly fewer school absences. Significant differences in functional disability and somatization were not revealed.
                These results, in combination with previous studies, add support to the effectiveness of CBT intervention in reducing the sensory aspects of RAP. Results are discussed with respect to the cost-benefit of integrated medical and short-term psychological services. Evidence indicates that supervised home exercises, combined or not with manual therapy, can be beneficial for patients with non-specific chronic neck pain (NCNP). The objective of the study is to investigate the efficacy of preventive spinal manipulative therapy (SMT) compared to a no treatment group in NCNP patients. Another objective is to assess the efficacy of SMT with and without a home exercise program.
                Ninety-eight patients underwent a short symptomatic phase of treatment before being randomly allocated to either an attention-group (n = 29), a SMT group (n = 36) or a SMT + exercise group (n = 33). The preventive phase of treatment, which lasted for 10 months, consisted of meeting with a chiropractor every two months to evaluate and discuss symptoms (attention-control group), 1 monthly SMT session (SMT group) or 1 monthly SMT session combined with a home exercise program (SMT + exercise group). The primary and secondary outcome measures were represented by scores on a 10-cm visual analog scale (VAS), active cervical ranges of motion (cROM), the neck disability index (NDI) and the Bournemouth questionnaire (BQ). Exploratory outcome measures were scored on the Fear-avoidance Behaviour Questionnaire (FABQ) and the SF-12 Questionnaire.
                Our results show that, in the preventive phase of the trial, all 3 groups showed primary and secondary outcomes scores similar to those obtain following the non-randomised, symptomatic phase. No group difference was observed for the primary, secondary and exploratory variables. Significant improvements in FABQ scores were noted in all groups during the preventive phase of the trial. However, no significant change in health related quality of life (HRQL) was associated with the preventive phase.
                This study hypothesised that participants in the combined intervention group would have less pain and disability and better function than participants from the 2 other groups during the preventive phase of the trial. This hypothesis was not supported by the study results. Lack of a treatment specific effect is discussed in relation to the placebo and patient provider interactions in manual therapies. Further research is needed to delineate the specific and non-specific effects of treatment modalities to prevent unnecessary disability and to minimise morbidity related to NCNP. Additional investigation is also required to identify the best strategies for secondary and tertiary prevention of NCNP.
                ClinicalTrials.gov: NCT00566930. A prospective randomised trial comparing a single fraction of 8 Gy with 30 Gy in 10 daily fractions for the relief of metastatic bone pain was performed. In 28 months, 288 patients were randomised. Pain was assessed using a questionnaire completed by the patient at home on a daily basis. No difference was found in the speed of onset or duration of pain relief between the two treatment regimes, and pain relief was independent of the histology of the primary tumour.
This review was complicated by a lack of generally accepted diagnostic criteria for the diagnosis of TOS. There was very low quality evidence that transaxillary first rib resection decreased pain more than supraclavicular neuroplasty but no randomized evidence that either is better than no treatment. There is no randomized evidence to support the use of other currently used treatments. There is a need for an agreed definition for the diagnosis of TOS, especially the disputed form, agreed outcome measures and high quality randomized trials that compare the outcome of interventions with no treatment and with each other.
