Forty-three patients were randomly allocated to undergo either trapeziectomy alone (control) or with a ligament reconstruction and tendon interposition (LRTI) using an abductor pollicis longus tendon slip. The patients were reviewed at a median 13 (range, 7-29) months after surgery. The demographic characteristics, severity of disease and pre-operative clinical measurements of the two study groups were indistinguishable but LRTI lengthened the operation by approximately 15 minutes. Both groups expressed equal satisfaction with the operation and there were no significant differences between the two treatment groups. Simple trapeziectomy is an effective operation for osteoarthrosis at the base of the thumb and the addition of a ligament reconstruction was not shown to confer any additional benefit. This prospective study compared the outcome--subjective, objective and radiographic--of two surgical techniques for treating basal joint arthritis of the thumb: a "simple" trapeziectomy (group I) and a ligament reconstruction/tendon (group II) interposition technique. There were respectively 22 patients in group I and 34 in group II, all women with primary osteoarthritis. Both techniques gave favourable results and there were no significant differences for pain relief, patient satisfaction, mobility, DASH-score, key pinch force and gripping force. However in group II, the trapezial height was better preserved indicating that the proximal migration of the thumb was prevented or limited. There was also a significant correlation between the remaining trapezial space and key pinch force. : According to a recent metaanalysis study, there is strong evidence to support the view that transcutaneous electrical nerve stimulation (TENS) is an effective treatment for managing osteoarthritis (OA) knee pain. However, there is limited evidence showing its effectiveness in improving physical function. This study examined whether TENS alone can improve physical function in terms of range of knee motion and the Timed-Up-and-Go Test.
                : Subjects were randomly allocated into 2 groups receiving TENS at 100 Hz or a placebo TENS. Outcome measures included: 1) visual analog scale for measuring the intensity of the present pain, 2) Timed-Up-and-Go Test, and 3) range of knee motion (ROM). Repeated-measures analysis of variance and Pearson correlation were used for data analyses.
                : By day 10, TENS produced a significantly greater increase in maximum knee ROM than the placebo group (P = 0.033). TENS also significantly increased the pain-limited knee ROM across sessions, but the between-group difference was short of significance (P = 0.067). The decrease in time in performing the Timed-Up-and-Go Test was also not significantly different between the 2 groups. A moderate correlation was observed between the reduction in pain scores and the improvement in the Timed-Up-and-Go Test.
                : Our findings suggested that TENS did improve some of the physical parameters but over 10 days was unable to produce significant improvement in functional performance among people with knee OA. A larger-scale study with the assessment of other functional outcomes may be required to clarify if TENS could improve function in people with knee OA. Also, exercise can be considered to be an important adjunct treatment to TENS to improve function significantly. A randomized parallel-group comparative trial with a 1-year follow-up period was performed.
                To compare the effect of a comprehensive functional restoration program involving intensive physical training, ergonomic training, and behavioral support (39 hours per week for 3 weeks) with the effect of outpatient intensive physical training (1.5 hours three times per week for 8 weeks).
                Nonrandomized studies conducted in the United States favor functional restoration for patients with chronic low back pain. Two previously reported randomized studies from the authors' Back Center in Copenhagen concur with this recommendation, although the positive effects in one of the studies had faded out after 2 years. Randomized functional restoration studies in Canada and Finland have failed to demonstrate any substantive effect.
                Initially, 138 patients with chronic low back pain were included in the current study. They then were randomized to either functional restoration (n = 64) or outpatient intensive physical training (n = 74). Of the initial 138 patients, 11 never started (5 and 6, respectively); 21 dropped out during treatment (8 and 13); and 7 of the graduates did not take part in the 1-year follow-up evaluation (3 and 4). The conclusions were drawn from the 99 patients (48 and 51, respectively) who graduated and participated in a 1-year follow-up evaluation. The median age of the patients was 42 years (range, 21-55 years) The female-to-male ratio was 68 to 31, and the median sick leave days during the preceding 3 years was 180 (range, 0-1080 days). The average back pain was rated 5.5 on a scale of 0 (no pain) to 10 (maximal pain). For these variables, there were no important differences between the groups. However, the functional restoration group tended to be more capable of work at baseline (58% vs 42%; P = 0.09).
                At the 1-year follow-up evaluation, overall assessment favored functional restoration. Otherwise, no significant differences were observed regarding work capability, sick leave for those at work, health care contacts,back pain, leg pain, or self-reported activities of daily living.
                Only in terms of overall assessment, the functional restoration program was superior to a comparatively short time-consuming outpatient physical training program.
                It may be that lower economic benefits during sick leave in the United States lead to favorable results from functional restoration programs, whereas greater benefits in Canada, Finland, and Denmark result in different conclusions. Finally, it may be that the difference in results across studies points simply to whether the studies were randomized. To assess the effects of a stress-reduction program on pain, psychological function, and physical function in persons with systemic lupus erythematosus (SLE) who experience pain.
                Ninety-two SLE patients were assigned randomly to receive either biofeedback-assisted cognitive-behavioral treatment (BF/CBT), a symptom-monitoring support (SMS) intervention, or usual medical care (UC) alone.
                BF/CBT participants had significantly greater reductions in pain and psychological dysfunction compared with the SMS group (pain, P = 0.044; psychological functioning, P < 0.001) and the UC group (pain, P = 0.028; psychological functioning, P < 0.001). BF/CBT had significantly greater improvement in perceived physical function compared with UC (P = 0.035), and improvement relative to SMS was marginally significant (P = 0.097). At a 9-month followup evaluation, BF/CBT continued to exhibit relative benefit compared with UC in psychological functioning (P = 0.023).
                This study supports the utility of a brief stress management program for short-term improvement in pain, psychological function, and perceived physical function among persons with SLE who experience pain. Endovenous laser (EVL) ablation of the great saphenous vein (GSV) is thought to minimize postoperative morbidity and reduce work loss compared with high ligation and stripping (HL/S). However, the procedures have not previously been compared in a randomized trial with parallel groups where both treatments were performed in tumescent anesthesia on an out-patient basis.
                Patients with varicose veins due to GSV insufficiency were randomized to either EVL (980 nm) or HL/S in tumescent anesthesia. Miniphlebectomies were also performed. Patients were examined preoperatively and at 12 days, and 1, 3, and 6 months postoperatively. Sick leave, time to normal physical activity, pain score, use of analgesics, Aberdeen score, Medical Outcomes Study Short Form-36 quality-of-life score, Venous Clinical Severity Score (VCSS), and complication rates were investigated. The total cost of the procedures, including lost wages and equipment, was calculated. Cost calculations were based on the standard fee for HL/S with the addition of laser equipment and the standard salary and productivity level in Denmark.
                A follow-up of 6 months was achieved in 121 patients (137 legs). The groups were well matched for patient and GSV characteristics. Two HL/S procedures failed, and three GSVs recanalized in the EVL group. The groups experienced similar improvement in quality-of-life scores and VCSS score at 3 months. Only one patient in the HL/S group had a major complication, a wound infection that was treated successfully with antibiotics. The HL/S and EVL groups did not differ in mean time to resume normal physical activity (7.7 vs 6.9 calendar days) and work (7.6 vs 7.0 calendar days). Postoperative pain and bruising was higher in the HL/S group, but no difference in the use of analgesics was recorded. The total cost of the procedures, including lost wages, was euro 3084 ($3948 US) in the HL/S and euro 3396 ($4347 US) in the EVL group.
                This study suggests that the short-term efficacy and safety of EVL and HL/S are similar. Except for slightly increased postoperative pain and bruising in the HL/S group, no differences were found between the two treatment modalities. The treatments were equally safe and efficient in eliminating GSV reflux, alleviating symptoms and signs of GSV varicosities, and improving quality of life. Long-term outcomes, particularly with respect to recurrence rates, shall be investigated in future studies, including the continuation of the present. Although laparoscopic cholecystectomy has rapidly become routine practice in the UK, there has been no rigorous comparison of it with open cholecystectomy. In our trial, 302 patients were randomised to laparoscopic or minilaparotomy cholecystectomy. Recovery after surgery was assessed by length of hospital stay, outpatient review at 10 days and 4 weeks, and patient questionnaires 1, 4, and 12 weeks after surgery. The mean operation time was 14 min shorter for minilaparotomy, while median post-operative hospital stay was 2 days shorter after laparoscopic cholecystectomy. The hospital costs were about 400 pounds greater for the laparoscopic procedure. Laparoscopic patients returned to work in the home sooner; at 1 week, they had better physical and social functioning, were less limited by physical problems, and had less pain and depression. At 4 weeks, only physical functioning and depression scores were better in the laparoscopic group, and by 3 months there were no differences. Laparoscopic patients were more satisfied with the appearance of their scars. The incidence of complications after both procedures was 20%. Compared to minilaparotomy cholecystectomy, laparoscopic cholecystectomy results in shorter hospital stay, less postoperative dysfunction, and quicker return to normal activities, but is more costly. Vertical banded gastroplasty (VBG) is a frequently used surgical procedure for the treatment of morbid obesity. It can be done open (OVBG) or laparoscopic (LVBG). The aim of this double-blind randomized clinical trial was to compare the postoperative outcome and 1-year follow-up of 2 cohorts of patients who underwent either OVBG or LVBG.
                30 patients with morbid obesity were randomized into 2 groups (14 OVBG and 16 LVBG). Pain intensity, analgesic requirements, respiratory function, and physical activity were blindly analyzed during the first 3 postoperative days. Complications, weight loss, and cosmetic results after 1 year follow-up were evaluated.
                Both groups were highly comparable before surgery. Surgical time was longer in the laparoscopic procedure. Patients in this group required less analgesics during the first postoperative day. There was an earlier recovery in the expiratory and inspiratory forces, as well as faster recovery of physical activities in patients who underwent LVBG. Postoperative complications were more frequent in the open group. Excess body weight loss after 1 year was similar in both groups. Cosmetic results were significantly better in the laparoscopic group.
                LVBG had advantages over the open procedure in terms of analgesic requirements, respiratory function, postoperative recovery, and cosmetic results. To compare gasless laparoscopy with conventional laparoscopy using CO2 pneumoperitoneum.
                Women undergoing bilateral laparoscopic tubal coagulation (LTC) were randomly assigned to one of two laparoscopy procedures: (1) a gasless laparoscopy system consisting of an intraabdominal fan retractor and electrically powered mechanical arm, and (2) standard CO2 pneumoperitoneum laparoscopy. The two laparoscopic procedures were compared on the basis of intraoperative visualization, operation duration, procedural difficulty, ventilatory parameters, hemodynamic stability, and postoperative pain and nausea.
                Significant disadvantages for the surgeon (increased technical difficulty, poorer visualization, longer operative times) and patient (greater postoperative pain and nausea) were seen with the gasless system. Because of these findings, the study was prematurely terminated after only 18 patients had participated. Intraoperative ventilatory and hemodynamic parameters were more stable in the gasless laparoscopy groups; however, the differences were not clinically significant in this population of healthy patients.
                The markedly increased technical difficulty and absence of clear clinical benefits for the healthy patient led to the conclusion that laparoscopy with CO2 pneumoperitoneum is preferable for routine LTC and most laparoscopic procedures in the pelvis. Gasless laparoscopy may be of benefit for the fragile patient with a compromised cardiovascular system who may suffer complications from hypercarbenemia. Although vision therapy has reportedly been very successful in elimination of asthenopic symptoms in adults with convergence insufficiency, controlled studies have not been performed, and a clinical bias exists against prescribing vision therapy for adults with convergence insufficiency.
                Sixty adult males over the age of 40 years (median age, 65 years) with convergence insufficiency were divided into three treatment groups: office-based vision therapy with supplementary home therapy, home therapy only, and a control group.
                Vision therapy was successful in 61.9% of patients who received in-office plus home therapy, in 30% of patients who received home therapy only, and in 10.5% of the control group. The success rate for patients who received active in-office vision therapy supplemented with home procedures was significantly greater than that for controls. Home therapy alone was less successful than in-office therapy. The success rate obtained with home therapy alone was not significantly greater than that demonstrated by controls.
                Vision therapy is effective in eliminating asthenopia and improving convergence function in adult patients. In-office therapy combined with home therapy tends to produce better results than does home therapy alone. A randomized controlled trial was conducted.
                To determine the efficacy of osteopathic manipulative treatment as a complementary treatment for chronic nonspecific low back pain.
                Osteopathic manipulative treatment may be useful for acute or subacute low back pain. However, its role in chronic low back pain is unclear.
                This trial was conducted in a university-based clinic from 2000 through 2001. Of the 199 subjects who responded to recruitment procedures, 91 met the eligibility criteria. They were randomized, with 82 patients completing the 1-month follow-up evaluation, 71 completing the 3-month evaluation, and 66 completing the 6-month evaluation. The subjects were randomized to osteopathic manipulative treatment, sham manipulation, or a no-intervention control group, and they were allowed to continue their usual care for low back pain. The main outcomes included the SF-36 Health Survey, a 10-cm visual analog scale for overall back pain, the Roland-Morris Disability Questionnaire, lost work or school days because of back pain, and satisfaction with back care.
                As compared with the no-intervention control subjects, the patients who received osteopathic manipulative treatment reported greater improvements in back pain, greater satisfaction with back care throughout the trial, better physical functioning and mental health at 1 month, and fewer cotreatments at 6 months. The subjects who received sham manipulation also reported greater improvements in back pain and physical functioning and greater satisfaction than the no-intervention control subjects. There were no significant benefits with osteopathic manipulative treatment, as compared with sham manipulation.
                Osteopathic manipulative treatment and sham manipulation both appear to provide some benefits when used in addition to usual care for the treatment of chronic nonspecific low back pain. It remains unclear whether the benefits of osteopathic manipulative treatment can be attributed to the manipulative techniques themselves or whether they are related to other aspects of osteopathic manipulative treatment, such as range of motion activities or time spent interacting with patients, which may represent placebo effects.
Although it appears that no one procedure produces greater benefit in terms of pain and physical function, there was insufficient evidence to be conclusive. Trapeziectomy has fewer complications than trapeziectomy with LRTI.
