Full Discussion

This paper deals with two case studies of onsite training on Ergonomics for small groups of non-OSH professionals from two state-owned companies from São Paulo State, Brazil. Both (1997 and 1998) training programs aimed at enabling small group of employees to function as an intern Ergonomics Committee. Their main and first task was to identify, evaluate, control and prevent risk factors and WRMD - Work Related Musculoskeletal Disorders, with or without the support of external consultant/ergonomists. This paper identifies and discusses main difficulties arising from such training programs and implementing work transformations. Some of the main difficulties may arise from the scheduling of short-term courses (36 to 48h of classes) for non-OSH professionals that are not used to group work, learning on matter as WRMD. Difficulties also originate from the nature of the task: (try) to enable mostly non-ergonomists/non OSH professionals to develop group-guided actions on matter that sometimes require immediate action, specialized knowledge and long-term experience in the field of Ergonomics and diagnosis of a company's demand. Last but not the least, the paper also points out key factors to work transformations: the placing of training programs within a company's OSH policy and context; group formation criteria for such training programs; course schedule, content, planning and evaluation; the need for full discussion of the short-term and the long-term results of the training program as well as of the follow-up of any work transformations.

Wrist Fusion

Fifteen patients with radioscapholunate (RSL) fusion for traumatic lesions of the radiocarpal junction, whose short-term results have been previously reported, were reassessed after an average follow-up time of 8 years. Five patients had undergone wrist fusion because of non-union or early progressive arthritis. Of the ten wrists with retained mobility, eight continued to function satisfactorily. Two wrists were painful for reasons other than secondary midcarpal arthritis. Patient satisfaction was comparable in both groups with the wrist score better for wrists with residual motion. The survival of RSL partial wrist fusion corresponded inversely with the number of preceding operations and the range of motion before partial fusion. Secondary midcarpal arthritis, if present, arose early and was well tolerated. Failures were strongly linked to technical mistakes and complications.

Aims There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data. Methods We assessed patients with a follow-up of at least five years after minimally invasive flip-button repair for high-grade AC joint dislocation. The clinical outcome was evaluated using the Constant score and a questionnaire. Ultrasound determined the coracoclavicular (CC) distance. Results of the current follow-up were compared to the short-term results of the same cohort. Results A total of 50 patients (three females, 47 males) were successfully followed up for a minimum of five years. The mean follow-up was 7.7 years (63 months to 132 months). The overall Constant score was 94.4 points (54 to 100) versus 97.7 points (83 to 100) for the contralateral side showing a significant difference for the operated shoulder (p = 0.013) The mean difference in the CC distance between the operated and the contralateral shoulder was 3.7 mm (0.2 to 7.8; p = 0.010). In total, 16% (n = 8) of patients showed recurrent instability. All these cases were performed within the first 16 months after introduction of this technique. A total of 84% (n = 42) of the patients were able to return to their previous occupations and sport activities. Comparison of short-term and long-term results revealed no significant difference for the Constant Score (p = 0.348) and the CC distance (p = 0.974). Conclusion The clinical outcome of MINAR is good to excellent after long-term follow-up and no significant differences were found compared to short-term results. We therefore suggest this is a reliable technique for surgical treatment of high-grade AC joint dislocation. Cite this article: Bone Joint J 2020;102-B(7):918–924.

Abstract The Swiss Group for Clinical Cancer Research (SAKK) conducted the SAKK 35/03 randomized trial (NCT00227695) to investigate different rituximab monotherapy schedules in patients with follicular lymphoma (FL). Here, we report their long-term treatment outcome. Two-hundred and seventy FL patients were treated with 4 weekly doses of rituximab monotherapy (375 mg/m2); 165 of them, achieving at least a partial response, were randomly assigned to maintenance rituximab (375 mg/m2 every 2 months) on a short-term (4 administrations; n = 82) or a long-term (up to a maximum of 5 years; n = 83) schedule. The primary end point was event-free survival (EFS). At a median follow-up period of 10 years, median EFS was 3.4 years (95% confidence interval [CI], 2.1-5.5) in the short-term arm and 5.3 years (95% CI, 3.5-7.5) in the long-term arm. Using the prespecified log-rank test, this difference is not statistically significant (P = .39). There also was not a statistically significant difference in progression-free survival or overall survival (OS). Median OS was 11.0 years (95% CI, 11.0-NA) in the short-term arm and was not reached in the long-term arm (P = .80). The incidence of second cancers was similar in the 2 arms (9 patients after short-term maintenance and 10 patients after long-term maintenance). No major late toxicities emerged. No significant benefit of prolonged maintenance became evident with longer follow-up. Notably, in symptomatic patients in need of immediate treatment, the 10-year OS rate was 83% (95% CI, 73-89%). These findings indicate that single-agent rituximab may be a valid first-line option for symptomatic patients with advanced FL.

Severe Hallux Valgus

The senior author's (R.C.) first 25 patients (37 feet) treated with a combination proximal crescentic osteotomy and distal soft-tissue reconstruction made up the patient cohort. All 25 patients were reviewed at a minimum of one year post-op (short-term follow-up) and 20/25 (31/37 feet) were reviewed again at a mean 12.2 years (range 11.4 to 13.0 yrs) post-op (long-term follow-up). This allowed for a comparison of short- and long-term results and led to a long-term follow-up rate of 84% (31/37 feet, mean 12.2 yrs). Clinical, radiographic and patient outcome measures were obtained and compared pre-op and at short- and long-term follow-up. The mean preoperative hallux valgus (HVA) and intermetatarsal angles (IMA) were 37° and 16° respectively. The mean HVA correction was 24° and IMA correction 10° at long-term follow-up with no tendency toward recurrence. Sesamoid position and first MTP subluxation was markedly improved postoperatively and the correction was maintained at long-term follow-up. Patients were asked about their satisfaction in terms of pain, appearance and motion. At long-term follow-up, more than 90% of patients were completely satisfied with pain and motion and greater than 80% with their appearance. Ninety-four percent of patients said they would have the operation again. The AOFAS clinical rating scale for the hallux was calculated retrospectively for pre-op and short-term follow-up and prospectively for long-term follow-up. The mean pre-op score was 37/100 (16 to 60) which significantly improved to 92/100 (67 to 100) at both follow-up periods, suggesting no evidence of decrease in outcome over time. Complications included two patients (5%) that were over-corrected into varus (one symptomatic, one asymptomatic), and four patients (11%) that were undercorrected, developing asymptomatic recurrences (>10° increase HVA) at long-term follow-up. In addition, two patients (5%) developed new transfer lesions postoperatively, likely related to technical error (one varus overcorrection, one dorsiflexion malunion). In conclusion, the long-term results, with a mean follow-up of 12.2 years, of the resection realignment procedure for moderate to severe hallux valgus are generally excellent and the complication rate is low and acceptable. Attention to detail, avoiding both undercorrection, which can lead to recurrence, and overcorrection, which can cause symptomatic varus, is essential.

AbstractThe traditional meatoplasty operations performed for chronic otitis externa, which has entered the ‘fibrotic’ phase, are often unsatisfactory because the results in terms of canal patency, hearing gain and patient satisfaction are variable. Although the use of laser in chronic ear surgery is well recognized, it has not been previously reported as a meatoplasty technique. Ten KTP laser meatoplasty operations were performed on eight patients with chronic otitis externa. This pilot study shows the technique to be effective, fast and with a high patient satisfaction rate in the short-term (mean follow-up period 9.3 months). The average increase in hearing thresholds was 24 dB HL. Significant patient benefit was obtained in at least six out of eight patients using the Belfast rule of thumb. The technique has many advantages over the traditional meatoplasty operations but the long-term results require evaluation.

Abstract OBJECTIVE Medically refractory cluster headache (CH) is a debilitating condition for which few surgical modalities have proven effective. Previous reports involving short-term follow-up of CH patients have reported modest degrees of pain relief after radiosurgery of the trigeminal nerve ipsilateral to symptom onset. With the recent success of deep brain stimulation as a surgical modality for these patients, it becomes imperative for the long-term risks and benefits of radiosurgery to be more extensively delineated. To address this issue, we present our findings from the largest retrospective series of patients undergoing radiosurgery for CH with extended follow-up periods. METHODS Between 1997 and 2001, 10 patients with CH underwent gamma knife radiosurgery at our institution. All patients fulfilled clinical criteria for treatment, including complete resistance to pharmacotherapy (usually methysergide, verapamil, and lithium), pain primarily localized to the ophthalmic division of the trigeminal nerve, and psychological stability. The mean age at radiosurgery was 40.3 years (range, 26–62 yr), and the average CH duration was 11.3 years (range, 2–21 yr). Patients received 75 Gy to the 100% isodose line delivered to the most proximal part of the trigeminal nerve where the 50% isodose line was outside the brainstem (4-mm collimator), with a mean follow-up period of 39.7 months (range, 5–88 mo). Pain relief was defined as excellent (free of CH with minimal or no medications), good (50% reduction of CH severity and frequency with medications), fair (25% reduction of CH severity and frequency with medications), or poor (less than 25% reduction of CH severity and frequency with medications). RESULTS After radiosurgery, pain relief was poor in nine patients and fair in one patient. Six patients with poor to fair relief initially experienced excellent to good relief (range, 2 wk–2 yr after treatment) before regressing. Five patients (50%) experienced trigeminal nerve dysfunction, manifesting predominantly as facial numbness after treatment. CONCLUSION Although some patients may experience short-term pain relief, none had relief sustainable for longer than 2 years. The results from this series indicate that radiosurgery of the trigeminal nerve does not provide long-term pain relief for medically refractory CH.

The dynamic self-regulating prosthesis (protesi autoregolantesi dinamica, PAD) is a double-layered prosthesi, in use since 1992 in inguinal hernia repair. In 1999, we published the short-term results on 500 patients and herein we report the long-term follow-up. Five hundred eighty-five PAD procedures were performed on 500 adult male, unselected patients. Hernias were unilateral in 415 patients, were bilateral in 85 patients, were direct in 197 patients (33.7%), were indirect in 269 patients (46.0%), and were combined in 119 patients (20.3%). Four hundred sixty-four patients were alive at the follow-up period of minimum 5 years, whereas 36 died (7.2%) of causes unrelated to the hernia. No information was available on 73 patients (14.6%). Therefore, the follow-up was consisted of 391 patients (78.2%) with 469 hernias. The recurrence and testicular atrophy rates were nil. Three patients (0.77%) presented chronic pain and 18 (4.6%) suffered persistent discomfort or paresthesia. A hydrocoele was observed in one patient (0.2%). The long-term data confirm the efficacy of the dynamic self-regulating posthesis hernioplasty. We propose it as a standard of care in all cases of primary inguinal hernia in adult males, retaining it as a definitive and comfortable solution.

Introduction. Sling urethropexy is considered the «gold standard» surgical treatment for stress urinary incontinence in women. However, the long-term results of such operations have not yet been fully studied.Purpose of the study. To evaluate the results of using various options for sling operations at different periods of postoperative follow-up.Materials and methods. In 698 women aged 42 - 68 years (median — 54 years) suffering stress incontinence were used 4 variants of sling operations according to the database of the S.P. Botkin City Clinical Hospital: TVT retropubic technique; transobturator technique TVT-O («inside-out»); transobturator technique TOT («outside-in»); mini sling system. The period of postoperative follow-up was 6 - 139 months (median 79 months). Evaluation of treatment results was carried out according to the following periods of postoperative follow-up: short-term (up to 1 year inclusive); mediumterm (a period from 1 to 5 years inclusive); long-term (over 5 years). The success of the treatment was determined by the criterion of the absence of urine involuntary loss during the cough test and the 1-hour pad test.Results. Treatment success in the entire sample of patients was 96.1% (671 / 698) for the short-term criterion, 93.1% (591 / 635) for the medium-term criterion and 86.2% for the long-term criterion (467 / 642). The effectiveness of short-term treatment after TVT was 97%, TVT-O — 95.8%, TOT — 96.2%, mini-sling system — 95.5%, in medium-term — 92.2%, 93.1%, 90.9% and 92.3%, respectively, for long-term — 87.1%, 86.2%, 85.2% and 85%, respectively. There were no significant differences between the indicated variants of sling operations in terms of treatment efficacy for all observation periods (p > 0.05). Intra and early postoperative complications were noted in 51 (7.3%) cases, late — in 79 (11.3%). There were no significant differences in the incidence of both categories of complications between the surgical techniques used (p > 0.05). Only surgical experience significantly affects the risk of recurrent urinary incontinence after surgery, early and late postoperative complications.Conclusions. The success of surgical treatment for stress urinary incontinence in women does not significantly depend on the type of sling surgery but depends mainly on the surgical experience. Therefore, it is advisable to use sling operations in hospitals with extensive experience in this area.

Double Stent

OBJECTIVEThe endovascular treatment of complex bifurcation aneurysms possessing a neck that incorporates multiple side branches remains a surgical challenge. Double-stent–assisted coiling techniques, such as those with stents in an X and Y configuration, enable the endovascular treatment of wide-necked complex intracranial bifurcation aneurysms. However, the intraluminal struts at the intersection point in X- and Y-stents are not amenable to endothelialization, which may lead to thromboembolic complications. Stenting in the T configuration is a relatively new double-stent coiling technique. T-stenting differs from X- or Y-stenting in that there are no overlapping or intersecting stent segments. Promising short-term results of T-stent–assisted coiling were recently reported. However, the long-term results have not yet been demonstrated. This retrospective study investigated the long-term angiographic and clinical results in patients with wide-necked complex intracranial bifurcation aneurysms treated with T-stent–assisted coiling.METHODSA retrospective review was performed to identify patients with wide-necked complex intracranial bifurcation aneurysms treated with T-stent–assisted coiling at 4 institutions. The technical success and the initial and follow-up clinical and angiographic outcomes were assessed. Aneurysm filling status was assessed according to the Raymond classification. Periprocedural and delayed complications were reviewed. The neurological status of the patients was evaluated using the modified Rankin Scale (mRS).RESULTSOne hundred two aneurysms in 102 patients (54 females), whose mean age was 57.9 ± 13.0 years, were included in the study. T-stenting was performed successfully in all patients. Immediate postprocedural angiography revealed complete occlusion in 83.3% of patients. Periprocedural complications developed in 13.7%, resulting in permanent morbidity in 1.9% and death in 1%. Eighty patients (78.4%) had at least one follow-up DSA examination performed at 6 months or later following the endovascular procedure. The mean duration of angiographic follow-up was 30.0 ± 16.3 months. The last follow-up examinations showed complete occlusion in 90.0% of patients. During the follow-up period, only 1 patient (1.3%) required retreatment. Delayed thromboembolic complications were observed in 4 patients (3.9%) without permanent morbidity. The mRS scores of all patients at the last clinical follow-up were between 0 and 2.CONCLUSIONSThe short-term angiographic findings showed that T-stent–assisted coiling is a feasible and effective endovascular method to treat wide-necked complex bifurcation aneurysms. The long-term angiographic follow-up results suggest that T-stent–assisted coiling provides a durable treatment for wide-necked complex bifurcation aneurysms with favorable clinical outcomes, demonstrating the long-term safety of T-stent–assisted coiling.

Background The results of both nonoperative and surgical treatments for lateral epicondylitis of the elbow have been inconsistent. Shock wave therapy has been shown to have a favorable short-term effect in treating this condition. Hypothesis Shock wave therapy is an effective treatment for patients with lateral epicondylitis of the elbow and long-term results will be as favorable as short-term ones. Study Design Case series. Methods The effect of shock wave therapy was investigated in 57 patients with lateral epicondylitis of the elbow. Forty-three patients (24 men and 19 women with an average age of 46 years) with 1 to 2 years of follow-up were included in this study. In addition, six patients were treated with a sham procedure as a control group. Each patient was treated with 1000 impulses of shock wave therapy at 14 kV to the affected elbow. A 100-point scoring system was used for evaluating pain, function, strength, and elbow range of motion. Results Twenty-seven elbows (61.4%) were free of complaints, 13 (29.5%) were significantly better, 3 (6.8%) were slightly better, and 1 (2.3%) was unchanged. In the control group, the results were unchanged in all six patients. There were no device-related problems and no systemic or local complications. Conclusions Shock wave therapy is a safe and effective modality in the treatment of patients with lateral epicondylitis of the elbow.
