A 52-year-old man with Parkinson disease (PD) of 9 years’ duration was referred to the DBS clinic for medication-refractory severe unilateral rest and re-emergent tremor and frequent motor fluctuations. He was approved for DBS, with debate over the optimal target to treat severe tremor and fluctuations (subthalamic nucleus [STN] plus/minus the ventral intermediate [Vim] thalamus) and unilateral versus bilateral implantation. The committee decided to perform unilateral STN lead placement first, to provide benefit for both motor fluctuation and tremor, with the option of adding Vim concurrently if required. Intraoperatively, there was incomplete tremor capture, so a second lead was placed in Vim with success. Subsequent DBS programming achieved marked improvement of tremor and fluctuations at low stimulation, although side effects necessitated bipolar configurations in both leads. The patient reported excellent sustained tremor suppression at 2-year follow-up, although motor fluctuations recurred. This case illustrates that for intraoperative stimulation-refractory PD tremor, consideration can be given to adding a second Vim DBS target (dual DBS targets).

Object. The tremor-suppression effect resulting from long-term stimulation of the thalamic nucleus ventralis intermedius (Vim) and the nucleus ventralis oralis posterior (Vop) was examined in the treatment of parkinsonian, essential, and poststroke tremor. Methods. After identifying the accurate anterior border of the nucleus ventrocaudalis (Vc), deep brain stimulation (DBS) electrodes with four contacts were inserted into the Vim—Vop region at an angle of between 40 and 50° from the horizontal plane of the anterior commissure—posterior commissure line. Two distal contacts were placed on the Vim side and two proximal contacts on the Vop side. The best sites of stimulation and parameters of bipolar stimulation were selected in each case and follow-up examinations were conducted for at least 2 years. In all 15 cases of parkinsonian tremor (18 sides) and in 14 of 15 cases of essential tremor (24 of 25 sides), cathodal stimulation of the Vim side with anodal stimulation of the Vop side was determined to be the best choice to suppress the tremor. In poststroke tremor, however, six of 12 cases (six of 12 sides) were selected for cathodal stimulation of the Vop side with anodal stimulation of the Vim side. The average stimulation intensity 1 month after initiation of DBS was 1.61 V in cases of parkinsonian tremor, 1.99 V in cases of essential tremor, and 2.39 V in cases of poststroke tremor. A comparison of stimulation intensities required at 1 and 24 months after initiation of DBS revealed that the lowest effective stimulation intensity increased 24.2% in cases of parkinsonian tremor, 21% in cases of poststroke tremor, and 46.9% in cases of essential tremor. Suppression of tremor was achieved in all cases (42 cases, 55 sides) during a period of 2 years. Nevertheless, two cases of poststroke tremor required dual-lead stimulation at the unilateral Vim—Vop region from the start of DBS, and two cases of essential tremor and one case of poststroke tremor required a stimulation intensity that was high enough to evoke unpleasant paresthesia and slight motor contraction during the follow-up period. Conclusions. Effective stimulation sites and stimulation intensities differ in different kinds of tremor; Vim and Vop stimulation is necessary in many cases. Interactions of the Vim and Vop under the control of interconnected areas of the motor circuitry may play an important role in both the development and DBS-induced suppression of tremor.

Abstract Background Amelogenesis imperfecta is a hereditary malformation showing various manifestations regarding enamel dysplasia. This case report shows a 9-year follow-up after restorative treatment of a 16-year old female patient affected by a hypoplastic type of amelogenesis imperfecta. The caries-free, hypersensitive teeth of the patient were restored by direct dentin adhesive composite restorations performed in total etch technique. Case presentation After rehabilitation the patient reported a marked improvement of the mastication ability and quality of life especially during food intake. Accumulation of plaque was reduced and the ability to perform adequate oral hygiene was improved. During follow-up of 9 years recurring secondary caries and debonding of fillings were recognized and retreated. Conclusions The retrospective assessment exhibits that the performed restorative treatment prolonged the time until further treatment has to be considered, such as prosthetic treatment.

Shoulder instability is a complex phenomenon and repeated dislocation due to persistent abnormal muscle patterning can be challenging to manage. This case report describes the treatment of a 21-year old female who presented with repeated atraumatic anteroinferior shoulder dislocation due to abnormal muscle patterning. Management involved physiotherapy to re-educate muscle control combined with botulinum toxin injections into pectoralis major, latissimus dorsi and teres major prior to shoulder stabilization surgery. The patient reported marked improvement as reflected by improved scores on the Oxford Shoulder Instability Score and Western Ontario Shoulder Instability Score. Benefits were maintained at 3 year follow-up.

A 40 years old man presented with progressive weakness and distal paraesthesia of limbs with difficulty in walking for last seven years. As the patient was not investigated thoroughly, a diagnostic dilemma was persisted. This patient went abroad & investigated thoroughly and yet not reached to a confirm diagnosis. Subsequently this patient reported to us and diagnosed it to be a case of Idiopathic Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) responded to oral steroid therapy. After follow-up, this patient showed marked improvement. So diagnostic dilemma that persisted with such a patient that showed improvement with treatment and a challenge to a treatable condition had encouraged us to report the case.

A 79-year-old woman with medication-refractory disabling orthostatic tremor (OT) of 15 years’ duration was referred for deep brain stimulation (DBS). She reported leg tremor within seconds of standing that spread to the trunk and upper limbs within 30 seconds, requiring her to sit down. She carried a stool everywhere to compensate for inability to stand. She had failed several medications, including clonazepam. Clinical exam showed visible and palpable leg tremor within seconds of standing. Surface electrophysiology confirmed a 15- to 16-Hz tremor on standing that transmitted to the arms with load-bearing. She was approved for bilateral ventral intermediate thalamic DBS. A microlesional effect was observed on standing up in the operating room following bilateral lead placement. Outpatient DBS programming resulted in further tremor suppression clinically, confirmed by movement electrophysiology with DBS turned off and on. At 3-year follow-up, the patient could stand for 10 to 15 minutes, with only minor shifts in stance, and no longer needed a stool. There was an observed difference in tremor severity and standing time with DBS turned on and off. This case adds to the growing body of literature on the benefit of bilateral thalamic DBS for medication-refractory OT. However, whether there is a more optimal DBS target is not yet known.

BACKGROUND Cancer survivors experience unmet needs during follow-up. Besides recurrence, a follow-up includes detection of late side effects, rehabilitation, palliation and individualized care. OBJECTIVE We aimed to describe the development and evaluate the feasibility of an intervention providing individualized cancer follow-up supported by electronic patient-reported outcomes (e-PRO). METHODS The study was carried out as an interventional study at a Surgical and a Gynecological Department offering complex cancer surgery and follow-up for advanced cancer. The e-PRO screened for a priori defined clinical important symptoms and needs providing individualized follow-up. We included following questionnaires in the e-PRO; the general European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and the EORTC validated for colorectal and ovarian cancer patients. To support individualization, we included three prioritized issues of the patient’s preference in each e-PRO. The response-algorithm was aggregated based on the severity of the patient’s response. To ensure the sensitivity of the e-PRO, we performed semi-structured interviews with five patients. All clinicians (surgeons and gynecologists) performing the consultations reviewed the e-PRO. The evaluation was divided in two, 1)The feasibility was assessed by a)Patients’ response rate of the e-PRO, b)Number of follow-up visits documenting the use of e-PRO and c)Patients’ prioritized issues prior to the consultation(‘yes’ / ‘no’), and after the follow-up 2)Patients assessment of a)The need and purpose of the follow-up visit and b)the support provided during the follow-up visit. RESULTS In total, 187 patients were included in the study, of which 73%(n=136/187) patients responded to the e-PRO and were subjected to an individualized follow-up. The e-PRO was documented as applied in 79% of the follow-up visits. In total, 23% of the prioritized issues did not include a response. Stratified by time since surgery, significantly more patients did not fill out a prioritized issue had a follow-up >6 months since surgery. In total, 72 % follow-up visits were evaluated to be necessary in order to discuss the outcome of the CT scan, symptoms, and/or prioritized issues. Contrary, 19% of the follow-up visits were evaluated to be necessary only to discuss the result of the CT scan. A range from 19.3–56.3% of patients assessed the follow-up visit to provide support with respect to physical (42% of patients), mental (56%), sexual (19%) or dietary (27%) issues. Further, a range from 34–60% of the patients reported that they did not need support regarding physical (43% of patients), mental (34%), sexual (63%) or dietary (57%) issues. CONCLUSIONS An individualized follow-up based on e-PRO is feasible, and support most patients surgically treated for advanced cancer. However, results indicate that follow-up based on e-PRO may not be beneficial for all patients and circumstances. A thorough cost-benefit analysis may be warranted before implementation in routine clinic.

Aims The aim of this study was to evaluate health-related quality of life (HRQoL) and joint function in tenosynovial giant cell tumour (TGCT) patients before and after surgical treatment. Patients and Methods This prospective cohort study run in two Dutch referral centres assessed patient-reported outcome measures (PROMs; 36-Item Short-Form Health Survey (SF-36), visual analogue scale (VAS) for pain, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)) in 359 consecutive patients with localized- and diffuse-type TGCT of large joints. Patients with recurrent disease (n = 121) and a wait-and-see policy (n = 32) were excluded. Collected data were analyzed at specified time intervals preoperatively (baseline) and/or postoperatively up to five years. Results A total of 206 TGCT patients, 108 localized- and 98 diffuse-type, were analyzed. Median age at diagnosis of localized- and diffuse-type was 41 years (interquartile range (IQR) 29 to 49) and 37 years (IQR 27 to 47), respectively. SF-36 analyses showed statistically significant and clinically relevant deteriorated preoperative and immediate postoperative scores compared with general Dutch population means, depending on subscale and TGCT subtype. After three to six months of follow-up, these scores improved to general population means and continued to be fairly stable over the following years. VAS scores, for both subtypes, showed no statistically significant or clinically relevant differences pre- or postoperatively. In diffuse-type patients, the improvement in median WOMAC score was statistically significant and clinically relevant preoperatively versus six to 24 months postoperatively, and remained up to five years’ follow-up. Conclusion Patients with TGCT report a better HRQoL and joint function after surgery. Pain scores, which vary hugely between patients and in patients over time, did not improve. A disease-specific PROM would help to decipher the impact of TGCT on patients’ daily life and functioning in more detail. Cite this article: Bone Joint J 2019;101-B:272–280.

Abstract Background The purpose of this study was to determine the mid-term clinical, radiographic and health-related quality of life (HRQoL) outcomes and define the survival rate in patients who had undergone revision total knee arthroplasty (TKA) using the single rotating hinged knee (RHK) design. Methods Between January 2004 and December 2013, 125 revision TKAs were performed at our institution using the single RHK implant. We conducted both a retrospective analysis of prospectively collected outcome data of these patients and a prospective follow-up study of all 39 living patients (41 knees). The follow-up phase included an optional extra follow-up visit, PROM questionnaires, and plain radiographs. Results The ten-year Kaplan-Meier survival rate of the revision RHK knees was 81.7% (95% CI 71.9–91.6%) with re-revision for any reason as the endpoint. Overall, 15 knees (12% of the total) underwent re-revision surgery during the follow-up. The median follow-up was 6.2 years (range, 0–12.7 years) post-operatively for the baseline group. One mechanical hinge mechanism-related failure occurred without any history of trauma or infection. At the time of the final follow-up, the majority of patients evinced a fairly good clinical outcome measured with patient-reported outcome measures and none of the components were radiographically loose. Conclusion We found that in patients undergoing complex revision TKA, fairly good functional outcome and quality of life can be achieved using an RHK implant. Further, it seems that in this type of patient cohort, revision TKA using an RHK implant relieves pain more than it improves ability to function. The NexGen® RHK design can be regarded as a suitable option in complex revision TKA.

Cystic fibrosis (CF) is a rare, progressive, multi-organ genetic disease. Ivacaftor, a small-molecule CF transmembrane conductance regulator modulator, was the first medication to treat the underlying cause of CF. Since its approval, real-world clinical experience on the use of ivacaftor has been documented in large registries and smaller studies. Here, we systematically review data from real-world observational studies of ivacaftor treatment in people with CF (pwCF). Searches of MEDLINE and Embase identified 368 publications reporting real-world studies that enrolled six or more pwCF treated with ivacaftor published between January 2012 and September 2019. Overall, 75 publications providing data from 57 unique studies met inclusion criteria and were reviewed. Studies reporting within-group change for pwCF treated with ivacaftor consistently showed improvements in lung function, nutritional parameters, and patient-reported respiratory and sino-nasal symptoms. Benefits were evident as early as 1 month following ivacaftor initiation and were sustained over long-term follow-up. Decreases in pulmonary exacerbations, Pseudomonas aeruginosa prevalence, and healthcare resource utilization also were reported for up to 66 months following ivacaftor initiation. In studies comparing ivacaftor treatment to modulator untreated comparator groups, clinical benefits similarly were reported as were decreases in mortality, organ-transplantation, and CF-related complications. The safety profile of ivacaftor observed in these real-world studies was consistent with the well-established safety profile based on clinical trial data. Our systematic review of real-world studies shows ivacaftor treatment in pwCF results in highly consistent and sustained clinical benefit in both pulmonary and non-pulmonary outcomes across various geographies, study designs, patient characteristics, and follow-up durations, confirming and expanding upon evidence from clinical trials.

Abstract Background The FINE total knee was developed in Japan and clinical use began in 2001. It has unique design features, including an oblique 3o femorotibial joint line that reproduces anatomical geometry. Although 20 years have passed since the FINE knee was clinically used for the first time in Japan, a formal clinical evaluation including patient-reported and radiographic outcomes has not been undertaken. Methods A total of 175 consecutive primary cruciate-retaining (CR)-FINE total knee arthroplasties (TKAs) at our hospital between February 2015 and March 2017 were included in this study. Three years postoperatively, range of motion (ROM), Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS) and Forgotten Joint Score (FJS) were recorded and compared with preoperative scores. Radiographic analyses including mechanical alignment, component alignment, and incidence of radiolucent lines also were undertaken based on the radiographs 3 years postoperatively. Results One-hundred twenty-two knees (70%) were available for 3-year follow-up data using KOOS, except for the sports subscale. Postoperative KOOS-symptom, −pain and -ADL were > 85 points, but KOOS-sports, −QOL and FJS were less satisfactory. ROM, KSS and all the subscales of KOOS were significantly improved compared with preoperative scores. Postoperative mean FJS was 66 and was significantly correlated with all the subscales of KOOS, but not with postoperative ROM. Radiolucent lines ≧1 mm wide were detected in five knees (4.1%). There were no major complications needing revision surgeries. Conclusions Patient-reported outcomes (PROs) for symptoms, pain and ADL after the CR-FINE TKA were generally improved, but those for sports, QOL and FJS were improved less. The incidence of radiolucent lines was rare but detected around the femoral components. With the mid- to long-term follow-up, improvements of surgical technique will be necessary to achieve better PROs from patients receiving the FINE knee.
