Abstract — The International Society of Arthroplasty Registries (ISAR) Patient-Reported Outcome Measures (PROMs) Working Group have evaluated and recommended best practices in the selection, administration, and interpretation of PROMs for hip and knee arthroplasty registries. The 2 generic PROMs in common use are the Short Form health surveys (SF-36 or SF-12) and EuroQol 5-dimension (EQ-5D). The Working Group recommends that registries should choose specific PROMs that have been appropriately developed with good measurement properties for arthroplasty patients. The Working Group recommend the use of a 1-item pain question (“During the past 4 weeks, how would you describe the pain you usually have in your [right/left] [hip/knee]?”; response: none, very mild, mild, moderate, or severe) and a single-item satisfaction outcome (“How satisfied are you with your [right/left] [hip/knee] replacement?”; response: very unsatisfied, dissatisfied, neutral, satisfied, or very satisfied). Survey logistics include patient instructions, paper- and electronic-based data collection, reminders for follow-up, centralized as opposed to hospital-based follow-up, sample size, patient- or joint-specific evaluation, collection intervals, frequency of response, missing values, and factors in establishing a PROMs registry program. The Working Group recommends including age, sex, diagnosis at joint, general health status preoperatively, and joint pain and function score in case-mix adjustment models. Interpretation and statistical analysis should consider the absolute level of pain, function, and general health status as well as improvement, missing data, approaches to analysis and case-mix adjustment, minimal clinically important difference, and minimal detectable change. The Working Group recommends data collection immediately before and 1 year after surgery, a threshold of 60% for acceptable frequency of response, documentation of non-responders, and documentation of incomplete or missing data.

Background: Image-guided percutaneous ablation methods have proved effective for treatment of benign bone tumors and for palliation of metastases involving the bone. However, the role of these techniques is controversial and has to be better defined in the setting of palliative care. Methods: A systematic review of the existing data regarding minimally invasive techniques for the pain management of vertebral bone metastases was performed by experts of the European Palliative Care Research Network. Results: Only five papers were taken into consideration after performing rigorous screening according to inclusion and exclusion criteria (low number of patients, retrospective series, proceedings). Discussion: According to the present data a recommendation should be made to perform kiphoplasty in patients with vertebral tumors or metastases. However, the strength of this recommendation was based on one randomized controlled study. Several weaknesses and low quality of study design were observed with other techniques. Conclusion: Further randomized controlled trials are required to improve the strength of evidence available to suggest these procedures on large scale. Until then, the balance of evidence favors the use of these procedures in a small select cohort of patients with severe and disabling back pain refractory to medical therapy.

Background and purpose —There is solid evidence from animal experiments that parathyroid hormone (PTH) improves fracture healing. So far, only 3 papers on PTH and fracture repair in humans have been published. They suggest that PTH may enhance fracture healing, but the results do not appear to justify specific clinical recommendations. This study was carried out to determine whether teriparatide enhances fracture healing of proximal humerus fractures. Patients and methods —40 post-menopausal women with a proximal humerus fracture were randomized to either daily injections with 20 µg teriparatide (PTH 1-34 (Forteo)) for 4 weeks or control treatment. At randomization, the patients were asked to assess how their pain at rest and during activity (visual analog scale (VAS)) and also function (DASH score) had been prior to the fracture. At 7 weeks and again at 3 months, their current state was assessed and the tests were repeated, including radiographs. 2 radiologists performed a blind qualitative scoring of the callus at 7 weeks. Callus formation was arbitrarily classified as ”normal” or “better”. Results —39 patients completed the follow-up. The radiographic assessment showed a correct correlation, “better” in the teriparatide group and “normal” in the control group, in 21 of the 39 cases. There were no statistically significant differences in pain, in use of strong analgesics, or in function between the groups at the follow-up examinations. Interpretation —There were no radiographic signs of enhanced healing or improved clinical results in the group treated with teriparatide [ABSTRACT FROM AUTHOR]

Nail-patella syndrome is an autosomal dominant disorder characterized by nail dysplasia and skeletal anomaly. Some patients have been shown to have ultrastructural abnormalities of the glomerular basement membrane that result in nephrosis. However, little has been reported on the epidermal basement membrane in this condition. This paper reports 2 families with nail-patella syndrome. Direct sequencing analysis of LMX1B revealed that family 1 and family 2 were heterozygous for the mutations c.140-1G>C and c.326+1G>C, respectively. To evaluate the epidermal basement membrane zone, ultrastructural and immunohistochemical analyses were performed using skin specimens obtained from the dorsal thumb. Electron microscopy showed intact hemidesmosomes, lamina lucida, lamina densa, and anchoring fibrils. Immunofluorescence studies with antibodies against components of the epidermal basement membrane zone revealed a normal expression pattern among the components, including type IV collagen. These data suggest that nail dysplasia in patients with nail-patella syndrome is not caused by structural abnormalities of the epidermal basement membrane. [ABSTRACT FROM AUTHOR]

Introduction: Stereotactic radiosurgery (SRS) is a promising treatment option for patients with multiple brain metastases (BM). Recent technical advances have made LINAC based SRS a patient friendly technique, allowing for accurate patient positioning and a short treatment time. Since SRS is increasingly being used for patients with multiple BM, it remains essential that SRS be performed with the highest achievable quality in order to prevent unnecessary complications such as radionecrosis. The purpose of this article is to provide guidance for high-quality LINAC based SRS for patients with BM, with a focus on single isocenter non-coplanar volumetric modulated arc therapy (VMAT). Methods: The article is based on a consensus statement by the study coordinators and medical physicists of four trials which investigated whether patients with multiple BM are better palliated with SRS instead of whole brain radiotherapy (WBRT): A European trial (NCT02353000), two American trials and a Canadian CCTG lead intergroup trial (CE.7). This manuscript summarizes the quality assurance measures concerning imaging, planning and delivery. Results: To optimize the treatment, the interval between the planning-MRI (gadolinium contrast-enhanced, maximum slice thickness of 1.5 mm) and treatment should be kept as short as possible (< two weeks). The BM are contoured based on the planning-MRI, fused with the planning-CT. GTV-PTV margins are minimized or even avoided when possible. To maximize efficiency, the preferable technique is single isocenter (non-)coplanar VMAT, which delivers high doses to the target with maximal sparing of the organs at risk. The use of flattening filter free photon beams ensures a lower peripheral dose and shortens the treatment time. To bench mark SRS treatment plan quality, it is advisable to compare treatment plans between hospitals. Conclusion: This paper provides guidance for quality assurance and optimization of treatment delivery for LINAC-based radiosurgery for patients with multiple BM. [ABSTRACT FROM AUTHOR]

Background: Deformable image registration (DIR) is increasingly used in the field of radiation therapy (RT) to account for anatomical deformations. The aims of this paper are to describe the main applications of DIR in RT and discuss current DIR evaluation methods. Methods: Articles on DIR published from January 2000 to October 2018 were extracted from PubMed and Science Direct. Our search was restricted to articles that report data obtained from humans, were written in English, and address DIR methods for RT. A total of 207 articles were selected from among 2506 identified in the search process. Results: At planning, DIR is used for organ delineation using atlas-based segmentation, deformation-based planning target volume definition, functional planning and magnetic resonance imaging-based dose calculation. In image-guided RT, DIR is used for contour propagation and dose calculation on per-treatment imaging. DIR is also used to determine the accumulated dose from fraction to fraction in external beam RT and brachytherapy, both for dose reporting and adaptive RT. In the case of re-irradiation, DIR can be used to estimate the cumulated dose of the two irradiations. Finally, DIR can be used to predict toxicity in voxel-wise population analysis. However, the evaluation of DIR remains an open issue, especially when dealing with complex cases such as the disappearance of matter. To quantify DIR uncertainties, most evaluation methods are limited to geometry-based metrics. Software companies have now integrated DIR tools into treatment planning systems for clinical use, such as contour propagation and fraction dose accumulation. Conclusions: DIR is increasingly important in RT applications, from planning to toxicity prediction. DIR is routinely used to reduce the workload of contour propagation. However, its use for complex dosimetric applications must be carefully evaluated by combining quantitative and qualitative analyses. [ABSTRACT FROM AUTHOR]

Background: The treatment options for patients with therapy refractory metastatic colorectal cancer (mCRC) are sparse. TAS-102 (FTD/TPI) is a new oral anti-tumour agent composed of a nucleoside analogue, trifluridine, and a thymidine phosphorylase inhibitor, tipiracil, indicated for patients with mCRC who are refractory to standard therapies. This study summarizes published and unpublished experience with FTD/TPI in clinical practice settings. Patients and methods: The Medline/PubMed, Embase and Cochrane Library databases were searched to identify observational studies on FTD/TPI monotherapy for mCRC. Papers describing use of FTD/TPI monotherapy outside clinical trials in series of patients evaluable for effectiveness were eligible. The outcomes of interest were median progression free survival (mPFS), median overall survival (mOS) as well as mean PFS time restricted to six months (PFS6m) and mean OS time restricted to one year (OS1y). Results of the pooled analyses of observational studies were compared to the results of the Japanese phase II trial and the two phase III trials, RECOURSE and TERRA. Results: Seven published and two unpublished studies with 1008 patients from 64 centres were included for analysis. The pooled mPFS was 2.2 months (95% CI 2.1 to 2.3 months), and the pooled mOS was 6.6 months (95% CI 6.1 to 7.1 months). PFS6m was 2.9 months (95% CI 2.6 to 3.1 months) and OS1y was 6.8 (95% CI 6.0 to 7.5) months. While these results all reflect RECOURSE, the pooled mOS is lower than in the phase II trial and the OS1y is inferior to both the phase II trial and TERRA. Conclusion: This systematic review and a meta-analysis indicates that in real life settings, the survival benefit of FTD/TPI monotherapy in patients with therapy refractory mCRC reflects the outcomes in RECOURSE but is inferior to outcomes in the two Asian efficacy trials. TAS 102 (Lonsurf) is an oral fixed dose combination of trifluridine (FTD) and tipiracil (TPI) indicated as salvage-line treatment in patients with therapy refractory metastatic colorectal cancer (mCRC). A Japanese phase II trial and two phase III trials, RECOURSE and TERRA, demonstrated that FTD/TPI prolonged overall survival. This systematic review and meta-analysis of real life data from 64 sites indicates that the effectiveness in daily clinical practice settings of FTD/TPI monotherapy in late stage mCRC reflects the outcomes in RECOURCE but is inferior to the outcomes in the Japanese phase II trial and TERRA.

Background: Academic detailing (AD) is a defined form of educational outreach that can be deployed to intrinsically motivate practitioners towards improving quality of care. This paper describes the design of the ADVOCATE Field Studies. This proof of concept study aims to evaluate the feasibility, acceptability and usefulness of AD, reinforced with feedback information to promote prevention-oriented, patient-centred and evidence-based oral healthcare delivery by general dental practitioners (GDPs). Methods: Six groups of GDPs will be recruited; two groups of six to eight GDPs in each of three countries - the Netherlands, Germany and Denmark. GDPs will meet for four Academic Detailing Group (ADG) meetings for open discussions using comparative feedback data to stimulate debate about their dental practice performance and care delivery. Group meetings will be moderated using the AD methodology. Qualitative data will be collected through focus group interviews, an online discussion forum, field notes and debriefs of ADG meetings and analysed by conventional content analysis using MaxQDA software. Discussion: The results of the study will provide novel information on the feasibility, perceived acceptability and usefulness of AD and feedback data for GDPs to improve oral healthcare delivery.

Objective: When dealing with the impact of malocclusion on self-esteem, the terms global and dental self-esteem are sometimes used. Although these terms are related to one another, they do not depict the same concept. The aims of this paper were to explore if the two forms of self-esteem are distinguishable, to find out if they represent different factors, and to investigate how they are related to malocclusion. Materials and methods: A sample consisting of 150 adolescents, aged 13 years, completed self-assessed measures of Dental and Global Self-Esteem. Orthodontic treatment need for each individual was assessed by the Dental Health Component of the Index of Orthodontic Treatment Need (IOTN-DHC). Data were analysed by factor analyses and a 5 (IOTN-DHC grades) by 2 (global vs. dental self-esteem) ANOVA, with the IOTN-DHC grades as the independent and self-esteem (repeated measure) as the dependent variables. Results: The factor analyses showed that the two forms of self-esteem, based on the measures, are distinguishable. More importantly, the results of the ANOVA revealed that Dental and Global Self-Esteem are differentially related to IOTN-DHC. Specifically, Dental Self-Esteem varied across IOTN-DHC scale while Global Self-Esteem did not. There was no effect of gender. Conclusions: Dental self-esteem is related to malocclusion while global self-esteem is not. These findings have implications in areas where the predictive power of dental self-esteem needs to be considered. [ABSTRACT FROM AUTHOR]

Background: Cancer and cancer treatments may impact the brain through several pathways leading to cognitive impairment. Neuroimaging evidence has begun to elucidate the neurobiological underpinnings of cancer-related cognitive impairment. The aim of this paper was to systematically review available literature on structural brain alterations following adult non-central nervous system (CNS) cancers and associated treatments. Methods: This review followed PRISMA guidelines and was registered in PROSPERO (ID#107387). Comprehensive searches were conducted in June 2018 using PubMed and Web of Science. Inclusion criteria were English peer-reviewed journal articles of formal, controlled studies that examined structural neuroimaging outcomes in adult non-CNS cancer patients and survivors. Selected articles were assessed for quality and risk of bias using the National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Results: Thirty-six publications of prospective and cross-sectional studies met inclusion criteria and were included. Structural brain alterations following cancer and its treatment were reported in a majority of the publications as evidenced by reduced global and local gray matter volumes, impaired white matter microstructural integrity, and brain network alterations. Structural alterations were most often evident when cancer-treated groups were compared with healthy controls, and more subtle when compared with cancer controls. Regarding the existence of pretreatment impairments, the evidence was equivocal. There was significant between-study heterogeneity in imaging analytical approaches and use of statistical adjustments. Over half reported associations with cognitive outcomes, though regions and associated cognitive domains were heterogeneous. Conclusions: Structural brain alterations following cancer and cancer treatments were reported in a majority of the reviewed studies. However, the extent of observed alterations depended on the choice of comparison groups. Methodological issues exist that will need to be addressed systematically to ensure the validity of findings. Large-scale prospective studies with extended assessment points are warranted to replicate and build upon initial findings. [ABSTRACT FROM AUTHOR]

Aim: The aim of this article is to review the literature on the use of antimicrobial additives in glass-ionomer dental cements. Method: An electronic search between 1987 and the end of 2017 was performed using PubMed, Web of Science and Google search engines with the terms glass-ionomer, glass polyalkenoate, antibacterial and antimicrobial as the key words. The search was refined by excluding the majority of references concerned with cement antimicrobial properties only. Extra papers already known to the authors were added to those considered. Results: A total of 92 relevant articles have been cited in the review of which 55 are specifically concerned with the enhancement of antibacterial properties of glass-ionomers, both conventional and resin-modified, with additives. In addition, information is included on the uses of glass-ionomers and the biological properties of the antibacterial additives employed. There are several reports that show that additives are typically released by diffusion, and that a high proportion is usually left behind, trapped in the cement. Additives generally increase setting times of cements, and reduce mechanical properties. However, smaller amounts of additive have only slight effects and the longer-term durability of cements appears unaffected. Conclusion: Modified glass-ionomer cements seem to be acceptable for clinical use, especially in the Atraumatic Restorative Treatment (ART) technique. [ABSTRACT FROM AUTHOR]

Objective. The purpose of this systematic review and meta-analysis was to evaluate the reliability of the Carisolv system with respect to drilling regarding the full removal of decayed hard tissues in primary dentition. A systematic review of the literature was conducted to identify controlled trails, randomized controlled trials and clinical trials that compared the Carisolv system to the traditional mechanical caries removal in the primary dentition. Materials and methods. The main relevant databases were searched: MEDLINE via PUBMED, Web of Science and SCOPUS. Complete caries removal, length of working time and need of local anesthesia were the outcomes evaluated. Results. A total of 195 studies were identified and complete analysis of 28 studies was performed; finally, 10 papers were included. The trials included involved a total of 348 patients for 532 treated teeth. There was no significant difference in terms of clinical efficacy between the Carisolv and the rotary instrument (z = 0.68, p = 0.50), whereas the treatment with Carisolv was significantly longer in terms of time with respect to the rotary instruments (z = 10.49, p < 0.01). The chemo mechanical technique reduces the need for local anesthesia, with a difference between two types of treatment near to statistical significance (z = 1.91 p = 0.06). Conclusions. This systematic review indicates that the clinical efficacy of chemo-mechanical removal with Carisolv seems as reliable as the rotary instruments. However, the results should be interpreted cautiously due to the heterogeneity among study designs and to the shortage of available data. Further large-scale, well-designed randomized controlled trials are needed. [ABSTRACT FROM AUTHOR]

Background. Although families of children with cancer and other serious medical conditions have documented psychosocial needs, the systematic identification of needs and delivery of evidence-based care remain challenges. Screening for multifaceted family psychosocial risk is a means by which psychosocial treatment needs for pediatric patients and their families can be identified in an effective and inclusive manner. Material and methods. The Pediatric Psychosocial Preventative Health Model (PPPHM) is a model that can guide systematic assessment of family psychosocial risk. The Psychosocial Assessment Tool (PAT) is a brief parent report screener of psychosocial risk based on the PPPHM that can be used for families of infants through adolescents. The PPPHM and the PAT are described in this paper, along with a summary of data supporting systematic risk assessment. Results. The PPPHM outlines three tiers of family psychosocial risk - Universal (low), Targeted (medium), and Clinical (high). The PAT is a validated measure of psychosocial risk. Scores on the PAT, derived from multiple sites and disease conditions, map on to the PPPHM with indications that one-half to two-thirds of families score at the Universal level of risk based on the PAT. Conclusion. The PAT is a unique screener of psychosocial risk, both in terms of its breadth and underlying model (PPPHM), and its length and format. As an example of a means by which families can be screened early in the treatment process, PAT scores and corresponding PPPHM levels can provide direction for the delivery of evidence-based psychosocial care.

Glass-ionomer cements are used for a variety of tooth-repair functions in clinical dentistry. They are formed by reaction of a basic glass powder with a solution of polymeric water-soluble acid, usually polyacrylic acid. After the initial neutralization reaction, by which the cement hardens, various maturation reactions occur. Changes induced by these maturation reactions are identified as: increase in strength; reduction in plasticity; improvement in opacity; and increase in proportion of tightly bound water. In addition, in contact with the tooth, an ion-exchange interfacial layer is gradually formed. This is mechanically strong and chemically-resistant. These changes are described in the current paper, which reviews the extent to which they occur, and reports what is know about the chemistry that underlies them. Processes involving slow diffusion of various ions and of water through the set cement bring about these changes. They include a secondary setting reaction to form a phosphate-based phase, binding of water to co-ordination sites around metal cations and to a hydration sheath around the polymer molecules, and possibly reaction of water with glass particle surfaces to form silanol groups. Evidence from a wide range of literature sources is used to be build up a detailed picture of the chemistry of the maturation processes, and gaps in our understanding are highlighted. The article concludes that, given the importance of glass-ionomers in contemporary dentistry, it is important to know the extent to which such maturation processes occur in current cement formulations, and also to determine how rapidly they take place.

Gorlin syndrome comprises multiple basal cell carcinomas (BCCs), basal cell naevi (BCNs), odontogenic keratocysts, skeletal abnormalities and other features (1). Identification of the PTCH1 gene as the candidate gene for Gorlin syndrome demonstrated that activation of the Hedgehog (Hh) pathway is the key driver in the physiology and pathology of BCC formation (2). Gorlin syndrome has been linked to germline mutations of various members of the Hh pathway, including mainly PTCH1 and also PTCH2 and SUFU; however, to date, SMO germline mutations have not been described. Recently, a case of Gorlin syndrome type 1 mosaicism presented a somatic mutation of SMO L412F (3). This mutation has been described as oncogenic, conferring constitutive activation of the Hh pathway (4). This paper describes a second case of Gorlin syndrome mosaicism with the same SMO L412F mutation observed in affected skin. A detailed molecular assessment of multiple BCNs and BCCs was performed to analyse the oncogenic steps of BCC formation in this patient. [ABSTRACT FROM AUTHOR]

Objective. A major aspect in evaluating the quality of dental materials is their physical properties. Their properties should be a best fit of the ones of dental hard tissues. Manufacturers give data sheets for each material. The properties listed are characterized by a specific value. This assumes (but does not prove) that there is no direction dependence of the properties. However, dental enamel has direction-dependent properties which additionally vary with location in the tooth. The aim of this paper is to show the local direction dependence of physical properties like the elastic modulus or the thermal expansion in dental hard tissues. With this knowledge the 'perfect filling/dental material' could be characterized. Materials and method. Enamel sections of ∼400-500 μm thickness have been cut with a diamond saw from labial/buccal to palatal/lingual (canine, premolar and molar) and parallel to labial (incisor). Crystallite arrangements have been measured in over 400 data points on all types of teeth with x-ray scattering techniques, known from materials science. Results. X-ray scattering measurements show impressively that dental enamel has a strong direction dependence of its physical properties which also varies with location within the tooth. Dental materials possess only little or no property direction dependence. Therefore, a mismatch was found between enamel and dental materials properties. Conclusion. Since dental materials should possess equal (direction depending) properties, worthwhile properties could be characterized by transferring the directional properties of enamel into a property 'wish list' which future dental materials should fulfil. Hereby the 'perfect dental material' can be characterized. [ABSTRACT FROM AUTHOR]

The article focuses on the importance of accurate prevalence knowledge in clinical decision-making, emphasizing the potential cognitive bias and errors that may arise from over- or underestimating the prevalence of clinical phenomena. Topics include the sources of knowledge on prevalence, the fundamental classification of proximal humeral fractures into minimally displaced and displaced categories, and the misleading statement regarding the prevalence of minimally displaced fractures.

Electrochemotherapy is now in routine clinical use to treat cutaneous metastases of any histology, and is listed in national and international guidelines for cutaneous metastases and primary skin cancer. Electrochemotherapy is used by dermatologists, surgeons, and oncologists, and for different degrees and manifestations of metastases to skin and primary skin tumours not amenable to surgery. This treatment utilises electric pulses to permeabilize cell membranes in tumours, thus allowing a dramatic increase of the cytotoxicity of anti-cancer agents. Response rates, often after only one treatment, are very high across all tumour types. The most frequent indications are cutaneous metastases from malignant melanoma and breast cancer. In 2006, standard operating procedures (SOPs) were written for this novel technology, greatly facilitating introduction and dissemination of the therapy. Since then considerable experience has been obtained treating a wider range of tumour histologies and increasing size of tumours which was not originally thought possible. A pan-European expert panel drawn from a range of disciplines from dermatology, general surgery, head and neck surgery, plastic surgery, and oncology met to form a consensus opinion to update the SOPs based on the experience obtained. This paper contains these updated recommendations for indications for electrochemotherapy, pretreatment information and evaluation, treatment choices, as well as follow-up. [ABSTRACT FROM AUTHOR]

Prostanoids, including prostaglandins (PGs) and thromboxane A2 (TXA2), are a family of lipid-derived autacoids that modulate many physiological systems and pathological contexts. Prostanoids are generated by sequential metabolism of arachidonic acid, catalysed by cyclo-oxygenase, to PGH2, which is then converted to PGD2, PGE2, PGF2α, PGI2 and TXA2, catalysed by their specific synthases. Recent evidence suggests that prostanoids play a role in regulating hair growth. The PGF2α analogue is Food and Drug Administrationapproved in the US and routinely used to enhance the growth of human eyelashes. PGE2 is reported to protect from radiation-induced hair loss in mice. Conversely, PGD2 inhibits hair growth. This paper reviews the metabolism of prostanoids and the expression pattern of prostanoid receptors in hair follicles, focussing on their different and opposing effects on hair growth and the underlying mechanisms. This has potential clinical relevance in the treatment and prevention of hair disorders. [ABSTRACT FROM AUTHOR]

Background and purpose - There is debate as to the relative merits of unicompartmental and total knee arthroplasty (UKA, TKA). Although the designer surgeons have achieved good results with the Oxford UKA there is concern over the reproducibility of these outcomes. Therefore, we evaluated published long-term outcomes of the Oxford Phase 3 UKA. Patients and methods - We searched databases to identify studies reporting ≥10 year outcomes of the medial Oxford Phase 3 UKA. Revision, non-revision, and re-operation rates were calculated per 100 component years (% pa). Results - 15 studies with 8,658 knees were included. The annual revision rate was 0.74% pa (95% CI 0.67--0.81, n = 8,406) corresponding to a 10-year survival of 93% and 15-year survival of 89%. The non-revision re-operation rate was 0.19% pa (95% CI 0.13--0.25, n = 3,482). The re-operation rate was 0.89% pa (95% CI 0.77--1.02, n = 3,482). The most common causes of revision were lateral disease progression (1.42%), aseptic loosening (1.25%), bearing dislocation (0.58%), and pain (0.57%) (n = 8,658). Average OKS scores were 40 at 10 years (n = 3,417). The incidence of medical complications was 0.83% (n = 1,443). Interpretation - Very good outcomes were achieved by both designer and non-designer surgeons. The PROMs, medical complication rate, and non-revision re-operation rate were better than those found in meta-analyses and publications for TKA but the revision rate was higher. However, if failure is considered to be all re-operations and not just revisions, then the failure rate of UKA was less than that of TKA. [ABSTRACT FROM AUTHOR]

An editorial is presented on studies aiming to answer the remaining questions around dual mobility cups. Topics include the dual mobility cups (DMCs) came onto the market to reduce the risk of dislocation after total hip arthroplasty, and the spherical liner in a DMC encloses the metal femoral head and articulates with a thin metal shell which is fixed to the acetabular bone.

Background:The introduction of adjuvant chemotherapy following surgery for early breast cancer (BC) and its integration into routine clinical practice has consistently improved clinical outcomes. Since the addition of other agents to the contemporary standard of care containing an anthracycline, cyclophosphamide and a taxane has not lead to further prolongation of survival, subsequent efforts concentrated on escalating the administered doses and reducing the time interval between chemotherapy cycles. These strategies have been extensively evaluated in randomized trials and dose dense chemotherapy is now recommended by clinical practice guidelines. Method:Eligible trials were identified by searching the EMBASE, Pubmed, Scopus and Cochrane Library databases, as well as conference papers. The findings, shortcomings and impact of these studies are presented and critically discussed. Results:Although a large number of randomized trials has established the value of adjuvant chemotherapy, important questions remain unanswered. Ongoing research focuses on omitting treatment in good risk patients, identifying patients most likely to benefit from a dose dense approach and on administering personalized doses such as in tailored dose chemotherapy. Conclusions:Adjuvant chemotherapy for early BC is an evolving art. Further optimizations could potentially improve outcomes for a patient subset and spare others from unnecessary treatment-related toxicity. [ABSTRACT FROM PUBLISHER]

Objective: This study investigated the presence of Enterococcus faecalis in primary teeth with primary root canal infections and related to the possible failure of pulpectomy outcome after 36 months.Material and Methods: Root canal samples were obtained from 25 out of 244 patients using the sterile paper cone method. The identification of E. faecalis was done with culture and molecular tests using species-specific 16S rRNA gene-based polymerase chain reaction (PCR). After 36 months, the pulpectomy outcome was evaluated.Results: Enterococcus faecalis was found in five (20%) samples, and dental caries were the cause of primary infection in all of them. Pulpectomy outcome was evaluated only in teeth that completed the entire clinical protocol and were followed up to 36 months (n = 8). From these, 75% (n = 6) were successful and 25% (n = 2) failed. E. faecalis was present in 50% of both successful and failed cases.Conclusions: Enterococcus faecalis was not related to the failure of endodontic treatment of primary teeth. [ABSTRACT FROM AUTHOR]

Background and purpose — The use of uncemented fixation in total hip arthroplasty (THA) is increasing. Registry studies have indicated an increased risk of revision of uncemented implants due to early periprosthetic femoral fracture. In this paper, we describe the incidence and predisposing factors for intraoperative and early postoperative (≤90 days) periprosthetic femoral fractures after cemented and uncemented THA. Patients and methods — This was a prospective observational study in 8 Danish high-volume centers from February 2010 to November 2013. We used the 90-day follow-up from the Danish National Patient Registry and patient records. We obtained intraoperative information from the Danish Hip Arthroplasty Registry and from surgical notes. Results — Of 7,169 primary consecutive THAs, 5,482 (77%) were performed using uncemented femoral components. The total incidence of periprosthetic femoral fractures≤90 days postoperatively was 2.1% (n = 150). 70 fractures were detected intraoperatively (46 required osteosynthesis). 51 postoperatively detected fractures occurred without trauma (42 of which were reoperated) and 29 were postoperative fall-related fractures (27 of which were reoperated). 134 fractures (2.4%) were found in uncemented femoral components and 16 (0.9%) were found in cemented femoral components (p < 0.001). Uncemented femoral stem (relative risk (RR) = 4.1, 95% CI: 2.3–7.2), medically treated osteoporosis (RR =2.8, CI: 1.6–4.8), female sex (RR =1.6, CI: 1.1–2.2), and age (RR =1.4 per 10 years, CI: 1.2–1.6) were associated with increased risk of periprosthetic femoral fracture when analyzed using multivariable regression analysis. Interpretation — Uncemented femoral components were associated with an increased risk of early periprosthetic femoral fractures, especially in elderly, female, and osteoporotic patients.

Background and purpose — In 3 papers in Acta Orthopaedica 10 years ago, we described that platelet-rich plasma (PRP) improves tendon healing in a rat Achilles transection model. Later, we found that microtrauma has similar effects, probably acting via inflammation. This raised the suspicion that the effect ascribed to growth factors within PRP could instead be due to unspecific influences on inflammation. While testing this hypothesis, we noted that the effect seemed to be related to the microbiota. Material and methods — We tried to reproduce our old findings with local injection of PRP 6 h after tendon transection, followed by mechanical testing after 11 days. This failed. After fruitless variations in PRP production protocols, leukocyte concentration, and physical activity, we finally tried rats carrying potentially pathogenic bacteria. In all, 242 rats were used. Results — In 4 consecutive experiments on pathogen-free rats, no effect of PRP on healing was found. In contrast, apparently healthy rats carrying Staphylococcus aureus showed increased strength of the healing tendon after PRP treatment. These rats had higher levels of cytotoxic T-cells in their spleens. Interpretation — The failure to reproduce older experiments in clean rats was striking, and the difference in response between these and Staphylococcus-carrying rats suggests that the PRP effect is dependent on the immune status. PRP functions may be more complex than just the release of growth factors. Extrapolation from our previous findings with PRP to the situation in humans therefore becomes even more uncertain.

Background:The clinical feasibility of using pseudo-computed tomography (pCT) images derived from magnetic resonance (MR) images for external bean radiation therapy (EBRT) planning for prostate cancer patients has been well demonstrated. This paper investigates the feasibility of applying an MR-derived, pCT planning approach to additional types of cancer in the pelvis. Material and methods:Fifteen patients (five prostate cancer patients, five rectal cancer patients, and five gynecological cancer patients) receiving EBRT at Turku University Hospital (Turku, Finland) were included in the study. Images from an MRCAT (Magnetic Resonance for Calculating ATtenuation, Philips, Vantaa, Finland) pCT method were generated as a part of a clinical MR-simulation procedure. Dose calculation accuracy was assessed by comparing the pCT-based calculation with a CT-based calculation. In addition, the degree of geometric accuracy was studied. Results:The median relative difference of PTV mean dose between CT and pCT images was within 0.8% for all tumor types. When assessing the tumor site-specific accuracy, the median [range] relative dose differences to the PTV mean were 0.7 [−0.11;1.05]% for the prostate cases, 0.3 [−0.25;0.57]% for the rectal cases, and 0.09 [−0.69;0.25]% for the gynecological cancer cases. System-induced geometric distortion was measured to be less than 1 mm for all PTV volumes and the effect on the PTV median dose was less than 0.1%. Conclusions:According to the comparison, using pCT for clinical EBRT planning and dose calculation in the three investigated types of pelvic cancers is feasible. Further studies are required to demonstrate the applicability to a larger cohort of patients. [ABSTRACT FROM PUBLISHER]

Background and purpose — The use of a cemented cup together with an uncemented stem in total hip arthroplasty (THA) has become popular in Norway and Sweden during the last decade. The results of this prosthetic concept, reverse hybrid THA, have been sparsely described. The Nordic Arthroplasty Register Association (NARA) has already published 2 papers describing results of reverse hybrid THAs in different age groups. Based on data collected over 2 additional years, we wanted to perform in depth analyses of not only the reverse hybrid concept but also of the different cup/stem combinations used. Patients and methods — From the NARA, we extracted data on reverse hybrid THAs from January 1, 2000 until December 31, 2013. 38,415 such hips were studied and compared with cemented THAs. The Kaplan-Meier method and Cox regression analyses were used to estimate the prosthesis survival and the relative risk of revision. The main endpoint was revision for any reason. We also performed specific analyses regarding the different reasons for revision and analyses regarding the cup/stem combinations used in more than 500 cases. Results — We found a higher rate of revision for reverse hybrids than for cemented THAs, with an adjusted relative risk of revision (RR) of 1.4 (95% CI: 1.3–1.5). At 10 years, the survival rate was 94% (CI: 94–95) for cemented THAs and 92% (95% CI: 92–93) for reverse hybrids. The results for the reverse hybrid THAs were inferior to those for cemented THAs in patients aged 55 years or more (RR =1.1, CI: 1.0–1.3; p < 0.05). We found a higher rate of early revision due to periprosthetic femoral fracture for reverse hybrids than for cemented THAs in patients aged 55 years or more (RR =3.1, CI: 2.2–4.5; p < 0.001). Interpretation — Reverse hybrid THAs had a slightly higher rate of revision than cemented THAs in patients aged 55 or more. The difference in survival was mainly caused by a higher incidence of early revision due to periprosthetic femoral fracture in the reversed hybrid THAs. [ABSTRACT FROM PUBLISHER]

Objective: Concerns over adverse effects of mercury released from dental amalgam sometimes lead patients to request removal of their amalgam restorations. Several studies report improvement of subjective health after removal of amalgam restorations, but the mechanisms are unclear. The aim of this paper is to present data on long term changes in intensity of health complaints after amalgam removal in a group of patients with health complaints self-attributed to dental amalgam. Data from the five years follow-up in a clinical trial are presented and related to potential determinants of change.Materials and Methods: Patients previously referred to a specialty unit for health complaints attributed to amalgam restorations were included in the study. The 20 participants who were allocated to the treatment group had all amalgam restorations removed and replaced with other dental restorative materials. Intensity of health complaints was calculated from questionnaire data and personality variables were measured by MMPI-2.Results: At the follow-up five years after the amalgam removal was completed, intensity of general health complaints was significantly reduced (p=.001), but the symptom load was still high. The reduction was significantly correlated with concentration of mercury in urine at pre-treatment. There were no significant correlations with personality variables.Conclusions: Removal of amalgam restorations was followed by a long term reduction of general health complaints, which was associated with mercury concentration in urine before amalgam removal. Additional studies are needed to confirm the potential mechanisms for the observed reduction. [ABSTRACT FROM AUTHOR]

Pruritus occurs frequently in the elderly population, but it has not been fully defined and its precise prevalence is unknown. Putative causes of pruritus are numerous and patients' quality of life can be greatly reduced. In the absence of any specific cause, a diagnosis of senile pruritus is proposed, suggesting that itch is secondary to ageing. However, the relationship of pruritus with skin ageing and/or neuronal ageing and/or immune ageing is poorly understood. Many treatments have been reported, but are poorly effective. This paper reviews the literature on senile pruritus, in order to improve understanding of this condition and to enable improved diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Background:The main treatment for non-metastatic rectal cancer (RC) is surgical resection. Late adverse effects that are highly prevalent and negatively impact patients’ symptom burden and quality of life are: bowel-, urological and sexual dysfunctions; psychological distress; fear of recurrence. Patients and clinicians have requested a more patient-centred follow-up, balancing the focus on detection of recurrence, and physiological and psychological late adverse effects. The current follow-up program primarily focuses on detection of recurrence, with less attention on late adverse effects. As a consequence, the randomized controlled trial Follow-up after Rectal Cancer (FURCA) has been launched, testing the effect of a new patient-led, follow-up program. The aim of this paper is to describe the methodology used in the FURCA study and to report results from the development of the patient-led, follow-up program. Adult patients, treated with curative intent for primary adenocarcinoma in the rectum are included from four Danish centers. Material and methods:Patients are randomized into an intervention group, receiving standardized education and access to self-referral to an assigned project nurse, or a control group following the current follow-up program with routine medicals. The primary outcomes are symptom burden and quality of life, measured by the Functional Assessment of Cancer Therapy – Colorectal (FACT-C) questionnaire. Other outcome and demographic data are collected as patient-reported measures and register-based data. Results from developing the intervention:The education program is based on data from two focus group interviews and the feedback from experts. An algorithm is developed in order to qualify the research nurses’ responses to patients’ self-referral. Discussion and perspectives:The results of the FURCA study will strengthen the evidence base for RC follow-up, and qualify the ongoing transformation in cancer follow-up programs.

Background:Survivorship care plans (SCPs) are internationally endorsed as an important tool to enhance post-treatment survivorship care. To support broad implementation of SCPs, we investigated survivors’ preferences regarding SCPs. Material and methods:The study was conducted at a comprehensive cancer center. Eligible patients from 10 clinical services, generally up to 12 months following end of treatment (EOT) were approached in clinics or via telephone. A purpose-designed survey assessed survivors’ intended use of a SCP and preferences regarding format and content. Intended minimum sample size of 200. Results:Two hundred and thirty surveys were returned (response rate 68%). Of the 230 participants, over 55% had completed treatment within six months, 35% between six and 12 months, and 10% were receiving ongoing treatments. Most (82%) had not received a SCP and more than one third (42%) reported receiving no information resources at EOT. Almost all (98%) desired further information. Most common information elements desired in a SCP: ‘list of symptoms to watch out for and report’ (76%), ‘summary of treatment received’ (70%) and ‘things I can do to look after myself’ (67%). Most common suggested uses were as: ‘a record of cancer treatment’ (63%), ‘a reminder of things to do to look after myself ’ (57%) and ‘to help me understand my cancer experience’ (56%). Over half (52%) would share the information with their general practitioner. Most indicated preference for paper-based SCPs (91%). There was support for both brief (36%) and detailed versions (42%). Over half requested the information be delivered in a face-to-face discussion with a health professional. Regular telephone support from the treating health care team was most commonly suggested as an additional service to support survivors after EOT. Conclusions:Although similar to international findings, results suggest alternate ways of providing the information that survivors desire. Most desired SCP elements have been defined. A flexible approach to SCP interventions is justified. [ABSTRACT FROM PUBLISHER]

The Danish Prostate Cancer Registry and a local Norwegian registry at Innlandet Hospital Trust are two exceptions, converting SNOMED coding or structured digital formulas in the clinical workflow to registry data [[5]]. The medical record has during ages served as the main documentation of medical practice and is still mandatory for practicing doctors in most countries. [Extracted from the article]

Objective: This is a rapid systematic review concerning taste alterations in 27,687 individuals infected with SARS-CoV-2, published in the worldwide literature. Material and methods: Of the 485 articles recovered, 67 eligible studies (27,687 confirmed COVID-19 cases) were included in this analysis. We analysed the prevalence of the taste alterations in patients considering the country of origin of the studies. Results: The results show strong important differences in the overall reported prevalence of taste alterations among the different countries (from 11% of Korea to 88.8% of Belgium). Conclusions: These data highlight that there is a different geographical distribution of taste alterations in COVID-19 patients. Gustatory dysfunction seems to be an understudied symptom of COVID-19 and this may explain the inconsistencies of diagnostic criteria for COVID-19 case definition. Furthermore, this diagnostic underestimation can lead to an increased risk of contagion for the whole population and for the working classes most at risk, including the dental one.

Background and purpose — Custom triflange acetabular components (CTACs) are suggested as good solutions for large acetabular defects in revision total hip arthroplasty. However, high complication rates have been reported and most studies are of limited quality. This prospective study evaluates the performance of a CTAC in patients with large acetabular defects including pelvic discontinuity. Patients and methods — Prospectively collected data of 49 consecutive patients (50 hips), who underwent an acetabular revision with a CTAC were analyzed. Follow-up (FU) was 2 years. The median age of the patients was 68 years (41–89) and 41 were women. Primary outcomes were re-revision of the CTAC and differences between the modified Oxford Hip Score (mOHS) preoperatively and at 2-year follow-up. Secondary outcomes included several patient-reported outcomes (PROMs), radiological results, complications, and a comparison between hips with and without pelvic discontinuity (PD). Results — 1 patient (1 hip) was lost to the 2-year FU. No CTAC needed re-revision. The preoperative and 2-year FU mOHS were available in 40 hips and improved statistically significantly. All of the other secondary outcomes improved over time. 5 hips (of 45 with radiological 2-year FU) had loosening of screws. 8 hips had complications, including 3 persistent wound leakage, 3 pelvic fractures, and 1 dislocation. The mOHS and complication rate were similar in hips with and without PD. Interpretation — Reconstruction of large acetabular defects with and without PD with this CTAC showed good improvement in patient-reported daily functioning, high patient-reported satisfaction, few complications, and no re-revisions at 2-year FU.

Background:Cancer in a child is associated with a significant impact on parental employment. We assessed the proportions of parents of survivors and bereaved parents working and reporting sick leave five years after end of successful treatment (ST)/child’s death (T7) compared with one year after end of ST/child’s death (T6) and the association between partial post-traumatic stress disorder (PTSD) and work situation and sick leave at T7. Participants and procedure:The sample included 152 parents of survivors (77 mothers, 75 fathers) and 42 bereaved parents (22 mothers, 20 fathers) of children diagnosed with cancer in Sweden. Results:The proportions of parents working or reporting sick leave did not differ among mothers and fathers of survivors (92% vs. 96% working, 20% vs. 18% on sick leave) or among bereaved mothers and fathers (91% vs. 90% working, 14% vs. 20% on sick leave) at T7. There was no change from T6 to T7 in the proportion of fathers working (fathers of survivors 91% vs. 96%, bereaved fathers 95% vs. 90%). Although more mothers of survivors (92% vs. 82%) and bereaved mothers (91% vs. 77%) worked at T7 than at T6, this increase was not significant. Fewer bereaved mothers reported sick leave at T7 than at T6 (14% vs. 59%, p < 0.05). Although more fathers reported sick leave at T7 than at T6 (fathers of survivors 18% vs. 8%, bereaved fathers 20% vs. 15%), this was not significant. Partial PTSD was not associated with parents’ work situation or sick leave at T7. Conclusion:Results suggest little adverse effect on work situation and sick leave among parents of survivors and bereaved parents five years after end of ST/child’s death from cancer. However, the pattern of change observed differed between parents, which could potentially indicate possible delayed consequences for fathers not captured in the present paper.

The International Atomic Energy Agency (IAEA) has a long tradition of supporting development of methodologies for national networks providing quality audits in radiotherapy. A series of co-ordinated research projects (CRPs) has been conducted by the IAEA since 1995 assisting national external audit groups developing national audit programs. The CRP ‘Development of Quality Audits for Radiotherapy Dosimetry for Complex Treatment Techniques’ was conducted in 2009–2012 as an extension of previously developed audit programs.Material and methods.The CRP work described in this paper focused on developing and testing two steps of dosimetry audit: verification of heterogeneity corrections, and treatment planning system (TPS) modeling of small MLC fields, which are important for the initial stages of complex radiation treatments, such as IMRT. The project involved development of a new solid slab phantom with heterogeneities containing special measurement inserts for thermoluminescent dosimeters (TLD) and radiochromic films. The phantom and the audit methodology has been developed at the IAEA and tested in multi-center studies involving the CRP participants.Results.The results of multi-center testing of methodology for two steps of dosimetry audit show that the design of audit procedures is adequate and the methodology is feasible for meeting the audit objectives. A total of 97% TLD results in heterogeneity situations obtained in the study were within 3% and all results within 5% agreement with the TPS predicted doses. In contrast, only 64% small beam profiles were within 3 mm agreement between the TPS calculated and film measured doses. Film dosimetry results have highlighted some limitations in TPS modeling of small beam profiles in the direction of MLC leave movements.Discussion.Through multi-center testing, any challenges or difficulties in the proposed audit methodology were identified, and the methodology improved. Using the experience of these studies, the participants could incorporate the auditing procedures in their national programs. [ABSTRACT FROM PUBLISHER]

are the most common type of elbow fracture in children. A small proportion of them are flexion-type fractures. We analyzed their current incidence, injury history, clinical and radiographic findings, treatment, and outcomes. Patients and methods -- We performed a population-based study, including all children < 16 years of age. Radiographs were re-analyzed to include only flexion-type supracondylar fractures. Medical records were reviewed and outcomes were evaluated at a mean of 9 years after the injury. In addition, we performed a systematic literature review of all papers published on the topic since 1990 and compared the results with the findings of the current study. Results -- During the study period, the rate of flexion-type fractures was 1.2% (7 out of 606 supracondylar humeral fractures). The mean annual incidence was 0.8 per 105. 4 fractures were multidirectionally unstable, according to the Gartland- Wilkins classification. All but 1 were operatively treated. Reduced range of motion, changed carrying angle, and ulnar nerve irritation were the most frequent short-term complications. Finally, in the long-term follow-up, mean carrying angle was 50% more in injured elbows (21°) than in uninjured elbows (14°). 4 patients of the 7 achieved a satisfactory long-term outcome according to Flynn's criteria. Interpretation -- Supracondylar humeral flexion-type fractures are rare. They are usually severe injuries, often resulting in short-term and long-term complications regardless of the original surgical fixation used. [ABSTRACT FROM AUTHOR]

BackgroundIn the 1990s outcomes in Danish lung cancer patients were poor compared with the other Nordic countries. The five-year survival was only about 5%, only 10% of patients were operated on and less than 60% received active surgical or oncologic treatment. This paper describes trends in mortality and survival of lung cancer in Denmark from 2000 to 2012. MethodsThe study population comprised 52 435 patients with a diagnosis of cancer of the trachea and the lung, primarily ascertained from the Danish Lung Cancer Register and grouped into three cohorts by year of diagnosis. The outcome measures covered the first year as well as the first full five-year period after diagnosis and comprised absolute mortality rate (per 100 patient years), absolute survival, and the relative survival. All outcomes were estimated for the overall patient population as well as after stratification by covariates. ResultsOverall, the mortality rates have declined significantly over time from 117 per 100 patient years to 88 for the one-year mortality and from 75 to 65 for the five-year mortality rates, respectively. With the exception of patients with advanced stage, declining mortality was observed for all strata by gender, comorbidity, stage and surgery status and was accompanied by corresponding improvements in both absolute and relative survival. ConclusionsThe mortality has been significantly declining and the prognosis correspondingly improving in lung cancer in Denmark since the turn of the millennium. As of today, survival after lung cancer in Denmark is probably in line with the international standard. Based on our results we recommend introducing mortality indicators based on all-cause mortality within the patient population in international benchmarking studies as comparisons based on cancer-specific mortality relative to the total general population may be misleading when interpreted in the context of outcomes and quality of care.

Background:In addition to fatigue, pain is the most frequent persistent symptom in cancer survivors. Clear guidelines for both the diagnosis and treatment of pain in cancer survivors are lacking. Classification of pain is important as it may facilitate more specific targeting of treatment. In this paper we present an overview of nociceptive, neuropathic and central sensitization pain following cancer treatment, as well as the rationale, criteria and process for stratifying pain classification. Material and methods:Recently, a clinical method for classifying any pain as either predominant central sensitization pain, neuropathic or nociceptive pain was developed, based on a large body of research evidence and international expert opinion. We, a team of 15 authors from 13 different centers, four countries and two continents have applied this classification algorithm to the cancer survivor population. Results:The classification of pain following cancer treatment entails two steps: (1) examining the presence of neuropathic pain; and (2) using an algorithm for differentiating predominant nociceptive and central sensitization pain. Step 1 builds on the established criteria for neuropathic pain diagnosis, while Step 2 applies a recently developed clinical method for classifying any pain as either predominant central sensitization pain, neuropathic or nociceptive pain to the cancer survivor population. Conclusion:The classification criteria allow identifying central sensitization pain following cancer treatment. The recognition of central sensitization pain in practice is an important development in the integration of pain neuroscience into the clinic, and one that is relevant for people undergoing and following cancer treatment.
