Background: CT guided lung biopsy is a commonly performed procedure to obtain tissue for a histological diagnosis in cases of suspected lung cancer. Methods: This is a prospective cohort study to obtain information directly from patients about their experiences of the biopsy procedure, thus obtaining a more accurate picture of complications compared with previously performed retrospective reviews. Patients participated in a post-procedure telephone interview and information was gathered about any procedural complications and personal experiences. We also compared the patient reported complications with those obtained from a retrospective review of hospital databases, analogous to previously performed retrospective studies. Results: In our patient group, reported procedural complication rates were 10% pneumothorax rate (4% requiring a chest drain) and 10% haemoptysis. Post-procedural pain and shortness of breath showed positive correlation, with one patient experiencing prolonged pain. No statistical difference was found between the patient reported complication rates and those obtained from retrospective review of the hospital database. Conclusions: Our study demonstrates CT guided lung biopsy is a safe procedure and is generally well tolerated. Some patients may experience significant and lasting pain and therefore should be counselled about this pre-procedure. © 2014 Winn et al.

The issues surrounding raised levels of metal ions in the blood following large head metalonmetal total hip replacement (THR), such as cobalt and chromium, have been well documented. Despite the national popularity of uncemented metal-on-polyethylene (MoP) THR using a large-diameter femoral head, few papers have reported the levels of metal ions in the blood following this combination. Following an isolated failure of a 44 mm Trident-Accolade uncemented THR associated with severe wear between the femoral head and the trunnion in the presence of markedly elevated levels of cobalt ions in the blood, we investigated the relationship between modular femoral head diameter and the levels of cobalt and chromium ions in the blood following this THR. A total of 69 patients received an uncemented Trident-Accolade MoP THR in 2009. Of these, 43 patients (23 men and 20 women, mean age 67.0 years) were recruited and had levels of cobalt and chromium ions in the blood measured between May and June 2012. The patients were then divided into three groups according to the diameter of the femoral head used: 12 patients in the 28 mm group (controls), 18 patients in the 36 mm group and 13 patients in the 40 mm group. A total of four patients had identical bilateral prostheses in situ at phlebotomy: one each in the 28 mm and 36 mm groups and two in the 40 mm group. There was a significant increase in the mean levels of cobalt ions in the blood in those with a 36 mm diameter femoral head compared with those with a 28 mm diameter head (p = 0.013). The levels of cobalt ions in the blood were raised in those with a 40 mm diameter head but there was no statistically significant difference between this group and the control group (p = 0.152). The levels of chromium ions in the blood were normal in all patients. The clinical significance of this finding is unclear, but we have stopped using femoral heads with a diameter of ≤ 36 mm, and await further larger studies to clarify whether, for instance, this issue particularly affects this combination of components. © 2014 The British Editorial Society of Bone & Joint Surgery.

To review whether osteoporosis in the absence of vertebral fracture (VFX) affects health-related quality of life (HRQoL), a systematic search of the main literature databases for HRQoL in patients with osteoporosis without VFX was undertaken. This was undertaken. This identified 1,327 articles as potentially relevant to the review. After screening of abstracts and reviewing 168 articles in detail, 27 were considered relevant. HRQoL data were extracted and collated into tables and, where possible, were converted into normative scores and further analysed. Data relating to the associations between HRQoL and bone mineral density (BMD) were also collated. Of the 27 articles included, only 5 directly compared osteoporosis without VFX with a control group (BMD T-score>-1.0, without VFX). Extracted raw data from 21 articles demonstrated that patients with osteoporosis without VFX had clinically relevant reductions in role physical, general health, vitality, mental health domains and the mental component summary score, using SF36. Using Qualeffo-41, pain and physical function were worse in these patients. Also, HRQoL was related to upper femur, but not lumbar spine BMD. HRQoL data in patients with osteoporosis without VFX are limited and variable but suggest that HRQoL is adversely affected by osteoporosis in the absence of VFX. The association of lower BMD and worse HRQoL suggests that more attention should be paid to HRQoL in those without VFX. Future studies are needed to investigate HRQoL in patients with osteoporosis in the absence of fracture, controlling for co-morbidities and social and economic status. © International Osteoporosis Foundation and National Osteoporosis Foundation 2012.

Plots are an elegant and effective way to represent data. At their best they encourage the reader and promote comprehension. A graphical representation can give a far more intuitive feel to the pattern of results in the study than a list of numerical data, or the result of a statistical calculation. The temptation to exaggerate differences or relationships between variables by using broken axes, overlaid axes, or inconsistent scaling between plots should be avoided. A plot should be self-explanatory and not complicated. It should make good use of the available space. The axes should be scaled appropriately and labelled with an appropriate dimension. Plots are recognised statistical methods of presenting data and usually require specialised statistical software to create them. The statistical analysis and methods to generate the plots are as important as the methodology of the study itself. The software, including dates and version numbers, as well as statistical tests should be appropriately referenced. Following some of the guidance provided in this article will enhance a manuscript. © 2015 The British Editorial Society of Bone & Joint Surgery.

Objective. To determine the effect of 6 years of routine management on body composition, physical functioning, and quality of life, and their interrelationships, in men with idiopathic vertebral fracture. Methods. Twenty men with idiopathic vertebral fracture (patients: mean ± SD age 58 ± 6 years) were age and height matched to 28 healthy controls with no known disease. The primary outcome was skeletal muscle mass (appendicular lean mass by dual X-ray absorptiometry) assessed at 2 visits (0 and 6 years). Physical functioning and quality of life domains were assessed by the Senior Fitness Test and Short Form 36 (SF-36) questionnaire at visit 2 only. Data were analyzed by repeated-measures analysis of variance, independent t-tests, and correlation. Results. At visit 1, appendicular lean mass was 9% lower in patients than controls. Although patients better maintained appendicular lean mass between visits (interaction P = 0.016), at visit 2 appendicular lean mass remained 5% lower in patients than controls. Furthermore, patients' appendicular lean mass change was correlated with femoral neck bone density change (r = 0.507, P = 0.023). Physical function tests were 13-27% lower in patients compared with controls (P = 0.056 to 0.003), as were SF-36 quality of life physical domains (13-26% lower; P = 0.028 to <0.001). Conclusion. Despite an association between changes in muscle mass and bone density, routine management of men with idiopathic vertebral fracture does not address muscle loss. Combined with the observation of reduced physical functioning and quality of life, this study identifies novel targets for intervention in men with idiopathic vertebral fracture. © 2012, American College of Rheumatology.

Purpose: There is much interest in the development of a cellular therapy for the repair or regeneration of degenerate intervertebral discs (IVDs) utilising autologous cells, with some trials already underway. Clusters of cells are commonly found in degenerate IVDs and are formed via cell proliferation, possibly as a repair response. We investigated whether these clusters may be more suitable as a source of cells for biological repair than the single cells in the IVD. Methods: Discs were obtained at surgery from 95 patients and used to assess the cell viability, growth kinetics and stem or progenitor cell markers in both the single and clustered cell populations. Results: Sixty-nine percent (±15) of cells in disc tissue were viable. The clustered cell population consistently proliferated more slowly in monolayer than single cells, although this difference was only significant at P0–1 and P3–4. Both populations exhibited progenitor or notochordal cell markers [chondroitin sulphate epitopes (3B3(−), 7D4, 4C3 and 6C3), Notch-1, cytokeratin 8 and 19] via immunohistochemical examination; stem cell markers assessed with flow cytometry (CD73, 90 and 105 positivity) were similar to those seen on bone marrow-derived mesenchymal stem cells. Conclusions: These results confirm those of previous studies indicating that progenitor or stem cells reside in adult human intervertebral discs. However, although the cell clusters have arisen via proliferation, there appear to be no greater incidence of these progenitor cells within clusters compared to single cells. Rather, since they proliferate more slowly in vitro than the single cell population, it may be beneficial to avoid the use of clustered cells when sourcing autologous cells for regenerative therapies. © 2014, Springer-Verlag Berlin Heidelberg.

Purpose To evaluate correlations between objective performances measured by a new online arthroscopic skills acquisition tool (ASAT, in which "shape match" with inverted controls requires lifting shapes and releasing them into their corresponding silhouettes) and a validated virtual reality (VR) shoulder arthroscopy simulator (Insight Arthro VR; GMV, Madrid, Spain). Methods Forty-nine medical students familiarized themselves with 5 ASATs. They were then assessed using a sixth ASAT (shape match with inverted controls) and 4 VR tasks (operating room, visualize, locate and palpate, and pendulum) on the VR simulator. Correlations were assessed between 11 ASAT measures and 15 VR measures using Pearson correlation coefficients. Results Time taken and delta distance (actual distance minus minimum distance traveled) were the most frequent and correlated ASAT measures. Time taken correlated with the VR locate-and-palpate time (r = 0.596, P <.001), visualize time (r = 0.381, P =.007), and pendulum time (r = 0.646, P <.001), whereas delta distance correlated with the locate-and-palpate camera distance (r = 0.667, P <.001), instrument distance (r = 0.664, P <.001), visualize distance (r = 0.4, P =.004), pendulum camera distance (r = 0.538, P <.001), and instrument distance (r = 0.539, P <.001). Conclusions There were significant correlations between performance measures on the ASAT and a validated arthroscopic VR simulator. Clinical Relevance Arthroscopic simulators are available but are limited by their high cost and availability. ASATs may overcome these limitations by using widely available Internet-based software and basic input devices. © 2015 Arthroscopy Association of North America.

Three-dimensional laser scanning has been used for patient measurement for cranial helmets and spinal braces. Ankle-foot orthoses are commonly prescribed for children with orthopaedic conditions. This trial sought to compare ankle-foot orthoses produced by laser scanning or traditional plaster casting.Assessment of the effectiveness and efficiency of using laser scanning to produce ankle-foot orthoses.Randomised controlled trial with blinding of orthotists and patients to the construction technique used.A randomised double-blind trial comparing fabrication of ankle-foot orthoses from casts or laser scans.The time spent in the rectification and moulding of scanned ankle-foot orthoses was around 50% less than for cast ankle-foot orthoses. A non-significant increase of 9days was seen in the time to delivery to the patient for laser scanning with computer-aided design and computer-aided manufacturing. There was a higher incidence of problems with the scan-based ankle-foot orthoses at delivery of the device, but no difference in how long the ankle-foot orthoses lasted. Costs associated with laser scanning were not significantly different from traditional methods of ankle-foot orthosis manufacture.Compared with conventional casting techniques, laser scan-based ankle-foot orthosis manufacture did not significantly improve either the quality of the final product or the time to delivery.Ankle-foot orthoses (AFOs) are a common requirement for chronic neurological conditions during childhood. Improved efficiency of provision of AFOs would benefit children and families by reducing the delay in provision of devices and would benefit the health service by making best use of valuable orthotist time.

The purpose of this study was to determine if clinical and radiological surveillance of cartilage tumours with low biological activity is appropriate.A total of 98 patients with an intramedullary cartilage neoplasm in a long bone met our inclusion criteria and were included in the study. These patients had undergone a total of 384 scans. Patients with radiological follow-up of more than three years (46 patients) were divided into two groups: an active group (11 patients) and a latent group (35 patients).Active lesions had a total growth in all three planes that was > 6 mm, whilst latent lesions had < 6 mm of growth. Most latent lesions were heavily calcified: active lesions were calcified less than 50% (p = 0.025).Clinico-radiological surveillance can identify growing cartilage lesions: MRI is the surveillance modality of choice. A CT scan is recommended, in addition, at presentation to assess the amount of calcification within the lesion. A first follow-up MRI is suggested one year from diagnosis. If the total growth in the cartilage lesion is > 6 mm, surgical treatment should be considered. Otherwise, a second surveillance scan can be performed at three years to determine further management.

Much emphasis has been placed recently on the repair of degenerate discs using implanted cells, such as disc cells or bone marrow derived mesenchymal stem cells (MSCs). This study examines the temporal response of bovine and human nucleus pulposus (NP) cells and MSCs cultured in monolayer following exposure to altered levels of glucose (0, 3.15, and 4.5g/L) and foetal bovine serum (0, 10, and 20%) using an automated time-lapse imaging system. NP cells were also exposed to the cell death inducers, hydrogen peroxide and staurosporine, in comparison to serum starvation. We have demonstrated that human NP cells show an initial shock response to reduced nutrition (glucose). However, as time progresses, NP cells supplemented with serum recover with minimal evidence of cell death. Human NP cells show no evidence of proliferation in response to nutrient supplementation, whereas MSCs showed greater response to increased nutrition. When specifically inducing NP cell death with hydrogen peroxide and staurosporine, as expected, the cell number declined. These results support the concept that implanted NP cells or MSCs may be capable of survival in the nutrient-poor environment of the degenerate human disc, which has important clinical implications for the development of IVD cell therapies.
