Cemented Exeter total hip arthroplasty with a 32 mm head on highly crosslinked polyethylene: Does age influence functional outcome, satisfaction, activity, stem migration, and periprosthetic bone mineral density?

OBJECTIVES: Our primary aim was to describe migration of the Exeter stem with a 32 mm head on highly crosslinked polyethylene and whether this is influenced by age. Our secondary aims were to assess functional outcome, satisfaction, activity, and bone mineral density (BMD) according to age. PATIENTS AND METHODS: A prospective cohort study was conducted. Patients were recruited into three age groups: less than 65 years (n = 65), 65 to 74 years (n = 68), and 75 years and older (n = 67). There were 200 patients enrolled in the study, of whom 115 were female and 85 were male, with a mean age of 69.9 years (sd 9.5, 42 to 92). They were assessed preoperatively, and at three, 12 and, 24 months postoperatively. Stem migration was assessed using Einzel-Bild-Röntgen-Analyse (EBRA). Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Harris Hip Score (HHS), Hip Disability and Osteoarthritis Outcome Score (HOOS), EuroQol-5 domains questionnaire (EQ-5D), short form-36 questionnaire (SF-36,) and patient satisfaction were used to assess outcome. The Lower Extremity Activity Scale (LEAS), Timed Up and Go (TUG) test, and activPAL monitor (energy expelled, time lying/standing/walking and step count) were used to assess activity. The BMD was assessed in Gruen and Charnley zones. RESULTS: Mean varus/valgus tilt was -0.77° and axial subsidence was -1.20 mm. No significant difference was observed between age groups (p ⩾ 0.07). There was no difference according to age group for postoperative WOMAC (p ⩾ 0.11), HHS (p ⩾ 0.06), HOOS (p ⩾ 0.46), EQ-5D (p ⩾ 0.38), patient satisfaction (p ⩾ 0.05), or activPAL (p ⩾ 0.06). Patients 75 years and older had a worse SF-36 physical function (p = 0.01) and physical role (p = 0.03), LEAS score (p < 0.001), a shorter TUG (p = 0.01), and a lower BMD in Charnley zone 1 (p = 0.02). CONCLUSION: Exeter stem migration is within normal limits and is not influenced by age group. Functional outcome, patient satisfaction, activity level, and periprosthetic BMD are similar across all age groups.Cite this article: N. D. Clement, M. Bardgett, K. Merrie, S. Furtado, R. Bowman, D.

COPD exacerbations: management and hospital discharge.

Chronic Obstructive Pulmonary Disease (COPD) is a serious pulmonary condition. Many patients experience exacerbations and some require Emergency Room visits and hospitalization. In Portugal, hospitalizations due to COPD between 2009 and 2016 decreased by 8%, but they still represented 8049 hospitalized patients in 2016. Appropriate management of COPD exacerbations presents a clinical challenge and, in order to guide therapy, it is important to identify the underlying cause; however, this is not possible in about a third of severe COPD exacerbations. There are several diagnostic tools that can be used to assess an exacerbation and its severity, which will in turn guide treatment, and prognostic scores should be used to predict the risk of future exacerbations. After an exacerbation is appropriately managed, a suitable discharge plan should be prepared. This should generally include reclassification of the patient according to GOLD criteria, optimization of pharmacological therapy, management of comorbidities, patient (or caregiver) education on the correct use of medications, referral to a Pulmonology Outpatient Clinic, if they are not already attending one, and a smoking cessation and respiratory rehabilitation program. In this paper, we will focus on the pharmacological strategies for the management of COPD exacerbations, risk stratification and a hospital discharge plan proposal.

Idiopathic pulmonary fibrosis in the era of antifibrotic therapy: Searching for new opportunities grounded in evidence.

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease that up to now has been associated with a poor prognosis. However, the results of the INPULSIS and ASCEND trials and the approval of nintedanib and pirfenidone have marked the beginning of a new era for IPF patients. Questions remain, however. Should these drugs be used earlier? What effect will they have on more severe disease? Will their effects last beyond the trial period? This manuscript is the outcome of a multidisciplinary meeting between pulmonology, radiology, and pathology clinicians on the use of antifibrotic agents in IPF. In our opinion, the existing data show that pirfenidone and nintedanib slow functional decline in early stages of disease. These drugs also appear to result in therapeutic benefits when administered to patients with advanced disease at diagnosis and maintain effective over time. The data also suggest that continuing antifibrotic therapy after disease progression may confer benefits, but more evidence is needed. Early diagnosis and treatment are crucial for reducing functional decline, slowing disease progression, and improving quality of life.

Issues of Survivorship and Rehabilitation in Soft Tissue Sarcoma.

As the number of survivors of extremity soft tissue sarcoma increases, so does the need to understand the experience of survivors and develop measures, systems and services that support rehabilitation into normal life roles. Survivorship includes considerations of the physical, psychological and social domains, of which the physical sequelae of treatment are the best characterised in the literature. The survivorship experience may include disability, pain, lymphoedema, psychological problems, as well as difficulty with employment, relationships and lower quality of life. Rehabilitation strategies for extremity sarcoma patients must be personalised, holistic and begin early in the pathway, ideally before the first treatment intervention. The International Classification of Functioning, Disability and Health model is a useful framework for combining assessments, including objective outcome measures, which can be combined into a rehabilitation prescription. Research is needed to develop an evidence base for rehabilitation interventions to support patients with extremity soft tissue sarcoma.

Objective clinical measurement of physical functioning after treatment for lower extremity sarcoma - A systematic review.

BACKGROUND: Physical impairments and activity restrictions cause significant morbidity after surgery for sarcoma. Yet objective assessment of key components of balance, gait and physical activity (PA), using valid and reliable outcome measures, is lacking in routine clinical practice. PURPOSE OF REVIEW: We therefore performed a systematic review to identify studies quantifying balance, gait and PA in clinically useful ways, after treatment for lower extremity sarcoma. PATIENTS AND METHODS: Relevant articles quantifying balance, gait and PA in patients who underwent surgery for lower extremity bone or soft tissue sarcoma were identified from Medline, Embase, Scopus, and Web of Science up to February 2016. Results were compiled by principal research findings, objective measures used, their ability to detect differences between important clinical groups, change over time and reliability. RESULTS: Eighteen articles were included. Surgery had a significant impact on outcomes (p < 0.05). A wide range of measures and concerns about accuracy of measurement were noted, as gait and PA measures did not discriminate between distinct clinical groups such as limb sparing surgery and amputation, and did not detect changes over time. Few studies investigated reliability (n = 1) and sensitivity to change (n = 4). CONCLUSION: There is a deficit of studies quantifying balance, gait and PA in patients with lower extremity sarcoma. Studies did not use consistent, valid and reliable instruments. There is an urgent need to develop novel objective measures of physical functioning in this patient group to encourage evidence-based clinical care.

Physical functioning, pain and quality of life after amputation for musculoskeletal tumours: a national survey.

Patients who have limb amputation for musculoskeletal tumours are a rare group of cancer survivors. This was a prospective cross-sectional survey of patients from five specialist centres for sarcoma surgery in England. Physical function, pain and quality of life (QOL) outcomes were collected after lower extremity amputation for bone or soft-tissue tumours to evaluate the survivorship experience and inform service provision. Of 250 patients, 105 (42%) responded between September 2012 and June 2013. From these, completed questionnaires were received from 100 patients with a mean age of 53.6 years (19 to 91). In total 60 (62%) were male and 37 (38%) were female (three not specified). The diagnosis was primary bone sarcoma in 63 and soft-tissue tumour in 37. A total of 20 tumours were located in the hip or pelvis, 31 above the knee, 32 between the knee and ankle and 17 in the ankle or foot. In total 22 had hemipelvectomy, nine hip disarticulation, 35 transfemoral amputation, one knee disarticulation, 30 transtibial amputation, two toe amputations and one rotationplasty. The Toronto Extremity Salvage Score (TESS) differed by amputation level, with poorer scores at higher levels (p < 0.001). Many reported significant pain. In addition, TESS was negatively associated with increasing age, and pain interference scores. QOL for Cancer Survivors was significantly correlated with TESS (p < 0.001). This relationship appeared driven by pain interference scores. This unprecedented national survey confirms amputation level is linked to physical function, but not QOL or pain measures. Pain and physical function significantly impact on QOL. These results are helpful in managing the expectations of patients about treatment and addressing their complex needs.

What do we know about survivorship after treatment for extremity sarcoma? A systematic review.

OBJECTIVE: The varied presentations and treatments of extremity bone and soft tissue sarcoma mean that the issues faced by survivors are diverse and complex. The aim of this systematic review was to investigate what is known about this topic with a view to identifying areas for further research or service development. METHODS: This was a review of the English language literature identified from Medline and Ovid and hand searches published between January 2000 and September 2012. Results were compiled according to physical, psychological and social domains of survivorship. RESULTS: Of 182 studies identified, 22 met the inclusion criteria. There is a wide range of outcome measures used and a need for more objective measures. Unsurprisingly, survivors of extremity sarcoma typically demonstrate lower levels of physical functioning than healthy controls. In addition, survivors demonstrate a substantial psychological morbidity. CONCLUSIONS: Services for survivors of extremity sarcoma should include rehabilitation and psychological support, sexual health services, expert pain management, and support to return to work.

Referrals, Wait Times and Diagnoses at an Urgent Neurology Clinic over 10 Years.

BACKGROUND: An urgent neurology assessment clinic was created at our institution to improve access to prompt neurological assessment, and has been in operation for over a decade. We assessed its timeliness and impact. METHODS: The clinic database was examined retrospectively for trends in the volume and waiting time to assessments, neurologic diagnoses, and whether neurologic assessment changed patients' diagnoses. Before and after implementation, the frequency of emergency department neurology assessments and hospital admissions for neurological investigation were compared. RESULTS: In the first decade, 25145 referrals were received; 12460 patients were accepted and assessed within an average of 3.8 working days. The most common problems seen included headache and seizure (20.2% each). Overall, 44.6% of assessments resulted in a change to the referring diagnosis; this proportion varied by the type of problem seen (from 10.5% for seizures to 92.5% for psychiatric disturbances). From the pre- to post-opening periods, there were fewer emergency room neurological assessments (35.7% reduction) and fewer hospital admissions for neurological investigation (4.4/week to 2.2/week, 50% reduction). CONCLUSIONS: The urgent neurology clinic model at our institution has provided excellent service, including wait times of a few days, to a catchment of over two million Canadians for over a decade; clinic assessments have affected diagnoses and patient care.

Can bioadhesive nanoparticles allow for more effective particle uptake from the small intestine?

There has been increasing interest in developing bioadhesive nanoparticles due to their great potential as carriers for therapeutics in oral drug delivery systems. Despite decades of research, such a system still has not been successfully implemented. This paper demonstrates the enormous potential of such engineered systems: the incorporation of a bioadhesive coating, poly(butadiene-maleic anhydride-co-L-DOPA) (PBMAD), to non-bioadhesive nanospheres resulted in an enhancement of particle uptake in the small intestine from 5.8±1.9% to 66.9±12.9%. Direct correlation was obtained between bulk tensile strength, in vitro binding to everted intestinal sacs and quantitative in vivo uptake; this data suggests that bulk properties of polymers can be used to predict bioadhesive properties of nano- and microparticles. The differential distribution of the nanospheres to various tissues following uptake suggests surface chemistry plays a significant role in their localization within the body. The results of these studies provide strong support for the use of bioadhesive polymers to enhance nano- and micro-particle uptake from the small intestine for oral drug delivery.

Multiple nodules on the face and trunk in metastatic adenocarcinoma of unknown primary origin.

Metastatic cancer of unknown primary (CUP) may unexpectedly manifest on the skin and subcutaneous tissue, prompting the patient to first visit a dermatologist. We describe an interesting case of cutaneous metastases from poorly differentiated adenocarcinoma of an unknown primary site in a 57-year-old man. The CUP had an unusually long period of indolence between presentation as a solitary axillary lymph node metastasis and rapid cutaneous dissemination. The possible causes of such a presentation are reviewed, and the management is briefly discussed. Diagnosis of unusual cutaneous manifestations of occult systemic malignancies could pose a diagnostic challenge to dermatologists.

Angiolipoma in sellar, suprasellar and parasellar region: report on two new cases and review of literature.

Angiolipomas of CNS are very rare; more than 90% involve the spinal canal. There are only a few case reports documenting the tumor in the sellar/suprasellar region. We report 2 cases of angiolipoma involving sellar/suprasellar and right parasellar region in two female patients. On histopathology the lesion was composed of vascular component which was of cavernous type in one patient and of capillary caliber in the other with admixture of mature adipocytes. The MRI findings were distinctive as the lesion was predominantly iso-to-hypointense on T1W sequence, hyperintense on T2WI and FLAIR sequence. In addition, a few small hyperintense areas were noted on plain T1W images which may represent intralesional fat. One of the cases also showed lipid lactate peak on MR spectroscopy. To the best of our knowledge only 8 other cases of sellar, parasellar angiolipomas have been reported in indexed literature. MRI with fat suppression sequences should be routinely performed in lesions in such locations with hyperintense areas on T1WI as the incidence of intraoperative blood loss is very high. A preoperative suspicion of the diagnosis might help in reducing the patient morbidity.
