Metaphyseal Sleeve Failure in Revision Total Knee Arthroplasty.

Introduction A significant percentage of patients require re-revision surgery regardless of the demonstrated durable short- and mid-term clinical results using metaphyseal sleeves in revision total knee arthroplasty (TKA). The aim of this study was to identify the association between sleeve alignment and contact zones, with loosening in patients with revision TKA. Materials & Methods Of a series of 103 patients who underwent revision TKA, at a mean follow-up of eight years, six patients were re-revised for tibial loosening.

Correlation of quality of life with instrumented analysis of a total knee arthroplasty series at the long-term follow-up.

Purpose: The relationship between instrumented knee measurements and patient-reported outcome measures is a newer field that continues to evolve. The aim of this study was to evaluate long-term quality of life (QoL) post-total knee arthroplasty (TKA) surgery correlating validated self-reported questionnaires, clinical examination and instrumented analysis, using baropodometry and accelerometry.

Methods: Thirty-six patients who underwent primary unilateral TKA between 1999 and 2006 were evaluated at 11.

The Oswestry-Bristol Classification.

Aims: Trochlear dysplasia is a significant risk factor for patellofemoral instability. The Dejour classification is currently considered the standard for classifying trochlear dysplasia, but numerous studies have reported poor reliability on both plain radiography and MRI. The severity of trochlear dysplasia is important to establish in order to guide surgical management.

The main aim of this case report is to thoroughly describe the steps of diagnosis and treatment in the rare incidence of patellar tendon gouty tophus. The case of a 53-year-old man manual worker who was treated with open excision of the lesion, following failure of extended medical treatment with rheumatological input, is presented. Surgical treatment led to full restoration of the patient's knee function.

Isolated medial patellofemoral ligament reconstruction significantly improved quality of life in patients with recurrent patella dislocation.

Purpose: The purpose of this study was to measure the improvement in quality of life (QoL) following isolated anatomical double-bundle medial patellofemoral ligament reconstruction.

Methods: This is a single-centre, prospective study of 56 consecutive patients (57 knees) who underwent isolated MPFL reconstruction between 2014 and 2017. Functional outcome and QoL were assessed with the Kujala score and the EQ-5D-3L questionnaire, respectively.

Decision Making for the Surgical Treatment of Vertebral Metastases Among Patients with Short Predicted Survival.

Background: A wide spectrum of treatment choices is proposed for poor-prognosis patients with vertebral metastases. The continuous increase of this population and the propagation of less invasive techniques necessitate further study concerning which patients could benefit from palliative surgery.

Methods: All patients with a Tokuhashi score ≤8 who had undergone palliative surgical treatment for vertebral metastasis within 4 years were retrospectively reviewed.

Which functional outcome parameters correlate better with elderly patients' satisfaction after non-fusion lumbar spine surgery?

Background: Elderly patients are increasingly operated for spinal degenerative diseases. The treatment objective is quality of life, which, in this population, is difficult to assess. Hence, patient satisfaction, although less objective, is of high importance.

Stenotic intercondylar notch type is correlated with anterior cruciate ligament injury in female patients using magnetic resonance imaging.

Purpose And Hypothesis: The principal purpose of this paper was to identify whether femoral notch morphology was different in females without anterior cruciate ligament (ACL) injury from those with ACL injury. Magnetic resonance imaging (MRI) was used to assess the femoral notch type, notch width index and 'α angle' in female patients and measure these differences.

Methods: This is a retrospective case control study of 119 female patients, 58 with ACL injury and 61 patients without ACL injury who underwent knee MRI between March 2014 and April 2016.

Good long-term results following cementless TKA with a titanium plasma coating.

Purpose: While cemented total knee arthroplasty (TKA) is currently the gold standard for primary osteoarthritis, cementless component fixation has achieved increasingly comparable outcomes due to improvements in both implant designs and surgical technique. Long-term outcomes and survivorship with the TC-Plus cementless, titanium plasma-coated TKA system without patella resurfacing were evaluated.

Methods: A homogenous population of 171 consecutive patients who received 206 primary TC-Plus TKAs without patella resurfacing over a 19-year period was retrospectively reviewed.

Perioperative microdialysis in meningioma surgery: correlation of cerebral metabolites with clinical outcome.

Background: Brain tumour resection requires surgical manoeuvres that may cause an ischaemic injury to peritumoral tissue. The aim of the present study was to examine whether putative alterations in peritumoral tissue biochemistry, monitored by microdialysis, correlate with clinical outcome in patients undergoing craniotomy for meningioma resection.

Methods: In 34 patients undergoing meningioma resection (35 % male; mean age ± SD: 54.

Comparison of minimally invasive approach versus conventional anterolateral approach for total hip arthroplasty: a randomized controlled trial.

Background: It is a general belief among hip surgeons that minimally invasive surgical (MIS) approach for implantation of a total hip arthroplasty (THA) allows an improved and faster postoperative rehabilitation because of reduced muscle and soft-tissue damage, less postoperative pain and blood loss, and shorter hospital stay compared with conventional approaches. In the published relative literature though, there are controversial reports and debates on this matter. To our knowledge, there is no study on the medium-term functional results comparing MIS and traditional approaches for total hip replacement.

Low aseptic loosening and revision rate in Zweymüller-Plus total hip arthroplasty with ceramic-on-ceramic bearings.

Unlabelled: A recent comparative study reported lower revision rate and higher survival in ceramic-on-ceramic (CoC) than in metal-on-metal (MoM) coupling in Zweymüller-Plus THA. We retrospectively studied 87 consecutive patients (94 hips), who primarily received Zweymüller-Plus THA (SL-Plus stem, ceramic 28-mm ball head, Bicon cup) with third-generation CoC bearing surfaces for osteoarthritis. Survival, revision and osteolysis rate were studied and compared to those observed in historical series from this institution with the same THA and MoM articulation.

Effect of wastewater chlorination on endocrine disruptor removal.

Endocrine disrupting chemicals (EDCs) are compounds of mainly anthropogenic origin that interfere with the endocrine system of animals and humans thus causing a series of disorders. Wastewater treatment plants are one of the major routes for transporting such chemicals to the water courses. In the context of this study, several chlorination batch tests were performed in order to assess the effectiveness of chlorination to remove bisphenol A (BPA), triclosan (TCS), nonylphenol (NP) and its ethoxylates (NP1EO and NP2EO) from secondary effluent.

Global changes in the mammary epigenome are induced by hormonal cues and coordinated by Ezh2.

The mammary epithelium is a dynamic, highly hormone-responsive tissue. To explore chromatin modifications underlying its lineage specification and hormone responsiveness, we determined genome-wide histone methylation profiles of mammary epithelial subpopulations in different states. The marked differences in H3K27 trimethylation between subpopulations in the adult gland suggest that epithelial cell-fate decisions are orchestrated by polycomb-complex-mediated repression.

Complications of endoscopic third ventriculostomy.

Background: The treatment of choice for several types of obstructive hydrocephalus is endoscopic third ventriculostomy (ETV). However, in certain cases ETV is not clearly superior to shunt placement, and a question of choice arises. Apart from the possibility of success in each case, knowledge of complication rates is of major importance as well.

Complications of endoscopic third ventriculostomy: a systematic review.

Introduction: Endoscopic third ventriculostomy (ETV) is an established treatment for hydrocephalus. Most studies focus on success rates, and complications are insufficiently charted. The aim of this study was to perform a systematic review of ETV complications.

Neuro-inflammatory Sequelae of Minimal Trauma in the Non-traumatized Human Brain: A Microdialysis Study.

Cytokine measurement directly from the brain parenchyma by means of microdialysis has documented the activation of certain procedures , after brain trauma in humans. However, the intercalation of the micro-catheter insertion with the phenomena triggered by the head trauma renders the assessment of the findings problematic. The present study attempts to elucidate the pure effect of minimal trauma, represented by the insertion of the micro-catheter, on the non-traumatized human brain.

Lineage specific methylation of the Elf5 promoter in mammary epithelial cells.

Recent characterization of mammary stem and progenitor cells has improved our understanding of the transcriptional network that coordinates mammary development; however, little is known about the mechanisms that enforce lineage commitment and prevent transdifferentiation in the mammary gland. The E-twenty six transcription factor Elf5 forces the differentiation of mammary luminal progenitor cells to establish the milk producing alveolar lineage. Methylation of the Elf5 promoter has been proposed to act as a lineage gatekeeper during embryonic development.

SEMPATH Ontology: modeling multidisciplinary treatment schemes utilizing semantics.

A dramatic increase of demand for provided treatment quality has occurred during last decades. The main challenge to be confronted, so as to increase treatment quality, is the personalization of treatment, since each patient constitutes a unique case. Healthcare provision encloses a complex environment since healthcare provision organizations are highly multidisciplinary.
