Revision total hip arthroplasty in the setting of a large proximal femoral deficiency or a peri-prosthetic fracture remains a challenging problem. We describe the development, surgical technique and the use of cementless revision stems with distal inter-locking screws to provide immediate stability of the femoral implant. Results were assessed in a large multicentre French study conducted with the french hip and knee surgery society (SFHG). We retrospectively reviewed 725 revisions using interlocking stems from 14 French orthopaedic departments. Seven different stems were used in this series. In-patient records were retrieved, and in addition to demographic data the indication for revision, the preoperative and postoperative PMA and Harris hip scores were documented. The bone deficiency was classified on the basis of the French National Orthopaedic Meeting (SOFCOT) classification. Intraoperative complications and problems if any were retrieved from operative notes. Clinical status and radiographs at the final follow-up were evaluated, paying special attention to the metaphyseal filling index. Average follow-up was 4.5 years. As for the clinical results, the mean Harris hip score at last follow-up was 81. Therefore, it increased by an average of 31 points. Bone reconstruction was assessed on the cortico-medullary index in the metaphyseal area and at mid-shaft increasing from 36 to 45 and 54 to 63, respectively. Radiologically, 637 implants were stable, and 40 demonstrated subsidence. Forty-eight implants have been revised. We found a significant relation between the metaphyseal filling index, the stability of the stem and the quality of bone reconstruction. Results were analysed with respect to three groups of stems: group 1 was a straight, partially HA-coated implant; group 2 was a curved, fully HA-coated implant; and group 3 was a curved, partially-coated implant. Group 1 showed a significantly higher rate of failure when compared with the others types of implants. Group 2 had better functional results than group 3, which in turn reported better results than group 1. With regard to implant fixation, group 2 had significantly better results. Both groups 2 and 3 induced less thigh pain than group 1. The distal interlocking stem has shown promising results for femoral revisions. The advantages are initial axial and rotational stability and consistent bony in-growth owing to hydroxyapatite coating. Distal locked stems are mainly indicated to treat complex femoral revision with severe bone loss and peri-prosthetic fractures. © Springer-Verlag 2010.

Monoclonal immunoglobulin deposition disease (MIDD) is a rare complication of plasma cell disorders, defined by linear Congo red-negative deposits of monoclonal light chain, heavy chain, or both along basement membranes. While renal involvement is prominent, treatment strategies, such as the impact of novel anti-myeloma agents, remain poorly defined. Here we retrospectively studied 49 patients with MIDD who received a median of 4.5 cycles of intravenous bortezomib plus dexamethasone. Of these, 25 received no additional treatment, 18 also received cyclophosphamide, while 6 also received thalidomide or lenalidomide. The hematological diagnoses identified 38 patients with monoclonal gammopathy of renal significance, 10 with symptomatic multiple myeloma, and 1 with Waldenstrom macroglobulinemia. The overall hematologic response rate, based on the difference between involved and uninvolved serum-free light chains (dFLCs), was 91%. After median follow-up of 54 months, 5 patients died and 10 had reached end-stage renal disease. Renal response was achieved in 26 patients, with a 35% increase in median eGFR and an 86% decrease in median 24-h proteinuria. Predictive factors were pre-treatment eGFR over 30 ml/min per 1.73 m 2 and post-treatment dFLC under 40 mg/l; the latter was the sole predictive factor of renal response by multivariable analysis. Thus, bortezomib-based therapy is a promising treatment strategy in MIDD, mainly when used early in the disease course. dFLC response is a favorable prognostic factor for renal survival. © 2015 International Society of Nephrology.

Background Ciclosporin and infliximab are potential rescue treatments to avoid colectomy in patients with acute severe ulcerative colitis refractory to intravenous corticosteroids. We compared the efficacy and safety of these drugs for this indication. Methods In this parallel, open-label, randomised controlled trial, patients were aged at least 18 years, had an acute severe flare of ulcerative colitis defined by a Lichtiger score greater than 10 points, and had been given an unsuccessful course of high-dose intravenous steroids. None of the patients had previously received ciclosporin or infliximab. Between June 1, 2007, and Aug 31, 2010, patients at 27 European centres were randomly assigned (via computerderived permutation tables; 1:1) to receive either intravenous ciclosporin (2 mg/kg per day for 1 week, followed by oral drug until day 98) or infliximab (5 mg/kg on days 0, 14, and 42). In both groups, azathioprine was started at day 7 in patients with a clinical response. Neither patients nor investigators were masked to study treatment. The primary efficacy outcome was treatment failure defined by absence of a clinical response at day 7, a relapse between day 7 and day 98, absence of steroid-free remission at day 98, a severe adverse event leading to treatment interruption, colectomy, or death. Analysis was by intention to treat. This trial is registered with EudraCT (2006-005299-42) and ClinicalTrials.gov (NCT00542152). Findings 115 patients were randomly assigned; 58 patients were allocated to receive ciclosporin and 57 to receive infliximab. Treatment failure occurred in 35 (60%) patients given ciclosporin and 31 (54%) given infliximab (absolute risk difference 6%; 95% CI -7 to 19; p=0·52). Nine (16%) patients in the ciclosporin group and 14 (25%) in the infliximab group had severe adverse events. Interpretation Ciclosporin was not more effective than infliximab in patients with acute severe ulcerative colitis refractory to intravenous steroids. In clinical practice, treatment choice should be guided by physician and centre experience.

background: The aim of this systematic review was to evaluate the fertility outcome after borderline ovarian tumor (BOT) management and the results of conservative management, risk of recurrence and alternative options.methods: The search strategy was based on relevant terms concerning BOT using Medline and the Central Cochrane Library. Both early and advanced stages of serous and mucinous BOT were included, but not rare entities such as endometrioid, Brenner or clear-cell BOT because of their low incidence. We considered all articles-case reports, original studies, meta-analyses and reviews-in English and French.results: Overall, 230 articles were screened of which 120 were retained for review. Most pregnancies were spontaneous but some data were obtained from studies analyzing the contribution of assisted reproductive technology (ART). However, not all studies differentiated spontaneous pregnancy from those obtained after fertility treatment including ovulation induction, intrauterine insemination and IVF. Conservative management of early stage BOT resulted in a pooled estimate for spontaneous pregnancy rate of 54% with a low risk of lethal recurrence (pooled estimate: 0.5%). In patients with advanced stage BOT, the spontaneous pregnancy rates was lower (34% in the single series reporting pregnancy rate in this context) and the risk of lethal recurrence increased (pooled estimate: 2%).conclusions: This systematic review underlines that fertility subsequent to treatment of BOT depends mainly on histology and initial staging to distinguish early from advanced stages. In patients with advanced stage BOT, several alternative options to conservative management are available to allow patients to conceive without compromising their prognosis. © The Author 2012.

Objective. Fatigue frequently occurs in patients with early arthritis (EA). Determinants of its severity are unknown. We aimed to identify the factors associated with fatigue in EA and changes in fatigue after 1 year of followup. Methods. The Evaluation et Suivi de Polyarthrites Indifférenciées Récentes (Assessment and Followup of Early Undifferentiated Arthritis) cohort study is a multicenter, prospective, national cohort of patients with EA. At baseline and every 6 months up to 1 year, we recorded sociodemographic, clinical, and treatment characteristics, Arthritis Impact Measurement Scales 2 Short Form (AIMS2-SF) and Short Form 36 (SF-36) scores for health-related quality of life (HRQOL), and fatigue severity by a visual analog scale (f-VAS) and the SF-36 vitality score (fatigue-SF36). Results. We included 813 patients (77% women, mean ± SD age 48 ± 13 years). At baseline, fatigue as assessed by the f-VAS or fatigue-SF36 was independently associated with young age, female sex, low education level, smoking, increased Disease Activity Score in 28 joints (DAS28), waking up at night, Sjögren's syndrome, and worse AIMS2-SF physical, affect, and symptom scores. At 1-year followup, a favorable change in fatigue scores was associated with increased baseline AIMS2-SF physical and affect scores (better quality of life), high baseline fatigue scores, and improved 1-year AIMS2-SF affect scores. Age, sex, and change in AIMS2-SF physical score, DAS28, and hemoglobin or C-reactive protein level were inconsistently associated with change in fatigue scores. The AIMS2-SF affect score explained most of the variance in baseline fatigue score and was an important factor in 1-year change in fatigue score. Conclusion. Fatigue in EA is multifactorial. Its level and its course are strongly associated with HRQOL, notably the affect dimension. These results should help professionals inform patients about fatigue, explore its causes, and develop tailored interventions. © 2012, American College of Rheumatology.

Summary: Inflammatory bowel diseases are characterized by a deregulated immune response targeting the gut bacterial flora. Mucosal-associated invariant T (MAIT) cells are major histocompatibility complex (MHC) class Ib-restricted innate-like lymphocytes with anti-bacterial functions. They display an effector/memory phenotype and are found in large numbers in the blood, mucosae and liver. They have also been implicated in inflammatory diseases such as multiple sclerosis. Therefore, we aimed to analyse the possible involvement of MAIT cells in Crohn's disease (CD) and ulcerative colitis (UC). To this end, a phenotypical and functional analysis of MAIT cells isolated from the blood of healthy subjects, CD and UC patients was undertaken. MAIT cells were also quantified in ileal biopsies of CD patients. The frequency of blood MAIT cells was specifically reduced in IBD patients compared with healthy donors, whereas it was dramatically greater in the inflamed versus healthy tissue. MAIT cells were activated as they expressed significantly more the Ki67 antigen, and this was accompanied by phenotypical changes such as increased expression of natural killer (NK)G2D and B and T lymphocyte attenuator (BTLA). Finally, in-vitro-activated MAIT cells from CD and UC patients secreted significantly more interleukin (IL)-17, together with a decreased interferon (IFN)-γ in CD but an increased IL-22 in UC. These data show that MAIT cells are activated in IBD, which results in an increased recruitment towards the inflamed tissues, an altered phenotype and a switch in the pattern of cytokine secretion. This is the first demonstration that MAIT cells are immune players in IBD, whose precise functions in this context need to be addressed. © 2014 British Society for Immunology.

Objective An annual assessment of cardiovascular (CV) risk factors in rheumatoid arthritis (RA) is recommended, but its practical modalities have not been determined. The objective was to assess the feasibility and usefulness of a standardized CV risk assessment in RA, performed by rheumatologists during outpatient clinics. Methods We used a cross-sectional design within a network of rheumatologists. Each rheumatologist included 5 consecutive unselected patients with definite RA. Data collection included standardized assessment of CV risk factors: blood pressure, interpretation of glycemia and of lipid levels, and calculation of the Framingham CV risk score. Outcome criteria included feasibility (missing data and time taken to assess the patients) and usefulness (the CV risk assessment was considered useful if at least 1 modifiable and previously unknown CV risk factor was evidenced). Results Twenty-two rheumatologists (77% in office-based practice) assessed 110 RA patients. The mean ± SD age was 57 ± 10 years, and the mean ± SD RA duration was 11 ± 9 years; 50 patients (45%) were treated with biologic agents, and 76% were women. Regarding feasibility, missing data were most frequent for glycemia (27% of patients) and cholesterolemia (14% of patients). The mean ± SD duration of the CV risk assessment was 15 ± 5 minutes. The CV risk assessment was considered useful in 33 patients (30%), evidencing dyslipidemia (15% of patients) or high blood pressure (9% of patients) as the most frequently previously unknown CV risk factor. Conclusion The assessment of CV risk factors is feasible, but labor intensive, during an outpatient rheumatology clinic. This assessment identified modifiable CV risk factors in 30% of the patients. These results suggest that RA patients are not sufficiently assessed and treated for CV risk factors. Copyright © 2013 by the American College of Rheumatology.

The aim of the study was to evaluate the role of hypertension in patients hospitalized for serious spontaneous epistaxis. This 6-year retrospective study was based on 219 patients hospitalized in a University Hospital ENT and Head and Neck surgery department for serious spontaneous epistaxis. The following parameters were recorded: length of hospital stay, history of hypertension, blood pressure (BP) recordings (on admission, during hospitalization and on discharge), epistaxis severity criteria, including medical and/or surgical management of epistaxis (blood transfusion depending on blood count, embolization, surgery), medications affecting clotting. Epistaxis was classified into two groups: serious and severe. No significant differences were observed between the two groups in terms of age, sex ratio, history of epistaxis and BP characteristics including history of hypertension, mean BP on admission, mean arterial pressure on discharge and number of patients in whom BP was difficult to control. Patients with more severe epistaxis had a similar exposure to anticoagulant and platelet antiaggregant medications as patients with less severe epistaxis. Overall, on univariate logistic regression analysis, no factors were independently associated with severity of epistaxis. The pathophysiology of serious spontaneous epistaxis remains to be unclear. It concerns elderly patients (>60-70 years old) with a history of hypertension in about 50% of cases. Serious spontaneous epistaxis may also be the presenting sign of underlying true hypertension in about 43% of patients with no history of hypertension. However, hypertension per se does not appear to be a statistically significant causal factor and/or a factor of severity of serious spontaneous epistaxis. © 2011 Springer-Verlag.

According to the amyloid theory, the appearance of amyloid-β (Aβ) deposits represents a pivotal event in late onset Alzheimer's disease (LOAD). Physiologically, Aβ 42 monomers are cleaned by capillary resorption, enzymatic catabolism, and cerebrospinal fluid (CSF) transport. Factors that promote the oligomerization of Aβ 42 must be specified. In vitro, these monomers spontaneously form neurotoxic oligomers whose rate increases with time suggesting that the stasis of CSF favors the oligomerization. In animals, experimental hydrocephalus generates CSF stasis followed by the appearance of amyloid deposits. In normal pressure hydrocephalus, amyloid deposits are common, especially in elderly patients, and the turnover decline has the same order of magnitude as in AD. In this disease, the effects of CSF stasis are potentiated by the decline in the ability of CSF to inhibit the formation of oligomers. CSF originates from choroid plexus (CP). In LOAD, the functions of secretion, synthesis, and transport of CP are impaired and this is related to morphological modifications. These impairments favor the decrease of CSF turnover, the diminished levels of transthyretin, a sequestering protein synthesized by CP, and the oligomerization of Aβ 42. They are potentiated by a reduced enzymatic catabolism and a decreased capillary reabsorption of Aβ 42, both alterations being related to age. © 2012-IOS Press and the authors. All rights reserved.
