A ten-year follow-up of the Reflection cementless acetabular component.
2008
We reviewed the long-term results at ten to 12 years of 118 total hip replacements in 109 patients using a second-generation hemispherical cementless acetabular component (Reflection) designed to address the problem of backside wear. Five patients (five hips) died and six patients (seven hips) were lost to follow-up. The remaining 98 patients (106 hips) had a mean age of 62.9 years (34.0 to 86.2) A rate of revision for aseptic loosening of 0.9%, and predictable results were found with respect to radiological evidence of fixation, lack of pain, walking ability, range of movement and function. One component was revised for aseptic loosening, and of the 101 hips (95.2%) that did not have a rev…
Cementless acetabular reconstruction and structural bone-grafting in dysplastic hips. Surgical technique.
2007
BACKGROUND: Studies of acetabular reconstruction with use of cement and bulk bone graft have demonstrated increasing rates of cup failure in patients with dysplastic hips seven years after total hip arthroplasty. Comparable data on the long-term results of bulk bone-grafting done in conjunction with cementless implants are limited. The aim of this study was to review the clinical and radiographic results of autologous bulk bone-grafting in conjunction with a cementless cup. METHODS: From 1987 to 1992, forty-seven patients (forty women and seven men, with an average age of 50.4 years) who had developmental dysplasia of the hip underwent fifty-six total hip arthroplasties and received a struc…
Retrograde Transpubic Screw Fixation
2017
In the vast majority of fragility fractures of the pelvis, fractures of the posterior and anterior pelvic ring occur combined. Fractures of the pubic rami above and below the obturator foramen are much more frequent than fractures of the pubic bone and fractures at the anterior lip of the acetabulum. Retrograde transpubic screw fixation is a minimally invasive technique for stabilization of pubic rami fractures. The anterior column corridor is a straight corridor between the anterior cortex of the superior pubic ramus near to the pubic tubercle and the external cortex of the ilium above the acetabulum. The minimal canal diameter, measured in 160 Japanese, was on average 13.5 mm for men and …
Impingement of the Sciatic Nerve due to a Protruding Acetabular Cage Rim
2020
Abstract Sciatic nerve damage is a well-known complication that occurs in 1.5% of patients after primary total hip arthroplasty and in 8% after revision total hip arthroplasty. Yet when considering re-revision arthroplasty and acetabular cage implantation, incidence and management remain unclear. This case report describes a young female patient with sciatic nerve impingement after acetabular cage implantation. Her primary complaint was shooting sciatic left leg pain, worsening on ambulation and when seated. A complete workup was negative for spinal impingement or infection, and axonal nerve damage was confirmed through nerve conduction studies. The intraoperative findings showed that it wa…
Intra-articular corticosteroids versus intra-articular corticosteroids plus methotrexate in oligoarticular juvenile idiopathic arthritis: a multicent…
2017
Summary Background Little evidence-based information is available to guide the treatment of oligoarticular juvenile idiopathic arthritis. We aimed to investigate whether oral methotrexate increases the efficacy of intra-articular corticosteroid therapy. Methods We did this prospective, open-label, randomised trial at ten hospitals in Italy. Using a concealed computer-generated list, children younger than 18 years with oligoarticular-onset disease were randomly assigned (1:1) to intra-articular corticosteroids alone or in combination with oral methotrexate (15 mg/m 2 ; maximum 20 mg). Corticosteroids used were triamcinolone hexacetonide (shoulder, elbow, wrist, knee, and tibiotalar joints) o…
Levetiracetam‐induced pediatric toxic epidermal necrolysis successfully treated with etanercept
2020
Successful management of toxic epidermal necrolysis (TEN) with tumor necrosis factor-α inhibitors has been described in adults, but few cases have been reported in children. To date, only four pediatric cases of TEN treated with infliximab and one with etanercept have been published. We present the case of an 8-year-old boy diagnosed with TEN induced by levetiracetam, successfully treated with etanercept, systemic corticosteroids, and intravenous immunoglobulin.
Nesteroīdo pretiekaisuma līdzekļu aprite aptiekā
2020
Nesteroīdie pretiekaisuma līdzekļi (NPL) ir vispieprasītākā medikamentu grupa pasaulē. Galvenie iemesli NPL lietošanai ir sāpes, iekaisums un drudzis. Darba mērķis bija salīdzināt NPL pieprasījumu par 2017., 2018. un 2019. gadu, kā arī noskaidrot, kādas ir biežākās blakusparādības, ar kurām šo medikamentu lietošanas laikā sastopas respondenti. Darba uzdevumi bija izanalizēt NPL apgrozījumu vienā no SIA “Euro aptieka” tīkla aptiekām, kura atrodas Rīgā, Ziepniekkalna rajonā par 2017., 2018. un 2019. gadu, noskaidrot, kuri NPL medikamenti ir vispieprasītākie, noskaidrot, kādas ir visbiežākās blakusparādības respondentiem, noskaidrot, kādas sāpes biežāk piemeklē respondentus. Iegūtie dati lieci…
Role of acetaldehyde in alcohol addiction: current evidence and future perspectives
2011
The effects of alcohol have been widely studied during the past century, corroborating the idea that this tiny chemical compound acts throughout most of our neurotransmitter systems since it is capable of inducing addictive behaviour. Two of the most serious problems of alcohol addiction are craving and relapse; several studies have demonstrated that relapse is related to the anxious state which occurs during withdrawal, and it has been proved that this behavioural modifications results from an alteration of the dopaminergic and serotonergic systems. An important role in the neurobiology of alcohol addiction is played by acetaldehyde (ACD), ethanol first metabolite. Our recent studies indee…
Synthesis and Holographic Properties of Alkyl 2-Cyanoacetate Acceptor Fragment Containing Push – Pull Type Organic Glasses
2015
We present synthesis, optical and holographic properties of original structure organic glasses based on compounds consisting of three fragments: of N,N-bis(2-(trityloxy)ethyl)-4-vinylaniline or N,N-bis(5,5,5-triphenylpentyl)-4-vinylaniline fragments as electron donating fragment (D), 4H-pyran-4-ylidene fragment as linker(π) and of 2-(trityloxy)ethyl 2-cyanoacetate or 5,5,5-triphenylpentyl 2-cyanoacetate as acceptor (A) fragment. These push-pull (D- π-A) type molecular compounds show good solubility in non-polar solvents (CHCl3 or CH2Cl2) and neat thin films with sufficient optical qualities have been obtained by spin-coating technique. Maxima of UV–VIS absorption in dichloromethane solution…
An efficient method for selective oxidation of (oxime)Pt(II) to (oxime)Pt(IV) species using N,N-dichlorotosylamide
2016
The oxidation of (oxime)PtII species using the electrophilic chlorine-based oxidant N,N-dichlorotosylamide (4-CH3C6H4SO2NCl2) was studied. The reactions of trans-[PtCl2(oxime)2] (where oxime = acetoxime, cyclopentanone oxime, or acetaldoxime) with this oxidant led to trans-[PtCl4(oxime)2] products. The oxidation of trans-[Pt(o-OC6H4CH = NOH)2] at room temperature gave trans-[PtCl2(o-OC6H4CH = NOH)2], whereas the same reaction upon heating was accompanied by electrophilic substitution of the benzene rings. peerReviewed
