ObjectiveThis study was performed to assess the outcomes of Asian patients who underwent conversion from metal-on-metal total hip arthroplasty (MoM-THA) to cemented THA (CTHA).MethodsOne hundred and fifty-seven consecutive patients (157 hips) who underwent CTHA following primary MoM-THA from January 2005 to February 2015 were retrospectively analysed. The primary endpoints were the clinical outcomes. Follow-ups occurred at 3 months, 6 months, 1 year, 2 years, and then every 2 years following revision of MoM-THA.ResultsThe mean follow-up after conversion was 10 years (range, 5–14 years). Statistically significant improvements in the mean Harris hip score were observed between the preoperative and final follow-up evaluations (62.71 ± 13.85 vs. 84.03 ± 16.21, respectively). The major orthopaedic complication rate was 16.5% (26/157). Six (3.8%) patients underwent revision at a mean of 3.5 ± 1.3 years after conversion, predominantly because of prosthesis loosening or recurrent dislocation. Nine (5.7%) patients developed prosthesis loosening at a mean of 2.6 ± 1.1 years following conversion, two of whom requested revision surgery. Eleven (7.0%) patients developed prosthesis dislocation, four of whom requested revision surgery.ConclusionCTHA may yield favourable functional outcomes and a reduced rate of major orthopaedic complications. 相似文献

Introductionfor a proportion of patients with functional motor symptoms (FMS), specific physiotherapy has recently emerged as a promising treatment. Aim of the present study was to assess in a sample of patients with FMS the efficacy of a physical therapy-based telemedicine programme on the motor symptoms themselves and on some psychological variables such as anxiety, depression, alexithymia and quality of life.Materials and methodseighteen patients were recruited. The programme consisted of 24 sessions: three face-to-face sessions (at week 0 (T0), 12 (T1) and 24 (T2)) and 21 tele-sessions. Each session included education, movement retraining exercises and development of a management plan. All patients underwent the following assessment at T0, T1 and T2: Psychogenic movement disorders rating scale (PMDRS), assessment of depression, anxiety, alexithymia and quality of life. Self-assessment of outcome (CGI) was recorded at T1 and T2.ResultsOn the CGI improvement was reported by 66,7% of patients at T1 and 77,8% at T2. A significant improvement over the three time points was shown for PMDRS and for the following domains of the SF-36: general health, vitality, social functioning and mental health.Conclusionthe use of two innovative approaches for FMS (physiotherapy and telemedicine), combined together, might have a valuable role in the treatment of this neuropsychiatric condition. 相似文献

目的 探讨经腹腔镜逆行胆囊切除术(laparoscopic retrograde cholecystectomy,LRC)治疗复杂胆囊结石(complicated gallbladder stones,CGS)中转开腹的相关危险因素,构建预测列线图并进行验证。方法 选取2016年9月至2019年3月青海红十字医院行LRC治疗CGS的病人380例作为训练集,2019年4月至2021年9月该院行LRC治疗CGS的病人350例作为验证集,训练集依据术中是否中转开腹分为中转组(34例)和非中转组(346例)。单因素分析两组病人的临床病理特征,logistic多元回归模型分析经LRC治疗CGS中转开腹的危险因素,基于该多因素logistic回归模型,构建中转开腹的列线图,并对其进行外部验证以及绘制校正曲线。结果 训练集与验证集两组一般资料比较,各临床因素组间均差异无统计学意义(P>0.05);单因素分析显示训练集中中转组与非中转组在身体质量指数(body mass index,BMI)、上腹部手术史、糖尿病、胆囊颈结石、胆囊增大、胆囊炎发作时间、胆囊壁增厚、结石数量、白蛋白、白细胞计数(w... 相似文献

ObjectiveThe objective of this study was to compare whether different sources of cognitive complaint (i.e., subjective and informant) predict diagnostic conversion in nondemented older adults.MethodsParticipants from the National Alzheimer's Coordinating Center had a baseline diagnosis of normal cognition (NC; n = 4414; mean age, 73 ± 8 years; 69% female) or mild cognitive impairment (MCI; n = 1843; mean age, 74 ± 8 years; 52% female). Multinomial logistic regression related baseline cognitive complaint (no complaint, self only, informant only, or both self and informant) to diagnostic outcome (reversion, stable, or conversion).ResultsAt follow-up, 14% of NC participants converted to MCI/dementia (3.5 ± 1.8 years), and 41% of MCI participants converted to dementia (3.0 ± 1.6 years). Among NC participants, self complaint only (odds ratio [OR], 2.1; 99% confidence interval (CI),1.5–2.9; P < .001), informant complaint only (OR, 2.2; 99% CI, 1.2–3.9; P < .001), and both self and informant complaint (OR, 4.2; 99% CI, 2.9–6.0; P < .001) were associated with diagnostic conversion compared with no complaint. Among participants with MCI—compared with no complaint, informant complaint only (OR, 2.2; 99% CI, 1.2–4.3, P = .002), and both self and informant complaint (OR, 2.9; 99% CI, 1.8–4.8; P < .001)—were associated with conversion.ConclusionsCognitive complaints are related to conversion among nondemented older adults. Complaint from both (i.e. mutual complaint) sources was most predictive of diagnostic outcome, followed by informant complaint, highlighting the need for obtaining informant corroboration to enhance prognosis and distinguish underlying pathological processes from normal cognitive aging. Self complaint was related inconsistently to diagnostic outcome. 相似文献
