Total shoulder arthroplasty versus hemiarthroplasty for glenohumeral arthritis: A systematic review of the literature at long-term follow-up

Introduction:

The optimal surgical treatment of end-stage primary glenohumeral osteoarthritis remains controversial. The objective of this article is to systematically review the current available literature to formulate evidence-based guidelines for treatment of this pathology with an arthroplasty.

Materials and Methods:

A systematic literature search was performed to identify all articles from 1990 onward that presented data concerning treatment of glenohumeral arthritis with total shoulder arthroplasty (TSA) or head arthroplasty (HA) with a minimal follow-up of 7 years. The most relevant electronic databases were searched.

Results:

After applying the inclusion and exclusion criteria, we identified 18 studies (of the initial 832 hits). The search included a total of 1,958 patients (HA: 316 and TSA: 1,642) with 2,111 shoulders (HA: 328 + TSA: 1,783). The revision rate for any reason in the HA group (13%) was higher than in the TSA group (7%) (P < 0.001). There was a trend of a higher complication rate (of any kind) in the TSA group (12%) when compared with the HA group (8%) (P = 0.065). The weighted mean improvement in anteflexion, exorotation and abduction were respectively 33°, 15° and 31° in the HA group and were respectively 56°, 21° and 48° in the TSA group. Mean decrease in pain scores was 4.2 in the HA and 5.5 in the TSA group.

Conclusion:

Finally, we conclude that TSA results in less need for revision surgery, but has a trend to result in more complications. The conclusions of this review should be interpreted with caution as only Level IV studies could be included.

Level of Evidence:

IV.     

Influence of Preoperative and Postoperative Pelvic Floor Muscle Training (PFMT) Compared with Postoperative PFMT on Urinary Incontinence After Radical Prostatectomy: A Randomized Controlled Trial

Background

The efficacy of preoperative pelvic floor muscle training (PFMT) for urinary incontinence (UI) after open radical prostatectomy (ORP) and robot-assisted laparoscopic radical prostatectomy (RARP) is still unclear.

Objective

To determine whether patients with additional preoperative PFMT regain urinary continence earlier than patients with only postoperative PFMT after ORP and RARP.

Design, setting, and participants

A randomized controlled trial enrolled 180 men who planned to undergo ORP/RARP.

Intervention

The experimental group (E, n = 91) started PFMT 3 wk before surgery and continued after surgery. The control group (C, n = 89) started PFMT after catheter removal.

Outcome measurements and statistical analysis

The primary end point was time to continence. Patients measured urine loss daily (24-h pad test) until total continence (three consecutive days of 0 g of urine loss) was achieved. Secondary end points were 1-h pad test, visual analog scale (VAS), International Prostate Symptom Score (IPSS), and quality of life (King's Health Questionnaire [KHQ]). Kaplan-Meier analysis and Cox regression with correction for two strata (age and type of surgery) compared time and continence. The Fisher exact test was applied for the 1-h pad test and VAS; the Mann-Whitney U test was applied for IPSS and KHQ.

Results and limitations

Patients with additional preoperative PFMT had no shorter duration of postoperative UI compared with patients with only postoperative PFMT (p = 0.878). Median time to continence was 30 and 31 d, and median amount of first-day incontinence was 108 g and 124 g for groups E and C, respectively. Cox regression did not indicate a significant difference between groups E and C (p = 0.773; hazard ratio: 1.047 [0.768–1.425]). The 1-h pad test, VAS, and IPSS were comparable between both groups. However, “incontinence impact” (KHQ) was in favor of group E at 3 mo and 6 mo after surgery.

Conclusions

Three preoperative sessions of PFMT did not improve postoperative duration of incontinence.

Return to work after coronary artery bypass surgery. A 10-year follow-up study

Multislice Computed Tomography Coronary Angiography (CTCA) has emerged as a promising non-invasive modality for the detection of coronary artery stenosis. Image quality is still limited when compared to conventional coronary angiography. However, CTCA has been demonstrated to be highly reliable to rule out coronary artery stenosis. Technological improvements and the combination of CTCA with other non-invasive modalities are expected to further increase diagnostic accuracy. Although CTCA has clearly left the research environment, the precise role of CTCA in the diagnostic work-up of coronary artery disease needs further research.     

Coital frequency and condom use in monogamous and concurrent sexual relationships in Cape Town,South Africa

Introduction

A decreased frequency of unprotected sex during episodes of concurrent relationships may dramatically reduce the role of concurrency in accelerating the spread of HIV. Such a decrease could be the result of coital dilution – the reduction in per-partner coital frequency from additional partners – and/or increased condom use during concurrency. To study the effect of concurrency on the frequency of unprotected sex, we examined sexual behaviour data from three communities with high HIV prevalence around Cape Town, South Africa.

Methods

We conducted a cross-sectional survey from June 2011 to February 2012 using audio computer-assisted self-interviewing to reconstruct one-year sexual histories, with a focus on coital frequency and condom use. Participants were randomly sampled from a previous TB and HIV prevalence survey. Mixed effects logistic and Poisson regression models were fitted to data from 527 sexually active adults reporting on 1210 relationship episodes to evaluate the effect of concurrency status on consistent condom use and coital frequency.

Results

The median of the per-partner weekly average coital frequency was 2 (IQR: 1–3), and consistent condom use was reported for 36% of the relationship episodes. Neither per-partner coital frequency nor consistent condom use changed significantly during episodes of concurrency (aIRR=1.05; 95% confidence interval (CI): 0.99–1.24 and aOR=1.01; 95% CI: 0.38–2.68, respectively). Being male, coloured, having a tertiary education, and having a relationship between 2 weeks and 9 months were associated with higher coital frequencies. Being coloured, and having a relationship lasting for more than 9 months, was associated with inconsistent condom use.

Conclusions

We found no evidence for coital dilution or for increased condom use during concurrent relationship episodes in three communities around Cape Town with high HIV prevalence. Given the low levels of self-reported consistent condom use, our findings suggest that if the frequency of unprotected sex with each of the sexual partners is sustained during concurrent relationships, HIV-positive individuals with concurrent partners may disproportionately contribute to onward HIV transmission.     

Executive functions in borderline personality disorder

Different domains of executive function such as working memory and response inhibition were investigated together with elementary cognitive processes in borderline personality disorder (BPD). Patients with BPD (N=28) were compared to nonpatient controls (NP, N=28) on eight tasks (e.g. n-back, Go/NoGo, CPT-AX). In order to separate impairments in different cognitive domains and to assess the influence of more elementary cognitive processes on executive functioning, tasks were embedded in a reaction-time-decomposition approach. BPD patients solved tasks with accuracies comparable to those of nonpatients. The only exception was the n-back task, for which working memory is required: here, error rates were higher and increased more prominently in BPD patients depending on working memory load. In most tasks, movement times were shorter for BPD patients than for nonpatients, while the quality of task-solving was comparable. The faster processing in the BPD group was observable starting with the simplest task, i.e. a simple reaction-time task. These findings suggest that domains of executive functioning are differentially affected in BPD. In contrast to load-dependent deficits in working memory, response inhibition processes were unimpaired. Faster action-related processes could be observed in BPD patients in a variety of tasks; however, these did not influence executive functioning.
