Parestomal hernia repair. Prospective observational research based on the The spanish language Pc registry associated with Incisional Hernia (EVEREG).
(1) To determine the rate of return to play following autologous osteochondral transplantation (AOT) for osteochondral lesions of the talus (OLT) and (2) report subsequent rehabilitation protocols.

A systematic review of the PubMed, Embase, and The Cochrane Library databases was performed according to the PRISMA guidelines based on specific eligibility criteria. Return to play data was meta-analysed and subsequent rehabilitation protocols were summarised. Level of evidence and quality of evidence (Zaman's criteria) were also evaluated.

Nine studies that totalled 205 ankles were included for review. The mean follow-up was 44.4 ± 25.0 (range 16-84) months. The mean OLT size was 135.4 ± 56.4mm
. The mean time to return to play was 5.8 ± 2.6months. The mean rate of return to play was 86.3% (range 50-95.2%), with 81.8% of athletes returning to pre-injury status. Based on the fixed-effect model, the rate of return to play was 84.07%. Significant correlation was found between increase age and decrease rate of return to play (R
 = 0.362, p = 0.00056). There was no correlation between OLT sizes and rate of return to play (R
 = 0.140, p = 0.023). The most common time to ankle motion post-surgery was immediately and the most common time to full weight-bearing was 12weeks.

This systematic review indicated a high rate of return to play following AOT in the athletic population. Size of OLT was not found to be a predictor of return to play, whereas advancing age was a predictor. Rehabilitation protocols were largely inconsistent and were primarily based on individual surgeon protocols. However, the included studies were of low level and quality of evidence.

To examine diagnostic and therapeutic utility of novel ultrasound-guided perineural injection of posterior antebrachial cutaneous nerve in chronic lateral elbow pain.

We performed a retrospective analysis of ultrasound-guided perineural injection of the posterior antebrachial cutaneous nerve with local anesthetic with or without corticosteroid in patients with chronic lateral elbow pain. Data variables collected included patient demographics, illness course, diagnostic ultrasound findings, immediate pre- and post-injection pain using numeric rating pain scale between 0 and 10, injection complications, and post-injection outcomes.

Fifteen patients (9 females and 6 males) with average age 46.9 (range 16-69years) underwent 20 perineural injections between 2009 and 2019. Patients had on average 84% reduction in pain immediately after the injection (median pre- and post-procedure numeric rating pain scale of 6 and 0, respectively, p < 0.001). Patients had pain relief for an average of 15h (range 2-48h) when only local anesthetic was injected, compared with average pain relief of 26.5days (range 2h-43days) when local anesthetic was combined with corticosteroid, p = 0.01.

Novel ultrasound-guided perineural anesthetic injections around the posterior antebrachial cutaneous nerve can be performed safely and have diagnostic and potentially therapeutic utility in select patients with chronic refractory lateral elbow pain.

Within the framework of the current study, a novel vertical flow constructed wetland system was implemented for greywater treatment in four different rural areas in Jordan. In this paper, the primary objective was to develop a regression-based nonlinear model to predict BOD effluent concentration from the proposed system. The model obeyed the first-order kinetics and found to provide an efficient tool in predicting the effluent BOD value as exemplified by an R2 of 0.78. Moreover, a cost analysis was carried out to verify the feasibility of the proposed system. The economic results revealed a NPV range of 295-1209 JOD (420-1730$), IRR range of 6-10.7%, and a payback period range of 8.8-15.5 years. The average calculated costs of greywater treatment using the VFCWs were found to be 0.391 (USD/m3 treated) and 0.672 (USD/kg BOD removed).

To report and analyse factors affecting the outcome of streptococcal periprosthetic joint infections (PJIs).

A retrospective analysis of consecutive streptococcal PJIs was performed. Musculoskeletal Infection Society 2013 criteria were used. Outcome was compared with a prospective PJI cohort from the same institution.

The most common isolated streptococcal species was Streptococcus dysgalactiae (9/22, 41%) among 22 patients included. Surgical treatment consisted of DAIR (debridement, antibiotics, irrigation and retention) in 12 (55%), one-stage revision arthroplasty in one (4%), two-stage revision arthroplasty in eight (37%) and implant removal in one (4%) patient. An infection free-outcome was achieved in 15 cases (68%), whilst seven (32%) patients failed initial revision and relapsed with the same pathogen, from which six were treated with DAIR and one with one-stage revision arthroplasty. No failures were observed in patients who received a two-stage revision. Failure rates did not differ in the cases treated with rifampin (1/5) from those without 6/17 (p = 0.55). There was no correlation between the length of antibiotic treatment and relapse (p = 0.723). In all failures, a persistent distant infection focus was identified at the time of relapse. Compared with our prospective PJI cohort, relapse rates were significantly higher 32% vs 12% (p < 0.05).

No correlation with the use of rifampin or length of antibiotic treatment was found. No failures were observed in patients who received a two-stage revision, which may be the surgical treatment of choice. A distant persisting infection focus could be the reason for PJI relapse with recurrent hematogenous seeding in the joint.
