BACKGROUND: The most common causes of pain following lumbar spinal fusions are residual herniation, or foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. The original surgeon may advise his patient that nothing more can be done in his opinion that the nerve was visually decompressed by the original surgery. Post-operative imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of failed lumbar spinal fusions by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain...

BACKGROUND: Patellar tendon chronic ruptures are more debated to manage that acute injuries as the patella tends to retract proximally (after 2 weeks), and surrounding soft tissues may make the repair more complicate. PURPOSE: We propose a novel technique in which the patellar tendon is reconstructed using ipsilateral hamstring tendons. This surgical procedure implies to drill a single tunnel through the patella and another through the tibia to reduce the risk of bony breakage...

Catheter-related infections in peritoneal dialysis (PD) remain a significant complication, and some patients with recurrent exit-site (ESI) and/or tunnel infections may experience external cuff extrusion. In these cases, cuff-shaving has been described as a possible course of treatment. During a 4-year period, there were 44 patients with PD at our department; all received double-cuffed Tenckhoff catheters. Six (13%) never started on PD. Five (13%) of the 38 active PD patients experienced cuff extrusion. Causes of end-stage renal disease (ESRD) were diabetic nephropathy (n = 1), toxic nephropathy (n = 1), hypertensive nephrosclerosis (n = 1), systemic disease (n = 1) and one with unknown cause...

Enteric viruses are released in important quantities into the environment where they can persist for a very long time. At very low doses, they can cause human gastroenteritis, and are responsible for a substantial number of waterborne diseases. The aims of this study were multiple: firstly, to study the circulation of Aichi viruses (AiV) in wastewater sampled at the scale of a pilot wastewater treatment plant; secondly, to evaluate the performance of two wastewater treatment procedures, as natural oxidizing lagoons and rotating Biodisks, concerning the AiV removal; and finally, to determine the different type of AiV genotype found during this study...

INTRODUCTION: According to the WHO, abortion accounts for about 8% (4.7-13.2) of maternal mortality worldwide. In 2010, the WHO Multi-Country Survey (MCS) on Maternal and Newborn Health collected data on over 300 000 women who were admitted in health facilities to receive pregnancy-related care. Abortion data were partially captured by centring on severe maternal outcomes (ie, near-miss or maternal deaths). Building on the experiences of the prior MCS as well as current WHO reproductive health projects, we are undertaking a multi-country survey to better capture the burden and severity of abortion-related complications and management among women presenting to the health facilities...

This multi-centre study assessed operating room (OR) staff compliance with clothing regulations and traffic flow during surgical procedures. Of 1615 surgical attires audited, 56% respected the eight clothing measures. Lack of compliance was mainly due to inappropriate wearing of jewellery (26%) and head coverage (25%). In 212 procedures observed, a median of five people [interquartile range (IQR) 4-6] were present at the time of incision. The median frequency of entries to/exits from the OR was 10.6/h (IQR 6-29) (range 0-93)...

Many operating room (OR) processes can limit productivity. Surprisingly, little has been done to identify which OR processes limit downstream activities. Here, the authors aimed to review their burn OR procedures to determine if and where inefficiencies exist. Data for all operations performed in a dedicated burn OR from January 1, 2015, to July 31, 2016 were reviewed in the electronic medical records of our public, teaching hospital. The total time spent was allocated into the following components: induction (patient in room to end of induction), preparation (end of induction to procedure start), procedure (procedure start to procedure end), exit (procedure end to patient out of room), and turnover (patient out of room to next patient in room)...

RATIONALE: Production of multiply protonated ions by electrospray ionization (ESI) is important to the analysis of peptides by mass spectrometry. For small neutral and acidic peptides, addition of chromium(III) greatly increases the intensity of doubly protonated ions. The current study examines instrumental and solution parameters that maximize peptide ion charge by ESI. METHODS: The neutral and basic heptapeptides AAAAAAA (A7) and AAAKAAA (A3KA3) were used as test compounds and electrosprayed from a solution containing chromium(III) nitrate at a peptide to metal molar ratio of 1:10...
