goscope with Macintosh blade. The implementation could lower the incidence of subjective difficult airways.The Canadian Critical Care Society performed a meta- analysis to assess the benefits and risks of the application of vasopressin and vasopressin- analogues in distributive shock. Their results were formulated as a Guideline in 2019. In the meta- analysis mainly included were studies with patients suffering from sepsis causing the distributive shock. The recommendations of the Surviving Sepsis Campaign 2016 concerning catecholamine therapy clearly prefer norepinephrin as the first- choice vasopressor, the use of vasopressin as an additionally administered drug is rated more tentative. Also the Canadian guideline now, implicating recently published studies, argues for the use of vasopressin or vasopressin- analogues in addition to an existing norepinephrine therapy, even though the level of evidence remains still low and there's no simple therapeutic algorithm formulated. This is based on a lowered incidence of newly- diagnosed atrial fibrillation and decreased mortality rate while administration remains safe.BACKGROUND In recent years, ultrasound (US) has become more incorporated into anesthesia and intensive care medicine. The German Anesthesia Society established a modular curriculum to teach US skills. Until now, the efficacy of this modular curriculum has not been validated. OBJECTIVE The main objective of this study was to determine whether there is an increase of knowledge and of psychomotor skills for the trainees in this curriculum. MATERIAL AND METHODS After ethical committee approval, 41 anesthesia physicians were enrolled. To determine the increase of knowledge and of practical skills theoretical and practical tests performed were evaluated before and after two different US courses. RESULTS Comparing before and after course tests, the participants showed significant improvement in theoretical multiple choice tests (p = 0.008). Regarding psychomotor skills following course 1, the trainees improved significantly in the time needed to perform the two practical tests (p = 0.03), but not in the performance of the test. Better needle visualization during simulated US-guided vessel puncture (p = 0.52) and better identification of the anatomical structures in the axillary region (p = 0.56) could not be achieved. CONCLUSION This study shows that although this US course curriculum has positively enhanced the trainees' theoretical knowledge of US practice, it does not enhance the practical application of that theoretical knowledge. To improve this curriculum, a supervised clinically practical training should follow the course.PURPOSE To assess the natural evolution of the osseous reaction following arthroscopic double-row rotator cuff repair with PEEK anchors and to analyze its correlation with clinical shoulder function. METHODS Between 2015 and 2017, 159 patients received arthroscopic double-row rotator cuff repair with PEEK anchors and underwent serial clinical and radiological follow-up (3, 6, 12, and 24 months). Radiological results were analyzed by tendon integrity, bone marrow edema, and peri-implant osteolysis. selleckchem Clinical shoulder function was evaluated with the Constant score. RESULTS One-hundred and seventeen patients were enrolled; among them, 63% demonstrated bone marrow edema around the anchors on postoperative 3-month MRI. The edema area percentage was 41% ± 7%. At 6 months, edema was only seen in 12% of cases, with an area percentage of 18% ± 5%. At 12 and 24 months, edema was rarely present. Fluid signals around the anchor were observed in 17.6%, 42.7%, 33.3%, and 21.0% of patients at 3, 6, 12, and 24 months, respectively; the tunnel widening values were 1.1 ± 0.4 mm, 1.8 ± 0.5 mm, 2.3 ± 0.6 mm, and 2.2 ± 0.7 mm at each follow-up, respectively. The sign of osteolysis was significantly more obvious around the lateral anchor than around the medial anchor. The presence of an osseous reaction was not correlated with worse clinical outcome. CONCLUSION Osseous reactions following arthroscopic rotator cuff repair are common and significant even with PEEK anchors. Bone marrow edema does not last more than 6 months in patients without complications. Peri-implant osteolysis is more evident around the lateral anchor than around the medial anchor and improves gradually over time. The sign of osteolysis is not correlated with clinical shoulder function. Based on these findings, surgeons should be cautious about bone marrow edema lasting more than 6 months following arthroscopic rotator cuff repair. LEVEL OF EVIDENCE Level IV.PURPOSE The purpose of this systematic review and meta-analysis was to evaluate the correlation between the incidence of herniation pits (HPs) and femoroacetabular impingement (FAI)-related morphologies. METHODS A systematic search of the MEDLINE, EMBASE, and Cochrane Library databases was performed for studies evaluating the relationship between the incidence of HPs and FAI-related morphologies published up to August 16, 2019. Subgroup analyses were also performed to determine the differences in the relationship between the presence/absence of hip symptoms and cam-/pincer-type FAI. RESULTS Seven studies involving 7950 hips were included. The pooled odds ratio (OR) for the incidence of HPs in the presence of an FAI-related morphology was 1.64 (95% confidence interval [CI] = 1.09-2.46; P = 0.02). In the subgroup analyses, the ORs for the incidence of HPs in the symptomatic and asymptomatic hips were 1.00 (95% CI 0.40-2.51; P = 1.00) and 1.59 (95% CI 1.42-1.77; P  less then  0.0001), respectively; the ORs for the incidence of HPs in the cam- and pincer-type FAI were 1.61 (95% CI 1.43-1.81; P  less then  0.0001) and 1.42 (95% CI 0.77-2.61; P = n.s.), respectively. CONCLUSIONS The incidence of HPs has a significant relationship with FAI-related morphology, especially in asymptomatic patients and those with cam-type FAI morphology. LEVEL OF EVIDENCE III.PURPOSE Modern total knee arthroplasty (TKA) systems are designed to reproduce the normal knee kinematics and improve patient outcome. The authors compared two different third-generation medial pivot TKA implants, having a single-radius or a J-curve design in their sagittal plane, hypothesizing no clinical differences. METHODS Two cohorts of 50 patients who underwent primary TKA were first preoperatively matched by sex, deformity, body mass index (BMI), Oxford Knee Score (OKS), Knee society score (KSS) and range of motion (ROM) and then statistically analyzed at a minimum follow-up (FU) of 2 years. An identical surgical technique, which aimed to reproduce a slightly tighter medial than lateral compartment, was used in all knees. RESULTS At a minimum follow-up of 2 years (range 24-34 months) there were no statistically significant differences in OKS and KSS between the two implant groups. The final ROM differed statistically between the two groups the average maximum active flexion was 123° in the J-curve femoral design group with an adapted "medially-congruent" polyethylene insert, and 116° in the single radius femoral design with a medial "ball-in-socket" articulation.
