Here, we established an MRI-based staging system for lymphedema and validate it against existing clinical measures. METHODS Bilateral upper extremity MRI and lymphoscintigraphy were performed on 45 patients with unilateral secondary lymphedema, due to surgical intervention, who were referred to our multidisciplinary lymphedema clinic between March 2017 and October 2018. MRI short-tau inversion recovery (STIR) images were retrospectively reviewed. A grading system was established based on the cross-sectional circumferential extent of subcutaneous fluid infiltration at three locations, labeled MRI stage 0-3, and was compared to L-Dex®, ICG lymphography, volume, lymphedema quality of life (LYMQOL), International Society of Lymphology (ISL) stage, and lymphoscintigraphy. Linear weighted Cohen's kappa was calculated to compare MRI staging by ompared to lymphoscintigraphy and evaluation by lymphedema specialists. selleck chemicals • MRI-based staging of secondary upper extremity lymphedema is highly reproducible and could be used for long-term follow-up of patients. • In patients with borderline clinical measurements, MRI can be used to identify patients with early-stage lymphedema.OBJECTIVE To develop imaging guidelines for the MR work-up of female genital tract congenital anomalies (FGTCA). METHODS These guidelines were prepared based on a questionnaire sent to all members of the European Society of Urogenital Radiology (ESUR) Female Pelvic Imaging Working Group (FPI-WG), critical review of the literature and expert consensus decision. RESULTS The returned questionnaires from 17 different institutions have shown reasonable homogeneity of practice. Recommendations with focus on patient preparation and MR protocol are proposed, as these are key to optimised examinations. Details on MR sequences and planning of uterus-orientated sequences are provided. CONCLUSIONS The multiplanar capabilities and soft tissue resolution of MRI provide superb characterisation of the wide spectrum of findings in FGTCA. A standardised imaging protocol and method of reporting ensures that the salient features are recognised, contributing to a correct diagnosis and classification of FGTCA, associated anomalies and complications. These imaging guidelines are based on current practice among expert radiologists in the field and incorporate up to date information regarding MR protocols and essentials of recently published classification systems. KEY POINTS • MRI allows comprehensive evaluation of female genital tract congenital anomalies, in a single examination. • A dedicated MRI protocol comprises uterus-orientated sequences and vaginal and renal evaluation. • Integration of classification systems and structured reporting helps in successful communication of the imaging findings.INTRODUCTION Results of iterative ACL reconstructions are lower than after primary reconstructions. Our aim was to report the results of a retrospective series of revision using pedicled quadruple hamstring autograft. The hypothesis was that the results were satisfactory and comparable to the literature. METHODS The study period was from January 2012 to December 2014. Fourteen patients (average age 26) were included. A fascia lata graft was used 12 times for primary reconstruction. Trauma was the cause of failure 12 times. The time interval between primary reconstruction and revision was 6.2 years. Preoperative scores used were LYSHOLM, TEGNER and IKDC. Sagittal stability was measured using the KT-1000 device. X-rays and MRI were performed to confirm the diagnosis, look for preoperative osteoarthritis and evaluate the position of the bony tunnels (Bernard and Hertel). Bone tunnels were in a proper position 14 times. RESULTS At 45-month follow-up, improvement of objective IKDC score was significant (85.7% A/B, p  0.5), and the average TEGNER score was 5.5 (p = 0.003). The Lachman test found a hard stop in all patients. The pivot shift test was negative for 78.5% of the cases. The laxity measurement found 12 cases with less than 3 mm. One persistent distal hypoesthesia at 2-year follow-up was observed. CONCLUSION The hypothesis was confirmed. This series differs by the cause of failure, which was essentially traumatic, and the initial predominance of a fascia lata graft. These results remain to be confirmed. LEVEL OF EVIDENCE Retrospective case series, level IV.PURPOSE This study examined the outcomes and complications after treatment of unstable distal clavicle fractures with hook or locking plate fixation. METHODS A retrospective search was performed of all acute distal clavicle fractures treated with open reduction and internal fixation from 2009 to 2019 at a Level I trauma center. Patients were separated into hook and locking plate fixation groups. Rates of union, complications, and reoperation, were extracted. QuickDASH (Disabilities of Arm, Shoulder, and Hand) scores were determined. RESULTS Thirty-one patients met the inclusion criteria and were included in the study. Of these, 12 patients were treated with hook plates and 19 were treated with locking plates. All fractures healed without loss of reduction, regardless of implant selection. There were no immediate or long-term complications in either group. 83% of hook plate patients underwent planned implant removal, while 37% of locking plate patients requested implant removal secondary to irritation. QuickDASH scores were comparable and excellent in both groups. CONCLUSIONS Hook and locking plate fixation for Neer type-II and type-V distal clavicle fractures have comparably high rates of union. Hook plates were removed routinely per protocol, while locking plates were removed only if symptomatic and occurred significantly less often.PURPOSE The purpose of this study is to compare the temporal processing performance of children with cochlear implant (CI) according to the age of implantation and to determine their relation with auditory perception scores. METHODS In this study, 30 cochlear implant users and ten normal hearing children at 9 and 10 years were included. Children with cochlear implants are divided into two groups according to the age of implantation group I includes participants whose implantation age is between 13 and 35 months (20 children), group II includes participants whose implantation age is between 36 and 45 months (10 children). Individuals were evaluated with random gap detection test (RGDT), duration pattern test (DPT), frequency pattern test (FPT), the Mr. Potato Head task, word recognition, and sentence recognition test. RESULTS A significant difference was found between the control and CI groups in temporal processing performance. The temporal processing ability of CI groups was significantly worse than those of normal hearing.
