The scaphoid is the most commonly fractured carpal bone in adults as well as in children. Previous studies have reported a wide range of fracture incidences. Scaphoid fractures and non-unions in children have been sparsely investigated.

To perform a systematic review of the current literature on epidemiology of scaphoid fractures and non-unions in adults and children.

An electronic literature search was conducted investigating all studies in the literature published between January 1989 and June 23 2020. The systematic review following the PRISMA guidelines and searching in PubMed, Embase, Web of Science and Cochrane library databases was done in June 2020.

42 studies met our inclusion criteria, 6 studies were prospective, 32 were retrospective and 4 were register studies. The majority of studies relied on conventional radiographs for diagnosis. Scaphoid fractures in adults are predominately found in males with a peak incidence in the age group from 20 to 29 years. Incidence rates in males are reporte, evidence on epidemiology for scaphoid fractures and non-unions are low.

 The aim of this study was to evaluate the hepatorenal index ratio of Supersonic Imagine (B-mode ratio) and the controlled attenuation parameter (CAP) of FibroScan for the noninvasive diagnosis and grading of steatosis.

 Two centers prospectively included patients who underwent liver biopsy, B-mode ratio and CAP evaluation all on the same day between June 2017 and July 2019. MRI and histological morphometry were also performed in center 1. Histology (classic semiquantitative score and morphometry) was used as the reference.

 Concerning the B-mode ratio, the AUROCs for ≥ S1, ≥ S2 and ≥ S3 were respectively 0.896 ± 0.20, 0.775 ± 0.30 and 0.729 ± 0.39 with the best cut-off values being 1.22 for ≥ S1 (Se = 76.4 %, Sp = 93.2 %), 1.42 for ≥ S2 (Se = 70.2 %, Sp = 71.2 %) and 1.54 for ≥ S3 (Se = 68.4 %, Sp = 69.8 %). The correlation between the B-mode ratio and morphometry was moderate (Rs = 0.575, p < 0.001) and the correlation between the B-mode ratio and MRI was good (Rs = 0.613, p < 0.001). Concerning the CAP, the AUROCs for ≥  S1, ≥ S2 and ≥ S3 were 0.926 ± 0.18, 0.760 ± 0.30 and 0.701 ± 0.40, respectively, with the best cut-off values being 271 dB/m for ≥ S1 (Se = 84 %, Sp = 88.2 %), 331 dB/m for ≥ S2 (Se = 64.5 %, Sp = 74.7 %) and 355 dB/m for ≥ S3 (Se = 55.3 %, Sp = 75.1 %). The correlation between the CAP and morphometry and between the CAP and MRI was moderate in both cases (Rs = 0.526, p < 0.001 and Rs = 0.397, p < 0.001, respectively). SU5402 The B-mode ratio was better at ruling in and the CAP was better at ruling out the disease.

 B-mode ratio and CAP show similar and good performance for the diagnosis of steatosis (≥ S1). However, both techniques are limited with respect to differentiating mild to moderate (≥ S2) or severe (≥ S3) steatosis.

 Diagnosis of pulmonary embolism using V/P-SPECT may include the application of advanced image-processing techniques to identify V/P-mismatches. Aim of this study was to evaluate the benefit in clinical decision making in the diagnosis of pulmonary embolism.by whether adding to conventional reading a software that automatically calculates and visualizes the ventilation/perfusion-quotient pixel by pixel.

 63 consecutive patients with a clinical suspicion of PE who underwent V/P-SPECT were included in this retrospective study. Images were randomly ordered both for standard as well as for software-assisted reading using V/P-quotients. Studies were read independently by 2 experienced and 2 inexperienced raters. Diagnostic performance and observer agreement of all readers and both reading methods were determined.

 Expert observers consistently achieved a high diagnostic accuracy both in conventional as well as in software-assisted reporting (sensitivity 0.94 vs. 0.94, specificity 0.96vs. 0.97, LR

 Microsurgery fellowship applicants make decisions for future training based on information obtained from colleagues, mentors, and microsurgery fellowship program Websites (MFWs). In this study, we sought to evaluate the accessibility and quality of available information by microsurgery programs by analyzing the most commonly used web resources and social media outlets for applicants.

 The San Francisco (SF) Match and American Society of Reconstructive Microsurgery Websites were queried in April 2020 for microsurgery fellowship programs (MFPs) participating in the SF Match. Twenty-two independent variables of information were assessed on MFWs based on previously published data. Social media presence was also assessed by querying Facebook, Instagram, and Twitter for official hospital, plastic surgery residency, and microsurgery fellowship accounts.

 All 24 MFWs participating in the SF Match had a webpage. Program description, faculty listing, operative volume, and eligibility requirements were listed forquality of information available to applicants are limited, which is a missed opportunity for recruitment.

 As the field of microsurgery continues to grow, the need for effective recruitment and training of microsurgeons continues to be essential. Overall, we conclude that both the accessibility and quality of information available to applicants are limited, which is a missed opportunity for recruitment.Military physician Etienne Henrard has played an important role in both civil and military radiology. He was adjunct at the radiological department, created in 1897, in the military hospital in Brussels. In 1900, he equipped one of the first private cabinets in Brussels. He was especially interested in bone radiology, stereo-radiography and the localization of foreign bodies for which he invented, during the "Great War," a device for their extraction. In 1905, he was one of the founding members of the Belgian Radiological Society where he also held many functions. In 1931, he was promoted to the rank of Physician-General.
