31), and PT (P = 0.011, r = 0.39). There has been statistically significant moderate positive correlations of splenic stiffness values with PT (P = 0.047, r = 0.34), and INR (P = 0.038, r = 0.35). The sensitivity and specificity of liver stiffness cutoff value as 11.1 kPa for detection of Fontan associated liver disease were 95% and 100%, respectively. The hepatic and splenic stiffness increase independently in Fontan patients due to parenchymal disease. Hepatic SWE is a reliable and noninvasive predictor of early hepatic alterations that could not be detected only by biochemical results or routine ultrasound examinations.The aim of our study is to compare 2 prostate fusion biopsy models in terms of accurate target sampling. One hundred patients who had Prostate Imaging-Reporting and Data System score 3, 4, or 5 lesions (lesion diameter, >5 mm in long axis) in multiparametric-magnetic resonance imaging and prostate-specific antigen levels between 3 and 10 ng/mL were enrolled in the study. All patients were biopsy naive. Two groups were composed with 50 patients each. Group 1 patients had cognitive fusion (CF) biopsy, and group 2 had magnetic resonance-ultrasound fusion platform biopsy. After fusion biopsy, standard biopsy was also performed. Outcomes of histopathologic and demographic data were evaluated statistically. There were no statistical differences between the 2 groups in terms of age, prostate-specific antigen levels, prostate volume, and lesion length (P > 0.05). There was no statistically significant difference in sampling targeted lesions (P > 0.05). Also, no difference was found between the 2 groups in terms of random biopsy cancer detection rates (P > 0.05). There was no statistically significant difference between CF and magnetic resonance-ultrasound fusion in terms of cancer detection rates. For the experienced operators, we recommend lesions that are longer than 5 mm can be sampled using CF, an inexpensive and faster technique.This article reviews the ultrasound (US) scanner setting, the examination methodology, and the anatomy of the skin. Dermatologic US requires frequencies of 15 MHz or greater and appropriate probe handling. The use of color Doppler imaging is mandatory, proven that it is set to detect slow flows. Trapezoid field of view, extended field of view, 3-dimensional reconstruction, elastography, and new microvasculature imaging facilities can help, if available. Operators must be aware of the adjustments and tricks useful to improve the image quality. High-resolution US allows detailed assessment of epidermis, dermis, subcutaneous tissue, and skin appendages. Differences exist according to patient age, sex, and body area. Appropriate knowledge of the anatomy is mandatory to image skin abnormalities.Ultrasound (US) is replete with pitfalls in technique and interpretation, and renal imaging is no exception. Because US of the kidneys is a very common initial and follow-up imaging examination, it is important to be aware of both common and unusual sources of potential error. This essay will review optimal technique and discuss common overcalls, under calls, and misinterpretations with respect to renal size, hydronephrosis, calculi, cysts, masses, and collections.

First-line regimens in the treatment of metastatic colorectal cancer (mCRC) combine a fluoropyrimidine with oxaliplatin (FOLFOX/XELOX) or irinotecan (FOLFIRI). There is limited efficacy data to guide the selection of one treatment over the other. This study investigated whether mutations affecting DNA damage response (DDR) could differentially influence the response to oxaliplatin and irinotecan-containing regimens.

We retrospectively analyzed 49 patients with mCRC for whom treatment outcomes and results of comprehensive genomic profiling of tumors were available. Specimens with at least 1 pathogenic mutation involving BRCA1, BRCA2, ATM, BARD1, BRIP1, CDK12, CHEK1, CHEK2, FANCL, PALB2, PPP2R2A, RAD51B, RAD51C, RAD51D, or RAD54L were classified as DDR-mutated, while those without mutations were DDR-wild-type (WT). click here We compared the overall survival (OS), disease control rate, and response rate (RR) between the DDR-mutated and DDR-WT groups.

DDR mutations occurred in 11 patients (22%). First-line treatment with an oxaliplatin-containing regimen was administered to 33 patients (31 FOLFOX, 2 XELOX), while 16 patients received FOLFIRI. Among DDR-mutated cases, first-line treatment with FOLFOX/XELOX correlated with a statistically significant improvement in median OS compared with FOLFIRI (3.4 vs.1.8 y; P=0.042) and numerically higher RR (50% vs. 33%; P=0.58). No significant difference in OS (2.4 vs. 2.5 y; P=0.42), RR, disease control rate was observed between the 2 regimens in patients with DDR-WT tumors.

Mutations in DDR genes were present in 22% of patients with mCRC. In patients with DDR-mutated tumors, initial treatment with FOLFOX/XELOX correlated with improved OS and a numerically higher RR compared with FOLFIRI.

High-grade spondylolisthesis (HGS) (Myerding grade III-V) in adolescents can lead to a marked alteration of gait pattern and maybe the presenting symptom in these patients. This characteristic gait pattern in patients with HGS has been referred to as the “pelvic waddle.” Modern 3-dimensional (3D) gait analysis serves an important tool to objectively analyze the different components of this characteristic gait preoperatively and postoperatively and is an objective measure of postoperative improvement.This study demonstrates the use of 3D gait analysis preoperatively and postoperatively in a cohort of 4 consecutive patients with HGS treated surgically at a single tertiary referral center and utilize this to objectively evaluate outcome of surgical treatment in these patients. This has not been reported previously in a cohort of patients.

This is a prospective analysis of patients with HGS who underwent surgical intervention for spondylolisthesis at a single institution. Patient demographics, clinical, and radiologic assessment were recorded, and all patients underwent 3D gait analysis before and after surgical intervention.
