Sural nerve injury after calcaneal sliding osteotomies is higher than previously reported in the scientific literature, with an incidence of 35.1% (20/57 patients). Respecting the so-called safe zone (oblique incision that runs through the point that is > 1/3 of the distance from the tip of the lateral malleolus to the posteroinferior margin of the calcaneus) clearly decreases the incidence of sural nerve injury. Finally, the majority of patients remained asymptomatic despite the neurological injury.

Three-dimensional (3-D) printed models are increasingly used to enhance understanding of complex anatomy in congenital heart disease.

To assess feasibility and accuracy of 3-D printed models obtained from cardiac CT scans in young children with complex congenital heart diseases.

We included children with conotruncal heart anomalies who were younger than 2years and had a cardiac CT scan in the course of their follow-up. We used cardiac CT scan datasets to generate 3-D models. To assess the models' accuracy, we compared four diameters for each child between the CT images and the printed models, including the largest diameters (D

) of ventricular septal defects and aortic annulus and their minimal diameters (D

).

We obtained images from 14 children with a mean age of 5.5months (range 1-24months) and a mean weight of 6.7kg (range 3.4-14.5kg). We generated 3-D models for all children. read more Mean measurement difference between CT images and 3-D models was 0.13mm for D

and 0.12mm for D

for ventricular septal defect diameters, and it was 0.16mm for D

and -0.13mm for D

for aortic annulus diameter, indicating a non-clinically significant difference.

Three-dimensional printed models could be feasibly generated from cardiac CT scans in a small pediatric population with complex congenital heart diseases. This technique is highly accurate and reliably reflects the same structural dimensions when compared to CT source images.

The informative value of computed tomography angiography (CTA) depends on the contrast phase in the vessels which may differ depending on the level of local expertise.

We retrospectively measured vessel contrast density from CTA scans in patients presenting with acute ischemic stroke to a comprehensive stroke center (CSC) or to one of eight primary stroke centers (PSC). CTAs were classified into arterial or venous phases as well as into 1 of 5 phases (early arterial, peak arterial, equilibrium, peak venous, and late venous).

Overall, n = 871 CTAs (CSC n = 431 (49.5%); PSC n = 440 (50.5%)) were included in the final analysis. A higher venous than arterial contrast density at the level of the circle of Willis was only rarely observed (overall n = 13 (1.5%); CSC n = 3/431 (0.7%); PCS n = 10/440 (2.3%); p = 0.09). CTAs acquired in the CSC showed more often an early arterial contrast phase (CSC n = 371 (86.1%); PSC n = 153 (34.8%), p < 0.01). Equilibrium contrast phase, i.e., a slightly stronger arterial is potential for further improvement of CTA acquisition protocols.

• Despite different technical equipment and examination protocols in the diagnostic workup of acute ischemic stroke, the total number of computed tomography angiography (CTA) with venous contrast was low (n = 13/871; 1.5%). • A higher venous than arterial contrast density at the level of the circle of Willis was not more frequent in CTAs from the centers with a high patient volume (comprehensive stroke center) compared to the hospital with lower patient volume (primary stroke centers). • Differences between the further differentiated contrast phases indicate that there is potential for further improvement of CTA acquisition protocols.

To compare the detection of relevant extracardiac findings (ECFs) on coronary computed tomography angiography (CTA) and invasive coronary angiography (ICA) and evaluate the potential clinical benefit of their detection.

This is the prespecified subanalysis of ECFs in patients presenting with a clinical indication for ICA based on atypical angina and suspected coronary artery disease (CAD) included in the prospective single-center randomized controlled Coronary Artery Disease Management (CAD-Man) study. ECFs requiring immediate therapy and/or further workup including additional imaging were defined as clinically relevant. We evaluated the scope of ECFs in 329 patients and analyzed the potential clinical benefit of their detection.

ECFs were detected in 107 of 329 patients (32.5%; CTA 101/167, 60.5%; ICA 6/162, 3.7%; p < .001). Fifty-nine patients had clinically relevant ECFs (17.9%; CTA 55/167, 32.9%; ICA 4/162, 2.5%; p < .001). In the CTA group, ECFs potentially explained atypical chest pain in 13cally relevant ECFs affect patient management and therapy and may thus improve chest pain. • Detection of ECFs explaining chest pain on CTA might preclude the need for performing ICA.

A stable and major QTL, which mapped to an approximately 20.0cM region on pea chromosome 4, was identified as the most consistent region conferring partial resistance to Aphanomyces euteiches. Aphanomyces root rot (ARR), caused by Aphanomyces euteiches Drechs., is a destructive soilborne disease of field pea (Pisum Sativum L.). No completely resistant pea germplasm is available, and current ARR management strategies rely on partial resistance and fungicidal seed treatments. In this study, an F

recombinant inbred line population of 135 individuals from the cross 'Reward' (susceptible) × '00-2067' (tolerant) was evaluated for reaction to ARR under greenhouse conditions with the A. euteiches isolate Ae-MDCR1 and over 2years in a field nursery in Morden, Manitoba. Root rot severity, foliar weight, plant vigor and height were used as estimates of tolerance to ARR. Genotyping was conducted with a 13.2K single-nucleotide polymorphism (SNP) array and 222 simple sequence repeat (SSR) markers. Statistical analyses of the phenotypic data indicated significant (P < 0.
