Zernike-like methods in polygons as well as polygonal aspects.
Recurrence-rate was 38% (N = 3).

This present study demonstrates that an acute HH after tMIE is a serious complication with an incidence of 2.6%. When symptomatic and acute, HH requires surgical intervention and has high postoperative morbidity and recurrence-rate. Therefore, this requires treatment in a centre specialised in oesophageal surgery.

To investigate differences between pituitary adenoma and craniopharyngioma on magnetic resonance imaging (MRI) with image features and three-dimensional texture features.

A total of 126 patients diagnosed with pituitary adenoma (N = 63) or craniopharyngioma (N = 63) were enrolled. HG6-64-1 Qualitative magnetic resonance (MR) image features and texture features of tumors were extracted from preoperative MRI and evaluated using chi-square test or Mann-Whitney U test. Binary logistic regression analyses were performed to assess their abilities as independent diagnostic predictors, and ROC analyses were conducted to evaluate the diagnostic value of significant features. Mann-Whitney U test and ROC analyses were performed to explore the relationship between MR image features and texture features.

Five MR image features were suggested to be significantly different between pituitary adenoma and craniopharyngioma. Three texture features from contrast-enhanced T1WI (HISTO-Skewness, GLCM-Contrast and GLCM-Energy), two texture features from T2WI (HISTO-Skewness and GLCM-Contrast) showed significant differences between two types of tumors. link2 Logistic regression analyses suggested GLCM-Energy from contrast-enhanced T1WI, HISTO-Skewness and GLCM-Contrast from T2WI could be taken as independent predictors. Moreover, HISTO-Skewness and GLCM-Contrast from T2WI were found to be significantly related to cystic change.

MR image features and texture features were associated with each other, and both types of features represented feasible diagnostic value in discrimination between pituitary adenoma and craniopharyngioma.

To compare the accuracy of non-electrocardiogram (ECG)-gated CT angiography (CTA), single-diastolic-phase ECG-gated CTA, and full-phase ECG-gated CTA in detecting the intimal tear (IT) in aortic dissection (AD) and ulcer-like projection (ULP) in intramural hematoma (IMH).

A total of 81 consecutive patients with AD and IMH of the thoracic aorta were included in this single-center retrospective study. Non-ECG-gated CTA, single-diastolic-phase ECG-gated CTA, and full-phase ECG-gated CTA were used to detect the presence of the IT and ULP in thoracic aortic regions including the ascending aorta, aortic arch, and proximal and distal descending aorta.

The accuracy of detecting the IT and ULP was significantly greater using full-phase ECG-gated CTA (88% [95% CI 100%, 75%]) than non-ECG-gated CTA (72% [95% CI 90%, 54%], P = 0.001) and single-diastolic-phase ECG-gated CTA (76% [95% CI 93%, 60%], P = 0.008).

Full-phase ECG-gated CTA is more accurate in detecting the IT in AD and ULP in IMH, than non-ECG-gated CTA and single-diastolic-phase ECG-gated CTA.

The objective of the current study was to assess the therapeutic benefit of lymphadenectomy according to the extent of lymphadenectomy.

Patients undergoing colectomy for right-sided colon cancer were identified. Distribution of lymph node metastases (DLNM) of 1, 2 and 3 were defined as lymph node metastasis (LNM) in the pericolic nodes, the intermediate nodes and the front of the SMV near the origin of the major artery, respectively. The therapeutic index (TI) was calculated based on the frequency of LNM and the 5year overall survival (OS) rate of patients with LNM.

Among 344 patients who met the inclusion criteria, roughly half had LNM (n = 150, 43.7%). While 107 (31.1%) and 30 (8.7%) patients had DLNM1 and DLNM2, respectively, only 13 patients (3.8%) were defined as DLNM3. link3 However, there was no significant difference in 5year OS by DLNM (DLNM1 71.1%, DLNM2 78.7%, DLNM3 50.4%, p = 0.61). Overall, the TI of lymphadenectomy for D3 area was approximately 1/10 of the TI for D1 (1.9 vs.22.1), given the low frequency of LNM (3.8%) and poor 5year OS of patients with LNM (50.4%). This trend was consistent irrespective of primary tumor locations.

The survival benefit from central lymphadenectomy namely D3 was low among patients with right-sided colon cancers.

In recent years, many medical specialties with avisual focus have been revolutionized by image analysis algorithms using artificial intelligence (AI). As dermatology belongs to this field, it has the potential to play apioneering role in the use of AI.

The current use of AI for the diagnosis and follow-up of dermatoses is reviewed and the future potential of these technologies is discussed.

This article is based on aselective review of the literature using Embase and MEDLINE and the keywords "psoriasis", "eczema", "dermatoses" and "acne" combined with "artificial intelligence", "machine learning", "deep learning", "neural network", "computer-guided", "supervised machine learning" or "unsupervised machine learning" were searched.

In comparison to examiner-dependent intra- and interindividually fluctuating scores for the assessment of inflammatory dermatoses (e.g. the Psoriasis Areas Severity Index [PASI] and body surface area [BSA]), AI-based algorithms can potentially offer reproducible, standardized evaluations of these scores. Whereas promising algorithms have already been developed for the diagnosis of psoriasis, there is currently only scarce work on the use of AI in the context of eczema.

The latest developments in this field show the enormous potential of AI-based diagnostics and follow-up of dermatological clinical pictures by means of an autonomous computer-based image analysis. These noninvasive, optical examination methods provide valuable additional information, but dermatological interaction remains indispensable in daily clinical practice.

To date, clinical data on real-world treatment practices in Japanese patients with atrial fibrillation (AF) after bioprosthetic valve (BPV) replacement are needed. We conducted a large-scale, prospective, multicenter study to understand the actual usage of antithrombotic therapy and the incidence of thromboembolic and bleeding events in these patients, and to eliminate the clinical data gap between Japan and Western countries.

This was an observational study, in patients who had undergone BPV replacement and had a confirmed diagnosis of AF, with no mandated interventions. We report the baseline demographic and clinical data for the 899 evaluable patients at the end of the enrollment period.

Overall, 45.7% of patients were male; the mean age was 80.3years; AF was paroxysmal, persistent, or permanent in 36.9%, 34.6%, and 28.5% of patients, respectively. Mean risk scores for stroke and bleeding were 2.5 (CHADS
), 4.1 (CHA
DS
-VASc), and 2.5 (HAS-BLED). Many patients (76.2%) had comorbid hypertension and 54.8% had heart failure. Most BPVs (65.5%) were positioned in the aortic valve. Warfarin-based therapy, direct oral anticoagulant (DOAC)-based therapy, and antiplatelet therapy (without warfarin and DOAC) were administered to 55.0%, 29.3%, and 9.7% of patients, respectively.

Patients enrolled into this study are typical of the wider Japanese AF/BPV population in terms of age and clinical history. Future data accruing from the observational period will contribute to future treatment recommendations and guide therapeutic decisions in patients with BPV and AF.

We report a case of a patient without portal hypertension, but with bleeding gastric varices with a presumed splenorenal shunt (SRS) on CT. Venography revealed flow reversal through the shunt (directed from the renal vein, into the splenic vein and out the portal vein; a renal-splent shunt (RSR)) and thus an anatomically similar but functionally distinct systemic to mesenteric variant. While being anatomically similar to the well-known SRS, the different flow dynamics necessitate a different approach for treatment and important considerations for the use of any liquid embolic.
The optimal management of valgus-impacted femoral neck fractures remains controversial. Internal fixation is associated with significant rates of re-operation, while historical non-operative management strategies consisting of prolonged bed rest also resulted in patient morbidity. Our hypothesis was that screw fixation would have comparable failure rates to non-operative treatment and immediate mobilization for valgus-impacted femoral neck fractures.

Retrospective cohort at a single academic Level I trauma center of patients with valgus-impacted femoral neck fractures (AO/OTA 31-B1) treated with percutaneous screw fixation (n = 97) or non-operatively (n = 28). Operative treatment consisted of percutaneous screw fixation. Non-operative treatment consisted of early mobilization. The primary outcome was a salvage operation. Patient demographics were assessed between groups.

More non-operatively treated patients were permitted unrestricted weight-bearing (WBAT; p = 0.002). There was no increase in complicat controlling for weight-bearing restrictions, we found no difference in failure rates between non-operative treatment and screw fixation. Non-operative treatment with partial weight-bearing had low failure rates, comparable complication and mortality rates, and equivalent functional outcomes to operative treatment and is reasonable if a patient would like to avoid surgery and accepts the risk of subsequent arthroplasty. Overall, there were relatively high failure rates in all groups.
The ACS-NSQIP surgical risk calculator (SRC) is an open-access online tool that estimates the chance for adverse postoperative outcomes. The risk is estimated based on 21 patient-related variables and customized for specific surgical procedures. The purpose of this monocentric retrospective study is to validate its predictive value in an Italian emergency setting.

From January to December 2018, 317 patients underwent surgical procedures for acute cholecystitis (n = 103), appendicitis (n = 83), gastrointestinal perforation (n = 45), and intestinal obstruction (n = 86). Patients' personal risk was obtained and divided by the average risk to calculate a personal risk ratio (RR). Areas under the ROC curves (AUC) and Brier score were measured to assess both the discrimination and calibration of the predictive model.

The AUC was 0.772 (95%CI 0.722-0.817, p < 0.0001; Brier 0.161) for serious complications, 0.887 (95%CI 0.847-0.919, p < 0.0001; Brier 0.072) for death, and 0.887 (95%CI 0.847-0.919, p < 0.
