To our knowledge, we report the first case of corneal perforation in which evisceration was required following treatment with topical lifitegrast for chronic GVH. In the case presented here, it can be assumed that the underlying mechanisms leading to corneal perforation are multifactorial. Using drug accountability criteria, lifitegrast appears to be strongly associated with the development of bacterial keratitis and corneal perforation.
To potentially limit peri-implant fractures our institution commonly implements a "stress-taper" fixation construct in which the screw lengths towards the proximal end of a construct are incrementally decreased, in order to avoid a focal stress-riser when loaded. To assess this construct, we asked 1) Does the stress taper strategy increase torsional strength than the bicortical locking construct when biomechanically tested in a cadaveric femur model? 2) Does it fail in a less comminuted fracture pattern?

Seven matched pairs of cadaveric femora were randomly assigned to one of two distal femur fixation groups plating with stress taper strategy or bicortical fixation. Specimens were first cyclically loaded, then axially rotated to failure under 800N of compression. Peak torque at failure, degrees of rotation at failure, and energy to failure were calculated and compared using paired t-tests. Fractures were categorized with the assistance of fluoroscopy according to the Orthopedic Trauma Association classification, 32.

There was significantly greater peak torque (110.6±49.7Nm vs. 80.6±35.2Nm), rotation at failure (23.8±5.3° vs 18.9±4.5°) and energy to failure (25.3±15.7J vs. 14.1±8.3J) in the stress-taper group as compared to the bicortical group (p=0.0424), (p=0.0213) and (p=0.0460), respectively. 6/7 fractures in the stress-taper group were classified 32 A1 with 1/7 classified A2. 5/7 fractures in the bicortical group were classified B1 and 2/7 classified A2.

'Stress taper fixation' in distal femurs may be protective against peri-implant fractures compared to traditional bicortical fixation. The 'stress taper' concept can increase torsional failure strength in an in vitro model.

To evaluate the association between perihaematomal radiomics features and haematoma expansion (HE).

Clinical and radiological data were collected retrospectively. The 11 propensity score matching (PSM) method was used to balance the difference of baseline characteristics between patients with and without HE. Radiomics features were extracted from the intra- and perihaematomal regions. Top HE-associated features were selected using the minimum redundancy, maximum relevancy algorithm. Support vector machine models were used to predict HE. GSK1070916 price Predictive performance of radiomics features from different regions was evaluated by receiver operating characteristic curve and confusion matrix-derived metrics.

A total of 1,062 patients were enrolled. After PSM analysis, the propensity score-matched cohort (PSM cohort) included 314 patients (HE n=157; non-HE n=157). The PSM cohort was distributed into the training (n=218) and the validation cohorts (n=96). The predictive performance of intra- and perihaematomal features were comparable in the training (area under the receiver operating characteristic curve [AUC], 0.751 versus 0.757; p=0.867) and the validation cohorts (AUC, 0.724 versus 0.671; p=0.454). By incorporating intra- and perihaematomal features, the combined model outperformed the single intrahaematomal model in the training cohort (AUC, 0.872 versus 0.751; p<0.001). Decision curve analysis (DCA) further confirmed the clinical usefulness of the combined model.

Perihaematomal radiomics features can predict HE. The integration of intra- and perihaematomal signatures may provide additional benefit to the prediction of HE.

There is no consensus on the treatment of drug reaction with eosinophilia and systemic symptoms (DRESS). At our center, systemic steroids (SS) are used for severe cases while topical steroids (TS) are used for mild and moderate forms.

To investigate the short-term outcome for patients with DRESS receiving SS as first-line therapy before being transferred to our department and then switched to TS after admission.

A retrospective monocenter study in DRESS patients (RegiSCAR score≥4) transferred to our dermatology department from a different setting between 07/2012 and 06/2018 and who had received SS before being transferred. Epidemiological, clinical and laboratory data were collected, as well as details of treatment modalities and outcome.

Twenty patients were included. On admission to our department, 4 were assessed as having severe DRESS and continued on SS, while 16 were assessed as mild/moderate DRESS and were switched to TS. Among these 16 patients, the outcome on TS was favorable for 12 and quickly unfavorable for 4, who had to be switched back to SS. Retrospective analysis of the initial data (before transfer) showed that these 4 patients had previously had a greater number of severity criteria than the other 12.

Caution is needed not only when deciding to initiate SS in DRESS but also on withdrawal of these drugs. Our series suggests that when SS are used as first-line therapy in DRESS patients with initial severity criteria, they should not be withdrawn quickly for a switch to TS, even where progression appears favorable, due to the risk of relapse.

Cardiac AP waveforms are shaped by a striking diversity of K+ channels. The pivotal role of K+ channels in cardiac health and disease is underscored by the dramatic impact that K+ channel dysfunction has on cardiac arrhythmias. The development of drugs targeted to specific K+ channels is expected to provide an optimized approach to antiarrhythmic therapy. Here, we review the functional roles of cardiac potassium channels under normal and diseased states. We survey current antiarrhythmic drugs (AADs) targeted to voltage-gated and Ca2+-activated K+ channels and highlight future research opportunities.
