Purpose The purpose of this study was to compare the clinical outcomes from using eye bank-prepared, endothelium-out preloaded Descemet membrane endothelial keratoplasty (DMEK) tissue with those obtained with endothelium-out surgeon-loaded DMEK tissue using the same surgical technique at 1 site. Methods This study retrospectively reviewed 400 consecutive cases of DMEK from March 2016 to April 2018. The last 200 cases using surgeon-loaded tissue were compared with the first 200 cases using preloaded tissue. Statistical analysis was performed using the Wilcoxon signed-rank test, binomial logistic regression, Kruskal-Wallis 1-way analysis of variance, Student t test, or Pearson χ tests. Results Comparing surgeon-loaded versus preloaded DMEK tissue, respectively, no statistical difference was found in the mean 6-month postoperative values for endothelial cell loss (32.9% ± 18.5% vs. 29.9% ± 16.4%, P = 0.31), best corrected visual acuity (20/26 vs. 20/25, P = 0.54), or change in central corneal thickness (-14.4% ± 8.9% vs. -15.6% ± 11.7%, P = 0.43). The mean 1-year endothelial cell loss was also not significantly different (37.6% ± 17.2% vs. 33.2% ± 14.8%, P = 0.07). Overall, the rebubble rate for surgeon-loaded tissue was 17.5% and 12.5% for preloaded tissue, a statistically nonsignificant difference. Operative outcomes for mean tissue scroll tightness (1-4) and tissue unscroll time (minutes) for surgeon-loaded and preloaded tissue were similar between groups (2.4 vs. 2.2, P = 0.12 and 3.5 vs. 3.3 minutes, P = 0.50). Conclusions Tissue that is trephinated, stained, and loaded into an injector by the eye bank and then shipped to the surgeon had no difference in clinical outcomes compared with tissue where the surgeon performs these steps. The safety and speed of using preloaded tissue should be considered by DMEK surgeons.Purpose To evaluate the outcomes of Descemet membrane endothelial keratoplasty (DMEK) in aphakic and aniridic eyes. Methods A retrospective chart review of either aphakic or aniridic patients who underwent DMEK at Toronto Western Hospital, Canada, between 2015 and 2019 was performed. Demographic characteristics, intraoperative and postoperative complications, and best corrected visual acuity (BCVA) were analyzed. Results Nine eyes of 9 patients, aged 51.0 ± 8.6 years, were included (3 aniridic, 5 aphakic, and 1 combined). The average follow-up was 15.7 ± 12.7 months. The best corrected visual acuities before surgery and 3 and 6 months after surgery were 1.28 ± 0.47, 1.33 ± 0.98, and 1.03 ± 0.56 LogMAR, respectively. Six eyes (67%) had graft detachment, with 3 of them larger than 30% of the graft area. One eye (11%) developed hyphema. The overall failure rate was 88% (8 of 9 eyes), meaning only one was viable at the last follow-up. Primary graft failure was seen in 4 eyes (44%) after detachment (n = 3) and intraoperative hyphema (n = 1). Secondary failure occurred in 4 eyes (44%) at 7, 12, 15, and 36 months. The secondary failure at 36 months was after rejection. Failures were managed with penetrating keratoplasty (n = 2), repeat DMEK (n = 3), Descemet stripping automated endothelial keratoplasty (n = 1), and observation because of poor vision potential (n = 2). Cumulative graft survival probabilities at 12 and 24 months were 44% and 17%, respectively. Conclusions Aniridic and aphakic patients experienced unacceptably high detachment and failure rates after DMEK. Before performing DMEK, the risks and benefits should be carefully weighed and perhaps other keratoplasty techniques should be used.Face-sensitive N170 component of event-related potential is sensitive to face inversion, which has been defined as the face-inversion effect. Moreover, a previous study suggested that similar to the face-inversion effect of the face-sensitive N170 affected by mental rotation of the face, object-related N170 of three-dimensional objects was also affected by the mental rotation of two-dimensional objects. The purpose of the present study was to compare the relationship between face-sensitive N170 during face perception (upright and inverted faces) and object-related N170 during character perception (normal and mirror version for alphabet characters). The results indicated that the latency of N170 for mirror version for alphabet characters was significantly longer than that for normal version for alphabet characters, and the latency of N170 for inverted faces was significantly longer than that for upright faces. Therefore, the results of the present study clearly indicate that face-sensitive N170 components are related to the mental rotation of normal and mirror version for alphabet characters. These results suggest the novel possibility that face-sensitive N170 latency can be used as a biomarker for mental rotation and that mental rotation is related to the fusiform area as a neural generator of N170 in the human brain.White solids were observed in the esophagus of a patient with multiple system atrophy. The patient was receiving enteral nutrition with a polymeric formula and cranberry juice via nasogastric feeding. To test the assumption that the precipitates were formed from a reaction between the juice and the formula, a verification experiment was conducted usingformulae of differinging redients, pH and protein content. The results indicated that a precipitate was formed when formulae with lower pH values and higher protein content were used. Mixing a pH neutral enteral formula with cranberry juice, vinegar or their 2- fold diluted solutions may result in the formation of precipitates in the stomach and esophagus.An 89-year-old woman with recurrent hormone receptor-positive and HER2-negative breast cancer was treated with fulvestrant-palbociclib combination therapy. However, 3 months after therapy initiation, she presented to our emergency room with dyspnea and fever and was admitted to our hospital because of respiratory failure. mTOR activation After radiological and microbiological evaluation, she was diagnosed with palbociclib-related pneumonitis. Accordingly, corticosteroids were administered, and the patient exhibited initial clinical and radiological improvement. However, pneumonitis recurred following corticosteroid tapering; her condition did not improve with high-dose intravenous corticosteroid administration, leading to death. Palbociclib- related pneumonitis is rare, but clinicians need to pay attention to this potentially lethal adverse event.
