there are gaps in medical education. Only 13.3% were confident about NT, and their knowledge did not justify such confidence. There were no differences between the successes of confident and non-confident about NT in most subjects. The best results came from the group that claimed to be assisted by any NTMT. Better medical educational programs should be goal for this university.

Background To evaluate the reliability of foveal avascular zone (FAZ) area measurements using optical coherence tomography angiography (OCTA) in eyes with retinal vein occlusion (RVO). Methods Twenty-five OCTA exams of patients with RVO were evaluated retrospectively. Three examiners performed manual measurements of the FAZ, and interrater and intrarater reliability were obtained. Results The intraclass correlation coefficient (ICC) for interrater reliability for individual measurements was 0.62 (moderate) with a 95% confidence interval (CI) of 0.40 to 0.79 (p < 0.001). The ICC (95% CI) for intrarater reliability was 0.92 (0.82 to 0.96) for rater A, 0.96 (0.91 to 0.98) for B, and 0.88 (0.76 to 0.94) for C (p < 0.001). In all subanalyses including presence of edema and type of occlusion, interrater reliability was poor/moderate, and intrarater reliability was good/excellent. Conclusion The FAZ varies significantly among eyes with RVO, so measurements obtained using OCTA should be analyzed with caution due to the moderate level of reliability among different examiners.

This is a case of Purtscher-like retinopathy associated with paracentral acute middle maculopathy caused by industrial silicone embolism after an illicit cosmetic procedure for buttock augmentation. Color fundus photography and optical coherence tomography were able to determine the characteristics features of Purtscher-like retinopathy and paracentral acute middle maculopathy.

Motor impairment following stroke is a leading cause of disability in adults. Despite advances in motor rehabilitation techniques, many adult stroke survivors never approach full functional recovery. Intriguingly, children exhibit better rehabilitation outcomes when compared to adults suffering from comparable brain injuries, yet the reasons for this remain unclear. A common explanation is that neuroplasticity in adults is substantially limited following stroke, thus constraining the brain's ability to reorganize in response to neurological insult. This explanation, however, does not suffice for there is much evidence suggesting that neuroplasticity in adults is not limited following stroke. We hypothesize that diminished functional recovery in adults is in part due to inhibitory neuronal interactions, such as transcallosal inhibition, that serve to optimize motor performance as the brain matures. Following stroke, these inhibitory interactions pose rigid barriers to recovery by inhibiting activity in the affected regions and hindering recruitment of compensatory pathways. In contrast, children exhibit better rehabilitation outcomes in part because they have not fully developed the inhibitory interactions that impede functional recovery in adults. We suggest that noninvasive brain stimulation can be used in the context of motor rehabilitation following stroke to reduce the effects of existing inhibitory connections, effectively returning the brain to a state that is more amenable to rehabilitation. We conclude by discussing further research to explore this hypothesis and its implications.
