Objective: To study the anatomy and preparation methods of an improved lateral arm free flap (LAFF) for the future clinical application.
Methods: Twenty-two adult upper extremities from cadavers after injected with red latex through common carotid arteries were used. The course, branches, distribution and variations of the blood vessels and nerves of the improved LAFF were observed. The outer diameters of the vessels were measured.
Results: The mean length of vascular pedicle of the improved LAFF was (14.85 ± 1.28) cm, significantly more than that (5.46 ± 2.60) of traditional LAFF (t = -8.483, P < 0.001). The mean outer diameters of pedicle arteries and veins in the improved LAFF were (2.24 ± 0.66) mm and (2.22 ± 0.52) mm, significantly more than those (1.15 ± 0.21 and 1.26 ± 0.23) in traditional LAFF (t = -8.690, P < 0.001; t = -15.057, P < 0.001), respectively.
Conclusion: The improved LAFF has a longer vascular pedicle and larger artery and vein in diameter than conventional LAFF, and is more suitable for the repair of the small and medium-sized defects of the head and neck.

The segmentation of blurred cell boundaries in cornea endothelium microscope images is challenging, which affects the clinical parameter estimation accuracy. Existing deep learning methods only consider pixel-wise classification accuracy and lack of utilization of cell structure knowledge. Therefore, the segmentation of the blurred cell boundary is discontinuous.

Purpose Despite the recognition that family-centered services are best practice in augmentative and alternative communication services, many speech-language pathologists (SLPs) are lacking in their acquisition and implementation of family-centered skills. The purpose of this study was to evaluate the effects of online instruction in a family-centered, relational skills strategy on preservice SLPs use of family-centered skills. Method A switching replications design was used to evaluate the effects of an online training on the use of family-centered behaviors by 15 preservice SLPs who were randomly assigned to two groups.

Background: Compared with graduate students and young adults in the general population, depression is more prevalent among training physicians, yet physicians are often reluctant to seek mental health treatment. The purpose of this study is to identify perceived barriers to mental health treatment among depressed training physicians.
Methods: Subjects for this study were drawn from intern classes during the 2007-2008 and 2008-2009 academic years from 6 and 13 participating community and university hospitals, respectively.

A 23-year-old right-handed woman developed isolated transient prosopagnosia following surgical resection of a right posterior temporal seizure focus. At 18 years of age she had developed secondarily generalized tonic-clonic seizures. Preoperative neuropsychological evaluation was normal, and neurological examination revealed only a left superior quadrant achromatopsia.
