Severe Nerve Enlargement in SOS2‐Related Noonan Syndrome
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Noonan syndrome is a genetic multisystem congenital disorder, caused by pathogenic variants in genes that encode components of the RAS/MAPK signaling pathway. Pathogenic variants in SOS2 represent less than 2% of cases with NS. The phenotype includes a particularly high prevalence (65%) of lymphatic disease. Recently, severe nerve enlargements

The Anatomical Record, EarlyView.Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Diagnostic Cytopathology, EarlyView.ABSTRACT Fine needle aspiration (FNA) is widely accepted as an efficient first‐line diagnostic tool for evaluating salivary gland lesions. It can accurately diagnose a majority of common benign tumors, including pleomorphic adenoma (PA). However, PA can exhibit a wide range of morphological variations, which may lead to misinterpretation.

Ipsilateral cochlear implantation in cases with vestibular schwannoma
Eye &ENT Research, EarlyView.Abstract Background Vestibular schwannomas (VS) are the most common tumors in the cerebellopontine angle, which can lead to hearing loss, particularly following tumor resection. For patients with bilateral VS associated with neurofibromatosis type 2 (NF2), hearing loss significantly undermines their quality of life.
