Necrotizing enterocolitis (NEC) is the most common gastrointestinal disease of premature infants. However, despite significant morbidity and mortality, the etiology and pathogenesis of NEC are poorly understood. Evidence suggests that ileal proinflammatory mediators such as IL-18 contribute to the pathology associated with this disease. In addition, we have(More)
Dilated fundoscopic exam is considered the gold standard for detecting retinal hemorrhage, but expertise in obtaining this exam is not always immediately available. MRI can detect retinal hemorrhages, but correlation of the grade or severity of retinal hemorrhage on dilated fundoscopic exam with retinal hemorrhage visibility on MRI has not been described.(More)
Intraocular medulloepithelioma (IO MEPL) is an uncommon embryonal neuroepithelial neoplasm of the eye. These ocular neoplasms have been compared with intracranial medulloepitheliomas or other histologic variants of CNS embryonal tumor with multilayered rosettes (CNS ETMR) due to their morphological mimicry. We performed comprehensive molecular analysis to(More)
A 12-month-old male infant, noted from birth to have a diffuse right temporal epibulbar thickening that encroached on the limbus inferotemporally, was found to manifest stigmata of Goldenhar syndrome, including a limbal dermoid with vellus hairs, esotropia, astigmatism, fullness and ectropion of the lower eyelid, preauricular skin tag, agenesis of the right(More)
PURPOSE To compare immunohistochemical and genetic overlaps and differences between intraocular medulloepitheliomas and embryonal tumors with multilayered rosettes of the brain. DESIGN Retrospective histopathologic, immunohistochemical, and genetic analysis of 20 intraocular medulloepitheliomas. METHODS (1) Review of clinical data and(More)
PURPOSE To describe the fabrication, evaluation, and preliminary in vivo safety of a new drug delivery system (DDS) for topical anti-TNF-α antibody administration. METHODS A DDS was fabricated using inverse template fabrication of a hydrophobic three-dimensional porous scaffold (100-300 μm in diameter porosity) loaded with 10% polyvinyl alcohol hydrogel(More)
PURPOSE To determine the incidences, clinical features, and detailed histopathologic and immunohistochemical findings of 10 peripheral nerve tumors (isolated neurofibromas, solitary circumscribed neuromas [SCNs], and schwannomas) localized to the eyelid dermis. METHODS In this retrospective clinicopathologic study, clinical records and paraffin sections(More)
A 63-year-old man presented with an asymptomatic papillary, sessile lesion of the juxtalimbal bulbar conjunctiva that was surgically excised with cryotherapy. Histopathologically, the lesion created some diagnostic confusion as it displayed an endophytic, or inverted, growth pattern-with squamous cells pushing into the substantia propria around(More)
A 79-year-old man underwent excision of an upper eyelid mass that had been enlarging for 3 months. Histopathologic evaluation demonstrated a cyst lined by pseudostratified columnar epithelium with myriad goblet cells and cilia, and immunostaining revealed cytokeratins indicative of a respiratory origin. This rare condition, the first described exclusively(More)
