We report meconium aspiration in 2 sibling goat kids, and characterize the expected lesions of aspiration pneumonia in conjunction with the rare lesion of otitis media. Grossly, the lungs were multifocally consolidated, and there was yellow-green exudate within the middle ear. Histologically, the lung was characterized by pyogranulomatous pneumonia and foreign-body reaction around aspirated debris. Within the lumen of the middle ear, aspirated squamous cells, keratin, meconium debris, and neutrophils, without evidence of bacteria, were accompanied by a subepithelial accumulation of lymphocytes, plasma cells, and fewer macrophages. This is an especially rare phenomenon, which is thought to result from transport of meconium from the oropharynx through the auditory tube (Eustachian tube) to the middle ear.

Background: In some rare cases of congenital aplasia of the oval window (OW), malformed facial nerve (FN) locations covering the most or entire OW present a challenge to hearing reconstruction, there is no a highly effective surgical hearing reconstruction methods.
Aims/objectives: To update a Scala tympani drill-out technique (SDT) for abnormal FN course covering the OW.
Material And Methods: All patients of congenital atresia of the OW was recruited between August 2014 and July 2023 in a tertiary-care center.

With recent technical advances, many cognitive and sensory tasks have been adapted for smartphone testing. This study aimed to assess the criterion validity of a subset of self-administered, open-source app-based cognitive and sensory tasks by comparing test performance to lab-based alternatives. An in-person baseline was completed by 43 participants (aged 21 to 82) from the larger Labs without Walls project (Brady et al.
