Ingestion of 14 Hearing Aid Batteries in an Adult Patient.

Battery ingestion is not a common occurrence in adults. When it occurs in patients of any age, prompt action might be necessary, depending on the type of battery ingested, to prevent damage to the gastric mucosa that is involved in important secreting and absorbing functions required to maintain homeostasis. A 61-year-old Hispanic male presented to the emergency department with the chief concern of shortness of breath and abdominal pain.

Developmental loss of neurofibromin across distributed neuronal circuits drives excessive grooming in Drosophila.

Neurofibromatosis type 1 is a monogenetic disorder that predisposes individuals to tumor formation and cognitive and behavioral symptoms. The neuronal circuitry and developmental events underlying these neurological symptoms are unknown. To better understand how mutations of the underlying gene (NF1) drive behavioral alterations, we have examined grooming in the Drosophila neurofibromatosis 1 model.
