Assessment of the Audiological Profile and Related Risk Factors for Sensorineural Hearing Loss in Children with Speech and Language Delay.

Hearing is crucial for the development of language skills. Many infants and young children with undiagnosed hearing impairments, particularly those with mild to moderate severity and no apparent risk factors, miss out on much of the critical early phase of language and speech development. This cross-sectional, hospital-based observational study was conducted at GSVM Medical College and LLRH Hospital on children aged 6 months to 5 years over a 12-month period.

Activity measurements and calibrations for Ac in radioactive equilibrium with its progeny.

The massic activity of Ac in 0.1 mol/L HCl was measured by multiple primary methods over four consistent measurement campaigns. Results from the triple-to-double coincidence ratio (TDCR) method of liquid scintillation (LS) counting were in accord with other LS-based primary methods.

Therapeutic Misadventure in a Case of Isolated Mastoid Cholesteatoma.

Cholesteatoma is a mass of keratin debris in the middle ear cavity or mastoid. Congenital cholesteatomas may remain asymptomatic for many years and present during adulthood or may even be an incidental finding. We hereby describe a case of 41-year male with an isolated mastoid congenital cholesteatoma with sigmoid plate erosion and posterior cranial dura exposure extending into digastric muscle.
