State of the art regeneration of the tympanic membrane.

Purpose Of Review: One of the most common diseases of the tympanic membrane is a perforation, and tympanoplasty is one of the more common procedures in otolaryngology. Tympanic membrane regeneration and bioengineering aim to improve the success rate of the procedure, increase the availability of different scaffolds and provide innovative tools that will simplify the surgical technique and make it accessible for surgeons with varying expertise level. This review aims to raise awareness of current tissue engineering developments in tympanic membrane regeneration and how they may augment current clinical practices.

Closed-suction compared with Penrose drainage after free flap reconstruction in the head and neck.

Microsurgical free flaps are common in head and neck reconstruction, and their techniques and outcomes have continuously improved during the past decades. However, there are variations in practice among surgeons between the use of closed-suction drainage systems and Penrose drains. The proponents of Penrose drains propose that the negative pressure generated by the closed-suction drainage system may harm the microvascular anastomosis.

The significance of Computed Tomography in invasive paranasal mucormycosis.

Introduction: Early diagnosis of acute invasive fungal rhinosinusitis (AIFR) is crucial for patients prognosis and may reduce the extent of surgical debridement. Initial evaluation usually includes paranasal Computed Tomography (CT), with an emphasis on bony erosion which is considered a specific but insensitive radiologic sign. Most studies made no distinction between Aspergillus and Mucor species while addressing CT findings.

Mutations in AIFM1 cause an X-linked childhood cerebellar ataxia partially responsive to riboflavin.

Background: AIFM1 encodes a mitochondrial flavoprotein with a dual role (NADH oxidoreductase and regulator of apoptosis), which uses riboflavin as a cofactor. Mutations in the X-linked AIFM1 were reported in relation to two main phenotypes: a severe infantile mitochondrial encephalomyopathy and an early-onset axonal sensorimotor neuropathy with hearing loss. In this paper we report two unrelated males harboring AIFM1 mutations (one of which is novel) who display distinct phenotypes including progressive ataxia which partially improved with riboflavin treatment.
