The Use of a Fabricated Endotracheal Tube During an Acute Massive Pulmonary Hemorrhage: A Case Report.

A massive pulmonary hemorrhage is an emergency that can lead to airway compromise and cardiovascular collapse. The goals of airway management are to isolate and protect the nonbleeding lung while providing a route for interventions to diagnose and control the bleeding site. We present a case of an adult male with a lung mass who underwent a bronchoscopy and cryobiopsy that was complicated by a massive pulmonary hemorrhage.

Peripheral neuromodulation for the treatment of refractory trigeminal neuralgia.

Trigeminal neuralgia is a type of orofacial pain that is diagnosed in 150,000 individuals each year, with an incidence of 12.6 per 100,000 person-years and a prevalence of 155 cases per 1,000,000 in the United States. Trigeminal neuralgia pain is characterized by sudden, severe, brief, stabbing or lancinating, recurrent episodes of pain in the distribution of one or more branches of the trigeminal nerve, which can cause significant suffering for the affected patient population.

Basic flap design.

Basic flap design utilization for reconstruction of head and neck defects requires creativity from the surgeon. Ultimately, the surgeon must closely restore the basic functions and properties of the surgical flap and adjacent tissue. All options within the reconstructive ladder should be considered.

Modal decomposition method for acoustic impedance testing in square ducts.

Accurate duct acoustic propagation models are required to predict and reduce aircraft engine noise. These models ultimately rely on measurements of the acoustic impedance to characterize candidate engine nacelle liners. This research effort increases the frequency range of normal-incidence acoustic impedance testing in square ducts by extending the standard two-microphone method (TMM), which is limited to plane wave propagation, to include higher-order modes.
