Anesthetic Implications of Previously Undiagnosed Temporomandibular Joint Ankylosis: A Case Report.

Temporomandibular joint (TMJ) ankylosis is characterized by bony fusion that limits TMJ mobility. We present the case of an elderly woman who was brought to the operating room for dental rehabilitation under general anesthesia. The patient had an undiagnosed TMJ ankylosis, which was discovered only after induction of anesthesia due to her nonverbal status and advanced dementia.

Left ventricular filling pressure in Tetralogy of Fallot: Correlation between invasive and noninvasive indices.

Background: Left heart filling pressures, as measured by pulmonary artery wedge pressure (PAWP), is associated with heart failure related mortality. Because of the prognostic importance of PAWP, several echocardiographic indices have been proposed for noninvasive assessment of PAWP. However, these indices have not been validated in the congenital heart disease population.

Assessment and Implications of Right Ventricular Afterload in Tetralogy of Fallot.

Patients with tetralogy of Fallot (TOF) have abnormal right ventricular (RV) afterload because of residual or recurrent outflow tract obstruction, often with abnormal pulmonary artery (PA) vascular function. The purpose of this study was to determine if RV afterload was independently associated with death and/or heart transplant in patients with TOF. This is a retrospective study of TOF patients that underwent cardiac catheterization for clinical indications at Mayo clinic between 1990 and 2015.

Counterbalancing Regulation in Response Memory of a Positively Autoregulated Two-Component System.

Fluctuations in nutrient availability often result in recurrent exposures to the same stimulus conditions. The ability to memorize the past event and use the "memory" to make adjustments to current behaviors can lead to a more efficient adaptation to the recurring stimulus. A short-term phenotypic memory can be conferred via carryover of the response proteins to facilitate the recurrent response, but the additional accumulation of response proteins can lead to a deviation from response homeostasis.
