Pediatric Bilateral Vestibular Hypofunction: A Review of 26 Cases.

Objective: Peripheral bilateral vestibular hypofunction (BVH) is a rare condition that is well-studied in the adult population, whereas characterization in children has been limited. We report a pediatric cohort of patients with BVH at a multidisciplinary, tertiary care pediatric vestibular clinic.

Methods: A record review of 832 patients with balance-related complaints in our center was conducted.

Asymmetric Ocular Vestibular Evoked Myogenic Potentials in Pediatric Vestibular Migraine.

Objective: Although ocular vestibular evoked myogenic potentials (oVEMP) abnormalities have been associated with vestibular migraine (VM) in adults, no studies have evaluated this in pediatric patients with VM. oVEMP asymmetry with normal cervical VEMP (cVEMP) findings may be a reliable VM biomarker in adults. We characterize VEMP results among pediatric patients with VM and benign recurrent vertigo of childhood (BRVC), a migraine precursor, and compare these results with VEMP findings from pediatric patients with nonmigrainous vestibular diagnoses.

Excess of COVID-19 cases and deaths due to fine particulate matter exposure during the 2020 wildfires in the United States.

The year 2020 brought unimaginable challenges in public health, with the confluence of the COVID-19 pandemic and wildfires across the western United States. Wildfires produce high levels of fine particulate matter (PM). Recent studies reported that short-term exposure to PM is associated with increased risk of COVID-19 cases and deaths.

In situ evaluation of spatiotemporal distribution of doxorubicin from Drug-eluting Beads in a tissue mimicking phantom.

Understanding the intra-tumoral distribution of chemotherapeutic drugs is extremely important in predicting therapeutic outcome. Tissue mimicking gel phantoms are useful for studying drug distribution in vitro but quantifying distribution is laborious due to the need to section phantoms over the relevant time course and individually quantify drug elution. In this study we compare a bespoke version of the traditional phantom sectioning approach, with a novel confocal microscopy technique that enables dynamic in situ measurements of drug concentration.

Probabilistic approximation of effective reproduction number of COVID-19 using daily death statistics.

The effective reproduction number () which signifies the number of secondary cases infected by one infectious individual, is an important measure of the spread of an infectious disease. Due to the dynamics of COVID-19 where many infected people are not showing symptoms or showing mild symptoms, and where different countries are employing different testing strategies, it is quite difficult to calculate the , while the pandemic is still widespread. This paper presents a probabilistic methodology to evaluate the effective reproduction number by considering only the daily death statistics of a given country.
