To explore how the different metrics of obesity, specifically body mass index (BMI), Mallampati, neck circumference, waist circumference, and waist-hip ratio, correlate with metrics of sleep disordered breathing (SDB), specifically the apnea/hypopnea index (AHI), and which is/are the most likely to predict and correlate with SDB. ⋯ Obesity correlates with SDB severity. Waist circumference is a better measure than BMI or neck circumference to predict SDB. Men and women are anthropometrically different. Even with an AHI of 5 or more, only half of SDB patients in this study were clinically obese. An abnormal waist circumference for men and women is 102 cm (40 inches) or more.

Randomized Controlled Trial
Responses to trigeminal irritants at different locations of the human nasal mucosa.
Previous work suggests differences in the distribution of human intranasal trigeminal receptors. The aim of this study was to investigate these topographic differences for different concentrations of different trigeminal irritants using an electrophysiologic measure of trigeminal activation, the negative mucosa potential (NMP). ⋯ In agreement with previous work, the present data suggest that there are topographic differences in the responsiveness of the mucosa to chemical irritants.

Swallowing dysfunction is a devastating complication of chemoradiation therapy (CRT) for head and neck squamous cell carcinoma. We have previously demonstrated that pretreatment swallowing exercises improve posttreatment swallowing-related quality of life. This study evaluates the effect of pretreatment swallowing exercises on posttreatment swallow function as measured by videofluoroscopy. ⋯ Performing pretreatment swallowing exercises produces measurable improvements in posttreatment swallowing function in patients who undergo organ-preservation CRT for head and neck cancer. This study provides an initial foundation for the development of noninvasive, cost-effective, evidence-based interventions in this group of vulnerable patients.

Comparative Study
Resolving feeding difficulties with early airway intervention in Pierre Robin Sequence.
To observe rates of gastrostomy tube (g-tube) placement in Pierre Robin Sequence (PRS) and to determine whether relieving airway obstruction solves feeding difficulties. ⋯ In children with iPRS, feeding difficulties can be resolved with early airway intervention. Delaying airway intervention may necessitate feeding assistance because all of the iPRS children who required a g-tube fell into this category. The presence of additional disorders and syndromes further complicates treatment because most of the sPRS children required g-tubes regardless of airway intervention.

Study and detailed description of the large connections between the normally recurrent inferior laryngeal nerve (RILN) and the sympathetic trunk (ST) because these may be mistaken for a nonrecurrent inferior laryngeal nerve (NRILN). ⋯ 1) The CB between the RILN and the ST may have a diameter and course similar to an NRILN and may be confused with it. 2) The occurrence of the CB is greater than the occurrence referred to in previous studies. 3) The occurrence of the CB is similar by side and sex. 4) The CB may arise at different levels from the cervical ST and ganglia and end in the thyroid area. 5) Other neural elements may also be confused with an RILN, such as the cardiac nerves and the collateral branches from an NRILN to the trachea and esophagus.
