Aerodynamic measurements such as vital capacity (VC), maximum phonation time (MPT) and the acoustic measurement Speaking Fundamental Frequency (SFF) are used commonly in Speech-language Pathology to aid in the assessment and treatment outcomes of vocal dysfunction. However, current research lacks analysis of the interaction across these parameters within males. This study examined the changes of these parameters and interactions in males across various age groups. Acoustic measures of SFF, MPT, and VC were obtained in age groups of 20-29, 30-39, 40-49, 50-59, and 60-69, N=35. Age and SFF were found to be statistically significant. No other statistically significant interactions were observed.

Aerodynamic measurements such as vital capacity (VC), maximum phonation time (MPT) and the acoustic measurement Speaking Fundamental Frequency (SFF) are used commonly in Speech-language Pathology to aid in the assessment and treatment outcomes of vocal dysfunction. However, current research lacks analysis of the interaction across these parameters within males and younger ages. This information may be important in understanding the normal changes in the speech mechanism with age and provide important direction for voice assessment and therapy outcomes. This study examined the changes of these parameters and interactions in males across various age groups. Acoustic measures of SFF, MPT, and VC were obtained in age groups of 20-29, 30-39, 40-49, 50-59, and 60-69, N=35. A statistically significant decrease in SFF with age was observed. No statistically significant interaction was observed between MPT and VC. Additionally, no statistically significant interaction was observed between MPT and age, or between VC and age. v

To date there are approximately 7,000 rare diseases. Most of these are derived from a genetic basis thus affecting the individual from birth or early childhood. Furthermore, many of these diseases affect multiple systems creating devastating effects on patient and family alike. For example, many of these rare diseases impact the patient's motor, cognitive and respiratory skills. Frequently, patients are unable to swallow safely. This may lead to aspiration pneumonia and even death. The slow turn around rate in precisely identifying and treating these diseases can have a significant impact on mortality. This chapter presents a summary of a rare disease, Plummer-Vinson syndrome (PVS). One of the main characteristics of PVS is the significant dysphagia (swallowing disorder) that occurs due to the presence of esophageal webs. PVS is discussed in terms of its history, etiology, epidemiology, clinical presentation, diagnosis, treatment and the significant impact on swallowing that results.
