Frozen microtitration trays manufactured by Micro-Media Systems (MMS) for antimicrobial testing of anaerobic bacteria were evaluated and compared with the broth disk elution method of Virginia Polytechnic Institute (VPI) described by Wilkins and Thiel. A total of 224 clinical anaerobic isolates were tested. Susceptibility results were compared for carbenicillin, cefoxitin, chloramphenicol, clin...

Purpose: Comprehensive evaluation of velopharyngeal insufficiency (VPI) typically includes auditoryperceptual assessment, nasometry, and anatomical evaluations. At times, these examinations are limited by the resources, invasiveness, time and expertise required to perform them. In such instances, the mirror-fogging test would be an ideal screening tool for VPI as it can be performed simply and ...

Velopharyngeal insufficiency (VPI) can occur in the setting of an unrepaired or repaired cleft lip and palate. The rate of VPI has been documented as high as 33% in some studies with higher rates of recurrences following surgery associated with genetic syndromes such as 22q11.2 deletions. The primary cause of VPI in these groups is still identified as the anatomic abnormalities of the velum. In...

Recently introduced frequency modulation (FM) systems provide an adaptive adjustment to the emphasis of the FM system through the user’s hearing aid via VoicePriority iTM (VPi). VPi measures the noise level at the listener’s hearing aid microphone and adds gain to the FM signal when the background noise increases to a detrimental level. However, the potential benefi t of VPi technology has yet ...

OBJECTIVE To determine if quality of life (QOL) is affected in children with velopharyngeal insufficiency (VPI). DESIGN Interview and survey. SETTING Two university pediatric ambulatory centers. PARTICIPANTS This population-based sample included 58 children, aged 5 to 17 years, and their parents; 29 of the children were diagnosed as having VPI and 29 were age-matched normal controls. IN...

Kang et al. [1] reported that visceral pleura invasion (VPI) was a factor of poor prognosis in T2 non-small cell lung cancer (NSCLC). In a previous study [2], we already stressed the poor prognosis of VPI which we also found correlated with more extensive mediastinal lymph node (LN) involvement and decreased survival rates. Contrary to these authors, we observed VPI to be more frequent in case ...

Introduction. Controversy exists over whether tonsillectomy will affect speech in patients with known velopharyngeal insufficiency (VPI), particularly in those with cleft palate. Methods. All patients seen at the OHSU Doernbecher Children's Hospital VPI clinic between 1997 and 2010 with VPI who underwent tonsillectomy were reviewed. Speech parameters were assessed before and after tonsillectomy...

Standard models of agency theory typically assume that the principal has considerable information about the preferences of the agent. Once this assumption is relaxed, the question arises whether the principal should try to obtain additional information about the agent’s preferences. In this paper we introduce the concept of a Value of Preference Information (VPI), which describes the benefits t...

BACKGROUND Visceral pleural invasion (VPI) is generally considered a poor prognostic factor in non-small cell lung cancer (NSCLC). VPI is defined as penetration beyond the elastic layer of visceral pleura (PL1), including the visceral pleural surface without the involvement of adjacent structures (PL2) by cancer cells. The aim of this study was to evaluate the influence of the extent of VPI on ...

OBJECTIVE To develop a protocol linking cine magnetic resonance (MR) imaging to simultaneously acquired audio recordings of specific phonatory tasks to evaluate velopharyngeal insufficiency (VPI) in children. DESIGN Institutional review board-approved development and application of a novel dynamic cine MR imaging protocol linked to simultaneously recorded audio. SETTING A tertiary care mult...
