Alma Normalization Rules: The Basics and Beyond

Alma normalization rules are a powerful tool for editing and enhancing bibliographic and holding records, in batch or individually. This presentation will describe how to read and write normalization rules for beginner and intermediate users. We will cover the syntax and logic of normalization rules, how and why to add a rule as a process, common use cases and real-world examples, and best practices and tricks we’ve learned along the way. No programming experience is necessary for this session. At the end of the session, attendees will understand the basic syntax of normalization rules, how to interpret a normalization rule, and how to write normalization rules of moderate complexity

Reliability of GRBAS evaluation of voice quality in children who have a history of airway reconstruction surgery and how this compares to parental report of voice-related quality of life

Voice evaluation includes laryngoscopy, perceptual judgement of voice quality, evaluation of respiratory function, acoustic analysis of the voice signal and patient reported subjective impact of voice on quality of life. This is recommended in adults (Dejonkere et al 2001) and children (Cohen et al 2012). Perceptual evaluation of voice often follows the CAPE-V (ASHA 2002) or GRBAS (Hirano 1981). Children requiring laryngotracheal reconstruction (LTR) surgery tend to have this procedure during infancy, where subglottic stenosis forms following intubation in medically fragile or premature infants. Clinicians require reliable measures, particularly where there is a degree of subjectivity. Aspects of the CAPE-V show a high degree of reliability in rating of severity, pitch, breathiness and roughness (Krival et al 2007, Kelchner et al 2008). UK clinicians favour the GRBAS though there is little published information about reliability in a paediatric population. Comparison of clinician perceptual evaluation with patient report shows weak agreement in adults (Karnell et al 2006) reinforcing the need for both measurements. The extent to which the same is the case in children needs further exploration

Library of Congress Genre-Form Thesaurus (LCGFT) for Moving Images: Best Practices

The purpose of this document is to provide guidelines, with examples, for the usage of Library of Congress Genre/Form Terms for Library and Archival Materials (LCGFT) for moving image materials. These guidelines are intended to complement existing official guidelines. As genre/form practice in general is currently being reviewed by several other committees, these guidelines will need to be revisited in the future; however, these best practices fulfill the need for short-term guidance

Laryngoscopic and acoustic voice data of children following laryngo-tracheal reconstruction and cricotracheal resection surgery : a long term follow up

Objectives: Laryngeal airway narrowing from subglottic stenosis (SGS) may be congenital or acquired, with many cases of SGS acquired following intubation or laryngotracheal injury. Two main approaches to reconstructive surgical management exist: laryngotracheal reconstruction (LTR) and partial cricotracheal resection (CTR). Primary surgical outcome indicators continue to be survival or decannulation of the tracheostomy. LTR and CTR procedures have been undertaken in Glasgow since the early 1980s. A retrospective audit of parents’ perspectives on quality of life for their children showed overwhelming concerns relating to breathing, respiratory tract infections and voice quality in their children; in addition to concerns relating to independence and the ability to lead a normal life. This study evaluated the voice outcomes of children over the age of 5 who have had LTR/CTR at the hospital in Glasgow. This paper explores specifically the laryngeal vibratory mechanisms used by children who have undergone LTR or CTR in order to produce voice and how this relates to acoustic features of voice for each child compared to published normative acoustic data for an English speaking paediatric/adolescent population. Methods: Participants were recruited through a cohort analysis. All surviving children who had undergone LTR or CTR at the hospital and were >5years (n = 56) were invited to take part in this study through postal information leaflets. 16 participants opted in to the study, 12 attended for data collection appointments, 1 withdrew participation and 3 failed to attend the appointment. Awake laryngoscopy and voice recordings were taken for each participant. Audio recordings followed a standard protocol where each child produced a single sustained vowel sound [a] four times. The audio recordings took place in a sound-proofed audiology room located in the children’s hospital to reduce the impact of background noise on the stability of the audio files. Acoustic analysis was performed from the recording of the sustained vowel [a] using the acoustic analysis software Multi-Dimensional Voice Programme (MDVP). Fundamental frequency and three perturbation measures (jitter percentage, shimmer percentage and noise to harmonic ratio) were measured from the middle 3.5 seconds of the voiced segment produced in the fourth recording. Results: There was a range of vibratory mechanisms observed in all of the participants. For four children, all the acoustic analysis findings were within the normal range. These four participants are discussed in relation to the laryngeal visualisation observations. Conclusions: Normal voice outcome is a potential outcome for children evaluated long term following LTR/CTR. The extent to which these outcomes relates to initial surgical intervention is worthy of exploration

Cross-sectional follow up of voice outcomes in children who have a history of airway reconstruction surgery

Objectives - This study reports vocal function in a cross-section of children with subglottic stenosis. Each child had a history of laryngotracheal reconstruction and/or cricotracheal resection surgery. Vocal function was measured using laryngoscopy, acoustic analysis, perceptual evaluation and impact of voice on quality of life.  Design - All patients aged >5 years with history of laryngotracheal reconstruction and/or cricotracheal resection surgery at the Scottish National Complex Airways service were invited to participate.  Setting - Data was gathered in the Royal Hospital for Children in Glasgow in a single out-patient appointment. Participants - Twelve out of fifty-six former patients (aged 5 – 27) provided a voice sample and eleven consented to awake laryngoscopy. All consented for detailed evaluation of their medical records.  Main outcome measures - Acoustic analysis of fundamental frequency and pitch perturbation was conducted on sustained vowel [a]. Perceptual evaluation was conducted by four trained listeners on a series of spoken sentences. Impact on quality of life was measured using the Paediatric Voice Related Quality of Life questionnaire. Laryngeal function was descriptively evaluated.  Results - Four children had normal voice acoustically, perceptually and in relation to voice related quality of life. One of these had vocal fold nodules unrelated to surgical history. Two other children had ‘near normal’ vocal function, defined where most voice measurements fell within the normal range.  Conclusions - Normal or ‘near normal’ voice is a possible outcome for children who have had this surgery. Where there is an ongoing complex medical condition, voice outcome may be poorer
