Pediatric Palliative Care at Home: A Prospective Study on Subcutaneous Drug Administration.

Context: The subcutaneous route is a useful alternative for drug administration in palliative care. Although there is scientific evidence on its use in adult patients, the literature in pediatric palliative care is almost nonexistent.

Objectives: To describe the experience of a pediatric palliative care unit (PPCU) with in-home subcutaneous drug administration symptom control.

Quality of the singing voice in sopranos. Influence of the text and the musical accompaniment in the opera singing.

Introduction And Objectives: Opera singing voice uses different technical tools for artistic purposes. We want to define if the quality of the sung sound is affected by an aware work on the musical accompaniment and the text. We analyse the acoustic signal and the subjective perception.

Laryngeal electromyography, a useful tool in difficult cases of pediatric laryngeal mobility disorders.

Introduction: Pediatric laryngeal mobility disorders constitute a challenge in terms of diagnosis and treatment, especially in small children and those complex patients with prior history of prolonged intubation or surgery. Laryngeal electromyography (L-EMG) may help to distinguish vocal fold paralysis from fixation.

Material And Methods: Ten children with laryngeal mobility disorders (including bilateral vocal fold immobility (BVFI) or unilateral vocal fold immobility (UVFI) with contralateral hypomobility) underwent suspension laryngoscopy and L-EMG between July 2019 and March 2021.

Vocal fold immobility with normal LEMG: A range of possibilities.

Objective: The objective of this paper is to study the etiology of vocal fold immobility with non-pathological LEMG.

Methods: A retrospective study was performed on patients who presented with vocal fold immobility and underwent LEMG from 2009 to 2017. Those patients with normal LEMG findings were selected.

Is Immobile vocal fold Related to the Spinal Accessory Nerve Agenesis?: A Case Report.

The spinal accessory nerve innervates the sternocleidomastoid and trapezius muscles, but the internal branch from the spinal accessory nerve is also contributing to the motor innervation of the larynx. For the first time, we report a case of an impairment of sternocleidomastoid, trapezius, and thyroarytenoid muscles from the same side. In our case, the anatomical variant that can explain this situation implies the cranial roots and some fibers from the spinal roots of the spinal accessory nerve to form the internal branch.

Clinical experience with patients with spasmodic dysphonia and primary Meige syndrome.

Introduction: Meige syndrome (MS) is part of the group of segmental cranial dystonias, which affect more than two cranial muscle groups. Specifically, blepharospasm is associated with another cranial dystonia (oromandibular, cervical or laryngeal). The aim of this paper was to report our experience in patients with spasmodic dysphonia (SD) associated with primary MS.

[Off-label and unlicensed drug use: Results from a pilot study in a pediatric intensive care unit].

Purpose: To analyze the prevalence of use of off-label and unlicensed drugs in a pediatric intensive care unit of a University Hospital.

Method: An observational, descriptive, prospective six week pilot study in a Pediatric Intensive Care Unit. Hospitalized patients aged between 0 and 18 years were included.

Laryngeal Electromyography for Prognosis of Vocal Fold Paralysis.

Objective: This study aimed to determine the value of laryngeal electromyography in the prognosis of vocal fold paralysis.

Study Design: This is a retrospective descriptive study.

Diagnosis and management with botulinum toxin in 11 cases of laryngeal synkinesis.

Laryngeal synkinesis is a vocal fold movement disorder produced by a misdirected reinnervation after a recurrent laryngeal nerve injury. Its symptoms differ greatly between patients, requiring diverse therapeutical approaches. We aim to describe our experience in the diagnosis and treatment of different laryngeal synkinesis presentations.

Validation of the Spanish adaptation of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V).

Objective: The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was developed.to promote a standardised approach to evaluating and documenting auditory perceptual judgments of vocal quality. This tool was originally developed in English language and its Spanish version is still inexistent.

Paediatric vocal fold paralysis.

Introduction And Objectives: Vocal fold paralysis (VFP) is a relatively common cause of stridor and dysphonia in the paediatric population. This report summarises our experience with VFP in the paediatric age group.

Methods: All patients presenting with vocal fold paralysis over a 12-month period were included.

[Laryngeal electromyography in diagnosis and treatment of voice disorders].

Introduction And Objectives: Laryngeal electromyography, together with clinical evaluation, is a valuable tool in voice disorder management. It assesses the integrity of laryngeal nerves and muscles, contributing to the diagnosis of many diseases, especially laryngeal movement disorders. Our purpose was to describe the experience of the first Spanish series with laryngeal electromyography in evaluating voice disorders.

Developing a drug library for smart pumps in a pediatric intensive care unit.

Background: The most serious medication errors occur during intravenous administration. The potential consequences are more serious the more critical and younger the patient. Smart pumps can help to prevent infusion-related programming errors, thanks to associated dose-limiting software known as "drug library".

[The effect of anchor voices and visible speech in training in the GRABS scale of perceptual evaluation of dysphonia].

Introduction: Perceptual evaluation of voice quality remains a key standard for judgment of vocal impairment. The GRABS method has become a commonly-used scale for rating severity of dysphonia, but it has no published, standardised protocol to follow. Training is important for reaching good interrater agreement for its parameters; however, the references most often cited for the GRABS provide no guidelines for clinical administration, speech material or rating calibration.

[Type III thyroplasty for the treatment of high-pitched voice disorder].

Type III thyroplasty is a surgical technique which diminishes the fundamental frequency of the voice. We present the case of a patient with dysphonia by tone elevation in relation to gender, treated by type III thyroplasty and an updated review of the surgical technique and its outcome.

[Validation of the Spanish version of the voice handicap index for vocal singing (SVHI)].

Unlabelled: In the questionnaires that currently exist in Spanish to assess the impact on quality of life of voice pathology, there are no questions that refer specifically to the singing voice. We present the results of the validation of the Singing Voice Handicap Index (SVHI) in Spanish.

Materials And Methods: The SVHI was translated into Spanish from the validated version in English.

[The singing voice].

Singing voice is a special subgroup within the field of voice. In addition to the differences in physiology between singing and speaking voice, singer patients are often regarded as a challenge for the otolaryngologist. The reason for this is probably that the field of voice has not received as much attention as others in our speciality.
