Summary
Dysphonia, or voice disorders, can persist in extremely preterm children despite some improvement. Individual voice quality varies, and further research is needed to understand these voice problems.
Area of Science:
- Pediatric Otolaryngology
- Neonatology
- Speech-Language Pathology
Background:
- Dysphonia is a recognized complication of preterm birth.
- Childhood voice disorders often resolve spontaneously, but prognosis is unknown for extremely preterm infants with laryngeal pathology.
- Neonatal intubation can lead to structural laryngeal issues and supraglottic hyperfunction, impacting voice quality.
Purpose of the Study:
- To assess the incidence and severity of dysphonia in children born at < 25 weeks' gestation.
- To evaluate changes in voice quality over time in this population.
- To explore individual variability in voice disorder progression.
Main Methods:
- Pilot study involving 10 extremely preterm children (9.67-17.08 years) undergoing repeat voice assessment.
- Primary outcome: Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) severity scores.
- Secondary outcomes: Acoustic Voice Quality Index and Pediatric Voice Handicap Index scores.
Main Results:
- Perceptual dysphonia severity scores significantly decreased on repeat assessment.
- No significant changes observed in objective voice measures or quality of life scores.
- Significant individual variation in CAPE-V scores (-36 to +1); no participant achieved normal voice quality.
Conclusions:
- Group data analysis masked considerable individual variability in voice disorder progression.
- Dysphonia appears persistent in extremely preterm children, with unknown underlying mechanisms for individual variation.
- Further research is crucial for understanding voice disorder progression and informing treatment.

2.0K
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

1.1K
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

1.1K
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
