Insights

Vestibular impairment is common in children with primary ciliary dyskinesia (PCD). Many cases of imbalance and vestibular issues in PCD patients go undiagnosed, highlighting a need for better screening.

Area of Science:

  • Pediatric otolaryngology
  • Genetics
  • Neurology

Background:

  • Primary ciliary dyskinesia (PCD) is a rare genetic disorder causing respiratory issues.
  • Middle ear effusion is a common otologic manifestation of PCD.
  • The prevalence of vestibular impairment in children with PCD is not well-established.

Purpose of the Study:

  • To investigate the presence and extent of vestibular impairment in children diagnosed with PCD.
  • To determine if common genetic mutations in PCD are associated with vestibular dysfunction.

Main Methods:

  • A cross-sectional cohort study was conducted at a tertiary pediatric referral hospital.
  • Twenty-five children with confirmed PCD underwent clinical assessment and vestibular testing.
  • Tests included single-leg stance with eyes open/closed and video head impulse testing (vHIT).

Main Results:

  • Nineteen out of 25 (76%) children with PCD exhibited vestibular impairment.
  • Fifteen participants failed the single-leg stance test, and six had abnormal vHIT results.
  • The DNAH5 gene mutation was most common (32%) and strongly associated with vestibular impairment (87.5%).

Conclusions:

  • A significant majority of children with PCD experience vestibular impairment, often previously undiagnosed.
  • Vestibular pathology and imbalance may be under-diagnosed in the PCD population.
  • Routine vestibular screening is recommended for children with PCD.

Equilibrium and Balance01:15

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Vestibular System01:29

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Mechanism of Ciliary Motion01:05

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Microtubules in Signaling01:22

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
