Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

295
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Nature and Nurture

22.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

The Fossil Record02:56

The Fossil Record

27.4K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Summary
This summary is machine-generated.

Nearly all microtia patients exhibit soft palate dysfunction (SPD), leading to velopharyngeal insufficiency (VPI). This study highlights the prevalence of VPI in microtia, impacting speech development.

Area of Science:

  • Otolaryngology
  • Pediatric Speech Pathology
  • Craniofacial Anomalies

Background:

  • Microtia is often linked to hearing loss, but palatal dysfunction is a common, overlooked issue.
  • Soft palate dysfunction (SPD) and velopharyngeal insufficiency (VPI) are frequently observed in microtia patients.
  • Understanding the prevalence of SPD and VPI is crucial for addressing speech impediments in microtia.

Purpose of the Study:

  • To determine the prevalence of soft palate dysfunction (SPD) and velopharyngeal insufficiency (VPI) in patients with microtia.
  • To investigate the correlation between microtia's clinical characteristics and the occurrence of SPD and VPI.
  • To establish a link between palatal dysfunction and audiological/craniofacial findings in microtia.

Main Methods:

  • A prospective cohort study involving 67 microtia patients and 30 controls.
  • Oral examinations assessed palate movement, and the mirror-fogging test evaluated nasal escape.
  • Correlations were analyzed between microtia severity, middle ear development, mandibular shift, syndromes, and palatal dysfunction/VPI.

Main Results:

  • 96% of microtia patients presented with SPD; 60% (unilateral) and 85% (bilateral) showed VPI.
  • Bilateral microtia cases often exhibited minimal soft palate movement (59%).
  • SPD correlated significantly with mirror-fogging tests, middle ear underdevelopment, and microtia severity. VPI grade correlated with mandibular shift and syndrome presence.

Conclusions:

  • This study is the first to document VPI stemming from SPD in both isolated and non-isolated microtia.
  • The findings underscore the high prevalence of palatal dysfunction in microtia patients.
  • SPD and VPI are significant factors contributing to speech issues in microtia, necessitating targeted interventions.
