Insights

Stridor in infants is often caused by common conditions like laryngomalacia. For atypical cases, neck X-rays and sometimes bronchoscopy help diagnose the cause of this upper airway noise.

Area of Science:

  • Pediatrics
  • Otolaryngology
  • Radiology

Background:

  • Stridor, a high-pitched breathing sound, is a frequent symptom in young children.
  • It results from turbulent airflow in the upper airway or trachea.
  • Common causes in infants (<12 months) include laryngomalacia, tracheomalacia, croup, foreign body aspiration, and retropharyngeal abscess.

Observation:

  • Atypical presentations of stridor may require advanced diagnostic imaging.
  • Soft tissue neck radiographs are a valuable tool for identifying the cause of stridor when the presentation is unusual.

Findings:

  • Radiographic evaluation can aid in determining the etiology of stridor.
  • In some cases, bronchoscopy may be necessary for definitive diagnosis and treatment planning.

Implications:

  • Early and accurate diagnosis of stridor is crucial for appropriate management in pediatric patients.
  • Utilizing imaging like neck radiographs can guide further interventions, potentially avoiding more invasive procedures.

Unusual Results01:16

Unusual Results

Unusual results are those that have a very low chance of occurring. Unusual results can be identified using probabilities and the range rule of thumb. In problems involving probability, unusual results can be observed in 2 instances – an unusually high number of successes or an unusually low number of successes.
According to the range rule of thumb, any value above or below two standard deviations, 2σ  from the mean, μ  is considered unusual.
Maximum unusual value =...

z Scores and Unusual Values01:07

z Scores and Unusual Values

The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
 This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

Drug Dosing: Infants and Children

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...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Network Covalent Solids02:18

Network Covalent Solids

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...

Electron Configuration of Multielectron Atoms

The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons. Since the core electron shells correspond to noble gas electron configurations, we can abbreviate electron...
