Insights

Children with grass pollen allergies are not at higher risk for acute rhinosinusitis. This study found comparable incidence rates between allergic and non-allergic children, suggesting pollen-induced rhinitis is a minor risk factor.

Area of Science:

  • Pediatric Allergy and Immunology
  • Otolaryngology

Background:

  • Grass pollen-induced rhinitis is common in children.
  • Acute rhinosinusitis is a frequent pediatric condition.
  • The relationship between allergic rhinitis and acute rhinosinusitis requires further investigation.

Purpose of the Study:

  • To determine the incidence of acute rhinosinusitis in children with grass pollen-induced rhinitis.
  • To compare this incidence with that in non-allergic children during grass pollen season.

Main Methods:

  • A prospective study involving children with grass pollen-induced rhinitis and a control group of non-allergic children.
  • Daily symptom diaries were maintained by parents to record nasal symptoms and medication use.
  • Diagnosis of acute rhinosinusitis was confirmed via fibro-endoscopy when suspected.

Main Results:

  • The incidence of acute rhinosinusitis was 7.0% in children with grass pollen-induced rhinitis and 4.6% in the control group (p=0.49).
  • Children with acute rhinosinusitis experienced more symptom days and/or higher symptom scores compared to those without.

Conclusions:

  • Endoscopically confirmed acute rhinosinusitis incidence is comparable between children with and without grass pollen-induced rhinitis.
  • Grass pollen-induced rhinitis appears to be a negligible risk factor for developing acute rhinosinusitis.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Seasoning of Wood01:15

Seasoning of Wood

Seasoning of wood is a crucial process aimed at reducing and stabilizing the moisture content within the wood to prevent future shrinkage, structural damage, or aesthetic issues once the wood is used in construction. Wood naturally swells when it absorbs moisture and contracts as it dries.
Achieving equilibrium moisture content is the goal of seasoning; this is the point where the wood's moisture content stabilizes to align with the moisture levels of the surrounding environment. Proper...

Biological Clocks and Seasonal Responses02:45

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Relative Risk01:12

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
