Insights

Childhood lower respiratory infections like bronchiolitis, RSV, and pneumonia are common. Incidence was highest among Native Hawaiian and Pacific Islander infants, indicating a need for targeted public health strategies.

Area of Science:

  • Pediatric Infectious Diseases
  • Epidemiology
  • Public Health

Background:

  • Lower respiratory tract infections (LRTI) are a major global cause of childhood hospitalization and mortality.
  • Severe bronchiolitis, respiratory syncytial virus (RSV), and pneumonia represent significant pediatric LRTI burdens.

Purpose of the Study:

  • To determine the incidence and epidemiology of severe bronchiolitis, RSV, and pneumonia in children under 5 years old in Hawaii.
  • To identify demographic and temporal patterns of these infections within the Hawaiian pediatric population.

Main Methods:

  • Retrospective analysis of Hawaii State Inpatient Database from 1997-2004.
  • Inclusion criteria: Hawaii residents younger than 5 years diagnosed with bronchiolitis, RSV, or pneumonia.

Main Results:

  • Average annual incidence rates per 1000 children under 5: bronchiolitis (3.8), RSV (2.7), pneumonia (6.8).
  • Higher incidence in infants (<1 year), boys, and Native Hawaiian/other Pacific Islander children.
  • Peak hospitalizations occurred October-February; estimated annual charges exceeded $11.5 million.

Conclusions:

  • Overall incidence and hospitalization rates for these LRTI in Hawaii children were low compared to the general U.S. population.
  • However, hospitalization rates for Native Hawaiian and other Pacific Islander children were significantly higher than other racial groups.
  • Findings highlight disparities and suggest a need for culturally-tailored public health interventions.

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Acute Respiratory Failure-I01:21

Acute Respiratory Failure-I

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
Acute Respiratory Failure-III01:30

Acute Respiratory Failure-III

Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without causing...
