Insights

West syndrome, a key cause of developmental disorders, has an estimated prevalence of 0.16 per 1000 children under two. This study provides crucial data for child neurology and public health in Japan.

Area of Science:

  • Pediatric Neurology
  • Developmental Pediatrics
  • Public Health

Background:

  • West syndrome is a significant cause of childhood developmental disorders.
  • Limited data exists on West syndrome prevalence in Japan's general population.
  • Accurate prevalence and incidence rates are vital for child neurology and public health planning.

Purpose of the Study:

  • To determine the prevalence rate of West syndrome in Okayama Prefecture, Japan.
  • To address the scarcity of population-based data on West syndrome in Japan.

Main Methods:

  • A population-based survey was conducted in Okayama Prefecture in 1994.
  • The study identified cases of West syndrome in the population under 2 years of age.

Main Results:

  • The total population under 2 years in Okayama Prefecture in 1994 was 37,085.
  • Six cases of West syndrome were identified.
  • The prevalence rate of West syndrome was calculated to be 0.16 per 1000.

Conclusions:

  • The study established a prevalence rate for West syndrome in a Japanese population.
  • This data is essential for understanding the public health impact of West syndrome and informing clinical practice in child neurology.

Factors Affecting Illness01:18

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...
Introduction to Epidemiology01:26

Introduction to Epidemiology

Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...
Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health condition at a...
Principles of Disease Surveillance01:26

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
Investigation of Disease Outbreaks01:23

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
