Insights

Pediatric-onset multiple sclerosis (POMS) affects 2.85% of MS cases, predominantly females, with prevalence increasing after age 15. Blurred vision is the most common initial symptom in POMS patients.

Area of Science:

  • Neurology
  • Epidemiology
  • Immunology

Background:

  • Multiple sclerosis (MS) is a chronic immune-mediated inflammatory disease.
  • Pediatric-onset MS (POMS) is defined as MS with onset before age 18.
  • Understanding POMS clinical and epidemiological aspects is crucial for early diagnosis and management.

Purpose of the Study:

  • To determine the clinical and epidemiological characteristics of POMS in East-Azerbaijan province.
  • To establish the prevalence and incidence of POMS in the studied region.
  • To identify common presenting symptoms and demographic factors in POMS.

Main Methods:

  • A population-based study utilizing data from the sole MS registry center in East-Azerbaijan province.
  • Inclusion of POMS patients diagnosed by McDonald's criteria by the end of 2017.
  • Data collection focused on demographic information, age of onset, family history, diagnostic delay, and initial clinical presentations.

Main Results:

  • POMS accounted for 2.85% of all MS cases (85 out of 2976).
  • The regional prevalence of POMS was 11.67 per 100,000, with a significantly higher prevalence in females (18.94 per 100,000) compared to males (4.80 per 100,000).
  • The mean age of onset was 15.81 years, with 71.76% diagnosed between 16-17 years old. Blurred vision was the most frequent initial symptom (43.75%).

Conclusions:

  • Pediatric-onset MS is not rare and predominantly affects females.
  • POMS prevalence rises notably after age 15.
  • Blurred vision is the typical first clinical manifestation of POMS.

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
