Insights

Severe viral croup in children is linked to age between 12-24 months and fever. Identifying these risk factors helps guide steroid therapy for hospitalized Malaysian children with viral croup.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Epidemiology

Background:

  • Viral croup is a common respiratory illness in children.
  • Identifying risk factors for severe cases is crucial for timely intervention.

Purpose of the Study:

  • To determine risk factors for severe viral croup in hospitalized Malaysian children.
  • To identify predictors for severe outcomes in pediatric viral croup.

Main Methods:

  • Retrospective review of medical records for children under five diagnosed with viral croup (1994-1999).
  • Severe viral croup defined by specific clinical signs (stridor, recession, cyanosis, altered consciousness).
  • Multivariate logistic regression analysis to identify associated risk factors.

Main Results:

  • 14.7% of 122 children experienced severe viral croup.
  • Risk factors for severe disease included older age (12-24 months) and presence of fever.
  • Older children (16.8 vs 12.6 months) and shorter illness duration (1.7 vs 2.3 days) were noted in severe cases.
  • Ventilation was required in only 2.5% of severe cases.

Conclusions:

  • Age between 12-24 months and fever are significant risk factors for severe viral croup.
  • Early recognition of these factors can guide the selection of children for steroid therapy.
  • The overall prognosis for hospitalized viral croup cases remains favorable.

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Respiratory Syncytial Virus Disease01:29

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...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
