Acute Pancreatitis II: Clinical Manifestations and Management01:30

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
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...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Summary

Point-of-care ultrasound (POCUS) can identify right-sided bowel wall edema in children, suggesting bacterial enteritis and helping differentiate it from appendicitis. This imaging can reduce unnecessary hospital resource use.

Area of Science:

  • Pediatric Emergency Medicine
  • Diagnostic Imaging
  • Gastroenterology

Background:

  • Abdominal pain in children often presents diagnostic challenges, particularly distinguishing diarrhea-related pain from appendicitis.
  • Right-sided bowel wall edema on ultrasound can be an indicator of enteritis.

Purpose of the Study:

  • To evaluate the utility of pediatric emergency department point-of-care ultrasound (POCUS) in identifying right-sided bowel wall edema.
  • To assess the correlation between POCUS findings and diagnoses of enteritis versus appendicitis in children.

Main Methods:

  • A retrospective case series of children with right-sided bowel wall edema identified via POCUS.
  • Review of hospital charts for clinical presentation, diagnostic workup, and outcomes.
  • Analysis of stool sample results for bacterial pathogens.

Main Results:

  • 113 children presented with right-sided small bowel wall edema on POCUS.
  • 31% were initially referred for appendicitis evaluation.
  • Bacterial enteritis (Campylobacter, Salmonella, Shigella) was confirmed in a significant portion of children with stool samples.
  • 40% were discharged after POCUS without further evaluation, and no cases of inflammatory bowel disease were subsequently diagnosed.

Conclusions:

  • Bowel wall edema on POCUS, in the absence of appendicitis signs, strongly indicates bacterial enteritis in pediatric patients.
  • Early POCUS can aid in differentiating enteritis from appendicitis, potentially reducing hospital resource utilization.
