Acute Pancreatitis I: Introduction

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...

Acute Pancreatitis I: Introduction

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Bacterial Gastroenteritis

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...

Acute Pancreatitis II: Clinical Manifestations and Management

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...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Gastritis III: Clinical Manifestations and Management

Gastritis III: Clinical Manifestations and Management

The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Summary

Eosinophilic gastroenteritis can cause stomach and intestinal wall thickening, mimicking other acute abdomen conditions on CT scans. Eosinophil counts confirmed the diagnosis, preventing unnecessary surgery in one patient.

Area of Science:

Gastroenterology
Radiology
Pathology

Background:

Computed tomography (CT) is crucial for diagnosing acute abdomen.
Eosinophilic gastroenteritis (EG) is an uncommon inflammatory condition.

Observation:

Two cases of EG presented with CT findings of mural thickening in the stomach, duodenum, and/or proximal jejunum.
These CT findings can be mistaken for other causes of acute abdomen.

Findings:

Elevated eosinophil counts were key to diagnosing EG.
CT findings of mural thickening in EG are specific.

Implications:

Accurate diagnosis of EG via eosinophil count can prevent misdiagnosis and unnecessary surgical intervention.
Radiologists and clinicians should consider EG in the differential diagnosis of acute abdomen with characteristic CT findings.
