Adult Stem Cells01:33

Adult Stem Cells

30.4K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Barrett Esophagus-II: Clinical Manifestations and Management

246
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

Barrett Esophagus-I: Introduction

154
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

Inflammatory Bowel Disease V: Surgical Management

184
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Esophageal Strictures-II: Clinical Features and Management

135
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

317
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Area of Science:

  • Gastroenterology
  • Pathology
  • Oncology

Background:

  • Colorectal juvenile polyps are typically non-neoplastic lesions predominantly observed in children and infants.
  • Their occurrence in individuals over 14 years old and adults is considered rare.

Observation:

  • A 75-year-old female patient presented with a pedunculated polyp in the transverse colon during colonoscopy.
  • The polyp, measuring approximately 2.5x2x1 cm, exhibited a reddish, fine-grained surface and dark red internal sections.

Findings:

  • Histopathologic analysis revealed irregularly distributed, some cystically dilated glands coated with normal intestinal epithelium.
  • The polyp's surface showed erosion and granulation tissue, with signs of hemorrhagic infarction in the stroma.
  • The histopathologic characteristics were consistent with a juvenile polyp.

Implications:

  • This case underscores the rare presentation of juvenile polyps in elderly patients.
  • It emphasizes the importance of thorough histopathologic evaluation for colorectal polyps, regardless of patient age.
  • The findings contribute to the understanding of the atypical occurrence of juvenile polyps in adults.
