Bleeding in Fresh Concrete01:22

Bleeding in Fresh Concrete

548
Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

Nursing Diagnosis

3.7K
Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Irritable Bowel Syndrome I: Introduction

939
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

759
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory Bowel Disease II: Crohn's Disease

987
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis

934
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Area of Science:

  • Gastroenterology
  • Diagnostic Imaging
  • Endoscopic Procedures

Background:

  • Small intestine bleeding (SIB) is an uncommon cause of acute gastrointestinal (GI) bleeding.
  • SIB accounts for most cases where bleeding sources remain unidentified after standard endoscopy or colonoscopy.
  • Diagnosing SIB is challenging, often leading to repeated transfusions, procedures, and hospital admissions, increasing healthcare costs.

Observation:

  • SBB presentation varies, with etiology influenced by patient age.
  • Aggressive resuscitation and prompt bleeding-site localization are often necessary for effective management.
  • Case presentation highlights the need for multiple imaging and endoscopic interventions to pinpoint bleeding sources.

Findings:

  • Common etiologies of SBB are age-dependent.
  • Radiologic modalities and endoscopic procedures are key diagnostic tools.
  • Successful SBB management relies on accurate etiology, available technology, and clinician expertise.

Implications:

  • Timely and accurate diagnosis of SBB can reduce patient morbidity and healthcare costs.
  • Advanced imaging and endoscopic techniques are vital for identifying elusive small bowel lesions.
  • Understanding diverse SBB etiologies guides tailored patient treatment strategies.
