Liver Histology01:27

Liver Histology

4.4K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Liver Physiology

3.8K
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Liver Regeneration

4.3K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

2.1K
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

Diseases of the Liver and Gallbladder

2.0K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

201
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Area of Science:

  • Infectious Diseases
  • Hepatology
  • Nephrology

Background:

  • Citrobacter koseri is an uncommon pathogen, rarely implicated in liver abscess formation.
  • Previous reports of C. koseri liver abscesses primarily involved diabetic patients.
  • Comorbidities like chronic kidney disease may increase susceptibility to C. koseri infections.

Purpose of the Study:

  • To report a rare case of Citrobacter koseri liver abscess with concurrent bacteremia in an elderly male with chronic kidney disease.
  • To emphasize the importance of considering C. koseri as a causative agent for liver abscesses in immunocompromised individuals.
  • To highlight the successful management strategy for such infections.

Main Methods:

  • Case report of an elderly male patient presenting with non-specific symptoms.
  • Diagnostic workup included abdominal ultrasound and blood cultures.
  • Treatment involved a combination of antibiotics and abscess drainage.

Main Results:

  • The patient was diagnosed with a liver abscess and C. koseri bacteremia.
  • Ultrasound confirmed the presence of a liver abscess.
  • Blood cultures yielded growth of Citrobacter koseri.
  • The patient responded well to antibiotic therapy and surgical drainage.

Conclusions:

  • Citrobacter koseri can cause liver abscesses, even in patients without diabetes, particularly those with comorbidities like chronic kidney disease.
  • Early diagnosis and combined treatment with antibiotics and drainage are crucial for managing C. koseri liver abscess and bacteremia.
  • Clinicians should maintain a high index of suspicion for abscesses, including liver abscesses, when C. koseri is isolated from patients with underlying health conditions.
