Cirrhosis I: Introduction

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Detailed Structure and Function of Lymph Nodes

Detailed Structure and Function of Lymph Nodes

Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Secondary Lymphoid Organs

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Development of the Lymphatic System

Development of the Lymphatic System

The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Assessment of the Rectum and Anus

Assessment of the Rectum and Anus

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,...

Summary

This summary is machine-generated.

Schmorl's nodes (SNs) are common vertebral lesions, often asymptomatic. While the axial load model is favored, the exact cause of painful SNs remains unclear, with varied management options available.

Area of Science:

Spine imaging and pathology
Vertebral body disorders

Background:

Schmorl's nodes (SNs) involve nucleus pulposus herniation into vertebrae.
Most SNs are asymptomatic, but some cause pain.

Purpose of the Study:

To review the epidemiology, clinical presentation, pathogenesis, imaging, and management of Schmorl's nodes.

Main Methods:

Literature search of US National Library of Medicine and National Institutes of Health databases.

Main Results:

The axial load model has the most evidence for SN pathogenesis.
Symptomatic SNs may result from inflammation due to nucleus pulposus herniation.
Management ranges from conservative to surgical fusion.

Conclusions:

Schmorl's nodes are common and frequently asymptomatic.
Pathogenesis lacks consensus, and no standard treatment exists for symptomatic cases.
