Endocarditis II: Clinical Features of Infective Endocarditis

735
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Chronic Kidney Disease I: Introduction

1.0K
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

896
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...

Chronic Kidney Disease II: Clinical Manifestations

909
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Inflammatory Bowel Disease II: Crohn's Disease

1.5K
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...

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Radiology

Background:

  • Lunate osteonecrosis (Kienböck disease) has seen significant advancements in understanding its causes, progression, and treatment over the last decade.
  • New classification systems have emerged, utilizing advanced imaging for lunate viability assessment and arthroscopic evaluation of cartilage status.

Purpose of the Study:

  • To review the latest literature on Kienböck disease.
  • To introduce a new, comprehensive treatment algorithm for lunate osteonecrosis.

Main Methods:

  • Literature review of recent studies on Kienböck disease.
  • Development of a treatment algorithm integrating multiple classification systems.

Main Results:

  • The review synthesizes current knowledge on etiology, natural history, and treatment of lunate osteonecrosis.
  • The proposed algorithm combines traditional osseous classification with new perfusion/viability and articular cartilage classifications.

Conclusions:

  • A multi-faceted classification approach is crucial for managing Kienböck disease.
  • The new algorithm offers a structured framework for guiding treatment decisions in lunate osteonecrosis.
