Microtubule Instability02:17

Microtubule Instability

5.5K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

117
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Venous Thrombosis I: Introduction

100
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Relative Risk01:12

Relative Risk

721
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

108
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

132
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Wrist Biomechanics

Background:

  • Perilunate dislocations and fracture-dislocations are uncommon wrist injuries resulting from significant trauma.
  • These injuries often involve complex ligamentous disruptions and associated fractures, demanding careful evaluation.

Observation:

  • A case report details a volar fracture-dislocation of the scaphoid's proximal pole.
  • This was associated with scapholunate and lunotriquetral ligament disruptions.
  • A lunate fossa fracture of the distal radius was also noted.

Findings:

  • The presented case exemplifies a severe perilunate injury pattern.
  • It underscores the intricate mechanics and potential for multiple concurrent injuries in high-energy wrist trauma.
  • Accurate radiographic assessment is crucial for identifying all components of the injury.

Implications:

  • Prompt and accurate diagnosis of these complex wrist injuries is vital for effective treatment.
  • Early intervention can mitigate the risk of long-term complications, such as chronic pain and instability.
  • This case emphasizes the need for thorough clinical and radiographic evaluation in suspected perilunate injuries.
