Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

1.3K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Spinal Nerves: Plexus II

852
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.7K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Rheumatic Heart Disease I: Introduction

40
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease IV: Nursing Management

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...

Endocarditis II: Clinical Features of Infective Endocarditis

25
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...

Area of Science:

  • Rheumatology
  • Infectious Diseases
  • Neurology

Background:

  • Rheumatoid nodules are typically benign and asymptomatic.
  • Atypical presentations can pose diagnostic challenges.

Observation:

  • A patient presented with a rapidly enlarging, painful elbow mass causing posterior interosseous nerve (PIN) palsy.
  • Histological examination revealed features of a rheumatoid nodule with neutrophilic infiltration, suggesting superimposed infection.

Findings:

  • Despite initial negative cultures, the lesion recurred aggressively.
  • Subsequent pathogen isolation confirmed infection.
  • Adjusting immunosuppressive therapy and administering antibiotics resulted in long-term remission and functional recovery.

Implications:

  • Distinguishing infection from rheumatoid activity is crucial in atypical rheumatoid nodule presentations.
  • This case emphasizes the need for a high index of suspicion for infection in rapidly progressing rheumatoid nodules.
  • Multidisciplinary management is key for optimal outcomes in complex cases.
