This video: Pericarditis is swelling and irritation of the pericardium, the thin sac-like membrane surrounding your heart. Pericarditis often causes chest pain and sometimes other symptoms. The sharp chest pain associated with pericarditis occurs when the irritated layers of the pericardium rub against each other. Pericarditis usually begins suddenly but doesn't last long (acute). When symptoms develop more gradually or persist, pericarditis is considered chronic. Most cases are mild and usually improve on their own. Treatment for more-severe cases may include medications and, rarely, surgery. Early diagnosis and treatment may help to reduce the risk of long-term complications from pericarditis.
Function and Anatomy: The hip is a ball and socket type joint, formed by the articulation of the head of the femur with the pelvis. Normal range of motion includes: abduction 45 degrees, adduction 20-30 degrees, flexion 135 degrees, extension 30 degrees, internal and external rotation. Hip pathology can cause symptoms anywhere around the joint, though frequently pain is anterior and radiates to the groin region. Additionally, pathology outside of the hip can be referred to this region. History and exam obviously help in making these distinctions.
The Knee Exam
Observation:
1. Make sure that both knees are fully exposed. The patient should be in either a gown or shorts. Rolled up pant legs do not provide good exposure!
2. Watch the patient walk. Do they limp or appear to be in pain? When standing, is there evidence of bowing (varus) or knock-kneed (valgus) deformity? There is a predilection for degenerative joint disease to affect the medical aspect of the knee, a common cause of bowing. Varus Knee Deformity, more marked on the left leg. 3. Make note of any scars or asymmetry. Chronic/progressive damage, as in degenerative joint disease, may lead to abnormal contours and appearance. Is there obvious swelling as would occur in an effusion? Redness suggesting inflammation? 4. Is there evidence of atrophy of the quadriceps, hamstring, or calf muscle groups? Knee problems/pain can limit the use of the affected leg, leading to wasting of the muscles.
While both legs have well developed musculature,
the left calf and hamstring are bulkier than the right. 5. Look at the external anatomy, noting structures above and below the knee itself: 1. Patella 2. Patellar tendon 3. Quadriceps/Hamstring/Calf muscles 4. Medial and lateral joint lines. 5. Femur and Tibia 6. Tibial tuberosity
Ballotment (helpful if the effusion is large) 1. Slightly flex the knee which is to be examined.
2. Place one hand on the supra-pateallar pouch, which is above the patella and communicates with the joint space. Gently push down and towards the patella, forcing any fluid to accumulate in the central part of the joint.
3. Gently push down on the patella with your thumb.
4. If there is a sizable effusion, the patella will feel as if it's floating and "bounce" back up when pushed down.
Electronystagmography (ENG) is a diagnostic test to record involuntary movements of the eye caused by a condition known as nystagmus. It can also be used to diagnose the cause of vertigo, dizziness or balance dysfunction by testing the vestibular system.
