Pericarditis

Pericarditis

The pericardium is a thin membrane surrounding the heart. When this membrance is swollen or disturbed, it leads to Pericarditis. The inflamed pericardium increases the lubricating fluid surrounding the heart, thereby laying pressure on the heart. Pericarditis usually occurs after a heart attack or trauma. Any tumor or auto-immune disease can also bring on pericarditis.

Acute pericarditis causes sudden pain. This happens when the pericardium brushes against the heart's outer layers. Bacterial, viral or fungal infections can bring on pericarditis. This sometimes leads to pus in the pericardial sac. Pericarditis that occurs after a heart attack or surgery is referred to as Dressler's syndrome. It is a body autoimmune reaction. Constrictive Pericarditis occurs when the pericardial layers become stiff and stick together. This leads to swelling on the hands and feet as well as atrial fibrillation. Symptoms of pericarditis include shortness of breath while lying down and abdominal swelling. There may be low-grade fever and overall fatigue. Dry cough is noticed in some patients suffering from pericarditis. Chest pain with pericarditis is usually stabbing and felt in the center of the heart.

Diagnosis of pericarditis is done with ECG, MRI and chest x-rays. Complete Blood Count (CBC) and other blood tests to measure cardiac enzymes aid in diagnosing pericarditis. Rest is recommended and in severe cases, hospitalization may be necessary. NSAIDS are prescribed to decrease the pain and inflammation. Any infection is treated with antibiotics. If atrial fibrillation is noticed, anti-arrhythmics are prescribed. Somtimes costicosteroids are used for treating inflammation. Diuretics aid in removing excess fluid. The pericardial fluid may be drained to aid better functioning of the heart.

Pneumonectomy

Pneumonectomy is a surgical removal of the lung. This is done on patients suffering from lung cancer, COPD and emphysema. When a person is suffering from lung cancer, it has to be ascertained if the cancer has not spread. CT scan and bone scan can help. When the patient has a tumor near the lung center, pneumonectomy is done when there is no other option. In a simple pneumonectomy surgery, only the affected lung is removed. In extrapleural pneumonectomy, a part of the pericardium and parietal pleura is also removed.
