At sqadia.com, Dr. Saima Mushtaq aims to elaborate the medical lecture lung abscess in her medical video lecture. Initially, she defines the term lung abscess and then explains what causes this disease, how development of lung abscess takes place. After that, pathogens causing lung abscess are discussed. Furthermore, various techniques are highlighted through which diagnosis can be carried out. To conclude, our medical specialist elaborates the associated complication, treatment and prevention.
Etiology and Pathogenesis
Lung Abscess represents necrosis and cavitation of the lung following microbial infection. There are two types of lung abscess i.e. primary lung abscesses and secondary lung abscess. Primary lung abscesses arise from aspiration while secondary lung abscesses arise due to underlying condition. Then pathogenesis of primary lung abscesses is discussed. pathogenesis of Secondary Lung Abscesses depends on predisposing factors.
Pathology and Microbiology
Most common locations of primary lung abscesses are posterior upper lobes and superior lower lobes. The frequency of nonspecific lung abscess is 40%. In putrid lung abscess foul-smelling breath and sputum is seen. After that, Dr. Saima Mushtaq comprehensively explains the pathogens causing lung abscess. Clinical signs of lung abscess are sputum production, cavernous breath sounds on lung auscultation, discolored phlegm.
Chest imaging or radiograph, CT scan, transtracheal aspiration, empirical therapy, and sputum collection for gram staining are some of the techniques used for the diagnosis of primary lung abscess. Diagnosis of secondary lung abscess can be accomplished through sputum and blood cultures, serologic studies, and CT-guided percutaneous needle aspiration.
Treatment and Prevention
In this section of the lecture, our medical specialist illuminates the treatment modalities which include antibiotics course and surgery. For the treatment of secondary lung abscess antibiotic coverage for pathogen is discussed. Complications are also highlighted. Prevention strategy is the mitigation of underlying risk factors.
