Lung abscess is a type of liquefactive necrosis of the lung tissue and formation of cavities (more than 2 cm) [1] containing necrotic debris or fluid caused by microbial infection. This pus -filled cavity is often caused by aspiration, which may occur during anesthesia, sedation, or unconsciousness from injury.
A parapneumonic effusion is a type of pleural effusion (accumulation of fluid in the pleural cavity) that arises as a result of a pneumonia, lung abscess, or bronchiectasis. [1] There are three types of parapneumonic effusions: uncomplicated effusions, complicated effusions, and empyema. Uncomplicated effusions generally respond well to ...
Many of these infections are less serious, but the Centers for Disease Control and Prevention (CDC) estimate that there are 80,461 invasive MRSA infections and 11,285 deaths due to MRSA annually. [109] In 2003, the cost for a hospitalization due to MRSA infection was US$92,363; a hospital stay for MSSA was $52,791. [89]
First-line treatment for serious invasive infections due to MRSA is currently glycopeptide antibiotics (vancomycin and teicoplanin). A number of problems with these antibiotics occur, such as the need for intravenous administration (no oral preparation is available), toxicity, and the need to monitor drug levels regularly by blood tests.
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [1] [2] [3] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Over the past six months, emergency rooms have discharged an increasing number of patients with a Mycoplasma pneumoniae diagnosis, which is typically associated with "walking pneumonia," or acute ...
Lung abscesses can usually be seen with a chest X-ray but frequently require a chest CT scan to confirm the diagnosis. [140] Abscesses typically occur in aspiration pneumonia, and often contain several types of bacteria. Long-term antibiotics are usually adequate to treat a lung abscess, but sometimes the abscess must be drained by a surgeon or ...
Pyaemia (or pyemia) is a type of sepsis that leads to widespread abscesses of a metastatic nature. [1] It is usually caused by the staphylococcus bacteria by pus-forming organisms in the blood. Apart from the distinctive abscesses, pyaemia exhibits the same symptoms as other forms of septicaemia.
