An exacerbation is defined as the increase in three or more key symptoms: cough, sputum volume and/or consistency, sputum purulence
, breathlessness and/or exercise intolerance, fatigue, and coughing up blood for at least 48 hours.
increased sputum volume, purulence
and dyspnoea, or two of these features, where one is increased sputum purulence
, should receive an antibiotic.
To diagnose the patients and grade the severity of acute exacerbation of COPD, clinical guidelines have included the, Winnipeg criteria  based on increased breathlessness, sputum volume and purulence
was noted within the medullary space, and marked osteolysis of the right condyle, ramus and coronoid process (Figure 2 A-B).
Local features include purulence
, erythema, induration, tenderness, or calor it may be accompanied by systemic indicators of infection such as fever or hypothermia, tachycardia, or tachypnea.
 COPD exacerbation was defined as the presence of at least two of the following criteria: the presence of dyspnea increased sputum production and increased sputum purulence
. Demographic data, complete blood count and biochemistry results, arterial blood gas measurements, radiological findings of the patients and patients who died in ICU were collected from the hospital's electronic record system and patient medical charts.
Clinical importance of purulence
in methicillin-resistant Stapylococcus aureus skin and soft tissue infections.
Repeat MRI performed prior to hospital discharge indicated near resolution of purulence
. A hearing screen was passed prior to discharge.
Purulent pericarditis is a rare subset of bacterial pericarditis that is characterized by gross or microscopic purulence
in the pericardium and most commonly develops from direct contiguous spread of an intrathoracic infection (such as pneumonia or mediastinitis) or intracardiac source and less commonly via hematogenous spread.
An exploratory laparotomy was performed revealing diffuse retroperitoneal purulence
, as well as an abscess rupture of the right kidney and a perforation of the colon at the base of the caecum.
There was no intraoperative evidence of necrotizing fasciitis, purulence
, or foul odour.
The patient developed purulence
at his incision site one month postoperatively requiring intra-washout with neurosurgery.
