Can a Ranke complex reactivate?
A Ghons complex retains viable bacteria, making them sources of long-term infection, which may reactivate and trigger secondary tuberculosis later in life.
What is Ghon complex in TB?
The Ghon complex is a non-pathognomonic radiographic finding on a chest x-ray that is significant for pulmonary infection of tuberculosis. The location of the Ghon’s focus is usually subpleural and predominantly in the upper part of the lower lobe and lower part of the middle or upper lobe.
What is Ranke complex?
Ranke complex is seen in ‘healed’ primary pulmonary tuberculosis and is a later manifestation of the Ghon complex. It consists of two components: a Ghon lesion that has undergone calcification. an ipsilateral calcified mediastinal node.
What are the symptoms of the people suffering from latent tuberculosis?
The Difference between Latent TB Infection (LTBI) and TB Disease
- a bad cough that lasts 3 weeks or longer.
- pain in the chest.
- coughing up blood or sputum.
- weakness or fatigue.
- weight loss.
- no appetite.
- chills.
- fever.
What is secondary TB?
Secondary pulmonary TB (reactivation) is characterized by a focus of infection and granuloma formation usually in the apex of the lung. The small granulomas (tubercles) eventually coalesce to form larger areas of consolidation with central caseating necrosis. Regional lymph nodes contain caseating granulomas.
What is the difference between primary and secondary infections?
While a primary infection can practically be viewed as the root cause of an individual’s current health problem, a secondary infection is a sequela or complication of that root cause. For example, an infection due to a burn or penetrating trauma (the root cause) is a secondary infection.
Is Primary Complex and tuberculosis the same?
The most common form of pediatric TB, the classical primary complex consists of a focal parenchymal lesion typically in mid-lower zones with enlarged draining hilar/paratracheal node. Other presentations of primary TB include miliary TB[7], exudative pleuritis and tracheo-bronchial TB[8,9].
