A systematic review of delay in the diagnosis and treatment of tuberculosis

Patient and health system delays in the diagnosisPatient and health system delays in the diagnosis and treatment of tuberculosis in Southern Taiwan.

Int J Tuberc Lung Dis. 2005 Sep;9(9):1006-12.Int J Tuberc Lung Dis. 2005 Sep;9(9):1006 12.

CONCLUSION: Patient delay was substantially shorter thanPatient delay was substantially shorter than

health system delay.

To reduce health system delay clinics needTo reduce health system delay, clinics need to be involved and the referral mechanism must be strengthened.

Physicians should maintain high alert for TB and perform prompt sputum smear examinations

In inflammatory conditions in which fibrin is deposited in tissues, PAI-1 appears to play a significant role in the progression to fibrosis (pathological formation of connective tissue : tissue remodeling
