Question 24

Determinants of health
Most at risk are the indigenous and immigration populations.
Males more then women
Higher rates in low socioeconomic groups, overcrowded living conditions, smoking and air pollution

Answer 24

Tuberculosis

Question 25

Etiology and pathophysiology: Infectious disease caused by Mycobacterium tuberculosis Spread via airborne droplets when infected person coughs, speaks, sneezes, sings Organisms are dispersed in a room and then inhaled (rare for infection after brief exposure) Inhaled bacilli pas into the bronchial system and implant on bronchioles or alveoli and multiply initially. Spreads via lymphatic system. Favorable environments for growth include the upper lobes of the lungs, kidneys, epiphyses of bone, cerebral cortex and adrenal glands. Tissue granuloma form which contains the bacteria then prevents replication and spread (Ghon complex is formed) Latent TB infections (LTBI) organisms persist for years with few ever developing TB

Answer 25

Tuberculosis

Question 26

Clinical manifestations early stages are usually free of symptoms Cough (hemoptysis is associated with advanced disease, dyspnea is unusual) May have chest pain characterized as dull or tight. Acute symptoms (flulike) High fever, chills, pleuritic pain, productive cough

Answer 26

Tuberculosis

Question 27

Miliary tuberculosis Pleural effusion and empyema Tuberculosis pneumonia Other organ involvement: CNS (meninges), Bone and joint tissue, kidneys adrenal glands, lymph nodes, genital tract

Answer 27

Tuberculosis complications

Question 28

large number of organisms travel through the bloodstream and spread to all organs

Answer 28

Miliary tuberculosis

Question 29

Caused by bacteria in pleural space. Inflammatory reaction with plural exudates of protein rich fluid. Can result from primary TB disease or reactivation of a latent infection. Empyema is not as common as pleural effusion but may occur from large number of tubercular organisms in the pleural space.

Answer 29

Pleural effusion and empyema

Question 30

Large amounts of bacilli discharging from granulomas into lung or lymph nodes. Clinical manifestations are similar to those of bacterial pneumonia.

Answer 30

Tuberculosis pneumonia

Question 31

Tuberculin skin testing Chest radiographic study Bacteriological studies QuantiFERON-TB (QFT)

Answer 31

Diagnostic studies for TB

Question 32

Intradermal administration of tuberculin Sensitivity remans for life and individual should not be tested again Response decreases in immune compromised Reactions > or equal to 5mm considered positive

Answer 32

Tuberculin skin testing

Question 33

Can not rely solely on x-ray to make diagnosis Upper lob infiltrates, cavity infiltrates and lymph node involvement suggest TB

Answer 33

Chest radiographic study

Question 34
