Pneumonia
Acute inflammation of lung (lowerrespiratory tract) caused by
microorganism, comes with fever,focal chest symptoms, shadowingon CXR
Leading cause of death until 1936Discovery of sulfa drugs and
penicillin

Classification
Community Acquired Pneumonia
Occur within 48 hrs of admission or inpatients who havent been hospitalized in thelast 2 wks
Strep pneumonia, mycoplasma pneumonia,influenza A, Haemophilus influenza, and
Legionella are more common pathogens Patients with chronic diseases are more prone
to Klebsiella and other gram negativeorganisms
Highest incidence in winter
Smoking important risk factor

Types of Pneumonia
Hospital-acquired pneumonia (HAP) (Nasocomial Infection)
Develops 2 or more days after admission
Gram negative bacilli (Klebsiella, Pseudomonas, E coli,Proteus) or Staphylococcus are more common pathogens
Aspiration around an ETT/reduced consciousness ordifficulty swallowing allows pathogens in the oropharynx tocolonize the lungs
Ventilator-associated pneumonia (VAP): in patients onventilators
Aspiation: follows aspiration of gastric contents
Immunosuppression: chemotherapy/bone marrowtransplant/HIV patients susceptible to fungi and viralinfections as well as other pathogen
Highest mortality rate of nosocomial infections

8/12/2019 Pneumonia (LECTURE3)
10/50
28/10/2009 10
Pathophysiology:
Pneumococcal Pneumonia
Congestion from outpouring of
fluid into alveoli
Microorganisms multiply and spread
infection, interfering with lung
function
8/12/2019 Pneumonia (LECTURE3)
11/50
28/10/2009 11
Pathophysiology:
Pneumococcal Pneumonia
Red hepatization
Massive dilation of capillaries
Alveoli fill with organisms,
neutrophils, RBCs, and fibrin
Causes lungs to appear red and
granular, similar to liver

What is tuberculosis (TB)?
Disease caused by bacteria calledMycobacter ium tuberculosis
Chronic bacterial infection
Was once the leading cause of death in US
The number of cases declined in the 1940swhen drugs were developed to treat TB
TB is still a problem worldwide
8 million people develop TB yearly
3 million die

How is TB spread?
Through the air from person to
person by coughing
Usually attacks lungs
Two stages
Latent TB asymptomatic and not contagious
can take medication to prevent developmentof disease
Active TB Disease May spread to others
May have abnormal chest x-ray
Usually have positive skin test

Symptoms of TB
Chills
Fever
Weakness or fatigue
Sweating while sleeping, Night sweats
Cough that lasts longer than 2 weeks
Pain in chest
Coughing up blood or sputum

Risk Factors
Close contact with someone who is infectedwith TB
Traveling to a country where TB is common
Foreign-born individuals and minoritieshave a higher incidence of developing TB
2002: 50% of US cases were in foreign-born individuals.
2002: 80% of all US TB cases were inethnic and racial minorities.

Multi-drug resistant TB (MDR TB)
Bacteria become resistant to antibiotics
Arose from improper use of antibiotics in thetreatment of TB
Treatment of one case can cost up to $1.3 million
45 states and Washington, DC have confirmed casesof MDR TB
Treatment is difficult and costly
Can develop from not taking proper course of
antibiotics for TBMDR TB can be spread by an infected person

How to protect yourself
BCG vaccine for TB is given in many countries
Not recommended for healthcare workers
unless a high percentage of patients areinfected with MDR TB
PPD test if exposure is suspected
USE proper PPE when in contact with patientswho may have TB

PPD Skin Test Procedure
Intradermal administration of PPD

10 mm or > area of induration
Consider positive and must be referred
