Asthma in children - ANSWER-* affects boys more
* severity is influenced by socioeconomic status, access to
care, lack of heatlh insurance, genetics, and air pollution.
* Vitamin D defficiency can play a role in severity and suppress
the Th2 mediated immune response
* path is the same as in adults
* exacerbations are usually triggered by viral infections such as
RSV
* runny nose, fever, faint breath sounds, and sometimes barrel
chest
* in severe cases the child may have retractions, nasal flaring,
and accessory mucsle use
Primary TB - ANSWER-* macorphages ingulf the myobacterium
and form a granuloma of tubercle, this triggers the
inflammation cascade and causes the center of the lesion to
necrose and calcify
* usually these ppl are asymptomatic and does not cause active
infection Secondary TB - ANSWER-* the tubercle is active and
spead other place in the lungs
* ppl experience symptoms= fever, hemoptysis, pleural
effusion, wasting, and weight loss
, * lesions occur in the apices
* infection can spread and myobacterium can spread to other
parts of the body such via the blood and lymphatic system
Pulmonary Embolus - ANSWER-* partial or complete occlusion
of the blood flow to the pulmonary artery
* most commonly from a proximal DVT in the lower extremities
* may be cause from fragments, foreign body, an air bubble, fat
embolus from a fracture, and amniotic fluid
* risk factor= any risk factor for DVT or hypercoagulable state *
when embolus lodges it triggers serotonin, histamine,
catcholomines, angiotensin II inflammation mediators, and
toxic oxygen free radicals
* can cause increased pulmonary arterial pressure that leads to
right ventricular dilation, and increased afterflow
* the decreased blood flow causes a V/Q mismatch and
decreases surfactant production
* the decreased surfactant production causes atelectasis and
hypoxemia and can also cause lung infarction, decrease
cardiac output, shock and death. * Saddle Embolus= sits on
the bifurcation of the pulmonary artery and can block all blood
flow to the lungs
CM= vague but are syncope, cough, dyspnea, tachycardia, or
unexplained anxiety, hemoptysis may also be present.
* diagnosis can be hard because symptoms are vague so pay
attention to risk factors in individuals that display these
symptoms
Lung Cancer - ANSWER-* usually malignant
