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
Asthma - ANSWER-* reactive airway disease triggered by
allergy
* mortality is highest in adult females, african americans, and
ppl over 65
,* significant genetic component
* exposure to allergens during childhood increase risk
* Patho- IgE mediated reaction
-airway narrows
- dyspnea and expiratory wheezes
- cellulars levels change- bronchial smooth muscle
hypertrophy, goblet cell hyperplasia, thickening and hylinizing
of basement membrane and proliferation of eosinophils and
mucous plug
- this leads to air trapping and causes decreased alveolar
ventilation
- hyperventilation occurs and lungs become hyperexpanded
-CO2 retention and respiratory acidosis occurs
- respiratory acidosis is a precursor to respiratory failure
* persons are asymptomatic and PFT is normal
* symptoms during attack= chest constriction, expiratory
wheezing, prolonged expiration, tachycardia, and tachypnea
* severe attacks= use of accesory muscles and both inspiratory
and expiratory wheezing, a silent chest, and PaO2 less than or
equal to 70mmHg
, Pneumonia - ANSWER-2 types= community acquired and
hospital acquired * inmmation or process that causes a build
up of inflammartor exudate in the alveolar sacs
* can be cause by bacterial, viral, fungal, ro aspiration
* elderly have a highest mortality
* Risk Factors= advanced age, suppressed immune system,
underlying lung disease, alcohol abuse, decreased level of
consiousness, chest trauma, dysphagia, smoking, intubation,
malnutrition, immobility, cardiac and liver disease, and
residing in a nursing home
Community Acquired Pneumonia - ANSWER-* outside hospital
* step pneumoniae- is the most common cause of PNA
* staph aureus- arrizes from influenza or viral pneumonia
* strep pyogens- from viral infection such as influenza or
measels
* Klebsiella pneumoniae- common in hospitalized debilitated
pts, diabetes, or alcoholics, high mortality rate in elderly
* haemophilus influenza- common in infants and children and
COPD adults
Hospital Acquired Pneumonia - ANSWER-* 48 hours after
being admitted * common cause= gram negative bacteria
such as Klebsiella Pseudomonas aeruginosa and E-Coli.
