TONSILLITISTONSILLITIS
Tonsillitis is an Tonsillitis is an infection (usually infection (usually viral) of the tonsilsviral) of the tonsils
If a child has many If a child has many infections, the infections, the tonsils are tonsils are surgically removedsurgically removed
TONSILLITISTONSILLITIS
It is believed the It is believed the tonsils help tonsils help prevent bacteria prevent bacteria and other and other pathogens from pathogens from entering the body entering the body – therefore a – therefore a removal may removal may increase the increase the number of number of illnesses later in illnesses later in lifelife

"Pneumonia" encompasses many different diseases that involve infection or inflammation of the lungs. Pneumonia is caused by a variety of agents such as bacteria, viruses, and mycoplasmas, among others. Pneumonia remains an important cause of morbidity and mortality in the United States; in 1996 there were an estimated 4.8 million cases of pneumonia.Pneumonia affects the lungs in two ways. Lobar pneumonia affects a lobe of the lungs, and bronchial pneumonia can affect patches throughout both lungs.
Lobular pneumoniaLobular pneumonia
Lobular Lobular pneumonia pneumonia affects a lobe affects a lobe of the lungs of the lungs (see x-ray), (see x-ray), and bronchial and bronchial pneumonia pneumonia can affect can affect patches patches throughout throughout both lungs.both lungs.

PLEURISYPLEURISY The The pleurapleura is a sac is a sac
surrounding the lungs. It surrounding the lungs. It consists of two layers, one consists of two layers, one covering the lung covering the lung ((visceralvisceral), while the other ), while the other covers the inside of the covers the inside of the chest wall or rib cage chest wall or rib cage ((parietalparietal). Between the ). Between the two layers is a space in two layers is a space in which a small amount of which a small amount of fluid circulates to lubricate fluid circulates to lubricate the two surfaces as they the two surfaces as they slide over one another slide over one another during breathing.during breathing.
PLEURISYPLEURISY Pleurisy refers to Pleurisy refers to

EMPHYSEMAEMPHYSEMA A chronic A chronic
respiratory respiratory disorderdisorder
The alveolar walls The alveolar walls break down & lose break down & lose their elasticitytheir elasticity
Surface area is Surface area is greatly reduced – greatly reduced – breathing is breathing is difficultdifficult
EMPHYSEMAEMPHYSEMA
CAUSE: usually CAUSE: usually from many years from many years of smokingof smoking
Effects are Effects are permanent and permanent and incurableincurable
EMPHYSEMA - EMPHYSEMA - treatmentstreatments Low-flow oxygen Low-flow oxygen
tank – delivers a tank – delivers a higher oxygen higher oxygen concentrationconcentration
Lung volume Lung volume reduction surgery reduction surgery (LVR) – removal of (LVR) – removal of damaged tissue damaged tissue to let healthy to let healthy tissue work more tissue work more efficientlyefficiently
CYSTIC FIBROSISCYSTIC FIBROSIS Genetic conditionGenetic condition An abnormal An abnormal
gene causes the gene causes the cells lining the cells lining the alveoli to secrete alveoli to secrete a thick, sticky a thick, sticky mucusmucus
Mucus attracts Mucus attracts bacteria and bacteria and numerous numerous infections resultinfections result
CYSTIC FIBROSIS - CYSTIC FIBROSIS - treatmentstreatments
There is no cure – There is no cure – life expectancy is life expectancy is usually low – early usually low – early 30s30s
Medicines are Medicines are used to thin the used to thin the mucusmucus
Antibiotics are Antibiotics are given for given for infectionsinfections
CYSTIC FIBROSIS CYSTIC FIBROSIS
New treatments New treatments include gene include gene therapytherapy
An inhaler is used An inhaler is used to spray healthy to spray healthy versions of the versions of the abnormal gene – abnormal gene – the healthy genes the healthy genes can then make can then make proper mucusproper mucus
