Inc prevalence in 1985 post HIV outbreak as HIV weakness immune system

30
Q

TB cause

A

Spread through droplets
Bacteria
Contagious, but not easy to catch
2 weeks of treatment= no longer contagious

31
Q

A

HIV/AIDS
Diabetes
Severe kidney disease
Very young or advanced age
Some drugs with treat rheumatoid diseases

32
Q

TB presentation

A

Latent TB- have Tb but bacteria in body are inactive and cause no symptoms, treatment important to prevent it becoming active
Active TB- show symptoms, can spread to others, can occur weeks or years after TB bacteria infection
Soughing for 3 or more weeks
Coughing up blood or mucus
Night sweats
Loss of appetite
Chest P especially when coughing or breathing

33
Q

TB prognosis

A

Any TB strains are resistant to drugs
Multiple medication needed to be taken for months to get rid of infection and prevent AB resistance

34
Q

Emphysema

A

Lung condition causing shortness of breath
Alveoli damaged, over time inner walls of air sacs weaken and rupture- creating large air spaces instead of small ones
Reduces SA of lungs  reduced oxygen to bloodstream
During exhalation, damaged alveoli don’t work properly and old air is trapped, leaving no room for oxygen-rich air to enter

35
Q

Emphysema cause

A

Long-term exposure to airborne irritants e.g., tobacco smoke, air pollution, chemical fumes and dust

36
Q

Emphysema risks

A

Smoking
Age- 40-60
Exposure to second-hand smoke
Occupational exposure to fumes or dust

37
Q

Emphysema presentation

A

Can have it many years without noticing
Main symptom is shortness of breath, so doesn’t become a problem until it interferes with daily life
Causes shortness of breath whilst at rest

38
Q

Emphysema prognosis

A

Complications include- collapsed lungs, heart problems, large holes in lungs (bullae)

39
Q

Asthma

A

Airways narrow and swell and may produce extra mucus
Minor-major

40
Q

Asthma cause

A

Not clear, thought to be due to combination of enviro and genetic factors
Triggers:
1. Airborne allergens- e.g., pollen, dust mites
2. Respiratory infections
3. Physical activity
4. Cold air
5. Air pollutants
6. Strong emotion/stress

41
Q

Asthma population

A

Female= inc risk
Younger population
1/12 adults- late onset asthma

On the inc due to pollution

42
Q

Asthma risks

A

Blood relative with asthma
Overweight
Smoker
Exposure to second hand smoke
Exposure to exhaust fumes/occupational triggers

43
Q

Asthma presentation

A

Variable
May have infrequent asthma attacks
Shortness of breath
Chest tightness or P
Wheezing when exhaling, common in children
Trouble sleeping caused by shortness if breath
Worsening signs- more frequent and bothersome, inc difficulty breathing, need to use quick-relief inhaler

44
Q

Asthma flare ups in certain situations

A

Exercise induced- may be worsened by cold or dry air
Occupational asthma- triggered by workplace irritants
Allergy induced asthma- triggered by airborne substances (pollen, cold spores)

45
Q

Asthma prognosis

A

Can be minor or major
Can’t be cured but symptoms can be controlled
Important to work with doctor to track signs and symptoms and adjust to changes

Metered dosed
Dry powder inhaler
Soft mist inhaler
-inhale corticosteroids- reduce inflammation in lungs, prevent attacks
-short-acting bronchodilators- use during attack

46
Q

Cystic fibrosis

A

Inherited disorder that causes severe damage to lungs, digestive system and other organs
Affects cells that produce mucus, sweat and digestive juices- usually thin and slippery, people with CF have a defective gene causing secretions to be sticky and thick
Instead of acting as a lubricant it plugs up tubes, ducts and passageways especially in lungs and pancreas

47
Q

Cystic fibrosis cause

A

Mutation in a gene- cystic fibrosis transmembrane conductance regulator (CFTR) gene- changes protein that regulates movement of salts in and out of cells
Results in sticky mucus in respiratory, digestive and reproductive systems as well as inc salt in sweat
Children need to inherit one copy of the gene from each parent in order to have disease
If children develop one copy they won’t develop CF, however they will be carriers and could pass it one to their children

48
Q

Cystic fibrosis population

A

Northern Europeans

49
Q

Cystic fibrosis risks

A

Family Hx
Most common in Northern European ancestry

50
Q

Cystic fibrosis presentation

A

Variable
May not experience symptoms until teenage years or adulthood
Tend to have higher salt in sweat, parents can tell when kissing their children
Respiratory- persistent cough that produces thick mucus, wheezing, exercise intolerance, repeated lung infections, recurrent sinusitis
Digestive- thick mucus can block rubes that carry digestive enzymes from pancreas to small intestines- without these unable to absorb nutrients from food resulting in foul smelling stools, poor weight gain and growth, intestinal blocks particularly in new-borns, chronic or severe constipation

51
Q

Cystic fibrosis prognosis

A

Requires progressive treatment/daily care, but usually able to attend school or work
Improvements in screening treatments mean people with CF now may live into mid-late 30s or 40s, some into 50s
Genetic screening

52
Q

Lung cancer

A

Leading cause of cancer deaths worldwide
Types:
1. Small cell- almost exclusively in heavy smokers
2. Non-small cell- umbrella term for several types, includes squamous cell carcinoma, adenocarcinoma and large cell carcinoma

53
Q

Lung cancer cause

A

Smoking- both smokers and those exposed to second hand
o Damage to cells which line lungs
o Inhalation of carcinogens changes kung tissue immediately
Other than smoking, no clear cause

54
Q

Lung cancer population

A

65+

55
Q

Lung cancer risks

A

Smoking
Exposure to second hand
Previous radiation therapy

56
Q

Lung cancer presentation

A

Rarely symptoms in early stages
New cough that doesn’t go away
Coughing up blood

Bone P
Headache

57
Q

Lung cancer prognosis

A

Many complications- coughing up blood, shortness of breath, P, fluid in chest, cancer that spreads
2/5 live for a year after diagnosis
1/10 live for ten years

58
Q

Pneumothorax

A

Collapsed lung
Occurs when air leaks into space between lung and chest wall
Air pushes on outside of lung and it collapses

59
Q

Pneumothorax cause

A

Chest injury- blunt or penetrating
Lung disease- damage inc likelihood, e.g., CF
Ruptured air blisters- develop at top of lung, occasionally burst allowing air to leak into space that surrounds lungs
Mechanical ventilation- severe type, imbalance of air pressure created within chest by ventilator

60
Q

Pneumothorax population

A

Tall, thin people
Smokers

61
Q

Pneumothorax risks

A

Smoking
Genetics
Previous pneumothorax

62
Q

Pneumothorax presentation

A

Sudden chest P
Shortness of breath
Severity depends on how much lung is collapsed

63
Q

Pneumothorax prognosis

A

Insert needle or chest tube between ribs to remove excess air
Can heal on its own

64
