Q

What are the 3 causes of Rhinitis

A

Immune compromise - leading to viral/bacterial/fungal infections i.e due to emotional stress medications diet etc

Allergic Rhinitis - true allergic response to the likes of pollen. We create antibodies in response to an allergic reaction, these antibodies are called IgE (Immunoglobin) which stimulates mast cells to secrete Histamine

Non Allergic Rhinitis - associated with environment, lifestyle diet drugs such as NSAID’s, stress

What is the Pathophysiology of nasal polyps
Chronic inflammation causes the blood vessels in the lining of the nose to become more permable allowing water to accumulate in the cells. Over time, gravity pulls on the waterlogged cells and they can become polyps

50
What is the key chemical inflammatory mediator in Asthma and what do they do.
Leukotrienes which are bronchoconstrictors
51
Give 4 reasons why the prevalence of Asthma is increasing
Weaning to early Sterile environments Inherited dysbiosis Food additives Leaky gut Nutritional deficiencies i.e C D E And magnesium
52
What is Extrinsic (or atopic) Asthma
Typically effects children, immunologically mediated with an increase in IgE antibodies. Brought on due to exposure of pollen, dust and animal dander
53
What is Intrinsic Asthma

54
What are the signs and symptoms of Asthma
Recurrent episodes of breathlessness and chest tightness Wheezing on exhaling Nocturnal coughing (occasionally with a thick yellow sputum) Accessory muscles of ventilation are overused and cause aching in the back and upper neck
55
How do we diagnose Asthma
Based on signs/symptoms and history Spirometry - test breathing through a tube Peak flow meter
56
What are the pathological changes that happen in Asthma
Smooth muscle contracts and immune cells infiltrate the bronchioles as part of the inflammatory process which obstructs the airways.

58
What should you do if someone is having an asthma attack
Call for help: If patient cannot speak in sentences and has more than 25 breaths per minute encourage the patient to sit not lie down. use inhaler (usually blue bronchodilator every 30-60 seconds up to a maximum of 10 puffs

63
What is rapid shallow breathing called in medicine
Tachypnoea - Ta Kip Knee ah
64
What is auscultation
Listening to sounds from the lungs/heart and other organs using a stethoscope
65
Describe Bronchitis
Is an inflammation of the Bronchial tubes it can be acute or chronic
66
How do we develop bronchitis
Following a viral or bacterial infection from a cold or can be associated with environmental irritants.
67
When an irritant enters the airways xxxxx cells secrete mucus to flush it out. If xxxxx is overproduced the respiratory system struggles to clear it. This can xxxx xxxxx resistance and hence breathing difficulties
Goblet cells Mucus Increase airway resistance
68
Define COPD
COPD causes airflow limitation that is progressive and not fully reversible. The airflow limitation is due to airway and functional tissue damage. Is is a chronic inflammatory response of the lungs (usually from inhaled toxins)
69
Describe Chronic Bronchitis and key symptoms.
Inflammation and thickening of the bronchial lining with mucus hyper-secretion Key symptoms - Cough and wheezing
69
What are the 2 main pathologies that COPD make up. Describe each.
Emphysema - Dilation of alveolar sacs by destruction of the alveolar wall, leading to collapse Alveoli during expiration. Chronic Bronchitis - Inflammation and thickening of the bronchial lining with mucus hyper secretion
70
What are the main causes of COPD
90% smoking Exposure to lung irritants such as air pollution, industrial chemicals, dusts etc.
70
Describe the pathology Emphysema and key symptoms
Dilation of Alveolar sacs by destruction of alveolar wall. Leading to collapse of the alveoli during expiration. Breathlessness
70
What is the alternative name given to individuals with 1. Chronic Bronchitis 2. Emphysema
1. Blue bloater 2. Pink Puffer
71
What is the Pathophysiology of COPD
Smoking cigarettes and inhaling other irritants leads to high levels of oxidative stress in the respiratory tract. Oxidative stress damages the delicate cilia and promotes inflammation throughout the respiratory tract. Cells are damaged and scar. This, as well as excess mucus production leads to airflow obstruction
72
Signs and symptoms of COPD
Chronic cough with sputum, dyspnoea Prolonged expiration and wheeze Frequent infections Signs - Tachypnoea - breathlessness on exertion Patients may lean forward on a table to breath Pursed lips on breathing Flapping tremor Cyanosis - blue hands skin lips Barrel chest clubbed nails
73
What are the complications of COPD

74
What is pnoea
breathing

What is the allopathic treatment for COPD
Bronchodilators, smoking cessation, corticosteriods and Oxygen therapy
78
What is Pneumonia
An infection of the Alveoli and terminal Bronchioles, mostly bacterial. Associated with an infiltration of neutrophils with inflammation and Oedema
79
What are the signs and symptoms of Pneumonia
Cough and purulent sputum which maybe blood stained. Breathlessness fever and general malaise Signs - Tachypnoea, crepitations on auscultation
80
Define Pulmonary Fibrosis
Gradual replacement of the one-layer-thick epithelial cell lining in alveoli with fibrotic tissue.

Obesity, male gender, middle aged, smokers, alcohol, sedatives nasal obstruction (nasal polyps/Rhinitis)
86
What is the treatment for sleep apnoea
CPAP Nasal continuous positive airway pressure. this goes over the face when sleeping and helps to keep the pressure consistent in the airways. Lifestyle modification
87
What are the signs and symptoms of Sleep Apnoea
Loud snoring, day time sleepiness, morning headache, morning drowsiness, nocturnal chocking reduced libido.
88
How is Obstructive Sleep Apnoea diagnosed.
Polysomonography
89
Define a Pneumothorax
A Pneumothorax describes air accumulation within the pleural cavity causing all or part of the lung to collapse
90
How does air enter in a Pneumothorax and what could this be due too?
Air enters via a defect in the visceral or parietal pleura.
91
What do we base a Pneumothorax on?
A Pneumothorax can be simple (Heart remains central) or tension (unstable - progressive build up of air shifting the heart away)
92
What are the causes of a Pneumothorax
This can be due to a rib fracture, or spontaneous due to a cyst that has ruptured or associated to another disease such as TB or Cystic Fibrosis
93
What are the signs of a pneumothorax
Reduced breath sounds, decreased cardiac output
94
What are the symptoms of a pneumothroax
Dyspnoea and pleuritic (sharp) chest pain Cyanosis Loss of conciousness, coma
95
Define Pleurisy
It is an inflammation of the Pleura
96
What happens in Pleurisy
The pleural surfaces become coated with inflammatory materials and are hence roughened, producing the friction rub on auscultation.
97
What are the causes of Pleurisy
Tumour or infection e.g Pneumonia or Pneumothorax
98
Signs and symptoms of Pleurisy
Dysponea, sharp chest pain while breathing aggravated by inspiration, coughing, sneezing or moving around. May be relieved by shallow breathing. Dullness with percussion, friction rub on auscultation
