Q

CF diet

A

High calorie and high fat with pancreatic enzyme supplementation for every meal. Patients with cystic fibrosis (CF) have an increased energy requirement due to the chronic inflammation and infection associated with their disease. The UK Cystic Fibrosis Trust’s nutritional guidelines recommend a high-energy, high-fat diet to meet these needs. Additionally, CF patients often suffer from pancreatic insufficiency which leads to malabsorption of nutrients, especially fat. Therefore, they require pancreatic enzyme replacement therapy (PERT) with every meal and snack to aid digestion and absorption of nutrients.

44
2ndary pneumothorax
COPD patients, particularly those with advanced disease, may not present with overt signs of distress even when their secondary pneumothorax is worsening. Therefore, inpatient monitoring is warranted to detect any changes in clinical status that could require escalation of care, such as the need for a chest drain or even more invasive interventions.

Its presentation can often be with constitutional symptoms such as weight loss, lethargy and low-grade fever, though in advanced disease it can progress to haemoptysis and renal failure.

Exercise-Induced Bronchoconstriction: LTRAs are also used in patients with exercise-induced bronchoconstriction (EIB), reducing symptoms by preventing the leukotriene-mediated bronchoconstriction.
78
Serum ACE is used in diagnosis of
Sarcoidosis
79
Mucosal oedema and mucus plugging
Chronic bronchitis and asthma
80
Emphysema pathogenesis
destruction of alveolar walls secondary to proteinases. This is the fundamental pathophysiological mechanism underlying emphysema. The condition primarily results from an imbalance between proteases (particularly neutrophil elastase) and antiproteases (mainly alpha-1 antitrypsin) in the lung tissue. This imbalance leads to the breakdown of elastin and other structural proteins in the alveolar walls, causing permanent destruction of the air spaces distal to the terminal bronchioles. The result is decreased elastic recoil, air trapping, and reduced gas exchange surface area.
81
****** are commonly used in various industries, including automotive, paint manufacturing, and furniture production. They are known to be potent respiratory sensitizers and have been identified as one of the most common causes of occupational asthma.
Isocyanates

Contra indications to CF Lung transplant
absolute contraindications include systemic sepsis and failure to identify an appropriate antibiotic regimen for treatment. Chronic infection with Burkholderia cepacia is an important CF-specific contraindication to lung transplantation
89
Kartagners syndrome is not associated with
Malabsorption, as ciliary dyskinesia is restricted to respiratory endothelium rather than gut
90
Bilateral hilar lymphadenopathy
Bilateral hilar lymphadenopathy The most common causes of bilateral hilar lymphadenopathy are sarcoidosis and tuberculosis. Other causes include: lymphoma/other malignancy pneumoconiosis e.g. berylliosis fungi e.g. histoplasmosis, coccidioidomycosis
91
Silica exposure has been found to be causing increased risk of
TB
92
Crocidolite (blue) asbestos is the most dangerous form
93
A normal FEV1/FVC ratio and total lung capacity with low diffusing capacity are indicative of conditions that compromise effective gas exchange while ventilation remains preserved. These include disorders affecting pulmonary perfusion like chronic pulmonary embolism and alveolar gas exchange issues such as thickening alveolar walls seen in pulmonary fibrosis.
94
LTOT should be offered to patients with
a pO2 of < 7.3 kPa or to those with a pO2 of 7.3 - 8 kPa and one of the following: secondary polycythaemia nocturnal hypoxaemia peripheral oedema pulmonary hypertension
95
Patients typically present with a cough, shortness of breath, fever and malaise. Symptoms can be present for weeks or months. There is often a history of non-response to antibiotics. Haemoptysis is rare. Clinical examination is often normal but inspiratory crackles can be heard. Wheeze and clubbing are rare. Bloods show a leukocytosis and an elevated ESR and CRP. Imaging typically shows bilateral patchy or diffuse consolidative or ground glass opacities. Lung function tests are most commonly restrictive but can be obstructive or normal. The transfer factor is reduced. Treatment is watch and wait if mild or high dose oral steroids if severe.
COP Cryptogenic organizing pneumonia (COP) is a diffuse interstitial lung disease that affects the distal bronchioles, respiratory bronchioles, alveolar ducts and alveolar walls
