'red flags' for lung cancer

-
Lung cancer is one of the most common malignancies worldwide, but has one of the poorest outcomes as 2/3rds of patients present late with the disease. Given this it is important to be vigilant of the possibility of lung cancer in patients. Patients with lung cancer may present with respiratory symptoms, with worsening chronic disease such as COPD, with symptoms suggestive of malignancy without symptoms specific to the respiratory system, and occasionally with other symptoms which are neither respiratory or point to a malignancy.


NICE guidelines suggests that an urgent chest x ray (within 1 week) should be considered for the following symptoms:

  • Haemoptysis
  • Persistent (+3 weeks) cough
  • Persistent shortness of breath
  • Persistent chest signs
  • Persistent hoarseness
  • Persistent weight loss
  • Persistent clubbing
  • Persistent cervical lymphadenopathy
  • Persistent chest or shoulder pain (think of pancoast tumours)
  • Persistent signs or symptoms suggesting metastases such as bone pain, skin changes, liver changes, or neurological changes. 


A normal chest X-ray does not always rule out the possibility of malignancy

In addition urgent referral to the lung cancer multidisciplinary team should be made if a patient presents with:
  • Smoker over 50 presenting with new haemoptysis
  • Signs and symptoms of superior vena caval obstruction
  • Stridor

Pleural effusion

Definition Pleural effusion is a collection of fluid in the pleural space between the visceral pleura surounding the lungs and the parietal pleural attatched to the throacic wall. Demographics Pleural effusions are relatively common, but it is a manifestation of other underlying diseases. The prevalence and incidence of pleural effusions is therefore dependent on it's cause. Pathophysiology/causes Pleural fluid is usually filtered from the parietal pleura into the pleural space, due to hydrostatic pressure from the capillaries, negative pressure in the pleural space and pleural oncotic pressure. The visceral pleura is perfused by the pulmonary system which has a lower pressure, and fluid in the pleural space is therefore drawn back in through the visceral pleura due to the higher oncotic pressure in plasma. Some of this fluid is then drained by the lymphatic system.

Diabetic Ketoacidosis (Adults)

-

Definition : A major life threatening metabolic condition occurring in diabetic patients leading to hyperglycaemia , ketoacidosis , dehydration and ketonuria . Pathophysiology:  The lack of insulin primarily leads to hyperglycaemia and ketonaemia:  Insulin insufficiency leads to reduced uptake of glucose into cells and increased blood concentration of glucose.  As glucose are not taken into cells, alternative sources of energy are used.  Most cells break down fatty acids instead of glucose which forms ketones. Ketone levels therefore reflects the glucose deficit in cells.  Lack of insulin also leads to an increase in opposing hormones which lead to increased glycogenolysis, gluconeogenesis and lipolysis.
