what is ARDS
In ARDS, the alveolar capillaries become more permeable, leading to fluid accumulation in the alveoli. This is non-cardiogenic pulmonary oedema. There are several underlying pathophysiological mechanisms that have been suggested including pro-inflammatory cytokines and chemokines, as well as neutrophilic infiltration. The commonest finding in ARDS is hypoxaemic respiratory failure. The commonest clinical presentation is acute-onset cyanosis, dyspnoea and tachypnoea.
ARDS has a mortality rate of 30–45% and has significant morbidity in the population that does survive. The American-European consensus conference has developed a number of criteria for recognising ARDS including: <1 week onset of a known risk factor, pulmonary oedema, non-cardiogenic, and pO2/FiO2 ratio <40 (a defining feature).

A 28-year-old Afro-Caribbean woman presents to the emergency department with shortness of breath, painful red lesions on her shins and pain in her ankle joints.
Vitals signs show a temperature of 38.4. A chest X-ray is ordered and shows bilateral hilar lymphadenopathy.
Which of the following is the most likely diagnosis?
This lady is presenting with acute sarcoidosis, also known as Lofgren’s syndrome. This is the combination of bilateral hilar lymphadenopathy, erythema nodosum, acute polyarthritis and fever. Sarcoidosis is also more common in those of Afro-Caribbean heritage
hF mamagement
Captopril, Bisoprolol and Pneumococcal vaccination
This is the correct answer. The patient has signs, symptoms and chest x-ray are consistent with left sided heart failure. Patients with chronic heart failure are managed with angiotensin converting enzyme inhibitors (ACEi) and beta blockers as first line management. ACE-i work on the renin angiotensin aldosterone axis to dilate blood vessels and decrease blood pressure. Beta blockers reduce the heart rate and improve the ejection fraction as the heart can fill more efficiently. Additionally, the pneumococcal vaccine is given to patients with chronic heart failure and those over the age of 65 to reduce the risk of developing a streptococcus pneumoniae pneumonia

The patient is presenting with shortness of breath but is saturating well at 15.0 kPa (not hypoxic - therefore by definition not in respiratory failure). Their pH and CO2 are however quite deranged - however in-keeping with the normal physiological response to breathing more quickly (blowing off more CO2 and as a result your carbonic anhydrase equation shifts and the patient becomes more alkalotic). The normal bicarbonate indicates that the cause of this alkalosis is respiratory in origin.
are the pneumococcal and influenza vaccines live

A 43-year-old gentleman is assessed in A&E. He presents with a one week history of shortness of breath, non-productive cough and fevers. He has a past medical history of HIV and says he had stopped taking his antiretroviral medication 6 months ago due to side-effects. On initial assessment, he appears unwell, tachypneic and has oxygen saturations of 90% on air.
His chest X-ray is as follows:
This patient has become short of breath and febrile on a background of uncontrolled HIV. It is likely that he is immunocompromised. He is hypoxic and his chest X-ray shows bilateral ground glass like opacification most prominent in the lung bases. This is highly suspicious for PCP and should be treated accordingly

This is correct. It is the definitive management of a patient with a curative adenocarcinoma (non-small cell lung cancer), patients must undergo pulmonary lung function tests prior to treatment with surgery

A 30 year old woman develops a five day history of a productive cough and high fever. She also has been short of breath progressively over the past few days.
Furthermore, she complains of painful blue fingers and toes over the past two days, which occur whenever she is outdoors and the temperature has dropped. Yet when indoors she has noticed they return to their normal colour.
What additional findings would you expect to see on examination?
Multiple erythematous papules with deeply erythematous borders
This is correct. The patient has signs of cold autoimmune haemolytic anaemia and a pneumonia. The pneumonia most commonly associated with this autoimmune condition is mycoplasma pneumonia. Mycoplasma pneumonia can also present with erythema multiforme
