A 54 years old previously well patient admitted with progressively worsening shortness of breath for 2 days duration. He had low grade fever for the same duration. There was no history of cough, wheezing or chest pain. He had facial and leg swelling. 4 days back he had taken medications from the local hospital for a back pain he developed after lifting a cupboard. What are the differential diagnoses?

There was a erythematous rash all over the body. Blood pressure was 180/100mmHg. There was no cardiomegaly or murmurs. Lungs had few basal crepirations and occasional wheezing. Abdomen was soft. In patients who are tachypnoeic, few lung signs can always be present. Correlate the degree of SOB with the lung signs. If the SOB is disproportionately severe compared to the signs, consider following differentials. Pulm

A 54 years old male patient, known to have GORD for many years presented with burning chest pain. The pain was persistent. There was no radiation to the arm. He had sweating and nausea. There was no shortness of breath. He is a smoker. He has never tested his blood sugar or lipid profile. On examination, the patient is ill and sweaty. The pulse rate is 92/min. Blood pressure is 150/100mmHg. There are no murmurs. Lungs are clear. What are you going to do? This is a very common clinical scenario.
