Thanks, Subodha Sugandika for your comprehensive answer. I will just add what's missing in red and will strikethrough  what is not that relevant. Microvascular complications of diabetes are diabetic nephropathy, diabetic retinopathy, and diabetic neuropathy.  1) Questions to ask from the patient:  Nephropathy: do u have a history of frothy urine?

But if a patient comes with pleural effusion with no evidence of an infection, that effusion is considered malignant unless proven otherwise. The first investigation in any pleural effusion is a chest Xray. It will confirm the diagnosis There will be aetiological clues like Pneumonic patch Malignant lesion Rib erosions Infarctions Nowadays, an ultrasound scan of the chest is done routinely in all patients with effusions. USS can sometimes visualize consolidations, masses and pleural diseases that might not be apparent on the Xrays. When a malignancy is suspected or the cause is not evident in other investigation modalities, CT becomes the most useful investigation. The most important investigation in any pleural effusion is the pleural fluid aspiration. You all have to know the technique of doing it. But, now the blind approach is no longer recommended and it alwa...

Look for associated conditions 6. Look for comorbid conditions 7. Look for drug-related side effects Remember this golden rule of physical examination. UNLESS YOU LOOK FOR A SIGN, YOU WILL NEVER SEE IT! Doing a thorough examination is a daunting task. Do not get depressed after reading this. I’m just trying to stimulate you. For your exam purposes telling 3-4 positives and negatives will be adequate. But, becoming a good clinician is not so easy. As an example let's see what we should look for in the general examination to find the aetiology (Only the aetiology!) of a pleural effusion. Please do not forget to read the part in red ! 1. Acute infection Fever Specific signs of some infections Melioidosis - Arthritis Atypical pneumonia - Skin rashes like erythemi...
