-Anterior STEMI Vs RV infraction:
How to differentiate between Anterior STEMI and isolated RV infarction (as both can shows ST elevation from V1-V3)?
-In patients with anterior left ventricular infarction, ST segment elevation is the lowest in lead V1, increasing in amplitude toward lead V5.
On the other hand, patients with an occluded RCA and RV infarction display the greatest amplitude of ST segment elevation in lead V1, which progressively decreases toward lead V5.

-Nephrotic syndrome is the combination of nephrotic-range proteinuria with a low serum albumin level and edema.
-Nephrotic-range proteinuria is the loss of 3 grams or more per day of protein into the urine or, on a single spot urine collection, the presence of 2 g of protein per gram of urine creatinine.

-The first sign of nephrotic syndrome in children is usually swelling of the face; this is followed by swelling of the entire body.
-Adults can present with dependent edema. Fatigue and loss of appetite are common symptoms.

β’Urinary protein measurement
-Urinary protein is measured by a timed collection or a single spot collection.
-A timed collection is typically done over a 24-hour period, starting at 7 am and finishing the next day at the same time. In healthy individuals, less than 150 mg of total protein is present in a 24-hour urine collection.
-A single spot urine collection is much easier to obtain. When the ratio of urine protein to urine creatinine is greater than 2 g/g, this corresponds to 3 g of urinary protein per day or more.
