Writing - Which comes first? First presentation or Past history

If past history and general info are short and simple, write them first.
I am referring this patient, a widower, who is presenting with symptoms consistent with a bilateral inguinal hernia. He has been suffering from hypertension for 5 years for which he takes Noten, Aspirin and multivitamins. He is allergic to penicillin.

Otherwise, put current urgent thing first like emergency:

Thank you for seeing my patient, Margaret Leon, who has been very concerned about blood in her stools. She has seen blood in the toilet bowl on two occasions after bowel motion. She is very anxious and as well as that depressed because her father died of bowel cancer and she feels she may have the same condition.

Margaret has otherwise been quite healthy. She does not drink or smoke and is not taking any medication. She was slightly overweight six months ago with borderline high blood pressure.

or mixed history with initial presentation

I am writing to refer this patient, a 40 year old married man with two sons aged 3 and 5, who requires screening for prostate cancer.

Initial examination on 09/07/09 revealed a strong family history of related illness as elderly father was diagnosed with prostate cancer and mother was diagnosed as hypertensive.
