Patient case (clinical description): A 50-year-old woman comes to the clinic with intermittent ear discharge and sense of hearing loss on her left ear.  Past medical history is significant for obesity, hyperlipidemia, and diabetes mellitus.  Her medications include Metformin, Atorvastatin and Vit D supplement. Vital signs are normal. BMI is 37. Otoscopy shows a small perforation in the left tympanic membrane and a pearly mass behind the membrane.  Conduction hearing loss is noted in the left ear.  The remainder of the ear, nose, and throat examination is normal.

Patient's own account: I went to the clinic the other day because I had some fluid in my ear and I felt like I could not hear as well as I used to in my left ear. I'm a 50-year-old woman, and I have been obese for a while now. I have diabetes and cholesterol. I take some medication. I take metformin, atorvastatin, and vitamin D supplements. When I was admitted, my vitals were normal. My BMI is 37. When they looked into my ears, they said that my left tympanic membrane was broken and there was some fluid behind the membrane. During the hearing test, they could assess that my left ear suffers from hearing loss. They also performed ear, nose, and throat examinations that turned out to be normal.
