Dr. Janss is very personable, and I felt she cared about me as a person and as a patient. However, she did not adequately explain the procedure she performed on a pre-cancerous growth on my nose beforehand--I was shocked when she pointed a "gun" and "shot" a blast of some substance at my face and eye-glasses. I pulled back. She laughed. "This won't hurt your glasses." She also prescribed 3 or 4 medications, some of which cannot be filled by mail order pharmacy because they are OTC. I'm still working on straightening that out.

I felt that the appointment was rushed. Also, and more importantly, I had stated clearly to the nurse that I intended to leave my mask on for the entire appointment. They may not have had an opportunity to give Dr Janss this information, which I suppose is understandable. However, I did not have an opportunity to remind the doctor of this personal boundary when she grabbed my mask and pulled it down in the middle of the skin check. She didn't let me know she was going to remove the mask, nor did she ask if she could do so. I have PTSD and was frozen for a moment, all I could do was try to stay present enough to not completely dissociate or hyperventilate. I have medical trauma (as well as multiple other forms of trauma), so I was unable to assert myself after my boundary was violated. I understand Dr Janss likely did not mean any harm. And, as I stated earlier, I don't know if the nurse was able to relay my message to the doctor. As I said, the appointment felt very rushed, so I did not feel there was adequate opportunity for me to re-assert my need to leave my mask on before the doctor pulled it down. I hope that, in the future, Dr Janss will provide patients with more warning before removing their clothing (including a mask), or perhaps more preferably- ask if the patient can remove the article of clothing themselves.

A year ago Dr. Gerta Janss discovered a melanoma on my scalp during a routine exam and immediately performed a biopsy confirming her suspicions. She went the extra mile immediately setting up an excision with a colleague. Happily, the melanoma was only in the epidermis layer. Dr. Janss is so thorough and focused as you might guess, since finding a melanoma on a scalp is no small task. She has been treating me for over the years and I trust her completely.

Disclosures

Gerta S. Janss, MD reported no external professional relationships for calendar year 2021.

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care. These relationships are important in achieving scientific breakthroughs and in establishing the effectiveness and safety of promising new therapies. In order to assure objectivity in clinical research and patient care, the Northwestern University Feinberg School of Medicine (Feinberg), Northwestern Memorial HealthCare, Children's Hospital of Chicago Medical Center, and the Shirley Ryan AbilityLab have adopted integrity policies that require research and clinical faculty (in full-time, part-time, and unpaid/voluntary categories) to report compensated and uncompensated external industry relationships. Patients are encouraged to discuss these disclosures with their physician as well as to inquire as to how these relationships are overseen by Feinberg.
