A Rochester physician who had sex with a patient at his clinic has been reprimanded by the Minnesota Board of Medical Practice.

Dr. Michael Priebe, 50, was one of two Minnesota physicians disciplined in November, the board said Friday. The agency also reprimanded two physician assistants for unethical and unprofessional conduct.

Priebe, a board-certified rehabilitation specialist, admitted having a sexual relationship with a woman he was treating for complications of injuries from an auto accident. Under state law, doctors are barred from sexual contact with patients.

According to the board, Priebe gave the patient his cell phone and pager numbers to "stay in touch" outside the clinic, met her at a restaurant for dinner, and "exchanged electronic messages of a personal nature." On one occasion, he admitted to the board, he had sex with the patient during a clinic appointment.

The board began an investigation after receiving a complaint in 2009. Under a settlement agreement, Priebe will be required to have a female chaperone present when examining female patients, take a course in professional ethics and pay $1,830 in fines.

In other disciplinary cases:

• Dr. Samuel Kriegler, a urologist in Virginia, Minn., was reprimanded following complaints that he performed an unusually high number of procedures, called urethral dilations, on female patients without any documented medical reason. An investigation found that, in "multiple patient cases," he performed the procedure improperly and failed to explore other options. Kriegler, 62, denied doing anything improper, saying his practice was consistent with his medical training in the 1970s, according to the board. However, Kriegler said he had since changed his practice to "better address" the concerns about diagnosis and treatment.

As part of a settlement agreement, Kriegler agreed to work under a supervising physician and take a course on female pelvic dysfunction. He was also ordered to write a paper following the course and submit it to the board for review.

• Luke Rylander, a physician assistant in St. Paul, was reprimanded for having a sexual relationship with a patient and ordered to pay $1,440 in fines.

• Mark Shoemaker, a physician assistant in Ramsey, was reprimanded and fined $1,945 for violating a previous board order. He was ordered to complete a course in emergency medicine.
