Howard County General Hospital has appointed Dr. Tin Maung Oo, medical director of the hospital's Hospitalist Program.

Hospitalists are physicians who specialize in the care of hospitalized patients and whose practice is in the hospital, not in an office. A hospitalist is assigned to care for an inpatient if he does not have a primary care physician or if his primary care physician has referred him to the program.

Oo was born and raised in Burma, now Myanmar, where he completed medical school in 1973. He worked as an epidemiologist for the Minnesota State Department of Health before completing his internal medicine residency at Woodhull Hospital in Brooklyn, N.Y. He later joined an internal medicine practice in Chattanooga, Tenn., where he worked for nine years before moving to St. Mary's Hospital in Jefferson City, Mo., to implement and lead the hospitalist program there.

The hospital also announced the following appointments:

* Dr. Walter F. Atha as director of HCGH's Department of Emergency Medicine. A member of the staff since 2000, he most recently served as deputy director of the department, then as interim director.

* Dr. Michael G. Macon, as chairman of the Department of Surgery. He previously served as assistant chairman of surgery.

* Dr. Andrew W. Mortonhas as chairman of the Diagnostic Imaging Department. He has been the primary interventional radiologist at HCGH since 2003 and has served as assistant chairman of the Diagnostic Imaging Department since 2004.

* Dr. James D. Nowakowski, who has been on the medical staff since 2007, as chairman of the Department of Anesthesiology.

* Dr. Joseph M. Schwartz as chairman of the Department of Psychiatry. On staff at HCGH since 2004, he played an active role in the design and implementation of the hospital's emergency behavioral unit.

* Dr. Michael E. Silverman, as chairman of the Department of Medicine. A staff member since 1994, he previously served as assistant chairman of medicine.

Dr. Charles Hesdorffer has been named chief of the Division of Hematology at Johns Hopkins Bayview Medical Center. He previously was director of clinical hematology for the Johns Hopkins Hospital.

Hesdorffer received his MBBCh and Master of Medicine degrees from the University of the Witwatersrand in Johannesburg, South Africa. He completed his fellowship in hematology and oncology at the College of Physicians and Surgeons of Columbia University in New York. Before coming to Hopkins, Hesdorffer held positions at New York-Presbyterian Hospital in New York and Hackensack University Medical Center in New Jersey.
