Henry P. Parkman, MD, is Professor of Medicine in the Gastroenterology Section of the Department of Medicine at Temple University School of Medicine. Dr. Parkman's gastroenterology training began with a GI fellowship at the University of Pennsylvania. His research investigated the inhibitory neural circuitry of the lower esophageal sphincter (LES)--the barrier preventing gastroesophageal reflux. At the University of Pennsylvania, he also compared the clinical outcomes and costs of pneumatic dilation and surgical esophagomyotomy for treatment of patients with achalasia, a disorder involving abnormal LES neural control. Dr. Parkman extended his research training with a National Institutes of Health research training fellowship in the Department of Physiology at Mayo Clinic where he studied the inferior mesenteric ganglion and its involvement in colonic motility.
Dr. Parkman has been at Temple University School of Medicine for
20 years where he is Director of the Clinical GI Motility
Laboratory at Temple University Hospital. He has developed
expertise in a comprehensive array of GI motility tests for
clinical evaluation of patients, including specialized tests of
gastric motility. His clinical research studies have focused
primarily on esophageal and gastric motility in normal individuals
and on clinical motility disorders of the esophagus and stomach.
His main clinical focus has been treating patients with GI motility
disorders, primarily gastroparesis. Dr. Parkman is a past President
of the American Neurogastroenterology and Motility Society. Dr.
Parkman has been co-director of the ANMS Motility Courses held in
2002, 2004, 2006, 2008, and 2010.
Richard W. McCallum, MD, FACP, FRACP (Aust), FACG, is Professor and
Founding Chairman of the Department of Internal Medicine, Texas
Tech University Health Sciences Center at El Paso. Dr. McCallum
also serves as the Medical Director of the Diagnostic Center for GI
Motility and Functional Bowel Disorders serving as a referral
center for patients locally, regionally, and nationally.
After completing his undergraduate studies at the University of Queensland, he earned his medical degree at the Queensland Medical School in Brisbane, Australia. Dr. McCallum completed gastroenterology fellowship training at the University of California Los Angeles and Wadsworth VA Medical Center. He joined the faculty of Yale University School of Medicine in 1996. Dr. McCallum was Professor of Medicine, Chief, and Program Director of the Division of Gastroenterology, Hepatology, and Nutrition at the University of Virginia School of Medicine, Charlottesville from 1985 to 1996 where he was awarded the Paul Janssen Endowed Chair and Professorship. From 1996 to 2004, Dr. McCallum was then Chief and Program Director, Division of Gastroenterology and Hepatology, University of Kansas Medical Center, Kansas City. Dr. McCallum was the Director of the Center for GI Nerve and Muscle Function and Chief of Division of GI Motility, University of Kansas School of Medicine from 2004 to 2009.
Among his professional honors and memberships are Fellow of the American College of Physicians, Fellow of the Royal Australian College of Physicians, Fellow of the American College of Gastroenterology, member of the American Society for Clinical Investigation, President of the Southern Society for Clinical Investigation, and President of the International Electrogastrogram Society. He is currently a member of the American Neurogastroenterology and Motility Society (ANMS) Council and has been Co-Director of the ANMS courses on Clinical Practice conducted in 2002, 2004, 2006, 2008 and 2010. He was the organizer and host for two national programs for ANMS in Charlottesville, Virginia in 1994 and Kansas City, Kansas in 2002.
Dr. McCallum's area of clinical interest and research is the
field of GI motility, neurogastroenterology, and functional bowel
disorders. He has been focused on advancing knowledge related to
pathophysiology, diagnostic approaches, pharmacology, and device
technology. He is a pioneer in the area of gut electrophysiology
and developed the concept of electrical "pacing" of the stomach to
treat gastroparesis, particularly related to diabetes mellitus.
Recently he has rediscovered and extensively advanced new knowledge
in understanding and managing a cyclic vomiting syndrome in
adults.
Satish S.C. Rao, MD, PhD, FRCP (Lon), received his MD from Osmania
Medical College, Hyderabad, India; his PhD from the University of
Sheffield, UK; and the Fellowship of the Royal College of
Physicians (FRCP) in London, UK, in 1997. Currently, Dr. Rao is a
Professor of Medicine and Director, Neurogastroenterology and GI
Motility Program, Department of Internal Medicine, University of
Iowa Carver College of Medicine, Iowa City.
Dr. Rao is one of a rare breed of academicians who has excelled as an outstanding researcher, distinguished educator, and as a master clinician. Dr. Rao's research interests focus on the pathophysiology and treatment of irritable bowel syndrome, constipation and fecal incontinence, and visceral pain, particularly esophageal chest pain, dietary fructose intolerance, and neurobiological mechanisms of biofeedback therapy. He has pioneered several new techniques of evaluating and treating motility disorders. He has received numerous awards including the American Gastroenterological Association (AGA) Distinguished Clinician Award, AGA Masters Award for Outstanding Clinical Research, and the AGA Distinguished Educator Award. In 2005, he also received the American College of Gastroenterology (ACG) Auxiliary Research Award, the highest research award from ACG. In 2009, he was awarded the International Foundation for Functional GI disorders Senior Clinical Investigator Award and in 2010 the University of Iowa Regents Award for Faculty Excellence.
A very productive, federally funded investigator and sought-after speaker, Dr. Rao has edited 3 books, Disorders of the Anorectum (2001), Anorectal and Pelvic Floor Disorders (2008) for Gastroenterology Clinics of North America, and Gastrointestinal Motility--Testsand Problem-Oriented Approach. He has published more than 250 articles. Dr. Rao is a member of several distinguished medical and research societies. He is the current President of the American Neurogastroenterology and Motility Society.
"...this disorder focused part of the book makes the book cohesive
as a stand-alone publication because it ties the technical and
clinical aspects of the testing procedures together. Overall, this
text makes an important contribution to the gastroenterology
literature. No other single text exists on the topic of this
comprehensive list of GI testing modalities written with not only
the physician, but nurses and technical staff in mind."

"I find this book a useful reference. The sheer breadth of topics
covered is probably its greatest strength."
