combination included hormones, animal organ cells, steroids, vitamins, enzymes, and amphetamines, and possible potential side effects included hyperactivity, hypertension, impaired judgment, nervousness, and mood swings. Kennedy at one time was regularly seen by three doctors, one of whom, Max Jacobson, was unknown to the other two, as his mode of treatment was controversial and used for the most severe bouts of back pain. Into late 1961, disagreements existed among Kennedy's doctors concerning his proper balance of medication and exercise. Kennedy preferred the former because he was short on time and desired immediate relief. During that time, the president's physician, George Burkley, did set up some gym equipment in the White House basement, where Kennedy did stretching exercises for his back three times a week. Details of these and other medical problems were not publicly disclosed during Kennedy's lifetime. The President's primary White House physician, George Burkley, realized that treatments by Jacobson and Travell, including the excessive use of steroids and amphetamines, were medically inappropriate, and took action to remove Kennedy from their care. In 2002, Robert Dallek wrote an extensive history of Kennedy's health. Dallek was able to consult a collection of Kennedy-associated papers from the years 1955–1963, including X-rays and prescription records from the files of Dr. Travell. According to Travell's records, during his presidential years Kennedy suffered from high fevers; stomach, colon, and prostate issues; abscesses; high cholesterol; and adrenal problems. Travell kept a "Medicine Administration Record", cataloging Kennedy's medications: "injected and ingested corticosteroids for his adrenal insufficiency; procaine shots and ultrasound treatments and hot packs for his back; Lomotil, Metamucil, paregoric, phenobarbital, testosterone, and trasentine to control his diarrhea, abdominal discomfort, and weight loss; penicillin and other antibiotics for his urinary-tract infections and an abscess; and Tuinal to help him sleep." Family incidents Kennedy's older brother Joseph P. Kennedy Jr. was killed in action in 1944 at age 29 when his plane exploded over the English Channel during a first attack execution of Operation Aphrodite during World War II. His sister Rose Marie "Rosemary" Kennedy was born in 1918 with intellectual disabilities and underwent a prefrontal lobotomy at age 23, leaving her incapacitated until her death in 2005. Another sister Kathleen Agnes "Kick" Kennedy died in a plane crash en route to France in 1948. His wife Jacqueline Kennedy suffered a miscarriage in 1955 and a stillbirth in 1956: a daughter informally named Arabella. A son, Patrick
