Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
Dr. Lee was born in Shanghai, China, and received his college and medical training in the United States. He is fluent in English and three Chinese dialects. He graduated with chemistry departmental honors from Harvey Mudd College. He was appointed president of AOA society at UCLA School of Medicine. He underwent internal medicine residency and gastroenterology fellowship training at Cedars Sinai Medical Center.
Chemotherapeutic agents, or chemotherapy, are anticancer
drugs. They are used (for hormone resistant prostate cancer) as a palliative treatment (palliation
to relieve symptoms) in patients with
advanced cancer for whom a cure is unattainable. Recall that the goal of
palliation is simply to slow the tumor's growth and relieve the patient's
symptoms. Chemotherapy is not ordinarily used for organ-confined or locally
advanced prostate cancers because a cure in these cases is possible with other
treatments. Currently, chemotherapy is used only for advanced metastatic
prostate cancers that have failed to respond to other treatments.
Several chemotherapeutic agents have been used effectively
to palliate metastatic prostate cancer. One such agent is estramustine (Emcyt).
Another agent called mitoxantrone (Novantrone) has been shown to be effective in
combination with prednisone for palliating androgen-independent prostate cancer. As mentioned previously, metastatic tumors that have not responded specifically to hormonal therapy are referred to as castrate-resistant prostate cancers. Newer chemotherapy medicines like
docetaxel (Taxotere) have shown some promise in prolonging the survival of some patients with extensive prostate cancer. They may also decrease the pain related to widespread cancer. However, this comes at the cost of significant side effects that may impact quality of life.
The more common side effects of chemotherapy include
weakness, nausea, hair loss, and suppression of the bone marrow. The
suppression of marrow, in turn, can decrease the red blood cells (causing
anemia), the white blood cells (leading to infections), and the platelets
(resulting in bleeding).
Prostate Cancer - Symptoms At Onset Of DiseaseQuestion: The symptoms of prostate cancer can vary greatly from patient to patient. What were your symptoms at the onset of your disease?
Prostatitis is a painful condition of the prostate gland. There are four types of prostatitis, acute bacterial, chronic bacterial, chronic pelvic pain syndrome, and asymptomatic inflammatory prostatitis. Diagnosis is made with a digital rectal exam, urinalysis, ultrasound, MRI, biopsy, or blood test. Treatment depends upon the type of prostatitis.
Impotence, also known as erectile dysfunction, is a common
problem among men characterized by the consistent inability to sustain an
erection sufficient for sexual intercourse or the inability to achieve
ejaculation, or both. Impotence can have emotional causes but most often it is
due to a physical problem.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Hydronephrosis is a condition in which the kidney swells, due to a backup of urine. Hydronephrosis generally occurs with another disease.Symptoms of hydronephrosis include nausea, vomiting, urinary tract infection, fever, painful urination, increased urinary frequency and urgency, flank pain, and swelling of the abdomen. Treatment of hydronephrosis depends on the cause.
Benign prostatic hyperplasia (BPH or enlarged prostate) is very common in men over 50 years of age. This noncancerous enlargement of the prostate can impede urine flow, slow the flow of urine, create the urge to urinate frequently and cause other symptoms like complete blockage of urine and urinary tract infections. Treatment may involve watchful waiting, medication, or surgery.
There are many types of urinary incontinence (UI), which is the accidental leakage of urine. These types include stress incontinence, urge incontinence, and overflow incontinence. Urinary incontinence in men may be caused by prostate or nerve problems. Treatment depends upon the type and severity of the UI and the patient's lifestyle.
Though it's difficult to say why some people develop cancer while others don't, research shows that certain risk factors increase a person's odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
Enjoying a satisfying sex life as we age is important to both physical and mental health. As we age, diseases and conditions may pose challenges in our sexual health, and sexual experiences. Learn how to manage your conditions and still have a gratifying sex life as you age.
Men's health is an important component to a happy lifestyle and healthy relationships. Eating healthy, exercise, managing stress, and knowing when to have medical tests for a particular age is key to disease prevention in men.
Most often, caregivers take care of other adults who are ill or disabled. Less often, caregivers are grandparents raising their grandchildren. The majority of caregivers are middle-aged women. Caregiving can be very stressful, so it's important to recognize when it's putting to much strain on you and to take steps to prevent/relieve stress.
Disease prevention in men includes routine screening tests that are part of basic prevention medicine. Take an active role in your own health care and discuss screening tests with your doctor early in life. Age of screening and timing of screening depends upon the condition being assessed.
