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.
Cryotherapy is one of the newer treatments that is being
evaluated for use in the early stage of prostate cancer. This treatment kills
the cancer cells by freezing them. The freezing is accomplished by inserting a
freezing liquid (for example, liquid nitrogen or argon) through needles
directly into the prostate gland. The procedure is accomplished under the
guidance of ultrasound images. Actually, cryotherapy is not a new technique.
Rather, it is a modification of a procedure that was tried previously but had
an unacceptably high rate of complications. Thus, cryotherapy was used in the
1960s to freeze the lining of the stomach to treat ulcers but was discontinued
because it also severely damaged the lining of the stomach.
At present, cryotherapy is recommended for patients with
locally advanced prostate cancer who, for whatever reason, are not candidates
for the more established treatments. Cryotherapy is further being studied to
determine which other patients might benefit from this treatment. For example,
studies are under way to establish whether cryotherapy is beneficial as an
initial treatment for organ-confined (localized) prostate cancer. The
effectiveness of cryotherapy in eliminating prostate cancer, however, has not
yet been proven. We do know that sometimes the freezing liquid fails to kill
all of the cancer cells. Moreover, the potential side effects of this treatment
include damage to the urethra and bladder. This damage can cause obstruction
(blockage) of the urethra, fistulas (abnormal tunnels) that leak urine, or
serious infections.
What is HIFU for prostate cancer?
HIFU, which stands for high intensity focused ultrasound, was first developed as a treatment of benign prostatic hyperplasia (BPH) and now is also being used as a procedure for the killing of prostate cancer cells. This procedure utilizes transrectal (across the rectum) ultrasound that is highly focused into a small area, creating intense heat of 80-100 C, which is lethal to prostate cancer tissue. However, the published clinical experience with HIFU for this application is limited and
the procedure is not yet approved by the FDA for use in the United States.
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.
