Johns Hopkins researchers have found evidence that Tourette's syndrome, which causes involuntary muscle contractions and bursts of words and noise, may be triggered in part by an infection.
Johns Hopkins physicians have designed a series of implants that restore bulk to weakened vocal cords, returning the power of speech to those who have lost their voices from paralysis associated with throat cancers, strokes or other conditions. The patented implants were approved by the U.S. Food and Drug Administration in early spring.
Johns Hopkins scientists have developed a vaccine that, in mice, can alert the immune system to the presence of stray cancer cells and significantly reduce their blood-borne spread.
In a study of prostate cancer at different ages, Johns Hopkins researchers have found that at diagnosis, older men have more extensive disease than younger men even if their prostate specific antigen (PSA) levels are the same. PSA is a protein made by the prostate; rising blood levels suggest that the prostate is enlarged or even cancerous.

Alarmed by the epidemic rate at which children are being exposed to violence - on the streets, in their communities, and through the media - the Johns Hopkins Children's Center has opened an Office for the Prevention of Violence to address the needs of traumatized children and to draw attention to a rapidly escalating public health threat.

Researchers at Johns Hopkins Bayview Medical Center have found that as the hours of television watched by American children increases, so does their weight.
Johns Hopkins researchers have identified genetic mutations that appear to cause or contribute to more than half of all non-inherited or sporadic cases of the deadly muscle disease amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease.
Vascular surgeons at Johns Hopkins are participating in a nationwide test of a procedure that uses 3-D images and a metal-supported cloth tube to repair stretched and weakened abdominal arteries before they burst and kill.
Johns Hopkins researchers have new evidence supporting a controversial theory that asthma is partially caused by the failure of deep breaths to relax constricted lung muscles enough to let in more air.
One in 10 health care workers frequently exposed to rubber surgical and examination gloves is on the cusp of developing allergy symptoms that could seriously affect both their health and their careers, according to a new study from Johns Hopkins Medical Institutions.
Pelvic congestive syndrome, a painful disorder in women, which often goes undiagnosed and untreated, can usually be cured by plugging blood vessels in the ovaries, according to a study by a Johns Hopkins radiologist.
A widely used operation to prevent stroke by removing blockages from blood vessels in the neck is safe even for the elderly -- and safest and least expensive when done in hospitals performing the greatest number, a Johns Hopkins study has found.
Scientists at Johns Hopkins have developed the first precise, noninvasive means of measuring a chemical in the heart tied to the extent of muscle damage from a heart attack.
A five-year educational campaign to increase condom use in Thailand has led to a fivefold decrease in HIV infection among young army draftees in northern Thailand and a tenfold decrease in sexually transmitted diseases (STDs) overall, according to Johns Hopkins researchers.
Magnetic resonance imaging (MRI) of the heart after a heart attack may help determine which patients do well and which ones will later suffer complications such as recurrent heart attack, congestive heart failure, stroke or death, according to a study led by Johns Hopkins researchers.
Scientists at Johns Hopkins and the University of Pennsylvania have tracked down the gene responsible for a paralyzing disease that has plagued at least eight generations of a Maryland family, the Mattinglys.
Researchers from Johns Hopkins and Finland are showing that fancy mathematical footwork plus detailed magnetic resonance imaging pictures of the brain may add up to a better understanding of the experience of thinking.
Johns Hopkins researchers have found evidence that some cancer cells are such incredible sugar junkies that they'll self-destruct when deprived of glucose, their biological sweet of choice.
Inexpensive screening of all sexually active young women under 30 for Chlamydia trachomatis infection would vastly reduce infertility and the costly medical complications of this sexually transmitted disease, according to results of a Johns Hopkins study.
A Johns Hopkins physician has discovered that a 74-year-old woman originally diagnosed with a blood cell cancer actually had a very mild case of malaria that lasted for as many as 70 years. Once he nailed down the cause of her symptoms, he cured her within three days.
A Johns Hopkins evaluation of a drug commonly used to prevent rejection of kidney transplants has found that it also may help patients with severe symptoms of kidney disease.
Women get more tension headaches than men and people with advanced degrees suffer more often from tension headaches than the less educated, according to a recent study of tension headache prevalence conducted by researchers at the Johns Hopkins University School of Public Health.
According to research by a Johns Hopkins Bayview Medical Center physician, potato chips made with olestra don't cause any more digestive problems than regular-fat potato chips and, despite containing only half the calories, are just as filling. Olestra, a nonabsorbable fat substitute, has been making news headlines since its approval by the FDA two years ago for use in snack products.
Natural estrogens may offer some protection to premenopausal women threatened with severe brain damage during stroke, according to a study led by researchers at Johns Hopkins and the National Institutes of Health.

Researchers from Johns Hopkins, the Aaron Diamond AIDS Research Center (New York, N.Y.) and the University of California, San Diego, have shown that drug "cocktail" therapy for AIDS does not completely clear the body of HIV. Rather, small amounts of the virus remain "hidden" in immune system cells, unable to cause disease or develop resistance to anti-AIDS drugs.
