Understanding melanoma development

Understanding melanoma development

A new study by University of Kentucky researchers shows how a genetic defect in a specific hormonal pathway may make people more susceptible to developing melanoma, the deadliest type of skin cancer. Fair-skinned people who tend to burn (rather than tan) from sun exposure have a much higher risk for melanoma than darker-skinned people. On the surface, it appears that the amount of melanin, the natural substance in the skin that determines pigment and acts as the skin’s “natural sunscreen,” would be the only determinant of melanoma risk Continue reading

Insulin pumps result in better blood sugar control than multiple daily injections in people with type 2 diabetes

Type 2 diabetes is usually controlled by diet and medication, but most people with advanced disease also end up needing insulin therapy to achieve control of their blood sugar. Continue reading

Get insects to bug off this summer

Summer means an increase in bug and insect activity. How do you know which insects are harmful, what diseases they carry and how to safely avoid them? “Mosquitoes and ticks are the two pests you primarily want to avoid because they potentially carry infectious diseases,” says Jennifer Layden, MD, infectious disease specialist at Loyola University Health System.

New biometric watches use light to non-invasively monitor glucose, dehydration, pulse

Monitoring a patient’s vital signs and other physiological parameters is a standard part of medical care, but, increasingly, health and fitness-minded individuals are looking for ways to easily keep their own tabs on these measurements. Continue reading

Mechanism that forms cell-to-cell catch bonds found by researchers

Mechanism that forms cell-to-cell catch bonds found by researchers

Certain bonds connecting biological cells get stronger when they’re tugged. Those bonds could help keep hearts together and pumping; breakdowns of those bonds could help cancer cells break away and spread. Those bonds are known as catch bonds and they’re formed by common adhesion proteins called cadherins. Continue reading

Lasers, night-vision technology help improve imaging of hidden lymphatic system

Lasers, night-vision technology help improve imaging of hidden lymphatic system

The human lymphatic system is an important but poorly understood circulatory system consisting of tiny vessels spread throughout the body. This “drainage” network helps guard against infections and prevents swelling, which occasionally happens when disease or trauma interrupts normal lymphatic function. Chronic swelling is the hallmark of a painful, incurable condition known as lymphedema, which often occurs after cancer therapy and can leave the limbs and other body parts disfigured for life.

Rare skin cancer on palms, soles more likely to come back compared to other melanomas

Rare skin cancer on palms, soles more likely to come back compared to other melanomas

A rare type of melanoma that disproportionately attacks the palms and soles and under the nails of Asians, African-Americans, and Hispanics, who all generally have darker skins, and is not caused by sun exposure, is almost twice as likely to recur than other similar types of skin cancer, according to results of a study in 244 patients. The finding about acral lentiginous melanoma, as the potentially deadly cancer is known, is part of a study to be presented May 31 by researchers at the Perlmutter Cancer Center of NYU Langone at the annual meeting of the American Society of Clinical Oncology in Chicago Continue reading

A better way to treat ACE inhibitor angioedema in the ED

A better way to treat ACE inhibitor angioedema in the ED

Investigators at the University of Cincinnati have found a safe and effective treatment for life-threatening angioedema attacks in the emergency department. In angioedema, patients experience a rapid swelling of the skin and subcutaneous tissues — which, in some cases, can lead to airway obstruction and suffocation. Continue reading
