Scientists learn more about rare skin cancer that killed Bob Marley

Scientists learn more about rare skin cancer that killed Bob Marley

Acral melanomas, the rare type of skin cancer that caused musician Bob Marley’s death, are genetically distinct from other types of skin cancer. Cancer Research UK scientists have discovered that acral melanomas — the rare type of skin cancer that caused reggae musician Bob Marley’s death — are genetically distinct from other more common types of skin cancer, according to a study published in the journal Pigment Cell & Melanoma Research Continue reading

Bone tumour destroyed using incisionless surgery: First in North American child

Bone tumour destroyed using incisionless surgery: First in North American child

A patient at The Hospital for Sick Children (SickKids) is the first child in North America to have undergone a specialized procedure that uses ultrasound and magnetic resonance imaging (MRI) to destroy a tumor in his leg without piercing the skin. Doctors used an MRI to guide high-intensity ultrasound waves to destroy a benign bone tumor called osteoid osteoma. Continue reading

New hand-held device uses lasers, sound waves for deeper melanoma imaging

New hand-held device uses lasers, sound waves for deeper melanoma imaging

A new hand-held device that uses lasers and sound waves may change the way doctors treat and diagnose melanoma, according to a team of researchers from Washington University in St. Louis. The instrument, described in a paper published today in The Optical Society’s (OSA) journal Optics Letters , is the first that can be used directly on a patient and accurately measure how deep a melanoma tumor extends into the skin, providing valuable information for treatment, diagnosis or prognosis.

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
