Variables Identified in Congenital Melanocytic Nevi
WEDNESDAY, Aug. 22 (HealthDay News) -- In patients with congenital melanocytic nevi, the major dermoscopic patterns vary by age and lesion site, according to a report published in the August issue of the Archives of Dermatology.
Stem Cell Population Improves Healing in Diabetic Mice

Newer Skin Tightening Method Rates High with Patients
WEDNESDAY, Aug. 22 (HealthDay News) -- Newer methods of non-surgical skin tightening using monopolar radiofrequency with lower-energy probes and multiple passes reduce heat pain and increase patient satisfaction with treatment expectations, according to a report published in the August issue of Dermatologic Surgery.
Resident Duty-Hour Cuts Curb Surgeon Job Satisfaction
WEDNESDAY, Aug. 22 (HealthDay News) -- Reforms limiting resident duty hours are increasing surgeons' workloads and may be negatively affecting patient care, researchers report in the August issue of the Archives of Surgery.
Port-Wine Stains Respond Best to Variable-Pulse Laser
TUESDAY, Aug. 21 (HealthDay News) -- Variable-pulse pulsed dye laser treatment is more effective than conventional pulse dye laser therapy for the treatment of port-wine stains, but neither treatment can effectively treat vessels less than 30 μm in diameter, according to study findings published in the August issue of Dermatologic Surgery.
Risky Tanning Behaviors More Common in Hispanic Teens
MONDAY, Aug. 20 (HealthDay News) -- White Hispanic high school students are more than twice as likely to use tanning beds as non-Hispanic white students, and they are also significantly less likely to protect themselves against skin cancer, according to a report in the August issue of the Archives of Dermatology.
Greater Distance to Doctor Linked to Thicker Melanoma
MONDAY, Aug. 20 (HealthDay News) -- The thickness of a patient's melanoma is associated with the distance that a patient must travel to see the health care provider who diagnoses it, researchers report in the August issue of the Archives of Dermatology.
Study Sheds Light on Penile Melanoma
FRIDAY, Aug. 17 (HealthDay News) -- Primary mucosal penile melanoma has a similar prognosis as cutaneous melanoma when the tumors are of comparable thickness, according to a report in the August issue of Urology. Wide local excision and sentinal node biopsy for clinically negative lymph nodes is the recommended treatment.
Skin Lesions Common in Type 1 Diabetics
FRIDAY, Aug. 17 (HealthDay News) -- Cutaneous manifestations, including lesions, are common in younger people with type 1 diabetes and their timing and duration could help determine intervention strategies, according to the results of a study published in the August issue of Diabetes Care.
SOX9 Protein is Key Regulator of Melanin in Skin Cells
THURSDAY, Aug. 16 (HealthDay News) -- The SOX9 protein, previously known for its role in sexual determinism and skeletal disorders, may play an important role in skin-cell development and melanin production, according to a report published online Aug. 16 in the Proceedings of the National Academy of Sciences.
Eye Cancer Risk Elevated in Kidney-Transplant Patients
THURSDAY, Aug. 16 (HealthDay News) -- Kidney-transplant patients have an increased risk of ocular squamous cell carcinoma, according to the results of a study published online Aug. 14 in the Journal of the National Cancer Institute.
