RESUMO
BACKGROUND: The Sun Protection Outreach Teaching by Students (SPOTS) program addresses an unmet need by training medical students to teach adolescents about skin cancer prevention and early detection. OBJECTIVE: To measure (1) changes in adolescents' knowledge, attitudes, and behaviors regarding sun protection and (2) the impact on medical students' confidence in skin cancer preventive counseling. METHODS: Pre-SPOTS and 1-month post-SPOTS program surveys were completed by adolescent participants and medical student instructors. RESULTS: Amongst adolescent students, analysis of 1,142 pre-program surveys and 618 post-program surveys revealed statistically significant improvements in knowledge, attitudes, and behaviors. Among the favorable results, 26%, 41%, and 20% improvements over baseline were observed in SPF knowledge, preference for natural untanned skin, and intent to wear sunscreen, respectively (p < .001). One-third of adolescents reported having tried to increase sunscreen use. Amongst medical students, analysis of 78 pre-teaching and 74 post-teaching surveys revealed an increase in feeling "very confident" in counseling patients, from 23% pre-teaching to 82% post-teaching (p < .001). CONCLUSION: SPOTS demonstrated a dual benefit to adolescents and medical students. The program is available for dermatologists to implement in their communities.

BACKGROUND: Access to dermatologists is low among Medicaid-insured patients. Higher clinic nonattendance among Medicaid-insured patients might affect provider decisions to accept these patients. OBJECTIVE: To determine the effect of different scheduling policies on the attendance among children seen at a pediatric dermatology clinic. METHODS: In this retrospective review, we compared nonattendance among children for 3 different scheduling policies implemented over 3 consecutive years. The scheduling policies used were a first-available open scheduling policy, a 2-week in advance scheduling policy, and a 4-week in advance scheduling policy. Subset analyses were performed by clinic location and insurance type. RESULTS: The interval between scheduling and appointment date was directly related to nonattendance rates; rates were higher for Medicaid-insured than privately insured patients. Open scheduling was associated with a 37% nonattendance rate for Medicaid-insured patients and 18% nonattendance rate for privately insured patients. A 4-week in advance scheduling policy significantly decreased the nonattendance rate to 19% among Medicaid-insured and 7% among privately insured patients. A 2-week in advance policy further decreased the nonattendance rate to 11% among Medicaid-insured patients and 4% among privately insured patients. LIMITATIONS: This is a retrospective study, and same-day cancellations were not tracked. CONCLUSION: Decreasing the time interval between scheduling and appointment dates can significantly decrease nonattendance. This strategy might help dermatologists incorporate more Medicaid-insured patients into their practices.

BACKGROUND: There is disparity in access to outpatient care for Medicaid beneficiaries. This inequity disproportionately impacts children. Access for children with skin disease may be especially limited. OBJECTIVE: We sought to compare access to dermatologists for new pediatric patients insured by Medicaid versus a private plan. METHODS: We surveyed 13 metropolitan markets by conducting secret-shopper scripted telephone calls to dermatology providers listed by Medicaid health plans. Paired calls, differing by insurance type, were made to each office on the same day, portraying a parent requesting a new appointment for a child with eczema. RESULTS: We called the offices of 723 Medicaid-listed providers. Final analysis included 471 dermatologists practicing general dermatology. Of these, an average of 44% refused a new Medicaid-insured pediatric patient. The average wait time for an appointment did not significantly vary between insurance types. Assuming that dermatologists not listed as Medicaid providers do not see Medicaid-insured children, our data indicate that pediatric Medicaid acceptance rates ranged from 6% to 64% by market, with an overall market size-weighted average acceptance rate of 19%. Relative reimbursement levels for Medicaid-insured patients did not correlate with acceptance rates. LIMITATIONS: Although the most current health plan directories were used to create calling lists, these are dynamic. The sample sizes of confirmed appointments were in part limited by a lack of referral letters and/or health plan identification numbers. Only confirmed appointments were used to calculate average wait times. CONCLUSIONS: Access to dermatologists is limited for Medicaid-insured children with eczema.

We report a case of giant cell arteritis (GCA) in an elderly woman. The patient presented to her dermatologist with a reticulated, purpuric patch on her frontal-temporal scalp and forehead that was associated with unilateral head pain. A punch biopsy of the lesion was suspicious for GCA, which was later confirmed by temporal artery biopsy. This case highlights a potential early cutaneous finding of GCA that may aid the clinician in the diagnosis before more severe complications occur.

Amino acid transporter B(0)/ASC transporter 2 (ATB(0)/ASCT2) is responsible for most glutamine uptake in human hepatoma cells. Because this transporter is not expressed in normal hepatocytes, we hypothesized that its expression is necessary for growth of human liver cancer cells. To test this hypothesis, Sloan Kettering hepatoma (SK-Hep) cells were stably transfected with an inducible 1.3-kb ATB(0)/ASCT2 antisense RNA expression plasmid under the transcriptional control of mifepristone, a synthetic steroid. Induced antisense RNA expression in monolayer cultures decreased ATB(0)/ASCT2 mRNA levels by 73% and glutamine transport rates by 65% compared with controls after 24 h, leading to a 98% decrease in cell number after 48 h. Cellular death was attributable to apoptosis based on cellular blebbing, caspase-3 activation, vital dye and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining, and poly-(ADP-ribose) polymerase (PARP) cleavage. Transporter knockdown also markedly increased activities of caspases-2 and -9, marginally enhanced caspase-8 activity, and dramatically increased ASCT1 mRNA levels, presumably as a futile compensatory response. Apoptosis elicited via transporter silencing was not attributable to the double-stranded RNA-dependent protein kinase R (PKR) pathway. For comparison, glutamine deprivation also caused apoptotic cell death but with slower temporal kinetics, stimulated caspases-2 and -3 but not caspases-8 or -9 activities, and led to considerable PARP cleavage. Thus ASCT2 suppression exerts proapoptotic effects transcending those of glutamine starvation alone. We conclude that ATB(0)/ASCT2 expression is necessary for SK-Hep cell growth and viability and suggest that it be further explored as a selective target for human hepatocellular carcinoma.
