There have been anecdotal reports that local hyperthermia was effective in the treatment of viral warts. We conducted a randomized, patient-blinded, placebo-controlled trial to test the effect of local hyperthermia (44 degrees C for 30 min a day for 3 consecutive days plus 2 additional days 2 weeks later) on plantar warts. By the end of 3 months, 53.57% of patients (15/28) in the treatment group and 11.54% of patients (3/26) in the control group were cured (P < .01). The effect was not influenced by patient age, duration of disease, or number or size of lesions.

Frequent somatic mutations of BRAF (v-raf murine sarcoma viral oncogene homolog B) exon T1799A, which are implicated in the initial events of promutagenic cellular proliferation, are detected in both malignant melanomas (MM) and melanocytic nevi (MN). Most of the data regarding BRAF exon T1799A mutation have been from Caucasian cohorts, and a comprehensive screening of a homogeneous population is lacking. A total of 379 cases of MN and 195 cases of MM were collected from Chinese Han living in three geographical regions in China, i.e., northeast, southwest, and northwest China. BRAF exon T1799A mutation was detected by PCR and sequencing from microdissected tumors. In all, 59.8% cases of MN harbored BRAF exon T1799A mutation. Samples from regions with high UV exposure had higher detection rates than regions with lower UV exposure (73.5, 67.0, and 38.9%, respectively; χ(2) = 31.674, P = 1.59E-7). There were no differences in mutation rates between congenital and acquired MN; however, acquired MN with advanced age of onset had a higher mutation rate than those with younger age of onset (χ(2) = 13.23, P = 0.02). In all, 15.0% cases of MM harbored the BRAF mutation. The mutation rate in MM was not affected by region, histological type, gender, pattern of UV exposure, and age. The study suggests that the mutation is not necessarily associated with malignant transformation.

This study aims to assess the impact of childhood vitiligo on the psychological status and quality of life of their parents, and to determine how this varies according to their children's disease condition. The study included 50 families of children with vitiligo (a total of 75 participants) and 50 families of normal children (a total of 79 participants). The psychosocial impact of the disease on parents was measured using the Self-rated Health Measurement Scale (SRHMS) and the Dermatitis Family Impact Questionnaire (DFI). SRHMS scores for parents of children with vitiligo were significantly lower than for parents with normal children. In addition, women had lower scores than men in the study group. The mean DFI score in affected families was higher than in unaffected families. Parents of children with vitiligo have significant psychological problems, and their quality of life is poorer than for parents of normal children. In conclusion, parents of children with vitiligo need as much care and attention as their affected children.
