Chemical peeling with 35% glycolic acid for the treatment of disseminated facial verruca plana: A randomized, split-face, evaluator-blinded trial.

Disseminated facial verruca plana is a chronic disorder that causes significant psychological distress. However, safe and effective treatment is lacking. This study aimed to explore the efficacy and safety of 35% glycolic acid (GA) for the treatment of disseminated facial verruca plana. A split-face clinical trial was conducted to explore the efficacy and safety of using chemical peeling with 35% GA for the treatment of disseminated facial verruca plana. One side of the face was applied with 35% GA once every fortnight for a total of three times. Adapalene gel was applied every night to the other side of the face as the control. The clearance rate of lesions was evaluated at different time points. Between June 2020 and December 2020, 30 patients with disseminated verruca plana who visited the Dermatology Hospital of Southern Medical University were enrolled. After three chemical peelings with 35% GA that was applied at 2-week intervals, 15 (50%) patients achieved >70% lesion reduction. The same effective rate in the adapalene gel-treated side of the face was documented in eight patients. Subgroup analysis showed a higher clearance rate in patients with a shorter disease duration. Moreover, concurrent improvements in facial roughness were observed in the 35% GA-treated group. Adverse effects including mild erythema and desquamation were observed during chemical peeling with 35% GA. In conclusion, chemical peeling with 35% GA could be a safe and effective option for treating disseminated facial verruca plana, especially for those who desire skin improvement.

Laparoscopic surgery contributes more to nutritional and immunologic recovery than fast-track care in colorectal cancer.

BACKGROUND: Many clinical trials had repeatedly shown that fast-track perioperative care and laparoscopic surgery are both preferred in the treatment of colorectal cancer. But few studies were designed to explore the diverse biochemical impacts of the two counterparts on human immunologic and nutritional status. METHODS: Ninety-two cases of colorectal cancer patients meeting the inclusion criteria were randomized to four groups: laparoscopy with fast-track treatment (LAFT); open surgery with fast-track treatment (OSFT); laparoscopy with conventional treatment (LAC); open surgery with conventional treatment (OSC). Peripheral blood tests including nutritional factors (albumin, prealbumin, and transferrin), humoral immunologic factors (IgG, IgM, and IgA), and cellular immunologic factors (T and NK cells) were evaluated. Blood samples were collected preoperatively (baseline) and 12 and 96 h after surgery (indicated as POH12 and POH96, respectively). RESULTS: Albumin, transferrin, prealbumin, and IgG levels were the highest in the LAFT group for both POH12 and POH96 time intervals. Repeated measures (two-way ANOVA) indicated that the difference of albumin, transferrin, and IgG level were attributed to surgery type (P < 0.05) and not perioperative treatment (P > 0.05). Only in the laparoscopy-included groups, the relative albumin and IgG levels of POH96 were obviously higher than that of POH12. CONCLUSION: Laparoscopic surgery accelerated postoperative nutrition and immune levels rising again while fast-track treatment retarded the drop of postoperative nutrition and immune levels. Laparoscopic surgery might play a more important role than fast-track treatment in the earlier postoperative recovery of nutritional and immunologic status. Combined laparoscopic surgery with fast-track treatment provided best postoperative recovery of nutrition and immune status. These results should be further compared with the clinical outcomes of our FTMDT trial (clinicaltrials.gov: NCT01080547).
