RESUMEN
INTRODUCTION: Progressive hemifacial atrophy (PHA) is a nonnegligible disease, and its treatment currently lacks consensus. We aim to conduct an analysis of PHA patients to summarize the postoperative effect. Moreover, we introduced the free serratus anterior muscle-fascial composite tissue flap as a safe and novelty surgical procedure for moderate-severe PHA. METHODS: This clinical study included four patients who received a free serratus anterior muscle-fascial composite tissue flap and 19 patients who received Coleman fat transplantation. Preoperative (preoperative photograph and imageological examination) and postoperative (postoperative photograph, complications, therapeutic effect, and satisfaction) assessments were performed for all PHA patients. Body Image Concern Inventory (BICI), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) were performed preoperatively and postoperatively. RESULTS: All the cases were cured with a good appearance with two kinds of operations. Free serratus anterior muscle-fascial composite tissue flap could correct face defects in one surgery and achieve good long time and short-time postoperative satisfaction in moderate-severe PHA. Fat transplantation could also enhance appearance in numerous operations for mild-moderate PHA. The volume of free-fat grafts decreased obviously after implantation in many cases. So, many patients (42.11%) accepted a series of operations to achieve satisfied postoperative effect. BICI, SAS, SDS score decreased a year later in all patients. CONCLUSION: Free serratus anterior muscle-fascial composite tissue flap transplantation is an effective and safe treatment for moderate to severe PHA.

The use of Integra has attracted great interest in the treatment of wounds with exposed bone or tendon, which may lead to associated morbidities. However, the use of Integra alone results in poor wound outcomes. We conducted a randomized clinical study to evaluate the combined effects of Integra and negative pressure wound therapy (NPWT). Thirty-six patients with wounds with exposed bone or tendons were treated with Integra alone and with a combination of Integra and NPWT (n = 18 respectively). Negative pressure (125 mm Hg) was applied intermittently till Integra was revascularized. The take rate of Integra and time taken from Integra coverage to skin transplantation was recorded for each case. The average take rate of Integra in the conventional treatment group (Integra with partial packing compression dressings) was lower than that for the new treatment group (Integra with NPWT) (p < 0.001, 95% CI: 6.44-0.20). The mean time period from Integra coverage to skin transplantation was longer for the conventional treatment group than for the new treatment group (p < 0.001, 95% CI: -13.18 to -11.24). The application of NPWT could potentially increase the take rate of Integra and shorten the duration of hospital stay. The use of Integra with NPWT could be a treatment option for wounds with exposed bone or tendon.

BACKGROUND: There is no article that studies whether the regional lymph node (RLN) status affects the prognosis of Merkel cell carcinoma (MCC). METHODS: The survival and disease data of MCC patients were obtained from the Surveillance, Epidemiological, and End Results (SEER) database. The overall survival (OS) and cause-specific survival (CSS) rates were endpoints. RESULTS: A total of 1822 patients were included, with a mean age of 72.5 years. The number of RLN-positive patients was 862 (47.3%), and the number of RLN-negative patients was 960 (52.7%). The regression analysis showed that primary site, sex, and tumor size were statistically significant and independent predictors of RLN status. The five-year OS and CSS of RLN-negative patients were 71.4% and 92.3%, respectively, which were much higher than those of RLN-positive patients (37.5% and 65.8%, respectively) (P <0.001). In univariate survival analysis, positive RLN significantly predicted deterioration of OS and MSS (P <0.001). In multivariate analysis, RLN status had no statistically significant effect on patient prognosis. CONCLUSION: The prognosis of patients with RLN metastasis is worse than that of patients without RLN metastasis, but RLN status is not an independent predictor of the prognosis of patients with MCC.

BACKGROUND Merkel cell carcinoma (MCC) occurs primarily among elderly patients over 70 years old, but the ability to predict the prognosis of these elderly patients is poor. This population-based study aimed to identify prognostic risk factors for elderly patients with MCC. MATERIAL AND METHODS The survival and disease information of MCC patients age 65 years or older was downloaded from the SEER database, and all data were split into 2 groups based on age 80 years, with overall survival and MCC-specific survival as the main outcome indicators. RESULTS Application of the inclusion criteria yielded 1973 patients with MCC, of whom 55.6% were age 65-80 years. Among them, 1258 were males, accounting for 63.8%. In survival analysis, factors that were significantly correlated with overall survival and MCC-specific survival were N stage, M stage, liver metastasis, and lymph node surgery. CONCLUSIONS We provide epidemiological insights into Merkel cell carcinoma in elderly patients and confirmed that patients receiving lymph node surgery have better outcomes. To the best of our knowledge, this is the first study to show that the occurrence of liver metastasis is associated with poor prognosis. Our results will help strengthen monitoring of the liver condition of elderly patients and to perform necessary lymph node surgery within the patient's tolerance.

Aim: To describe the factors affecting distant metastasis of Merkel cell carcinoma (MCC) and the prognosis of metastatic MCC. Materials & methods: The MCC patient information was downloaded from the SEER database. Logistic regression and Cox proportional hazard models were conducted to screen for significant factors. Results: A total of 3449 patients were enrolled. Surgery and chemotherapy were significantly correlated with the occurrence of distant metastasis. In the cause-specific survival rate of MCC, regional lymph node removal, sentinel lymph node biopsy, radiation and chemotherapy can significantly reduce the prognostic risk of patients with distant metastases. Conclusion: Our study screened out the factors affecting the distant metastasis and prognosis of MCC and more prospective studies are needed to verify our findings.
