Abstract Skin substitutes are considered a useful alternative for occlusive dressings in the treatment of superficial burns as they reduce the frequency of dressing replacement. This phase II randomized controlled trial aimed to evaluate the efficacy of Nile tilapia (Oreochromis niloticus) skin as an occlusive xenograft dressing for the treatment of burn wounds in humans. In order to assess the use of tilapia skin, the following variables were evaluated: number of days for wound healing, the number of times the occlusive dressing was changed, use of anesthetics or analgesics, pain assessment using the Visual Analogue Scale, and evaluation of burn improvement on the day of dressing removal. In total, 62 participants completed the study. It was found that in participants treated with tilapia skin, complete reepithelialization occurred in significantly fewer days; reported pain intensity was lower (study arms B and C), the amount of anesthetics/analgesics required was lower (study arms B and C), and the necessity of dressing changes was significantly reduced in comparison with volunteers treated with silver sulfadiazine. In our study, the tilapia skin xenograft showed good efficacy as an occlusive biological dressing for burn wound treatment in humans.

Background Microsurgery is one of the most complex operative skills. Recent restrictions on residents’ working hours challenge residency program directors to ensure skill acquisition with scant time dedicated to microsurgery practice. We aimed to summarize the contribution of plastic surgery journals in microsurgical education. Methods A comprehensive literature search was performed. Results We observed an increasing number of publications on microsurgery education over the years. This could be due to the adoption of new technologies developed in the last 2 decades, the concerns about quality of resident training in the context of reduced work hours, the well-described benefit of medical simulations in other specialties, and the pressure on trainees to be proficient before operating on patients. The variety of aspects addressed in plastic surgery publications is broad: simulators, courses, skills assessment, national surveys, and technology trends. Conclusion There is an upward trend in the number of publications and plastic surgery journals, demonstrating a remarkable contribution to microsurgery training.

Background: Based on an established classification system of Apert syndrome subtypes, detailed regional morphology and volume analysis may be useful to provide additional clarification to individual Apert cranial structure characteristics, and treatment planning. Methods: Computed tomography scans of 32 unoperated Apert syndrome and 50 controls were included and subgrouped as: type I, bilateral coronal synostosis; type II, pansynostosis; type III, perpendicular combination synostosis. Three-dimensional analysis of craniometric points was used to define structural components using Materialise Mimics and 3-Matics software. Results: Occipitofrontal circumference of all subtypes of Apert syndrome patients is normal. Intracranial volumes of types I and II were normal, but type III was 20% greater than controls. Middle cranial fossa volume was increased in all 3 types, with the greatest increase in type II (86%). Type II developed a 69% increase in anterior cranial fossa volume, whereas type III had 39% greater posterior cranial fossa volume. Increased cranial fossa depth contributed most to above increased volume. The anteroposterior lengths of middle and posterior cranial fossae were reduced in type I (15% and 17%, respectively). However, only the anterior cranial fossa was significantly shortened in type III. Conclusions: Occipitofrontal circumference and overall intracranial volume is not always consistent in individual subunits of Apert syndrome. Detailed and segmental anterior, middle, and posterior cranial fossae volumes and morphology should be analyzed to see what impact this may have related to surgical planning.

Background Primary leiomyoma is a rare cause of a mass in the hand, with few reported cases to date. To our knowledge, this constitutes the most comprehensive and up-to-date systematic review of the literature of all cases of primary hand leiomyoma. We also provide an additional case recently managed in our practice of confirmed primary vascular leiomyoma of the hand in a 44-year-old woman to add to the current body of literature. Methods We performed a comprehensive literature review of all articles published on primary leiomyoma of the hand. The PubMed database was used, with search terms leiomyoma hand, angioleiomyoma hand, and angiomyoma hand. Articles were selected for their accuracy in anatomic localization in the hand and confirmed pathology of leiomyoma. Results Our initial search query resulted in 216 articles. After applying the inclusion criteria, we identified 50 individual articles with 108 cases of confirmed primary leiomyoma in the hand from January 1, 1954, to July 1, 2018. Common initial clinical impressions recorded for primary hand leiomyoma included ganglion cyst, giant-cell tumor, hemangioma, and glomus tumor. Patients presenting with leiomyoma of the hand frequently describe a painful lesion, which differs from most other benign tumors of the hand at presentation. Conclusions Leiomyoma is an important consideration when developing a differential diagnosis for primary benign masses in the hand. We hope that this comprehensive review can provide increased awareness of this tumor type.

Background: Latissimus dorsi myocutaneous flap (LDMF) with tissue expander provides excellent results in breast reconstruction. Acellular dermal matrix (ADM) has been used in expander-based reconstruction (EBR) with good results. This study assesses how ADM compares to LDMF in EBR. Methods: The cohorts comprised 124 patients (218 breasts) who had EBR using ADM between 2006 and 2012, and 242 patients (266 breasts) who had EBR using LDMF between 1994 and 2012. Postoperative complications, reoperations, Breast-Q scores, and objectively assessed aesthetic outcomes were compared. Results: Median age was 55 years for both ADM (range 23–84) and LDMF (range 26–88) groups. No statistically significant differences were noted between the groups in the rates of major postoperative complications (P > 0.3). Forty-nine of the 218 (22.5%) in the ADM group and 67 of 266 (25.2%) in the LDMF group had a total of 63 and 84 reoperations, respectively (P = 0.52), with no significant differences in the reoperations rate (P > 0.3). No significant differences were observed in the Breast-Q scores. Some categorical differences were noted in the aesthetic outcomes; however, the difference between the overall outcomes was not significant (P = 0.54). Conclusion: Our study revealed no statistically significant differences in the complications or reoperation rates, patient satisfaction, or overall aesthetic outcomes when comparing the use of ADM to LDMF in EBR. In conclusion, this study supports the hypothesis that ADM performs as well as LDMF in EBR.
