Evaluating Quality of Life After Facial Reanimation Using the Facial Clinimetric Evaluation Scale in a Series of Pediatric Patients.

BACKGROUND: Facial palsy can have significant functional and psychological impact. Dynamic facial reanimation methods have provided means of restoration of smile. There remains a dearth of quality of life data in children. The authors aim to assess patient reported outcomes in this underreported population. METHODS: A retrospective review was performed of pediatric patients with facial palsy who had dynamic facial reanimation from 2009 to 2017 at a single institution. Patients were sent a digital Facial Clinimetric Evaluation (FaCE) questionnaire, a validated tool to assess patient quality of life. FaCE statements are grouped into 6 categories: facial movement, facial comfort, oral function, eye comfort, lacrimal control, and social control. RESULTS: Twenty patients met inclusion criteria. Fourteen successfully completed the survey. With normal function being 100, our cohort scored: facial movement 38.7 ±â€Š14.3; facial comfort 67.3 ±â€Š23, oral function 75 ±â€Š22.7, eye comfort 68.75 ±â€Š18.2, lacrimal control 53.6 ±â€Š32.5, social function 64.3 ±â€Š25.6. The overall FaCE score was 61.07 ±â€Š10.85. The facial movement subscores were lower for brow raise 16.1 ±â€Š33.4 relative to smiling 53.6 ±â€Š29.2 and lip pucker, 46.4 ±â€Š23.7. No correlation was found between facial movement scores and total scores (R2 < 0.01). There was a strong negative correlation between total scores and time since procedure (Spearman's rho R =  -0.45). CONCLUSION: Our pediatric facial reanimation cohort demonstrated excellent social function, in contrast to a relatively lower facial movement score. The low facial movement score was mediated by low score for brow raise and was not correlated to overall FaCE score. Interestingly, overall FaCE score tended to decrease with time from procedure.

The limited incision harvest of the rectus femoris flap for complex groin wound management.

BACKGROUND: Muscle flaps can be effective in the protocol of complex groin wound management, yet donor-site morbidity remains a continued concern. The purpose of this study was to present a minimally invasive approach to the harvest of the rectus femoris flap (RFF) for groin wound vascularized tissue coverage. PATIENTS AND METHODS: A retrospective study examined all patients undergoing RFF coverage and reconstruction of a complex groin wound between July 1, 2010, and December 31, 2011. During the study period, the senior author (S.K.K.) performed all RFF harvests through a minimally invasive approach, whereas all other surgeons performed the RFF harvest through a standard approach. Patients who underwent a minimally invasive RFF approach were compared with those who underwent the standard incision. RESULTS: Forty-three patients underwent RFF coverage procedures, 11 of which were carried out using the minimally invasive technique. The patients in the minimally invasive cohort were older (P = 0.03) but had similar rates of medical comorbidities. Minimally invasive RFF harvests were more commonly performed in the planned, salvage setting (P = 0.03). No difference was found in the vascular surgery procedure type (P = 0.13), presence of exposed prosthetic graft material (0.2), or rate of culture-positive wound (P = 0.67). Importantly, no differences in operative time (184.4 [45.5] minutes vs 169.3 [31.7] minutes, P = 0.45) or postoperative complications were observed, with no graft losses or major limb-related morbidity in either group. CONCLUSIONS: The RFF continues to be a workhorse flap for complex groin wounds, most often in the salvage setting. This study demonstrates that a minimally invasive approach can be used for flap harvest with equivalent results to that of the standard longitudinal incision.

Genetic structure, behaviour and invasion history of the Argentine ant supercolony in Australia.

Biological invasions have significant ecological, evolutionary and economic consequences. Ants are exemplary invaders and their invasion success is frequently attributed to a shift in social structure between native and introduced populations. Here, we use a multidisciplinary approach to determine the social structure, origin and expansion of the invasive Argentine ant, Linepithema humile, in Australia by linking behavioural and genetic studies with indicators of dispersal pathways and propagule pressure. Behavioural assays revealed a complete absence of aggression within and between three cities - Melbourne, Adelaide and Perth - spanning 2700 km across Australia. Microsatellite analyses showed intracity genetic homogeneity and limited but significant intercity genetic differentiation. Exceptions were two Perth nests that likely represent independent translocations from Adelaide. These patterns suggest efficient local gene flow with more limited jump dispersal via transport corridors between cities. Microsatellite analyses of L. humile from potential source regions, combined with data from port interceptions, trade pathways and the timeline of spread within Australia, implicate the main European supercolony as the source of L. humile in Melbourne. Such an introduction probably then redistributed across Australia and spread to New Zealand to form an expansive Australasian supercolony.
