AbstractBackgroundThe temporal lifting technique can provide lateral facial lifting when administering hyaluronic acid (HA)‐based soft tissue fillers into the subdermal plane of the temple. However, the central facial oval is not influenced by this technique.ObjectivesTo identify the safety and esthetic effectiveness of additional midfacial injection points (in addition to the temporal lifting technique) that can volumize the medial midface, lift the lateral face, and increase jawline contouring when included into a full‐face injection algorithm.MethodsThe patient records of nine consecutive patients (all females) with a mean age of 35.0 (8.4) years and a mean body mass index of 21.7 (2.4) kg/m2 were retrospectively analyzed after a full‐face injection algorithm was performed using HA‐based fillers. The additional injection points target the supraperiosteal plane of the medial zygomatic arch, the lateral infraorbital region, and the pyriform fossa using both needles and cannula.ResultsNo adverse events were observed during the 6‐month retrospective observational period. The volume of the medial midface increased, the volume of the lateral midface decreased, and the contour of the jawline improved; all effects reached a highly statistically significant level with p < 0.001.ConclusionDespite each individual injection is currently performed on a daily clinical basis the evaluated injection algorithm following the temporal lifting technique shows some evidence that it is safe and esthetically effective. Future studies will need to confirm the results presented herein in a larger sample and with objective outcome measures to guide safe and effective esthetic outcomes.

Background: Between 1984 and 1994, a single surgeon performed 132 primary cementless total ankle replacements using the Agility total arthroplasty system. The purpose of this study was to report on the 20-year follow-up, which we believe is the first study with this length of follow-up. Methods: Living patients were contacted and interviewed to determine the status of their implant (revised or unrevised) and to answer a simple questionnaire concerning overall satisfaction, pain, and functional improvement, as in a previous study. Thirty-three (26.2%) patients with 33 (25%) ankles of the original series were alive at a minimum of 20 years postoperatively, with a median follow-up of 22 years. They were asked to return to the office for standing anteroposterior and lateral ankle and foot radiographs or to send these radiographs if performed elsewhere. Radiographs were evaluated for radiolucencies around the components and subsidence (talar component) or migration (tibial component) of components. Results: Seventeen (13.5%) ankles of the 126 available for follow-up, including 5 (15.2%) ankles in living patients, had undergone revision ( n = 10) or arthrodesis ( n = 7) for loosening. One additional ankle was revised for infection and 1 for talar component malposition; thus, 19 (15.1%) ankles were revised. Conclusion: These results should provide a 20-year benchmark for newer total ankle arthroplasty designs when a similar length of follow-up becomes available. Level of Evidence: Level III, retrospective cohort study.

ABSTRACT Introduction: The impact of albumin resuscitation on sepsis outcomes is debated, particularly in the initial phase of resuscitation. We aimed to investigate the association between albumin use in the initial 6 h of resuscitation and subsequent outcomes in adult septic patients. Methods: This single-center, retrospective, propensity score-matched cohort study included adult patients admitted to intensive care units (ICUs) with sepsis or septic shock from January 1, 2006, to May 4, 2018, at a tertiary referral hospital. We compared two groups based on albumin receipt within the initial six resuscitation hours (albumin group vs. non-albumin group). We performed a 1:2 propensity score matching to assess shock-free time in ICU as the primary outcome. Results: Of 2,732 patients with medical sepsis, 286 cases in the albumin group were matched with 549 individuals in the non-albumin group. Compared to the non-albumin group, the albumin group required more intravenous fluids and had higher net fluid balance, lower mean arterial pressure, and lower serum base excess level in the initial 6 and 24 h of resuscitation. Shock-free time, ICU and hospital length of stay, and 28-day mortality were not different between albumin and non-albumin groups (56 vs. 66 h, P = 0.18; 3.5 days vs. 3.7 days, P = 0.61; 9.1 days vs. 9.5 days, P = 0.27; 36% vs. 32%, P = 0.25, respectively). Conclusions: Using albumin during the initial 6 h of resuscitation was not associated with benefits in clinical outcomes of patients with medical sepsis.

The optimal training of the highly specialized congenital heart surgeon is a long and complex process, which is a significant challenge in most parts of the world. The World Society for Pediatric and Congenital Heart Surgery (WSPCHS) has established the Global Council on Education for Congenital Heart Surgery as a nonprofit organization with the goal of assessing current training and certification and ultimately establishing standardized criteria for the training, evaluation, and certification of congenital heart surgeons around the world. The Global Council and the WSPCHS have reviewed the present status of training and certification for congenital cardiac surgery around the world. There is currently lack of consensus and standardized criteria for training in congenital heart surgery, with significant disparity between continents and countries. This represents significant obstacles to international job mobility of competent congenital heart surgeons and to the efforts to improve the quality of care for patients with Congenital Heart Disease worldwide. The purpose of this article is to summarize and document the present state of training and certification in congenital heart surgery around the world.

Abstract Background Facial aging is a multifactorial process that involves all tissues of the face, including skin, muscles, fat, ligaments, and bone. Whereas robust evidence is available for age-related changes of bone and facial fat, the influence of age on facial muscle activity is poorly understood. Objectives The objective of this study was to investigate the motor unit action potential of facial muscles by utilizing surface-derived, noninvasive electromyography in young and old healthy volunteers. Methods The study investigated a total of 32 healthy volunteers with a mean [standard deviation] age of 42.6 [19.6] years (range, 21-82 years) and a mean BMI of 23.9 [2.7] kg/m2 (range, 18.5-29.7 kg/m2) by performing surface-derived, noninvasive facial electromyography. Nine facial muscles were investigated bilaterally, resulting in a total of 1632 measurements of the signal, baseline noise, and signal-to-noise ratio of these muscles. Results The results of the study revealed that age does not significantly influence the signal (P = 0.234), the baseline noise (P = 0.225), or the signal-to-noise ratio (P = 0.432) of younger individuals (&lt;30 years) vs older individuals (&gt;50 years) in a gender- and BMI-matched statistical model. Exceptions were the zygomaticus major muscle (reduced activity), procerus muscle (increased activity), and corrugator supercilii muscle (increased activity). Conclusions The results of this facial electromyography study may help to increase the understanding of facial aging. Future studies need to reproduce the results presented herein to further increase our understanding of facial aging.

Abstract Background Injectable soft tissue fillers are used on a global scale for a variety of aesthetic indications. Despite their widespread use, there is a dearth of information regarding needle deformation following injection procedures. Repeated injections with the same needle could lead to progressive needle tip deformation, potentially resulting in decreased precision and increased patient discomfort. Objectives The objective of this study was to quantify the magnitude of needle tip deformation utilizing scanning electron microscopy (SEM) image analysis. Methods An observational study was performed evaluating 4 differently sized needles following soft tissue filler injections for 5 different aesthetic indications (zygomatic arch, infraorbital, midcheek, nasolabial sulcus, and perioral) in patients aged 36 to 64 years. Following treatment, each needle was visualized and imaged through SEM, and the percentage of deformation in relation to the total amount of needle tip surface was calculated. Results The factor most influencing needle tip damage was revealed to be the number of injection passes, ie, dermal transitions. Per injection procedure, an increase in needle tip damage of 4.7% occurred. Touching the bone deformed the needle tip by 9.6% and an increase in needle size resulted in 0.13% more damage. Conclusions To the authors’ knowledge, this is the first SEM investigation to provide objective evidence for the deformation of needle tips after repeated facial soft tissue filler injections. These data may help improve patient safety and comfort during these minimally invasive procedures. Level of Evidence: 3
