Umbilical Artery Embolism: A Case Report and Literature Review
Authors: Zhang Qinjian , Fang Zhuanji , Chen Siwen , Xu Xia , Yan Jianying 
Published: September 2021

Abstract
Umbilical cord (UC) embolism is a rare, life-threatening complication of pregnancy. The exact cause of this condition is not yet known. Women with more than one UC abnormality are at risk of UC obstruction; this condition can lead to stasis, ischemia, and in some cases, thrombosis. However, many women with UC abnormalities remain undetected and may not be recognized until after birth. Here, we present a case involving the prenatal diagnosis and successful treatment of umbilical artery embolism in the third trimester with good maternal and fetal outcomes. The risk of UC embolism increases when more than one UC abnormality is identified in a single case. Ultrasound examination in the third trimester of pregnancy should be able to verify the existence of two arteries and one vein in the UC. If necessary, these results can be compared with ultrasound imaging acquired during the first trimester of pregnancy.

Abstract

Objective
To build a reference fetal growth chart for the Chinese population based on fetal ultrasound measurements.

Methods
This was a multicenter, population-based retrospective cohort study. Longitudinal ultrasound measurement data were collected from 24 hospitals in 18 provinces of China from 1st September through 31st October of 2019. The estimated fetal weight (EFW) was calculated based on head circumference, abdominal circumference, and femur length using Hadlock formula 3. Fetal growth curves were estimated using a two-level linear regression model with cubic splines. All participants were divided into two groups: the northern group (n = 5829) and the southern group (n = 3246) based on the geographical division of China and male fetus group (n = 4775) and female fetus group (n = 4300) based on fetal gender. The EFW was compared by fetal gender and geographical group. All statistical models were adjusted for maternal sociodemographic characteristics.

Results
A total of 9075 participants with 31,700 ultrasound measurement records were included in this study. Male fetuses demonstrated significantly larger EFW compared to female ones starting at 16 weeks of gestation and extending to delivery (global test P < 0.01). The overall geographic difference in EFW was significant (global test P = 0.03), and week-specific comparisons showed that the northern group had a greater EFW starting at 15 weeks of gestation and extending to 29 weeks of gestation, although this difference did not extend to the time of delivery. The Z-score of EFW confirmed that our Chinese fetal growth charts differed from previously published standards.

Conclusion
This study provides EFW and ultrasound biometric reference measurements for Chinese fetuses and reveals differences from other fetal growth charts. The chart is worth promoting in more regions of China but should be tested prudently before use.
Immediate Dental Implant Placement in the Oncologic Setting: A Conceptual Framework
Authors: Anolik Rachel A. , Nelson Jonas A. , Rosen Evan B. , Disa Joseph , Matros Evan , Allen Robert J. 
Published: September 2021

Summary:
Historically, immediate dental implants have been reserved for patients with benign disease, with full dental rehabilitation rarely being accomplished in the oncologic setting due to concerns related to implant survival, flap compromise, and delay in initiation of adjuvant therapy. Recent developments in technology have made immediate dental implants using virtual surgical planning safe and reliable. At Memorial Sloan Kettering Cancer Center, we have implemented a workflow for immediate dental implant placement in the oncologic patient population that has become a routine part of maxillary and mandibular reconstruction. This approach begins with a multidisciplinary virtual surgical planning session and custom dental splints to be used for cutting and inset guides. Dental implants are placed intraoperatively at the time of tumor resection and reconstruction with the fibula flap. A temporary prosthesis, which can be worn during radiation therapy, is placed following a vestibuloplasty, approximately 4–6 weeks after the initial reconstruction. After the completion of radiation therapy and the resolution of edema, a permanent prosthesis is placed. When critically evaluating our experience, we have found that patients undergoing immediate dental implant placement have higher rates of implant survival and no delay in adjuvant therapy. The protocol described here in detail has successfully expanded the indications for immediate dental rehabilitation in the oncologic patient population.

Authors: Tresoldi Marco Mario , Ivaldi Giovanni Battista , Porcu Patrizia , Randisi Fabio , Cartocci Andrea , Malovini Alberto , Faga Angela , Nicoletti Giovanni 
Published: September 2021

Background:
The combination of surgery and postoperative radiotherapy allows for the most effective results with keloids. In this trial, surgery and intraoperative radiation therapy (IORT) technology were used—the hypothesis being that the earlier the application of postoperative radiotherapy, the better the wound healing evolution.

Methods:
The study included 16 patients with 21 keloids. The keloids were radically excised and repaired with direct suture or local skin flaps. Collimated electron radiotherapy was applied within 45 minutes of surgery. The outcomes were assessed according to the modified Patient and Observer Scar Assessment Scale; the modified Vancouver Scar Scale; and the modified Common Terminology Criteria for Adverse Events v. 4.0 for skin and subcutaneous tissue disorders.

Results:
Recurrences were observed in one out of 16 patients, and in two out of 21 keloids (9.5%). The modified Patient and Observer Scar Assessment Scale demonstrated a statistically significant improvement in pain, itching, color, stiffness, thickness, and irregularity after the treatment. The modified Patient and Observer Scar Assessment Scale displayed a statistically significant improvement in the scar vascularity, pigmentation, thickness, and pliability after the treatment. The modified Vancouver Scar Scale demonstrated a statistically significant improvement in 90.48% of the scars after the treatment. The modified Common Terminology Criteria for Adverse Events v. 4.0 for skin and subcutaneous tissue disorders demonstrated an improvement in erythema multiforme and skin pain across the whole sample, with a temporary hyperpigmentation in 19% of the scars after the treatment.

Conclusion:
The combination of surgery and collimated electron radiotherapy with IORT technology demonstrated favorable results in 90.5% of the cases.

Authors: Gelidan Adnan Ghazi , Bugis Ahad , Al-Shammari Layla , Omaish Nojoud , Al-Sharif Sadem , Al-Juhayyiam Saad , Bakraa Reem , Rustom Mohammed 
Published: September 2021

Background:
Hand injury in general and fractures in particular are among the most common complaints of hand trauma patients presenting to our emergency department. Depending on fracture types, geometry, locations, and stability, treatment options may vary from close reduction and splinting to close reduction and K-wire fixation, and finally, to open reduction and internal fixation. The aim of the study was to prove that premarking of K-wire trajectory helps reduce procedure and fluoroscopy time, as well as the number of wire-insertion attempts, and minimize bone and soft tissue injury in the management of phalangeal finger fractures.

Methods:
This is a prospective descriptive study aimed to describe a surgical technique. Patients who underwent close reduction and K-wire fixation of phalangeal digital fractures were enrolled. A total of 20 cases were included.

Results:
The total number of K-wires was 37, and the total number of successful attempts was 40; average fluoroscopy time was 22.75 seconds; and average total operative time was 14.25 minutes. Surgeries of all cases were supervised by a consultant physician, but some were performed by a junior resident in the team. The inaccuracy index was measured for the group.

Conclusions:
Marking of the trajectory before placing K-wires for the management of digital fractures is not described in the literature. Our study describes an innovative operative technique that, when combined with the classic K-wire fixation technique, produces beneficial outcomes in the form of reduction in operative time and number of wire introduction attempts, with overall reduction in fluoroscopy time and soft tissue and bone damage (including false passages).
Operating Room Stencil: A Novel Mobile Application for Surgical Planning
Authors: Sayadi Lohrasb R. , Chopan Mustafa , Sayadi Jamasb J. , Samai Aubtin , Arora Jagmeet S. , Anand Suraj , Evans Gregory , Widgerow Alan D. , Vyas Raj 
Published: September 2021

Summary:
The techniques used to make preoperative markings before soft tissue reconstruction have remained relatively unchanged since the earliest years of plastic surgery. Using skin-marking pens, many surgeons continue to draw markings freehand as “best estimates” before their first incisions. Although efficient for the experienced surgeon, this strategy may prove challenging for residents and trainees striving to learn and maintain consistency while replicating the intricate geometries of flap markings. To address this need, Operating Room Stencil was developed as a novel tool for digitally planning flap markings that may then be projected onto contoured surfaces such as the human body. As a cost-free mobile application, Operating Room Stencil is widely accessible to the medical community and offers educational captions for a majority of the flaps featured in its database. Users can plot relaxed skin tension lines onto uploaded facial images, thus enabling surgeons to orient surgical markings in a way that optimizes scar formation and reduces wound contraction. Although originally intended to appeal to trainees as a reliable way to learn about flaps and practice their technique, Operating Room Stencil may prove useful even among more experienced surgeons striving to further perfect their visualization and execution of flap markings.

Authors: Kongpanichakul Laliphat , Chuangsuwanich Apirag , Kongkunnavat Natthapong , Tonaree Warangkana 
Published: September 2021

Background:
Plasma, the fourth state of matter, has been widely proposed in antiaging medicine. The usage of low-temperature plasma (LTP), which converts nitrogen gas into plasma, demonstrates releasing of several growth factors and promotion of tissue regeneration. The nonchromophore-dependent property and preservation of skin architecture after treatment make LTP an interesting tool for facial rejuvenation. This study aimed to investigate the efficacy of LTP for facial rejuvenation.

Methods:
A prospective cohort study involving 40 women who received full face LTP treatment once a week for 5 consecutive sessions. The melanin index, erythema index, and elasticity index were measured by Mexameter and Cutometer, respectively. The Fitzpatrick wrinkle scale and quartile grading scale were assessed by two plastic surgeons.

Results:
All patients were between 26 and 55 years old and had mild-to-moderate Fitzpatrick wrinkle scale scores. The Fitzpatrick wrinkle scale scores showed a mean improvement of 0.47 and 0.89 at 4 and 12 weeks posttreatment (P < 0.001). Statistically significant improvements in melanin index, erythema index, and elasticity index at periorbital and perioral areas were found at 4 and 12 weeks after treatment (P < 0.001). Most subjects had quartile grading scale improvement of 51%–75% at 4 and 12 weeks after treatment. Patients reported a greater than 75% improvement in dyspigmentation, wrinkles, and elasticity in 60%, 50%, and 57.5% of subjects, respectively.

Conclusion:
LTP is another choice for facial rejuvenation, wrinkles reduction, and dyspigmentation with significantly improved results.
Head and Neck Reconstruction with Venous Flap: A Case Report
Authors: Abtahi Ali R. , Coyne Catherine , Odobescu Andrei 
Published: September 2021

Summary:
Venous flaps are nonphysiologic flaps in which the venous system replaces the vascular circuit found in conventional flaps, serving as inflow as well as outflow. Although a main concern with venous flaps has been their reliability, this can be improved by manipulating their physiology using shunt restriction. The soft, pliable tissue provided by venous flaps coupled with the low donor site morbidity and ease of flap harvest make them ideal for coverage of moderate-sized facial defects, which may be too large for local options yet too small for conventional free flaps. We report the use of a large, 70 cm2 arterialized venous free flap to reconstruct a complex forehead deficit after basal cell carcinoma resection. Furthermore, we present the first report of the successful use of valvulotomes in the case of a large, reverse flow arterialized venous flap where several in-series valves were found to prevent adequate perfusion of the flap. Upon removal of the valves, complete perfusion of the flap was achieved.
Facial Thread Lifting Complications in China: Analysis and Treatment
Authors: Li Yi-Lin , Li Ze-Hui , Chen Xue-Ying , Xing Wen-Shan , Hu Jin-Tian 
Published: September 2021

Background:
Facial thread lifting technology has been applied for more than 30 years, with relatively few complications. In 2014, China approved polydioxanone thread (an absorbable barbed thread) for large-scale nonsurgical facial lifting. However, due to surgeons’ lack of overall experience, the complications of polydioxanone thread facelift have been relatively high.

Methods:
From April 2014 to January 2020, a total of 190 patients with postoperative complications of facelifts were treated after they underwent thread lifting in other hospitals. Of these, 189 patients were women and one was a man; the age of patients ranged from 28 to 62 years, with an average age of 37.4 years.

Results:
Patients were mainly treated in our outpatient clinic for the following complications: skin dimpling (77 cases, 40.5%); contour irregularity (32 cases, 16.8%); visible threads (31 cases, 16.3%); thread extrusion (10 cases, 5.3%); infection (17 cases, 8.9%); swelling (nine cases, 4.7%); incomplete facial paralysis (five cases, 2.6%); hyperpigmentation (four cases, 2.1%); hematoma (four cases, 2.1%); allergy (one case, 0.05%). Follow-up was scheduled 1–24 weeks after treatment.

Conclusions:
The most common complications of facial thread lifting are, in the following order, skin dimpling, contour irregularity, visible threads, and thread extrusion. The reasons for complications are mainly unfamiliarity with facial anatomy, unskilled surgical operation, and misunderstanding of the facial aesthetics of Asian women.
Discrepancies between Conference Abstracts and Published Manuscripts in Plastic Surgery Studies: A Retrospective Review
Authors: Dagi Alexander F. , Parry Gareth J. , Labow Brian I. , Taghinia Amir H. 
Published: September 2021

Background:
Inconsistency in results and outcomes between presented abstracts and corresponding published articles can negatively affect clinical education and care. The objective of this study was to describe the frequency of clinically meaningful change in results and outcomes between abstracts presented at the American Association of Plastic Surgeons annual conference and the corresponding published articles, and to determine risk factors associated with discrepancies.

Methods:
All abstracts delivered as oral presentations at the American Association of Plastic Surgeons conference (2006–2016) were reviewed. Results and outcomes were compared with those in corresponding articles. We defined clinically meaningful discrepancy as any change in the directionality of an outcome, or a quantitative change in results exceeding 10%.

Results:
Four hundred eighty-six abstracts were identified. Of these, 63% (N = 305) advanced to publication. Of the published studies, 19% (N = 59) contained a discrepancy. In 85% of these (N = 50), discrepancies could not be explained by random variation. Changes in sample size were associated with heightened risk for a discrepancy (OR 10.38, 95% CI 5.16–20.86, P < 0.001). A decrease in sample size greater than 10% increased the likelihood of a discrepancy by 25-fold (OR 24.92, 95% CI 8.66–71.68, P < 0.001), whereas an increase in sample size greater than 10% increased the likelihood of a discrepancy by eight-fold (OR 8.36, CI 3.69–19.00, P < 0.001).

Conclusions:
Most discrepancies between abstract and published article were not due to random statistical variation. To mitigate the possible impact of unreliable abstracts, we recommend abstracts be marked as preliminary, that authors indicate whether sample size is final at time of presentation, and that changes to previously reported results be indicated in final publications.
Perceived Role Responsibilities Among Physical Therapists and Orthotists
Authors: Kenworthy Sally , Reno Ariel , Reid Andrew 
Published: September 2021

ABSTRACT

Introduction
The provision of orthoses is a specialized practice within healthcare that requires collaboration among professionals for successful treatment outcomes. Although orthotists are an integral part of the process, the role of the orthotists may not be commonly understood or appreciated. Among the rehabilitative health care team, physical therapists (PTs) and orthotists are especially aligned, with overlapping roles in each profession's scope of practice.

Materials and Methods
A cross-sectional survey was distributed to members of the health care team, including certified prosthetist orthotists and PTs. Chi-squared tests were calculated to compare PT and orthotist responses to a question regarding role responsibilities of each team member. We hypothesized that there would be disagreement among the professions as to which tasks orthotists are responsible for performing.

Results
The results of this study suggest that PTs and orthotists agree that orthotists are responsible for recommending a patient-specific orthosis. Interestingly, PTs did not identify orthotists as a team member responsible for performing patient assessment and evaluation tasks, despite these tasks being a key driver of patient-specific orthosis recommendations.

Conclusions
Interprofessional education to increase knowledge of orthotic management principles among PTs may improve collaboration and communication within the health care team.

Clinical Relevance
The present study identified a potential gap in PT awareness of the scope of practice and training of certified orthotists. Provision of optimal patient management requires clear understanding of respective roles and responsibilities of the health care team.
Exploring Factors Related to Job Satisfaction Among Junior Faculty in US Physical Therapist Education Programs
Authors: Varnado Kimberly E. , Bierwas Debra A. , Alexander Jeffrey L. 
Published: September 2021

Introduction.
Physical therapists (PTs) from various educational and clinical backgrounds are being hired to address the faculty shortage issue. Little is known about how junior PT faculty feel about their experiences in academia. The purpose of this study was to 1) explore current demographic and self-perceived experiences of junior faculty in PT education programs across the United States, 2) compare beliefs and experiences based on the highest academic degree held and the type of faculty line held, and 3) explore the relationships between job satisfaction and experiences in academia with the likelihood to remain in academia. Full-time junior faculty employed 5 years or less at accredited PT education programs.

Methods:
Descriptive correlational study using a 63-item, self-report, electronic, job satisfaction survey was sent to faculty employed at 223 accredited PT education programs in the United States.

Results:
Two hundred twenty-four full-time junior faculty completed the survey. Respondents with clinical degrees were more satisfied in their position and more likely to stay in academia than those with terminal academic degrees. Similarly, respondents in nontenure-track positions were more satisfied and more likely to stay in academia than those in tenure-track positions. Social support, teaching, and scholarly activity mentorship were found to contribute to job satisfaction. Also, an association was found between job satisfaction and intention to remain in academia for all cohorts (r

s
≥ 0.72; P = .001).

Discussion and Conclusions:
Junior PT faculty who received support and mentorship were more satisfied with their jobs and more likely to remain in academia. PT education programs should consider new or expanded mentorship programs for junior faculty, regardless of academic background, to promote professional progress, positive role-modeling, and faculty retention.

Published: September 2021

Abstract

Background:
Although the incidence of acute myocardial infarction (AMI) is decreasing, the mortality in AMI patients remains substantial. Traditional Chinese medicine has shown its role in the prevention and management of AMI. The purpose of this study is to evaluate the clinical efficacy of Xuesaitong injection (XST) for the treatment of AMI by a meta-analysis.

Methods:
A literature search was performed in 5 medical databases up to June 1, 2020. Randomized controlled trials involving XST combined with conventional treatment versus conventional treatment were included. A meta-analysis of clinical efficacy, left ventricular function and other objective parameters was performed to evaluate the effects of XST on AMI.

Results:
Five randomized controlled trials involving 539 participants were eventually included. Meta-analysis showed that the combination of XST and conventional treatment could achieve significantly better effect on improving clinical efficacy (risk ratio: 1.09 [1.01, 1.17]; P = .04), left ventricular ejection fraction (mean difference [MD]: 3.18 [1.69, 4.67]; P < .0001), hypersensitive C-reactive protein (MD: −2.58 [−5.04, −0.12]; P = .04), interleukin 6 (MD: −26.00 [−38.85, −13.16]; P < .0001), cardiac troponin T (MD: −15.85 [−18.09, −13.61]; P < .00001) and creatine kinase myocardial isoenzyme (MD: −73.06 [−79.74, −66.37]; P < .00001).

Conclusion:
XST combined with conventional treatment can achieve better efficacy on clinical performance and some of the AMI related parameters. However the interpretation of the results should be cautious, due to the relatively low quality of included trials. More rigorously designed, large-scaled, randomized controlled trials are warranted to support its clinical use in the future.
