Complete Hemifacial Paralysis Post-facelift: Making Sense of a Plastic Surgeon's Worst Nightmare.

BACKGROUND: Postrhytidectomy hemifacial paralysis is a frightening clinical condition affecting the proximal facial nerve and most often associated with Bell's palsy. Associated symptoms are common and include auditory, salivary, vestibular, and gustatory complaints. OBJECTIVES: The aim of the study was to provide increased awareness of postrhytidectomy hemifacial paralysis secondary to Bell's palsy in the plastic surgery community. METHODS: Following a roundtable discussion with the senior author's (J.C.G.) plastic surgery colleagues located all over the world, 8 surgeons reported having had firsthand experience with hemifacial paralysis in patients following facelift. Descriptions of their cases, including preoperative, intraoperative, and postoperative courses were collected and reported. RESULTS: A total of 10 cases of postrhytidectomy hemifacial paralysis were analyzed based on results of a clinical questionnaire. Eight of the 10 cases involved all facial nerve branches, with 2 cases sparing the marginal mandibular branch. The vast majority of cases were referred to a neurologist and steroids initiated. Two patients were returned to the operating room for exploration. Associated symptoms reported included pain in the ear, hearing loss, ocular symptoms such as tearing or dryness, vestibular symptoms such as vertigo, changes in taste, and in 1 patient an electric-shock type sensation to the face. CONCLUSIONS: Hemifacial paralysis associated with Bell's palsy following rhytidectomy is a rare but known clinical entity that should be included in the preoperative informed consent process before facelift. Current management trends are neurology referral and steroid initiation.

NT-Pro BNP Predicts Myocardial Injury Post-vascular Surgery and is Reduced with CoQ10: A Randomized Double-Blind Trial.

BACKGROUND: NT-Pro BNP levels provide incremental value in perioperative risk assessment prior to major noncardiac surgery. Whether they can be pharmacologically modified in patients prior to an elective vascular operation is uncertain. METHODS: A double-blind, randomized controlled trial was implemented at a single institution. Patients were screened during their preoperative vascular clinic appointment and randomly assigned to CoQ10 (400 mg per day) versus Placebo for 3 days prior to surgery. Biomarkers, including NT-Pro BNP, troponin I and C-reactive protein were obtained prior to and following surgery for up to 48 hours. The primary endpoint was postoperative NT-Pro BNP levels, and secondary endpoint measures included myocardial injury, defined by an elevated cardiac troponin level and length of stay. RESULTS: One hundred and twenty-three patients were randomized to receive either CoQ10 (N = 62) versus Placebo (N = 61) for 3 days before vascular surgery. Preoperative cardiac risks included ischemic heart disease (N = 52), CHF (N = 12), stroke (N = 23), and diabetes mellitus (N = 48) and the planned vascular procedures were infrainguinal (N = 78), carotid (N = 36), and intraabdominal (N = 9). There were no intergroup differences in these clinical variables. NT-Pro BNP levels (median; IQs) in the CoQ10 and Placebo groups were 179 (75-347) and 217 (109-585) pg/ml, respectively, (P = 0.08) preoperatively, and 397 (211-686) and 591 (288-1,433) pg/ml respectively, (P = 0.01) at 24 hours following surgery. Patients with an elevated NT-Pro BNP had a higher incidence of myocardial injury, (58% vs. 20%; P < 0.01) and a longer hospital stay (4.4 ± 3.8 vs. 2.8 ± 3.2 days; P < 0.02) compared with individuals without an elevated NT-Pro BNP level. CONCLUSIONS: NT-Pro BNP levels predict adverse events post-vascular surgery and are lowered in those patients assigned to preoperative administration of CoQ10. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT03956017. Among patients undergoing elective vascular surgery, 123 patients were randomized to either CoQ10 (400 mg/day) versus placebo for three days preoperatively. NT-Pro BNP levels (median; IQs) in the CoQ10 and Placebo groups were 179 (75-347) and 217 (109-585) pg/ml, respectively, (P = 0.08) preoperatively, and 397 (211-686) and 591 (288-1,433) pg/ml, respectively, (P = 0.01) post-surgery. Patients with an elevated NT-Pro BNP had a higher incidence of myocardial injury (58% vs. 20%; P < 0.01) and a longer hospital stay (4.4 ± 3.8 vs. 2.8 ± 3.2 days; P < 0.02) compared with individuals without an NT-Pro BNP elevation. In conclusion, BNP predicts adverse outcomes and can be reduced with preoperative CoQ10.

Arf6 and Rab22 mediate T cell conjugate formation by regulating clathrin-independent endosomal membrane trafficking.

Endosomal trafficking can influence the composition of the plasma membrane and the ability of cells to polarize their membranes. Here, we examined whether trafficking through clathrin-independent endocytosis (CIE) affects the ability of T cells to form a cell-cell conjugate with antigen-presenting cells (APCs). We show that CIE occurs in both the Jurkat T cell line and primary human T cells. In Jurkat cells, the activities of two guanine nucleotide binding proteins, Arf6 and Rab22 (also known as Rab22a), influence CIE and conjugate formation. Expression of the constitutively active form of Arf6, Arf6Q67L, inhibits CIE and conjugate formation, and results in the accumulation of vacuoles containing lymphocyte function-associated antigen 1 (LFA-1) and CD4, molecules important for T cell interaction with the APC. Moreover, expression of the GTP-binding defective mutant of Rab22, Rab22S19N, inhibits CIE and conjugate formation, suggesting that Rab22 function is required for these activities. Furthermore, Jurkat cells expressing Rab22S19N were impaired in spreading onto coverslips coated with T cell receptor-activating antibodies. These observations support a role for CIE, Arf6 and Rab22 in conjugate formation between T cells and APCs.

AeroForm patient controlled tissue expansion and saline tissue expansion for breast reconstruction: a randomized controlled trial.

BACKGROUND: Prosthetic reconstruction of the breast, as a 2-staged procedure using tissue expanders followed by placement of permanent implants, offers favorable aesthetic results with minimal additional surgical intervention. However, the current outpatient process to fill saline expanders can be lengthy and onerous, involving months of office visits and discomfort from the bolus saline expansions. We present a new technology (AeroForm Tissue Expansion System), which has the potential to improve the process of breast tissue expansion by providing a method for low-volume incremental filling, eliminating the need for injections and directly involving the patient by allowing her some control over the expansion process. METHODS: The described study is a 2:1 randomized controlled trial of the investigational CO2 expansion system and saline expanders. Of the 82 women receiving expanders, 58 (39 bilateral and 19 unilateral; bilateral rate, 67%) were implanted with CO2 tissue expanders and 24 subjects (15 bilateral and 9 unilateral; bilateral rate, 63%) were implanted with saline expanders. RESULTS: Preliminary validated expansion results were available for 55 women. Available mean time for active expansion in the CO2 group was 18.2 (9.2) days (median, 14.0; range, 5-39; number of expanders, 53), which was less than the mean time for active expansion in the saline group: 57.4 (33.6) days (median, 55; range, 5-137; number of expanders, 33). Available mean time from implant placement to exchange for a permanent prosthesis in the CO2 group was shorter [106.3 (42.9) days; median, 99; range, 42-237; number of expanders, 53] than for the women in the control group [151.7 (62.6) days; median, 140; range, 69-433; number of expanders, 33]. After 2 events--underexpansion (n=1) and erosion (n=1)--in the CO2 group, the internal membrane was redesigned and the expander bulk was decreased to minimize the risk of underexpansion and erosion in subsequent patients. CONCLUSIONS: Preliminary evidence indicates that the CO2-based tissue expansion system performs the same function as saline expansion devices without significantly altering the risk to the patient and that the device has the potential to make the expansion process faster and more convenient for both the patient and the physician.

Error framing effects on performance: cognitive, motivational, and affective pathways.

Our purpose was to examine whether positive error framing, that is, making errors salient and cuing individuals to see errors as useful, can benefit learning when task exploration is constrained. Recent research has demonstrated the benefits of a newer approach to training, that is, error management training, that includes the opportunity to actively explore the task and framing errors as beneficial to learning complex tasks (Keith & Frese, 2008). Other research has highlighted the important role of errors in on-the-job learning in complex domains (Hutchins, 1995). Participants (N = 168) from a large undergraduate university performed a class scheduling task. Results provided support for a hypothesized path model in which error framing influenced cognitive, motivational, and affective factors which in turn differentially affected performance quantity and quality. Within this model, error framing had significant direct effects on metacognition and self-efficacy. Our results suggest that positive error framing can have beneficial effects even when tasks cannot be structured to support extensive exploration. Whereas future research can expand our understanding of error framing effects on outcomes, results from the current study suggest that positive error framing can facilitate learning from errors in real-time performance of tasks.

Regulation of tight junction assembly and epithelial polarity by a resident protein of apical endosomes.

The establishment of tight junctions and cell polarity is an essential process in all epithelia. Endotubin is an integral membrane protein found in apical endosomes of developing epithelia when tight junctions and epithelial polarity first arise. We found that the disruption of endotubin function in cells in culture by siRNA or overexpression of the C-terminal cytoplasmic domain of endotubin causes defects in organization and function of tight junctions. We observe defects in localization of tight junction proteins, reduced transepithelial resistance, increased lanthanum penetration between cells and reduced ability of cells to form cysts in three-dimensional culture. In addition, in cells overexpressing the C-terminal domain of endotubin, we observe a delay in re-establishing the normal distribution of endosomes after calcium switch. These results suggest that endotubin regulates trafficking of polarity proteins and tight junction components out of the endosomal compartment, thereby providing a critical link between a resident protein of apical endosomes and tight junctions.

Resilience effects on student performance and well-being: the role of self-efficacy, self-set goals, and anxiety.

Universities prepare students to become contributing members to the workplace and to society. However, with rising tuition costs and other increasing time and resource demands, students face substantial adversity. Students' ability to cope with that adversity influences successful completion of academic coursework and retention in degree programs, ultimately providing a source of potential effective future employees. Previous research has demonstrated numerous direct relationships between dispositional resilience and pivotal outcomes, such as performance, life satisfaction, and subjective well-being. However, research has failed to explore underlying mechanisms through which resilience may affect these outcomes, especially in academic contexts. The purpose of the current study was to use self-regulation theory as a framework for examining the effects of students' resilience on outcomes. Using a sample of undergraduate students from a Midwestern university in the U.S. (N = 141), we proposed and tested a path model addressing self-efficacy, self-set goals, and state anxiety as mechanisms through which resilience influences performance and subjective well-being. Our results provided evidence supporting a structural model involving resilience, such that student resilience (a) has an indirect effect on performance through self-efficacy and self-set goals, (b) has an indirect effect on state anxiety through self-efficacy, and (c) accounts for unique variance in subjective well-being after controlling for state anxiety. Implications, limitations, and directions for future research are discussed.

Surgeon Gender-Related Differences in Operative Coding in Plastic Surgery.

BACKGROUND: Numerous studies in the medical and surgical literature have discussed the income gap between male and female physicians, but none has adequately accounted for the disparity. METHODS: This study was performed to determine whether gender-related billing and coding differences may be related to the income gap. A 10 percent minimum difference was set a priori as statistically significant. A cohort of 1036 candidates' 9-month case lists for the American Board of Plastic Surgery over a 5-year span (2014 to 2018) was evaluated for relationships between surgeon gender and work relative value units, coding information, major and minor cases performed, and work setting. Data were deidentified by the American Board of Plastic Surgery before evaluation. The authors hypothesized that work relative value units, average codes per case, major cases, and minor cases would be at least 10 percent higher for male than for female physicians. RESULTS: Significant differences were found between male and female surgeons in work relative value units billed, work relative value units billed per case, and the numbers of major cases performed. The average total work relative value units for male surgeons was 19.34 percent higher than for female surgeons [3253.2 (95 percent CI, 3090.5 to 3425.8) versus 2624.1 (95 percent CI, 2435.2 to 2829.6)]. Male surgeons performed 14.28 percent more major cases than female surgeons [77.6 percent (95 percent CI, 72.7 to 82.7 percent) versus 90.5 percent (95 percent CI, 86.3 to 94.9 percent); p = 0.0002]. CONCLUSIONS: The authors' findings support the hypothesis that billing and coding practices can, in part, account for income differences between male and female plastic surgeons. Potential explanations include practices focusing on larger and more complex operative cases and differences in coding practices.

American Society of Plastic Surgeons Evidence-Based Clinical Practice Guideline Revision: Reduction Mammaplasty.

SUMMARY: A multidisciplinary work group involving stakeholders from various backgrounds and societies convened to revise the guideline for reduction mammaplasty. The goal was to develop evidence-based patient care recommendations using the new American Society of Plastic Surgeons guideline methodology. The work group prioritized reviewing the evidence around the need for surgery as first-line treatment, regardless of resection weight or volume. Other factors evaluated included the need for drains, the need for postoperative oral antibiotics, risk factors that increase complications, a comparison in outcomes between the two most popular techniques (inferior and superomedial), the impact of local anesthetic on narcotic use and other nonnarcotic pain management strategies, the use of epinephrine, and the need for specimen pathology. A systematic literature review was performed, and an established appraisal process was used to rate the quality of relevant scientific research (Grading of Recommendations Assessment, Development and Evaluation methodology). Evidence-based recommendations were made and strength was determined based on the level of evidence and the assessment of benefits and harms.

The Business of Plastic Surgery: Employment Contracts.

SUMMARY: Plastic surgeons are increasingly choosing to practice as employed physicians: either in an academic position, a single-specialty or multispecialty group, or within a franchise-type business. Employment offers advantages with regard to immediate income, minimal investment in practice start-up costs, and easier access to prospective patients. Surgeons considering such employment must perform due diligence to determine whether the position offered is a good fit. Once the decision is made to offer the plastic surgeon a position, an employment contract is negotiated. It is imperative that all parties understand the provisions of the contract, so that there are no misunderstandings between the employer and employee for the duration of the term. This article introduces physician recruitment offers and employment contracting. The key components of a contract are described, and compensation options are explained. Negotiation of the contract is critical so that all aspects are understood and agreed on, and the responsibilities of all parties are delineated.

Patients' bath basins as potential sources of infection: a multicenter sampling study.

BACKGROUND: Nosocomial infections are a marked burden on the US health care system and are linked to a high number of patient deaths. OBJECTIVE: To identify and quantify bacteria in patients' bath basins and evaluate the basins as a possible reservoir for bacterial colonization and a risk factor for subsequent hospital-acquired infection. METHODS: In a prospective study at 3 acute care hospitals, 92 bath basins, including basins from 3 intensive care units, were evaluated. Sterile culture sponges were used to obtain samples from the basins. The culture sponges were sent to an outside laboratory, and qualitative and quantitative microbial tests were conducted and the results reported. RESULTS: Some form of bacteria grew in 98% of the samples (90 sponges), either by plating or on enrichment (95% confidence interval, 92%-99.7%). The organisms with the highest positive rates of growth on enrichment were enterococci (54%), gram-negative organisms (32%), Staphylococcus aureus (23%), vancomycin-resistant enterococci (13%), methicillin-resistant S aureus (8%), Pseudomonas aeruginosa (5%), Candida albicans (3%), and Escherichia coli (2%). Mean plate counts, in colony-forming units, were 10 187 for gram-negative organisms, 99 for E coli, 30 for P aeruginosa, 86 for S aureus, 207 for enterococci, and 31 for vancomycin-resistant enterococci. CONCLUSIONS: Bath basins are a reservoir for bacteria and may be a source of transmission of hospital-acquired infections. Increased awareness of bath basins as a possible source of transmission of hospital-acquired infections is needed, particularly for high-risk patients.

An Analysis of Differences in the Number of Children for Female and Male Plastic Surgeons.

BACKGROUND: Historically, the structure of surgical programs discourages women interested in both surgery and motherhood from pursuing a surgical career, and women plastic surgeons have been more likely than men to have no children or to have fewer, later in life. Female plastic surgery trainees now constitute over one-third of residents, and pregnancy rates can be expected to rise, but with women now a majority in medical schools, the specialty's maternity policies may be deterring interested women from entering the specialty. A survey study was conducted to measure reproductive outcomes and to identify current disparities between women and men plastic surgeons. METHODS: An anonymous electronic survey was distributed to American Society of Plastic Surgeons members and candidates, allowing comparisons of men's and women's responses. Differences were tested by the Fisher's exact and chi-square tests. RESULTS: Compared with male respondents, women were more likely than men to have no biological children (45.1 percent versus 23.1 percent). They were nearly twice as likely to delay having children because of the demands of training (72.6 percent versus 39.2 percent) and to experience infertility (26.3 percent versus 12.5 percent). Among the childless plastic surgeons, women were 11 times more likely to say they did not want children compared with men (20.1 percent versus 1.8 percent). CONCLUSIONS: Poor institutional maternity support results in a persistent, wide gap in reproductive outcomes between female and male plastic surgeons. Establishing a universal, comprehensive parental support policy is essential to closing that gap.

Can Plastic Surgeons Maintain Professionalism within Social Media?

Plastic surgeons have evolved their methods of reaching potential patients by using various forms of social media. Such platforms can educate, inform, and, for some, entertain. Social media now allows consumers to compare themselves to a much wider, if not global, set of peers that might further exacerbate their anxiety regarding their appearance. Plastic surgeons should ensure that use of patient images does not violate privacy or create unreasonable expectations about the results that can be obtained; nor should plastic surgeons' marketing objectify women. Professionalism on the part of plastic surgeons, along with the utmost respect for patients, must remain paramount.

Postoperative Nausea and Vomiting with Plastic Surgery: A Practical Advisory to Etiology, Impact, and Treatment.

Ambulatory surgery is common in plastic surgery, where many aesthetic and reconstructive procedures can be performed in hospitals, ambulatory surgery centers, or office-based surgery facilities. Outpatient surgery offers advantages to both the patient and the surgeon by increasing accessibility, flexibility, and convenience; lowering cost; and maintaining high-quality care. To optimize a patient's experience and comfort, postoperative nausea and vomiting (PONV) should be prevented. However, in those patients who develop PONV, it must be appropriately managed and treated. The incidence of PONV is variable. It is often difficult to accurately predict those patients who will develop PONV or how they will manifest symptoms. There are a variety of recommended "cocktails" for PONV prophylaxis and treatments that are potentially effective. The decision regarding the type of treatment given is often more related to provider preference and determination of side-effect profile, rather than targeted to specific patient characteristics, because of the absence of large volumes of reliable data to support specific practices over others. Fortunately, there are several tenets for the successful prevention and treatment of PONV we have extracted from the literature and summarize here. The following is a summary for the practicing plastic surgeon of the current state of the literature regarding PONV cause, risk factors, prophylaxis, and treatment that may serve as a guide for further study and practice management.

Gender Differences in the Professional and Personal Lives of Plastic Surgeons.

BACKGROUND: Although the number of women becoming plastic surgeons has increased during the past six decades, in comparison with the current gender parity in medical schools, plastic surgery still attracts disproportionately more men. Previous studies have shown disparities in the professional and personal lives of female and male plastic surgeons. A survey study was conducted to identify current challenges women and men encounter in the pursuit of a plastic surgical career to guide remedial strategies. METHODS: An anonymous electronic survey was distributed to American Society of Plastic Surgeons members and candidates for comparison between sexes. Differences were tested by the Fisher's exact and chi-square tests. RESULTS: Women were more likely than men to have experienced sexism or bias. Women were less likely to be married; be satisfied with work-life balance; or feel recognized for ideas, authorship, promotions, or raises. Women felt that their sex was a disadvantage in career advancement, with one exception: unlike men, women felt many patients chose them because of their sex. Despite these challenges, over 80 percent of all plastic surgeons were satisfied with their choice of career. CONCLUSIONS: Traditions and gender bias create disparities in the personal and professional lives of female and male plastic surgeons. Our specialty must make concrete changes to promote all plastic surgeons, both women and men, to thrive personally and professionally.

Correlation between extraversion and regional cerebral blood flow in response to olfactory stimuli.

OBJECTIVE: Extraversion, a trait associated with individual differences in approach motivation and the experience of positive emotional states, is negatively correlated with certain psychiatric disorders, including depression and social phobia. The authors examined the correlation between extraversion and regional cerebral blood flow (rCBF) while participants were exposed to olfactory stimuli in order to further characterize individual differences in hedonic processing associated with this trait. METHOD: Twelve healthy participants were exposed to pleasant and unpleasant odors while rCBF was measured using [(15)O] water PET. The NEO Five-Factor Inventory was used to assess extraversion. Associations between extraversion scores and rCBF in each olfactory stimulus condition were assessed by correlational analysis. RESULTS: During the pleasant smell condition, extraversion was correlated with rCBF in the amygdala and occipital cortex. During the unpleasant smell condition, extraversion was correlated with rCBF in the occipital cortex and inferior temporal gyrus. CONCLUSIONS: These results provide important evidence for the biological basis of extraversion and indicate that there are systematic individual differences in patterns of brain activation in response to affective stimuli.

Factors influencing the acceptance of changes in antiretroviral therapy among HIV-1-infected patients.

Physicians routinely consider modifying antiretroviral therapy (ART) regimen for their patients with HIV. Little is known about the factors associated with patients' willingness to accept providers' recommended ART changes. This multicenter prospective observational study examined factors associated with willingness to accept ART changes recommended by their providers among HIV-infected adults from six urban outpatient HIV clinics. Patients were surveyed using the Patient Attitudes about Altering Antiretroviral Therapy Survey questionnaire (PAAARTS). Factors associated with willingness to accept ART changes were assessed using a multivariate generalized estimating equation (GEE) model to account for correlated responses. The Classification and Regression Trees (CART) analysis was also performed to determine subgroups of patients with higher acceptance of change. 216 of 289 patients (75%) definitely accepted recommended changes. Odds for acceptance were 3.2, 2.3, and 2.8 times higher for patients with higher attitudes and beliefs about ART (p < 0.01; 95% confidence interval [CI] = 1.59, 6.52), patients who rated their provider's care as excellent (p < 0.05; 95% CI = 1.07, 4.78), and non-Hispanic patients (p < 0.05; 95% CI 1.03, 7.57), respectively. CART analysis showed similar results and identified that when patients had less positive attitude about ART, acceptance rates were higher for non-Hispanic patients with higher assessments of their patient-provider communication. While most patients accepted providers' recommendation for ART changes, this willingness was influenced by both patients' attitudes and beliefs about ART and their assessment of either the effectiveness of patient-provider communication or their rating of providers' care. ART acceptance rates among Hispanic patients were lower.

Differential effects of pretraining influences on readiness to change.

Training and development are integral to organizational change but are difficult to accomplish effectively in dynamic and complex work environments. Such environments can lead to nonoptimal training conditions that reduce individuals' readiness to change and training effectiveness. On the basis of the transtheoretical model of change (J. O. Prochaska, C. C. DiClemente, & J. C. Norcross, 1992), the authors examined pretraining influences (choice, social support, and motivation to learn) on readiness to change under nonoptimal training conditions. They examined specific dimensions of readiness to change rather than a global readiness to change construct. Participants were 183 driving under the influence (DUI) offenders participating in a court-mandated, alcohol-related Weekend Intervention Program. Perceived choice to attend training, social support, and motivation to learn affected readiness to change when individuals were resisting, considering, acting on, or maintaining behavior or attitude change. These effects were also dependent on age. Results suggest how training effectiveness could be improved when trainees are least likely to learn.

The effect of HIV/AIDS disease progression on spirituality and self-transcendence in a multicultural population.

This study examined the relationship of sociodemographic and clinical factors with spirituality and self-transcendence in people with HIV/AIDS. It involved 420 HIV/AIDS patients from an HIV clinic who were predominantly Hispanic (79%) and male (82%), with a mean age of 39 years. Subjects completed spirituality, self-transcendence, health status, and depression scales. Medical charts were reviewed to obtain demographics, current therapies, depression diagnosis, CD4 cells (sometimes called T-cells), and viral load levels. Self-transcendence was related to levels of energy (p < .05) and acculturation (p < .05). Spirituality was related to levels of energy (p < .001) and pain (p < .02). Neither disease progression nor severity was related to self-transcendence or spirituality. The findings suggest the concept of self-transcendence may not be culturally meaningful to Hispanic patients. The development of valid and reliable tools specific for this population is important for future research.
