ABSTRACT

OBJECTIVE: Review the subsequent impact of recommendations made by the 2004 American Surgical Association Blue Ribbon Committee (BRC I) Report on Surgical Education. BACKGROUND: Current leaders of the American College of Surgeons and the American Surgical Association convened an expert panel to review the impact of the BRC I report and make recommendations for future improvements in surgical education. METHODS: BRC I members reviewed the 2004 recommendations in light of the current status of surgical education. RESULTS: Some of the recommendations of BRC I have gained traction and have been implemented. There is a well-organized national curriculum and numerous educational offerings. There has been greater emphasis on preparing faculty to teach and there are ample opportunities for professional advancement as an educator. The number of residents has grown, although not at a pace to meet the country's needs either by total number or geographic distribution. The number of women in the profession has increased. There is greater awareness and attention to resident (and faculty) well-being. The anticipated radical change in the educational scheme has not been adopted. Training in surgical research still depends on the resources and interests of individual programs. Financing student and graduate medical education remains a challenge. CONCLUSIONS: The medical landscape has changed considerably since BRC I published its findings in 2005. A contemporary assessment of surgical education and training is needed to meet the future needs of the profession and our patients.

ABSTRACT

OBJECTIVE: An expert panel made recommendations to optimize surgical education and training based on the effects of contemporary challenges. BACKGROUND: The inaugural Blue Ribbon Committee (BRC I) proposed sweeping recommendations for surgical education and training in 2004. In light of those findings, a second BRC (BRC II) was convened to make recommendations to optimize surgical training considering the current landscape in medical education. METHODS: BRC II was a panel of 67 experts selected on the basis of experience and leadership in surgical education and training. It was organized into subcommittees which met virtually over the course of a year. They developed recommendations, along with the Steering Committee, based on areas of focus and then presented them to the entire BRC II. The Delphi Method was chosen to obtain consensus, defined as>80% agreement amongst the panel. Cronbach alpha was computed to assess the internal consistency of three Delphi rounds. RESULTS: Of 50 recommendations, 31 obtained consensus in the following aspects of surgical training (# consensus recommendation /# proposed): Workforce (1/5), Medical Student Education (3/8), Work Life Integration (4/6), Resident Education (5/7), Goals, Structure and Financing of Training (5/8), Education Support and Faculty Development (5/6), Research Training (7/9), and Educational Technology and Assessment (1/1). The internal consistency was good in Rounds 1 and 2 and acceptable in Round 3. CONCLUSIONS: BRC II used the Delphi approach to identify and recommend 31 priorities for surgical education in 2024. We advise establishing a multidisciplinary surgical educational group to oversee, monitor and facilitate implementation of these recommendations.

ABSTRACT

BACKGROUND: The U.S. Food and Drug Administration has approved four distinct formulations of botulinum toxin (BoNT) serotypes A and B (BoNTA and BoNTB) for medical use. These four products are indicated for many medical applications, but the three BoNTA formulations are the most widely used worldwide and are the only products approved for aesthetic use. The latest approval of a BoNTA with no complexing proteins (incobotulinumtoxinA) necessitates a review and discussion of differences between available formulations and the effect that these differences may have on clinical practice. OBJECTIVES: To review the history, science, safety information, and current and emerging applications of BoNT in clinical and cosmetic practice and to compare commercially available BoNTA formulations. METHODS AND MATERIALS: Publications, clinical trials, and author experience were used as a basis for an up-to-date review of BoNT and its use in human medicine. The similarities and differences between formulations are presented, and diffusion, spread, equivalency ratios, stability, and storage are discussed. RESULTS: Each commercial formulation has unique characteristics that may influence its use in aesthetic medicine. Familiarity with the similarities and differences between products will aid physicians in making patient care decisions. CONCLUSION: New formulations, emerging uses, and continued research into the science and uses of BoNTA will lead to increasingly refined therapeutic approaches and applications. Continued education is important for physicians to optimize use of the agent according to the most current evidence and approaches.

ABSTRACT

BACKGROUND: Superficial dermal injection of hyaluronic acids (HAs) has not been well studied. OBJECTIVES: To study HAs injected into the superficial dermis using ultrasound examination and measurements, to evaluate induration and pain, and to examine histology. MATERIALS AND METHODS: Three commercial HAs were injected into the superficial dermis (0.2 mL). The HAs used were a biphasic gel, a monophasic monodensified gel, and a monophasic polydensified gel. Ultrasound measurements and images were obtained, pain assessed, and biopsies performed at 7 days. RESULTS: Participants experienced pain from the HAs that did not contain lidocaine. After 8 days, the biphasic HA papules appeared erythematous, with two-thirds reporting the biphasic HA papules as tender. Ultrasound demonstrated superficial placement of HA gels in the upper dermis. The gels each exhibited unique characteristic patterns on ultrasound. Skin biopsies of the superficial dermal placement confirmed earlier patterns. Superficial placement of the biphasic product is associated with tenderness and an eosinophilic inflammatory infiltrate. CONCLUSION: Superficial placement of HAs is possible, as demonstrated by ultrasonography. Gels that do not have lidocaine within them are more painful. Injection of biphasic HA gels superficially in the dermis is associated with clinical erythema and tenderness and histology showing an eosinophilic infiltrate.

ABSTRACT

BACKGROUND: Twenty grading scales have been developed to assess age-related facial changes. Until now, the validity with regard to the patient's actual age and the clinical importance of combined measurement tools to describe facial aging was unclear. OBJECTIVE: To investigate the reliability and validity of a total face score and three global face assessment scales for estimated age, estimated aesthetic treatment effort, and signs of aging in the facial units. MATERIALS AND METHODS: Descriptive, reliability, correlation, and principal component analyses based on the assessment of 50 subjects by 12 raters using the 20 grading scales and the global face assessment scales. RESULTS: Inter- and intrarater reliability was high for the total face score and for the scales on estimated age and aesthetic treatment effort. Actual age was highly correlated with these three measures. Facial aging was indicated particularly by scales of the lower face. CONCLUSION: The aesthetic grading scales and global scales on estimated age and aesthetic treatment effort are reliable and valid instruments. The results suggest that a more-comprehensive evaluation of the human face and its age-related changes can help to identify important areas of facial aging and to define optimal aesthetic treatment strategies.

ABSTRACT

BACKGROUND: Age-related upper face changes such as wrinkles, lines, volume loss, and anatomic alterations may affect quality of life and psychological well-being. The development of globally accepted tools to assess these changes objectively is an essential contribution to aesthetic research and routine clinical medicine. OBJECTIVE: To establish the reliability of several upper face scales for clinical research and practice: forehead lines, glabellar lines, crow's feet (at rest and dynamic expression), sex-specific brow positioning, and summary scores of forehead and crow's feet areas and of the entire upper face unit. METHODS AND MATERIALS: Four 5-point photonumerical rating scales were developed to assess glabellar lines and sex-specific brow positioning. Twelve experts rated identical upper face photographs of 50 subjects in two separate rating cycles using all eight scales. Responses of raters were analyzed to assess intra- and interrater reliability. RESULTS: Interrater reliability was substantial for all upper face scales, aesthetic areas, and the upper face score except for the brow positioning scales. Intrarater reliability was high for all scales and resulting scores. CONCLUSION: Except for brow positioning, the upper face rating scales are reliable tools for valid and reproducible assessment of the aging process.

ABSTRACT

BACKGROUND: The improvement of aesthetic treatment options for age-related mid face changes, such as volume loss, and the increase in patient expectations necessitates the development of more-complex and globally accepted assessment tools. OBJECTIVE: To develop three grading scales for objective assessment of the infraorbital hollow and upper and lower cheek fullness and to establish the reliability of these scales for clinical research and practice. METHODS AND MATERIALS: Three 5-point rating scales were developed to assess infraorbital hollow and upper and lower cheek fullness objectively. Twelve experts rated identical mid face photographs of 50 subjects in two separate rating cycles using the mid face scales. Test responses of raters were analyzed to assess intra- and interrater reliability. RESULTS: Interrater reliability was substantial for the infraorbital hollow, upper cheek fullness, and lower cheek fullness scales. Intrarater reliability was high for all three scales. Both of the cheek fullness scales yielded higher reliabilities when three rather than two views were used to assess the volume changes of the cheek. CONCLUSION: The mid face scales are reliable tools for valid and reproducible assessment of age-related mid face changes.

ABSTRACT

BACKGROUND: Aging in the lower face leads to lines, wrinkles, depression of the corners of the mouth, and changes in lip volume and lip shape, with increased sagging of the skin of the jawline. Refined, easy-to-use, validated, objective standards assessing the severity of these changes are required in clinical research and practice. OBJECTIVE: To establish the reliability of eight lower face scales assessing nasolabial folds, marionette lines, upper and lower lip fullness, lip wrinkles (at rest and dynamic), the oral commissure and jawline, aesthetic areas, and the lower face unit. METHODS AND MATERIALS: Four 5-point rating scales were developed to objectively assess upper and lower lip wrinkles, oral commissures, and the jawline. Twelve experts rated identical lower face photographs of 50 subjects in two separate rating cycles using eight 5-point scales. Inter- and intrarater reliability of responses was assessed. RESULTS: Interrater reliability was substantial or almost perfect for all lower face scales, aesthetic areas, and the lower face unit. Intrarater reliability was high for all scales, areas and the lower face unit. CONCLUSION: Our rating scales are reliable tools for valid and reproducible assessment of the aging process in lower face areas.

ABSTRACT

BACKGROUND: Sagging of the neck aesthetic area is an important indicator of age. The development of complex and globally accepted tools for proper assessment of the change in neck volume is an essential contribution to aesthetic research and the routine clinical setting. OBJECTIVE: To develop a grading scale for the objective assessment of the neck volume and to establish the reliability of this scale for clinical research and practice. MATERIALS AND METHODS: A 5-point rating scale was developed to assess neck volume objectively. Twelve experts rated frontal and lateral neck photographs of 50 subjects in two separate rating cycles using the neck volume scale. Responses of raters were analyzed to assess inter- and intrarater reliability. RESULTS: Interrater reliability for the neck volume scale was almost perfect, with intraclass correlation coefficients for the first and second rating cycles of 0.85 and 0.84, respectively. Intrarater reliability for the neck volume scale was high (0.90) and Pearson correlation coefficients ranged between 0.88 and 0.95 and were statistically significant. CONCLUSION: The neck volume scale demonstrates optimal reliability for clinical research and practice.

ABSTRACT

A topical gel containing a proprietary mixture of over 110 growth factors, cytokines, and soluble matrix proteins secreted by human dermal fibroblasts was evaluated for safety and efficacy in the treatment of mild to severe facial photodamage. In a double-blind study, 60 subjects were randomly assigned to receive either active gel or the vehicle and applied twice daily for 6 months along with a moisturizing cleanser and sunscreen. Efficacy (profilometry, photography, and clinical assessment) and safety (adverse event reporting) measures were evaluated at 0, 3, and 6 months. Treatment with the active gel for 3 months produced greater reduction in fine lines and wrinkles than the vehicle treatment as measured by objective and subjective assessment techniques. The results were either statistically significant (P < or = .05) or trending towards statistical significance (P < or = .1). This study demonstrates that addition of a topical formulation of growth factors and cytokines to a basic skin care regimen reduces the signs of photoaging.

ABSTRACT

New requirements for vascular surgery training allow several routes to Board eligibility in the specialty. Individuals can enter vascular residency directly from medical school, after 3 years of surgical residency, or after completion of the traditional 5 years of surgery training. Vascular surgery program directors will be faced with the challenges of obtaining institutional support, designing an acceptable educational program, and working closely with the general surgery program director to ensure both programs are successful. Faculty in the vascular program may find working with residents right out of medical school or after only 3 years of surgery training to be a challenge, especially in terms of developing the requisite technical skills. Residents must be able to demonstrate mastery of the six competencies in addition to the skills of vascular surgery. Because, in some ways, this new vascular training scheme is an experiment in redesigning all surgical education, the vascular community will need to carefully evaluate the results by monitoring the practices of those who graduate from these programs.

ABSTRACT

The purpose of this study was to assess resident knowledge related to breast disease at the University of Florida. In addition, we surveyed graduates of our surgery program regarding the importance of breast disease in their surgical practice and we determined if the completion of postgraduate courses on breast disease influenced patient outcome measures. In the decade of the 1990s, we compared the American Board of Surgery In-Service Training Examination (ABSITE) scores of residents rotating on the breast service in the 6 months immediately prior to examination (June-January) with those residents who had not rotated on the breast service within the 6 months leading up to the ABSITE examination. We also compared ABSITE scores of surgery residents at the University of Florida at Gainesville (breast service) to surgery residents at the University of Florida at Jacksonville (no breast service). Finally, we surveyed graduates of the general surgery program at the University of Florida at Gainesville (1980-1998) to determine the importance of breast disease in their practices and if the completion of postgraduate courses on breast disease influenced rates of breast conservation and immediate breast reconstruction. Residents who rotated on the breast service in the 6 months prior to the ABSITE had significantly fewer incorrect breast-related ABSITE questions than residents who had not rotated on the breast service. Those graduates who had taken postgraduate courses in breast disease responded that they were more likely to perform breast-conserving surgery. There was also a trend for graduates who had completed postgraduate courses on breast disease to respond that they were more likely to perform immediate breast reconstruction following mastectomy. Limiting breast surgery to a single service does not appear to improve resident accumulation and retention of breast disease-related knowledge. Graduates who complete postgraduate courses related to breast disease are more likely to perform breast-conserving surgery and immediate reconstruction following mastectomy. Since the management of breast disease comprises a significant part of general surgical practice, surgical educators must ensure adequate resident education and evaluation with respect to breast disease.

ABSTRACT

OBJECTIVES: Little published literature describes accurate evaluation and assessment of surgical residents' technical competencies. Work-hour limitations and the proposed changes in training duration challenge our ability to provide core technical competencies, particularly during PGY-1-2. We identified minimally invasive surgery as a particularly challenging competency training area, requiring significant allocation of resident and faculty time and resources, with inconsistent training results. This project evaluated a standardized competency training curriculum in minimally invasive surgery in comparison to existing training. METHODS: The Laparoscopy 101-a Resource for Resident Education minimally invasive surgery competency training curriculum consists of CD-ROM-based self-paced didactic self-instruction modules, skills laboratories, and web-based testing, evaluation, and reporting. Five didactic self-study modules and their corresponding web-based examinations were selected for this study. PGY 1-2 residents (11/group) were enrolled. PGY-1 residents received no formal minimally invasive surgery training in our program before participating, whereas PGY-2 residents were exposed to the minimally invasive surgery training program in place in our department. PGY-1 residents completed the training modules and web-based testing over 4 days. PGY-2 residents underwent testing before (pre-test) and after (post-test) completing identical training modules and testing over an identical time period. Test results were examined and compared in both groups. A user-satisfaction survey assessed resident opinions about the quality of the curriculum, use of the CD-ROM/web-based system, and trainee perceptions about performance. RESULTS: PGY-2 Pre-test scores were equivalent to PGY-1 scores after training (mean overall performance, 52.4% vs 65.5% p = ns). PGY-2 Post-test scores were significantly higher when compared with pre-test scores (mean overall performance; pre: 52.4% vs post: 85.3% p <== 0.001). Interestingly, post-training scores were significantly higher for PGY-2 than PGY-1 (mean overall performance PGY-1: 52.4% vs PGY-2: 65.5% p = ns). Competencies achieved persisted 6 months after initial training in both PGY 1-2 groups without additional training using this curriculum. Overall user satisfaction was positive in each category evaluated. CONCLUSIONS: The Laparoscopy 101 minimally invasive surgery curriculum (1) p;rovides a structured self-paced curriculum for minimally invasive didactic training that is well accepted by trainees; (2) yields PGY-1 competencies equivalent to PGY-2 who receive training in our department's existing program; and (3) yields significant improvement in PGY-2 minimally invasive surgery competencies. Training effects persist to 6 months without reinforcement. Our observations of PGY-2 performance and competency suggest that this training would best be instituted during PGY-2.

ABSTRACT

BACKGROUND: Concerns regarding preparation of residents for independent surgical practice are widespread and support for junior surgeons entering practice is variable across institutions and practices. The American College of Surgeons (ACS) Division of Education partnered with the Accreditation Council for Graduate Medical Education (ACGME) to convene a National Invitational Conference to define key issues relating to the transition to practice and develop recommendations to address various challenges. OUTCOMES OF THE NATIONAL INVITATIONAL CONFERENCE: Leaders from ACS, ACGME, certifying boards, residency review committees, program director organizations, and professional societies representing the breadth of surgical specialties, along with other key stakeholders, were invited to participate in the 1.5-day conference in July 2012. Key recommendations generated during the conference included the need to focus on the transition to practice within the context of the continuum of professional development; definition of specific levels of knowledge and skills expected of graduating surgery residents; development and adoption of competency-based methods for training, assessment, and advancement of residents; implementation of special interventions during the chief resident year to prepare residents for practice; robust evaluations of residents before graduation; intake assessments of junior surgeons during the onboarding processes; and effective mentorship for junior surgeons as they enter practice. Recommendations also highlighted major regulatory, legal, and financial issues. The key role of ACS and other national organizations in implementing the recommendations was underscored. CONCLUSION: The recommendations from the conference should be of great help in addressing various challenges associated with the transition from surgery residency to independent practice.

ABSTRACT

Belotero Balance is a novel highly cross-linked hyaluronic acid that uses cohesive polydensified matrix technology to achieve cohesive gel; improved adaptation by the dermis; and a soft, smooth fill. Several studies have now compared Belotero Balance to bovine collagen and other hyaluronic acids. Two pivotal studies demonstrated the noninferiority and superiority of Belotero Balance to bovine collagen. In the first study, more than half of the patients maintained optimal correction at 6 months on the Belotero-treated side of the face. The second of those two studies followed patients to week 96 and demonstrated that the effects of Belotero Balance in this long-term, open-label study persisted in the majority of subjects without repeated treatment for at least one interval of 48 weeks. The filler was well tolerated, with only one of 34 total adverse events (injection-site bruising) considered to be related to the study device. A third study compared the safety and efficacy of other hyaluronic acids (i.e., Juvéderm and Restylane) with Belotero Balance. In this study, the safety profiles of all three hyaluronic acids were generally favorable, with site-specific adverse events mild to moderate and comparable across each hyaluronic acid. Aesthetic results were also similar, although Belotero Balance resulted in greater evenness than Restylane at 4 weeks by one indicator used in the study. Finally, a 5-year retrospective safety review of 317 patients treated with Belotero Balance over a 5-year period revealed no severe adverse events in any patients, including the absence of persistent nodules or granulomas.

ABSTRACT

With the proliferation of dermal fillers in the aesthetic workplace have come instructions from various manufacturers regarding dermal placement. Determination of injection needle location in the dermis has in large part been based on physician expertise, product and needle familiarity, and patient-specific skin characteristics. An understanding of the precise depth of dermal structures may help practitioners improve injection specificity. Unlike other dermal fillers that suggest intradermal and deep dermal injection planes, a new hyaluronic acid with a cohesive polydensified matrix may be more appropriate for the superficial dermis because of its structure and its high degree of integration into the dermis. To that end, the authors designed a small study to quantify the depth of the superficial dermis by means of ultrasound and histology. Using ultrasound resources, the authors determined the depths of the epidermis, the dermis, and the reticular dermis in the buttocks of six patients; the authors then extrapolated the depth of the superficial reticular dermis. Histologic studies of two of the patients showed full integration of the product in the reticular dermis. Following determination of injection depths and filler integration, the authors describe a technique ("blanching") for injection of the cohesive polydensified matrix hyaluronic acid into the superficial dermis. At this time, blanching is appropriate only for injection of the cohesive polydensified matrix hyaluronic acid known as Belotero Balance in the United States, although it may have applications for other hyaluronic acid products outside of the United States.
