Surgical Management of Breast Amyloidosis.

Amyloidosis is characterized by extracellular deposition of insoluble misfolded beta-pleated proteins. Amyloid disease involving the breast is rare and there is a paucity of literature guiding surgical management in caring for these patients. In this article we review medical and surgical management with an emphasis on post mastectomy breast reconstruction. We propose an algorithm for breast reconstructive options based on unique considerations in this patient population. An institutional database at the Medical College of Wisconsin was used to identify patients diagnosed with breast amyloidosis from 2011 to 2021. We utilized the electronic medical record to present patient demographics, diagnostic and treatment data regarding the medical and surgical management of these patients. Five women were identified with a median age of 70 years and a median follow up of 19 months (range, 9-80 months). All patients were diagnosed with light chain (AL) type of amyloidosis. Systemic amyloidosis was identified in 3 patients and localized disease was identified in 2 patients. Concurrent breast malignancy was identified in 2 patients who underwent skin-sparing mastectomies followed by breast reconstruction with both prosthetic and autologous techniques. Both prosthetic and autologous reconstructive techniques are safe in patients with amyloidosis, however careful consideration and preoperative work-up are warranted to avoid complications in this vulnerable population. Further studies are warranted to improve surgical outcomes in patients with amyloidosis involving the breast.

Changes in Subspecialty Interest of Plastic Surgery Residents With Progression of Training: Impact on Academic Attrition.

BACKGROUND: Plastic surgery residency applicants often express interest in academic subspecialties, but only a small percentage of graduating residents pursue academic careers. Identifying reasons for academic attrition may help training programs address this discrepancy. METHODS: A survey was sent to plastic surgery residents through the American Society of Plastic Surgeons Resident Council to assess interest in 6 plastic surgery subspecialties during junior and senior years of training. If a resident changed their subspecialty interest, the reasons for change were recorded. The importance of different career incentives over time were analyzed with paired t tests. RESULTS: Two hundred seventy-six plastic surgery residents of 593 potential respondents (46.5% response rate) completed the survey. Of 150 senior residents, 60 residents reported changing interests from their junior to senior years. Craniofacial and microsurgery were identified as the specialties with the highest attrition of interest, while interest in esthetic, gender-affirmation, and hand surgery increased. For residents who left craniofacial and microsurgery, the desire for higher compensation, to work in private practice, and the desire for improved job opportunities significantly increased. The desire for improved work/life balance was a prominent reason for subspecialty change among senior residents who changed to esthetic surgery. CONCLUSIONS: Plastic surgery subspecialties associated with academia, such as craniofacial surgery, suffer from resident attrition due to a variety of factors. Increased retention of trainees in craniofacial surgery, microsurgery, and academia could be improved through dedicated mentorship, improved job opportunities, and advocacy for fair reimbursement.

Do Dedicated Research Years during Medical School Predict Academic Productivity during Residency?

BACKGROUND: Evidence regarding whether medical school research portends resident research is limited. This information will provide program directors with data that may be useful for selecting applicants with a commitment to continued academic productivity. METHODS: A questionnaire distributed via the American Society of Plastic Surgeons Resident Council to residents in 44 plastic surgery training programs in May 2020 assessed participation in dedicated research years during medical school, the number of publications completed before residency, and the total number of publications by each resident at the time of the survey. One-way ANOVA and post hoc analysis determined significant associations between publication count and number of research years. RESULTS: Of the 256 included respondents, 203 did not complete a research year during medical school, 44 completed 1 research year, and nine completed 2 research years. Mean publications before residency were higher for participants who took 1 or 2 research years (9.88 and 27.60, respectively) compared with those who did not (4.83, P < 0.001). A comparison of total publications during residency similarly revealed increased productivity by individuals who took 1 or more research years; however, there was no difference between the number of publications completed during residency for individuals who took 1 versus 2 years (P = 0.23). CONCLUSIONS: Residents with research experience during medical school continue to produce an increased number of publications during residency compared with those without, suggesting dedicated research years taken during medical school serve as a predictor of academic productivity in plastic surgery residents.

Novel Approach of Mandibular Distraction to Avoid Tracheostomy in KAT6B-related Gene Disorders.

Previously, severe upper airway obstruction in patients with retrognathia and glossoptosis has been managed with tracheostomy. However, tracheostomy is associated with significant morbidity. In recent years, mandibular distraction has become an alternative management strategy in infants, but these applications have been limited to patient populations with retrognathia and glossoptosis. The authors present 2 unique cases of patients with KAT6B-related gene disorders, who present with a paradox of tongue-based airway obstruction in the absence of retrognathia. In both cases mandibular distraction osteogenesis with an obliquely oriented vector was successfully performed and both children avoided the need for tracheostomy.

Spring-Assisted Distraction Osteogenesis for the Treatment of Shunt-Induced Craniosynostosis.

Shunt-induced craniosynostosis is a rare complication of ventricular shunting for hydrocephalus in pediatric patients. Although the exact pathophysiology of this form of secondary craniosynostosis is not well understood, the current understanding is that persistent drainage of the ventricular shunt causes decreased dural tension, resulting in decreased expansile force on the cranium and premature sutural fusion. Due to the low incidence of this complication, there is no consensus on the ideal treatment for shunt-induced craniosynostosis. In recent years, distraction osteogenesis has been employed with greater frequency, as it is felt to counter the fundamental problem of decreased expansile force on the cranium. However, in a patient with a ventricular shunt, placement of external hardware in close proximity to the shunt could cause significant morbidity due to the increased risk of shunt infection. We present the management of a patient with shunt-induced craniosynostosis who continued to be shunt-dependent. We chose to use fully buried springs to create an expansile force on the cranium as an alternative to external distractors so as to mitigate the risk of infection. We demonstrate that spring-assisted distraction osteogenesis can be an effective treatment modality for patients with shunt-induced craniosynostosis. This method should be considered in patients with contraindications to external distraction devices, such as ongoing shunt dependency.

Superficial Dermal Fillers with Hyaluronic Acid.

Minimally invasive aesthetic procedures with hyaluronic acid filler have increased drastically since their development in 1989. Patients' desires to avoid surgery and achieve rapid results with minimal recovery led to a transformation in facial plastic surgery, demanding that aesthetic surgeons become proficient in nonsurgical augmentation. Over the years, new hyaluronic acid filler products were developed with different intrinsic properties, allowing clinicians to better treat different deficiencies of the face, reduce postprocedural pain, and optimize outcomes. The purpose of this article is to review the current state of nonsurgical facial plastic surgery with the superficial dermal filler, hyaluronic acid.

Corner of the Mouth-Reversing the Earliest Sign of Aging.

As individuals age, distinct anatomical changes of the bone and soft tissue result in the development of rhytids in the perioral region. Most notably, the oral commissures turn downward, creating the appearance of a perpetual frown and adding years to the facial appearance. The purpose of this article is to review the anatomical changes associated with perioral aging as well as discuss potential treatment options for perioral rejuvenation particularly at the level of the oral commissures. Lastly, this article covers the senior author's technique for improving oral commissures and restoring youthful appearance of the perioral region.

Topical skin therapies in subjects undergoing full facial rejuvenation.

BACKGROUND: Cosmeceutical therapies including face washes, moisturizers, chemical peels and antioxidant formulations are intended to improve the esthetic appearance of skin. The use of these products as adjuncts to full facial rejuvenation with hyaluronic acid filler and abobotulinumtoxinA may improve cosmetic and socio-esthetic outcomes. OBJECTIVE: To characterize the effect of skin care products in subjects undergoing full facial rejuvenation with abobotulinumtoxinA and hyaluronic acid in improving facial skin appearance, patient satisfaction, and projected first impressions. METHODS: Twenty subjects were recruited and divided into two treatment groups. Subjects in Group A followed a standard skin care regimen, whereas subjects in Group B received a more robust skin care regimen including chemical peels and antioxidant formulations. All subjects underwent facial rejuvenation treatments with hyaluronic acid at Visit 2 and with abobotulinumtoxinA at Visit 7. Patient esthetic improvement, satisfaction, self-esteem, and first impression were evaluated via the Fitzpatrick Wrinkle Assessment Scale, Global Aesthetic Improvement Scale, Skin Quality Assessment, Heatherton & Polivy State Self-Esteem Scale, Subject Satisfaction Scale, and the First Impressions Questionnaire. RESULTS: Both treatment groups experienced significant improvements in the Skin Quality Assessment, Fitzpatrick Wrinkle Assessment Scale, Heatherton and Polivy State Self-Esteem Scale, and First Impressions Questionnaire. CONCLUSION: The cosmeceutical therapies used in this study in combination with abobotulinumtoxinA and hyaluronic acid filler improved subjects' skin quality, self-esteem, and projected first impressions. Larger studies are needed to determine the most efficacious combination of topical skin therapies with facial rejuvenation therapy.

Major Complications and 30-Day Morbidity for Single Jaw Versus Bimaxillary Orthognathic Surgery as Reported by NSQIP.

OBJECTIVE: Acute complications in orthognathic surgery are reported in single-institution studies with small sample sizes. We aimed to analyze risk factors for acute complications using a national data set to better inform surgical decision-making. METHODS: 2005-2015 National Surgical Quality Improvement Program (NSQIP) data sets were analyzed for patients undergoing Le Fort 1 and/or bilateral sagittal split osteotomies (BSSO) for nontraumatic indications. Demographics, comorbidities, medical, and surgical 30-day complications were tabulated. A logistic regression model was used to determine predictors of complications. RESULTS: Five hundred eight patients met the inclusion criteria: 228 underwent Le Fort I osteotomies, 152 BSSO, and 128 patients underwent both during a single surgical encounter. Overall complication rate was 4.5% (23/508). Superficial infection was the most common complication (11 in BSSO and 2 in Le Fort I cohorts). Increasing age and undergoing BSSO alone were associated with higher overall complication rates (P < .05) and surgical complications specifically (P < .05). Patients undergoing the combined procedure had shorter operative time (208 minutes) than the times for Le Fort I osteotomies alone (177 minutes) and BSSO alone (155 minutes) added together and did not have a longer hospital stay (P = .608) or increased need for transfusion (P = 1.0) compared to the surgeries being done separately. CONCLUSION: This is the first complication risk factor analysis for Le Fort I osteotomy and BSSO using the multi-institutional NSQIP data set. Combining BSSO and Le Fort I osteotomy leads to a shorter overall operative time and does not increase hospital stay duration or 30-day complication rate when compared to the 2 procedures being done separately.

Assessment of the Impact of Perioral Rejuvenation With Hyaluronic Acid Filler on Projected First Impressions and Mood Perceptions.

BACKGROUND: Small-particle hyaluronic acid filler is approved for lip augmentation and correction of perioral rhytides. Treatment with this product may improve facial aesthetics, projected first impression, and self-perception of mood. OBJECTIVE: To determine the effect of perioral rejuvenation with hyaluronic acid on patient perception of mood and projected first impression. MATERIALS AND METHODS: Seventeen subjects underwent perioral rejuvenation treatment with small-particle hyaluronic acid filler. Each subject underwent photography and completed 2 surveys measuring self-perception of mood before treatment and after achieving an optimal cosmetic result. Aesthetic improvement with treatment was assessed using the Global Aesthetic Improvement Scale and the Oral Commissure Severity and Perioral Line Severity scales. Seventeen hundred blinded evaluators rated pre-treatment and post-treatment photographs of the subjects using a First Impressions Questionnaire. RESULTS: Perioral filler treatment significantly improved pre-treatment and post-treatment scores for happiness within the Happiness Measures Scale. This treatment was found to significantly improve projected first impression across all categories. CONCLUSION: Small-particle hyaluronic acid filler treatment for perioral rejuvenation is an effective method for improving physical appearance as well as first impressions. Larger studies are necessary to verify whether perioral rejuvenation with hyaluronic acid offers enhanced self-perception of mood.

A Randomized Study to Assess the Efficacy of Skin Rejuvenation Therapy in Combination With Neurotoxin and Full Facial Filler Treatments.

BACKGROUND: Although non-surgical treatment options for facial rejuvenation are well-established, the literature remains limited regarding the combined effect of topical skin treatment with filler and neurotoxin on patient appearance and satisfaction. The objectives of this study were to assess the impact of a skin rejuvenation therapy in combination with neurotoxin or hyaluronic acid filler injection on skin quality and general aesthetic improvement as well as on short-term self-esteem.

METHODS: From 2015 to 2017, 20 female patients were enrolled in our study and were randomized into two groups. Patients in Group A used a basic skin care regimen following hyaluronic acid filler and neurotoxin treatment, while those in Group B utilized the Nu-Derm® skin care system (Obagi Medical Products, Inc) afterwards. Each subject and the principal investigator filled out various assessments pre- and post-treatment to evaluate for change in skin quality (Fitzpatrick Wrinkle Assessment Scale [FWAS] and Skin Quality Assessments [SQA]), aesthetic appearance (Global Aesthetic Improvement Scale [GAIS]), patient satisfaction (Subject Satisfaction Assessment [SSA]), and self-esteem (State Self-Esteem Scale [SSES]).

RESULTS: Subjects in both treatment groups demonstrated significant improvement in skin quality, as illustrated in the change in FWAS and SQA scores, at 12 weeks after initiating full facial rejuvenation treatment. However, there were no significant differences in FWAS and SQA ratings between the treatment groups. Regarding aesthetic appearance, a statistically significant difference in GAIS scores between Groups A and B was observed at 6 weeks after treatment only. In evaluating for patient satisfaction and self-esteem, there were no significant differences in SSA and SSES ratings over time within each treatment group or between the treatment groups.

CONCLUSIONS: Our study confirms that facial rejuvenation therapy involving hyaluronic acid filler and neurotoxin injections combined with a topical skin treatment regimen leads to improvement in skin quality and aesthetic appearance as well as to patient satisfaction. Additional larger studies are needed to better delineate the most ideal combination facial rejuvenation therapy for optimizing patient appearance and satisfaction.

A Pilot Study Evaluating the Efficacy and Safety of ARTISS Human Fibrin Sealant in External Rhinoplasty.

BACKGROUND: Fibrin sealant application in rhytidectomy has previously demonstrated a reduction in adverse events and drainage volume. Fibrin sealant offers multiple potential benefits including decreasing downtime, reducing complication rates, and improving patient satisfaction. In this study, we evaluated the efficacy and safety of ARTISS [fibrin sealant (human)] in external rhinoplasty. METHODS: Nine healthy participants between the ages of 18 and 50 seeking external rhinoplasty completed this study. All subjects were randomized into control and treatment groups and then underwent external rhinoplasty, with only the treatment group receiving ARTISS [fibrin sealant (Human)] during surgery. Photographs were taken before surgery and 1 day, 1 week, 1 month, 3 months and 6 months after surgery and used in a blinded assessment of recovery time and esthetic improvement with ecchymosis and satisfaction scales. Subject recovery time, downtime, and self-esteem were evaluated at 1 day, 1 week, 1 month and 6 months after surgery. Recovery time was determined by live assessment of edema and ecchymosis using categorical scales. Subject downtime was assessed through a 30-day patient diary and a downtime questionnaire. Subject self-esteem was evaluated with the Heatherton & Polivy State Self-Esteem Scale. The degree of technical ease with the product was determined by the treating investigator with a 10-cm Visual Analog Scale. RESULTS: Patients treated with ARTISS intra-operatively reported significantly higher self-esteem 1 month and 6 months following external rhinoplasty. The ARTISS Easyspray™ Spray Set was rated as technically easy to administer. CONCLUSION: The use of ARTISS fibrin sealant in external rhinoplasties is a safe and easy method and may enhance patient self-esteem. Larger studies are warranted to either verify or challenge the validity of our findings. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Feedback modulation of neural network synchrony and seizure susceptibility by Mdm2-p53-Nedd4-2 signaling.

BACKGROUND: Neural network synchrony is a critical factor in regulating information transmission through the nervous system. Improperly regulated neural network synchrony is implicated in pathophysiological conditions such as epilepsy. Despite the awareness of its importance, the molecular signaling underlying the regulation of neural network synchrony, especially after stimulation, remains largely unknown. RESULTS: In this study, we show that elevation of neuronal activity by the GABA(A) receptor antagonist, Picrotoxin, increases neural network synchrony in primary mouse cortical neuron cultures. The elevation of neuronal activity triggers Mdm2-dependent degradation of the tumor suppressor p53. We show here that blocking the degradation of p53 further enhances Picrotoxin-induced neural network synchrony, while promoting the inhibition of p53 with a p53 inhibitor reduces Picrotoxin-induced neural network synchrony. These data suggest that Mdm2-p53 signaling mediates a feedback mechanism to fine-tune neural network synchrony after activity stimulation. Furthermore, genetically reducing the expression of a direct target gene of p53, Nedd4-2, elevates neural network synchrony basally and occludes the effect of Picrotoxin. Finally, using a kainic acid-induced seizure model in mice, we show that alterations of Mdm2-p53-Nedd4-2 signaling affect seizure susceptibility. CONCLUSION: Together, our findings elucidate a critical role of Mdm2-p53-Nedd4-2 signaling underlying the regulation of neural network synchrony and seizure susceptibility and reveal potential therapeutic targets for hyperexcitability-associated neurological disorders.
