The Impact of Higher BMI on Wound Complications Following Adolescent Breast Reduction: A Retrospective Study of 1215 Cases.

BACKGROUND: Macromastia is a physically and psychologically distressing condition for adolescents. While reduction mammaplasty is often the best treatment, risk factors for adolescent wound complications remain unclear. This study aims to investigate the impact of obesity and other predictors of postoperative wound complications following adolescent reduction mammaplasty using a national database. METHODS: The 2012-2019 National Surgical Quality Improvement Program Pediatric (NSQIP-P) databases were reviewed to identify primary reduction mammaplasty encounters. World Health Organization Body Mass Index (BMI), alongside patient and case characteristics, were assessed for association for 30-day wound disruption or surgical site complications. Statistical analyses were performed to identify independent predictors for complications and determine a potential BMI cutoff for risk stratification. RESULTS: There were 1215 patients with an average age of 16.6 years. The average BMI was 30.7 kg/m2, and 593 (48.8%) patients were nonobese while 622 (51.2%) were obese. The incidence of complications was 5.27%. Independent predictors of complications included a BMI 35-39.9, BMI > 40, and an American Society of Anesthesiologists (ASA) Classification > 3. A receiver operating characteristic curve determined that a BMI of 34.6 can be a potential cutoff for increased complication risk. CONCLUSIONS: Higher obesity increases risk of wound complications; however, complication rates remain low. A BMI of 34.6 is a potential screening metric for counseling and monitoring patients. Reduction mammaplasty should remain a viable option as it can significantly improve quality of life.

Reduced Access to Acute Hand Care and Potential Role of Telemedicine in Tennessee During the COVID Pandemic.

INTRODUCTION: Previous studies have identified that there is limited, although expanding, access to acute hand care in Tennessee. Because of the rapid changes that occurred in health delivery and access during the coronavirus disease pandemic, we reassessed access to acute hand care, with particular interest in the utilization of telemedicine to assess if this increased access. METHOD: We surveyed Tennessee hospitals listed by the Tennessee Hospital Association on their management of hand trauma and availability of telemedicine programs. Census data including population demographics such as race, age, income, and county size were merged with the survey data. Descriptive analysis was performed comparing the 2021 cohort with the historic 2018 cohort and between counties that had hand care versus counties that had no hand care. RESULT: Survey response rate was 71.4% (n = 80 of 112). Telemedicine was used in 80% of the hospitals for other specialties but was not used for hand care. Overall, counties that offered hand trauma care reduced from 60% to 26% from 2018 to 2021 ( P < 0.001). This change was associated with a significant reduction of acute hand care among counties that were classified micropolitan (from 56.3% to 6.7%, P < 0.01). Percentage of hand specialists on staff and 24/7 specialists availability remained low and were similar to the availability in 2018. CONCLUSIONS: There was a decrease of acute hand care access in Tennessee during the coronavirus disease pandemic despite widespread utilization of telemedicine for other specialty consults. Expansion of telemedicine in acute hand care, targeted to micropolitan areas, may help to reduce variability in access to care.

Nerve blocks for occipital headaches: A systematic review and meta-analysis.

Migraine surgeons have identified six "trigger sites" where cranial nerve compression may trigger a migraine. This study investigates the change in headache severity and frequency following nerve block of the occipital trigger site. This PRISMA-compliant systematic review of five databases searched from database inception through May 2020 is registered under the PROSPERO ID: CRD42020199369. Only randomized controlled trials utilizing injection treatments for headaches with pain or tenderness in the occipital scalp were included. Pain severity was scored from 0 to 10. Headache frequency was reported as days per week. Included were 12 RCTs treating 586 patients of mean ages ranging from 33.7 to 55.8 years. Meta-analyses of pain severity comparing nerve blocks to baseline showed statistically significant reductions of 2.88 points at 5 to 20 min, 3.74 points at 1 to 6 weeks, and 1.07 points at 12 to 24 weeks. Meta-analyses of pain severity of nerve blocks compared with treatment groups of neurolysis, pulsed radiofrequency, and botulinum toxin type A showed similar headache pain severity at 1 to 2 weeks, and inferior improvements compared with the treatment groups after 2 weeks. Meta-analyses of headache frequency showed statistically significant reductions at 1 to 6-week follow-ups as compared with baseline and at 1 to 6 weeks as compared with inactive control injections. The severity and frequency of occipital headaches are reduced following occipital nerve blocks. This improvement is used to predict the success of migraine surgery. Future research should investigate spinous process injections with longer follow-up.

Implantable, Bioresorbable Radio Frequency Resonant Circuits for Magnetic Resonance Imaging.

Magnetic resonance imaging (MRI) is widely used in clinical care and medical research. The signal-to-noise ratio (SNR) in the measurement affects parameters that determine the diagnostic value of the image, such as the spatial resolution, contrast, and scan time. Surgically implanted radiofrequency coils can increase SNR of subsequent MRI studies of adjacent tissues. The resulting benefits in SNR are, however, balanced by significant risks associated with surgically removing these coils or with leaving them in place permanently. As an alternative, here the authors report classes of implantable inductor-capacitor circuits made entirely of bioresorbable organic and inorganic materials. Engineering choices for the designs of an inductor and a capacitor provide the ability to select the resonant frequency of the devices to meet MRI specifications (e.g., 200 MHz at 4.7 T MRI). Such devices enhance the SNR and improve the associated imaging capabilities. These simple, small bioelectronic systems function over clinically relevant time frames (up to 1 month) at physiological conditions and then disappear completely by natural mechanisms of bioresorption, thereby eliminating the need for surgical extraction. Imaging demonstrations in a nerve phantom and a human cadaver suggest that this technology has broad potential for post-surgical monitoring/evaluation of recovery processes.

Outcomes of Surgical Treatment of Migraines: A Systematic Review & Meta-Analysis.

Background: Migraine surgery at 1 of 6 identified "trigger sites" of a target cranial sensory nerve has rapidly grown in popularity since 2000. This study summarizes the effect of migraine surgery on headache severity, headache frequency, and the migraine headache index score which is derived by multiplying migraine severity, frequency, and duration. Materials and Methods: This is a PRISMA-compliant systematic review of 5 databases searched from inception through May 2020 and is registered under the PROSPERO ID: CRD42020197085. Clinical trials treating headaches with surgery were included. Risk of bias was assessed in randomized controlled trials. Meta-analyses were performed on outcomes using a random effects model to determine the pooled mean change from baseline and when possible, to compare treatment to control. Results: 18 studies met criteria including 6 randomized controlled trials, 1 controlled clinical trial, and 11 uncontrolled clinical trials treated 1143 patients with pathologies including migraine, occipital migraine, frontal migraine, occipital nerve triggered headache, frontal headache, occipital neuralgia, and cervicogenic headache. Migraine surgery reduced headache frequency at 1 year postoperative by 13.0 days per month as compared to baseline (I2 = 0%), reduced headache severity at 8 weeks to 5 years postoperative by 4.16 points on a 0 to 10 scale as compared to baseline (I2 = 53%), and reduced migraine headache index at 1 to 5 years postoperative by 83.1 points as compared to baseline (I2 = 2%). These meta-analyses are limited by a small number of studies that could be analyzed, including studies with high risk of bias. Conclusion: Migraine surgery provided a clinically and statistically significant reduction in headache frequency, severity, and migraine headache index scores. Additional studies, including randomized controlled trials with low risk-of-bias should be performed to improve the precision of the outcome improvements.

Historique: Le traitement de la migraine à l'une des six « zones gâchettes ¼ établies d'un nerf crânien sensoriel cible ont rapidement gagné en popularité depuis 2000. La présente étude résume l'effet du traitement chirurgical de la migraine sur la gravité et la fréquence des céphalées et sur le score de migraine obtenu par la multiplication de la gravité, de la fréquence et de la durée des migraines. Matériel et méthodologie: La présente analyse systématique de cinq bases de données fouillées depuis leur création jusqu'à mai 2020 respecte la liste PRISMA et est enregistrée sous le numéro d'identification CRD42020197085 de PROSPERO. Les chercheurs ont retenu les études cliniques sur le traitement des céphalées par des interventions chirurgicales. Ils ont évalué le risque de biais des études aléatoires et contrôlées. Ils ont également effectué des méta-analyses des résultats au moyen d'un modèle à effets aléatoires pour déterminer le changement moyen regroupé par rapport à l'état de référence et, dans la mesure du possible, pour comparer des sujets traités à des sujets témoins. Résultats: Au total, 18 études respectaient les critères, y compris six études aléatoires et contrôlées, une étude clinique contrôlée, et 11 études non contrôlées auprès de 1 143 patients ayant des pathologies incluant la migraine, la migraine occipitale, la migraine frontale, la céphalée occipitale, la céphalée frontale, la névralgie occipitale et la céphalée cervicogénique. Par rapport à l'état de départ, le traitement chirurgical de la migraine avait réduit la fréquence des céphalées de 13,0 jours par mois (I2 = 0%) un an après l'opération, la gravité des céphalées de 4,16 points sur une échelle de 0 à 10 de huit semaines à cinq ans après l'opération (I2 = 53%) et le score de migraine de 83,1 points de un à cinq ans après l'opération (I2 = 2%). Ces méta-analyses sont limitées par le petit nombre d'études pouvant être analysées, y compris des études comportant de forts risques de biais. Conclusion: Le traitement chirurgical de la migraine assure une diminution cliniquement et statistiquement significative de la fréquence et de la gravité des céphalées, ainsi que des scores de migraine. D'autres études, y compris des études aléatoires et contrôlées comportant un faible risque de biais, devront être exécutées pour mieux préciser les améliorations aux résultats cliniques.

Antibiotic Prophylaxis and Infectious Complications in Isolated Gunshot Wounds to the Upper Extremity.

BACKGROUND: Prophylactic antibiotics are variably prescribed after isolated upper extremity gunshot wounds (UE GSWs). The risk of infection and factors influencing prescribing practice remain poorly understood, and clinical practice guidelines are lacking. METHODS: Adults with isolated UE GSWs over a 10-year period were included. Medical records were reviewed for demographic and injury variables, comorbidities, surgical treatments, antibiotic administration, infectious complications, and follow-up duration. Infection rate was calculated. Bivariate and multivariable linear regression analyses were used to identify patient-related and injury-related factors predictive of prophylactic antibiotic prescription. RESULTS: A total of 281 patients were eligible for inclusion. Prophylactic antibiotics were prescribed at discharge for 111 patients (40%). Multivariable analysis revealed that patients with more distal injuries and ballistic fractures were significantly more likely to receive prophylactic antibiotics. Of patients with at least 30-day postinjury follow-up, 6% developed infections. CONCLUSION: Prophylactic antibiotic administration after UE GSWs was inconsistent but more common in patients with ballistic fractures and injuries in the hand. The overall incidence of infection was found to lie between 3% and 6%. The rate of infection in the antibiotic prophylaxis (2%-6%) group was similar to that in the no-antibiotic (5%-7%) group, suggesting that antibiotic prophylaxis may not have a large impact on infectious risk. However, because this study is nonrandomized, and because this study is underpowered for multivariable modeling of infectious risk, it remains possible that subgroups of this population may still benefit from antibiotic prophylaxis.

Postamputation Residual Limb Pain Severity and Prevalence: A Systematic Review and Meta-Analysis.

Background: Individuals with an extremity amputation are predisposed to persistent pain that reduces their quality of life. Residual limb pain is defined as pain that is felt in the limb after amputation. Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic review of 5 databases from inception to June 2020 was performed and is registered under the PROSPERO ID: CRD42020199297. Included studies were clinical trials with residual limb pain assessed at a minimum follow-up of 1 week. Meta-analyses of residual limb pain prevalence and severity were performed with subgroups of extremity and amputation etiology. Results: Twenty clinical trials met criteria and reported on a total of 1347 patients. Mean patient ages ranged from 38 to 77. Residual limb pain prevalence at 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years, respectively, was 50%, 11%, 23%, 27%, 22%, and 24%. Mean residual limb pain severity at the 6 months or longer follow-up was 4.19 out of 10 for cancer amputations, 2.70 for traumatic amputations, 0.47 for vasculopathy amputations, 1.01 for lower extremity amputations, and 3.56 for upper extremity amputations. Conclusions: Residual limb pain severity varies according to the etiology of amputation and is more common after upper extremity amputation than lower extremity amputations. The most severe pain is reported by patients undergoing amputations due to cancer, followed by traumatic amputations, while vascular amputation patients report lower pain severity. Promising methods of reducing long-term pain are preoperative pain control, nerve or epidural blocks, use of memantine, calcitonin-containing blocks, and prophylactic nerve coaptations.

Contexte: Les personnes subissant une amputation d'un membre sont prédisposées à des douleurs persistantes réduisant leur qualité de vie. La douleur du membre résiduel est définie comme étant la douleur ressentie dans le membre après l'amputation. Méthodes: Une revue systématique conforme à PRISMA de 5 bases de données depuis leur création jusqu'en juin 2020 a été effectuée et enregistrée sous l'ID PROSPERO: CRD42020199297. Les études incluses étaient des essais cliniques avec douleur du membre résiduel évaluée à un suivi minimum de 1 semaine. Des méta-analyses sur la prévalence et la sévérité de la douleur du membre résiduel ont été réalisées avec des sous-groupes en fonction du membre et de la cause de l'amputation. Résultats: 20 essais cliniques satisfaisaient les critères et portaient sur un total de 1347 patients. Les âges moyens des patients étaient compris entre 38 et 77 ans. La prévalence de la douleur du membre résiduel à 1 semaine, 1 mois, 3 mois, 6 mois, 1 an et 2 ans était, respectivement, de 50%, 11%, 23%, 27%, 22%, et 24%. La sévérité moyenne de la douleur du membre résiduel aux suivis de 6 mois ou plus a été de 4,19 sur 10 pour les amputations pour cancer, 2,70 pour les amputations post traumatisme, 0,47 pour les amputations liées à une vasculopathie, 1,01 pour les amputations du membre inférieur et 3,56 pour les amputations du membre supérieur. Conclusions: La sévérité de la douleur du membre résiduel varie en fonction du motif de l'amputation, et elle est plus fréquente après une amputation du membre supérieur qu'après des amputations du membre inférieur. La douleur la plus sévère a été décrite par des patients subissant une amputation à cause d'un cancer, suivie des amputations traumatiques, alors que les patients ayant subi une amputation pour cause vasculaire signalent une sévérité plus faible. Des méthodes prometteuses de réduction de la douleur à long terme sont le contrôle préopératoire de la douleur, les blocs nerveux et épiduraux, l'utilisation de la mémantine, de blocs contenant de la calcitonine et la coaptation prophylactique des nerfs.

Nationwide Estimates of Gender-Affirming Chest Reconstruction in the United States, 2016-2019.

BACKGROUND: Section 1557 of the Affordable Care Act, introduced in 2016, increased access to gender-affirming surgeries for transgender and gender diverse individuals. Masculinizing chest reconstruction (e.g., mastectomy) and feminizing chest reconstruction (e.g., augmentation mammaplasty), often outpatient procedures, are the most frequently performed gender-affirming surgeries. However, there is a paucity of information about the demographics of patients who undergo gender-affirming chest reconstruction. OBJECTIVES: The authors sought to investigate the incidence, demographics, and spending for ambulatory gender-affirming chest reconstruction utilizing nationally representative data from 2016 to 2019. METHODS: Employing the Nationwide Ambulatory Surgery Sample, the authors identified patients with an International Classification of Diseases diagnosis code of gender dysphoria who underwent chest reconstruction between 2016 and 2019. Demographic and clinical characteristics were recorded for each encounter. RESULTS: A weighted estimate of 21,293 encounters for chest reconstruction were included (17,480 [82.1%] masculinizing and 3813 [27.9%] feminizing). Between 2016 and 2019, the number of chest surgeries per 100,000 encounters increased by 143.2% from 27.3 to 66.4 (P < 0.001). A total 12,751 (59.9%) chest surgeries were covered by private health insurance, 6557 (30.8%) were covered by public health insurance, 1172 (5.5%) were self-pay, and 813 (3.8%) had other means of payment. The median total charges were $29,887 (IQR, $21,778-$43,785) for chest reconstruction overall. Age, expected primary payer, patient location, and median income varied significantly by race (P < 0.001). CONCLUSIONS: Gender-affirming chest reconstructions are on the rise, and surgeons must understand the background and needs of transgender and gender diverse patients who require and choose to undergo surgical transitions.

Donor activation focused rehabilitation approach to hand closing nerve transfer surgery in individuals with cervical level spinal cord injury.

STUDY DESIGN: Case Series. OBJECTIVES: To describe the donor activation focused rehabilitation approach (DAFRA) in the setting of the hand closing nerve transfers in cervical spinal cord injury (SCI) so that therapists may apply it to treatment of individuals undergoing this procedure. SETTING: United States of America-Academic Level 1 Trauma Center. METHODS: We reviewed the records of individuals with cervical SCI who underwent nerve transfer to restore hand closing and post-surgery DAFRA therapy at our institution. The three post-surgery phases of DAFRA included (1) early phase (0-12 months) education, limb preparation, and donor activation exercises, (2) middle phase (12-24 months) volitional recipient muscle activation and (3) late phase (18 + months) strengthening and incorporation of motion in activities of daily living. RESULTS: Subtle gains in hand closing were first observed at a mean of 8.4 months after hand closing nerve transfer surgery. Remarkable improvements including discontinuation of assistive devices, independence with feeding and urinary function, and measurable grip were observed. Function continued to improve slowly for one to two more years. CONCLUSIONS: A deliberate, slow-paced (monthly for >2 years post-surgery) and incremental therapy program-DAFRA-can be used to improve outcomes after nerve transfer to restore hand closing in cervical SCI.
