Thin and Thinned Anterolateral Thigh Flaps for Upper Extremity Reconstruction.

Upper extremity reconstruction remains challenging due to the high functional and esthetic demands of this location. The anterolateral thigh (ALT) flap is a workhorse flap for microsurgical reconstruction of the upper extremity and can be elevated in various planes depending on desired thickness of the flap. Microsurgical reconstruction of the upper extremity often benefits from a thin flap that can resurface the extremity, which can provide improved functional and esthetic outcomes. This article reviews the anatomy, preoperative planning, and operative technique, as well as presents 4 cases to illustrate the outcomes and benefits of thin and thinned ALT flaps.

Palliative lower leg reconstruction.

Palliative care is a multidisciplinary field that aims to relieve physical pain and psychological suffering with the goal of improving quality of life rather than focusing on curing or prolonging life. Plastic surgeons may have a role in this near end-of-life care through palliative reconstruction. The use of palliative reconstruction has been frequently described in the setting of head and neck and thoracic malignancies However, there is a paucity in the literature about the role of palliative reconstruction in the lower extremity. In this review, we provide a summary of the current literature in support of the benefits of palliative reconstruction in the lower extremity as well as three case examples to demonstrate scenarios in which palliative lower extremity reconstruction may be used for select patients. In order to determine whether a patient may benefit from palliative reconstruction to merit its risks, the treatment goals and limitations must be assessed on a case-by-case basis in collaboration with the patient. Careful patient selection, focus on patient's ambulatory and personal goals, and minimizing donor site morbidity are important considerations in palliative reconstruction of the lower extremity. Together with a multidisciplinary approach, plastic surgeons can provide valuable contributions to improve the quality of life for certain palliative oncological patients by providing palliative reconstruction of the lower extremity.

Impact of an Electronic Health Record Pain Medication Prescribing Tool on Opioid Prescriptions for Postoperative Pain in Hand, Orthopedic, Plastic, and Spine Surgery Across a Health Care System.

PURPOSE: We hypothesized that a pain management prescribing tool embedded in the electronic health record system of a multihospital health care system would decrease prescription opioids for postoperative pain by hand, orthopedic, plastic, and spine surgeons. METHODS: A prescribing tool for postoperative pain was designed for hand, orthopedic, plastic, and spine surgeons and implemented into electronic discharge order sets in a 10-hospital health care system. Stakeholders were educated on tool use in person and/or by email on 2 occasions. A dashboard was created to monitor opioid pill quantities and morphine milligram equivalents (MMEs) prescribed. Overall compliance with the suggested opioid amounts was assessed for 20 months after tool implementation. A subgroup of 6 hand surgeons, one of whom was instrumental in designing the tool, were evaluated for MMEs prescribed, opioid refills, patient emergency room visits, and patient readmissions within 30 days after discharge. Comparisons in this subgroup were made from 12 months before to 15 months after tool implementation. RESULTS: The mean system-wide compliance with the suggested opioid pill quantities and MMEs prescribed in all 4 specialties improved by less than 5%. In the subgroup of hand surgeons, 5 of whom championed tool use, prescribed MMEs decreased by 10% during each of the 4 quarters before launching the tool and contracted an additional 26% in the first quarter after tool implementation. Opioid refills held steady at 5%, and there were no emergency room visits or readmissions within 30 days after discharge in this patient subgroup. CONCLUSIONS: The prescribing tool had a negligible impact on system-wide compliance with suggested prescription opioid pill quantities and MMEs. In a small group of surgeons who championed the use of the tool, there was a significant and sustained decline in MMEs prescribed without adversely impacting patient refills, emergency room visits, or readmissions. CLINICAL RELEVANCE: An electronic prescribing tool to assist surgeons in lowering opioid prescription pill quantities and MMEs may have a negligible impact on prescribing behavior in a multihospital health care system.

Vascularized Medial Femoral Condyle Periosteal Flaps With Allograft Bone for Distal Radius Giant Cell Tumors: A Case Report.

CASE: Distal radius reconstruction after giant cell tumor (GCT) resection is typically performed with free fibular flaps when a vascularized bone is needed. However, vascularized fibular flaps are contraindicated in patients with peroneal artery variants. We present 2 patients with GCTs of the radius and bilateral peronea arteria magna who underwent resection with wrist fusion using an allograft bone and vascularized free medial femoral condyle periosteal flaps. Both patients had excellent outcomes with minimal postoperative morbidity. CONCLUSION: Allograft bone with vascularized medial femoral condyle periosteal flaps is an effective option for reconstructing distal radius defects after GCT resection when conventional methods fail.

The Use of Botulinum Toxin to Prevent Anastomotic Thrombosis and Promote Flap Survival: A Bridge to Developing Clinical Studies.

BACKGROUND: Despite the possibility of using botulinum toxin to improve perfusion and prevent vasospasm, only a few studies have examined the use of botulinum toxin in the setting of flap surgery and thrombosis, and the mechanisms have not been fully explained. OBJECTIVE: The primary objective of this study was to provide a comprehensive review of the effectiveness of botulinum toxin in anastomotic thrombosis prevention and surgical flap survival to determine the value of conducting large-scale human trials. METHODS: Using the SYRCLE and CAMRADES criteria, a systematic review was performed. PubMed, Medline, EmBase, and the Cochrane Library were searched for studies that met our eligibility criteria. RESULTS: Twenty studies were included in the final selection. A total of 397 subjects were included. Eighteen studies used botulinum toxin type A alone, one used botulinum toxin type B alone, and only one used both botulinum toxin type A and botulinum toxin type B. The most commonly used injection technique was a preoperative intradermal injection. The most common procedure performed was a pedicled flap with random pattern skin flaps (65%). The mean injection dose was 28.17 ± 49.21 IU, whereas the mean reported injection time for studies using animal models was 7.4 ± 6.84 days. CONCLUSIONS: Similar mechanisms demonstrated in animal models may be replicable in humans, allowing botulinum toxin to be used to prolong flap survival. However, many factors, such as optimal injection techniques, dosages, and long-term outcomes of botulinum use in flap surgery, need to be further assessed before applying this to clinical practice.

Post-Mastectomy Pain Syndrome: Defining Perioperative Etiologies to Guide New Methods of Prevention for Plastic Surgeons.

From discussing the etiologies of post-mastectomy pain syndrome and potential methods of prevention, the next step is to create specific methods of prevention and to identify ways to measure their effects. With the increase in breast cancer related surgeries and increased survival after breast cancer patients, efforts must be made to prevent chronic pain and improve quality of life for these patients after surgery. The plastic surgeon, skilled in breast reconstruction and peripheral nerve reconstruction, may play a significant role in eliminating chronic pain after breast cancer related surgery.

Management of Sural Nerve Neuromas with Targeted Muscle Reinnervation.

Neuromas are a debilitating peripheral nerve problem due to aberrant axon sprouting and inflammation after nerve injury. The surgical management of neuromas has for a long time been up for debate, largely due to lack of consistent, reliable outcomes with any one technique. We have found success utilizing targeted muscle reinnervation, a technique originally described in amputees that re-routes the proximal ends of cut sensory nerve stumps into the distal ends of motor nerves to nearby muscles. In doing so, the sensory nerve ending can regenerate along the length of the motor nerve, giving it a place to go and something to do. In this report, we describe our technique specifically for targeted muscle reinnervation of sural nerve neuromas that is applicable to both amputees and to patients with intact limbs. Sural nerve neuromas can occur after sural nerve harvest for reconstructive procedures and particularly after lateral malleolar incisions for orthopedic access to the calcaneus. By re-routing the sural nerve into a motor nerve of the lateral gastrocnemius muscle, we are able to manage a variety of sural nerve neuromas presenting anywhere along the course of the sural nerve and in a variety of clinical settings.

Pediatric Tissue Expansion: Predictors of Premature Expander Removal in a Single Surgeon's Experience with 472 Expanders.

BACKGROUND: Tissue expansion is used for soft-tissue reconstruction in pediatric patients. The expansion process can be complicated by infection and extrusion, leading to premature expander removal. The aim of this study was to identify risk factors associated with premature expander removal caused by infection or extrusion in pediatric patients. METHODS: A retrospective study of pediatric patients who underwent tissue expansion performed by the senior author (R.J.R.) over a 12-year period was performed. Predictor variables included age, sex, race, indication, anatomical location, number of expanders, serial expansion, and expander size. Bivariate and multivariate analyses were performed to identify risk factors for premature expander removal. RESULTS: A total of 139 patients with 472 expanders were included in this study. Complications occurred with 78 expanders (16.5 percent). Premature expander removal caused by infection or exposure occurred with 51 expanders (10.8 percent). In terms of location, the highest rates of premature removal occurred in the lower extremity (20.0 percent) and scalp (16.3 percent). Multivariate analysis identified younger age (0 to 6 years compared with 13 to 17 years; OR, 3.98; 95 percent CI, 1.13 to 14.08; p = 0.03), greater number of expanders (OR, 1.45; 95 percent CI, 1.03 to 2.03; p = 0.03), and lower extremity location (OR, 4.27; 95 percent CI, 1.45 to 12.53; p = 0.008) were associated with an increased odds of premature expander removal. CONCLUSIONS: Expander removal occurred in approximately 10 percent of tissue expanders. Odds of premature removal is increased with younger age, greater number of expanders, and lower extremity location. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Longevity of Outcomes Following Reduction Mammoplasty.

Background: Reduction mammoplasty has been shown to provide wide-ranging benefits for patients including improved quality of life in terms of physical function and mental health. However, most existing studies have been limited to the 1-year postoperative period. The aim of this study was to investigate long-term outcomes after reduction mammoplasty. Methods: Patients who underwent reduction mammoplasty at a single institution were identified retrospectively and grouped into 3 categories based on time since surgery: (i) 5 to 10 years, (ii) 10 to 15 years, and (iii) more than 15 years. A telephone survey was administered to measure satisfaction and symptom relief following reduction mammoplasty. Results: A total of 124 patients completed the survey and were included in the study. The majority of patients in all 3 groups reported marked symptoms relief (75% vs 82% vs 82%, P = .84). Overall satisfaction after reduction mammoplasty was high in all 3 subgroups and did not significantly decrease over time (4.16 vs 3.97 vs 3.7, P = .216) despite high proportions of patients reporting an increase in breast size since surgery (40% vs 70% vs 51%, P = .0297). Conclusions: Overall, reduction mammoplasty has long-lasting benefits for patients with macromastia. Overwhelmingly, patients report satisfaction with the procedure and marked symptom relief that is sustained for as long as 15 years after surgery.

A 12-year review of patient-reported outcomes after reduction mammoplasty in patients with high body mass index.

Patients with increased body mass index (BMI) are often denied reduction mammoplasty due to concern for high morbidity. There is a paucity of evidence identifying high BMI as a predictor of poor long-term outcomes in reduction mammoplasty. In this study, we investigated the influence of BMI on long-term patient satisfaction following reduction mammoplasty.All patients undergoing reduction mammoplasty over a 12-year period at a single institution were included in the study. A retrospective chart review was conducted to extract demographics, operative data, and postoperative course including complications. Patients were classified into 4 categories based on BMI (normal (<25), overweight (25-29.9), obese (30-39.9), and morbidly obese (≥40)). Patient satisfaction was assessed using a customized survey which was administered over the phone. Only patients with complete medical records who participated in the survey were included.The 70 patients met the inclusion criteria for the study. Median time from surgery to survey was 6 years. Overall satisfaction after reduction mammoplasty was high, 5 on a 5-point Likert scale. The amount of breast tissue resected correlated with patient BMI (P <.01). There was no statistical difference in satisfaction across BMI classes. Furthermore, high BMI (obese, and morbidly obese) was not associated with higher postoperative complications (P = .70). Those with a high overall satisfaction score had a significantly greater self-reported aesthetic score compared to those with low and mid satisfied scores (P <.01).Following reduction mammoplasty, patients report high satisfaction which is sustained over several years. Obesity is not associated with a higher incidence of complications or lower satisfaction. Our data suggest that patients with a high BMI should not be denied reduction mammoplasty out of concern for higher complication rate or reduced patient satisfaction due to BMI alone, but reduction mammoplasty should be considered in the setting of overall health counseling.

Postoperative Outcomes in Obese Patients That Undergo Ventral Hernia Repair versus Ventral Hernia Repair with Concurrent Panniculectomy.

BACKGROUND: The safety of concurrent panniculectomy during ventral hernia repair remains a widely debated topic. This study aims to compare outcomes in obese patients who undergo ventral hernia repair with concurrent panniculectomy versus ventral hernia repair alone. METHODS: An 8-year retrospective cohort study was performed on obese patients who underwent ventral hernia repair. Patients were divided into those who underwent concurrent panniculectomy and those who did not. Postoperative complications were compared between these groups. RESULTS: A total of 223 patients were analyzed: 122 in the ventral hernia repair with concurrent panniculectomy group and 101 in the ventral hernia repair-only group. Median follow-up duration was 141 days. Patients in the ventral hernia repair with concurrent panniculectomy group had more surgical-site occurrences (57 percent versus 40 percent; p = 0.012). Both groups had similar rates of surgical-site occurrences that required an intervention (39 percent versus 31 percent; p = 0.179) and similar rates of hernia recurrence (23 percent versus 29 percent; p = 0.326). Multivariate analysis showed that concurrent panniculectomy increased the risk of surgical-site occurrences by two-fold; however, it did not increase the risk of surgical-site occurrences that required an intervention. CONCLUSIONS: The addition of a panniculectomy to ventral hernia repair increases surgical-site occurrences but does not increase complications that require an intervention. As such, ventral hernia repair with concurrent panniculectomy can be considered in obese patients with a symptomatic panniculus who wish to have a single-stage operation and the lifestyle benefits of a panniculectomy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Prevalence and Predictors of Chronic Health Conditions of Inmates Newly Admitted to Maximum Security Prisons.

This study estimated the prevalence of chronic medical conditions and risk predictors of 759 newly admitted inmates in two New York State maximum-security prisons. The most prevalent conditions were respiratory (34.1%), cardiovascular (17.4%), and sexually transmitted diseases (STD; 16.1%); least prevalent were HIV (3.6%), cancer (1.7%), and kidney disease (1.7%). Results of the multivariable logistic regression showed that females had higher risk for all conditions except cardiovascular and liver disease; individuals aged 40 years and older had significantly higher risk for all conditions except asthma and STD; non-Hispanic Black inmates had higher risk for respiratory disease and STD; cigarette smoking was associated with asthma; and obesity was significantly associated with diabetes, asthma, and cardiovascular conditions. These findings highlight the heavy burden of chronic illnesses among newly admitted inmates and the need to address adequate screening, prevention, and treatment services.

Concordance between medical records and interview data in correctional facilities.

BACKGROUND: Self- administered questionnaires or interviews and medical records are often used as sources of research data; thus it is essential to evaluate their concordance and reliability. The aim of this paper was to assess the concordance between medical and behavioral data obtained from medical records and interview questionnaires in two correctional facilities. METHODS: Medical record and interview data were compared for 679 inmates from one male and one female maximum security prison between April 2010 and February 2013. Gender non-stratified and gender-stratified analyses were conducted in SPSS to calculate the prevalence and kappa coefficient scores (κ) for medical (e.g., HIV, diabetes, hypertension) and behavioral (e.g., smoking, drug use, tattoos) conditions. Sensitivity/specificity between medical records and interview were calculated in the gender non-stratified data. RESULTS: In the gender non-stratified analysis, κ score for HIV, hepatitis C, diabetes, asthma, and history of tattoos had strong or good concordance (0.66-0.89). Hypertension, renal/kidney disease, cigarette smoking, antibiotic use in the last 6 months, and cocaine use ever were moderately correlated (0.49-0.57). Both history of any illicit drug use ever (0.36) and marijuana use ever (0.23) had poor concordance. Females had higher κ scores and prevalence rates than males overall. Medical conditions were reported more frequently in medical records and behavioral conditions had higher prevalence in interviews. Sensitivity for medical conditions in the combined facility data ranged from 50.0% to 86.0% and 48.2% to 85.3% for behavioral conditions whereas specificity ranged from 95.9% to 99.5% for medical conditions and 75.9% to 92.8% for behavioral conditions. CONCLUSION: Levels of agreement between medical records and self-reports varied by type of factor. Medical conditions were more frequently reported by chart review and behavioral factors more frequently by self-report. Data source used may need to be chosen carefully depending upon the type of information sought.

Cisplatin sensitivity mediated by WEE1 and CHK1 is mediated by miR-155 and the miR-15 family.

Resistance to platinum-based therapies arises by multiple mechanisms, including by alterations to cell-cycle kinases that mediate G(2)-M phase arrest. In this study, we conducted parallel high-throughput screens for microRNAs (miRNA) that could restore sensitivity to cisplatin-resistant cells, and we screened for kinases targeted by miRNAs that mediated cisplatin resistance. Overexpression of the cell-cycle kinases WEE1 and CHK1 occurred commonly in cisplatin-resistant cells. miRNAs in the miR-15/16/195/424/497 family were found to sensitize cisplatin-resistant cells to apoptosis by targeting WEE1 and CHK1. Loss-of-function and gain-of-function studies showed that miR-15 family members controlled the expression of WEE1 and CHK1. Supporting these results, we found that in the presence of cisplatin altering expression of miR-16 or related genes altered cell cycle distribution. Our findings reveal critical regulation of miRNAs and their cell-cycle-associated kinase targets in mediating resistance to cisplatin.

In vitro interactions between splenocytes and dansylamide dye-embedded nanoparticles detected by flow cytometry.

Engineered nanoparticles (NPs) possess a range of biological activity. In vitro methods for assessing toxicity and efficacy would be enhanced by simultaneous quantitative information on the behavior of NPs in culture systems and signals of cell response. We have developed a method for visualizing NPs within cells using standard flow-cytometric techniques and uniquely designed spherical siloxane NPs with an embedded (covalently bound) dansylamide dye. This method allowed NP visualization without obscuring detection of relevant biomarkers of cell subtype, activation state, and other events relevant to assessing bioactivity. We determined that NPs penetrated cells and induced a range of biological signals consistent with activation and costimulation. These results indicate that NPs may affect cell function at concentrations below those inducing cytotoxicity or apoptosis and demonstrate a novel method to image both localization of NPs and cell-level effects. FROM THE CLINICAL EDITOR: A method for visualizing NPs within cells using standard flow-cytometric techniques is reported in this paper. The novel method allowed NP visualization without obscuring detection of relevant biomarkers of cell subtype, activation state, and other events relevant to assessing bioactivity. NPs also induced a range of biological signals consistent with activation and costimulation.

Interrelationships of chromalveolates within a broadly sampled tree of photosynthetic protists.

The Chromalveolata "supergroup" is a massive assemblage of single-celled and multicellular protists such as ciliates and kelps that remains to be substantiated in molecular trees. Recent multigene analyses place chromalveolates into two major clades, the SAR (Stramenopiles, Alveolata, and Rhizaria) and the Cryptophyta+Haptophyta. Here we determined 69 new sequences from different chromalveolates to study the interrelationships of its constituent phyla. We included in our trees, the novel groups Telonemia and Katablepharidophyta that have previously been described as chromalvoleate allies. The best phylogenetic resolution resulted from a 6-protein (actin, alpha-tubulin, beta-tubulin, cytosolic HSP70, BIP HSP70, HSP90) and a 5-protein (lacking HSP90) alignment that validated the SAR and cryptophyte+haptophyte clades with the inclusion of telonemids in the former and katablepharids in the latter. We assessed the Plastidophila hypothesis that is based on EF2 data and suggest this grouping may be explained by horizontal gene transfers involving the EF2 gene rather than indicating host relationships.
