An Updated Analysis of Body Contouring Malpractice Cases.

INTRODUCTION: Body contouring procedures are commonly performed in the United States for patients seeking to sculpt specific areas of their bodies. The aim of this study was to provide an updated analysis of the factors that influence medical malpractice litigation surrounding body contouring surgery. METHODS: The following terms were used to search the Westlaw Campus Legal research Database for cases with earliest documentation after January 2013: ("contouring" OR "abdominoplasty" OR "liposuction" OR "tummy tuck" OR "body lift" OR "thigh lift" OR "arm lift" OR "brachioplasty" OR "thighplasty" OR "lipectomy" OR "panniculectomy") AND "surgery" AND "medical malpractice." Cases were only included if there was a complaint of medical malpractice subsequent to a body contouring procedure, and details of the cases were provided. Information was collected on the location of the lawsuit, the earliest year of available case documentation, patient demographics, procedure(s) performed, alleged injury, specialty involvement, and verdicts. RESULTS: A total of 32 cases were included in the study. Most of the patients involved in the cases were women (n = 30, 93.8%) and alive (n = 28, 87.5%). New York state had the most cases (n = 7, 21.9%). Abdominoplasty (56.3%), liposuction (53.1%), and buttock augmentations (15.6%) were the most common procedures. Plastic surgeons were involved in 93.8% (n = 30) of the cases, and anesthesia, emergency medicine, dermatology, and oncology were also involved. Claims of malpractice most often discussed negligent technique (71.9%) and poor postoperative management (62.5%). Common postoperative complications were infection/sepsis (40.6%), scarring (31.3%), and emotional distress/prolonged pain (31.3%). One available ruling was in favor of the plaintiff. CONCLUSION: Although many of the cases in this analysis cited negligent technique, none were founded in their argument. Because involvement in these cases can place a burden on attending physicians, clear expectations of postoperative infections, scarring, and prolonged pain should be addressed during the informed consent process.

Reduced neuronal population in the dorsolateral prefrontal cortex in infant macaques infected with simian immunodeficiency virus (SIV).

Pediatric HIV infection remains a global health crisis with an estimated 150,000 new mother-to-child (MTCT) infections each year. Antiretroviral therapy (ART) has improved childhood survival, but only an estimated 53% of children worldwide have access to treatment. Adding to the health crisis is the neurological impact of HIV on the developing brain, in particular cognitive and executive function, which persists even when ART is available. Imaging studies suggest structural, connectivity, and functional alterations in perinatally HIV-infected youth. However, the paucity of histological data limits our ability to identify specific cortical regions that may underlie the clinical manifestations. Utilizing the pediatric simian immunodeficiency virus (SIV) infection model in infant macaques, we have previously shown that early-life SIV infection depletes the neuronal population in the hippocampus. Here, we expand on these previous studies to investigate the dorsolateral prefrontal cortex (dlPFC). A total of 11 ART-naïve infant rhesus macaques (Macaca mulatta) from previous studies were retrospectively analyzed. Infant macaques were either intravenously (IV) inoculated with highly virulent SIVmac251 at ~1 week of age and monitored for 6-10 weeks or orally challenged with SIVmac251 from week 9 of age onwards with a monitoring period of 10-23 weeks post-infection (19-34 weeks of age), and SIV-uninfected controls were euthanized at 16-17 weeks of age. Both SIV-infected groups show a significant loss of neurons along with evidence of ongoing neuronal death. Oral- and IV-infected animals showed a similar neuronal loss which was negatively correlated to chronic viremia levels as assessed by an area under the curve (AUC) analysis. The loss of dlPFC neurons may contribute to the rapid neurocognitive decline associated with pediatric HIV infection.

Fabrication of a Toe Prosthesis with Paintable and Interchangeable Nail: A Clinical Report.

This report describes the treatment of a 44-year-old woman with history of left great toe amputation due to surgical complications from metatarsophalangeal joint fusion procedure. The fabrication of a prosthetic great toe with interchangeable nail that is paintable is described in detail. This prosthetic demonstrates that the clinical and laboratory techniques used in fabrication of traditional maxillofacial prosthetics can be adapted for the fabrication of somatic prosthetics to enhance quality of life.

Sentinel lymph node biopsy for management of the N0 neck in oral cavity squamous cell carcinoma.

BACKGROUND AND OBJECTIVES: The management of the clinically N0 (cN0) neck is controversial for early stage squamous cell carcinoma of the oral cavity (OSCC). This paper represents a single institution series analyzing the efficacy of sentinel lymph node biopsy (SNB) for early stage oral cavity cancers. METHODS: From 2005 to 2017, 108 patients with cN0 OSCC were treated with primary resection and SNB. Patients with positive biopsy results proceeded to neck dissection with or without adjuvant chemoradiotherapy. Mean follow-up for the entire cohort was 50.8 months (range: 8-147 months). Clinically, 56 patients were T1N0, 49 patients were T2N0, and three patients were T3N0 or greater. RESULTS: Disease-specific survival was 93% within the entire cohort. Sentinel lymph nodes were identified in 95.4% of patients. Twenty one patients had a positive biopsy. There were seven false-negative biopsies. The overall rate of nodal disease was 26%. Accuracy of node biopsy was 93%, with sensitivity of 75%, and negative predictive value of 91%. Recurrence rate was 19% (20/108), with an overall survival of 60% in this subgroup. CONCLUSION: SNB is a safe, effective, and well tolerated method for staging cN0 OSCC.

CXCR4 Cardiac Specific Knockout Mice Develop a Progressive Cardiomyopathy.

Activation of multiple pathways is associated with cardiac hypertrophy and heart failure. We previously published that CXCR4 negatively regulates ß-adrenergic receptor (ß-AR) signaling and ultimately limits ß-adrenergic diastolic (Ca2+) accumulation in cardiac myocytes. In isolated adult rat cardiac myocytes; CXCL12 treatment prevented isoproterenol-induced hypertrophy and interrupted the calcineurin/NFAT pathway. Moreover; cardiac specific CXCR4 knockout mice show significant hypertrophy and develop cardiac dysfunction in response to chronic catecholamine exposure in an isoproterenol-induced (ISO) heart failure model. We set this study to determine the structural and functional consequences of CXCR4 myocardial knockout in the absence of exogenous stress. Cardiac phenotype and function were examined using (1) gated cardiac magnetic resonance imaging (MRI); (2) terminal cardiac catheterization with in vivo hemodynamics; (3) histological analysis of left ventricular (LV) cardiomyocyte dimension; fibrosis; and; (4) transition electron microscopy at 2-; 6- and 12-months of age to determine the regulatory role of CXCR4 in cardiomyopathy. Cardiomyocyte specific-CXCR4 knockout (CXCR4 cKO) mice demonstrate a progressive cardiac dysfunction leading to cardiac failure by 12-months of age. Histological assessments of CXCR4 cKO at 6-months of age revealed significant tissue fibrosis in knockout mice versus wild-type. The expression of atrial naturietic factor (ANF); a marker of cardiac hypertrophy; was also increased with a subsequent increase in gross heart weights. Furthermore, there were derangements in both the number and the size of the mitochondria within CXCR4 cKO hearts. Moreover, CXCR4 cKO mice were more sensitive to catocholamines, their response to ß-AR agonist challenge via acute isoproterenol (ISO) infusion demonstrated a greater increase in ejection fraction, dp/dtmax, and contractility index. Interestingly, prior to ISO infusion, there were significant differences in baseline hemodynamics between the CXCR4 cKO compared to littermate controls. However, upon administering ISO, the CXCR4 cKO responded in a robust manner overcoming the baseline hemodynamic deficits reaching WT values supporting our previous data that CXCR4 negatively regulates ß-AR signaling. This further supports that, in the absence of the physiologic negative modulation, there is an overactivation of down-stream pathways, which contribute to the development and progression of contractile dysfunction. Our results demonstrated that CXCR4 plays a non-developmental role in regulating cardiac function and that CXCR4 cKO mice develop a progressive cardiomyopathy leading to clinical heart failure.

A Draft Genome Sequence of the Burrowing Nematode Radopholus similis.

Radopholus similis also known as the burrowing nematode is a devastating pest of banana (Musa spp.) and many economically important crops and ornamentals. In this publication, we present the genome assembly of R. similis.

Hippocampal neuron populations are reduced in vervet monkeys with fetal alcohol exposure.

Prenatal exposure to beverage alcohol is a major cause of mild mental retardation and developmental delay. In nonendangered alcohol-preferring vervet monkeys, we modeled the most common nondysmorphic form of fetal alcohol syndrome disorder with voluntary drinking during the third trimester of pregnancy. Here, we report significant numerical reductions in the principal hippocampal neurons of fetal alcohol-exposed (FAE) offspring, as compared to age-matched, similarly housed conspecifics with isocaloric sucrose exposure. These deficits, particularly marked in CA1 and CA3, are present neonatally and persist through infancy (5 months) and juvenile (2 years) stages. Although the volumes of hippocampal subdivisions in FAE animals are not atypical at birth, by age 2, they are only 65-70% of those estimated in age-matched controls. These data suggest that moderate, naturalistic alcohol consumption during late pregnancy results in a stable loss of hippocampal neurons and a progressive reduction of hippocampal volume.

Interpolation of diffusion weighted imaging datasets.

Diffusion weighted imaging (DWI) is used to study white-matter fibre organisation, orientation and structural connectivity by means of fibre reconstruction algorithms and tractography. For clinical settings, limited scan time compromises the possibilities to achieve high image resolution for finer anatomical details and signal-to-noise-ratio for reliable fibre reconstruction. We assessed the potential benefits of interpolating DWI datasets to a higher image resolution before fibre reconstruction using a diffusion tensor model. Simulations of straight and curved crossing tracts smaller than or equal to the voxel size showed that conventional higher-order interpolation methods improved the geometrical representation of white-matter tracts with reduced partial-volume-effect (PVE), except at tract boundaries. Simulations and interpolation of ex-vivo monkey brain DWI datasets revealed that conventional interpolation methods fail to disentangle fine anatomical details if PVE is too pronounced in the original data. As for validation we used ex-vivo DWI datasets acquired at various image resolutions as well as Nissl-stained sections. Increasing the image resolution by a factor of eight yielded finer geometrical resolution and more anatomical details in complex regions such as tract boundaries and cortical layers, which are normally only visualized at higher image resolutions. Similar results were found with typical clinical human DWI dataset. However, a possible bias in quantitative values imposed by the interpolation method used should be considered. The results indicate that conventional interpolation methods can be successfully applied to DWI datasets for mining anatomical details that are normally seen only at higher resolutions, which will aid in tractography and microstructural mapping of tissue compartments.

Pectoralis major myocutaneous flap for reconstruction of circumferential pharyngeal defects.

BACKGROUND: A 270-degree partially tubed pectoralis major myocutaneous flap (PMMF) is an excellent option for total circumferential pharyngoesophageal defects in patients who are not candidates for more complex reconstructions. METHODS: Patients undergoing circumferential pharyngoesophageal reconstruction with partially tubed PMMF were reviewed. End points were stricture, fistula, resumption of oral intake, perioperative death, and recurrence. RESULTS: Eleven patients underwent 270-degree PMMF for reconstruction: 6 (55%) were men and 5 (45%) were women (mean, 62 years; range, 42-78 years). Three patients (27%) developed fistulas and 2 (18%) developed stenosis. Ten patients (91%) were able to resume adequate nutrition via oral intake. There were no perioperative deaths. CONCLUSIONS: Patients with severe comorbidities, metastatic disease, a lack of donor vessels, or a potentially hostile abdomen may not be ideal candidates for free tissue transfer. For these patients, partially tubed PMMF using the prevertebral fascia provides a reliable alternative for reconstruction with excellent functional results.

Carcinoma Cuniculatum: A Rare Malignancy With Unique Diagnostic Dilemmas.

Carcinoma cuniculatum is an extremely rare and often indolent cancer that can mimic a benign process, such as osteomyelitis or odontogenic infections. This results in a definitive diagnosis that is delayed. To complicate the evaluation of this uncommon neoplasm, biopsies are often misinterpreted secondary to an incorrectly obtained tissue sample. Incisional biopsy needs to be done in a specific manner with a high degree of clinical suspicion incorporated into the patient assessment for the most accurate diagnosis. Local and distant failure rates are low with aggressive surgical resection and surgery upfront remains the treatment of choice when feasible. We present two cases that highlight the difficulty in accurate diagnosis and management of these rare cancers.

Developing an Inclusive Generation of HIV Researchers Through Diversity and Community.

BACKGROUND: The DC Center for AIDS Research Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI) is designed to increase the number of underrepresented minority (URM) students engaged in HIV research by providing an opportunity to participate in research and developing a sense of self-efficacy and community. SETTING: Currently in its second year, the program provides high school (HS) and undergraduate (UG) URM students (CFAR scholars) HIV mentored-research opportunities, and a range of professional development, outreach, and volunteer opportunities meant to build a sense of community and promote self-efficacy. A near-peer mentoring program, led by graduate students leads (GSL), was added in the second year to enhance community building. METHODS: We conducted a descriptive evaluation of the program using both individual surveys distributed to program participants and a series of focus groups conducted with current HS and UG scholars, and GSL. RESULTS: Based on initial evaluation results, this program was able to recruit a diverse group of scholars who have persisted in mentored HIV research, increased interests in pursuing careers in HIV research and care, developed research competencies, and increased confidence and self-efficacy. CONCLUSION: Our long-term goal is to build on this program by annually recruiting new cohorts, providing multiyear support to UG scholars, and developing additional evaluation tools to measure program impacts on the career trajectories of program participants, and identify program characteristics associated with those impacts.

Twelve Steps to Financial Freedom for Plastic Surgeons.

Financial stress and lack of financial well-being are significant contributors to physician burnout. Many trainees believe little can contribute to developing financial freedom during their training years. However, residency is a pivotal moment in a young attending's life; strategic financial steps taken during this time can lead to a path of financial freedom and well-being for years to come. Methods: We introduce 12 effective financial steps physicians can take at the start of their careers. These essential steps were compiled both anecdotally and from published financial resources such as White Coat Investigator and the Millionaire Next Door. Steps include building your "why," becoming financially educated, eliminating debt, attaining insurance, optimizing contracts, awareness of self-net worth, budgeting, maximizing investment strategies, smart investing, wise spending, K.I.S.S, and creating a personal financial plan. Results: As an example, an IRA is a retirement account set up by you, and to take advantage of the tax benefits, you must have a modified adjusted gross income of less than $124,000 as a single tax filer for 2022. Most physicians are compensated at a rate higher than this; however, there is a legal loophole to take advantage of to allow earners to still contribute to a Roth IRA that is discussed. Conclusions: Financial education is the first step toward a path to financial success in a young physician's life. Implementation of these 12 financial steps early in a physician's career will enrich one's financial freedom and well-being.

Centers for AIDS Research (CFAR) Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI): Developing Career Pathways for Early-Stage Scholars From Racial and Ethnic Groups Underrepresented in HIV Science and Medicine.

BACKGROUND: There is an urgent need to increase diversity among scientific investigators in the HIV research field to be more reflective of communities highly affected by the HIV epidemic. Thus, it is critical to promote the inclusion and advancement of early-stage scholars from racial and ethnic groups underrepresented in HIV science and medicine. METHODS: To widen the HIV research career pathway for early-stage scholars from underrepresented minority groups, the National Institutes of Health supported the development of the Centers for AIDS Research (CFAR) Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI). This program was created through partnerships between CFARs and Historically Black Colleges and Universities and other Minority Serving Institutions throughout the United States. RESULTS: Seventeen CFARs and more than 20 Historically Black Colleges and Universities and Minority Serving Institutions have participated in this initiative to date. Programs were designed for the high school (8), undergraduate (13), post baccalaureate (2), graduate (12), and postdoctoral (4) levels. Various pedagogical approaches were used including didactic seminar series, intensive multiday workshops, summer residential programs, and mentored research internship opportunities. During the first 18 months of the initiative, 257 student scholars participated in CDEIPI programs including 150 high school, 73 undergraduate, 3 post baccalaureate, 27 graduate, and 4 postdoctoral students. CONCLUSION: Numerous student scholars from a wide range of educational levels, geographic backgrounds, and racial and ethnic minority groups have engaged in CDEIPI programs. Timely and comprehensive program evaluation data will be critical to support a long-term commitment to this unique training initiative.

Adaptive neuroplastic responses in early and late hemispherectomized monkeys.

Behavioural recovery in children who undergo medically required hemispherectomy showcase the remarkable ability of the cerebral cortex to adapt and reorganize following insult early in life. Case study data suggest that lesions sustained early in childhood lead to better recovery compared to those that occur later in life. In these children, it is possible that neural reorganization had begun prior to surgery but was masked by the dysfunctional hemisphere. The degree of neural reorganization has been difficult to study systematically in human infants. Here we present a 20-year culmination of data on our nonhuman primate model (Chlorocebus sabeus) of early-life hemispherectomy in which behavioral recovery is interpreted in light of plastic processes that lead to the anatomical reorganization of the early-damaged brain. The model presented here suggests that significant functional recovery occurs after the removal of one hemisphere in monkeys with no preexisting neurological dysfunctions. Human and primate studies suggest a critical role for subcortical and brainstem structures as well as corticospinal tracts in the neuroanatomical reorganization which result in the remarkable behavioral recovery following hemispherectomy. The non-human primate model presented here offers a unique opportunity for studying the behavioral and functional neuroanatomical reorganization that underlies developmental plasticity.

Dose-Related Reduction in Hippocampal Neuronal Populations in Fetal Alcohol Exposed Vervet Monkeys.

Fetal alcohol spectrum disorder (FASD) is a chronic debilitating condition resulting in behavioral and intellectual impairments and is considered the most prevalent form of preventable mental retardation in the industrialized world. We previously reported that 2-year-old offspring of vervet monkey (Chlorocebus sabeus) dams drinking, on average, 2.3 ± 0.49 g ethanol per Kg maternal body weight 4 days per week during the last third of pregnancy had significantly lower numbers of CA1 (-51.6%), CA2 (-51.2%) and CA3 (-42.8%) hippocampal neurons, as compared to age-matched sucrose controls. Fetal alcohol-exposed (FAE) offspring also showed significantly lower volumes for these structures at 2 years of age. In the present study, we examined these same parameters in 12 FAE offspring with a similar average but a larger range of ethanol exposures (1.01-2.98 g/Kg/day; total ethanol exposure 24-158 g/Kg). Design-based stereology was performed on cresyl violet-stained and doublecortin (DCX)-immunostained sections of the hippocampus. We report here significant neuronal deficits in the hippocampus with a significant negative correlation between daily dose and neuronal population in CA1 (r2 = 0.486), CA2 (r2 = 0.492), and CA3 (r2 = 0.469). There were also significant correlations between DCX population in the dentate gyrus and daily dose (r2 = 0.560). Both correlations were consistent with linear dose-response models. This study illustrates that neuroanatomical sequelae of fetal ethanol exposure are dose-responsive and suggests that there may be a threshold for this effect.

Sequence and genetic map of Meloidogyne hapla: A compact nematode genome for plant parasitism.

We have established Meloidogyne hapla as a tractable model plant-parasitic nematode amenable to forward and reverse genetics, and we present a complete genome sequence. At 54 Mbp, M. hapla represents not only the smallest nematode genome yet completed, but also the smallest metazoan, and defines a platform to elucidate mechanisms of parasitism by what is the largest uncontrolled group of plant pathogens worldwide. The M. hapla genome encodes significantly fewer genes than does the free-living nematode Caenorhabditis elegans (most notably through a reduction of odorant receptors and other gene families), yet it has acquired horizontally from other kingdoms numerous genes suspected to be involved in adaptations to parasitism. In some cases, amplification and tandem duplication have occurred with genes suspected of being acquired horizontally and involved in parasitism of plants. Although M. hapla and C. elegans diverged >500 million years ago, many developmental and biochemical pathways, including those for dauer formation and RNAi, are conserved. Although overall genome organization is not conserved, there are areas of microsynteny that may suggest a primary biological function in nematodes for those genes in these areas. This sequence and map represent a wealth of biological information on both the nature of nematode parasitism of plants and its evolution.

Nasopharyngeal Carcinoma Ex Pleomorphic Adenoma: Case Report and Comprehensive Literature Review.

Carcinoma ex pleomorphic adenoma (CXPA) is an epithelial malignancy that transforms from benign pleomorphic adenomas (PA) at a rate of 1.5% after 5 years and 10% after 15 years. The average age of reported nasopharyngeal CXPA is 56.7 years. However, the present case describes a 19-year-old making this case exceptionally rare. Standard treatment is wide local excision with adjuvant treatment. We report the demographics, presentation, treatment, and outcomes of 8 cases of nasopharyngeal CXPA. While surgical excision is the mainstay of treatment, negative margins can be difficult to obtain at the skull base, and we report a recurrence rate of 50% in nasopharyngeal primaries. Due to the aggressive nature of the disease and high rate of recurrence, the majority of patients in our review received adjuvant radiation with some receiving adjuvant chemotherapy in addition.

Atypical Meningioma of the Sinonasal Tract.

This case report describes a patient with intellectual disability who presented with a neglected midline nasal mass eroding the anterior skull base, which was found to be a Grade II meningioma likely of the olfactory bulb. Points of interest include differential diagnosis of this atypical mass of the sinonasal tract, as well as decision-making in balancing appropriate management and quality of life in a patient with developmental delay who could not make decisions for herself. Literature review regarding the role of adjuvant radiation based on final diagnosis and extent of disease suggests that radiation can improve locoregional control and overall survival with atypical meningioma. Lack of clear information in the literature on these rare conditions can lead to poor understanding on the part of the treatment team and the healthcare proxies who are making decisions, making goals of care discussions and medical decision-making challenging. This case report seeks to add to the available data on management of atypical meningiomas of the sinonasal tract and olfactory bulb.

Postoperative Management After Tracheostomy and Laryngectomy: Improving Nursing Knowledge With Bedside Posters.

This study sought to improve nursing staff understanding regarding the differences in postoperative management between patients who have undergone tracheostomy and laryngectomy. The intervention involved a brief didactic session followed by the placement of an informative poster and anatomic diagram above the bed of tracheostomy and laryngectomy patients over a 6-month period. Data were collected before and after the didactic session and poster implementation. Of the 50 nurses surveyed, 32% believed oral ventilation is appropriate for laryngectomy patients compared to 0% of nurses after the intervention. The percentage of nursing staff reporting self-assessed clear understanding of the patient care differences between laryngectomy and tracheostomy improved after the intervention. The use of informational posters and didactic sessions significantly improves nursing staff understanding of the differences between tracheostomy and laryngectomy patients. Level of Evidence: IV.
