RESUMO

SUMMARY: Oncoplastic breast reconstruction seeks to address partial mastectomy defects in the setting of breast-conserving surgery to achieve superior aesthetic outcomes with comparable oncologic safety compared with traditional breast conservation surgery. As such, oncoplastic breast-conserving surgery has grown in popularity in recent years. Several techniques have been used to displace the volume with the remaining breast tissue or replace it with local soft-tissue options, with decision-making guided by patient and tumor characteristics, additional treatment requirements, patient preference, and available tissue resources. The purpose of this review is to provide an overview of considerations in oncoplastic breast reconstruction with a focus on techniques and tips to achieve optimal outcomes.

RESUMO

BACKGROUND: Prosthetic-based postmastectomy breast reconstruction in patients with large or pendulous breasts remains challenging because of inelastic and redundant skin, with various approaches to skin reduction at the time of mastectomy. This study describes the authors' experience with a Wise-pattern inferior dermal sling approach to skin-sparing mastectomy. METHODS: Retrospective chart review was performed on patients who underwent immediate prosthetic-based breast reconstruction after mastectomy from 2009 to 2021. A total of 240 patients who underwent Wise-pattern skin-sparing mastectomy (WSSM) were compared with a cohort of patients who had traditional elliptical skin-sparing mastectomy (ESSM), matched for mastectomy weight, prior radiation therapy, and smoking. Ninety-day postsurgical outcomes were examined. RESULTS: The WSSM cohort had a significantly higher body mass index (30.3 kg/m 2 versus 26.9 kg/m 2 ; P < 0.0001) and mastectomy weight (831 g versus 607 g; P < 0.0001). After propensity score matching, there was no significant difference in complication or treatment rates between WSSM and ESSM breasts except for mastectomy flap necrosis (11.6% versus 5.0%; P = 0.0082). WSSM patients who had mastectomy flap necrosis did not have significantly different treatment rates of admission, return to the operating room, or explantation compared with ESSM patients. CONCLUSIONS: In the largest reported series to date, WSSM was associated with a higher rate of mastectomy flap necrosis, but this did not translate into statistically significant differences in treatment. The inferior dermal flap likely acts as a protective layer of vascularized tissue, which appears to prevent evolution of mastectomy skin flap necrosis into more serious adverse outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

Hemoglobinopathies such as sickle cell disease (SCD) are traditionally considered a relative contraindication to free tissue transfer, due to concerns that erythrocyte sickling will increase the risk of microvascular thrombosis and flap failure. This article describes a case report with the successful use of free tissue transfer in a patient with SCD and provides a systematic literature review on free tissue transfer in SCD. A retrospective chart review was performed of a patient with SCD who underwent free tissue transfer at the authors' institution. A systematic literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed using the keywords "free tissue transfer," "free flap," or "microsurgery" and "sickle cell" on PubMed, Ovid/Medline, and Scopus. A 29-year-old male with delayed presentation of an electrical burn to the face and scalp underwent wound closure with a free anterolateral thigh flap. Key management principles included red blood cell transfusion to keep hemoglobin S under 30% and hemoglobin greater than 10 g/dL, maintenance of hydration, normothermia, adequate analgesia, and postoperative anticoagulation. Systematic literature review identified 7 articles describing 13 cases of free tissue transfer in 10 patients with SCD, with combined complete free flap success in 10 of the 13 flaps. Free tissue transfer can be successfully performed in patients with SCD. However, evidence on the optimal management of this unique patient population in the perioperative period after free tissue transfer is limited to case reports in the literature.

RESUMO

INTRODUCTION: Currently, there is limited literature on reconstructive trends for inpatient head and neck skin cancer. Rather, studies have focused primarily on patients treated on an outpatient basis. To gain a better understanding of the effect that reconstructive correction of complex skin cancer defects has on the healthcare system, we examined the existing incidence and reconstructive trends of head and neck melanoma and nonmelanoma skin cancer (NMSC) in the inpatient setting. METHOD: We performed the analysis of the Healthcare Cost and Utilization Project Nationwide Inpatient Sample Database (NIS) for the years 2012-2014 of the United States (US). Adults diagnosed with melanoma skin cancer or NMSC of the head and neck region were included. Patient characteristics, reconstructive modality, surgical specifics, and outcomes were retrieved. Trends with time for reconstruction techniques were analyzed. RESULTS: In total, 41,185 patients with a diagnosis of skin malignancy were identified, of whom 5,480 (13.3%) underwent reconstruction. Most patients were white (90.0%), male (71.6%), and had a diagnosis of NMSC (79.2%). An increase in flap reconstruction (p < 0.001) was observed. After population adjustment, the highest incidence of skin malignancy was found in the Northeast. CONCLUSION: There has been a trending increase in inpatient NMSC and melanoma skin cancer of the head and neck region, correlating to an increase in the reconstructive procedures performed, and greater cost burden. Resources may be allocated toward early identification and treatment for skin cancer to help control the current rise in complex skin cancer cases necessitating inpatient admission.

RESUMO

BACKGROUND: Brachial plexus injuries have devastating effects on upper extremity function, with significant pain, psychosocial stress, and reduced quality of life. The aim of this study is to identify socioeconomic disparities in the receipt of brachial plexus repair in the emergent versus elective setting, and in the use of supported services on discharge. METHODS: Analysis of the Healthcare Cost and Utilization Project National Inpatient Sample Database was performed for the years 2009-2014. Adults with brachial plexus injury with or without nerve repair were identified; patient and hospital specific factors were analyzed. RESULTS: Overall, 6,618 cases of emergent brachial plexus injury were retrieved. Six hundred sixty cases of brachial plexus repair were identified in the emergency and elective settings over the study period. Of the 6,618 injured, 153 (2.3%) underwent nerve surgery during the admission. Patients undergoing repair in the elective setting were more likely to be white males with private insurance. Patients treated in the emergency setting were more likely to be African American and in the lowest income quartile. Significant differences were also seen in supported discharge: more likely males (P < 0.001), >55 years of age (P < 0.001), white (P < 0.001), with government-based insurance (P < 0.001). CONCLUSIONS: There are significant disparities in the timing of brachial plexus surgery. These relate to timing rather than receipt of nerve repair; socioeconomically advantaged individuals with private insurance in the higher income quartiles are more likely to undergo surgery in the elective setting and have a supported discharge.

RESUMO

Goblet cell carcinoid (GCC) is a rare appendiceal tumor with unique morphologic features that shows glandular and neuroendocrine differentiation on immunohistochemistry. An additional component of adenocarcinoma (AC) can be present (GCC-AC). Both GCC and GCC-AC are staged and treated like AC. The histogenesis and genetic alterations underlying GCC and GCC-AC are unclear. Capture-based next-generation DNA sequencing targeting 479 cancer genes was performed on 19 appendiceal tumors: 4 GCC, 9 GCC-AC, 3 neuroendocrine tumors (NET), and 3 AC (2 conventional, 1 mucinous). Somatic coding mutations were not seen in any NET. Pathogenic (P)/likely pathogenic (LP) mutations were present in 1 GCC, 8 GCC-AC and all 3 AC cases. P/LP mutations in chromatin remodeling genes were seen in 4 (44.4%) GCC-AC cases, but not in NET, GCC or AC. In GCC-AC, P/LP mutations in ARID1A and RHOA were each present in 3 cases, and KDM6A and SOX9 mutations were each seen in 2 cases. APC and KRAS mutations were present in 1 conventional AC case, but were not observed in any GCC or GCC-AC. This limited series reveals mutations in SOX9, RHOA, and chromatin-modifier genes in goblet cell tumors, and shows that the mutational profile of GCC/GCC-AC is distinct from NET and conventional appendiceal AC.

RESUMO

Goblet cell carcinoid (GCC) is staged and treated as adenocarcinoma (AC) and not as neuroendocrine tumor (NET) or neuroendocrine carcinoma. The term carcinoid may lead to incorrect interpretation as NET. The aim of the study was to explore pitfalls in staging and clinical interpretation of GCC and mixed GCC-AC, and propose strategies to avoid common errors. Diagnostic terminology, staging, and clinical interpretation were evaluated in 58 cases (27 GCCs, 31 mixed GCC-ACs). Opinions were collected from 23 pathologists using a survey. Clinical notes were reviewed to assess the interpretation of pathology diagnoses by oncologists. NET staging was incorrectly used for 25% of GCCs and 5% of mixed GCC-ACs. In the survey, 43% of pathologists incorrectly indicated that NET staging is applicable to GCCs, and 43% incorrectly responded that Ki-67 proliferation index is necessary for GCC grading. Two cases each of GCC and mixed GCC-AC were incorrectly interpreted as neuroendocrine neoplasms by oncologists, and platinum-based therapy was considered for 2 GCC-AC cases because of the mistaken impression of neuroendocrine carcinoma created by use of the World Health Organization 2010 term mixed adenoneuroendocrine carcinoma. The term carcinoid in GCC and use of mixed adenoneuroendocrine carcinoma for mixed GCC-AC lead to errors in staging and treatment. We propose that goblet cell carcinoid should be changed to goblet cell carcinoma, whereas GCC with AC should be referred to as mixed GCC-AC with a comment about the proportion of each component and the histologic subtype of AC. This terminology will facilitate appropriate staging and clinical management, and avoid errors in interpretation.

RESUMO

BACKGROUND: Immediate reconstruction of perineal defects secondary to abdominoperineal resection (APR) or pelvic exenteration with pedicled flaps decreases postoperative wound complications when compared with direct closure in high-risk patients. Although some authors have been proponents of abdominal-based flaps, here we evaluate the role for thigh-based flaps founded on acceptable outcomes and low morbidity. STUDY DESIGN: Consecutive patients referred to a single surgeon between January 2012 and August 2015 who underwent perineal reconstruction with a pedicled gracilis flap were identified. Patients were evaluated for routine preoperative variables and outcomes data were analyzed, including time to healing and abdominal and perineal complications. RESULTS: Forty patients were included in the study, with a mean follow-up period of 2 years. There were no 30-day mortalities and 37 patients (92.5%) were alive at the last follow-up. Five patients (12.5%) experienced donor site complications and 16 patients (40%) had recipient site complications, including hematoma, seroma, or dehiscence. Minor complications were seen in 10 (25%) patients, and 7 (17.5%) patients had major complications. Obesity (odds ratio = 7.5; p = 0.01) and active smoking status (odds ratio = 9.3; p = 0.01) were significantly associated with minor complications, and a history of neoadjuvant chemoradiation (odds ratio = 21.4; p = 0.04) was a significant risk factor for any complication. CONCLUSIONS: The overall complication rate with this technique is comparable with the more commonly used vertical rectus abdominis myocutaneous flap, but the potential for, and severity of, donor site complications is reduced with this technique. As such, gracilis flaps can be considered an acceptable alternative to abdominal flaps for selected perineal wounds.

RESUMO

BACKGROUND: "Medical tourism" has gained popularity over the past few decades. This is particularly common with patients seeking elective cosmetic surgery in the developing world. However, the risk of severe and unusual infectious complications appears to be higher than for patients undergoing similar procedures in the United States. OBJECTIVES: The authors describe their experience with atypical mycobacterial infections in cosmetic surgical patients returning to the United States postoperatively. METHODS: A review of patient medical records presenting with infectious complications after cosmetic surgery between January 2010 and July 2015 was performed. Patients presenting with mycobacterial infections following cosmetic surgery were reviewed in detail. An extensive literature review was performed for rapid-growing mycobacteria (RGM) related to cosmetic procedures. RESULTS: Between January 2010 and July 2015, three patients presented to our institution with culture-proven Mycobacterium abscessus at the sites of recent cosmetic surgery. All had surgery performed in the developing world. The mean age of these patients was 36 years (range, 29-44 years). There was a delay of up to 16 weeks between the initial presentation and correct diagnosis. All patients were treated with surgical drainage and combination antibiotics with complete resolution. CONCLUSIONS: We present series of patients with mycobacterial infections after cosmetic surgery in the developing world. This may be related to the endemic nature of these bacteria and/or inadequate sterilization or sterile technique. Due to low domestic incidence of these infections, diagnosis may be difficult and/or delayed. Consulting physicians should have a low threshold to consider atypical etiologies in such scenarios. LEVEL OF EVIDENCE: 5 Therapeutic.

RESUMO

Frontotemporal lobar degeneration is a progressive neurodegenerative syndrome that is the second most common cause of early-onset dementia. Mutations in the progranulin gene are a major cause of familial frontotemporal lobar degeneration [Baker M, et al. (2006) Nature 442:916-919 and Cruts M, et al. (2006) Nature 442:920-924]. Although progranulin is involved in wound healing, inflammation, and tumor growth, its role in the nervous system and the mechanism by which insufficient levels result in neurodegeneration are poorly understood [Eriksen and Mackenzie (2008) J Neurochem 104:287-297]. We have characterized the normal function of progranulin in the nematode Caenorhabditis elegans. We found that mutants lacking pgrn-1 appear grossly normal, but exhibit fewer apoptotic cell corpses during development. This reduction in corpse number is not caused by reduced apoptosis, but instead by more rapid clearance of dying cells. Likewise, we found that macrophages cultured from progranulin KO mice displayed enhanced rates of apoptotic-cell phagocytosis. Although most neurodegenerative diseases are thought to be caused by the toxic effects of aggregated proteins, our findings suggest that susceptibility to neurodegeneration may be increased by a change in the kinetics of programmed cell death. We propose that cells that might otherwise recover from damage or injury are destroyed in progranulin mutants, which in turn facilitates disease progression.
