RESUMO

Inflammatory breast cancer (IBC) is a rare yet aggressive form of invasive ductal carcinoma, with a poor prognosis and decreased 5-year survival rates. Characteristic findings for IBC include rapid onset of breast edema, peau d'orange appearance, and involvement of the breast skin. Additionally, diagnosis is confirmed with a skin punch biopsy. With such nonspecific features, IBC can be mistaken for benign etiologies, causing delays in diagnosis and treatment. This patient is a 44-year-old woman presenting with left breast swelling while concurrently breastfeeding. Following antibiotic treatment but no symptom resolution, the patient was referred out for further follow-up. Despite multiple imaging studies, suggesting benign findings, clinical suspicion prompted continued evaluation and finally diagnosis of triple-negative inflammatory breast cancer with distant metastases. Further awareness of the presentation of IBC and its mimicking of other disease processes such as mastitis is paramount to earlier detection and improved outcomes in future patients.

RESUMO

BACKGROUND: Musculoskeletal discomfort is widely experienced by surgeons across multiple surgical specialties. Developing technologies and new minimally invasive techniques add further complexity and ergonomic stressors. These stressors differentially affect male and female surgeons, but little is known about the role these sex disparities play in surgical ergonomic stress. We reviewed existing literature to better understand how ergonomic stress varies between male and female surgeons. STUDY DESIGN: A literature search was performed via PubMed including but not limited to the following topics: ergonomics, surgeons, female surgeons, women surgeons, pregnancy, and operating room. A review of available quantitative data was performed. RESULTS: Female surgeons endure more pronounced ergonomic discomfort than their male counterparts, with added ergonomic stress associated with pregnancy. CONCLUSIONS: A 4-fold method is proposed to overcome ergonomic barriers, including (1) improved education on prevention and treatment of ergonomic injury for active surgeons and trainees, (2) increased departmental and institutional support for ergonomic solutions for surgeons, (3) partnerships with industry to study innovative ergonomic solutions, and (4) additional research on the nature of surgical ergonomic challenges and the differential effects of surgical ergonomics on female surgeons.

RESUMO

Epigenetic alterations are a key hallmark of aging but have been limitedly explored in tissues. Here, using naturally aged murine liver as a model and extending to other quiescent tissues, we find that aging is driven by temporal chromatin alterations that promote a refractory cellular state and compromise cellular identity. Using an integrated multi-omics approach and the first direct visualization of aged chromatin, we find that globally, old cells show H3K27me3-driven broad heterochromatinization and transcriptional suppression. At the local level, site-specific loss of H3K27me3 over promoters of genes encoding developmental transcription factors leads to expression of otherwise non-hepatocyte markers. Interestingly, liver regeneration reverses H3K27me3 patterns and rejuvenates multiple molecular and physiological aspects of the aged liver.

RESUMO

The importance of resident wellbeing is increasingly recognized by the ACGME as essential. While prior studies have quantified wellbeing/burnout, few have defined wellbeing from the resident-physician perspective. A REDCap® survey was distributed to residents in various programs, responses were grouped by theme, and data analyzed via chi-square. From 19 institutions, 53/670 responded, from university (34.0%), community (30.2%), and community/university-affiliated (30.2%) programs, mostly surgical (84.9%), followed by medical (9.4%). Wellbeing was defined by mental and spiritual/religious health (33.8%), overall health (23.0%), free time/time management (23.0%), and job/salary satisfaction (18.9%). Proposed changes to traditional training included fewer hours and more schedule flexibility (38.2%), and increased/improved support/feedback (14.7%). Nearly half of the respondents perceived lacking education on career longevity. Wellbeing is paramount to the personal/professional development of residents. Data on resident-defined wellbeing are lacking. The improved understanding of wellbeing defined here can be used to improve residency training programs.

RESUMO

Immunoglobulin light chain (AL) amyloidosis is a rare disease characterized by the deposition of misfolded extracellular proteins within various body tissues resulting in dysfunction of the cardiac, renal, gastrointestinal, hematologic, and nervous systems, among others. Systemic AL amyloidosis often presents with a constellation of vague symptoms such as fatigue, dyspnea, and abdominal pain. Untreated AL amyloidosis with cardiac involvement is rapidly fatal with a median survival of 6 months. In this report, we will highlight the case of a 43-year-old female who presented with generalized abdominal symptoms and fatigue. She was found to have extensive inferior vena cava (IVC) thrombosis extending into the renal veins bilaterally in the setting of nephrotic range proteinuria, new onset arrhythmia, diastolic heart failure, gastrointestinal, and autonomic dysfunction. She received systemic thrombolytic therapy for the IVC and renal vein thrombosis. The multiorgan involvement led us to consider the possibility of amyloidosis. Abdominal fat pad biopsy was performed as part of the diagnostic effort. The abdominal fat pad biopsy did not reveal AL amyloidosis. Ultimately, the diagnosis of systemic AL amyloidosis was made on the basis of pathology from luminal biopsies obtained during outpatient esophagogastroduodenoscopy that was performed days prior to her admission. Unique to our case is the patient presentation with extensive thrombotic disease of the IVC and renal veins. It is important to understand the disease process, presenting signs and symptoms as well as diagnostic essentials based on current literature in order to minimize the morbidity and mortality of this rare disease.

RESUMO

BACKGROUND: Lactate levels in clinical practice are often used as a quantitative indicator for the severity of hypoperfusion and the responsiveness to therapeutic interventions. In the hospital acute care setting, lactic acidosis combined with the appropriate clinical exam signs warrants surgical evaluation. The purpose of our study was to evaluate all surgical consults for lactic acidosis in a single community hospital to identify what cofactors were most often predictive of the need for surgical management and operative intervention. MATERIALS AND METHODS: A retrospective chart review within a 5-year period was conducted on all consultations to general surgery in which patients additionally had lactic acidosis defined as >2mEq. Within this population, various subjective and objective parameters were evaluated. Final analysis compared these parameters between patients with lactic acidosis who underwent surgical intervention and those who did not require operative intervention. RESULTS: Within the 5-year period, 432 patients met our criteria of a surgical consult placed for lactic acidosis. Final results from the highest quality statistical model showed significant variables as diffuse tenderness on physical exam (P-value = .0010, Odds Ratio (OR) = 2.77) and focal tenderness on physical exam (P-value = .0440, OR = 1.76). The presence of peritoneal signs (P-value = .0521, OR = 2.02) resulted in operative intervention twice as often in patients with lactic acidosis. DISCUSSION: To better appropriate health care costs, measures need to be taken to ensure resources are being utilized properly. In patients with lactic acidosis, one should go "back to the basics" with the physical examination to determine which patients truly need a surgical consultation.

RESUMO

BACKGROUND: The morbidity and mortality rates associated with cholecystectomy for acute cholecystitis are higher in the critically ill elderly population. As an alternative to cholecystectomy, we report the results of treatment of acute cholecystitis in the elderly after open cholecystolithotomy with cholecystostomy tube placement under local anesthesia. METHODS: A case series was performed on 5 patients from August 2007 to April 2010 who presented with acute cholecystitis and underwent an open cholecystolithotomy and tube placement. Thirty-day mortality, intra- and immediate-postoperative complications, clinical improvement after drainage, additional biliary procedures needed, and outcome after cholecystostomy tube removal were recorded. RESULTS: Open cholecystolithotomy and tube placement were performed successfully in all patients and permitted resolution of the acute attack in all after a mean period of 3.75 days. Thirty-day mortality was 0%. Patients did not experience any intraoperative complications. We observed 100% rate of successful short-term outcomes in our patients including resolution pain, and objectively, normalization of leukocytosis, and defervescence. None of the patients required emergency cholecystectomy. All patients had their cholecystostomy tubes removed at a mean postoperative day 27. There were no cases of biliary leakage or tube dislodgement. There were no recurrences of acute cholecystitis within the mean follow-up of 20.75 months. DISCUSSION: Emergency open cholecystolithotomy and cholecystostomy tube placement represent an effective, safe, and definitive alternative treatment strategy for acute gallstone cholecystitis in selected elderly patients with a mortality rate of 0% in the authors' experience.

RESUMO

While liposarcoma is one of the most common soft tissue sarcomas, it is rarely seen within the gastrointestinal tract, and even less frequently seen within the colon. Dedifferentiated liposarcoma is a subtype of liposarcoma, which along with the pleomorphic subtype is considered a high-grade, aggressive tumor; both possess the ability to metastasize and are associated with decreased survival. Despite complete resection, recurrence is common. While surgical excision is the cornerstone of treatment for liposarcoma of the colon, there is no consensus on adjuvant therapies. We present the case of a 66-year-old woman who presented with abdominal pain with rectal bleeding and was found on colonoscopy to have a high-grade dedifferentiated liposarcoma of the transverse colon. She underwent robotic segmental colectomy. Due to absence of nodal involvement or distal metastasis, adjuvant therapy was not administered. On 1-year follow-up, the patient remains disease free.

RESUMO

Raoultella ornithinolytica is a Gram-negative rod belonging to the Enterobacteriaceae family and closely related to Klebsiella spp. It is commonly present in aquatic environments. Human infections caused by R. ornithinolytica are being increasingly recognized. It has been documented to cause various hospital-acquired infections including but not limited to gastrointestinal, skin, and genitourinary infections. The organism has been particularly associated with invasive procedures and is commonly seen in patients with malignancy, diabetes, chronic kidney disease and immunodeficiency. To our knowledge, we report the first case of pyogenic liver abscess caused by this organism. The patient presented subtly with a chronic, nonresolving cough and was managed successfully by surgical drainage and appropriate antimicrobials.

RESUMO

BACKGROUND: General surgery residents log operative case experience as "first assist" (FA) or "primary surgeon" (PS). This study will evaluate their quantitative and qualitative case log practices. METHODS: Modified Delphi technique was used to create a questionnaire and distributed online to institutions via the APDS. Descriptive analyses and example operative scenarios for resident case logging habits were ascertained. RESULTS: There were 363 residents from university (60%) and non-university (40%) programs; 94% did not know the definition of primary surgeon. Over 50% stated they had been encouraged to log a case as surgeon that they did not feel was warranted. Only 4% felt the current logging system is "very accurate." Given an operative scenario, residents varied how they chose to log the case. CONCLUSION: General surgery residents do not know the current definition of PS. Case logging should be an objective measure of resident operative exposure, but may actually be more complex than previously recognized.

RESUMO

BACKGROUND: The field of telemedicine has grown tremendously over the last decade. We present a systematic review of publications on telemedicine as it pertains to surgery, addressing six facets: 1) telerobotics, 2) telementoring, 3) teleconsulting, 4) telemedicine in post-operative follow-up, 5) tele-education, and 6) current technology. DATA SOURCES: A search of relevant literature querying PubMed, Web of Science, and Science Direct was performed using the following keywords: telecommunication, telemedicine, telehealth, virtual health, virtual medicine, general surgery, surgery, surgical or surgical patients. CONCLUSIONS: Telemedicine is being used to care for patients in remote areas, to help expert surgeons assist other specialists in the office or novice surgeons in the operating room, as well as to help teach the next generation of surgeons. There are many opportunities for surgeons to utilize this technology to optimize their practice.

RESUMO

BACKGROUND: Climate change will affect most populations in the next decades and put the health of billions of people at risk. Health care facilities represent a significant source of pollution around the world and contribute to environmental changes. To address this topic, we performed a review of the available literature on tactics to reduce operating room (OR) waste and the potential of these strategies to impact the environment. DATA SOURCES: A literature search was performed querying PubMed, Web of Science, and Science Direct. No comparative data were found; most were opinion papers, white papers, and case studies. For this reason, we proceeded with a narrative review, which provides an overview of the evidence on this topic and identifies areas for future research. RESULTS: This systematic review summarizes the available literature on the 5 "Rs" of waste management: reduction, reusing, recycling, rethinking, and renewable energies. CONCLUSIONS: Surgery has a unique opportunity to transition to more environmentally-friendly operating room strategies, which may help decrease waste and lessen the impact of climate change.

RESUMO

INTRODUCTION: It has been estimated that the probability of a physician being involved in a medical litigation by 65 years of age ranges from 76 to 98% depending on specialty. We hypothesized that a mock deposition held by a medico-legal expert attorney could effectively increase awareness of the importance of accurate and complete medical documentation. METHODS: Pre and post-lecture and mock deposition surveys were analyzed and the contents evaluated. Residents and attendings from the surgical, medical and OB-GYN departments participated. Results were analyzed through frequency distribution. RESULTS: A total of 62 participants attended, 42 completed the pre-survey, while 24 completed the post-survey. Majority had no prior experience in malpractice lawsuits. After the post-survey, 95.8% believed that incorporating the mock deposition may reduce documentation error. CONCLUSION: Based on the results of the surveys we concluded that a mock deposition exercise provides a means for education residents regarding the importance of medical documentation.

RESUMO

CONTEXT: Gallstone disease is a major health problem addressed by general surgeons, with approximate incidence of 10-15% in the Western world. With increasing focus in the healthcare literature on cost containment, controlling excess lengths of hospital stay (LOS) in this population is paramount. The aim of this study was to determine the factors that influence LOS in cholecystectomy patients to examine whether results would indicate a possible improvement in perioperative patient care and decrease costs at our community hospital in a suburban setting. METHODS: This is a retrospective review during a two-year period from 1/1/2013-12/31/2014 of patients admitted from the emergency department and undergoing cholecystectomy during the same admission. The study team analyst conducted univariate analysis for significant predictors of length of stay. RESULTS: The authors identified a total analytic sample of 312 subjects who met inclusion criteria. Sample patients admitted to the surgical service had a statistically significant shorter LOS than those patients who were not (3.4 days +/- 1.7 vs 5.6 days +/- 3.0; p value <0.0005). There was also a moderate positive correlation between decreased time to surgery and LOS (Pearson R-value 0.420, p value < 0.0005). Patients admitted to non-surgical services were more likely to have comorbidities like COPD, DM, arrhythmia, CAD, anticoagulation, CHF and previous abdominal surgeries. However, when placing each comorbidity into an analysis of covariance, patients admitted to surgical services still had a significantly shorter LOS (p value < 0.0005). CONCLUSIONS: Admission to a non-surgical service and increased length of time to surgical intervention were associated with prolonged LOS and potentially increased cost in cholecystectomy patients in this study sample. Though patients admitted to non-surgical services are "sicker," they still had prolonged LOS when controlling for comorbidities. Based on these findings, the establishment of an acute care surgery service may help to address this disparity in care.
