Squamous cell carcinoma of the colon: evaluation of treatment modalities and survival.

BACKGROUND: Squamous cell carcinoma of the colon (CSCC) is a rare subtype of colon cancer. This study aimed to evaluate treatment strategies and overall survival (OS). METHODS: Using the Surveillance, Epidemiology, and End Results program database from 2008 to 2019, patients aged 18 years with CSCC were identified. Treatment strategies and OS were summarized using the Kaplan-Meier analysis and the log-rank test. Adjusted Cox proportional hazards regression model ratios were calculated to evaluate the effect of confounding variables. RESULTS: After exclusions, 153 patients met the inclusion criteria. The most common treatment modalities included surgery alone (52.1%), surgery and adjuvant chemotherapy (12.9%), and no treatment (26.4%). Kaplan-Meier analysis revealed that patients who underwent surgery and adjuvant chemotherapy had significant improvements in OS (log-rank P = .002). Cox regression analysis revealed tumor grade (hazard ratio [HR], 2.12; 95% CI, 1.17-3.86) and receipt of chemotherapy (HR, 2.66; 95% CI, 1.23-5.76) as the only factors associated with improvements in OS. CONCLUSION: Patients who underwent surgery in combination with chemotherapy had better OS than those who underwent surgery alone. Tumor grade and receipt of chemotherapy were independently associated with OS.

Development of a Scoring Rubric Assessing Medical Students' Explanations of Pathology Reports.

CONTEXT.­: With increasing availability of immediate patient access to pathology reports, it is imperative that all physicians be equipped to discuss pathology reports with their patients. No validated measures exist to assess how pathology report findings are communicated during patient encounters. OBJECTIVE.­: To pilot a scoring rubric evaluating medical students' communication of pathology reports to standardized patients. DESIGN.­: The rubric was iteratively developed using the Pathology Competencies for Medical Education and Accreditation Council for Graduate Medical Education pathology residency milestones. After a brief training, third- and fourth-year medical students completed 2 standardized patient encounters, presenting simulated benign and malignant pathology reports. Encounters were video recorded and scored by 2 pathologists to calculate overall and item-specific interrater reliability. RESULTS.­: All students recognized the need for pathology report teaching, which was lacking in their medical curriculum. Interrater agreement was high for malignant report scores (intraclass correlation coefficient, 0.65) but negligible for benign reports (intraclass correlation coefficient, 0). On malignant reports, most items demonstrated good interrater agreement, except for discussing the block (cassette) summary, explaining the purpose of the pathology report, and acknowledging uncertainty. Participating students (N = 9) felt the training was valuable given their limited prior exposure to pathology reports. CONCLUSIONS.­: This pilot study demonstrates the feasibility of using a structured rubric to assess the communication of pathology reports to patients. Our findings also provide a scalable example of training on pathology report communication, which can be incorporated in the undergraduate medical curriculum to equip more physicians to facilitate patients' understanding of their pathology reports.

Radioligand Therapy (RLT) in the form of [177Lu] Lu-DOTA-TATE (Lutathera®) is a promising treatment for pancreatic neuroendocrine tumors (pNETs) with cardiac metastasis. We present a patient treated with [177Lu] Lu-DOTA-TATE that showed shrinkage of metastasis after four treatments at 7.4 GBq every 8 weeks.

Malignant mixed mullerian tumors: a SEER database review of rurality and treatment modalities on disease outcome.

Introduction: Malignant Mixed Mullerian Tumors (MMMT) are rare and poorly understood sarcomas with limited research on risk factors, pathogenesis, and optimal treatments. This study aimed to address this knowledge gap and explore the impact of community size, patient characteristics, disease characteristics, and treatment modalities on MMMT outcomes. Methods: Using the Surveillance, Epidemiology, and End Results database (SEER), the largest SEER cohort to date of 3,352 MMMT patients was analyzed for demographic factors, treatment modalities, and histologic characteristics. Data was processed, including the removal of incomplete entries, and analyzed in Python 3.1 using packages scikit-learn, lifelines, and torch; log-rank analysis and Cox proportional hazards models were used to evaluate a number of demographic characteristics and disease characteristics for significance in regard to survival. Results: Our study found adjuvant radiotherapy and chemotherapy significantly improved survival, with modest benefits from neoadjuvant chemotherapy. Our findings also suggest age at diagnosis, disease grade, and suburban versus rural geographic locations may play key roles in patient prognosis. On multivariable analysis both disease Grade and surgical treatment were significant factors. Discussion: MMMTs remain challenging, but appropriate treatment appears to enhance survival. The present findings suggest opportunities for improved outcomes and treatment strategies for patients with MMMTs.

Squamous cell carcinoma of the bladder: Demographics and outcomes associated with surgery and radiotherapy.

BACKGROUND AND OBJECTIVES: Squamous cell carcinoma of the bladder (SCCB) is a rare disease composing 2%-5% of all bladder cancers with no consensus regarding treatment. The present study aims to analyze the outcomes of established treatments, namely chemotherapy, radiation, and surgery, to guide clinical decision-making for patients with non-schistosomal SCCB. METHODS: Patients with bladder SCC diagnosed between 2000 and 2018 were reviewed utilizing data from the Surveillance, Epidemiology, and End Results Registry (SEER) program. RESULTS: A total of 5653 patients with SCCB were identified; median survival was 13 months and was significantly decreased in patients treated with chemotherapy or radiation (median survival of 9 or 12 months, respectively). Patients treated with both surgery and radiotherapy saw a decreased 5 year overall survival (OS) of 14%, compared to 35% for those treated with surgery alone (p < 0.01). Furthermore, patients treated with surgery, chemotherapy, and radiotherapy saw a decreased 5 year OS of 20%, compared with 25% for those that received surgery and chemotherapy only (p < 0.01). Finally, surgical intervention provided an increased 5 year OS for patients with locoregional disease only; those with distant disease saw no increase in 5 year OS (p < 0.01). CONCLUSIONS: Based on this study's analysis, radical surgery may be the most effective treatment for this disease.

Emergent bedside management of a pneumatocele in a neonate via Fogarty catheter.

Persistent pneumatoceles in neonates increase mortality, and little literature regarding emergent treatment in a decompensating patient exists. We present the emergent management of a pneumatocele in a decompensating neonate by isolation with a Fogarty catheter.

Surgical management of a type A aortic dissection in a pregnant patient.

Despite emphasis for emergent surgical treatment of Stanford type A aortic dissections, pregnant patients that are clinically stable may safely receive a staged approach instead, with delivery followed by delayed dissection repair.

Knowledge Retention From Emergency Medicine Simulation-Based Learning Curriculum for Pre-clinical Medical Students.

Introduction Traditional medical school curricula rely on textbook-based learning during the first two years, often limiting students' clinical exposure. Simulation-based learning (SBL) provides an opportunity for students to gain clinical exposure and competency with common procedures as well as to gain knowledge related to common clinical topics. Retention of factual knowledge is a current topic of discussion as medical learners often have difficulty with long-term retention. The aim of this study was to assess if students would learn, retain, and enjoy emergency medicine (EM)-focused SBL. Materials and methods We developed an EM-focused SBL curriculum consisting of four main educational events: suturing, medical stabilization, mass casualty triage, and point-of-care ultrasound (POCUS). Participants were first- and second-year healthcare students enrolled in a traditional, preclinical curriculum, who completed pre- and post-event quizzes consisting of multiple-choice questions on topics covered during the SBL scenario. We compared pre- and post-event quiz scores using a one-way paired t-test. Quizzes were readministered up to 100 days after each SBL event to test knowledge retention, and scores were compared across time by repeated-measures analysis of variance (RMANOVA). Results For suture (n=22), mass casualty (n=20), and ultrasound simulations (n=17), post-event mean quiz scores increased significantly in comparison to mean quiz scores from before the event (p≤0.05). Medical stabilization simulation post-event scores were increased but did not reach statistical significance. Data collected at 45, 74, and 94 days following the suture lab as well as 29 and 49 days after the medical evacuation event, and 20 days after the mass casualty event showed no statistical decrease in quiz means suggesting retention of knowledge among learners. Subjective assessments of participant satisfaction demonstrated an enjoyment of the events. Discussion EM-focused SBL events offered enjoyable learning opportunities for students to effectively obtain and possibly retain clinical knowledge. Conclusion SBL has the potential to improve student retention of clinical knowledge during the preclinical years and, therefore, should be further explored and implemented as a core pillar of medical education as opposed to its current state as a learning adjunct.

Airway management and quadratus lumborum block for inguinal hernia repair in context of chromosome 4q deletion: A case report.

Key Clinical Message: Chromosome 4q Deletion Syndrome (4QDS) is a rare chromosomal deletion that presents with various congenital defects that could affect anesthetic management. We present a patient with known 4QDS who underwent successful general anesthetic induction, tracheal intubation, and subsequently, bilateral quadratus lumborum nerve blocks, during laparoscopic inguinal hernia repair surgery. Abstract: Chromosome 4q deletion syndrome (4QDS) is a rare chromosomal deletion with the potential for congenital defects that could affect the anesthetic management of affected patients, specifically with inconsistent reports of possible laryngeal narrowing which could precipitate intubation difficulties. We present a report of a patient with known 4QDS who underwent successful general anesthetic induction and tracheal intubation, followed by subsequent bilateral quadratus lumborum nerve blocks, in the context of laparoscopic inguinal hernia repair surgery. Given the inconsistent presentation of patients with 4QDS reported in the literature, steps were taken to exercise sufficient caution concerning the overall management of this patient per the most recent guidelines for pediatric patients.

Bacterial epiglottitis superimposed on oropharyngeal cancer: A case report.

BACKGROUND: Patients undergoing chemotherapy and radiotherapy are placed in an immunocompromised state worth consideration in the event of potential airway compromise, especially when superimposed on an airway-obstructing tumor. We report a case of bacterial epiglottitis in a patient with active oropharyngeal cancer (OPC), who presented in such a way that an infectious etiology was not initially considered in the patient's care. To our knowledge, such a circumstance has not been reported in the literature. CASE: Here, we report a case of a 68-year-old male with advanced-stage OPC who developed respiratory distress and underwent emergent tracheostomy. The patient was diagnosed postoperatively with Haemophilus influenza and Pseudomonas aerugeniosa. Following antibiotic treatment, the patient recovered to the point in which he could then undergo concomitant chemoradiation. The patient later had a recurrence of P. aerugeniosa during their radiotherapy that was also treated with antibiotics. The patient experienced continued symptoms related to their OPC and underwent pharyngectomy. Despite the initial success of this procedure, the patient experienced tumor recurrence and succumbed to his disease. CONCLUSION: This case underscores the importance of considering multiple etiologies concerning airway compromise, as the consequence of delayed cancer treatment may be loss of local cancer control.

Radiation-induced myofibroblastoma within the nasal sinus requiring maxillectomy and ethmoidectomy: A case report and literature review.

We report a case of radiation-induced myofibroblastoma of the right nasal cavity in a patient with a remote history of radiotherapy for pediatric retinoblastoma. The patient required maxillectomy and ethmoidectomy. To our knowledge, a rare number of cases have been reported in this location.

Outcomes of farm compared to nonfarm pediatric injuries: A propensity-matched analysis.

OBJECTIVES: Pediatric farm-related injuries are rare but tend to be severe relative to other types of pediatric injury and may result in worse clinical outcomes. However, the comparison of farm and nonfarm injuries is confounded by different injury mechanisms, patient characteristics, and treating facilities. Therefore, we used propensity score matching to compare outcomes of pediatric farm and nonfarm injuries in the United States. METHODS: Data were obtained from the 2017-2019 Trauma Quality Program database. Farm as compared to nonfarm injury was defined as the location of an injury and served as the independent variable analyzed in this study. The outcome variables analyzed were in-hospital mortality, hospital length of stay (LOS), and admission to the intensive care unit (ICU). RESULTS: We identified 2,040 farm injuries and 201,865 nonfarm injuries meeting inclusion criteria. In this cohort, the mortality rate was 1%, median LOS was 2 days, and 14% of patients were admitted to the ICU. In the propensity-matched analysis (including 2,039 farm cases matched to 2,039 nonfarm controls), farm as compared to nonfarm injuries were associated with 5% longer LOS (95% CI: 1%, 8%; P = .01), but not mortality or ICU admission. CONCLUSIONS: In a propensity-matched analysis, pediatric farm injuries resulted in prolonged hospital stay compared to nonfarm injuries. Identifying patient- and health care system-level factors contributing to prolonged LOS may help optimize the care of children injured on farms.

Health care utilization in a nurse practitioner-led atrial fibrillation clinic.

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is emerging in prevalence with an increasingly aging population. The complex nature of the disease and its association with significant morbidity and mortality has resulted in a call for a new integrative, multidisciplinary approach to AF management. PURPOSE: Determine if the use of a nurse practitioner (NP)-led AF clinic (NPAFC) can improve care for patients. METHODOLOGY: An NPAFC was designed to serve as an independent clinic for standardizing patient care and improving access to care. Baseline patient demographics, care pathway, and interventions were characterized in clinic. Primary outcomes were hospitalizations and emergency department (ER) visits, before and after clinic implementation. RESULTS: Overall, 1,442 patients were enrolled in the AF clinic between January 2016 and June 2018. The mean age at the first AF clinic visit was 68.7 ± 12.6 years, 54% were male, and the mean body mass index was 31 ± 7 kg/m2. Among the patients, 45.2% had paroxysmal AF, 43.6% persistent AF, and 5.5% permanent AF. With an average of 3 ± 3 clinic visits per patient, the number of patients with ≥1 hospitalization decreased by 78% after clinic implementation. Similarly, the number of patients with ≥1 ER visit decreased by 79%, and 22.7% of patients avoided at least one ER visit. CONCLUSIONS: The number of patients with ≥1 hospitalization or ≥1ER visit decreased within two years after the implementation of an NPAFC. IMPLICATIONS: Implementation of an NP-led AF clinic in the United States may reduce hospitalizations and ER visits if implemented in an integrative model.

The impact of curated educational videos on pathology health literacy for patients with a pancreatic, colorectal, or prostate cancer diagnosis.

Despite patients having increased access to their own electronic health record (EHR) in recent times, patients are often still not considered a primary audience of pathology reports. An alternative to in-person patient education is the use of multimedia programming to enhance health literacy. Curated video presentations designed to explain diagnosis-specific pathology terms were reviewed by a board-certified pathologist and oncologist team and then shown to patients with a primary diagnosis of either pancreatic, colorectal, or prostate cancer in-clinic; these patients then completed a secure electronic survey immediately afterwards. Seventy patients were surveyed, with 91% agreeing or strongly agreeing that the video they watched increased their understanding of the medical terms used in their pathology reports, with a corresponding average Likert score (ALS) of 4.21 (SD = 0.77, CI = ± 0.18). Furthermore, 95% agreed or strongly agreed that the video they watched both enhanced their understanding of the role of the pathologist in diagnosing cancer (ALS = 4.27; SD = 0.65, CI = ± 0.15) and reported they found the video useful (ALS = 4.27; SD = 0.53, CI = ± 0.13). Curated videos such as those utilized in this study have the potential to increase patient health literacy and inform patients of the multidisciplinary nature of cancer diagnosis.

The Impact of Smoking, Alcohol Use, Recurrent Disease, and Age on the Development of Neck Fibrosis in Head and Neck Cancer Patients Following Radiation Therapy.

There is a paucity of information regarding the demographic factors associated with the development of neck fibrosis in head and neck cancer (HNC) patients following radiotherapy. A retrospective review of all patients being treated for HNC at a tertiary care center between 2013 and 2017 was performed. Chi-squared and Mann-Whitney U tests were used to identify differences in incidence and grade of fibrosis, respectively, between populations. A total of 90 patients aged 19 to 99 years were included. Factors associated with an increased incidence of fibrosis included smoking during radiotherapy (p < 0.001), alcohol use (p = 0.026), recurrent disease (p = 0.042), and age less than 60 (p < 0.001) on univariate analysis. Factors associated with increased grade of fibrosis in HNC patients included recurrent HNC (p = 0.033), alcohol use (p = 0.013), patient age younger than 60 years (p = 0.018), smoking during radiotherapy (p < 0.001), and non-Caucasian race (p = 0.012). Identification and intervention directed at patients that possess risk factors associated with fibrosis prior to treatment has the potential to improve the long-term quality of life for HNC patients.
