A Review of the Use of Topical Calendula in the Prevention and Treatment of Radiotherapy-Induced Skin Reactions
Calendula is a topical agent derived from a plant of the marigold family Calendula Officinalis. Containing numerous polyphenolic antioxidants, calendula has been studied in both the laboratory and clinical setting for the use in treating and preventing radiation induced skin toxicity. Despite strong evidence in the laboratory supporting calendula’s mechanism of action in preventing radiation induced skin toxicity, clinical studies have demonstrated mixed results. In light of the controversy surrounding the efficacy of calendula in treating and preventing radiodermatitis, the topic warrants further discussion

Lipoma and liposarcoma of the larynx: case reports and literature review
Two cases of laryngeal lipomatous tumors are presented. Their diagnoses and management are discussed and contrasted.
Case report and literature review.
Patient 1 is a 58 year old male presenting with five years of progressive shortness of breath, dysphagia, and globus sensation. Clinical exam and imaging study showed a 3.5 cm hypodense laryngeal mass, and he underwent transoral robotic-assisted surgery for complete excision. Final pathology revealed a well-differentiated liposarcoma. Patient 2 is a 79 year old female presenting with one year of non-progressive hoarseness and globus sensation. Clinical examination and imaging study revealed a 1.8 cm hypodense laryngeal mass. Transoral endoscopic complete excision of the submucosal mass was performed. Final pathology revealed benign spindle-cell lipoma.
Liposarcoma and lipoma may present with similar symptomatology, clinical, and imaging findings. Pathology evaluation is of utmost importance for definitive diagnosis. Therefore, diagnosis and treatment of laryngeal lipomatous lesions are best accomplished with complete excision of the mass
Role of innate immunity in the pathogenesis of otitis media
Otitis media (OM) is a public health problem in both developed and developing countries. It is the leading cause of hearing loss and represents a significant healthcare burden. In some cases, acute OM progresses to chronic suppurative OM (CSOM), characterized by effusion and discharge, despite antimicrobial therapy. The emergence of antibiotic resistance and potential ototoxicity of antibiotics has created an urgent need to design non-conventional therapeutic strategies against OM based on modern insights into its pathophysiology. In this article, we review the role of innate immunity as it pertains to OM and discuss recent advances in understanding the role of innate immune cells in protecting the middle ear. We also discuss the mechanisms utilized by pathogens to subvert innate immunity and thereby overcome defensive responses. A better knowledge about bacterial virulence and host resistance promises to reveal novel targets to design effective treatment strategies against OM. The identification and characterization of small natural compounds that can boost innate immunity may provide new avenues for the treatment of OM. There is also a need to design novel methods for targeted delivery of these compounds into the middle ear, allowing higher therapeutic doses and minimizing systemic side effects

Factors impacting contemporary management of high-grade extremity sarcoma: An analysis of 12,020 patients
11017 Background: Previous studies noted racial/ethnic disparities in high-grade extremity soft tissue sarcoma (ESS) treatment and overall survival (OS). Retrospective series have noted worse OS for Amputation (Amp) vs limb salvage surgery (LSS) and for LSS alone vs LSS plus radiation (RT). Given superior functional outcomes, LSS is now favored over Amp when possible. This study examines racial/ethnic disparities in receipt of Amp vs LSS and impact on OS using modern data from a national registry. Methods: The National Cancer Database was used to identify patients (pts) with stage II-III, high-grade ESS diagnosed between 2004-2014 and treated definitively with 1) Amp alone, 2) LSS alone, 3) Preoperative RT [pre RT] + LSS or 4) LSS + Post-operative RT [post RT]. Multivariate analyses (MVA) utilized logistic regressions for patterns of local treatment and Cox proportional hazards regression for OS. The Kaplan-Meier method was used to estimate 5-year OS. Results: Among 12,020 pts, receipt of LSS vs Amp did not differ significantly by race, ethnicity, age, insurance status, income, or educational attainment on MVA. The rate of Amp was higher in academic centers (OR 2.42; p = .006) or integrated network programs (OR 2.30; p = .014) vs community programs and rural vs. Metro settings (OR 1.88; p = .035). Actuarial 5-year OS by treatment was Amp 43%, LSS 59%, pre RT + LSS 61%, and LSS + post RT 66% (p < .001). On MVA, OS was worse with Amp vs. LSS alone (HR 1.37; p < .001) while pre RT + LSS (HR 0.70; p < .001) and LSS + post RT (HR 0.72; p < .001) had improved OS vs LSS alone. Treatment at a comprehensive community, academic, or integrated network programs vs community program; private insurance vs none; Hispanic vs. non-Hispanic (HR 0.85, p = .048); and higher educational attainment were associated with improved OS. More comorbidities, other primary cancers, older age, and no transitions in care were associated with worse OS. Conclusions: The only racial/ethnic disparity identified when evaluating rates of Amp and OS for ESS was a small OS benefit for Hispanic pts. OS was inferior with Amp and best with LSS with either pre RT or post RT. OS was improved at non-community programs, potentially indicating a need for referral to experienced centers

Limb-sparing surgery plus radiotherapy results in superior survival: an analysis of patients with high-grade, extremity soft-tissue sarcoma from the NCDB and SEER
Small randomized trials have not shown an overall survival (OS) difference among local treatment modalities for patients with extremity soft-tissue sarcomas (E-STS) but were underpowered for OS. We examine the impact of local treatment modalities on OS and sarcoma mortality (SM) using two national registries. The National Cancer Database (NCDB) and the Surveillance, Epidemiology, and End Results (SEER) Program were analyzed separately to identify patients with stage II-III, high-grade E-STS diagnosed between 2004 and 2013 and treated with (1) amputation alone, (2) limb-sparing surgery (LSS) alone, (3) preoperative radiation therapy (RT) and LSS, or (4) LSS and postoperative RT. Multivariable analyses (MVAs) and 1:1 matched pair analyses (MPAs) examined treatment impacts on OS (both databases) and SM (SEER only). From the NCDB and SEER, 7828 and 2937 patients were included. On MVAs, amputation was associated with inferior OS and SM. Relative to LSS alone, both preoperative RT and LSS (HR, 0.70; 95% CI: 0.62-0.78) and LSS and postoperative RT (HR, 0.69; 95% CI: 0.63-0.75) improved OS in NCDB analyses with confirmation by SEER. Estimated median survivals from MPA utilizing NCDB data were 7.2 years with LSS alone (95% CI: 6.5-8.9 years) vs 9.8 years (95% CI: 9.0-11.2 years) with LSS and postoperative RT. A MPA comparing preoperative RT and LSS to LSS alone found median survivals of 8.9 years (95% CI: 7.9-not estimable) and 6.6 years (95% CI: 5.4-7.8 years). Optimal high-grade E-STS management includes LSS with preoperative or postoperative RT as evidenced by superior OS and SM
