Clostridium perfringens septic arthritis of the sternoclavicular joint has not been reported previously. We present the case of a 70-year-old patient with a history of stage IV colon cancer who presented to the emergency department with chest and neck pain for 3 days. After assessment, he was discharged home on analgesics. Within 24 h he returned, critically ill with C. perfringens septic arthritis of the left sternoclavicular joint and septic shock. Why Should an Emergency Physician Be Aware of This? Emergency physicians should be aware of the possibility of C. perfringens sternoclavicular joint septic arthritis in patients with unexplained chest, shoulder, or neck pain, especially when associated with a history of colorectal carcinoma or immunosuppression. A finding of C. perfringens bacteremia should prompt a search for occult gastrointestinal malignancy.

To investigate the prognostic factors and impact of adjuvant treatment on uterine carcinosarcoma (UCS). A retrospective review of UCS patients treated between 2005 and 2019 was conducted. International Federation of Gynecology and Obstetrics (FIGO) 2009 staging system was used. Multivariate stepwise Cox proportional hazard regression models were used to identify the independent predictors of overall survival (OS) and progression-free survival (PFS). A total of 138 patients were eligible for descriptive analysis. Excluding 12 patients without surgery, 126 patients with adequate clinicopathologic data were included for prognostic analysis. The median follow-up for survivors was 51.8 months. 5-year OS and PFS rates for FIGO stage I, II, III, IV were 64.5% and 51.8%, 60.8% and 57.7%, 47.7% and 45.9%, 5.1% and 4.1%, respectively. https://www.selleckchem.com/MEK.html By multivariate analysis, six models each for PFS and OS were formulated including highly correlated variables alternatively. Adjuvant chemoradiation was consistently selected as an independent prognostic factor for OS (hazard ratio [HR] 0.10-0.22, all p<0.001) and PFS (HR 0.12-0.23, all p<0.001), while adjuvant chemotherapy (HR 0.33-0.41), age≥58 years (HR 1.80-1.91), stage III/IV (HR 3.36-13.34), and adnexal metastasis (HR 2.06-5.02) in three to four of the six models for OS. Stratified analyses revealed that adjuvant chemoradiation significantly improved outcome compared with adjuvant chemotherapy for stage IA patients with lymphovascular space invasion and stage IB-IV, lymph node metastasis, and adnexal metastasis. Adjuvant chemoradiation was confirmed as an independent good prognostic factor, while older age, stage III/IV, and adnexal metastasis were associated with poor outcome in UCS. Adjuvant chemoradiation was confirmed as an independent good prognostic factor, while older age, stage III/IV, and adnexal metastasis were associated with poor outcome in UCS.Adequate dose homogeneity and full prescription dose delivery to the scalp still remains a dosimetric problem during scalp irradiation due to the anatomical shape of the cranium. Confounding variables such as gravity, the irregular and convex shape of the cranium, air gaps between scalp surface and commercial bolus, and potential inconsistencies in a 3D printed bolus can negatively impact the dose delivered to the scalp surface during scalp irradiation. The purpose of this retrospective case study was to implement the use of a 3D milled rigid bolus technique combined with volumetric modulated arc therapy (VMAT) treatment planning and evaluate the dosimetric efficacy in delivering dose to the surface of the scalp. The 8-patient retrospective case study consisted of patients with a scalp lesion treated using a 3D milled bolus, VMAT, 6 megavoltage (MV) photon beams, and aligned for treatment using daily conebeam computed tomography (CT) and 6° of freedom couch positioning. Dose volume histograms (DVHs) were used to evaluate maximum dose delivered to the planning target volumes (PTVs) while the dose homogeneity index (DHI) was calculated and compared to that of an ideal value of 1. The researchers evaluated the minimum dose delivered to the individual PTVs after plan normalization. The researchers found that the 3D milled bolus coupled with volumetric modulated arc therapy increased surface dose homogeneity, while also increasing the percentage of planning target volumes receiving full prescription dose. With statistically significant results, patient specific 3D milled rigid bolus offers a viable bolus option for treatment of superficial scalp lesions when combined with volumetric modulated arc therapy treatment planning. However, a larger sample size used in a scientific research study across multiple institutions would be desirable to validate these case study findings.COVID-19 brought telemedicine to the forefront of clinical cardiology. We aimed to examine the extent of trainees' involvement in and comfort with telemedicine practices in Canada with the use of a web-based self-administered survey. Eighty-six trainees from 12 training programs completed the survey (65% response rate). Results showed that before COVID-19, 39 trainees (45%) had telemedicine exposure, compared with 67 (78%) after COVID-19 (P less then 0.001). However, only 44 trainees (51%) reported being comfortable or very comfortable with the use of telemedicine. Of the 67 trainees who were involved in telemedicine, 4 (6%) had full supervision during virtual visits, 13 (19%) had partial supervision, and 50 (75%) had minimal or no supervision. Importantly, 67 trainees (78%) expressed the need for telemedicine-specific training and 64 (74%) were willing to have their virtual visits recorded for the purpose of evaluation and feedback. Furthermore, 47 (55%) felt strongly or very strongly positive about incorporating telemedicine into their future practice.
