Penetrating craniocerebral injury caused by bladed weapons: Three homicide cases.

Penetrating craniocerebral injuries caused by a bladed weapon are rare events in western countries and often occur in the course of assault. We studied all homicide-related cases of cranial and brain injuries caused by bladed weapons that were seen at the Medicolegal Institute of Marseille over a 5-year period from 2014 to 2019. We found that such injuries are exceptional. The majority occur in the private sphere and are inflicted by men, as they require considerable force. They are rarely isolated but are accompanied by multiple cutting injuries of the thorax and abdomen. Such assaults leave imprints on the bone that can be analyzed using new anthropological techniques.

Stereotactic Body Radiotherapy for Frail Patients with Primary Renal Cell Carcinoma: Preliminary Results after 4 Years of Experience.

INTRODUCTION: The aim of this study was to report the oncological outcomes and toxicity of stereotactic body radiotherapy (SBRT) to treat primary renal cell carcinoma (RCC) in frail patients unfit for surgery or standard alternative ablative therapies. METHODS: We retrospectively enrolled 23 patients who had SBRT for primary, biopsy-proven RCC at our tertiary center between October 2016 and March 2020. Treatment-related toxicities were defined using CTCAE, version 4.0. The primary outcome was local control which was defined using the Response Evaluation Criteria in Solid Tumors. RESULTS: The median age, Charlson score and tumor size were 81 (IQR 79-85) years, 7 (IQR 5-8) and 40 (IQR 28-48) mm, respectively. The most used dose fractionation schedule was 35 Gy (78.3%) in five or seven fractions. The median duration of follow-up for all living patients was 22 (IQR 10-39) months. Local recurrence-free survival, event-free survival, cancer-specific survival and overall survival were 96 (22/23), 74 (18/23), 96 (22/23) and 83% (19/23), respectively. There were no grade 3-4 side effects. No patients required dialysis during the study period. No treatment-related deaths or late complications were reported. CONCLUSION: SBRT appears to be a promising alternative to surgery or ablative therapy to treat primary RCC in frail patients.

Povidone-iodine sclerotherapy of primary symptomatic lymphocele after kidney transplantation.

OBJECTIVE: To report the efficacy and safety of povidone-iodine sclerotherapy of primary symptomatic lymphocele after kidney transplantation in a large contemporary cohort study. PATIENTS AND METHODS: A single-institutional study was conducted including consecutive patients who underwent povidone-iodine sclerotherapy for primary symptomatic lymphocele after kidney transplantation between January 2013 and March 2020. Sclerotherapy was used as the first-line treatment of symptomatic lymphocele. Recurrent lymphoceles were managed with open or laparoscopic fenestration. The primary outcome was the efficacy of sclerotherapy which was defined as the absence of second sclerotherapy or salvage surgery. RESULTS: A total of 965 renal transplantations were included. Sclerotherapy for primary symptomatic lymphocele was performed in 60 cases (6.2%). The median (IQR) number of instillation, the volume of povidone-iodine per instillation and drainage time were 3 (3-3), 60 (38-80) mL and 6 days (5-8), respectively. Sclerotherapy related complications were reported in eight cases (13.3%) and included five cases of accidental catheter removal, two cases of lumbosciatica, and one case of intraperitoneal diffusion of povidone-iodine. After a median (IQR) follow-up of 33 (14-60) months, treatment success was achieved in 33 cases (55%). Multivariate analysis failed to identify predictors of sclerotherapy failure. Salvage therapies included 7 s sclerotherapy and 20 surgical fenestrations with an overall success rate of 88.8% (24/27). CONCLUSIONS: Sclerotherapy was an easy and safe procedure to treat primary symptomatic lymphocele in renal transplant recipients. Despite moderate efficacy, recurrences were easily controlled with salvage therapies. Further studies are necessary to identify predictive factors of sclerotherapy failure to directly refer patients to surgical treatment.
