Impact of Neck Dissection in Head and Neck Squamous Cell Carcinomas of Unknown Primary.

Purpose: Management of head and neck cancers of unknown primary (HNCUP) combines neck dissection (ND) and radiotherapy, with or without chemotherapy. The prognostic value of ND has hardly been studied in HNCUP.

Methods: A retrospective multicentric study assessed the impact of ND extent (adenectomy, selective ND, radical/radical-modified ND) on nodal relapse, progression-free survival (PFS) or survival, taking into account nodal stage.

Office Cystoscopy Urinary Tract Infection Rate and Cost before and after Implementing New Handling and Storage Practices.

Introduction: Based on 2010 American Urological Association recommendations our practice transitioned from sterile to high level disinfection flexible cystoscope reprocessing and from sterile to clean handling practices. We examined symptomatic urinary tract infection rate and cost before and after policy implementation.

Methods: We retrospectively reviewed 30-day outcomes following 1,888 simple cystoscopy encounters that occurred from 2007 to 2010 (sterile, 905) and 2012 to 2015 (high level disinfection, 983) at the Malcom Randall Veterans Affairs Medical Center.

Postoperative Radiation Therapy in Patients with Extracranial Chondrosarcoma: A Joint Study of the French Sarcoma Group and Rare Cancer Network.

Purpose: Postoperative radiation therapy (poRT) of intracranial/skull base chondrosarcomas (CHSs) is standard treatment. However, consensus is lacking for poRT in extracranial CHS (eCHS) owing to their easier resectability and intrinsic radioresistance. We assessed the practice and efficacy of poRT in eCHS.

Unilateral or bilateral irradiation in cervical lymph node metastases of unknown primary? A retrospective cohort study.

Introduction: Patients with cervical lymphadenopathy of unknown primary carcinoma (CUP) usually undergo neck dissection and irradiation. There is an ongoing controversy regarding the extent of nodal and mucosal volumes to be irradiated. We assessed outcomes after bilateral or unilateral nodal irradiation.

Effects of climate change on water resources in the upper Blue Nile Basin of Ethiopia.

Drawing on hydrology, rainfall, and climatic data from the past 25 years, this article investigates the effects of climate change on water resources in the transnational Blue Nile Basin (BNB). The primary focus is on determining the long-term temporal and seasonal changes in the flows of the Blue Nile in Ethiopia at the border to Sudan. This is important because the Blue Nile is the main tributary to the Nile river, the lifeline of both Sudan and Egypt.
