External beam radiation therapy (EMRT) is effective for the treatment of localized prostate cancer. Lower urinary tract infections (LUTIs) are considered one of the main possible adverse events related to External beam radiation therapy. Here we analyzed the incidence of LUTI during EMRT. Urinary tract infection was assumed when the findings of bacteriuria exceeded 100,000 units/mL, accompanied by specific cystitis symptoms. Among the total 540 analyzed patient, 208 (38.5%) developed a LUTI. E. coli was the main microorganism involved in LUTIs (102, 49...

Actinic keratosis (AK) is a common skin condition that results from exposure to chronic ultraviolet (UV) radiation. AK is characterized by visible, scaly lesions; sub-clinical lesions may also be present within a field of UV-exposed skin. These lesions exist on a disease continuum with squamous cell carcinoma. Field therapies, such as ingenol mebutate, aim to treat the visible and sub-clinical lesions within an area of sun-damaged skin. Areas covered: According to the SmPC, ingenol mebutate has a proposed dual mechanism of action that induces cell death necrosis with the production of a local pro-inflammatory response and stimulation of apoptosis...

Life expectancy of patients treated for brain tumors has lengthened due to the therapeutic improvements. Cognitive impairment has been described following brain radiotherapy, but the mechanisms leading to this adverse event remain mostly unknown. Technical evolutions aim at enhancing the therapeutic ratio. Sparing of the healthy tissues has been improved using various approaches; however, few dose constraints have been established regarding brain structures associated with cognitive functions. The aims of this literature review are to report the main brain areas involved in cognitive adverse effects induced by radiotherapy as described in literature, to better understand brain radiosensitivity and to describe potential future improvements...
