Purpose: Alopecia is a distressing side effect of radiotherapy in patients undergoing treatment for primary brain tumours. This study aimed to investigate the most influential clinical, demographic, and dosimetric factors associated with permanent scalp alopecia in patients with brain tumours treated with intensity-modulated radiations.
Patients And Methods: Eighty patients with brain tumors treated with intensity-modulated radiations were enrolled.
Alopecia Induced by Fluoroscopy-guided Embolization: A Case Report.
Acta Med Philipp

Department of Dermatology, Philippine General Hospital, University of the Philippines Manila.
Article Synopsis
- - Alopecia due to radiation can occur 2-8 weeks after exposure, potentially being temporary or permanent depending on the radiation dose, with an increasing frequency observed in patients undergoing fluoroscopy-guided procedures
- - A case study of a 22-year-old female highlighted significant hair loss 12 days post-embolization for an arteriovenous malformation, with examination revealing characteristics typical of radiation-induced alopecia
- - After receiving a peak skin dose of 4.67 Gray, the patient was treated with topical minoxidil, which resulted in complete hair regrowth in six months, emphasizing the need for proper follow-up and safety protocols in patients exposed to radiation during medical procedures

The advent of fluoroscopically guided cardiology procedures has greatly improved patient outcomes but has also increased occupational radiation exposure for healthcare professionals, leading to adverse health effects such as radiation-induced cataracts, alopecia, and cancer. This emphasizes the need for effective radiation safety training. Traditional training methods, often based on passive learning, fail to simulate the dynamic catheterization laboratory environment adequately.

Background And Purpose: Radiation-induced alopecia (RIA) is one of the most frequent and upsetting cosmetic side effects after radiotherapy (RT) for brain cancer. We report the incidence of RIA in a cohort of brain tumours patients treated with Proton Therapy (PT) and externally validate published NTCP models of grade 2 (G2) RIA for their implementation in clinical practice.
Methods: Data for patients treated for brain tumours with scanning beam PT between 2018 and 2022 were extracted.
Helium Ion Therapy for Advanced Juvenile Nasopharyngeal Angiofibroma.

Heidelberg Ion-Beam Therapy Center (HIT), Heidelberg University Hospital, 69120 Heidelberg, Germany.
Helium ion therapy (HRT) is a promising modality for the treatment of pediatric tumors and those located close to critical structures due to the favorable biophysical properties of helium ions. This in silico study aimed to explore the potential benefits of HRT in advanced juvenile nasopharyngeal angiofibroma (JNA) compared to proton therapy (PRT). We assessed 11 consecutive patients previously treated with PRT for JNA in a definitive or postoperative setting with a relative biological effectiveness (RBE) weighted dose of 45 Gy (RBE) in 25 fractions at the Heidelberg Ion-Beam Therapy Center.
