Pediatric Glioma: Molecular Biology, Diagnosis and Treatment
A review by Dr. Alexandros Blionas examining pediatric brain tumors and their complex genetics and molecular biology. The paper links the molecular profile of these tumors to their diagnosis and management, showing how a precise understanding of tumor biology translates into more effective diagnosis and treatment of a group of tumors that remain among the […]
Rare Genetic Syndromes with Congenital Skull Aplasia
Published by Dr. Alexandros Blionas in Child’s Nervous System, the leading international journal in pediatric neurosurgery, this paper addresses extremely rare forms of congenital skull aplasia occurring in association with rare genetic syndromes. It sets out why these highly unusual cases demand a detailed understanding of the underlying pathophysiology if they are to be managed […]
Congenital Skull Aplasia: Surgical Management of a Rare Condition
Dr. Alexandros Blionas has published extensively in internationally recognized journals. In this paper, published in Surgical Neurology International, he examines cases of congenital skull aplasia in which management presents particular technical and clinical difficulty, and proposes a structured approach to their surgical treatment.
32nd Panhellenic Congress of Neurosurgery
Dr. Blionas was an invited speaker at the 32nd Panhellenic Congress of Neurosurgery, where he presented on mirror-image brain lesions and their surgical management through a single unilateral craniotomy — a technically demanding approach that addresses both lesions from one side, avoiding the need for a second procedure.
43rd Panhellenic Medical Congress
Dr. Blionas has spoken at numerous scientific congresses. At the 43rd Panhellenic Medical Congress he presented on three subjects: Shunt complications in hydrocephalus — a condition he manages regularly, and one in which the technical handling of complications requires particular care. Thoracic spine pathology — a specialized area of considerable clinical and surgical interest. Cerebral […]
The Appropriate Use of Spinal Fusion
Low back pain — sometimes accompanied by sciatica, pain radiating from the lower back down the leg — is among the most common reasons patients consult a spine surgeon. Imaging of the lumbar spine (MRI, CT, or flexion-extension radiographs) may then reveal spinal instability: vertebral displacement, slippage, or fractures that compromise normal vertebral movement. It […]
Neck Pain with Radiating Arm Pain — What to Watch For
Interview with Dr. Blionas, published in Proto Thema Cervical spine pathology and the significance of the spinal cord The fundamental difference between pathology of the cervical spine and pathology of the lumbar spine is that the neck houses the spinal cord. The cord is a critical structure, in the sense that it does not simply […]
Ozone Therapy for Sciatica & Lower Back Pain
Published in Eleftheros Typos · Co-authored with Dr. Michail Digenis, General Practitioner specializing in ozone therapy A note on the figures in this article. The percentages below describe the proportion of patients who improve. They are not the same as the additional benefit a treatment provides over and above natural recovery. Because sciatica improves on […]
Sciatica from Disc Herniation/Stenosis: Comparing Treatment Options
Many patients present with low back pain combined with leg pain; often the pain is confined either to the leg alone or to the lower back alone. These symptoms disrupt patients’ lives considerably — they are frequently unable to work, or to manage their daily activities. The first step with any symptom is to investigate […]
