"Neuroendocrine Dysfunction— Potential Consequences of Intracranial Diseases: The Case of Subarachnoid Hemorrhage and Tumors of the Sellar and Perisellar Regions"

Abstract: 

Neuroendocrine dysfunction can occur as a result of intracranial diseases when the hypothalamic-pituitary system is damaged. In the case of a subarachnoid hemorrhage, the hemorrhage itself, increased intracranial pressure, or circulatory disturbances can lead to hormone deficiencies. Tumors of the sellar and perisellar regions can impair the pituitary gland through growth or compression. Common consequences include hormone deficiencies such as ACTH, TSH, LH/FSH, or growth hormone deficiency, as well as water balance disorders (diabetes insipidus, SIADH). Clinically, these conditions manifest as fatigue, decreased performance, metabolic disorders, fertility problems, and a reduced quality of life. Therefore, early diagnosis and, if necessary, hormone replacement therapy are of great importance.

"Tradition, Precision, Innovation—Peripheral Nerves in Neurosurgery 2026"

Abstract: 

In the public perception, both within and outside of neurosurgery, peripheral nerves are often overshadowed by the “brain” and “spinal cord.” Nevertheless, they constitute a specialized and demanding subfield that requires the highest level of anatomical understanding, microsurgical skills, and interdisciplinary collaboration. This lecture spans 10 years of clinical and scientific work on peripheral nerves. First, it highlights modern experimental approaches in imaging that make it possible to visualize even the smallest nerve structures. Second, it discusses projects aimed at optimizing patient care outside the operating room.
