Objective is to study the interest of copeptin dosage as an early predictive marker for the diagnosis of post-operatice diabetes insipidus in trans-sphenoidal endoscopic pituitary surgery.

Patients of the Department of Neurosurgery, University of Erlangen-Nuremberg, undergoing surgery for sellar lesions were prospectively included. The study protocol was approved by the local Ethical Committee (Re.-No. 103_12 BC). Informed written consent was given by the participants or the

Any adult patient with a pituitary adenoma (either non-functioning, prolactin-secreting, growth hormone secreting, gonadotropin secreting, or TSH (thyroid stimulating hormone) secreting) or cyst scheduled to undergo transsphenoidal resection will be included in the study. Patients with chronic

Disorders of sodium and water balance are one of the commonly encountered problems while managing patients with neurological diseases. Managing such problems are challenging because the pathophysiology behind these disorders are complex and poorly understood and treatment of the injured brain itself

Fluid therapy is aimed to compensate for fasting which is required for surgery, to meet the ongoing fluid losses and to maintain electrolyte balance during surgery. Fluid deficit of a healthy child who is not fed parenterally may be estimated by multiplying hourly maintenance requirement for fluid

Introduction The neurohypophysial hormone arginine vasopressin (AVP), also known as antidiuretic hormone, was one of the first hormone identified for its vasopressin properties in 1895 by Oliver and Schäfer. They showed that extract of pituitary gland increased blood pressure in anesthetized dogs.

Hyponatremia occurs frequently in patients with acute brain injury in the days to weeks following the acute injury, and may contribute to adverse outcome (1). In addition, hyponatremia can aggravate neurologic dysfunction, complicate neurological assessments, and contribute to neurologic symptoms

Background: In the emergency setting, non-traumatic headache (NTH) is in 80% a benign symptom, but serious causes have to be ruled out. Copeptin, as a surrogate marker for antidiuretic hormone (ADH), is a marker for the individual stress level, even more subtle than cortisol. As a prognostic stress

PRIMARY OBJECTIVES: I. Determine the efficacy of an intensive chemotherapy regimen (based on POG-9412) for pediatric patients with intermediate-risk relapsed B-precursor acute lymphoblastic leukemia. SECONDARY OBJECTIVES: I. To determine levels of minimal residual disease (MRD) present at the end of
