Clinical trials demonstrated that D-serine administration improves schizophrenia symptoms, raising the possibility that altered levels of endogenous D-serine may contribute to the N-methyl D-aspartate receptor hypofunction thought to play a role in the disease. We hypothesized that cerebro-spinal fluid (CSF) D-serine levels are decreased in the patients due to reduced synthesis and/or increased...
Melancholic depression is a biologically homogeneous clinical entity in which structural brain alterations have been described. Interestingly, reports of structural alterations in melancholia include volume increases in Cerebro-Spinal Fluid (CSF) spaces.

CSF leaks in the ear are the result of an abnormal communication between subarachnoid and tympano mastoid areas, most of then as a result of trauma (90%). They mean a lisk of meningitis (4-50%) directly related to the etiology. Our aim is to present the CSF leak cases seen in our hospital in the last 2 years and a revision of their management. The main factor for a sucessful surgical repair is ...
