We report, in a clinical setting, the tigecycline concentration and area under the concentration-time curve (AUC) - both in blood and in cerebrospinal fluid (CSF) - of a patient with a ventriculo-atrial shunt infection. Tigecycline weakly penetrates CSF the CSF-to-serum concentration ratio was 0.079 and CSF-to-serum AUC(0-12) ratio was 0.067.

Objective: To gain initial insight into the efficacy to lower intracranial pressure (ICP), side effects, and effects on cognition of five drugs commonly used to treat idiopathic intracranial hypertension (IIH).
Background: Limited clinical data exist for the treatment for IIH. Impaired cognition is recognized in IIH and can be exacerbated by medications.

Background: Due to its availability and perceived safety, paracetamol is recommended even during pregnancy and for neonates. It is used frequently alone or in combination with other drugs required for the treatment of various chronic conditions. The aim of this study was to investigate potential effects of drug interactions on paracetamol metabolism and its placental transfer and entry into the developing brain.

Quantitative measurement of metabolites is essential to understand biological and disease processes. Absolute quantification by spiking heavy isotope-labeled internal standards and analyzing on mass spectrometry (MS) platform is a key method to determine the concentration of metabolites in biological samples. However, MS-based absolute quantification is often challenged by the commercial availability and high costs of isotope-labeled internal standards.

Encephalitis due to Epstein-Barr Virus (EBV) is a rare condition that primarily affects children and immunosuppressed patients. Diagnosing EBV encephalitis can be challenging due to its nonspecific clinical presentation and the lack of confirmatory tests. We present the case of a 66-year-old woman with a history of kidney transplantation who was admitted due to progressive subacute mental deterioration, preceded by vertigo and without fever.

The aim of this study was to explore an improved method for extracting rat cerebrospinal fluid (CSF), observing the impact on animal health under conditions of large-scale CSF collection and evaluating the feasibility of repeated collections. A total of 20 rats were anesthetized and fixed in a stereotactic frame. A 26G scalp needle, combined with a 1 mL syringe, was used to puncture the atlanto-occipital membrane and collect approximately 170 μL of CSF.
