Cerebellar Transcranial Direct Current Stimulation Does Not Alter Somatosensory Temporal Discrimination Threshold.

This study aimed to explore the role of the cerebellum on the somatosensory temporal discrimination (STD) process. Twenty healthy volunteers were enrolled in the study. Each participant was included in three different transcranial direct current stimulation (tDCS) sessions as anodal, cathodal, and sham sessions in randomised order. Anodal and cathodal cerebellar tDCS (cTDCS) were given for 20 min at an intensity of 2 mA. The results of the study indicate no effect of cTDCS on STD. Although the study results show that cTDCS does not affect STD, because of the restricted sample size of the study, it is useful and necessary to investigate this relationship more in depth in a larger healthy subject population using different cTDCS methodologies.

Endonasal endoscopic repair of ethmoid roof cerebrospinal fluid fistula by suturing the dura.

INTRODUCTION: Over the past 20years, improvement in surgical techniques as well advances in surgical instruments for sinus surgery has led to surgical closure of cerebrospinal fluid (CSF) leak using endoscopic approach. Minimally invasive and having lower post op morbidity, compared to traditional intracranial techniques, repairing CSF leak endoscopically has evolved to become the standard practice for management of CSF leak. DISCUSSION: Widespread use of endoscope in sinus surgery have made us more familiar with the anatomy of the sinuses as well as the skull base. In this paper, we will describe our experience of CSF repair by suturing dura under endoscopic guidance for the repair of small ethmoid roof (<1.2cm) defects.
