The need for valproic acid as prophylaxis in neurosurgery patients.

Using anti-epileptic drugs in neurosurgery patients is a routine practice. This controlled trial aimed to assess whether prophylaxis with Valproate in brain surgery patients is justified or not. Group A (n=50; controls) patients received valproic acid postoperatively for three months, while group B (n=50; subjects) received a placebo. Serum valproic acid levels between 50-125g/ml were required. Kendall's Tau was applied to see the correlation between the 'frequency of seizures' between different surgical procedures performed and the extent of manipulations-EOMs. A wireless EMOTIV EPOC device was used to visualize the Electroencephalogram patterns. In controls, 12 patients had one seizure and only two patients had 2 seizures. In the placebo group, 13 patients had one and 4 patients had 2 seizures. The seizure frequency was highest amongst brain tumor patients. An insignificant difference was found between the seizure frequencies of the placebo and control groups. A statistically insignificant correlation was found between seizure frequency and independent variables: surgical procedures and EOM (%). Using an AED or not, the frequency of seizures did not substantially reduce over the postoperative period. If not necessary, the anti-epileptic medication that is frequently provided as a prophylactic against seizures in the post-operative period should not be administered.

Case report of a patient with 'one-and-a-half plus syndrome: nine syndrome'.

This case talks about 'One-and-a-half plus syndrome', a clinical syndrome affecting binocular vision and facial nerve. One-and-a-half plus syndrome is a less known clinical syndrome which constitutes of a conjugate horizontal gaze palsy in one direction and an internuclear ophthalmoplegia in the other direction. Despite the known association between ischemia, autoimmune disorders, multiple sclerosis, with mono neuritis multiplex resulting in extra ocular movement disorder, one-and-a-half plus syndrome is rarely considered in the differential diagnosis of eye ball movement disorders, as many clinicians are not able to diagnose such a case as ' the eyes don't see what the mind doesn't know'. Our report aims to raise awareness about connective tissue disorders presenting as neuro-ophthalmological syndrome, as early recognition can accelerate diagnosis and decrease the morbidity.
