Even after considerable advances in the field of epilepsy treatment, convulsions are inefficiently controlled by standard drug therapy. Herein, a series of pyrimidine-carbothioamide derivatives 4(a-t) was designed as anticonvulsant agents by doing some important structural modifications in well-known anticonvulsant drugs. Two classical animal models were used for the in vivo anticonvulsant screening, maximum electroshock seizure (MES) and subcutaneous pentylenetetrazole (scPTZ) models; followed by motor impairment study by rotarod method...

Nesidioblastosis is the most common cause of non-transient, recurrent and persistent hypoglycaemia in neonates and infants. It is a disorder of diffuse proliferation of beta cells of the pancreas leading to hyperinsulinemia and hypoglycaemia. The main aim is to prevent the severe episodes of hypoglycaemia which can cause damage to the brain and/or mental retardation. In this case report we present two cases of nesidioblastosis and their perioperative anaesthetic course for near-total pancreatectomy. First case was a 7 months old female who had repeated episodes of convulsions since birth...

Adenosinergic signaling has important effects on brain function, anatomy, and physiology in both late and early stages of development. Exposure to caffeine, a non-specific blocker of adenosine receptor, has been indicated as a developmental risk factor. Disruption of adenosinergic signaling during early stages of development can change the normal neural network formation and possibly lead to an increase in susceptibility to seizures. In this work, morpholinos (MO) temporarily blocked the translation of adenosine receptor transcripts, adora1, adora2aa, and adora2ab, during the embryonic phase of zebrafish...

Intracranial hemorrhage is a rare complication of spinal surgery. Case 1 was a 58-year-old man who underwent cervical laminoplasty. No apparent iatrogenic dural rupture or cerebrospinal fluid leakage was observed. An hour after the surgery, the patient had convulsions and became restless thereafter. CT revealed an intracranial SAH. The patient recovered normal consciousness the next morning. Case 2 was a 68-year-old woman who underwent cervical laminoplasty without postoperative CSF leakage. Six days after the surgery, the patient continued to complain of nausea and headache...

Platelets play a key role in thrombosis and cardiovascular diseases. Medicinal plants could be one of the most important factors that influence risks for platelet activation. Buddleja globosa (known as "matico") is a medicinal plant with many biological activities. The high content of polyphenols suggest that matico could have antiplatelet activity. The present study was aimed at evaluating mechanisms of antiplatelet action of an extract of matico. We demonstrated that matico extract at low concentrations and in a concentration dependent manner (0...

BACKGROUND: Tonic-clonic convulsions and convulsive status epilepticus (currently defined as a tonic-clonic convulsion lasting at least 30 minutes) are medical emergencies and require urgent and appropriate anticonvulsant treatment. International consensus is that an anticonvulsant drug should be administered for any tonic-clonic convulsion that has been continuing for at least five minutes. Benzodiazepines (diazepam, lorazepam, midazolam) are traditionally regarded as first-line drugs and phenobarbital, phenytoin and paraldehyde as second-line drugs...

Hydrogen sulfide (H2S) is a colorless, highly neurotoxic gas. It is not only an occupational and environmental hazard but also of concern to the Department of Homeland Security for potential nefarious use. Acute high-dose H2S exposure causes death, while survivors may develop neurological sequelae. Currently, there is no suitable antidote for treatment of acute H2S-induced neurotoxicity. Midazolam (MDZ), an anti-convulsant drug recommended for treatment of nerve agent intoxications, could also be of value in treating acute H2S intoxication...

We report two cases of bilateral asymmetric optic disc coloboma (ODC) in siblings. The index patient is a 9-year-old Nigerian girl with severe cognitive deficit who presented with a poor vision of 3 years' duration. She had a history of childhood febrile convulsions and delayed developmental milestones. Her visual acuity could not be assessed because she had a cognitive deficit and expressive aphasia. Ocular examination revealed a very large excavated right optic disc with only a strip of remnant neuro-retinal rim superiorly, and a smaller left optic disc with inferior disc excavation, superior wedge of the pink neuro-retinal rim as well as a temporal optic disc pit...

In patients with epilepsy, depression is a common comorbidity but difficult to be treated because many antidepressants cause pro-convulsive effects. Thus, it is important to identify the risk of seizures associated with antidepressants. To determine whether paroxetine, a very potent selective serotonin reuptake inhibitor (SSRI), interacts with ion channels that modulate neuronal excitability, we examined the effects of paroxetine on Kv3.1 potassium channels, which contribute to highfrequency firing of interneurons, using the whole-cell patch-clamp technique...

Tobacco smoking is considered the greatest risk factor for early death caused by noncommunicable diseases. Currently, there are more than one billion tobacco smokers in the world predisposed to many diseases including heart attack, stroke, cancer, and premature birth or birth defects related to the consumption of cigarettes. However, studies on the association between tobacco smoking and seizures or epilepsy are insufficient and not well documented. In the present study, the authors examined the convulsive effects of the intracerebroventricular administration of cigarette smoke condensate (CSC, 2μl/Rat) in rats and compared it with the intensity of seizures in the kainic acid (KA)-induced seizure model of epilepsy...

Adverse neurological transfusion reactions including posterior reversible encephalopathy syndrome (PRES) following blood transfusion are rare. Our case an 18-year-female with known Factor X deficiency with menorrhagia developed severe hypertension, followed by generalised tonic clonic convulsions apparently after blood component transfusion. She had earlier received 4 units of red blood cells (RBC) for anaemia and 10 units of fresh frozen plasma (FFP) for menorrhagia (with prolonged PT and APTT) within short span of time at another hospital...

OBJECTIVE: Since the 1970s, intravenous (IV) phenytoin (PHT) has been traditionally used as second-stage treatment for convulsive status epilepticus (SE) after failure of benzodiazepines. The aim of this review was to critically assess the evidence supporting the use of IV PHT as treatment of convulsive SE in patients of any age. In particular, we critically appraised the results of randomized controlled trials (RCTs) evaluating IV PHT as treatment of convulsive SE. METHODS: Systematic search of the literature to identify RCTs evaluating IV PHT as treatment of convulsive SE in patients of any age...

PURPOSE OF THE STUDY: Though rare, children are susceptible to paroxysmal dyskinesias (PxDs) such as paroxysmal kinesigenic dyskinesia (PKD), and infantile convulsions and choreoathetosis (ICCA, also termed PKD/IC). PKD is characterized by recurrent attacks of involuntary movements mostly starting around puberty, and PKD/IC also presents with clusters of non-febrile seizures at ages between 3 and 12 months in addition to symptoms of PKD. Recent studies showed that the cause of PKD or PKD/IC could be proline-rich transmembrane protein 2 (PRRT2) gene mutations...
