Abstract

Background: Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor in adultswith dismal prognosis due to the unavailability of an effective therapy. Up to now, there had been no definitive studies published on EGFR inhibition therapy as a chemosensitizer for GBM therapy using Temozolomide (TMZ). This study aims to reveal the most effective method and timing to administer TMZ anti EGFR targeted therapy which causes maximal DNA damage on GBM cells. Methods: Various regimens of anti EGFR monoclonal antibody Nimotuzumab (NMZ) was administered in different combinations with TMZ, performed on U87MG MGMT(+) EGFR(+) cells. The effectiveness of the combinations were evaluated by measuring yH2AX levels which reflects the degree of DNA damage. One-way Anova and LSD tests were performed to determine the effects of each treatment with p

Abstract

Introduction: Epilepsy is a manageable neurological disorder, but about one-third of cases are classified as drug-resistant epilepsy (DRE). DRE in pediatrics is more complex and may lead to cognitive function impairment, while surgery can offer seizure control in cases of focal DRE. Case: A 10-year-old male presented with a four-year history of recurrent seizures, thought to be caused by a left temporal cerebral cyst diagnosed five years earlier. During episodes, he experienced body stiffness, bilateral eye twitching, and drooling, with intact consciousness. After SARS-CoV-2 exposure, seizures became more frequent despite antiepileptic treatment, leading to partial resection of the left temporal lobe nine months later. Two years post epileptic surgery, he has become drug-responsive and achieved seizure control with symptomatic relief through medication. Discussion: Epilepsy is common in children, and DRE should be considered in cases of intractable epilepsy. Various factors can cause DRE, and in this patient, SARS-CoV-2 is thought to aggravate seizures by binding to ACE2 receptors in the central nervous system. This neural interaction may trigger reactive astrogliosis and neuroinflammation, disrupting the balance between glutamate and GABA levels. However, epilepsy surgery has been effective in improving the quality of life. Conclusion: Epilepsy surgery, either resective or non-resective surgery, is still rarely performed in Indonesia, while the management of DRE may require surgery. Although complete seizure freedom is not guaranteed, surgery can often convert DRE into a drug-responsive condition.
