The role of the Ki-67 labelling index as an independent prognostic factor in indonesian glioma patients.

Introduction: Gliomas are the most common type of brain tumor. However, interpreting glioma morphology is subjective, and identifying mitosis can be challenging. This can impact the determination of the patient's tumor grade, therapy, and prognosis.

Dual manifestations: spinal and cerebellar hemangioblastomas indicative of von Hippel-Lindau syndrome.

Hemangioblastomas are rare, benign, and highly vascular tumors of the central nervous system, often associated with von Hippel-Lindau (VHL) syndrome, an autosomal dominant disorder characterized by multiple tumors. We present a case of a 32-year-old male with progressive headaches, visual disturbances, and motor deficits, who was diagnosed with multiple hemangioblastomas in the cervical-thoracic spinal cord and bilateral cerebellum through MRI. Surgical resection and histopathological biopsy confirmed the diagnosis.

Diagnostic Accuracy of Immunohistochemistry in Detecting MGMT Methylation Status in Patients with Glioma.

Background: The O6-methylguanine-DNA methyltransferase (MGMT) gene prevents mismatch in DNA replication and transcription by repairing mutagenic DNA lesions. MGMT is a predictor biomarker of chemotherapy in high-grade and low-grade gliomas based on high-risk clinical conditions. It also can be used for therapeutic decisions to predict hypermutation in recurrence in newly diagnosed low-grade gliomas.

Comparison of Polymerase Chain Reaction-Restriction Fragment Length Polymorphism, Immunohistochemistry, and DNA Sequencing for the Detection of IDH1 Mutations in Gliomas.

Background: IDH1 mutation shows diagnostic, prognostic, and predictive value in gliomas. Direct Sanger sequencing is considered the gold standard to detect IDH1 mutation. However, this technology is not available in most neuropathological centers in developing countries such as Indonesia.

Neurosurgery Services in Dr. Sardjito General Hospital, Yogyakarta, Indonesia, During the COVID-19 Pandemic: Experience from a Developing Country.

Background: Most articles describing the effect of the coronavirus disease 2019 (COVID-19) pandemic on neurosurgical services have been from developed countries. We report our experience in carrying out neurosurgical services at Dr. Sardjito General Hospital, Yogyakarta, Indonesia, during the time of the pandemic.

Neurosurgery residency program in Yogyakarta, Indonesia: improving neurosurgical care distribution to reduce inequality.

Objective: Educating future neurosurgeons is of paramount importance, and there are many aspects that must be addressed within the process. One of the essential issues is the disproportion in neurosurgical care, especially in low- and middle-income countries (LMICs). As stated in their report "Global Surgery 2030," The Lancet Commission on Global Surgery has emphasized that the availability of adequate neurosurgical care does not match the burden of neurosurgical disease.
