Immunohistochemical Expression of IDH1, ATRX, Ki67, GFAP, and Prognosis in Indonesian Glioma Patients.

Background: The current World Health Organization (WHO) 2021 classification of human glioma is based on key molecular biomarkers to define neoplastic entities. This review further delineates mutant IDH (isocitrate dehydrogenase) from wild-type IDH disease, a necessity given the large survival gap between mutant IDH and wild-type IDH tumors. In Indonesia, there are currently few reports on the distribution and significance of these mutations. Therefore, this research aims to determine the relationship between IDH mutations, as well as clinicopathological and prognostic factors in patients with gliomas. Other immunohistochemical markers including ATRX (alpha-thalassemia/mental retardation, X-linked), Ki67 and GFAP (glial fibrillary acidic protein) expression were also evaluated. Methods: Forty-two glioma samples were collected from patients who underwent surgery at Dr. Kariadi General Hospital in Semarang, Central Java, Indonesia. Fresh and paraffin-embedded, formalin-fixed tissue samples were removed and sectioned for hematoxylin and eosin staining, immunohistochemistry, and IDH analysis of mutation. Medical records were used to collect clinicopathological and survival data. Results: IDH1 mutations were discovered in 32 (76,1%) patients, and those with IDH1 mutation had longer overall survival when corresponded to patients with IDH1-wild-type. Lower expression of Ki67 was discovered to be very associated with a better prognosis. Conclusion: IDH1 mutations status showed a significant relationship with prognosis in patients with glioma. Meanwhile, other markers (ATRX, Ki67, and GFAP) did not correlate with the prognosis.

Initiating an epilepsy surgery program with limited resources in Indonesia.

To share the experiences of organizing the epilepsy surgery program in Indonesia. This study was divided into two periods based on the presurgical evaluation method: the first period (1999-2004), when interictal electroencephalogram (EEG) and magnetic resonance imaging (MRI) were used mainly for confirmation, and the second period (2005-2017), when long-term non-invasive and invasive video-EEG was involved in the evaluation. Long-term outcomes were recorded up to December 2019 based on the Engel scale. All 65 surgical recruits in the first period possessed temporal lobe epilepsy (TLE), while 524 patients were treated in the second period. In the first period, 76.8%, 16.1%, and 7.1% of patients with TLE achieved Classes I, II, and III, respectively, and in the second period, 89.4%, 5.5%, and 4.9% achieved Classes I, II, and III, respectively, alongside Class IV, at 0.3%. The overall median survival times for patients with focal impaired awareness seizures (FIAS), focal to bilateral tonic-clonic seizures and generalized tonic-clonic seizures were 9, 11 and 11 years (95% CI: 8.170-9.830, 10.170-11.830, and 7.265-14.735), respectively, with p = 0.04. The utilization of stringent and selective criteria to reserve surgeries is important for a successful epilepsy program with limited resources.

Ozonated Aloe vera Oil Effective Increased the Number of Fibroblasts and Collagen Thickening in the Healing Response of Full-Thickness Skin Defects.

OBJECTIVE: This study aimed to examine the effectiveness of ozonated Aloe vera oil on the wound healing response of full-thickness defect tissue in Sprague-Dawley rats, assessed by collagen thickness and the number of fibroblasts. METHODS: This was an experimental research method using control groups and treatment groups with a posttest only control group design. The results showed that collagen thickness in wounds tended to increase, assessed on day 3 and day 7 using Masson's trichrome staining and microscopic evaluation. RESULTS: There was a significant difference in the number of fibroblasts between the two control and treatment groups on days 3 and 7 tested using one-way Kruskal-Wallis test, with a value of p=0.001(p < 0.05), resulting in a significant difference in wound size reduction between the groups. Further post hoc analysis using the Mann-Whitney test indicated a significant difference between the control groups and the treatment groups (P0, P1 versus P3, P4, P5, P8, P9, and P10) with a value of p=0.009(p < 0.05). CONCLUSIONS: Ozonated Aloe vera oil is effective in increasing the healing response of full-thickness defects, leading to the increase in the number of fibroblasts and collagen thickening that in turn accelerates wound healing in Sprague-Dawley rats.

Neuro-Endovascular Intervention in Traumatic Carotico-Cavernous Fistulae: A Single-Center Experience.

INTRODUCTION: The aim of this research was to describe a single-center practical experience in the management of traumatic carotid cavernous fistula (CCF). METHODS: There were a total of 31 patients between January 2005 and December 2019 with post-traumatic carotid cavernous sinus fistula (tCCF) who underwent treatment. We classified them into 2 types according to the flow of the CCF: patients with high flow CCF and patients with low flow CCF. RESULTS: Angiography revealed the high flow types on 21 patients (67.7%), the mean of patients ages are 31.5 years. Onyx embolization was performed in 1 patient (4.76%), transarterial balloon embolization was carried out in 10 patients (47.61%), transarterial coiling in 3 (14.28%) patients while 5 (28.8%) patients underwent transvenous routes to insert the coil and 2 patients (9.52%) were treated conservatively. Complete occlusion was achieved on all patients with coiling whereas the other treatment experiences the reducing flow of the fistula. We obtained 10 patients (32.2%) with a mean of 40.3 years as low flow type CCF. The patients with the low flow type mostly treated conservatively, because their symptoms were acceptable and intermittent. CONCLUSION: The ballooning currently became the more affordable treatment in our center. Balloon embolization was recommended for medium- and large-size fistula. The coils should be recommended for small-size fistula. In some cases occlusion of the fistula cannot be obtained using the detachable balloon, a coil can be used to occlude the cavernous sinus via trans arterial or trans venous access. If the fistula failed to be treated in traditional ways using balloons or coils, occlusion of the parent vessels could be another option.

Challenges in intradural disc herniation diagnosis and surgery: A case report.

INTRODUCTION: Intradural disc herniation (IDH) is a rare complication which comprises 0.27% of all herniated intervertebral discs. We are reporting a case of lumbar intradural disc herniation at the L4-L5 levels highlighting challenges in establishing clinical diagnosis and surgical approach involving a transdural microsurgery approach. PRESENTATION OF CASE: A 38-year-old gentleman was presented with left radicular low back pain without motoric and autonomic involvement admitted to our neurosurgical service. Spine MRI showed an intradural, extra-axial spinal mass. DISCUSSION: Lumbar IDH is a rare pathology thus often initially diagnosed as other more common conditions. In our case, the IDH diagnosis was confirmed during surgery as the radiological examination results mimic intradural extra-axial tumor. During surgery, a hard irregular white mass was found shortly after dural incision. Histopathological results showed chondrocytes, fibrotic and necrotic appearances consistent with the diagnosis of disc herniation. Postoperatively, the patient showed improvement and pain alleviation. CONCLUSION: We observed the beak sign which is one of the important features of IDH imaging. Surgery-wise, the challenge of dissecting the anterolateral part of the duramater from the annulus fibrosus of the intervertebral disc should be noted by the performing surgeon.

Seizure Outcomes in Patients with Complete versus Anterior Corpus Callosotomy: Analysis of Outcome.

INTRODUCTION: Corpus callosotomy (CCT) is a palliative procedure to treat injurious drop attacks or multifocal/generalized seizures in which resection of the epileptogenic focus is not feasible. We are presenting our experience in treating intractable epilepsy patients by CCT procedures. METHODS: We observed 16 patients who underwent callosotomy (male to female ratio 7:9; adult to pediatric ratio 3:13). Initial seizure frequency was reported ranged from 1 to 2 attacks daily to very often (more than 20 episodes daily). RESULTS: Our observation showed that among patients with drop attacks, complete and >90% seizure freedom was reported by 4 and 6 of 13 patients, respectively (76.9% combined). CONCLUSION: Our observation showed that corpus callosotomy yielded good outcome in patients with intractable epilepsy in Indonesia. Our observation showed total callosotomy achieved complete seizure freedom better compared to partial callosotomy patients.
