Abstract
INTRODUCTION Trigeminal neuralgia (TGN) poses a therapeutic challenge, particularly within the context of multiple sclerosis (MS). This study aimed to conduct a comprehensive meta-analysis and systematic review of four less-invasive treatment modalities for TGN in MS patients, namely, gamma knife radiosurgery (GKRS), glycerol rhizotomy (GR), balloon compression (BC), and radiofrequency ablation (RFA). METHODS Single-armed meta-analyses were employed to assess the overall efficacy of each treatment, while double-armed analyses compared the efficacy between different treatment options in double-armed studies. Outcome evaluations included acute pain relief (within 1 month post-procedure), recurrence rates throughout 18 months of follow-up, and reported complication rates. RESULTS The meta-analysis revealed diverse outcomes for each intervention. GKRS demonstrated favorable outcomes, achieving a 77% success rate in alleviating pain among a pooled cohort of 863 patients, reinforcing its status as a viable therapeutic option. Additionally, GR, BC, and RFA exhibited efficacy, with success rates of 77%, 71%, and 80%, respectively, based on outcomes observed in 611, 385, and 203 patients. Double-armed analyses highlighted distinctions between the treatments, providing nuanced insights for clinical decision-making. CONCLUSION This meta-analysis provides a comprehensive overview of less-invasive treatments for TGN in MS patients. GKRS emerges as a leading option with comparable efficacy and fewer complications. However, the study underscores the nuanced efficacy and considerations associated with GR, BC, and RFA. The findings offer valuable insights for clinicians navigating treatment choices in this challenging patient population, considering acute pain relief, recurrence rates, and complication profiles.

Abstract
INTRODUCTION Gliomas continue to have a dismal prognosis. A myriad of genetic alterations has been described in this subset of tumors over the last decades. The integrative interpretation of the biomarker constellation for individual patients remains unclear. This study aims to evaluate the impact of some known genetic factors as prognostic biomarkers in grade 4 gliomas. METHODS Adult non-H3-altered grade 4 gliomas who underwent maximal safe resection accompanied by adjuvant therapy were successively enrolled since January 2019 till January 2021. Patient data were documented preoperatively and during the follow-up visits. The genetic profiling of the tumors included Isocitrate Dehydrogenase (IDH)-1 and IDH-2 mutation, MGMT promoter methylation rate, EGFR gene amplification and telomerase reverse transcriptase gene promoter (TERTp) mutation. RESULTS Mean Overall survival (OS) and Progression-free survival (PFS) were 14.45 ± 5.13 months (3-24 months) and 10.66 ± 4.87 months respectively. TERTp-mutant group had a significantly lower OS (10.9 vs. 15.9) and PFS (6.9 vs. 12.3) than TERTp wildtype group. In the TERT-mutant group, those with concomitant IDH wildtype tumor had higher OS and PFS, comparable to those with both TERTp and IDH wildtype tumors. In multivariate analysis, IDH mutation and TERTp wildtype status were predictive of longer OS and PFS. While IDH and absence of TERTp mutation were associated with KPS > 80 across the follow-ups, their predictive values were inferior to preoperative KPS scores. CONCLUSIONS TERTp mutation and IDH-wildtype status were associated with worse OS and PFS and lower follow-up KPS score in surgically resected gliomas, while MGMT and EGFR status did not have considerable prognostic value in this study.

Abstract
This case report describes our experience of surgical strategies of two patients with neglected subaxial cervical spine fracture-dislocation that came to our center with subsequent follow-ups. Subaxial cervical spine fracture-dislocation must be immediately diagnosed and treated. However, it can be neglected in some cases, especially in developing health care systems and patients with low socioeconomic status. We reported two neglected subaxial cervical fracture-dislocation with a mean age of 54 years old who presented with axial cervical pain, and decreased muscle forces. In one out of two, cervical closed traction was applied, then unsuccessful result led to circumferential decompression and fixation via anterior-posterior (AP) approach. Accordingly, we used AP approach without applying closed reduction in another patient successfully. Except one of our cases who died after 2 weeks of surgery due to aspiration pneumonia, other one found complete improvement at the end of 6-month follow-up. Our study emphasizes the importance of AP approach in patients with irreducible joint dislocations. The approach can minimize the surgical risks and increase the cost-benefit as compared to three or more staged approaches. Our approach is less intensive than some other AP approaches while is a safe and efficacious procedure since the posterior reduction is not performed before discectomy and decompression.

Abstract
BACKGROUND The existing data about language recovery in bilingual patients come from few studies on acute lesional deficits like stroke or traumatic injury. Still, little is known about the neuroplasticity potential of bilingual patients who undergo resection of gliomas affecting language-eloquent brain regions. In this study, we prospectively evaluated the pre- and postoperative language functions among bilinguals with eloquent region gliomas. METHODS We have prospectively collected the preoperative, 3-month and 6-month postoperative data from patients with tumors infiltrating the dominant hemisphere language areas during a 15-month period. Validated Persian/Turkish version of Western Aphasia Battery test and Addenbrooke Cognitive Examination were assessed for main language (L1) and second acquired languages (L2) in each visit. RESULTS Twenty-two right-handed bilingual patients were enrolled, and language proficiencies were assessed using mixed model analysis. On baseline and postoperative points, L1 had higher scores in all Addenbrooke Cognitive Examination and Western Aphasia Battery subdomains than L2. Both languages had deterioration at 3-month visit; however, L2 was significantly more deteriorated in all domains. At 6-month visit, both L1 and L2 showed recovery; however, L2 recovered to a less extent than L1. The single most parameter affecting the ultimate language outcome in this study was the preoperative functional level of L1. CONCLUSIONS This study shows L1 is less vulnerable to operative insults and L2 may be damaged even when L1 is preserved. We would suggest the more sensitive L2 be used as the screening tool and L1 be used for confirmation of positive responses during language mapping.

Abstract
Ablation surgeries are utilized to treat certain brain disorders. Recently, these surgeries have become more prevalent using techniques such as magnetic resonance guided focused ultrasound (MRgFUS) ablation and Gamma knife thalamotomy (GKT). However, as the thalamus plays a critical role in cognitive functions, the potential impact of these surgeries on functional connectivity and cognition is a matter of concern. Various approaches have been developed to locate the target for ablation and also investigate changes in functional connectivity before and after surgery. Functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) are widely used methods for assessing changes in functional connectivity and activity in clinical research. In this Review, we summarize the use of fMRI and EEG in thalamotomy surgeries. Our analysis shows that thalamotomy surgery can result in changes in functional connectivity in motor-related, visuomotor, and default-mode networks, as detected by fMRI. EEG data also indicate a reduction in over-activities observed in the preoperative state.

Abstract
AbstractIn this research, the photocatalytic degradation performance in a commercial low-density polyethylene (LDPE) film was investigated in the presence of zinc oxide (ZnO) nanoparticles grafted with two amounts of polyacrylamide. Fourier-transform infrared spectroscopy (FTIR) besides thermogravimetric analysis (TGA) test results reinforced the successful grafting of polyacrylamide to the extent of 10 and 39 wt.% on the ZnO nanoparticles. The photocatalytic degradation of the films under ultraviolet (UV) radiation was evaluated by characterizing the mechanical properties, weight loss, and morphology. The UV absorption and emission for ZnO nanoparticles were increased after grafting with 10% polyacrylamide. The tensile strength of the nanocomposite films increased with the incorporation of nanoparticles. The presence of ZnO nanoparticles in LDPE films increased the rate of degradation after 200 h of irradiation. The polyacrylamide grafting improved the dispersion of ZnO particles in LDPE matrix, whereas the increase of grafting extent from 10 to 39 wt.% reduced the photocatalytic performance of ZnO nanoparticles.

Abstract
BACKGROUND Progressive myoclonic epilepsy (PME) is a syndrome characterized by development of progressive myoclonus, cognitive impairment, and other neurologic deficits. Despite major advances in medical treatment of epilepsy, some PME patients remain refractory to antiepileptic drugs. This may further accentuate cognitive impairment and deteriorate functional capacity. Corpus callosotomy (CC) is used in patients with drug-resistant epilepsy who are not candidates for either excisional epilepsy surgery or neurostimulation. We report the application of the standard complete callosotomy to control medically refractory status epilepticus in a patient with PME. CASE DESCRIPTION A 16-year-old boy was referred to the emergency department with generalized tonic-clonic seizures. He was known to have PME since 5 years earlier, with frequent generalized seizures requiring hospitalization and reloading of the drugs. The patient was discussed by the epilepsy surgery working group, and corpus callosotomy was considered as a last resort to control the refractory status epilepticus. The patient experienced no generalized seizures during the 3-month postoperative period (Engel class IIIB). CONCLUSIONS Inasmuch as surgery was the last resort to control severe disabling status epilepticus, because most of the epileptogenic discharges were originating from the parieto-occipital regions and profound cognitive impairment was present, we decided to perform a complete rather than just an anterior callosotomy. CC may be considered to prevent secondary generalized seizures as the most disabling attacks in patients with certain epilepsy syndromes. Nevertheless, the impact of palliative surgical intervention on the overall disease course of patients with an underlying diffuse pathologic state remains to be determined.

Abstract
The occlusion of choice is a controversial topic in conventional complete denture (CCD) treatment. This study aimed to compare patient satisfaction with CCD with partially group-function occlusion (PGFO), fully bilateral balanced occlusion (FBBO), buccalised occlusion (BO), lingualised occlusion (LO) and the entire balanced group. Participants received new CCDs with PGFO. All steps of patient enrolment, denture fabrication, assessments during the follow-up period and data collection were carried out exactly the same as part 1 of this research project. All patients were recalled at 1 and 3 months after delivery for data collection using the shortened version of oral health impact profile for edentulous patients (OHIP-EDENT) questionnaire and 7 visual analog scales (VASs) for the quality of CCD based on general patient satisfaction, masticatory function, ability to speak, comfort, stability, retention and aesthetics. Data were analysed using the Wilcoxon signed-rank test, the Kruskal-Wallis test and Mann-Whitney test via SPSS version 18.0 (α = 0.05). Thirty participants completed the follow-up period for PGFO group. The mean age ± standard deviation of the new participants was 57.97 ± 6.93 years. Participants reported significantly less satisfaction in terms of comfort, stability and retention of denture with PGFO compared to balanced groups. Also, using OHIP-EDENT questionnaire, significantly higher physical pain score was noted for PGFO group compared to BO and LO. Higher physical disability score was noted in PGFO compared to LO. Participants receiving CCDs with PGFO reported lower satisfaction in terms of comfort, stability and retention of denture and higher physical pain and physical disability than the balanced occlusal schemes.

Abstract
Background and Purpose Treatment of life-threatening fungal infections caused by Candida species has become a major problem. Candida spp. are the most important causative agents of candidiasis. Allium tripedale is a medicinal plant that has been traditionally used to treat infections. In the present study, we aimed to determine the chemical compounds and antimicrobial activity of hydroalcoholic extract of A. tripedale against different species of Candida. Materials and Methods Phytochemical analysis was performed to identify the possible bioactive components of this extract by using gas chromatography and mass spectroscopy (GC-MS). The hydroalcoholic extract of A. tripedale were collected. Different concentrations of A. tripedale (50, 25, 12.5, and 6.25 mg/ml) were used to evaluate its antifungal activity against Candida species (C. albicans, C. parapsilosis, and C. krusei) using disk diffusion assay. Results The GC-MS analysis revealed the presence of 40 different phytoconstituents with peak area; the major compounds were tetracosane, hexadecanoic acid, 1-eicosanol, 1,2-dihydro-pyrido[3,2,1-kl]phenothiazin-3-one, 2-hexadecen-1-ol, and 3,7,11,15-tetramethyl. Hydroalcoholic extract showed strong antimicrobial activity (inhibition zone ⩾ 20 mm), moderate antimicrobial activity (inhibition zone < 12-20 mm), and no inhibition (zone < 12 mm). In addition, the hydroalcoholic extract exhibited the highest antimicrobial properties against C. albicans strains. Conclusion A. tripedale extract had a considerable inhibitory effect against various Candida species, but its highest inhibitory effect was against Candid albicans. Further investigations are required to detect the performance of this plant in the treatment of Candida infection.

Abstract
BACKGROUND Occlusal scheme can affect denture retention, stability, occlusal force distribution, aesthetics, masticatory function, patient comfort and general patient satisfaction with dentures. OBJECTIVES This study aimed to compare the patient satisfaction with 3 types of complete denture occlusion including fully bilateral balanced occlusion (FBBO), newly presented buccalised occlusion (BO) and lingualised occlusion (LO). METHODS In this parallel randomised clinical trial, new conventional complete dentures were fabricated for 86 volunteers. Participants were randomly allocated to 3 groups with 3 different occlusal schemes. All patients were recalled at 1 and 3 months after delivery for data collection. The 19-item version of Oral Health Impact Profile for Edentulous Patients questionnaire was used in this study. The visual analogue scale (VAS) was used for assessment of the prosthodontist's attitude towards denture quality, patient's attitude towards different occlusal schemes and evaluation of patient satisfaction. Data were analysed using the Wilcoxon signed rank test, the Kruskal-Wallis test and the post hoc Dunn test via SPSS version 18.0 (P ≤ .05). RESULTS Eighty-six patients completed the study, and their data were analysed (mean age ± standard deviation = 57.78 ± 9.98 years). The only significant difference when comparing the 3 groups was physical pain, which was significantly higher in FBBO group. No significant differences were found for the VAS scores of patient and prosthodontist satisfaction or the domain scores among the 3 occlusal schemes either at 1 or at 3 months post-delivery. The VAS score of patient satisfaction and prosthodontist satisfaction increased at third compared to first month after delivery. CONCLUSION The results of this randomised clinical trial provided evidence that BO is as effective as LO for the fabrication of complete dentures.

Abstract
Fusiform aneurysms of cerebral arteries are less prevalent than saccular aneurysms and are rarely associated with subarachnoid hemorrhage (SAH). In this article, we report SAH due to a rare case of bilateral fusiform aneurysm of the supraclinoid segment of the internal carotid arteries (ICAs) (C4 segment of the ICA).

Abstract
OBJECTIVES Limited evidence is available regarding mutual interactions between psychological factors and tooth loss. This study aimed to investigate the association between these two issues. METHOD In this 2011 cross-sectional study we obtained data from 4,585 adults who had completed information in 20 counties across Isfahan province, Iran, regarding tooth loss and psychological factors (depression, anxiety and stress level). To analyse the data ANOVA and multiple ordinal regression were applied. RESULTS After adjusting socio demographic factors, the association between depression (OR 1.23; 95% CI = 1.01,1.49), anxiety (OR 1.19; 95% CI = 1.03,1.38), and high stress level (OR 95% CI = 1.19; 1.01,1.39) remained significant. CONCLUSION We confirm the interaction between psychological factors and tooth loss, but recommend further studies on a national Iranian population.

Abstract
BACKGROUND Intrathecal injection of fluorescein is a useful adjuvant method for localization of fistulas in endoscopic endonasal repair of cerebrospinal fluid (CSF) leakage. Although being neurotoxic in commercial doses, a low dose of diluted fluorescein seems to be safe on the basis the existing data in the literature. OBJECTIVES The purpose of this study was to investigate the role of a low- dose intrathecal fluorescein injection in detection of CSF fistula and potential adverse effects of this technique. MATERIALS AND METHODS CSF rhinorrhea was repaired in 20 patients with an endoscopic endonasal technique. Intraoperative intrathecal fluorescein injection was used for localization of the site of the CSF leak. The accuracy rate of leakage site identification and the incidence of complications and recurrences were recorded. RESULTS Intrathecal administration of fluorescein demonstrated CSF leakage in 18 of the 20 patients (90%). There were no intraoperative complications. Definitive closure of the CSF leakage site was achieved in 16 patients (80%) after the initial reconstruction. Recurrence occurred in four cases and all patients were free of CSF leakage after the second surgical attempt. CONCLUSIONS The present study suggested that a low dose of intraoperative intrathecal fluorescein administration is a safe and sensitive method for localization of CSF leakage sites.
