Purpose: We aimed to investigate the effect of Helicobacter Pylorii (HP) on the development of gallbladder diseases and cholelithiasis and its relationship with gastritis.
Methods: 282 gastritis cases with follow-up and operated gallbladder material were included in the study. All histomorphological findings, presence of HP and other variables were compared. Active inflammation and presence of HP were examined in the gastritis group. The gallbladder (GB) disease group was evaluated in terms of cholelithiasis, inflammation, cholesterolosis, intestinal and pyloric metaplasia, and the presence of HP.
Results: Gallbladder HP (+) was higher in female patients than in male patients. The presence of HP in the GB was significantly higher in patients with cholelithiasis than patients without cholelithiasis. The incidence of HP in the GB was higher in patients with active gastritis than in patients with inactive gastritis. The presence of HP in the GB was found to be higher in patients with HP on gastric biopsy. HP was found to be less in cases without cholesterolosis in the GB (p

OBJECTIVE
Glioblastoma (GBM) is the most common and aggressive malignant primary brain tumor, and resection is a key part of the standard of care. In fluorescence-guided surgery (FGS), fluorophores differentiate tumor tissue from surrounding normal brain. The heme synthesis pathway converts 5-aminolevulinic acid (5-ALA), a fluorogenic substrate used for FGS, to fluorescent protoporphyrin IX (PpIX). The resulting fluorescence is believed to be specific to neoplastic glioma cells, but this specificity has not been examined at a single-cell level. The objective of this study was to determine the specificity with which 5-ALA labels the diversity of cell types in GBM.

METHODS
The authors performed single-cell optical phenotyping and expression sequencing–version 2 (SCOPE-seq2), a paired single-cell imaging and RNA sequencing method, of individual cells on human GBM surgical specimens with macroscopically visible PpIX fluorescence from patients who received 5-ALA prior to surgery. SCOPE-seq2 allowed the authors to simultaneously image PpIX fluorescence and unambiguously identify neoplastic cells from single-cell RNA sequencing. Experiments were also conducted in cell culture and co-culture models of glioma and in acute slice cultures from a mouse glioma model to investigate cell- and tissue-specific uptake and secretion of 5-ALA and PpIX.

RESULTS
SCOPE-seq2 analysis of human GBM surgical specimens revealed that 5-ALA treatment resulted in labeling that was not specific to neoplastic glioma cells. The cell culture further demonstrated that nonneoplastic cells could be labeled by 5-ALA directly or by PpIX secreted from surrounding neoplastic cells. Acute slice cultures from mouse glioma models showed that 5-ALA preferentially labeled GBM tumor tissue over nonneoplastic brain tissue with significant labeling in the tumor margins, and that this contrast was not due to blood-brain barrier disruption.

CONCLUSIONS
Together, these findings support the use of 5-ALA as an indicator of GBM tissue but question the main advantage of 5-ALA for specific intracellular labeling of neoplastic glioma cells in FGS. Further studies are needed to systematically compare the performance of 5-ALA to that of potential alternatives for FGS.

Published: September 2023

OBJECTIVE
Intraventricular meningiomas (IVMs) of the lateral ventricle are rare tumors that present surgical challenges because of their deep location. Visual field deficits (VFDs) are one risk associated with these tumors and their treatment. VFDs may be present preoperatively due to the tumor and mass effect (tumor VFDs) or may develop postoperatively due to the surgical approach (surgical VFDs). This institutional series aimed to review surgical outcomes following resection of IVMs, with a focus on VFDs.

METHODS
Patients who received IVM resection at one academic institution between the years 1996 and 2021 were retrospectively reviewed. Diffusion tensor imaging (DTI) reconstructions of the optic radiations around the tumor were performed from preoperative IVM imaging. The VFD course and resolution were documented.

RESULTS
Thirty-two adult patients underwent IVM resection, with gross-total resection in 30 patients (93.8%). Preoperatively, tumor VFDs were present in 6 patients, resolving after surgery in 5 patients. Five other patients (without preoperative VFD) had new persistent surgical VFDs postoperatively (5/32, 15.6%) that persisted to the most recent follow-up. Of the 5 patients with persistent surgical VFDs, 4 received a transtemporal approach and 1 received a transparietal approach, and all these deficits occurred prior to regular use of DTI in preoperative imaging.

CONCLUSIONS
New surgical VFDs are a common neurological deficit after IVM resection. Preoperative DTI may demonstrate distortion of the optic radiations around the tumor, thus revealing safe operative corridors to prevent surgical VFDs.
Long-term oncological outcomes for endoscopic endonasal versus open surgical approaches for anatomically matched, locally advanced stage T4 sinonasal malignancies with skull base involvement

Published: September 2023

OBJECTIVE
Expanded endoscopic approaches (EEAs) are increasingly used for the definitive management of sinonasal malignancies. EEAs, in appropriately selected cases, provide similar oncological outcomes but are associated with lower complication rates compared with open surgical approaches. Selection bias is a limitation reported in previous studies comparing EEAs and open surgical approaches for the management of sinonasal malignancies. To address this issue, in this study the authors compared the long-term oncological outcomes of an anatomically matched cohort of patients with locally advanced sinonasal malignancies with skull base involvement (T4 stage). The specific objective of this study was to investigate the extent of resection (EOR), overall survival (OS), and disease progression between the EEA and open surgical cohorts.

METHODS
A cohort of 42 patients with locally advanced sinonasal malignancies and skull base involvement (stage T4) and operated on via an EEA was matched anatomically with a cohort of 54 patients who had undergone open surgery. A retrospective chart review was conducted on these 96 patients who were treated between September 1993 and June 2020. All patients in the cohort were eligible for either an EEA or open surgery according to anatomical criteria. Patients of all ages were included, and the minimum follow-up required for eligibility was 4 months. Patients were excluded if surgery was not offered for curative intent and preoperative imaging did not demonstrate that gross-total resection was achievable.

RESULTS
There were more complications in the conventional surgery cohort than in the EEA cohort (33.33% vs 14.29%, p = 0.033). There was no significant difference in the EOR between the EEA and conventional surgery cohorts, as demonstrated by comparable rates of positive margins in both groups (5.56% vs 2.38%, respectively). Disease progression (hazard ratio [HR] 0.47, 95% CI 0.17–1.27, p = 0.137) was lower and OS (HR 0.58, 95% CI 0.26–1.29, p = 0.183) was higher in the EEA cohort, but these findings did not reach statistical significance.

CONCLUSIONS
The EEA was found to be associated with lower risks of complications than conventional craniofacial surgical approaches. There were no significant differences in OS and progression-free survival between the EEA and conventional surgical cohorts when comparing anatomically matched cohorts of patients with stage T4 sinonasal malignancies and skull base involvement.

OBJECTIVE
The aim of this study was to evaluate whether indirect revascularization in pediatric patients with moyamoya disease leads to periventricular anastomosis (PVA) regression, which is markedly developed in moyamoya vessels and is regarded as a risk factor for hemorrhage.

METHODS
Pediatric patients with moyamoya disease treated with indirect revascularization from 2011 to 2021 were included in this study. Magnetic resonance angiography and arterial spin labeling images acquired before and 1 year after surgery were assessed to obtain a visual scale of postoperative collateral artery formation, moyamoya vessels, PVA, and quantitative values of cerebral blood flow (CBF). The relationship between background information (age, sex, RNF213 p.R4810K variant status, and preoperative CBF) and postoperative collateral artery formation, as well as postoperative CBF improvement and regression of moyamoya vessels and PVA, was evaluated.

RESULTS
Of 89 hemispheres in 58 patients (34 females; mean [SD] patient age 8.0 [3.4] years), 74.2% showed good postoperative collateral artery formation and a significant increase in CBF (p < 0.001). Postoperative PVA showed significant regression (postoperative score 1.46 [1.06] vs 2.02 [1.69], p = 0.001), especially in those arising from choroidal arteries (postoperative score 0.28 [0.50] vs 0.72 [0.67], p < 0.001). Compared with hemispheres without good collateral artery formation, those with good collateral artery formation were more likely to show a higher increase in CBF (9.74 [12.44] ml/min/100 g vs −4.86 [9.68] ml/min/100 g, p < 0.001) and regression of PVA (54.5% [36/66] vs 30.4% [7/23], p = 0.015). Although not statistically significant, patients with postoperative PVA progression were younger than those with regression (6.75 [3.03] years vs 8.18 [3.17] years, p = 0.188), and patients with the RNF213 p.R4810K variant were more likely to show regression (28/57 [49.1%] hemispheres vs 5/13 [38.5%] hemispheres, p = 0.069).

CONCLUSIONS
Indirect revascularization in pediatric patients with moyamoya disease resulted in good collateral extracranial artery formation and an increase in CBF and PVA regression, especially of vessels arising from choroidal arteries. With good postoperative collateral artery development, patients were more likely to show improved CBF and regression of moyamoya vessels, including PVA. Whether postoperative PVA changes reduce future hemorrhage risk requires further investigation.
