Abstract
OBJECTIVE This study was conducted to investigate the impact of antiplatelet administration in the periprocedural period on the occurrence of thromboembolic complications (TECs) in patients undergoing treatment using the Woven EndoBridge (WEB) device for intracranial wide-necked bifurcation aneurysms. The primary objective was to assess whether the use of antiplatelets in the pre- and postprocedural phases reduces the likelihood of developing TECs, considering various covariates. METHODS A retrospective multicenter observational study was conducted within the WorldWideWEB Consortium and comprised 38 academic centers with endovascular treatment capabilities. Univariable and multivariable logistic regression analyses were performed to determine the association between antiplatelet use and TECs, adjusting for covariates. Missing predictor data were addressed using multiple imputation. RESULTS The study comprised two cohorts: one addressing general thromboembolic events and consisting of 1412 patients, among whom 103 experienced TECs, and another focusing on symptomatic thromboembolic events and comprising 1395 patients, of whom 50 experienced symptomatic TECs. Preprocedural antiplatelet use was associated with a reduced likelihood of overall TECs (OR 0.32, 95% CI 0.19-0.53, p < 0.001) and symptomatic TECs (OR 0.49, 95% CI 0.25-0.95, p = 0.036), whereas postprocedural antiplatelet use showed no significant association with TECs. The study also revealed additional predictors of TECs, including stent use (overall: OR 4.96, 95% CI 2.38-10.3, p < 0.001; symptomatic: OR 3.24, 95% CI 1.26-8.36, p = 0.015), WEB single-layer sphere (SLS) type (overall: OR 0.18, 95% CI 0.04-0.74, p = 0.017), and posterior circulation aneurysm location (symptomatic: OR 18.43, 95% CI 1.48-230, p = 0.024). CONCLUSIONS The findings of this study suggest that the preprocedural administration of antiplatelets is associated with a reduced likelihood of TECs in patients undergoing treatment with the WEB device for wide-necked bifurcation aneurysms. However, postprocedural antiplatelet use did not show a significant impact on TEC occurrence.

Dual Layer vs Single Layer Woven EndoBridge Device in the Treatment of Intracranial Aneurysms: A Propensity Score-Matched Analysis. Neurosurg Rev 2024; 47:116.

Abstract
BACKGROUND The Woven EndoBridge (WEB) devices have been used for treating wide neck bifurcation aneurysms (WNBAs) with several generational enhancements to improve clinical outcomes. The original device dual-layer (WEB DL) was replaced by a single-layer (WEB SL) device in 2013. This study aimed to compare the effectiveness and safety of these devices in managing intracranial aneurysms. METHODS A multicenter cohort study was conducted, and data from 1,289 patients with intracranial aneurysms treated with either the WEB SL or WEB DL devices were retrospectively analyzed. Propensity score matching was utilized to balance the baseline characteristics between the two groups. Outcomes assessed included immediate occlusion rate, complete occlusion at last follow-up, retreatment rate, device compaction, and aneurysmal rupture. RESULTS Before propensity score matching, patients treated with the WEB SL had a significantly higher rate of complete occlusion at the last follow-up and a lower rate of retreatment. After matching, there was no significant difference in immediate occlusion rate, retreatment rate, or device compaction between the WEB SL and DL groups. However, the SL group maintained a higher rate of complete occlusion at the final follow-up. Regression analysis showed that SL was associated with higher rates of complete occlusion (OR: 0.19; CI: 0.04 to 0.8, p = 0.029) and lower rates of retreatment (OR: 0.12; CI: 0 to 4.12, p = 0.23). CONCLUSION The WEB SL and DL devices demonstrated similar performances in immediate occlusion rates and retreatment requirements for intracranial aneurysms. The SL device showed a higher rate of complete occlusion at the final follow-up.

Abstract
BACKGROUND Mechanical thrombectomy (MT) for acute ischemic stroke is generally avoided when the expected infarction is large (defined as an Alberta Stroke Program Early CT Score of <6). OBJECTIVE To perform a meta-analysis of recent trials comparing MT with best medical management (BMM) for treatment of acute ischemic stroke with large infarction territory, and then to determine the cost-effectiveness associated with those treatments. METHODS A meta-analysis of the RESCUE-Japan, SELECT2, and ANGEL-ASPECT trials was conducted using R Studio. Statistical analysis employed the weighted average normal method for calculating mean differences from medians in continuous variables and the risk ratio for categorical variables. TreeAge software was used to construct a cost-effectiveness analysis model comparing MT with BMM in the treatment of ischemic stroke with large infarction territory. RESULTS The meta-analysis showed significantly better functional outcomes, with higher rates of patients achieving a modified Rankin Scale score of 0-3 at 90 days with MT as compared with BMM. In the base-case analysis using a lifetime horizon, MT led to a greater gain in quality-adjusted life-years (QALYs) of 3.46 at a lower cost of US$339 202 in comparison with BMM, which led to the gain of 2.41 QALYs at a cost of US$361 896. The incremental cost-effectiveness ratio was US$-21 660, indicating that MT was the dominant treatment at a willingness-to-pay of US$70 000. CONCLUSIONS This study shows that, besides having a better functional outcome at 90-days' follow-up, MT was more cost-effective than BMM, when accounting for healthcare cost associated with treatment outcome.

Abstract
OBJECTIVE Since mastoid bone aeration is a pressure buffer for the middle ear, it can be accepted as a prognostic factor for tympanoplasty. Temporal bone computed tomography (TBCT) is a primary method for estimating mastoid aeration. However, due to the risk of radiation and its high cost, there is a need for a more straightforward, faster, and more reliable method in non-complicated chronic otitis media cases (COM). Tympanometric volume measurement might be used for this purpose. This study investigated tympanometric volume measurement's reliability in showing mastoid bone aeration by comparing tympanometric volume measurement with TBCT aeration grading. PATIENTS AND METHODS Preoperative tympanometric volume measurements were performed in patients who underwent audiological examination and temporal computerized tomography (CT) with the diagnosis of COM and sequela of COM without discharge for the last three months and were indicated for surgery. CT was classified into six grades: grade 0: there is no aeration, sclerotic mastoid; grade 1: pneumatization only in the mastoid antrum; grade 2: <25% pneumatization; grade 3: 25-50% pneumatization; grade 4: >50 pneumatization, grade 5: full pneumatization. Averages of tympanometric volume values were determined according to CT degrees. RESULTS 48 left and 52 right ears (n: 100) of 81 patients, 24 females and 57 males, were included in the study. The mean age was 37.69±13.38. Mastoid pneumatization grades of patients were 32 grade 0, 23 grade 1, 16 grade 2, 14 grade 3, 11 grade 4, and 4 grade 5, respectively. Each grade's mean tympanometric volume (mL) was grade 0: 1.1594, grade 1: 1.6991, grade 2: 2.2250, grade 3: 3.0471, grade 4: 4.0327, and grade 5: 2.9775. CONCLUSIONS There is a statistically significant relationship between tympanometrically measured ear volume and mastoid degrees of pneumatization on temporal bone tomography. As the degree of mastoid aeration increases, the tympanometric volume also increases. According to the results of this study, tympanometric air volume can be used reliably in the preoperative evaluation of mastoid bone aeration in cases of simple COM without ear drainage.

Abstract
PURPOSE The fragility index (FI) measures the robustness of randomized controlled trials (RCTs). It complements the P value by taking into account the number of outcome events. In this study, the authors measured the FI for major interventional radiology RCTs. METHODS Interventional radiology RCTs published between January 2010 and December 2022 relating to trans-jugular intrahepatic portosystemic shunt, trans-arterial chemoembolization, needle biopsy, angiography, angioplasty, thrombolysis, and nephrostomy tube insertion were analyzed to measure the FI and robustness of the studies. RESULTS A total of 34 RCTs were included. The median FI of those studies was 4.5 (range 1-68). Seven trials (20.6%) had a number of patients lost to follow-up that was higher than their FI, and 15 (44.1%) had a FI of 1-3. CONCLUSION The median FI, and hence the reproducibility of interventional radiology RCTs, is low compared to other medical fields, with some having a FI of 1, which should be interrupted cautiously.

Abstract
The Woven EndoBridge (WEB) device has been widely used to treat intracranial wide neck bifurcation aneurysms. Initial studies have demonstrated that approximately 90% of patients have same or improved long-term aneurysm occlusion after the initial 6-month follow up. The aim of this study is to assess the long-term follow-up in aneurysms that have achieved complete occlusion at 6 months. We also compared the predictive value of different imaging modalities used. This is an analysis of a prospectively maintained database across 13 academic institutions. We included patients with previously untreated cerebral aneurysms embolized using the WEB device who achieved complete occlusion at first follow-up and had available long-term follow-up. A total of 95 patients with a mean age of 61.6 ± 11.9 years were studied. The mean neck diameter and height were 3.9 ± 1.3 mm and 6.0 ± 1.8 mm, respectively. The mean time to first and last follow-up was 5.4 ± 1.8 and 14.1 ± 12.9 months, respectively. Out of all the aneurysms that were completely occluded at 6 months, 84 (90.3%) showed complete occlusion at the final follow-up, and 11(11.5%) patients did not achieve complete occlusion. The positive predictive value (PPV) of complete occlusion at first follow was 88.4%. Importantly, this did not differ between digital subtraction angiography (DSA), magnetic resonance angiography (MRA), or computed tomography angiography (CTA). This study underlines the importance of repeat imaging in patients treated with the WEB device even if complete occlusion is achieved short term. Follow-up can be performed using DSA, MRA or CTA with no difference in positive predictive value.

Abstract
BACKGROUND AND PURPOSE Flow diversion has gradually become a standard treatment for intracranial aneurysms of the anterior circulation. Recently, the off-label use of the flow diverters to treat posterior circulation aneurysms has also increased despite initial concerns of rupture and the suboptimal results. This study aimed to explore the change in complication rates and treatment outcomes across time for posterior circulation aneurysms treated using flow diversion and to further evaluate the mechanisms and variables that could potentially explain the change and outcomes. MATERIALS AND METHODS A retrospective review using a standardized data set at multiple international academic institutions was performed to identify patients with ruptured and unruptured posterior circulation aneurysms treated with flow diversion during a decade spanning January 2011 to January 2020. This period was then categorized into 4 intervals. RESULTS A total of 378 procedures were performed during the study period. Across time, there was an increasing tendency to treat more vertebral artery and fewer large vertebrobasilar aneurysms (P = .05). Moreover, interventionalists have been increasingly using fewer overlapping flow diverters per aneurysm (P = .07). There was a trend toward a decrease in the rate of thromboembolic complications from 15.8% in 2011-13 to 8.9% in 2018-19 (P = .34). CONCLUSIONS This multicenter experience revealed a trend toward treating fewer basilar aneurysms, smaller aneurysms, and increased usage of a single flow diverter, leading to a decrease in the rate of thromboembolic and hemorrhagic complications.

Abstract
First-principles calculations coupled with Monte Carlo simulations are used to probe the role of a surface CO monolayer formation on secondary electron emission (SEE) from Cu, Ag, and Au (110) materials. It is shown that formation of such a layer increases the secondary electron emission in all systems. Analysis of calculated total density of states (TDOS) in Cu, Ag, and Au, and partial density of states (PDOS) of C and O confirm the formation of a covalent type bonding between C and O atoms. It is shown that such a bond modifies the TDOS and extended it to lower energies, which is then responsible for an increase in the probability density of secondary electron generation. Furthermore, a reduction in inelastic mean free path is predicted for all systems. Our predicted results for the secondary electron yield (SEY) compare very favorably with experimental data in all three materials, and exhibit increases in SEY. This is seen to occur despite increases in the work function for Cu, Ag, and Au. The present analysis can be extended to other absorbates and gas atoms at the surface, and such analyses will be present elsewhere.

Abstract
BACKGROUND The Woven EndoBridge (WEB) device has Food and Drug Administration approval for treatment of wide-necked intracranial bifurcation aneurysms. The WEB device has been shown to result in adequate occlusion in bifurcation aneurysms overall, but its usefulness in the individual bifurcation locations has been evaluated separately only in few case series, which were limited by small sample sizes. OBJECTIVE To compare angiographic and clinical outcomes after treatment of bifurcation aneurysms at various locations, including anterior communicating artery (AComA), anterior cerebral artery (ACA) bifurcation distal to AComA, basilar tip, internal carotid artery (ICA) bifurcation, and middle cerebral artery (MCA) bifurcation aneurysms using the WEB device. METHODS A retrospective cohort analysis was conducted at 22 academic institutions worldwide to compare treatment outcomes of patients with intracranial bifurcation aneurysms using the WEB device. Data include patient and aneurysm characteristics, procedural details, angiographic and functional outcomes, and complications. RESULTS A total of 572 aneurysms were included. MCA (36%), AComA (35.7%), and basilar tip (18.9%) aneurysms were most common. The rate of adequate aneurysm occlusion was significantly higher for basilar tip (91.6%) and ICA bifurcation (96.7%) aneurysms and lower for ACA bifurcation (71.4%) and AComA (80.6%) aneurysms (p=0.04). CONCLUSION To our knowledge, this is the most extensive study to date that compares the treatment of different intracranial bifurcation aneurysms using the WEB device. Basilar tip and ICA bifurcation aneurysms showed significantly higher rates of aneurysm occlusion than other locations.

Abstract
Preoperative embolization of hypervascular bone metastasis is an effective measure for reducing blood loss during open orthopedic surgery. When the clinician is experienced with the procedure, the risks of the procedure are minimal and final outcomes are typically good. In this study, we report a case of a 50-year-old female patient who presented with a delayed metastatic renal cell tumor in the left proximal femur one year after radical nephrectomy. The patient underwent an effective preoperative embolization, which resulted in a remarkable absence of bleeding and a successful response subsequent to surgical fixation.

Abstract
OBJECTIVE Transradial access (TRA) is commonly utilized in neurointerventional procedures. This study compared the technical and clinical outcomes of the use of TRA versus those of transfemoral access (TFA) for intracranial aneurysm embolization with the Woven EndoBridge (WEB) device. METHODS This is a secondary analysis of the Worldwide WEB Consortium, which comprises multicenter data related to adult patients with intracranial aneurysms who were managed with the WEB device. These aneurysms were categorized into two groups: those who were treated with TRA or TFA. Patient and aneurysm characteristics and technical and clinical outcomes were compared between groups. Propensity score matching (PSM) was used to match groups according to the following baseline characteristics: age, sex, subarachnoid hemorrhage, aneurysm location, bifurcation aneurysm, aneurysm with incorporated branch, neck width, aspect ratio, dome width, and elapsed time since the last follow-up imaging evaluation. RESULTS This study included 682 intracranial aneurysms (median [interquartile range] age 61.3 [53.0-68.0] years), of which 561 were treated with TFA and 121 with TRA. PSM resulted in 65 matched pairs. After PSM, both groups had similar characteristics, angiographic and functional outcomes, and rates of retreatment, thromboembolic and hemorrhagic complications, and death. TFA was associated with longer procedure length (median 96.5 minutes vs 72.0 minutes, p = 0.006) and fluoroscopy time (28.2 minutes vs 24.8 minutes, p = 0.037) as compared with TRA. On the other hand, deployment issues were more common in those treated with TRA, but none resulted in permanent complications. CONCLUSIONS TRA has comparable outcomes, with shorter procedure and fluoroscopy time, to TFA for aneurysm embolization with the WEB device.

Abstract
AIM Although the bifrontal approach used to be recommended for large olfactory groove meningioma (OGM), recent studies showed that large OGMs can also be resected safely via unilateral approaches. The present study aimed to discuss reasons for preferring a unilateral frontotemporal approach (UFTA), and the technical nuances and results of the UFTA, based on 18 cases. MATERIAL AND METHODS The clinical and surgical data of patients who had been operated on for large (4-6cm) or giant (>6cm) OGM via a UFTA between 2011 and 2018 were retrospectively collected. RESULTS In all, 18 patients were included. All tumors were compatible with a diagnosis of OGM in the light of peri-operative examinations. 11 cases (61%) were large and 7 (39%) giant OGM; mean diameter was 6.1cm (range, 4-10cm). Resection extent was Simpson grade II in 14 cases (78%), grade III in 1 (5%), and grade IV in 3 (17%). Sixteen cases (89%) had no peri-operative complications, while 2 patients (11%) showed cerebrospinal fluid leakage and hemorrhagic deposition in the surgical area. There were no new neurological deficits nor deaths. CONCLUSION The UFTA for OGM is a relatively safe and effective approach, ensuring a high total removal rate with low mortality and morbidity. This study, with a reasonable number of patients, is one of the few in the literature on the outcome of this approach.

Abstract
One of the main impacts of urban sprawl in rapidly growing countries has been contamination of coastal environments by waterborne pathogens, posing a critical risk to ecosystem and human health. Microbial source tracking (MST) has been a robust tool to identify the origin of these pathogens globally. This study compared the occurrence of a human-associated Bacteroides marker (BT-α) with faecal indicator bacteria (FIB) in an urban estuary (Golden Horn, Istanbul, Turkey). Faecal coliform (culture method), enterococci (both culture and qPCR method) concentrations and physicochemical variables were compared with the BT-α concentrations in monthly collected samples for a year (n = 108). Enterococci concentrations detected by culture and qPCR were positively correlated (r = 0·86, P < 0·01) suggesting that qPCR can be an alternative method for monitoring. BT-α marker was positive for 30% of the samples and positively correlated with enterococci (r = 0·61 and r = 0·64 for culture and qPCR methods respectively, P < 0·01). Rainfall had a moderate positive correlation with all faecal/MST indicators suggesting combined sewer overflows also severely impacted estuarine water quality. The high FIB and BT-α concentrations at upper estuary suggested that faecal pollution mainly originated from the peri-urban settlements around two creeks entering the estuary.

Abstract
Context Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer due to its high fibrotic content; it can affect the blood flow resistance. Objective To introduce duplex Doppler ultrasonography (DDUS) parameters of papillary thyroid carcinoma (PTC) and their correlation with size. Design The study was designed as a prospective study. Subjects and Methods Thyroid nodules of the patients who were already scheduled for thyroid surgery either for malignant thyroid nodules or multinodular goiter were evaluated for DDUS parameters. Size, systolic to diastolic flow velocity (S/D) ratio, pulsatility index (PI), and resistive index (RI) of each nodule were recorded. Nodules were diagnosed as PTC or benign nodules based on histopathology. DDUS parameters were compared between PTCs versus benign nodules and micro PTCs (≤ 10 mm) versus large PTCs (> 10 mm). A correlation analysis was performed between the size and DDUS parameters. Results 140 thyroid nodules (30 PTCs, 110 benign nodules) were obtained. The mean S/D ratio, PI, and RI values were significantly higher in PTC than in benign nodules (p values were 0.0001, 0.0003, and 0.0001 respectively). The optimal cut-off values of S/D (0.732), PI (0.732), and RI (0.738) had accuracy rates of 71%, 69%, and 69%, respectively. There was no statistically significant difference between micro PTC and large PTC with regards to DDUS parameters. The size and DDUS parameters of PTC showed no significant correlation. Conclusions PTC has a high resistive flow pattern regardless of its size; however the clinical utility of DDUS to differentiate a PTC from benign nodule is limited.

Abstract
Abstract
In this study, we determine the self attenuation correction factor for lichen samples collected from Erzurum, a city located in the eastern region of Turkey by using gamma-ray spectrometry. The self attenuation correction factor is calculated for 17 lichen samples with densities ranging from 0.683 g/cm3 to 0.886 g/cm3. The transmission method has been used to obtain self-attenuation correction factors. Self attenuation correction factor versus energy fit curve is presented. It is observed that self attenuation correction factor changes with density. At lower energies the self-attenuation correction factor has higher values. At higher energies it has smaller values and tends to become stable.

Abstract
Medicinal plants are increasingly being projected as suitable alternative source for the treatment of various diseases. However, toxic effects resulting from therapeutic bismuth compounds are still documented in animals and humans. This study described the genetic effects of five common lichen species and compared their activities on the genotoxicity induced by the colloidal bismuth subcitrate. After the application of colloidal bismuth subcitrate and lichen extracts, separate and together, human whole blood cultures were assessed by sister-chromatid exchange (SCE) and micronucleus tests. According to our results, the frequencies of SCE and micronucleus rate in peripheral lymphocytes were significantly increased by colloidal bismuth subcitrate (at dose 5 μg/mL) compared with controls. However, lichen extracts had no genotoxic effect. The order of anti-genotoxicity efficacy against colloidal bismuth subcitrate was Pseudevernia furfuracea, Dermotocarpon intestiniforme, Ramalina capitata, Parmelia pulla, respectively. However, Rhizoplaca melanophthalma did not show any effect against colloidal bismuth subcitrate genotoxicity. Present findings showed that the protective roles of lichens studied were dose related. In conclusion, this is the first study report describing the therapeutic potential of lichens against drug genotoxicity in human blood.

Abstract
It is known that lichens are utilized for the treatment of many diseases including ulcer, diabetes, and cancer for many years. Secondary metabolites in the structure of the lichens provide various activity properties for them. In the present study, cytotoxic and oxidative effects of main constituents of Pseudevernia furfuracea (L.) Zopf (Parmeliaceae), olivetoric acid (OA), and physodic acid (PA) were investigated on cultured human amnion fibroblasts (HAFs). OA and PA were isolated from P. furfuracea using column chromatography and their structures were determined by proton nuclear magnetic resonance and carbon-13 nuclear magnetic resonance. HAFs were incubated during 48 h in the presence of OA and PA, at different concentrations from 6.25 mg/L to 200 mg/L. OA showed higher cytotoxicity than PA. In fact, median inhibitory concentration values of OA and PA were 571.27 and 3373.69 mg/L, respectively. The lower concentrations (<50 mg/L) of OA and PA did not cause oxidative stress and genotoxicity; furthermore, they supported anti-oxidative capacity of HAFs. Therefore, all these data suggested that both tested metabolites, especially PA might be developed as natural health medicine to protect human body against oxidative stress and genotoxicity. As far as we know, this is the first report on the cytotoxic and anti-oxidative activities of OA and PA on HAFs.

Abstract
OBJECTIVE To demonstrate the utility of (18)F-FDG PET/CT in the differentiation of benign and malignant solitary fibrous tumors of the pleura (SFTP). MATERIALS AND METHODS A retrospective review was performed on the (18)F-FDG PET/CT data from 17 patients with histopathologically diagnosed benign or malignant SFTP. The size, side of SFTP, presence of necrosis, calcification, pleural effusion, hilar lymphadenopathy (LAP), density on CT images (Hounsfield unit-HU), and (18)F-FDG uptake (SUVmax) were recorded and compared in order to detect malignant SFTP. Statistical significance was set as p<0.05. RESULTS The difference in size, presence of necrosis, and hilar LAP on CT images were statistically significant (p=0.004, p<0.001, p=0.015, respectively) in a comparison of benign and malignant SFTPs. The mean HU of benign SFTP was 46.16±5.52HU, and for malignant SFTP it was 35.03±4.61HU (p=0.003). The mean SUVmax was 3.02±1.02 for benign SFTP and 4.89±2.12 for malignant SFTP (p=0.021). A cut-off value of ≥7cm for size, ≤39.81HU for density, and ≥3.47 for SUVmax was obtained by ROC analysis for detecting malignant SFTP. CONCLUSIONS (18)F-FDG PET/CT may have a limited role in diagnosing malignant SFTP in suspected patients.

Abstract
Abdominal cocoon is a rare disease characterized by a thick fibrous membrane surrounding and compressing the small intestines completely or partially, which results in mechanical small bowel obstruction. The clinical findings of the disease include recurrent ileus and subileus episodes, colicky abdominal pain, weight loss, and abdominal distension. The etiology and pathogenesis of abdominal cocoon is not clearly defined. Detection of the disease is essential for accurate treatment. Imaging modalities come into prominence due to the nonspecific clinical findings of the disease.

Abstract
Molybdenum cofactor deficiency (MoCD) is a rare autosomal recessive disorder that may present during the neonatal period with intractable seizures. Co-existence of MoCD and pyloric stenosis is previously reported as a coincidence or common etiology. The etiology of the two conditions is unclear; however, reports demonstrate neuronal deficiency in both. We report a neonate who was diagnosed with MoCD and hypertrophic pyloric stenosis.

Abstract
Imazalil (IMA), a commonly used fungicide in both agricultural and clinical domains, is suspected to produce serious toxic effects in vertebrates. In recent years, a number of studies have suggested that lichens might be easily accessible sources of natural drugs that could be used as a possible food supplement. Extensive research is being performed to explore the importance of lichen species, which are known to contain a variety of pharmacological active compounds. In this context, the antigenotoxic effect of aqueous Dermatocarpon intestiniforme (Körber) Hasse. extract (DIE) was studied against the genotoxic damage induced by IMA on cultured human lymphocytes (n = 6) using chromosomal aberration (CA) and micronucleus (MN) as cytogenetic endpoints. Human peripheral lymphocytes were treated in vitro with varying concentrations of DIE (0, 25, 50 and 100 μg/ml), tested in combination with IMA (336 μg/ml). DIE alone were not genotoxic and when combined with IMA treatment, it reduced the frequency of CAs and the rate of MNs. A clear dose-dependent decrease in the genotoxic damage of IMA was observed, suggesting a genoprotective role of DIE. The results of the present study suggest that this plant extract per se does not have a genotoxic potential, but can alleviate the genotoxicity of IMA on cultured human lymphocytes. In conclusion our findings may have an important application for the protection of cultured human lymphocyte from the genetic damage and side effects induced by medical and agricultural chemicals hazardous for people.

Abstract
AIM Antioxidative effect of nimodipine was investigated in patient with severe head trauma. METHODS The patients in group A were treated according to the standard procedures without nimodipine. Other patients in group B were treated with standard procedures plus intravenous nimodipine for a week. Three times per day, blood samples were taken from internal jugular venous saturation probe and central venous catheter for a week. The levels of malondialdehyde (MDA), reduced glutathione (GSH), nitrite, and nitrate, ascorbic acid, retinol and β-carotene in the serum were measured. RESULTS MDA levels in group B were significantly lower than those in the group A (P<0.05). As for GSH levels, it was observed that there was a significant increase in GSH levels in group B when compared to those in group A (P<0.01). Comparison of nitrate and nitrite levels in the serum of patient groups showed that these parameters were significantly higher in group B than those in group A (P<0.01). It was seen that there were a significant increase in ascorbic acid (P<0.01) and β-carotene (P<0.05) levels in group B when compared to those in group A. Values of retinol levels were slightly higher in group B than that of group A, and there was no significant difference between the groups. CONCLUSION Severe head trauma may increase oxidative stress. Administration of nimodipine may prevent the oxidative stress and may augment endogenous antioxidative defense systems in patients with severe head trauma.

Abstract
All the methanol extracts did not show mutagenic activity in Ames/Salmonella and Z. mays MI test systems. Furthermore, some extracts showed significant antimutagenic activity against 9-AA in Ames test system. Inhibition rates for 9-AA mutagenicity ranged from 25.51% (P. furfuracea - 0.05 microg/plate) to 66.14% (C. islandica - 0.05 microg/plate). In addition, all of the extracts showed significant antimutagenic activity against sodium azide (NaN3) mutagenicity on MI values of Z. mays.

Abstract
The assessment of tumor vascularization by color flow Doppler sonography (CFDS) has been suggested for the distinction between benign and malignant thyroid nodules. Our objective was to investigate if the CFDS results reflect the percentage of histologically determined microvessels in adenomas (As), adenomatous nodules (ANs), and papillary carcinomas (PCs). Tissue sections from 10 adenomas, 8 ANs and 13 PC and surrounding tissue of 10 PCs and 2 benign nodules were immunostained for CD34. A computerized image analysis was used to determine the microvessel density in four hot spots and ten systematically selected fields. Preoperatively CFDS was performed and classified according to Frates et al. We found a consistent percentage increase of CD34 stained microvessels in PCs (83 and 96%) as compared to adenomas and ANs (38 and 49%) determined by the hot spot analysis and systematic field analysis. A ROC analysis on the basis of the histologically determined number of microvessels demonstrated 70% microvessels as an optimal cut point for the diagnosis of PC with the highest sensitivity of 92% and highest specificity of 89%. The analysis of the CFDS-classification IV for the distinction between PCs and adenomas and ANs showed a sensitivity of 62% with a specificity of 100%. The lower sensitivity of the CFDS classification as compared with the immunohistologic determination of the microvessel density indicates that the CFDS classification detects the pathognomonic intranodular microvessels only incompletely. The higher CFDS specificity is most likely due to the detection of other vascular aspects of malignancy in addition to intranodular microvessels.

Abstract
The objective of this study was to investigate the association between mortality and inflammation in patients who were admitted to the emergency room with gastrointestinal bleeding. Patients (n = 96) managed at two medical centres were included in the study. Initial levels of serum C-reactive protein (CRP), haemoglobin and albumin, and leucocyte and thrombocyte counts for 28 patients who died were compared with those for the 68 patients who survived and were successfully discharged. The data were analysed using the chi(2)-test. Serum levels of CRP and leucocyte counts were significantly higher, and albumin and haemoglobin were significantly lower in patients who died compared with patients who survived. The increased levels of serum CRP and leucocyte counts, and decreased levels of albumin and haemoglobin were found to be independent risk factors for mortality. It is concluded that increased serum CRP levels and leucocyte counts combined with decreased albumin and haemoglobin levels on admission to the emergency room may be used as predictive factors of mortality in patients with gastrointestinal bleeding.

Abstract
AIM Aim of the study was to test the safety and efficacy of sutureless colorectal anastomosis using bipolar coagulation. MATERIAL AND METHODS Thirty-six Wistar albino rats were used. The rectum just proximal to the peritoneal reflection was transected in 22 rats (Group 1), and the bowel ends were anastomosed or welded end-to-end using bipolar coagulating forceps (Scoville-Greenwood, 60-1765-001, ConMed, USA). Coagulation using 60 milliamperes took one second for each weld. In 14 rats (Group 2), bowel anastomosis was carried out by hand-sewn sutures. The animals were followed up for general condition and body weight, and were sacrificed at six weeks. The anastomoses were studied with regard to burst pressure, stenosis and histopathology. RESULTS All rats survived, and body weight gain was significant (p<0.01 for Group 1, p<0.05 for Group 2). There were no intraabdominal complications (leakage, obstruction, etc.), except in one rat (in Group 2), who had intraabdominal abscess. Although intraluminal pressure was increased to 40 cm H2O with extensive stretching of the colorectal segment, the anastomoses did not burst or open in either the sutureless or sutured groups. The bowel diameter 1 cm distal and 1 cm proximal to the anastomoses did not show any difference between both groups. Neomucosa completely covered 78% of sutured anastomoses and 36% of sutureless anastomoses (p<0.05). Inflammation developed in 78% of sutured anastomoses and 36% of sutureless anastomoses (p<0.05). Edema, giant cell and mast cell infiltration were equivalent in both anastomoses. Lymphoid tissue hyperplasia markedly appeared in the sutureless anastomoses (p<0.01). CONCLUSION This simple technique of sutureless colorectal anastomosis may be useful and offer an alternative to other colorectal anastomosis techniques.

Abstract
Orbital lymphangioma is an uncommon, benign cystic lesion, generally manifest in childhood. It usually presents with a slowly progressive proptosis, displacement of the globe, ptosis and restriction of eye movements. Occasionally, focal lesions may remain asymptomatic. Spontaneous intraorbital haemorrhage may cause acute proptosis, compressive optic neuropathy and loss of vision. An 8-year-old girl presented with progressive left proptosis and a unilateral soft tissue mass at the supraorbital frontal region. Multiple intracranial venous angiomas were seen on MRI. Surgical decompression of the optic nerve was performed because of progressive decrease in visual acuity. We review the relevant literature; rarity of the orbital lymphangioma and its association with non-contiguous intracranial vascular anomalies were emphasized.

Abstract
AIM How obstructive jaundice causes the intestinal barrier to be injured is still controversially discussed. In this study, we hypothesize that intestinal prostaglandin E (2), a cytoprotective factor, may be affected by the bile duct obstruction. MATERIALS AND METHODS Four groups of Wistar-Albino rats were used: in Groups 1 and 3, the rats underwent a sham operation. In Groups 2 and 4, the common bile duct was doubly ligated. Relaparotomy was performed after one week in Groups 1 and 2, and after two weeks in Groups 3 and 4, and specimens of the jejunum, ileum and liver were obtained for intestinal PGE (2) analysis and histopathological evaluation. RESULTS Jejunal and ileal PGE (2) levels had significantly decreased in two-week bile duct-ligated rats compared to one-week ligated rats and the sham group (p < 0.01). Tissue injury scores (Chiu score) of the ileum were significantly higher in the two-week and one-week ligated rats than in the controls (p < 0.01 and p < 0.05, respectively). The jejunal injury score was significantly higher in the two-week ligated rats compared to controls (p < 0.05). The ileal and jejunal injury scores were higher in the two-week ligated rats than in the one-week ligated rats (p < 0.01 and p < 0.05, respectively). Precirrhotic fibrosis was detected in all two-week ligated rats, but in only 7 of 10 one-week ligated rats. CONCLUSIONS Obstructive jaundice associated with intestinal tissue injury and precirrhotic changes leads to reduced intestinal PGE (2)-levels, suggesting an adverse effect on the intestinal cytoprotective process.
