Abstract
Diagnostic, prognostic, and therapeutic procedures for patients with prolonged disorders of consciousness (pDoCs) vary significantly across countries and clinical settings, likely due to organizational factors (e.g., research vs. non-academic hospitals), expertise and availability of resources (e.g., financial and human). Two international guidelines, one from the European Academy of Neurology (EAN) and one from the American Academy of Neurology (AAN) in collaboration with the American Congress of Rehabilitation Medicine (ACRM) and the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR), were developed to facilitate consistent practice among professionals working with this challenging patient population. While the recommendations of both guidelines agree in principle, it remains an open issue how to implement them into clinical practice in the care pathway for patients with pDoCs. We conducted an online survey to explore health professional clinical practices related to the management of patients with pDoCs, and compare said practices with selected recommendations from both the guidelines. The survey revealed that while some recommendations are being followed, others are not and/or may require more honing/specificity to enhance their clinical utility. Particular attention should be given to the implementation of a multimodal assessment of residual consciousness, to the detection and treatment of pain, and to the impact of restrictions imposed by COVID-19 pandemics on the involvement of patients' families/representatives.

Abstract
BACKGROUND AND OBJECTIVES Comprehensive guidelines for the diagnosis, prognosis, and treatment of disorders of consciousness (DoC) in pediatric patients have not yet been released. We aimed to summarize available evidence for DoC with >14 days duration to support the future development of guidelines for children, adolescents and young adults aged 6 months-18 years. METHODS This scoping review was reported based on Preferred Reporting Items for Systematic reviews and Meta-Analyses-extension for Scoping Reviews guidelines. A systematic search identified records from 4 databases: PubMed, Embase, Cochrane Library, and Web of Science. Abstracts received 3 blind reviews. Corresponding full-text articles rated as "in-scope" and reporting data not published in any other retained article (i.e., no double reporting) were identified and assigned to 5 thematic evaluating teams. Full-text articles were reviewed using a double-blind standardized form. Level of evidence was graded, and summative statements were generated. RESULTS On November 9, 2022, 2,167 documents had been identified; 132 articles were retained, of which 33 (25%) were published over the past 5 years. Overall, 2,161 individuals met the inclusion criteria; female patients were 527 of 1,554 (33.9%) cases included, whose sex was identifiable. Of 132 articles, 57 (43.2%) were single case reports and only 5 (3.8%) clinical trials; the level of evidence was prevalently low (80/132; 60.6%). Most studies included neurobehavioral measures (84/127; 66.1%) and neuroimaging (81/127; 63.8%); 59 (46.5%) were mainly related to diagnosis, 56 (44.1%) to prognosis, and 44 (34.6%) to treatment. Most frequently used neurobehavioral tools included the Coma Recovery Scale-Revised, Coma/Near-Coma Scale, Level of Cognitive Functioning Assessment Scale, and Post-Acute Level of Consciousness scale. EEG, event-related potentials, structural CT, and MRI were the most frequently used instrumental techniques. In 29/53 (54.7%) cases, DoC improvement was observed, which was associated with treatment with amantadine. DISCUSSION The literature on pediatric DoCs is mainly observational, and clinical details are either inconsistently presented or absent. Conclusions drawn from many studies convey insubstantial evidence and have limited validity and low potential for translation in clinical practice. Despite these limitations, our work summarizes the extant literature and constitutes a base for future guidelines related to the diagnosis, prognosis, and treatment of pediatric DoC.

Abstract
Confirmation of the exact voluntary movements of patients with disorder of consciousness following severe traumatic brain injury (TBI) is difficult because of the associated communication disturbances. In this pilot study, we investigated whether regional brain glucose metabolism assessed by 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET) at rest could predict voluntary movement in severe TBI patients, particularly those with sufficient upper limb capacity to use communication devices. We visually and verbally instructed patients to clasp or open their hands. After video capture, three independent rehabilitation therapists determined whether the patients' movements were voluntary or involuntary. The results were compared with the standardized uptake value in the primary motor cortex, referring to the Penfield's homunculus, by resting state by FDG-PET imaged 1 year prior. Results showed that glucose uptake in the left (p = 0.0015) and right (p = 0.0121) proximal limb of the primary motor cortex, based on Penfield's homunculus on cerebral cartography, may reflect contralateral voluntary movement. Receiver operating characteristic curve analysis showed that a mean cutoff standardized uptake value of 5.47 ± 0.08 provided the best sensitivity and specificity for differentiating between voluntary and involuntary movements in each area. FDG-PET may be a useful and robust biomarker for predicting long-term recovery of motor function in severe TBI patients with disorders of consciousness.

Abstract
Abstract
Positron emission tomography (PET) is useful to detect malignant tumors by imaging glucose or amino acid metabolism. Whole-body PET with the detector arrangement in a large diameter is currently used for brain imaging, however, the detector arrangement in small diameter is better for brain imaging. Stereotactic radiosurgery (SRS) treats brain tumor with maintaining cognitive function. Therefore, it needs more dedicated PET to identify small lesions and their localization. Then, we developed the world's first brain-dedicated PET with detectors arranged in a hemisphere of 28 cm diameter, attaining 2.2 mm in spatial resolution. This development was performed with ATOX CO., LTD and the brain-dedicated PET has been commercialized as VrainTM. Ten normal volunteers (22 - 45 age male) underwent 18FDG-PET using a whole-body PET (Discovery MI, GE) and the brain-PET for 10-min each, which were started 30-min and 45-min after FDG injection, respectively. A phantom with 10-22 diameter hot spheres and background (radioactivity ratio, 4:1) was also acquired by both PET systems, then estimated the radioactivity ratio in case of 2-mm diameter hot sphere. As a results, the inferior colliculus, substantia nigra, red nucleus, and brain stem raphe nucleus were identified with the brain-PET. The inferior colliculus was identified with the whole-body PET, but other nuclei were not. Based on phantom study, it was estimated that radioactivity in a 2-mm diameter sphere was measured with 1.4 - 2.9 times higher contrast than whole-body PET. The substantia nigra and the red nucleus has 5.0-6.0mm in short diameter on MRI T2WI axial image. The raphe nucleus extends laterally to 2.5mm on postmortem brain specimens. We concluded that our brain-dedicated PET can identify approximately 2.5mm diameter tumor clearly and will be particularly useful in SRS.

Abstract
Abstract
Background
The biological effects of low-dose radiation from cardiac imaging or intervention remain largely unknown. This study aimed to evaluate the effects of ionized radiation from cardiac catheterization on genomic DNA integrity and inflammatory cytokines in patients and operators.
Methods
Peripheral mononuclear cells (MNCs) were isolated from patients (n=52) and operators (n=35) before and after coronary angiography and/or percutaneous coronary intervention. Expression of gammaH2AX, a marker for DNA double-strand breaks, was measured by immunofluorescence. Dicentric chromosomes (DICs), a form of chromosome aberrations, were assayed using a fluorescent in situ hybridization technique.
Results
In the patient MNCs, the numbers of gammaH2AX foci and DICs increased after cardiac catheterization by 101±75% and 28±99%, respectively (P<0.05 for both). The mRNA expressions of interleukin (IL)-1α, IL-1β, leukemia inhibitory factor (LIF) and caspase-1 were significantly increased by radiation exposure from cardiac catheterization. The increase in IL-1β was significantly correlated with that of gammaH2AX, but not with dose area product. In the operators, neither gammaH2AX foci nor DICs level was changed, but IL-1β mRNA was significantly increased. Protein expression of IkappaBα was significantly decreased in both groups.
Conclusions
DNA damage was increased in the MNCs of patients, but not of operators, who underwent cardiac catheterization. Inflammatory cytokines were increased both in the patients and operators, presumably through activation of NF-kappaB. Further efforts to reduce radiation exposure from cardiac catheterization are necessary both for patients and operators.

Abstract
Sialorrhea is a major cause of recurrent aspiration pneumonia in severe chronic brain injury. Previous reports have shown that transdermal scopolamine can decrease saliva production. We present four patients with severe chronic brain injury who experienced repeat aspiration pneumonia with sialorrhea. Longitudinal computed tomography examinations to assess the therapeutic effect were performed in all four cases before and after transdermal scopolamine. Transdermal scopolamine was applied as a patch (0.1 g/2.5 cm2) behind the earlobe every 24 h after confirming the absence of glaucoma. Patches were formulated as an in-hospital preparation (scopolamine butylbromide 0.25 g and hydrophilic cream 4.75 g) under the approval of our institutional review board. Longitudinal computed tomography after transdermal scopolamine use showed a decrease in pleural effusions associated with continuous aspiration pneumonia in all four cases. The data from repeat computed tomography suggest that long-term transdermal scopolamine for reducing saliva production may be a reasonable option for appropriate palliative care in severe chronic brain injury patients.

Abstract
Purpose Mid- to long-term outcome in glioblastoma (GBM) patients following supratotal resection (SupTR), involving complete resection both of contrast-enhancing enhanced (CE) tumors and areas of methionine (Met) uptake on 11C-Met positron emission tomography (Met-PET), are not clarified. Methods A retrospective, single-center review was performed in newly diagnosed, IDH1 wild-type GBM patients, comparing SupTR with gross total resection (GTR), in which only CE tumor tissue was completely resected. Only patients who were operated on until November 2019 were included for evaluation of mid- to long-term outcome. Following resection, all patients underwent standard radiotherapy and temozolomide treatment, and were followed for progression-free survival (PFS) and overall survival (OS). Results Among the 30 patients included in this study, 7 underwent SupTR and 23 underwent GTR. Awake craniotomy with cortical and subcortical mapping was more frequently performed in the SupTR group than in the GTR group. During the follow-up period, significantly different patterns of disease progression were observed between groups. Although more than 80% of recurrences were local in the GTR group, all recurrences in the SupTR group were distant. Median PFS in the GTR and SupTR groups was 8.8 months (95% confidence interval [CI], 5.2–14.9) and 27.8 months (95% CI, 6.0-not estimable) respectively (p=0.08 by log-rank test). Median OS was 17.7 months (95% CI, 14.2–35.1) in GTR and not reached (95% CI, 30.5-not estimable) in SupTR, respectively; this difference was statistically significant (p=0.03 by log-rank test). No postoperative neurocognitive impairment was observed in SupTR patients. Conclusion Compared to GTR alone, SupTR strategy with aggressive resection of both CE tumors and Met uptake area in GBM patients under awake craniotomy with functional preservation results in a survival benefit associated with better local control.

Abstract
Abstract
Background
Around 10% of patients with acute myocardial infarction (AMI) have chronic total occlusion (CTO) in non-infarct-related vessels, and they are known to be associated with higher mortality in acute phase. However, its impact on long-term prognosis after discharge remains unclear.
Purpose
The purpose of this study was to investigate the influence of presenting CTO lesion on long-term prognosis in patients with AMI.
Method
Consecutive 552 patients with AMI (male 78.3%, age 68±13 years), who had been discharged alive from our hospital, were analyzed. We divided the patients into two groups based on whether they had CTO lesion in a non-infarct-related artery or not: CTO + (n=49) and CTO - (n=503).
Results
Kaplan-Meier analysis (mean follow-up 1,424 days) revealed that all-cause mortality was significantly higher in CTO + group than in CTO - group (Figure, P<0.001). Cox hazard ratio was 2.740, indicating a higher risk of all-cause death in the CTO + group (95% CI 1.606–4.651, P<0.001).
Conclusion
Concurrent coronary CTO lesions in non-culprit arteries were associated with increased long-term mortality in patients with AMI.

Abstract
Abstract
Background
Soluble guanyl cyclase (sGC) is a receptor for nitric oxide (NO) and plays an important role in vascular tonus. sGC stimulant is a therapeutic agent for pulmonary hypertension and an advantage of sGC stimulant over phosphodiesterase (PDE)-5 inhibitors is that sGC stimulant exerts its effect even when NO production is reduced. NO derived from vascular endothelial cells is immediately absorbed by hemoglobin (Hb), which leads to the production of methemoglobin (Met-Hb) when oxidized. Previous report has shown that the therapeutic effect of PDE-5 inhibitors was associated with levels of Met-Hb.
Purpose
In this study, we examined the relationship between the effect of riociguat and levels of Met-Hb in patients with chronic thromboembolic pulmonary hypertension (CTEPH).
Methods
The study population comprised 18 patients with CTEPH. Mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were assessed before and after administration of riociguat, and changes in mPAP and PVR were defined as ΔmPAP and ΔPVR, respectively. Since the level of Met-Hb was obtained as the percentage of Hb (FMet-Hb), the amount of Met-Hb was calculated by following formula:
Met-Hb (mg/dL) = Hb (g/dL) × FMet-Hb (%) × 10.
Results
The amount of Met-Hb value before administration of riociguat was significantly correlated with the degree of improvement in mPAP and PVR after administration of riocigat (R=−0.502, P<0.05 mPAP; R=−0.481, P<0.05 PVR, respectively) as shown in figures.
Conclusion
Our findings suggest that the level of Met-Hb before treatment may predict the therapeutic effect of sGC stimulants in patients with CTEPH.

Abstract
OBJECTIVE Olfactory dysfunction is often observed after severe traumatic brain injury (sTBI). Its diagnosis is difficult because patients with sTBI have a communication disability following impaired consciousness and communication disorder. The intravenous thiamine injection (IT) test is one of the representative diagnostic examinations to identify dysfunction, and it is often used in medical certification for liability insurance of automobiles in Japan because it could be judged by a simple reaction. However, the extent of usefulness of the IT test in the diagnosis of olfactory dysfunction in patients with sTBI is unknown. In this study, we validated the usability of the IT test and compared the results with those of the odor stick identification test for the Japanese (OSIT-J) to evaluate the sensitivity of the IT test in patients with sTBI. METHODS The study enrolled 205 subjects, including 10 healthy volunteers and 195 patients with sTBI. First, we examined olfactory dysfunction in sTBI patients using OSIT-J. Subsequently, we performed the IT test among patients with olfactory dysfunction. RESULTS In the first part, 41 subjects, including 10 healthy volunteers, were examined by using the OSIT-J test. As a result, 28 patients were diagnosed with olfactory dysfunction (90.3%, p<0.0001), including anosmia and parosmia, compared with healthy volunteers. Among the 12 odors, garlic odor was easily recognized for patients with olfactory dysfunction. As a consequence of the IT test for 11 patients with olfactory dysfunction, four patients recognized thiamine odor, and seven patients did not. All four patients could recognize the garlic odor of OSIT-J, but 2 of the seven patients could recognize the garlic odor of OSIT-J, suggesting that the thiamine odor is linked to garlic odor (p=0.046), but not always. The detection rate of olfactory dysfunction through the IT test was 36.4%. CONCLUSION Our data showed that garlic odor, which is similar to thiamine odor, was easily recognizable for patients with sTBI. However, the IT test might overlook the diagnosis of olfactory dysfunction because it only identifies one odor. In addition, thiamine frequently induces angialgia. We should pay attention to the overconfidence of the IT test for patients with sTBI.

Abstract
Patients with severe traumatic brain injury (sTBI) have difficulty knowing whether they are accurately expressing their thoughts and emotions because of disorders of consciousness, disrupted higher brain function, and verbal disturbances. As a consequence of an insufficient ability to communicate, objective evaluations are needed from family members, medical staff, and caregivers. One such evaluation is the assessment of functioning brain areas. Recently, multimodal brain imaging has been used to explore the function of damaged brain areas. [18F]-fluorodeoxyglucose positron emission tomography-computed tomography ([18F]FDG-PET/CT) is a successful tool for examining brain function. However, the assessment of brain glucose metabolism based on [18F]FDG-PET/CT is not standardized and depends on several varying parameters, as well as the patient's condition. Here, we describe a series of semiquantitative assessment protocols for a region-of-interest (ROI) image analysis using self-produced [18F]FDG tracers in patients with sTBI. The protocol focuses on screening the participants, preparing the [18F]FDG tracer in the hot lab, scheduling the acquisition of [18F]FDG-PET/CT brain images, and measuring glucose metabolism using the ROI analysis from a targeted brain area.

Abstract
Little is known about changes in glucose metabolism in patients with chronic severe traumatic brain injury (sTBI). It remains to be elucidated how neurological manifestations of sTBI are associated with brain glucose metabolism during longitudinal follow-up. We show here that neurological manifestations are associated with changes of brain glucose metabolism by using two serial 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) images. In this longitudinal observational study, two serial 18F-FDG PET/CT images from each of 45 patients were analyzed for whole-brain maximum standardized uptake values (SUVmax). For clinical assessment, we applied two different scales: the coma recovery scale-revised and the original Chiba score with additional information regarding nutrition, excretion, facial expression, and position change of the patient's relative immobility and bedridden state. As a result, the increased FDG uptake group was associated with a high level of wakefulness (first PET, p = 0.04; second PET, p = 0.01) and small ventricular size (first PET, p = 0.01; second PET, p = 0.01). In addition, anticonvulsant withdrawal (p = 0.001), improvement of total Chiba score (p = 0.01), language expression (p = 0.03), position change (p = 0.03), and communication (p = 0.03) were accelerated in the increased FDG uptake group. Spearman's rank correlation coefficients of change in SUVmax and language expression between the first and second PET were 0.4 (p = 0.01). Our results indicate that chronic severe traumatic head injury patients have changed brain glucose metabolism.

Abstract
A considerable portion of agricultural land in central-east Japan has been contaminated by radioactive material, particularly radioactive Cs, due to the industrial accident at the Fukushima Daiichi nuclear power plant. Understanding the mechanism of absorption, translocation and accumulation of Cs+ in plants will greatly assist in developing approaches to help reduce the radioactive contamination of agricultural products. At present, however, little is known regarding the Cs+ transporters in rice. A transporter-enriched yeast expression library was constructed and the library was screened for Cs+ transporter genes. The 1452 full length cDNAs encoding transporter genes were obtained from the Rice Genome Resource Center and 1358 clones of these transporter genes were successively subcloned into yeast expression vectors; which were then transferred into yeast. Using this library, both positive and negative selection screens can be performed, which have not been previously possible. The constructed library is an excellent tool for the isolation of novel transporter genes. This library was screened for clones that were sensitive to Cs+ using a SD-Gal medium containing either 30 or 70 mM CsCl; resulting in the isolation of 13 Cs+ sensitive clones. 137 Cs absorption experiments were conducted and confirmed that all of the identified clones were able to absorb 137 Cs. A total of 3 potassium transporters, 2 ABC transporters and 1 NRAMP transporter were among the 13 identified clones.

Abstract
Cell populations with differing proliferative, stem-like and tumorigenic states co-exist in most tumors and especially malignant gliomas. Whether metabolic variations can drive this heterogeneity by controlling dynamic changes in cell states is unknown. Metabolite profiling of human adult glioblastoma stem-like cells upon loss of their tumorigenicity revealed a switch in the catabolism of the GABA neurotransmitter toward enhanced production and secretion of its by-product GHB (4-hydroxybutyrate). This switch was driven by succinic semialdehyde dehydrogenase (SSADH) downregulation. Enhancing GHB levels via SSADH downregulation or GHB supplementation triggered cell conversion into a less aggressive phenotypic state. GHB affected adult glioblastoma cells with varying molecular profiles, along with cells from pediatric pontine gliomas. In all cell types, GHB acted by inhibiting α-ketoglutarate-dependent Ten–eleven Translocations (TET) activity, resulting in decreased levels of the 5-hydroxymethylcytosine epigenetic mark. In patients, low SSADH expression was correlated with high GHB/α-ketoglutarate ratios, and distinguished weakly proliferative/differentiated glioblastoma territories from proliferative/non-differentiated territories. Our findings support an active participation of metabolic variations in the genesis of tumor heterogeneity.

Abstract
Purpose: To compare a new vessel-sparing technique combining valvuloplasty with axial transposition of a competent tributary vein versus single valvuloplasty for the treatment of greater saphenous vein (GSV) incompetence. Methods: In 55 patients with GSV incompetence, 29 of 57 limbs were treated by angioscopic valvuloplasty of the subterminal valve alone, whereas the remaining 28 limbs underwent angioscopic valvuloplasty combined with axial transposition of a competent tributary vein identified preoperatively by duplex scanning. After angioscopic valvuloplasty in the latter group, the competent tributary vein was exposed and cut 1.5 cm distal to its insertion point on the GSV. The transected vein was anastomosed end to side to the GSV, which was ligated between the tributary insertion site and the anastomosis. Changes in venous hemodynamics, including venous filling index (VFI), ejection fraction (EF), and residual volume fraction (RVF), were analyzed by use of air plethysmography. Results: In the 1-year follow-up, no venous thrombosis was detected in either group. In the valvuloplasty-only group, 22 (75.9%) limbs exhibited reflux in the proximal GSV; recurrent varicose veins were detected in 5 (17.2%) limbs. In contrast, only 2 (7.1%) limbs showed reflux in the valvuloplasty + transposition group. There were no significant differences in EF and RVF between the groups before or after the operation, although a significant difference was seen in VFI at 1 year (p = 0.005, Wilcoxon rank sum test). Conclusions: Valvuloplasty combined with tributary vein transposition gives a better result than valvuloplasty alone at 1 year. This new treatment option may be useful for both reducing the rate of varicose veins and sparing the GSV for grafting.

Abstract
Objective: To compare different duplex-and air plethysmography (APG)-derived parameters between patients with relatively early and those with advanced chronic venous insufficiency (CVI), and to investigate the indicative parameters reflecting the progression of CVI. Methods: Design: Prospective study at the University Hospital. Patients: In total 686 limbs in 574 patients at various clinical stages of CVI were included. The clinical manifestations were categorized according to the CEAP (clinical, aetiologic, anatomic and pathophysiologic) classification, and the patients were divided into two groups: group I (C1-3EP,SAS,D,PPR,O, relatively early stage of CVI) and group II (C4-6EP,SAS,D,PPR,O, advanced CVI). The distribution of venous insufficiency including the sapheno-femoral junction (SFJ), great saphenous vein (GSV), sapheno–popliteal junction (SPJ), common femoral vein (CFV), femoral vein (FV), popliteal vein (POPV), thigh perforators (TPV) and calf perforators (CPV) was determined by duplex ultrasound. The main duplex-derived parameters assessed were the reflux time (RT; s), peak reflux velocity (PRV; cm/s) and peak reflux flow (PRF; mL/s). The venous reflux was assumed to be present if the duration of reflux was ≥0.5 s. The data obtained by APG were on VV (mL), VFI (mL/s), EF (%) and RVF (%). Results: There was no significant difference in overall superficial venous reflux between the groups ( P=0.331). The frequency of deep and perforating vein incompetence differed only when superficial reflux was included in group II. The VFI and RVF were significantly higher in secondary CVI than in primary CVI ( P=0.0001, 0.003, respectively). In the secondary CVI, patients with reflux and obstruction showed significantly higher RVF than those with reflux alone ( P=0.003). The RT did not improve the discrimination power between the groups. In contrast, the PRV had significant discrimination power at the SFJ ( P<0.0001) and SPJ ( P=0.022), and in the GSV ( P<0.0001), the FV ( P=0.017), and the POPV ( P=0.0003). The PRF was significantly higher in group II at the SFJ ( P<0.0001), in the GSV ( P=0.002), in the CFV ( P=0.011), in the FV ( P=0.027), and the POPV ( P=0.016). Conclusions: This present study has suggested the importance of superficial venous insufficiency in the development of advanced CVI. In the secondary CVI, obstruction affects the RVF alone. The PRV and PRF are better parameters than the RT for discrimination of clinical severity in both superficial and deep venous insufficiency, and should be used to quantify venous valvular insufficiency.

Abstract
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.

Abstract
OBJECTIVE The aim of the study is to compare ultrasound-guided foam sclerotherapy (UGFS: injection of foam sclerosant under ultrasound guidance) of the great saphenous vein (GSV) combined with visual foam sclerotherapy (VFS: injection of foam sclerosant under visual control) for varicose tributary veins and VFS alone in the treatment of GSV reflux. DESIGN AND METHODS A total of 133 limbs in 97 patients with GSV reflux were randomised to receive either VFS alone or VFS combined with UGFS. In both groups, 1% polidocanol foam was used. Assessments included duplex ultrasonography, evaluation of Venous Clinical Severity Scores (VCSS) and CEAP (clinical, etiologic, anatomic, and pathophysiologic) scores. Ultrasonographic inspection of the foam in the GSV was carried out during 5 min before compression was applied. The primary 'end' point of the study was obliteration of the GSV at 6 months. RESULTS A total of 51 limbs in 48 patients were treated with UGFS + VFS and the remaining 52 limbs in 49 patients were treated with VFS alone. There were no significant inter-group differences in patient age, male: female ratio, height, weight, body mass index, CEAP clinical scores or VCSS. The GSV diameter was 6.0 ± 1.7 mm (median ± interquartile range) in the UGFS + VFS group and 5.7 ± 1.6 mm in the VFS group (p = 0.419). The mean injected volume of foam for varicose tributary veins was 4 ± 2 ml in the UGFS + VFS group and 6 ± 2 ml in the VFS group, a significantly higher amount of foam being used in the latter (p < 0.001). However, the mean total amount of foam was greater in limbs treated with UFGS + VFS than in those treated with VFS alone (p = 0.017). Ultrasonographic inspection revealed complete vasospasm of the GSV in 37 (72.5%) limbs in the UGFS + VFS group and 29 (55.8%) in the VFS group during sclerotherapy (p = 0.097). At 6-month follow-up, complete occlusion was found in 23 limbs (45.1%) treated with UGFS + VFS and in 22 limbs (42.3%) treated with VFS. The difference between the two groups was not significant (p = 0.775). Reflux was absent in 30 limbs (58.8%) treated with UGFS + VFS and in 37 (71.2%) treated with VFS (p = 0.190). There was no inter-group difference in post-treatment VCSS (p = 0.223). CONCLUSIONS These results show that UGFS + VFS and VFS are equally effective for the treatment of GSV reflux, despite the lower volume of foam used for VFS alone.

Abstract
The bleeding from various veins can be intense and may be mistaken for arterial haemorrhage. Several fatal cases are reported due to delay of treatment and inappropriate first aid. We describe five cases of haemorrhage from varicose veins that were treated with foam sclerotherapy. Polidocanol foam was injected in the various veins using ultrasound guidance. There was no recurrence of haemorrhage in any patient during the 17.4 months follow-up period. Foam sclerotherapy can be performed easily in an out-patient clinic setting. This method is an ideal therapy for haemorrhage from varicose veins because it mitigates problematic varicose veins.

Abstract
BACKGROUND The risk factors that affect the development of post-thrombotic syndrome (PTS) are not fully recognized, and it is difficult to reliably predict which patients are likely to develop PTS in acute phase of deep vein thrombosis (DVT). AIMS To investigate changes in calf muscle deoxygenated hemoglobin (HHb) levels after DVT, and to determine the indicative parameters reflecting the progression of PTS. METHODS Seventy-six consecutive patients with a first episode of unilateral DVT were prospectively enrolled. Clinical manifestations were categorized according to the CEAP (Clinical, Etiologic, Anatomical, and Pathophysiologic) classification, and the patients were divided into no-PTS (C(0-3)E(s),A(s,d,p),P(r,o)) and PTS (C(4-6)E(s),A(s,d,p),P(r,o)) groups. Near-infrared spectroscopy (NIRS) was used to measure calf muscle HHb levels at 6 months after diagnosis of DVT. The calf venous blood filling index (HHbFI) was calculated on standing, and the venous ejection index and the venous retention index (HHbRI) were then obtained after exercise. All patients were followed up for more than 24 months after the diagnosis of DVT. RESULTS Of 76 patients evaluated, 20 (26.3%) had PTS. The NIRS-derived HHbFI and HHbRI were significantly increased in patients who developed PTS in comparison with those who did not (P = 0.04 and P = 0.0001, respectively). HHbRI was significantly increased in patients with iliofemoral DVT in comparison with patients with calf DVT (P = 0.041). An optimal cut-off point of 2.9 for HHbRI showed the strongest ability to predict the development of PTS, with a sensitivity of 100% and a specificity of 82.1%. CONCLUSIONS HHbRI as measured by NIRS is significantly increased in patients with iliofemoral DVT as compared with those with calf DVT. Furthermore, HHbRI > 2.9 is a strong predictor of the development of PTS at 6 months.

Abstract
SUMMARY We report a case of bilateral ischial pressure sores complicated with urethral fistula, caused by previous complete ischiectomy. Successful reconstruction was achieved after closure of the bladder neck. The large defect in the bilateral ischium and perineum was covered simultaneously with a free total plantar flap. The paucity of suitable recipient vessels for microvascular anastomoses was resolved by the creation of an arteriovenous loop, when the closure of bladder neck was performed in a supine position.

Abstract
OBJECTIVE To evaluate the efficacy and haemodynamic effects of great saphenous vein (GSV) sparing surgery--valvuloplasty combined with axial transposition of a competent tributary vein (A-VACT). MATERIALS AND METHODS Eighty-five limbs in 74 patients with isolated GSV incompetence were selected for GSV sparing surgery. After angiographic valvuloplasty, the competent tributary vein was exposed and cut 1.5 cm distal to its insertion point on the GSV. The transected vein was anastomosed end-to-side to the GSV, which was ligated between the tributary insertion site and the anastomosis. Venous valve competence were screened by serial postoperative duplex examination, and venous haemodynamic changes were analyzed using venous filling index (VFI) measured by air plethysmograph pre- and postoperatively. The follow-up period was 5-years. RESULTS Sixty-seven patients were included in whom 76 limbs were treated. There was a statistically significant reduction in the vein diameter at the SFJ after 5-years (0.83 S.D. 0.29 cm to 0.46 S.D. 0.12 cm, p=0.0002, Wilcoxon). Similarly, significant reduction was found in the GSV at the 5-year follow-up point (0.63 S.D. 0.19 cm to 0.39 S.D. 0.11 cm, p<0.0001, Wilcoxon). On the other hand, there was significant increase in the diameter of the competent tributary vein postoperatively (0.22 S.D. 0.13 cm to 0.31 S.D. 0.12 cm, p<0.0001, Wilcoxon). Duplex scanning demonstrated reflux at the SFJ in 12 limbs (16%). Similarly, in the GSV, venous reflux was found in 13 limbs (17%). Reflux in the transposed tributary vein was found in 20 limbs (26%). But only 7 limbs (9%) had minor varicose veins' recurrence. VFI remained normal during the follow-up examination. The preoperative VFI confirmed the presence of venous reflux, but there were significant improvement in the VFI values at all postoperative examinations. CONCLUSIONS A-VACT procedure improves venous function, resolves varicose veins at 5-years follow-up as well as preserving the GSV for future grafting.

Abstract
OBJECTIVES To investigate the presence of lower limb deep vein thrombosis (DVT) and prognosis in patients with symptomatic pulmonary embolism (PE). MATERIALS AND METHODS A total of 203 consecutive referral patients with PE were included. The distribution of DVT was evaluated with compression ultrasound (CUS), and all patients were then followed for 12 months for investigation of recurrence of venous thromboembolism (VTE) and fatal events as adverse outcome. RESULTS The mean age of the patients was 62.8 years, and 78 (38.4%) were males. DVT was found in 118 (58.1%) patients. Of these patients, 61 (30.0%) had proximal DVT. Multivariate analysis demonstrated that active cancer, inadequate anticoagulation, leg symptoms, male gender, presence of DVT, presence of proximal DVT, and previous DVT were independent risk factors for adverse outcome. A clinical risk score ranging from 0 to 10 points was generated on the basis of multivariate regression coefficients. Receiver operating characteristic curve analysis showed that an appropriate cut-off point for discriminating between the presence and the absence of an adverse event was 4. Using this category, 166 (81.8%) patients were classified as low risk and 37 (18.2%) as high risk for adverse outcome. The adverse event rates were 6.0% for the low-risk group and 59.5% for the high-risk group. CONCLUSIONS This study has confirmed the clinical significance of surveillance CUS in patients with a first episode of PE. Furthermore, a simple risk score on the basis of available variables can identify patients at risk of an adverse outcome in patients with PE.

Abstract
BACKGROUND The presence of reflux in the femoral vein (FV) and popliteal vein (POPV) after acute deep vein thrombosis (DVT) is considered to contribute to the development of advanced post-thrombotic syndrome (PTS). However, a quantification of reflux has yet to be determined. The purpose of study was to determine the indicative parameters reflecting the progression of PTS. METHODS Venous abnormalities were evaluated in 131 limbs out of 130 patients who completed a six-year follow-up after an acute DVT. Clinical manifestations were categorized according to the clinical, etiologic, anatomic, and pathophysiologic (CEAP) classification, and the patients were divided into two groups at a six-year follow-up point: group I, C(0-3)E(s),A(s,d,p),P(r,o), early chronic venous insufficiency (CVI); group II, C(4-6)E(s),A(s,d,p),P(r,o), advanced CVI. Venous segments were examined whether they were occluded or recanalized. The reflux parameters assessed were the diameter (cm), the reflux time (RT; s), the peak reflux velocity (PRV; cm s(-1)), and total refluxed volume, and these parameters were assessed especially in the FV and POPV at the two-year (early phase) and subsequent six-year (late phase) follow-up points after DVT. RESULTS There were 98 limbs in group I and 33 in group II. The frequency of venous reflux was significantly higher in group II (<0.0001). In contrast, the proportion of occlusion did not differ between the groups (P = 0.138). The proportions of FV and POPV incompetence were significantly higher in group II (P < 0.0001 and P < 0.0001, respectively). In these veins, the RT did not improve the discrimination power between the two groups. In contrast, the PRV had significant discrimination power in these veins at both the two- and six-year follow-up points. In the superficial venous system, there were no significant differences in any of the determined parameters between the groups. In group II, 19 patients (58%), who had early symptoms of CVI at the two-year follow-up point, subsequently developed advanced symptoms of PTS. After calculating a suitable cutoff point using receiver operating characteristic curves analysis at the two-year follow-up point, multivariable analysis showed that a PRV of >25.4 cm s(-1) in the POPV was the strongest independent predictor of advanced CVI [odds ratio (OR) 60.32; 95% confidence interval (95CI) 43.1-1238.97, P < 0.0001]. Similarly, in the FV, a PRV of >24.5 cm s(-1) was found to be a strong predictor of advanced CVI (OR 25.77, 95CI 10.56-331.12, P < 0.0001). CONCLUSIONS These findings suggest that the presence of a high PRV in the proximal deep veins is an independent predictor of advanced symptoms of PTS.

Abstract
BACKGROUND Venous reflux can be elicited either manually or by pneumatic tourniquet, and previous studies did not indicate any significant difference between these manoeuvres in patients with superficial venous insufficiency (SVI). PURPOSE To investigate if two methods correlate in patients with CVI. MATERIALS AND METHODS Venous reflux was studied in 94 venous segments of 57 limbs in 52 consecutive patients with SVI. Limbs were divided into two groups: group I (CEAP C2-C3) and group II (CEAP C4-C6). A colour duplex scanner was used to determine quantitative venous reflux at the sapheno-femoral junction (SFJ), at the sapheno-popliteal junction (SPJ), and in the greater saphenous vein in the thigh (GSV). Patients received both manual compression and cuff deflation method in eliciting venous reflux. The parameters assessed were the duration of reflux (second) and the peak reflux velocity (cm/s). STATISTICS Paired t-test was used to evaluate differences between the two methods. Statistical significance was recorded when the p-value was <0.05. Bland and Altman plot was also used to assess the agreement of the same measurement. RESULTS There were 58 venous segments in group I and 36 in group II. In group I, there were no significant differences in the duration of reflux at the SFJ, SPJ, and in the GSV. On the contrary, peak reflux velocity was found to be significantly higher at the SFJ and in the GSV (p=0.022 and 0.006, respectively). In group II, there was no significant difference in the duration of reflux at the SFJ and SPJ between the two methods. On the contrary, manual compression maneuver produced significantly higher peak reflux velocity than at the SFJ and in the GSV (p=0.023 and 0.002, respectively). Bland and Altman plot analysis, manual compression method displayed a relatively good agreement with cuff deflation manoeuvre both in group I and group II. In contrast, concerning the peak reflux velocity, relative wide limits of agreement were found between the two methods. CONCLUSIONS Unlike previously published reports, our results lead to apparent discrepancies in the quantitative evaluation of venous reflux using different methodology.

Abstract
BACKGROUND To investigate patterns of venous insufficiency and changes in calf muscle deoxygenated hemoglobin (HHb) levels after an acute deep vein thrombosis (DVT). METHODS A total of 78 limbs with an acute DVT involving 156 anatomic segments were evaluated with duplex scanning and near-infrared spectroscopy (NIRS) at 1, 3, 6 and 12 months. Venous segments were examined whether they were occluded, partially recanalized, and totally recanalized, and the development of venous reflux was noted. The NIRS was used to measure calf muscle HHb levels. Calf venous blood filling index (HHbFI) was calculated on standing, then the calf venous ejection index (HHbEI), and the venous retention index (HHbRI) were obtained after exercise. RESULTS The segments investigated were the common femoral vein (CFV; 38 segments), femoral vein (FV; 37), popliteal vein (POPV; 44), and calf veins (CV; 37). At 1 year, thrombi had fully resolved in 67% of the segments, 27% remained partially recanalized, 6% were occluded. The venous occlusion was predominant in the FV (24%) at 1 year. On the contrary, rapid recanalization was obtained in CV than proximal veins at each examination (P < 0.01). Venous reflux was predominant in POPV (55%), followed by FV (19%), and no reflux was found in CV. At 1 year, the HHbFI in POPV reflux patients was significantly higher than those with resolution (0.19 +/- 0.14, 0.11 +/- 0.05 microm s, P = 0.009, respectively). Similarly, there was a significant difference in the HHbRI between the two groups (3.08 +/- 1.91, 1.42 +/- 1.56, P = 0.002, respectively). In patients with FV occlusion, the value of HHbRI was significantly higher than those with complete resolution (2.59 +/- 1.50, 1.42 +/- 1.56, P = 0.011, respectively). CONCLUSIONS The lower extremity venous segments show different proportions of occlusion, partial recanalization, and total recanalization. The CV shows more rapid recanalization than proximal veins. The NIRS-derived HHbFI and HHbRI could be promising parameters as the overall venous function in the follow-up of acute DVT. These findings might be very helpful for physician in detecting patients who require much longer follow-up studies.

Abstract
PURPOSE We evaluated the clinical significance of hypofractionated high-dose irradiation using simultaneous integrated boost technique with intensity-modulated radiation therapy (IMRT) for the treatment of malignant astrocytomas (MAs). METHODS AND MATERIALS Twenty-five patients with MAs were treated by IMRT. Three layered planning target volumes (PTVs) were contoured. PTV-1 was the area of enhanced lesion with 5-mm margin; PTV-2 was the area with 15-mm margin surrounding the PTV-1; PTV-3 was the area of perifocal edema. Irradiation was performed in 8 fractions, and only the dose for PTV-1 was escalated from 48 Gy to 68 Gy while maintaining the dose for PTV-2 (40 Gy) and PTV-3 (32 Gy). The clinical outcome of IMRT was compared with 60 MA patients treated by conventional external beam irradiation (EBI). RESULTS The progression-free survival of patients in the IMRT group was significantly longer than that in the EBI group (p < 0.0001). No distant failure was observed in both groups. In the IMRT group, dissemination was the most frequent cause of death (70%). The overall survival of patients in the IMRT group was better than that in the EBI group (p = 0.043). CONCLUSIONS Our regimen of IMRT contributed to the control of both the regional and infiltrating tumors, resulting in better survival of patients.

Abstract
We report here the case of a 29-year-old woman with cerebellar glioblastma. In the present case, tumor lesions were observed in each cerebellar hemisphere. The left-side lesion was diagnosed as glioblastoma, and the right-side lesion as malignant astrocytoma by histopathology. Immunohistochemistry revealed that the tumor cells of the left-side lesion was positive for p53, whereas epidermal growth factor receptors (EGFR) were negative in tumor cells from both sides. Genetic alterations were investigated using a genome DNA microarray (GenoSensor Array 300), which has led us to define this tumor as a secondary glioblastoma. The clinical presentation and genetic findings of this relatively rare entity are discussed.

Abstract
We report the case of a 16 year old girl with vertical-torsional oscillations. She had a 4 year history of bilateral horizontal gaze palsy caused by a cavernous angioma in the medial part of the dorsal pons. She presented with vertical oscillopsia that had worsened during the past 3 months. Unilateral three dimensional eye movements and bilateral horizontal eye movements were recorded using a magnetic search coil method and direct current electro-oculography, respectively. She had vertical-torsional oscillations (average frequency: 3.0 Hz) leaving vertical saccades and pursuits intact. The average amplitudes of the vertical and torsional components were 2.0 degrees and 0.6 degrees , respectively. Her horizontal rapid eye movements were severely impaired; however, her horizontal pursuits and slow phases of vestibulo-ocular reflex were only partially impaired (gain<0.3, oculomotor range<+/-9 degrees ). Convergence and divergence were intact. Lesions involving the medial part of the dorsal pons and bilateral paramedian pontine reticular formation can induce vertical and torsional oscillations without disruption of vertical rapid eye movements.

Abstract
We investigated the hemodynamic pattern of serum hyaluronic acid (HA) and compared it with that of plasma phosphatidylcholine hydroperoxide (PCOOH) in terms of a convenient parameter of reperfusion injury. Using pig models, we designed two continuous ischemia groups, prepared by blockage of the blood flow at the hepatic hilum for 10 or 30 min. A discontinuous ischemia model was prepared by repeating the 10-min ischemia procedure, followed by 10 min of reperfusion, to a total ischemia period of 30 min. The PCOOH level started to increase just after reperfusion and reached the peak at 90 min, followed by a gradual decline after 6 h. The HA level increased rapidly in the continuous ischemia groups, starting immediately after ischemia onset until immediately before reperfusion, followed by a gradual decrease during up to 6 h of reperfusion. The HA levels in the three groups were almost normalized after 90 min of reperfusion, when the PCOOH level reached the peak. These results indicated that the plasma PCOOH level is a useful parameter for predicting the onset and progress of reperfusion injury in its initial stages.

Abstract
A case of ovarian fibrosarcoma producing multiple cytokines is presented. The tumor occurred in the left ovary of a Japanese woman with epigastralgia, remittent fever, leukocytosis and slight thrombocytosis with moderate increase of mast cells in bone marrow, but lack of hormonal abnormality. The resected tumor of the ovary was well encapsulated and it was composed of spindle-shaped tumor cells and scattered tubules with marked mast cell infiltration. The tumor recurred in the pelvic cavity 14 months later, accompanied by similar signs and symptoms as occurred with the primary tumor. Serum levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha were elevated. The recurrent tumor showed similar histological findings to those of the primary tumor, except for lack of tubules. Tumor cells revealed a focally positive immunoreaction for vimentin, IL-6 and TNF-alpha and alpha-inhibin. Reverse transcription-polymerase chain reaction using total RNA obtained from the recurrent tumor demonstrated mRNA expression of IL-6, IL-10, TNF-alpha and stem cell factor. This is a rare case of ovarian fibrosarcoma producing multiple cytokines, resulting in atypical clinical findings.

Abstract
We attempted a new regimen of intermittent administration of 5-FU and low-dose Isovorin (F.I) to four patients with advanced and recurrent colon cancer. A partial response (PR) was achieved in two of four patients who had evaluable lesions for this treatment. We observed few side effects among these patients. Only one patient among four showed grade 1 neuropathy after two administrations of this chemotherapy. However, after a two-week pause in administration, the neuropathy disappeared and we could continue the therapy. This patient with multiple liver metastases achieved a partial response. Other patients had no side effects such as bone marrow suppression or digestive symptoms. This intermittent F.I treatment might be an effective and promising therapy with few side effects even for patients with poorer conditions.

Abstract
We administered 5-FU and CDDP (FP) intermittently to four patients with advanced and recurrent gastric cancer. A minor response (MR) and partial response (PR) were achieved in two of four patients who had evaluable lesions for this treatment, and few side effects were observed. Only one patient among six showed grade 2 leucocytopenia after 15 administrations of this chemotherapy, when she had attained a partial response in a lung metastasis. The other patients had no side effects such as bone marrow suppression or digestive symptoms. This intermittent FP treatment may be an effective and promising therapy with few side effects even for the patients with serious conditions.
