Abstract
INTRODUCTION AND IMPORTANCE The Kasabach-Merritt Phenomenon (KMP), characterized by thrombocytopenia and consumptive coagulopathy due to endothelial cell growth in the infantile vascular tumor kaposiform hemangioendothelioma, presents a therapeutic challenge. This case highlights the novel use of sirolimus in a neonate, an approach less explored in this age group. CASE PRESENTATION A female neonate presented with a right anterior chest mass, progressing to respiratory distress and congestive heart failure. Diagnosed with KMP, she exhibited low platelet count and coagulation abnormalities. Treatment with sirolimus (0.06 mg/day) led to mass reduction, improved bleeding, and a stable tumor after 12 months, without side effects. This case contrasts with existing literature advocating for combination therapy or higher sirolimus concentrations for effective treatment. Yet, our patient achieved favorable outcomes with low-dose monotherapy, suggesting a potentially safer approach in neonates with immature hepatic and renal metabolism. CLINICAL DISCUSSION This case demonstrates the efficacy of low-dose sirolimus monotherapy in treating KMP in a neonate, challenging current preferences for combination therapies or higher doses. It emphasizes the need for further research into age-specific treatment protocols in KMP, considering the unique metabolic profiles of neonates and infants. CONCLUSION Sirolimus has demonstrated potential in treating KMP in pediatric patients. While initial results are promising, determining optimal dosages and trough concentrations, especially in neonates and infants, remains essential.

Abstract
Introduction Intractable lymphatic anomalies (LAs) include cystic lymphatic malformation (LM; macrocystic, microcystic, or mixed), generalized lymphatic anomaly, and Gorham-Stout disease. LAs can present with severe symptoms and poor prognosis. Thus, prospective studies for treatments are warranted. We conducted a prospective clinical trial of sirolimus for intractable LAs. Methods This was an open-label, single-arm, multicenter, prospective trial involving five institutions in Japan. All patients with LAs received oral sirolimus once daily, and the dose was adjusted to ensure that the trough concentration remained within 5-15 ng/mL. We prospectively assessed the drug response (response rate for radiological volumetric change in target lesion), performance state, change in respiratory function, visceral impairment (pleural effusion, ascites, bleeding, pain), laboratory examination data, quality of life (QOL), and safety at 12, 24, and 52 weeks of administration. Results Eleven patients with LAs (9 generalized lymphatic anomaly, 1 cystic LM, 1 Gorham-Stout disease) were treated with sirolimus, of whom 6 (54.5%; 95% confidence interval: 23.4-83.3%) demonstrated a partial response on radiological examination at 52 weeks of administration. No patients achieved a complete response. At 12 and 24 weeks of administration, 8 patients (72.7%) already showed a partial response. However, patients with stable disease showed minor or no reduction after 12 weeks. Adverse events, such as stomatitis, acneiform dermatitis, diarrhea, and fever, were common with sirolimus. Sirolimus was safe and tolerable. Conclusion Sirolimus can reduce the lymphatic tissue volume in LAs and may lead to improvements in clinical symptoms and QOL.

Abstract
Solid pseudopapillary neoplasm (SPN) is a rare pancreatic tumor that typically affects young women in the body and tail of the pancreas. SPN is often asymptomatic in the early stages, so it is initially discovered as a large tumor. In this report, we experienced a case of a relatively small SPN discovered in the setting of acute pancreatitis. Because there have been few reports of SPN being discovered in the situation like our case, we report this case based on a review of the literature.

Abstract
BACKGROUND Transient abnormal myelopoiesis (TAM) is characterized by leukocytosis with increased circulating megakaryoblasts that harbor N-terminal truncating mutations in the GATA1 gene. Approximately 10% of affected patients experience early death. OBSERVATIONS A 2-month-old boy with Down syndrome was diagnosed with TAM and followed without treatment. Although the blasts in the peripheral blood disappeared, liver failure progressed. A pathological examination revealed liver fibrosis, and double-immunostaining for full-length GATA1 and CD42b identified megakaryocytes with a GATA1 mutation. CONCLUSIONS This simple and cost-effective method can be applied in routine practice to detect TAM blasts during assessment in a TAM crisis.

Abstract
Multifocal lymphangioendotheliomatosis with thrombocytopenia is a rare disease characterized by progressive multiple vascular lesions and is accompanied by thrombocytopenia. The precise diagnosis of this disease is frequently difficult because of the heterogeneity of the clinical symptoms. We report a case of a male infant who presented with severe thrombocytopenia induced by local inflammation. In addition, enlargement of the extremities with soft tissue and bone involvement without gastrointestinal bleeding was observed. The thrombocytopenia resolved after a combination therapy of sirolimus and prednisolone. Our finding that plasma angiopoietin-2 concentrations reflected the disease status suggests its utility as a biomarker of Multifocal lymphangioendotheliomatosis with thrombocytopenia.

Abstract
Introduction Acute acquired comitant esotropia (AACE) is an acquired strabismus with uncrossed sudden-onset diplopia due to esodeviation, comitant esotropia without accommodation factor, or paretic eye movement. The diagnosis of AACE entails differentiation from incomitant esotropia caused by abnormalities in the central nervous system. We present 2 pediatric patients with AACE as the first symptom of brainstem tumor. Case Presentation The 2 patients were aware of their diplopia and had no other neurological abnormalities. There were no special findings in the anterior segment, ocular media, or fundus. Esotropia with a difference of no more than 10Δ between distant and near fixations was observed. Eye movements were normal, and Hess red-green test under prism neutralization did not reveal abduction restriction. The presumed cause of AACE in both patients was excessive use of digital displays, and brain magnetic resonance imaging (MRI) was performed to confirm the absence of neurological abnormality. Using MRI, a definitive diagnosis of AACE was made based on comitant esotropia associated with diffuse median glioma and medullary pilocytic astrocytoma without abducens nerve palsy. Conclusion Although the incidence of AACE caused by brainstem tumors may be low, it is necessary to perform head imaging to confirm etiology. Furthermore, Hess red-green test under prism neutralization is considered important for the differentiation of abducens nerve palsy.

Abstract
Regarding the prognosis of cases with advanced-stage hepatocellular carcinoma (HCC), a recent clinical study showed that the immune checkpoint inhibitors atezolizumab plus bevacizumab have superior efficacy to sorafenib. However, only a few reports have focused on their effects on extrahepatic metastases. We herein report a case of HCC in a 59-year-old man with intrahepatic lesions treated successfully by hepatic arterial chemoembolization, radiotherapy, and sorafenib; the extrahepatic lesion in the adrenal gland was treated by atezolizumab plus bevacizumab. The patient showed a tumor-free condition for one year. We have summarized the clinical course and reviewed the literature to underscore the efficacy of atezolizumab plus bevacizumab for treating extrahepatic lesions of HCC.

Abstract
Poorly differentiated chordoma (PDC) is a rare, aggressive subtype of chordoma. A two-year-old girl presented with cervical pain, limb paralysis and respiratory failure. Magnetic resonance imaging and positron emission tomography-computed tomography revealed a tumor compressing the pons at the clivus and osteoblastic metastatic lesions of the left upper arm and right iliac bone. Her tumors shrank substantially after treatment with chemotherapy and proton beam therapy. Our initial diagnosis was an atypical teratoma/rhabdoid tumor, but final diagnosis of PDC was made on the basis of the immunohistochemical expression of brachyury. In addition, the detection of SMARCB1/INI1 mutation confirmed the diagnosis of PDC.

Abstract
BACKGROUND Interventional radiology (IVR), including balloon-occluded retrograde transvenous obliteration (BRTO) and percutaneous transhepatic obliteration (PTO), is performed for patients with intractable hepatic encephalopathy (HE). However, information on the appropriate coil for endovascular coiling for preventing recanalization is lacking. This study aimed to compare the different types of coils for endovascular coiling used in BRTO and PTO for cases of intractable HE. METHODS This retrospective study included patients who underwent endovascular coiling with BRTO or PTO for HE caused by portosystemic shunts. The number of coils required for complete occlusion was compared among bare, fiber, and hydrogel-coated coils, and the expansion types that close the gap between and inside the hydrogel-coated coils were also compared. RESULTS Of 38 patients (age range, 30-86 years), 16 and 22 underwent BRTO and PTO, respectively, using bare (19 patients), fiber (8 patients), and hydrogel-coated coils (10 patients; external expansion type, 4; internal expansion type, 6). No significant differences in the size of portosystemic shunts were observed according to the type of coil. The mean number of coils required for complete occlusion varied (bare coils, 19.32; fiber coils, 18.11; hydrogel-coated coils, 10.70). Significantly fewer coils were required for endovascular coiling with hydrogel-coated coils. In the internal expansion type, a mean of 8.5 coils was required for occlusion. CONCLUSIONS In some patients who underwent portal vein embolization, complete occlusion was not achieved with the scheduled type of coil because of slight expansion of blood vessels due to coil pressure. The findings suggested that hydrogel-coated coils were effective in endovascular coiling for HE caused by a portosystemic shunt, and internal expansion-type hydrogel-coated coils may be effective for the first-line procedure.

Abstract
RATIONALE McCune-Albright syndrome (MAS) is a rare disorder characterized by clinical findings, which includes fibrous dysplasia (FD). FD is a benign tumor that leads to increased rates of bone fracture. In some MAS cases with FD, facial deformities, severe pain, and orbital neuropathies are complicated. Aneurysmal bone cyst (ABC) is a benign bone tumor and rare complication of FD. PATIENT CONCERNS A 9-year-old boy was admitted to our hospital because of acute visual disturbance. DIAGNOSIS AND INTERVENTIONS The patient was clinically diagnosed as ABC complicated with MAS, and he underwent surgery. OUTCOMES After the surgery, his sight became normal. Recurrence of ABC and visual disturbance was not observed in 3 years. Genetic analysis of a tissue sample from the ABC lesion by next-generation sequencing revealed a somatic activating GNAS mutation. LESSONS To the best of our knowledge, this is the first case report of MAS causing optic neuropathy complicated with ABC. ABC complicated with MAS is extremely rare, but it should be considered as a possible diagnosis in patients with acute visual loss and facial swelling. In addition, our case had OAS, which is an uncommon syndrome and a rare complication in ABC with MAS, and rapid decompression of the ABC was effective in improving the patient's eyesight.

Abstract
Giant cell glioblastoma (GCG) is a rare subtype of glioblastoma multiforme (GBM), and it often occurs in younger patients; however, its onset in children is extremely noticeable. A 7-year-old girl presented with a headache and restlessness. A giant tumor that was 7 cm in diameter was found by magnetic resonance imaging (MRI) in the left frontal lobe with intracranial dissemination. Because the tumor had extended to the lateral ventricles and occluded the foramen of Monro causing hydrocephalus, she underwent ventricular drainage and neuro-endoscopic biopsy from the left posterior horn of the lateral ventricle. The initial pathological diagnosis was an atypical teratoid/rhabdoid tumor (AT/RT). When the dissemination subsided after the first chemotherapy with vincristine, doxorubicin, and cyclophosphamide, she underwent the first tumor resection via a left frontal transcortical approach. After surgery, the second chemotherapy with ifosfamide, cisplatin, and etoposide was not effective for the residual tumor and intracranial dissemination. The second surgery via a transcallosal approach achieved nearly total resection leading to an improvement of the hydrocephalus. The definitive pathological diagnosis was GCG. Despite chemo-radiation therapy, the dissemination in the basal cistern reappeared and the hydrocephalus worsened. She was obliged to receive a ventriculo-peritoneal (VP) shunt and palliative care at home; however, her poor condition prevented her discharge. Ten months after admission, she died of tumor progression. The peritoneal dissemination was demonstrated by cytology of ascites. In conclusion, although unusual, pediatric GCG may be disseminated at diagnosis, in which case both tumor and hydrocephalus control need to be considered.

Abstract
BACKGROUND Kaposiform lymphangiomatosis (KLA) is a recently characterized systemic lymphatic anomaly. Activation of RAS/MAPK and PI3K/AKT/mTOR pathways may affect KLA pathogenesis, but the cellular basis of KLA is unclear. Abnormal-spindle endothelial cells that express lymphatic endothelial cell (LEC) markers are characteristic of KLA histopathology. This study evaluated patient-derived KLA cells to establish their morphological and biological characteristics. PROCEDURE We established cell lines from primary KLA tissues of two patients with KLA and examined their morphological and functional characteristics, messenger RNA and protein expression profiles, gene mutations, and responses to inhibitors of the RAS/MAPK and PI3K/AKT/mTOR pathways. RESULTS Both KLA cell lines showed spindle-shaped morphology, stained positive for podoplanin (PDPN), and exhibited impaired tube-formation properties. They expressed LEC marker PDPN and mesenchymal stem cell markers (CD90, CD105) in the absence of endothelial cell markers (CD34, CD31, VWF), per real-time polymerase chain reaction. Both mTOR inhibitor rapamycin and MEK inhibitor trametinib inhibited growth of the two cell lines. A NRAS p.Q61R variant was found in one of two independent KLA tissue samples, but not in the KLA cells (per targeted next-generation sequencing); and KLA cells with this variant had elevated AKT phosphorylation levels. ERK phosphorylation levels were undetectable in both KLA cell lines. CONCLUSIONS Inhibition of the RAS/MAPK and PI3K/AKT/mTOR pathways may represent potential therapeutic targets in KLA. These patient-derived KLA cell lines will be useful research tools to elucidate KLA etiology, and could pave the way for basic, translational, and preclinical studies of this disease.

Abstract
Desmoid-type fibromatosis (DTF) is a rare locally aggressive soft tissue neoplasm without metastatic potential. Here, we report a very rare sporadic case of an intracranial supratentorial extradural DTF measuring 82 mm in a 1-year-old girl, that recurred twice following surgery over the course of 16 months, requiring two other surgeries. In three surgeries, we resected a huge tumor with the dura which was thought to be tumor origin and removed this tumor infiltrated the frontal skull base by drilling widely. Furthermore, we treated the tumor invading the bone flap using liquid nitrogen for 20 minutes, and subsequently used it to perform a cranioplasty. This tumor has not recurred for past 8 months. DTF invading the skull base is prone to recurrence, and liquid nitrogen treatment is considered to be effective in pediatric patients, who need cranioplasty with tumor-infiltrating autologous bone flaps.

Abstract
Vascular anomalies comprise a heterogeneous group of disorders caused by abnormal proliferation or development of vascular and/or lymphatic vessels. Vascular anomalies present with various symptoms and complications, but no standardized methods evaluate their severity, and to measure treatment outcomes is difficult. To assess the responsiveness of measurement scores for evaluating vascular anomaly skin lesions, we conducted a validation study to compare these measurement scores with patients’ objective data. In this study, data were collected from treated and untreated patients. Skin lesions were photographed at baseline and after a follow‐up period of 3–6 months. The volume of skin lesions, the degree of red or purple coloration, and color tone were measured objectively. Two external dermatologists evaluated patients’ photographs and determined scores, which represented criteria for improvements in skin lesions (size and color) and 6‐point Physician Global Assessment scores. The correlation between these scores and patients’ objective data (lesion volume and color) was assessed to validate the scores. Twenty‐three cases of vascular anomaly (seven vascular tumors, five lymphatic malformations, three venous malformations, and eight lymphatic–venous malformations) were examined. Scores for improvements in vascular anomaly skin lesions (size and color) correlated with a change in lesion volume, the degree of red or purple coloration, color tone score, and 6‐point Physician Global Assessment score. Our findings suggest that these measurement scores are responsive to changes in vascular anomaly skin lesions after observation.

Abstract
Introduction
Extracellular signal-regulated kinase (ERK) modulates differentiation and maturation of adipocyte and the hypertrophy and differentiation of adipocytes affected the vascular diseases in obese. Changes in characters of adipocytes could develope the oxidative stress and inflammations. Moreover, changes in perivascular adipose tissue (PVAT) could modulate vascular tonus in obesity. However, the role of adipose ERK2 in endothelial function and characters of PVAT in obese in vivo had not been clarified, yet.
Purpose
This study aims to elucidate the role of the adipose ERK2 in endothelial-dependent relaxation (EDR) in mice model of obesity. The role of PVAT in EDR was also assessed.
Methods and results
We created adipose-specific ERK2 knock out mice (AE2KO) by crossing fatty acid binding protein 4 Cre and ERK2 flox mice and fed them with normal diet (ND) or high fat/ high sucrose diet (HFHSD) for 24 weeks. AE2KO fed with HFHSD gained more weight and revealed the heterogeneity in sizes of adipocyte in subcutaneous fat (SF). Furthermore, the mRNA levels of lipoprotein lipase, hormone-sensitive lipase, and peroxisome proliferator-activated receptor γ, which was the master genes of adipocyte differentiation, were markedly down-regulated in SF. PVAT in AE2KO with HFHSD was markedly enlarged and the mRNA expression of inflammatory adipocytokines, such as IL-1β and leptin were up-regulated. Next, we assessed EDR by acetylcholine (ACh) -induced relaxation in aortic rings with or without PVAT. EDR without PVAT was modestly decreased in AE2KO with HFHSD compared with wild type mice (WT) with HFHSD. Aortic rings with PVAT increased EDR in WT with ND. PVAT modestly decreased EDR in WT with HFHSD and mostly eliminated EDR in AE2KO with HFHSD. To assess the contraction factors released from PVAT, the solutions incubated with PVAT (SIP) were transferred to the normal aortic rings. SIP from WT with HFHSD mildly increased vascular tone and SIP from AE2KO with HFHSD further increased it. Tempol, which was superoxide scavenger, restored endothelial dysfunction with PVAT and suppressed the contraction with SIP from AE2KO with HFHSD. Fluorescence intensity of dihydroethidium stain of aorta and PVAT, which indicated that aortic and adipose superoxide production were elevated in AE2KO with HFHSD, which were mostly eliminated with tempol.
Conclusions
Adipose ERK2 selectively modulated differentiation in SF, suppressed the aortic oxidative stress and protected from endothelial dysfunction in obese. Moreover, adipose ERK2 suppressed the hypertrophy, inflammation, and oxidative stress of PVAT in obese. The oxidative stress with the inflammation in PVAT released vasoconstriction factors, which contributed to endothelial dysfunction in obese mice.

Abstract
We describe a new member of the aldo-keto reductase (AKR) superfamily in the silkworm Bombyx mori. On the basis of its amino acid sequence and phylogenetic tree, this AKR belongs to the AKR1B family and has been designated as bmALD1. In the current study, recombinant bmALD1 was overexpressed, purified to homogeneity and kinetically characterized. We discovered that bmALD1 uses NADPH as a coenzyme to reduce carbonyl compounds such as DL-glyceraldehyde, glucose and 2-nonenal. No NADH-dependent activity was detected. To the best of our knowledge, bmALD1 is only the third AKR characterized in silkworm which, given its substrate specificity, could play a major role in glucose metabolism and antioxidant reactions. Our data provide an increased understanding of insect AKR function.

Abstract
Few hematological complications have previously been reported in association with Cri du Chat syndrome (CdCS). A case of myelodysplastic syndromes (MDS) in a pediatric patient with CdCS is herein presented. A 17-year-old female with CdCS caused by ring chromosome 5 was admitted to the hospital for investigation of a 1-month history of anemia. Based on the morphological findings of bone marrow, the patient was diagnosed with refractory cytopenia with multilineage dysplasia. The risk group was classified as intermediate-1 in the International Prognostic Scoring System (IPSS), and low in the revised IPSS. Assessment by microarray comparative genomic hybridization (CGH) identified the breakpoints of ring chromosome 5 as 46,XX,r(5)(p14.3q35.3). This revealed that the 5q terminal deletion did not include the common deleted region of MDS with del(5q). Treatment with azacitidine was initiated to control disease progression and improve quality of life. At baseline, the patient had a mean transfusion requirement of 3 units/month, which decreased to 2 units/month after six cycles of azacitidine and to 1 unit/month after 10 cycles of azacitidine. Cytopenia observed in the presented case seemed irrelevant to ring chromosome 5 which is the causative cytogenetic abnormality of CdCS, and further analyses may be needed to clarify the pathogenesis.

Abstract
Objective Rifaximin has become available for treating hyperammonemia in patients with hepatic encephalopathy. This study analyzed the changes in the body composition and nutritional status after long-term rifaximin therapy. Methods Twenty-one patients who underwent rifaximin therapy at 1,200 mg/day for more than 24 weeks were evaluated for the changes in the controlling nutritional status (CONUT) scores for the nutritional assessment, albumin-bilirubin (ALBI) scores for the liver function assessment, and skeletal muscle index (SMI) for the body composition assessment. Results There were 17 men and 4 women, with a mean age of 67.14±8.32 years. Eleven cases had a portosystemic shunt (52.3%), and 10 had hepatocellular carcinoma (47.6%). The Child-Pugh class was A in 9 cases (42.9%), B in 9 cases (42.9%), and C in 3 cases (14.2%). The blood ammonia levels in the rifaximin group improved significantly upon rifaximin therapy, from 124.76±28.68 μg/dL at baseline to 47.00±14.43 μg/dL after 2 weeks (p<0.001) and 49.81±15.02 μg/dL after 24 weeks (p<0.001). The CONUT scores improved significantly during rifaximin therapy, from 6.47±3.25 at baseline to 3.33±2.65 after 24 weeks (p=0.0007). The ALBI scores also improved significantly from -0.39±1.89 at baseline to -2.20±0.55 after 24 weeks (p=0.0002). The SMI scores showed that the body composition had been maintained in response to rifaximin therapy (50.20±7.67 at baseline and 51.29±7.62 after 24 weeks). Conclusion Rifaximin administration for hepatic encephalopathy improved the CONUT and ALBI scores. It may have a secondary effect on the improvement in the nutritional status and hepatic reserve.

Abstract
Abstract
Introduction
Metabolic syndrome (MetS) is well known as the risk of cardiovascular diseases associated with endothelial dysfunction and induces steatohepatosis. Insulin resistance is a major character of MetS, which affects intracellular signaling pathways and endothelial function. Extracellular signal-regulated kinase (ERK) is a major component of insulin signal and many of vasoactive peptides, which were released in MetS, can activate it in endothelium. However, the role of endothelial ERK in nitric oxide (NO) bioactivity in MetS in in vivo has been unknown.
Purpose
The aim of this study is to clarify the role of endothelial ERK2 on NO bioactivity in mice model of MetS.
Methods and results
We created endothelial specific ERK2 knock out mice (EE2KO) crossing Tie2-Cre mice and ERK2 flox mice and fed them with normal or high-fat/high-sucrose diet (HFHSD) for 24 weeks. Serum glucose and insulin levels and HOMA-IR were lowered in EE2KO with HFHSD without changing body weight. In wild type mice (WT) with HFHSD, nonalcoholic fatty liver disease (NAFLD) activity score, fibrosis score and serum ALT level were increased, all of which were blunted in EE2KO. EE2KO with HFHSD lowered systolic blood pressure (WT: 123.7±5.83 mmHg, EE2KO: 101.4±3.66 mmHg, P<0.01, N=8) without changing heart rate, which was increased to the same levels with L-NAME, an endothelial NO synthase inhibitor, in both groups. Serum NO levels measured with serum nitrite/nitrate concentrations were increased in EE2KO with HFHSD (WT: 23.10±3.74 μmol/l, EE2KO: 41.71±6.73 μmol/l, P<0.05, N=12). Endothelial function was assessed with the isometric tension measurement of aortic rings with acetylcholine (ACh). ACh-induced relaxation was improved in EE2KO with HFHSD. Superoxide production of aorta from EE2KO was lowered than WT with HFHSD in dihydroethidium (DHE) staining. S18886, an antagonist of the thromboxane A2-prostanoid (TP) receptor, decreased superoxide production of aorta in DHE staining resulting in improving endothelial function in the isometric tension measurement of aortic rings. Oral administrations of S18886 decreased systolic blood pressure, serum fasting glucose and insulin levels, and surprisingly improved steatohepatosis by decreasing NAFLD activity score and fibrosis score.
Relaxation of aortic rings with ACh
Conclusions
Endothelial ERK2/TP receptor pathway increases superoxide production and decreased NO bioactivity, resulting in deteriorating endothelial function, insulin resistance and steatohepatosis, which were improved by antagonist of the TP receptor in mice model of MetS. The present study indicates that ERK2/TP pathway could be a therapeutic target for complications of MetS.

Abstract
Background Kaposiform lymphangiomatosis (KLA) has recently been distinguished as a novel subtype of generalized lymphatic anomaly (GLA) with foci of spindle endothelial cells. All cases of KLA involve multiple organs and have an unfavorable prognosis. However, the molecular pathogenesis is unknown, and there are no useful biomarkers. In the present study, we performed genetic analysis to elucidate the cause of this disease and detect biomarkers for it. Methods We performed whole-exome sequencing of DNA samples from leukocytes and a biopsy specimen and analyzed cell-free DNA (cfDNA) from plasma and pleural effusion of patients to identify the NRAS c.182A > G (p.Q61R) mutation using the droplet digital polymerase chain reaction (ddPCR). Results All KLA patients (patients 1–5) had invasive and aggressive features (hemorrhagic pleural effusions, coagulation disorder, and thrombocytopenia) and characteristic findings of KLA in their pathological examinations. In whole exome sequencing for patient 1, c.182A > G missense variant (p.Q61R) in NRAS was identified in fresh frozen samples of a mass on the left chest wall at a frequency of 5% of total alleles but not in his blood leukocytes. Furthermore, the same mutation was detected in cfDNA isolated from plasma and pleural effusion by using ddPCR. ddPCR analysis of plasma/pleural effusion samples from an additional four KLA patients showed that the same mutation was detected in isolated cfDNA in three of the four, as well as in a tissue sample from one of the three plasma/effusion-positive patients that had been obtained to confirm the mutation. Conclusion These results provide the first evidence that NRAS oncogenic variant was identified in DNA samples from KLA patients from not only two affected lesions but also plasma and pleural effusion.

Abstract
BACKGROUND Lymphatic anomalies (LAs) include several disorders in which abnormal lymphatic tissue invades the neck, chest, and various organs. Progressive cases may result in lethal outcomes and have proven difficult to treat. Sirolimus is showing promising results in the management of vascular anomalies. We examined the efficacy and safety of sirolimus treatment in patients with progressive LAs. METHODS All patients with LAs treated with sirolimus from May 2015 to September 2018 were included. They received oral sirolimus once a day and the dose was adjusted so that the trough concentration remained within 5-15 ng/mL. We prospectively reviewed the response to drugs (the response rate of radiological volumetric change of the target lesion), severity scores, reported quality of life (QOL), and adverse effects at 6 months after administration. RESULTS Twenty patients (five with cystic lymphatic malformation (LM), three with kaposiform lymphangiomatosis, three with generalized lymphatic anomaly, six with Gorham-Stout disease, and three with central conducting lymphatic anomaly) were treated with sirolimus at our institution. Fifty percent of patients (10/20) demonstrated a partial response by a radiological examination and a significant improvement in disease severity and QOL scores (P = 0.0020 and P = 0.0117, respectively). Ten patients who had no reduction in lesion size (stable disease group) showed no significant improvement in disease severity and QOL scores. Eighty percent of patients (16/20) had side effects, such as stomatitis, infection, and hyperlipidemia. CONCLUSIONS Sirolimus impacts the reduction of the lymphatic tissue volume of LMs and could lead to improvement in clinical symptoms and QOL.

Abstract
OBJECTIVES An operations leader (OL) takes an important role in occupational health management for radiation decontamination workers in Japan, and candidates for the position must participate in a training session to acquire the necessary knowledge as required by law. However, it has not been clarified whether the candidates for the OL position actually possess accurate knowledge regarding occupational health management for such work after the training session. We, therefore, aimed at examining the current occupational health management knowledge among the candidates and investigating factors related to the knowledge, with hypothesis that possession of accurate knowledge is associated with prior experience of having worked in radiation decontamination. DESIGN A cross-sectional study. SETTING The training sessions held by Fukushima Prefecture Labor Standard Associations in Fukushima, Japan, in 2017. PARTICIPANTS Eighty male candidates participated in the training sessions. OUTCOME The number/proportion of correct answers to the questions regarding occupational health management, such as those on working environment management, control of operations and health management. RESULTS The proportion of those who possessed accurate knowledge regarding working environment management, control of operations and health management was 68.8%, 55.0% and 51.2%, respectively. Experience of radiation decontamination work was associated with the possession of inaccurate knowledge regarding working environment management (OR 0.140 (95% CI 0.042 to 0.464)), and the uncertainty of future radiation decontamination work schedules in difficult-to-return zones was associated with the possession of accurate knowledge regarding health management (OR 4.344 (95% CI 1.509 to 12.50)). CONCLUSIONS Previous experience in radiation decontamination work may hinder the ability to acquire accurate information regarding working environment management among candidates for an OL position. To promote adequate occupational health management for radiation decontamination workers, it is required to establish an effective instructional method for the OL candidate training sessions with consideration of previous relevant experience.

Abstract
We previously reported that PU.1 is downregulated in the majority of myeloma cell lines and primary myeloma cells of certain myeloma patients, and conditional expression of PU.1 in such myeloma cell lines induced cell cycle arrest and apoptosis. We found downregulation of IRF4 protein in the U266 myeloma cell line following induction of PU.1. Previous studies reported that knockdown of IRF4 in myeloma cell lines induces apoptosis, prompting us to further investigate the role of IRF4 downregulation in PU.1-induced cell cycle arrest and apoptosis in myeloma cells. PU.1 induced downregulation of IRF4 at the protein level, cell cycle arrest and apoptosis in six myeloma cell lines. Chromatin immunoprecipitation (ChIP) revealed that PU.1 directly binds to the IRF4 promoter, whereas a reporter assay showed that PU.1 may suppress IRF4 promoter activity. Stable expression of IRF4 in myeloma cells expressing PU.1 partially rescued the cells from apoptosis induced by PU.1. As it was reported that IRF4 directly binds to the IRF7 promoter and downregulates its expression in activated B cell-like subtype of diffuse large B cell lymphoma cells, we performed ChIP assays and found that IRF4 directly binds the IRF7 promoter in myeloma cells. It is known that IRF7 positively upregulates interferon-β (IFNβ) and induces apoptosis in many cell types. Binding of IRF4 to the IRF7 promoter decreased following PU.1 induction, accompanied by downregulation of IRF4 protein expression. Knockdown of IRF7 protected PU.1-expressing myeloma cells from apoptosis. Furthermore, IFNβ, which is a downstream target of IRF7, was upregulated in myeloma cells along with IRF7 after PU.1 induction. Finally, we evaluated the mRNA expression levels of PU.1, IRF4 and IRF7 in primary myeloma cells from patients and found that PU.1 and IRF7 were strongly downregulated in contrast to the high expression levels of IRF4. These data strongly suggest that PU.1-induced apoptosis in myeloma cells is associated with IRF4 downregulation and subsequent IRF7 upregulation.

Abstract
The residents of Suetsugi in Fukushima Prefecture measured ambient dose rates and radiocaesium concentrations in the soil after the accident at Fukushima Daiichi nuclear power plant in an attempt to maintain living conditions in the region. The measurements were colour plotted into maps to visualise the contamination. Through the receipt of external support, a number of radioactivity-related initiatives were implemented for the residents. Studies were also undertaken regarding the impact of radiocaesium contamination on rice farming in Suetsugi following the Great East Japan Earthquake and the accident at Fukushima Daiichi nuclear power plant.

Abstract
OBJECTIVE To investigate clinical characteristics and prognosis in tuberculosis (TB) patients and the transmission dynamics of TB after the 2011 Japan earthquake and tsunami. METHOD This was a retrospective observational cohort study. Data were analyzed among 93 pulmonary TB patients (tsunami-affected areas 25, non-tsunami areas 68) hospitalized during March 2011-March 2012 with 1-year follow-up since treatment commencement. Variable number of tandem repeats (VNTR) typing was conducted for 38 TB strains (tsunami-affected areas 21, non-tsunami areas 17). RESULTS Patients from tsunami-affected areas were significantly more likely to be refugees (OR 12.8, 95%CI 2.45-67.20), receive oxygenation (OR 5.0, 95%CI 1.68-14.85), and have a unique VNTR (OR 4.6, 95%CI 1.14-18.41). Patients who died within 1 year were significantly more likely to be older (OR 9.8, 95%CI 1.85-180.26), partially dependent or dependent (OR 11.9, 95%CI 4.28-37.62), and to require oxygenation (OR 4.3, 95%CI 1.47-12.89), and had lower serum albumin levels (OR 11.1, 95%CI 2.97-72.32). CONCLUSION Risk factors for prognosis of TB after the earthquake were associated with advanced age, low serum albumin level, functional status at admission, and oxygen requirement. The VNTR results suggest that most of the cases with pulmonary TB experienced reactivation of latent tuberculous infection, likely due to the impact of the earthquake and tsunami.

Abstract
OBJECTIVES The purpose of this study was to evaluate the effects of shor-term expansion treatment using the quad-helix appliance on dentofacial morphology in orthodontic patients presenting with a hyperdivergent facial pattern. METHODS The treatment group consisted of 40 patients with a hyperdivergent facial pattern, who were treated for maxillary incisor crowding with a quad-helix appliance during the mixed dentition period. Lateral cephalograms taken at the start (TO) and end (TI) of the treatment were obtained as a course of care. A similar number of patients, who possessed the same type of facial pattern and who remained untreated, were assigned to a control group. Two consecutive lateral cephalograms of each untreated patient were taken at the same time points as TO and T1. All cephalograms were traced, analysed and compared between the two groups. RESULTS The treatment changes as a result of the quad-helix appliance were expressed in an upward rotation of the mandible [2.34⁰] and distal tipping and impeded mesial movement of the maxillary first molars. Significant differences were evident between the treatment and control groups. CONCLUSION Quad-helix appliance treatment can be appropriate for significantly decreasing the mandibular plane angle in hyperdivergent patients presenting with moderate maxillary incisor crowding and a positive overjet and overbite.

Abstract
We treated a 62-year-old woman who suffered from intraventricular haemorrhage. Angiography revealed an arteriovenous shunt draining into a venous angioma. She was successfully treated by obliteration of the arteriovenous shunt with transarterial embolisation. Angiography performed after embolisation demonstrated that the persisting venous angioma served as the draning vein for normal middle cerebral artery perfusion. We believe that selective arterial occlusion with preservation of the venous component is the best treatment for this type of mixed vascular malformation.

Abstract
We evaluated retrospectively the treatment modalities and clinical outcome of 14 patients with intracranial dural arteriovenous fistula (AVF) involving cortical veins and dural sinuses except the cavernous and lateral sinuses. The location of arteriovenous shunt was the confluence of the sinuses and superior sagittal sinus (in 2 patients), superior petrosal sinus (1), marginal sinus (1), parasigmoid sinus (1), cortical vein at the anterior fossa (2), cortical vein of the parietal lobe (2), petrosal vein (2), and the cortical vein around the craniocervical junction (3). Of 12 patients who underwent endovascular and/or surgical treatment, five patients were treated only with microsurgery, six only with endovascular therapy, and one with combined surgical and endovascular procedure. Angioanatomical result was complete occlusion of the lesion in all the cases treated with surgery, and 80 to 100% occlusion in cases with endovascular treatment. Clinical outcome was GR in nine patients, MD in two, SD in one, VS in one, and D in one. The natural history of the lesion at each location and angioanatomical feature including the hemodynamic condition in each case should be precisely evaluated to select endovascular, surgical, or a combined procedure for the management of these unusual types of intracranial dural AVF.

Abstract
Whole exome sequencing (WES) technologies have accelerated genetic studies of Mendelian disorders, yielding approximately 30% diagnostic success. We encountered a 13-year-old Japanese female initially diagnosed with familial hypercholesterolemia on the basis of clinical manifestations of severe hypercholesterolemia (initial LDL cholesterol=609 mg/dl at the age of one) and systemic intertriginous xanthomas with histories of recurrent self-limiting episodes of fever and arthritis. Both her phenotypes seemed to co-segregate in a recessive manner. We performed WES on this patient, who was considered a proband. Among 206,430 variants found in this individual, we found 18,220 nonsense, missense, or splice site variants, of which 3,087 were rare (minor allele frequency ≤ 0.01 or not reported) in 1000 Genome (Asian population). Filtering by assuming a recessive pattern of inheritance with the use of an in silico annotation prediction tool, we successfully narrowed down the candidates to the compound heterozygous mutations in the ABCG5 gene (c.1256G>A or p.Arg419His/c.1763-1G>A [splice acceptor site]) and to the double-compound heterozygous mutations in the MEFV gene (c.329T>C/C or p.Leu110Pro/c.442G>C/C or p.Glu148Val). The patient was genetically diagnosed with sitosterolemia and familial Mediterranean fever using WES for the first time. Such a comprehensive approach is useful for identifying causative mutations for multiple unrelated inheritable diseases.
