Abstract
Abstract
Background: T790M mutation in EGFR accounts for nearly 50% of the acquired mechanism of resistance to EGFR-tyrosine kinase inhibitors (TKIs). Previous studies suggested that EGFR T790M mutation was also detected in a considerable number of EGFR-TKI-naïve non-small-cell lung cancer (NSCLC) patients utilizing ultrasensitive detection methods such as droplet digital PCR (ddPCR). Here we investigated the significance of low-frequency pretreatment EGFR T790M mutation (preT790M) and its association with cancer molecular heterogeneity in the efficacy of EGFR-TKIs.
Materials and methods: Fifty-two advanced NSCLC patients harboring activating EGFR mutations treated with first-line EGFR-TKIs at Osaka City University Hospital between August 2013 and July 2016 were enrolled in the study. DNAs from tumor biopsies at diagnosis were available from 44 patients for detecting preT790M by the cobas® EGFR Mutation Test v2 (cobas) and ddPCR (RainDance Technologies) and those from 33 were available for assessing the actionable mutations in 50 genes by next-generation sequencing (NGS). NGS was performed on the Ion PGM using Ion AmpliSeq Cancer Hotspot Panel v2 (Life Technologies). Paired biopsies before EGFR-TKIs treatment and at disease progression (PD) were obtained from 15 patients to assess the T790M mutation by cobas.
Results: The overall detection rate of preT790M by ddPCR was 40.9% (18/44), while not detected in any case by cobas. The median progression free survival (mPFS) was 10.0 months for the patients with preT790M and 13.5 months for those without preT790M (p=0.288), respectively. When divided into 3 categories based on the frequency of preT790M such as high with T790M allele frequency (AF) >0.3%, low with AF ≤0.3% and undetected, 12 patients with high AF had a relatively shorter mPFS than 6 with low AF (p=0.090) and 26 without detectable preT790M (p=0.046) (7.7 vs 17.1 vs 13.5 months, respectively). NGS revealed 18 additional coexisting actionable mutations in 15 out of 33 patients: TP53 (n=7), PIK3CA (n=5), CTNNB1 (n=3) and uncommon EGFR (n=3). There was a trend for patients with higher preT790M AF to harbor less additional coexisting mutations (27% with high AF, 60% with low AF and 53% without preT790M, p=0.320). In 15 paired biopsies, T790M mutation was detected in 60% (9/15) at PD by cobas in the clinical setting; 67% (2/3) with high AF, 50% (1/2) with low AF and 60% (6/10) without detectable preT790M, suggesting T790M mutation after first-line EGFR-TKIs developed from both clonal selection and secondary acquisition models.
Conclusion: Results of our study indicated that EGFR-mutated NSCLCs with higher AF preT790M >0.3% had significantly shorter duration of response to EGFR-TKIs. In addition, the AF of preT790M in EGFR-mutated NSCLC may be associated with coexisting actionable mutation load potentially affecting the efficacy of EGFR-TKIs.

Abstract
Visceral leishmaniasis (VL) also known as kala-azar (KA) is the most severe form of leishmaniasis and can be fatal in the absence of treatment. KA is highly endemic in Mymensingh region of Bangladesh. Although estimating the true incidence of VL may be difficult. The objective of the study was to evaluate clinico-haematological parameters in different groups of leishmaniasis cases. It was a cross-sectional descriptive type of study and was conducted in a research centre of Mymensingh, Bangladesh from February 2016 to January 2017. A total of 90 cases who were rk-39 strip test positive from five divisions of Bangladesh admitted to Research Centre were included for clinical and haematological parameters. All the cases were categorized into five different groups depending on the clinical case definition and Real Time PCR (RT-PCR) was performed using buffy coat preparation. The age of the study subjects ranged from 3 to 80 years. Mymensingh was the highest affected division (60%) and primary kala azar (PKA) cases were more than half of the study subjects. Fever was the most common feature (100%) in PKA, relapse kala azar (R-KA) and treatment failure kala azar (TF-KA) followed by splenomegaly (70.2%) in PKA, loss of appetite (62.9%) in R-KA, and skin pigmentation was observed (100%) in PKDL cases. Anaemia was present in 62.7%, leucopenia in 57.6% and thrombocytopenia in 61.7% PKA cases. Pancytopenia was observed in a total of 33 cases from all groups. There were no significant changes in serum bilirubin, SGPT and serum creatinine level. RT-PCR was performed in all cases and found positive in 30 (63.8%) PKA, 16 (59.3%) R-KA, 2 (100%) TF-KA and 2 (50%) R-KA associated with PKDL cases. Overall, VL cases were positive in 62.5% (50/80) and no PKDL cases were detected by buffy-coat RT-PCR. In endemic areas, the magnitude of the problem and limited resources of a developing country like ours, clinical characteristics and hematological parameters may also play important role for diagnosis of the clinical cases.

Abstract
BACKGROUND Reversible cerebral vasoconstriction syndrome (RCVS) is a transient cerebrovascular disorder putatively caused by some immunosuppressive agents. CASE REPORT We recently encountered a 47-year-old female patient diagnosed with dilated cardiomyopathy who developed RCVS after heart transplantation. A triple-drug regimen consisting of tacrolimus, mycophenolate mofetil, and a corticosteroid was started after surgery. On postoperative day (POD) 11, the patient developed a severe headache, although computed tomography of the head demonstrated no signs of hemorrhage or infarction. At first, both a painkiller and migraine drugs were regularly administered to the patient. On POD 21, however, she developed an unbearable headache with a visual field defect and mild hemiparesis of the right hand. Magnetic resonance imaging (MRI) of the brain revealed a cerebral infarction in the left occipital lobe with diffuse vasoconstriction of both the middle and posterior cerebral arteries. A diagnosis of RCVS was made and tacrolimus, a drug suspected to cause RCVS, was discontinued. In its place, two doses of basiliximab followed by everolimus, both of which are alternatives for tacrolimus, were given. The corticosteroid dose was also increased. Furthermore, to release vasoconstriction, both verapamil and diltiazem were administered. On POD 27, cerebrovascular constrictions were shown to be relieved on brain MRI and the patient's neurological symptoms subsequently almost completely diminished. CONCLUSION RCVS should always be considered as a cause of headache in heart transplant recipients because tacrolimus, an immunosuppressive agent, may trigger RCVS. This will allow rapid intervention that is essential for avoiding irreversible neurological deficits.

Abstract
INTRODUCTION Tuberculous paradoxical reactions (PRs) are excessive immune reactions occurring after antituberculosis (TB) treatment and are commonly observed in immunocompromised hosts such as patients infected with the human immunodeficiency virus. CASE REPORT We recently encountered a 63-year-old male heart transplant recipient who developed tuberculous PR after treatment for miliary TB. The patient had been receiving immunosuppressive therapy with cyclosporine and mycophenolate mofetil for over 15 years. The diagnosis of miliary TB was made based on the presence of intermittent fever and fatigue; thus, anti-TB treatments (isoniazid, levofloxacin, ethambutol, and pyrazinamide) were started, which led to rapid defervescence and regression of the granular shadow and pleural effusion. However, a new persistent fever and confused state developed 1 month after the anti-TB therapy was started. After excluding possible etiologies of the patient's symptom, a PR was suspected, and anti-TB drugs were continued; corticosteroids were added as anti-inflammatory agents. After that, he has shown a favorable course with long-term anti-TB chemotherapy. CONCLUSION A PR should always be considered when the patients' symptoms of tuberculosis re-exacerbate after an appropriate anti-TB therapy. A PR commonly occurs in patients with various immunologic conditions including heart transplant recipients.

Abstract
BACKGROUND Left ventricular assist device (LVAD) therapy is the "gold standard" alternative therapy for patients with advanced heart failure. However, LVAD therapy is still uncommon in the Asia-Pacific region. Therefore, we aimed to elucidate the clinical outcomes of patients from Japan supported with the HeartMate II (HM-II) LVAD at our institution. METHODS Ninety-two patients (mean 44.3 ± 12.1 years, 68 men, average body mass index 1.65 ± 0.28 m2; 81 with nonischemic cardiomyopathy) who underwent HM-II implantation for bridge to transplantation (n = 91) or for destination therapy in a clinical study (n = 1) at the National Cerebral and Cardiovascular Center between April 2013 and October 2017 were enrolled in this analysis. Preoperatively, most patients (n = 73, 79%) had an INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) profile of between level 2 and 4. Postoperatively, the average pump speed was 8602 ± 258 rpm and the hemodynamics were well compensated. RESULTS Adverse events consisted of 38 (41.3%) hemolysis, 30 (32.6%) major infection, 27 (29.3%) major bleeding (6 [6.5%] with gastrointestinal bleeding), and 18 (19.6%) neurologic dysfunction events. Eighteen patients underwent heart transplantation (HTx) after an average of 32.9 ± 8.9 months of VAD support, and overall survival at both 6 months and 3 years was 96.3%. CONCLUSION Clinical outcome among patients with HM-II at our institution is satisfactory for both survival and adverse events. The HM-II can provide effective hemodynamic support during the extremely long waiting period for HTx in Japan.

Abstract
In recent years, an association between chronic kidney disease (CKD) and arteriosclerosis has been identified. Pulse pressure (PP) is used as an index of arteriosclerosis. However, there have been few studies of the relationship between PP and renal dysfunction in patients with CKD. Therefore, we examined the association of increased PP on renal function in patients with CKD and dyslipidemia. This study included 104 patients with CKD who were diagnosed with dyslipidemia and commenced on drug treatment. In the present study, patients with PP ≥65 mmHg were included in the High PP group, and patients with PP <65 mmHg were included in the Low PP group. We compared the High PP group with the Low PP group about background patient characteristics, laboratory data and antihypertensive medications and type. Mutiple logistic regression analysis identified estimated glomerular filtration rate (eGFR) as a significant predictor of PP ≥65 mmHg. In addition, values of BUN, Ccr, and eGFR baseline and 12 months later were compared. In the High PP group, compared with baseline, BUN increased significantly and Ccr and eGFR decreased significantly after 12 months later. We consider that PP may be an auxiliary indicator of generalized arterial sclerosis and renal function.

Abstract
We present a case of a woman with systemic lupus erythematosus (SLE) who had refractory episodes of neuromyelitis optica spectrum disorder (NMOSD) and was successfully treated with rituximab. She was positive for anti-aquaporin-4 (AQP4) antibody and had typical cranial and longitudinally extended spinal lesions but no optic nerve involvement. There is no established treatment for NMOSD/SLE overlap cases. Our experience suggests that rituximab may be effective for patients with combined SLE and anti-AQP4 antibody-positive NMOSD.

Abstract
Abstract
Background)
Sentinel lymph node (SLN) biopsy using indocyanine green fluorescence (fICG) method showed equal or better identification rate compared with blue dye or radioisotope (RI) method. In the fICG method, lymphatic vessels which drain into the SLNs can be seen through skin or subcutaneous tissue using near infrared camera (Photodynamic Eye®: PDE), and we can easily find the SLNs. However, whenever we observe the fluorescence images, we have to hold the PDE, turn off the operating light, and look at a monitor because fluorescence images cannot be seen directly. Medical imaging projection system (MIPS) is a new device which detects fluorescent emission from the organ and projects their images on the location of the fluorescence emission (Panasonic Connected Solutions Company, Japan). Projected images can be adjusted following the body movement or deformation of the organ. Therefore, MIPS could provide an option for real-time navigation for the SLN biopsy. The aim of this study was to evaluate the clinical utility of the MIPS.
Patients and methods)
Patients with clinically node-negative primary breast cancer underwent the fICG SLN biopsy using MIPS. Primary endpoint was identification rate of the fICG method using MIPS. At first, the study was conducted as an interventional study because the MIPS was the unapproved medical device. After approval of the MIPS, this study was conducted as an observational study. The study protocol was approved by the institutional review board at Kyoto University Hospital. All patients provided informed consent to participate in this study.
Results)
Between March 2016 and May 2017, 39 patients (40 procedures) underwent the fICG method SLN biopsy using MIPS. The median age was 55 years (range 32–74 years), and the median body mass index was 20.4 kg/m2 (range 17.7–27.7 kg/m2). About half had tumor stage T1 (58%) and 8 (20.0%) had DCIS. 8 procedures (20%) were performed after preoperative systemic therapy (PST). As MIPS itself can illuminate the operating field, SLN biopsy using MIPS was successfully performed without operating light in all procedures. At least one SLN was detected using MIPS for all procedures and the identification rate was 100% (95% CI: 91–100%). Median number of SLNs detected by MIPS was 3 (range 1–9) for all procedures, and 3 (range 2–8) for procedures after PST. Two pathologically positive SLNs and one SLN which included isolated tumor cells were detected by MIPS. In 25 procedures, RI was also used. 62 of 97 SLNs detected by MIPS (64%) were also detected by RI. However, no SLNs were detected only by RI.
Conclusions)
Although we still may not be able to avoid RI method because 25/40 (62.5%) procedures required the combined use of RI method, the fICG methods SLN biopsy using MIPS, which showed comparable identification rate of SLN with the conventional methods, could be useful tool with a view of allowing us to perform a real-time navigation surgery.

Abstract
We analysed the vascular morphology of the palm using a photoacoustic tomography (PAT) instrument with a hemispherical detector array. The three-dimensional (3D) morphology of blood vessels was determined noninvasively. Overall, 12 females and 11 males were recruited as healthy volunteers. Their ages were distributed almost evenly from 22 to 59 years. In all cases, many vascular networks were observed just beneath the skin and were determined to be veins anatomically. To analyse the major arteries, the layer containing the subcutaneous venous network was removed from the image. The analysis focused on the common and proper palmar digital arteries. We used the curvature of these arteries as a parameter to analyse their morphologies. There was no significant difference in the curvature between genders when comparing the subjects as a whole. The blood vessel curvature increased with age. Good agreement was found between the 3D numerical analysis results and the subjective evaluation of the two-dimensional (2D) projection image. The PAT system enabled visualization of the 3D features of blood vessels in the palm and noninvasive analysis of arterial tortuousness.

Abstract
Glioblastoma has the poorest prognosis, and is characterized by excessive invasion and angiogenesis. To determine the invasive mechanisms, we previously used two glioma cell lines (J3T-1 and J3T-2) with different invasive phenotypes. The J3T-1 showed abundant angiogenesis and tumor cell invasion around neovasculature, while J3T-2 showed diffuse cell infiltration into surrounding healthy parenchyma. Microarray analyses were used to identify invasion-related genes in J3T-2 cells, and the expressed genes and their intracellular and intratumoral distribution patterns were evaluated in J3T-2 cell lines, human glioma cell lines, human glioblastoma stem cells and human glioblastoma specimens. To determine the role of the invasion-related genes, invasive activities were evaluated in vitro and in vivo. Fibroblast growth factor 13 (FGF13) was overexpressed in J3T-2 cells compared to J3T-1 cells, and in human glioma cell lines, human glioblastoma stem cells and human glioblastoma specimens, when compared to that of normal human astrocytes. Immunohistochemical staining and the RNA-seq (sequencing) data from the IVY Glioblastoma Atlas Project showed FGF13 expression in glioma cells in the invasive edges of tumor specimens. Also, the intracellular distribution was mainly in the cytoplasm of tumor cells and colocalized with tubulin. Overexpression of FGF13 stabilized tubulin dynamics in vitro and knockdown of FGF13 decreased glioma invasion both in vitro and in vivo and prolonged overall survival of several xenograft models. FGF13 was negatively regulated by hypoxic condition. Silencing of FGF13 also decreased in vivo bevacizumab-induced glioma invasion. In conclusion, FGF13 regulated glioma cell invasion and bevacizumab-induced glioma invasion, and could be a novel target for glioma treatment.

Abstract
Recently, nanocarriers that transport bioactive substances to a target site in the body have attracted considerable attention and undergone rapid progression in terms of the state of the art. However, few nanocarriers can enter the brain via a systemic route through the blood-brain barrier (BBB) to efficiently reach neurons. Here we prepare a self-assembled supramolecular nanocarrier with a surface featuring properly configured glucose. The BBB crossing and brain accumulation of this nanocarrier are boosted by the rapid glycaemic increase after fasting and by the putative phenomenon of the highly expressed glucose transporter-1 (GLUT1) in brain capillary endothelial cells migrating from the luminal to the abluminal plasma membrane. The precisely controlled glucose density on the surface of the nanocarrier enables the regulation of its distribution within the brain, and thus is successfully optimized to increase the number of nanocarriers accumulating in neurons.There are only a few examples of nanocarriers that can transport bioactive substances across the blood-brain barrier. Here the authors show that by rapid glycaemic increase the accumulation of a glucosylated nanocarrier in the brain can be controlled.

Abstract
A 75-year-old man with stage IV lung adenocarcinoma was treated with osimertinib due to disease progression despite having been administered erlotinib. Both an epidermal growth factor receptor (EGFR) L858R mutation on exon 21 and a T790M mutation on exon 20 were detected in a specimen from a recurrent primary tumor. Five weeks after osimertinib initiation, he developed general fatigue and dyspnea. Chest computed tomography scan revealed diffuse ground glass opacities and consolidation on both lungs. An analysis of the bronchoalveolar lavage fluid revealed marked lymphocytosis, and a transbronchial lung biopsy specimen showed a thickened interstitium with fibrosis and prominent lymphocytic infiltration. We diagnosed the patient to have interstitial lung disease induced by osimertinib.

Abstract
Esophageal squamous cell carcinoma is a highly aggressive neoplasm and the sixth leading cause of global cancer-related death; the 5-year survival rate for esophageal cancer is only about 20%-25% for all stages. Therefore, improving the therapeutic effect is important. This study assessed whether low-dose hyperthermia (LDH) enhances the antitumor effects of chemotherapy. The antitumor effect of chemotherapy with/without LDH in the squamous cell carcinoma cell line SCCVII was evaluated. A comprehensive analysis was performed with real-time polymerase chain reaction (PCR) to study the hyperthermia-induced changes in the gene expression of SCCVII cell lines. In addition, the cytotoxic and apoptotic changes in the cells treated with LDH combined with/without 5-fluorouracil (5-FU) were measured. LDH combined with 5-FU (10 nM) strongly inhibited the cell growth of SCCVII, with flow cytometry showing an increased population of apoptotic cells. PCR showed that LDH promoted a 25.22-fold increase of p53 mRNA and 18.08-fold increase of Bax mRNA in vitro. MDR1 expression was decreased to 28.7% after LDH. This treatment can result in much higher efficacy of antitumor drugs. After LDH, the expressions of TS decreased to 12.06%, OPRT increased by 4.17-fold, and DPD did not change (1.03-fold). This transformations will induce susceptibility to 5-FU. LDH may be a useful enhancer of chemotherapy drugs for squamous cell carcinoma.

Abstract
We herein report an unusual case of Brodie's abscess of the radius in a child. A 13-year-old boy presented with pain on his right distal forearm. A plain radiograph showed an 8 cm translucent lesion in the distal radius. MRI showed a penumbra sign on the T1-weighted image, hyperintensity on T2-weighted images, and ring enhancement on the contrast-enhanced T1 image. 18F-FDG PET/CT images showed an uptake at the margin of the radius. Curettage and iliac cancellous bone grafting were undertaken for Brodie's abscess. Bacteriological examinations were found to be negative, however, the pathologic diagnosis showed chronic osteomyelitis. Eight months after surgery, the patient was asymptomatic and there was no sign of recurrence of infection. For Brodie's abscess in a child, thorough debridement is mandatory in addition to cancellous bone grafting. Brodie's abscess should be considered in the differential diagnosis of a patient who presents with forearm pain and exhibit the radiolucent osteolytic lesion on simple radiography.
