Abstract
Gluten ataxia, a type of cerebellar ataxia caused by exposure to gluten in sensitive patients, has been considered common in the USA and Europe, and rare in Asia. We measured anti-deamidated gliadin peptide (DGP) antibody levels in 49 patients with cerebellar ataxia, excluding those with multiple system atrophy, hereditary spinocerebellar ataxia, or cancer, as well as those who were receiving oral administration of phenytoin. Anti-DGP antibody was positive in eight (16.3 %) patients, five of these patients were positive only for IgA, one was positive for both IgG and IgA, and two were positive only for IgG antibody. Intravenous immunoglobulin was administered to five of the eight patients, and was markedly effective in one, moderately effective in two, and ineffective in two. Steroid therapy was administered to four patients, but none had an apparent response. Ataxia symptoms improved in one patient treated with a gluten-free diet only. Although it had been thought to be extremely rare in Asia, we speculate that more than 10 % of cerebellar ataxia patients in Japan currently have gluten ataxia; therefore, measuring anti-DGP antibody or anti-gliadin antibody in cerebellar ataxia patients in Asia is important.

Abstract
47 renal biopsies from 36 patients with SLE were examined in detail to compare with clinical courses and ultrastructural findings. Of 36 patients, 8 cases were free from renal involvement. The severity of electron dense deposits in glomeruli with lupus nephritis were generally well correlated with each clinical feature obtained. Moreover, mesangiocapillary cell proliferation was considered to be the main morphological promoting factor in poor prognosis of the lupus nephritis. Prominent circumferential subendothelial dense deposits were suggested to enhance to enhance the proliferation of mesangial cells, mostly with a mode of circumferential interposition. In each deposit with lapse of time and/or treatments, subepithelial deposits were gradually degraded to granular material but not lucent, though most subendothelial deposits rapidly disappeared without any remnant structure or with only a few flocculent materials. Mesangial deposits were mostly stabilized and rarely turned membranous.

Abstract
Background: Bilateral Wilms tumours (BWTs) occur by germline mutation of various predisposing genes; one of which is WT1 whose abnormality was reported in 17–38% of BWTs in Caucasians, whereas no such studies have been conducted in East-Asians. Carriers with WT1 mutations are increasing because of improved survival. Methods: Statuses of WT1 and IGF2 were examined in 45 BWTs from 31 patients with WT1 sequencing and SNP array-based genomic analyses. The penetrance rates were estimated in WT1-mutant familial Wilms tumours collected from the present and previous studies. Results: We detected WT1 abnormalities in 25 (81%) of 31 patients and two families, which were included in the penetrance rate analysis of familial Wilms tumour. Of 35 BWTs from the 25 patients, 31 had small homozygous WT1 mutations and uniparental disomy of IGF2, while 4 had large 11p13 deletions with the retention of 11p heterozygosity. The penetrance rate was 100% if children inherited small WT1 mutations from their fathers, and 67% if inherited the mutations from their mothers, or inherited or had de novo 11p13 deletions irrespective of parental origin (P=0.057). Conclusions: The high incidence of WT1 abnormalities in Japanese BWTs sharply contrasts with the lower incidence in Caucasian counterparts, and the penetrance rates should be clarified for genetic counselling of survivors with WT1 mutations.

Abstract
INTRODUCTION Changes in the biological marker status between primary and recurrent tumors are observed in breast cancer. However, their clinical significance is still uncertain, especially for patients with ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery. PATIENTS AND METHODS A total of 117 patients with IBTR without distant metastases were enrolled in this study. All patients were examined for estrogen receptor (ER), HER2, and Ki-67 in both the primary tumors and paired IBTR. We evaluated the impact of changes in these biomarkers between primary tumors and IBTR on the prognosis after IBTR. RESULTS There were no associations of changes in the ER, HER2 status with distant disease-free survival (DDFS) after surgical resection of IBTR, whereas the change in the Ki-67 status between the primary tumors and IBTR was significantly correlated with DDFS (unadjusted: p = 0.0094; adjusted: p = 0.013). Patients in the "increased or remained high" Ki-67 group had a significantly shorter DDFS than those in the "decreased or remained low" Ki-67 group (5-year DDFS: 55.5 vs. 79.3%, respectively, p = 0.0084 by log-rank test). CONCLUSION An increased or persistently high Ki-67 status in the IBTR was significantly correlated with a poorer prognosis after IBTR.

Abstract
OBJECTIVES To evaluate neonatal outcomes and clinical characteristics of monochorionic diamniotic (MCDA) twins with a large intertwin hemoglobin (Hb) difference at birth. METHODS This was a retrospective cohort study of MCDA twin gestations delivered at Osaka Medical Center and Research Institute for Maternal and Child Health between 2003 and 2012. Cases of pregnancy termination, acardiac twins or intrauterine death were excluded. A large intertwin Hb difference at birth was defined as > 8.0 g/dL according to the postnatal criteria for twin anemia-polycythemia sequence (TAPS). The intertwin reticulocyte count ratio (RCR) was calculated by dividing the reticulocyte count of the anemic twin by that of the polycythemic twin. Cases with Hb differences were divided into two groups according to the RCR, TAPS when the RCR was > 1.7 and acute fetofetal hemorrhage (AFFH) when the RCR was ≤ 1.7. Neonatal outcomes were compared between the TAPS and AFFH groups. RESULTS During the study period, 432 MCDA twin pregnancies of a total of 532 born at our hospital were analyzed. There were 12 (2.8%) cases of a large intertwin Hb difference. The median gestational age at birth of these cases was 34 (range, 23-38) weeks, and all were delivered by Cesarean section. There were seven (1.6%) cases of TAPS and five (1.2%) of AFFH. The neonatal survival rate was 91.7%; in one pair of twins with TAPS neonatal death occurred. All (100%) cases with TAPS and two (40%) with AFFH required blood transfusion or partial-exchange transfusion for at least one infant. CONCLUSIONS Although the incidence of TAPS and AFFH may be low in MCDA twins, many affected neonates required treatment for hematological abnormalities. Delivery of MCDA twins via Cesarean section does not appear to prevent AFFH, despite the absence of labor.

Abstract
We evaluated atrophic sites in the brainstem and cerebellum in the patients with spinocerebellar degeneration by using voxel-based morphometry (VBM). Gray matter atrophy was found extensively in both the cerebellar hemispheres and vermis of subjects presenting the cerebellar variant of multiple system atrophy (MSA-C; n=9). In addition, remarkable white matter atrophy was observed in the middle cerebellar peduncle, brainstem, and cerebellar hemispheres. In contrast, gray matter atrophy was not apparent in the cerebellar hemispheres or vermis of subjects in the SCA3 group (n=6), whereas intense white matter atrophy was visible in the middle cerebellar peduncle, brainstem, and cerebellar hemispheres. White matter atrophy was also observed in the brainstem and surrounding the dentate nucleus in both cases of dentatorubral-pallidoluysian atrophy (DRPLA) (n=2), whereas gray matter atrophy of the cerebellum was not remarkable. In both the SCA6 group (n=3) and the SCA31 group (n=2), gray matter atrophy was prominent in the cerebellar hemispheres and vermis; however, white matter atrophy was not found in the middle cerebellar peduncle and brainstem, whereas symmetric atrophy of white matter was found in the vicinity of the dentate nucleus. In each of these diseases, VBM findings were consistent with the pathological findings; therefore, VBM can be considered a useful tool for the diagnosis of spinocerebellar degeneration.

Abstract
Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease with exacerbations involving recurrent or bilateral optic neuritis and longitudinally extensive transverse myelitis. Pulse steroid therapy is recommended as the initial, acute-phase treatment for NMO. If ineffective, treatment with plasma exchange (PE) should commence. However, no evidence exists to support the effectiveness of PE long after the acute phase. Immunoadsorption therapy (IA) eliminates pathogenic antibodies while sparing other plasma proteins. With IA, side effects of PE resulting from protein substitution can be avoided. However, whether IA is effective for NMO remains unclear. We describe a patient with anti-aquaporin-4-positive myelitis who responded to IA using a tryptophan polyvinyl alcohol gel column that was begun 52 days after disease onset following the acute phase. Even long after the acute phase when symptoms appear to be stable, IA may be effective and should not be excluded as a treatment choice.

Abstract
In this study, the feeding behaviour of the non-native invasive predatory fishes largemouth bass Micropterus salmoides and bluegill Lepomis macrochirus was studied in the Ezura River, a northern tributary of Lake Biwa, Japan. Prey composition was estimated based on visual examination of stomach contents and faecal DNA analysis to determine feeding habits of these predatory fishes. Stomach content analysis showed that native fishes (e.g. ayu Plecoglossus altivelis and gobies Rhinogobius spp.) and shrimps (e.g. Palaemon paucidens) were the major prey items for M. salmoides, while snails, larval Chironomidae and submerged macrophytes were the dominant prey items of L. macrochirus. Micropterus salmoides tended to select larger fish in the case of crucian carp Carassius spp., but smaller fishes in the case of P. altivelis and Rhinogobius spp. Faecal DNA analyses revealed prey compositions similar to those identified in predator stomach contents, and identified additional prey species not detected in stomach content inspection. This study demonstrated that both stomach content inspection and DNA-based analysis bear several inherent shortcomings and advantages. The former method is straightforward, although identification of species can be inaccurate or impossible, whereas the latter method allows for accurate species identification, but cannot distinguish prey size or stage. Hence, integration of morphology-based and DNA-based methods can provide more reliable estimates of foraging habits of predatory fishes.

Abstract
Background: Sentinel lymph node (SLN) biopsy guided by radioisotope (RI), blue dye or in combination methods is common. A high identification rate is reported for the RI-guided method. On the other hand, it has the demerits of radiation exposure, being expense, and it can only be used in a radiation-controlled area. The blue dye method, however, is safe and inexpensive, but the identification rate is lower compared with the RI method and requires training. The indocyanine green (ICG) fluorescent method involves the application of the fluorescing property. Lymph flow can be traced from outside the body with a photodynamic eye (PDE) camera simultaneously with an operation procedure. The ICG method is safe, inexpensive and requires little training, therefore its use will be widely permitted in any general hospitals. Recently, based on several retrospective clinical trials, the identification rate with the ICG fluorescent method has been reported to be equal to or greater than the RI method. The purpose of this multicenter study is to prospectively assess the diagnostic performance of SLN biopsy using the ICG fluorescence technique compared with RI.
Materials and methods: In this validation study, the patients aged from 20 to 75 years-old with operable primary invasive breast cancer (cT1c-2N0M0) have been nominated and required the written informed consent.
All candidates underwent SLN biopsy using the combined methods with RI and ICG fluorescence. The target sample size was 840 patients to evaluate the sensitivity of ICG method as a primary endpoint, and after 200 patients were enrolled we analyzed the identification rate and the SLN-positive rate of the RI and ICG methods respectively as the interim analysis planned beforehand.
Results: Two hundred eligible patients were enrolled in this study from May 2011 to February 2012. Their median age was 53.0 years (range: 27-74 years). The number of patients with cT1c was 106 and that with cT2 was 94. The identification rate of the RI and the ICG method was 97% (194/200) and 96% (192/200) respectively. Of the 194 patients that were identified with the RI method, 186 (95.9%) were also identified with the ICG method. ICG identified 6 patients that were not identified by RI. On the other hand, RI identified 8 patients that were not identified by ICG. The SLN-positive rate was 25.5% (51/200). This rate was higher than we expected. Of the 51 patients with positive metastatic lymph nodes, 23 patients (21.7%) had cT1c breast cancer and 28 (29.8%) had cT2 breast cancer. The positive rate of the first SLN was 23.5% (47/200) and tumor cells skipped to the second or further tier in four cases (2%).
Conclusions: The ICG-guided SLN biopsy procedure achieved a high identification rate almost equal to that with the RI method. Using this combination method, the identification rate was 100%. We will assess the sensitivity and the additive effect of combining the ICG fluorescence method with the RI method, etc., when all 840 patients have been enrolled (UMIN000005167).

Abstract
BACKGROUND The role of glial cell line-derived neurotrophic factor (GDNF) in pain and muscular nociceptor activities is not well understood. We examined pain-related behaviour and mechanical response of muscular thin-fibre afferents after intramuscular injection of GDNF in rats. METHODS GDNF and antagonist to transient receptor potential V1 or acid-sensing ion channels were injected into rat gastrocnemius muscle and muscular mechanical hyperalgesia was assessed with a Randall-Selitto analgesiometer. Activities of single C- (conduction velocity < 2.0 m/s) and Aδ-fibres (conduction velocity 2.0-12.0 m/s) were recorded from extensor digitorum longus muscle-nerve preparations in vitro. The changes in the responses to mechanical stimuli before and after GDNF injection were recorded. RESULTS Mechanical hyperalgesia was observed from 1 h to 1 day after GDNF (0.03 μM, 20 μL) injection. The decreased withdrawal threshold was temporarily reversed after intramuscular injection of amiloride (50 mM, 20 μL), but not capsazepine (50 μM, 20 μL). In single-fibre recordings, both phosphate buffered saline (PBS) and GDNF failed to induce any significant discharges. GDNF significantly enhanced the mechanical response when compared with the PBS group, but only in Aδ-fibre afferents. C-fibres were not affected. Significantly lowered threshold and increased response magnitude to mechanical stimuli were observed 30 or 60-120 min after injection. These times are compatible with the timing of the onset of the hyperalgesic effect of GDNF. CONCLUSIONS These results suggest that GDNF increased the response of muscular Aδ-fibre afferents to mechanical stimuli, resulting in muscular mechanical hyperalgesia.

Abstract
Renal carcinoid tumor is a rare neoplasm. In this article, we review this neoplasm with a focus on clinical and pathobiological aspects. The majority of patients present in the fourth to seventh decades, but there is no gender predilection. Clinically, patients with renal carcinoid tumor frequently present with abdominal, back or flank pain. This tumor is occassionally associated with horseshoe kidney and/or mature cystic teratoma located in the kidney. Macroscopically, these tumors are well demarcated with a lobulated appearance and yellow or tan-brown color cut surface. Microscopically, these tumors are composed of monomorphic round to polygonal cells with granular amphophilic to eosinophilic cytoplasm. Tumor cells are arranged in trabecular, ribbon-like, gyriform, insular, glandular and solid patterns. The nuclei are round to oval and with evenly distributed nuclear chromatin, frequently with a "salt and pepper"-pattern. Immunohistochemically, tumor cells demonstrate immuno-labeling for chromogranin A and synaptophysin. Ultrastructurally, the neoplastic cells contain abundant dense core neurosecretory granules. In previous genetic studies, abnormalities of chromosomes 3 or 13 have been reported. The clinical behavior of renal carcinoid tumors is variable, but is more indolent than most renal cell carcinomas. Further investigations are warranted in order to elucidate the critical genetic abnormalities responsible for the pathogenesis of this rare entity in renal neoplastic pathology.
