Abstract
BACKGROUND Although live-attenuated vaccines are contraindicated under immunosuppression, the immune status of patients with inflammatory bowel disease (IBD) has not been fully assessed prior to immunosuppressive therapy. AIMS To investigate antiviral serostatus against viruses requiring live vaccines for prevention in IBD patients undergoing immunosuppressive therapy. METHODS This multicenter study included IBD patients who were aged <40 years and were treated with thiopurine monotherapy, molecular-targeted monotherapy, or combination therapy. Gender- and age-matched healthy subjects (HS) living in the same areas were included as control group. Antibody titers against measles, rubella, mumps, and varicella were measured by enzyme-linked immunosorbent assays. RESULTS A total of 437 IBD patients (163 ulcerative colitis [UC] and 274 Crohn's disease [CD]) and 225 HS were included in the final analysis. Compared with HS, IBD patients had lower seropositivity rates for measles (IBD vs. HS = 83.91% vs. 85.33%), rubella (77.55% vs. 84.89%), mumps (37.50% vs. 37.78%), and varicella (91.26% vs. 96.44%). Gender- and age-adjusted seropositivity rates were lower in UC patients than in both CD patients and HS for measles (UC, CD, and HS = 81.60%, 85.29%, and 85.33%), rubella (76.40%, 78.23%, and 84.89%), mumps (27.16%, 43.70%, and 37.78%), and varicella (90.80%, 91.54%, and 96.44%); the difference was significant for all viruses except measles. Divided by the degree of immunosuppression, there were no significant differences in seropositivity rates among IBD patients. CONCLUSIONS IBD patients, especially those with UC, exhibit reduced seropositivity rates and may benefit from screening prior to the initiation of immunosuppressive therapy.

Abstract
BACKGROUND AND AIM The usefulness of fecal calprotectin (FC) and serum leucine-rich alpha-2 glycoprotein (LRG) assessing the activity of Crohn's disease (CD) remains to be fully demonstrated in Asia. The present study aimed to elucidate whether FC and LRG could predict endoscopic remission (ER) in Japanese patients with CD. METHODS Between October 2018 and July 2021, we prospectively observed treatment courses of CD patients treated with biologic agents. The optimal cutoff values of Crohn's Disease Activity Index (CDAI), serum C-reactive protein (CRP), serum albumin (Alb), FC, and LRG levels for predicting ER at week 52 were calculated using receiver operating characteristic (ROC) curves. We also analyzed the correlations between the achievement of clinical remission (CR) or biomarker remission (BR) at week 12/24/52 and ER at week 52. RESULTS Among 53 patients who completed 52 weeks of observation, 20 (37.7%) achieved ER at week 52. Using the calculated cutoff values, patients who achieved CR (CDAI ≤ 112) or BR (CRP ≤ 0.42 mg/dL, Alb ≥ 3.8 g/dL, FC ≤ 287 μg/g, or LRG ≤ 13.6 μg/mL) at week 12/24/52 had a higher ER rate at week 52. FC-BR at week 12/24 showed low sensitivity (0.58/0.60) but high specificity (0.78/0.74) for predicting ER; LRG-BR at week 12/24 also showed low sensitivity (0.68/0.74) but high specificity (0.87/0.78). However, FC-BR and LRG-BR at week 52 had improved sensitivity (0.80/0.84) while specificity remained (0.79/0.85). CONCLUSIONS From the early phase of biologic treatment, both FC and LRG had high specificity for predicting ER at week 52. LRG showed higher sensitivity than FC.

Abstract
OBJECTIVE Stress is thought to be one of the triggers of relapses in patients with inflammatory bowel disease (IBD). We examined the rate of relapse in IBD patients before and after the Great East Japan Earthquake. DESIGN A retrospective cohort study. SETTINGS 13 hospitals in Japan. PARTICIPANTS 546 ulcerative colitis (UC) and 357 Crohn's disease (CD) patients who received outpatient and inpatient care at 13 hospitals located in the area that were seriously damaged by the earthquake. Data on patient's clinical characteristics, disease activity and deleterious effects of the earthquake were obtained from questionnaires and hospital records. PRIMARY OUTCOME We evaluated the relapse rate (from inactive to active) across two consecutive months before and two consecutive months after the earthquake. In this study, we defined 'active' as conditions with a partial Mayo score=2 or more (UC) or a Harvey-Bradshaw index=6 or more (CD). RESULTS Among the UC patients, disease was active in 167 patients and inactive in 379 patients before the earthquake. After the earthquake, the activity scores increased significantly (p<0.0001). A total of 86 patients relapsed (relapse rate=15.8%). The relapse rate was about twice that of the corresponding period in the previous year. Among the CD patients, 86 patients had active disease and 271 had inactive disease before the earthquake. After the earthquake, the activity indices changed little. A total of 25 patients experienced a relapse (relapse rate=7%). The relapse rate did not differ from that of the corresponding period in the previous year. Multivariate analyses revealed that UC, changes in dietary oral intake and anxiety about family finances were associated with the relapse. CONCLUSIONS Life-event stress induced by the Great East Japan Earthquake was associated with relapse in UC but not CD.

Abstract
A 90-year-old woman was admitted to our hospital because of dizziness, without any remarkable abdominal symptoms. Severe anemia was found and thus gastrointestinal investigations were performed. CT and ultrasonography showed the specific multiplex layer configuration at the anal side of the descending colon. Colonoscopy showed a round tumor occupying the lumen and a consecutive gastrografin enema showed a crab-claw-like area without filling in the descending colon. Intussusception of the colon was diagnosed and partial resection of the descending colon was performed, but without relief of intussusception. The tumor was histologically diagnosed as mucinous adenocarcinoma. By various factors, incomplete fixation between the retroperitoneum and the descending colon might result in the present condition.

Abstract
The morphological identification of immature oocytes has commonly been used to select the bovine oocytes for IVF. However, <30% of the recovered oocytes reach the blastocyst stage after fertilization, and this is probably due to the quality of the oocytes at the beginning of maturation. The brilliant cresyl blue (BCB) stain determines the activity of glucose-6-phosphate dehydrogenase, an enzyme synthesized in growing oocytes. The aim of this study was to evaluate the effect of the BCB stain on the selection of bovine oocytes and on the subsequent embryo development for in vitro production (IVP). Cumulus–oocyte complexes (COCs) were collected by the aspiration of 2- to 6-mm follicles. A total of 559 oocytes were divided into 2 groups: (1) a control group, immediately cultured, and (2) a BCB-incubated group. After 90 min of BCB staining (Pujol et al. 2004 Theriogenology 61, 735–744), the oocytes were divided into oocytes with blue cytoplasm (BCB+) and oocytes without blue cytoplasm (BCB−). The COCs were matured for 20 h in TCM-199 supplemented with 5% calf serum (CS) and 0.02 mg mL−1 FSH at 38.5°C under an atmosphere of 5% CO2 in air. The matured COCs were inseminated with 5 × 106 sperm mL−1. After 18 h of gamete co-culture, the presumed zygotes were cultured in CR1aa supplemented with 5% CS for 9 days at 38.5°C under an atmosphere of 5% CO2, 5% O2, and 90% N2. Embryonic development was evaluated at 48 h after IVF (proportion of ≥5-cell stage, the total cleavage rates) and on Days 7 to 9 (blastocyst rate). The experiment was replicated 5 times, and the data were analyzed by a chi-square test and ANOVA. The results are presented in Table 1. The proportion of embryos with ≥5-cell stage was significantly higher (P < 0.01) in the BCB+ group than in the BCB− group, but not in the control group. The total cleavage rate for the BCB+ embryos was significantly higher than that of either the BCB− or the control group (P < 0.01). There were also significant differences (P < 0.01) in the blastocyst development between the BCB+ and BCB− embryos and between the BCB− and the control embryos (P < 0.05). This result showed that the selection of bovine oocytes by BCB staining before in vitro maturation may be useful for selecting oocytes that are developmentally competent up to Day 9 for IVP.

Abstract
OBJECTIVE Population-specific differences in the genetic susceptibility to inflammatory bowel disease (IBD) are indicated by the fact that Crohn's disease (CD) in Japanese patients does not have any of the common CARD15 variants that are associated with CD in Caucasians. Recently, the disease-causing mutation in the IBD5 haplotype was identified. The TC haplotype, composed of L503F in SLC22A4 and -207G/C in SLC22A5 promoters, was reported to alter the function of the organic cation transporter and to be associated with CD in Caucasians. To determine whether the TC haplotype is also associated with IBD in a Japanese population, we genotyped L503F and -207G/C variants in Japanese subjects. Furthermore, we also performed a case-control association study with all representative single nucleotide polymorphisms (SNPs) in IBD5 using previous information of linkage disequilibrium extension reported in Japanese patients to determine whether there were variants in IBD5 specifically associated with IBD in Japanese patients. MATERIAL AND METHODS A total of 758 Japanese individuals, 241 patients with CD, 247 patients with ulcerative colitis (UC) and 270 healthy controls, were analyzed in this study. Genotyping for SNPs was determined by polymerase chain reaction-restriction fragment length polymorphism analysis. RESULTS We found L503F and -207G/C to be very rare (<1% frequency) in CD, UC and HC in the Japanese population. Furthermore, we also found that none of the representative SNPs in IBD5 was associated with CD or UC in the Japanese subjects. CONCLUSIONS In contrast to Caucasians, IBD5 is not a major component of the susceptibility to IBD in the Japanese population.

Abstract
BACKGROUND AND STUDY AIMS Patients with intestinal graft-versus-host disease (GVHD) are generally in poor clinical condition. In this study we aimed to establish the clinical significance of endoscopic diagnosis of this condition, observing only the distal section of the large intestine. PATIENTS AND METHODS Endoscopic and pathological findings at colonoscopy were evaluated retrospectively in 12 patients who were diagnosed with intestinal GVHD after undergoing hematopoietic stem cell transplantation. RESULTS The main mucosal changes observed at endoscopy were granular change, edema, "spotty redness", and sloughing. These were clearly displayed after enhancement with Indigo carmine staining, and with insertion of the colonoscope only as far as the distal section of the large intestine. A histological diagnosis of intestinal GVHD was made in 50 % of the patients, whose intestinal epithelium specimens showed numerous apoptotic bodies. It was possible to perform total colonoscopy in two patients who were in relatively good condition clinically, but there were no remarkable differences in the endoscopic findings throughout the large intestine, from the terminal ileum to the rectum. In terms of clinical outcomes of the 12 patients, their prognosis was poor in that they all either went on to suffer from chronic GVHD or died. CONCLUSIONS Endoscopic and histological findings on distal colonoscopy are clinically significant in the diagnosis of intestinal GVHD, and limiting this examination to the distal section of the large intestine avoids causing further clinical deterioration in patients who are already in very poor general condition and the possibility of causing endoscopy-related complications.

Abstract
Ulcerative colitis (UC) is a multifactorial disorder with both genetic and environmental factors. HLA-B*52 and DRB1*1502 are reported to be strongly associated with UC in Japan. However, the actual susceptible gene has not been identified yet. In this study, to map precisely the susceptible locus for UC, we performed association mapping in the chromosome 6p using 24 microsatellite markers distributed over 16 Mb. A total of 183 patients with UC and 186 healthy controls (HC) were included in this study. In all, 15 markers around the human leukocyte antigen (HLA) region showed statistical significance in the genotypic differentiation test concerned with the allelic distribution between the UC and HC. Especially, the markers between the centromeric region of HLA class I and the telomeric region of class III showed remarkably low P-values and the allele239 of C2-4-4 in class I marker showed the strongest association (Pc=2.9 x 10(-9): OR=3.74, 95% CI=2.50-5.60). Furthermore, we found strong linkage disequilibrium (LD) between the allele239 of C2-4-4 and HLA-B*52 in haplotype analysis. These results provide evidence that, in Japanese, important determinants of disease susceptibility to UC may exist in HLA, especially between the centromeric region of class I and the telomeric region of class III, under the strong LD with HLA-B*52.

Abstract
BACKGROUND The diagnosis of mucosa-associated lymphoid tissue (MALT) lymphoma in the intestine is occasionally difficult from histological examination on small biopsy specimens obtained by endoscopy. This study focused on unusual cases of reactive lymphoproliferative disorders in the intestine in order to make a differential diagnosis of MALT lymphoma. MATERIALS AND METHODS Five patients were examined with regards to clinical symptoms, endoscopic findings and multiparameter analysis (the morphological examination using routine hematoxylin and eosin staining by light microscopy, immunophenotyping by flow cytometry (FCM), immunohistochemistry and genotyping of extracted DNA). RESULTS All cases showed an aggregation of lymphocytes and one case showed similar features to lymphoepithelial lesions. Analyses of FCM and genetic rearrangements denied the monoclonality in all cases. Consequently, we considered that all cases should be diagnosed as reactive lymphoid hyperplasia and inflammatory change. CONCLUSION Multiparameter analysis is useful in making an exact diagnosis of MALT lymphoma and therefore contributes to prevent unnecessary overtreatment.

Abstract
In few cases of Turner syndrome the karyotype reveals the presence of an additional Y-bearing cell line, which is referred to as a borderline case of mixed gonadal dysgenesis. We report a 20-year-old woman with primary amenorrhea, virilization and a few Turner stigmata, who revealed rare mosaicism of 45,X/46,X dic (Y; 5)(q12; q11), +5/46,X, der (Y), which was detected by conventional G-banding and multicolor spectral karyotyping. She underwent laparoscopic gonadectomy in which mixed gonadal dysgenesis was found and both gonads were removed. No evidence of gonadoblastoma was noted on the gonads. Virilization improved postoperatively. We recommend gonadectomy via laparoscope in women presenting with Turner-like phenotype, virilization and the presence of a Y chromosome. This report describes the role of cytogenetic and molecular genetic investigations in the definition of mosaicism in Turner syndrome.

Abstract
The effect of segmental transcatheter arterial chemoembolization (TAE) on serum amino acid levels and liver function were studied in 23 patients with HCC associated with hepatitis virus C (22 patients) or alcoholism (1 patient), with compensated liver cirrhosis (Child A 18 patients, Child B 5 patients). Serum levels of branched-chain amino acids (BCAA), tyrosine, branched-chain amino acids to tyrosine ratio (BTR), ammonia, total bilirubin and albumin, and prothrombin times were measured before and after TAE (24 h, 7 and 14 days). The BTR was increased significantly 24 h after TAE (p<0.001) and gradually decreased to pre-TAE levels. Serum tyrosine levels decreased at 24 h after TAE (p<0.005) and later increased. Serum BCAA levels increased slightly at 7days after TAE and were decreased at 14 days after TAE. This results indicated that the increased BTR was due primarily to the decreased tyrosine level at 24 h after TAE. Serum ammonia levels gradually decreased after TAE and the prothrombin time and serum levels of total bilirubin and albumin were not significantly changed. In this study, segmental TAE had little influence on liver function, and the BTR unexpectedly increased at 24 h after TAE. These results suggest that segmental TAE has minimal side effects and may have a beneficial effect on amino acid metabolism.

Abstract
OBJECTIVE To investigate the usefulness of ultrasonography (USG) and magnetic resonance imaging (MRI) in the early diagnosis of interstitial pregnancy. STUDY DESIGN Four cases of interstitial pregnancy that showed characteristic ultrasonographic and MRI findings were studied. All cases received cornual resection, and the presence of interstitial pregnancy was confirmed by pathologic examination. RESULTS Three of four cases had a gestational sac in the uterine cornu or a protruding cornual mass and myometrium between the sac and uterine cavity on both USG and MRI. In the remaining case, preoperative diagnosis was inconclusive because no gestational sac was demonstrated by USG or MRI. Color flow mapping was conducted in three cases and revealed prominent peritrophoblastic blood flow. CONCLUSION The findings suggest that USG combined with color flow mapping is the first choice in the early diagnosis of interstitial pregnancy. MRI, which is an extremely expensive imaging technology, should be used only if transvaginal USG with color flow mapping is inconclusive in ruling out the diagnosis of interstitial pregnancy.

Abstract
A 37-year-old male visited our hospital complaining of right scrotal mass formation. An elastic hard, fist-size mass was found in the right scrotum. Under the diagnosis of an intrascrotal benign tumor, the mass was removed. The tumor had no relation to the testis or epididymis. The surgical specimen weighted 220 g and measured 13 x 8 x 8 cm in size. Histopathological diagnosis was epidermal cyst of the intrascrotum. Epidermal cyst of the intrascrotum is a rare disease and only 13 cases have been previously reported in Japan.

Abstract
The development of the pecten oculi, a structure peculiar to the avian eye, was studied by scanning electron microscopy (SEM) correlated with light microscopy (LM) in embryonic and adult chickens. The development of the chick pecten was divided into 4 phases: (1) formation of the primordial pecten (Hamburger-Hamilton's stages 27 to 29), (2) formation of the plate-like pecten (stages 30 to 34), (3) pleat formation and pigmentation (stages 35 to 37), and (4) bridge formation and high-vascularization (stage 38 to adult). The primordial pecten is formed entirely from the ectoderm by fusion of the inwardly-projecting edges of the optic fissure. The primordial pecten grows into a tall, thin plate rising from a broad base. The pecten begins to fold slightly at stage 35. The number of pleats increases rapidly, from 7 at stage 35, to 16 at stage 36, 18 at stage 37, and 19 to 20 at stage 40. The bridge begins to form at stage 38 by a swelling of the apical edge of the pecten and completes its development by the twentieth post-hatch day. Blood vessels appear first in the broad base of the plate-like pecten, then become more numerous and gradually extend into the pleats. The pecten becomes more vascular than cellular at stage 43, and it is highly vascularized in the adult. The pleat surface becomes conspicuously irregular with increased vascularization. The peripectinate cells, located on the pecten, are already present at stage 27.
