Abstract
BACKGROUND AND PURPOSE With the increasing use of the Pipeline Embolization Device for the treatment of aneurysms, predictors of clinical and angiographic outcomes are needed. This study aimed to identify predictors of incomplete occlusion at last angiographic follow-up. MATERIALS AND METHODS In our retrospective, single-center cohort study, 105 ICA aneurysms in 89 subjects were treated with Pipeline Embolization Devices. Patients were followed per standardized protocol. Clinical and angiographic outcomes were analyzed. We introduced a new morphologic classification based on the included angle of the parent artery against the neck location: outer convexity type (included angle, <160°), inner convexity type (included angle, >200°), and lateral wall type (160° ≤ included angle ≤200°). This classification reflects the metal coverage rate and flow dynamics. RESULTS Imaging data were acquired in 95.3% of aneurysms persistent at 6 months. Complete occlusion was achieved in 70.5%, and incomplete occlusion, in 29.5% at last follow-up. Multivariable regression analysis revealed that 60 years of age or older (OR, 5.70; P = .001), aneurysms with the branching artery from the dome (OR, 10.56; P = .002), fusiform aneurysms (OR, 10.2; P = .009), and outer convexity-type saccular aneurysms (versus inner convexity type: OR, 30.3; P < .001; versus lateral wall type: OR, 9.71; P = .001) were independently associated with a higher rate of incomplete occlusion at the last follow-up. No permanent neurologic deficits or rupture were observed in the follow-up period. CONCLUSIONS The aneurysm neck located on the outer convexity is a new, incomplete occlusion predictor, joining older age, fusiform aneurysms, and aneurysms with the branching artery from the dome. No permanent neurologic deficits or rupture was observed in the follow-up, even with incomplete occlusion.

Abstract
BACKGROUND AND PURPOSE Recanalization after coil embolization is widely studied. However, there are limited data on how recanalized aneurysms rupture. Herein, we describe our experience with the rupture of recanalized aneurysms and discuss the type of recanalized aneurysms at greatest rupture risk. MATERIALS AND METHODS A total of 426 unruptured aneurysms and 169 ruptured aneurysms underwent coil embolization in our institution between January 2009 and December 2017. Recanalization occurred in 38 (8.9%) of 426 unruptured aneurysms (unruptured group) and 37 (21.9%) of 169 ruptured aneurysms (ruptured group). The Modified Raymond-Roy classification on DSA was used to categorize the recanalization type. Follow-up DSA was scheduled until 6 months after treatment, and follow-up MRA was scheduled yearly. If recanalization was suspected on MRA, DSA was performed. RESULTS In the unruptured group, the median follow-up term was 74.0 months. Retreatment for recanalization was performed in 18 aneurysms. Four of 20 untreated recanalized aneurysms (0.94% of total coiled aneurysms) ruptured. In untreated recanalized aneurysms, class IIIb aneurysms ruptured significantly more frequently than class II and IIIa (P = .025). In the ruptured group, the median follow-up term was 28.0 months. Retreatment for recanalization was performed in 16 aneurysms. Four of 21 untreated recanalized aneurysms (2.37% of total coiled aneurysms) ruptured. Class IIIb aneurysms ruptured significantly more frequently than class II and IIIa (P = .02). CONCLUSIONS The types of recanalization after coil embolization may be predictors of rupture. Coiled aneurysms with class IIIb recanalization should undergo early retreatment because of an increased rupture risk.

Abstract
Endoscopic submucosal dissection (ESD) is an accepted standard treatment for early gastric cancer but is not widely used in the esophagus because of technical difficulties. To increase the safety of esophageal ESD, we used a scissors-type device called the stag beetle (SB) knife. The aim of this study was to determine the efficacy and safety of ESD using the SB knife. We performed a single-center retrospective, uncontrolled trial. A total of 38 lesions were excised by ESD from 35 consecutive patients who were retrospectively divided into the following two groups according to the type of knife used to perform ESD: the hook knife (hook group) was used in 20 patients (21 lesions), and the SB knife (SB group) was used in 15 patients (17 lesions). We evaluated and compared the operative time, lesion size, en bloc resection rate, pathological margins free rate, and complication rate in both groups. The operative time was shorter in the SB group (median 70.0 minutes [interquartile range, 47.5-87.0]) than in the hook group (92.0 minutes [interquartile range, 63.0-114.0]) (P = 0.019), and the rate of complications in the SB group was 0% compared with 45.0% in the hook group (P = 0.004). However, the lesion size, en bloc resection rate, and pathological margins free rate did not differ significantly between the two groups. In conclusion, ESD using the SB knife was safer than that using a conventional knife for superficial esophageal neoplasms.

Abstract
565 Background: Polymorphisms in fragment C receptor (FcγR) are expected as a predictive biomarker of cetuximab (Cmab). Previous studies have convincingly confirmed the distributions (dists) of FcγR polymorphisms in Western population and shown the existence of linkage disequilibrium (LD) between FcγRIIa and FcγRIIIa polymorphisms. Meanwhile, the dists in Asian population have been unknown but a few studies for non-cancer patients have suggested the difference in dists between Asian and Western populations. We investigated the dists of FcγR polymorphisms and their association with clinical response to Cmab in Japanese mCRC patients. Methods: Ninety-three patients with irinotecan/oxaliplatin/5-FU-refractory mCRC and treated by Cmab plus irinotecan or Cmab monotherapy were retrospectively registered from 8 centers in Japan. FcγR polymorphisms were determined from genomic DNA extracted from peripheral blood samples based on the Multiplex allele-specific PCR method. Comparisons according to FcγR polymorphisms were evaluated using Fisher's exact test for response rate (RR) and log-rank test for progression-free survival curves (PFS). Results: The dists of FcγRIIa HH/HR/RR and FcγRIIIa VV/VF/FF were 68/30/2% and 4/40/56%, respectively (Table). The absence of LD between FcγRIIa and FcγRIIIa polymorphisms was confirmed (GENEPOP, p=0.526; Linkdis, p=0.146). Of 74 patients with KRAS wild-type and treated by Cmab plus irinotecan, no difference according to FcγR polymorphisms was observed in either RR (IIa: HH 37% vs. HR/RR 36%, p=1.00; IIIa: VV/VF 39% vs. FF 35%, p= 0.81) or PFS curves (IIa: HH vs. HR/RR, p=0.84; IIIa: VV/VF vs. FF, p=0.09). Similar results were seen in patients treated by cetuximab monotherapy. Conclusions: This study clarified an ethnic difference in the frequencies of FcγR polymorphisms. Associations between the polymorphisms and clinical response to Cmab did not reach a statistical significance. [Table: see text] No significant financial relationships to disclose.

Abstract
101 Background: S-1 plus cisplatin has been regarded as standard first-line chemotherapy for patients with AGC in Japan, and S- 1 plus docetaxel showed promising results for AGC in clinical trials. To investigate the usefulness of S-1 plus cisplatin alternating with S-1 plus docetaxel as first-line treatment in patients with AGC, we conducted a phase I/II study to determine the maximum tolerated dose (MTD), the recommended dose (RD), preliminary efficacy and toxicity. Methods: Eligibility criteria included pathologically confirmed AGC; no prior chemotherapy; Age 20 to 74, ECOG performance status (PS) of 0 to 2; adequate organ function; and written informed consent. Cisplatin was administered on day1 and the dose was escalated by 10 mg/m2 from starting dose of 40 mg/m2 in phase I part. S-1 was given orally at 80 mg/m2 on day1-14. Docetaxel was administered at 40 mg/m2 on day 22 in combination with S-1 80 mg/m2 on days 22-35. The treatment was repeated every 6 weeks. The RD was studied in every 3-6 patients cohort and determined according to the pre-defined DLTs. Primary endpoint of phase II was the response rate (RR). Results: Between Aug 2006 and Jul 2010, 33 pts were enrolled. Nine patients entered the phase I part and 24 enrolled in phase II part. In the phase I part, the MTD of cisplatin was presumed to be 50 mg/m2, because 50% of patients (3/6) developed DLTs. Therefore, the RD of cisplatin was estimated as 40 mg/m2, and the 27 patients received the treatment at RD level. Patients characteristics were as follows: median age=65 years (range 48-74), Male: female=21:6, PS 0:1:2=11:16:0, diffuse: intestinal=19:8, initially unresectable: recurrent=24:3. The RR was 59.2% (95% CI, 40.7-77.7). Median follow-up period was 14.6 months, median PFS was 7.9 months, and median survival time was 17.2 months, although survival data remain to be confirmed. Major grade 3/4 toxicities were neutropenia (63%), leucopenia (41%), and anemia (33%). These toxicities were tolerable and manageable. No treatment-related death was observed. The updated analysis will be presented at the meeting. Conclusions: This alternating treatment seems to be effective and well tolerated in the first-line treatments in patients with AGC. No significant financial relationships to disclose.

Abstract
Spina bifida is one of the most common open neural tube defects. There are two common types of spina bifida cystica, myelomeningocele and meningocele. Special attention to the thickness of the cystic sac (presence of intact skin and subcutaneous tissue) on magnetic resonance imaging is advantageous for determination of whether the child will profit from cesarean section in order to prevent neurological change (infection and drying of nerve tissue) and for management of spina bifida (most meningocele) during the perinatal period. Furthermore, skin detection may help to predict the prognosis of spina bifida after birth. Meningocele, with intact skin over the cyst, has a better clinical course than myelomeningocele. Some myelomeningoceles with neural tube defects in a lower position, also frequently having an intact skin over the cyst, have almost the same clinical course as a meningocele. From this, we hypothesize that a baby with spina bifida who has intact skin over the cyst might have a good prognosis neurologically. In this report, we concentrate attention on the skin over cysts in 3 cases (1 meningocele and 2 myelomeningoceles).

Abstract
Bartter syndrome is characterized by renal potassium and chloride loss, hypokalaemia, hypochloraemic metabolic alkalosis and increased plasma renin activity along with elevated angiotensin II and hyperaldosteronism. For diagnosis we conducted biochemical examinations of both amniotic fluid and the mother's urine. Except for potassium, amniotic fluid electrolytes in a mother with a fetus with Bartter syndrome were high. Urinary chloride, sodium and calcium were very low. Thus, the latter parameters may allow prediction of fetal Bartter syndrome during the prenatal period.

Abstract
PROBLEM It is well known that the prevalence of several autoantibodies is higher in patients with recurrent miscarriages than in normal women. However, links between individual autoantibodies are unclear. The present study focuses on the possible association between beta 2-glycoprotein I (beta 2-GPI)-dependent anticardiolipin antibody (aCL), lupus anticoagulant (LA), and antinuclear antibody (ANA) in patients with recurrent miscarriages. METHOD OF STUDY Three hundred and one patients, with a history of two or more unexplained miscarriages, were studied. The titers of beta 2-GPI-dependent aCL and LA were then compared between single-antibody-positive and three-antibody-positive groups. RESULTS The prevalences of beta 2-GPI-dependent aCL, LA, and ANA were 3.3, 10.0, and 25.2%, respectively. Four of the 301 patients had all three antibodies. The LA titers in patients with positive values for three antibodies was significantly higher than in cases with only LA. CONCLUSION beta 2-GPI-dependent aCL, LA, and ANA define three distinct, but partly related populations in patients with recurrent miscarriage. We should test at least two kinds of autoantibodies in recurrent aborters, because it has been found that, e.g., beta 2-GPI-dependent aCL and LA are predictors for miscarriages.

Abstract
Recently, a novel viral agent, hepatitis G virus, was identified by independent researchers from the serum of patients with liver disease, and termed GBV-C or HGV. At present, GBV-C and HGV are considered to be separate isolates of the same virus; however, the role of this virus in acute and chronic liver disease remains uncertain. Although vertical transmission is known to be one of the routes of transmission, the prevalence of GBV-C/HGV viremia in pregnant Japanese women is unknown. Thus, we determined this prevalence using the reverse transcription polymerase chain reaction (RT-PCR).

Abstract
We encountered a case of a pregnant woman with adrenal causes of Cushing's syndrome who exhibited congestive heart failure as an initial symptom. Since the patient was also a diabetic, we treated her with high levels of diuretics and insulin. Echocardiography revealed a remarkable thickening of the left ventricle without asymmetric hypertrophy. The diagnosis of Cushing's syndrome caused by adrenal adenoma was confirmed by the endocrinological data and magnetic resonance imaging. The right adrenal adenoma was removed in the 28th week of pregnancy. After the operation, her congestive heart failure and hyperglycemia dramatically improved. Five weeks after the operation, she delivered a normal infant by caesarean section without complications. Only 4 months after delivery, the thickening of her left ventricle was normalized. We consider that the progression of her left ventricular hypertrophy induced by the changes in hemodynamic load during pregnancy may have been augmented by the excess of plasma cortisol. Operative therapy may be recommended for pregnant Cushing's syndrome patients with severe hypercortisolism complicating congestive heart failure.

Abstract
OBJECTIVE To examine the predictive value of midluteal serum P as a marker of a luteal phase defect (LPD) in future pregnancies of recurrent aborters. DESIGN Prospective analysis. SETTING Nagoya City University Hospital. PATIENT(S) One hundred ninety-seven women with a history of two consecutive first trimester abortions, none of whom had any other medical problems or an identifiable cause of recurrent miscarriages, such as uterine anomalies or evidence of antiphospholipid antibodies. None of the study subjects received any medication for miscarriage or infertility. MAIN OUTCOME MEASURE(S) A midluteal phase single serum P level < 10 ng/mL was used as the criterion for a potential LPD: those whose subsequent pregnancy was successful and those in which failure was the end result. RESULT(S) Of the 197 patients, 46 (23.4%) demonstrated LPD without other endocrine abnormalities and 38 (19.3%) recurrent aborters suffered another abortion, with figures for LPD-negative and LPD-positive patients of 20.5% (31/151) and 15.2% (7/46), respectively. There was no statistically significant difference between the two groups. CONCLUSION(S) Progesterone, E2, and the P/E2 ratio may not predict future pregnancy loss in recurrent aborters.

Abstract
We determined clinically whether a killed streptococcal preparation (KSP), a biological response modifier, is as effective as paternal lymphocyte immunotherapy for unexplained recurrent pregnancy abortion (RSA) therapy. The success rate of adverse pregnancy in the study group of 23 RSA cases, who were administered low doses of KSP before and during early pregnancy, was statistically compared with that in a control group of 205 women who received paternal lymphocyte immunotherapy. The association of natural killer (NK) cell activity in the peripheral blood with pregnancy outcome was also assessed. The success rate in the study group was 73.9% (17/23), compared to 75.1% (154/ 205) observed for the controls (not significant). Most of the successful cases exhibited low levels of NK cell activity in the peripheral blood. Immunotherapy with low doses of KSP is as effective as that with paternal lymphocytes, providing a simple and safe alternative therapy for unexplained RSA. Suppression of NK cell activity by some immunoregulatory mechanism was also found to have potential benefit in terms of a successful pregnancy outcome.

Abstract
Both choledochal cyst and congenital biliary atresia (type I cyst) may share the same ultrasonographic pattern. We report 2 cases which were shown to have cystic structures on the upper abdomen by antenatal ultrasonography. The size of the choledochal cyst found at 24 weeks' gestation increased steadily as gestational age advanced. But the size of the cyst in congenital biliary atresia found at 29 weeks' gestation remained unchanged throughout the remaining pregnancy. Cyst enlargement, therefore, may suggest the possibility of a choledochal cyst.

Abstract
PROBLEM The purpose of this study was to determine whether the serum macrophage-colony stimulating factor (M-CSF) level is associated with early pregnancy loss in unexplained recurrent spontaneous abortion (RSA) patients. METHOD We therefore compared preconceptional serum M-CSF levels between unexplained RSA patients and controls. The former comprised 44 bed-rest therapy patients and 43 intradermal immunization (IDI) patients receiving paternal lymphocyte therapy, who had experienced two and three or more consecutive first-trimester pregnancy losses, respectively. The controls were 46 healthy non-pregnant women. We also prospectively studied the association between M-CSF levels during pregnancy and adverse pregnancy outcomes. Sera from a total of 31 pregnant women, including 16 of the bed-rest therapy group and 15 of the IDI therapy group, were collected at the 4th, 6th, and 8th gestational weeks and were measured for M-CSF levels, using the enzyme-linked immunoadsorbent assay (ELISA) method established by Hanamura et al. RESULTS Serum M-CSF levels were significantly lower in the non-pregnant RSA patients (460.0 +/- 185.6 U/ml; mean +/- SD) than in the control group (726.5 +/- 134.0 U/ml) and also were lower at the 8th, but not the 4th or 6th gestational week in those patients of both the bed-rest and IDI therapy groups whose outcome was pregnancy failure. CONCLUSION Thus a low level of serum M-CSF was found to be associated with unexplained recurrent pregnancy loss in both the preconceptional and conceptional phases. These results raise the possibility that M-CSF may play an important role in the maintenance of pregnancy and that it can be used as a parameter for determining individuals at risk.

Abstract
Cartilaginous fishes continuously replace their teeth throughout their life (polyphyodonty) and often show a sexually dimorphic dentition that was previously thought to be an invariant sex character. Radial vector analysis of tooth shape in the polyphyodontic stingray Dasyatis sabina across a consecutive 24 month period shows a stable molariform morphology for females but a periodic shift in male dentition from a female-like molariform to a recurved cuspidate form during the reproductive season. The grip tenacity of the male dentition is greater for the cuspidate form that occurs during the mating season than for the molariform dentition that occurs during the non-mating season. Dental sexual dimorphism and its sex-dependent temporal plasticity probably evolved via polyphyodontic preadaptation under selective pressures on both sexes for increased feeding efficiency and sexual selection in males to maximize mating success. These phenomena are important considerations for the identification and classification of cartilaginous fishes and possibly other polyphyodontic vertebrates in the fossil record.

Abstract
Allergic granulomatosis and angiitis was first reported as a disease entity separate from polyarteritis nodosa in 1951 by Churg and Strauss. It is characterized by bronchial asthma, eosinophilia, and vasculitis and is especially rare in women of reproductive age, though, when present, may be associated with fetal mortality in pregnancy. We report a successful pregnancy in a patient who previously experienced intrauterine fetal death at 30 weeks of gestation.

Abstract
A 29-year-old woman experienced unexplained intrauterine fetal death (IUFD) three times, at 16, 27 and 27 gestational weeks. She was found to be protein C-deficient and the existence of infarction in the placenta was suspected at 20 weeks' gestation during her fourth pregnancy. Both heparin and antithrombin III were administered until delivery of a small-for-dates but live baby. Massive infarction in the placenta was evident at term. Anticoagulation with heparin is a useful treatment approach for cases of recurrent IUFD with protein C deficiency.

Abstract
There is no immunological test for the prospective identification of alloimmune causes of miscarriage. We investigated whether activity of natural killer cells was predictive of subsequent abortion in women who had had unexplained recurrent abortions and had received no treatment. 24 women with high preconceptional NK activity, defined as mean plus 1 SD of NK activity of 47 controls, had a significantly higher abortion rate in the next pregnancy than 44 women with normal levels of NK activity (71 vs 20%; relative risk 3.5; 95% CI 1.8-6.5). The preconceptional evaluation of NK activity in women with recurrent miscarriages may thus be predictive of the risk of pregnancy loss at the next conception.

Abstract
Two new Capnocytophaga species, for which we propose the names Capnocytophaga haemolytica and Capnocytophaga granulosa, were isolated from supragingival dental plaque of adults. The phenotypic characteristics of these organisms were the same as those of the genus Capnocytophaga: gram-negative rods; CO2 requirement; gliding motility; catalase negative; oxidase negative; acids produced from D-glucose, D-maltose, D-mannose, and D-sucrose; and acetate and succinate are the major end products of glucose fermentation. In addition, the cellular fatty acid contents and menaquinones of both species were similar to the cellular fatty acid contents and menaquinones of other Capnocytophaga species. Nevertheless, the levels of DNA-DNA relatedness of the two new species to each other and to other Capnocytophaga species were less than 20%. Two notable characteristics of C. haemolytica are the presence of hemolytic activity and the lack of aminopeptidase activity. C. granulosa has granular inclusions in its cells and grows aerobically. The type strains of C. haemolytica and C. granulosa are A0404 (= JCM 8565) and B0611 (= JCM 8566), respectively.

Abstract
OBJECTIVE The purpose of this study was to evaluate the beneficial effect of immunotherapy for the treatment of recurrent abortion. STUDY DESIGN We immunized 106 primary recurrent aborters, twice at around 5 and 7 weeks of gestation, with intradermal injection of approximately 100 to 200 million x-irradiated (50 Gy) paternal mononuclear cells. We injected another 38 primary recurrent aborters in the same manner with only 1 million such paternal cells, to examine the relationship between the paternal cell dose used for immunization and pregnancy outcome. RESULTS The pregnancy success rate (83.0%) in patients immunized with a large number of cells was significantly higher than that (55.3%) in those immunized with a small number of cells (p < 0.001). Furthermore, the frequency of twins in the former group was high (5.7%, five of 88). CONCLUSION This positive relationship between the paternal cell dose used for immunization in early pregnancy and the pregnancy outcome reflects the efficacy of this mode of immunotherapy for recurrent aborters.

Abstract
Immunotherapy (immunization twice at 5 and 7 weeks of gestation with X-irradiated 200ml total blood or 1-200 x 10(6) mononuclear cells from the husband) was performed on 200 women without autoimmune abnormalities but experiencing habitual abortions of unknown causes between August, 1982 and September, 1990. One hundred fifty-seven babies were eventually born alive. The oldest offspring was 7 yrs 4 mos in August, 1991. We investigated the safety of the immunotherapy in terms of its effects on the women, conditions during pregnancy/labor and conducted long-term follow-up on offspring. Among 190 women whose pregnancy terminated by September, 1990, 152 cases gave birth, including 5 sets of twins. The successful rate was 80.0%. There were no complications among the 200 cases, only 2 small-for-dates babies (1.3%) among 157 babies born alive, and 1 baby born dead in the 3rd trimester, but that was not directly related with immunotherapy. Tsumori-Inage Infant Mental Development Test found no abnormalities (3 yrs and over). At 3 yrs, and only 1 child scored under the mean--2 standard deviation in height and weight. Thus, the safety of the immunotherapy was confirmed by long-term follow-up of both mother and child in which no notable complications resulting from immunotherapy with the husband's X-irradiated cells could be found.

Abstract
The autopsy of a stillborn infant showed an extensive intravascular proliferation of atypical cells throughout the body. There was no infiltration by these cells of the parenchyma of the bone marrow, lymph nodes, or thymus. By histochemistry, these cells were negative for naphthol-ASD-chloroacetate esterase, a marker of granulocytes. By immunohistochemistry, they were reactive with MT-1 and anti-Leu-22, but unreactive with MB-1, L26, anti-Leu-M1, Tü-9, and antihemoglobin antibodies. A few cells reacted with antileukocyte common antigen and UCHL-1. Based on these findings, the lesion was diagnosed as angiotropic lymphoma (intravascular lymphomatosis) of the T-cell type, which occurred congenitally. Most angiotropic lymphomas in the literature are of the B-cell type, and no leukemia virus type I antibody was negative in the mother.
