Abstract
BACKGROUND Corticosteroids, especially prednisolone or prednisone, are the most commonly used drugs for the treatment of bullous pemphigoid (BP). However, the appropriate initial effective prednisolone dose has not been established. Recently, a highly sensitive and specific ELISA for detection of autoantibodies to the non-collagenous extracellular domain (NC16A) of the 180 kDa transmembrane hemidesmosome component [bullous pemphigoid (BP)180] was developed, and the titre of anti-BP180 antibody was found to be closely related to disease activity. AIM To investigate the relationship between anti-BP180 antibody titre and effective prednisolone dose alone or in conjunction with other immunosuppressants. METHODS Anti-BP180 antibody titres were measured by ELISA for the NC16A domain of BP180 in the sera of patients with BP (n = 42) at the start of treatment. The effective prednisolone dose was calculated from the patients' records. RESULTS Higher anti-BP180 antibody titres correlated with a higher effective prednisolone dose. In particular, patients with antibody titres > 200 required a significantly higher effective prednisolone dose than did those with antibody titres ≤ 200. CONCLUSIONS A higher effective prednisolone dose may be necessary for patients who have both a high titre of anti-BP180 antibody and severe clinical disease.

Abstract
Background: Several recent studies demonstrated that microRNAs (miRNAs) are stably detectable in plasma/serum. We hypothesised that plasma miRNAs concentrations contributed to potential biomarkers in patients with oesophageal squamous cell carcinoma (ESCC). Methods: We selected three oncogenic miRNAs (miR-21, miR-184, miR-221) and one tumour suppressive miRNA (miR-375), which are frequently reported in squamous cell carcinoma, as candidate targets for this plasma miRNA assay. This study was divided into three steps: (1) Determination of appropriate plasma miRNAs in preliminary tests. (2) Evaluation of whether the plasma miRNA assays could monitor tumour dynamics. (3) Validation study on the clinical application of plasma miRNA assays in 50 ESCC patients and 20 healthy volunteers. Results: (1) In preliminary tests, the plasma level of miR-21 was significantly higher (P=0.0218) and that of miR-375 (P=0.0052) was significantly lower in ESCC patients than controls. (2) The high plasma miR-21 levels reflected tumour levels in all cases (100%). The plasma level of miR-21 was significantly reduced in postoperative samples (P=0.0058). (3) On validation analysis, the plasma level of miR-21 tended to be higher in ESCC patients (P=0.0649), while that of miR-375 was significantly lower (P<0.0001) and the miR-21/miR-375 ratio was significantly higher (P<0.0001) in ESCC patients than in controls. The value of the area under the receiver-operating characteristic curve (AUC) was 0.816 for the miR-21/miR-375 ratio assay. Patients with a high plasma level of miR-21 tended to have greater vascular invasion (P=0.1554) and to show a high correlation with recurrence (P=0.0164). Conclusion: Detection of circulating miRNAs might provide new complementary tumour markers for ESCC.

Abstract
Anterior sacral meningocele is an extremely rare condition and there has been only one previous report of a prenatal diagnosis. We report the case of a 36-year-old primigravida who was referred following detection of a huge fetal pelvic cyst on routine ultrasound examination at 19 + 4 weeks' gestation. Neither fetal ultrasound nor magnetic resonance imaging (MRI) at 20 + 5 weeks' gestation could detect communication between the cyst and the spinal cord. Because extension of the pear-shaped cyst through the pelvic diaphragm down to the perineum was reminiscent of dilated vagina and uterine cervix, a tentative diagnosis of hydrometrocolpos secondary to imperforate hymen was considered. On follow-up MRI at 33 + 5 weeks' gestation, a narrow stalk connecting the pelvic cyst and the spinal canal through the anterior sacral foramen was clearly delineated, allowing us to reach the prenatal diagnosis of anterior sacral meningocele.

Abstract
There has been no prospective study on age-related changes of the extensor muscles of the cervical spine in healthy subjects. This study was conducted to elucidate any association between the changes in cross-sectional area of the extensor muscles of the cervical spine on MRIs and cervical disc degeneration or the development of clinical symptoms. Sixty-two subjects who underwent MR imaging by a 1.5-Tesla machine between 1993 and 1996 as asymptomatic volunteers in a previous study were recruited again 10 years later for this follow-up study. The mean interval between the studies was 11.0 ± 0.7 years. The cross-sectional areas of the multifidus, semispinalis cervicis, semispinalis capitis, and splenius capitis at C3-C4, C4-C5, and C5-C6 intervertebral levels were measured on T2-weighted axial images using Image J 1.42. The mean cross-sectional areas of the deep extensor muscles were 1,396.8 ± 337.6 mm(2) at the C3-C4 level, 1,514.7 ± 381.0 mm(2) at the C4-C5 level, and 1,542.8 ± 373.5 mm(2) at the C5-C6 level in the previous investigation. The cross-sectional areas were 1,498.7 ± 374.4 mm(2) at the C3-C4 level, 1,569.9 ± 390.9 mm(2) at the C4-C5 level, and 1,599.6 ± 364.3 mm(2) at the 10-year follow-up. An increase in the cross-sectional area of the muscles was more frequently observed in subjects in their tens to thirties in the initial study, while a decrease was more frequently observed in those in their forties and older in the initial study. Disc degeneration was not correlated with a change in extensor muscle volume. Development of shoulder stiffness during follow-up was significantly negatively correlated with a change in the cross-sectional area of the deep extensor muscles.

Abstract
We describe a case of congenital meconium peritonitis with progressive fetal ascites and polyhydramnios. Fetal ascites could be only partially reduced on paracentesis at 29 weeks' gestation, and it subsequently increased. Urinary trypsin inhibitor (UTI), a physiological anti-inflammatory substance, was administered into the fetal abdominal cavity at a second paracentesis performed at 35 weeks' gestation. There was a significant amount of fetal ascites remaining 1 day after the second paracentesis, but this completely resolved within 5 days. A healthy infant was delivered vaginally and no surgical intervention was required. The case suggests that UTI can reduce meconium-induced chemical peritonitis and thereby facilitate intrauterine remission of fetal ascites.

Abstract
The deposition of amyloid β protein (Aβ) is a consistent pathological hallmark of Alzheimer's disease (AD) brains. Therefore, inhibition of Aβ aggregation in the brain is an attractive therapeutic and preventive strategy in the development of disease-modifying drugs for AD. An in vitro study demonstrated that yokukansan (YKS), a traditional Japanese medicine, inhibited Aβ aggregation in a concentration-dependent manner. An in vivo study demonstrated that YKS and Uncaria hook (UH), a constituent of YKS, prevented the accumulation of cerebral Aβ. YKS also improved the memory disturbance and abnormal social interaction such as increased aggressive behavior and decreased social behavior in amyloid precursor protein transgenic mice. These results suggest that YKS is likely to be a potent and novel therapeutic agent to prevent and/or treat AD, and that this may be attributed to UH.

Abstract
OBJECTIVES To evaluate the diagnostic value of individual noninvasive presurgical modalities and to study their role in surgical management of nonlesional pediatric epilepsy patients. METHODS We retrospectively studied 14 children (3-18 years) with nonlesional intractable focal epilepsy. Clinical characteristics, surgical outcome, localizing features on 3 presurgical diagnostic tests (subtraction peri-ictal SPECT coregistered to MRI [SISCOM], statistical parametric mapping [SPM] analysis of [18F] FDG-PET, magnetoencephalography [MEG]), and intracranial EEG (iEEG) were reviewed. The localization of each individual test was determined for lobar location by visual inspection. Concordance of localization between each test and iEEG was scored as follows: 2=lobar concordance; 1=hemispheric concordance; 0=discordance or nonlocalization. Total concordance score in each patient was measured by the summation of concordance scores for all 3 tests. RESULTS Seven (50%) of 14 patients were seizure-free for at least 12 months after surgery. One (7%) had only rare seizures and 6 (43%) had persistent seizures. MEG (79%, 11/14) and SISCOM (79%, 11/14) showed greater lobar concordance with iEEG than SPM-PET (13%, 3/14) (p<0.05). SPM-PET provided hemispheric lateralization (71%, 10/14) more often than lobar localization. Total concordance score tended to be greater for seizure-free patients (4.7) than for non-seizure-free patients (3.9). CONCLUSIONS Our data suggest that MEG and SISCOM are better tools for lobar localization than SPM analysis of FDG-PET in children with nonlesional epilepsy. A multimodality approach may improve surgical outcome as well as selection of surgical candidates in patients without MRI abnormalities.

Abstract
Embryo-maternal recognition is known to be mediated by the trophoblast and/or its secretory product during the preimplantation period. However, it was recently proposed that embryo-maternal recognition (along with the maternal immune system) could be activated by zona pellucida-degradation products including oligosaccharide chains from very early stage embryos (Fujiwara et al. 2009 J. Reprod. Immunol. 81, 1–8). If this is true, we predict that mammalian mothers recognise the presence of an embryo immediately after fertilization in vivo. The purpose of the present study was to compare the expressions of immune tolerance genes in bovine endometrial-luminal lymphoid (ELL) cells collected from animals after AI or embryo transfer (ET). ELL cells were collected from recipient cows inseminated with frozen–thawed semen on Day 0 (=oestrus, n = 8) and from cows that received a transferred embryo on Day 7 (n = 8) of the oestrous cycle. On Days 9 and 11, ELL cells ipsilateral to the corpus luteum were flushed non-surgically from four cows of each group using Ringer's solution (500 mL). To eliminate large cell clusters of endometrium and the embryo (blastocyst), the flushing medium was passed through an embryo collection filter (EmCon filter, 75 μm stainless steel screen). A single viable blastocyst was collected from each recipient cow. The recovered flushing medium containing ELL cells was centrifuged. The ELL cells were suspended in PBS and separated by Lympholyte-H (Cedarlane, Ontario, Canada) gradient centrifugation. Using RT-real-time PCR, transcripts for four immune tolerance genes in ELL cells from AI or ET examined were transforming growth factor-β (TGF-β), macrophage-colony stimulating factor (M-CSF), interleukin-10 (IL-10), and forkhead box P3 (Foxp3). Data were normalized to that of an endogenous control (glyceraldehyde-3-phosphate dehydrogenase) and analysed using ANOVA followed by Scheffe′s test. Transcripts for TGF-β, M-CSF, IL-10, and Foxp3 were detected in all RT-samples derived from ELL cells on Days 9 and 11 of the oestrous cycle. Transcript levels of TGF-β, M-CSF and IL-10 in the AI group were the same as those of the ET group (P > 0.05), although the transcript level of Foxp3, a master regulator of the function of regulatory T-cells, in the AI group was significantly higher than that of the ET group on Days 9 and 11 (P < 0.05). Furthermore, the transcript level of Foxp3 in the ET group on Day 11 was significantly higher than that of the ET group on Day 9 (P < 0.05). These results indicate that the embryo-maternal recognition in AI occurs earlier than in ET, and suggest that cows recognise an embryo earlier than those generally believed.

Abstract
An association between progression of cervical disc degeneration and that of lumbar disc degeneration has been considered to exist. To date, however, this association has not yet been adequately studied. Age-related changes in the cervical intervertebral discs were evaluated by magnetic resonance imaging (MRI) in patients with lumbar disc herniation, and compared with the MRI findings of healthy volunteers without lower back pain. The purpose of this study was to clarify whether the prevalence of asymptomatic cervical disc degeneration is higher in patients with lumbar disc herniation than in healthy volunteers. The study was conducted on 51 patients who were diagnosed as having lumbar disc herniation and underwent cervical spine MRI. The patients consisted of 34 males and 17 females ranging in age from 21-83 years (mean 46.9 ± 14.5 years) at the time of the study. The control group was composed of 113 healthy volunteers (70 males and 43 females) aged 24-77 years (mean 48.9 ± 14.7 years), without neck pain or low back pain. The percentage of subjects with degenerative changes in the cervical discs was 98.0% in the lumbar disc herniation group and 88.5% in the control group (p = 0.034). The presence of lumbar disc herniation was associated significantly with decrease in signal intensity of intervertebral disc and posterior disc protrusion in the cervical spine. None of the MRI findings was significantly associated with the gender, smoking, sports activities, or BMI. As compared to healthy volunteers, patients with lumbar disc herniation showed a higher prevalence of decrease in signal intensity of intervertebral disc and posterior disc protrusion on MRI of the cervical spine. The result of this study suggests that disc degeneration appears to be a systemic phenomenon.

Abstract
The need for not only bulk sensitive but also extremely high resolution photoelectron spectroscopy for studying detailed electronic structures of strongly correlated electron systems is growing rapidly. Moreover, easy access to such a capability in one's own laboratory is desirable. Demonstrated here is the performance of a microwave excited rare gas (Xe, Kr, and Ar) lamp combined with ionic crystal filters (sapphire, CaF(2), and LiF), which can supply three strong lines near the photon energy of hnyu hν=8.4, 10.0, and 11.6 eV, with the hν resolution of better than 600 μeV for photoelectron spectroscopy. Its performance is demonstrated on some materials by means of both angle-integrated and angle-resolved measurements.

Abstract
OBJECTIVES The purpose of this study was to longitudinally evaluate relationships between the incidence of stiff shoulder and sagittal alignments of the cervical spine, age-related changes on magnetic resonance imaging (MRI) and life styles of the subjects. METHODS The subjects were 69 men and 93 women. The mean follow-up period was 11.3 +/- 0.7 years. Sagittal alignments of the cervical spine were classified into the following 4 types: lordosis, straight, kyphosis and sigmoid. MRI findings were evaluated for the progression of 1) decrease in signal intensity of disc, 2) posterior disc protrusion, and 3) disc space narrowing. RESULTS Stiff shoulder was found in 29.6% of the subjects over the 10 years. In the group of subjects 30-49 years old, the incidence of stiff shoulder was 40.4%, and it was higher than those in other age groups. Stiff shoulder was significantly more frequent in women (45.2%) than in men. Its incidence was significantly lower in those who regularly participated in sports or exercise. There were no significant relationship between the incidence of stiff shoulder and the progressions in any of MRI findings during the follow-up period. CONCLUSIONS Stiff shoulder was more frequent in middle-aged, female and non-exercising subjects. There was no correlation between the incidence of stiff shoulder and sagittal alignments of the cervical spine, or progression of age-related changes of the cervical disc on MRI.

Abstract
Background: We aimed to develop a new biomarker to predict cyclin D1 (CCND1) status using plasma DNA in oesophageal squamous cell carcinoma (ESCC) patients. Methods: We evaluated the ratio of the CCND1 (11q13) dosage to the dopamine receptor D2 (DRD2; 11q22-23) dosage (C/D ratio) as CCND1 copy number. This study was divided into three steps: (1) Determination of a cutoff value for the C/D ratio in test scale; (2) Comparison of the C/D ratio in between plasma samples and cancer tissues in ESCC patients showing high plasma C/D ratio; (3) Validation study of the clinical application of the plasma C/D ratio as a diagnostic and prognostic marker, by comparing with clinicopathologic factors in 96 ESCC patients. Results: The plasma C/D ratio was significantly higher in the ESCC group than the controls (P=0.0134). A high plasma C/D ratio reflected the tumour C/D ratio, and significantly correlated with a poorer prognosis (P=0.0186). Moreover, the high C/D ratio was found to be an independent prognostic factor on multivariate analysis (P=0.0266; hazard ratio 5.988). Conclusion: Prediction of CCND1 amplification using plasma DNA is thought to be a promising prognostic biomarker in ESCC patients.

Abstract
Reversible posterior leukoencephalopathy syndrome (RPLS) is a rare clinical entity, the common clinical symptoms of which are headache, disturbance of consciousness, altered mental status, seizures, and visual disturbance. Recently, some cases have been reported in association with the increased use of cytotoxic and immunosuppressive agents in cancer patients, and relevant reports have increased with advances in radiological examinations. We describe here the case of a 50-year-old man with advanced bladder cancer who suddenly experienced diminished spontaneity and speech, and finally became semicomatose. Two months previously, he had received gemcitabine and cisplatin chemotherapy. Computed tomography and magnetic resonance imaging revealed symmetrical edema of the posterior occipital lobe and thalamus. Based on these findings, we made a diagnosis of RPLS and treated him with supportive measures. His mental status gradually improved in 2 weeks, although slight neurological symptoms persisted. When the level of consciousness of a cancer patient worsens rapidly, this syndrome should be included in the differential diagnosis and recognized at an early stage. Early supportive management and discontinuation of the causative medication may reverse the clinical and radiological manifestations of the syndrome.
