Atypical adenomatous hyperplasia (AAH) and adenocarcinoma in situ (AIS) are generally treated as different lesions, depending on the differences in lesion size and histological findings. However, these differences are not absolute; thus, AAH and AIS are often difficult to distinguish. Moreover, whether AAH and AIS can be regarded as different lesions remains unknown because cytological specimens, especially those of AAH, are rare. In this study, we examined these uncommon cytological specimens and compared the cytological findings between AAH and AIS. We observed many common cytological features with no obvious differences between AAH and AIS. These findings suggest that these two distinct lesions can be grouped into a single category. Therefore, we propose creating a new cytological category.

PURPOSE: Few studies have compared fractional exhaled nitric oxide (FeNO) measurement by NIOX VERO® (NOV) and other devices in children. Moreover, there is no agreement between differences in FeNO values obtained using different devices in adults. Here, we compared FeNO values obtained using NOV and NObreath® (NOB) systems to derive a correction equation for children. METHODS: Eighty-eight participants (age 7–15 years) who were diagnosed with atopic bronchial asthma and visited Sagamihara National Hospital as outpatients between January and April of 2017 were included. We measured FeNO values obtained using NOB and NOV, and analyzed them using Wilcoxon tests and Altman-Bland plots. RESULTS: The median age of the participants was 11.5 years, and the scored Asthma Control Test (ACT) or Childhood ACT (C-ACT) was 25 (interquartile range, 24–25) or 26 (24–27). NOB and NOV values were significantly different (31 [14–52] versus 36 [20–59] ppb; P = 0.020) and strongly correlated (r = 0.92). An equation to convert NOB values into NOV values was derived using linear regression as follows: log NOV = 0.7329 × log NOB + 0.4704; NOB for 20, 40, 58, 80 and 100 ppb corresponded to NOV for 27, 44, 59, 73 and 86 ppb. Thus, NOB < 58 ppb suggested NOB < NOV, whereas NOB > 58 ppb suggested NOB > NOV. CONCLUSIONS: NOB and NOV values were strongly correlated. Participants whose FeNO values were relatively low represented NOB < NOV, whereas those whose FeNO values were relatively high represented NOB > NOV.

BACKGROUND/AIMS: The influences of Helicobacter pylori eradication therapy on the disease course of inflammatory bowel disease (IBD) are still unclear. We therefore conducted a multicenter, retrospective cohort study to evaluate the safety of H. pylori eradication therapy for IBD patients. METHODS: IBD patients with H. pylori eradication from 2005 to 2015 (eradication group) and control patients (non-eradication group; 2 paired IBD patients without H. pylori eradication matched with each eradicated patient) were included. IBD exacerbation (increased/additional IBD drug or IBD-associated hospitalization/surgery) and disease improvement based on the physicians’ global assessment were investigated at baseline, and at 2 and 6 months after eradication or observation. RESULTS: A total of 429 IBD (378 ulcerative colitis, 51 Crohn’s disease) patients, comprising 144 patients in the eradication group and 285 patients in the non-eradication group, were enrolled at 25 institutions. IBD exacerbation was comparable between groups (eradication group: 8.3% at 2 months [odds ratio, 1.76; 95% confidence interval, 0.78–3.92; P=0.170], 11.8% at 6 months [odds ratio, 1.60; 95% confidence interval, 0.81–3.11; P=0.172]). Based on the physicians’ global assessment at 2 months, none of the patients in the eradication group improved, whereas 3.2% of the patients in the non-eradication group improved (P=0.019). Multivariate analysis revealed that active disease at baseline, but not H. pylori eradication, was an independent factor for IBD exacerbation during 2 months’ observation period. The overall eradication rate was 84.0%–comparable to previous reports in non-IBD patients. CONCLUSIONS: H. pylori eradication therapy does not alter the short-term disease activity of IBD.

The purpose of this study was to explore the burden of introducing LCP-J in two wards（medical oncology and respiratory medicine）in Tohoku University Hospital. We administered audit evaluations about dying cancer patients and interviewed 2 doctors and 8 nurses regarding LCP-J intervention. LCP-J was used for 22 patients（38％）, and no significant difference in infusion, potent opioid analgesic and sedative medication within last 48 hours were seen between users and nonusers. Responses were categorized into［confirm directions about dying care among health care professionals］, and［training in dying care in a structured way］as usefulness facets of the LCP-J, and［difficulty in assessment of dying］,［burden of health care professionals］, and［difficulty using LCP-J without knowledge and training in dying care］as burdens of the LCP-J. We explored the burden of LCP-J in general wards, and found that use of the LCP-J could need education in dying care and backup of the palliative care team.

Objective: The overproduction of reactive oxygen species leads to oxidative stress, which is related to lifestyle-related disease and cancer. Although antioxidants are considered as one of the countermeasures to oxidative stress, it is necessary to develop the assessment methodology for the antioxidant capacity which is closer to the inner body conditions. In this study, we examined antioxidant actions of plant extracts by using newly-developed neutrophil activity measurement system.
Method: Lemon verbena, Green tea, Camellia japonica and Antiallerge^® were used as plant extracts, and were diluted to medium in wide-range concentrations. Each solution was added on modified Mebiol Gel^® (hydrogel), and the mixture of blood and luminol were set onto the hydrogel in each tube. The amount of reactive oxygen species were measured by luminol-dependent chemiluminescence, whereas the cell count in the hydrogel was quantified as migratory activity of neutrophils.
Result: Lemon verbena and Green tea significantly inhibited reactive oxygen species in a concentration-dependent manner, whereas Camellia japonica and Antiallerge^® did not. The migratory activity of neutrophils was not affected by those plant extracts. Also, damaged cells were not detected.
Conclusion: It was suggested that Lemon verbena and Green tea scavenged reactive oxygen species without causing cell death of neutrophils. This new method for measuring neutrophil activities can be applied not only for assessing the status of inflammation and oxidative stress but also as the screening system for predicting the effectiveness of antioxidant and anti-inflammatory substances.

Prepulse inhibition (PPI) is considered to be one of the most promising neurophysiological indexes for translational research in psychiatry. Impairment of PPI has been reported in several psychiatric diseases, particularly schizophrenia, where PPI is considered a candidate intermediate phenotype (endophenotype) of the disease. Recent findings from a variety of research areas have provided important evidence regarding PPI impairment. Human brain imaging studies have demonstrated the involvement of the striatum, hippocampus, thalamus and frontal and parietal cortical regions in PPI. In addition, several genetic polymorphisms, including variations in the genes coding for Catechol O-methyltransferase, Neuregulin 1, nuclear factor kappa-B subunit 3 and serotonin-2A receptor were related to PPI; and these findings support PPI as a polygenetic trait that involves several neurotransmitter pathways. Early psychosis studies suggest that PPI disruption is present before the onset of psychosis. Also, discrepancy of PPI impairment between children and adults can be found in other psychiatric diseases, such as autistic spectrum disorders and posttraumatic stress disorder, and comprehensive investigation of startle response might contribute to understand the impairment of the neural circuitry in psychiatric diseases. Finally, recent studies with both Asian and Caucasian subjects indicate that patients with schizophrenia exhibit impaired PPI, and impaired sensorimotor gating might be a global common psychophysiological feature of schizophrenia. In conclusion, studies of PPI have successfully contributed to a better understanding of the fundamental neural mechanisms underlying sensorimotor gating and will certainly be most valuable in devising future approaches that aim to investigate the complex pathogenesis of psychiatric diseases.
