Predictors and preventers of postoperative bedridden status in the elderly ages over 75 after emergency general surgery: a retrospective cohort study. Acute Med Surg 2023; 10:e844. [PMID: 37207116 PMCID: PMC10190121 DOI: 10.1002/ams2.844] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 04/13/2023] [Indexed: 05/21/2023] Open
Abstract
Aim We investigated the proportion of bedridden patients after emergency surgery among the elderly ages over 75; defined as the latter-stage elderly in Japan, the associated factors, and interventions used to prevent it. Methods Eighty-two latter-stage elderly patients who underwent emergency surgery for non-traumatic illness between January 2020 and June 2021 in our hospital were included in the study. Backgrounds and various perioperative factors were compared retrospectively between the groups including patients who became bedridden from Performance Status Scale 0 to 3 before admission (Bedridden group) and those who did not (Keep group). Results Three cases of death and seven patients who were bedridden before admission were excluded. The 72 remaining patients were divided into the Bedridden group (n = 10, 13.9%) and the Keep group (n = 62, 86.1%). There were significant differences in the prevalence of dementia, pre- and postoperative circulatory dynamics, renal dysfunction, coagulation abnormality, length of stay in the high care unit/intensive care unit, and number of hospital days, with a relative risk of 13 (1.74-96.71), a sensitivity of 1.00, and a specificity of 0.67 for a preoperative shock index of 0.7 or higher being associated with the Bedridden group. Among patients with a preoperative shock index of 0.7 or higher, there was a significant difference in SI at 24 h postoperatively between the two groups. Conclusion Preoperative shock index may be the most sensitive predictor. Early circulatory stabilization seems to be protective against patients becoming bedridden.

Post COVID-19 condition of the Omicron variant of SARS-CoV-2. J Infect Chemother 2022; 28:1546-1551. [PMID: 35963600 PMCID: PMC9365517 DOI: 10.1016/j.jiac.2022.08.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 07/18/2022] [Accepted: 08/04/2022] [Indexed: 12/12/2022]
Abstract
Objectives To investigate the prevalence of post coronavirus disease (COVID-19) condition of the Omicron variant in comparison to other strains. Study design A single-center cross-sectional study. Methods Patients who recovered from Omicron COVID-19 infection (Omicron group) were interviewed via telephone, and patients infected with other strains (control group) were surveyed via a self-reporting questionnaire. Data on patients’ characteristics, information regarding the acute-phase COVID-19, as well as presence and duration of COVID-19-related symptoms were obtained. Post COVID-19 condition in this study was defined as a symptom that lasted for at least 2 months, within 3 months of COVID-19 onset. We investigated and compared the prevalence of post COVID-19 condition in both groups after performing propensity score matching. Results We conducted interviews for 53 out of 128 patients with Omicron and obtained 502 responses in the control group. After matching cases with controls, 18 patients from both groups had improved covariate balance of the factors: older adult, female sex, obesity, and vaccination status. There were no significant differences in the prevalence of each post COVID-19 condition between the two groups. The number of patients with at least one post COVID-19 condition in the Omicron and control groups were 1 (5.6%) and 10 (55.6%) (p = 0.003), respectively. Conclusions The prevalence of post Omicron COVID-19 conditions was less than that of the other strains. Further research with a larger sample size is needed to investigate the precise epidemiology of post COVID-19 condition of Omicron, and its impact on health-related quality of life and social productivity.

Abstract
1049 Background: Asymptomatic metastatic breast cancer (mBC) is often detected using tumor marker or imaging tests in Japan. At the ASCO 2019, we reported on mBC detection, the distribution of symptomatic and asymptomatic disease by subtype (abstract e12568). We aimed to determine whether there are differences in post-recurrence survival (PRS), and treatment between asymptomatic and symptomatic MBCs, and identify factors associated with PRS. Methods: We performed a multicenter, retrospective analysis of patients with mBC treated in our hospitals from 2008 to 2018. Patients were divided into asymptomatic and symptomatic MBCs to compare their prognosis by breast cancer (BC) subtypes: luminal (hormone receptor positive/human epidermal growth factor 2 [HER2] negative), HER2 (any hormone receptor/HER2 positive), and triple-negative (TN) (hormone receptor negative/HER2 negative). Results: Of 204 patients with mBC (114 asymptomatic, 90 symptomatic), PRS was longer in asymptomatic mBC than in symptomatic mBC (median survival: 55 months vs. 29 months; p < 0.001) and tended to have longer overall survival (OS) (110 months vs 72 months, respectively; p = 0.09). In multivariate analysis, TN, recurrence-free survival (RFS), multiple metastasis sites, and symptomatic disease were independently predictive of PRS (Table). In luminal and HER2, PRS trended higher in the asymptomatic group than in the symptomatic group (luminal: 54 months vs. 41 months; p = 0.08, HER2: 71 months vs. 27 months; p = 0.09), but without significant difference in OS (luminal: 112 months vs. 124 months; p = 0.91, HER2: 113 months vs. 72 months; p = 0.40). In the luminal group, 13 patients (11%) were treated with cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. The median PRS was 80 months for luminal patients with three factors — longer than 4 years of RFS, a single metastasis site, and asymptomatic disease. The duration of endocrine therapy did not differ between groups; however, the patients with luminal BC in the asymptomatic group had longer chemotherapy than those in the symptomatic group. In TN, PRS was very short (asymptomatic, 28 months; symptomatic, 10.5 months; p = 0.01). Conclusions: We demonstrated that asymptomatic MBC and symptomatic MBC differed in terms of subtypes, prognosis, and duration of chemotherapy in the luminal group. Therefore, unique treatment strategy for asymptomatic or symptomatic MBC should be developed. [Table: see text]

Denosumab-related osteonecrosis of the jaw after tooth extraction and the effects of a short drug holiday in cancer patients: a multicenter retrospective study. Osteoporos Int 2021; 32:2323-2333. [PMID: 33997909 DOI: 10.1007/s00198-021-05995-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 05/05/2021] [Indexed: 12/15/2022]
Abstract
UNLABELLED Pre-existing inflammation, corticosteroid therapy, periapical periodontitis, longer duration of denosumab therapy, and female sex were significantly associated with an increased risk of denosumab-related osteonecrosis of the jaw after tooth extraction in patients with cancer on oncologic doses of denosumab. A short drug holiday did not protect against this complication. INTRODUCTION This study retrospectively investigated the relationship between various risk factors, including brief discontinuation of denosumab, and development of denosumab-related osteonecrosis of the jaw (DRONJ) after tooth extraction in patients with cancer who were receiving oncologic doses of this agent. METHODS Data were collected on demographic characteristics, duration of denosumab therapy, whether or not denosumab was discontinued before tooth extraction (drug holiday), duration of discontinuation, presence of pre-existing inflammation, and whether or not additional surgical procedures were performed. Risk factors for DRONJ after tooth extraction were evaluated by univariate and multivariate analyses. RESULTS A total of 136 dental extractions were performed in 72 patients (31 men, 41 women) with cancer who were receiving oncologic doses of denosumab. Post-extraction DRONJ was diagnosed in 39 teeth (28.7%) in 25 patients. Tooth extraction was significantly associated with development of DRONJ only in patients with pre-existing inflammation (odds ratio [OR] 243.77), those on corticosteroid therapy (OR 73.50), those with periapical periodontitis (OR 14.13), those who had been taking oncologic doses of denosumab for a longer period (OR 4.69), and in women (OR 1.04). There was no significant difference in the occurrence of DRONJ between patients who had a drug holiday before tooth extraction and those who did not. CONCLUSIONS These findings suggest that inflamed teeth should be extracted immediately in patients with cancer who are receiving oncologic doses of denosumab. Drug holidays have no significant impact on the risk of DRONJ.

ER staining levels affect HER2 staining and heterogeneity. Breast Cancer 2021; 28:720-726. [PMID: 33423217 DOI: 10.1007/s12282-020-01208-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Accepted: 12/20/2020] [Indexed: 11/28/2022]
Abstract
PURPOSE This study explored the relationship of ER expression levels with HER2 staining properties and heterogeneity and discussed the differences in HER2 assessment caused by the 2018 ASCO/CAP guideline updates from that of the 2013 version. METHODS HER2-positive breast cancer was divided into three groups of the high hormone receptor expression (LH-high) group, low expression (LH-low) group, or negative (NLH) group to (1) compare differences in the percentage of the HER2 IHC test score of 2 + based on the 2013 ASCO/CAP guideline and in the intratumor heterogeneity of HER2 expression for breast cancer with an IHC score of 3 + among these groups, (2) compare the HER2/CEP17 ratio and the average HER2 copy number, and classified ISH groupings according to the 2018 ASCO/CAP guideline algorithm. RESULTS (1) Of 244 HER2-positive breast cancers, the cases with a HER2 IHC score of 2 + (n = 54, 22.1%) were significantly more common in the LH-high group (n = 45, P < 0.001). The frequency of heterogeneity was low (n = 25, 10.2%) for the HER2 score of 3 + (n = 190, 77.9%), and significantly higher in the LH-high group (n = 19, 76%, P = 0.002). (2) In a HER2 IHC score of 2 + , Group 2 which is deemed HER2 negative according to the revised 2018 ASCO/CAP guideline was observed in 17 (39.5%) out of 43 cases, of which 16 cases (94.1%) were in the LH-high group. CONCLUSIONS The LH-high group is a heterogeneous group largely consisting of heterogeneous cases with HER2 IHC scores of 2 + or 3 + . NLH, in contrast, is a homogenous group.

Abstract
Clinical evidence has indicated that, after neo-adjuvant chemotherapy(NAC), sentinel node(SN)identification rates(IR) were lower and false-negative rates(FNR)were higher for patients(pts)with local advanced breast cancer(BC)than for pts with early stage BC who did not receive NAC. Our previous clinical trial indicated that the real-time indocyanin green (RT-ICG)fluorescence imaging technique could improve the diagnostic sensitivity and detection accuracy of sentinel node biopsy(SNB). Nine pts with histologically confirmed Stage ⅡA to ⅢB, T1-T3, N0-2, M0 BC were selected to receive NAC, and the standard surgeries were performed after NAC completion. The SNs were detected by using conventional procedures with the blue dye(indigo carmine)plus 99mTc radioisotope techniques combined with concurrent RT-ICG. Clinically positive nodes were diagnosed by the radiologists using axillary ultrasound, MRI, and/or CT scans. All pts provided written informed consent before surgery. The surgical SNB was guided via RT-ICG fluorescence under standard light conditions by using the HEMS imaging system as previously published. All pts underwent SNB followed by completion node dissection(CND). The IR and FNR were calculated by comparing the results of the SNB and the histopathology of the resection specimens obtained via CND. The IR and FNR for each procedure of SNB were, respectively, 35.3% and 41.7% when indigo carmine blue was used, 82.4% and 0 when ICG fluorescence was used, and 58.8% and 5% when RI was used. In contrast, the total calculation of the triple tracer showed that IR reached 100% and FNR was 0. These data suggest that IR and FNR of SNB might be improved in pts with BC treated with NAC by using the novel triple tracer technique.

Abstract
Abstract
Introduction
Diabetes (DM) is the leading cause of induction of hemodialysis (HD), and both are major prognostic factors in patients with peripheral artery disease (PAD). However, the prognostic importance of baseline glycated hemoglobin (HbA1c) levels in PAD patients with and without HD is yet to be elucidated.
Purpose
We hypothesized that baseline HbA1c levels had different prognostic impacts after endovascular therapy (EVT) in between PAD patients with and those without regular HD.
Methods
This observational study included 643 consecutive patients who received EVT between 2013 and 2017. Each of 313 HD patients and 330 Non-HD patients was respectively divided into 2 groups by the comorbidity of diabetes, and DM patients were further divided into 3 subgroups depending on HbA1c level at the time of EVT; DM-Low (HbA1c: <6.0%), DM-Mid (6.1–7.0%), and DM-High (>7.1%) groups. The primary endpoint of this study was major amputation-free survival (AFS).
Results
HD group included significantly more patients presenting critical limb ischemia than Non-HD group (46.6% vs. 30.0%, p<0.001). During the observation period after EVT, there were 81 events (25.9%), including 55 death and 26 major amputations in HD group, and 45 events (13.6%), including 30 death and 15 major amputations in Non-HD group. Kaplan-Meier analysis revealed that DM patients had a significantly higher AFS rate in HD group (Log-rank: p=0.003, Figure A). In contrast, in Non-HD group, there was no statistical difference in AFS between DM and Non-DM patients (p=0.36). In Cox regression analysis in HD group, the higher HbA1c-DM group showed the higher hazard ratio (HR) for AFS (p=0.039, Figure B), and DM patients with HbA1c >6.0% had significantly higher HR than Non-DM patients. Whereas, in Non-HD group, HbA1c-DM class adversely associated with HR for AFS (p=0.003), even any classes did not reach statistical differences from Non-DM patients.
Figure 1
Conclusions
Comorbidity of diabetes at the time of EVT worsened long-term prognosis in PAD patients receiving regular HD, but not in those without HD. Additionally, baseline HbA1c levels oppositely affected prognosis in PAD patients with and without HD.

Abstract
A 68-year-old woman with liver dysfunction was diagnosed with nonalcoholic steatohepatitis (NASH) stage 1. Three years later, she showed massive ascites and jaundice. A trans-jugular liver biopsy confirmed advanced cirrhosis, suggesting that her liver fibrosis had progressed rapidly. At the same time, she was diagnosed with multiple myeloma (MM). In this case, the plasma levels of osteopontin (OPN), a proinflammatory cytokine that promotes liver fibrosis progression through the hedgehog pathway and is increased in patients with MM, were increased. This increased OPN expression was accompanied by the upregulation of the hedgehog pathway in this patient, suggesting that the MM-associated increase in OPN had promoted the progression of liver fibrosis through the hedgehog pathway. The progression of liver fibrosis should be monitored in patients with NASH if other diseases, such as MM, are present.

Abstract
A 77-year-old patient was admitted to our hospital for the further examination of melena. A computed tomography scan detected two submucosal tumors (SMTs) in the stomach and jejunum. Double-balloon endoscopy revealed the presence of a delle on the jejunal SMT, suggesting that the SMT was the origin of the gastrointestinal bleeding. Both tumors were surgically resected and subsequently diagnosed via histology as gastrointestinal stromal tumors (GISTs). Furthermore, the two GISTs had different mutations in the c-kit gene, suggesting that they were derived from different clonal origins. This report depicts an extremely rare case of multiple synchronous sporadic GISTs in the stomach and jejunum.

Abstract
Abstract
Background: We have previously reported the prognostic role of humoral antigen spreading response against prostate-related antigen (PRA) for metastatic recurrent breast cancer (mrBC) patients who received personalized peptide vaccine (PPV) therapy (Toh U, SABCS 2015). The prognostic effect was additionally evaluated by the clinical relevant factors including intrinsic subtype, the regimens of combined chemo-hormonal therapies in present study.
Methods:We analyzed serum IgG responses to all of the peptide candidates included PRAs (PSA, PAP and PMSA) after PPV therapy by the Luminex systemusing peripheral blood samples from 77 vaccinated mrBC patients. The clinical factors and relevant events were statistically evaluated.
Results: After 6 and 12cycles of PPV therapy, the serum IgG of anti-PSA, anti-PAP, and/or anti-PMSA increased significantly in 31 patients (PRA response group), and the median progression free survival (PFS) and median overall survival (OS) were 8.1 and 14.3 months, but were 5.1 and 10.8 months, respectively, in the remaining 46 patients with no anti-PRA IgG response (PRA non-response Group). The anti-PRA IgG level was marginally correlated withPFS (p=0.059) and OS (p=0.082) between these two groups, which was a significant prognostic factor for PFS (Log-rank: 0.009) in estrogen-positive cancer patients (ER+). The statistical analyses showed that the clinical outcome was in favor of > 60 year-old patients, those with longer PPV therapies (>3 months), and those who received combined standard hormonal therapies or bisphosphonate/anti-RANKL therapy.
Conclusions: This study indicated a clinical significance between the pre-and post- PPV therapy measurement of serum anti-PRA IgG in patients with mrBC, which may be a useful prognostic marker for monitoring peptide vaccine treatment outcomes, particularly for patients > 60 years with ER+ breast cancer. These results also suggest that the immunotherapeutic peptide vaccine could be efficiently combined with hormonal therapy, anti-HER2 therapy, and bisphosphonate/anti-RANKL therapy in mrBC patients.

Abstract
860 Background: In patients with unresectable colorectal cancer, primary tumor resection is expected not only local control but also prolongation of survival time. However, in some cases, metastatic tumors have been known to rapidly progress after primary tumor resection. We examined clinical factors associated with acute metastatic progress after primary tumor resection, and it might lead to worse survival. Methods: We retrospectively analyzed 183 patients who were newly diagnosed with unresectable colorectal cancer in our institution between April 2007 and April 2016. Among all patients, 83 patients received resection of primary tumor without the presence of symptoms. They were divided into progression and non-progression group according to metastatic progression that evaluated CT scan from four to six weeks after surgery. We analyzed clinicopathological factors related to acute progression after primary tumor resection using Cox proportional hazards. Results: After resection of the primary tumor, 25 patients were classified into progression group and 58 patients were classified into non-progression group. In progression group, the median percent change in the sum of the longest diameters of target lesions was 29.6% (10.0-191.7%), and 22 (88.0%) patients showed to have new lesions after resection of the primary tumor. Multivariate analysis revealed LDH (HR 4.44, 95%CI 1.15-18.5, p = 0.02), number of liver metastasis (HR 3.28, 95% CI 1.09-10.0, p = 0.03) and RAS status (HR 3.08, 95% CI 1.05-9.46, p = 0.03) were independent baseline factors associated with acute progression after resection of the primary tumor. The median overall survival (OS) was 12.3 and 27.8 months in progression and non-progression group, respectively. Conclusions: Serum LDH, number of liver metastasis, and RAS mutation were baseline factors associated with acute progression of metastatic tumors after resection of primary tumor in patients with unresectable colorectal cancer. These results indicated that the resection of the primary tumor in patients with these factors might be avoided when they have no clinical symptoms.

Abstract
e12072 Background: The aim of this study was to investigate the correlation of immunologic factors including the expression of PD-1/PD-L1, PTEN, and the density of TILs, macrophages in the tumor area of breast cancer, using immunohistological staining and to evaluate the association between the immunologic factors and the clinical outcome for early breast cancer (EBC). Methods: A total of 97 EBC patients (pts) who underwent surgery from February 1995 to November 2005 were investigated.The postoperative adjuvant chemotherapies were routinely performed, adjuvant Tmab were not available in Japan within this period.The immunohistological staining was performed with the monoclonal antibodies for PD-1/PD-L1, PTEN, CD3, CD8, and CD163. Pathological analysis was performed to measure the expression area of each antibody, using images scanned by a CCD digital camera (Nikon), and the digitized data of the expression area (μm2) were analyzed by ‘Win ROOF’ (version 5.7) software. The association between the immunologic factors and clinical outcome was statistically analyzed for over 10-years follow-up. Results: The density of CD3+TILs, CD8+TILs, CD163+ macrophages and non-expression of PTEN was significantly higher in triple negative breast cancer (TNBC). CD8+TIL density and PD-L1+/CD8+ expression were predictive factors for DFS and OS. Her2+ pts with PTEN expression and luminal/Her2- patients without PD-L1 expression had longer OS, compared to patients without PTEN expression (p=0.049) and with PD-L1 expression (p=0.036), respectively. Furthermore, the pts with PD-L1+/CD8+ expression had worse median PFS (p = 0.022) and median OS (p = 0.037), compared with pts without PD-L1+/CD8+ expression. Conclusions: Our results demonstrated that CD3+ TILs, CD8+ TILs, and CD163+ macrophages were shown to infiltrate the tumor area of EBC. In particular, TNBC had a higher rate of TIL infiltration within the tumor environment. PTEN expression and lack of PD-L1 expression were associated with favorable survival in Her2-positive and luminal/Her2-negative EBC patients, respectively. The PD-L1 expression combined with CD8+ density was significantly associated with an aggressive clinical outcome.

Abstract
The aim of this research was to investigate the correlation of immunologic factors in the tumor environment of breast cancer, using immunohistological staining to evaluate the expression of programmed death 1/programmed death ligand 1 (PD-1/PD-L1), phosphatase and tensin homolog (PTEN), tumor infiltrating lymphocytes (TILs), and macrophages, and to analyze the association between the immunologic factors and clinical outcome for patients with early stage breast cancer (EBC). A total of 97 EBC patients who underwent standard surgery were investigated. Expression of PD-1/PD-L1 and PTEN and the density of CD3+ TILs, CD8+ TILs, and CD163+ macrophages were evaluated by immunohistochemical analysis. The association between the immunologic factors and clinical outcome was statistically analyzed. The density of CD3+ TILs, CD8+ TILs, and CD163+ macrophages and non-expression of PTEN was significantly higher in cases of triple negative breast cancer. CD8+ TIL density and CD8+ /PD-L1+ expression were predictive factors for disease-free survival and overall survival (OS). Human epidermal growth factor 2 (HER2)-positive patients with PTEN expression and luminal/HER2-negative patients without PD-L1 expression had significantly longer OS compared to patients without PTEN expression (P = 0.049) and with PD-L1 expression (P = 0.036), respectively. Furthermore, patients with PD-L1+ /CD8+ expression had worse median progression-free survival (P = 0.022) and median OS (P = 0.037) compared with patients without PD-L1+ /CD8+ expression. The CD3+ TILs, CD8+ TILs, and CD163+ macrophages were shown to infiltrate the tumor area of EBC. In particular, triple negative breast cancer had a higher rate of TIL infiltration within the tumor environment. Expression of PTEN and lack of PD-L1 expression were associated with favorable survival in HER2-positive and luminal/HER2-negative EBC patients, respectively. The PD-L1 expression combined with CD8+ density was significantly associated with an aggressive clinical outcome.

Abstract
The purpose of this study was to retrospectively investigate the outcomes of Brånemark System Mk III TiUnite/Groovy implants placed in patients at Kobe University Hospital. Various risk factors for implant failure, including mechanical coupling, were investigated by univariate and multivariate analysis. The predictive variables investigated included age, sex, smoking habit, general health, history of radiation therapy, application of a dentomaxillary prosthesis, type of prosthesis, use of alveolar bone augmentation, site of implant insertion, mechanical coupling between implants, and the length and diameter of the implants. Of the 907 implants investigated, only 23 were unsuccessful; the overall survival rate was 96.7%. Increased age, radiation therapy, application of a removable prosthesis or dentomaxillary prosthesis, lack of mechanical coupling between implants, and shorter implants (≤8.5mm) were significant risk factors for implant failure according to univariate analysis (P<0.05). Multivariate analysis identified a significant association (P<0.05) between dental implant failure and a lack of mechanical coupling between implants (odds ratio 6.88) and shorter implants (≤8.5mm) (odds ratio 3.43). The findings of this study demonstrated multivariate relationships between various risk factors and dental implant failure.

Abstract
Our previous phase II clinical trial showed that therapeutically selected personalized peptide vaccines(PPVs)were effective at boosting anticancer immunity; the immune response after PPV was associated with a clinical outcome as a prognostic factor for metastatic breast cancer(mBC). We conducted an early phase II study to evaluate the safety and efficacy of a new regimen using multiple peptide vaccines(KRM-19)for patients with metastatictriple -negative breast cancer. KRM-19 consisted of 19 mixed peptides chosen from the previously reported 31 PPVs according to their anti-tumor immunologiceffec ts and safety profiles for patients with mBC. All patients had histologically confirmed measurable ER-PgR-HER2- mBC and their human leukocyte antigen(HLA) / -A molecules were A2, A3, A11, A24, A26, A31, or A33. KRM-19(19mg/mL)was administrated subcutaneously every week for a total of 6 doses. Concurrent conventional chemo- and/or endocrine therapy were not permitted during treatment. This was an open-label, early phase II study. The primary endpoint was safety and anti-tumor immunologic effect, while the secondary endpoints were clinical responses and progression-free survival(PFS). The estimated enrollment was 10-15 and 8 patients were enrolled(Clinical trial registry number: UMIN000014616). Measurement of peptide-specific cytotoxic T lymphocyte and IgG responses were conducted before and after vaccination. The correlation between PFS and the increased IgG response and/or CTL levels were investigated.

Abstract
Direct measurements of seven highly exposed workers at the Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Station accident have been performed continuously since June 2011. Caesium clearance in the monitored workers is in agreement with the biokinetic models proposed by the International Commission on Radiological Protection. After 500 d from the initial measurement, however, the caesium clearance slowed. It was thought to be unlikely that additional Cs intake had occurred after the initial intake, as activity in foods was kept low. And, the contribution from the detector over the chest was enhanced with time. This indicates that insoluble Cs particles were inhaled and a long metabolic rate showed.

Abstract
A novel heparinoid polymer was prepared with an N-sulfate side chain group by sulfation of poly( N-vinylacetamide-co-vinylamine) [poly(NVA-co-VAm)] which was obtained by the partial hydrolysis of poly( N-vinylacetamide) [poly(NVA)]. The hydrolysis of poly(NVA) was controlled by reaction time and temperature and the sulfation of poly(NVA-co-VAm) was performed with chlorosulfonic acid. Poly( N-vinylacetamide-co-vinylamine-co-vinylsulfamic acid) [poly(NVA-co-VAm-co-VSA)] was confirmed by means of IR spectroscopy, and the degree of sulfation of poly(NVA-co-VAm-co-VSA) was estimated by elemental analysis. The anticoagulant properties of poly(NVA-co-VAm-co-VSA) were evaluated using the Lee-White clotting test and activated partial thromboplastin time (APTT) test. The human whole blood clotting time in the presence of poly(NVA-co-VAm-co-VSA) was prolonged compared with poly(NVA) and poly(NVA-co-VAm). The clotting time was prolonged with increased N-sulfate groups on the polymer. APTT tests of the polymer were also prolonged with N-sulfate increases. The results suggest that the N-sulfate components on the polymer can endow anticoagulant activity to synthetic polymers.

Abstract
Anti-TNF-α inhibitors have been widely used in the treatment of inflammatory bowel disease. Although they have good clinical efficacy and tolerance, they remain a matter of concern because they cause drug-induced autoimmune disorders as side effects. Here, we report a case of a patient with Crohn's disease who developed IgA vasculitis after infliximab and adalimumab treatment. A 17-year-old male with Crohn's disease who had received scheduled infliximab treatment for the preceding 19 months complained of purpura on his lower limbs. He was diagnosed with infliximab-induced IgA vasculitis. Switching infliximab to adalimumab resulted in rapid improvement of the condition. However, 21 months after switching to adalimumab, his purpura recurred. Drug-induced IgA vasculitis is a rare complication caused by infliximab and adalimumab; however, diagnosis in the early phase and appropriate management of patients receiving anti-TNF-α inhibitors is critical to a successful patient outcome.

Abstract
Breast carcinoma rarely occurs in cases of foreign body granulomas following liquid silicone injection. Although the Food and Drug Administration (FDA) banned the use of all silicone injection products in 1992, liquid silicone injection for breast augmentation continues to be performed illegally. We herein report a case of breast carcinoma following liquid silicone injection in a 67-year-old female. A total of 45 years after liquid silicone injection, the patient had felt a breast mass in the right breast. Mammography showed a smooth mass that retracted the right nipple. Due to the presence of a marked acoustic shadow caused by the granulomas, evaluating the mass on ultrasonography was difficult. However, magnetic resonance imaging (MRI) showed a lobulated mass under the right nipple. The mass exhibited low signal intensity (SI) on T1-weighted images and intermingled high and low SI on T2-weighted images. Heterogeneous early enhancement with central low intensity was noted on dynamic contrast-enhanced MRI. Several oval-shaped low SI structures in the adipose tissue and disruption of the pectoralis major muscle were also observed. We diagnosed the patient with invasive ductal carcinoma based on a stereotactic-guided Mammotome® (a vacuum-assisted biopsy system manufactured by DEVICOR MEDICAL JAPAN, Tokyo, Japan) biopsy and subsequently performed mastectomy and axillary lymph node dissection (with a positive result for the sentinel node biopsy). Histologically, invasive ductal carcinoma was observed in the silicone granuloma. The development of foreign body granulomas following breast augmentation usually makes it difficult to detect breast cancer; thus, various devices are required to confirm the histological diagnosis of breast lesions. The stereotactic-guided Mammotome® biopsy system may be an effective device for diagnosing breast cancer developing in the augmented breast.

Abstract
Various chemotherapeutic agents used in patients with hematopoietic malignancy cause serious side effects, including myelosuppression and immunosuppression. Immunosuppression makes patients more susceptible to infection, resulting in an increased risk of infectious complications, including the development of severe septicemia that may be life-threatening. It is necessary for dental staff to be familiar with an appropriate protocol in such cases and to share information about the chemotherapy with a hematologist. To verify the effectiveness of our dental intervention protocol, we conducted a prospective study on the incidence of complications for each myelosuppressive grade of chemotherapy in patients with hematopoietic malignancy. We compared the incidence of complications between treatment P (patients who finished all the dental treatments according to the protocol) and treatment Q (patients who did not) per grade (A, B, C, D) and incidence of systemic or oral findings. We also compared the incidence of oral complication related to the residual teeth between first chemo (patients who were undergoing chemotherapy for the first time) and prior chemo (not the first time). There were significant differences in inflammatory complications between treatment P and treatment Q. We found that both systemic and oral inflammatory complications increased with higher-grade myelosuppressive chemotherapy. Additionally, there was a significant difference between the incidence of oral complications related to the residual teeth between first chemo and prior chemo. Complete implementation of the dental intervention protocol was associated with fewer oral and systemic infectious and inflammatory complications in patients with hematopoietic malignancies undergoing chemotherapy. The incidence of oral and systemic complications also increased with grade of chemotherapy. These results support the validity of our dental intervention protocol. We should pay close attention to the oral state of de novo hematopoietic malignancy patients.

Abstract
The diagnosis of NSAID-induced colon ulcers is difficult when the distribution or endoscopic findings are not typical. An 83-year-old woman was transferred to our hospital for hemorrhagic diarrhea. Colonoscopy showed multiple ulcers in the entire colon, particularly longitudinal ulcers in the transverse colon. These were unusual for NSAID-induced colopathy, although she had been on meloxicam. However, capsule endoscopy revealed multiple scars and erosions, characteristic of NSAIDs users. The final diagnosis was NSAID-induced enteropathy, and all lesions were in remission after meloxicam discontinuation. We herein emphasize the value of an endoscopic assessment of the entire digestive tract in the diagnosis of NSAID-induced mucosal lesions.

Abstract
We investigated changes in the sensitivity of cutaneous points and the oral mucosa after sagittal split ramus osteotomy (SSRO) and assessed the differences between SSRO and intraoral vertical ramus osteotomy (IVRO). The subjects included in this study were 46 patients with mandibular prognathism who underwent IVRO (88 rami) and 30 patients who underwent SSRO (59 rami). An objective evaluation of the neurosensory status of each patient was completed preoperatively and at 1, 4, 8, 12, and 24 weeks postoperatively. Other variables studied for each patient included sex, age, magnitude of mandibular setback, and amount of blood loss during surgery. We found that a neurosensory recovery occurred earlier in the oral mucosa than at cutaneous points. The number of oral mucosa points showing reduced neurosensory function and neurosensory disturbance after SSRO was significantly higher than after IVRO at 1, 4, and 8 weeks (P<0.05). The nerve recovery observed after SSRO was delayed for a longer period than that noted in our previous study of IVRO. In conclusion, we found changes in sensitivity at cutaneous points and the oral mucosa after SSRO and assessed the differences between SSRO and IVRO.

Abstract
We report the case of a 60-year-old male patient who was diagnosed with metastasis from primary lung cancer to the breast. The patient presented with a mass in the right breast. Mammography, ultrasound, and magnetic-resonance imaging each suggested primary breast cancer. A core-needle biopsy of the right breast mass indicated poorly differentiated adenocarcinoma. A basic chest X-ray showed a shadow in the left upper lung. Thoraco-abdominal computed tomography revealed a mass with a diameter of 90 mm in the left superior region, the shape of which was indicative of primary lung cancer. A lung biopsy confirmed poorly differentiated adenocarcinoma. We diagnosed primary lung cancer with metastases to the bone, brain and right breast (cT2N3M1, stage IV) by imaging and histopathology. He was administered carboplatin (area under the curve 6 mg / ml) and paclitaxel (200 mg / m(2)) tri-weekly, and underwent gamma-knife treatment for the brain metastasis. The treatments reduced the primary tumor and the metastases. However, after completion of the fifth treatment cycle, he developed disseminated intravascular coagulation from septic shock, and died on the eleventh day after completing the fifth cycle of treatment. Although metastasis to the mammary gland is uncommon, especially among males, metastasis to the mammary gland should be considered when a mammary mass does not exhibit the typical characteristics of breast cancer. A correct diagnosis of metastasis to the mammary gland from lung cancer makes it possible to select the most appropriate treatment method.

Abstract
PURPOSE Although oral dryness is a predictor for oral mucositis caused by Chemoradiotherapy (CRT) for head and neck cancer, there have been few reports evaluating the sequential changes in oral dryness during therapy. Studies have determined the reliability and usefulness of a moisture-checking device for the evaluation of dry mouth. This study aimed to evaluate the oral moisture level in patients with Oropharyngeal Cancer (OPC) during CRT using a moisture-checking device. METHODS Oral moisture level was measured with an oral moisture-checking device (Moisture Checker Mucus®) at the lingual and buccal mucosa before, at the midpoint, and at the end of CRT in patients with OPC. Sequential changes in oral dryness were evaluated. RESULTS A significant decrease in oral moisture level at the lingual mucosa was found when comparing values before and at the end of CRT (P=0.017). Decreases in oral moisture level at the buccal mucosa were not significant. CONCLUSIONS A moisture-checking device is considered a useful tool for determining the sequential changes in oral dryness during CRT for head and neck cancer. Our findings provide a basis for future larger long-term studies of oral moisture levels in OPC patients receiving CRT.

Abstract
PURPOSE We compared the safety, invasiveness and cosmetic outcomes between endoscopic breast-conserving surgery (endoscopic group) and surgery under direct vision (direct vision group) for treating breast cancer. METHODS We compared 100 cases of endoscopic surgery with 150 cases of direct vision surgery. The safety was evaluated in terms of the blood loss, length of the operation and presence or absence of complications, whereas the degree of invasiveness was assessed using preoperative and postoperative leukocyte counts, neutrophil counts, interleukin (IL-6) levels and fever. The cosmetic outcome was assessed on the basis of a breast evaluation by the medical staff and the patient's subjective satisfaction. RESULTS In both groups, serious postoperative complications were absent. No significant differences were observed in the leukocyte counts, neutrophil counts, IL-6 level or fever between the groups. An evaluation of the cosmetic outcomes by the staff showed a more favorable breast size, breast shape and scar condition in the endoscopic group. A significantly higher level of patient satisfaction was also observed in the endoscopic group. Postoperative local recurrence was absent. CONCLUSIONS The endoscopic approach showed comparable safety and invasiveness, and provided better postoperative cosmetic outcomes than direct vision surgery. Our results suggest that endoscopic breast-conserving surgery is a potentially useful surgical method for the treatment of breast cancer.

Abstract
BACKGROUND Patients allergic to pollen have been known to become more symptomatic during pollen season compared with the nonpollen season. However, there are few studies regarding whether higher exposure to pollen might increase the prevalence of allergic diseases. METHODS An ecological analysis was conducted to evaluate whether pollen exposure is associated with the prevalence of allergic diseases in schoolchildren. Pollen count data of Japanese cedar (Cryptomeria japonica) and Japanese cypress (Chamaecyparis obtusa), which are the major pollen allergens in Japan, were obtained from each prefecture. The prevalence of allergic diseases in schoolchildren in each prefecture was based on a nationwide cross-sectional survey using the International Study of Asthma and Allergies in Childhood questionnaire. RESULTS After omitting three prefectures where pollen data were not available, data of 44 prefectures were analysed. The prevalence of allergic rhinoconjunctivitis in children aged 6-7 years was positively associated with both cedar and cypress pollen counts (P = 0.01, both), whereas the prevalence of allergic rhinoconjunctivitis in children aged 13-14 years was positively associated with only cypress pollen counts (P = 0.003). Furthermore, the prevalence of asthma was positively associated with cedar pollen counts in 6- to 7-year-old children (P = 0.003) but not cypress pollen counts in either age group. CONCLUSIONS There are ecological associations between pollen counts and the prevalence of allergic diseases in Japanese schoolchildren. Further studies are needed to determine whether the difference between the effects of cedar and cypress pollens is attributable to pollen counts or allergenicity.

Abstract
A 62-year-old woman being treated for chronic hepatitis C and high blood pressure was shown by computed tomography to have tumors in the lateral and medial segments of her liver, and in her right breast. The tumor in the lateral segment of the liver was excised, the tumor in the medial segment of the liver was treated with microwave coagulation therapy, and the breast tumor was treated with simple mastectomy and sentinel lymph-node biopsy. Based on pathological features, the liver tumors were classified as moderately differentiated liver cell carcinoma, and the breast tumor as estrogen receptor-negative, progesterone receptor-negative, and human epidermal growth factor receptor-2-positive ductal carcinoma. Hepatic arterial infusion chemotherapy using fluorouracil and cisplatin with trastuzumab as an adjuvant was administered to treat both cancers simultaneously. Twelve months after the operation, neither of the cancers had relapsed. This case suggests that when the breast cancer is human epidermal growth factor receptor-2-positive, trastuzumab should be administered as adjuvant therapy.
