Abstract
This case report describes common oral inflammatory findings leading to the identification of Chédiak-Higashi syndrome (CHS). A 15-year-old girl presented with an enlarging and painful mass on the upper lip. Two weeks after the initial visit, the mass showed further protrusion in the absence of fever. Magnetic resonance imaging revealed a well-circumscribed cystic lesion with a thick capsule, and suggested an abscess derived from the mucous cyst in the upper lip. Inflammation indices were not elevated; however neutrophils were significantly lower than the normal level. Giant cytoplasmic granules in neutrophils, eosinophils, and lymphocytes, which are pathognomonic of CHS, were noted. The patient displayed brownish-red hair with some grey hair, and partial oculocutaneous albinism. Hepatosplenomegaly was evident on ultrasonography. The final diagnosis was of an oral infection facilitated by the adolescent form of CHS (gene CHS1/LYST at 1q42.1-2). This report offers a reminder that lip swelling may represent the initial manifestation of the inflammatory response in a patient with loss of immunocompetence due to pathologies such as CHS, and may rarely present as the patient's main complaint.

Abstract
As for the HER2-positive breast cancer, there are many cases to be effective for neoadjuvant chemotherapy in comparison with other intrinsic subtypes. However, pCR is not provided by neoadjuvant chemotherapy in all cases. [Aim] This study evaluated the effectiveness of a therapeutic strategy that switches chemotherapy, based on Ki-67 tumor expression after initial therapy, relative to that of standard chemotherapy in patients with HER2-positive breast cancer. [patients and methods] Patients were randomly assigned to the control arm or the Ki-67 response-guided arm (Ki-67 arm). Primary tumor biopsies were obtained before treatment, and after three once-weekly doses of paclitaxel and trastuzumab to assess the interim Ki-67 index. In the control arm, paclitaxel and trastuzumab was continued for a total of 12 doses, regardless of the interim Ki-67 index. In the Ki-67 arm, subsequent treatment was based on the interim Ki-67 index. Early Ki-67 responders continued to received paclitaxel plus trastuzumab for a total of 12 doses, while early Ki-67 non-responders were switched to epirubicin plus cyclophosphamide every 3 weeks for three cycles with once-weekly trastuzumab for a total of 12 doses. The primary endpoint was the pathological complete response (pCR) rate. [Results] When 237 patients were enrolled, an interim analysis was conducted in 200 patients. There was almost linear correlation between the Ki-67 reduction rate at interim assessment and the pCR rate. The pCR rate in Ki-67 early non-responders in the Ki-67 arm (23.6%; 95% CI, 12.4 to 34.9) was inferior to that in the control arm (44.1%; 31.4 to 56.7; p=0.025). A strong correlation was not found between the Ki-67 reduction rate and the clinical response rate (Spearman's correlation coefficient 0.22).

The standard chemotherapy protocol remains as the recommended strategy for patients with HER2-positive breast cancer.

Abstract
BACKGROUND Parkinsonism is often observed in the elderly. To clarify the prevalence of parkinsonism-associated diseases and conditions, we conducted a population-based study in a rural island town in western Japan, Ama-cho. METHODS Participants included 924 subjects aged 65 years or older residing in the town. Between 2008 and 2011, participants were assessed via standardized neurological examination scales, and Brain MRIs were carried out in 2010. Based on the results of assessment using the modified Unified Parkinson's Disease Rating Scale and a standardized neurological examination, participants were diagnosed as having parkinsonism or mild parkinsonian signs (MPS), or as displaying normal motor conditions (M-normal). RESULTS Of the 729 participants screened, 70 subjects were diagnosed as having parkinsonism, corresponding to a crude prevalence rate of 9.6% (95% CI, 7.9-11.3%), while 167 MPS subjects (22.9%) and 492 subjects experiencing M-normal (67.5%) were observed. Parkinsonism was found in association with various diseases such as Vascular parkinsonism, Lewy body disease, Alzheimer's disease (AD), and idiopathic normal-pressure hydrocephalus. Among the subjects with dementia, the proportion with parkinsonism was higher in the non-AD dementia group. CONCLUSION(S) Parkinsonism occurs in association with several diseases in elderly people. Parkinsonism was also found to be commonly associated with cognitive impairment.

Abstract
Abstract
Background: There are few randomized clinical trials examining adjuvant treatment in elderly breast cancer patients. While obtaining informed consent is essential for participation in clinical studies, there is little information on the frequency of agreement to participate among elderly patients. Furthermore, elderly patients might have specific reasons to decline participation.
Patients and Method: The National Surgical Adjuvant Study of Breast Cancer 07 (N-SAS BC 07) is a randomized clinical trial in women over 70 years with HER2-positive primary breast cancer. The primary aim was to investigate the benefit of trastuzumab monotherapy compared with the combination of trastuzumab and chemotherapy. Key inclusion criteria were as follows: women between 70 and 80 years old with HER2-positive breast cancer; underwent curative operation; stage I to IIIA; with sufficient organ function. Patients were randomized to receive either trastuzumab plus chemotherapy or trastuzumab monotherapy. The primary endpoint was disease-free survival, and the secondary endpoints were overall survival, relapse-free survival, safety, health-related quality of life, and cost effectiveness (NCT01104935). It was not possible to predict the number of patients who would agree to participate. In order to comprehensively assess the effect of postoperative adjuvant therapy, we evaluated the reasons why eligible patients declined to participate. The patients were registered in a cohort study to prospectively evaluate the subsequent treatment options and prognosis (07-Cohort). This study examined the obtaining of informed consent for N-SAS BC 07 and the reasons for declining participation, and compared the clinicopathological backgrounds between the N-SAS BC 07 and 07-Cohort groups.
Results: 398 eligible patients have been recruited. Informed consent to participate in N-SAS BC 07 has been obtained from 275 patients (69%) and 123 patients (31%) who declined to participate in the RCT have been registered in the 07-Cohort. The common reasons to decline participation in the RCT were "cannot choose the treatment option (55%)", "refused chemotherapy (16%)", "wanted chemotherapy (9%)", "anxious about clinical studies (9%)" and "family opposition (8%)". The mean ages of the patients in N-SAS BC 07 and 07-Cohort were 73.9 and 74.6 years old, respectively. There were no differences in stage, surgical procedure, lymph node metastasis, or co-morbidities between the groups. ER-positive rate was higher in 07-Cohort group compared with N-SAS BC 07 group (53% vs. 37%, p=0.017, χ2 test).
Conclusion: While we expected the number of registrants to be small, since N-SAS BC 07 investigated whether elderly patients with HER2-positive breast cancer should undergo chemotherapy, almost 70% of the patients accepted informed consent. The most common reason to decline participation in N-SAS BC 07 was "cannot choose the treatment option" and the majority refused chemotherapy. Furthermore, ER-positivity was higher in the 07-Cohort group, which suggested that ER expression in the patients with HER2-positive breast cancer might influence their decision to participate in the study or to choose the treatment option.

Abstract
Abstract
Background: Health-related quality of life (HRQoL) is one of the important outcomes in cancer control trials and has increasingly become the one of the primary foci. Obtaining informed consent from participants is essential for participation in randomized controlled trials (RCTs), but the participation in these RCTs may directly influence HRQoL, because treatment options are determined according to the allocation schedule. To date, only a few studies have compared HRQoL between clinical trial participants and decliners.
Patients and Method: The National Surgical Adjuvant Study of Breast Cancer 07 (N-SAS BC 07) is a randomized controlled trial in women with HER2-positive primary breast cancer who are over 70 years of age. The primary aim was to investigate the benefit of trastuzumab monotherapy compared with combination therapy using trastuzumab and chemotherapy. The study concept and design were published in concept paper (Sawaki M. et al., Jpn J Clin Oncol. 2011). In this study, patients were randomized to receive either trastuzumab plus chemotherapy or trastuzumab monotherapy. The primary endpoint was disease-free survival, and the secondary endpoints were overall survival, relapse-free survival, safety, HRQoL, comprehensive geriatric assessment (CGA) and cost effectiveness (protocol ID; NCT01104935).
HRQoL and CGA were assessed at registration (baseline), 2 month, 1 year, and 3 years after the start of protocol treatments using the Functional Assessment of Cancer Therapy-General (FACT-G), Hospital Anxiety and Depression Scale (HADS), EuroQol 5 Dimension (EQ-5D), Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence, and the Philadelphia Geriatric Center (PGC) Morale Scale.
The patients who declined to participate in N-SAS BC 07 were registered in a cohort study to prospectively evaluate the subsequent treatment options and prognosis (07-Cohort). The same questionnaire that was used in N-SAS BC 07 was used in 07-Cohort to evaluate HRQoL and CGA at entry.
Results: Patients were enrolled from October 2012 to October 2016. During this period, 275 and 123 patients were registered in N-SAS BC 07 and 07-Cohort, respectively. The mean age at entry of the patients in the N-SAS BC 07 and 07-Cohort groups was 73.9 and 74.6 years, respectively. The questionnaire response rates at baseline in the patients in N-SAS BC 07 and 07-Cohort groups were 89% and 82%, respectively. There were no significant differences in FACT-G, HADS, EQ-5D, or TMIG index of competence at baseline between the groups, but the mean (standard deviation) scores of PGC Morale Scale in N-SAS BC 07 and 07-Cohort groups were 10.8 (3.3) and 9.9 (3.7), respectively, with the scores being significantly greater in the N-SAS BC 07 group (p=0.020, t-test).
Conclusion: The PGC Morale Scale provides a multidimensional approach to assess the psychological state of older people. This study indicated that participation in the RCT did not affect the baseline QoL of elderly patients but suggested that the baseline QoL of the RCT participants was better than decliners.

Abstract
Background Barber-Say syndrome (BSS) is a very rare congenital disorder characterized by macrostomia, cutis laxa, and other features. We report our experience of performing general anesthesia on a Japanese child with BSS. Case presentation A bilateral repair of the corners of the mouth under general anesthesia was planned for an 18-month-old male with macrostomia; the child was 75 cm in height and weighed 9.9 kg. As insertion of the peripheral intravenous catheter was difficult, it was inserted before the surgery by a pediatrician. The patient wore a mask and was ventilated manually after loss of consciousness with intravenous anesthesia. A mask for adults provided a superior fit and was effective in preventing air leakage from the corners of the mouth. After rocuronium was administered, the larynx was spread with a Macintosh laryngoscope. There was no laryngeal anatomical abnormality, and tracheal intubation was readily possible. The operation was completed without incident. Stiffening of both arms occurred for several seconds one hour after the operation ended, but the patient did not develop other complications. Conclusions Mask ventilation and the insertion of an intravenous catheter may be difficult in the general anesthesia of patients with BSS, and anesthetic management requires caution.

Abstract
OBJECTIVES Mild parkinsonian signs (MPS) are reported to be associated with increased risk of dementia, Parkinson's disease, parkinsonism, and vascular lesions of white matter and are also a significant predictor of mortality. Although more than 20% of subjects aged 60 years and older suffer from MPS in Japan, it is often unrecognized and underestimated by patients and medical physicians. We used neuropsychological methods to examine cognitive function and depressive symptoms in subjects with MPS. METHODS We performed a population-based study in Ama-cho, a rural island town in western Japan. Participants included 951 subjects aged 65 years and older, 613 of whom completed all questionnaires, neurological examinations, and neuropsychological assessments and were included in the data analysis. Subjects were assessed for depression and subjective cognitive impairment using the Geriatric Depression Scale (GDS-15), Mini-Mental State Examination (MMSE), Clinical Dementia Rating (CDR), and modified Unified Parkinson's Disease Rating Scale (mUPDRS). RESULTS Of the 613 participants, 143 were diagnosed with MPS. GDS scores were significantly higher in the MPS group compared with the motor control group, while MMSE scores were significantly lower. CONCLUSIONS We demonstrated that MPS correlate with both depressive symptoms and cognitive impairment.

Abstract
Abstract
Background: Four cycles of doxorubicin plus cyclophosphamide (4-AC) followed by four cycles of a taxane is widely used for postoperative chemotherapy in breast cancer (BC). Concern about relatively rare, but life-threatening toxicity of anthracyclines such as heart failure and secondary leukemia has promoted research to seek anthracycline-free regimens. Since 1990's when taxanes were introduced, docetaxel (DTX) is used interchangeably with paclitaxel (PTX) for the treatment of BC, but they may differ more than initially anticipated. We conducted this trial to test two hypotheses: (1) Eight cycles of a taxane is not inferior to 4-AC followed by four cycles of a taxane; (2) one taxane is superior to the other.
Methods: Eligibility included a diagnosis of clinical stage I-IIIA and axillary node-positive BC, an age younger than 71 years and with performance status of 0 to 1. Patients were randomly assigned to receive either one of the following regimens;ACP: 4-AC (doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2 q3w x 4) followed by 4-PTX (175 mg/m2 q3w x 4)ACD: 4-AC followed by 4-DTX (75 mg/m2 q3w x 4)8-PTX: PTX (175 mg/m2 q3w x 8)8-DTX: DTX (75 mg/m2 q3w x 8)
Comparisons included PTX vs. DTX (ACP + 8-PTX vs. ACD + 8-DTX) and +AC vs. -AC (ACP + ACD vs. 8-PTX + 8-DTX). The primary endpoint was disease-free survival (DFS), and the secondary endpoints include overall survival (OS). The trial was powered to prove the non-inferiority of +AC to -AC (threshold hazard ratio 1.32) in terms of DFS. DFS was also compared between PTX and DTX to determine any superiority.
Results: A total of 1,060 eligible patients were accrued at 84 centers between December 2001 and April 2006. There were 348 DFS events and 166 deaths after a median followup of 72.2 months. DTX was superior to PTX in terms of both DFS (Hazard ratio(HR) 0.76; 95% Confidence Interval(CI) 0.62−0.95, p=0.012) and OS (HR 0.72;95%CI 0.53−0.97, p=0.033). -AC was not inferior to +AC with respect to DFS (HR: 1.21, 90% CI 1.01−1.44). Among the four arms, 8-PTX alone resulted in poorer DFS (compared with ACP, HR 1.42 95%CI 1.07−1.89).
Nausea and vomiting were more frequent with +AC than -AC. Edema and febrile neutropenia were more frequent with DTX than PTX. The incidence of sensory neuropathy was higher with PTX than DTX and it lasted for more than one year of the end of PTX treatment.
Conclusions: When AC, PTX and DTX were given every three weeks, both DFS and OS were better in the arms including DTX than in those including PTX. AC followed by a taxane can be replaced by 8-DTX.

Abstract
The dynamic behavior and kinetics of the structural transformation of supported bimetallic nanoparticle catalysts with synergistic functions in the oxidation process are fundamental issues to understand their unique catalytic properties as well as to regulate the catalytic capability of alloy nanoparticles. The phase separation and structural transformation of Pt(3)Sn/C and PtSn/C catalysts during the oxidation process were characterized by in situ time-resolved energy-dispersive XAFS (DXAFS) and quick XAFS (QXAFS) techniques, which are element-selective spectroscopies, at the Pt L(III)-edge and the Sn K-edge. The time-resolved XAFS techniques provided the kinetics of the change in structures and oxidation states of the bimetallic nanoparticles on carbon surfaces. The kinetic parameters and mechanisms for the oxidation of the Pt(3)Sn/C and PtSn/C catalysts were determined by time-resolved XAFS techniques. The oxidation of Pt to PtO in Pt(3)Sn/C proceeded via two successive processes, while the oxidation of Sn to SnO(2) in Pt(3)Sn/C proceeded as a one step process. The rate constant for the fast Pt oxidation, which was completed in 3 s at 573 K, was the same as that for the Sn oxidation, and the following slow Pt oxidation rate was one fifth of that for the first Pt oxidation process. The rate constant and activation energy for the Sn oxidation in PtSn/C were similar to those for the Sn oxidation in Pt(3)Sn/C. In the PtSn/C, however, it was hard for Pt oxidation to PtO to proceed at 573 K, where Pt oxidation was strongly affected by the quantity of Sn in the alloy nanoparticles due to swift segregation of SnO(2) nanoparticles/layers on the Pt nanoparticles. The mechanisms for the phase separation and structure transformation in the Pt(3)Sn/C and PtSn/C catalysts are also discussed on the basis of the structural kinetics of the catalysts themselves determined by the in situ time-resolved DXAFS and QXAFS.
