A Case Report of Atypical Spindle Cell Lipomatous Tumor of the Tongue
Herein, we report a case of atypical spindle cell lipomatous tumor (ASCLT) on both sides of the tongue in a 74-year-old male patient. The patient was referred to our department for treatment of the masses in the tongue. Several elastic soft indolent masses were detected during the first examination. The masses were well defined, and their consistency was similar to that of adipose tissues. No signs of induration were observed in the surrounding tissues. The patient was not aware of the masses, which were only detected during his visit at the dental clinic that referred him to our institution. Thus, the onset of the masses remains unknown. ASCLT was identified via histopathological examination. Then, tumor excision was performed under general anesthesia. Thirteen months after surgery, the condition of the patient was good, and signs of local recurrence or postoperative metastasis were not observed
Geometric and Electronic Structures of Dibenzo-15-Crown-5 Complexes with Alkali Metal Ions Studied by UV Photodissociation and UV-UV Hole-Burning Spectroscopy
We measure UV photodissociation (UVPD) and UV-UV hole-burning (HB) spectra of dibenzo-15-crown-5 (DB15C5) complexes with alkali metal ions, M+•DB15C5 (M = Li, Na, K, Rb, and Cs), under cold (~10 K) conditions in the gas phase. The UV-UV HB spectra of the M+•DB15C5 (M = K, Rb, and Cs) complexes indicate that there is one dominant conformation for each complex except the Na+•DB15C5 complex, which has two conformers with a comparable abundance ratio. It was previously reported that the M+•(benzo-15-crown-5) (M+•B15C5, M = K, Rb, and Cs) complexes each have three conformers. Thus, the attachment of one additional benzene ring to the crown cavity of benzo-15-crown-5 reduces conformational flexibility, giving one dominant conformation for the M+•DB15C5 (M = K, Rb, and Cs) complexes. In the UVPD spectra of the K+•DB15C5, Rb+•DB15C5, and Cs+•DB15C5 complexes, the S1–S0 and S2–S0 transitions are observed independently at different positions with different vibronic structures. The spectral features are substantially different from those of the K+•(dibenzo-18-crown-6) (K+•DB18C6) complex, which belongs to C2v point group and exhibits the exciton splitting with an interval of 2.7 cm–1. The experimental and theoretical results suggest that in the M+•DB15C5 complexes the two benzene rings are not symmetrically equivalent with each other, and the S1–S0 and S2–S0 electronic excitations are almost localized in one of the benzene rings. The electronic interaction energy between the two benzene chromophores is compared between the K+•DB15C5 and K+•DB18C6 complexes by quantum chemical calculations. The interaction energy of the K+•DB15C5 complex is estimated to be less than a half of the K+•DB18C6 complex (~30 cm–1) due to less suitable relative angles between the transition dipole moments of the two benzene chromophores in K+•DB15C5.This work was partly supported by JSPS KAKENHI Grant Number 16H04098
A Case of Psoriasis Complicated by Breast Cancer after Systemic Treatments Including Biologics
Psoriasis is a common chronic inflammatory skin disorder that is characterized by scaly, erythematous, sharply demarcated plaques. The treatment for psoriasis has dramatically changed over the last 10 years with the introduction of biologics. However, the risk of cancer induced by biologics for psoriasis has not been fully analyzed, since these agents have such a short history of use. Here we report the case of a 74-year-old woman with psoriasis vulgaris and psoriatic arthritis complicated by breast cancer after systemic treatments including etretinate, cyclosporine, methotrexate, adalimumab, and ustekinumab
Usefulness of the Measurement of Fractional Exhaled Nitric Oxide in Asthmatic Patients :Correlation with Pulmonary Function, Asthma Control and Health Status
Background and objective:This study was conducted to investigate whether or not FeNO correlates with lung function tests, the Asthma Control Test (ACT) for assessing asthma control or the Asthma Health Questionnaire (AHQ-33) for evaluating the health status in asthmatics. Methods :FeNO was compared with the results of spirometry,ACT and AHQ-33 in 57 non-smoking patients with asthma and 17 healthy individuals without pulmonary diseases who had never smoked. Sixteen of 57 asthmatics treated with inhaled corticosteroid (ICS)underwent step-down therapy if they showed good/total control or step-up therapy if they showed poor control, and were evaluated by spirometry, ACT and AHQ- 33 prior to and more than one month after starting step-down or step-up therapy. Results :FeNO in asthmatics was significantly higher than that in the control group.There were no significant correlations between FeNO and FEV1, ACT score or AHQ-33 scores. However, there were significant correlations between the changes in FeNO and changes in FEV1, ACT score or AHQ-33 scores following stepdown or step-up therapy. Conclusion :FeNO is a useful marker not only for the diagnosis of asthma but also for asthma control and determining the health status in an individual patient, although it is variable without any correlation with symptoms and lung function among asthmatics.

Correlation between 18F-fluorodeoxyglucose Positron Emission Tomography/computed Tomography and Clinicopathological Features in Invasive Ductal Carcinoma of the Breast
We evaluated the usefulness of preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) examinations to predict the pathological features in primary breast cancer. In particular, we evaluated the correlation between the maximum standardized uptake values (SUVmax) obtained by 18F-FDG PET/CT and the Ki67 expression in estrogen receptor (ER)-positive invasive ductal carcinoma (IDC). Primary IDC patients operated between March 2009 and July 2013 at Okayama University Hospital were enrolled. We evaluated the correlations between the SUVmax and age, postoperative pT, histological grade, lymph vascular invasion, status of hormone receptor, human epidermal growth factor receptor 2 (HER2), Ki67 expression and node status. The Ki67 expression was classified as high (>14%) versus low (<14%). We enrolled 138 patients with IDC. Their median SUVmax was 3.85 (range:0-52.57). In a univariate analysis, the SUVmax was significantly related to age, pT, histological grade, lymphovascular invasion, hormone receptor status, HER2 status, node status and Ki67. In the 113 patients with ER-positive IDC, there was a significant correlation between Ki67 and SUVmax (p=0.0030). The preoperative 18F-FDG PET/CT results of IDC patients had significant relationships with pathological status parameters. The determination of the preoperative SUVmax might help classify Luminal A and Luminal B patients among luminal-type breast cancer patients
