To investigate the relationship of dental status to food diversity among older Japanese.A community-based cross-sectional study conducted in the town of Tosa, Kochi Prefecture, Japan.The study participants were 252 Japanese (84 men and 168 women, average age 81.2 years) and dentate participants were classified into three groups: 1-9 teeth, 10-19 teeth and 20 or more teeth. Food diversity was assessed as a validated measure of dietary quality using the 11-item Food Diversity Score Kyoto (FDSK-11), which evaluates frequency of consumption of 11 main food groups. Multivariable analysis of the differences in FDSK-11 score ranging from 0 to 11, with a higher score indicating greater food diversity, among the three dental status groups was conducted using general linear models. All the performed analyses were stratified by gender.There was no association between dental status and food diversity score in models for men. In contrast, women with ≤ 9 teeth and with 10-19 teeth had significantly lower FDSK-11 scores than women with ≥ 20 teeth after adjusting for confounders (p0.001 and p = 0.009, respectively). Additionally, there was a trend toward lower scores for FDSK-11 with fewer teeth (p = 0.001).A less varied diet, as indicated by low FDSK-11 score, was observed in female participants with fewer teeth. Tooth loss was associated with poor diet quality among older Japanese women.

The purpose of this report is to document the presence of dimethyl sulfide in mouth air as the predominant volatile sulfur compound (VSC) in an asthmatic patient who was regularly taking suplatast tosilate.The patient was a 33-year-old woman who complained of bad breath. She had been diagnosed as having asthma and was receiving periodical medical examinations once a month. VSC in her mouth air were measured with a gas chromatograph. Oral physiotherapy was also carried out to remove any oral malodor of which the source was intraoral.With the improvement in oral hygiene and periodontal conditions, the level of VSC was reduced but dimethyl sulfide still remained as the predominant VSC.Dimethyl sulfide metabolized from suplatast tosilate may be a potential cause of halitosis.

Result and problems were studied in 12 patients who received percutaneous cardiopulmonary support (PCPS) after cardiac or aortic surgery. Causative diseases included acute myocardial infarction in 7 cases, rupture of the left ventricular septum after infarction, acute mitral valve regurgitation after infarction, rupture of the left ventricular free wall, a stuck valve, and an aortic aneurysm in the thoracicoabdominal region in each 1 case. The time of postoperative PCPS ranged from 2 to 361 hours, and the mean supply flow volume was 1.78 +/- 0.45 l/min/m2. Seven patients could be taken off the treatment or discharged from the hospital (58.3%). The comparison between surviving and non-surviving cases showed a significantly longer assisted circulation time in the latter. An increase of bleeding after surgery was found in all 8 patients who received PCPS for a long period postoperatively. This was assumed to be due to the thrombocytic activation by heparin.

A 51-year-old woman admitted to our hospital. Chest X-ray film showed infiltrations in left S4 region, which had been pointed out since two years before. On exploratory thoracotomy, lingual segmentectomy was performed because no metastatic lesions were found in the mediastinal and hilar lymph nodes. Pathological and immunohistological examinations revealed findings corresponding to pulmonary malignant lymphoma (diffuse, small cell type, B cell) with amyloid plaque. The patient is doing well 20 months after operation without any signs of recurrence. The clinical and histological findings of this case may suggest a close relationship between malignant lymphoma and production of amyloid.

A 70-year-old female was referred to our hospital because of swelling at her frontal neck and an abnormal shadow on a chest X-ray film. CT scan and MRI showed a 11.0 x 7.5 cm well-demarcated tumor in the upper mediastinum. Thyroidal scintigraphy revealed an slight accumulation, leading to a diagnosis of intrathoracic goiter. During operation the mass was found to be composed of two tumors. The upper tumor was attached with fibrous adhesion to the right lobe of cervical thyroid but no connection. Histological examination showed follicular but not malignant adenoma of the thyroid.

It was examined whether the tannin-fluoride preparation (HY preparation), which might have a caries-reductive, plaque inhibiting and astringent action, could reduce the incidence of gingival inflammation around abutment teeth. Zinc oxide eugenol cement mixed with the HY preparation was packed in the cavity prepared in the resin base facing the abutment tooth. Gingival crevicular fluid (Periotron units:GCF), gingival index (GI), plaque index (PlI) and probing depth around the abutment teeth were measured over a 3 month period. The following results were obtained: 1. GCF decreased at month 1 and showed low values at months 2 and 3. 2. GI showed a decreasing tendency. 3. PlI and probing depth did not show obvious changes. These results indicate that the tannin-fluoride preparation reduces gingival inflammation around abutment teeth.

A case of left ventricular-right atrial (LV-RA) communication associated with a false aneurysm of membranous septum is presented. The patient was a 51-year-old woman. Using a left ventriculography this case was diagnosed preoperatively as LV-RA communication. We found that the right atrium was directly communicated with the left ventricle through a fibrous membranous aneurysm adhering to the septal leaflet of the tricuspid valve. It was suggested that a false aneurysm, made by jet lesion from the left ventricle, perforated to the right atrium. So the current case was considered an acquired infravaluvular type LV-RA communication formed in the course of the natural closure of the membranous ventricular septal defect.

Sixty subjects (42 subjects with dentures and 18 subjects without dentures) participated in this study. Crevicular fluid flow (Periotron unit: CGF), gingival index (GI), plaque index (P1I) and probing depth (PD) of 209 marginal gingiva around the proximal surface area adjacent to the edentulous space of natural and crowned abutment teeth were measured to evaluate gingival health. The following results were obtained. 1. The GI, P1I and PD in the subjects with dentures were higher than those in the subjects without dentures. The GCF in the subjects with dentures was inclined to be higher when compared to that in the subjects without dentures. 2. In the subjects with dentures, the GCF, GI and PD of crowned teeth were higher than those of natural teeth. On the other hand, in the subjects without dentures, the GCF, GI and PD of crowned teeth were almost equal to those of natural teeth.
