A 64-year-old woman with an atrial septal defect (ASD) closure was referred to our hospital ; she presented with dyspnea at the time of admission. An echocardiogram showed mitral valve regurgitation, tricuspid valve regurgitation, and a residual ASD shunt. Coronary angiography revealed coronary-pulmonary artery fistulae originating from both the left anterior descending coronary artery and the right coronary artery (RCA). Closure of the coronary-pulmonary artery fistulae was performed in addition to mitral valve replacement, tricuspid valve plasty and ASD closure. The postoperative course was uneventful. Coronary angiography was performed, and some of the contrast medium remained in parts of the RCA fistulae. Ligation of the fistulae and direct closure of the intra-pulmonary openings during cardiopulmonary bypass had to be performed because of complete obstruction of the coronary-pulmonary artery fistulae.

Papillary fibroelastoma is a rare, benign heart tumor. We successfully treated a patient with multiple fibroelastomas derived from both the mitral valve and the chordae by surgical excision. A 59-year-old man was admitted to our hospital with a history of myocardial infarction three years before admission. Preoperative transthoracic and transesophageal echocardiograms showed multiple, mobile, rounded cardiac tumors in the left ventricular cavity and the mitral valve. Under cardiopulmonary bypass, we performed prosthetic mitral valve replacement after excising the valve with the tumor. The patient was discharged and remains asymptomatic. Histologic examination of 6 specimens of the excised tumor confirmed the diagnosis of papillary fibroelastoma. When papillary fibroelastoma is diagnosed, surgical treatment must be considered because of the high risk of embolization.

OBJECTIVES: This postmarketing, observational study evaluated the safety and effectiveness of monthly intravenous (IV) ibandronate in Japanese patients with osteoporosis. METHODS: Eligible patients received monthly IV ibandronate 1mg for 12 months. Adverse drug reactions (ADRs) were evaluated. Changes in bone mineral density (BMD) and bone turnover markers (BTMs) were assessed using matched t-test analysis. Cumulative fracture rates were analyzed by Kaplan-Meier methodology. RESULTS: In total, 1062 patients were enrolled, of whom 1025 (n = 887 women, n = 138 men) were treated. Mean patient age was 77 years. Seventy-five ADRs were reported in 54 patients (5.26%). Four patients (0.39%) experienced serious ADRs, including one case of osteonecrosis of the jaw. Acute-phase reactions occurred in 21 patients (2.04%), and half of them arose after the first ibandronate injection. No new safety concerns were identified. Significant increases in BMD at 12 months relative to baseline were observed at the lumbar spine (4.84%, n = 187; 95% confidence interval [CI], 3.47%–6.21%), femoral neck (2.73%, n = 166; 95% CI, 1.46%–4.01%), and total hip (1.93%, n = 133; 95% CI, 0.80%–3.07%). Significant reductions were observed in all BTMs at 12 months (n = 174 in tartrate-resistant acid phosphatase-5b, n = 101 in procollagen type 1 N-terminal propeptide at baseline). The cumulative incidence of nontraumatic, new vertebral and nonvertebral fractures was 3.16% (95% CI, 2.12%–4.70%). Analyses in women only showed similar results to the overall population. CONCLUSIONS: These findings confirm the favorable safety and consistent effectiveness of ibandronate, and indicate that monthly IV ibandronate would be beneficial in daily practice for the treatment of Japanese patients with osteoporosis.

Background/Aims:
Detailed evaluations of overlapping constipation and gastroesophageal reflux disease (GERD) have not been conducted in Japan. The REACTION-J2 study examined the overlap of these diseases in Japan.
Methods:
This internet-based survey recruited participants from general public survey panels. Questions included demographic and medical data and assessments based on validated measures for constipation and GERD. Associations between background factors affecting constipation/GERD overlap, disease measures, and treatment were also evaluated.
Results:
Among 10 000 survey responses received, functional constipation (Rome IV diagnostic criteria) was reported by 439 participants; chronic constipation (Japanese guidelines) by 3804 participants; and subjective constipation symptoms by 2563 participants. The number of participants with constipation/GERD overlap ranged from 73 to 1533 depending on the criteria used. Regardless of the definition used, all GERD groups had significantly higher odds of being constipated than non-GERD participants: the OR (95% CI) for all 9 combinations of definitions ranged between 1.56 (1.21, 2.01) and 2.67 (2.44, 2.92) (all P ≤ 0.001). Straining, hard stools, and sensations of incomplete evacuation and anorectal obstruction/blockage, according to chronic constipation criteria, were common.Participants with constipation/GERD overlap had poorer quality of life (P < 0.001) and worse GERD symptom scores (P < 0.001). The frequency of abnormal stools was highest (P < 0.001) in the constipation/GERD overlap group. In the overlap group, 52.4% and 26.0% used gastric and constipation medication, respectively.
Conclusion
Individuals with constipation/GERD overlap tend to have worsened symptoms and quality of life.

Background/Aims:
Chronic constipation and lifestyle factors can affect sleep quality. We evaluated the relationship between chronic constipation and sleep in the Japanese population.
Methods:
This cross-sectional internet-based survey included 3000 subjects with constipation, classified according to sleep status (good/poor).Primary endpoints were Bristol stool form scale (BSFS) score and correlations between sleep disorder criteria of the Pittsburgh Sleep Quality Index (PSQI) and sleep status (good/poor sleep). Secondary endpoints included correlations between quality of life (QOL) and mood, medical, lifestyle, and sleep factors.
Results:
The proportion of participants with BSFS category 4 (normal stool) was significantly higher in the good sleep group (P < 0.001). Sleep disturbance (P < 0.05), sleep quality, and duration, use of hypnotic medication, and daytime dysfunction of PSQI (all P < 0.001) significantly correlated with poor sleep. In the poor sleep group, QOL was significantly worse and anxiety and depression levels were significantly higher (allP < 0.001) compared with the good sleep group. Anemia and smoking (both P < 0.05), recent body weight increases, and poor eating habits (all P < 0.001) were significantly higher in the poor sleep group. Male sex, onset associated with change in frequency of stools, sensation of incomplete evacuation for at least 25% of defecations, and manual maneuvers to facilitate at least 25% of defecations correlated with poor sleep.
Conclusions
Subjects with constipation and poor sleep experienced severe symptoms and had poor QOL. These data support the need for a multifocal treatment approach, including lifestyle advice and pharmacotherapy.

A 76-year-old man who suffered from consistent back pain was admitted for anti-hypertensive therapy to strictly manage the early thrombosed acute type A aortic dissection (AAAD). On admission, his blood pressure could not be controlled well ; soon he complained of recurrent severe back pain. The second thoracoabdominal enhanced computed tomography revealed the progression of AAAD from DeBakey type II to type I with thrombosed pseudolumen at the descending thoracic aorta ; therefore, emergent surgical intervention by primary central repair was conducted. Paraplegia was diagnosed eight hours after surgery, then cerebrospinal fluid drainage and intravenous administration of Naloxone were started immediately followed by keeping the systemic blood pressure more than 120 mmHg. However, paraplegia had never improved and been persistent with neurological deficit of the lower extremities. We herein report a complicated surgical case of an AAAD patient with paraplegia and review the complex clinical settings.

While several previous studies have indicated the link between periodontal disease (PD) and myocardial infarction (MI), the underlying mechanisms remain unclear. Autophagy, a cellular quality control process that is activated in several diseases, including heart failure, can be suppressed by Porphyromonas gingivalis (P.g.). However, it is uncertain whether autophagy impairment by periodontal pathogens stimulates the development of cardiac dysfunction after MI. Thus, this study aimed to investigate the relationship between PD and the development of MI while focusing on the role of autophagy. Neonatal rat cardiomyocytes (NRCMs) and MI model mice were inoculated with wild-type P.g. or gingipain-deficient P.g. to assess the effect of autophagy inhibition by P.g. Wild-type P.g.-inoculated NRCMs had lower cell viability than those inoculated with gingipain-deficient P.g. This study also revealed that gingipains can cleave vesicle-associated membrane protein 8 (VAMP8), a protein involved in lysosomal sensitive factor attachment protein receptors (SNAREs), at the 47th lysine residue, thereby inhibiting autophagy. Wild-type P.g.-inoculated MI model mice were more susceptible to cardiac rupture, with lower survival rates and autophagy activity than gingipain-deficient P.g.-inoculated MI model mice. After inoculating genetically modified MI model mice (VAMP8-K47A) with wild-type P.g., they exhibited significantly increased autophagy activation compared with the MI model mice inoculated with wild-type P.g., which suppressed cardiac rupture and enhanced overall survival rates. These findings suggest that gingipains, which are virulence factors of P.g., impair the infarcted myocardium by cleaving VAMP8 and disrupting autophagy. This study confirms the strong association between PD and MI and provides new insights into the potential role of autophagy in this relationship.
