Ambulatory Blood Pressure Monitoring in Diabetes and Obesity—A Review
Diabetes mellitus and obesity are both related to the risk of cardiovascular disease and sudden death. In hypertensive guidelines, diabetes and obesity, especially abdominal obesity, are regarded as high-risk factors. Ambulatory blood pressure monitoring (ABPM) is an established method for the management of hypertension. However, ABPM is not a standard tool for the management of hypertension in diabetes and obesity. In this paper, recent data on the use of ABPM in diabetes and obesity will be discussed. In patients with diabetes, the ambulatory BP level has been shown to be better than clinic BP in predicting cardiovascular events. A riser pattern has been associated with increased risk of cardiovascular disease. White-coat hypertension and masked hypertension in diabetics constitute a moderate risk. A nondipping pattern is very common in obese hypertensive patients. In this paper, we will summarize the findings on the use of ABPM in patients with diabetes and obesity

A Case of Syncope Induced in the Supine Position
We experienced a reproducible supine syncope followed by upper abdominal pain. A 66-year-old man was transferred to our hospital after an episode of syncope during sleep. He had a history of acute pancreatitis, diabetes, hypertension, and dyslipidemia, but no history of presyncopal attack. One night, his wife noticed he was snoring abnormally in bed, and he did not respond to her voice until after she tried many times to wake him. The same attack was reproduced three times in the same situation. One of the attacks was recorded under a continuous ECG and radial tonometry. In this case, a presyncopal attack and a sense of ill-feeling were provoked by the patient lying in a prolonged supine position. He was eventually diagnosed as metastatic liver tumor 5 months after the first attack. Because few cases of syncopal attack have been reported in the supine position, its underlying mechanisms deserve consideration
An intrathoracic scapular prolapse with hemorrhagic shock after a thoracotomy
We herein present a case in which an emergency operation was performed for an intrathoracic hemorrhage resulting from a scapular prolapse after a thoracotomy, a rare complication of this procedure. A 59-year-old man had undergone a right upper lobectomy with an extended resection of the posterior chest wall including the second to fourth ribs due to a direct invasion by a lung cancer. On postoperative day 80, we performed an emergency operation as the patient had gone into shock due to an intrathoracic hemorrhage with a right scapular prolapse. The scapula protruded through the enlarged fourth intercostal space. The prolapsed scapula was reduced and the defect in the chest wall was covered with Marlex mesh.ArticleINTERACTIVE CARDIOVASCULAR AND THORACIC SURGERY. 12(2):326-327 (2011)journal articl
Coexistence of a pulmonary adenocarcinoma with a focal organizing pneumonia
We report a case of a pulmonary adenocarcinoma in coexistence with an organizing pneumonia. A 73-year-old male presented with an abnormal shadow on a chest X-ray. The pathological diagnosis, made via a partial resection, was a focal organizing pneumonia with reactive proliferation of the bronchial epithelium. Three years later, two tumors adjacent to the staple line were revealed by computed tomography. A left lower lobectomy was performed and both tumors were diagnosed as an adenocarcinoma. Because the histological findings for the atypical epithelial areas of the previous tumor were similar to the two new lesions in this patient, we regarded these tumors as a marginal recurrence.ArticleINTERACTIVE CARDIOVASCULAR AND THORACIC SURGERY. 13(4):444-446 (2011)journal articl
General Projective Connections and Finsler Metric
This paper is the continuation of the paper formerly written by one of the authors (Ichijyo). In the former paper, the general projective connections on the tangent bundle over a C^∞-manifold were discussed. But, in that case, it was necessary to choose canonical parameters independently. In this paper, we first consider a vector bundle having R^, the real number space of (n+1)-dimensions, as the standard fibre and a subgroup of GL(n+1; R) as the structural group. This vector bundle was introduced by T. Otsuki for studying his restricted projective connection and was named a projective vector bundle. Now, our intention is on the generalization of the former case to the projective vector bundle. In §§1 and 2, we define the projective vector bundle and the general projective connection on it, and discuss some properties of them. Then, a projectively invariant distribution p is defined. The integrability condition for p is discussed in §3. §4 is devoted to the study of the holonomy group of the general projective connection, especially the case in which the holonomy group leaves a certain hypercone invariant is studied. In the last section we try to extend some known results on holonomy groups to the case in which the base manifold of the projective vector bundle is assumed to have a Finsler metric. As for the references, we wish to refer the former paper
Successful lung lobectomy for a lung cancer following thoracic endovascular aortic repair for a thoracic aortic aneurysm: report of a case
Lung cancer and a thoracic aortic aneurysm were detected simultaneously in a 79-year-old male patient with diabetes. The aneurysm was first treated by thoracic endovascular aortic repair. A right lower lobectomy was subsequently performed after the blood flow of the bronchial and intercostal arteries was confirmed by computed tomographic angiography. The bronchial stump was covered with an intercostal muscle flap. The patient's postoperative course was uneventful. Thoracic endovascular aortic repair is a useful and less invasive treatment for such cases, but a blood flow evaluation of the aortic branches should be done following this procedure before a lung resection is considered.ArticleSURGERY TODAY. 44(5):940-943 (2014)journal articl
Cardiac sarcoidosis, the complete atrioventricular block of which was completely recovered by intravenous steroid pulse therapy
AbstractAtrioventricular block (AVB) in individuals with cardiac sarcoidosis (CS) is one of the major complications caused by inflammation of the conducting system of the heart, as a sign of worse prognosis. We report the case of a 53-year-old Japanese woman whose electrocardiogram showed complete AVB by the clinical diagnosis of CS. We administered intravenous methylpredonisolone (1g/day) for 3 days. On the second day of steroid pulse therapy, the complete AVB improved to sinus rhythm of 1st degree AVB and complete right bundle branch block. Normal sinus rhythm was then observed after oral steroid therapy. These results suggest that in cases of complete AVB, steroid pulse therapy with a strong anti-inflammatory effect may be recommended first.<Learning objective: This case illustrates a typical case of CS with complete AVB, but the cardiac contraction was normal. In this setting, steroid pulse therapy may be effective when (1) the active inflammation of the conduction system can be suppressed by steroid pulse therapy; (2) the time to start steroid therapy is short enough to recover.

What is the optimal interval between successive home blood pressure readings using an automated oscillometric device?
Objectives: To clarify whether a shorter interval between three successive home blood pressure (HBP) readings (10 s vs. 1 min) taken twice a day gives a better prediction of the average 24-h BP and better patient compliance.
Design: We enrolled 56 patients from a hypertension clinic (mean age: 60 ± 14 years; 54% female patients). The study consisted of three clinic visits, with two 4-week periods of self-monitoring of HBP between them, and a 24-h ambulatory BP monitoring at the second visit. Using a crossover design, with order randomized, the oscillometric HBP device (HEM-5001) could be programmed to take three consecutive readings at either 10-s or 1-min intervals, each of which was done for 4 weeks. Patients were asked to measure three HBP readings in the morning and evening. All the readings were stored in the memory of the monitors.
Results: The analyses were performed using the second–third HBP readings. The average systolic BP/diastolic BP for the 10-s and 1-min intervals at home were 136.1 ± 15.8/77.5 ± 9.5 and 133.2 ± 15.5/76.9 ± 9.3 mmHg (P = 0.001/0.19 for the differences in systolic BP and diastolic BP), respectively. The 1-min BP readings were significantly closer to the average of awake ambulatory BP (131 ± 14/79 ± 10 mmHg) than the 10-s interval readings. There was no significant difference in patients' compliance in taking adequate numbers of readings at the different time intervals.
Conclusion: The 1-min interval between HBP readings gave a closer agreement with the daytime average BP than the 10-s interval

Nocturnal nondipping of heart rate predicts cardiovascular events in hypertensive patients
Objective: It has not been established whether nocturnal nondipping of heart rate (HR) predicts future cardiovascular disease (CVD). We performed this study to test the hypothesis that nocturnal nondipping of HR predicts the risk of incident CVD independent of nocturnal blood pressure dipping pattern.
Methods: Ambulatory blood pressure monitoring was performed in 457 uncomplicated patients, who were being treated or evaluated for hypertension. They were followed for an average of 72 ± 26 months. Nondipping HR was defined as a night/day HR ratio greater than 0.90. We chose two outcomes for this analysis: CVD events (defined as stroke, myocardial infarction, or sudden cardiac death) and all-cause mortality. Cox regression analyses (stepwise method) were used to estimate hazard ratios and their 95% confidence interval after adjusting for covariates.
Results: In univariate analysis, increased sleep HR and nondipping of HR were associated with increased risk of CVD and all-cause mortality, but awake HR was not. In multivariable analyses, HR nondipping status significantly predicted an increased risk of CVD events (hazard ratio, 2.37; 95% confidence interval, 1.22–4.62; P = 0.01), but not for all-cause mortality. Increased 24-h HR was significantly associated with increased risk of all-cause mortality (hazard ratio, 1.67; 95% confidence interval, 1.11–2.51; P = 0.01).
Conclusion: The risk of future CVD was shown to be 2.4 times higher in those whose HR does not exhibit the typical nocturnal decline. The relationship was independent of nondipping of SBP and was not dependent on diabetes status or blood pressure level
