Hypertrophic cardiomyopathy with progression from apical hypertrophy to asymmetrical septal hypertrophy: a case report

A 41-year-old man was referred to our hospital for further examination because of abnormal electrocardiography findings at a health-check examination. Transthoracic echocardiography showed left ventricular hypertrophy confined to the most distal portion of the left ventricle, which is a typical feature of apical hypertrophic cardiomyopathy. Ten years later, he was again admitted for the evaluation of chest pain. Echocardiography showed asymmetrical septal hypertrophy in addition to apical hypertrophy. These findings demonstrate morphologic evolution in hypertrophic cardiomyopathy from apical hypertrophy to asymmetrical septal hypertrophy.     

Effects of alendronate on bone mineral density and bone metabolic markers in postmenopausal asthmatic women treated with inhaled corticosteroids

We have recently shown that long-term use of inhaled corticosteroids decreases bone mineral density (BMD) of the lumbar spine in postmenopausal asthmatic women. The present study aimed to evaluate the efficacy of alendronate in comparison with that of alfacalcidol (1-alpha-hydroxyvitamin D(3)) for the treatment of BMD reduction in postmenopausal asthmatic patients who had inhaled corticosteroid therapy without regular use of systemic corticosteroids. Twenty-eight postmenopausal asthmatic patients with BMD T score of -1.0 or less were randomized to receive alendronate (5 mg/d) or alfacalcidol (1 microg/d). Bone mineral density was determined at baseline and 12 months after the treatment, and biochemical markers of bone metabolism were measured at baseline and after 6 and 12 months of treatment. The mean (+/-SD) BMD values at the lumbar spine, the total hip, and the Ward's triangle significantly increased by 4.9 +/- 4.5% (P = .0005), 2.4 +/- 2.2% (P = .0005), and 3.6 +/- 5.2% (P = .02) at 12 months in the alendronate group, whereas the corresponding values did not significantly change in the alfacalcidol group. In the alendronate group, urinary N-telopeptide (NTx), serum osteocalcin, and serum alkaline phosphatase concentrations significantly decreased, and serum intact parathyroid (PTH) level significantly increased, from baseline at both 6 and 12 months. In the alfacalcidol group, urinary NTx showed modest but significant decrease, although the extent of the change was smaller than that in the alendronate group. We concluded that alendronate was effective to improve reduced BMD in postmenopausal asthmatic patients on inhaled corticosteroid therapy through the mechanism of inhibiting bone resorption.     

Action of aspirin on whole blood-aggregation evaluated by the screen filtration pressure method.

BACKGROUND: There are few monitoring systems widely used in clinical practice for evaluating the effectiveness of aspirin therapy, so in the present study aspirin's antiplatelet effects we investigated with a whole blood aggregometer using a screen filtration pressure (SFP) method. METHODS AND RESULTS: Thirty-five healthy male volunteers took 100 mg/day aspirin for 14 days. Whole-blood aggregation was analyzed at baseline and on days 7 and 14, using collagen and adenosine diphosphate as the stimuli, and compared with the platelet-rich plasma (PRP) aggregation measured by optical aggregometer. The platelet-aggregation threshold index (PATI) for both methods, which was defined as the putative agonist-concentration giving half-maximal aggregation, and the PRP-maximal aggregation rate were analyzed. The maximal aggregation rate induced by 1.6 mg/L collagen decreased from 85.5% (80.8-92.8) [median (interquartile range)] at baseline to 51.5% (39-63.8) on day 14 (p<0.0001). The PRP-PATI and whole-blood PATI for collagen increased from 0.32 (0.28-0.70) to 1.82 mg/L (1.25-2.89) (p<0.0001) and from 0.28 (0.22-0.3) to 1.06 mg/L (1.01-1.29) (p<0.0001) respectively. CONCLUSIONS: The whole-blood PATI and PRP-PATI for collagen, as well as the maximal PRP aggregation rate, clearly distinguish platelet aggregability before and after aspirin intake. However, whole-blood analysis by the SFP-method is easier to perform, and is a promising method of monitoring aspirin's effects.     

Clinical factors that impair health-related quality of life in ulcerative colitis patients vary with the disease duration

BACKGROUND AND AIM: The health-related quality of life (HRQOL) of patients with ulcerative colitis (UC) can be impaired because of the chronic symptoms. Although UC patients suffer from such symptoms over the long term, there have been few reports on the changes of HRQOL with disease duration. The aim of this study was to clarify these changes. METHODS: The HRQOL of 331 Japanese UC patients was examined using the validated Japanese version of the Inflammatory Bowel Disease Questionnaire (J-IBDQ). HRQOL and factors affecting HRQOL identified using multiple linear regression analysis were stratified by disease duration. RESULTS: Of the 15 clinical factors examined, the clinical activity index score was the strongest determinant (P<0.0001) of all the scores of IBDQ regardless of disease duration. HRQOL did not differ significantly among patients with different disease durations. The factors, however, that affected HRQOL varied according to disease duration. In patients with disease duration of less than 5 years, the clinical activity index score was the predominant factor affecting HRQOL. Being 'on sick leave or hospitalized' was a significant factor impairing HRQOL in patients with disease duration of 5-9 years. Moreover, complications due to corticosteroids significantly impaired all of the IBDQ scores in patients with disease duration of 10 years or more. CONCLUSION: Factors that affected the HRQOL of UC patients varied according to the patients' disease duration. Our findings should assist in the development of a long-term strategy for the treatment of UC patients.
