The body composition of 36 professional Sumo wrestlers and 39 collegiate male students were assessed densitometrically. The means of body weight, BMI and %fat for Sumo wrestlers were 117.1 kg, 36.5 and 26.2%, extraordinarily large compared with untrained men (p < 0.001). Results of the analysis of variance of divisions of Sumo wrestlers revealed significant differences in body weight, fat-free mass, fat mass, BMI, fat-free mass index (FFM/height2) and fat mass index (FM/height2). For the visual expression of the hierarchical differences of body composition, fat mass index and fat-free mass index of the wrestlers in various leagues were plotted on a body composition chart. Wrestlers in the Sekitori division had significantly larger fat-free mass index scores in comparison with wrestlers from the lower divisions who share a common area of the chart. The cut-off point of fat-free mass index which divided Sekitori wrestlers from other wrestlers is approximately 30 and this value may be one of the anthropometrical indications of whether or not a Sumo wrestler is destined to be successful. 相似文献
The differentiation of complete mole (CM), an aberrant androgenetic conceptus, from partial mole (PM) and hydropic abortion (HA) in early gestations is very important for patient management. In this study, 10 diploid voluntary artificial abortions (ABs), 20 diploid HAs, 20 triploid PMs, and 44 diploid CMs (including 4 persistent diseases), all of which were in the first trimester, were evaluated by immunohistochemistry of formalin-fixed tissues using a monoclonal antibody against p57(KIP2) protein (p57), a putative paternally imprinted inhibitor gene. DNA ploidy in all cases was analyzed by flow cytometry. In all ABs, nuclear p57 was strongly expressed in cytotrophoblasts, intermediate trophoblasts, villous stromal cells, and decidual stromal cells but was absent in syncytiotrophoblast. In diploid CMs, p57 expression in cytotrophoblasts and villous stromal cells was either absent (37 cases) or very low (7 cases). Villous intermediate trophoblasts stained for p57 in 12 cases of CM. On the other hand, 16 HAs and 19 PMs showed p57 levels comparable to those observed in ABs. Decidual stromal cells provided a reliable internal control in all cases. These findings support the hypothesis that misexpression of p57 is involved in the abnormal development of androgenetic CMs. This immunohistochemical analysis is a useful tool for the differential diagnosis of CMs. 相似文献
BACKGROUND: Although there have been numerous reports in personality of mood disorders, there have been few reports in regard with personality of winter seasonal affective disorder (SAD). Furthermore, no reports have been published concerning summer SAD personality characteristics. Thus, this study was conducted to assess the personality of winter and summer SAD using Tri-dimensional Personality Questionnaire (TPQ) that have been used in a variety of mental disorders. METHODS: A total of 6135 Japanese were evaluated with TPQ, the Seasonal Pattern Assessment Questionnaire (SPAQ) and the Self-rating Depression Scale (SDS). Winter, summer and non-SAD groups were classified by SPAQ. We compared the difference of personality trait among these three groups in consideration of gender, age and SDS score influence. RESULTS: Winter SAD demonstrated higher "Novelty Seeking" and "Harm Avoidance"; summer SAD showed higher "Harm Avoidance" than the non-SAD group. "Harm Avoidance" in both SAD groups was re-analyzed using SDS score as a covariate, and "Novelty Seeking" in winter SAD using age as a covariate. As a result, the significance of high "Novelty Seeking" and high "Harm Avoidance" in winter SAD was excluded. However, "Harm Avoidance" remained the significant difference between summer and non-SAD. LIMITATION: SAD was diagnosed only by SPAQ and not by interview. The state-dependency of "Harm Avoidance" was not confirmed in identical patients over lapse of time. CONCLUSION: Patients with winter SAD have high "Harm Avoidance" dependent on the depressive state that is in accordance with non-seasonal depression. Patients with summer SAD have high "Harm Avoidance" possibly independent from the depressive state. 相似文献
In the anesthetic management of five patients undergoing excision of pheochromocytoma, adenosine triphosphate (ATP) was used for the purpose of regulating systemic arterial pressure during the period of tumor manipulation. ATP was administered at doses of 0.05–0.4mg/kg/min. Systemic arterial pressure showed a significant decrease from 162 ± 17/103 ± 11mmHg before manipulation to 136 ± 21/81 ± 10mmHg during the manipulation period. The plasma catecholamine levels showed significant increases in this period. Immediately after excision, the systemic arterial pressure was maintained at normal levels (118 ± 13/75 ± 16mmHg) by fluid replacement and discontinuation of ATP administration, subsequently becoming 129 ± 19/79 ± 16mmHg. The heart rate was very stable and tachycardia did not ocurr during the manipulation period. Only one arrhythmic episode ocurred in one patient. The systemic vascular resistance index was significantly lower during the manipulation period than before it. It was therefore considered that ATP was useful as an agent for controlling arterial pressue during the anesthesia for pheochromocytoma.(Murata K, Sodeyama O, Ikeda K et al.: Prevention of hypertensive crisis with ATP during anesthesia for pheochromocytoma.

In the course of celiac plexus alcohol block, facial flushing, palpitations, and hypotension are occasionally incurred in some patients. We hypothesized that the phenomenon represents acetaldehyde syndrome, not response to increased blood levels of ethanol as might be supposed. In order to prove our hypothesis, we selected five patients scheduled to undergo celiac plexus alcohol block, and, with their consent, we measured blood concentration of ethanol and acetaldehyde before and for 6 hr after the block. We also determined the phenotypes of aldehyde dehydrogenase (ALDH) in their hair roots. We found that "flushers" are found exclusively among subjects without ALDH I, and that their blood levels of acetaldehyde were significantly higher than those of "non-flushers" within 10 min after the block. The flushers also gave histories of facial flushing after ingestion of small amounts of ethanol. On the basis of such histories one can anticipate whether acetaldehyde syndrome is likely or unlikely to accompany the block. 相似文献
Intravesical bacillus Calmette–Guérin (BCG) is the standard of care for bladder carcinoma in situ (CIS). The response to BCG therapy against CIS is generally assessed by random bladder biopsy (RBB). In this study, we examined the necessity of routine RBB after BCG therapy.
Methods
We retrospectively identified 102 patients who were initially diagnosed with CIS with or without papillary tumor and received subsequent 6–8-week BCG therapy. Thereafter, all patients underwent voiding cytology analysis, cystoscopy, and RBB to evaluate the effects of BCG therapy. We evaluated the association between clinical parameters (voiding cytology and cystoscopy findings) and the final pathological results by RBB specimens.
Results
According to the pathological results of RBB, 30 (29%) patients had BCG-unresponsive disease (remaining urothelial carcinoma was confirmed pathologically) and 20 were diagnosed with CIS. Positive/suspicious voiding cytology and positive cystoscopy findings were well observed in patients who had BCG-unresponsive disease compared with their counterparts (p?=?0.116, and p?<?0.001, respectively). The sensitivity (Sen.), specificity (Spe.), positive predictive value (PPV), and negative predictive value (NPV) of voiding cytology were 50%, 68%, 39%, and 77%, respectively. The values for cystoscopy findings were as follows: Sen.: 87%, Spe.: 57%, PPV: 46%, and NPV: 91%. The values for their combination (having either of them) were as follows: Sen.: 100%, Spe.: 44%, PPV: 43%, and NPV: 100%.
Conclusion
RBB after BCG therapy for patients with negative voiding cytology and negative cystoscopy may be omitted because their risk of BCG-unresponsive disease is significantly low (NPV: 100%).
