Limited vertical skin incision for median sternotomy. 总被引:4,自引:0,他引:4
S Tatebe S Eguchi H Miyamura S Nakazawa H Watanabe M Sugawara J Hayashi K Date S Nakagawa 《The Annals of thoracic surgery》1992,54(4):787-788
The cosmetic deformity of the vertical skin incision for median sternotomy was decreased by using a mechanical traction system to increase exposure at the superior margin of a shorter wound. The limited vertical skin incision did not impede technical surgical maneuvers and produced a scar that was more acceptable than submammary incision or right anterior thoracotomy. The limited skin incision is especially useful in young women with congenital heart disease. 相似文献

A 2-year-old boy presented with an accessory scrotum associated with penoscrotal transposition and a perineal lipoma. He also had a retrocerebellar arachnoid cyst. The accessory scrotum was resected with concurrent scrotoplasty. The retrocerebellar arachnoid cyst was seen on a subsequent brain computed tomography scan and was left untreated because there was no evidence that the volume was increasing. 相似文献

OBJECTIVE: To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT). STUDY DESIGN AND SETTING: Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods. RESULTS: The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated. CONCLUSION: Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement. SIGNIFICANCE: This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy. 相似文献

The transplacental passage of single intravenous doses of aztreonam (AZT), 1 g or 2 g, was examined in 7 sheep and 14 women in late pregnancy, respectively and the obtained data were analyzed by a two-compartment model. The obtained results were summarized as follows. After single 2 g intravenous doses were given to pregnant sheep, the mean peak level of AZT in maternal blood was 83.79 micrograms/ml and the half-life of the beta-phase was 1.525 hours. After single 1 g intravenous doses were administered to pregnant women, the mean peak level of AZT in blood was 102.62 micrograms/ml and the half-life of beta-phase was 2.128 hours. The peak levels in umbilical venous blood and amniotic fluid were 14.43 micrograms/ml and 11.86 micrograms/ml, respectively. 相似文献

Passing of the AIDS Prevention Bill, which demands the notification of human immunodeficiency virus (HIV) carriers, seems imminent in Japan. Its effect on people's willingness to be tested for the HIV antibody was assessed among heterosexual subjects (students, office workers) and groups at high risk of the acquired immunodeficiency syndrome (AIDS) (prostitutes, homosexual males) by means of a questionnaire. More than 70% of the 811 students and the 509 workers replied that, if notification became mandatory, they would agree to be tested but 10% of the males and 17% of the females in these two groups would prefer testing at institutes not complying with the clause; all 198 prostitutes said they would be prepared to undergo testing but 35% of them would prefer to go to non-complying clinics; 45% (410) of the 902 homosexual males replied that they would refuse testing, and 65% of those who agreed to be tested (492) would prefer to go to non-complying clinics.... 相似文献

To investigate initial changes in the olfactory epithelium, vincristine sulphate (VCR) was administered intravenously once to male BALB/c mice on day 1 in comparison with unilateral bulbectomy (UBT). The light and electron microscopy of the olfactory epithelium, nerve and/or bulb with BrdU-morphometry was performed sequentially. Further, whole-body radioluminography was conducted at 1 and 24 hours postdose. Apoptosis and an increased number of mitotic cells with a tendency toward decreasing BrdU-positive olfactory epithelial cell counts were observed in olfactory epithelial cells at 6 hours postdose of VCR and became more pronounced at 24 hours postdose. These changes disappeared on days 4 or 15, but minimal axonal degeneration was seen in the olfactory nerve from day 4 onward. Semiquantitative measurement of VCR levels in the ethmoturbinals elicited high drug retention even 24 hours after administration. In contrast, UBT showed no effect on mitosis and BrdU-positive cell counts at 6 hours postdose, but severe lesions in the olfactory epithelium and nerve were seen on days 2, 4, and/or 15. The above results suggest that the initial event of VCR-induced apoptosis in the mouse olfactory epithelium would be mitotic arrest with high drug retention, unlike that evoked by UBT. 相似文献
