The effects of transdermal nitrate (TN) (Transiderm-Nitro TTS, Geigy Pharmaceuticals, one 10 cm2 patch daily) and oral isosorbide dinitrate (ISDN) (Sorbitrate, Stuart Pharmaceuticals, 10 mg three times daily) were compared in a group of 20 patients with chronic stable angina pectoris. Treadmill exercise duration was prolonged from a median time of 365 s to 428 s after ISDN (P less than 0.05), but was unchanged after TN. The difference between the active treatments was not significant. Weekly consumption of glyceryl trinitrate (GTN) increased during treatment with TN from a median value of 5.5 to 6.3 (P less than 0.05). A decrease was observed after ISDN (7.8 to 3.9, P = NS), and the difference between the drugs was significant (P less than 0.01). Systolic arterial pressure was significantly lower during the ISDN than during the TN treatment period in both the supine (135 +/- 5 vs 128 +/- 5 mm Hg; P less than 0.05) and standing positions (134 +/- 5 vs 122 +/- 5 mm Hg; P less than 0.05). No change in weekly attack rate, the degree of ST depression at angina on treadmill testing, or the number of episodes of ST depression recorded during a 24 h period by Holter monitoring was observed after either drug. In this study, an antianginal effect was demonstrated for ISDN but not for TN. It is suggested that the dose of TN may have been inadequate to demonstrate such an effect, and further studies using a higher dose schedule will be required. 相似文献

We report two cases of aortic dissection during coronary angioplasty with a disparate evolution that was due to the different location of the entry port of the dissection. Aortic dissection occurring during coronary angioplasty may be self-limiting, but it may also be life-threatening and may call for urgent surgical repair. 相似文献

Coronary pacing using as unipolar negative electrode a guidewire placed in a coronary branch was tested in 349 sites of 300 consecutive patients undergoing coronary angioplasty. It was possible for 339 sites (97%). The threshold currents ranged from 1 to 15 (mean +/- standard deviation 3.4 +/- 2.4) mA. Side effects were seen in 13 patients (4%): 6 (2%) had transient coronary spasm, 4 (1%) had diaphragmatic stimulation, and 3 (1%) had stinging pain at the skin electrode. Of the 10 cases with pacing failure, left ventricular pacing was successfully tested in 5 by introducing the coronary wire or another wire into the left ventricle. It yielded a threshold of 2-8 (3.2 +/- 2.7) mA. Therapeutic pacing for significant bradycardia was required in 7 patients (2%). It was successful in all. Coronary or left ventricular pacing appears to be a simple and reliable temporary measure. When there is no wire in the coronary artery or for diagnostic catheterization, left ventricular pacing can be done using the same setup and any type of guidewire. 相似文献

Purpose: Successful replacement of posterior teeth using contemporary prosthodontic techniques in esthetically demanding cases relies upon visual replication of the natural posterior dentition and surrounding gingival architecture. There is currently little in the way of guidance for creating ideal or acceptable gingival relationships for posterior teeth. Materials and Methods: A cross‐sectional study was conducted comparing perceptions of four groups of individuals to six digitally manipulated images with various posterior teeth gingival margin position configurations. A total of 120 volunteers aged 12 years to 80 years, comprising 30 patients diagnosed with hypodontia, 30 patients diagnosed with periodontal disease, 30 patients without either condition, and 30 qualified dentists were recruited from the Eastman Dental Institute & Hospital, London. A ranked order of preference for each set was obtained, and this was repeated after a minimum time interval of 10 minutes. Results: Posterior gingival margin configurations from 0 mm to 2 mm (measured at the first premolar) were deemed most esthetic by the majority of the patient groups; dentists had a strong preference for the 1 mm configuration. Dentists appeared to be more perceptive to the alterations in gingival positions. Conclusions: Posterior gingival margin configurations where the first premolar margins were 1 mm lower than the canine margins were deemed the most esthetically pleasing; however, it is likely that a range of acceptability of 1 mm deviations from this ideal exists. 相似文献

Intraperitoneal chemohyperthermia (IPCH) with Cytoreductive surgery (CS) has been used in Centre Hospitalier et Universitaire Lyon Sud (CHLS) since 1989. Up to 2005· 420 patients were involved in different phase II studies for peritoneal carcinomatosis (PC) from colorectal· gastric or ovarian origin· as well as for pseudomyxoma peritonei and peritoneal mesothelioma. Encouraging results were achieved in case of optimal PC cytoreduction. The CHLS experience· as well as the Dutch randomized trial and the international registration· underline the advantage of such an aggressive combined therapy for selected patients in experienced multidisciplinary centers. 相似文献
