The present paper reviews the extended follow up of all patients aged >/=70 who underwent isolated aortic valve replacement at our institution in the 1980s. Patients were identified from the surgical database and clinical information was gathered. Long-term follow up information was obtained from the patient, their family, or doctor. Ninety-three patients aged >/=70 years (median 73, range 70-80) comprised the study population. The indication for surgery was aortic stenosis in 68 patients (73%). Fifty-two patients (56%) received an allograft valve, 17 (18%) a bioprosthetic valve, and 24 (26%) a mechanical prosthesis. The median hospital stay was 12 days (range 0-105 days). Five surgical deaths occurred. Detailed follow up was obtained for the 71 patients who died later, and the 16 living patients (one patient lost). The median length of follow up was 6.8 years (range 0.1-18.9 years). Patients who received an allograft aortic valve had a significantly better long-term survival (median 10.6, 95% confidence intervals (CI) 8.1-13.8 years) compared to those receiving mechanical or bioprosthetic valves (median 6.5, 95% CI 4.7-11.9 years), P = 0.03. For the entire group, survival was similar to the age- and sex-matched population. Of the 16 patients alive at follow up (mean age 87, range 83-92), most were free of angina (12, 75%) and heart failure (10, 63%). The conclusion from the current study is that isolated aortic valve surgery in the elderly, particularly with an allograft valve, is associated with an excellent long-term outcome. A survival benefit was demonstrated comparing allograft aortic valve replacement to other valve types. 相似文献

Germ cell tumors (GCTs) are one of the more curable solid cancers in men. Approximately 8500 men are diagnosed with GCTs in the USA. The majority of patients survive due to the availability of effective treatment. Fewer than 400 men are estimated to die from their disease. Among those, there is a subset of patients with metastatic GCTs receiving chemotherapy who rapidly develop progressive respiratory failure and die during the early phase of their treatment course. In this review, we searched the available literature for reported cases and retrospective series of chemotherapy-associated acute respiratory distress syndrome in GCTs. We aim to determine whether a different approach from current treatment guidelines could be considered to prevent this catastrophic chemotherapy-related event. 相似文献

This report describes the case of a young woman who presented to an emergency department with severe abdominal pain and shock. The patient was found to have pericardial tamponade due to a massive pericardial effusion. On further evaluation, the etiology of this effusion was considered to be secondary to hypothyroidism with concominant acute viral pericarditis leading to a fulminant tamponade. The presentation, differential diagnosis, and management of pericardial effusion and tamponade secondary to hypothyroidism and viral pericarditis are discussed. The diagnosis of hypothyroidism in conjunction with acute viral pericarditis should be considered in patients presenting with unexplained pericardial effusion and tamponade. 相似文献

Chancroid, a sexually transmitted disease caused by Haemophilus ducreyi, is one of the most common genital ulcer diseases in developing countries. In the United States, while less common, the disease has been associated with outbreaks in inner cities, particularly among persons who engage in sex for drugs or money. Two outbreaks of chancroid were recently studied in the United States, one in New Orleans (from 1990 to 1992) and one in Jackson, Mississippi (from 1994 to 1995). By use of ribotyping, plasmid content, and antibiotic susceptibility, the chancroid cases in New Orleans were found to be due to a limited number of strains, consistent with a limited introduction of H. ducreyi into this community. The H. ducreyi isolates from New Orleans and Jackson had different ribotype patterns, suggesting that the two outbreaks were probably not linked. 相似文献

AIMS: To determine the prevalence of cardiac allograft vasculopathy in heart transplant recipients at Green Lane Hospital and to examine potential risk factors for vasculopathy. METHODS: We retrospectively reviewed the coronary angiograms of all cardiac transplant recipients. Angiography was usually performed one, two and five years after operation. The diagnosis of allograft vasculopathy was made if there was any evidence of coronary artery disease. Patients' medical records were reviewed for potential risk factors. RESULTS: Ninety-one patients underwent cardiac transplantation between December 1987 and March 1998. One year survival was 87%. Angiographic evidence of coronary disease was present in 30 patients and in three patients coronary lesions were first identified at post mortem. Vasculopathy was present in 25%, 35% and 61% of patients at one two and five years following transplant. Donor-acquired lesions could not be excluded as few patients had immediate postoperative angiograms for comparison. Five late deaths have been due to vasculopathy. Recipient age, race, donor age and ischaemic time were similar for those with and without vasculopathy. Frequency or severity of acute rejection episodes, cytomegalovirus infection, lipid profiles, diabetes and hypertension were not significantly different in patients with vasculopathy. CONCLUSION: Cardiac allograft vasculopathy is a common finding after heart transplantation. No definite risk factors were identified in this patient group. 相似文献

Summary A total of 23 patients with advanced malignancies received escalating doses of epirubicin (100–120 mg/m2) i.v. at 3-week intervals; 15 had received previous chemotherapy. In all, 46 courses of chemotherapy were given. Mucositis (grade II or III) occurred in 47% of courses at 120 mg/m2, but in only 15% of courses at 115 mg/m2. Myelotoxicity was manifest as leucopenia, with a median white blood count nadir of 1.9 (range, 0.8–7.0)×109/l. Nausea and vomiting were generally well controlled by prophylactic antiemetic therapy. Alopecia was WHO grade 0 in 2 patients, grade I in 1, grade II in 5 and grade III in 14. No renal or hepatic toxicity was noted, and there were no episodes of congestive cardiac failure. One fatal coronary thrombosis (proven at post-mortem examination) occurred 48 h after a dose of 115 mg/m2. Four patients developed thrombophlebitis at the injection site that was not dose-related; it occurred at doses between 100 and 120 mg/m2. Two patients who had been given chemotherapy in the past had complete responses (one penile carcinoma, one gastric carcinoma). Six patients had partial responses, including two with breast cancer, one with gastric cancer and three with sarcoma. Intermediate-dose epirubicin was well tolerated up to 120 mg/m2, when mucositis became a significant clinical problem. Preliminary data suggest promising activity in gastric cancer, breast cancer and a variety of sarcomas. 相似文献

In a series of 34 lung transplant patients, donor lung dysfunction occurred on 7 occasions. One patient underwent retransplantation and the remaining 6 were treated conservatively. Survival was 100% in the donor lung dysfunction group. Percent predicted forced expiratory volume in 1 second, carbon monoxide diffusion, room air oxygen tension, and distance walked in 6 minutes were all lower (p less than 0.05) at 1 month after transplantation in those patients with donor lung dysfunction as compared with those without. These differences were not significant at 3 months after transplantation. We conclude that donor lung dysfunction can usually be managed conservatively with satisfactory results. Longer follow-up of this group of patients will be necessary to determine the long-term consequences of early graft injury. 相似文献
