PURPOSE: The aim of this retrospective study was to compare the outcome of in vitro fertilization and embryo transfer in women with endometriosis and a control group with tubal-factor infertility. METHODS: Forty-eight patients with endometriosis underwent 65 cycles of in vitro fertilization and embryo transfer at Huddinge University Hospital. The matched control group with tubal-factor infertility consisted of 98 cycles in 98 patients. These groups were retrospectively analyzed regarding stimulation, fertilization, embryo development, implantation, and pregnancy outcome. RESULTS: The fertilization rate was significantly lower in women with endometriosis, but the cleavage, implantation, and pregnancy rates did not differ. CONCLUSIONS: Our results show that women with endometriosis have a lower fertilization rate compared with women with tubal-factor infertility. However, once the oocyte is fertilized, it seems that the preembryo has a normal chance of implantation, leading to similar pregnancy rates.  相似文献

PURPOSE: This retrospective study reports the long-term surgical outcome of patients with medically refractory epilepsy and vascular malformations who were treated with lesionectomy. A detailed analysis of surgical failures had been performed in an attempt to define predictors of surgical success and failure. METHODS: Fifteen patients with medically intractable epilepsy and angiographically occult vascular malformations (AOVMs) were treated surgically with lesionectomy at Duke University Medical Center. Lesionectomy consisted of removal of the AOVM and surrounding hemosiderin-stained brain only, without the use of electrocorticography (ECoG) to guide resection. RESULTS: Eleven (73%) patients are seizure free after lesionectomy. Three showed no significant improvement, and one patient died, presumably after a seizure. Age of onset, duration of seizures, age at resection, and gender did not affect outcome. All patients with neocortical AOVMs in whom EEG findings correlated with the site of the lesion were seizure free after lesional resection. Treatment failures were associated with the presence of multiple intracranial lesions, poorly localized or diffuse EEG findings, discordant positron emission tomography (PET) imaging, or with a lesion in close proximity to the limbic system. CONCLUSIONS: Lesionectomy, with removal of surrounding hemosiderin-stained brain, can be considered the procedure of choice in carefully selected patients with epilepsy with occult vascular malformations.  相似文献

INTRODUCTION: The exercise stress test shows limited diagnostic accuracy for the detection of coronary artery disease in hypertensive patients. Echocardiography with dobutamine is a useful tool in the assessment of coronary artery disease. PURPOSE: Our purpose has been to compare dobutamine stress echocardiography and exercise stress test for diagnosing coronary disease in hypertensive patients. MATERIAL AND METHODS: Dobutamine stress echocardiography (administered up to 40 micrograms/kg/min, and atropine when necessary), exercise stress test and coronary arteriography were performed on 74 hypertensive patients with chest pain and no previous history of coronary artery disease. RESULTS: Forty-eight (65%) patients underwent a diagnostic exercise stress test and 66 (89%) a diagnostic dobutamine stress echocardiography. Coronary artery disease (> or = 70% stenosis in, at least, one major vessel) was demonstrated in 28 (58%) patients who underwent a diagnostic exercise stress test, and in 39 (59%) patients who completed a dobutamine stress echocardiography. Sensitivity for exercise stress test was 82%, and 79% for dobutamine stress echocardiography (p = NS). Specificity was higher for dobutamine stress echocardiography (100% vs 60%; p < 0.005). CONCLUSIONS: Dobutamine stress echocardiography has high sensitivity and specificity for the detection of coronary artery disease in hypertensive patients. Dobutamine stress echocardiography has higher feasibility and specificity than exercise stress test in this group of patients.  相似文献

BACKGROUND: Immunosuppressive treatment with cyclosporin A (CsA) improves the survival of renal allografts, but is associated with renal vasoconstriction and hypertension. Previous reports suggest that the calcium-channel blockers nifedipine and amlodipine may improve graft function in CsA-treated patients. We have compared the effects of amlodipine (5-10 mg once daily) and nifedipine retard (10-40 mg twice daily) on renal function and blood pressure in renal transplant recipients treated with CsA. METHODS: This was a multicentre, two-way, crossover study in 27 evaluable hypertensive patients with renal insufficiency following renal transplantation, who were maintained on a stable dose of CsA. Patients received either amlodipine (5-10 mg once daily) or nifedipine retard (10-40 mg twice daily) for 8 weeks, and were then crossed over to the other treatment for a further 8 weeks. RESULTS: Trends were seen during amlodipine treatment towards larger improvements, in serum creatinine (by 8% of baseline on amlodipine vs 4% on nifedipine), lithium clearance (13% vs 2%), and glomerular filtration rate 11% vs 7%). Effective renal plasma flow was increased by 11% of baseline on nifedipine vs 9% on amlodipine. There were no significant differences between treatments. Amlodipine and nifedipine lowered systolic blood pressure to a similar extent (21 mmHg vs 15 mmHg respectively, P=0.25), but amlodipine was more effective than nifedipine in lowering diastolic blood pressure (13 mmHg vs 8 mmHg, P=0.006). Both treatments were well tolerated. CONCLUSION: Once-daily amlodipine is at least as effective as twice-daily nifedipine retard in controlling blood pressure and does not adversely affect graft function in hypertensive renal allograft recipients.  相似文献

Breast cancer is the second commonest primary tumour responsible for gastrointestinal metastases after malignant melanoma. The real incidence of gastrointestinal metastases in breast cancer patients is probably underestimated owing to the non-specific presenting symptoms and death of patients caused by other more obvious metastases. The predominant histological subtype of gastrointestinal metastases of breast cancer is invasive lobular carcinoma and the median interval from diagnosis of primary breast cancer to gastrointestinal metastases is five years. We report two cases of disseminated breast cancer with gastrointestinal involvement with a rather long survival.  相似文献

Objective: No studies have examined the relationship between caregiver beliefs about the risks of smoking to their own health and caregiver beliefs about the effect of their smoking on their child's health. In the current study, we investigated our proposed risk congruence hypothesis among caregivers who smoke. Specifically, we investigated whether caregivers' self-perceived risk of smoking is directly associated with their perception of the risks of smoking to their child. Method: The sample consisted of 271 regular smokers (≥3 cigarettes per day; Mage = 32.9 years; 214 women) who were caregivers of children with asthma (Mage = 4.9 years) who had a recent visit to the emergency room for their asthma. Three constructs of perceived risk were measured via self-report questionnaires assessing both caregiver perception of smoking risk to self and to child: Precaution Effectiveness, Optimistic Bias, and Perceived Vulnerability. Child asthma-related functional morbidity and home and child secondhand smoke exposure were also assessed. Results: Consistent with our risk congruence hypothesis, self-perceived risk of smoking was significantly associated with perceived risk to child, over and above the child's secondhand smoke exposure and caregiver report of child's asthma symptoms (i.e., asthma-related functional morbidity). Conclusions: These findings should be considered in the design of clinical interventions seeking to influence risk of caregiver behavior on child health.

AIMS: To ascertain the level of perceived difficulty experienced by patients with central vision loss due to juvenile macular dystrophies in the performance of everyday activities. A second objective was to compare their perceived difficulty with that of patients with retinitis pigmentosa (RP) with primarily peripheral vision loss. METHODS: 72 patients with Stargardt disease, cone dystrophy, or cone-rod dystrophy who had visual acuities worse than 20/40 and normal peripheral visual fields rated themselves on their difficulty in the performance of 33 activities encompassing a wide variety of everyday tasks. These findings were compared with the responses of 120 patients with typical RP or Usher syndrome type 2 who had visual acuities of 20/40 or better and peripheral visual field loss. RESULTS: The juvenile macular dystrophy group reported the greatest level of overall self perceived difficulty with activities involving central vision, and lesser and variable degrees of difficulty with items within the mobility, negotiating steps, driving, and miscellaneous categories. Consistent with these findings, there were highly significant correlations between subjects' rated performances of activities involving central vision and the clinical measures of vision, including visual acuity and size of central scotoma. There were fewer significant correlations between perceived performance of activities in the other categories and the clinical measures. In general, those activities that showed significant correlations with the clinical measures of vision for the patients with juvenile macular dystrophies also showed significant differences in the patterns of responses between the juvenile macular dystrophy group and the RP group. Those items which were not correlated with the clinical measures in the juvenile macular dystrophy group tended not to show significant differences in the response patterns between the two groups. CONCLUSION: These results provide insight into the types of perceived difficulties in performing tasks of everyday life in patients with these disorders which affect counselling of these patients.  相似文献

Our purpose was to evaluate the impact of intravenous and oral tocolysis on prolongation of gestation for women with preterm uterine contractions and/or labor. Candidates for evaluation and treatment including women with contractions between 24 and 35 weeks. Two hundred women (group I) without cervical changes met the protocol criteria and 175 women (group II) who presented with or developed cervical changes were treated by protocol. A representative sample of both groups received oral terbutaline maintenance therapy until 37 weeks' gestation. Primary outcome variables included the length of gestation obtained following initial treatment and the preterm birth rate. Women in group II were twice as likely to deliver before 35 weeks, 23% versus 9.5%, respectively, and to have a delivery before 37 weeks' gestation, 45% versus 22%, respectively, (p < 0.05). There was no significant difference in days gained in utero for women on oral terbutaline for either group. Women in group II on oral therapy were more likely to be readmitted and retreated with parenteral tocolysis. In conclusion, oral maintenance tocolysis has no significant impact on further prolongation of pregnancy after intravenous tocolysis.  相似文献

Seventy-nine patients with chronic neuromuscular diseases were examined by psychodiagnostic tests. The most frequently used coping strategies were "compliance and confidence in the physician", "self encouragement", "to relative by comparison" and "problem-solving". Comparison of the test sample and our total sampling group and the groups divided by diagnosis showed more common features than differences in the coping process. This might be caused by similar general problems in chronic diseases. Less "compliance and confidence in the physician" was the only significant difference between the myasthenic patients and the remaining test group. We supposed less treatment possibilities and/or longer duration of illness (remaining test group) to be responsible for this result. Duration of illness in common seems to have an influence on coping. Patients suffering a longer illness showed reduced values in "self encouragement". Common and specific problems and circumstances of illness seem to be more significant for the coping process than the diagnosis. The patients' mood, which we took as a measure for partial aspects of adaptivity of coping, correlated significantly with the strength of the complaints felt. Classification into adaptive and maladaptive coping forms is not possible.  相似文献

We examined the ability of patients with spinal cord injury to undergo adaptations to chronic exercise training (cycle ergometry) invoked by functional electrical stimulation (FES) of the legs. Nine such patients performed incremental and constant work rate exercise before and after exercise training. Exercise sessions averaged 2.1 +/- 0.4/wk, and consisted of 30 min/session of continuous FES recumbent cycling with increasing work rate as tolerated. Peak VO2 and peak work rate significantly improved with training. Peak VO2 was significantly correlated with peak heart rate both before and after training (r = 0.97 pre and 0.85 post, P < 0.01 for both). The time course of the VO2, VCO2 and VE responses to constant-load exercise (unloaded cycling) and in recovery (mean response time MRT) were very long prior to training, and became significantly faster following training. However, there was no correlation between percentage improvement in either MRTon or MRToff for VO2 and the percentage increase in peak VO2. Exercise tolerance in these patients with spinal cord injury appears to be a direct function of the ability to increase heart rate. Further, exercise training can elicit significant improvements in both exercise tolerance and in gas exchange kinetics, even when performed only twice per week. However, these improvements may be accomplished by different mechanisms.  相似文献

Chronic heart failure (CHF) is accompanied by a reduced exercise capacity, and the symptoms can be at least in part explained by qualitative and quantitative changes in the skeletal muscle composition and metabolism. We have correlated the myosin heavy chain (MHC) composition of the gastrocnemius in 20 patients with different degrees of CHF to expiratory gases measured during maximal cardiopulmonary exercise testing, NYHA functional class and echocardiographic parameters. MHC composition was determined electrophoretically in skeletal muscle needle microbiopsies and the percent distribution calculated by laser densitometry. There was no correlation between ejection fraction, left ventricular end-diastolic and end-systolic diameters and MHC composition. The percentage of MHC 1 (slow aerobic isoform) was positively correlated with peak VO2 (r2 = 0.5, p = 0.0004), ventilatory threshold (VT, r2 = 0.33, p = 0.008), and O2 pulse (peak VO2/HR, r2 = 0.40, p = 0.003). There was a negative correlation between MHC 2a and 2b (fast isoforms) and peak VO2 (r2 = 0.38 and 0.37, p = 0.004, respectively), VT (r2 = 0.2, p = 0.05; r2 = 0.34, p = 0.007, respectively) and O2 pulse (r2 = 0.39, p = 0.003; r2 = 0.23, p = 0.03, respectively). NYHA functional class was also negatively correlated with the same parameters (r2 = 0.2, p = 0.01; r2 = 0.4, p = 0.001; r2 = 0.34, p = 0.006, respectively) as well as with MHC 1 (r2 = 0.62, p = 0.0001). A positive correlation was found between NYHA functional class and MHC 2a and 2b (r2 = 0.46, p = 0.001; r2 = 0.41, p = 0.002, respectively). The severity of heart failure is paralleled by a shift of the MHC pattern toward the fast MHC 2b. The correlation between the magnitude of the MHCs shift, from the slow aerobic to the fast type, with both clinical parameters (NYHA functional class) and functional measurements (peak VO2, VT, O2 pulse) of exercise capacity seem to suggest that changes in skeletal muscle composition may play a key role in exercise tolerance in patients with CHF.  相似文献

The efficacy of antifungal prophylaxis with itraconazole capsules and its serum concentrations were evaluated in patients intensively treated for acute leukaemia. A consecutive group of patients without systemic antifungal prophylaxis (January 1993 to August 1994, period 1) was compared with another consecutive group of patients (period 2) who received itraconazole capsules (September 1994 to April 1995 400 mg/day, from May 1995 onwards 600 mg/day). All patients admitted with acute leukaemia and standard or high-dose chemotherapy were included into the study. Clinical endpoint was mortality from proven fungal infection. Seventy-six patients and 148 courses of cytotoxic chemotherapy were analysed in the control group as well as 47 patients and 112 treatment courses in the intervention group. Antifungal prophylaxis led to a significant decrease of mortality from invasive fungal infections (8.8%-0.9%, P = 0.005). The median trough concentration of itraconazole of all measurements was 520 ng/ml (range 230-793) in patients who received 400 mg/day and 760 ng/ml (370-1200) in patients receiving a dosage of 600 mg/day (P = 0.002). These findings suggest that itraconazole is an effective drug for antifungal prophylaxis but also that a considerable number of patients do not reach the desired trough levels (>500 ng/ml) with itraconazole capsules.  相似文献

Various anti-epileptic drugs may affect the immune system. An IgA-depressing effect of carbamazepine has been proposed, but only serum concentrations have been studied. IgA constitutes a small fraction of the serum immunoglobulins, while it is the predominating one in external secretions. In the present study the concentrations of IgA, IgG and IgM in unstimulated saliva were determined by single radial immunodiffusion in 34 patients with partial epilepsy, and being treated with carbamazepine alone. Median salivary IgA concentration in the patients was 208 x 10(-3) g/l, compared to 150 x 10(3) g/l in 41 healthy controls. Salivary IgG and IgM concentrations were also somewhat higher in the patients than in the controls, while the albumin concentrations were similar in the two groups. However, the differences in the immunoglobulin concentrations between patients and controls were not significant at a 5% level. There was no significant correlation between the concentrations of IgA in saliva and serum.  相似文献

Three nulliparous women presented with secondary amenorrhea with no evidence of endocrinopathy and normal skull x-ray. Pulsatile gonadotropin secretion was reduced, but an adequate pituitary gonadotropin reserve was demonstrable with luteinizing hormone-release factor provocation. The administration of bromocryptine was associated with amplification of pulsatile secretion of gonadotropins and was followed, in two of the three, by ovulatory menstruation. It is suggested that bromocryptine should be considered for induction of menstruation in euprolactinemic secondary amenorrhea.  相似文献

The purpose of this study was to determine whether a brace designed to unload varus degenerative knees actually alters medial compartment loads by decreasing the adduction moment. Eleven patients who had arthrosis confined to the medial compartment were fitted with a valgus brace and tested before and after brace wear with pain and function scoring instruments and by automated gait analysis. The biomechanical data from these patients were compared with those from 11 healthy control subjects. Scores from an analog pain scale decreased 48% with brace wear, and function with activities of daily living increased 79%. Mean adduction moment without the brace measured 4.0 +/- 0.8% body weight times height versus 3.6 +/- 0.8% body weight times height when wearing the brace (10% decrease). The mean adduction moment for control subjects was 3.5 +/- 0.6% body weight times height. Thus, the mean adduction moment decreased from approximately one standard deviation from the normal mean to a value that is similar to the control value. Nine of 11 patients had a decrease in the adduction moment with the brace, five of 11 patients had a reduction higher than 10%, and decreases in this moment were as high as 32%. This study shows that pain, function, and biomechanical knee loading can be altered by a brace designed to unload the medial compartment of the knee.  相似文献
