Although surgically created aortopulmonary (AP) shunts are uncommon in the adult congenital heart disease population, they are often used in patients with pulmonary atresia. For these patients, the shunt is a vital supply of pulmonary blood flow and thus obstruction of the shunt may lead to pulmonary hypoperfusion and hypoxia thereby increasing morbidity and mortality. This report describes a safe and effective method of stenting the conduit with the hemodynamic support of peripheral cardiopulmonary bypass (PCB). Prior to the procedure, a multimodality assessment of a stenosis in a kinked AP conduit using computed tomography, angiography, intravascular ultrasound (IVUS), and pressure wire assessment (PWA) was utilized. While PCB, IVUS, and PWA have all been used to great effect in various clinical scenarios, the combined use of these techniques has not been previously been described in the setting of intervention in adult congenital heart disease. © 2013 Wiley Periodicals, Inc.  相似文献

We describe 3 siblings with muscular ventricular septal defects, two requiring surgical closure. One of their offspring had a rare congenital aneurysm of the muscular ventricular septum, also requiring surgery. Another had a small muscular ventricular septal defect which closed spontaneously. Their father had echocardiographic evidence suggestive of a closed muscular defect. Paternal cousins have had ventricular septal defect, hypertrophic cardiomyopathy, and tetralogy of Fallot. There was no evidence of 22q11 deletion. Although ventricular septal defects are the most common congenital heart defect, such familial clustering is uncommon. The distribution of cases in this family suggests autosomal dominant inheritance. With echocardiography, and more precise diagnosis of defects which close, a larger genetic component may be revealed in other families.  相似文献

Background Colonoscopy is an effective modality for colorectal cancer screening. The objectives of this study were to identify colorectal cancer knowledge and barriers to screening colonoscopy in the general US population. Methods Data was obtained from the health information national trends survey (HINTS I). The dataset (n = 6369) examined the influence of age, race, gender, education, income, media usage, and interactions with health care providers on knowledge, attitudes, and behavior regarding colonoscopic screening for colorectal cancer. Results The term ‘colonoscopy’ was recognized by 80% of participants (over the age of 35), however only 35% of respondents perceived it as a major method for colon cancer screening. Hispanics had the least awareness of colonoscopic screening (16% versus 39% non-Hispanic). Female gender, education, and income all correlated with knowledge and use of colonoscopic screening. There was a positive correlation between media usage and having a colonoscopy (r = 0.095, p < 0.01). Having a health care provider was strongly correlated with having undergone a colonoscopy (r = 0.249, p < 0.01). Reasons for not having a colonoscopy were ‘no reason’ (29%), ‘doctor didn’t order it’ (24%), and ‘didn’t know I needed the test’ (15%). Personalized materials were the preferred media for receiving cancer-related information. Conclusions Knowledge of and participation in screening colonoscopy is low in the US population, especially among Hispanics. The most important immediate action is to increase physician referral for screening colonoscopy. Education materials focused on specific sociodemographic segments and targeted communication campaigns need to be developed to encourage screening.  相似文献

According to the Office of Minority Health, an estimated 4.9 million people living in the United States consider themselves American Indian or Alaska Native, either alone or in combination with one or more races/ethnicities. American Indians or Alaska Natives comprise a racial/ethnic group experiencing serious health disparities, with little if any improvement in health outcomes over the past several decades. This study was designed to explore use of the Internet as a health information source among American Indians in the Central Plains region of the United States. The authors recruited 998 Natives in the region from May 2008 to December 2009 at powwows, health fairs, focus groups, career fairs and conferences, and other social and cultural events, and asked them to complete a self-administered survey. Although compared with data from the general population, American Indians or Alaska Natives in this sample may seem to be more frequent Internet users, their use of modern wireless devices is limited, and their use of the Internet to access health information is lower in comparison with the adult U.S. population. Natives living in the Central Plains region face generational differences in general and health-related use of the Internet. Inadequate availability of culturally appropriate health information websites may drive American Indians or Alaska Natives toward search engines and general information websites.  相似文献

This study aimed to compare cognitive function of cancer pain patients being given opioids during their cancer treatment (n = 14) with that of patients receiving treatment without opioids (n = 12). Correlations between cognitive function, pain intensity, and opioid dose were analyzed. Patients were assessed 3 times in a 1-month period, using the Trail-Making Test, Mini-Mental State Examination, Digit Span, and Brief Cognitive Screening Battery. Opioid use was not associated with clear cognitive impairment. Patients being treated without opioids did perform better in the Digit Span Test reverse-order test (P = .029) and the clock drawing test (P = .023), but the differences arose in just 1 assessment in each case. Pain intensity correlated negatively with scores in the Mini-Mental State Examination (P = .001) and some Brief Cognitive Screening Battery tests (incidental recall, immediate recall, and late recall; P 相似文献

Objective and methods  In order to better understand the effects of opioids on the cognitive function in cancer pain patients, a literature search was performed in PubMed, EMBASE, PsycInfo, CINAHL and Lilacs databases. Ten controlled trials were selected and classified according to the study design, the level of evidence, and opioid regimen. Result  Six studies reported association between poor cognitive performance (reaction time, attention, balance, and memory) and opioid use. Conclusion  These cognitive deficits were captured with neuropsychological tests; however, their clinical relevance is still uncertain.  相似文献
