A new approach to teaching Normal Growth and Development to preclinical medical students is described. By using specially constructed multidisciplinary clinical simulations as training and evaluation devices, students were gradually and simultaneously exposed to: (1) subject matter; (2) the concept of multidisciplinary health care delivery; and (3) the objectives, strategies, and techniques of problem solving and diagnostic reasoning that characterize experienced physicians. The course, designed by a child psychiatrist and medical educators, was taught by a multidisciplinary teaching team drawn from faculty and health care representatives. Student evaluations of the course were favorable. 相似文献

These 8 cases of multiple hamartoma syndrome are the first reported in Switzerland. Two men aged respectively of 65 and 28 years presented a cobblestone appearance of the gingiva and of the tongue ("pebbly tongue"), which suggested Cowden disease. This diagnosis was confirmed by the discovery of numberous skin lesions, a thyroid goiter, gastrointestinal polyposis, and a mild skelettal dysmorphosis. The older patient had a grade one carcinoma of the bladder; his son and his daughter presented the syndrome, which was also discovered in the family of the second patient (his father, his brother, his sister and one of her daughters). The ultrastructural study of two skin biopsies demonstrated anomalies of the fibroblasts and collagen fibers. 相似文献

(1) Background: Familial hypercholesterolemia (FH) is a genetic autosomal dominant disorder characterized by elevated levels of low-density lipoprotein cholesterol (LDL) that develops deposits of lipids in the arterial wall. Since it is underdiagnosed and undertreated, the disease has a high risk of premature cardiovascular disease and death. Patients are not always aware of the changes they should make in their diet. Thus, our study aimed to evaluate through a food frequency questionnaire their eating habits. (2) Methods: We included 70 patients with FH and 20 subjects in a control group that were evaluated through a physical examination and blood tests. They also completed a food frequency questionnaire. (3) Results: Throughout our study, we observed several aspects: regardless of age, patients with FH had higher carbohydrate intakes compared to the control group; from the same group, a positive correlation was observed between salami intake and the levels of glucose and glycated hemoglobin. Moreover, the sour cream preference was associated with higher liver function tests. In the control group, we observed a higher intake of pasta and fast food and fewer fruit portions. (4) Conclusions: As far as we know, this is the first study from Romania that evaluated the eating habits of patients diagnosed with FH. Our study reveals that, although patients with FH avoid junk food, they still have a high intake of carbohydrates when compared to the control group. Further research is needed in order to get a comprehensive nutritional evaluation of these patients. 相似文献

The current study examines the predictors of three types of problem-focused coping strategies (i.e., amount of help seeking, pursuing an order of protection, and staying away from the abuser) among battered women. Predictor variables are categorized as abuse characteristics and three types of coping resources (i.e., personal, material, and social coping resources). Data from the Chicago Women's Health Risk Study (N=478) are used. Results show that enactment of problem-focused coping strategies is associated with amount of abuse, severity, harassment, and power and control tactics. Coping resources such as general health, employment, and social support influence enactment of coping strategies. 相似文献

Open in a separate window OBJECTIVESPump thrombosis remains a major challenge in heart failure patients with left ventricular HeartWare assist device. Current International Society for Heart and Lung Transplantation recommendations favour surgical pump exchange over lysis because safety and efficacy of lysis has been controversially reported. This study summarizes our experience on our HeartWare thrombosis prevention strategy as well as thrombolysis through implementation of our institutional standardized HeartWare assist device protocol.METHODSOutcomes of all HeartWare thrombosis patients admitted between 2010 and 2020 were analysed. Thrombolysis therapy using tissue plasminogen activator was used as the first-line therapy in this study and thrombolysis therapy efficacy was defined as freedom from stroke, bleeding, recurrent HeartWare assist device thrombosis or surgical device exchange within 30 days after lysis application.RESULTSA total of 507 patients have been included in this study and 66 patients (13%) collectively developed a first HeartWare-thrombosis after a median of 12 months (8–22 months) after HeartWare implantation. Forty patients were treated with unstandardized lysis, of whom 7 patients had thrombolysis associated complications, such as incomplete thrombus resolution requiring surgical pump exchange in 4 patients, but also intracranial haemorrhage occurring in 3 patients. Three patients died in the non-protocol group. Eight device thrombosis patients were treated according to our protocol, showing no lysis-associated complication.CONCLUSIONSDespite current recommendations, preferring surgical HeartWare pump exchange in thrombosis, thrombolysis therapy for first HeartWare thrombosis can be safe and effective in a standardized protocol setting, including anticoagulation adjustment and intensified blood pressure control management. 相似文献

Little is known about the (co-)occurrence of smoking, alcohol at-risk drinking, physical inactivity and overweight, and the motivation to change these behavioral health risk factors (HRFs) in older general hospital patients with cardiovascular disease. Between October and December 2016, all consecutively admitted patients aged 50 to 79 years were proactively recruited on 3 cardiology wards and asked to participate in a survey on HRFs and behavior change motivation. Of the eligible patients, 80.4% participated in the survey (n = 328). The mean age was 66.5 years (standard deviation 9.0), and 65.5% were male. At least 1 HRF was present in 91.8% (n = 280), at least 2 HRFs in 54.4% (n = 166), and 3 or 4 HRFs in 12.1% (n = 37) of participants. The proportion of older adults who contemplated or were changing or planning to change their behavior to meet health behavior recommendations ranged between 66.0% (smoking) and 93.2% (alcohol consumption). The results indicate a notable co-occurrence of behavioral HRFs in older patients with cardiovascular disease. The majority of older adults were at least considering changing the respective behavior. To prevent and treat diseases efficiently, hospitalization may be a suitable moment for systematic multiple HRF screening and intervention. 相似文献
