Young adulthood, defined as 17 to 25 years, is a critical period of development. For young adults newly diagnosed with type 1 diabetes, effective communication from a health care provider is critical. This qualitative study used an electronic interview questionnaire focused on health care professional interactions and course of diagnosis for 12 young adults in college who were diagnosed between ages 17 and 25 years. Three themes emerged: 1) a lack of health information specific for the young adult with type 1 diabetes, 2.) emotional turbulence with forward thinking, and 3) needs/concerns of the group. Health care providers need to work to limit barriers in communication and provide a holistic plan of care. 相似文献

Gaucher disease, the inherited deficiency of the lysosomal enzyme glucocerebrosidase, manifests with a continually expanding range of clinical features. Noting that a number of adult patients with type 1 Gaucher disease also had gallstones, we reviewed the clinical records of 66 adult patients evaluated at the National Institutes of Health with type 1 Gaucher disease. Twenty-one patients were identified who had either gallstones or a history of cholecystectomy. Of the 21 patients, 6 were male. The age at which stones were noted ranged from 19 to 70 years (mean 39 years). Thirteen of the patients had a cholecystectomy performed. Several different factors may contribute to the development of gallstones in these patients, including anemia, prior splenectomy, and hepatic involvement. Eleven of the patients were found to have chronic anemia. Fifteen of the patients underwent splenectomy. An increased biliary excretion of glucosylceramide could also contribute to cholelithiasis. To determine whether our findings were specific to our referral population, the medical records of a second series of 80 adult patients of Ashkenazi Jewish ancestry with type 1 Gaucher disease followed in Northern Israel were reviewed. Sixteen of these patients (5 male, 11 female) were also noted to have gallstones. Thus, the frequency of gallbladder involvement in patients with Gaucher disease appears to be greater than previously appreciated. 相似文献

We report the case of a 54-year old woman who presented with a persistent right lower lobe pneumonia followed by cholelithoptysis, 11 months after a laparoscopic cholecystectomy. It is postulated that this was a result of the formation of a subphrenic abscess secondary to intraoperative spillage of gallstones. It is concluded that spillage of gallstones at laparoscopic cholecystectomy is not as benign as previously thought and that efforts to prevent spillage should include scrupulous operative technique, especially in the presence of gallbladder inflammation, and especial care when removing the gallbladder from the abdominal cavity. 相似文献
