Carbohydrate counting of food

Carbohydrate counting is a principal strategy in nutritional management of type 1 diabetes. The Nutri-Learn buffet (NLB) is a new computer-based tool for patient instruction in carbohydrate counting. It is based on food dummies made of plastic equipped with a microchip containing relevant food content data. The tool enables the dietician to assess the patient's food counting abilities and the patient to learn in a hands-on interactive manner to estimate food contents such as carbohydrate content.

Glucagon-like peptide-1 versus somatostatin receptor targeting reveals 2 distinct forms of malignant insulinomas

Glucagon-like peptide-1 (GLP-1) receptor imaging is superior to somatostatin receptor subtype 2 (sst(2)) imaging in localizing benign insulinomas. Here, the role of GLP-1 and sst(2) receptor imaging in the management of malignant insulinoma patients was investigated.

[Diagnosis and therapy of hyperthyreosis]

Hyperthyreosis, diabetes and calcium disorders are frequent endocrine diseases that are often encountered by the primary care physician. The diagnosis of hyperthyreosis can be established by many different laboratory and analytical tests. However, the clinical context can often guide a specific diagnostic approach. Graves disease and toxic adenomas are the most frequent causes of hyperthyreosis. Diagnosis of Graves disease is most frequent between age 35 and 60 and about 10-20% of patients show already initially signs of endocrine orbithopathy. Measurement of thyroid stimulating immunoglobulins (TSI) is especially valuable in unclear cases. Toxic adenomas are always diagnosed by thyroid uptake studies. Rare causes of hyperthyreosis include thyreoiditis, which is characterized by transient hyperthyreosis (<2 months), and thyrotoxicosis factitia. Here, we discuss diagnosis and therapy of different causes of hyperthyreosis based on three clinical examples.

Sustained impact of electronic alerts on rate of prophylaxis against venous thromboembolism

Advanced electronic alerts (eAlerts) and computerised physician order entry (CPOE) increase adequate thromboprophylaxis orders among hospitalised medical patients. It remains unclear whether eAlerts maintain their efficacy over time, after withdrawal of continuing medical education (CME) on eAlerts and on thromboprophylaxis indications from the study staff. We analysed 5,317 hospital cases from the University Hospital Zurich during 2006-2009: 1,854 cases from a medical ward with eAlerts (interventiongroup) and 3,463 cases from a surgical ward without eAlerts (controlgroup). In the intervention group, an eAlert with hospital-specific venous thromboembolism (VTE) prevention guidelines was issued in the electronic patient chart 6 hours after admission if no pharmacological or mechanical thromboprophylaxis had been ordered. Data were analysed for three phases: pre-implementation (phase 1), eAlert implementation with CME (phase 2), and post-implementation without CME (phase3). The rates of thromboprophylaxis in the intervention group were 43.4% in phase 1 and 66.7% in phase 2 (p<0.001), and increased further to 73.6% in phase3 (p=0.011). Early thromboprophylaxis orders within 12 hours after admission were more often placed in phase 2 and 3 as compared to phase 1 (67.1% vs. 52.1%, p<0.001). In the surgical control group, the thromboprophylaxis rates in the three phases were 88.6%, 90.7%, 90.6% (p=0.16). Advanced eAlerts may provide sustained efficacy over time, with stable rates of thromboprophylaxis orders among hospitalised medical patients.
