OBJECTIVE -To evaluate whether group visits, delivered as routine diabetes care and structured according to a systemic education approach, are more effective than individual consultations in improving metabolic control in non-insulin-treated type 2 diabetes.RESEARCH DESIGN AND METHODS -In a randomized controlled clinical trial of 112 patients, 56 patients were allocated to groups of 9 or 10 individuals who participated in group consultations, and 56 patients (considered control subjects) underwent individual visits plus support education. All visits were scheduled every 3 months. RESULTS -After 2 years, HbA 1c levels were lower in patients seen in groups than in control subjects (P Ͻ 0.002). Levels of HDL cholesterol had increased in patients seen in groups but had not increased in control subjects (P ϭ 0.045). BMI (P ϭ 0.06) and fasting triglyceride level (P ϭ 0.053) were lower. Patients participating in group visits had improved knowledge of diabetes (P Ͻ 0.001) and quality of life (P Ͻ 0.001) and experienced more appropriate health behaviors (P Ͻ 0.001). Physicians spent less time seeing 9 -10 patients as a group rather than individually, but patients had longer interaction with health care providers.

Pyogenic liver abscess (PLA) are space-occupying lesions in the liver associated with high morbidity and mortality. The aim of this study is to review an Italian hospital experience in epidemiological, clinical patterns, and management of PLA.We performed a retrospective, descriptive case series at a single center assessing demographic characteristics, presentation patterns, etiological factors, microbiological etiology, and management for patients treated for PLA between 2000 and 2016.Around 109 patients were identified. The majority of patients presented with fever (73%); right upper abdominal pain in 63.3%, vomiting and nausea in 28.4%. The most common laboratory abnormality among included items was increased C-reactive protein and fibrinogen blood levels, respectively, in 98% and 93.9% of cases. Abdominal ultrasound was the diagnostic investigation in 42.4% of cases; CT scan and MR imaging were performed in 51.1% and 3.3% of cases respectively. We observed blood or pus culture study in 99 cases of which only 53.5% came with positive microbial reports. The most common organism identified was Escherichia coli (26.5%), followed by Streptococcus spp (13.2%). Early antibiotic treatment started on all patients and 66.7% of cases required different approaches, Ultrasound or CT-guided needle aspiration of PLA was performed in 13 patients (11%) and percutaneous abscess drainage was performed on 72 patients (67%).PLA is a diagnostically challenging problem due to nonspecific presenting characteristics. The microbiological yield identified was a typical European spectrum with a preponderance of Escherichia coli infections. Once recognized, percutaneous drainage and antibiotic treatment are the mainstay of management for PLA.

Duplex ultrasound is the first-line diagnostic test for detecting lower limb deep-vein thrombosis (DVT) but it is time consuming, requires patient transport, and cannot be interpreted by most physicians. The accuracy of emergency physician-performed ultrasound (EPPU) for the diagnosis of DVT, when performed at the bedside, is unclear. We did a systematic review and meta-analysis of the literature, aiming to provide reliable data on the accuracy of EPPU in the diagnosis of DVT. The MEDLINE and EMBASE databases (up to August 2012) were systematically searched for studies evaluating the accuracy of EPPU compared to either colour-flow duplex ultrasound performed by a radiology department or vascular laboratory, or to angiography, in the diagnosis of DVT. Weighted mean sensitivity and specificity and associated 95% confidence intervals (CIs) were calculated using a bivariate random-effects regression approach. There were 16 studies included, with 2,379 patients. The pooled prevalence of DVT was 23.1% (498 in 2,379 patients), ranging from 7.4% to 47.3%. Using the bivariate approach, the weighted mean sensitivity of EPPU compared to the reference imaging test was 96.1% (95%CI 90.6-98.5%), and with a weighted mean specificity of 96.8% (95%CI:94.6-98.1%). Our findings suggest that EPPU may be useful in the management of patients with suspected DVT. Future prospective studies are warranted to confirm these findings.

Carcinoids are tumors derived from neuroendocrine cells and often produce functional peptide hormones. Approximately 54.5% arise in the gastrointestinal tract and frequently metastasize to the liver. Primary hepatic carcinoid tumors (PHCT) are extremely rare; only 95 cases have been reported. A 65-year-old man came to our attention due to occasional ultrasound findings in absence of clinical manifestations. His previous medical history, since 2003, included an echotomography of the dishomogeneous parenchymal area but no focal lesions. A computed tomography s c a n p e r fo r m e d i n 2 0 0 5 s h o w e d an enhanced pseudonodular-like lesion of about 2 cm. Cholangiomagnetic resonance imaging identified the lesion as a possible cholangiocarcinoma. No positive findings were obtained with positron emission tomography. Histology suggested a secondary localization in the liver caused by a low-grade malignant neuroendocrine tumor. Immunohistochemistry was positive for anti chromogranin antibodies, Ki67 antibodies and synaptophysin. Octreoscan scintigraphy indicated intense activity in the lesion. Endoscopic investigations were performed to exclude the presence of extrahepatic neoplasms. Diagnosis of PHCT was established. The patient underwent left hepatectomy, followed by hormone therapy with sandostatine LAR. Two months after surgery he had a lymph nodal relapse along the celiac trunk and caudate lobe, which was histologically confirmed. The postoperative clinical course was uneventful, with a negative follow-up for hematochemical, clinical and radiological investigations at 18 mo post-surgery. Diagnosis of PHCT is based principally on the histopathological confirmation of a carcinoid tumor and the exclusion of a non-hepatic primary tumor. Surgical resection is the recommended primary treatment for PHCT. Recurrence rate and survival rate in patients treated with resection were 18% and 74%, respectively.

ObjectiveThere is little evidence to guide treatment strategies for intracerebral hemorrhage on vitamin K antagonists (VKA‐ICH). Treatments utilized in clinical practice include fresh frozen plasma (FFP) and prothrombin complex concentrate (PCC). Our aim was to compare case fatality with different reversal strategies.MethodsWe pooled individual ICH patient data from 16 stroke registries in 9 countries (n = 10 282), of whom 1,797 (17%) were on VKA. After excluding 250 patients with international normalized ratio < 1.3 and/or missing data required for analysis, we compared all‐cause 30‐day case fatality using Cox regression.ResultsWe included 1,547 patients treated with FFP (n = 377, 24%), PCC (n = 585, 38%), both (n = 131, 9%), or neither (n = 454, 29%). The crude case fatality and adjusted hazard ratio (HR) were highest with no reversal (61.7%, HR = 2.540, 95% confidence interval [CI] = 1.784–3.616, p < 0.001), followed by FFP alone (45.6%, HR = 1.344, 95% CI = 0.934–1.934, p = 0.112), then PCC alone (37.3%, HR = 1.445, 95% CI = 1.014–2.058, p = 0.041), compared to reversal with both FFP and PCC (27.8%, reference). Outcomes with PCC versus FFP were similar (HR = 1.075, 95% CI = 0.874–1.323, p = 0.492); 4‐factor PCC (n = 441) was associated with higher case fatality compared to 3‐factor PCC (n = 144, HR = 1.441, 95% CI = 1.041–1.995, p = 0.027).InterpretationThe combination of FFP and PCC might be associated with the lowest case fatality in reversal of VKA‐ICH, and FFP may be equivalent to PCC. Randomized controlled trials with functional outcomes are needed to establish the most effective treatment. Ann Neurol 2015;78:54–62
