Objective: To analyse the clinical features of uncinate process carcinoma of the pancreas and the diagnosis and treatment of this malignancy.
Method: Fifty-nine patients with pancreas uncinate process carcinoma treated from January 1998 to September 2002 at our hospital were analysed retrospectively.
Results: Major symptoms of these patients were upper abdominal pain accompanied with lumbar pain, body weight loss and jaundice. Thirty-seven patients received regional pancreaticoduodenectomy (RP), 16 partial resection of the superior mesenteric vein-portal vein (SMV-PV) or superior mesenteric artery (SMA) and reconstruction, 1 anhydrous alcohol injection in the celiac nerve plexus, regional chemotherapy via a chemotherapy pump, and liver biopsy, and 5 no operation. The survival of the patients after operation was 2-46 months (median 12.1 months). Eleven patients are still alive with a longest survival of 46 months. The 1- and 3-year survival rates were 37.7% and 5.6%.
Conclusions: Pancreas uncinate process carcinoma invading the adjacent SMV/SMA-PV causes difficulty in early diagnosis and poor prognosis, which are related to its location, not tumor's aggressive nature. This carcinoma has a high resection rate of 89.8%.

Background: Right temporal variant frontotemporal dementia (rtvFTD), a new recognized entity among the FTD-spectrum, is characterized by right anterior temporal lobe (rATL) atrophy and a peculiar clinical presentation, involving face and emotions recognition, memory, and naming deficits and behavioral disturbances. Clinical diagnosis is challenging, since rtvFTD shares features with both the behavioral variant FTD (bvFTD) and the semantic variant primary progressive aphasia (svPPA), and there is no consensus yet on its designation and characterization. Although rATL neurodegeneration is a hallmark of this syndrome, only a few studies investigated patterns of gray matter (GM) atrophy.

Method: To examine the degree to which each pathology affects WM integrity in a more diverse non-demented cohort, Aβ and tau PET, diffusion-weighted imaging (DWI), and cognition (memory and executive function composites) were examined from the U.S.

Background: The presence of cortical amyloid-beta pathology is associated with white matter microstructural changes in Alzheimer's disease (AD), especially in tracts associated with memory. However, the relationships between tract-specific neuroinflammation and plasma markers of astrogliosis is underexamined; similarly, the involvement of tau neurofibrillary tangles is unclear in neuroinflammation. Here, we investigated the association between plasma glial fibrillary acidic protein (GFAP) and changing proportion of intravoxel freewater-a microstructural change associated with neuroinflammation-within white matter tracts vulnerable to AD.

Elevated IL-17A-Secreting Regulatory T Cells in Sinonasal Tissues of Chronic Rhinosinusitis with Nasal Polyps.

During nasal polyp (NP) development, activated T cells differentiate into T helper (Th) 1, Th2, and Th17 cells. Additionally, regulatory T cells (Tregs) that have an immune suppressive function are involved in the pathophysiology of chronic rhinosinusitis (CRS) with NP (CRSwNP). Tregs can act as effector cells that produce inflammatory cytokines, such as interleukin (IL)-17A.
