PURPOSE OF REVIEW: Cholangiocarcinoma is a rare biliary adenocarcinoma associated with poor outcomes. Cholangiocarcinoma is subdivided into extrahepatic and intrahepatic variants. Intrahepatic cholangiocarcinoma is then further differentiated into (1) peripheral mass-forming tumors and (2) central periductal infiltrating tumors. We aimed to review the currently known risk factors, diagnostic tools, and treatment options, as well as highlight the need for further clinical trials and research to improve overall survival rates...

Human transmissible spongiform encephalopathies (TSEs), or prion diseases, are invariably fatal conditions associated with a range of clinical presentations. TSEs are classified as sporadic [e.g. sporadic Creutzfeldt-Jakob disease (sCJD), which is the most frequent form], genetic (e.g. Gerstmann-Straussler-Scheinker disease, fatal familial insomnia, and inherited CJD), and acquired or infectious (e.g. Kuru, iatrogenic CJD, and variant CJD). In the past, brain imaging played a supporting role in the diagnosis of TSEs, whereas nowadays magnetic resonance imaging (MRI) plays such a prominent role that MRI findings have been included in the diagnostic criteria for sCJD...

A tumor composed of large eosinophilic cells in the liver raises concern for hepatocellular carcinoma, which is typically composed of such cells. However, there are other tumors, both primary and metastatic, that may be composed predominantly of large epithelioid cells. Distinction of these tumors from hepatocellular carcinoma and from each other is of obvious importance for patient management. Similarly, a clear cell tumor anywhere in the body triggers suspicion for renal cell carcinoma. However, other tumors, including hepatocellular carcinoma can rarely be composed entirely of cell cells and the distinction of these from one another, and of primary from metastatic disease is vital...

Being diagnosed with and treated for cancer is highly stressful and potentially traumatic. An extensive literature has evaluated the prevalence, predictors, and correlates of cancer-related post-traumatic stress disorder (PTSD) symptoms and diagnoses. In this qualitative review of cancer-related PTSD literature, we highlight conceptual, methodological, and diagnostic issues, and identify clinical implications and areas for future research. Cancer-related PTSD has been documented in a minority of patients with cancer and their family members, is positively associated with other indices of distress and reduced quality of life, and has several correlates and risk factors (eg, prior trauma history, pre-existing psychiatric conditions, poor social support)...

OBJECTIVES: In this study, we aimed to evaluate the usefulness of a new parameter -ratio of the biggest tumor diameter to total tumor diameter- for the differentiation of agressive and favorable papillary thyroid microcarcinomas (PTMC). MATERIALS AND METHODS: The diameter of the biggest tumor focus was taken as the primary tumor diameter. Total tumor diameter was calculated as the sum of the maximal diameter of each lesion. Ratio of primary tumor diameter to total tumor diameter was defined as tumor diameter ratio (TDR)...

: The hippocampus is a small but complex anatomical structure that plays an important role in spatial and episodic memory. The hippocampus can be affected by a wide range of congenital variants and degenerative, inflammatory, vascular, tumoral and toxic-metabolic pathologies. Magnetic resonance imaging is the preferred imaging technique for evaluating the hippocampus. The main indications requiring tailored imaging sequences of the hippocampus are medically refractory epilepsy and dementia...

Self-report is typically used to differentiate between asymptomatic neurocognitive impairment (ANI) and mild neurocognitive disorder (MND) in the assessment of HIV-associated neurocognitive disorders (HAND). Yet, it is unclear whether the lack of self-reported functional impairments in individuals with ANI is indicative of a genuine absence of functional impairment, or of inaccurate self-reports. In the present study, we examined the relationship between previously validated self-report (patient's assessment of own functioning inventory; instrumental activities of daily living inventory) and performance-based (the Texas Functional Living Scale) measures of functional abilities in 112 virologically-controlled HIV-infected, and 40 well-matched, HIV-uninfected participants...

Differentiated carcinomas of the thyroid gland usually have a good prognosis with prognosis often discussed in terms of 20 year survival. Nevertheless its 10-year-survival rate decreases when accompanied by distant metastasis. Follicular thyroid cancer (FTC) is the second most common thyroid cancer and usually presents with a solitary thyroid nodule with or without cervical lymphadenopathy. Distance metastasis at initial diagnosis is seldom observed with incidence range from 1 to 9%. In cases of bone metastasis, the incidence is only 2-3% and weight-bearing skeleton is preferentially affected...

The B-cell activation markers CXCL13, sCD23, sCD27, and sCD30 are associated with future lymphoma risk. However, a lack of information about the individual dynamics of marker-disease association hampers interpretation. In this study, we identified 170 individuals who had donated two pre-diagnostic blood samples before B-cell lymphoma diagnosis, along with 170 matched cancer-free controls from the Northern Sweden Health and Disease Study. Lymphoma risk associations were investigated by subtype and marker levels measured at baseline, at the time of the repeated sample, and with the rate of change in the marker level...

OBJECTIVE: Current non-invasive diagnostic tests can distinguish between pancreatic cancer (pancreatic ductal adenocarcinoma (PDAC)) and chronic pancreatitis (CP) in only about two thirds of patients. We have searched for blood-derived metabolite biomarkers for this diagnostic purpose. DESIGN: For a case-control study in three tertiary referral centres, 914 subjects were prospectively recruited with PDAC (n=271), CP (n=282), liver cirrhosis (n=100) or healthy as well as non-pancreatic disease controls (n=261) in three consecutive studies...

Cephalic tetanus is defined as a combination of trismus and paralysis of one or more cranial nerves. Since it is a rare cause of facial nerve palsy, it is often overlooked as a differential diagnosis. We present the case of a 75-year-old man admitted to our emergency department with left facial nerve palsy, left ptosis and dysphagia 2 weeks after a head laceration. Soon after admission, he was orally intubated because of massive aspiration. A delayed diagnosis of cephalic tetanus was reached only when he was extubated and trismus and risus sardonicus were identified in addition to facial nerve palsy...

OBJECTIVES: Alzheimer's disease (AD) is the most common cause of dementia in elderly persons. Since the pathology of AD develops slowly from a preclinical or early phase into a fully expressed clinical syndrome, at the time of diagnosis the disease has been progressing for many years. To facilitate the early diagnosis of AD, we performed protein profiling of blood in patients with mild AD as defined by the Functional Assessment Staging (FAST) scale. METHODS: Plasma samples from mild AD patients and healthy controls were analyzed using two-dimensional differential gel electrophoresis (2D-DIGE) combined with matrix-assisted laser desorption ionization time-of-flight tandem mass spectrometry (MALDI-TOF/TOF/MS) followed by peptide mass fingerprinting...

Virological and serological surveys have documented that H1N1/2009, avian-origin canine H3N2 (cH3N2), seasonal human-origin H3N2 (hH3N2), and equine-origin H3N8 influenza viruses are consistently circulating in dogs. In the present study, a multiplex reverse-transcriptase polymerase chain reaction (mRT-PCR) assay was developed for simultaneous detection and differentiation of these influenza viruses. Four primer sets were designed to target the hemagglutinin genes of H1N1/2009, cH3N2, hH3N2, and H3N8 canine influenza viruses (CIVs)...

Transient elastography quantifies the propagation of a mechanically generated shear wave within a soft tissue, which can be used to characterize the elasticity and viscosity parameters of the tissue. The aim of our study was to combine numerical simulation and clinical assessment to define a viscoelastic index of liver tissue to improve the quality of early diagnosis of liver fibrosis. This is clinically relevant, as early fibrosis is reversible. We developed an idealized two-dimensional axisymmetric finite element model of the liver to evaluate the effects of different viscoelastic values on the propagation characteristics of the shear wave...

OBJECTIVE: The prevalence of Celiac Disease (CD) has increased significantly in recent years, and risk prediction and early diagnosis has become imperative especially in at risk families. In a previous study, we identified individuals with CD based on the expression profile of a set of candidate genes in peripheral blood monocytes. Here we evaluated the expression of a panel of CD candidate genes in peripheral blood mononuclear cells (PBMCs) from at risk infants long time before any symptom or production of antibodies...

BACKGROUND: Liver enzymes are released from hepatocytes into circulation and their activity can be measured in the blood. We examined whether the plasma activity of the liver enzyme ornithine carbamoyltransferase, determined by a novel liquid chromatography-mass spectrometry (LC-MS/MS) assay, could be utilized for the detection of OTC deficiency (OTCD), an X-linked inborn error of the urea cycle. METHODS: The plasma ornithine carbamoyltransferase (OTC) activity was assayed in the reverse reaction using isotopically labeled citrulline-d4 as a substrate and by determination of the product, ornithine-d4, by LC-MS/MS analysis...

A 9-month-old, captive-bred, female tawny eagle (Aquila rapax) presented with a nonpainful, firm, nodular structure attached to the digital extensor tendon. The mass was surgically resected without complications and was submitted for histopathologic examination. Grossly, cut surfaces of the lesion had chalky-white deposits. Histologically, the resected tissue was identified as calcinosis circumscripta. No recurrence was observed in follow-up after 6 and 12 months. To our knowledge, this is the first case of calcinosis circumscripta in a bird involving a limb extremity, similar to the presentation recognized more commonly in domestic animals...

While behavioral symptoms are both early and prevalent features of behavioral variant frontotemporal dementia (bvFTD), they can be present in other types of dementia as well, including Alzheimer's disease (AD) and even mild cognitive impairment (MCI). The Frontal Behavioral Inventory (FBI) was specifically developed to capture the behavioral and personality changes in bvFTD; it has also been modified into a self-administered caregiver questionnaire (FBI-mod). We examined the utility of the FBI-mod in differentiating bvFTD (n = 26), primary progressive aphasia (PPA) (n = 7), AD (n = 53), and MCI (n = 50) patients, and investigated how the FBI-mod may be associated with neuropsychological measures...

Since the description of cryptogenic organising pneumonia (COP) in 1983 by Davison et al. and the subsequent report on bronchiolitis obliterans organising pneumonia (BOOP) by Epler et al., some reports have been published regarding the imaging features of organising pneumonia (OP). In this pictorial review, we aim to describe different manifestations of OP on high-resolution computed tomography (HRCT) accompanied by their histopathological correlations for a better comprehension of the radiological findings pathomechanism...
