OBJECTIVE: The diagnosis of epilepsy cannot be reliably made prior to a patient's second seizure in most cases. Therefore, adequate diagnostic tools are needed to differentiate subjects with a first seizure from those with a seizure preceding the onset of epilepsy. The objective was to explore spontaneous blood oxygen level-dependent (BOLD) fluctuations in subjects with a first-ever seizure and patients with new-onset epilepsy (NOE), and to find characteristic biomarkers for seizure recurrence after the first seizure...

ADP-ribosylation factor 1 (ARF1) is a small G protein that regulates many cellular processes such as reorganization of the actin cytoskeleton and is highly expressed in various tumor cells and tissues. However, the role of ARF1 in ovarian cancer progression remains unknown. In the present study, we explored the expression patterns of ARF1 in clinical ovarian cancer samples and adjacent noncancerous tissues. The results revealed that ARF1 overexpressed in EOC tissues and cell lines, compared with the adjacent non-tumorous tissues and normal ovarian cells...

Exosomes are nanovesicles formed in the endosomal pathway with an important role in paracrine and autocrine cell communication. Exosomes secreted by cancer cells, malicious exosomes, have important roles in tumor microenvironment maturation and cancer progression. The knowledge of the role of exosomes in tumorigenesis prompted a new era in cancer diagnostics and therapy, taking advantage of the use of circulating exosomes as tumor biomarkers due to their stability in body fluids and targeting malignant exosomes' release and/or uptake to inhibit or delay tumor development...

Malignant tumors account for most sources of ectopic ACTH Cushing syndrome (EA-CS). Early localization of the source and complete removal can be curative and also prevent metastasis. Diagnostic CT is known to perform better than PET/CT (low dose) in characterizing lung pathologies. However, bronchial carcinoids, a common source of EA-CS, may be difficult to detect on chest CT scan especially when it is small and located close to the hilar region. We present a case of EA-CS due to bronchial carcinoid, which was easily seen on Ga DOTANOC PET/CT after a diagnostic chest CT was reported as normal...

A 73-year-old man was referred for F-FDG PET/CT study for staging of biopsy-proven pancreatic adenocarcinoma. The scan demonstrated focal intense FDG uptake in the pancreatic head, localizing the primary tumor. Additional moderate diffuse uptake was seen throughout the pancreas, suggestive of acute pancreatitis. Concurrent diagnostic CT showed diffuse pancreatic hypoenhancement consistent with edema. Serum lipase level was elevated, confirming a diagnosis of acute pancreatitis.

Routine histopathologic examination of hemorrhoidectomy specimens is controversial having been described as not useful and expensive with few of these common cases demonstrating incidental lesions. However, unexpected premalignant and malignant lesions have been detected on excised hemorrhoids. The high-risk human papillomavirus (HR-HPV) types associated with these incidentally identified high-grade lesions are presently unknown. We aimed to identify cases of incidental high-grade anal intraepithelial neoplasia (HG-AIN) and anal squamous cell carcinoma incidentally discovered on hemorrhoidectomy specimens, genotype HR-HPVs from these lesions, and assess p53 and p16 expression by immunohistochemistry to identify risk factors for their development...

REVIEW
Kathrin Halfter, Barbara Mayer
Current decision-guiding algorithms in cancer drug treatment are based on decades of research and numerous clinical trials. For the majority of patients, this data is successfully applied for a systemic disease management. For a number of patients however, treatment stratification according to clinically based risk criteria will not be sufficient. The most effective treatment options are ideally identified prior to the start of clinical drug therapy. This review will discuss the implementation of three-dimensional (3D) cell culture models as a preclinical testing paradigm for the efficacy of clinical cancer treatment...

Quantitative measurement of the material properties (e.g., stiffness) of biological tissues is poised to become a powerful diagnostic tool. There are currently several methods in the literature to estimating material stiffness and we extend this work by formulating a framework that leads to uniquely identified material properties. We design an approach to work with full field displacement data - i.e., we assume the displacement field due to the applied forces is known both on the boundaries and also within the interior of the body of interest - and seek stiffness parameters that lead to balanced internal and external forces in a model...

Biolasers are an emerging technology for next generation biochemical detection and clinical applications. Progress has recently been made to achieve lasing from biomolecules and single living cells. Tissues, which consist of cells embedded in an extracellular matrix, mimic more closely the actual complex biological environment in a living body and therefore are of more practical significance. Here, we developed a highly versatile tissue laser platform, in which tissues stained with fluorophores are sandwiched in a high-Q Fabry-Pérot microcavity...

Numerous studies have contributed to our current understanding of the complex biology of pulmonary tuberculosis and subsequently provided solutions to its control or eradication. Metabolomics, a newcomer to the Omics research domain, has significantly contributed to this understanding by identifying biomarkers originating from the disease-associated metabolome adaptations of both the microbe and host. These biomarkers have shed light on previously unknown disease mechanisms, many of which have been implemented toward the development of improved diagnostic strategies...

Testicular germ cell tumors (TGCT) are a group of heterogeneous, biologically diverse and clinically challenging neoplasms. Despite the relatively low incidence and mortality rates, a subgroup of patients with disseminated disease relapse after conventional therapy and have a dismal prognosis. Moreover, TGCT afflict mostly young men and have therapeutic peculiarities, with some patients showing resistance to cisplatin-based treatments and others being troubled by irreversible side effects, such as infertility...

The description of the Bednar's ulcer is uncommon in the current literature. It has been associated with the traumatic effect of the bottle's nipple and/or no orthodontic soothers while breastfeeding. We present a newborn of 20 days of life attended at the emergency room for irritability, with the only finding on physical examination of two oral ulcers. We describe the clinical presentation, evolution and treatment. The normality of the diagnostic test, clinical characteristics and evolution lead to the diagnosis of Bednar´s ulcer...

BACKGROUND: Unlike rivaroxaban, treatment of patients with pulmonary embolism (PE) with warfarin requires parenteral bridging and coagulation monitoring that may prolong length-of-stay (LOS) and increase hospital costs. AIMS: The aim of this study was to compare LOS, hospital costs and readmissions in PE patients managed through observation stays treated with rivaroxaban or parenterally bridged warfarin. METHODS: Premier Hospital claims data from November 2012 to March 2015 were used to identify patients with a primary diagnosis code for PE managed through an observation stay and with ≥1 claim for a PE-related diagnostic test on day 0-2...

WHAT IS KNOWN AND OBJECTIVE: Glucocorticoid-induced diabetes mellitus (GIDM) increases the risk of diabetes mellitus (DM)-related complications but is generally difficult to detect in clinical settings. The criteria for diagnosing GIDM have not been established. Recently, medical information databases (MIDs) have been used in post-marketing surveillance (PMS) studies. We conducted a pharmacoepidemiological study to develop an algorithm for detecting GIDM using MID. METHODS: We selected 1214 inpatients who were newly prescribed with a typical glucocorticoid, prednisolone, during hospitalization from 2008 to 2014 from an MID of Hamamatsu University Hospital in Japan...

OBJECTIVE: Some people with major depressive disorder (MDD) may be at a pre-onset stage for bipolar disorder (BD), where early identification or prevention efforts may be feasible. We aimed to identify rates and characteristics predictive of transition to BD in prospective follow-up studies of people with MDD. METHODS: Using a systematic search strategy, we identified studies with a diagnostic ascertainment of MDD and BD of an adequate standard, and where the minimum length of follow-up was 6 months...
