Is the Detection of Odontoma Always Comfortable? A Case Report

Abstract Odontomas are the most common type of odontogenic tumors, which are often discovered by routine radiographic images or after taking films to determine the main cause of the tooth failure eruption or malocclusion. The present study aimed to describe a case of misdiagnosis and similarity of foreign body density in the radiographic appearance to odontoma in a 13-yea...

Short stay in general intensive care units: is it always necessary?

Group Knowledge Isn't Always Distributed (neither Is It Always Implicit)

In this paper we study the notion of group knowledge in a modal epistemic context. Starting with the standard de nition of this kind of knowledge on Kripke models, we show that this de nition gives rise to some quite counter-intuitive behaviour. Firstly, using a strong notion of derivability, we show that group knowledge in a state can always, but trivially be derived from each of the agents' i...

High-density lipoprotein: is it always atheroprotective?

High-density lipoproteins (HDLs) are appropriately recognized for their many atheroprotective functions, including reverse cholesterol transport, as well as antioxidant, anti-inflammatory, and antithrombotic effects. Furthermore, the inverse relationship between HDL cholesterol and atherosclerosis is well documented in many populations. However, there is an increasing body of evidence that ther...

A high chromogranin A: Is it always a tumor?

Human chromogranin A (CgA) is a secretory protein that is used as a tissue marker for neuroendocrine tumors (NETs) (1,2). In patients with carcinoids and pheochromocytomas, CgA is a more stable marker than plasma levels of serotonin, catecholamines and their urinary metabolites (3). It may also be elevated due to several other causes; however, the use of proton pump inhibitors (PPIs) is the mos...
