Conflicts between physicians and families about end-of-life decisions create challenging and emotionally difficult situations. In this article, we propose a "differential diagnosis" of such conflicts, distinguishing and describing the characteristics of families, physicians, and organizations and society that contribute to the "etiology" of the situation, as well as strategies for "diagnosing" ...

Scleral inflammatory disease, a relatively common disease of the eye, is demonstrable on CT. Because of its unilateral and sometimes focal involvement, it may be mistaken for more serious diseases, both clinically and by CT. In particular, the clinical difficulties in diagnosing posterior scleritis have led to enucleations when such entities as melanoma and metastasis were suspected. We report ...

BACKGROUND Food insecurity is a major public concern that occurs when nutritional needs are not met, incorporates psychological and physiological coping mechanisms, and can range from basic concern over obtaining food to severe malnutrition. This study was performed to explore differences in female and male respondent psychometric characteristics of a locally adapted Brazilian Household Food Se...

Lipschütz ulcer is a rare cause of vulvar ulcerous diseases and it is often underdiagnosed, probably because of the lack of knowledge about this diagnosis. The aim of this article is to review the pathogenesis, clinical presentation, differential diagnosis and management of this entity.

Syncope is a condition often misdiagnosed as epileptic seizures. However, the differential diagnosis between both conditions can be quite difficult, even for well-trained physicians. Four cases of epilepsy and/or syncope are reported, to exemplify this situation. Each case is discussed individually, and the confounding factors are analyzed.

Infants with the chief complaint of crying can present a diagnostic dilemma to the health care provider. This article discusses the differential diagnosis and management of the crying infant.

BACKGROUND Rasch analysis with a focus on Differential Item Functioning (DIF) is increasingly used for examination of psychometric properties of health outcome measures. To take account of DIF in order to retain precision of measurement, split of DIF-items into separate sample specific items has become a frequently used technique. The purpose of the paper is to present and summarise recent adva...

PILONIDAL SINUS OF NOSE – A DIAGNOSTIC DILEMMA (Abstract): We report an unusual case of pilonidal sinus of the nose, which presented to us as a diagnostic dilemma. Our initial differential diagnosis of a nasal dermoid was overruled by histopathology of the surgical specimen. We discuss the etiological possibilities, the pathogenesis and the histopathological characteristics of a pilonidal sinus...

We investigate the relationship between discrete and continuous time in dynamic physical systems. Employing the common-sense picture behind derivatives, differential equations are translated into discrete-time analogues. The properties of qualitative simulation in discrete time are discussed. It is flirthennore shown that discrete time can be embedded in continuous time in a natural way without...
