Recurrent epulis granulomatosa: A second look

Excision of epulis granulomatosa with diode laser in 8 years old boy.

INTRODUCTION Epulis granulomatosa is a lesion which grows from an extraction socket. It can be misdiagnosed with lesions of the same clinical appearance such as: foreign body or pyogenic granuloma, or as a herniation of the maxillary sinus. The most common treatment is surgical excision. CASE REPORT The present article reports an Epulis granulomatosa which was removed with diode laser (810 nm...

A second look at the second law

It is commonly argued that the spectacular increase in order which has occurred on Earth does not violate the second law of thermodynamics because the Earth is an open system, and anything can happen in an open system as long as the entropy increases outside the system compensate the entropy decreases inside the system. However, if we define ‘‘X-entropy’’ to be the entropy associated with any d...

Bloomier Filters: A Second Look

A Bloom filter is a space efficient structure for storing static sets, where the space efficiency is gained at the expense of a small probability of false-positives. A Bloomier filter generalizes a Bloom filter to compactly store a function with a static support. In this article we give a simple construction of a Bloomier filter. The construction is linear in space and requires constant time to...

Double checking: a second look

RATIONALE, AIMS AND OBJECTIVES Double checking is a standard practice in many areas of health care, notwithstanding the lack of evidence supporting its efficacy. We ask in this study: 'How do front line practitioners conceptualize double checking? What are the weaknesses of double checking? What alternate views of double checking could render it a more robust process?' METHOD This is part of ...
