Abstract

We describe a case of generalized, asymptomatic, chronic annular lichen planus. The centers of the large annular lesions were atrophic and had lost their elasticity. Histologic examination revealed an absence of elastic fiber in the center. Electron microscopy revealed fragmented elastic fibers. Examination of early lesions showed that elastolysis had already begun in the heavy cellular infiltration. We conclude that the annular configuration resulted from the elastolytic activity of the inflammatory cells with the formation of foci of localized acquired cutis laxa.

Multiple sclerosis.

Multiple sclerosis (MS) is a demyelinating disease of the central nervous system that commonly leads to inflammatory and atrophic brain pathology, often causing cognitive impairment. MS-associated cognitive impairment was first described over a century ago. However, with the advent of standardized neuropsychological testing and quantitative brain imaging, the frequency, quality, and correlates of cognitive impairment are better understood. Dementia is rare in MS, although it is known to occur in 10 to 25% of patients. Our data suggest a frequency of 22% among clinic attendees. In addition to the cognitive impairments evident in MS dementia, changes in personality and social behavior also occur. For example, some patients develop euphoria sclerotica and marked deficiency in social empathy, conditions that in combination with executive dysfunction cause considerable hardship for patients and caregivers. These neuropsychiatric manifestations of MS dementia are correlated with magnetic resonance imaging indicators of brain atrophy, including ventricle enlargement, neocortical volume, and normalized whole brain volume. Recent developments in pharmacological treatment for disease progression and management of cognitive symptoms hold promise for patients suffering from the degenerative aspects of MS.

Inflammation, atrophy, and gastric cancer.

The association between chronic inflammation and cancer is now well established. This association has recently received renewed interest with the recognition that microbial pathogens can be responsible for the chronic inflammation observed in many cancers, particularly those originating in the gastrointestinal system. A prime example is Helicobacter pylori, which infects 50% of the world's population and is now known to be responsible for inducing chronic gastric inflammation that progresses to atrophy, metaplasia, dysplasia, and gastric cancer. This Review provides an overview of recent progress in elucidating the bacterial properties responsible for colonization of the stomach, persistence in the stomach, and triggering of inflammation, as well as the host factors that have a role in determining whether gastritis progresses to gastric cancer. We also discuss how the increased understanding of the relationship between inflammation and gastric cancer still leaves many questions unanswered regarding recommendations for prevention and treatment.
