Abstract

Expression of Proliferating cell nuclear antigen (PCNA) was evaluated in formalin-fixed, paraffin-embedded normal and abnormal cervical squamous epithelia using immunoperoxidase stains and PC10 monoclonal antibody to PCNA. PCNA was exclusively expressed in the parabasal and basal layers of normal ectocervix and a similar pattern was seen in nine of the 11 cases with squamous metaplasia. Examples of cervical dysplasia showed expression in higher layers of cervical epithelium, corresponding to the degree of dysplasia. Increased staining was seen in condylomas and markedly reduced staining with atrophy. The percentage of basal cells that stained increased progressively from atrophic to normal, to condylomatous, to dysplastic epithelia. Proliferative activity can be satisfactorily assessed in formalin-fixed cervical epithelia using PC10 PCNA antibody. This assessment can be of potential diagnostic use in difficult cases.

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.
