    Description / Table of Contents: Zusammenfassung Für ein Seitenkettenpolymeres, das zusätzlich zum teilkristallinen Zustand und zur isotropen Schmelze einen flüssig-kristallinen Zustand aufweist, wurden die Strukturen und Texturen untersucht sowie thermodynamische Eigenschaften. Außerdem wurde die Kinetik der Phasenumwandlungen analysiert. Es zeigt sich, daß die Eigenschaften zwischen denen üblicher Polymerer und denen von niedrigmolekularen flüssigen Kristallen liegen. Insbesondere zeigte sich, daß die Beziehung zwischen molekularer Struktur und Textur von der bei niedrigmolekularen flüssigen Kristallen abweicht, und daß die Taktizität der Kette einen starken Einfluß auf die Eigenschaften nicht nur der kristallinen Phase sondern auch der flüssig-kristallinen Phase ausübt.
    Notes: Summary The structures, textures as well as thermodynamic properties of a side chain polymer exhibiting a liquid crystalline phase in addition to a partially crystalline state and the isotropic fluid state were investigated. Furthermore the kinetics of phase transitions between these states were analyzed. It was found that the properties of this polymer are intermediate between that of low molecular weight liquid crystals and common polymers. In particular it was observed that the relation between the liquid crystalline texture and the structure is different from that of low molecular weight liquid crystals and that the properties of the crystalline and liquid crystalline state depend strongly on the tacticity of the polymer.

    Differences Between Individuals with Self-Reported Irritable Bowel Syndrome (IBS) and IBS-Like Symptoms (1997)

    Notes: Abstract Although there are several symptomclassification systems for irritable bowel syndrome(IBS), for example, the Manning or Rome criteria, therehas been no previous research on how well theseclassifications correspond to each other or to personsdiagnosed with IBS. We examined data from the DigestiveDisorders Supplement of the 1989 National HealthInterview Survey (NHIS) to assess demographic,socioeconomic, and health status characteristics of two groupsof IBS sufferers — those who met the Manning orRome criteria and those who reported having IBS but didnot meet either criteria. The results showed that the overlap between estimates of IBS and personswith IBS-like symptoms depended on the definition ofIBS. There were socioeconomic differences between thetwo IBS groups and higher rates of functional orwork-related activity limitation and health care utilizationfor all IBS groups relative to US national averages. Insummary, these findings indicate that IBS affects alarge portion of the US population, regardless of the definition used to describe thecondition. Our results suggest that there is a largeundiagnosed population with numerous symptoms consistentwith IBS, but further research is required to determine the differences between people who do and donot seek care, their impact on the health care system,and future therapies to reduce symptomatology andsuffering.

    Irritable Bowel Syndrome Symptom Patterns: Frequency, Duration, and Severity (1998)

    Notes: Abstract We examined symptom frequency, duration, andseverity, as well as episode patterns, in 122 adultpatients with irritable bowel syndrome in a 12-weekstudy conducted in the United States, the UnitedKingdom, and The Netherlands. Patients used aninteractive telephone data entry system daily to reportsymptoms. Data from 59 of the patients meeting inclusioncriteria are presented, the remainder having beenexcluded for failing to complete at least 70 days ofsymptom reporting. The majority of patients experiencedat least one symptom on over 50% of the reported days;however, individual symptoms were reported on less than 50% of the days, indicating that symptomssometimes occurred sequentially rather than alwayssimultaneously. On average, patients reportedpain/discomfort on 33% of days, bloating on 28% of thedays, altered stool form or stool passage on 25% and18% of the days, respectively, and mucus on 7% of thedays. The duration of symptoms was relatively short,with pain/discomfort and bloating lasting the longest, an average of five days each per episode. Allsymptoms but one (mucus) were moderately severe on themajority of reported days. Patients experienced an“episode” (defined as a period of days withsymptoms bounded by one or more symptom-free days) on anaverage of 12.4 times during the study, but the durationof these episodes varied greatly among patients. Theseresults further establish the chronic nature of irritable bowel syndrome and the burden thatthis condition imposes on patients.
