On the assessment of dental health care attitudes in 1986 and 1995, using the dental attitude questionnaire.

OBJECTIVE: To re-establish and update the empirical data obtained in 1986 with the Dental Attitude Questionnaire. DESIGN: In 1995 this questionnaire, presented earlier by Hoogstraten and Broers (1986), was completed in a similar setting using similar subjects as in 1985, to make a comparison between 1986 and 1995 possible. SUBJECTS: 375 persons, all first grade psychology students who participated for additional course credit. Mean age was 21.7 years, 65 per cent were female. RESULTS: Data show a change in oral health care attitudes and a change in the internal consistency of the DAQ subscales, making the present version of the questionnaire inadequate for measuring present oral health care attitudes. CONCLUSION: This study has shown once more the importance of conducting replication studies after relatively long periods of time in order to update the psychometric characteristics of questionnaires.

Structural comparison of a translated dental attitude questionnaire: a factor analytic study.

In 1984 the Dental Attitude Questionnaire (DAQ), an instrument for assessing various aspects of a person's attitude toward oral health care, was presented by STOCKWELL & BANTING. The DAQ consists of six content scales, Cynicism, Health Concern, Motivation, Oral Function, Social Aesthetic and Susceptibility, and two validity scales, Halo and Infrequency. A Dutch translation was presented in 1986 by HOOGSTRATEN & BROERS. In order to replicate the factor analysis on the original DAQ as reported by STOCKWELL & BANTING, the present study was undertaken. The results show a change in factor structure from a three factor solution to a two factor solution. A confirmatory factor analysis shows that the original three factor structure of the DAQ is not present in the data collected with the translated version. To account for this change, some possible reasons are discussed.

Clinical significance of Clostridium difficile and its toxins in faeces of immunocompromised children.

In this study, clinical and laboratory findings were tested for correlation with the presence of Clostridium difficile. The toxigenicity of the isolated strains and the toxins were determined in faecal samples of immunocompromised children admitted to a single room for protective isolation. Using the toxin assay as the gold standard, the culture sensitivity of toxigenic C difficile was 94.1%, the specificity 93.8%, the positive predictive value 62.8%, and the negative predictive value 99.3%. Correction for stools with a positive culture of toxigenic C difficile preceding detection of toxin, resulted in a positive prediction value of 78.4%. A statistically significant association was found between a positive faecal toxin assay and fever, and between a positive culture of toxigenic C difficile and abdominal pain: 42% of the patients with positive toxin assays had fever versus 21% with negative toxin assays, and 66% of the patients with a positive culture for toxigenic C difficile had abdominal pain, versus 22% with negative cultures. Further analysis of the cultures and toxin assays showed no statistically significant association with diarrhoea, fever, white blood cell count, C reactive protein concentrations, or abdominal pain. Based on these findings, it is suggested that immunocompromised children should be treated when toxigenic C difficile is cultured or when toxin is detected in stool samples.

Infection control in patients undergoing mechanical ventilation: traditional approach versus a new development--selective decontamination of the digestive tract.

Nosocomial infections are major causes of morbidity and mortality in critically ill patients. Traditional infection control practices focus on preventing infection by controlling patient exposure to microorganisms within the patient's environment. We discuss these practices, along with the factors and organisms responsible for nosocomial infection in the patient undergoing mechanical ventilation. Despite traditional infection control measures, nosocomial infection continues to be a major problem. In recent years evidence has accumulated that points to bacterial colonization of the oropharynx and gastrointestinal tract as a major source of infection. A new technique, selective decontamination of the digestive tract, is being studied extensively for its ability to control colonization of the oral cavity and the gastrointestinal tract. In the technique nonabsorbable topical antibiotics are applied to the oropharynx and instilled into the stomach, and a short course of an intravenous cephalosporin is included. The technique appears a worthwhile addition to traditional infection control measures.

Azathioprine and subacute myelomonocytic leukemia.

The occurrence of subacute myelomonocytic leukemia is reported in a patient who had been treated with azathioprine for six years because of systemic lupus erythematosus. A review of the literature yielded 16 additional patients with non-lymphocytic leukemia after the use of azathioprine.
