Gastro-oesophageal reflux disease: Medical or surgical treatment? Report of an interactive workshop

Gastroesophageal reflux disease (GERD) is the most common disease of the upper gastrointestinal tract. With the introduction of proton pump inhibitors medical treatment of GERD has been significantly improved. However, the development of laparoscopic antireflux surgery resulted in an increasing interest of surgeons in this disease. An interactive meeting was organized in order to develop an agreement between gastoenterologists and surgeons regarding therapeutic decisions and this is the main topic of this paper.     

Socio-cognitive skills as a determinant of life satisfaction in aged persons.

The purpose of this study was to explore the viability of a revised model of elderly life satisfaction, specifically evaluating the contribution of socio-cognitive skills. The role of such skills in relation to life satisfaction among aged persons has not been explored in research to date. Pilot data gathered from 60 community-living aged individuals indicated that numerous variables (e.g., subjective/objective health, education, financial satisfaction, role participation, subjective integration) significantly correlated with life satisfaction. However, the combined effects of two variables, persons' feelings of loneliness and isolation from their families and a measure of socio-cognitive skill, accounted for 49 percent of the variability in elderly life satisfaction. The effects of each on life satisfaction were unique however. Implications of these data and possible interventions for increasing elderly persons' life satisfaction are discussed.     

Validation of the survey of work styles: a profile measure of the type A behaviour pattern

The present study compares the Type A classification accuracy of the Jenkins Activity Survey (JAS), The Framingham Type A Scale, and a new Type A behaviour pattern (TABP) measure. The Survey of Work Styles (SWS), a self-report measure of the TABP, was developed using a construct approach to scale construction. It consists of six content scales. Impatience, Anger, Work Involvement, Time Urgency, Job Dissatisfaction and Competitiveness. In addition to the six content scales, a seventh scale, Scale A, is comprised of items empirically selected to relate to the Rosenman Structured Interview. In the present study the SWS was found to be significantly related to both the JAS, and the Framingham Type A Scale in a sample of 163 business managers. Median reliability of the SWS subscales was 0.82, and for the total scale 0.90. Discriminant function analysis using cross validational jackknifing procedures resulted in a classification accuracy of 83% of the Type A managers in relation to the Structured Interview. Classification using the SWS was found to correlate significantly higher with the Structured Interview than did either classification with the JAS or with the Framingham Type A Scale. Modal profile analysis yielded three independent bipolar typal dimensions, indicating that a single dimension or classification of the TABP represents an oversimplification of a complex behaviour pattern. These results support the reconceptualization of the TABP in terms of distinct facets and profile patterns.     

Fluorescein angiographic findings in three patients with long-term intravitreal liquid silicone.

The long-term retinal effects of intravitreal liquid silicone (ILS) remain controversial. In this study fundus fluorescein angiographic findings in three patients with long-term ILS are presented. Sluggish or absent blood flow was observed in retinal arterioles that lay in close proximity to the ILS, and the arterioles themselves appeared narrowed. It is suggested that ILS may have a long-term effect on the retinal vasculature, owing either to direct vascular damage, secondary to damage to the neuroretina, or to the ILS preventing diffusion of oxygen into the vitreous cavity.     

Melbourne trial of adjuvant immunotherapy in operable large bowel cancer

A controlled randomized clinical trial was undertaken to assess the ability of combined non-specific and specific immunotherapy to alter the disease-free interval and overall survival of patients with Stage B or C large bowel cancer. The immunotherapy consisted of a 2 year programme of vaccinations with BCG and neuraminidase-treated autologous tumour cells. Three hundred and one patients entered the trial. At 5 years of follow-up there is no evidence that this form of immunotherapy can alter either the disease-free interval or survival in this group of patients.     

Successful treatment of empyema thoracis with polymethylmethacrylate antibiotic-impregnated beads in the guinea pig

Two hundred nine Duncan-Harley guinea pigs had intrathoracic inoculation with 10(8) Staphylococcus aureus, accompanied by blood and umbilical tape. One hundred fifty-two animals were excluded because of clinical recovery, early death, or complications related to intrathoracic polymethylmethacrylate (PMMA) bead placement. The remaining 57 animals had clinical signs of empyema thoracis and were the subjects of this study. Group I animals (N = 24) served as the controls and had no therapy. Group II animals (N = 14) were treated by intrathoracic placement of placebo PMMA beads. Group III animals (N = 19) were treated by intrathoracic placement of tobramycin sulfate-impregnated PMMA beads. There were no differences between the groups in pleural reaction or pneumonia scores. These findings demonstrate a similar host response to the established infection. Group III, however, had a higher sterilization rate than Groups I and II (p less than 0.05), a finding underlining the therapeutic effect of tobramycin-treated PMMA beads. We conclude that intrathoracic local antimicrobial therapy with slow-release tobramycin-impregnated PMMA beads may enhance empyema treatment by increasing the rate of local sterilization. More experiments are necessary to assess the efficacy of this potentially important therapeutic arm for the treatment of thoracic empyema.     

The conservative management of primary breast cancer

A comparison was made of the methods used to manage primary breast cancer in Western Australia during 1978 and 1984. It was noted that the incidence of breast-conserving surgery increased from 5% in 1978 (16 out of 313 patients) to 14% in 1984 (59 out of 431 patients). Of the 59 patients in the latter group, 37 (63%) did not receive adjuvant radiotherapy. This is a matter of concern as failure to use adjuvant radiotherapy, subsequent to breast-conserving surgery, may lead to an increased incidence of locally recurrent disease.
