RESUMEN
The aim of this prospective randomised study was to assess the effects of tube drainage on postoperative discomfort after the extraction of impacted mandibular third molars. We studied 40 patients (11 men and 29 women) 18 years or older (mean (SD) 21 (3), range 18-29) who required extraction of mandibular third molars. We used a randomised crossover design by which if a drain was inserted on one side, then the other side was managed without a drain on a later occasion. Pain, swelling, and mouth opening were evaluated after 48 h and 7 days postoperatively in both groups. Facial swelling (p=0.001), pain p=0.001), and trismus (p=0.001) were significantly less common in the drained group compared with those not drained. We conclude that the use a tube drain is of benefit in minimising postoperative swelling, pain, and trismus after extraction of mandibular third molars.

The direct costs and health effects of a primary-care-based brief intervention for hazardous alcohol consumption were examined. The total cost of the intervention was calculated from costs associated with: marketing the intervention programme; providing training and support in the use of the intervention materials; physician time required for providing brief advice for 'at-risk' drinkers. The effect of the intervention on health outcomes was expressed in terms of number of life years saved by preventing alcohol-related deaths. This was derived by combining estimates of the impact of the programme if it were implemented nationally with available evidence on the health effects of excess alcohol consumption. Results are based on international trial evidence showing the physical resources required by the intervention and its effectiveness combined with Australian price data. The costs associated with screening and brief advice using the current intervention programme range from Aus$19.14 to Aus$21.50. The marginal costs per additional life year saved were below Aus$1873. The robustness of the model used is supported by an extensive sensitivity analysis. In comparison with existing health promotion strategies the costs and effects of the current intervention are highly encouraging.

AIM: In this clinical study combined surgical and endodontic treatment was performed in 20 cases of crown-root fracture and the outcomes reviewed. METHODOLOGY: Surgical treatment involved a conventional extraction and stabilization technique. Root canal treatment using calcium hydroxide was performed. Before root canal obturation, a calcium hydroxide dressing was maintained for 3 months. RESULTS: Follow-up examinations, which varied between 6 and 36 (mean 14.5) months, showed that there were no radiographic and clinical signs of progressive root resorption, marginal bone loss or periapical disease in all except one case. CONCLUSIONS: The favourable results of this study demonstrate that surgical extrusion in teeth with crown-root fractures may be an alternative treatment to orthodontic extrusion.

This report presents a case of intrusive luxation of immature maxillary central incisors with concomitant uncomplicated crown fractures in an 8-year-old boy. The intruded teeth with open apices were repositioned with surgical extrusion and endodontically treated through use of calcium hydroxide paste. Six months after initiation of apexification, definitive apical stops had formed. The canals were then permanently obturated, and the crowns were restored with composite resin. Clinical and radiographic examination 24 months after the surgical extrusion revealed satisfactory apical healing and healthy supporting tissues.

The cost-effectiveness of strategies to market and train primary care physicians in brief intervention for hazardous alcohol consumption was examined. Physicians were randomly assigned to one of three marketing strategies designed to promote the "uptake" of a brief intervention package for hazardous and harmful alcohol consumption. The strategies were direct mail, tele-marketing, or academic detailing. One hundred and twenty-seven of those physicians who requested the package during the marketing phase (phase 1) and who also agreed to participate in the training and support phase of the project (phase 2) were matched into one of three training and support conditions: training and no support, training and minimal support, training and maximal support. An additional 34 physicians were randomly selected and assigned to a control condition. The ultimate aim of training and support was to maximise physician screening and counselling rates. Tele-marketing was found to be more cost-effective than academic detailing and direct mail in promoting the uptake of the package. For the training and support phase costs and effects increased with the level of support, hence the issue to be considered is whether the additional cost incurred in moving from one strategy to another is warranted given the increase in the level of outcome.

The aim of the present study was to compare the analgesic efficacy of piroxicam-FDDF (fast dissolving dosage form) with naproxen sodium, following bilateral removal of impacted third molars. A double-blind, randomized, crossover, analgesic trial was carried out on 40 patients undergoing surgical removal of one lower third molar at each visit. The analgesic efficacy of a single dose regimen of piroxicam-FDDF (40 mg, Feldene Flash, Pfizer, Turkey) was compared with naproxen sodium (550 mg, Anaprotab, Sanli, Turkey). Pain intensity was measured on a category-rating scale during the 8-h period after drug administration. Each patient evaluated the efficacy of the study medication at 15, 30, 45, 60, 90 and 120 min, and then hourly for up to 8 h of drug ingestion. Additional key efficacy measures were also determined (pain intensity difference [PID], sums of pain intensity difference [SPID], total pain relief [TOTPAR], peak pain relief, number of observations at which pain was half-relieved, overall evaluation of study medication effectiveness, and time to medication with a back-up analgesic). The data were analyzed by paired Student's t-test and one-way analysis of variance (ANOVA). Results are expressed as means +/- SEM, and p < 0.05 was taken as statistically significant. The PID and pain relief scores of the piroxicam-FDDF group were significantly greater than those for the naproxen sodium group at 15, 30, 45 and 60 min (p < 0.01). After 90 min to 8 h, no statistical significance was revealed among the two test groups (p > 0.05). The peak pain relief, maximal analgesic effect, SPID, TOTPAR values, adjusted mean number of observations with pain at least half-relieved, and the final overall evaluation records were all superior for piroxicam-FDDF (p < 0.05). The results of this study clearly show that the analgesic efficacy of piroxicam-FDDF is superior to naproxen sodium in the treatment of pain following oral surgery for the removal of impacted third molars.

OBJECTIVES: Two composite outcome measures were used to assess the efficacy of work-site risk factor interventions: the Framingham multiple logistic function and a standardized composite equation that was an unweighted combination of risk factors. METHODS: Twenty-eight work sites in Sydney, Australia, were randomly assigned to health risk assessment, risk factor education, behavioral counseling, or behavioral counseling plus incentives. RESULTS: Over 12 months, scores on the multiple logistic function increased for the behavioral counseling plus incentives condition relative to the other conditions. Standardized scores decreased for behavioral counseling relative to the incentive condition and the average of all other conditions. CONCLUSIONS: Behavioral counseling produces larger changes in the life-style behaviors contributing to coronary heart disease risk than other commonly used interventions.

OBJECTIVES: Receptionists are an integral part of the primary care service. We aimed to discover their views on preventive medicine issues. METHOD: One hundred and fifty receptionists from general practices in Sydney, Australia, completed a questionnaire on their attitudes and beliefs towards preventive medicine and brief intervention for alcohol. They were matched according to practice variables into a control, no, minimal, or maximal training and support condition. In all conditions except the control condition, receptionists received 5 minutes of initial training in implementing a brief intervention programme; the amount of ongoing support varied across conditions. Attitudes and beliefs were re-assessed 3 months later. RESULTS AND CONCLUSIONS: The results indicated that when no training and support were given, receptionists developed negative views towards being involved in preventive medicine activities. When training and support were provided, these negative effects were abolished.

The search for new effective analgesics without unwanted effects on the coagulation mechanism and a longer duration of activity has been intensified. One such development is diflunisal and the aim of this study was to compare the analgesic effect of diflunisal with that of paracetamol. A combined single dose (500-mg tablets), double-blind, randomized, controlled design in out-patients (n = 104) with moderate or severe pain caused by the surgical removal of impacted mandibular third molars was used in this study. Pain intensity and relief were assessed postoperatively for 8h using category-rating scales. The results showed a statistically significant difference in favour of diflunisal in each and every parameter used in determining the efficacy of the treatment.

We used outcome data from a randomized work site intervention trial to examine the cost-effectiveness of four cardiovascular disease (CVD) risk reduction programs: health risk assessment (HRA), risk factor education (RFE), behavioral counseling (BC), and behavioral counseling plus incentives (BCI). Composite CVD risk scores were derived from measures of serum total cholesterol, blood pressure, number of cigarettes smoked, body mass index, and aerobic capacity. The economic evaluation of the programs focused on the subset of costs most sensitive to the differences between the interventions, and a sensitivity analysis examined some of the relevant cost variations. At the 6-month follow-up (i.e., the "action" or initiation stage of lifestyle change), the RFE, BC, and BCI interventions produced a significant reduction in cardiovascular risk. Incremental analyses demonstrated RFE to be more cost-effective, but not as clinically effective as BC; BC was more cost-effective than RFE when assessment costs were included, and BCI was judged to be the least cost-effective. At the 12-month follow-up (i.e., the "maintenance" stage of lifestyle of change), BC was the only program found to produce a significant reduction in CVD risk. Individualized behavioral counseling was found to be a cost-effective strategy for the initiation and maintenance of CVD risk factor reduction.

In April 1990, the Argentine Group for Treatment of Acute Leukemia began a multicenter trial for the treatment of previously untreated acute myeloblastic leukemia patients who were under 21 years of age. Initial treatment consisted of an 8-day induction phase with cytarabine together with idarubicin on days 3 to 5 and etoposide on days 6 to 8. A multidrug consolidation phase was subsequently administered and, after a treatment-free interval of 2 to 4 weeks, two 5-day intensification courses with high-dose cytarabine and etoposide were delivered with a 4-week interval between each course. Continuation therapy was started 2 to 4 weeks after the second course, with 6-thioguanine daily and cytarabine daily for 4 days every 4 weeks. Treatment was stopped after 18 months in children in continuous complete remission. A preliminary evaluation of this ongoing study included 36 patients with a mean age of 7.5 years (age range, 5 months to 16 years). The majority of patients had a French-American-British classification of M2 (n = 13) or M4 (n = 8). Complete remission was achieved by 91.7% of patients, while one died from sepsis in bone marrow hypoplasia and two were regarded as treatment failures. At a median follow-up of 12 months (range, 2 to 23 months) there were 12 adverse events: six bone marrow relapses, one bone marrow/skin relapse, and five deaths in complete remission (all deaths occurred during the consolidation phase). During the induction phase most of the patients experienced prolonged myelosuppression, and grade 3 to 4 toxicity (according to the Children's Cancer Group criteria) was frequently seen. Alopecia was universal. However, toxicity was manageable. We conclude that idarubicin in combination with cytarabine and etoposide is a highly effective regimen for induction in children with acute myeloblastic leukemia.

OBJECTIVES: This study reports an efficacy trial of four work-site health promotion programs. It was predicted that strategies making use of behavioral counseling would produce a greater reduction in cardiovascular disease risk factors than screening and educational strategies. METHODS: Twenty-eight work sites were randomly allocated to a health risk assessment, risk factor education, behavioral counseling, or behavioral counseling plus incentives intervention. Participants were assessed before the intervention and at 3, 6, and 12 months. RESULTS: Compared with the average of the health risk assessment and risk factor education conditions, there were significantly higher validated continuous smoking cessation rates and smaller increases in body mass index and estimated percentage of body fat in the two behavioral counseling conditions. The behavioral counseling condition was associated with a greater reduction in mean blood pressure than was the behavioral counseling plus incentives condition. On average among all groups, there was a short-term increase in aerobic capacity followed by a return to baseline levels. CONCLUSIONS: Work-site interventions that use behavioral approaches can produce lasting changes in some cardiovascular risk factors and, if implemented routinely, can have a significant public health impact.

Changes in patients' lifestyles can be approached in a practical fashion by working through the relevant 'stages of change'. Helping patients to change their lifestyles does not have to be a very time-consuming process for the clinician, but it does require planning, and attention to those factors that are important at each stage of the process. Although this paper has a focus on lifestyle change for the reduction of CVD risk factors, the same principles can apply to lifestyle change and disease prevention for other disorders.

Lifestyle change is an area in which the medical practitioner has a great deal to offer: to high-risk patients and to individuals generally. The evidence supporting the cardiovascular health benefits of lifestyle change comes from a variety of scientific sources. While the recent large-scale intervention studies have not always had unequivocal outcomes, on balance, the epidemiological evidence points to the central importance of lifestyle change in reducing CVD risk. Recently the United States Preventive Services Task Force22 has published guidelines on lifestyle change and other interventions for CVD risk and for a range of other preventable health problems. The United States Task Force's recommendations have been favourably reviewed by the National Health and Medical Research Council in Australia, and are considered to be relevant to medical practice in this country.

A large amount of observational and experimental research has demonstrated that lifestyle factors are important determinants of cardiovascular disease. In particular, epidemiological evidence from large, controlled multiple risk factor intervention trials and research examining the effects of secular changes in lifestyle on changing morbidity and mortality rates indicate that changes in lifestyle can reduce the risk of coronary heart disease (CHD). This paper provides an overview of the lifestyle change process and provides guidelines for increasing the efficacy of lifestyle change interventions in clinical settings.

A variety of approaches have been used to reduce Cardiovascular Disease (CVD) risk in the community, including programs based in the workplace. To date, it has been difficult to draw accurate conclusions on the effectiveness of worksite CVD risk reduction programs. Typically, such programs suffer from poor participation and high attrition rates and most lack physical and biochemical validation of self-reported lifestyle changes. The present paper describes an evaluation of four health promotion worksite interventions (screening, education, incentive and lifestyle change) conducted in the NSW Ambulance Service. The study achieved very high participation and low attrition rates. Self-reported changes in lifestyle were validated with physical and biochemical measures. The results suggest greater change in some risk factors for those individuals receiving the incentive and lifestyle change programs compared to screening alone or education.
