Modified IOTN: an orthodontic treatment need index for use in oral health surveys.

This paper reports the results of a study of the reliability of a modified version of the Index of Orthodontic Treatment Need (IOTN) for use in oral health surveys. Twelve non-specialist dental examiners were trained in the use of the Modified IOTN using a standardised teaching protocol lasting approximately 1.5 hours. Following a school-based calibration exercise it was found that nearly all the examiners achieved either good or excellent agreement (mean Kappa=0.74). The average sensitivity and specificity scores were 0.90 and 0.84, respectively. The Modified IOTN appears to overcome the training and reliability problems that often accompany the use of orthodontic indices by non-specialists in oral health surveys.

An intervention programme to establish regular toothbrushing: understanding parents' beliefs and motivating children.

AIMS/OBJECTIVES: To determine the benefit of twice daily toothbrushing on newly erupted first permanent molars. To investigate, through the Health Belief Model, how parents' beliefs influence the likelihood of their children brushing twice a day. To identify aspects of a toothbrushing intervention programme that can be used in general dental practice. DESIGN: Randomised controlled trial. SETTING: Schools in deprived communities in Scotland. PARTICIPANTS: 461, 5-year-old children. INTERVENTIONS/METHODS: Supervised toothbrushing on school-days with a 1,000 ppm chalk-based fluoride toothpaste for two years. A school and home-based incentive scheme including toothbrushing charts, 6-monthly dental examinations and parental questionnaires. MAIN OUTCOME MEASURES: Caries increment and twice daily toothbrushing. RESULTS: In the control group, children who brushed once a day or less had 64% more caries than those who brushed at least twice a day (P = 0.001). In the intervention group this difference in caries was reduced to 16% (P > 0.05). The most significant parental belief explaining variation in twice-daily brushing was whether parents feel strongly that there is time to check their child's toothbrushing (P = 0.0001). The odds of these parents reporting that their child brushes twice daily are nearly three times greater. 95% of parents felt that toothbrushing charts would be a good way for dentists in practice to encourage children to brush regularly. CONCLUSIONS: The benefit of twice daily toothbrushing on caries development in newly erupted first permanent molar teeth is around 50% compared to brushing once a day or less. Parents' beliefs do influence the likelihood of their children brushing twice a day. Key parts of the intervention programme can be used when children attend general dental practice and would be welcomed by parents.

"Doing" diversity. Holy Cross Health System facilities honor differences in different ways.

Holy Cross Health System (HCHS), a South Bend, IN-based organization that stretches from coast to coast, has instituted a diversity initiative to take advantage of demographic changes in its facilities' work forces and the communities they are serving. Launched by Holy Cross's corporate headquarters, the program is carried out by the member facilities, each of which had added its own ideas. HCHS's diversity program has three major components: Consciousness-raising among employees. Activities range from "transcultural rounds" for nursing students to fashion shows in which employees wear costumes from their places of national origin. Educating the larger community. HCHS facilities have been urged to increase awareness of diversity among physicians, patients, vendors, and local business and civic leaders. Strategic thinking. The leaders of HCHS facilities have been advised to integrate diversity into their strategic planning. Leaders are familiarizing themselves with the different cultural, ethnic, and religious groups in the community and preparing their facilities to take full advantage of those groups' contributions.

Melphalan concentration and distribution in the tissues of tumour-bearing limbs treated by isolated limb perfusion.

Levels of melphalan (L-phenylalanine mustard) were measured in the tissues of tumour-bearing limbs treated by isolated limb perfusion (ILP). 41 samples of melanoma tissue, normal fat and skin were excised from 15 patients during ILP. A high performance liquid chromatography assay was used to measure melphalan concentrations. Levels of melphalan were higher in tumour than in fat (P < 0.01, Wilcoxon signed-ranks test), and not significantly different from levels in adjacent skin. In 2 cases there was significant regional toxicity in the treated limb, but this was not related to the levels of melphalan measured in the tissues of the limb. It is encouraging that the concentrations of melphalan which were achieved in large necrotic nodules by ILP were similar to those in well-perfused normal skin.

The pharmacokinetic advantages of isolated limb perfusion with melphalan for malignant melanoma.

We describe melphalan pharmacokinetics in 26 patients treated by isolated limb perfusion (ILP). Group A (n = 11) were treated with a bolus of melphalan (1.5 mg kg-1), and in a phase I study the dose was increased to 1.75 mg kg-1. The higher dose was given as a bolus to Group B (n = 9), and by divided dose to Group C (n = 6). Using high performance liquid chromatography (HPLC) the concentrations of melphalan in the arterial and venous perfusate (during ILP) and in the systemic circulation (during and after ILP) were measured. Areas under the concentration time curves for perfusate (AUCa, AUCv) and systemic (AUCs) data were calculated. In all three groups the peak concentrations of melphalan were much higher in the perfusate than in the systemic circulation. The pharmacokinetic advantages of ILP can be quantified by the ratio of AUCa/AUCs, median value 37.8 (2.1-131). AUCa and AUCv were both significantly greater in Group B than in Group A (P values less than 0.01, Mann-Whitney). In Groups B and C acceptable 'toxic' reactions occurred but were not simply related to melphalan levels. Our phase I study has allowed us to increase the dose of melphalan to 1.75 mg kg-1, but we found no pharmacokinetic advantage from divided dose administration.

Cancer at the workplace: health promotion and care programs.

The "Europe Against Cancer" initiative seeks to reduce the prevalence of cancer by 15% by the year 2000. This has stimulated an increased awareness of cancer by health care professionals. A training manual was designed to provide opportunities for workplace health care professionals in Northern Ireland to make an impact in the area of prevention and early detection of cancer. The training manual examines attitudes and knowledge about cancer and discusses relevant, effective programs for the prevention and early detection of cancer. It also seeks to enable the development of care and rehabilitation support programs in the workplace. The process of developing the training manual involving occupational health and health education staff is considered to be part of its success.

A randomised controlled trial of the efficacy of supervised toothbrushing in high-caries-risk children.

Scottish children have one of the highest levels of caries experience in Europe. Only 33% of 5-year-old children in Dundee who developed caries in their first permanent molars by 7 brushed their teeth twice a day. High-caries-risk children should benefit if they brush more often with fluoridated toothpaste. The aim of this clinical trial was to determine the reduction in 2-year caries increment that can be achieved by daily supervised toothbrushing on school-days with a toothpaste containing 1,000 ppm fluoride (as sodium monofluorophosphate) and 0.13% calcium glycerophosphate, combined with recommended daily home use, compared to a control group involving no intervention other than 6-monthly clinical examinations. Five hundred and thirty-four children, mean age 5.3, in schools in deprived areas of Tayside were recruited. Each school had two parallel classes, one randomly selected to be the brushing class and the other, the control. Local mothers were trained as toothbrushing supervisors. Children brushed on school-days and received home supplies. A single examiner undertook 6-monthly examinations recording plaque, caries (D(1) level), and used FOTI to supplement the visual caries examination. For children in the brushing classes, the 2-year mean caries increment on first permanent molars was 0.81 at D(1) and 0.21 at D(3) compared to 1.19 and 0.48 for children in the control classes (significant reductions of 32% at D(1) and 56% at D(3)). In conclusion, high-caries-risk children have been shown to have significantly less caries after participating in a supervised toothbrushing programme with a fluoridated toothpaste.
