Abstract

Purpose

Proper handwashing helps prevent the spread of communicable diseases. The aim of our study was to analyse and compare children's knowledge and skills in hand hygiene before and after school interventions in order to evaluate the effectiveness of our peer education programme.

Materials/methods

In our longitudinal study, short- and long-term changes in the knowledge, hand-washing skills and health behaviour of 224 lower, upper and secondary school students were assessed. Our measurements were performed with a self-administered, anonymous questionnaire and the Semmelweis Scanner.

Results

As a result of the intervention, the proportion of correct answers increased significantly both in the short term and in the long run compared to the input measurements, but age differences did not disappear for most variables. There is a difference in the process of learning theoretical knowledge and practical skills. Areas not used for handwashing in the paediatric population are different from those described for adults in the literature. There was no significant difference between the mean scores of the right and left hands.

Conclusions

There was a significant positive change in both theory and practice of handwashing. In education, emphasis should also be put on long-term retention of theoretical knowledge in age-specific health promotion programmes within the paediatric population.

Six pieces of grafts, 6.5 mm in diameter, 20 mm in length, were taken from each of 170 cadaver hindlimbs, using the cranial surface of the medial femoral trochlea for harvesting. The age of the horses varied between 4 months and 23 years. 30 limbs under the age of 12 years were selected for transplantation. Three of six grafts were transplanted into the medial femoral condyle using different combinations of tunnel depth and dilation. With ageing, a significant decline in transplantability was detected. In general, mosaicplasty cannot be recommended in horses above 11 years. Based on a previous clinical case (Bodo et al., 2000), a good surface alignment was indeed achieved with a combination of graft length drilling and dilation in most cases. However, the occasional entrapment of cartilage debris under the graft prevented perfect alignment in the present cadaver study in 27% of the grafts transplanted in this manner. Since the protrusion of grafts never exceeded 1.5 mm, we conclude that drilling 3–5 mm deeper than graft length with graft length deep dilation can avoid disadvantageous protrusion of the transplanted hyaline cartilage caps, achieving bone decompression at the same time.
