The chemicals between us-First results of the cluster analyses on anatomy embalming procedures in the German-speaking countries

Hands-on courses utilizing preserved human tissues for educational training offer an important pathway to acquire basic anatomical knowledge. Owing to the reevaluation of formaldehyde limits by the European Commission, a joint approach was chosen by the German-speaking anatomies in Europe (Germany, Austria, Switzerland) to find commonalities among embalming protocols and infrastructure. A survey comprising 537 items was circulated to all anatomies in German-speaking Europe. Clusters were established for "ethanol"-, formaldehyde-based ("FA"), and "other" embalming procedures, depending on the chemicals considered the most relevant for each protocol. The logistical framework, volumes of chemicals, and infrastructure were found to be highly diverse between the groups and protocols. Formaldehyde quantities deployed per annum were three-fold higher in the "FA" (223 L/a) compared to the "ethanol" (71.0 L/a) group, but not for "other" (97.8 L/a), though the volumes injected per body were similar. "FA" was strongly related to table-borne air ventilation and total fixative volumes ≤1000 L. "Ethanol" was strongly related to total fixative volumes >1000 L, ceiling- and floor-borne air ventilation, and explosion-proof facilities. Air ventilation was found to be installed symmetrically in the mortuary and dissection facilities. Certain predictors exist for the interplay between the embalming used in a given infrastructure and technical measures. The here-established cluster analysis may serve as decision supportive tool when considering altering embalming protocols or establishing joint protocols between institutions, following a best practice approach to cater toward best-suited tissue characteristics for educational purposes, while simultaneously addressing future demands on exposure limits.

The effect of skin surface topography and skin colouration cues on perception of male facial age, health and attractiveness

OBJECTIVE

Previous studies investigating the effects of skin surface topography and colouration cues on the perception of female faces reported a differential weighting for the perception of skin topography and colour evenness, where topography was a stronger visual cue for the perception of age, whereas skin colour evenness was a stronger visual cue for the perception of health. We extend these findings in a study of the effect of skin surface topography and colour evenness cues on the perceptions of facial age, health and attractiveness in males.

METHODS

Facial images of six men (aged 40 to 70 years), selected for co-expression of lines/wrinkles and discolouration, were manipulated digitally to create eight stimuli, namely, separate removal of these two features (a) on the forehead, (b) in the periorbital area, (c) on the cheeks and (d) across the entire face. Omnibus (within-face) pairwise combinations, including the original (unmodified) face, were presented to a total of 240 male and female judges, who selected the face they considered younger, healthier and more attractive.

RESULTS

Significant effects were detected for facial image choice, in response to skin feature manipulation. The combined removal of skin surface topography resulted in younger age perception compared with that seen with the removal of skin colouration cues, whereas the opposite pattern was found for health preference. No difference was detected for the perception of attractiveness. These perceptual effects were seen particularly on the forehead and cheeks. Removing skin topography cues (but not discolouration) in the periorbital area resulted in higher preferences for all three attributes.

CONCLUSION

Skin surface topography and colouration cues affect the perception of age, health and attractiveness in men's faces. The combined removal of these features on the forehead, cheeks and in the periorbital area results in the most positive assessments.

Gesundheitsbezogene Lebensqualität von Geschwistern an Diabetes mellitus Typ 1 erkrankter Kinder und Jugendlicher

BACKGROUND INFORMATION

A chronic illness in childhood or adolescents constitutes a drastic event for the whole family, especially for the healthy siblings. This could impair their quality of life.

PATIENTS AND METHODS

We designed a case-control-study in three centres (Leipzig, Giessen and Augsburg) with questionaires sent to 72 diabetic children, 71 of their siblings and 63 children of neighbourhood (controls) aged between 8 and 16 years. KINDL-Questionnaire was used for the study of the health-related quality of life of children and adolescents, supplemented by other appropriate items.

RESULTS

The results indicate a positive health related quality of life of the healthy siblings of families with a child who has type 1 diabetes. Differences in the quality of life depend on factors such as age and gender of the children and relate to specific items of sibling relationship (e. g. "worried about sibling", "looked after sibling"). Generally, there was a great similarity with regard to the quality of life of healthy brothers and sisters from affected families compared with children of families without a child suffering from chronic illness.

CONCLUSIONS

The results indicate that the health related quality of life of healthy siblings of children with diabetes only differs insignificantly from brothers and sisters of "healthy" families.
