Age can be considered among influential factors. Aim of the Study: To compare mandibular fractures between children and adults from the beginning up to the treatment in Senegal. Patients and Method: A three-year retrospective study was conducted in a university hospital. The medical records of patients admitted for maxillofacial injuries were reviewed. Patient and injury-related variables including age, gender, etiology, average consultation delay, anatomic location of fracture and treatment were compared up to age of 15 and beyond that. Results: Considering 272 casualties, maxillofacial fractures were less frequent among children than adults (36.7% and 59.7%) and were mainly mandibular (90.1% and 91.4%). Male predilection (sex ratio of 2.4 and 4.9) was twice (2) as pronounced from the age of 16. The average consultation delay was two (2) times shorter for children. Road traffic accidents which predominated among children (33.9%) had comparable frequency (32.3%) although they were outnumbered by assault (37.6%) among adults. Fractures occurred mainly on the corpus (90.1% and 90.4%), particularly on parasymphysis (40.1%) up to the age of 15, whereas angle fractures increased (8.5% to 19.6%) and joint damage decreased afterwards. Intra-oral orthopedic procedures (91.2% and 92.6%) in which mandibular retention splints were more common (37.3%) up to the age of 15 then arch ligatures (49%) were then widely favored. Conclusion: Differences relating to the distribution of causes but also to the anatomic location on the corpus and to the choice of intra-oral orthopedic procedures within overall similarities between children and adults regarding the male predilection, the frequency of road traffic accidents, the mandibular injuries, but also the school therapeutic attitude consisting of favoring the orthopedic option.展开更多

Older parents are at risk of having to accompany their adult children through a severe illness, sometimes even to their death. The present study investigates the experiences of being a parent to an adult child with a severe illness and what support was helpful during the child＇s period of illness. Method： A qualitative approach with in-depth interviews which were analyzed using content analysis. Results： The results showed that a common perception was that it is very special to have a child with a severe illness. The underlying elements of existential experience and the relationship both influenced the parents＇ conceptions of life and permeated the whole situation. There were four areas that the parents found important and influenced how they could manage the situation： having information, participation, strategies to cope with the situation, and support. Conclusions： Accompanying an adult child through a severe and potentially fatal disease in the context of a growing elderly population will become an increasingly frequent problem. So far there is limited research in this area and more research should be a high priority in the future.展开更多

METHODS： Patients with CD who were seen in 2001- 2003 in the University of Malaya Medical Centre （UMMC） were enrolled in this study. Prevalence of disease was calculated for the group as a whole and by race with hospital admissions per ethnic group as the denominator. RESULTS： Thirty-four patients were diagnosed to have CD. Basic demographic data of patients; male：female 17：17; mean age 29.1 years （±13.5 years）; ethnic group： Malays 5 （14.7%）, Chinese 12 （35.3%） and Indians 17 （50%）. Twenty-six （76.5%） were diagnosed under the age of 40 and 8 （23.5%） were diagnosed over the age of 40. Location of the disease was as follows： ileocolonic 13 （38.2%）, terminal ileum only 9 （26.5%）, colon only 8 （23.5%）, and upper gastrointestinal 4 （11.8%）. Sixteen （47.1%） had penetrating disease, 9 （26.5%） had stricturing disease and 9 （26.5%） had nonpenetrating and non-stricturing disease. The hospital admission prevalence of CD was 26.0 overall, Indians 52.6, Chinese 6.9, and Malays 9.3 per 10^5 admissions per ethnic group. The difference between Indians and Malays： [OR 5.67 （1.97, 17.53）P〈 0.001] was statistically significant but not between the Indians and the Chinese [OR 1.95 （0.89, 4.35） P= 0.700]. The difference between the Chinese and the Malays was also not statistically significant. [OR 2.90 （0.95, 9.42）P= 0.063]. CONCLUSION： The clinical presentation of CD is similar to the Western experience. Although the overall prevalence is low, there appears to be a clear racial predominance among the Indians.展开更多
