Case Reports Comparative Study
[Patellar metastasis of colon carcinoma. A rarity in differential diagnosis of acute knee pain. Case report].
Although bone tumors are often located in the knee area, primary tumors of the patella are rare, and patellar metastases extremely rare. Only a few cases were reported in the literature originating from different primary tumors, mostly lung and breast [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 18, 19, 20, 22]. ⋯ We present a rare case of primary sigma carcinoma and patellar metastasis. Because of the increasing rate of colon carcinomas, neoplastic disease must be considered in the differential diagnosis in any patient with otherwise unexplained knee pain.

Comparative Study
[Current situation of traffic accidents in children and adolescents. A medical and technical analysis].
Analysis of the current injury situation in road users not exceeding 14 years of age involved in road traffic accidents to allow conclusions regarding future prophylaxis. ⋯ Children have an especially high risk of injury if they are involved in accidents as pedestrians, bicyclists and unrestrained car occupants. Besides of improvements of the inner and outer car design, the use of adjusted restraining systems and bicycle helmets is likely to prevent from severe injuries. Speed reduction is a considerable factor. According to our data, the injury severity for bicyclists and pedestrians increases progressively when the collision speed exceeds 50 km/h.
