A retrospective study was carried out on all motorcycle injuries occurring at Mondelo Park racetrack for the 1983 and 1984 seasons. In this sport there were a total of 57 injuries for the two year period, 27 occurring in 1983 and 30 in 1984. Soft tissue injuries accounted for 66.7%, fractures 22.8% and head injuries 10.5% of the total. In the fracture group, 2 patients suffered spinal fractures...

End-point correction " Performance pay jobs " are defined as jobs that have paid for performance at least once in the past. Thus, job matches that are observed over a longer period are more likely to be observed as PP jobs. For this reason, job matches that are observed at the beginning of the observation period in 1984 may be misclassified as non-PP jobs if they paid for performance before 198...

Background and Objective: Malignant otitis externa is a rare but potentially fatal infection. It tends to affect the elderly as well as patients with diabetes and immunocompromised status. We aimed to identify the epidemiological, clinical, therapeutic, and evolutionary features of malignant otitis externa. Methods: We conducted a retrospective study including patients hospitalized in the infe...

Welfare states redistribute both between individuals (inter-individual redistribution) reducing annual, cross-sectional inequality and over the lifecycle of an individual (intra-individual redistribution) insuring individuals against income risks in the long-term. But studies measuring redistribution often focus on a one-year period and the second aspect is neglected. To quantify both interand ...

The incidence of traffic injuries was studied during a two year period from 1983 to 1984 using routinely collected statistics by the Traffic Police. The severity of injuries was analysed by age and sex in different categories of road users. Causes leading to the occurrence of accidents were also examined in pedestrian victims. An annual incidence of 11,253 injuries for 1983 and 11,856 for 1984 ...

Sprinting with a lower-limb amputation over 100 m has taken place in the Paralympic Games for over three decades. The aim of this paper is to statistically evaluate the performances and participation levels of such athletes during this period. The level of performance improvement over a 36-year period was proposed to be significantly greater than the able-bodied equivalent. Coupled with this, a...

During an 11-year period (1978 to 1989), over 300 strains of Yersinia spp. (excluding Y. pestis and Y. pseudotuberculosis) were recovered from a variety of gastrointestinal and extraintestinal sites in patients in California. Over the 11-year period, Y. enterocolitica serogroup O:3 predominated, although a shift in the relative frequency of this serogroup was observed during this interval, incr...

This study introduces the monitoring system to be established within this project, it aims to determine changes occurring within forested areas, settlement areas and other land use forms located at the peripheral area of Istanbul during consecutive decades. The first phase of the study was completed in 1998 and published, covering the period from 1984 to 1994. This study is the second phase of ...

The serotypes and susceptibilities to penicillin, macrolides, and clindamycin of 1,655 invasive isolates of Streptococcus pneumoniae recovered between 1979 and 2004 were determined. A precipitous decrease of 61% in the number of isolates was found following 2000, the year of 7-valent protein-conjugated pneumococcal vaccine (PCV7) introduction (139 versus 55 per 2-year period prior to versus aft...
