Cervical hip fracture in a Finnish population: incidence and mortality.

BACKGROUND AND AIMS: Our aim was to describe the incidence of cervical hip fractures and to describe the relationships between selected background variables and mortality at 30 days, 6 months, and 3 years postoperatively. MATERIAL AND METHODS: The basic material consisted of population-based data set of patients aged 65 years or older who had sustained a hip fracture and were treated operatively between 1999 and 2000. Out of these, we identified 266 consecutive patients with cervical hip fracture. RESULTS: The age-adjusted incidence of cervical hip fractures in women was 1.3-fold compared to men. In age-adjusted analysis, occurrence of chronic lung disease, cardiovascular disease or 2-5 comorbidities, male gender, the need for 2-person mobility assistance, and poor ambulation postoperatively were associated with excess mortality at least at one evaluation point. CONCLUSIONS: Only chronic lung disease and male gender were independent predictors of increased mortality at each follow-up assessment in multivariate analysis.

The impact of proximal femur geometry on fracture type--a comparison between cervical and trochanteric fractures with two parameters.

INTRODUCTION: Only a few studies have tested the ability of proximal femur geometry parameters to discriminate between cervical hip fractures and those of the trochanter. The main objective of this study was to evaluate the geometrical differences between these two fracture types by measuring the neck shaft angle (NSA) and the femoral neck axis length (FNAL). We also compared the distributions of these parameters and the distributions of fracture type by gender. MATERIAL AND METHODS: A retrospective analysis was made in a population-based material of 428 hip fractures collected during a two-year period from 1999 to 2000 (323 women and 105 men aged 65 years or older). NSA and FNAL were manually measured from pelvic radiographs. RESULTS: No significant differences in NSA or FNAL were found between cervical and trochanteric hip fractures in women or in men. Men had significantly higher NSA and FNAL than women. Age was not related to these geometrical parameters. The distributions by fracture type were similar in both genders. CONCLUSIONS: The different pathogenesis of cervical and trochanteric hip fractures cannot be explained by NSA or FNAL. A standardized measurement setup is needed when evaluating the role of hip geometry in fracture patients.

Mortality and air pollution in Helsinki.

In Helsinki, Finland, from 1987 to 1993, the authors studied the associations between daily concentrations of sulphur dioxide, nitrogen dioxide, ozone, total suspended particulates, and particulates with aerodynamic diameters less than 10 microm (PM10), and the daily number of deaths from all causes and from cardiovascular causes. Investigators used Poisson regressions to conduct analyses in two age groups, and they controlled for temperature, relative humidity, day of the week, month, year, long-term trend, holidays, and influenza epidemics. The PM10 levels were associated significantly with all-cause and cardiovascular mortality among persons under the age of 65 y of age. In the less-than-65-y age group, sulfur dioxide and ozone were also associated significantly with cardiovascular mortality. The effect of ozone was independent of the PM10 effect, whereas sulfur dioxide became nonsignificant when modeled with PM10. An increase of 10 microg/m3 in PM10 resulted in increases in total mortality and cardiovascular mortality of 3.5% (95% confidence interval=1.0, 5.8) and 4.1% (95% confidence interval=0.4, 10.3), respectively. A 20 microg/m3 increase in ozone was associated with a 9.9% (95% confidence interval=1.1, 19.5) increase in cardiovascular mortality; however, ozone results were inconsistent. Moreover, in addition to their separate effects, high concentrations of PM10, ozone, and nitrogen dioxide had a further harmful additive effect. Typically, PM10 was a better indicator of particulate pollution than total suspended particulates. The authors' findings suggest that (a) even low levels of particulates are related to an increase in cardiovascular mortality; (b) ozone--even in low concentrations--is associated, independently, with cardiovascular mortality; and (c) PM10, ozone, and nitrogen dioxide--the essential components of summertime pollution--have harmful interactions at high concentrations.

[Enterococcal endocarditis following legal abortion]. / Enterokochendokardit efter legal abort.

PIP: Uterine infections after early legal abortion are not very frequent and are most often connected with remaining embryonic material. In the case described, a 42-year old woman with 2 normal deliveries, 1 spontaneous abortion, and 2 legal abortions, who earlier had salpingitis, sought legal abortion in the 1st trimester. A vacuum aspiration was carried out in week 9-10 with no complications. Fever appeared on the 1st postoperative day and reached 40 degrees Celsius. Treatment was begun with doxycycline and metronidazole for 7 days and methyl ergometrine for 3 days. The patient improved but returned with fever again 2 months after the operation. Culture showed enterococci and pelvic examination showed regressively altered placental tissue. 5 months after the primary event the patient was again admitted with high fever, exhaustion and cardiac arrhythmia with aortal and mitral insufficiency. Computer tomography showed a soft swelling containing gas bubbles along the west wall of the vagina. The patient was operated on for hysterectomy and bilateral salpingo-oophorectomy. A year after the abortion the patient received an implanted aorta and mitral valve. A year after the valve operation the patient showed no signs of further infection. Pregnancy over age 40 implies increased risk for septic complications; retained abortion material with chronic endometritis and subsequent parametritis imply that antibiotic treatment will be unsuccessful until the focus of infection is removed surgically.^ieng
