[Comparative study of clinical effectiveness of antibiotic prophylaxis in aseptic mouth-jaw- and facial surgery].

METHODS: This study evaluates the clinical efficiency of four regimens of antibiotic prophylaxis against wound infection in aseptic oral and maxillofacial surgery that does not involve implantation of foreign material and included 140 adult patients randomly distributed into four groups. Patients from two groups received prophylactic amoxicillin/clavulanate in a single-dose regimen or a 5-day regimen, respectively. Subjects from the other two groups received cefazolin in a single-dose regimen or a 5-day regimen, respectively. RESULTS: Clinical prophylactic efficiency proved to be equal for the four types of antibiotic regimens. DISCUSSION: Single-dose regimens are more economical, easier to administer, and carry a lower risk of inducing bacterial resistance. Amoxicillin/clavulanate is more expensive than cefazolin. For aseptic maxillofacial surgery that does not involve implantation of foreign material, we recommend preoperative single-dose antibiotic prophylaxis with cefazolin 2 g i.v. (in adult patients).

A prospective study of the effect of fracture on measured physical performance: results from the MacArthur Study--MAC.

OBJECTIVE: To examine the impact of fractures on measured physical performance and to assess whether specific fractures have unique sequelae. SUBJECTS: 762 men and women, aged 70 to 79 at baseline, who were part of the MacArthur Study of Successful Aging. DESIGN: A longitudinal case-cohort: those with prevalent fractures at baseline were excluded; cases were persons with a medically diagnosed hip, arm, spine, or wrist fracture during the follow-up period (1988-1995). MEASURES: Eight physical performance tests: turning a circle, walking fast, chair stands, timed tap, tandem stand, grip strength, single leg stand, and balance (average of single leg and tandem stands) measured at baseline and follow-up. ANALYSIS: Two fracture groups were defined: (1) those with incident wrist fractures (n = 7) and (2) those with a fracture of the hip, arm, or spine (combined fractures group, n = 16). Change in physical performance was analyzed using crude, age-adjusted, and multiply-adjusted ANCOVA models. RESULTS: The combined fracture group demonstrated statistically significant (P < .05) declines seven of eight of the performance tests compared with individuals without fractures. In contrast, individuals with wrist fractures did not experience a statistically significant decline in any performance measure compared with the no fracture group. CONCLUSIONS: Relative to those without fractures, individuals with a hip, arm, or clinical spinal fracture show similar global declines in physical performance, whereas those with wrist fracture demonstrate no physical performance decrements.

Eight years of experience in the first Romanian center of family planning and contraception.

This study describes 8 years of experience (1990-97) in the first Romanian center for family planning and contraception, which started in Bucharest at the Clinic Hospital of Obstetrics and Gynecology 'Prof. Dr. P. Sirbu' on 27 February 1990. A total of 14,258 women had attended the clinic by 1 January 1998. Trends in the use of contraceptives and the number of births and abortions at the center are described. During the 8 years, the induced abortions decreased by 65% and the uncompleted abortions (illegal abortions) by 45%. Hormonal contraception was the most commonly used contraceptive method (61.5%), followed by intrauterine devices (28.8%) and local contraception (barrier methods: condoms, diaphragms, spermicides) (9%).
