Cefotetan therapy for gonococcal urethritis and cervicitis.

The authors compared the safety and efficacy of 0.5 and 1.0 g of cefotetan with that of 0.25 g of ceftriaxone in a 3:3:2 randomized distribution. Of 172 patients (96 men, 76 women) aged 18-43 years who were being treated at the Delgado Venereal Disease Clinic, New Orleans Health Department, for acute gonococcal urethritis or cervicitis, 123 were evaluable (81 men, 42 women). All men and 16 women were initially symptomatic. All were culture positive for Neisseria gonorrhoeae. At the 4-8 day follow-up, cultures were negative for N. gonorrhoeae in all except one man and one woman, each of whom received cefotetan 0.5 g. Symptoms were eliminated 12-72 hr after therapy in all groups. Cefotetan was well tolerated, and there were few adverse experiences reported. Thus, the authors consider cefotetan safe and effective for the treatment of uncomplicated gonorrhea.

Quantitative assessment and training of isometric cervical extension strength.

The purpose of this study was to evaluate the reliability and variability of repeated measurements of isometric cervical extension strength and determine the effect of 10 weeks of dynamic variable resistance cervical extension training on isometric cervical extension strength. Seventy-three subjects (age, 29 +/- 12 years [mean +/- SD]) completed isometric cervical extension strength tests on 4 separate days (D1, D2, D3, and D4). For each test, isometric cervical strength was measured at 126 degrees, 108 degrees, 90 degrees, 72 degrees, 54 degrees, 36 degrees, 18 degrees, and 0 degrees of cervical flexion. Between-day correlation coefficients over the eight angles of cervical flexion were high for D2 versus D3 (r = 0.90 to 0.96). Test variability (standard error of estimate) between D2 versus D3 was low (7.4% to 10.2% of mean) through the entire range of motion. Regression analysis showed that the isometric cervical extension strength curve is linear and descending from flexion to extension. In a second study, 14 subjects (age, 25 +/- 3 years) trained the cervical extensor muscles for 10 weeks while 10 subjects (age, 23 +/- 3 years) served as controls. Training included 8 to 12 cervical extensions to volitional fatigue, 1 day per week. The training group improved isometric cervical extension strength at six of eight angles before to after training (P less than or equal to 0.05). During the same time period the control group did not change. These data indicate that repeated measures of isometric cervical extension strength are highly reliable and can be used for the quantification of isometric cervical extension strength through a 126 degrees range of motion.(ABSTRACT TRUNCATED AT 250 WORDS)
