Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Single-dose oral temafloxacin versus parenteral ceftriaxone in the treatment of gonococcal urethritis/cervicitis.
Temafloxacin is an oral fluoroquinolone with potent in vitro activity against Neisseria gonorrhoeae. The efficacy and safety of a single dose of temafloxacin were compared with ceftriaxone, the current treatment of choice for gonorrhea, in a randomized, multicenter study. A total of 421 patients with uncomplicated gonococcal urethritis or cervicitis were randomly assigned to receive a single oral dose of temafloxacin 200 mg (n = 63) or 400 mg (n = 175), or a single intramuscular injection of ceftriaxone 250 mg (n = 183). ⋯ Corresponding clinical cure rates were 93.6% and 94.6%, respectively. Both regimens were well tolerated. A single oral dose of temafloxacin appears to be as safe and effective as injectable ceftriaxone in the treatment of uncomplicated gonococcal urethritis or cervicitis.

To examine the differential effect of stress ulcer prophylaxis on overt bleeding, clinically important bleeding, and mortality in critically ill patients. ⋯ Overt gastrointestinal bleeding in critically ill patients is reduced by prophylaxis with antacids or histamine-2-receptor antagonists. Histamine-2-receptor antagonists are more effective than antacids at decreasing overt bleeding and are more effective than no treatment at reducing the incidence of clinically important bleeding. Mortality rates in the intensive care unit are not decreased by stress ulcer prophylaxis.

Incidence, predictability, and pathogenesis of amiodarone-induced thyrotoxicosis and hypothyroidism.
To determine the incidence and predictability and to elucidate the pathogenesis of amiodarone-induced thyrotoxicosis (AIT) and hypothyroidism (AIH). ⋯ In euthyroid subjects living in an area with a moderately sufficient intake of iodine, there is a higher incidence of AIT than of AIH. AIH is an early event, occurring especially in women with thyroid autoantibodies prior to treatment. Cases of AIT continue to occur during amiodarone therapy; its development is unpredictable and of unexplained sudden onset. The value of regular thyroid function testing is therefore limited during amiodarone administration.
