ABSTRACT
We analysed retrospectively pharmacokinetic parameters of gentamicin and amikacin in 44 and 58 Korean pediatric patients, respectively, with normal renal function. Pharmacokinetic parameters were calculated from two concentrations in serum by method of Sawchuck. There was wide individual variation in peak serum concentrations of gentamicin and amikacin, Administration of the usually recommended doses yielded subtherapeutic concentrations in 47% and 82%, respectevely, of patients in the peak concentrations of gentamicin and amikacin. The volumes of distribution of gentamicin and amikacin in children of over 1 year of age were 0.37+/-0.13L/kg and 0.41+/-0.13L/kg which are greater than those reported from the western countries. We conclude that the wide individual variation and high frequency of subtherapeutic levels in the peak concentrations of gentamicin and amikacin obtained by usually recommended dosage as well as the narrow safety margin of these drugs necessitate monitoring of serum concentration and adjustment of individual dosage regimen early in the course of treatment with aminoglycosides.

Diaper dermatitis is an infant dermatosis associated with the wearing of diapers, Despite of its high frequency in clinical pediatrics the clinical characteristics are not well described in the korean literatvre. We investigated the clinical and mycological characteritics of diaper dermatitis in 50 serial patients. Clinically diaper dermatitis was classified. into five categories,irritant contact derniatitis(ID), candidiasis(CD). combined rash of ID and CD(CR.), intertrigo, and miliari. Of 50 patients with diaper dermatitis, 18 had ID; 16, CI3; 10, CR; 5, intertrigo, and 1, miliaria, The mean age of patients with ID (11.8 months) was higher than that of patients with CD (4.0 months). Candida albicans(C. albicans) w is isolated from 25 patients with diaper dermatitis. The rate of positive cultures by clinical diagnosis was 130% in CD, 11.1% in ID, 60, 0% in CR, and 20.0% in intertrigo. C. albicons was isolated from 23 patients(82.1%) of patients with clinically suspected Ci") and 2 of 22 patients without the characteristic erythematous papulesThe presence of eryhematous papules was the most characteristic clinical feature of infection, Other candida species isolated from cut,aneous lesions were C. tropicalsis, C.'. parapsiolosis, and C. stellatoidea.
