CONCLUSION: Ex-prematurity and the presence of an underlying illness results in escalation of the direct treatment cost of RSV chest infection. Current guidelines for use of passive RSV immunization do not appear to be cost-effective if adopted for Malaysian infants.
DESIGN: Clinical case report.
SETTINGS: Tertiary referral center for infertility.
PATIENT(S): A married couple with primary subfertility secondary to azoospermia and male hypogonadotropic hypogonadism. The husband was a bodybuilder who admitted to have used the anabolic steroids testosterone cypionate, methandrostenolone, oxandrolone, testosterone propionate, oxymetholone, nandrolone decanoate, and methenolone enanthate.
INTERVENTION(S): Twice-weekly injections of 10,000 IU of hCG (Profasi; Serono) and daily injections of 75 IU of hMG (Humegon; Organon) for 3 months.
MAIN OUTCOME MEASURE(S): Semen analyses, pregnancy.
RESULT(S): Semen analyses returned to normal after 3 months of treatment. The couple conceived spontaneously 7 months later.
CONCLUSION(S): Steroid-induced azoospermia that is persistent after cessation of steroid use can be treated successfully with hCG and hMG.
METHODS: Nine healthy normotensive subjects participated in this randomized placebo-controlled two-way crossover study examining the effects of 5 days' pretreatment of nafcillin 500 mg or placebo four times daily on the pharmacokinetics of an oral dose of nifedipine 10 mg. Plasma nifedipine concentrations were measured by gas chromatography-mass spectro.
RESULTS: The area under the plasma nifedipine concentration-time curve (AUC0-alpha) in nafcillin-pretreated subjects (80.9 +/- 32.9 micro g l-1 h-1) was significantly decreased compared with subjects who received only nifedipine (216.4 +/- 93.2 micro g l-1 h-1) (P < 0.001). Total plasma clearance of nifedipine (CL/F) was significantly increased with nafcillin pretreatment (138.5 +/- 42.0 l h-1 vs 56.5 +/- 32.0 l h-1) (P < 0.002).
CONCLUSIONS: The results show that nafcillin pretreatment markedly increased the clearance of nifedipine and suggest that nafcillin is a potent inducer of CYP enzyme.
