RESUMO
Objective To establish a RP-HPLC method for determination of ketoconazole, mupirocin and mometasone furoate in compound ketoconazole ointment. Methods RP-HPLC was conducted on a Intersil ODS-3 column (250 mm×4.6 mm, 5 μm), with methanol-PBS with pH 5.5 (65:35) as the mobile phase and the column temperature was 45 ℃. The flow rate was 1.0 ml/min, and the detection wavelength was 248 nm. Results The methodological verification showed that ketoconazole, mupirocin and mometasone furoate had a good linearity (r≥0.9995). The inter/intra-day precisions were less than 3.0%, The recovery rates were between 90% and 108%. The stability and repeatability of RSD were also less than 3.0%, which met the requirements of method validation. The contents of the three components in three batches were determined by the new method. Conclusion The method is simple and reliable. It can provide a basis for the quality control of compound ketoconazole ointment and lay a foundation for its quality standard research.
RESUMO
We report a case of suspected fetal congenital glaucoma detected by prenatal ultrasound. The mother had no history of cold, medication, or radiation exposure in the first trimester. Routine prenatal ultrasound at 23 +2 weeks of gestation found a 2.5 mm ventricular septum defect, and the sagittal and transverse diameters of the left and right eyeballs were all greater than the normal range of the same gestational weeks, which were noted at 18.57 mm and 17.26 mm, 18.21 mm and 17.22 mm, respectively. Dynamic observation revealed that the bilateral eyelids were unable to close with cornea being exposed to amniotic fluid. The pregnancy was terminated at 23 +6 weeks and a stillborn female weighing 650 g was delivered two days later. Congenital glaucoma was highly suspected by postnatal ophthalmic examination, accompanied by a deformity of the left thumb. No abnormality was detected on fetal chromosome karyotyping or whole-exon sequencing. When unilateral or bilateral megalophthalmos in the fetus is detected by prenatal ultrasound, congenital glaucoma should be considered.
RESUMO
<p><b>OBJECTIVE</b>To investigate the risk factors of vaginal dilators by 567 adverse event reports, and to provide a reference for the reasonable use.</p><p><b>METHODS</b>With retrospective case study, analyzed 567 reports induced by vaginal dilators by National Adverse Drug Reaction Monitoring Center in 2012.</p><p><b>RESULTS</b>Expected treatment of disease might be relevant with severity of adverse events, while age was not the related factor; the influencing factor of consequences of grading was the classification of the cause of adverse events.</p><p><b>CONCLUSION</b>Monitoring should be strengthen in order to reduce or avoid the vaginal dilator adverse events.</p>
