A new RP-HPLC method was developed for selective and simultaneous determination of betamethasone dipropionate and tolnaftate in combined semisolid formulation containing other components. Further, the proposed method was validated for linearity, precision (system precision, method precision, intermediate or inter-day precision), accuracy, stability in analytical solution, robustness or system s...

BACKGROUND Antenatal betamethasone is routinely used for the prevention of neonatal respiratory distress syndrome in preterm infants. However, little is known of the long term effects of exposure to antenatal betamethasone on lung function in adulthood. METHODS Five hundred and thirty four 30 year olds whose mothers had participated in the first and largest randomised controlled trial of ante...

BACKGROUND Interest in developing physically active pediculicides has identified new active substances. The objective was to evaluate a new treatment for clinical efficacy. METHODS AND FINDINGS We describe the selection of 1,2-octanediol as a potential pediculicide. Clinical studies were community based. The main outcome measure was no live lice, after two treatments, with follow up visits ov...

Background: Hyaluronic acids act upon keratinocytes via CD44 receptors and regulate proliferation and differentiation. Some cosmetic hyaluronan lotions manufactured based upon the fact are nowadays available. Aims: To evaluate a cosmetic hyaluronan lotion (Dr. Fukaya’s skin repair lotion or Hyaluprotect) from the viewpoint of anti-aging effects and to consider its mechanism. Patients/Methods: I...

BACKGROUND Topical application of the synthetic triterpenoid RTA 408 to rodents elicits a potent dermal cytoprotective phenotype through activation of the transcription factor Nrf2. Therefore, studies were conducted to investigate if such cytoprotective properties translate to human dermal cells, and a topical lotion formulation was developed and evaluated clinically. METHODS In vitro, RTA 40...

Scabies is caused by Sarcoptes scabiei var. hominis. The disease can be sexually transmitted. Patients' main complaint is nocturnal itch. Disseminated, excoriated, erythematous papules are usually seen on the anterior trunk and limbs. Crusted scabies occurs in immunocompromised hosts and may be associated with reduced or absent pruritus. Recommended treatments are permethrin 5% cream, oral iver...

Maternal administration of betamethasone to enhance fetal lung maturation for women who threaten preterm labor is common clinical practice. However, recommendations regarding the choice of betamethasone formulations for perinatal use are vague. The disposition of betamethasone from two commonly used antenatal formulations is poorly understood. We therefore designed a study to capture the true p...

Administration of L-carnitine or betamethasone to pregnant rats failed to increase either the total phospholipid or dipalmitoylphosphatidylcholine (DPPC) contents in foetal rat lungs on the 20th day of gestation, compared to controls. The combined administration of betamethasone (0.3 mg/kg) and L-carnitine (80 mg/kg) resulted in a pronounced increase of dipalmitoylphosphatidylcholine (7.8 +/- 2...
