BACKGROUND: A fixed-dose combination gel with adapalene 0.1% and benzoyl peroxide (BPO) 2.5% has been developed for once-daily treatment of acne. It is known to be effective to reduce inflammatory and non-inflammatory lesions, but there have been no study in Korean yet. OBJECTIVE: The aim of this study was to evaluate the efficacy and safety of adapalene 0.1%-BPO 2.5% fixed-dose combination gel (adapalene-BPO) for the treatment of mild to moderate severity acne in Korean. METHODS: In total, 64 patients with mild to moderate severity acne were enrolled. Adapalene-BPO was applied to face once daily at night. The efficacy assessment was performed at baseline and monthly for 3 months: inflammatory lesions (IL), non-inflammatory lesions (NIL), total lesions (TL) were counted and median percentage changes of each lesion were measured for 3 months with patient satisfaction and adverse events questionnaire. RESULTS: Of the 64 patients enrolled, 58 have completed 3-month treatments. Adapalene-BPO showed early onset of action with significant reduction in inflammatory, non-inflammatory, and total lesion counts. The median percentage reduction of mild group from baseline to 3rd month was greater than moderate group in IL, NIL, and TL counts (71.1% vs 65%/61.4% vs 56.4%/67.7% vs 62% reduction). Also, patient satisfaction score improved and significant reduction of Korea Acne Grading System (KAGS) was noted in both groups. All the reported adverse events were mild. CONCLUSION: This study shows that adapalene-BPO is an effective and safe treatment regimen for both mild and moderate acne. It has a better effect for treating mild severity acne than moderate acne with reduction of the IL, NIL, and TL counts and greater patient satisfaction.

[Ca2+]i transients by reverse mode of cardiac Na+/Ca2+ exchanger (NCX1) were recorded in fura-2 loaded BHK cells with stable expression of NCX1. Repeated stimulation of reverse NCX1 produced a long-lasting decrease of Ca2+ transients ('rundown'). Rundown of NCX1 was independent of membrane PIP2 depletion. Although the activation of protein kinase C (PKC) was observed during the Ca2+ transients, neither a selective PKC inhibitor (calphostin C) nor a PKC activator (PMA) changed the degrees of rundown. By comparison, a non-specific PKC inhibitor, staurosporine (STS), reversed rundown in a dose-dependent and reversible manner. The action of STS was unaffected by pretreatment of the cells with calphostin C, PMA, or forskolin. Taken together, the results suggest that the stimulation of reverse NCX1 by STS is independent of PKC and/or PKA inhibition.

Tinea corporis is dermatophytosis of trunk and extremities except terminal hair present region. We report a case of psoriasiform tinea corporis in a 11-year-old girl. The lesions were showed multiple, pruritic, thick scaly erythematous macules and patches on the left forearm and trunk. She had been treated with topical and oral corticosteroid for 5 months. Direct microscopic examination and fungal culture were positive for hyphae and colonies of Microsporum canis. Histopathologic examination of the skin lesion revealed parakeratosis, psoriasiform epidermal hyperplasia and perivascular inflammatory infiltration in upper dermis with presence of fungal hyphae in stratum corneum. She was treated with 250mg of terbinafine daily and topical lanoconazole for 1 month. Skin lesions cured without recurrence.

OBJECTIVETo assess the efficacy of dapoxetine on demand for premature ejaculation and provide evidence for clinical decision-making.

METHODSWe searched PubMed, Embase, BIOSIS Previews, Cochrane Library, CNKI Database and Wanfang Database for literature on dapoxetine on demand for premature ejaculation. We performed meta-analysis on the identified publications and evaluated its therapeutic efficacy based on the intravaginal ejaculatory latency time (IELT), patient-reported global impression of change (PGI), and composite PRO criteria for clinical benefit (CCCB).

RESULTSFour relevant studies were included involving 6 081 cases of premature ejaculation. Compared with the placebo controls, the patients treated with dapoxetine on demand showed significant improvement in IELT (WMD = 1.39, 95% CI [1.23, 1.55], P < 0.000 01), PGI (OR = 2.59, 95% CI [2.21, 3.04], P < 0. 000 01), and CCCB (OR = 2.59, 95% CI [1.98, 3.39], P < 0.000 01). There were significant differences between the 60 mg and 30 mg dapoxetine groups in IELT (WMD = 0.46, 95% CI [0.19, 0.74], P = 0.001 0) and PGI (OR = 1.32, 95% CI [1.06, 1.64], P = 0.01), but not in CCCB (OR = 1.39, 95% CI [0.90, 2.15], P = 0.13).

CONCLUSIONDapoxetine on demand can prolong IELT and improve PGI and CCCB, either at the dose of 60 mg or 30 mg, and has an even better efficacy in prolonging IELT and improving PGI at 60 mg.

Xuezhikang capsule (ethanol extract of red yeast rice) which produced by Beijing WBL Peking University Biotech Co., Ltd., is a traditional Chinese medication with 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibiting activity. Clinical trials indicated that Xuezhikang with lipid-lowering action could reduce the risk of cardiac events and total mortality of Chinese coronary heart disease patients. To exactly explain the clinical features of Xuezhikang, we undertook a complete study of the chemical constituents of Xuezhikang. This study resulted in the isolation of a new monacolin analogue, named alpha, beta-dehydromonacolin L (1), along with two known compounds: monacolin L (2) and 3-(2, 6-dimethyl-1, 2, 4a, 5, 6, 7, 8, 8a-octahydronaphthalen-1-yl)propanoic acid (3). The chemical structures were determined by extensive 1D and 2D NMR and MS spectroscopic analysis.

Tinea capitis, a dermatophyte infection involving the hair shaft on the scalp, is primarily a disease of preadolescent children. Trichophyton or Microsporum species of dermatophytes transmitted by humans or animals are commonly associated with this disease. Clinical presentations are seborrheic-like scale, 'black dot' pattern, inflammatory tinea capitis with kerion or tiny pustules in the scalp. We report an interesting case of tinea capitis with rapid progression caused by Trichophyton mentagrophytes in an 11-year-old girl. The patient was treated with 125 mg of oral terbinafine and topical flutrimazole cream for one month.

BACKGROUND: Luliconazole (LLCZ) is an imidazole antifungal agent widely used in Japan for treatment of tinea, cutaneous candidiasis, and pityriaisis versicolor, etc. Theoretically, its potent antifungal activity should make it a viable option for various conditions of dermatophytoses, but there has been no studies to support the notion thus far. OBJECTIVE: This prompted the authors to investigate the distribution of minimum inhibitory concentration (MIC) of luliconazole by carrying out in vitro antifungal susceptibility test on Trichophyton (T.) species clinically isolated from Korean subjects with tinea pedis. METHODS: In vitro antifungal susceptibility test, with broth macrodilution method of luliconazole and terbinafine hydrochloride (TBF) as reference drug on two clinically isolated Trichophton species (22 strains of T. rubrum, 5 of T. mentagrophytes), was carried out. RESULTS: The range of MIC for LLCZ on the total of 27 strains was 0.0110~0.0140 microg/mL (geometric mean: 0.0027 microg/mL), and the range for TBF was 0.0120~0.0250 microg/mL (geometric mean: 0.0042 microg/mL). Additionally, the geometric mean for MIC of LLCZ on T. mentagrophytes was 0.0125 microg/mL, and on T. rubrum, it was 0.0019 microg/mL. No strain showed resistance in vitro. CONCLUSIONS: The authors hence demonstrated that antifungal activity of LLCZ in vitro against Trichophyton species clinically isolated from Korean subjects is quite superior. These findings emphasize the usefulness of LLCZ, a promising new imidazole, for the topical management of dermatophytoses.
