Lichen nitidus(LN) is an uncommon chronic inflammatory disease of shiny, flat-topped, flesh-colored uniform papules most commonly located on the penis, forearms and wrists, lower abdomen, and thighs. LN almost has localized distribution, but in rare cases, it may become generalized. In Korea, three cases of generalized LN were reported. We report here three cases of generalized lichen nitidus in 31-year-old man, 8-year-old boy, and 6-year-old girl who had generalized numerous pinhead-sized, erythematous to flesh-colored, shiny papules. Microscopically, they had typical appearance of LN.

Recent clinical trials have demonstrated the values of cardiac computed tomography (CT) in the initial evaluation of stable chest pain which led to drastic changes in the National Institute for Health and Care Excellence (NICE) guidelines in 2016. According to the updated NICE guidelines, cardiac CT should be performed as the initial cardiac testing in stable chest pain regardless of pre-test probability (PTP) of coronary artery disease (CAD). As a result, cardiac CT is now considered as a validated gatekeeper for assessing stable chest pain, which precedes all the functional studies including nuclear myocardial perfusion imaging (MPI). Nuclear MPI, in contrast, has been assigned as one of the second-line studies, which is inevitably dependent on the results of cardiac CT. However, nuclear MPI has genuine values in the diagnosis, treatment decision, and prognostic stratification of stable chest pain, which cannot be replaced by cardiac CT. In this review, the updated NICE guidelines and related cardiac CT trials will be critically reviewed from the view of nuclear physicians and the exceptional values of nuclear MPI will be described along with the future perspectives.

PURPOSE: To evaluate the MR findings of gestational trophoblastic tumor(GTT) in correlation with pathological results. MATERIALS AND METHODS: Nine patients who confirmed the diagnosis (four choriocarcinomas and five invasive moles) constituted the basis of our study. Pathologic specimens were taken from the tumors corresponding to the regions of interest on MR images. The MR images were analyzed in respect of the morphology and signal intensity of the tumors, uterine and adnexal vascularity, and the adnexal lesion. RESULTS: The MR findings of four choriocarcinomas were well-defined, hemorrhagic masses with central necrosis;the masses were hyperintense on Tl-weighted images. In contrast, the five invasive moles showed irregular and permeative masses with densely enhanced solid components and tiny cystic lesions. The trophoblastic proliferation, coagulation necrosis, and molar villi had variable signal intensities on Tl-and T2-weighted images. CONCLUSION: Our results suggest that MR imaging is a promising tool for noninvasive morphologic analysis of GTTS.

BACKGROUND: Topical application of corticosteroids also has an influence on skin barrier impairment. Physiological lipid mixtures, such as multi-lamellar emulsion (MLE) containing a natural lipid component leads to effective recovery of the barrier function. OBJECTIVE: The purpose of this study was to conduct an evaluation of the therapeutic efficacy and skin barrier protection of topical mometasone furoate in MLE. METHODS: A multi-center randomized, double-blind, controlled study was performed to assess the efficacy and safety of mometasone furoate cream in MLE for Korean patients with eczema. The study group included 175 patients with eczema, who applied either mometasone furoate in MLE cream or methylprednisolone aceponate cream for 2 weeks. Treatment efficacy was evaluated using the physician's global assessment of clinical response (PGA), trans-epidermal water loss (TEWL), and visual analogue scale (VAS) for pruritus. Patients were evaluated using these indices at days 4, 8, and 15. RESULTS: Comparison of PGA score, TEWL, and VAS score at baseline with those at days 4, 8, and 15 of treatment showed a significant improvement in both groups. Patients who applied mometasone furoate in MLE (74.8%) showed better results (p<0.05) than those who applied methylprednisolone aceponate (47.8%). The TEWL improvement ratio was higher in the mometasone furoate in MLE group than that in the methylprednisolone aceponate group, and VAS improvement was also better in the mometasone furoate in MLE group. CONCLUSION: Mometasone furoate in MLE has a better therapeutic efficacy as well as less skin barrier impairment than methylprednisolone aceponate.
