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.

BACKGROUND AND PURPOSE: Although thrombolytic strategies with streptokinase(STK) and tissue-type plasminogen activator(t-PA) in the treatment of acute myocardial infarction(AMI) have been studied in large-scale clinical trials in the western countries, such large-scale studies with urokinase(UK) are scanty. Even though UK is most commonly used thrombolytic agent for the treatment of AMI in Korea, there is no consensus on the dosage and the way of administration of UK in patients with AMI. Accordingly, a prospective clinical study was performed to evaluate the effects of thrombolytic strategies of intravenous double bolus method and standard double-infusion method with different dosage of UK in the treatment of AMI. SUBJECTS AND METHODS: Ninety there patients with AMI(male 75, female 18, age 57.5+/-10.8 years) were studied. The patients were divided into 3 groups according to dosage of UK and method of administration. Group I : 19 patients who received 1.5 million U of UK IV bolus, followed by 1.5 million U IV infusion for an hour(High Dose Group). Group II : 34 patients received 20,000U/kg body weight of UK IV bolus, followed by 20,000U/kg IV infusion for an hour(Double Dose Group). Group III : 40 patients received 1.5 million U of UK IV bolus and followed by 20,000U/kg IV bolus in 30 minutes with total dose of no more than 3 million U(Double Bolus Group). Coronary angiography(CAG) and left ventriculography(LVG) were performed 90 minutes after the administration of UK and post-AMI 7-10 days to investigate the patency of infarct-related artery(IRA) and LV function. Patency of IRA was graded according to the extent of flow of IRA. TIMI grade 0-1 was regarded as occluded, and grade 2-3 flow as patent. LV ejection fraction(EF) by echocardiography was measured on day 1, day 7-10 and 1 month after AMI. Indirect clinical parameters of thrombolysis were evaluated and were compared with CAG findings. RESULTS: 1) The 90 minutes IRA patency in Group III(Double bolus ; 79.0%) was higher than that in Group 1, but showed no statistically significant difference(High dose ; 61.5%, p=0.790). The 90 minutes IRA patency in Group III showed borderline significance with Group II(Double dose ; 57.1%, p=0.057). TIMI flow III in Group III(60.6%) was significantly higher than that in Group II(53.6%, p=0.0468) but showed no statistically significant difference with Group I(61.5%, p=0.158). 2) The EF by LVG were 49.1% in Group I, 41.7% in Group II and 49.2% in Group III. The difference in EF between Group I and Group III vs Group II was significant(p=0.008 in Group I, p=0.014 in Group III vs Group II). 3) Fatal bleeding complications(1 intracranial hemorrhage and 1 gastric ulcer bleeding) developed in Group II (Double dose). 4) Pain to door time, pain to needle time and door to needle time tended to be shorter in open(TIMI flow II-III) IRA group than in closed IRA group. 5) Initial EF were similar between open IRA group and closed IRA group(46.1% and 42.1% ; p=NS). The EF of open IRA group measured by LVG on initail coronary angiography(41.8% in closed IRA vs 48.0%, in open IRA, p=0.03) and by 2D-Echo on 7-10 day(41.7% in closed IRA vs 51.0% in open IRA, p=0.004) were better than those of closed IRA group. 6) Indirect clinical indices of reperfusion such as mean CPK peak, time to CPK peak significantly lower in open IRA group than in closed IRA group. 7) Fatal bleeding complications(1 intacranial hemorrhage and 1 gastric ulcer bleeding) developed in closed IRA group. CONCLUSION: The findings we observed in this trial showed that earlier initiation and more rapid infusion of UK were associated with more increased 90min patency of infarct-related artery and more improved LV function without any obviously increased bleeding complications or other serious life-threatening complications than conventional UK therapy. Specifically, double bolus IV injection of UK(1.5 million U bolus followed by 20,000 U/Kg bolus in 30min)was more effective method of thrombolysis than conventional method for achieving optimal reperfusion in AMI patients. Also, IRA patency at 90 minutes after the initiation of thrombolysis was important in preserving global LV function in early recovery phase of AMI. Further trials may be needed to determine more effective thrombolysis with UK in AMI.

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.
