PURPOSE: We studied short-term effects of steroid and anti-inflammatory drugs on collagen synthesis in rat skin. MATERIALS AND METHODS: The 18 rats were divided equally into three groups: group I; piroxicam, group II; triamcinolone, group III; saline. All drugs were given by intraperitoneal injection. Drugs were administered to rats for 4 days after dorsal skin incision. One day after operation and at 24 hour interval there after, skin tissues containing subcutaneous fat were randomly harvested. Measurement procedures were composed of three steps: the first was Masson's trichrome stain for collagen tissue identification; the second involved transporting the image to a computer and the third the analyses of the collagen area using a morphometry program. RESULTS: Statistically significant differences were found in the mean values of the relative collagen contents of the triamcinolone and saline injection groups on the third day (p<0.05). Relative collagen content of the saline injection group was greater than those of the other groups. The triamcinolone group showed the least collagen content. Collagen content of groups increased in time. CONCLUSION: Steroid had an inhibitory effect on the synthesis of collagen. Anti-inflammatory drugs also reduced the amount of collagen synthesis, but without statistical difference.

A variety of disease states are marked by prolonged and profound eosinophilia associated with localized or widespread eosinophilic infiltrates. Cardiac involvement maybe a major cause of morbidity and mortality of this disease. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocardilic myocarditis by endomyocardial biopsy.

Lichen spinulosus is a benign follicular eruption seen primarily in younger persons and is frequently classified a disorder of keratinization. The lesion is characterized by the development of patches of small perifollicular papules that have a central horny spine. We report a case of lichen spinulosus developed in an 8-year-old male patient who had atopic dermatitis.

OBJECTIVE: The study’s aim was to develop and standardize a Korean version of the University of California San Diego Performance-based Skills Assessment (K-UPSA), which is used to evaluate the daily living function of patients with schizophrenia. METHODS: Study participants were 78 patients with schizophrenia and 27 demographically matched healthy controls. We evaluated the clinical states and cognitive functions to verify K-UPSA’s reliability and validity. For clinical states, the Positive and Negative Syndrome Scale, Clinical Global Impression-Schizophrenia scale, and Social and Occupational Functioning Assessment Scale and Schizophrenia Quality of Life Scale-fourth revision were used. The Schizophrenia Cognition Rating Scale, Short-form of Korean-Wechsler Adult Intelligence Scale, and Wisconsin Card Sorting Test were used to assess cognitive function. RESULTS: The K-UPSA had statistically significant reliability and validity. The K-UPSA has high internal consistency (Cronbach’s alpha, 0.837) and test-retest reliability (intra-class correlation coefficient, 0.381–0.792; p<0.001). The K-UPSA had significant discriminant validity (p<0.001). Significant correlations between the K-UPSA’s scores and most of the scales and tests listed above demonstrated K-UPSA’s concurrent validity (p<0.001). CONCLUSION: The K-UPSA is useful to evaluate the daily living function in Korean patients with schizophrenia.

OBJECTIVE: This multi-center, randomized, double-blind, phase 3 trial was conducted to compare the safety and efficacy of contrast agents iohexol-380 and iohexol-350 for coronary CT angiography in healthy subjects. MATERIALS AND METHODS: Volunteers were randomized to receive 420 mgI/kg of either iohexol-350 or iohexol-380 using a flow rate of 4 mL/sec. All adverse events were recorded. Two blinded readers independently reviewed the CT images and conflicting results were resolved by a third reader. Luminal attenuations (ascending aorta, left main coronary artery, and left ventricle) in Hounsfield units (HUs) and image quality on a 4-point scale were calculated. RESULTS: A total of 225 subjects were given contrast media (115 with iohexol-380 and 110 with iohexol-350). There was no difference in number of adverse drug reactions between groups: 75 events in 56 (48.7%) of 115 subjects in the iohexol-380 group vs. 74 events in 51 (46.4%) of 110 subjects in the iohexol-350 group (p = 0.690). No severe adverse drug reactions were recorded. Neither group showed an increase in serum creatinine. Significant differences in mean density between the groups was found in the ascending aorta: 375.8 ± 71.4 HU with iohexol-380 vs. 356.3 ± 61.5 HU with iohexol-350 (p = 0.030). No significant differences in image quality scores between both groups were observed for all three anatomic evaluations (all, p > 0.05). CONCLUSION: Iohexol-380 provides improved enhancement of the ascending aorta and similar attenuation of the coronary arteries without any increase in adverse drug reactions, as compared with iohexol-350 using an identical amount of total iodine.

OBJECTIVE: This study aimed to evaluate the clinical efficacy, safety, and tolerability of paliperidone extended release (ER) in patients with schizophrenia by switching previous antipsychotics to paliperidone ER. METHODS: An open-label, 24 weeks, prospective, non-comparative, multi-center study evaluated total 387 patients with schizophrenia requiring a switch in antipsychotic medication due to suboptimal efficacy, intolerability, and non-compliance. Patients were switched to flexible-dose trial of paliperidone ER (3-12 mg/day). Efficacy was measured by Krawiecka Scale, Clinical Global Impression-Schizophrenia-Severity (CGI-SCH-S), Clinical Global Impression-Schizophrenia-Improvement (CGI-SCH-I), sleep visual analog scale (VAS), and Personal and Social Performance Scale (PSP). Safety assessments included adverse events (AEs), evaluation of extrapyramidal symptoms (EPS) using the Drug Induced Extrapyramidal Symptoms Scale (DIEPSS), and laboratory tests. RESULTS: Data from a total of 321 subjects who took the paliperidone ER and had at least one follow-up assessment without a major protocol violation were analyzed. Switching to paliperidone ER led to a significant improvement in the Krawiecka, CGI-SCH-S, CGI-SCH-I, PSP, and DIEPSS scales. However, serum prolactin levels and metabolic parameters including body weight and waist circumference were significantly increased. Insomnia was the most common adverse event. CONCLUSION: This study suggested that patients with schizophrenia who showed insufficient response or intolerance to other previous antipsychotics can be switched to paliperidone ER, with efficacy, safety, and tolerability.

This study attempted to calculate and investigate the incidence of hospitalized acute myocardial infarction (AMI) and stroke in Korea. Using the National Health Insurance claim data, we investigated patients whose main diagnostic codes included AMI or stroke during 2006 to 2010. As a result, we found out that the number of AMI hospitalized patients had decreased since 2006 and amounted to 15,893 in 2010; and that the number of those with stroke had decreased since 2006 and amounted to 73,501 in 2010. The age-standardized incidence rate of hospitalized AMI, after adjustment for readmission, was 41.6 cases per 100,000-population in 2006, and had decreased to 29.4 cases in 2010 (for trend P < 0.001). In the case of stroke was estimated at 172.8 cases per 100,000-population in 2006, and had decreased to 135.1 cases in 2010 (for trend P < 0.001). In conclusion, the age-standardized incidence rates of both hospitalized AMI and stroke in Korea had decreased continuously during 2006 to 2010. We consider this decreasing trend due to the active use of pharmaceuticals, early vascular intervention, and the national cardio-cerebrovascular disease care project as the primary and secondary prevention efforts.
