PURPOSE: To evaluate whether there are any differences in MR findings between the childhood and the adult moyamoya disease. MATERIALS AND METHODS: We compared the brain MR findings in 22 children (13 boys and 9 girls, 2-18 years of age) who had moyamoya disease with 15 adult patients (7 men and 8 women, 19-55 years of age). The MR findings were classified as parenchymal-(infarctions and intracranial hemorrhages) and vascular abnormalities (intracranial vascular patency and moyamoya vessels). The difference in each of these MR findings was analyzed using Chi-squaretest and Fisher's exact test (two-tailed). Out of 22 children, two children with normal MR finding were excluded from the statistical analysis. Moyamoya diseases were diagnosed angiographically in all adult patients. In children, they were diagnosed by MR imaging, MR angiography(6), and/or conventional cerebral angiography(18). RESULTS: In children, cerebral infarctions were observed in 20 of 22 patients (91%) (cortex 86%, periventricular white matter/centrum semiovale 32%, basal ganglia 10%). In two patients, there was no parenchymal abnormality. Intra-cranial hemorrhages were not demonstrated in any patients. In adults, intra-cranial hemorrhages(intracerebral hematoma, intraventricular hemorrhage, alone or combined) were demonstrated in 10 of 15 patients(67%). Cerebral infarctions with or without intracranial hemorrhage were detected in 10 of 15 patients(67%)(cortex 40%, periventricular white matter/centrum semiovale 53%, basal ganglia 20%). The difference in parenchymal abnormalities between the childhood and the adult moyamoya disease was statistically significant (p=0. 000164). There was no significant difference between the two groups with regard to the occlusive changes of the internal carotid and middle cerebral arteries or to moyamoya vessels(p> 0.01 ). CONCLUSION: This study could prove the fact that the principal clinical symptoms in the childhood moyamoya disease were due to cerebral infarction and those in the adult cases were due to infarction and intracranial hemorrhage. In addition, cortical infarction was more prevalent in children and infarction in periventricular white matter/centrum semivoale and basal ganglia was more frequentin adults. There was no significant difference in vascular abnormalities between the two groups.

To elucidate the complex of insulin-like growth factor binding proteins (IGF-BPs) in short stature patients, we carried out a prospective study on three patients who were diagnosed as complete GH deficiency at the department of pediatrics from July 1992 to June 1993. The results were summarized as follows: 1) Two circulating IGFs complexed to specific binding protein existed in normal serum. Binding activity was found to be in the 150,000 molecular weight area (the large complex) and 50~60,000 molecular weight area (the small complex). 2) Binding activity for the large complex was seen to be dependent on advancing age, level of large IGF-BP3 complex peacked at the age of 15~16 years. 3) The binding activity for large complex diminished in three GH deficient patients and increased after hGH injection to near or above normal level. 4) Increased growth rate after GH treatment in GH deficient patient was closely related with increasing level of the large IGF-BP3 complex. Therefore we suggest that the large IGF-BP3 complex is regulated by GH. Estimating its serum level is useful for screening of GH deficiency and the monitoring of response to GH therapy.

Background: Reduced lipid content in the stratum corneum is a major cause of skin-barrier dysfunction in various pathological conditions. Promoting lipid production is a potential strategy to improve skin-barrier function. Recent evidence supports the beneficial effects of adiponectin on lipid metabolism and senescence in keratinocytes. Objective: This study aimed to investigate whether plant extracts can enhance skin-barrier function. Methods: We screened fruit and herb extracts that enhance the lipid synthesis of keratinocytes via AMP-activated protein kinase (AMPK) activation and SIRT1 signaling in the adiponectin pathway. The levels of major lipid synthesis enzymes and transcription factors as well as epidermal barrier lipids involved in adiponectin-associated epidermal barrier formation were evaluated in the herbal extracts- or adiponectin-treated human epidermal keratinocyte and equivalent models. The mRNA expression of major lipid synthesis enzymes increased following treatment with Lycii Fructus, Prunus tomentosa, and Melia toosendan extracts. Results: The expression of transcription factors SIRT1, liver X receptor α, peroxisome proliferator-activated receptors (PPARs), and sterol regulatory element-binding proteins (SREBPs) were upregulated. Levels of free fatty acids, cholesterol, and ceramides were elevated. The expression of keratinocyte differentiation markers increased. In particular, among fruit extracts with a detectable effect, Melia toosendan induced the highest expression of lipid synthase. Conclusion These results indicate that Melia toosendan is a promising candidate for improving skin-barrier function.

Nail psoriasis is a common finding in psoriatic patients and is associated with substantial adverse effects on the patient's quality of life. Although several treatment options are available, nail psoriasis tends to be persistent and refractory to therapy. Pulse dye laser (PDL) has been demonstrated to be effective for plaque-type psoriasis, but there are no reports on nail psoriasis being successfully treated with PDL in the Korean literature. We here report on a 46-year-old woman presenting with nail psoriasis recalcitrant to conventional treatment modalities, showing pitting, nail bed discoloration, and crumbling. We successfully treated the symptoms with 595 nm PDL, supporting the hypothesis that PDL may be a safe and effective therapeutic option in patients with recalcitrant nail psoriasis.

PURPOSE: We presented our initial clinical experiences with transumbilical laparoendoscopic single-site (LESS) ureterolithotomy for large, impacted ureteral stones. MATERIALS AND METHODS: Between March 2009 and November 2009, seven LESS ureterolithotomies were performed at our institute. During the operation, we made a single 2 cm incision at the umbilicus and a homemade port by using a small wound retractor (Alexis(R), Applied Medical, Rancho Santa Margarita, USA), a surgical glove, and conventional trocars. The operation was performed in the same manner as conventional laparoscopic surgery. The mean maximal stone diameter was 21.9 mm (range, 16.0-27.0 mm). There were six cases of upper ureteral stones and one case of a mid-ureteral stone. Perioperative and postoperative parameters were evaluated. RESULTS: The mean operative time was 197.1 min (range, 150-270 min). No transfusions were required. The mean postoperative hospital stay was 3.3 days (range, 2-6 days). The mean pain intensity on a visual analogue scale (VAS) on postoperative day 2 was 26 mm (range, 0-80 mm), and the mean cosmetic VAS at 6 weeks after the operation was 0 mm. The mean time for patients to return to their baseline activities was 4.0 days (range, 3-7 days). In six cases, all stones were completely removed on the basis of postoperative radiologic evaluation. There were no cases of major complications, including internal organ injury, urinary leakage, or urinary tract infection. CONCLUSIONS: Transumbilical LESS ureterolithotomy can be considered as an alternative treatment option with minimal invasiveness and good effectiveness for large, impacted ureteral stones.

Lipoma is the most common benign mesenchymal neoplasm composed of mature fat. Although lipoma can occur in any part of the body, it is infrequently found in the oral cavity. Especially, lipoma of the tongue is rare and there have been no previous reports of this in the Korean dermatology literature. Lingual lipoma, which accounts for 0.3% of all tongue neoplasm, is typically described as well-circumscribed, submucosal mass and it is located on the lateral border of the anterior two-thirds of the tongue surface. We herein report on a rare case of lipoma of the tongue that occurred in a 77-year old male patient.

Bier's spots present as vascular mottling, and this consists of small, irregular macules surrounded by a red to cyanotic background. The macules most commonly occur on the arms and legs of young adults, but they may also appear on the trunk. They are considered a vascular anomaly, with vasoconstriction in the pale areas and vasodilatation in the erythematous skin. Although Bier's spots are occasionally discovered in young adults, they are still a challenge to differentiate from other hypopigmentation disorders. We report here on two cases of Bier's spots on the extremities and trunk of 2 young adults.

BACKGROUND: The clinical presentation of lichen planus varies depending on the area involved. It occurs in less than 1% of the world's population: also, the prevalence in Korea is relatively low. However, the number of our outpatients has been increasing rapidly. OBJECTIVE: We studied the clinical characteristics of 100 patients with biopsy proven lichen planus. METHODS: We reviewed the medical records and clinical photographs of 100 patients who had been diagnosed with lichen planus during the last 10 years, from January 2002 to December 2011. RESULTS: Over the past 10 years, patients with Lichen Planus accounted for 0.196% among the new outpatients of this dermatology. The rate of Lichen Planus increased when it occurred on the skin, except for the Mucosal area. Of the 100 outpatients, 62% were men and 38% were women. The mean age at diagnosis was 54 years, and more than half of the patients were between 40 and 60 years of age. The most common site of lichen planus was the lip, which was found in 44% of the patients. Oral lesions were the second most commonly involved site at 28%, followed by the body at 20% and the genital area at 8%. The patients complained of various symptoms such as pain, burning sensation, pruritus, and irritation. Various treatments had been tried by all patients. CONCLUSION: This study of domestic patients with Lichen Planus is the biggest clinical research performed at a single center. The clinical features of patients in this survey share many similarities with those reported previously, but showed some differences too.
