We report a patient who had been initially diagnosed as a myelodysplastic syndrome in 1998 presenting purpuric patches on the left arm that started to develop about a year prior. The purpuric lesions were diagnosed as leukemia cutis by skin biopsy. Her subsequent bone marrow biopsy showed progression into an atypical chronic myeloid leukemia with increased numbers of leukocytes in the peripheral blood. Leukemia cutis typically is regarded as a sign of progression of disease or a manifestation of recurrent disease in treated patients with an established diagnosis of leukemia. We suggest that the skin lesion in this patient could have been a sign of con-version into atypical chronic myeloid leukemia.

Plasmid vectors with either RSV or CMV promoter are frequently used for DNA- mediated immunization due to the availability in commercial. Consequently, influence of the vector constituents, such as promoter, enhancer and transcription termination signal etc. on vaccination efficiency is not studied extensively. As an initial attempt to develop an efficient vector system for DNA-rnediated immunization, influence of promoter for antigen gene expression on vaccination efficiency has been analyzed. Initially, plasmids with either B-actin or muscle creatine kinase (MCK) promoter were constructed from the plasmid with prototype CMV promoter. In addition, ovalbumin (OVA) antigen gene has been cloned into each vectors to generate the plasmid vectors with different promoters for induction of the anti-OVA immune responses. Antigen protein expression in antigen gene transfected mouse muscle myoblast cells showed that the level from MCK promoter containing plasmid was slightly higher than those from either CMV or B-actin promoter containing plasmids. Also, the same plasmid turned out to be slightly more efficient than other plasmids in antibody imrnune response induction in vivo, when they were applied both through intramuscularly and intradermally. These results suggest that the commonly used CMV promoter containing plasmid vector could be further modified to develop an efficient vector for DNA-mediated immunization.

Acute generalized exanthematous pustulosis(AGEP) is a disease entity caused mostly by drugs or viral infections. Clinically it manifests as generalized erythema, erythema multiforme and amicrobial pustules with fever. Histologically, AGEP is composed of neutrophilic subcorneal and spongiform pustules. A 70-year-old female, with no personal or family history of psoriasis, was given medication including diltiazem for hypertension. Fourteen days after taking the medications, pustular eruptions appeared on the face and rapidly spread to the trunk and limbs. A Laboratory examination revealed neutrophilic leukocytosis and an elevated erythrocyte sedimentation rate. The skin biopsy showed subcorneal and spongiform pustules. We report here a case of AGEP probably due to diltiazem.

The fractures of the ankle in children are differ from those of adults in terms of the fracture pattern and the possibilities of influence to growth. The injuries of the ankle in children occur mostly at the bony structure rather than ligamentous structure, and some injuries of the growth plate may result in the arrest of entire growth plate or parts of growth plate and these may lead to leg length discrepancy or deformity. Many authors agree that the prognosis of injuries of the growth plate is dependent on the fracture type, the age of the patient at the onset of injuries, the degree of displacement of the fracture fragments, whether the injuries open or closed, and the efficacy of reduction. But the authors can not postulate one uniformed method of classification and treatment of the children's ankle fracture because of the variability of injuries. We have reviewed 35 cases of children's ankle fracture treated at our clinics from Dec. 1979 to Feb. 1984. The results obtained are as follows: l. Over half of the patients were between the ages of 13 and 16 years (54.3%). 2. The incidence of each type as Salter-Harris classification was that of type II(48.6%), type I(20.0%),type III(14.3%),type IV (8.6%). 3. The traffic accidents were the main causes of injury (68.5%). 4. The type I fractures occured mostly under 10 years of age and the type II fractures in adolescents. 5. All the type I fractures were treated conservatively without any complication, and the type II fractures were treated conservatively in 13 cases (76.5%) and operatively in 4 cases (23.5%) with variable results. 6. Overall incidence of complication was 20.0%, consisted with two cases of conservatively treated but not accurately reduced type II fractures, a conservatively treated type III fracture, a triplane fracture, and the others.

PURPOSE: Recent studies have revealed close relationships between hepatic injury, metabolic pathways, and gut microbiota. The microorganisms in the intestine also cause irritable bowel syndrome (IBS). The aim of this study was to examine whether IBS was associated with elevated hepatic enzyme [alanine aminotransferase (ALT) and aspartate aminotransferase (AST)], gamma-glutamyl transferase (gamma-GT) levels, and metabolic syndrome (MS). MATERIALS AND METHODS: This was a retrospective, cross-sectional, case-control study. The case and control groups comprised subjects who visited our health promotion center for general check-ups from June 2010 to December 2010. Of the 1127 initially screened subjects, 83 had IBS according to the Rome III criteria. The control group consisted of 260 age- and sex-matched subjects without IBS who visited our health promotion center during the same period. RESULTS: Compared to control subjects, patients with IBS showed significantly higher values of anthropometric parameters (body mass index, waist circumference), liver enzymes, gamma-GT, and lipid levels. The prevalences of elevated ALT (16.9% vs. 7.7%; p=0.015) and gamma-GT (24.1% vs. 11.5%; p=0.037) levels were significantly higher in patients with IBS than in control subjects. A statistically significant difference was observed in the prevalence of MS between controls and IBS patients (12.7% vs. 32.5%; p<0.001). The relationships between elevated ALT levels, MS, and IBS remained statistically significant after controlling for potential confounding factors. CONCLUSION: On the basis of our study results, IBS may be an important condition in certain patients with elevated ALT levels and MS.

Congenital melanocytic nevus(CMN) constitute a well-known risk factor in the development of malignant melanoma, but melanoma developing in newborn and infants are extremely rare. We describe a case of proliferating nodules within CMN at the age of 13 months. Like our case it is difficult to manage the proliferating lesions within CMN in infants. So we carefully suggest the indications of preventive excision when proliferating lesions occur within CMN as follows; 1) preventive excision is postponed until the age of two when the proliferating lesions are slowly growing, 2) surgical excision is needed when the lesions are rapidly growing exceeding 1 cm in size even though it is before the age of two.

8.Marginal Recurrence after Radiofrequency Ablation of Hepatocellular Carcinoma: Relationship between Distance from Hepatic Capsule to Tumor and Recurrence Period.
Journal of the Korean Radiological Society 2003;48(2):171-176
PURPOSE: To examine the relationship between distance from hepatic capsule to tumor and recurrence among hepatocellular carcinoma patients in whom marginal recurrence was noted after radiofrequency ablation therapy. MATERIALS AND METHODS: Between January 2000 and December 2001, hepatocellular carcinoma patients with a tumor 5 cm or less in size and located 2 cm or less from the hepatic capsule underwent radiofrequency ablation therapy. We subsequently selected 37 patients (41 tumors) in whom immediate CT demonstrated complete tumor ablation and follow-up CT showed marginal recurrence. Tumors were grouped according to their distance from the hepatic capsule: Group I, adhered to the capsule; Group II, less than 1 cm from it; Group III, 1-2 cm distant. Of the 41 tumors, 22 were assigned to Group I, six to Group II, and 13 to Group III. Mean tumor size was 3.2 cm, and inter-group variation was small (Group I, 3.3 cm; Group II, 2.9 cm; Group III, 3.1 cm). Follow-up CT was used to determine marginal recurrence, and for inter-group comparison and the assessment of statistical significance, the t test was employed. RESULTS: Marginal recurrence was noted at mean 5.5 months (2.7 months in Group I, 3.0 months in Group II, and 10.5 months in Group III). The t test revealed significant difference between Group I and III (p<0.0001) but not between Groups I and II, or II and III. If '1 cm from hepatic capsule' was the criterion for classification, and Group I and II were combined and compared with Group III, there was significant difference between the two groups (<0.0001). CONCLUSION: Tumors which adhered to the hepatic capsule or were less than 1 cm from it recurred sooner than those situated 1-2 cm away.

Zinc oxide nanoparticles (ZnO NPs) and titanium dioxide nanoparticles (TiO2 NPs) are well known as photoreactive nanoparticles (NPs). Various phototoxicities of ZnO NPs and TiO₂ NPs were reported on several organisms. It was still necessary to evaluate the toxicity of photoreactive ZnO NPs and TiO₂ NPs due to species-specific effects under various irradiation conditions. We compared the acute toxicity of Moina macrocopa under visible, ultraviolet (UV) A, and B irradiations, according to the Organization for Economic Cooperation and Development guidelines for the testing of chemicals (Test No. 202). The sensitivity of ZnO NPs for M. macrocopa was UVB>UVA>visible light irradiation. There were no significant lethal and immobile effects of TiO₂ NPs on juveniles under all irradiations and in the tested concentrations of TiO₂ NPs. Photoreactive NPs have a potential and accelerated toxicity on organisms in the ambient environments.

Chondroid syringoma is a rare primary skin tumor arising from eccrine sweat gland. In 1982, Nasse had found a primary skin tumor having similar morphology as in the mixed tumor of the salivary glands. In 1961, Hirsch and Helwig proposed more descriptive diagnostic term, "Choindroid syringma". The authors experienced two cases of chondroid syringma. The first case was a 47 year old male patient who had had a subcutaneous nodule in the right forehead for two months. It was a well circumscribed mass, that showed tan gray myxoid cut surface with firm consistency. Microscopically, it was a wel diagnosed as chondroid syringoma with tubular, branching lumina. The second case was a 51 year old female patient who had had a subcutaneous nodule in the left forehead for 3 months. It was well circumscribed, ad easily shelled out. It had a typical microscopic features of chondroid syringoma with small, tubular lumina.
