BACKGROUND: There are a few methods, including primary intention, deleyed primary closure and secondary intention, to irpair several types of defects. But commonly-used primary intentional repair of a defect after surgical removal of a skin cancer by graft, flap or simple closure has several limitations such as the need of a skillful technique and various complications. OBJECTIVE: We undertook a secondary intention using occlusive dressing with a polyurethane film after skin cancer surgery instead of a primary repair and evaluated its efficacy, particularly in points of simplicity and safety, and cosmetic results. METHODS: We randomly chose 14 cases of skin cancers in 13 patients who had undergone simple surgical excision or Mohs micrographic surgery and then undertook secondary intention with polyurethane film after informed consent. Postsurgical wound care included cleansing with normal saline or boric acid, then covering the defect with antibiotic ointment, gauze and film a at regular intervals.

The t(3;21) (q26;q22) is associated with chronic myelogenous leukemia in blast crisis, leukemia evolving from therapy-related myelodysplasia, and with leukemia following other hematopoietic proliferative diseases. The t(3;21) is rare secondary aberration in blast crisis of Philadelphia(Ph)-positive chronic myeloid leukemia, which may be restricted to patients entering myeloid blast crisis. We report here in one case of chronic myeloid leukemia in blast crisis which reveals both t(9;22) (q34;q11), and t(3;21) (q26 ;q22). A 62-year-old male was diagnosed as chronic myeloid leukemia 5 years ago, received hydroxyurea therapy, and admitted because of gingival bleeding and fever. On examination, splenomegaly and leukocytosis with proliferated blasts(91%) in peripheral blood were noted. Bone marrow aspirate showed hypercellularity with severe blast proliferation(92.5%) which revealed all negative in peroxidase and PAS stain. Cytogenetic study of bone marrow cells showed the karyotype 46, XY, t(3;21) (q26;q22), t(9;22) (q34;q11), which might be suspected as myeloid blast crisis. Above finding was confirmed by the result of immunophenotyping(CD13 43.6%, CD34 68.2%, HLA-DR 91.6%). He received intensive chemotherapy, but still sustained proliferation of blasts was noted . The follow up cytogenetic study was as follows: 46, XY, 4(3;21) (q26:22), t(9;22) (q34;q11)/46, XY, t(3;21)(q26;q22), del(8) (q22), t(9:22) (q34,q11)/46, XY (16/3/1). He died soon from severe pancytopenia and sepsis.

A rare case of traumatic bilateral anterior and posterior dislocstions of the hip wss occured by autamobile accident as a passenger injury. The right hip was dislocated anteroinferior to the righ scetabulum(neer the right obturator froamen), and the left hip was dislocated posterosuperior to the left acetsbulum with a ipsilateral femur head fracture caudsd to the fovea centralis(Fig. 1).

Background: This study compared and analyzed various concentrations of mesoporous bioactive glass (MBG) gel, commercialacidulated phosphate fluoride gel (APF-gel), and Tooth MousseTM (TM) to evaluate the enamel remineralization effect of early dental caries. Methods: The samples prepared using sound bovine teeth were subjected to MBG gel, APF-gel, and TM to measure changes insurface hardness (Vickers hardness number, VHN) and fluorescence loss values compared to those of sound teeth (ΔF).Repeated measures analysis of variance (ANOVA), Friedman’s ANOVA, Wilcoxon signed-rank test, one-way ANOVA, and Kruskal-Wallis test were used for statistical analysis. Results: The VHN was significantly increased after the two treatments compared to the initial VHN in all other groups, with theexception of the APF gel group (p＜0.05). Compared to the initial ΔF, the APF-gel group significantly decreased ΔF after two treatments, and the remaining groups exhibited significantly increased ΔF (p＜0.05). The MBG group exhibited significantly higher ΔF values than those of the APF gel and TM groups (p＜0.05). Conclusion The MBG group exerted a significantly higher remineralization effect than that of the APF gel group and exhibited asimilar or slightly higher remineralization effect compared to that of the TM group.

PURPOSE: To describe CT findings and differential points of cystic thymic lesions. MATERIAL AND METHOD: We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. RESULTS: All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n=2), thick internal septa and calcifications(n=l). The cysts of teratomas manifested thick walls(n=9), internal septa(n=4), calcifications(n=6), fat components(n=4), and solid components(n=4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. CONCLUSION: The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, .and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

Body fluid Lactate dehydrogenase and its isoenzyme Measurement was performed in 132 patients: 8 cases with peritonitis, 21 cases with malignant ascites, 43 cases with liver cirrhosis, 48 cases with tuberculous pleuritis, 12 cases with malignant pleural effusion respectively. Body fluid protein and glucose contents, red blood cell counts, white blood cell counts, cytologic examination were also performed as a comparative study. The results were as follows: 1. Measurement of total LD and protein amount could differentiate between transudate and exudates in the ascitic fluids. 2. In the malignant exudate of ascites and pleural fluid, the activity of LD2 isoenzyme was statistically increased compared with that of inflammatory exudates and the activity of LD4 isoenzyme was also incereased compared with that of serum (P<0.05). 3. The inflammatory exudates of pleural fluid and ascites demonstrated the increase of LD5 isoenzyme activity statistically compared with that of serum and malignant exudates (P<0.05). 4. A difference of total LD activity between malignant ascites and inflammatory ascites was significant statistically, while this was not observed in the pleural exudate. 5. Total LD and LD5 isoenzyme activity didn't correlated with the number of white blood cells in the exudate.
