Analysis of scars in various conditions is essential, but no consensus had been reached on the scar assessment scale to select for a given condition. We reviewed papers to determine the scar assessment scale selected depending on the scar condition and treatment method. We searched PubMed for articles published since 2000 with the contents of the scar evaluation using a scar assessment scale with a Journal Citation Report impact factor >0.5. Among them, 96 articles that conducted a scar evaluation using a scar assessment scale were reviewed and analyzed. The scar assessment scales were identified and organized by various criteria. Among the types of scar assessment scales, the Patient and Observer Scar Assessment Scale (POSAS) was found to be the most frequently used scale. As for the assessment of newly developed operative scars, the POSAS was most used. Meanwhile, for categories depending on the treatment methods for preexisting scars, the Vancouver Scar Scale (VSS) was used in 6 studies following a laser treatment, the POSAS was used in 7 studies following surgical treatment, and the POSAS was used in 7 studies following a conservative treatment. Within the 12 categories of scar status, the VSS showed the highest frequency in 6 categories and the POSAS showed the highest frequency in the other 6 categories. According to our reviews, the POSAS and VSS are the most frequently used scar assessment scales. In the future, an optimal, universal scar scoring system is needed in order to better evaluate and treat pathologic scarring.

Computerized tomography has been used in the evaluation of the intracranial lesions. Recently the usage of computerized tomography has progressively widened in many fields of clinical practice. In orthopedics computerized tomography has been tried in the diagnosis and the determination of treatment of tumors, spinal disorders, hip disorders and knee problem. Four problem cases in which concentric reduction could not be obtained after closed reduction of hip dislocations were evaluated by computerized tomography from Apr, 1, 1983 to Mar. 31, 1984 in the Capital Armed Forces General Hospital and following conclusiions were obtained: 1. Open reduction revealed that muscles(adductor and pyriformis muscles), joint capsule and osteocartilaginous loose bodies (femoral and acetabular) were interposed to hinder concentric reduction. Large posterior acetabular fragment induced instability and redislocation of the hip. 2. When there were 2-3 mm lack of symmetry of the two femoral heads or any abnormal findings(breakage of Shenton's line etc.) in plain roentgenography, computerized tomography was recommanded, and muscles, osteocartilaginous loose bodies and instability were found. 3. Computerized tomography is an easy simple method and has a great diagnostic value in the evaluation of asymmetry and instability after closed reduction of traumatic hip dislocations.

Conventional abdominoplasty includes the removal of an ellipse-shaped section of abdominal tissue between the umbilicus and mons pubis. However, this method can result in tension of the undermined flap, especially in the midline. To address this problem, we present reverse lip design as a modified method that also has aesthetic advantages. The reverse lip design entails a longer lower flap edge while preserving the triangular tissue in the vascularly stable pubis area. These markings create an image of a reverse lip shape with a cleft at the bottom of the lower markings. After typical lipoabdominoplasty is performed, redundant waist tissues can easily be pulled inward and downward. The reverse lip design abdominoplasty demonstrated no complications and required no further revisions after the procedure. Patients were generally satisfied with the aesthetic improvements in their body shape. They were also able to return to their routine activities approximately 1 week after the operation while wearing a supporting undergarment. This modified abdominoplasty using the reverse lip design reduces low midline tension of the undermined abdominal flap while enhancing body aesthetics with a slimmer waistline, leading to higher patient satisfaction.

We evaluated the antibacterial, anti-inflammatory, and inhibitory effect of osteoclast differentiation of Brachypodium sylvaticum (BS) to find out the possibility of preventing periodontal disease. The inhibition of Porphyromonas gingivalis (P. gingivalis) growth by BS and the sustainability of the antibacterial activity was assessed. The production of pro-inflammatory cytokines from lipopolysaccharide (LPS)-induced RAW 264.7 cells were measured using enzyme-linked immunosorbent assays (ELISA), and the production of nitric oxide (NO) and cell viability were measured. Osteoclast differentiation was evaluated by Tartrate-resistant acid phosphatase (TRAP) staining, and TRAP activity. BS showed significant antibacterial activity and sustainable antibacterial activity in P. gingivalis. We also found out that the BS significantly decreased secretion of pro-inflammatory cytokines [tumor necrosis factor (TNF-α) and interleukin-6 (IL-6)] and NO production without cytotoxicity. Furthermore, BS inhibited the differentiation of bone marrow macrophages (BMMs) obtained from mouse bone marrow cells into osteoclasts without cytotoxicity. Taken together, BS can be a promising candidate for a preventive and improving agent of periodontal disease having antibacterial, anti-inflammatory, and inhibitory effects of osteoclast differentiation.

During the treatment of cancers, especially with anticancer drugs, the recurrence of cancer is the most important factor for survival rate. The most common cause of the recurrence is the resistance of cells to anticancer drugs. To explore and analyze the changes of gene expression during the induction of resistance by anticancer drugs in human osteogenic cancer cell line Saos-2. The drug resistance was induced with adriamycin, cisplatin or vincristine at 10(-7) M concentration of each and cDNA microarray was performed. Total RNA was purified from Saos-2, adriamycin-resistant (Saos-2AdR), cisplatin-resistant (Saos-2CpR) and vincristine-resistant (Saos-2VcR) and expressed genes were investigated with a Affymetrix Human HG-U133Plus2.0 GeneChip(TM). The genes of anticancer drug resistant cells that showed more than 2.5 fold expression change than Saos-2 were selected for differential expression. Four hundred seventeen genes were selected for Saos-2 vs Saos-2AdR. Two thousand five hundred thirty six genes were selected for Saos-2 vs Saos-2CpR. Two hundred twenty five genes were selected for Saos-2 vs Saos-2VcR. Eighty seven genes were selected for common differential expression. The results showed that many genes were changed in expression during the acquiring of resistance to anticancer drugs but most of genes were not in common among the three anticancer durg-resistant Saos-2. This means the different anticancer drug takes the different mechanism for acquiring resistance to anticancer drug even we use same cells.

The Kallmanns syndrome is the most common form of isolated hypogonadotropic hypogonadism in which anosmia or hyposmia resulting from agenesis of hypoplasia of the olfactory lobes is associated with LHRH deficiency, This syndrome is genetically heterogeneous and can be trans-mitted as an X-linked, autosomal dominant or autosomal recessive trait. The hypogonadotropic hypogonadism results in absent or incomplete pubertal development and may be associated with anosmia or hyposmia, mid-line defect(color blindness, cleft-lip or

PURPOSE: Extra-thyroidal extension has been recognized as a poor prognostic factor for increased regional recurrence risk in papillary thyroid carcinoma, and is known to require treatment that is more aggressive. In the recent UICC TNM 6th Classification, an extra-thyroidal extension was divided into a minimal extra-thyroidal extension (T3) and a massive extra-thyroidal extension (T4). The aim of this study was to investigate the clinical effect of a minimal extra-thyroidal extension of a papillary carcinoma for the recurrence of regional cervical lymph nodes. METHODS: We retrospectively studied 154 patients with papillary thyroid carcinoma where a thyroidectomy was performed from Feb. 2003 to May. 2006 at the Department of Surgery, with the exclusion of 6 patients with a massive extra-thyroidal extension. We divided the cases into a no extra-thyroidal extension group and a minimal extra-thyroidal extension group according to the grading of the extra-thyroidal extension. The grading of the extra-thyroidal extension was based on both pathological findings and intraoperative surgical findings. Clinicopathological factors associated with each group were analyzed by univariate and multivariate analysis. We divided the cases into two groups according to age (<45 yrs, > or =45 yrs) and lymph node status (positive, negative), and compared each group with regards to disease free survival according to the grading of the extra-thyroidal extension. RESULTS: By univariate analysis, a minimal extra-thyroidal extension was related to lymph node metastasis, tumor size, mutifocality (P<0.05), and was not related to cervical lymph node recurrence statistically (P=0.108). Cervical lymph node recurrence was related to being male, lymph node metastasis and tumor size (P<0.05). By multivariate analysis, a minimal extra-thyroidal extension was independently related to tumor size, multifocality, and lymph node metastasis (P<0.05). In both groups with regards to age and lymph node status, a minimal extra-thyroidal extension was not statistically related to disease free survival (P>0.05). CONCLUSION: We need to downstage to less than T3 for a minimal extra-thyroidal extension because there is no significant difference in disease free survival according to the grading of an extra-thyroidal extension in patients with papillary thyroid carcinoma.
