Primary non-Hodgkin's lymphoma of the lung is rare among extranodal lymphomas. The most common form is low grade B-cell type originated from the mucosa-associated lymphoid tissue (MALT) of the lung and primary peripheral T cell lymphoma of the lung is extremely rare. We recently experienced a case of fine needle aspiration cytology of primary peripheral T cell lymphoma of the lung in a 39-year-old male patient. The cytologic smears revealed some sheets of reactive epithelial cells, epithelioid histiocytes, and numerous polymorphous population of lymphoid cells composed of small and intermediate sized lymphoid cells and mature lymphocytes. Lymphoid cells were slightly larger than normal mature lymphocytes and showed significant irregularity of nuclear membrane. The internal nuclear structure was marked by chromatin clumping, clear parachromatin areas, and inconspicuous nucleoli. Histopathologically, atypical small lymphocytes infiltrated in the interstitium and alveolar sac. By the immunohistochemical study and molecular biologic study of gene rearrangement, the T cell clonality of atypical lymphoid cells was confirmed. Key words: Peripheral T cell lymphoma, Lung, FNAC

Objective To explore the possibility of three-dimensional orbit replications for clinic and teaching of orbital blowout fracture surgical operation.Methods The orbital CT DICOM format data from 10 patients with orbital floor fractures were selected between November 2016 and January 2017 from Wendeng Osteopath Hospital.Thresholding technique,region growing technique,edit mask technique and multiple slice edit technique were used in sequence by Mimics software.And 3D replications were printed by Object 500 3D printer.The sizes of the replications were measured.The model of orbital blowout fracture and surgical implant model were simulated by senior orbital surgeon.Results In the 10 cases,male was 5 cases,and female was 5 eyes.The 3 D replications of the orbits were successfully designed and printed.The sizes of the 3D replications were basically consistent with those of patients' orbits,and there was no statistical difference (all P > O.05).Under operation room surgery simulation environment,the orbital fracture surgical repair operation was demonstrated to the resident by the senior surgeon,3D printing orbital blowout fracture model can be successfully used to simulate the operation and teaching demonstration.Conclusion 3D printing orbital blowout fracture model can restore the true orbital injury and orbital anatomic details,provides the design operation of stereoscopic model for the physician,which has positive significance to understand the scope and surgery teaching simulation of orbital blowout fracture.

Angiogenesis is an essential process in tumor growth and metastasis. VEGF has been considered a leading candidate inducing tumor angiogenesis. VEGF expression was significantly correlated with clinical stage, lymph node matastasis, and prognosis of cancers of various parts of body. However, little has been known about the correlation between VEGF expression and clinicopathologic parameters in oral squamous cell carcinoma. The aim of this study was to correlate VEGF expression with the clinicopathological parameters and microvessel density. Forty six oral squamous cell carcinomas were analyzed using immunohistochemical method with primary antibodies to VEGF and CD31. VEGF expression was detected in 33 (71.7%) of the 46 cases. The microvessel density was significantly correlated with VEGF expression (P=0.002). There was no correlation between microvessel density and tumour size, clinical stage, and lymph node metastasis, respectively. VEGF expression did not correlate with the histological grade of tumour differentiation, tumour size, and clinical stages. The VEGF-positive rate seemed to be higher in patients with cervical lymph nodal metastasis than in those without it, but it was not statistically significant. In conclusion, the overexpression of VEGF in the oral squamous cell carcinoma seemed to be associated with a more aggressive course of the disease. Further study is necessary to define the role of VEGF in oral squamous cell carcinoma.

PURPOSE: We aimed to identify a more esthetic width-to-length ratio by analyzing maxillary central incisor of Korean adult population. Information regarding tooth ratio in the Korean population may be useful to clinicians when restoring anterior teeth. MATERIALS AND METHODS: A total of 40 men and 40 women were included in this study. The NON-MEDIA group included 40 non-celebrities, who were healthy and 25 to 39 years old, with normal dentofacial appearance. The MEDIA group consisted of 40 celebrities selected only on the basis of their soft-tissue facial appearance. The facial photographs of 40 celebrities were collected from the Internet websites. The width and length of the maxillary central incisor were measured using Adobe Photoshop(R) 7.0, a software for analysis, measurement and edition of photographs. Data were analyzed statistically using the Independent t-test at 5% statistical significance level. RESULTS: The mean ratio for the MEDIA group was 0.77, whereas that of the NON-MEDIA group was 0.88. The difference between the two groups was statistically significant. No significant gender differences were found in the width-to-length ratio in MEDIA group. In NON-MEDIA group, however, there were significant differences between female and male. CONCLUSION: After analyzing maxillary anterior teeth of Korean adults, our results were in accordance with the general Western standards of esthetics. A dentist restoring the natural look and beauty of teeth will have to consider those standards.

BACKGROUND: The Multiplate analyzer (Dynabyte GmbH) has been recently introduced as a platelet function test for patients taking antiplatelet drugs. The study aimed at providing basic data for determining the reference interval of parameters produced by Multiplate in Koreans and to study the factors that influence those parameters. METHODS: Blood was collected from 35 healthy volunteers (female 18, male 17) into tubes containing hirudin or 3.2% sodium citrate. Whole blood platelet aggregations triggered by adenosine-5'-diphosphate (ADP), ADP-high sensitive (ADP+PGE1 only in hirudin samples), arachidonic acid (AA), collagen or thrombin receptor activator peptide (TRAP) were investigated using Multiplate according to the manufacturer's instructions. Data from healthy volunteers for the area under the curve (AUC) were determined from the central 95th percentile of the results. RESULTS: The values of AUC in hirudin samples for all agonists were significantly higher than those in sodium citrate samples. The AUC values in hirudin (sodium citrate) samples were as follows: ADP 38-107 (18-119) U; ADP+PGE1 16-91 U; AA 64-156 (32-117) U; collagen 53-112 (26-108) U; and TRAP 81-163 (49-149) U. The parameters from Multiplate were significantly correlated with leukocyte counts, but not with hematocrit levels. CONCLUSIONS: Although our data were derived from only 35 subjects, the results are expected to be helpful in determining the reference interval at a single institute and may serve as basic data for future cumulative data of reference intervals from multiple institutes in Korea.
