It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.

Fifteen patients with 38 compression fractures of the spine underwent magnetic resonance(MR) imaging. We retrospectively evaluated MR images in these benign compression fractures. MR images showed four patterns in T1-weighted images. MR imaging patterns were normal signal(21), band like low signal(8), low signal with preservation of peripheral portion of the body(8), and diffuse low signal through the vertebral body(1). The low signal portions were changed to high signal intensities in T2-weighted images. In 7 of 15 patients(11 compression fractures). There was a history of trauma, and the remaining 8 patients(27 compression fractures) had no history of trauma. Benign compression fractures of trauma, remained 8 patients(27 compression fractures) were non-traumatic. Benign compression fractures of the spine reveal variable signal intensities in MR imagings. These patterns of benign compression fractures may be useful in interpretation of MR imagings of the spine.

S100A6 (calcyclin) is a member of the S100 family and has been originally isolated from the cDNA library of Syrian baby hamster kidney cells. The S100A6 gene expression is reported to remain high throughout the cell cycle following induction by serum or growth factors, suggesting that the gene may be required for cell cycle progression. Nevertheless, the role that S100A6 may play in tumor progression remains unknown. In this study, we have explored the expression patterns of S100A6 gene in human thyroid tissues by northern blot analysis. Using the S100A6 monoclonal antibody, we carried out the immunohistochemical staining to determine the distribution/localization of S100A6 protein within tumor or non-tumorous cells of the thyroid. To modulate the regulation of endogenously expressed S100A6 protein in the intracellular level, overexpressed or anti-sense treated transfectant was constructed by using the eukaryotic expression vector. As a result, immunohistochemistry for S100A6 showed a strong positivity in the malignant tumors of thyroid and a high expression level of S100A6 protein affected cell proliferation in the overexpressed transfectant. These findings suggest that S100A6 may be involved in the tumor pathogenesis and provides another parameter for the differentiation of malignant and benign lesions. A well defined monoclonal antibody against S100A6 protein is now available for the immunohistochemical studies of the various thyroid tissues.

PURPOSE: The purpose of this study is to evaluate the incidence and the degree of peritumoral edema on MRI in meningioma and to correlate other MR findings with the edema. MATERIALS AND METHODS: MR images of 35 patients with histologically-confirmeal meningioma were retrospectively reviewed. We analyzed the MR findings with special attention to the presence or absence and degree of edema. The edema was graded as absent, mild (extending less than 1 cm from outer margin of mass), moderate (1 to 3cm with mild mass effect), and severe (more than 3cm with marked mass effect). We also evaluated size and margin of the tumor, heterogeneity of mass signal, enhancement pattern and dural enhancement of the masses. In 24 patients with cerebral angiography, cerebral vascularity on angiogram was correlated with MR findings. Statistic correlation analysis was done using SAS ver 6.04. RESULTS: Twenty-five of 35 cases (72%) had edema; mild in 11 cases, moderate in 10 cases, and severe in 4 cases. Heterogeneous signal intensity of mass (<0.001), heterogeneous enhancement of mass (<0.001), mass size (<0.001), location (<0.001), and vascularity on angiography (<0.05) were well correlated with edema, while mass margin (>0.05), dural enhancement (>0.05), and histologic type (>0.05) were not correlated with edema. CONCLUSION: In meningioma, moderate to severe peritumoral edema occurred in 41% (14/35). The edema was correlated with heterogeneous enhancement, size, location, heterogeneous signal intensity and vascularity of the mass on angiography.

Lipoma Arborescens is rarely encountered in hip joint. This term was first used by Mueller in 1838, to describe a fatty trmor of the knee which presented branched villous-like projection. The etiology is unknown, Suggests its probable reationship to tuberculosis, rheumatoid arthitis, trauma, chronic inflammation, diabetes mellitus and degenerative arthritis. It frequently involves knee joint, hand, wrist, foot, ankle, tendon sheath and hip joint. It usually presents bilaterally. Their nonspecific symptoms and signs are mild pain, joint swelling with minimum effusion, festriction of joint motion, redness, local heating and crepitus. We experienced a case of lipoma arborescens of hip joint, which was treated by synovectomy with excision of lesion.

The safety, tolerability and immunogenicity of an oral cholera vaccine (OCV) was assessed in adult Korean male through an open-label, non-comparative clinical study. Two doses of vaccine with an interval of 2 weeks were given to 20 healthy subjects. A total of 7 adverse events occurred in 6 subjects. However, no clinically significant change was observed in electrocardiograms, vital signs, physical examinations, and clinical laboratory tests. The immunogenicity of OCV was evaluated by serum vibriocidal assay where anti-Vibrio cholerae O1 and O139 antibodies were measured at day 0, 14, and 28 of vaccine administration. The antibody titers ranged from < 2.5-5,120 for V. cholerae O1 Inaba, < 2.5-10,240 for V. cholerae O1 Ogawa and < 2.5-480 for V. cholerae O139. In addition, the fold increase in antibody titers ranged from 1-4,096 for O1 Inaba, 1-8,192 for O1 Ogawa, and 1-384 for O139. The seroconversion rate was 95% and 45% for O1 and O139 antibodies, respectively. Our study clearly shows that administration of two doses of OCV at a 2 week-interval increases an appropriate level of antibody titer in the serum of healthy Korean adult males (Clinical Trial Number, NCT01707537).
