Focal myositis, a benign myositis which mostly occurs at lower extremity, is a disease that is spontaneously improved by conservative treatments such as bed rest and administration of nonsteroidal anti-inflammatory drug. Focal myositis is known to occur mostly at lower extremity, but we could not find a report of occurrence around hip. Therefore, authors attempt to report clinical progression along with the literature review.

Transforming growth factor-B1 (TGF-B1) is well known to be one of the most potent Immunosuppressive cytokines. To determine whether TGF-B1 secreted in the latent form can be immunoregulatory, TGF-B1 cDNA driven by the human -actin promotor was transfected into a murine thymoma cell line, EL4 cells. The transfectants (ELJ4) secreted a latent torm of TGF-B1 at a concentration of 5 ng/ml under the influence of TPA. Transfected TGF-b1 transcripts was readily detected by RT-PCR in ELJ4 cells regardless of the presence of TPA, but not in EL4 cells. In addition, we found the degree of Thy-B1 expression, IL-2 secretion and the proliferation rate are not altered by the transfection. Finally, EL4 and ELJ4 cells were injected into C57BU6 mice (syngenic strain), subcutaneously. Tumor cell masses derived from both cell populations survived longer than 1 wk, and the size of tumor derived from ELJ4 was three times larger (2.5 cm of diameter) than that from EL4. Virtually, there was no histopathological difference between two tumors. Taken together, the results from the present study indicates that EL4 thymomas transfected with TGF-1 secretes a latent form of TGF-B1 which may suppress host immune defence system.

OBJECTIVE: To determine clinical and radiological factors that predict the successful outcome of percutaneous disc decompression (PDD) in patients with lumbar herniated nucleus pulposus (HNP). METHODS: We retrospectively reviewed the clinical and radiological features of patients who underwent lumbar PDD from April 2009 to March 2013. Sixty-nine patients with lumbar HNP were studied. Clinical outcome was assessed by the visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Multivariate logistic regression analysis was performed to assess relationship among clinical and radiological factors and the successful outcome of the PDD. RESULTS: The VAS and the ODI decreased significantly at 1 year follow-up (p<0.01). One year after PDD, the reduction of the VAS (DeltaVAS) was significantly greater in the patients with pain for <6 months (p=0.03) and subarticular HNP (p=0.015). The reduction of the ODI (DeltaODI) was significantly greater in the patients with high intensity zone (p=0.04). Multivariate logistic regression analysis revealed the following 5 factors that were associated with the successful outcome after PDD: pain duration for <6 months (odds ratio [OR]=14.036; p=0.006), positive straight leg raising test (OR=8.425, p=0.014), the extruded HNP (OR=0.106, p=0.04), the sequestrated HNP (OR=0.037, p=0.026), and the subarticular HNP (OR=10.876, p=0.012). CONCLUSION: PDD provided significant improvement of pain and disability of patients. The results of the analysis indicated that the duration of pain <6 months, positive straight leg raising test, the subarticular HNP, and the protruded HNP were predicting factors associated with the successful response of PDD in patients with lumbar HNP.

OBJECTIVE: To evaluate the clinical efficacy and safety following percutaneous disc decompression, using navigable disc decompression device for cervical herniated nucleus pulposus (HNP). METHODS: Twenty subjects diagnosed with cervical HNP and refractory to conservative management were enrolled for the study. The herniated discs were decompressed under fluoroscopic guidance, using radiofrequency ablation device with navigable wand. The sagittal and axial plain magnetic resonance images of the clinically significant herniated disc, decided the space between the herniated base and outline as the target area for ablation. Clinical outcome was determined by Numeric Rating Scale (NRS), Neck Disability Index (NDI), and Bodily Pain scale of Short Form-36 (SF-36 BP), assessed after 48 weeks. After the procedure, we structurally matched the magnetic resonance imaging (MRI) and C-arm images through bony markers. The wand position was defined as being ‘correct’ if the tip was placed within the target area of both AP and lateral views; if not, the position was stated as ‘incorrect’. RESULTS: The average NRS fell from 7 to 1 at 48 weeks post procedure (p<0.05). In addition, statistically significant improvement was noted in the NDI and SF-36BP (p<0.05). The location of the wand tip resulted in 16 correct and 4 incorrect placements. Post-48 weeks, 3 of the incorrect tip cases and 1 correct tip case showed unsuccessful outcomes. CONCLUSION: The study demonstrated the promising results and safety of the procedure. Thus, focal plasma ablation of cervical HNP with navigable wand can be another effective treatment option.

Axillary disorders originate from an axillary lymph node, subcutaneous fat layer, accessory breast, nerve, vessel and muscle. The most common causes of a palpable axillary mass are a lymph node pathology containing a benign axillary lymphadenopathy, and malignant lymph nodes such as a metastatic lymphadenopathy from breast cancer and a malignant lymphoma. For the detection of masses in the axilla, mammography and sonography are the imaging modalities of choice. We present a spectrum of various axillary masses with correlative radiological imaging and pathological findings in this pictorial essay. Knowledge of the radiological findings of various axillary disorders is useful for a differential diagnosis and for preventing unnecessary invasive procedures.

Propylthiouracil(PUT) is a drug which used at Grave's disease. But PTU has recently been observed to associated with antineutrophil cytoplasmic antibody(ANCA)-positive vasculitis resulting in, infrequently, diffuse alveolar he?morrhage. We report the case of a patient who developed diffuse pulmonary hemorrhage after she had been taking PTU for two years. She had received a diagnosis of Grave's disease at two years ago. The serologic study was positive for ANCA with myeloperoxidase(MPO) specificity. Bronchoalveloar lavage(BAL) fluid analysis revealed hemosiderin- laden macrophages. Such findings suggested propylthiouracil?induced dffuse pulmonary hemorrhage associated with antineutrophil cytoplasmic antibody. To our knowledge, this represents the first documentation in a case of PTU-induced diffuse pulmonary hemorrhage in Korea.

BACKGROUND: Chronic obstructive lung disease is characterized by smoke-related, gradually progressive, fixed airflow obstructions. However, some studies suggested that a reversible bronchial obstruction is common in chronic obstructive lung disease. Such reversibility persists despite the continued treatment with aerosolized bronchodilators and it appears to be related to the diminution in symptoms. The isolated volume response to a bronchodilator is defined as a remarkable increase in the FVC in response to the administration of a bronchodilator whereas the FEV1 remains unchanged. This has been suggested in patients with severe emphysema. Therefore, the aim of this study was to determine the relationship between the response to a bronchodilator and the severity of an airflow obstruction in COPD patients using the GOLD classification. METHODS: This study examined 124 patients with an airway obstruction. The patients underwent spirometry, and the severity of the airflow obstruction was classified by GOLD. The response groups were categorized by an improvement in the FVC or FEV1 > 12%, and each group was analyzed. RESULTS: Most subjects were men with a mean age of 65.9+/-8.5 years. The mean smoking history was 41.26+/-20.1 pack years. The isolated volume response group had relatively low FEV1 and FVC values compared with the other groups. (p<0.001) CONCLUSION: In this study, an isolated volume response to a bronchodilator is a characteristic of a severe airway obstruction, which is observed in patient with a relatively poorer baseline lung function.

Primary pulmonary non-Hodgkin's lymphoma (NHL) account for 0.4% of all types of lymphoma. Most cases are of the mucosa-associated lymphoid tissue (MALT) type, low grade B-cell lymphoma, but cases of the T-cell type are rare. The radiological findings frequently show hilar or mediastinal lymphadenopathy, but lung parenchymal involvement is uncommon. Here, a case of a patient, who presented with fever, generalized erythema, diffuse pulmonary infiltration and pleural effusion, diagnosed as a peripheral T-cell lymphoma, is reported.
