Objective : This study was conducted to evaluate the relation between symptoms and hippocampal volume in patients with posttraumatic stress disorder (PTSD). Methods : Eight patients with PTSD and five normal controls were enrolled in the present study. The severity of PTSD symptoms was measured using the clinician administered PTSD scale (CAPS), Hamilton Rating Scale for Depression (HAMD), Hamilton Anxiety Rating Scale (HAMA). Magnetic resonance imaging (MRI) was used to measure hippocampal volume. Results : There were significant differences in the CAPS, HAMD, and HAMA scores between the PTSD patients and normal controls. The left and right hippocampal volumes were smaller in the PTSD patients than in the normal controls, but this difference was not statistically significant. The results showed that PTSD symptoms were not related to hippocampal volume. Conclusion : In this study, we could not identify a difference in hippocampal volume between normal controls and patients with PTSD at eight months after trauma. Future research with different subjects and a larger sample size is needed in order to confirm the difference in hippocampal volume.

Objectives: To evaluate the efficacy and safety of induction chemotherapy with docetaxel and cisplatin in locally advanced head and neck cancer. Materials and Methods: Between June 1998 and December 2004, 30 patients were enrolled and among them, 20 patients were evaluable. Patients were treated with docetaxel $75mg/m^2$ and cisplatin $60mg/m^2$ on day 1 every 21 days. Results: The median age was 71(range 54-80) years old. All 20 patients were male. Nineteen patients had pathologically squamous cell carcinoma and 1 had undifferentiated carcinoma. Fourteen of 20 patients(70%) demonstrated an objective response with two(10%) achieving a complete clinical response and eleven(60%) a partial response. The median response duration was 5.3(1.6-32.1) months and the median time to progression was 5.6(1.4-33.8) months. The median overall survival of all patients was 14(range 2.2-34) months. The median overall survival of responders was 17.5(range 5-34) months and that of non-responders was 3.2(range 2.2-23) months, but it was not statistically significant(p=0.106). During a total of 92 cycles, granulocytopenia worse than CTC(Common toxicity criteria) grade 2 occurred in 6%, thrombocytopenia in 2%, and anemia in 3%, respectively. Non-hematologic toxicities were minor and easily controlled. Conclusion: The induction chemotherapy of docetaxel and cisplatin has moderate efficacy with acceptable toxicities in patients with locally advanced head and neck cancer.

Primary mediastinal nonseminomatous germ cell tumor associated with Klinefelter's syndrome is a rare disorder. We experienced a case of recurred primary mediastinal nonseminomatous germ cell tumor developed in a 24-year-old patient with Klinefelter's syndrome. The patient had been treated with surgery and combination chemotherapy under the diagnosis of primary mediastinal nonseminomatous germ cell tumor before. A round mass was found on the right lower lung field in the chest X-ray during follow up. The patient was diagnosed as recurred primary nonseminomatous genu cell tumor and Klinefelter's syndrome through tumor markers, peripheral blood karyotyping, and other tests including hormonal assay and was treated with combination chemotherapy and surgery again. When the patient is diagnosed as primary mediastinal nonseminomatous germ cell tumor, Klinefelter's syndrome and hematologic malignancies should be considered to be associated diseases and vice versa.

Objectives : Among the patients at Seoul Veterans Hospital, there is a great demand for oriental medical treatments, and the number of patients of oriental medical part is on the increase. The purpose of this study is to show patients inclination statistically. Methods : The study was carried out on the 1045 patients came to Seoul veterans hospital from April 2003 to May 2004. Results & Conclusions : 1. Most of men patients were veterans. They had neurological disorder or cerebrovascular disease that was ongoing for 1~5 years before diagnosis and they were treated less than 10 times. 2. Most of women patients were nursing their family. They had musculoskeletal disease that was ongoing 1 week before diagnosis and they were treated less than 10 times. 3. Under the current system, only acupuncture and other limited treatments are provided to patients due to the limited funding from the government. There were few patients who had an internal disease because they needed to be herbal treated. If the government funding were provided, they would be able to be treated.

When the old schwannoma has the degenerative changes, it is named as the ancient schwannoma which was rarely reported. The degenerative changes are perivascular hyalinization, calcification, cystic necrosis, marked decrease of Antoni type A area, and degenerative nuclei and the ancient schwannoma may be misinterpreted as sarcomatous pleomorphisms. We experienced the ancient schwannoma which has massive hemorrhage and hematoma, cystic change, calcification, and marked decrease of Antoni A area in leg on 75 year old male patient, and report it.

To evaluate the role of hepatobiliary (DISIDA) scan in the diagnosis of biliary obstruction, we studied the clinical characteristics of 9 cases with biliary obstructuon, whose hepatobiliary scans and ultrasonography were not concordant (normal ultrasonography and abnormal hepatobiliary scan). The results were as follows; 1) The main chief complaints (89%) were abdominal pain, especially in RUQ area. The levels of serum bilirubin were elevated in 67% of patients $(normal\sim5.9mg/dl)$ and those of alkaline phosphatase were elevated in 78% of patients $(normal\sim724U/L)$. 2) The final diagnoses were CBD stones (67%), tumor (22%) and 3 cases were associated with C. sinensis. 3) The major obstruction sites were in distal CBD (89%). From the above results we concluded that hepatobiliary scan is a useful diagnostic method of biliary obstruction, especially in distal CBD lesion and early stage, in spite of normal ultrasonography.

We have experienced a case of comparatively rare anteromedial meniscofemoral ligament (AMMFL) in which the anterior horn of the medial meniscus was attached to the posterolateral wall of the femoral intercondylar fossa. AMMFL was diagnosed and confirmed during therapeutic arthroscopy. The report suggests the need for increased awareness of the possible presence of this. Additionally, we illustrate the anomaly, discuss its controversial clinical significance and review the literature.

We report a case of an 85-year-old woman with tuberculous subdeltoid bursitis. Tubeculous bursitis without adjacent joint tuberculosis may occur any site but it is rare. It is common in bursae subjected to trauma like trochanteric, prepatellar, olecranon and so on. Because the clinical findings or physical examination of tuberculous subdeltoid bursitis are similar to rotator cuff disorder and the MRI or arthroscopic findings are similar to synovial diseases, careful differential diagnosis is necessary.

A case of nonsecretory multiple myeloma in a 66 year-old-woman is reported. At first, she complained severe neck pain and radiologic finding showed C2 pathologic fracture. She complained severe low back pain 4 month later and L1 compression fracture was found. The lumbar MRI showed a 1.4cm-sized round enhancing lesion in the body of T12. Bone marrow aspiration biopsy at L1 spine showed a few polymorphous and small nests of mononuclear cell. L1 lamina bone biopsy showed many abnormal plasma cells. Pathologic diagnosis was multiple myeloma. However, plasma electrophoresis and protein immunoelectrophoresis of serum and urine of patient were normal. So, it is a nonecretory multiple myeloma case and the incidence of nonsecretory multiple myeloma is known to about 1% of all multiple myeloma.

Radiological properties of newly introduced and existing 3-dimensional (3D) printing materials were evaluated by measuring their Hounsfield units (HUs) at varying infill densities. The six materials for 3D printing which consisted of acrylonitrile butadiene styrene (ABS), a unique ABS plastic blend manufactured by Zortrax (ULTRAT), high impact polystyrene (HIPS), polyethylene terephthalate glycol (PETG), polylactic acid (PLA), and a thermoplastic polyester elastomer manufactured by Zortrax (FLEX) were used. We used computed tomography (CT) imaging to determine the HU values of each material, and thus assess its suitability for various applications in radiation oncology. We found that several material and infill density combinations resembled the HU values of fat, soft tissues, and lungs; however, none of the tested materials exhibited HU values similar to that of bone. These results will help researchers and clinicians develop more appropriate instruments for improving the quality of radiation therapy. Using optimized infill densities will help improve the quality of radiation therapy by producing customized instruments for each field of radiation therapy.
