Kaposi's sarcorna is a tumor-like condition which characterized by a mixed proliferation of fibroblastic components and vascular structures. The authors report a case of nodular type of Kaposis sarcoma in 54 year-old male who had an eroded hemorrhagic nodule and few papular lesions. These lesions involved only both hands and feet without systemic involvement.

Computed Tomograms of 45 patients with or without lung mass were reviewed to determine the characteristics of the major and minor fissures. Also pulmonary vascular distibutions were analyzed to localize each pulmonary lobe. The results were as follows; 1. Each major fissure area was imaged frequently as lucent band, less frequently dense band. 2. The minor fissure areas were imaged as oval or triangular lucent zones. The oval or triangularlucent zones were as same frequency. 3. Avascular planes without above mentioned lucent zones were also correspond to minor fissure areas. 4. Slices of avascular zones were observated between pulmonary arteries to posterior segment or apicoposterior segment of upper lobe and to superior segement of lower lobe on both lungs.

Recovery from potentially lethal damage (PLDR) after irradiation was studied in plateau-phase culture of Vero cells in vitro. Unfed plateau-phase cells were irradiated with dose of 1 to 9 gy using Cs-137 irradiator. Cells then were incubated again and left in situ for 0, 1, 2, 3, 4, 5, 6 and 24 hours and then were trypsinized, explanted, and subcultured in fresh RPMI-1640 media containing 0.33% agar. Cell survival was measured by colony forming ability. An adequate number of heavily irradiated Vero cells were added as feeder cells to make the total cell number constant in every culture dish. As the postirradiation in situ incubation time increased, surviving fraction increased saturation level at 2 to 4 hours after in situ incubation. As the radiation dose increased, the rate of PLDR also increased. In analysis of cell survival curve fitted to the linear-quadratic model, the linear inactivation coefficient (alpha) decreased largely and reached nearly to zero but the quadratic inactivation coefficient (beta) increased minimally by increment of postirradiation in situ incubation time. So PLDR mainly affected the damage expressed as alpha. In the multitarget model, significant change was not obtained in D0 but in Dq. Therefore, shoulder region in cell survival curve was mainly affected by PLDR and terminal slope was not influenced at all. And dose-modifying factor by PLDR was relatively higher in shoulder region, that is, in low dose area below 3 gy.

OBJECTIVES: Visualization of the left atrial appendage(LAA) by the transesophageal echocardiography(TEE) is excellent, but it is difficult to visualize the LAA by the modified parasternal short-axis view(MPSA) in transthoracic echocardiography(TTE). We studied to determine the usefulness of the apical horizontal view(AHV) abtained by the apical rotation method of the transducer for the detection of the LAA. METHODS: We studied the MPSA and AHV in 602 patients, The LAA was observed during diastole of the LAA. We obtained an apical horizontal view by 45 degree clockwise rotation of the transducer from the apical 2 chamber view and compared with the visualization of the LAA in AHV and MPSA. RESULTS: Among 602 patients, LAA could not be visualized in 88(14.6%) because of a poor echo-window. LAA was more clearly visualized in 222 patients by the AHV than the MPSA and 56 patients by the MPSA than the AHV. LAA was same degree visualization in patients by the AHV and MPSA. In male and female, more than 55 ages and less than 55 ages, visualization of inner margin of the LAA by the AHV was more clear than by the MPSA. CONCLUSION: The AHV was a useful, noninvasive and reproducible method for the visualization of the LAA.

Osteoma is defined as a benign neoplasm of bony tissue. Osteomas are divided into two groups: central and peripheral by origin, compact and cancellous by histopathologic findings. Solitary osteoma of jaw bone, not related with Gardner syndrom, is relatively uncommon. We present two cases of huge solitary peripheral osteomas: compact type exophyting osteoma on the inferolingual side of mandibular angle and cancellous type on the residual ridge of posterior maxilla, which is extremely rare.

PURPOSE: To investigate the expression of Vascular Endothelial Growth Factor (VEGF) in diabetic frozen shoulders. MATERIALS AND METHODS: We preformed arthroscopic adhesiolysis on 9 diabetic frozen shoulder patients, and observed the arthroscopic findings. Also, we examined the potential role of VEGF by using samples of synovial tissues from 5 patients, and 2 normal synovial tissues. Immunohistochemical staining and Western blotting were performed using polyclonal antibodies against VEGF. RESULTS: There was hyperemic synovitis in the 9 diabetic frozen shoulder patients. In the 5 patients' tissue samples, there was strong immunostaining and expression to VEGF, but there was little staining and expression in the control group. CONCLUSION: We postulate that VEGF is synthesized and secreted in the synovium of diabetic frozen shoulders and that secreted VEGF binds specific receptors on the endothelial cells of nearby small blood vessels, and leads to the subsequent development of frozen shoulders in diabetic patients.

Cervical epidural steroid injection is frequently used in the conservative management of neck pain and cervical radiculopathy. Epidural cervical transforaminal injections are usually well-tolerated with mild side effects such as transient decreased sensory and motor function, or headache due to dural puncture. Although there are a few case reports about adverse effects of cervical epidural injection in the literature, it can cause severe complications such as large hematoma, infarction by spinal vascular injury. Subdural hematoma has been occurred much less common rather than epidural hematoma in the spinal cord. We report a rare catastrophic case of cervical spinal subdural hematoma with quadriparesis after cervical transforaminal epidural block.
