To evaluate the high-resolution computed tomography (HRCT) findings of pleuropulmonary involvement in systemic lupus erythematosus (SLE), we analyzed HRCT findings of 12 patients of clinically confirmed SLE with respiratory symptoms. In four patients, HRCT findings before and after chemotherapy were compared. The common HRCT findings were ground-glass opacity (100%), bronchial wall thickening (66%), patchy parenchymal opacity (58%), septal or intralobular line thickening (58%), micronodule (58%), central core prominence (41%), small pleural effusion (91%), and pericardial effusion (33%). Follow-up HRCT obtained after treatment showed significant improvement of pleural effusion(4/4), pericardial effusion (3/3), pericardial thickening (1/1), patchy opacity (2/2), and ground glass opacity (2/4). But bronchial wall thickening (2/2) and micronodule (2/2) were not improved. Although there are no pathognomonic HRCT findings in SLE, bilateral small pleural effusion, ground glass opacity, subpleural patchy opacity, and micronodule are common and suggestive findings in the pleuropulmonary involvement of SLE.

Lymphangioma occuring in the gastrointestinal tract is a rare benign tumor, which is composed of lymphatic vessels of various size. A sharply demarcated smooth, soft, cystic submucosal tumor which is easily compressible and covered with normal mucosa is a characteristic eadoscapic feature. Recently, we experienced a case of lymphangioma in ascendmg colon and removed it successfully by colonoscopic snare polypectomy.

Hepatie hilar ductal carcinoma is relatively rare, but the prognosis is known to be poor because an early diagnosis is difficult. Because the majority of patients are already infiltrated into adjacent organ by itself at the diagnosis, the rate of resectability is low. The best method of treatment is curative resection, and the range of tumor invasion is very important. The preoperative diagnosis is difficult because the cholangiography may be normal in cases of superficial invasion. Multifocal lesions within the biliary tract may be identified in as many as 10 percent of patients, Especially, the papillary type has the best prognosis and is associated with multiple tumors within the bile duct. We report a case that percutaneous transhepatic cholangiogram showed normal distal common bile duct, but the hepatic hilar confluence and ampulla of Vater lesion was confirmed as adenocarcinoma.

BACKGROUND: There is a strong evidence that administration of anti-tumor drugs triggers apoptotic death of target cells. Therefore, quantitation of the 0early apoptotic cells could provide a very useful information for clinicians planning anti-tumor strategies. Therefore, we measured the amount of early apoptotic cells using annexin-FITC/PI dual fuorescence method by which early changes of apoptotic cell membrane could be detected. We also measured DNA content of apoptotic cells by PI single stain and performed DNA fragment assay simultaneously. METHODS: HL-60 cell line were cultured under 100, 200 ng/mL adriamycin for 12, 24, 36, 48 hours. Quantitation of the early apoptotic cells was done using flow cytometry with annexin-FITC and Propidium iodide (PI) dual fluorescence stain. And DNA content of the HL-60 cells was measured using PI single stain after fixing the cells. DNA ladder assay was also performed by agarose gel electrophoresis. RESULTS: The early apoptotic cells were 40.5% at adriamycin 100 ng/mL, after 24 hours culture and the secondary necrotic cells were 94.7% at adriamycin 200 ng/mL after 48 hours culture. There was a good correlation between annexin-PI stain and DNA content analysis. We could find DNA fragmentation on agarose gel electrophoresis. CONCLUSION: Quantitation of the early apoptotic cells using flow cytometry with annexin-PI dual fluorochrome stain and the DNA content analysis with PI single stain could be a good parameter for anti-apoptotic strategies.

PURPOSE: To report ocular findings of a mucolipidosis type II patient with novel mutation. CASE SUMMARY: A 10-year-old boy visited our pediatric genetic metabolic clinic for evaluation of his overall developmental delay and short stature. The boy was diagnosed with mucolipidosis type II (I-cell disease) using plasma enzyme assay and DNA sequencing of the GNPTAB gene mutation. An ophthalmologic investigation was then performed, and a depressed nasal bridge, broad nose, and swelling in the upper lid of both eyes were noted. The best corrected visual acuity was 0.32 and 0.1 and the intraocular pressure was 35 mmHg and 24 mmHg in the right and left eyes, respectively. The anterior chamber angles of both eyes were normal and mild cornea opacity in both eyes was observed. Fundus examination revealed retinal atrophy with folds in both eyes, as well as optic disc edema and optic atrophy in the right and left eyes, respectively. Atherosclerotic changes in the retinal vessels and cystoid macular edema in the left eye were observed, and ocular ultrasound revealed increased posterior sclera thickness in both eyes. CONCLUSIONS: Ocular manifestations of mucolipidosis type II are not currently well-known, and differentiation from other metabolic disorders may be difficult. An ophthalmic work-up can assist in diagnosis, and regular ophthalmic examinations should be used to maintain visual function in mucolipidosis patients.

Spinal hemangioma is the uncommon, slowly growing benign tumor that arises from the blood vessels and commonly located in thoracic spine. We have recently experienced a caseof capillary Hemangioma in intradural extramedullary space of thoracic spine level. The patient presented with a slowly progressive weakness of both lower extremities and hypesthesia below T6 dermatome. The plain X-ray films, thoracic spine myelography and CT scan disclosed an intradural mass at T5 level. The mass was surgically removed and conformed by histological examination.
