Acute cerebral infarctions are rare in children, however, they can occur as a complication of a Mycoplasma pneumoniae (MP) infection due to direct invasion, vasculitis, or a hypercoagulable state. We report on the case of a 5-year-old boy who had an extensive stroke in multiple cerebrovascular territories 10 days after the diagnosis of MP infection. Based on the suspicion that the cerebral infarction was associated with a macrolide-resistant MP infection, the patient was treated with levofloxacin, methyl-prednisolone, intravenous immunoglobulin, and enoxaparin. Despite this medical management, cerebral vascular narrowing progressed and a decompressive craniectomy became necessary for the patient's survival. According to laboratory tests, brain magnetic resonance imaging, and clinical manifestations, the cerebral infarction in this case appeared to be due to the combined effects of hypercoagulability and cytokineinduced vascular inflammation.

BACKGROUND: Thoracoscopic sympathicotomy was, at first, thought to be a simple and safe method for treatment of hyperhydrosis. However, the main disadvantage of this procedure is irreversibility in additions so-called rebound sweating occurred in 30 40% of patients during the first 1 2 weeks after operation. Some patients regret the surgery, even to the extend of preferring the original sweaty hands. Recently clipping has been suggested one of the way to minimize such problem. Hypothesis of this study was that sympathetic nerve block effect by clipping may be weak compared to sympathicotomy. The aim of this study was to evaluate and compare the sympathicotomy by clipping effect on cardiovascular system. METHODS: Sixty-five patients with essential hyperhydrosis in ASA physical status class 1 undergoing thoracoscopic sympathetic block were randomly divided into two groups: The Clipping group (N = 21) and the sympathicotomy (N = 44) group. Anesthesia was induced with thiopental sodium (5 mg/kg) and pancuronium (0.05 mg/kg) and maintained with enflurane. The operation was done to the left side first and the to the right by an experienced surgeon. During the procedure, we measured blood pressure using a non invasive technique at the right forearm, heart rate and temperature after anesthetic induction as baseline values, immediately after the left side resection of the T2 sympathetic trunk or clipping, and after completely both sides resection. All the records were coded and analysed single blind by one author. RESULTS: After the T2 sympathicotomy, heart rate decreased from 87 +/- 14 to 76 +/- 17 (P < 0.05) and the mean blood pressure was reduced from 77 +/- 14 to 64 +/- 10 mmHg (P < 0.05). After T2 clipping, heart rate decrease from 88 +/- 18 to 73 +/- 14 (P < 0.05) and mean blood pressure was reduced from 74 +/- 12 to 67 +/- 13 mmHg (P < 0.05). CONCLUSION: The main result of this study was that there was no significant difference in sympathetic block effects on blood pressure and heart rate between clipping and sympathicotomy during the procedure.

Spindle cell hemangioma is an uncommon vascular lesion histologically resembling a cavernous hemangioma and Kaposi's sarcoma with a predilection for the extremities. There are no radiologic reports concerning cardiac spindle cell hemangioma in the current literature. We report here a case of cardiac spindle cell hemangioma.

Cystic adventitial disease of the popliteal artery is rare condition, but it is an important cause of peripheral vascular insufficiency in young men. Conventional angiography or MR imaging has traditionally been considered as the study of choice to diagnose this disease. We experienced a case of cystic adventitial disease of the popliteal artery that was diagnosed by 16-slice MDCT angiography, and this imaging modality displayed an accurate diagnostic capability for this disease.

Transforming growth factor-j31 (TGF-p1) has potential for therapeutic use in common clinical conditions for which there are no adequate pharmacological agents. However, in vivo studies using TGF-p1 were hindered by high price of this cytokine. As a first step towards large scale purification of TGF-p1, it was purified in a small scale (10 unit platelets) from human platelets by four purification steps: platelet extraction, gel filtration, cation exchange chromatography, and reversed phase high performance liquid chromatography (HPLC). A single protein band with a molecular weight of 25 Kd corresponding to purchased TGF-p1 (R8D Systems) was confirmed by silver staining after SDS-polyacrylamide gel electrophoresis (SDS-PAGE) of eluant from reversed phase HPLC. Recovery (%) of each step was about 50-60%, resulting in the final recovery of 20% based on the detection by a sandwich ELISA. Approximately, 3.7 p,g of purified TGF-p1 was obtained from 18 pg of platelet extracts. This result was confirmed by receptor (TGF-j31 type II) ELISA and bioassay using a mink lung epithelial'cell line (MV1LU). Further, in vitro characterization study showed that purified TGF-p1 inhibits G1/S transition of LPS-activated murine spleen B cells and increases surface IgA expression by the same cell population, which are typical activities of TGF-p1 in B cell differentiation. Taken together, the results from the present study reveals that purified TGF-p1 is fully biologically active and our purification methodology could be usbful to obtain a large scale of recombinant TGF-p1 in the future.

A stent fracture combined with a coronary artery aneurysm is a rare event. As these events can lead to a harmful outcome, such as the development of myocardial ischemia by in-stent restenosis or thrombosis, repeated coronary intervention may be required. We report a case of a stent fracture combined with a coronary artery aneurysm. The fracture was thought to have developed by mechanical stress produced from a change of regional wall motion after an anteroseptal myocardial infarction. As detected by the use of intravascular ultrasound, neither in-stent restenosis nor a thrombus in the fractured stent was present. A cardiac magnetic resonance image showed that no viable myocardium in the anteroseptal wall was present. Therefore, the patient underwent medical treatment without intervention of the fractured stent.

PURPOSE: The incidence rate of prostate cancer has increased remarkably in Korea. The serum prostate specific antigen (PSA) value has been used for screening, although its clinical significance in prostate cancer screening is still inconclusive. However, if the measurement time was short and the cost was low, such an assay kit should be sufficient for prostate cancer screening. MATERIALS AND METHODS: We developed pared monoclonal antibodies against PSA which could be used in assay kits for PSA. The Rapid PSA Kit(R) used an immunochromatographic method to qualitatively judge a positive or negative result. Serum specimens from 78 men with benign prostate hyperplasia or prostate cancer were tested using the kit. RESULTS: The sensitivity of the kit was determined to be 4ng/ml. 33 samples had a value of greater than 5ng/ml, so were considered positive. 5 samples had values between 4ng/ml and 5ng/ml, of which 3 were positive. The other 40 samples had values less than 4ng/ml, and 11 of these were judged positive. These results indicated that the sensitivity and specificity of the Rapid PSA Kit(R) were 94.7 and 72.5%, respectively. CONCLUSIONS: Tests using the Rapid PSA Kit(R) can be easily performed at outpatient clinics or elsewhere. This kit is useful in the initial screening of prostate cancer as the results can be obtained within 15 minutes and the cost is lower than with ordinary serum PSA tests.
