Bilateral frontal polymicrogyria is a recently recognized syndrome characterized by symmetric polymicrogyria of both frontal lobes that presents with delayed motor and language development, spastic quadriparesis, and variable mental retardation. However, the postmortem findings of this syndrome are not fully elaborated. Here we describe an autopsy case of bilateral frontal polymicrogyria in a male fetus delivered at 22 weeks gestation due to extensive chorioamnionitis. The microscopic findings included a thinned cortical plate with fair neuronal maturation. There were no signs of neuronal damage and the white matter was unremarkable.

The term "pineal anlage tumor" has been recently proposed and few cases have been reported. We report the first Korean case of pineal anlage tumor in a 6-year-old girl who complained of headache and vomiting for 2 months. Brain MRI revealed a well defined, lobulated, calcifying mass in the pineal region. Tumor was totally removed. Pathological examination revealed a primitive pineal parenchymal tumor with melanotic epithelial component that was similar to histologic findings of melanotic neuroectodermal tumor of infancy, so-called retinal anlage tumor and of the developing pineal gland. The tumor was composed mostly of small, undifferentiated cells, Flexner-Wintersteiner rosettes, and ganglionic differentiation. The tumor also contained the cartilage and skeletal muscle cells.

PURPOSE: This study was performed to evaluate differentiating features of spinal compression fractures between benign and metastatic lesions. MATERIALS AND METHODS: We reviewed MR imaging in 52 patients (benign 38, metastasis 14) with vertebral compression fracture. Signal intensity of fracture and uninvolved areas, presence of contrast enhancement, fragmentation, and paravertebral mass were analyzed retrospectively. RESULTS: Signal intensity of fracture site was variable in benign lesions, but low signal intensity on T1-weighted image and high on T2*-weighted image were seen in all cases of metastasis. Signal intensity of uninvolved area was high on T1-weighted image and low on T2*-weighted image in 84% of benign lesions. On the contrary, normal marrow signal intensity was not seen in the uninvolved areas of all metastatic fractures. Contrast enhancement were observed in all cases of benign & metastatic compression fractures. Fragmentation were seen in 1 case of metastasis(7%) and in 11 cases of benign lesions(29%). Paravertebral mass were seen in 5 cases of metastasis(36%) and in 7 cases of benign lesions(18%). CONCLUSION: Presence of normal marrow signal intensity in the uninvolved area of fracture site could be the most useful sign for differentiating benign causes from metastasis.

Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.

The use of interlocking intramedullary nail is accepted one of treatment choices in the comminuted fractures of humeral shaft. The insertion of distal interlocking screws remains technically problematic. The use of intrageon's hands during the procedure. In order to reduce technical difficulty and radiation exposure, it is necessary to compare the rigidity of intramedullary nail according to the number of distal interlocking screws. The purpose of study is to compare the stability of interlocking intramedullary nail according to the number of distal screws by means of torsional compliance measurements in the simulated humeral shaft fractures. Simulated fractures were made in 20 humora from 10 cadavera at the mid-junction of humeral shaft. All humora were fixated with titaium humeral nail system. Interlocking screws were placed at proximal and distal screw holes by standard procedure. Group I consisted of 10 humora fixated with one distal interlocking screw and group II consisted of 10 humora fixated with two distal intterlocking screws. Torsional compliance was measured with single-end of 10 humora fixated with two distal interlocking screws. Torsional compliance was measured with single-end double arm torquing machine. The torsional compliance analog was 0.0294+/-0.0033 mm/N mm for one screw and 0.0241+/-0.0045 mm/N mm for two distal screws. The torsional compliance analog between two groups was found to be statistically insignificant(p=0.23). In conclusion, One distal interlocking screw was not inferior to two interlocking screws in terms of biomechanical characteristics, especially torsional compliance analog.

BACKGROUND: In two-kidney one clip Goldbaltt hypertensive rats(2K1C GHR), clipped kidney may be exposed to low pressure and unclipped kidney to high pressure. In addition, both kidneys may have a different amount of adenosine which is increased by ischemia and plays an important role for renin release. The aim of this study was to invstigate the responsmiveness for renin release to adenosine agonists and antagonist in clipped and unclipped kidney of 2K1C GHR. METHODS: Emplying kidney slices from both unclipped and unclipped kidney of 2K1C GHR, the alteration by adenosine agonists and antagonist of renin release was studied. RESULTS: The renal renin content and basal renin release from unclipped kidney slices were suppressed, whereas those from clipped kidney were augmented Adenosine Al receptor agonist, cyclohexyladenosne(CHA), phenylisopropyl adenosine(PIA) and adenosine caused a decrease in renin release from clipped kidney slices. Adenosine A2 receptor agonist, NECA, and nonspecific adenosine receptor aganist, 2-chloroadenosine(CA) caused an increase in renin release from clipped kidney slices. Adenosine receptor antagonist, 8-phenyltheophylline(8-PT) caused an increase in renin release from clipped kidney slices. In unclipped kidney, however, the renin release in response to NECA, CA or 8-PT was reversed and the decreasing effect of renin release to CHA and adenosine was slightly inereased. CONCLUSION: These results suggest that the responsiveness of adenosine receptors, which may participate in renin release is modified in clipped and unclipped kidney of 2K1C GHR.
