The incidence and risk factors for hypercalciuria were studied in 23 sick preterm (Group I), 36 well preterm (Group II), 16 sick term(Group III)and 41 well term(Group IV) neonates who were admitted to NICU and nursery of Ewha Woman's University Hospital from May 1988 to February 1992. The results were as follws: 1) The incidences of hypercalciuria were 73.9% in sick preterm (Group I) and 56.3% in sick term (Group III) which were significantly higher than 13.9% of control preterm (Group II) and 7.3% of control term (Group IV). Maximal urinary Ca/Cr ration were 0.63+/-0.503 in group I and 0.50+/-0.513 in group III, significantly higher than 0.19+/-0.142 of control term and 0.17+/-0.131 of control term. 2) In sick neonates with hypercalcuria, birth wight and gestational age were significantly lower and the frequencies of frosemide and intravenous calcium therpy were significantly higher than those of sick neonates without hypercalciuria. 3) In sick neonates, furosemide increased the incidence of hypercalciuria to 90.9%, significantly higher than 57.1% in neonates without furosemide. Maximal urine Ca/Cr ratio 24 hour urine calcium were also significantly higher in neonates with furosemide than those of neonates without furosemide. 4) In sick neonates, intravenous calcium gluconate increased the incidence of hypercalciuria to 86.6%, significantly higher than 54.2% in neonates without intravenous calcium. Maximal urine Ca/Cr ratio and 24 hour urine calcium were also significantly higher in neonates treated with IV calcium than those of neonates without IV calcium. 5) Calcium intake and maximal random urine Ca/Cr ratio were positively correlated (r=0.46, p=o.037). In conclusion, the majority of sick newborns in our intensive care unit were hypercalciuric. Sick condition, premature, furosemide and intravenous calcium gluconate were the risk factors that could lead to hypercalciuria. Use of these agents in sick neonates especially preterm neonates requires careful monitoring of urine calcium excretion.

Pecutaneous transhepatic portogram with selective catheterizatio of the portal vein and its tributaries notonly provide information about the status of portal circulation and but can also be used in the treatment ofbleeding esophageal varices by selective embolization with various embolic materials. The authors describe easierand safer modified method of conventional percutaneous transhepatic portogram. We wish to describe our experiencewith the technical aspects and portosystemic collateral patterns in 26 patients with variceal bleeding, from July1985 to July 1986 at Kyungpook National University Hospital. 1. To overcome the difficulties of catheter passageand superselection of variceal supplying vein, we used 7F sheath directly introduced over the ,018″ guide wire.We used coaxial system using 25cm 18G needle within 7F vessel dilator to make the tip of dilator more rigid. 2.Variceal obliteration attempted in 23 patients who showed variceal supplying veins on the protogram, Successfulobilteration was obtained in 20 patients. We used absolute ethanol, stainless steel coil, and Gelfoam cubes withsclerosing and embolica agent of variceal vein. 3. Portosystemic collaterals of 24 patients; Coronary vein;21cases, Inferior mesenteric vein:9 cases, Short gastric vein:7 cases, Umbilical & paraumbilical vein; 6 cases,Gastrorenal: 3 cases, Splenorenal: 2 cases, Splenoretoperitoneal: 1 case. 4. The number of coronay vein were 18cases of single and 4 cases of two. The locations of coronary vein: Splenic vein: 13 cases, Main portal vein: 7cases, Junctional area: 6 cases. 5. Transhepatic obliteration of the gastroesophageal veins is a relatively simpleand usually successful form of palliative treatment for actively bleeding and stable gastroesophageal varices.

Inflammatory myofibroblastic tumor (IMT) of the biliary tree is extremely rare and is generally a benign condition, though malignant change is possible. Making a differential diagnosis between this lesion and other malignant conditions is very difficult on preoperative imaging studies. Hence, the final diagnosis of IMT may be made during or after operation depending on the pathologic examination. We treated a 63-year-old woman who received right hepatectomy with caudate lobectomy under the suspicion of hilar cholangiocarcinoma. Frozen biopsy during the operation showed carcinoma in situ and there were stromal cells in the bile duct's resection margins. The postoperative hospital course was uneventful except for minor bile leakage. At postoperative month 4, she developed jaundice, ascites and pleural effusion. Computed tomography images showed a mass-like lesion in the porta hepatis with portal vein thrombosis and a right chest wall mass. Excisional biopsy was done and the pathology report was malignant spindle cell tumor suggestive of an aggressive form of IMT. Her condition rapidly deteriorated regardless of the best supportive care and she expired at postoperative month 5. Further investigation is necessary to clarify the reasons for recurrence and infiltration of this disease.

Aggressive angiomyxoma is a rare, locally aggressive tumor and occurs exclusively in the pelvic and perineal regions of women. But this tumor can occur in men, and the ratio of man to woman is about 1:6. We report a case of aggressive angiomyxoma of the scrotum in a 75-year-old man. The resected mass measured 23 21 10 cm and weighed 1,150 g, and was covered with thick but intact scrotal skin. The cut surface of the mass showed pale yellow to grayish white loose and edematous fibrous tissue with focal cystic degeneration. Microscopically, the mass was composed of loosely arranged bland-looking spindle or stellate cells and variable sized blood vessels with thickened and hyalinized wall. The spindle cells were strong positive for vimentin, focal, weak positive for desmin and smooth muscle actin but negative for S-100 protein. The spindle cells were also positive for estrogen and progesterone receptors.

We retrospectively analyzed 22 patients pelvic CT, in whom the acetabular fracture were suspected in plain film. And compared and analyzed the computed tomogram findings and plain radiographic findings. The results were as follows. CT enables better evaluation of shape, extent, and degree of separation of fragment. CT was helpful in detecting the combined fracture and soft tissue injuries. CT showed intraarticular loose bodies, which were invisible on plain film. In patients with pelvic trauma, no necessary changing position during CT examination. CT was useful demonstrates the remnant of intraarticular osseous fragment and adequacy of reduction after surgery.

The pinching motion is thought to be one of fundamental hand functions, the power of which has been quantified by measuring it isometrically with variously devised pinch-meters. The present authors describe the investigations on the pinching power of 350 healthy persons, 200 male and 150 female Koreans, by the use of Preston Pinch Gauge. Six kinds of pinch were chosen: (1) thumb index finger tip pinch (1-2TP), (2) thumb-middle finger tip pinch (1-3TP), (3) thumb-index finger pulp pinch (1-2PP), (4) thumb-middle finger pulp pinch (1-3PP), (5) thumb-index-middle finger pulp pinch (3PP), (6) key pinch (KP), which were classified again into 19 kinds according to the shape of thumb, index, middle, or other fingers during each pinch. We describe those as principal type, hyperextension-flexion type, hyperextension type and other type into four. It should be justified to calculate the mean normal value of principal type pinching power in Korean. Principal type of pinch involves 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP, as to Hyperextension type of 1-2PP, 1-3PP, 3PP and KP. Other type of pinch involving 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP is different from Principal type simply because of the shape of nonjoining fingers during pinch. Generally, the pinching power of Principal type was clearly highest among the four types except for pulp pinches.

The coronary artery cross sectional area (CSA) is proportional to LV mass. We have measured the cross sectional area of the left and right coronary arteries in patients with ischemic heart disease to see whether it is related to the change in the LV mass. The following results were obtained ; 1) There were no significant difference in mean CSA of coronary arteries and LV mass determined by echocardiography and cineangiography between control and ischemic heart disease. 2) There were significantly increased ratio of left ventricular mass by cineangiogram to CSA of left anterior descending coronary artery in patients with myocardial infarction as compared with control group. 3) A linear relation between LV mass by cineangiogram and CSA of left coronary artery was noted in control group (r=0.53, P<0.05) and ischemic heart disease group (r=0.51, P<0.05). 4) A linear relation between LV mass determined by echocardiography and CSA of left coronary artery was noted in control group (r=0.55, P<0.05).
