The authors present the one case of a 22-year-old man admitted with intermittent quadriparesis and respiratory difficulty. On investigation, atlantoaxial instability and upper cervical cord compression due to abnormal soft tissue were revealed. We have performed transoral decompression and biopsy, and then posterior transarticular facet screw fixation with interspinous wiring and fusion. We could obtain immediate and long-term postoperative stability with Philadelphia collar only. The pathologic examination reveald connective soft tissue hypertrophy due to chronic mechanical irritation.

BACKGROUND: Total anomalous pulmonary venous connection (TAPVC) is still one of the more challenging congenital heart defects in newborns and young infants. The purpose of the study is to evaluate the early and midterm results of the surgical corrections for patients in early infancy with isolated TAPVC. MATERIAL AND METHOD: Hospital records of 15 consecutive patients in early infancy (January 1993 to August 1998) were retrospectively reviewed. There were 8 boys and 7 girls whose ages ranged from 4 days to 3.5 months (median age 22 days). Their body weight ranged from 1.75 kg to 4.9 kg (mean 3.54 kg). The abnormal anatomical connections were supracardiac in 11, cardiac in 3, and infracardiac in 1. In 6 patients (40%), the pulmonary venous drainage was obstructive. Total circulatory arrest was used in 13 patients. Anastomosis between the common pulmonary vein and the left atrium was performed with a continuous suture technique using a fine nonabsorbable polypropylene suture through a lateral approach behind the right atrium. RESULT: There was one hospital death (6.5%) caused by a sepsis 17 days after the operation in a neonate who had supracardiac drainage and was dependent on a ventilator preoperatively. There were 2 late deaths. One died sudde`nly of an unknown cause at home 2.5 years after the operation and the other died of a recurrent pulmonary hypertension 3 months after the reoperation due to pulmonary venous obstruction (PVO). Two patients required reoperations because of PVO 5 months and 10 months respectively after the initial operation. Of these patients, one patient is alive at the present time with persistent pulmonary hypertension. All survivors without postoperative PVO (78.6%) were in NYHA functional class I at mean follow-up of 25.8 months (0.5~67 months). CONCLUSION: Surgical correction of TAPVC in early infancy can be performed at low risk. However, there were 2 postoperative PVOs (14.3%) which had bad results. The survivors without postoperative PVO had excellent functional status.

BACKGROUNR/AIMS: Heterogeneity of liver cell populations within the hepatic lobules can affect xenobiotic reaction. In this study, we attempt to clarify the stereological distribution of the y-GTP positive foci in hepatic lobule initiated by diethylnitrosamine and promoted by phenobarbital. METHODS/METERIALS: To the five Sprague-Dawley rats, one day after birth, diethylnitrosamine (0.15 pmole/pn) was intraperitoneally injected and by the weaning at four weeks of life, 0.035% phenobarbital in drinking water was fed for four weeks, at which time the rats were sacrified to obtain the livers. Livers were fixed in fresh cold ethanol acetic acid. Ihe 200 cotmecutive tissue sections were stained by histochemistry for y-GIP and countastained with toluidine blue ar HkE. Employing Zeiss microprojector, y-GTP foci wae traced. And then the largest cross-sectian (size class: 65-165 pm in diameter) of 52 y-GTP foci were selected. Using microscopic grid, distances fiom center of y-GlP foci to nearest centtal vein and bile ductule was measured. As a control group, out of 52 random points determined by rareken digit table, the distances were measured by the same romr. RESULT: the diameter Aom the central points of y-GIP positive foci to the neatest bile ductules was measured as 0.234620+0.14899mm (mean+SD) and the diameter from random points to the neatest bile ductules was measured as 0.303080+0.19582mm (mean+SD). Y-GTP positive foci located within 0.3mm diameter fram bile ductules were counted as 73.1% of 52 foci, whereas that of random points were only 55.8%. Accoring to Aequency table analysis by Shapiro-Wilk W test, there was significant difference by W-value (0.812065) and p-value (0.0144866). CONCLUSION: Stereologically, y -GTP positive foci initiated by diethylnitros;unine, promoted by phaxkarbital in neonatal Spague-Dawley rats were non-rarxlanly distributed in peripcetal atea (Rappaport zone I) in hepatic lobule during hepatocarcinogenesis.

Internal carotid-posterior communicating artery aneurysms are frequently related to third nerve palsy which is reversible after the clipping of aneurysm. The authors had analyzed 61 cases in 52 patients who have posterior communicating artery aneurysm and evaluated the factors affecting the development of third nerve palsy and its recovery after clipping of the aneurysm. The results are followings 1) Oculomotor nerve palsy was noticed in 10 patients(16.4%) among 61 cases of posterior communicating artery aneurysm, of which 6 had complete and 4 had partial palsies. 2) Posteriolateral inferior direction of the aneurysm seemed to be closely related to the development of ophthalmoplegia. 3) Development of ophthalmoplegia was not related to the clinical status of the patient on admission, but to the amount of subarachnoid hemorrhage on initial CT scan and size of the aneurysm. 4) Preoperative degree of third nerve palsy and the timing of operation are not definitely related to the recovery of ophthalmoplegia. 5) The recovery of third nerve palsy are normalization of ptosis, normalization of EOM limitation and normalization of papillary change in order.

It is known that the prognosis of spontaneous SAH(subarachnoid hemorrhage) of undetermined cause is generally favorable. Yet, the natural history and pathogenesis of SAH of undetermined cause remain controversial and patients management is largely empirical. 42 cases of non-traumatic SAH of undetermined cause of a total of 415 cases of SAH treated during a 5-year period(1991-1996) were available for this study. What should be done when angiography is negative after SAH? This study was undertaken to present a more definitive management in preventing rebleeding after SAH of undetermined cause. This study show that explorative craniotomy for aneurysmal operation is warranted, despite negative cerebral panangiograms, if the patient manifests the classical signs and symptoms of SAH and definite subarachnoid blood in CT(computed tomogram) or direct lumbar puncture and any suspicious lesions in cerebral panangiography, particularly the AcoA(anterior communicating artery) region.

PURPOSE: The laparoscopic approach is thought to reduce postoperative immunologic and metabolic effects after surgery compared to the open approach. This study was designed to compare the systemic immune and metabolic responses after laparoscopic and open surgery in patients with colorectal cancer. METHODS: Forty-four patients with colorectal cancer were prospectively assigned to undergo either a laparoscopic (n=22) or open (n=22) approach. The postoperative immune and metabolic responses were assessed by measuring the serum level of the relative proportion of lymphocytes, the T-cell count, the natural killer cell (NK-cell) count, the human leukocyte antigen-DR (HLA-DR) expression on monocytes, the interleukin-6 (IL-6), and the C-reactive protein (CRP) at specific time intervals. RESULTS: Both approaches resulted in a significant decrease in lymphocyte count, T-cell count, NK-cell count, and HLA-DR expression on monocytes at 2, 24, and 72 hours postoperatively. However, the decrease in HLA-DR expression on monocytes was more significant in open surgery at 2 hour postoperatively (mean level, laparoscopic: 90.9% vs. open: 83.1%, P<0.001). Significant rises in IL-6 and CRP were demonstrated within 72 hour postoperatively in both groups. However, no significant difference between the two groups was seen. CONCLUSIONS: Although both laparoscopic and open surgery in patients with colorectal cancer evoked an alteration of the systemic inflammatory and immune response, our data showed that a HLA-DR expression on monocytes may be less compromised after laparoscopic approach for an immediate postoperative period. However, clearer evidence from large-scaled prospective randomized trials are needed.

OBJECTIVE: To evaluate placental causes of fetal death intrauterine (IUFD) bases on placental pathologic findings. METHODS: Retrospective review of 123 placental pathological reports of singleton fetal deaths from 20 weeks of gestation to 41 weeks of gestation. RESULTS: The incidences of maternal causes, fetal causes, inflammatory causes, miscellaneous and unremarkable findings were 45.5%, 28.4%, 16.2%, 23.5%, respectively. The incidence of fetal anomaly was 8.9%. Fetal anomalies were deeply related to fetal cause (P=0.000). Intrauterine growth restriction was significantly associated with maternal causes (P=0.038). CONCLUSION: No pathological guideline regarding placental examination of intrauterine fetal death exists. In future studies, a better definition of fetal death causes and associated placental pathological findings might aid clinicians in counseling, assessing the risk of recurrence and even preventing fetal death in subsequent pregnancies.
