BACKGROUND: Epidural analgesia, via either a thoracic or lumbar route, is commonly used to provide postoperative analgesia following thoracotomy for pulmonary resection, but little data indicate which location is better in terms of postoperative analgesia, side effects, or associated complications. METHODS: 54 patients, who undergo a lateral thoracotomy, were randomized to receive a mixture of fentanyl and 0.15% bupivacaine at 0.5microgram/kg/hr of fentanyl via either a thoracic (Group T) or a lumbar (Group L) catheter. Postoperative pain was assessed 6hrs after the operation and everyday for 5 days on a visual analog scale (VAS). Postoperative side effects and patients satisfaction of epidural analgesia were assessed by 4 grades system. RESULTS: The VAS scores during coughing were higher than those of resting state without intergroup differences. The incidences and severity of side effects (nausea, vomiting, pruritus, sedation) were not different between group T and group L, but the incidence of urinary retention attributable to use of the lumbar epidural route was significantly higher than with the thoracic route (p<0.05). CONCLUSIONS: The authors conclude that there is no clinical advantage of thoracic over lumbar epidural fentanyl in the thoracotomy patients with respect to analgesia and incidences of most side effects except urinary retention.

Implantation of a pregnancy within the scar of previous cesarean section is the rarest form of ectopic pregnancy. If diagnosed early, treatment options are capable of preserving the uterus and subsequent fertility. However, delayed diagnosis and treatment can lead to uterine rupture, hemorrhage and maternal morbidity. We present two cases of ectopic pregnancy developing in the previous cesarean section scar in which successfully treated with dilatation and evacuation after vaginal misoprostol.

PURPOSE: The cause of aseptic meningitis remains mostly unknown because viral culture and identification is difficult. Thus, we report a study on 123 children with aseptic meningitis in Gyeongju in 2002 to identify the causing virus and the relationship with the clinical manifestation. METHODS: We prospectively investigated the patients, admitted to Dongguk University Hospital, into two groups between April and October 2002. Group 1 included 123 patients diagnosed as aseptic meningitis. Group 2, the adimssion control, included 120 patients, who suffered from none-enteroviral diseases. Specimens of CSF and stool were collected to perform reverse transcription polymerase chain reaction(RT-PCR), and enteroviral culuture was done in RT-PCR positive patients as well. RESULTS: The male to female sex ratio was 2.2:1 and the mean age was 6.2+/-3.7 years. The clinical manifestations were fever, headache and vomiting. The RT-PCR for enterovirus, performed in 58 cases of CSF in group 1, showed 5.2% positive results and negative result in viral culture. The RT-PCR for enterovirus used in stool specimens showed 89.3% and 41.1% of positive results in group 1 and group 2, respectively. Viral culture of stool specimens showed five cases of echovirus 13 and four cases of echovirus 6 in group 1, whereas three cases of echovirus 6 and one case of coxsackie B4 were detected in group 2. CONCLUSION: The etiologic viruses of the aseptic meningitis outbreak in Gyeongju in 2002 is presumed to be echovirus 13 and echovirus 6. Since echovirus 13 firstly appeared with various age distributions, the outbreak may have emerged due to a lack of acquisition of immunity to this virus.

Most hamartomatous polyps in the stomach occur in patients with adenomatous polyposis coli and dysplasia. The authors report a case of a 57-year-old man without prior history of polyposis coli who presented with adenocarcinomas derived from hamartomatous polyps in the stomach. The patient underwent a radical subtotal gastrectomy with Billroth I anastomosis. Pathology revealed adenocarcinomas with moderate differentiation without evidence of lymph node metastasis in 60 nodes. We report a case of gastric cancers arising from de novo gastric hamartomatous polyps.

Heterotopic pregnancy, simultaneous intrauterine and extrauterine pregnancy, classically was considered a exceedingly rare obstetrical phenomenon. But nowadays the natural incidence is increasing and especially in association with assisted reproductive technologies, such as use of variable methods for ovulation inductions, in-vitro fertilization and embryo transfer, and gamate intrafallopian transfer. In spite of the difficult early diagnosis, which is potentially dangerous to the mother and fetus, the maternal mortality, morbidity and fetal loss is low when the diagnosis is made in timely fashion and proper management is achieved. The presence of a intrauterine pregnancy dose not exclude the possibility of a extrauterine pregnancy, and in women associated with assisted reproductive technologies, the possibility of a heterotopic pregnancy should be considered. We report a case of a heterotopic pregnancy following ovulation induction and intrauterine insemination with brief review of literature.

BACKGROUND: Chronic placental inflammation, such as villitis of unknown etiology (VUE) and chronic chorioamnionitis (CCA), is considered a placental manifestation of maternal anti-fetal rejection. The aim of this study is to investigate its frequency in twin pregnancies compared to singleton pregnancies. METHODS: Three hundred twin placentas and 1,270 singleton placentas were consecutively collected at a tertiary medical center in Seoul, Republic of Korea from 2009 to 2012. Hematoxylin and eosin sections of tissue samples (full-thickness placental disc and chorioamniotic membranes) were reviewed. RESULTS: Non-basal VUE was more frequent in twin placentas than in singleton placentas (6.0% vs 3.2%, p < .05). In preterm birth, CCA was found less frequently in twin placentas than in singleton placentas (9.6% vs 14.8%, p < .05), reaching its peak at an earlier gestational age in twin placentas (29-32 weeks) than in singleton placentas (33-36 weeks). CCA was more frequent in twin pregnancies with babies of a different sex than with those with the same sex (13.8% vs 6.9%, p=.052). Separate dichorionic diamniotic twin placentas were affected by chronic deciduitis more frequently than singleton placentas (16.9% vs 9.7%, p<.05). CONCLUSIONS: The higher frequency of non-basal VUE in twin placentas and of CCA in twin placentas with different fetal sex supports the hypothesis that the underlying pathophysiological mechanism is maternal anti-fetal rejection related to increased fetal antigens in twin pregnancies. The peak of CCA at an earlier gestational age in twin placentas than in singleton placentas suggests that CCA is influenced by placental maturation.

OBJECTIVE: Retrospective analysis to compare the effect and complication of epidural patient-controlled analgesia (epidural PCA) with intravenous patient-controlled analgesia (IV PCA) for the treatment of the post-operative pain after posterior lumbar instrumented fusion. METHODS: Sixty patients who underwent posterior lumbar instrumented fusion for degenerative lumbar disease at our institution from September 2007 to January 2008 were enrolled in this study. Out of sixty patients, thirty patients received IV PCA group and thirty patients received epidural PCA group. The pain scale was measured by the visual analogue scale (VAS) score. RESULTS: There were no significant difference between IV PCA group and epidural PCA group on the PCA related complications (p=0.7168). Ten patients in IV PCA group and six patients in epidural PCA group showed PCA related complications. Also, there were no significant differences in reduction of VAS score between two groups on postoperative 2 hours (p=0.9618) and 6 hours (p=0.0744). However, postoperative 12 hours, 24 hours and 48 hours showed the significant differences as mean of reduction of VAS score (p=0.0069, 0.0165, 0.0058 respectively). CONCLUSION: The epidural PCA is more effective method to control the post-operative pain than IV PCA after 12 hours of spinal fusion operation. However, during the first twelve hours after operation, there were no differences between IV PCA and epidural PCA.

Background: We evaluated the efficacy of Dor procedure in patients with ischemic left ventricular dysfunction. Material and Method: Between April 1998 and December 2002, 45 patients underwent the Dor procedure concomitant with coronary artery bypass grafting (CABG). Left ventricular ejection fraction (LVEF) and left ventricular end-diastolic/end-systolic volumes (LVEDV/LVESV) were measured by echocardiography, myocardial SPECT, and cardiac catheterization and angiography performed at the sequence of preoperative, early postoperative, and one year postoperative stage. Result: Cardiopulmonary bypass and aortic clamp times were mean 141+/-64, 69+/-24 minutes, respectively. Intraaortic balloon pump (IABP) therapy was required in 19 patients (42%; 7 preoperatively, 9 intraoperatively, 3 postoperatively). Operative mortality rate was 2.2% (1/45). Postoperative morbidities were low cardiac output syndrome (12), atrial fibrillation (5), acute renal failure (4), and postoperative bleeding (4). Functional class (NYHA) was improved from classes 2.8 to 1.1 (p<0.01). When we compared between the preoperative and early postoperative values, LVEF was improved from 32+/-9% to 52+/-11% (p<0.01). The asynergy portion decreased from 57+/-12% to 22+/-9%, and LVEDV/LVESV indexes improved from 125+/-39 mL/m2, 85+/-30mL/m2 to 66+/-23 mL/m2, 32+/-16 mL/m2 (p<0.01). Although these changes in volumes were relatively preserved at postoperative one year, the left ventricular volumes showed a tendency to increase. Conclusion: After the Dor procedure for ischemic left ventricular dysfunction, LVEF improvement and left ventricular volume reduction were maintained till postoperative one year. The tendency for left ventricular volume to increase at postoperative one year suggested the requirement of strict medical management.

BACKGROUND: Two dimensional echocardiographic monitoring of left ventricular resional wall motion abnormalities(RWMA) with incremental injection of ergonovine up to 350microg(ErgEcho) is useful for a noninvasive diagnosis of coronary vasospasm(CVS). The prevalence that CVS may evoke unstable angina(UA). However, this theory has not been the subject of any systematic analysis to date. This prospective study was carried out on patients who had been tentatively diagnosed as having UA when they were carried out on patients who has been tentatively diagnosed as having UA when they were admitted to the coronary care unit due to chest pain. The aim was to determine the significance of CVS in the clinical spectrum of UA and the value of Erg Echo when applied to this situation. METHODS: With antianginal medications a diagnostic coronary angiography was done to rule out significant fixed athrosclerotic disease(FD), with more than 70% narrowing of luminal diameter. In patients with normal coronary angiograms of insignificant FD. Erg Echo was performed to diagnose CVS after the discontinuation of all antianginal medications. All patients with postinfarction or secondary angina were excluded in this study. RESULTS: Of 191 patients(135 males, 57+/-9 yrs) enrolled from Mar 1992 to June 1993,71%(135/191) showed significant FD in the angiography. CVS was documented in 18%(34/191) using Erg Echo with mean injected ergonovine dosage of 125+/-89microg. In patients with CVS only 24%(8/34) had mild fixed lesion in the angiography with mean luminal narrowing of 60%(+/-12%). RWMA in the territory of left anterior descending artery was the most common(70%, 24/34). Other causes of chest were esophageal spasm in 3 patient(1%, 3/191) and hypertrophic cardiomyopathy in 2 patients, and 17 patients were diagnosed as having chest pain of unkwnon etiology. One of them redeveloped chest pain 2 months later. when repeated Erg Echo revealed RWMA. Others were symptom free during the follow-up(8+/-4 months) and there were no cardiac events. CONCLUSION: Our data suggest that in patients presenting UA in Korea, CVA is the main cause of myocardial ischemia in considerable number of patient, and Erg Echo after the angiography is useful and safe for noninvasive diagnosis of CVS in this situation.
