We measured serum levels of CA-125 and Tissue polypeptide antigen(TPA) in 135 patients with pelvic tumors(129 benign pelvic tumors and 6 malignant ovarian tumors) preoperatively. Each tumor marker was measured by immunoradiometric assay. Serum CA-125 levels of 35.0U/ml, 65.0U/ml and TPA levels of 80.0U/ml, 100.0U/ml were determined as cut-off values. The results were evaluated by each tumor marker and two tumor markers coincidently. The results were as follows : (continue)

An anomalous systemic arterial supply to the normal basal segments of the left lower lobe without sequestration is a rare congenital anomaly. It differs from classical bronchopulmonary sequestration in that the involver lung retains a normal connection to the bronchial tree, although some place this entity exists within the broad framework of pulmonary sequestration. We experienced a case of a woman who presented with a nodular lesion on a chest X-ray. Contrast-enhanced CT diagnosed her as having an anomalous systemic arterial supply to the normal basal segments of the left lower lobe. This case is reported with a brief literature review.

PURPOSE: Appendicitis represents one of the most common surgical disorders. Typically, the diagnosis can be made from well established clinical criteria, with an acceptable negative appendectomy rate from 7~25%. However, when surgical intervention is performed in the patients suspected of having appendicitis but with equivocal clinical findings, the negative appendectomy rate approaches 50%. Routine contrast-enhanced computed tomography (CECT) has described as an accurate diagnostic imaging modality in patients with suspected appendicitis. We evaluated the role of intravenous CECT (iCECT) in patients suspected of having appendicitis but with equivocal clinical exams. METHODS: Eighty seven consecutive patients who were thought to have appendicitis but with equivocal clinical findings and/or physical exams were imaged by iCECT over 18 months period. Intravenous contrast-enhanced, spiral abdominal and pelvic images were obtained using 7.5 mm cuts. iCECT images were interpreted by a board-certified radiologist. Main outcome measures included iCECT sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accurary and negative appendectomy rate in the diagnosis of acute appendicitis, and determining the impact iCECT on the clinical management of the patient population. RESULTS: A group of 87 patients consisting of 36 males (41.4 %) and 51 females (58.6%) with median age of 32 years (range 12 to 75 years) were imaged with iCECT to evaluate suspected appendicitis. Of the 87 iCECTs performed, 8 false-positive and 2 false-negative readings were identified, resulting in a sensitivity of 93.5%, specificity of 85.7%, PPV of 78.4%, NPV of 96%, and an overall accuracy of 88.5%. With regard to clinical management, 100% (31/31) of patients with appendicitis, and 4% (2/50) of patients without appendicitis underwent appendectomy. Therefore, the overall negative appendectomy rate was 6.1% (2/33). CONCLUSION: iCECT is a useful diagnostic imaging modality for patients suspected of having acute appendicitis but with equivocal clinical findings and/or physical exams. iCECT is particularly useful in excluding the diagnosis of appendicitis in those without disease.

BACKGROUND: Pulmonary Langerhans cell histiocytosis forms part of a spectrum of diseases that are characterized by a monoclonal proliferation and infiltration of organs by Langerhans cells. Several organ systems may be involved in Langerhans cell histiocytosis, including the lungs, bone, skin, pituitary gland, liver, lymph nodes and thyroid. Pulmonary histiocytosis X represents 2.8% of interstitial lung disease. Here we present the clinical, radiological, therapeutic aspects of pulmonary histiocytosis X. METHOD: Fourteen cases of biopsy-proven pulmonary histiocytosis X patients who were diagnosed in Seoul National University Hospital during the period from January 1990 to December 1998 were analyzed retrospectively. RESULT: There were 12 men and 2 women in this study. The initial presenting symptoms were dyspnea, cough, chest pain, which was associated with the pneumothorax, and chest radiography abnormalities. Only 8 patients (57%) were smokers. There were 5 patients with extra-pulmonary histiocytosis (pituitary, bone, skin). Eight patients had received the chemotherapy. There were no mortalities and only one patient experienced an aggravation of symptom during the follow-up period. CONCLUSION: In contrast to previous reports from other countries, the patients with pulmonary histiocytosis X in this study presented with several different clinical characteristics, such as a male predominance, relatively low smoker's rate, and a better prognosis.

BACKGROUND: Post-operative shivering is one of the potential complications for any surgical patient. Its incidence varies from 5% to 65%, and many preventive and treatment modalities have been reported. For the effective prevention of post-anesthetic shivering by using intravenous clonidine or meperidine, randomized controlled studies were reviewed. The overall incidence of shivering after clonidine or meperidine administration, and the anti-shivering effect of clonidine and meperidine were evaluated. METHODS: DATA SOURCES: Medline search from 1978 to March 1998. DATA SELECTION: We selected studies that had investigated the preventive anti-shivering effect of intravenous clonidine or meperidine by randomized controlled trials. Ten clinical trials were evaluated. RESULTS: The pooled odd ratio of the patients who received clonidine was 0.32 (95% confidence interval, 0.22~0.47) and it seemed to be effective. But these studies showed little evidence of significant homogeneity (P=0.01). In the subgroup analysis, the pooled odd ratio of group A (early administration or intra-operative infusion group) was 0.47 (95% CI 0.31~0.72) evidenced effectiveness but failed to prove homogeneity (P=0.047). But group B (the late intra-operative administration group) had a pooled odd ratio of 0.10 (95% CI 0.05~0.22) and showed homogeneity (P=0.98). In meperidine trials, the pooled odd ratio was 0.20 (95% CI 0.07~0.55). CONCLUSION: We present quantitative evidence based on a meta-analysis of pooled effect size from randomized trials that clonidine is more beneficial for the prevention of post-anesthetic shivering and more effective than meperidine when it is administrated during later period of surgery.

Ectopic pregnancy and appendicitis in pregnancy are two most common causes of acute abdomen in young women and differenciation of these diseases is very difficult. Heterotopic pregnancy is a rare event, occuring less than 1:30,000 pregnancies in natural conception cycles. However, with assisted reproduction techniques, this incidence has increased. We experienced a case of spontaneous heterotopic pregnancy after missed abortion and acute appendicitis treated by laparoscopy. So we report this case with brief review of literature.

Cesarean scar pregnancy is one of the rarest forms of ectopic pregnancy. Little is known about its incidence and natural history. With increasing incidence of caesarean section worldwide, more and more cases are diagnosed and reported. Transvaginal ultrasound and colour flow Doppler provides a high diagnostic accuracy with very few false positives. A delay in diagnosis and/or treatment can lead to uterine rupture, major haemorrhage, hysterectomy and serious maternal morbidity. Surgical management can be safe and effective and medical treatment can be selected as appropriate selection criteria. Patients with history of a pregnancy in a cesarean delivery scar should be advised of the risk for future uterine rupture and placenta accreta. We experienced a case of ectopic pregnancy with treatment of surgical excision and report with a brief review of literatures.

BACKGROUND: Some chemotherapeutic drugs induce NF-κB activation by degrading the IκBα protein in cancer cells which contributes to anticancer drug resistance. We hypothesized that inhibiting IκBα degradation would block NF-κB activation and result in increased tumor cell mortality in response to chemotherapy. METHODS: The "superrepressor" form of the NF-κB inhibitor was transferred by an adenoviral vector (Ad-IκBα-SR) to the human lung cancer cell lines (NCI H157 and NCI H460). With a MTT assay, the level of sensitization to cisplatin and paclitaxel were measured. To confirm the mechanism, an EMSA and Annexin V assay were performed. RESULTS: EMSA showed that IκBα-SR effectively blocked the NF-κB activation induced by cisplatin. Transduction with Ad-IκBα-SR resulted in an increased sensitivity of the lung cancer cell lines to cisplatin and paclitaxel by a factor of 2~3 in terms of IC50. Annexin-V analysis suggests that this increment in chemosensitivity to cisplatin probably occurs through the induction of apoptosis. CONCLUSION: The blockade of chemotherapeutics induced NF-κB activation by inducing Ad-IκBα-SR, increased apoptosis and increasing the chemosensitivity of the lung cancer cell lines tested, subsequently. Gene transfer of IκBα-SR appears to be a new therapeutic strategy of chemosensitization in lung cancer.

PURPOSE:The objective of this study was to evaluate the indications, effectiveness and complications associated with uterine arterial embolization as an alternative treatment of obstetrical hemorrhage. METHODS:From January 2006 to December 2008, 25 patients who underwent angiographic embolization for the obstetrical hemorrhage that was not responsive to conventional treatments, like obstetric maneuvers and uterotonic drugs, were included in our study. All medical records were reviewed and detailed clinical data such as clinical status, underlying conditions, amount of transfusion, embolized arteries, hospital stay, the success rate and the complications were collected. RESULTS:We have experienced clinically successful embolization in 22 (88%) of 25 patients with obstetrical hemorrhage resulting from various causes. After embolization, the patients' vital signs were stabilized. The causes of hemorrhage were atony of uterus (n=10), myomectomy during cesarean section (n=6), abnormal placentation (n=5), arterio-venous malformation (n=3), and cervical pregnancy (n=1). The average amount of blood transfusion was 7.2 units (range; 0~39 units). The average length of the time for the procedure was 55 minutes (range: 25~96 minutes). The average duration of hospitalization was 5.5 days (range: 2~14 days). In 22 patients, menses resumed spontaneously after procedures. The main complications after embolization were numbness and pain on lower extremities (n=1), and hypomenorrhea (n=1). CONCLUSION:The atrerial embolization is one of the safe and effective procedures that offers patients an alternative to hysterectomy for the treatment of intractable postpartum hemorrhage.

The unique clinical syndrome of the uterus didelphys, a unilateral partially or completely obstructed vagina, and ipsilateral renal agenesis is quite rare, and observed on the right side in greater frequency than on the left. The case of fifteen year old girl with uterus didelphys, unilateral partially obstructed vagina and acute renal failure associated with ureteral stone in unilateral kidney is described. Extracorporealshock wave lithotripsy (ESWL) and evacuation of the hematocolpos and excision of the vaginal septum were done. Aware of this relatively rare condition is mainstay of prompt diagnosis which will prevent permanent renal failure and unnecessary and destructive surgery.
