Although halothane is generally anesthetic of choice for asthmatics due to its bronchodilatory action, its combined use with aminophylline should be discouraged. This report is a 43-year-old male who had primary closure and open reduction internal fixation (ORIF) for facial avulsion injury and zygomatic tripod fracture under N2O-O2-halothane anesthesia. About 90 minutes after the procedure, the patient who had aminophylline infusion for an acute bronchospasm developed a sudden cardiac arrest. The immediate cardiopulmonary resuscitation was applied and the patient was recovered without any neurological deficit. At the time, the serum theophylline concentration of the patient was 16 microgram/ml which was in the range of normal therapeutic dose. The cause for this cardiac arrest by halothane is unknown, but possibly a drug interaction between halothane and aminophylline might have contributed, since halothane sensitizes the heart to exogenous catecholamines.

Agenesis of dorsal pancreas is a rare congenital anomaly that arises from the failure of the dorsal pancreatic bud of endodermal cells to form the body and tail of the pancreas. It may be associated with diabetes mellitus, pancreatic exocrine dysfunction, or abdominal pain. Complete or partial agenesis of dorsal pancreas has been reported in a small number of pediatric and adult patients. A case is herein described involving a complete agenesis of dorsal pancreas and diabetes mellitus. A 38-year-old man with a 7-months history of non-insulin dependent diabetes mellitus was admitted due to weight loss and abdominal pain. Abdominal ultrasonography and computed tomography showed a normal biliary tree and enlarged head of the pancreas without visualization of the pancreatic body and tail. Endoscopic retrograde cholangiopancreatography (ERCP) revealved the short duct of Wirsung in the uncinate process and a head without opacification of any ducts in the pancreatic body or tail. The patient underwent explo-laparotomy for evaluation of the suspected pancreatic cancer. The patient was diagnosed as having complete agenesis of the dorsal pancreas by ERCP, CT, and surgery.

OBJECTIVE: A Clinical Study of Placenta P#revia done by cesarean section and the study of preterm delivery that is major cause of premature motality even thought expected managment of placente previa. METHODS: This study was evaluated for the clinical analysis on the 641 patients with placenta previa among total deliveries of 56,120 cases at the St. Mary and Holy Family hospital of Catholic University from Jan. 1,1989 to Dec.31,1997. RESULTS: The following results were obtained: 1. The total incidence of placenta previa was 1.14%. 2. The incidence of placenta previa increases with age. 3. Placenta previa has occurred more often in multipara(60.2%) than primipara(39.8%), and placenta previa has occurred more often in women who had experienced abortion(71.8%) than women who hadnt(28.2%). 4. The types of placenta previa distributed 326 cases of totalis(50.9%), 110 cases of partialis(17.2%), 99 cases of marginal(15.4%) and 106 cases of low lying placenta(16.4%). 5. The fetal presentation distributed 557 cases of vertex(86.9%), 49 cases of breech(7.6%), 28 cases of transverse lie(4.4%). 6. The types of uterine incision included 543 cases of low sepnent transverse incision(84.7%), 46 cases of classical incision(7.2%), 9 cases of inverted T incision and 43 cases of cesarean hysterectomy(6.7%). 7. Premature delivery of placenta previa prior to completion of 37 weeks was 186 cases(29.0%) and low birth infant less than 2,500gm was 128 cases(20.0%).and perinatal mortality rate was 28.0 per 1,000. 8. During delivery, 278 cases of placenta previa(43.4%) were transfused with mean 3.6 pints. Incidence of vaginal bleeding was 49.3% of placenta previa,mean admission day until delivery was about 5 day. CONCLUSION: there is a strong association between advancing age and incidence of placenta previa, and then. the risk increases with parity & the number of abortion. Considering the mean volume of blood loss more than 3 pints of blood should be prepared befor delivery.

BACKGROUND: Greater occipital nerve block is used in the treatment of headaches and neuralgia in the occipital area. We evaluated the efficacy of ultrasonic doppler flowmeter-guided occipital nerve block in patients experiencing headache in the occipital region in a randomized, prospective, placebo-controlled study. METHODS: Twenty-six patients, aged 18 to 70, with headache in the occipital region, were included in the study. Patients received a greater occipital nerve block performed either under ultrasonic doppler flowmeter guidance using 1% lidocaine or the traditional method. Sensory examination findings in the occipital region were evaluated. RESULTS: The complete block rate of greater occipital nerve blockade in the doppler group was significantly higher than in the control group respectively (76.9% vs. 30.8%, P < 0.05). Only one patient in the control group had a complication (minimal bleeding). CONCLUSIONS: Ultrasonic doppler flowmeter-guided occipital nerve block may be a useful method for patients suffering headache in the occipital region.

BACKGROUND/AIMS: Periostin is an extracellular matrix protein and is known to be related to the metastatic potential and prognosis of cancer. However, few studies have investigated the expression level of periostin and its association with prognoses in hepatocellular carcinoma. Therefore, we analyzed periostin overexpression in hepatocellular carcinoma and its implication for prognoses. METHODS: We evaluated 149 patients who underwent surgical resection between 2006 and 2010. Tissue microarrays were constructed from hepatocellular carcinoma tissue and adjacent nontumor tissue, and immunohistochemistry was performed. RESULTS: A high periostin level was observed more frequently in cases of multiple tumors (odds ratio [OR], 2.826; 95% confidence interval [CI], 1.224 to 6.527; p=0.013), positive microvascular invasion (OR, 2.974; 95% CI, 1.431 to 6.181; p=0.003), and advanced stage disease (OR, 3.032; 95% CI, 1.424 to 6.452; p=0.003). Patients with high periostin expression had significantly (p=0.002) lower overall survival rates than those with low periostin expression (90.3%, 66.1%, and 56.2% vs 97.7%, 85.1%, and 77.5% at 1, 3, and 5 years). CONCLUSIONS: We found that a combination of periostin overexpression and microvascular invasion in hepatocellular carcinoma was correlated with a poor prognosis and can be a good prognostic marker for hepatocellular carcinoma.

Background: Mac-2 binding protein glycosylation isomer (M2BPGi) has been established as a non-invasive biomarker for liver fibrosis. We evaluated the diagnostic efficacy of M2BPGi compared with those of other liver fibrosis markers in liver fibrosis in non-alcoholic fatty liver disease (NAFLD). Methods: We analyzed serum M2BPGi levels in 113 NAFLD patients. A pathologist graded liver fibrosis histopathologically. The diagnostic efficacies of serum M2BPGi and other liver fibrosis markers (aspartate aminotransferase to platelet ratio index, fibrosis index based on four factors, and NAFLD fibrosis score [NFS]) were evaluated using correlation, area under the ROC curve (AUC), logistic regression, and C-statistics. Results: Serum M2BPGi level and other liver fibrosis markers showed a moderate correlation with fibrosis grade. The AUC values of M2BPGi were 0.761, 0.819, 0.866, and 0.900 for diagnosing fibrosis (F) > 0, F > 1, F > 2, and F > 3, respectively. Logistic regression analysis showed M2BPGi as the only independent factor associated with F > 2 and F > 3. Although C-statistics showed that NFS was the best diagnostic factor for F > 2 and F > 3, M2BPGi with NFS had an increased C-statistics value, indicating that it is a better diagnostic model. Conclusions The serum M2BPGi level increased with liver fibrosis severity and could be a good biomarker for diagnosing advanced fibrosis and cirrhosis in NAFLD patients. A well-controlled, prospective study with a larger sample size is needed to validate the diagnostic power of M2BPGi and other fibrosis markers in NAFLD.

Hepatocellular carcinoma (HCC) is one of the most common malignant neoplasms occuring worldwide. Although surgical resection still remains the treatment of choice for HCC, radiofrequency ablation (RFA) has emerged as reliable alternatives to resection. It is less invasive and can be repeated after short intervals for sequential ablation in case of multiple lesions. The most common complication of RFA is liver abscess, and bile duct injury such as bile duct stricture has been reported. This is a case report of a rare complication of abscesso-colonic fistula after RFA for HCC. The case was treated by percutaneous abscess drainage and antibiotics and occlusion of abscesso-colonic fistula with n-butyl-2-cyanoacrylate embolization.

BACKGROUND/AIMS: Performing second look endoscopy has been suggested in order to reduce recurrent bleeding. We assessed whether second look endoscopy reduces the risks of recurrent bleeding and the mortality rate for patients suffering with peptic ulcer bleeding. METHODS: From February 2003 to June 2004, we have performed a prospective, randomized, controlled study of 141 patients with bleeding peptic ulcers, and these patients had been admitted to Kyungpook National University Hospital. Seventy patients in the study group were randomized to receive scheduled second look endoscopy. Seventy one patients in the control group were observed closely. RESULTS: Seventeen of the admitted 141 patients were found to have rebleeding after initial therapeutic endoscopy. The overall rebleeding rate was 12.1%. Although the duration of the hospital stay was significantly lower for the study group than for the control group (p<0.05), the rebleeding rate was similar for both groups (p<0.05). The two groups were similar in respect to the mortality during the period of hospitalization, the volume of hypertonic saline epinephrine that was injected and the number of hemoclips that were used. CONCLUSIONS: From these results, we can conclude that scheduled second look endoscopy with retreatment did not reduce the risk of recurrent bleeding for patients with peptic ulcer bleeding. Therefore, scheduled second look endoscopy should be selectively performed for the patients who are at a high risk for peptic ulcer bleeding.
