Intramural implantation is among the rarest forms of ectopic pregnancy.Since the first description by Perli, 21 cases were reported in worldwide literatures.The pathologic criteria required for intramural pregnancy is that the product of conception is completely surrounded by uterine musculature and is separated from the uterine cavity and the fallopian tube or round ligament.The previous history of uterine injury or adenomyosis is known as possible etiology of intramural implantation. Because the early diagnosis is very difficult, most cases is found after onset of complication such as a uterine rupture or hemoperitoneum. We have recently experienced a case of intramural pregnancy diagnosed and treated by laparoscopy in a 9 weeks gestation nulliparous woman without previous history of uterine injury or disease, and report with a brief review of literatures.

p53 is a tumor suppressor gene product identified in a wide range of tumor including colorectal carcinoma. Genetic alterations in the p53 tumor suppressor gene are common in human colorectal carcinoma. bcl-2 is a protooncogene that inhibits apoptosis. The products of mutant p53 gene and bcl-2 have been associated with prognosis in several malignancies including colorectal carcinomas. This study was undertaken to evaluate values of p53 and bcl-2 oncoproteins as prognostic factors relative to clinicopathological factors and correlation of their expression. Analyses were made on achieval pathologic tissues of 80 patients with colorectal carcinomas including 34 patients able to follow-up over 5 years. The oncoproteins were localized using commercially available monoclonal antibodies:DO-7 for p53, clone124 for bcl-2. Expression of bcl-2 was cytoplasmic, whereas nuclear p53 expression was localized in carcinoma cells. The patients were 17 to 83 years of age. The expression of p53 and bcl-2 was determined respectively in 30 (37.5%) and 21 (26.3%)cases. The expression of p53 nuclear expression was not correlated with tumor location, size, histologic grade, Duke's classification, regional lymph node metastasis and tumor recurrence. The cytoplasmic expression of bcl-2 was not correlated with tumor location, size, histologic grade, Duke's classification, regional lymph node metastasis and recurrence. Univariate analysis showed that patients with p53 nuclear expression were not associated with poorer overall survival than patients with p53 negative, and also showed in patients with bcl-2 expression. The expression of p53 did not affect to that of bcl-2. We concluded that the p53 nuclear and bcl-2 cytoplasmic expression were not independent prognostic factors in colorectal carcinomas. Evidence of reciprocity of bcl-2 and p53 expression was not found.

BACKGROUND: We evaluated the current status of diabetes management and the predictors for poor glycemic control in an urban area. METHODS: This study included 1,138 community-dwelling adults (> or =50 years) with diabetes, of which 584 participated in the diabetes care survey. Logistic regression was used to identify the factors predicting poor glycemic control (hemoglobin A1c[HbA1c]> or =7%) in the total sample and to evaluate the relationship between the history of diabetes management checkup and poor glycemic control in the diabetes care survey sample. RESULTS: Of the 1,138 patients, 53.2% had blood pressure less than 130/80 mmHg, 41.7% had fasting glucose between 70 and 130 mg/dL, 48.6% had HbA1c below 7.0%, 60.1% had triglycerides below 150 mg/dL, 41.4% had low density lipoprotein cholesterol below 100 mg/dL, and 59.1% had normoalbuminuria (urine albumin-to-creatinine ratio <30 mg/g creatinine). Of the 584 patients completing the diabetes care survey, 63.9% had one or more lipid tests, 32.0% had one or more HbA1c tests, 43.8% had one or more microalbuminuria tests, and 42.5% had one or more fundoscopic examinations annually. Female gender (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.23-2.36), duration of diabetes (OR, 1.07; 95% CI, 1.06-1.09), and alcohol use (OR, 1.40; 95% CI, 1.06-1.85) were associated with an increased risk for poor glycemic control while age (OR, 0.97; 95% CI, 0.96-0.99) and antihypertensive medication (OR, 0.64; 95% CI, 0.50-0.83) were associated with a decreased risk. CONCLUSIONS: This study shows that glycemic control is likely to be poor in urban areas. We need to develop appropriate community-based strategies to achieve optimal glycemic control and prevent diabetes complications.

PURPOSE: This study was designed to determine the validity and usefulness of laser oximetry in measuring changes in penile hemodynamics for assessment of erectile function. MATERIALS AND METHODS: Anesthetized male New Zealand White rabbits (3.5~4.0 kg) were divided into two groups and penile hemodynamics were assessed by either laser oximetry (total hemoglobin, oxyhemoglobin, deoxyhemoglobin concentration and oxygen saturation) or intracavernosal pressure (ICP) monitoring before, during and after penile erection induced by pelvic nerve stimulation (PNS) or intracavernosal administration of phentolamine (0.05~1.0 mg/kg), nitroprusside (1~30ng/kg), papaverine (0.1~1.0 mg/kg) or sildenafil (3~150ng/kg). ICP recordings were normalized to systemic systolic arterial pressure. RESULTS: PNS caused significant frequency-dependent increases in penile ICP. PNS also caused significant increases in penile tissue hemoglobin (total and oxy) concentrations and tissue oxygen saturation in a frequency-dependent manner. These changes were correlated with frequency-dependent increases in ICP. The duration of recorded responses (changes in hemoglobin concentration or ICP) increased with increasing frequency of nerve stimulation. Intracavernosal administration of phentolamine, nitroprusside, papaverine and sildenafil produced significant increases in ICP, tissue hemoglobin, oxygen saturation and duration of response as a function of increasing drug concentration. CONCLUSIONS: Laser oximetry permits reproducible and valid assessment of changes in penile hemodynamics comparable to classical intracavernosal pressure measurements. Thus, we consider laser oximetry a reliable technique in evaluating penile hemodynamics. Its sensitivity in detecting small changes in oxyhemoglobin concentration and its non-invasive nature makes it advantageous over invasive METHODS such as intracavernosal pressure monitoring and laser Doppler flowmetry.

PURPOSE: Arteriovenous fistula at the wrist has remained the procedure of choice for long-term chronic hemod ialysis since its development by Brecia and Cimino in 1966. Thrombosis is the most common cause of early failure after arteriovenous fistula procedure, should be reconized preoperatively or intraoperatively, but no consensus exits regarding the ideal preoperative or intraoperative screening method for access surgery. We describe a simple intraoperative maneuver that can be used to detect proximal stenotic vein segments. METHODS: From September 1998 to September 1999, a total of 117 arteriovenous fistulas were performed for permanent hemodialysis in patients with chronic renal failure. Of them, a intraoperative evoked thrill test was performed in 61 patients (A group), in 56 patients (B group or control group) was not. RESULTS: Early failure rate (<30 days) was 12.5% in A group, 9.8% in B group or control group. In this study, the specificity and positive predictive value of the evoked thrill test was 100%, indicating that this maneuver is highly accurate in predicting early failure. CONCLUSION: Evoked thrill test is a simple and useful intraoperative method for improving the patency rate of autologous arteroiovenous fistula.

PURPOSE: To compare the safety and effectiveness of transarterial oily chemoembolization (TOCE) and transar-terial embolization (TAE) with Gelfoam in cases of ruptured hepatocellular carcinoma (HCC), and to describe the most important prognostic factors involved in emergency embolization. MATERIALS AND METHODS: Forty-two consecutive patients with spontaneously ruptured HCC underwent emergency TOCE (n = 22) or TGE (n = 20). In the TOCE group, Lipiodol (3 -10 cc), Adriamycin (20 -50 mg), and Mitomycin (2 -10 mg) were used, and these were followed by blockade of the hepatic arterial flow with gelatin sponge particles. In the TAE group, patients underwent only Gelfoam embolization. Using the Kaplan-Meier method, survival time from the time of embolization was estimated, and to analyze prognostic factors, Cox 's proportional hazard regression model was used. RESULTS: Successful hemostasis was achieved in 41 patients (97.6%). Mean survival time was 201 and 246 days in the TOCE and TAE group, respectively, but the difference was not tatistically significant (p > 0.05). Five of the TOCE group (22.7%) and three of the TAE group (15.0%) died of hepatic failure. Analysis of the prognostic factors showed that portal vein involvement by the tumor was the most important factor influencing survival. CONCLUSION: Although TOCE and TAE effectively controlled hemorrhaging from a ruptured HCC, the procedures involve a high risk of hepatic failure. Their goal should, therefore, be solely to achieve hemostasis, and thus decrease parenchymal injury.

Pheochromocytomas are catecholamine-producing tumors that typically cause hypertension. They are rare tumors that can pose problems in diagnosis and detection. Although they usually present classic symptoms, they can at times present symptoms that mimic other clinical conditions. Especially, children have fewer malignant tumors, non-extra-adrenal tumors, and tumors with greater bilaterality and multiplicity. The diagnosis of pheochromocytomas is based upon clinical suspicion and biochemical study. Radiologic localization is obtained before operation because of the variable location of this tumor. The treatment of choice is surgical resection. We reports a case of asymptomatic pheochromocytoma that was treated with tumor excision. To prevent intraoperative and postoperative complications, precise preoperative diagnosis and localization, as well as adequate preoperative management, are necessary.

The laparoscopic cholecystectomy is now a standard part of general surgical practice. Conversion from a laparoscopic cholecystectomy to an open cholecystectomy is sometimes required. To identify the factors predisposing to conversion, we retrospectively reviewed all patients undergoing a laparoscopic cholecystectomy from December 1991 to June 1996 at Chosun University Hospital. Factors evaluated were age, sex, history of acute cholecystitis, previous abdominal surgery, associated disease, laboratory findings, and thickened gallbladder wall identified by preoperative ultrasound. Conversion to an open cholecystectomy was required in 42(9.0%) of the 465 patients. The most common reason for conversion was the inability to define the anatomy secondary to inflammation or adhesions. Significant predictors of conversion to an open cholecystectomy were increasing age (age over 60 years), presense of associated disease, a thickened gallbladder wall found by preoperative ultrasound, acute cholecystitis, and increased alkaline phosphatase level. Multivariate analysis found a patients age of over 60 years to be an independent predictor of conversion to an open cholecystectomy. An appreciation for these predictors of conversion will allow appropriate planning by the patients, the institution, and the surgeons. Although data are lacking, increasing experience with laparoscopic cholecystectomy has likely resulted in earlier recognition of the need for conversion to an open cholecystectomy with a resultant decrease in morbidity.

PURPOSE: Fournier's gangrene is a rapidly progressive fulminant infection of the perineum and abdominal wall along with the scrotum in men and the vulva in women. If the effective surgical treatment is delayed, the patients result in fatal. Modern surgical series report a mortality of 8-67%. Objective: The aims of this study were to examine the outcomes of 20 consecutive patients with Fournier's gangrene caused by a perianal abscess and to identify the factors leading to improved survival in these patients. METHODS: The medical records of all patients who had been treated at Chosun University Hospital between January 1991 and December 1999 for Fournier's gangrene caused by a perianal abscess were retrospectively reviewed. RESULTS: Twenty patients were identified (mean age 47 years, range 20-66). The sexual ratio was 2.3:1 (male:female). The etiologies included perianal fistula (35%), unknown (35%), hemorrhoidectomy (10%), rectal cancer perforation (10%), and injection therapy (10%). Associated conditions included diabetes mellitus (50%), liver cirrhosis (10%), pulmonary tuberculosis (5%), intestinal tuberculosis (5%), ulcerative colitis (5%), Crohn's disease (5%) and iron deficiency anemia (5%). Escherichia coli and bacteroid fragilis were most commonly identified. All 20 patients initially received multiple incisions and debridement. At the time of first surgery, a diverting colostomy was required in 35% of the cases and a ileostomy in 5%. Over the past 10 years, the survival rate of patients with Fournier's gangrene caused from perianal abscess has been high (100%). CONCLUSION: The keys to a successful outcome included early diagnosis, prompt surgical intervention with radical debridement, prompt fluid resuscitation, rapid initiation of broad-spectrum antibiotics, and hemodynamic support in an intensive care setting.
