Injuries to the pelvic nerve plexus following major pelvic ablative surgery are commonly observed conditions in urologic field and often related to voiding difficulty with flaccid type of neurogenic bladder. The pathophysiological background for voiding difficulty is unknown and also it is difficult to investigate in human. The present study was undertaken to investigate the functional changes on the bladder and urethra in major pelvic ganglion denervated rats (experimental group). Injury to the pelvic nerve plexus was created by selective removal of bilateral major pelvic ganglions of mature Sprague-Dawley rats (male, 250-300 gm). One week after operation, urodynamic evaluation and NADPH diaphorase histochemistry were performed in each rat. The whole bladder wet weight and residual urine of experimental group significantly increased to 1.6 times and 29 times that of control group, respectively. For urodynamic investigations, the bladder and the urethra were completely disconnected by means of ligation between the bladder neck and the proximal urethra, and simultaneous recordings of the intravesical and proximal urethral pressure were performed. During simultaneous urethro-vesical filling in experimental group, vesical contraction and urethral relaxation were not induced. However, an administration of L-arginine (120 mg/kg intravenously), a nitric oxide substrate, resulted in a gradual decrease in urethral pressure when the bladder pressure was reached at submaximal level. On NADPH diaphorase histochemistry in control group, a large number of NADPH positive nerve fibers were found in the proximal urethra, whereas those were found less commonly in the bladder. In experimental group, the number of NOS positive nerve fibers in the bladder was similar to that in control group. But in the proximal urethra, the number of NOS positive nerve fibers (84.7 +/- 12.7) decreased significantly in contrast to that (185.9 +/- 56.3) in control group. These results indicate that failure to empty in neurogenic bladder may be resulted from relaxation impairment of bladder outlet, which can be explained by the reduction of neuronal NOS in the proximal urethra in experimental group.

Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.

BACKGROUND: Echocardiographically detected left ventricular(LV) hypertrophy is a risk factor for cardiovascular morbidity and mortality. A better understanding of the determinants of LV mass may aid in strategies directed toward the promary and secondary prevention of LV hypertrophy and its consequences. Previous studies have reported that male gender, arterial blood pressure(BP), obesity, age, aortic valvular stenosis, dietary sodium, endocrine factors, and physical activity are positively correlated with LV mass. Of these determinants male gender, hypertension, and obesity are well known but age and blood pressure in healthy adults are controversial. To assess the determinants of LV mass, the relation of 2-dimensional(2D) echocardiographically determined LV mass to body mass inedx(BMI), age, sex, casual BP, and 24 hour ambulatory blood pressure(ABP : systolic, diastolic, and mean BP of 24 hour, day-time, and night-time) was examined in healthy adults. METHODS: The study population consisted of 200 healthy adults who were normotensive, nonobese, and had no evidence of cardiovascular disease(range in age from 20 to 69 years, five decades, 20 men and 20 women per each decade). LV mass was derived from area length method measurements obtained by 2D echocardiography and corrected for height. ABP monitoring was performend over 24 hour(divided into day-time(6am-10pm) and night-time(10pm-6am)periods) with 30 minute inervals. RESULTS: 1) BMI was significantly and independently related to LV mass corrected for height (p<0.001, partial R2=0.31 in men and 0.43 in women). An increase of BMI by 1 kg/m2increased LV mass corrected for height by 1.9g/m in men and 2.0g/m in women. 2) Age was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.15 in men and 0.17 in women). The increments of Lv mass corrected for height per decade were 2.1 g/m in men and 3.4 g/m in women. 3) Gender was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.12), which was greater in men than in women by 6.34g/m. 4) Casual Bp and 24 hour ABP were not significantly associated with LV mass corrected for height in total population and women, and 24 hour systolic BP was significantly related to LV mass corrected for height only in men(p<0.001) with weak partial R2(0.05). CONCLUSION: BMI, age, and male gender were statistically significant and independent correlates of LV mass corrected for height(p<0.001). Maintenance of ideal body weight and normal BP, weight reduction in obese persons and BP control inhypertensive patients may contribute to the primary and secondary prevention of LV hypertrophy and its sequalae.

The adrenocartical carcinoma is a rare tumor with an estimated incidence of 1 case per 1,700,000 population. Despite its rarity, a large number of investigators have studied this neoplasm for the following two reasons. The First is the occasional difficulty of differentiation between careinoma and adenoma at the time of initial surgery, even by histopathologic examination. The other is its unique feature of corticosteroidogenesis. Steroid metabolism of adrenocortieal carcinoma is characterized by its low efficiency of steroid production due to deficiency of steroidogenic enzyme. The deficieney of 11 B-hydroxylase has been indieated in case of adrenoeortical carcinoma by several investigators. In this study, the serum level of cortisol was within normal range, but the serum level of 11-deoxycortisol was 50 times higher than normal. After the removal of tumor, the serum level of ll-deoxycortisol was markedly decm. In conclusion, the results from the this case suggest that measurement of serum 11-deoxy- cortisol may be a useful tool in the diagnosis and follow-up of adrenocortical carcinoma.

The cystic duct syndrome is defined as noncalculous partial mechanical obstruction of the cystic duct with painful gallbladder contraction. In this condition, the gallbladder is able to fill by slow entry of bile from the common hepatic duct, however ejection of bile from the gallbladder is prohibited by partial obstruction of the cystic duct. The main symptom of the cystic duct syndrome is postprandial right upper abdominal pain which oecasionally radiates to back and right shaulder. This sayndrome can be diagnosed by CCK-biliary drainage, CCK-cholecystogram, CCK-cholescintigraphy and ERCP. Since the causes are mechanical, patients with the cyetic duct syndrome are best treated surgically by means of cholecystectomy. We had experienced 2 cases of cystic duct syndrome whose ERCP finding and 24hour delayed film disclosed typical findings. The cholecystectomy was performed and the gross specimen showed narrowed lumen or fibrosis of cystic duct, The symptoms were subsided after cholecystectomy.

The incidence of uterine prolapse during pregnancy is rare. A 34-year-old G3P1 was initially presented at 16 weeks 5days of gestation with a prolapse of the uterine cervix. The cervix was edematous and protruding beyond introitus. Management included bed rest, and the patient was discharged after several days with a vaginal pessary to help maintain cervical placement. At 35 weeks of gestation, the patient did not experience any further prolapse after the removal of the pessary. Pregnancy progressed to term with no further prolapse. She was readmitted at 38weeks 5days of gestation with spontaneous labor. She delivered a 3.36kg male with an Apgar score at 1 minute and at 5 minutes of 7 and 8 respectively. The patient's cervix remained prolapsed in the early postpartum period; however it was easily reduced prior to discharge. After puerperium, the patient's cervix remained prolapsed. She was fitted with a vaginal pessary for uterine support. We reported this case with related literature.

Nine surgically proven congenital absence of gallbladder (CAGB) cases were reviewed. All of them had one or more kinds of biliary symptom. Tests such as abdominal ultrasonography, intravenous or oral cholecystography and even endoscopic retrograde cholangiography not only failed to predict CAGB but misleadingly indicated other similar conditions. Only the abdominal computed tomography (CT), performed on one patient, enabled the accurate diagnosis of CAGB. All the patients underwent abdominal exploration, and CAGB was confirmed by the meticulous dissection of the entire extrahepatic biliary tree and the operative cholangiography. Five patients had concomitant biliary pathologies responsible for their symptoms, but four patients had isolated CAGB. CAGB is a rarely encountered condition for a clinician, but extensive diagnostic work-ups including abdominal CT should be performed in all situations where CAGB is suspected. Thus unnecessary exploration can be avoided in the isolated CAGB case.

PURPOSE: The aim of this study was to evaluate the utility of contrast-enhanced MRI with first-pass and delayed images in prediction of myocardial viability after acute myocardial infarction. MATERIALS AND METHODS: Ten patients (M:F=:4, mean age =6 5 years) with acute myocardial infarction underwent first-pass image after bolus injection of gadolinium (one image/sec for 120sec)and delayed image (7 2 minutes later). According to 60 segments on midventricular level, the assessment of MRI were concerned about location of lesion, depth of lesion, enhancement on first-pass image and enhancement pattern on delayed image. MRI findings were compared with wall motion on resting echocardiography and stress or follow-up echocardiography. RESULTS: 1) MRI findings were classified into 4 types: normal enhancement on first-pass and delayed images (type 1), normal enhancement on first-pass image and nontransmural hyperenhancement on delayed image (type 2), non-transmural enhancing defect on first-pass image and transmural enhancement with endocardial non-enhancing defect on delayed image (type 3), and transmural enhancing defect on first-pass image and transmural hyperenhancement on delayed image (type 4).2) Type 2 suggested viable myocardium and type 3 had high porbability of viability. Type was compatible with non-viable myocardium. CONCLUSION: Enhancing defect on first-pass image and involving thickness on both the first-pass image and delayed image in contrast enhanced MRI may predict myocardial viability.
