In order to evaluate the value of vertebral angiography in assessment of hemifacial spasm, we reviewed retrospectively the vertebral angiography of 28 patients(30 cases) with surgically proved hemifacial spasm but normal CT scans of posterior fossa. There were 9 males and 19 females. Angiography revealed vascular focus of hemifacial spasm located at anterior inferior cerebellar artery, posterior inferior cerebellar artery, and vertebral artery in 19, 9, and 2 cases respectively. Right side was involved in 20 cases. All involved vessels were elongated, tortuous, and dilated. In conclusion, vertebral angiography was valuable in evaluating hemifacial spasm of vascular origin in the posterior fossa.

PURPOSE: The purpose of this study is to evaluate the signal intensity and size of anterior pituitary gland in postpartum women, and to compare with those of control group. MATERIALS AND METHODS: In 34 postpartum women(18-43 years, mean:27 years) and another 35 control nonpregnant women(20-29 years, mean :24 years), midsagittal Tl-weighted MR images were obtained. The signal intensity and height of the anterior pituitary gland were compared between the post-partum and normal control groups. RESULTS: In postpartum women, the signal intensity of the anterior pituitary gland relative to the pons was higher than that of the control gorup. Pituitary gland height of postpartum women was higher(5-11. 8mm, mean:8.18 +/- 1.8mm) than that of control group(2-9mm, mean :6.2 +/- 1.7mm). CONCLUSION: It is concluded that the hyperintensity of the anterior pituitary gland on Tl-weighted image is a normal finding in postpartum women, which is useful in differentiation from pituitary abnormality.

We designed this study to investigate the effects of adenosine on penile erection in Sprague- Dawley rats, in vivo. This was performed by simultaneous monitoring intracavernosal pressure( ICP) and systemic blood pressure with UROCOMPACT 6000 plus( WIEST, Germany) after intracavernosal injection of adenosine, papaverine and adenosine plus papaverine. Increment of maximal ICP was observed in the adenosine treated-group (0.015 to 0.15mg, n=30) in dose dependent manner, i.e., 15.8+/-0.95cmH2O with 0.015mg adenosine to 44.6+/-2.72cmH2O with 0.15mg adenosine, in mean ICP(n=l0, P<0.05). A similar finding was observed in the papaverine treated-group (0.015 to 0.15mg, n =30) in dose dependent manner. i.e., 28.1+/-2.88cmH2O with 0.015mg papaverine to 62.3+/-4.93cmH2O with 0.15mg papaverine, in mean ICP (n=10, P<0.05). The additive effect of adenosine plus papaverine treated-group( 0.015 + 0.015 to 0.15 +0.l5mg, n=30) was to enhance the results obtained by adenosine or papaverine alone in dose dependent manner. i.e., 50.7+/-1.71cmH2O with 0.015mg + 0.015mg papaverine to 79.5+/-5.63cmH2O with 0.15mg adenosine + 0.15mg papaverine. in mean ICP(n= 10, P<0.05). These results suggest that adenosine plays an important role on penile erection in rats. Adenosine may be useful for the future management of impotence, although the clinical effect remains to be investigated.

Priapism is a well recognized complication of some oral medications. Those most commonly cited are: antipsychotic drugs, especially the phenolhiazine: trazodone and chlorpromazine :and the antihyperlensive drugs hydralazine, guanethidine and prazocin. We report a case or priapism associated with the use of chlorpromazine who experienced 2 episodes or priapism and never experience priapism after cessation of the drug.

Suprapubic cystostomy by trocar is a simple, safe and useful method for urinary diversion in acute urinary retention. But rarely, severe complications occur during or after suprapubic cystostomy such as bowel perforation, through and through perforation of the bladder, rectal injury and severe hematuria. We studied the complications of suprapubic cystostomy retrospectively and compared 19 patients who performed ultrasonographic examination with 30 patients without ultrasonographic examination. The complications in 30 patients without preliminary ultrasonographic examination were initial failure in 4 cases (13.3%), extravesical Foley indwelling in 2 cases (6.7%), puncture site closed to the pubic bone in 2 cases (6.7%), spontaneous bladder rupture in 1 case (3.3%) and bowel injury in 1 case (3.3%). But, the complication in 19 patients with preliminary ultrasonographic examination was only 1 retried case (5.3%) because of extravesical Foley indwelling. As above results, the brief preliminary ultrasonographic examination of the bladder is a very useful method with minimal risk during suprapubic cystostomy by trocar.

The ultrasonographic features in 26 cases of blunt testicular trauma were reviewed. Ultrasonography diagnosed correctly in 11 surgically proven cases of testicular rupture. There were three false-positive cases, two with a large scrotal hematocele and one with epididymis rupture. there were no false-negative cases. The sensitivity and specificity of ultrasonographic diagnosis were 100% and 80% respectively. The positive and negative predictive values were 78. 6% and 100% respectively. Therefore, the negative diagnosis by ultrasonography can warrant conservative therapy.

PURPOSE: Our purpose in this study is to evaluate the effectiveness of bronchial and nonbronchial systemic arteries for the control of hemoptysis. MATERIALS AND METHODS: Seventy patients with massive or recurrent hemoptysis underwent percutaneous transcatheter embolotherapy between 1991 and 1993. Retrospectively we reviewed 77 cases of bronchial artery embotization and 32 cases of nonbronchial systemic artery embolization in the 70 patients. RESULTS: Immdiate control of hemoptysis was achieved in 33 of 39 patients with massive hemoptysis(84.6%) and 20 of 24 patients with recurrent hemopt ysis(83.3%). In 32 cases, nonbronchial systemic arteries contributed significantly to areas of pathologic pulmonary tissue and frequently were the major arterial supply. CONCLUSION: Bronchial artery embolization is an effective and life saving procedure in non-surgical candidates. Recognition and occlusion of nonbronchial systemic arteries that feed to hypervascular pulmonary lesions is essential for successful percutaneous embolotherapy of hemoptysis.

A total of 150women with singleton pregnancies who were delivered between 37 and 42weeks gestation had ultrasound scans on elective cesarean section day. The biparietal diameter(BPD), head circumference(HC), abdominal circumference(AC) and femur length(FL) were measured in all cases. Equations of estimated fetal body weight(BWT) for Korean term fetuses using AC alone, BPD/AC, AC/FL, HC/AC/FL, BPD/AC/FL, BPD/HC/AC/FL were made by stepwise multiple regression analysis and were compared with foreign equations such as Campbell(AC), Shepard(BPD/AC), Hadlock I(AC/FL), Hadlock II(HC/AC/FL), Hadlock III(BPD/AC/FL), and Hadlock IV(BPD/HC/AC/FL). The results were as follows. 1. The equations of BWT by sonographic measurement were Equation1 (AC) logeBWT=6.105936+0.005957X(AC) (R=0.876) Equation2 (BPD,AC)logeBWT=6.53614548+0.00004963X(ACXBPD) (R=0.929) Equation3 (AC,FL) logeBWT=6.25336442+0.00751602X(FL)+0.00005155X(ACXFL) (R=0.950) Equation4(HC,AC,FL) logeBWT=6.39631346+0.00004823X(ACXFL)+0.00002023X(FLXHC) (R=0.953) Equation5(BPD,AC,FL) logeBWT=5.99934074+0.00871394X(BPD)+0.00005132X(ACXFL) (R=0.960) 2. When BPD, AC and FL were measured, the addition of HC didn,t affected to accuracy of EFW 3. The best results of all equations were obtained with our equation 5(Mean error=2.36gm, Mean absolute error=96.39gm, Mean deviation + SD(%)=0.07+0.37) and among foreign equations, the best results were with Hadlock III equation(Mean error=18.35gm, Mean absolute error=107.82gm, Mean deviation + SD(%)=-0.46+0.42) 4. The equations using AC/FL (our equation 3, Hadlock I) are more accurate than those using BPD/AC (our equatione 2, Shepard) when utilizing two parameters. Therefore, equation using AC/FL is recommended when the BPD is unobtainable at term or labor 5. The percentage of cases in which the EFW was within +5% and +200gm of the actual birth weight was highest at our equation 5 for 82% and 89%, Hadlock IV equation for 79%, 88%. 6. Our equations had relatively an equal tendency to under- and overestimate fetal weight, but foreign equations, especially Campbell and Hadlock II equations tended to underestimate. 7. Analysing according to actual birth weight, our all equations gave the most accurate estimates of fetal weigh for birth weight group between 3000-3499gm, but for birth weight group above 3500gm, that was not. At birthweight group above 3500gm, the equations depend on femur length are more accurate than the equations independ on fumr length.
