Sonographic detection of ureteral jets entering the urinary bladder is a well-known procedure. Color Doppler ultrasound was used to image the ureteral jets in 28 patients with unilateral ureteral calculi proved by intravenous urography. Three major findings of ureteral jets were obtained in the affected ureter with a stone: less frequency (26 patients), weak reflection (20 patients), and lower grade in length (27 patients) that were significantly different from the unaffected side in the same patient. No significant differences were found between the ureteral jets and the degree of hydronephrosis or the location of a stone. In conclusion, these results suggest that ureteral jets should be checked routinely during the procedure of color Doppler ultrasonogram in patients with possible unilateral ureteral obstruction. Color Doppler examination of ureteral jets may be a important adjunct in routine pelvic ultrasonogram especially in patients who have absolute or relative contraindications of intravenous urography.

Paranasal sinus CT is known as the most effective imaging modality in the evaluation of inflammatory sinonasal diseases and can depict the distribution, causative lesions obstructing main drainge route, and associated findings. Recently, functional endoscopic sinus surgery has been widely used for the evaluation and treatment. Before operation, PNS CT has been routinely used to evaluate the paranasal sinuses and mucociliary drainage route. The authors analyzed the PNS CT findings of 3156 cases in 1578 patients with chronic sinusitis symptoms. Sinonasal inflammatory diseases were categorized into 5 patterns according to the obstruction sites. They were 1) infundibular (10%, 316/3156), 2) ostimeatal unit (41%, 1294/3156), 3) sphenoethmoidal recess (12%, 379/3156), 4) sinonasal polyposis (30%, 946/3156) , and 5) unclassifiable (6%, 190/3156) patterns. The main causes for infundibular obstruction in order of frequency were inflammatory mucosa, enlarged ethmoidal bulla and Haller's cell. With respect to the middle meatus obstruction, is main causes in the order of frequency were polypoid lesion, inflammatory mucosa and medially deviated uncinate process. In particular, sinonasal polyposis showed one or more of the characteristic associated findings of infundibular enlargement, air-fluid level, ethmoidal sinus was bulging and bony deossification or sclerosis as well as sinonasal polypoid change. In conclusion, the inflammatory sinonasal diseases were classified into five patterns, and the causative lesions or anatomic variations were efficiently detected by the PNS CT. Furthermore, it could provide a guidance for proper management of the sinusitis including functional endoscopic sinus surgery.

BACKGROUND: We compared thiopental sodium with propofol as induction agents under propofol-N2O anesthesia for cesarean sections. METHODS: We selected 68 pregnant women with a single fetus undergoing an elective cesarean section under general anesthesia and randomly allocated them to the thiopental sodium group (group N) or the propofol group (group P). Without premedication, thiopental sodium 5 mg/kg and succinylcholine 1 mg/kg were injected for induction in group N, and propofol 2 mg/kg and succinylcholine 1 mg/kg in group P. Propofol 10 mg/kg/hr was infused continuously with 50% N2O in both groups. We checked the blood pressure and the heart rate before and after injection. We analysed blood gas of maternal artery, umbilical artery, and umbilical vein at delivery and checked Apgar scores at 1 minute and 5 minutes after delivery. RESULTS: There was no significant difference in blood pressure, heart rate and Apgar scores between groups. Oxygen partial pressure (35.6 +/- 5.8 mmHg) and oxygen saturation (66.2 +/- 12.0%) of the umbilical vein in group P was higher than in group N (32.7 +/- 4.9 mmHg, 58.7 +/- 11.5%). Carbon dioxide partial pressure and pH did not differ between groups. CONCLUSIONS: There was no beneficial effect of thiopental sodium compared with propofol as an induction agent under propofol anesthesia. Propofol is a useful drug for cesarean sections.

BACKGROUND: Pharmacological stress tests for the diagnosis of GH deficiency are unpleasant, labor intensive and potentially dangerous. Reports on urinary GH measurement for the assessment of GH have been published after highly sensitive immunoassaies were developed. The aim of this study was to determine whether a 24- hour urine GH as an alternative method for GH assessment were reliable in predicting GH deficiency defined by L-dopa stimulation test. METHODS: Thirty women, ages 45 to 67, were studied. L-dopa stimulation tests were performed with an ingestion of 500 mg of L-dopa. Serum GH and IGF-1 were measured by a radioimmunoassay using commercially available reagents and uGH was estimated from the 24-hour urine. Then, the mean and its distribution of uGH values were compared according to the GH status defined by L-dopa stimulation test. RESULTS: The correlation between the uGH and the peak values after L-dopa stimulation test was significant (r=0.46; p<0.01). The mean value of uGH in the GH deficiency group was significantly lower than that of the normal group P<0.05). But because of the broad overlap of uGH in the two groups uGH showed no good separation GH deficiency from normal group although uGH reflects GH status significantly. CONCLUSION: uGH reflects GH status significantly, but because of broad overalp uGH couldn't separate GH deficiency form normal group defined by L-dopa stimulation test.

The purpose of this study was to investigate not only the variability in the timing and amount of the maximum pubertal spurt in cranial base and mandible, but also its interrelationship with the timing of peak height velocity. This study was carried out by analysing biannual serial lateral cephalometric radiographs of twenty-six males and twenty-one females who were taken from 8.5years to 16.5years old of mean age, according to the established land-marks and linear measurements. The results of this study were summarized as follows. 1. Prevalance of the maximum growth spurt more than 80 percentage was occurred in all measurements of cranial base and mandible, except posterior cranial base length in the female. 2. In all measurements of cranial base and mandible, the maximum spurt was occurred earlier in the female than the male while it was greater in male in all measurements except ramal height. 3. In body height measurement, the peak height velocity was occurred 2 years earlier for the female(11.0 years old) than the male(13.0 years old). 4. The timing of maximum spurt in anterior cranial base length and total mandibular length in both sexes and ramal height in the female were coincided with PHV. The maximum spurt was occurred in both sexes in all measurements 2 years before or after PHV, except mandibular body length and posterior cranial base length the in female. 5. In all ages, there was significant correlation between th etotal mandibular length and ramal height, and was also correlation between total cranial base length and anterior cranial base length(P<0.05). However, there was no significant correlation between the ramal height and mandibular body length. In addition, there was also no any correlation between the anterior cranial base length and posterior cranial base length in all ages(P>0.05).

OBJECTIVE: To evaluate whether twin discordancy is a risk factor for adverse perinatal and neonatal outcomes. METHODS: Three hundred and seventy-five twin gestations over 28 weeks of gestation were included in this retrospective study. Medical records of mothers and infants were reviewed. Pregnancies were divided into 2 groups according to the birth weight discordancy(%) between twin neonates(group I;less than 25%, group II;25% or more). Birth weight discordancy was calculated from following formula; (birth weight of larger twin-birth weight of smaller twin)/birth weight of larger twin x 100. Perinatal and neonatal outcomes in group I and II were compared with each other. Also, difference in the outcomes between the smaller and larger twins of group II was evaluated. To evaluate whether birth weight discordancy is an independent variable in predicting poor perinatal and neonatal outcomes, multiple logistic regression analysis was used. RESULTS: Thirty-seven gestations(9.9%) were documented to belong to group II. Group II showed significantly higher incidence of preeclampsia, placenta previa, and small for gestational age infants(p<0.01, p<0.05 and p<0.001, respectively). The group also showed higher incidence of adverse neonatal outcomes(admission to neonatal intensive care unit, respiratory distress syndrome, pneumonia, bronchopulmonary dysplasia, patent ductus arteriosus, intraventricular hemorrhage, retinopathy of prematurity, necrotizing enterocolitis, sepsis, congenital anomaly, neonatal death, p<0.01). Outcomes of the larger and smaller twins of group II were not significantly different with each other except small for gestational age infants(p<0.005). However, birth weight discordancy was not an independent variable in predicting adverse perinatal and neonatal outcomes. CONCLUSION: Fetal growth discordancy of 25% or more should be regarded as a risk factor for adverse perinatal and neonatal outcomes in twin gestations. However it is not an independent factor in predicting adverse perinatal and neonatal outcomes.
