PURPOSE: The aim of this presentation is to analyze the factors influencing on retrograde insertion of double-J catheter in urethral obstruction due to malignancy and to predict the possibility of stunting with double-J catheter. MATERIALS AND METHODS: A retrospective analysis of 43 patients who had underwent retrograde double-J catheter insertion for urethral obstruction secondary to pelvic malignancy, from January 1993 to April 1997, was performed to evaluate the success rates of double-J ureteral stenting according to the factors such as age, sex, presence or absence of flank pain, degree of hydronephrosis, renal function, stage of tumor, laterality of ureter, past history of radiotherapy, operation and chemotherapy. RESULTS: According to the degree of hydronephrosis, the success rate was 100, 73.7 and 50% in grade I II and III, respectively(p<0.05). According to the renal function, the success rate was 81.3% in the group with normal renal function and 45.5% in the group with abnormal venal function(p<0.05) According to the stage of disease, the success rate was 100, 70.7 and 58.3% in stage I, II and III, respectively. According to the absence or presence of flank pain, the success rate was 56.3% in the group with flank pain and 81.5% in the group without flank pain. According to the past history of radiotherapy, the success rate was 65.6% in the group treated with radiotherapy and 90.9% in the group not treated with radiotherapy. The age, sex, laterality of ureter, past history of operation and chemotherapy were not significantly correlated to the success rates. CONCLUSIONS: The factors influencing on double-J ureteral slanting were the degree of hydronephrosis, renal function, absence or presence of flank pain, stage of disease and past history of radiotherapy Further study will be needed to demonstrate the accurate timing of urethral stenting with doublets ureteral catheter.

Bacterial infection has been implicated in premature labor in human. But it is impossible to undergo human study of bacteria-induced preterm delivery. If we carry out animal experiment which simulate human preterm delivery induced by bacteria, studies for mechanism, diagnosis, and treatment of preterm delivery will be progressed rapidly. To elucidate mechanisms and potential intervention strategies in preterm pregnancy loss, we observed bacteria-induced preterm labor and the protecting effect of administration of antibiotics with hysteroscopy-guided intracervical inoculation of Escherichia coli. Sterile saline solution(group I, n=5) or 2x10(7)cfu (colony-forming units) of E. coli bilaterally in the cervix of pregnant New Zealand White rabbits on day 20 or 21(70% of gestation) by hysteroscopy was inoculated and rabbits were assinged to ampicillin-sulbactam therapy beginning at 0hr(group II, n=4), 2 hr(group III, n=4), 4 hr(group IV, n=2), and 16 hr(group V, n=2) after inoculation with E. coli, or to no antibiotic therapy(group VI, n=3). Unasyn(ampicillin-sulbactam) was used and its daily dosage was 100 mg/kg/day. The occurrence of vaginal bleeding or preterm birth was observed every two hours. If one rabbit fetus was found to be delivered, exploratory laparotomy was done. Amniotic fluid culture on each sac, decidual culture on each uterine cavity, and pathologic examinations on each placenta were done. The results of experiments are as follows. In control group(0.2cc sterile saline inoculation only), there was no preterm labor and no bacterial growth in culture. In all three rabbits in group VI, preterm delivery occurred and the culture results were all positive in maternal blood, decidua, and amniotic sacs. Preterm delivery also occurred in group V, but results of maternal blood culture were all negative. Increased trend in the occurrence of preterm delivery was statistically significant in the order(p < 0.05) : group I(0/5), group II(0/4), group III(0/4), group IV(0/2), group V(2/2), and group VI(3/3). Pregnancy outcomes on the basis of the number of living fetus, dead fetus, and macerated fetus, have significant trend in the above order. Amniotic fluid culture results also had significant relationship(p < 0.05) : group I(0.20), group II(20/26), group III(18/30), group IV(10/11), and group VI(7/7). In group V, amniotic fluid fail to be obtained due to severe oligohydramnios. Decidual culture results also had an increased trend; group I(0/32), group II(21/29), group III(20/30), gorup IV(16/16), gorup V(11/11), and group VI(25/25). It is statistically significant(p < 0.05) Incidence of histologic chorioamnionitis was also significantly increased from group I to VI. These results indicate that E. coli inoculation has induced preterm delivery and antibiotic therapy has somewhat prevented preterm birth, amniotic fluid infection, decidual infection, and histologic chorioamnionits. Antibiotic effects were attenuated in cases of delayed antibiotic administration.

OBJECTIVE: Acute inflammatory lesions in the placenta is one of the most common histopathologic lesions of women with preterm premature rupture of membrane. But there is a few scientific evidence to support the association between amniotic fluid white blood cell count and the presence and severity of acute placental inflammation in preterm premature rupture of membrane. To evaluate the relationship between amniotic fluid white blood cell count and the presence and severity of acute placental inflammatory lesions in preterm premature rupture of membrane. METHODS: The relationship between amniotic fluid white blood cell count and placental histologic finding was examined in 89 consecutive patients who were admitted with the diagnosis of preterm premature rupture of membrane and who delivered singleton gestation within 3 days. RESULTS: The prevalence of acute histologic chorioamnionitis was 68.5%(61/89) and that of positive amniotic fluid culture was 32.6%(29/89). The prevalence of positive amniotic fluid culture increased according to the higher severity of inflammation in each type of placental section(p<0.05 for each). The median amniotic fluid white blood cell count increased significantly according to the presence and higher severity of inflammation in each type of placental section(p<0.01 for each). The median amniotic fluid white blood cell count increased significantly according to the higher total grade of inflammation in placental histologic examination(p<0.01). CONCLUSION: Both the presence and higher severity of acute histologic chorioamnionitis are associated with an elevated amniotic fluid white blood cell count. The total grade of acute histologic chorioamnionitis is associated with an elevated amniotic fluid white blood cell count. Amniotic fluid white blood cell count is a reliable prenatal marker of histologic chorioamnionitis."

Subretinal fluid drainage produces the indentation of the sclera by facilitating firm adhesion between the retina and either retinal pigment epithelium or Bruch's membrane and has the advantage that show the state of fundus and degree of indentation of sclera accurately during the operation. Becaulse it has complications such as choroidal bleeding, retinal incarceration, iatrogenic retinal break, choroidal detachment and loss of vitreous, it should be done carefully. The authors analyzed the clinical data of 128 cases(137 eyes) of retinal detachment surgery with subretinal fluid drainage at the Department of Ophthalmology, Pusan Paik Hospital, College of medicine, Inje University from May, 1988 to April, 1990. And the results were as follows: 1. The most common operative method of rhegmatogenous retinal detachment were explant buckling and encirclement with subretinal fluid drainage, and the success rate of first operation was 86.13% and the overall success rate of rhegmatogemous retinal detachment was 91.2% in 137 eyes of operation. 2. In 116 cases(92.8%) who were done subretinal fluid drainage, absorption of residual subretinal fluid took in a day. 3. The most common cause of surgical failure was proliferative vitreoretinopathy. 4. The most common complication was choroidal hemorrhage and it was developed 14 eyes(10.2%) mong 137 eyes. 5. The preoperative duration of symptom and extent of detachment were influenced to the surgical success rate and they had statistical significance(p<0.05). 6. The power of refraction was changed to myopia and ERG b-wave amplitude were increased and 89 eyes out of 137 eyes(69.6%) showed an improvement of vision at the three months after retinal detachment surgery.

Aspirin(ASA) and NSAIDs can induce bronchoconstriction in 10~20% of adult asthmatics patients. Inhalation of lysine-ASA(L-ASA) has been described as an alternative method for diagnosis of ASA-sensitive asthma. To further understand the characterlstics of ASA-sensitive asthmas. we studied 38 asthmatic patients with ASA -sensitivity (36 intrinsic and 2 extrinsic asthma) proven by L-ASA bronchoprovocation test (BPT). Most were female (male to female ratio was 27:73). Twenty (53%) of them had no previous history of adverse reactions when exposed to ASA. Twenty nine (79%) had rhino-sinusitis symptoms. Early asthmatic response was observed in 16 (42%) patients, late only response in 16(42%), and dual response in 6(16%) patients. The threshold of L-ASA to provoke a positive response ranged from 11.2 to 180 mg/ml and most (68.3%) had a positive response after the inhalation of 180 mg/ml. Concurrent sensitivity to sulfite was noted in 14 (36%) patients, followed by sensitivity to tartrazine in one (3%) patient. None showed a positive response to sodium benzoate. After the avoidance from ASA/ NSAIDs with administration of anti-asthmatic medications, symptom and medication scores reduced in 26(87%) patients among 30 followed patients. They were classified into the improved group: four (13%) patients belonged to the not-improved group. There were no significant differences in clinical characteristics between the improved and not- improved group (p>0.05). In conclusion, L-ASA BPT could be considered as a useful method to diagnose ASA -sensitive asthma and be used to screen the causative agent for asthmatic patients with intrinsic type, especially in female patients with rhino-sinusitis and/or nasal polyp, even though they do not have arty history of adverse reactions. Cessation of exposure and proper treatment may allow to reduce symptom and medication scores.
