Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.

Two kinds of copper-pure and 70% dilute alloy suspension were introduced into the vitreous of albino rabbits, and electron microscopical observation was carried out on the retinal tissue after several periods from 1 day up to 60 days. Major changes are as follows: 1. Early response of rabbit retina with pure copper foreign body exhibited severe and diffuse destruction with much deposition of particles mainly in nerve fiber layer. The influence of 70% copper alloy to the retinal tissues tended to demonstrate mild, localized and delayed in occurrence. 2. In the nerve fiber layer where the tissue disintegration took place Muller cell demonstrated the features of mitosis and proliferation. Including this rare incidence, it is possible to conclude that Muller cell proliferation occur in any part of the retina if the condition allows. 3. Cytoid bodies mainly consisting with glycogen aggregates within the Miiller cell processes in nerve fiber layer was one of prominent pictures in early stage. 4. Muller cells took an important role in reparative process replacing the destructive portion of the retinal cells with the extension of the same cells beyond the external limiting membrane toward the choroid. 5. At the late stage, the Muller cells contained abundant filaments replacing the reduced number of smooth surfaced endoplasmic reticulum and other organells. That implicats the enhancement of supportive mechanism at the occasion of the disintegration of retinal tissue prolonged. 6. A relatively early sign was active phagocytosis of retinal pigment epithelial cells engulfing the reminiscent fragment of ouer pigment of visual cells.

To predict the mydriatic status of the cataract patients preoperatively, we performed maximal mydriasis test with stepwise instillations of 1% tropicamide and 2.5% phenylephrine or 10% phenylephrine to the out-patients who was scheduled to have cataract operation. Among 210 eyes of 113 patients, the pupillary size of 167 eyes was dilated to 8mm or more and the other 43 eyes were insufficiently dilated to less than 8mm diameter. In the insufficiently dilated group, we have observed the presumable causes of insufficient mydriasis as follows: posterior synechiae, diabetic autonomic pupillopathy, age-related miosis and unknown. By this test, we could predict the mydriatic status of the cataract patient preoperatively and could prepare the appropriate operative method and equipment effectively.

OBJECTIVE: Our purpose was to complete delivery during daytime through rapid and safe management with oral prostaglandin plus oxytocin, and to reduce the duration of induced labor, hospital stay and dispersion of human power. METHODS: Ninety pregnancies requiring induction of labor between December 1998 and July 1999 were analyzed prospectively. Patients were assigned to receive either oral PGE2 or oral PGE1. In one group, labor induction was performed with 0.5 mg of oral PGE2 (group 1, n=46), was orally taken every one hour since 06:00 AM to 09:00 AM and intravenous oxytocin infusion (The beginning dose was 2 mU/min, the dose increased by 2 mU/30 min) beginning at 09:00 AM, and in the other group (group 2, n=44), 100 microgram of PGE1 was orally taken at 11:00 PM the day before oxytocin infusion was commenced at 07:00 AM. If there was uterine contraction of more than 200 Montevideo units, intravenous oxytocin would not be given. RESULTS: The mean time (+/-standard deviation) to active phase labor (cervical dilatation more than 3 cm and uterine contraction more than 200 Montevideo units) with PGE2 group was 335.16+/-157.89 minutes versus 534.16+/-211.79 minutes with PGE1 group (P<0.001). The mean time from active phase to birth was 182.8+/-93 minutes in group 1 versus 236.4+/-88.8 minutes (P<0.001). These significances were due to the difference of time interval from taking prostaglandins to infusion of oxytocin between the two groups. The time zone of expected delivery was 13:28 PM to 15:48 PM and 10:22 AM to 13:18 PM (Confidence Interval 95%). The induction failure rates were 10.87% versus 9.09%. The induction failure rate was significantly different according to Bishop score (if <4, 15.3% versus if >or= 4, 0%) and the cesarean section rate was also (if < 4, 40.7% versus if >or= 4, 19.4%) in the two groups (P<0.05). There were no clinical or statistical differences in demographic data, clinical characteristics, maternal outcomes and complications, and neonatal outcomes. CONCLUSION: Both may be proper methods of inducing delivery during daytime and begun at outpatient office base.

In order to evaluate the effects of incision location and suture method on induced astigmatism in cataract surgery, three different procedures were applied to 150 eyes which had phacoemulsification through 6 mm incision with 6 mm optic IOLs. The group 1(50 eyes) had posterior limbal incision followed by interrupted radial sutures. The group 2(50 eyes) had posterior limbal incision followed by continuous shoelace sutures. The group 3(50 eys) had scleral pocket incision at 2 - 2.5 mm apart from the surgical limbus followed by sutureless technique. The corneal astigmatism was ana lysed by algebraic and vector methods. Keratometric astigmatic changes with vector analysis on postoperative 1 day were 2.34 diopter(D), 1.41D, 0.74D in the group 1, group 2, gruop 3 respectively. There were statistically significant differences among the three groups(p<0.01). At postoperative 1 week. the keratometric astigmatic change of the group 3 was less than that of the group 1(p<0.01) and the visual acuity of the group 3 was better than that of the group 1(p<0.05). During postoperative 1 to 6 months, there was no statistically significant differences among the three groups in astigmatic changes or visual acuity. It could be concluded that scleral pocket incision with suture less technique showed significantly less astigmatism than other techniques initially, and continuous shoelace suture technique could have more stable and less astigmatism than interrupted radial suture technique.

Systemic hypotension is commonly observed in association with the administration of protamine after cardiopulmonary bypass. To elucidate the circulatory changes and arterial blood gas changes of protamine sulfate administration, we studied 27 patients following cardiopulmonary bypass. In the intraaortic protamine administration group (N=5), the mean arterial pressure decreased significantly (p<0.05) in 5 minutes during protamine infusion and after protamine, infusion respectively. Heart rate, central venous pressure and blood gas analysis did not change significantly. In intravenous protamine administration group (N=22), the arterial oxygen tension increased significantly(p<0.05 %amp; p<0.01) in 10 minutes during protamine infusion and after protamine infusion respectively. There were no special changes when the more than 0.3mg/kg/min rate of protamine was injected but the mean arterial pressure decreased significantly(p<0.05) in 5 minutes during the protamine infusion. Mean arterial pressure, heart rate, central venous pressure and blood gas analysis did not change in the less than 0.3mg/kg/min rate of protamine was injected. There were no circulatory changes in the less than one hour CPB time group but the arterial oxygen tension increased significantly in 5 minutes and 10 minutes during the protamine infusion and after the protamine infusion. But in the more than one hour CBP time group, the mean arterial pressure decreased significantly in 10 minutes during the protamine infusion and after protamine infusion.

OBJECTIVE: To evaluate the clinicopathologic features and clinical outcomes of adnexal tumors in pregnancy. METHODS: After review of charts of 51 patients managed at Kyungpook National University Hospital from January 1996 to June 2002, data including clinical findings, treatments and outcomes were analyzed. RESULTS: The mean age of pregnant women with adnexal tumors was 28.5 years old and the adnexal tumors were more common in nulliparous pregnant women (74.5%) than parous those. There were asymptomatic or no signs in 40 cases (78.4%), lower abdominal pain in 9 cases (17.6%), vaginal bleeding in 1 case (2.0%) and palpable mass by patient herself in 1 case (2.0%). The surgical treatments were performed at first trimester in 9 cases (19.1%), second trimester in 31 cases (66.0%) and third trimester in 7 cases (14.9%). Postoperative histopathologic diagnoses of adnexal tumors were 22 cases (43.1%) of benign cystic teratoma, 7 cases (13.8%) of functional cyst, 6 cases (11.8%) of serous cystadenoma, 4 cases (7.8%) of mucinous cystadenoma, 4 cases (7.8%) of endometrioma, 3 cases (5.9%) of parovarian cyst and 4 cases (7.8%) of malignancy including 2 cases of mucinous cystadenocarcinoma and 2 cases of mucinous tumor, borderline. The complication resulting from adnexal tumors was torsion of 6 cases (11.8%). The outcome of pregnancy was available in 30 cases, term delivery in 25 cases (83.3%), preterm delivery in 3 cases (10%) and spontaneous abortion in 2 cases (6.7%). CONCLUSION: Although the incidence of adnexal tumors with pregnancy is variable according to the reports, the detection rate is more and more increasing due to a widespread application of ultrasound. Thus, obstetricians must always consider adnexal tumors combined with pregnancy and try to minimize the complications of surgery during pregnancy to prevent adverse fetal outcome and maternal morbidity.
