This study was undertaken to evaluate the outcome of combined phacoemulsification, intraocular lens implanation, and trabeculectomy with Mitomycin C. We reviewed 39 eyes in 36 consecutive cases who had been undergone triple procedure for coexisting cataract and glaucoma from January 1993 to October 1995 at Chonnam university hospital. The mean follow-up period was 8. 8 months. Preoperatively, most patients had a visual acuity of worse than 0.4, but the visual acuity improved postoperatively in 20 eyes (51.0%) achieving the visual acuity better than 0.5 at 6 months after the surgery. The mean preoperative intraocular pressure was 31.1 +/- 12.9mmHg, and the mean postoperative IOP was 16.5 +/- 5.4mmHg at 6 months follow-up. The mean number of antiglaucoma medication was 1.87 preoperatively, and 0.28 postoperatively. The postoperative complications were posterior capsular opacity (7 eyes), hyphema (2 eyes), shallow anterior chamber (3 eyes), transient hypotony without macular edema (2 eyes). There was no statistically significant difference in intraocular pressure control at different concentration of Mitomycin C (0.2 and 0.4mg/ml). We conclude that the use of Mitomycin C in combined procedure provides good short-term(6 months) results regarding intraocular pressure control and visual recovery.

BACKGROUND: Morphine has been commonly used for postoperative pain control. We measured plasma concentrations of morphine and compared the efficacy and safety of continuous epidural analgesia (CEA) using morphine-bupivacaine with intravenous patient controlled analgesia (IV-PCA) with morphine for 48 hrs after the end of the operation. METHODS: Nineteen patients undergoing Mile's operation were assigned to receive a morphine loading dose of 5 mg followed by IV-PCA with 0.1% morphine (IV-PCA group, n = 9) or a morphine loading dose of 2 mg and 0.125% bupivacaine 10 ml, followed by CEA with 0.004% morphine and 0.075% bupivacaine at a rate of 5 ml/hr (CEA group, n = 10). The plasma concentrations of morphine were measured and visual analog scales (VAS) for pain were recorded at 1, 6, 12, 24, and 48 hr postoperatively and the effects on respiration and any other side effects were noted. RESULTS: The mean maximal and minimal levels of plasma morphine were 40.2 +/- 21.2 ng/ml and 23.4 +/- 9.7 ng/ml for the IV-PCA group and 11.8 +/- 3.5 ng/ml and 8.2 +/- 1.9 ng/ml for the CEA group, respectively. Resting and dynamic pain scores were significantly lower in the CEA group than in the IV-PCA group. There were no significant differences for the effects on respiration and for any side effects between the two groups. CONCLUSIONS: We evaluated plasma concentrations of morphine with CEA using morphine-bupivacaine and IV-PCA using morphine for the postoperative pain control. The CEA group had better postoperative analgesia than that of the IV-PCA group and the incidence of side effects were not significantly different between the two groups.

In order to see whether the binocular patching with cycloplegia improves the prognosis in the treatmet of traumatic hyphema, we studied prospectively 77 patients with nonperforating traumatic hyphema who were admitted and treated at the Chonnam University Hospital between January 1994 and July 1995. We analyzed the clearance time of blood clot in the anterior chamber, the incidence of rebleeding and the final visual acuity. The patients were divided into four groups : group I, of 17 patients treated by monocular patching ; group II, of 19 patients treated by monocular patching with cycloplegia ; group III, of 20 patients treated by absolute bed rest with binocular patching ; group IV, of 21 patients treated by absolute bed rest with binocular patching and cycloplegia. The average clearance time of blood clot was 7.4 days in group I, 7.4 days in group II, 6.9 days in group III and 7.5 days in group IV. The incidence of rebleeding was 5.8% (n=1) in group I, 10.5% (n=2) in group II, 0% (n=0) in group III, 14.3% (n=3) in group IV. The final visual acuity of 0.6 or better was achieved in 10 patients (58.8%) of group I, 13 patients (68.4%) of group II, 13 patients (65.0%) of group III, 14 patients (66.7%) of group IV. In the treatment of traumatic hyphema, binocular and monocular groups as well as cycloplegic and non-cycloplegic groups showed no significant difference from each other in the clearance time of blood clot, incidence of rebleeding and the final visual acuity.

Hydroxyapatite has been reported as an excellent orbital implant for good prosthetic motility without implant migration or protrusion. We performed hydroxyapatite orbital implantation in 102 patients between January 1992 and December 1995 ; 52 cases (50.8%) of evisceration, 43 cases (42.2%) of enucleation and 7 cases (7.0%) of secondary implantation for the better prosthetic motility. We performed 99mTc-MDP bone scan in 77 patients between 4 and 16 months (mean: 7.6 months) postoperatively. The 69 patients (89.6%) revealed radiotracer uptake over grade II. The 75 patients of 81 patients excellent cosmesis with satisfactory prosthetic motility. Conjunctival wound dehiscence were observed in 51 patients (50.0%) ; in 30 cases of evisceration, in 19 cases of enucleation, and in 2 cases of secondary implant. And hydroxyapatite implant exposure were developed in 17 patient (16.7%) ; in 14 cases of eviseration (82.4%) and 3 case of enucleation (17.6%). And 8 patients of exposed hydroxyapatite were healed spontaneously and another 4 patients are under observation to expect the wound dehiscence to heal spontaneously. Exposed hydroxyapatite implants with more than 5mm in diameter were managed with dermis graft in two cases, scleral patch graft in two cases and oral mucosal graft in one case. Hydroxyapatite orbital implant needed higher cost and longer duration until the full treatment, but it gave an excellent cosmetic reconstruction without any extrusion or unacceptable infection.

The branchiogenic anomalies are common congenital cervical anomalies. They usually arise from an incomplete obliteration of the branchial apparatus during fetal development. These anomalies may be confused with and mistaken for other potentially more serious lesions, such as cystic hygromas, teratomas, and lymphomas. The anomalies are typically discovered in the pediatric and adolescent population and develop unilaterally. Bilateral manifestations are very rare and have a familial tendency. In addition, anomalies such as intrauterine and postnasal growth retardation, premature aging and unusual faces may be related with bilateral occurrence. This is the first report in the Korean language literature of bilateral branchial fistulas.

Because of the excellent cosmetic and functional reconstruction compared with other integrated implant, hydroxyaptite is commonly used in recently. This excellent cosmetic effect is acquired by successful integration between hydroxyapatite and normal orbital tissue by fibrovascular tissue. We performed simultanously magnetic resonance imaging and bone scan to two patients undergoing hydroxyapatite orbital implantation after evisceration and evaluating fibrovascular ingrowth into the implant between MRI and bone scan and observed ingrowing pattern of fibrovascular tissue into the hydroxyapatite after evisceration especially. MRI studies are somewhat more valuable imaging than bone scan. Vascularization into the implant were started from inserted portion of extraocular muscle and posterior aspect of implant and slowly progressed to the center of hydroxyapatite sphere. There was no relation between inserted duration and fibrovascular ingrowth due to individual variation. And constrast enhanced MRI appears to be the best imaging method for evaluating the hydroxyapatite orbital implant and its fibrovascular ingrowth. In spite of low specificity compared with MRI, bone scan is also valuable method for the evaluating vascularization of the hydroxyapatite because of low cost and easy follow-up.

PURPOSE: The aim of this study was to compare the prostate volume, as measured by transrectal ultrasonography (TRUS) and by MRI, with that of the real prostate volume measured after a radical prostatectomy (RRP). MATERIALS AND METHODS: This prospective study included 21 clinically localized prostate cancer patients that had undergone a RRP. TRUS prostate volumes were calculated using the prolate ellipsoid volume formula, with the anteroposterior diameter measured from the axial (TRUS_V1) and midsagittal images (TRUS_V2). Two prolate ellipsoid volumes (MRI_EV1 and MRI_EV2) were calculated from the MRI using the same method, and planimetric volume (MRI_PV) with 3D image software. The real prostate volume (Real_V) was measured in a measuring jug within 1 hour after RRP. RESULTS: The average age and preoperative serum prostate-specific antigen (PSA) were 65.5 years (54-70) and 6.8ng/ml (2.5-17.0), respectively. Mean of Real_V, TRUS_V1 and TRUS_V2 were 40.3ml (21.0-82.0), 42.4ml (23.8-82.2) and 51.4ml (29.1- 87.3), respectively. The mean of MRI_EV1, MRI_EV2 and MRI_PV were 44.2ml (17.9-85.2), 41.0ml (15.7-93.9) and 40.9ml (19.4-83.8), respectively. In a paired sample test, the correlation coefficients (R) for all methods used were over 0.8. In a Student's t-test (paired), the MRI_PV (p=0.620), MRI_ EV2 (p=0.703) and TRUS_V1 (p= 0.099) showed no significant differences compared to the Real_V. The linear regression models of this three methods were y=1.025x 0.268, y=0.946x 2.979 and y=1.046x 0.381, respectively. CONCLUSIONS: Between the TRUS prolate ellipsoid volumes, the TRUS_V1 was shown to be superior to the TRUS_V2. In the MRI, the MRI_EV2 was more accurate than the MRI_EV1. However the MRI_PV was the most accurate method. The TRUS_V1, MRI_EV2 could be used instead of the MRI_PV in general clinical settings.
