Mitomycin C (MMC) trabeculectomy combined with extracapsular cataract extraction and posteor chamber intraocular lens implantation (glaucoma triple procedure, 30 eyes) was clinically compared with MMC trabeculectomy alone (30 eyes). The age, type of glaucoma, and preoperative number of medications were matched with the previous group (P>0.05). The mean preoperative intraocular pressures (IOPs) were 30.2+/-8.3mmHg (range, 22~56mmHg) in the glaucoma triple procedure group and 31.6+/-8.9mmHg (range, 22~57mmHg) in the trabeculectomy alone group (p=0.55). The mean postoperative IOPs were significantly higher in the glaucoma triple procedure group compared with the trabeculectomy alone group at all postoperative vistis (one month to nine months) (p<0.05). However, there were no statistically significant differences in the mean number of postoperative rise exceeding 30 mmHg within the postoperative one month tended to occur more frequently in the glaucoma triple procedure group (7 eyes (23%)) than the trabeculectomy alone group (2 eyes(7%)) (p=0.13). Conjunctival filtering blebs were significantly frequently observed in the trabeculectomy alone group than the glaucoma triple procedure group (28 eyes (93%), 20 eyes (67%), respectively, P=0.02) at 6 months postoperatively. The common postoperative complications were hyphema (4 eyes) and posterior capsular opacification (4 eyes) in the glaucoma triple procedure group and shallow anterior chamber(4 statistical difference was noted between these two groups (p>0.05). Although hypotensive effect of MMC on the glaucoma triple procedure was less than on the trabeculectomy alone, glaucoma triple procedure using MMC could be recommended to be safe and effective on controlling the high IOP for treating glaucoma patients with coexisting cataract.

Malignant tumors of the maxilla represent about 3-4% of head and neck malignant neoplasm and the origins are maxillary gingiva, hard palate and maxillary sinus. We are to investigate clinical features and results according to various treatment modalities of maxillary malignant tumor to get information for better treatment results. Sixty patients with malignant maxillary tumors treated at Yonsei medical center from 1992 to 1997 were studied retrospectively. They are evaluated according to clinical signs & symptoms, stages at first diagnosis, primary site, histopathologic features, treatment method, recurrence and survival rate with clinical records, biopsy results and CT radiograph. The most common primary site was maxillary sinus and most common histopathology was squamous cell carcinoma. The local recurrence rate was 18% at 5 years, neck failure was 3% and distant metastasis was 18%. Overall survival rate was 78% at 2 years and 69% at 5 years. Failure at primary site is the main problem in the curative treatment. So, to improve survival in these patients efforts should be directed toward improvement of local control.

This study was performed to identify the expression of neurofilament in sensory nerve of human cornea. The three normal corneal tissues were dissected. Monoclonal antibody to neurofilament protein were used to visualize the corneal nerve. The one normal cornea was examined to observe the corneal nerve with electron rnicroscope. Transmission electron rnicroscope showed that the corneal nerve contained the neurofilament within the axon. The indirect iinmunofluorescent techniques revealed the expression of neurofilament in corneal stroma. The results of this study show that immunofluorescent technique may useful method in identification of sensory nerve of human cornea, and make it easy for us to visualize corneal innervation pattern in flat section by using of antibody to neurofilament protein.

Attempts to quantify the parameters of optic nerve head structure have been made to recognize the earliest structural abnormalities in glaucoma, and to efficiently monitor the structural changes of the optic nerve head with advancing disease. Optic disc parameters were measured in 88 normal subjects and 149 primary open-angle glaucoma patients using a computer graphic program (Adobe photoshopTM) and the photographic magnification was corrected according to Littmanns method. The sensitivity, specificity, and predictive value of optic disc parameters were calculated to discriminate between normal and glaucomatous eyes at different stages of glaucoma. Receiver operating characteristics curves were used for comparisons of different disc parameters. In the group with mild glaucomatous visual field (VF) defects (mean deviation (MD); better than -5dB, group 1), optic disc parameters did not provide greater sensitivity and specificity enough to detect early glaucomatous optic nerve head damage. In the group with moderate VF defects (MD; -6~-10dB, group 2) and advanced VF defects (MD; worse than -11dB, group 3), the minimum rim width within the 60 sector across the vertical meridian (predictive value; 84.4%, 95.9%, respectively), vertical cup to disc ratio (83.7%, 95.2%, respectively), and rim area to disc area ratio (83.7%, 95.1%, respectively) were helpful to identify the glaucomatous eyes, whereas horizontal cup to disc ratio (77.3%, 90.3%, respectively) and cup area (75.2%, 89.0%, respectively) were less helpful in this regard.

OBJECTIVE: To evaluate the effects of piroxicam patch(Trast) in rheumatoid arthritis patients with knee joint pain and swelling and to determine the concentration of plasma and synovial fluid following patch application. METHODS: Twenty-two patients with rheumatoid arthritis participated in a double-blind, placebo-controlled study. The patients were instructed to apply piroxicam or placebo patch at one knee and re-apply it every other day for 2 weeks. They had washout period for 2 weeks and then applied the other patch for 2 weeks at the same joint. The patients recorded knee joint pain using visual analog scale. Knee joint swelling and tenderness were assessed before and after application of piroxicam and placebo patch. Complete blood count, AST, ALT, BUN, creatinine, joint fluid analysis were also done. Piroxicam concentration in plasma and synovial fluid were measured by high performance liquid chromatography(HPLC) after 2 weeks of piroxicam patch application. RESULTS: Knee joint pain improved significantly after the application of piroxicam patch for 2 weeks(visual analog scale, 56. 2+5. 9m vs 48. 2+5. 7mm, p=0. 03 by Wilcoxon signed rank test). There was no significant change in white cell count of synovial fluid, peripheral blood cell count, chemistry, C-reactive protein and erythrocyte sedimentation rate. In terms of adverse effects, mild gastrointesti nal disturbance(8/21 cases, 38%) and local side effects such as pruritus and ery thema(3/21 cases, 14%) were developed, which were insignificant compared with control groups(30%, 15% respectively). Piroxicam concentrations in plasma and synovial fluid after the application of piroxicam patch were 0. 129+0. 04ug/ ml (mean+SE) and 0. 644+0. 202ug/ml respectively. CONCLUSIONS: Piroxicam patch is a safe and effective therapeutic modality for knee joint pain in patients with rheumatoid arthritis. Mild adverse effects such as gastrointestinal disturbance and local side effects were noted. Piroxicam concentration was higher in synovial fluid than in plasma following the application of piroxicam patch.

The passive immunization of pregnant female rats to S-100 protein often leads to ultra-structural abnormalities in the brain glial structures of the offspring of these rats and induces signs of delayed development in the fetal brain. Additionally passive immunization of pregnant animals with certain antigens induces permanent Ag-specific changes in the immune response of their offspring. The purpose of this study was to investigate serum immunoreactiviy (SIR) to S-100 in cerebral-palsied and developmentally-delayed children as well as in their healthy parents and to evaluate its significance related to radiologic findings of brain MRI and single photon emission computed tomography (SPECT). The subjects were children with cerebral palsy and delayed development that had abnormal findings on brain MRI or Brain SPECT. SIR to S-100 protein was measured by ELISA method in the patients, their healthy parents, 20 normal adult controls and 22 normally developed children. The SIR to S-100 protein was significantly higher in the cerebral-palsied and developmentally-delayed children when compared to that of the normal control group children. Increased SIRs were detected in healthy mothers but not in their fathers. There was no difference of SIR between the cerebral-palsied and developmentally-delayed children or any significant difference of SIRs according to the findings of the brain MRI or to developmental quotients. But, the SIRs to S-100 protein were higher in the group of more abnormal findings on brain SPECT.

OBJECTIVES: The aim of this study is to enhance understanding the clinical features, pathogenesis, diagnosis and treatment of gouty arthritis in Korea by analyzing the clinical manifestations of the patients with urate crystal-proven gouty arthritis. METHODS: 78 cases who had been diagnosed as gouty arthritis by confirming the urate crystals in synovial fluids or tophi in Seoul National University Hospital between January 1, 1989 and July 31, 1995 were analysed for their histories, symptoms, signs, laboratory data, and X-ray findings. RESULTS: 1) Male to female ratio was 18.5:1. The mean age of onset is 49.3 +/- 14.5 years(range 11-83 years); the mean duration of disease 6.5 +/- 7.0 years(range 0-30 years); the mean duration of gouty attack 7.2 +/- 5.5 days(range 1-30 days). 2) The frequent precipitating factors of gouty arthritis were hospitalization(37%) and alcohol drinking(15%). The most frequent accompanying disease was hypertension(24%). Obesity, diabetes, chronic renal failure, hyperlipidemia, ischemic heart diseases, or cerebrovascular diseases were also accompanied by gouty arthritis. 3) The patterns of joint involvement were devided into 3 groups: monoarthritis; 42%, oligoarthritis; 35%, polyarthritis; 23%, The most frequent site of the first gouty attack was the 1st toe(65%). The most frequently involved joint at gouty attack was also the 1st toe(68%). While only lower extremities were involved in most cases with monoarthritis and oligoarthritis(91% and 78%, respectively), both lower and upper extremities were involved in most cases with polyarthritis(78%). 4) Hyperuricemia was found in 74% of the cases at gouty attack. But serum uric acid level was normal in 26%. With respect to pathogenesis of hyperuricemia, 14% of the cases had uric acid overproduction and 86% had uric acid underexcretion. 5) Bony changes in radiologic findings were found in 47% of the cases and tophi in 33%. Bony changes and tophi was significantly related to the younger age of gouty onset and higher serum uric acid level at gouty attack. 6) Acute gouty arthritis responded well to colchicine and NSAIDs. There was no difference in efficacy and the frequency of side effects between them. CONCLUSION: The clinical features of the gouty arthritis in Korea showed no difference from those in foreign studies except higher prevalence of oligo-/polyarthritis and tophi. To be remarkable, 26% of the patients with gouty arthritis did not have hyperuricemia at gouty attack. This finding indicates that urate crystals should be confirmed by synovial fluid examination for diagnosis of gouty arthritis.

Clinical evaluation and imaging studies such as magnetic resonance imaging, computed tomography, and/or myelography can localize the pathologic process in most patients with lumbar radiculopathy. However, these studies occasionally fail to demonstrate exactly the cause and site for ongoing radicular symptom. So we evaluated 54 patients for the efficacy of selective nerve root blocks to identify a symptomatic nerve. The lumbar nerve root injections were performed at L3 root in 1 patients, at L4 root in 4 patients, at L5 root in 46 patients, and at S1 root in 3 patients. Among them, forty two patients were done before operation(HNP 32, stenosis 5, spondylolisthesis 5), 9 patients were done after operation due to poor results (root injury 2, infection 2, adhesion 1, incorrect diagnosis 4), and 3 patients had improved radiculopathies following nerve root injection(HNP 2, stenosis 1). The results of the nerve root injections and of the operations were not affected by age and sex. There was a good correlation between the response of the nerve root injection and the result of the operation(p<0.05). The concentration of bupivacaine 0.5% has no additional effect comparing to 0.25%(70%/73.5%) solution in spite of its adverse effect causing transient motor weakness. Additional use of depomedrol(50mg) proved to be no more beneficial. Three patients had Improved symptoms for a long period after nerve root injection which consequently made operation unnecessary. Five patients with previous history of operations had moderate pain relief. In summary, lumbar nerve root injection can be used as a functional diagnostic tool to predict operative result and as a treatment modality following failure of a previous surgery.

To identify the pattern of glaucomatous changes of the optic disc, the rim area to disc area ratio (RA/DA ratio) of 149 eyes (149 cases) with primary open-angle glaucoma (POAG) were measured and compared with that of 88 eyes (88 cases) of normal individuals. At all stages of the disease, glaucomatous rim loss was present in all sectors of the optic disc. The location of the most pronounced rim loss changed depending on the severity of the disease. In the early (RA/DA ratio > 61%; mean deviation(MD): -6.43+/-3.32dB) and medium (RA/DA ratio=41~60%; MD: -7.54+/-5.65dB) glaucoma subgroups, rim loss was found predominantly at the inferior temporal and superior temporal disc region. In the advanced glaucoma subgroup (RA/DA ratio=40~21%; MD: -18.27+/-8.40dB), the temporal horizontal disc region showed relatively marked rim loss. In the far advanced glaucoma subgroup (RA/DA ratio=20~0%; MD: -25.91+/-5.40dB), the rim remnants were located mainly in the nasal disc sector, with a larger rim portion in the upper nasal region than in the lower nasal region. These results indicate that generally in POAG, the loss of neuroretinal rim was found to start predominantly in the inferior temporal and superior temporal disc region, and then the temporal horizontal, the inferior nasal, and the superior nasal disc sectors followed.
