3.The Relationship between Optical Coherence Tomography and Scanning Laser Polarimetry Measurements in Glaucoma.
Korean Journal of Ophthalmology 2006;20(4):225-229
PURPOSE: To investigate the relationship between optical coherence tomography (OCT) and scanning laser polarimetry (SLP) in measuring peripapillary retinal nerve fiber layer (RNFL) thickness in glaucomatous eyes. METHODS: Fifty glaucomatous eyes were evaluated in this study. Evaluations were analyzed two ways. First, parameters of the Stratus OCT (average thickness, superior/ inferior average) and GDx VCC (TSNIT average, nerve fiber indicator (NFI), superior/ inferior average) were correlated using the Pearson's correlation coefficient (r). Secondly, comparison (r) of these parameters was completed using the mean deviation (MD) of visual field defect. RESULTS: The following parameters were found to be significantly correlated (P<0.005). TSNIT average/average thickness (r=0.673), NFI/average thickness (r=-0.742), superior average (r=0.841), and inferior average (r=0.736). In the correlation analysis using the severity of visual field defect, all these parameters had statistically meaningful correlations (P<0.005). CONCLUSIONS: GDx VCC and Stratus OCT are highly correlated in glaucomatous eyes. Therefore, peripapillary RNFL thickness measured by Stratus OCT and GDx VCC may be equally helpful in the diagnosis of glaucoma.

BACKGROUND: CD34 is a 115 kD glycoprotein which is expressed on hematopoietic progenitor cells. It is also known as an immunohistochemical marker of endothelial cells. OBJECTIVE: This study was designed to investigate the patterns of CD34 expression on: (1) cutaneous benign and malignant vascular tumors and (2) on the mature and immature vessels of pyogenic grauloma and capillary hemangioma. METHOD: We performed immunoperoxidase staining using a monoclonal anti-CD34 antibody (QBEND/10) on formalin fixed, paraffin-embedded sections of 23 benign and malignant cutaneous vascular tumors. RESULTS: The results are summerized as follows: 1. In 3 cases of nevus flammeus and 6 cases of carvernous hemangioma, vascular endothelial cells of all hemangiomas showed CD34 expressions. In 5 cases of angiokeratoma, endothelial cells of hemangioma, did not express CD34. 2. In all 5 cases of pyogenic granulomas and one case of capillary hemangioma, endothelial cells of mature vessels, endothelial cells near the well-formed lumina and endothelial cells showing intracellular lumina showed strong positivity for CD34, wbile endothelial cells far from the lumina and endothelial cells without lumina formation mostly showed negative staining for CD34. 3. One cese of Kaposis sarcoma showed focall positivity for CD34 both in endothelial cells of the small, well-formed vessels and spindle cells. Two cases of angiosarcoma showed CD34 expression only in endothelial cells of well-formed, normal appearing vessels, whereas atypical endothelial cells of tumor vessels and spindle cells were negative for CD34. CONCLUSION: CD34 could be a marker for endothelium in mature, well-differentiated vascular structures and may serve as a marker of lumen formation or differentiation of endothelial cells.

5.Mitomycin C Trabeculectomy for Refractory Glaucoma: A Comparison between 0.25 and 0.5mg/ml of Mitomycin C.
Journal of the Korean Ophthalmological Society 1996;37(1):143-153
To determine the optimum concentration of mitomycin C(MMC) in patients with refractory glaucoma undergoing trabeculectomy, we retrospectively examined 31 eyes of 22 patients with refractory glaucoma who underwent trabeculectomy with 0.25mg/ml MMC for 5 minutes. They were case matched with a group of 36 eyes of 28 patients who had undergone trabeculectomy with 0.5mg/ml MMC for 5 minutes by using age, gender, type of refractory glaucoma, preoperative intraocular pressure(IOP), and preoperative medications as variables. MMC was applied between the sclera and Tenon's capsule during trabeculectomy, and scleral flap was closed with tight releasable sutures. No statistically significant differences were found in mean IOP between the two groups at the one, three, six, and nine months postoperative periods. The mean follow-up was 9.3 months in the 0.25mg group and 9.8 months in the 0.5 mg group(p=0.70). At the last postoperative visit, 81%(25 eyes) in the 0.25mg group and 86%(31 eyes) in the 0.5mg group had an IOP less than 21mmHg with or without glaucoma medication(p=0.79). At the last postoperative visit, there were no statistically significant differences in mean IOP(17.2 +/- 8.6mmHg and 17.2 +/- 7.3mmHg, respectively, p=0.99), mean number of medications(0.6 +/- 0.9 and 0.5 +/- 0.7, respectively, p=0.77), and change in visual acuity(3 eyes and 6 eyes lost more than 2 lines of vision, respectively, p=0.75) between the two groups. The incidence of complications were similar between the two groups. Our data suggests similar efficacy and safety in trabeculectomy with 0.25 and 0.5mg/ml MMC for 5 minutes.

In order to investigate the validity of the Steel's gluteus medius and minimus advancement, we reviewed 21 hips in 14 spastic cerebral palsy patients, who had advancement of the gluteus medius and minimus insertion for the correction of in-toeing gait between November 1985 and February 1992. The procedure was limited to those patients who had moderate to severe in-toeing gait with positive Steel's stretch reflex. There were eight boys and six girls. The average age at the time of surgery was 6.7 years(2.9 years-11.9 years). The procedure was performed on both hips in seven patients. Of the 14 patients, nine had diplegia, three hemiplegia, and two paraplegia. The average follow-up time was 4.3 years(1 year-8.5 years). In-toeing gait was converted to neutral or physiologic out-toeing gait in 17 hips(81%), excessive out-toeing in 2 cases(9.5%), and mild residual in-toeing in 2 cases(9.5%), Steel's stretch reflex, which was present in all cases preoperatively, disappered in 19 hips(90.5%) postoperatively, Abductor power, however, decreased from 4+ to 4− in average postoperatively, Among the 16 hips, which had no Trendelenburg sign or gait preoperatively, 8 hips(50%) showed positive Trendelenburg sign and gait postoperatively. In conclusion, Steel's gluteus medius and minimus advancement appears to be effective in the correction of in-toeing gait, but there is high risk of weakening the abductor power.

H2-receptor blockers are widely used for therapy of peptic ulcer disease and gastroesophageal reflux disease. H2-receptor blockers infrequently cause adverse hepatic effects, and when they occur they are usually asymptomatic. There are several previous reports of liver injury related to ranitidine. Until now, only two cases of acute hepatitis associated with the use of famotidine were reported in the world. We report three cases of clinical hepatitis that followed administration of famotidine (2 cases) and ranitidine (1 case). First, a 54-year-old woman received famotidine, 40mg, daily for treatment of erosive gastritis. After 6 weeks of treatment with famotidine, jaundice and itching sense developed. Second, a 45-year-old man was hospitalized for jaundice. He had a long history of duodenal ulcer and had been intermittently treated with famotidine. He had 6 weeks of treatment with famotidine prior to admission. Third, a 19-year-old woman was hospitalized for nausea, vomiting and urticaria. She had a history of acute hepatitis B virus infection and was discharged 4 weeks prior to readmission. She had been received ranitidine, 300 mg, daily for treatment of gastritis. After 17 days of drug ingestion, whenever she had taken her medication, she developed these symptoms of nausea, vomiting and urticaria. Other causes of hepatitis were ruled out and all patients recovered after discontinuation of drug ingestion.
