PURPOSE: This study investigated the influence of patent ductus arteriosus (PDA) and its treatment on incidence and progression of retinopathy of prematurity (ROP). METHODS: The authors retrospectively reviewed the medical records of 408 infants who underwent screening examinations for ROP at the Neonatal Intensive Care Unit of our hospital. RESULTS: The total incidence of ROP was 23.5% (96 out of 408) and the patients that needed treatment were 7.4% (30 out of 408). The mean birth weight and gestational age was 1406.1 grams and 30.67 weeks in patients without ROP, and 979.8 grams and 27.46 weeks in patients with ROP, respectively. In both total and very low birth weight (VLBW) patients, the incidence of ROP was higher in the PDA group than the non-PDA group, but the PDA group was an independent risk factor only in the VLBW group (p = 0.033). The incidence of threshold disease was not significantly different between the PDA and control groups (p = 0.757). There was no significant difference of incidence of ROP and threshold disease among the 3 treatment groups for PDA. CONCLUSIONS: In VLBW patients, the presence of PDA increased the risk of ROP and its progression, thus more attention is needed for PDA patients. However, there was no significant difference in ROP incidence and progression according to different PDA treatment methods.

The purpose of this study was to evaluate the material for fixed type retainer, allowing physiologic tooth movement. and proper remodeling of periodontal tissue during retention period. The present study was performed to observe the histologic changes of periodontal tissue after application of different types of fixed type retainer after orthodontic tooth movement in young adult dogs. For this study, 4 young adult dogs were used as a experimental animal and experimental group was divided into three groups ; experimental group 1 contained right side maxillary third incisors and canines, experimental group 2 contained contralateral teeth of same animals, and control group contained mandibular premolars. And each dogs were applied the 4 different types of fixed type retainer to experimental group 1. The experimental teeth were ligated on the Sentalloy closed coil spring(R)(Tomy Co., Japan) from maxillary third incisors and canines and applied orthodontic force at initial 200gm-forced during 1 week. All the experimental animals were sacrificed on the 3rd week after the orthodontic teeth movement and then the specimens were taken, fixed in formalin, embeded in parafin, sectioned 6-8micrometer in thickness and stained with Hematoxylin-Eosin staining, and Masson's trichrome staining method. Examined under the light microscopy. The following results were observed. 1. There were observed that decreased infiltration of giant cells in pressure side and increased the new bone forming in tension side on the specimen of 6-stranded 0.0195' Respond(R)(G&H Co., U.S.A.) group. Periodontal ligament fibers were much compressed or elongated in 3-stranded 0.018', 0.020' Dentaflex(R)(Dentarum Co., Germany), and Superbond C&B(R)(Sun Medical Co., Japan) groups. 2. In experimental group 1, necrotic bone inside the alveolar bone of pressure side, forming of the sharpey's fiber in osteoid tissue, and remodeling of the periodontal ligament were observed in all animals. 3. In experimental group 2, it was observed that the amount of bone resorption was equal or decreased in pressure side, and increased new bone forming and significantly decreased infiltration of giant cell than the experimental group 1. By this results, it considered that 6-stranded Respond(R)(G&H Co., U.S.A.) wire was the most useful material allowing early periodontal tissue remodeling.

PURPOSE: We report a case of late opacity of an AT LISA intraocular lens after vitrectomy in a diabetic patient.CASE SUMMARY: A 61-year-old man presented with blurring in the left eye. He had undergone bilateral phacoemulsification and intraocular lens implantation 6 years ago, and vitrectomy with SF₆ gas tamponade in the left eye due to rhegmatogenous retinal detachment 3 years ago. The patient was diagnosed with pre-existing diabetes, hypertension, and coronary heart disease. Examination of the left eye showed round and centrally located whitish fine granular deposits on the surface of the intraocular lens, and zonular rupture from the 3 to 6 o'clock position. The intraocular lens in the right eye was clear. The corrected vision was 0.9 in the right eye and 0.5 in the left eye. The intraocular lens was explanted from the left eye together with the capsular bag, and was examined under light microscopy, histochemical analysis, and with scanning electron microscopy equipped with an energy dispersive X-ray spectroscopy detector with light element capabilities. CONCLUSIONS This study was the first to report late postoperative opacity in the multifocal intraocular lens, AT LISA 809M. The possibility of intraocular lens opacity in patients with underlying disease or in those undergoing vitrectomy should be explained prior to corrective procedures.

PURPOSE: The purpose of this study was to evaluate the systemic effects of ranibizumab and bevacizumab by examining the plasma levels of anti-vascular endothelial growth factor (anti-VEGF) and VEGF before and after a single intravitreal injection. METHODS: Twenty-eight eyes of 28 patients with various retinal diseases were enrolled. Seventeen eyes received an injection of intravitreal bevacizumab, and 11 eyes received an injection of ranibizumab. Blood samples were collected just before and 1 day, 1 week, and 1 month after injection. Concentrations of anti-VEGF and VEGF in plasma were measured using enzyme-linked immunosorbent assay (ELISA). RESULTS: In the bevacizumab group, anti-VEGF concentration before the injection was 91.0 ng/mL, while those at 1 day, 1 week, and 1 month post-injection increased to 153.6, 196.3, and 140.3 ng/mL, respectively (p < 0.05 for all). VEGF concentration before the injection was 93.9 pg/mL, while those 1 day, 1 week, and 1 month post-injection were reduced to 40.1, 24.7, and 33.5 pg/mL, respectively (p < 0.05 for all). However, in the ranibizumab group, no significant reductions in anti-VEGF concentration were observed. The anti-VEGF concentration before the injection was 177.6 ng/mL, while those at 1 day, 1 week, and 1 month post-injection were 177.5, 160.7, 175.3 ng/mL, respectively (p > 0.05 for all). VEGF level also showed no significant change. VEGF concentration before the injection was 80.9 pg/mL, while those at 1 day, 1 week and 1 month post-injection were 96.7, 106.3, 106.1 pg/mL, respectively (p > 0.05 for all). CONCLUSIONS: Contrary to ranibizumab, intravitreal bevacizumab significantly lowers plasma VEGF level in patients with various retinal diseases. The study suggests the consideration of the systemic effects of intravitreal bevacizumab injection.

PURPOSE: To compare the clinical 3 months postoperative results of three different 1-piece aspheric intraocular lenses (IOLs): AcrySof IQ SN60WF (Alcon Laboratories, INC, Fort Worth, TX), TECNIS 1-piece ZCB00 (AMO Inc., Santa Ana, CA) and the newly developed enVista MX60 (Bausch & Lomb, Rochester, NY). METHODS: In a total of 62 eyes, 1 of the 3 1-piece aspheric IOLs, AcrySof IQ SN60WF, TECNIS 1-piece ZCB00 or enVista MX60 was implanted after cataract extraction. Best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and spherical equivalent were assessed 3 months postoperatively. Total spherical aberration, high order aberration, and modulation transfer function were analyzed. RESULTS: There were no significant differences of UCVA, BCVA, the accuracy of postoperative refractive power, and modulation transfer function among the 3 IOLs. Higher order aberrations of the entire eye and internal optics showed almost no significant differences. CONCLUSIONS: The newly developed IOL, enVista MX60, showed equivalent clinical outcomes as both AcrySof IQ SN60WF and TECNIS 1-piece ZCB00.

PURPOSE: To report the results of a clinical comparison study of a prophylactic new generation fluoroquinolone (FQs; levofloxacin 0.5%, gatifloxacin 0.3% and moxifloxacin 0.5%) topical antibiotic regimen administered prior to intraocular microsurgery. METHODS: From May 2007 to April 2010, Trial 1, 214 eyes of 211 patients scheduled for intravitreal injection were randomized into one of three FQ-treated groups or the control (non-treated) group. Patients who were randomized into FQ-treated groups were treated with eye drops containing one of three FQ antibiotics (levofloxacin 0.5%, gatifloxacin 0.3% and moxifloxacin 0.5%) preoperatively four times a day for three days before surgery. The rate of positive bacterial cultures from conjunctival scrapings were assessed and compared. Trial 2, 159 eyes of 159 patients scheduled for cataract surgery were randomized into one of three FQ-treated groups, and treated with eye drops as same method in trial 1. The concentration of antibiotics in the anterior chamber of the eye were measured and compared. RESULTS: The positive bacterial culture rates of trial 1 were 48.9%, 38.3%, 23.4% in the levofloxacin-treated group, the gatifloxacin- group, and the moxifloxacin-treated group, respectively. These rates were all significantly lower than the 70.2% positivity rate observed in the control group. Average antibiotic residue concentrations in the aqueous humor measured in trial 2 were 0.37 +/- 0.49 microg/ml in the levofloxacin-treated group, 0.31 +/- 0.37 microg/ml in the gatifloxacin-treated group and 0.59 +/- 0.72 microg/ml in the moxifloxacin-treated group. These concentrations were not significantly different. There were no reported side effects during the study period. CONCLUSIONS: Eye drops containing new generation FQ antibiotics instilled three days before microscopic ophthalmic surgery can be used safely and effectively for the prevention of postoperative endophthalmitis.

OBJECTIVES: Attention deficity hyperactive disorder is known to be a disease with a high genetic trait. Recently the relationship between alleles frequency distribution and ADHD has been actively researched. In Korea, the relationship between the genetic type and alleles for dopamine transporter gene has been studied in ADHD patients. METHODS: Thirty five patients diagnosed with ADHD according to the DSM-IV diagnostic criteria were selected for study. The diagnosis and clinical features were confirmed by korean version Child behavior check list, korean version Conner's parent rating scale, Attention deficit Diagnostic System, korean version Spielberger state-trait anxiety scale etc. For the control group, the parents of patients were chosen. Blood samples were taken from the 105 subjects. DNA was extracted from blood lymphocytes, PCR was performed for dopamine transporter gene. RESULTS AND CONCLUSION: In comparing the ADHD transmitted group and the not transmitted group, significant difference was seen between the DAT1 genetic type and alleles distribution. As a result, it is viewed that there is relationship between ADHD and the dopamine transporter gene. Follow up studies with larger patient or pure subgroups are expected.

BACKGROUND: The root of Peucedanum japonicum Thunb., a perennial herb found in Japan, the Philippines, China, and Korea, is used as an analgesic. In a previous study, sec-O-glucosylhamaudol (SOG) showed an analgesic effect. This study was performed to examine the antinociceptive effect of intrathecal SOG in the formalin test. METHODS: Male Sprague-Dawley rats were implanted with an intrathecal catheter. Rats were randomly treated with a vehicle and SOG (10 µg, 30 µg, 60 µg, and 100 µg) before formalin injection. Five percent formalin was injected into the hind-paw, and a biphasic reaction followed, consisting of flinching and licking behaviors (phase 1, 0–10 min; phase 2, 10–60 min). Naloxone was injected 10 min before administration of SOG 100 µg to evaluate the involvement of SOG with an opioid receptor. Dose-responsiveness and ED50 values were calculated. RESULTS: Intrathecal SOG showed a significant reduction of the flinching responses at both phases in a dose-dependent manner. Significant effects were showed from the dose of 30 µg and maximum effects were achieved at a dose of 100 µg in both phases. The ED50 value (95% confidence intervals) of intrathecal SOG was 30.3 (25.8–35.5) µg during phase 1, and 48.0 (41.4–55.7) during phase 2. The antinociceptive effects of SOG (100 µg) were significantly reverted at both phases of the formalin test by naloxone. CONCLUSIONS: These results demonstrate that intrathecal SOG has a very strong antinociceptive effect in the formalin test and it seems the effect is related to an opioid receptor.
