1.A Survey on the Perceptions of Guardians of Pediatric Oculoplastic Patients.
Journal of the Korean Ophthalmological Society 2007;48(8):1023-1027
PURPOSE: This survey was performed to gather information about the guardians of pediatric oculoplastic patients undergoing certain medical care services in order to recommend improvements in these services. METHODS: Questionnaires were distributed to guardians of pediatric oculoplastic patients who were admitted for operations to correct epiblepharon and ptosis. Completed questionnaires, which numberd 100, were then analyzed. RESULTS: The results of this survey show that most guardians were the parents of the patient; most had a level of education higher than or equal to junior college graduation; and most were middle-class. The parents themselves had discovered their children's disease and had a great influence on the decision to operate. Most parents took an optimistic view of the results of the operation. The higher the guardians' economic status, the more likely he or she believed that both an ophthalmic and a plastic surgeon could perform oculoplastic operations. Many guardians chose an ophthalmic clinic over a plastic surgery clinic because the likelihood of a satisfactory result is higher and because these diseases are related to visual acuity. Half of the guardians knew that there is an oculoplastic clinic at the department of ophthalmology, and many of them gathered information about oculoplastic surgery from the internet. CONCLUSIONS: Better explanations about oculoplastic diseases and more education about these diseases should be available to the guardians of patients with these diseases. Systematic publicity for the field of oculoplastic surgery is needed urgently, and the availability of accurate information and specialized medical counseling about these diseases on the internet should be increased.

PURPOSE: To describe the clinical course of young patients with central retinal vein occlusion (CRVO). METHODS: We reviewed the records of patients 50 years or younger who presented with CRVO and who were followed up for at least 6 months. RESULTS: The average age of the patients was 37.7 years, and the mean follow-up time was 26.3 months. Participants included 27 patients with CRVO younger than 50 years among the total 393 patients with CRVO, and the sex distribution was nearly equal; 13 patients were male and 14 patients were female. Associated systemic diseases were hypertension (8 patients), diabetes (3 patients), stroke (3 patients), and myocardial infarction (1 patient). Of the 17 patients who had no systemic disease, 8 patients had hypercholesterolemia or another hematologic abnormalities. Of the 18 eyes with non-ischemic CRVO, 10 eyes (55.6%) showed improved final visual acuities (2 or more lines). Of the 9 eyes with ischemic CRVO, only 1 eye (11.1%) showed improved visual acuity. CONCLUSIONS: Hematological examination and treatment with systemic evaluation were recommended to younger patients with CRVO. The classification of retinal ischemia of young patients as well as that of older patients could be useful for the follow-up of patients and the assessment of its progression in the future.

Journal of the Korean Ophthalmological Society 2015;56(1):148-153
PURPOSE: We report a case of an acute incomitant esotropia with Wernike's encephalopathy. CASE SUMMARY: A 64-year-old male visited our hospital because of diplopia lasting a week. He was a chronic alcoholic drinking two bottles of makgeolli daily and eating little for a month. He showed -2 underaction of bilateral lateral rectus muscles and 45 prism diopters of esotropia at the primary position at the first visit. He had ataxia and mild cognitive impairment. There were high signal intensities in the periaqueductal area and mammillary bodies in the brain fluid attenuated inversion recovery magnetic resonance image. He was diagnosed with Wernike's encephalopathy clinically and was immediately treated with intravenous thiamine. He showed -0.5 underaction of bilateral lateral muscles and 8 prism diopters of esotropia at the primary position 3 days after thiamine treatment. CONCLUSIONS: Wernicke's encephalopathy is a medical emergency. If diagnosis and treatment are delayed, patients may have neurological sequelae that can lead to death. Esotropia and diplopia can be the presenting manifestations in Wernike's syndrome without other symptoms. In taking patient histories, physicians should ask about alcohol consumption and low food intake because of the possibility of acute incomitant esotropia associated with Wernicke's encephalopathy.

We report an unusual case of cerebral aneurysmal subarachnoid hemorrage (SAH) with Fabry's disease. A 42-year-old woman presented with aneurysmal SAH originated from a saccular aneurysm of the right posterior communicating artery. The patient was treated by an endovascular coil embolization of aneurysm. Postoperatively the patient recovered favorably without any neurological deficit. During her admission, the patient had a sign of proteinuria in urine analysis. The pathologic findings of kidney needle biopsy implied nephrosialidosis (mucolipidosis of lysosomal stroage disease), which is consistent with a Fabry's disease. It is uncommon that Fabry's disease is presented with aneurysmal SAH, especially in middle-aged patients, but could be a clinical concern. Further investigations are needed to reveal risk factors, vascular anatomy, and causative mechanisms of Fabry's disease with aneurysmal SAH.

OBJECTIVES: The optimal management of patients with spontaneous intracerebral hemorrhage (ICH) remains controversial. The aim of this study was to evaluate technical results and clinical outcomes of frameless stereotactic aspiration and fibrinolysis using urokinase performed in a single center. MATERIALS AND METHODS: The subjects of this study were 62 consecutive patients with spontaneous ICH who were treated with frameless stereotactic aspiration and subsequent fibrinolysis using urokinase between February 2009 and June 2010 in our hospital. The surgical results, procedure-related complications, and clinical outcomes were evaluated. RESULTS: A total of 62 patients were enrolled in the study. The median age was 54 years (range, 32-86). The mean initial Glasgow coma scale score was 7.7 (range 5-11). The mean initial hemorrhage volume was 43 cm3 (range 30-70). Seven patients (11.2%) died of respiratory failure (four patients), postoperative edema (two patients), and heart disease (one patient). There were seven cases of procedure-related complications (11.2%), including malpositioning of catheters (two patients), pneumocephalus (one patient), and rebleeding (four patients, 6.4%). At the three-month follow-up, a good outcome (three-month Glasgow outcome scale > 3) was noted in 32 patients (51.6%). CONCLUSIONS: Frameless stereotactic aspiration and subsequent fibrinolytic thearpy using urokinase for spontaneous ICH is a simple and safe procedure with low mortality and rebleeding rate.

OBJECTIVE: The objective of this study is to evaluate the clinical and angiographic outcomes after primary balloon angioplasty in patients with symptomatic middle cerebral artery (MCA, M1 segment) stenosis refractory to medical therapy. MATERIALS AND METHODS: Eleven patients with intracranial stenosis were treated with primary balloon angioplasty. All patients had MCA stenosis with recurrent transient ischemic attack (TIA). The indication for balloon angioplasty was patients with significant MCA stenosis: 1) age older than 18 years with recurrent or progressive TIA or infarction despite optimal medical therapy, including anti-coagulation, dual anti-platelet, and anti-lipid medication; 2) previous ischemic events or asymptomatic severe stenosis (more than 50%) with poor collateral cerebral circulation, or diminished cerebral perfusion on single photon emission computed tomography before and after administration of the intravenous dosage of acetazolamide. RESULTS: The median age of patients was 53 years (range 44-79). The technical success rate was 100%. Mean pretreatment stenosis degree was 83.63 +/- 9.53% and 29.1 +/- 15.4% before and after angioplasty, respectively. Procedural-related complications occurred in four of 11 patients (36%), but none of the patients had permanent neurological deficit. All patients were available for an average follow-up period of 19.4 +/- 5.1 months. One patient had a stroke in the territory of angioplasty at two months after angioplasty. The stroke free survival rate at 30 days and 12 months was 100% and 91%, respectively. Restenosis over 50% was observed in three of 11 patients (27%); all were asymptomatic. CONCLUSION: Intracranial angioplasty for symptomatic MCA stenosis refractory to medical therapy can be a treatment option to reduce the risk of further TIA or stroke.

PURPOSE: To compare visual acuity and intraocular straylight after implantation of clear and photochromic intraocular lenses (IOLs) in a mesopic lighting condition. METHODS: Clear IOLs were implanted in 95 eyes of 72 patients (clear IOL group), and photochromic IOLs were implanted in 22 eyes of 16 patients (photochromic IOL group). Best-corrected visual acuity (BCVA) was measured indoors before surgery and 1 month after surgery. Straylight values were measured indoors before surgery and 1 and 2 months after surgery using the C-quant straylight meter (Oculus GmbH, Wetzlar, Germany). RESULTS: There were no significant differences between the 2 groups in BCVA at 1 month postoperatively (p = 0.587). Mean straylight values of clear and photochromic IOL groups were 2.76 +/- 1.89 log (s) and 2.88 +/- 2.04 log (s) preoperatively, 1.39 +/- 0.84 log (s) and 1.32 +/- 0.26 log (s) at 1 month postoperatively, and 1.43 +/- 0.92 log (s) and 1.45 +/- 0.50 log (s) at 2 months postoperatively. There were no significant differences between the 2 groups in indoor straylight values (p = 0.778, 0.709, 0.929, before surgery, 1 and 2 months after surgery respectively). Repeated-measure analysis of straylight values also showed no significant difference between the 2 groups (p > 0.05). CONCLUSIONS: There were no significant differences in BCVA and straylight values between clear and photochromic IOL groups under a mesopic light condition. Therefore, photochromic IOL could be suitable choice for cataract patients who spend significant time under mesopic conditions.

8.Minimal Invasive Unilateral Transforaminal Lumbar Interbody Fusion by Sublaminar Decompression: Comparison to Bilateral Approach.
The Journal of the Korean Orthopaedic Association 2009;44(1):76-82
PURPOSE: This is a comparison of the unilateral and bilateral approaches for minimal invasive transforaminal lumbar interbody fusion (TLIF), and we did so by measuring the clinical and radiological results. MATERIALS AND METHODS: This study examined a consecutive series of 47 patients who underwent one-level TLIF (26 cases of the unilateral approach and 21 cases of the bilateral approach to the lumbar spine) and the follow-up data was compared with a minimum 1-year follow-up. Sublaminar decompression and contralateral foraminectomy were done in all the case of using the unilateral approach. The age of each patient, the amount of intraoperative blood loss, the postoperative drainage, the transfusion requirement and the surgery time were investigated. The clinical outcomes were analyzed using the visual analogue scale, the SF-36 Physical Composite Score (PCS) and the Oswestry disability index (ODI). The preoperative, postoperative & last follow-up changes in the height and angles of the disc in the fused segments and the lumbar lordotic angles were radiologically analyzed. RESULTS: There was no statistical difference between the two groups in terms of the clinical and radiographic results at the last follow-up. But the unilateral approach-group was found to have a less blood loss, less postoperative drainage, a lesser requirement for transfusion and a shorter surgery time. CONCLUSION: This study confirms that the unilateral approach can be the better way if the technical problems are solved.

BACKGROUND: Angiogenesis is an essential process for the growth and metastatic ability of solid tumors. One of the key factors known to be capable of stimulating tumor angiogenesis is the vascular endothelial growth factor (VEGF). The serum VEGF concentration has been shown to be a the malignant pleural effusion showing a correlation with the biochemical parameters. The VEGF has been shown to play a role in the inflammatory diseases, but rarely in the tuberculosis (TB). The serum and pleural fluid VEGF levels were measured in patients with lung cancer and TB. Their relationship with the clinical and laboratory parameters and repeated measurement 3 months after various anticancer treatments were evaluated to assess the utility of the VEGF as a tumor marker. METHODS: Using a sandwich enzyme-linked immunosorbent assay, the VEGF concentration was measured in both sera and pleural effusions collected from a total of 85 patients with lung cancer, 13 patients with TB and 20 healthy individuals. RESULTS: The serum VEGF levels in patients with lung cancer (619.9±722.8ph/ml) were significantly higher than those of healthy controls (215.9±191.1pg/ml), However, there was no significant difference between the VEGF levels in the lung cancer and TB patients. The serum VEGF levels were higher in large cell and undifferentiated carcinoma than in squamous cell carcinoma and adenocarcinoma. The serum VEGF levels of lung cancer patients revealed no significant relationship with the various clinical parameters. The VEGF concentrations in the malignant effusion (2,228.1±2,103.0pg/ml) were significantly higher than those in the TB effusion (897.6±978.8pg/ml). In the malignant pleural effusion, the VEGF levels revealed significant correlation with the number of red blood cells (r=0.75), the lactate dehydrogenase (LDH)(r=0.70), and glucose concentration (r=-0.55) in the pleural fluid. CONCLUSION: The serum VEGF levels were higher in the lung cancer patients. The VEGF levels were more elevated in the malignant pleural effusion than in the tuberculous effusion. In addition, the VEGF levels in the pleural fluid were several times higher than the matched serum values suggesting a local activation and possible etiologic role of VEGF in the formation of malignant effusions. The pleural VEGF levels showed a significant correlation with the numbers of red blood cells, LDH and glucose concentrations in the pleural fluid, which may represent the tumor burden.

PURPOSE: There are many cases of paroxysmal supraventricular tachycardia (PSVT) presenting to the emergency department (ED) with palpitation as the presenting symptom. Adenosine is usually administered for conversion to normal sinus rhythm, with a possible second dose in the case of no response. As adenosine has a short acting time, administration of the drug at a vessel as close to the heart as possible is recommended, followed by an extra normal saline bolus infusion. In this study, we hypothesized a better outcome when adenosine was administered after proper injection method instruction was given to the medical staff. METHODS: We retrospectively studied the population of PSVT patients treated with adenosine. The cases were divided into two groups: one group consisted of cases a year before instruction for adenosine use became routine practice, and the second was comprised of cases a year after instruction protocols had been put into place. We further analyzed the proportion of patients who converted to normal sinus rhythm after a single dose of adenosine. RESULTS: All 306 patients were included. Before instruction, 46 patients (40.0% of 115) converted to normal sinus rhythm after the first dose. After instruction, 108 patients (56.5% of 191) converted to normal sinus rhythm after the first dose, which was statistically significant (p<0.05). CONCLUSION: After receiving proper education, more patients converted to normal sinus rhythm after the first dose. Instruction for proper adenosine injection technique for PSVT cases can increase the success rate of rhythm conversion on the first attempt.
