Background & Objective: The number of ischemic stroke is increasing steadily. The recent stroke prevention strategies have targeted risk factors for preventing ischemic stroke. Community-based data that quantify the prevalence of these risk factors are needed to develop effective stroke prevention strategies. This study was performed aiming to establish customized prevention strategies by investigating vascular risk factors of ischemic stroke among the healthy adults in an urban population in Korea. Methods: The Prevention of Stroke and Dementia (PRESENT) survey collected data associated with stroke risk factors between 2007 and 2009 in Ansan city, Korea. Of 46,537 people, 2,843 were selected by random sampling, and final population included 358 men and 422 women over 50 years old. We checked modifiable risk factors, such as hypertension, diabetes mellitus, smoking, hyperlipidemia, atrial fibrillation, cardiovascular disease, obesity, and physical inactivity. Results: The mean age of study subjects was 60.1±8.2 years; 55.5% had hypertension, 18.6% had diabetes mellitus, 17.7% were current smoker, 44.9% had hyperlipidemia, 1.7% had atrial fibrillation, and 4.5% had cardiovascular disease. Men had more risk factors for stroke, and higher rates of diabetes mellitus and current smoking. However, women had higher cholesterol and obesity rates and lower physical activity. The proportion of individuals with >1 risk factor for stroke increased with age. Hypertension, diabetes mellitus, and cardiovascular diseases also increased with age, but low-density lipoprotein levels and current smoking decreased. Conclusions: This study provides valuable information to develop customized strategic policies for primary and secondary stroke prevention.

PURPOSE: To access the effect of phacoemulsification, using Neosonix(R) (Alcon Laboratories, TX, USA), on the cornea and lens opacity. METHODS: This study involved 42 eyes of 37 patients who underwent phacoemulsification using the Neosonix from December 2005 through March 2006. We measured the density and the thickness of lenses using a Scheimpflug camera and evaluated the correlation between the density and the phaco time. To evaluate the effects of Neosonix(R) on the corneal endothelium, we measured various corneal endothelial cell parameters, including corneal endothelial cell density, corneal thickness, and morphologic changes up to two months postoperatively. RESULTS: The preoperative mean values of lens density for the anterior cortex, nucleus, and posterior cortex were 105.86+/-34.99 CCT, 82.17+/-35.14 CCT, and 77.88+/-52.98 CCT, respectively. The mean phacoemulsification time was 48.67+/-29.79 seconds and increased significantly, according to the increase of the densities of the lens nucleus and cortex (p<0.01). Postoperative mean corneal endothelial cell density was 2741+/-474 cell/mm2 at one day, 2757+/-447 cell/mm2 at one month, and 2765+/-422 cell/mm2 at two months. Corneal endothelial cell loss was 4.39%, 3.83%, and 3.56% at one day, one month, and two months postoperatively, respectively. There was no statistically significant difference between the preoperative and postoperative values of corneal endothelial cell density (p>0.05). CONCLUSIONS: The phacoemulsification time using oscillation device significantly increased as the density of the lens cortex and nucleus increased, and there was no statistically significant difference between the preoperative and postoperative values of corneal endothelial cell density.

PURPOSE: To evaluate the effect of acupuncture on regional cerebral blood flow (rCBF) at acupoints suggested by oriental medicine to be related to the treatment of cerebrovascular diseases. MATERIALS AND METHODS: Rest/acupuncture-stimulation Tc-99m ECD brain SPECT using a same-dose subtraction method was performed on 54 normal volunteers (34 males, 20 females, age range from 18 to 62 years) using six paradigms: acupuncture at acupoints GV. 20, GV. 26, LI. 4, ST. 36 and SP. 6. In the control study, needle location was chosen on a non-meridian focus 1 cm posterior to the right fibular head. All images were spatially normalized, and the differences between rest and acupuncture stimulation were statistically analyzed using SPM for Windows . RESULTS: Acupuncture applied at acupoint GV. 20 increased rCBF in both the anterior frontal lobes, the right frontotemporal lobes, and the left anterior temporal lobe and the left cerebellar hemisphere. Acupuncture at GV. 26 increased rCBF in the left prefrontal cortex. Acupuncture at LI. 4 increased rCBF in the left prefrontal and both the inferior frontal lobes, and the left anterior temporal lobe and the left cerebellar hemisphere. Acupuncture at ST. 36 increased rCBF in the left anterior temporal lobe, the right inferior frontal lobes, and the left cerebellum. Acupuncture at SP. 6 increased rCBF in the left inferior frontal and anterior temporal lobes. In the control stimulation, no significant rCBF increase was observed. CONCLUSION: The results demonstrated a correlation between stimulation at each acupoint with increase in rCBF to the corresponding brain areas.

To elucidate whether dismembered pyeloplasty improves renal function, the authors studied 37 patients with ureteropelvic junction obstruction. Changes in various renal parameters pre-and postoperatively by 99mTc-DTPA diuretic renal scintigraphy(DTPA scan) and intravenous urography were evaluated. Subjects included 24 pediatric(mean age 9.7 years) and 13 adult(mean age 33 years) patients. Postoperative split renal function was improved in 79 % (l9/24) of pediatric patients and in 69%(9/13) of adult ones. While, the excretory slope was improved in 71%(17/24) of pediatric patients and in 77%( 10/13) of adult ones. Hydronephrosis on intravenous urogram was improved in 58% (14/24) and 54% (7/13), respectively between pediatric and adult patients. There was no statistically significant differences of improvement in split renal function and renographic washout curve between pediatric and adult patients. In summary, renal function was improved by dismembered pyeloplasty in both pediatric and adult patients.

PURPOSE: We wanted to analyze the causes of fixation failure after performing compression hip screw fixation for intertrochanteric fracture and we wanted to evaluate the methods to mange this type of failure. MATERIALS AND METHODS: From January 1999 to August 2005, 15 patients who underwent operation due to fixation failure after compression hip screw fixation for intertrochanteric fracture were evaluated, with at least 1 year follow up, for the fracture type, the status of the reduction, the aspects of failure, the causes of the failure and the clinical and radiologic results after operation. RESULTS: There were 7 cases of cut out by the hip screw, 1 case of hip screw breakage, 1 case of dislodging the hip screw, 2 cases of excessive sliding of the hip screw, 2 cases of plate breakage and 2 cases of fixation loss of the plate. The failure of cases was due to incorrect choice of the implants, and that of 9 cases was due to technical error. The Harris Hip score was an average of 67.8 for 10 cases of failed arthroplasty at the last follow up and 88.4 for 4 cases of re-fixation with a 95 degree angled blade plate, and bone union was achieved at a minimum of 5 months. CONCLUSION: It is important to choose an adequate implant and a precise technique to achieve a successful result for fixation of unstable intertrochanteric fracture, and refixation with a 95 degree angled blade plate could be considered for the management of failed intertrochanteric fracture with arthroplasty.

PURPOSE: To report a case of retinal detachment surgery in a patient with oculocutaneous albinism. CASE SUMMARY: A 44-year-old man visited our clinic complaining of decreased visual acuity in his left eye. His best corrected visual acuity was hand movement in his left eye, and rhegmatogenous retinal detachment involving the macula at the superior temporal site was found. We performed pars plana vitrectomy and attempted to reattach the retina using endolaser photocoagulation; however, the laser burn was not made, and we failed to reattach the retina. At that point, we carried out cryopexy around the retinal tear, and injected silicone oil into the vitreous cavity. Ten months after surgery, his best corrected visual acuity was 0.06, and there was no recurrent retinal detachment or proliferative vitreoretinopathy. CONCLUSIONS: In patients with albinism with melanin deficiency, cryopexy is more useful than laser photocoagulation for retinal detachment surgery.
