A ICL TM(STAAR Collamer Posterior chamber Implantable Contact Lens) lents ranging from -11D to -21.3D. And then we investigated the visualwas implanted in 12 eyes of 7 patients with preoperative spherical equivalents ranging from -11 D to -21.3 D. And then we investigated the visual acuity, mean endothelial cell loss, change of refractive error and postoperative complications.Average follow-up was 28.1 months. In the immediate postoperative days, all eyes had a significant increase in uncorrected visual acuity and the best corrected visual acuity was improved in 7 eyes(58.3%). Mean percent difference between preoperative and postoperative endothelial cell count was 3.22+/-0.05% . The mean preoperative spherical equivalent refraction was -15.65+/-2.78 D. At a mean follow-up of 1 month, mean spherical equivalent refraction was -1.67+/-0.72D, at a 6months, 12 months, 24 months, mean spherical equivalent refraction was each -1.56+/-0.72D, -1.63+/-0.68D, -1.73+/-0.76D. During follow-up days one eye developed an faint anterior subcapsular cataract but the patient remained symptom free. Other reported complication was transient increased intraocular pressure. Although the follow-up in our study was limited cases(12 eyes), from our experience, the posterior chamber implantable contact lens was efficacious and safe in the correction of high myopic refraction errors.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is highly prevalent in hospitals in Korea. The overall rate of MRSA in hospitals in Korea was estimated over 60%. Recently hospital infections caused by MRSA are getting increased and problematic in Korea, Our hospital Seoul Paik Hospital, has been trying to solve this problem. We had not applied exact methods for hospital infection control. Therefore, we adapted strict methods under the control of hospital infection control committee (HICC) and assessed the effectiveness of these methods. METHODS: Every month, the number of MRSA isolates was collected and analyzed; the results of the analysis were reported to every ward. All wards were supplied with Microshild(R) (Johnson & Johnson, Australia), Clean N' Fresh(R) (Carroll, USA), and standard paper towels. Health care workers were regularly educated for hospital infection control. The use of antibiotics was controlled by the HICC. We compared MRSA isolation rate between before and after applying the strict infection control methods under the regulation of HICC. Mann-Whitney U test, one-way ANOVA, and Chi-square test were used for statistical analysis of the results. RESULTS: After restricting the uses of antibiotics, glycopeptides and carbapenems were prescribed 15% less (20.3 vs 17.3 DDD /1000 patient-days) and 35% less (9.3 vs 6.0 DDD /1000 patient-days) respectively, compared to before restricting antibiotics. Methicillin resistance rate was decreased from 78% to 69% compared to before the methods(p=0.02). The isolation rate of MRSA was reduced by 31-42% from 2.33 to 1.35-1.60/1000 patient-days compared to before adapting strict infection control methods (p=0.04-0.07). CONCLUSION: This study showed that applying the strict infection control methods in the hospital can be effective to reduce the isolation rate of MRSA.

To evaluate the effect of capsular tension ring on prevention of capsular opening reduction induced by CCC in Phacoemulsification with silicone intraocular lens implantation, we prospectively studied 60 patients (60 eyes)who were operated from Sept, 1997 to Jun, 1998 at our hospital.All patients had standardized Phacoemulsification, continuous curvilinear capsulorhexis, and intraocular lens implantation performed by the same surgeon.Patients were randomized into two groups based on capsular tension ring insertion.We compared uncorrected visual acuity (UCVA), spherical equivalent (SE), astigmatism and the data obtained by the Anterior Eye Segment Analysis System (EAS-1000), anterior chamber depth, IOL tilting, decenteration, and anterior capsule opening area at 1 week and 1, 3, 6 months after surgery.Two groups showed a similar pattern of change of UCVA, SE and astigmatism. There are no statistical significances in comparison of anterior chamber depth and IOL decenteration in two groups, but IOL tilting of group II is greater than that of group I at 6 months after surgery.The mean anterior capsular opening area at 1, 3, 6 months postoperatively was smaller than that of 1 week in two groups, but no statistical significances were observed in group II (1, 3, 6 months, P = or > .05).The mean percentage reduction of group I was significantly smaller than that of group II at 3 and 6 months (P<.05)after surgery.Capsular tension ring might prevent a contraction of capsular opening and might enhance the stability of IOL.

To quantify the periodic changes in the area of anterior capsule opening after cataract surgery and to compare any difference between polymethylmethacrylate (PMMA), silicone and soft acrylic IOLs, we prospectively studied 442 patients (465 eyes)who were operated from September 1997 to November 1999 at our hospital.All patients had standardized phacoemulsification, continuous curvilinear capsulorhexis, and intraocular lens implantation performed by the same surgeon.Patients were randomized into three groups based on the type of intraocular lens.The area of anterior capsule opening was quantitated using the Anterior Eye Segment Analysis System (EAS-1000), and examinations were performed at 1 week and 1, 3 and 6 months after surgery.The mean anterior capsular opening area at 1, 3 and 6 months postoperatively was smaller than that of 1 week in all 3 groups (P<.05)and the mean percentage of reduction in the PMMA and soft acrylic intraocular lens groups was significantly smaller than that in the silicone intraocular lens group at 1, 3 and 6 months after surgery (P<.05).In the silicone group, the contraction of the anterior capsule opening was greater than either PMMA or soft acrylic intraocular lens groups.Further studies will be needed for the evaluation of clinical application of silicone and soft acrylic intraocular lens.

Because central venous O2 saturation (superior vena cava, ScvO2) can be monitored with less risk of the patients than mixed venous O2 saturation (pulmonary artery, SvO2), there have been studies to see if ScvO2 could replace SvO2. But previous studies showed that these two measurements were correlated but "not interchangeable. Therefore the authors compared right atrial C#b saturation (SraO2) with S vO2 over a wide range of cardiorespiratory status including control, hemorrhage, resuscitation, and hypoxia in anesthetized cats. We performed thoracotomy and inserted cannulae directly into the right atrium and the pulmonary artery. Blood sampling were obtained synchronously through the cannulae and tested immediately. The correlation coefficients in control, hemorrhage, resuscitation, and hypoxia groups were 0.876, 0.794, 0.946, 0.948 respectively and the two measurements in each group showed statistically significant correlations (p<0.05). But the biases of the two measurements in each group were 0.11+/-2.9, 0.35+/-4.2, -0.55+/-3.2, 0.23+/-4.2 respectively and the limits of agreement ( 2 standard deviation) in all groups exceeded permissible (5%) to conclude that the two measurements were in agreement. Thus, we reached the conclusion that the absolute values of SraO2, though not being sufficiently identical to S vO2 to calculate O2 uptake or pulmonary shunt precisely, can reflect the S vO2 trend following the O2 supply / demand change. Further clinical studies are needed.

Obstetrical procedures such as prolonged obstructed labour are responsible for the majority of vesicovaginal fistula(VVF) in developing countries, while gynecological procedures are more common causes in developed countries with hysterectomy accounting for 75% of fistulae. Other less common causes of VVF include uterine cancer, pelvic irradiation, gastrointestinal pelvic surgery, tuberculosis, intra-uterine device or Bechet's disease. Although radiation techniques are being advanced, several recent studies have shown the incidence of VVF after pelvic radiation therapy for cervical cancer to range from 0.6~2%. We report, a case of 47-year-old female with VVF after pelvic radiation therapy, which was treated by neurovascular pudendal-thigh flap.

Ulnar tunnel syndrome (UTS) is a compressive neuropathy of the upper extremity that shows various clinical symptoms according to the anatomic region of the compression site. Numerous factors may cause UTS, and most publications are case reports describing various etiologies; thus, obtaining a correct diagnosis is often challenging. Giant cell tumor of the tendon sheath (GCTTS) is well described to be a common benign soft tissue tumor of the hand; however, it is rarely reported to cause UTS. We report a case of GCTTS in Guyon's canal causing UTS that was misdiagnosed as handlebar palsy.

BACKGROUND: Pontine infarction extending to the basal surface has been reported to possess different characteristics from deep pontine infarction without extending to the basal surface. METHODS AND RESULTS: We studied 54 patients ; 30 patients with pontine infarction extending to the basal surface (group SE) and 24 patients with deep pontine infarction without extension (group DL) based on the site of the infarcts on precontrast sagittal T2WI. We assessed angiographic findings(MRA, 54; DSA, 31), risk factors, clinical features and the effectiveness of the intraluminal signal changes on spin-echo MRI in the diagnosis of occlusion or stenosis of the basilar artery. The incidence of basilar artery stenosis or occlusion in MRA or DSA in group SE(60%) was significantly more frequent than group DL(12.5%), whereas the incidence of vertebral artery stenosis or occlusion was not different between two groups. A noteworthy finding was that five patients (17%) of the group SE had not been extended to the basal surface on axial T2WI. The risk factors were similarly distributed between the two groups. The effectiveness of abnormal signal void of axial MRI was poor in the diagnosis of basilar artery occlusion or stenosis. CONCLUSIONS: Our results suggest that the two types of pontine infarction may be caused by different arterial pathology. Although the presence of abnormal flow void on MRI cannot predict the stenosis or occlusion of basilar artery, sagittal T2WI and angiographic study help to evaluate the patients with pontine infarction.
