To determine clinical features and outcomes of retinal detachments[RDs] following trans-scleral fixation of posterior chamber intraocular lens[PC-IOL], we reviewed the medical records of 249 eyes[239 patients] which had undergone trans-scleral fixation of PC-IOL and had been followed 6 months or longer. Retinal detachment occurred in 8 out of 249 eyes[3.2%]. The incidences of RDs were as follows:in 2/19 eyes[10.5%] with PC-IOL exchange for PC-IOL tilt, in 1/16 eyes[6.3%] with posterior capsule rupture during ECCE, in 1/26 eyes[3.8%] with ICCE, in 2/78 eyes[2.6%] with posterior capsule rupture during phacoemusification, in 2/106 eyes[1.9%] with aphakia, and in 0/4 eyes[0%] with anterior IOL exchange with PC-IOL. The sites of retinal break corresponded with the directions of needle during fixation in 5/8 eyes[62.5%] and all retinal breaks were located anterior to the equator. The timing of RD was between 2 weeks and 4.8 years after fixation although it occured within 2 months in most cases. Pars plana vitrectomy and scleral buckling were performed in 7 eyes and scleral buckling only in one eye. Retinal reattachment was achieved in seven eyes including three eyes which required two surgical interventions. The vitrectomy should be performed with meticulous care to reduce vitreous traction as much as possible during trans-scleral fixation of PC-IOL and a close follow-up examination for RD is required during the first two months.

We compared the rate of continuous curvilinear capsulorhexis[CCC]con traction and degree of postoperative capsular fibrosis between patients with non-proliferative diabetic retinopathy and age-matched non-diabetic patients after phacoemulsification with posterior chamber acryl foldable intraocular lens implantation.Sixty-two eyes of 42 patients of non-proliferative diabetic retinopathy and 78 eyes of 55 patients of control group who underwent cataract surgery with acryl foldable intraocular lens were enrolled in this retrospective study.During follow up examination the rate of CCC contractions were evaluated by NIDEK EAS-1000 System and we measured the area of anterior capsular opening.The diabetic patients average percentage of anterior capsular shirinkage rate was higher than non-diabetic patient's. But no statistically significant difference was found between the two groups. In conclusion, small incision cataract surgery with acryl foldable intraocular lens implantation showed good results in diabetic patients.Further studies will be needed for better clinical safety and efficacy.

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.

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.

PURPOSE: Adequate lymph node analysis is critical for appropriate staging in colorectal cancer. The aim of this study is to determine whether 12 or more nodes recovered in stage III rectal cancer results in improved oncologic outcomes. METHODS: Two hundred and forty-eight patients with stage III rectal cancer from 1995 through 2004 were reviewed. They were categorized into 2 subgroups by the number of nodes retrieved (<12 and > or =12), and oncologic outcomes in terms of 5-year overall and disease-free survival were analyzed for all patients, patients with American Joint Committee on Cancer (AJCC) N1 disease (N=145), and those with AJCC N2 (N=103). RESULTS: Five-year overall and disease-free survival was 79.0% and 58.4%, respectively. There was no significant difference in clincopathologic features between <12 retrieval group and > or =12 group. Although there was significant difference in overall survival and disease-free survival between the number (<12 and > or =12) of lymph nodes removed in N2 disease (P=0.043; P=0.022) in univariate analysis, the total number of lymph nodes retrieved was not a prognostic factor affecting survival in multivariate analysis. The N2 stage and lateral margin involvement were prognostic factors affecting survival in multivariate analysis. CONCLUSION: This study showed that the total number of lymph nodes analyzed for stage III rectal cancer is not a prognostic factor on overall or disease-free survival in multivariate analysis.

PURPOSE: This study was conducted to identify predictors of serious poisoning in patients with snake bite based on initial findings. METHODS: We conducted a retrospective study of patients with snake bite who were treated at the emergency department between January 2010 and December 2016. The patients were divided into two groups according to the severity of symptoms based on the traditional snakebite severity grading scale. The mild poisoning group (MP) was classified as those who had a grade I snakebite severity during the hospital stay, and the severe poisoning group (SP) was classified as patients who had grade I at the time of admission, but progressed to grade II-IV during hospitalization. Initial clinical manifestations and laboratory findings of the two groups were compared. RESULTS: Bite to hospital time intervals of SP were longer than those of MP (p=0.034), and the local effect score (LES) was higher in SP (p<0.001). Laboratory analyses revealed that creatine phosphokinase (p=0.044), creatine phosphokinase MB isoenzyme (CK-MB, p=0.011) and serum amylase (p=0.008) were significantly higher in SP. LES, CK-MB and serum amylase were significant prognostic predictors as indicated by univariate logistic regression analysis. Multivariate analysis revealed the following two significant predictors: LES (odds ratio=3.983, p<0.001) and serum amylase (odds ratio=1.020, p=0.017). CONCLUSION: In managing cases of snake bites, clinical manifestations and laboratory findings must be carefully evaluated. LES and serum amylase are predictive factors for severe poisoning, which is especially important to rapid determination of the intensive care of the patient.

Mature cystic teratoma of the ovary is the most common ovarian germ cell neoplasm representing 10-20% of all ovarian tumors. Malignant transformation rarely takes place, which is approximately 1-2% of all cases. The most common malignancy arising in mature cystic teratoma is squamous cell carcinoma. The prognosis of malignant transformation developing in mature cystic teratoma is poor and the management is not established due to the rarity of malignant degeneration. A case of stage Ia squamous cell carcinoma which developed in mature cystic teratoma of left ovary in a 43-year-old female is presented. The ovarian tumor was woman's fist-sized with intact capsule. Left oophorocystectomy was done. Above case with a brief review of literature is given.

BACKGROUND: Remifentanil sometimes elicits cough during induction of anesthesia, as with the use of other fentanyl congeners. We designed this study to investigate the incidence of remifentanil-induced cough (RIC) in children and to evaluate the effect of injection speed on RIC. METHODS: One hundred twenty ASA physical status I-II patients, aged 3-12 yr, undergoing general anesthesia were enrolled in the study. Patients were randomly assigned to one of the three groups. Patients in Group R30 received remifentanil 1.5 microg/kg at a constant rate over 30 s. Patients in Group R45 received remifentanil 1.5 microg/kg over 45 s, and patients in Group R60 received remifentanil 1.5 microg/kg over 60 s, respectively. Episodes of cough were recorded and graded as mild (1-2), moderate (3-4), or severe (5 or more). Mean arterial pressure (MAP), heart rate (HR), and SpO2 were recorded on arrival in the operating room (baseline) and 1 min after remifentanil infusion. RESULTS: The incidence of RIC was 33.3% in Group R30 (13 of 39 patients), 17.9% in Group R45 (7 of 39 patients), and 5.0% in Group R60 (2 of 40 patients). Patients in Group R60 had a significantly lower incidence of RIC than those in Group R30 (P = 0.001). The MAP, HR, and SpO2 values were not significantly different between groups. CONCLUSIONS: When intravenous remifentanil 1.5 microg/kg was administered in pediatric patients, the incidence of RIC decreased from 33 to 5% by increasing the injection time from 30 to 60 s. Remifentanil should be administered slowly over 60 s in children to suppress cough during anesthesia induction.
