Chronic kidney disease (CKD) is a common condition leading to renal dysfunction and is closely related to increased cardiovascular and mortality risk. CKD is an important public health issue, and recent genetic studies have verified common CKD susceptibility variants. This research examines the interrelationship between candidate genes polymorphisms of interferon lambda (IFNL) induction, its signaling pathway, and CKD. Methods: Seventy-five patients with advanced CKD and 312 healthy subjects (as controls) participated in this research. A replication set composed of 172 patients with advanced CKD and 365 controls was used for additional analysis. The genotype of single nucleotide polymorphisms (SNPs) was determined by the Axiom Genome-Wide Human Assay and SNaPshot assay. Results: The SNP of IFNL3 was significantly associated with CKD in the codominant (p = 0.02) and dominant models (p = 0.02). In addition, the SNPs of IFNL2 were significantly associated with CKD in the dominant model (p = 0.03), and the SNP of interferon alpha receptor 2 (IFNAR2) was significantly associated with CKD in the log-additive model (p = 0.03). Concerning rs148543092, in the IFNL3 gene, a significant association was observed after pooling the original and replication sets. Conclusion: These results indicate that SNPs in the IFNL induction and signal pathway may be associated with CKD risk in the Korean population. Finally, our results also show that the IFNL3 gene variant may be associated with CKD risk.

PURPOSE: To investigate the incidence rate of inferior oblique muscle overaction (IOOA) in the contralateral eye and the effect of inferior oblique (IO) muscle recession of the contralateral eye in the patients who received IO muscle recession for unilateral moderate (+2 or +3) primary IOOA. METHODS: Medical records of 88 patients with unilateral primary IOOA who underwent unilateral IO muscle recession were retrospectively reviewed and observed during a follow-up period of more than 1 year. Graded recession of the IO muscle was performed according to the degree of IOOA. If postoperative IOOA was below +1, the surgery was considered successful. If IOOA in the contralateral eye was more than +2 after surgery, the IOOA was considered to have occurred. RESULTS: In cases where IOOA was +2 and +3 before the surgery, the success rate was 98.2% and 100%, respectively, showing an overall success rate of 98.8%. The incidence of contralateral IOOA after recession of the unilateral IO muscle was 24.1% in the +2 group and 16.6% in the +3 group with an overall incidence rate of 21.6% and when the IO muscle recession of the contralateral eye was performed, the success rate was 100%. CONCLUSIONS: The incidence of contralateral IOOA was 21.6% after the unilateral IO muscle recession in moderate unilateral primary IOOA. A satisfactory outcome was obtained through an additional IO muscle recession in the contralateral eye.

PURPOSE: To evaluate the clinical results of arthroscopic inside-out repair leaving posterior horn tear. MATERIALS AND METHODS: Among the patients taken arthroscopic meniscal repair due to meniscus longitudinal tear from Jan. 1999 to Dec. 2004, total 32 patients were evaluated, and followed at minimum of two years(mean 32 months). Meniscal repair was done as maximum 3mm interval. The length of unrepaired posterior horn was mean 7.5mm. RESULTS: Preoperative Lysholm score was mean 62.5 and postoperative improved to 91.0. Twenty eight cases(87.5%) showed excellent or good results by Tapper and Hoover criteria. In 4 cases, symptoms recurred at 4 to 12 months after repair and 2 cases were combined with ACL deficiency. Second look arthroscopy was performed in 10 cases, 4 cases for recurred symptom and 6 cases for determining whether healing of untreated posterior horn occurred or not. We observed complete healing of 4 cases and incomplete healing of 2 cases on the acquisition of stability. CONCLUSION: It was suggested that meniscal repair leaving posterior horn tear may be healed if both stabilities of the torn area and the knee joint were maintained.

PURPOSE: We compare the effectiveness and safety of transurethral resection of the prostate(TURP) with those of open prostatectomy for large benign prostatic hyperplasia(BPH), that was over 70cc of prostate volume. MATERIALS AND METHODS: Seventy-one patients with a prostate volume of more than 70cc and who received TURP were classified to group A, while 41 patients who received open prostatectomy were classified to group B. The International Prostate Symptom Score(IPSS), maximal flow rate(Qmax) and post-voiding residual urine(PVR) volume were evaluated preoperatively and at 1, 3, 5 and over 5 years postoperatively. RESULTS: The postoperative IPSS, Qmax and PVR were significantly improved after 1 year(p<0.05). The IPSS and Qmax showed no significant differences between the two groups for 1, 3, 5 and over 5 years after operation(p>0.05). The PVR was significantly lower in group B at 1 year post-operation(p<0.05), but there were no significant difference between the groups for 3, 5 and over 5 years after operation(p>0.05). There were 7 cases(9.8%) of re-operation and 3 cases(4.2%) of re-medication after 5 years of operation. There were no major complications for each group. CONCLUSIONS: On comparison between TURP and open prostatectomy for the patients with large BPH, there were no significant difference in effectiveness and safety for 5 years. Even for the patients with BPH that showed a high volume, TURP is an effective operation that can replace open prostatectomy.

PURPOSE: Acute or chronic prostatic inflammation exists to varying degrees in surgical specimens of prostates, extirpated for the treatment of benign prostatic hyperplasia(BPH). We investigated the relationship between acute urinary retention(AUR) and intraprostatic inflammation. MATERIALS AND METHODS: Between January 1997 and December 2006, 221 patients underwent transurethral resection of the prostate(TURP) for the treatment of BPH. The patients were divided into 2 groups based on the indication for surgery; an AUR group and a lower urinary tract symptoms (LUTS) group. The area of acute inflammation, the extent, and the aggressiveness of chronic inflammation were classified into four grades. The grades of inflammation, prostate volume, age, serum prostate-specific antigen(PSA), and prior medical treatment were compared between the two groups. All specimens were reviewed by one pathologist. RESULTS: The AUR group consisted of 106(47.9%) patients, and the LUTS group consisted of 115(52.1%) patients. There were no statistical differences between the two groups with respect to the mean values of the age, prostate size, and severity of chronic inflammation. There was a significant relationship between AUR and the areas of acute inflammation, and the extent of chronic inflammation(p=0.014 and p=0.003, respectively). The aggressiveness of chronic inflammation had no relationship with AUR (p=0.062). The serum PSA level was higher in the AUR group than the LUTS group(11.5 vs. 5.3ng/ml, respectively). CONCLUSIONS: The association for AUR with acute and chronic inflammation was stronger than that which existed with prostate size. Thus intraprostatic inflammation is an important risk factor in AUR.

PURPOSE: The prognostic value of p53 remains controversial in transitional cell carcinomas of the bladder. Survivin, an inhibitor of apoptosis, is expressed in many human cancers. Recent studies have reported increased expression of survivin in superficial transitional cell carcinomas of the bladder. We investigated the expression of survivin and p53 and the clinical implications of this expression in superficial transitional cell carcinomas of the bladder. MATERIALS AND METHODS: Immunohistochemical staining of paraffin sections using a monoclonal antibody for survivin and p53 was performed in 82 cases of superficial transitional cell carcinomas of the bladder. Correlations between the expression of survivin and p53 and clinicopathological features, such as age, multiplicity of tumor, size, recurrence, and progression, were examined. RESULTS: Among 82 cases, positive survivin expression (greater than 20%) was observed in 59 cases. Positive p53 expression (greater than 20%) was observed in 46 cases. There were no significant differences in age, gender, multiplicity, tumor size, tumor grade, pT stage, recurrence, or progression-free survival between p53-positive and p53-negative groups (p>0.05). Also, there were no significant differences in age, gender, multiplicity, tumor size, tumor grade, or pT stage between survivin-positive and survivin-negative groups (p>0.05). However, recurrent-free and progression-free survivals were significantly lower in the survivin-positive group than in the survivin-negative group (p<0.05). CONCLUSIONS: The expression of survivin can be recommended as a useful marker for predicting disease recurrence and progression. Survivin may be superior to p53 as a prognostic factor in superficial transitional cell carcinoma of bladder.

The posterior capsular opacity is the most common complication occurring after extracapsular cataract extraction with posterior chamber intraocular lens implantation. For the purpose of the object analysis of the posterior capsular opacity, 127 eyes with the posterior capsular opacities were observed at 2 years after operation using the retroillumination and slit beam of Scheimpflug camera. In this study, the patients were undergone extracapsular cataract extraction with posterior chamber intraocular lens implantation at Inha university hospital from January 1997 to December 1997. Of 127 eyes, 89 eyes were free of diabetes mellitus, 38 eyes not. 89 eyes, free of diabetes mellitus, were 24 eyes whose posterior capsular thickness was thinner than 0.06 mm, 40 eyes from 0.06 mm to 0.12 mm, 17 eyes from 0.12 mm to 0.18 mm, and 8 eyes above 0.18 mm.Visual acuity of four groups had statistical difference with one another.There was significant correlation between the mean visual acuity and the thickness of center of the posterior capsule statistically.There was significant correlation between the mean visual acuity and the area of posterior capsular opacity, between the mean visual acuity and the inclusion of visual axis in the opaque area statistically.In conclusion, if we measure the thickness and area of posterior capsular opacity using Scheimpflug camera with regular interval, we will get the knowledge of progression of after cataract.

Minimally invasive cardiac surgery including robotic technique has become increasingly popular over the last decade. The advantages of such technique include improved cosmesis and healing, and reduced stress response, hospital and intensive care unit stay, and transfusion requirements. Robot-assisted cardiac surgery requires prolonged one-lung ventilation to optimize exposure. Remote-access perfusion requires appropriate positioning of multiple catheters to establish cardiopulmonary bypass. Carbon dioxide insufflation into the thorax can cause hemodynamic instability and carbon dioxide embolism. Limited exposure of the heart may pose difficulties with management of arrhythmia, hemostasis, myocardial protection and de-airing at the end of surgery. Limited access due to robot manipulator would make rapid intervention for cardiopulmonary resuscitation difficult or impossible. This case report describes robot-asssisted atrial septal defect repair and discusses the anesthetic issues associated with minimally invasive cardiac surgery including robotic cardiac surgery.
