BACKGROUND: As information technology evolves rapidly computer-based surveillance systems for nosocomial infection have been developed. Well designed computerized system could provide an opportunity for improving, enlarging, and conducting hospital-wide surveillance more efficiently in the situation with limited resources. Recently, we launched a new computerized monitoring system in a hospital where digital medical information system has been operated without paper chart. METHODS: We developed a new surveillance program based on the total Electronic Medical Record (EMR) system. Numerous critical medical information can be easily accessible through this system without further work. This includes major demographic data, essential information from the inpatient medical record, the laboratory information system, and the pharmacy information, Comprehensive Clinical Data Repository (CDR) system was also developed. CDR is potentially very useful to conduct a hospital-wide surveillance by integrating all the available information. RESULTS: This system consists of several programs in the EMR and the CDR environment. In the EMR system, inquiry for patients with fever, case ascertainment and registration of nosocomial infections, inquiry for patients with indwelling devices, microbiological reports, and data on antibiotic prescriptions were included. The CDR has integrated comprehensive inquiries for frequency of major pathogens in clinical isolates and their trends of antibiotic resistance, nosocomial infection rates based on the duration of the devices or hospitalization, and the history of antimicrobial usage based on defined daily dosage. Data obtained from the EMR and the CDR systems could be easily accessed by infectious diseases specialists and healthcare workers of infection control services at any place within the hospital. A new reporting system has been built up to facilitate identification of notifiable diseases among the list of diagnoses on the EMR. In addition, the "Alert" notice was designed to highlight isolation precautions for indicated cases. CONCLUSION: This new computerized surveillance program might be a valuable model to which other hospitals can refer to develop newer version of programs in the future.

Ankle sprain is one of the most common musculoskeletal injuries. Although most ankle sprains respond well to conservative measures, chronic instability following an acute sprain has been reported to occur in 20% to 40% of patients. Some individuals are eventually indicated for a lateral ankle ligament reconstruction due to persistent ankle instability. More than 80 surgical procedures have been described to address lateral ankle stability. These range from direct repair of the anterior talofibular ligament (ATFL) and of the calcaneofibular ligament (CFL) to reconstructions based on the use of autograft or allograft tissues. However, the best surgical option remains debatable. The modified Broström procedure is most widely used for direct ligament repair, but not always possible because of the poor ATFL or CFL quality or deficiency of these ligaments, which prevents effective shortening imbrication. Furthermore, the importance of a CFL reconstruction has been emphasized recently. On the other hand, it is difficult to achieve an efficient CFL reconstruction during the Broström procedure. Others have reported that an anatomic reconstruction of injured ligaments restores the normal resistance to anterior translation and inversion without restricting subtalar or ankle motion, and as a result, anatomic reconstructions for lateral ankle instability utilizing an autograft or allograft tendon have gained popularity.

PURPOSE: We reviewed the incidence, causes, location, treatment and prognosis of the severe iatrogenic ureteral avulsions caused by ureteroscopy procedures. MATERIALS AND METHODS: We analyzed the records of eight patients with ureteral avulsion out of 683 patients treated with ureteroscopic procedures, retrospectively. The patients had surgical correction or ureteral double-J stenting for the iatrogenic ureteral avulsions. RESULTS: The incidence of ureteral avulsion was 1.17%. While seven cases occurred during ureteroscopic removal of a stone, five cases among them occurred during stone basketing and two cases occurred during insertion of the ureteroscope. Another case among eight avulsion cases occurred while removing the during an endopyelotomy for a ureteral stricture. Depending on the length of the ureteral avulsion, four cases were over 2cm, the patientsopen surgical repair for ureteral continuity restoration immediately; three cases, under 2cm, were treated with indwelling ureteral double J stents, and one case with an injury to the entire ureter was treated with a nephrectomy. The result of the surgical treatment as the initial treatment was good in all cases. On the other hand, among the three cases with an inserted ureteral double-J stent, one case had aresult and the other two developed hydronephrosis. CONCLUSION: Careful attention to surgical techniques and awareness of risk factors and types of potential injuries are essential to reduce severe iatrogenic ureteral avulsions. Our reports suggest that open surgical repair is better than an indwelling ureteral double-J stent for patients with a ureteral avulsion.

OBJECTIVE: Hypertensive disorder in pregnancy is one of the most serious obstetrical complications. Apolipoprotein E (Apo E) genotype is polymorphic and recently it was reported to be associated with preeclampsia. We undertook this study to clarify whether polymorphic marker of apolipoprotein E is associated with the development of hypertensive disorder in pregnancy. METHODS: Retrospective chart review was done. DNA was extracted from maternal blood of 124 healthy pregnant women and 253 women with hypertensive diseases in pregnancy. Hypertensive disorders complicating pregnancy include gestational hypertension (n=44), preeclampsia (n=158; mild=56, severe=102), preeclampsia superimposed preeclampsia (n=30), and chronic hypertension (n=21). Apo E allele was amplified by polymerase chain reaction, size fractionated on 4% agarose gels, and stained with ethidium bromide. RESULTS: We found all six possible genotypes of Apo E. However, three genotypes, E2/2, E2/4 and E4/4, were uncommon in Korean. We analysed the data according to each allele. Allele frequencies of the Apo epsilon2, epsilon3 and epsilon4 were as follows: 6.8%, 83.0%, 10.2% in women with gestational hypertension, 4.5%, 84.8%, 10.7% in women with mild preeclampsia, 5.9%, 85.3%, 8.8% in women with severe preeclampsia, 1.7%, 91.7%, 6.7% in women with superimposed preeclampsia, 0.0%, 90.5%, 9.5% in women with chronic hypertension, and 5.2%, 86.5%, 8.5% in normal controls. No significant difference in Apo E alllele frequency was found among these groups (P>0.05). CONCLUSIONS: The study suggests that specific allele of apolipoprotein E does not appear to be a risk factor for hypertensive disorders complicating pregnancy in Korean population.

PURPOSE: To compare the accuracy of different power-calculation formulas in predicting the postoperative refraction of three-piece and one-piece intraocular lenses (IOL). METHODS: We retrospectively reviewed the medical records of 74 eyes (62 patients) that had undergone cataract surgery involving implantation of one of two IOLs―the SENSAR® AAB00 1-Piece Acrylic IOL (44 eyes), or the Hoya® VA60BB 3-Piece Acrylic IOL (30 eyes)―between October 2014 and March 2015. Axial length was measured using an optical low-coherence refractometry (Lenstar®), and biometry was then calculated by the pre-installed Lenstar program, which used the SRK/II, Sanders-Retzlaff-Kraff/Theoretical (SRK/T), and Hoffer Q formulas. Mean absolute error (MAE) and mean numeric error (MNE) were measured 1 day, 1 week, 1 month, and 2 months after surgery. RESULTS: Using the SRK/T and Hoffer Q formulas, the one-piece IOL group differed significantly from the three-piece IOL group in terms of the MNE obtained 1 month and 2 months after surgery. Across all formulas and time points, there were no significant differences between the groups in terms of MAE. CONCLUSIONS: There was no significant difference between the different power-calculation formulas. Starting 1 month after surgery, the three-piece IOL group showed myopic postoperative refraction compared to the predictive spherical equivalent using the SRK/T and Hoffer Q formulas.

BACKGROUND: Due to rapid economic growth and the development of medical science, the human life span is increasing nowadays. Due to this, old-aged people are increasing in number. However, the physiologic reserve power of old-aged people is lower than that of younger people. Therefore, it is necessary to be very careful about peri-operative care when doing surgery on old-aged people under general or spinal anesthesia. METHODS: We analyzed the medical records of 460 patients over 65 years of age who had undergone operations from August 1990 to July 1996 at the Department of General Surgery, Inchon Medical Center. RESULTS: (1) The ratio of geriatric surgical patients to all surgical patients during the same period was 14.7% (460/3122). Especially, the proportion of geriatric surgical patients increased to 17.0% during the last 2 years of this study compared to 16.2% for the previous 2 years, and 10.6% for the first 2 years. (2) The age distribution was 148 patients from 65 to 69 years (32.2%), 158 patients from 70 to 74 years (34.3%), 90 patients from 75 to 79 years (19.6%), and 64 patients over 80 years (13.9%). There was no significant difference between the number of men and women, there being 232 men and 228 women. (3) Among the 464 cases, 99 cases (21.3%) were malignant diseases compared to 365 cases (78.7%) of benign disease. Stomach cancer was the most common, 36 cases, colon cancer accounted for 31 cases and hepatobiliary cancer for 12 cases. Of the benign diseases, 103 cases (28.2%) were acute appendicitis, 85 (23.4%) were hepatobiliary diseases, 73 (20.1%) were hernias, and 35 (9.6%) were anal diseases. (4) Two hundred twenty-two (222) preoperative-associated diseases were found in 460 patients (48.3%). Cardiovascular disease was the most common (17.4%), and pulmonary disease was the 2nd most common (15.9%). (5) Of the total 133 cases of postoperative complication occurrence, wound infection was the most common, 43 cases, followed by pneumonia, 30 cases, respiratory failure, 11 cases, and renal failure, 7 cases. (6) The postoperative mortality rate was 5.0% and the most common cause was respiratory failure, 8 cases, followed by sepsis, 8 cases. CONCLUSION: The field of geriatric surgery must be pioneered and developed more by surgeons because the number of geriatric surgical patients is increasing more rapidly at present than in the past.
