1.The Relationship between the Nuclear Density Using Scheimpflug Imaging with Phacoemulsification Parameters.
Journal of the Korean Ophthalmological Society 2015;56(10):1552-1557
PURPOSE: To evaluate the correlation between nuclear density measured using the Pentacam(R) (Oculus Optikgerate GmbH, Wetzlar, Germany) Scheimpflug imaging system and phacoemulsification parameters. METHODS: The nuclear density was measured using maximal nuclear density with ImageJ, Pentacam(R) nucleus staging (PNS), average value and maximal value in lens densitometry. Intraoperatively, effective phaco time (EPT) and balanced salt solution (BSS) used were noted and compared with the nuclear density calculation methods. As an index of corneal endothelial cells, the changes in cell density (CD) were compared with the nuclear density. RESULTS: Regarding EPT, maximal nuclear density with ImageJ (r = 0.379, p < 0.01) and PNS (r = 0.367, p < 0.01) were correlated positively, but the other methods were not correlated. Concerning BSS used, maximal nuclear density with ImageJ (r = 0.279, p = 0.03) and PNS (r = 0.286, p = 0.04) were positively correlated, but the other methods were not correlated. The specular microscopy showed that as the nuclear density increased, the postoperative CD tended to decrease, but without statistical significance. CONCLUSIONS: Preoperative nuclear density measurements using maximal nuclear density with ImageJ or PNS were correlated with phacoemulsification parameters.

Severely worn dentition causes various complications such as loss of tooth structure, discoloration, pulp complications and loss of function and aesthetics. In this case, the patient showed particularly severe attrition in the anterior teeth and lack of space for restoration. The amount of vertical dimension was determined based on the diagnostic wax up, and the patient’s adaptation was evaluated by using a removable occlusal splint for 6 weeks. Thereafter, the coordination of the muscular nervous system, aesthetics, temporomandibular joint were re-evaluated for 3 months by restoring the fixed provisional restoration. Through the above treatment process, the final restoration was completed with full mouth fixed prosthesis using monolithic zirconia, and functionally and aesthetically stable results were obtained.

PURPOSE: Breast conserving surgery using mesh can effectively fill the defective space, but there is the risk of infection. METHODS: From June 2007 to August 2010, 243 patients who underwent breast conserving surgery with polyglactin 910 mesh insert for breast cancer at our institution were retrospectively studied. RESULTS: Infection occurred in 25 (10.3%) of 243 patients. When comparing the infection and non-infection groups in multivariate analysis, there was no significant difference in age, underlying disease, preoperative biopsy methods, mass location, axillary lymph node dissection, operative methods, neoadjuvant or adjuvant chemotherapy use, mass size and removed breast volume. The infection appeared more common only in patients with body mass index (BMI) greater than 25. Infection symptoms occurred, on average, 119.5 days after surgery, and the average duration of the required treatment was 34.4 days. Out of 25 patients with postoperative infection complications, 16 (64%) patients underwent incision and drainage with mesh removal, whereas the remaining 9 (36%) only required conservative treatment. CONCLUSION: During breast conserving surgery, the risk of infection is increased in patients with high BMI, and should be taken into account when considering insertion of a polyglactin 910 mesh. Patient's age, underlying disease and perioperative treatment methods were not significant risk factors for developing mesh infection. Given that most infections seem to develop symptoms one month after surgery, a long enough observation period should be initiated. Early detection and appropriate conservative treatments may effectively address infections, thus reducing the need for more invasive therapies.

In oriental medicine, classification of the Sasang constitutional types (Tae-Yang, Tae-Eum, So-Yang, and So-Eum) is important for the treatment. To classify the Sasang constitutional types, the old methods such as pulse palpation are not objective; the recent methods such as immunohematology are expensive, painful, and time consuming. To overcome this problem, a body measurement, one of the anthropological methods, has been developed. The purpose of this study was to define whether the fingerprint, other one of the anthropological methods, is helpful to classify the Sasang constitutional types. Thus, we looked for the interrelationship between the fingerprint and Sasang constitutional types. Before analyzing the fingerprint, two kinds of questionnaires for classifying the Sasang constitutional types were surveyed on 760 Koreans (465 males, 295 females). As there was no Tae-Yang individual, we only could find the fingerprint characteristics of Tae-Eum(288 persons), So-Yang (193 persons), and So-Eum(279 persons) individuals. In the fingerprints of Tae-Eum individual, the arch types were more frequent, and the loop types were less frequent. These characteristics were prominent in female, right, second, and fifth fingers. In those of So-Yang individual, the arch types were less frequent, and the whorl types were more frequent. These characteristics were prominent in male, female, left, first, second, third, and fifth fingers. In those of So-Yang individual, fingerprint ridge count was greater in fourth finger. In those of So-Eum individual, loop types were more frequent, and whorl types were less frequent. These characteristics were prominent in male, right, left, first, third, and fifth fingers. In those of So-Eum individual, fingerprint ridge count was lesser. These characteristics were prominent in male, fourth, and fifth fingers. The fingerprint seems to be helpful to classify the Sasang constitutional types.

PURPOSE: A choledochoscopy is useful for treating stone disease in the biliary tract. In the era of laparoscopic surgery, this method is expected to be used more widely. Its use during surgery may not only aid disease treatment, but may also help in making a differential diagnosis and a decision on the appropriate operative method. The aim of this study was to determine the role of intraoperative choledochoscopy in biliary surgery. METHODS: This study was a prospective analysis for 119 cases of biliary surgery where a choledochoscopy was used at the Ewha Womans University Mokdong Hospital from June, 1999 to February, 2001. An attempt was made to determine if the use of choledochoscopy altered the preoperative diagnosis, added another diagnosis and influenced the surgical treatment. In addition, the frequency of the remnant stones in biliary stone disease, and the complications related with this procedure were evaluated. RESULTS: The male to female ratio was 1:1.53, and the mean age was 61.1 (+/-14.53) years. A choledochoscopy was used in 82 cases (69%) in open surgery, and 37 cases (31%) in laparoscopic surgery. In 31 cases (26.1%), the diagnosis was changed by the choledochoscopic findings. In 9 cases (7.5%), new finding that was not recognized in the preoperative state was added with the use of choledochoscopy. The surgical method was influenced by the use of a choledochoscopy in 39 cases (32.8%). The remnant stones in patients with an intrahepatic duct stone and common bile duct stone were detected in 8 cases and 3 cases, respectively. The respective clearance rate of the stones were 79.5% (31/39) and 94.5% (52/55). There was no complications and side effects associated with the use of choledochoscopy. The mean time for diagnostic use was 14.6 (+/-10.0) minutes and for therapeutic use was 47 (+/-60.4) minutes. CONCLUSION: Intraoperative choledochoscopy provided useful information for a precise diagnosis and assisted in determining the appropriate treatment for biliary disease. Furthermore, it is very important for making a differential diagnosis in patients with an undetermined malignancy.

PURPOSE: To evaluate the safety of a laparoscopic cholecystectomy in acute, or complicated, cholecystitis in patients older than sixty. METHODS: A prospective study was performed, at the Ewha Womans University Mokdong Hospital, on a series of elderly patients (>60 years; n=137) who had undergone a laparoscopic cholecystectomy due to acute, or complicated, cholecystitis between March 1997 and December 2001. We divided the patients into 3 groups; ASA 1 (n=33, 24.1%), ASA 2 (n=79, 57.7%) and ASA 3 (n=25, 18.3%), according to their ASA (American Society of Anesthesiologist) classification. No patient was categorized as either ASA 4, 5 or 6. RESULTS: The mean age of the ASA 3 patients was 71.9+/-6.9 years, which was older than the 65.7+/-6.0 years of the ASA 1 patients (P<0.05). The preoperative hospital stay for the ASA 3 patients was 8.8+/-5.6 days, compared to 5.6+/-3.7 days for the ASA 1 patients (P<0.05). The incidences of complicated cholecystitis were lower in the ASA 1 (n=8, 24.2%) than in both the ASA 2 (n=40, 50.6%) and 3 patients (n=12, 66.7%) (P<0.05). The mean operating times for the ASA 2 and 3 patients were longer, at 111.0+/-58.2 and 114.0+/-62.7 minutes, retrospectively, than the 85.0+/-33.1 minutes for the ASA 1 patients (P<0.05). Drain insertions were more frequently performed in the ASA 2 (n=33, 44.4%) and 3 (n=15, 60.0%) than in the ASA 1 patients (n=10, 30.3%) (P<0.05). Postoperative morbidity was more frequent in the ASA 3 (n=5, 20.0%) than ASA 1 (n=3, 9.1%) patients. However, in terms of the postoperative recovery parameters (time to diet, hospital stay), there were no difference between the three groups (P>0.05). One death, due to acute myocardial infarction, occurred in one of the ASA 3 patients. CONCLUSION: A laparoscopic cholecystectomy in acute, or complicated, cholecystitis could be an option in elderly-high risk patients.

BACKGROUND AND OBJECTIVES: The repolarization abnormalities, after radiofrequency catheter ablation (RFCA) of accessory pathway (AP) in patients with Wolff-Parkinson-White (WPW) syndrome, is commonly appeared in standard 12 lead electrocardiogram (ECG) as inverted T waves. We analyzed the serial ECGs after RFCA of AP in patients with WPW syndrome, in order to understand the repolarization abnormalities after RFCA. MATERIALS AND METHOD: The study patients were consisted of ninety two patients (mean age: 35 years old, male: 56 patients) out of 157 patients whose ECGs were taken at before, immediately after, one day, one, four, eight, twelve week (s) after RFCA from December 1992 to July 1997. RESULTS: The seventy three patients (79%) out of ninety two patients showed the repolarization abnormalities and the thirteen patients (14%) showed normalization of secondary T wave changes immediately after RFCA. In contrast, six patients (7%) did not show any T wave changes after RFCA and they had left lateral AP. The lead that most frequently showed inverted T wave changes after RFCA was lateral lead (lead I, aVL) in case of left lateral AP and inferior lead (II, III, aVF) in case of other APs. The incidence of repolarization abnormalities after RFCA was significantly higher in patients whose preRFCA QRS duration is longer (> or =0.12 sec). The concordance rate of repolarization abnormalities after RFCA was 86% (63 patients of 73 patients showing repolarization abnormalities after RFCA). The normalization of repolarization abnormalities after RFCA was acquired in sixty four patients (94%) out of sixty eight patients who showed repolarization abnormalities and followed up to twelve weeks after RFCA. The mean time interval to the normalization of repolarization abnormalities after RFCA was 4.3+/-3.2 weeks. The time interval to the normalization of repolarization abnormality after RFCA was not related with age, AP or preRFCA QRS duration. CONCLUSION: The ECG lead, in which the repolarization abnormalities occurs after RFCA , is related with the location of the AP. The repolarization abnormalities after RFCA were more common in patients with longer preRFCA QRS duration. The repolarization abnormalities after RFCA could not be understood only by cardiac memory.

PURPOSE: The purpose of this study was to evaluate the feasibility and potential benefits of Hand-Assisted Laparoscopic Surgery (HALS) with the HandPort system. The surgeon inserts the nondominant hand into the abdomen while the pneumoperitoneum is maintained. The hand assists laparoscopic instruments and is helpful in complex laparoscopic surgery. This approach provides an excellent means to explore, to retract safely, and to apply immediate hemostasis when needed. METHODS: A prospective study was performed in patients who had undergone surgical intervention with the HandPort system at Ewha Womans University Mok-Dong Hospital. The surgeon was free to test the device in any situation where they expected a potential advantage over conventional laparoscopy. The surgeon inserted the nondominant hand into the abdomen while the pneumoperitoneum was generally maintained at 13 mmHg. RESULTS: Thirteen patients were entered in the study. Operations included radical gastrectomy in 8 cases, subtotal gastrectomy in 1 case, hemicolecotmy in 2, distal pancreatectomy with splenectomy in 1, nephrectomy with splenectomy in 1. The mean incision size for the HandPort device was 7.5 cm for the nondominant hand. None of the patients required conversion to open surgery as a result of an unmanageable air leak. There were no postoperative problems and no cases of mortality. CONCLUSION: HALS with the HandPort system is helpful in complex laparoscopic surgery and appeared to be useful in minimally invasive procedures considered too complex for,a laparoscopic approach.
