Phacofragmentation is one of the method of extracapsular lens extraction using ultrasonic frequency. We have used this method, sometimes inconjunction with anterior vitrectomy since April, 1980 for 10 eyes of 10 cataract or early adult cataract. Our machines for this purpose is one of the Girard type phacofragmetor, Berkeley Model 820 Fragmatome(TM), in conjunction with Berkeley Model 800A Ocutome(R). We have had quite good results after operation and we are sure this method was preferable operation at least in above mentioned cases. This is an our preliminary report and it will be necessary to perform operation to many cataract patients and to determine longterm effects of the operation.

We performed 15 cases of modified Bristow procedures for recurrent anterior instability of shoulder from january, 1987 to december, 1992 and the following results were obtained. 1. The patient's age at initial dislocation varied from 15 years to 29 years of age. 2. The most common cause of the recurrent anterior instability of shoulder was sport injury(6 cases) and next were traffic accident, hanging with one hand. 3. The average loss of external rotation of shoulder after operation were 10 degrees and internal rotation were 7 degrees. 4. The post-operative complication and recurrence were not observed. 5. End results were excellent in 7 and good in 5 by Rowe's grading system. 6. Strict attention to bone block placement was mandatory and decreased the risk of screw malpo-sition.

BACKGROUND: This study was conducted to investigate the roles of the spinal and peripheral gamma-aminobutyric acid (GABA)-ergic systems for the mechanical hypersensitivity produced by chronic compression of the dorsal root ganglion (CCD). METHODS: CCD was performed at the left 5th lumbar dorsal root ganglion. The paw withdrawal threshold (PWT) to von Frey stimuli was measured. The mechanical responsiveness of the lumbar dorsal horn neurons was examined. GABAergic drugs were delivered with intrathecal (i.t.) or intraplantar (i.pl.) injection or by topical application onto the spinal cord. RESULTS: CCD produced mechanical hypersensitivity, which was evidenced by the decrease of the PWT, and it lasting for 10 weeks. For the rats showing mechanical hypersensitivity, the mechanical responsiveness of the lumbar dorsal horn neurons was enhanced. A similar increase was observed with the normal lumbar dorsal horn neurons when the GABA-A receptor antagonist bicuculline was topically applied. An i.t. injection of GABA-A or GABA-B receptor agonist, muscimol or baclofen, alleviated the CCD-induced hypersensitivity. Topical application of same drugs attenuated the CCD-induced enhanced mechanical responsiveness of the lumbar dorsal horn neurons. CCD-induced hypersensitivity was also improved by low-dose muscimol applied (i.pl.) into the affected hind paw, whereas no effects could be observed with high-dose muscimol or baclofen. CONCLUSIONS: The results suggest that the neuropathic pain associated with compression of the dorsal root ganglion is caused by hyperexcitability of the dorsal horn neurons due to a loss of spinal GABAergic inhibition. Peripheral application of low-dose GABA-A receptor agonist can be useful to treat this pain.

Purpose: This study aimed to develop a Core Competency Scale for clinical nursing student educators. Methods: In this study, we constructed a conceptual framework, selected initial items, verified the content validity, conducted two rounds of Delphi expert consultation, selected secondary and tertiary items, and extracted the final items. The study included 242 clinical educators for nursing students. Item analysis, factor analysis, criterion validity, and internal consistency were used for the data analyses. Results: For the final scale, 35 items were selected and 5 factors were categorized, which together explain 61.7% of the total variance. The factors were education and evaluation, research and cooperation, ethical/legal principles, presenting leadership, and clinical practice. The scores for the scale significantly correlated with the teaching efficacy scale for clinical nursing instructors. The Cronbach’s alpha coefficient for the 35 items was .96. Conclusion The findings of this study demonstrated that the core competency scale has good validity and reliability. This scale can be used to assess the competency of clinical educators for nursing students; hence, it will help in evaluating the relationship between the skills of clinical educators for nursing students and the self-efficacy of those students.

IgA nephropathy is the most common form of glomerulonephritis characterized by deposit of IgA on mesangium. We experienced an elderly patient who was admitted for generalized edema, and diagnosed IgA nephropathy and early gastric cancer concomittantly. It has been reported that the incidence of nephrotic syndrome combined with malignancy increases with aging. Moreover, close relationship between IgA nephropathy and malignancy has been reported especially in the elderly patient. So, active investigations for possible malignancy are required in case of elderly patient with IgA nephropathy. In this case, we found improved proteinuria and hematuria of the patient after tumor resection during following up. This case suggest causal association between early gastric cancer and IgA nephropathy clinically.

BACKGROUND: In the last few decades, there has been a substantial increase in the population of aged people. Aging skin is a common concern for many people these days. OBJECTIVE: The purpose of this study was to evaluate the efficacy of cosmetics containing Ascidian tunic in reducing wrinkles. METHODS: Cream containing the Ascidian tunic was applied to right lateral epicanthal areas of 30 subjects for 8 weeks. As control group, a placebo which does not contain the Ascidian tunic was applied to the left lateral epicanthal areas of the subjects. Skin barrier function was evaluated and skin replicas were molded on both epicanthal areas every 4 weeks. The changes of the skin wrinkles were analyzed with skin visiometer. RESULTS: In comparison of the changes between groups treated with placebo and Ascidian tunic, there was statistically significant differences in hydration and sebum secretion. But there were no statistically significant differences in the result of R-value by visiometer. CONCLUSION: The treatment of Ascidian tunic extract seems to be partially effective in improving wrinkles, but further study is required.

Serum aspartate aminotransferase (AST) is a common enzyme for the evaluation of the hepatic, muscular and cardiac diseases and is produced also at kidney, brain, pancreas, lung, leukocytes, erythrocytes, etc. The elevation of its activity is usually caused by the necrosis of hepatocytes when there are not muscular injuries or myopathies. Recently, it is found that AST can exist as a macroenzyme by forming a complex with an immunoglobulin and this complex is erroneously considered to indicate the presence of liver disease as a result of elevation of AST activity on routine blood chemistry analysis. We experienced the patient with isolated AST elevation due to the formation of AST-mmunoglobulin complex confirmed by AST isoenzyme electrophoresis (EP).

PURPOSE: Pancreaticoduodenectomy (PD) is known to have high morbidity and mortality rates among the various abdominal operations, but there have been few reported current series of pancreaticoduodenectomy from large volume medical centers. The purpose of this study is to analyze the postoperative complications of PD and to assess the risk factors for postoperative morbidity. METHODS: A total of 398 cases of PD were performed by two surgeons from January 2003 to December 2007 at our institution and we retrospectively reviewed the medical records of these cases. RESULTS: 186 (46.7%) of 398 patients underwent pylorus preserving pancreaticoduodenectomy (PPPD) and 212 patients (53.3%) underwent a classic Whipple procedure. The most common indication for this procedure was pancreatic cancer (151 cases, 37.9%) and the second most common was intraductal papillary mucinous tumor (78 cases, 19.6%). The mean age was 57.2 years, ranging from 12 to 81. The mean postoperative hospital stay was 24.7 days. The most common complication was delayed gastric emptying (11.8%) and next was pancreatic fistula (10.3%), bleeding (6.5%) and new onset diabetes mellitus (DM) (4%). Four patients (1%) died of hospital mortality. The patients' age, gender, DM history, hypertension history and serum bilirubin level had no significant influences on the postoperative morbidity rate. CONCLUSIONS: Pancreaticoduodenectomy can be performed safely with an acceptable complication rate and minimal mortality if the surgeon has sufficient surgical experiences and with the advance in anesthesia and postoperative care.

Organ shortage is a serious problem in the field of solid organ transplantation. Increasing number of death on the waiting list, transplant tourism, black market for organ selling are all caused by organ shortage and these eventually causing poor quality of life for patient and family, and may give rise to a serious confusion in domestic transplant system. Since the KONOS launched in the year 2000, some portion of the illegal side of organ supply were corrected but the number of organ donor was hardly to increase. In order to search any solution for this problem, organ allocation study group under the Korean society for organ transplantation was actively worked from August 2008 through February 2009, and got some solution. Among them, amendment of the transplantation law including brain death committee, reporting system of suspected brain dead patients, and set up an independent organ procurement organization system for an effective organ procurement. Organ donation and increasing the number of donor is not a task only for transplant society, but is closely related with quality of life for peoples. This also can change the execution of budget of national medical health insurance. To give a correct understanding about this and activate the nationwide organ donation, the transplant society should have a key role with various medical and nursing society, hospital association, government, national assembly and every voluntary groups.

Only 0.15% of all donors in Korea are RhD negative, which has led to a chronic shortage of RhD negative blood. Most physicians are aware of the potential for RhD alloimmunization after transfusing RhD+ red blood cells into RhD- patients. Hence, the undertransfusion of RhD- patients might be occurring in Korea. A 66-year-old man without a history of transfusion tested negative for anti-D in his serum. In an emergency situation where RhD- blood was unavailable, the patient received two units of RhD+ RBCs. Anti-D was not detected over three months after the transfusion. The red cells of the patient showed no agglutination with the anti-D reagent and a negative result by the standard weak D test. The polymerase chain reaction-sequence specific primers (PCR-SSP) and sequencing revealed D(el) (1227G>A) in the patient.
