BACKGROUND: This study was performed to evaluate our experience on laparoscopic appendectomy. METHODS: Retrospective analysis was performed on 2,856 patients who had been operated by laparoscopic appendectomy under diagnosis of acute appendicitis at the Sung-Ae Hospital and Kwang-Myoung Sung-Ae Hospital from October 1991 to July 1998. RESULTS: Among 2,856 patients who had undergone laparoscopic appendectomy,2,379 patients (83.3%) were operated due to simple acute appendicitis, 275 patients (9.6%) due to perforated appendicitis. Operation time was 44.6 minutes for simple acute appendicitis and 60.3 minutes for perforated appendicitis. In perforated appendicitis, intra-peritoneal irrigation and drain insertion was performed. The length of hospital stay in patient with simple acute appendicitis was 3.7 days (5.82 days in conventional appendectomy) and patients with perfotrated appendicitis was 6.1 days (9.91 days in conventional appen-dectomy). Complications such as wound infection, intra-abdomen abscess, trocar site bleeding, subcutaneous emphysema developed in 43 (1.5%) patients (79/1,947, 4.5% in conventional appendectomy). In 202 (7.1%) patients, appendix was normal, but another diseases were detected, including acute pelvic inflammation, ovarian cyst, mesenteric lymphadenitis, enteritis, diverticulitis in order. CONCLUSION: Overall complication rate was lower in laparoscopic appendectomy compared with conventional appendectomy and the length of hospitalization of laparoscopic appendectomy was shorter. When the acute appendicitis is suspected, especially in the reproductive women, the laparoscopic approach would be better diagnostic and therapeutic value than conventional method. Therefore laparoscopic appendectomy would be replaced with conventional appendectomy.

PURPOSE: The purposes of this study were to explore the effects of family cohesion and subjective happiness on death anxiety of Korean elders and to identify other factors contributing to death anxiety. METHODS: The participants were 280 elders who lived in P metropolitan city. Data were collected between November 5, 2011 and January 12, 2012 using the Short Portable Mental Status Questionnaire (SPMSQ), Family Cohesion Evaluation Scale, Subjective Happiness Scale, and Fear of Death Scale (FODS). Data were analyzed using the SPSS/WIN 19.0 program. RESULTS: Family cohesion, marital status, religious activity, perceived health status, and subjective happiness were included in the factors affecting death anxiety of Korean elders. These variables explained 50.1% of death anxiety. CONCLUSION: The results of the study indicate that these variables should be considered in developing nursing intervention programs to decrease death anxiety and increase family cohesion and subjective happiness for life integration in Korean elders.

BACKGROUND/AIMS: Chronic hepatitis C virus (HCV) infection is often associated with extrahepatic autoimmune disease, and autoantibodies such as anti-nuclear antibody (ANA) or anti-smooth muscle antibody (ASA). The presence of autoantibodies may make discrimination between chronic hepatitis C with autoimmune features and type 1 autoimmune hepatitis difficult. We studied the prevalence of autoantibodies in patients with chronic HCV infection and their clinical significance. MATERIALS AND METHODS: ANA, ASA, anti-mitochondrial antibody (AMA), anti-microsomal antibody (AmA), rheumatoid factor (RF), anti-cardiolipin antibody (aCL) and lupus anti-coagulant (LA) were tested in 116 patients (80 chronic hepatitis C, 36 liver cirrhosis). Genotypes of HCV were determined in 25 patients by INNO LiPA. RESULTS: The overall prevalence of autoantibody was 65.5%. The most common autoantibody was aCL (34.5%), followed by ANA (25%), RF (18%), LA (15.5%), ASA (6.9%), anti-microsomal antibody (6%) and AMA (1%). The positive rate of either ANA or ASA was 30.2%, but both were positive in 1.7% only. There was no difference in the demographic features, biochemistry, HCV genotypes and disease status between autoantibody-positive and autoantibody-negative patients. CONCLUSIONS: Autoantibodies were commonly found in patients with chronic HCV infection. But, the presence of autoantibodies may be a non-specific finding in chronic hepatitis C infection without clinical significance.

With modification of the acid etch technique and improvements of the physical and mechanical properties of the acrylic reain, the removal of directly bonded attachments and the finishing of the underlying enamel have become an acute clinical problem. This study was to evaluation the efficacy of recently introduced instrumentation and techniques to remove bonded brackets and residual resin, and restore the affected enamel surface to an acceptable clinical condition. Fortyeight premolar which were scheduled for extractio for orthodontic purposes were bonded with brackets usion super-C oftho. Four additional premolars with untreated surfaces were used as controls. After one weak the grackets were removed and the residual resin removed by hand scaler, green stone, green rubber wheel, sandpaper disc, tungsten carbide bur, Sof-lex disc. Half the experimental teeth were given a final pumicing and then all were extracted and stored in 50 percent ethanol. The scanning electron microscopy was used to evalusted the enamel surface. Following results were obtained; 1. A satisfactory result was obtained by means of the Sof-lex disc. 2. The order of the scratch formation was the procedure using hand scaler, green stone, tungsten carbide bur, sandpaper disc, green rubber wheel, and Sof-lex disc. 3. The procedures using green stone and tungsten carbide bur showed many groove formations and the other procedures showed none. 4. Final pumicing serves effectively to remove residual adhesive and restore the enamel surface.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) is a major problem associated with liver cirrhosis which has high mortality. Increased production of inflammatory mediators, such as tumor necrosis factor-a (TNF-a) and interleukin- (IL-) may be associated with development of renal impairment, one of the most important prognostic parameters in SBP. The aim of this study is to investigate the changes of these cytokines in ascitic fluid and plasma in patients with SBP and the relationship between these cytokines and development of renal impairment. METHODS: Forty patients with liver cirrhosis and ascites were studied 21 with SBP and 19 with sterile ascites. TNF-a and IL- levels in ascitic fluid and plasma were determined by ELISA at the time of diagnosis in both groups and 48 hours after antibiotics treatment in SBP patients. RESULTS: TNF-and IL- levels in ascitic fluid and plasma were significantly higher in patients with SBP than those without SBP (ascitic fluid TNF-a: 2.5+/-0.5 vs. 1.6+/-0.2; plasma TNF-a: 2.3+/-0.5 vs. 1.5+/-0.2; ascitic fluid IL-: 3.8+/-0.5 vs. 3.0+/-0.4; plasma IL-: 3.4+/-0.5 vs. 2.3+/-0.3, log pg/mL)(p<0.001). In patients with SBP, levels of TNF-a and IL- in ascitic fluid and plasma decreased 48 hours after antibiotics treatment. Eleven patients with SBP (11/21, 52%) developed renal impairment. Patients with renal impairment had significantly higher ascitic fluid and plasma TNF-a levels than those without renal impairment (median 2.5 vs. 2.1 for ascitic fluid, p=0.006; median 2.4 vs. 2.0, log pg/mL for plasma, p=0.04). Although four out of eleven (36%) patients who developed renal impairment died during hospitalization, all the patients without renal impairment survived (p=0.09). CONCLUSION: Our results suggest that the levels of TNF-a and IL- in ascitic fluid and plasma are increased in SBP and elevated levels of TNF-a in ascitic fluid and plasma may be associated with development of renal impairment, thus indicating poor prognosis in patients with SBP.

OBJECTIVE: To investigate the expression of apoptosis related proteins and apoptotic cells on the human ovarian follicles. MATERIALS AND METHODS: Thirty five Formalin-fixed paraffin-embedded human ovarian tissue blocks were selected from the surgical pathology files of the department of pathology, College of Medicine, Yonsei University, for the period from 1996 to 1998. All specimen were from premenopausal women aged from 32~45. Ovarian tissues were collected from the patients performing hysterectomy for benign uterine diseases. Immunohistochemical staining was performed for the detection of DNA fragmented cell, Bcl-2, Bax, Fas and Fas-ligand. RESULTS: Bcl-2 and bax were not expressed on the surrounding cells and oocyte of the primary, primordial and preantral follicles. Fas and Fas-ligand (Fas-L) were not expressed on the surrounding cells on the primordial and primary follicles. But expressed on the surrounding granulosa cells and oocyte in the primordial and primary follicles. In the healthy follicles, Bcl-2 was expressed on the granulosa cells, however, Bax was not expressed. DNA fragmented cells were expressed on the inner granulosa cell layer of atretic follicles. CONCLUSION: Fas, Fas-ligand, and Bax may be responsible for the follicular atresia and Bcl-2 may be involved in the follicular survival in the human ovary.

STUDY DESIGN: A retrospective study to evaluate the results of posterior lumbar interbody fusion (PLIF) using titanium cages filled with morselized local bone. OBJECTIVE: To verify the clinical and radiological results of the PLIF procedure using rectangular titanium cages filled with morselized local bone. SUMMARY AND LITERATURE REVIEW: Stabilization of the spine can be achieved by interbody arthrodesis through the posterior approach. However many significant problems including bone graft collapse, resorption, nonunion, and iliac donor site morbidity caused by the classic PLIF procedure need to be solved. The use of local bone and a titanium cage might be a solution. MATERIALS AND METHOD: Fifty-nine patients(average age at surgery, 51.3 years), who underwent surgery for degenerated low back disease, were enrolled in this study. The average follow-up duration was 19.9 months. The radiological fusion status, intervertebral disc heights, visual analogue scales, clinical outcomes were evaluated. RESULTS: Forty-three (73%) patients were classified as complete-union, 16 (27%) patients as probable-union, and no patients were classified as non-union. The average intervertebral disc height increased by 3.7 mm at immediate postoperatively, and the average subsidence was 1.1 mm at the final follow-up. The average visual analogue scale decreased from 5.5 to 1.4 for back pain and from 6.6 to 0.8 for radicular pain. Nineteen (32%) and 28 (48%) patients were classified as excellent and good, respectively, according to clinical outcome assessment by Kim and Kim criteria. The complications encountered were a dural tear in 8 patients, partial root injury in 1, and upper adjacent segment instability during follow-up in 2. CONCLUSION: PLIF using titanium cages filled with morselized local bone has the advantages of maintaining an intervertebral disc height, immediate stability, and the avoidance of donor site morbidity. However, longer-term results are needed, because the follow-up period of this study was relatively short

A 59-year-old man was admitted because of progressive proximal muscle weakness over 4 months. Serum creatine kinase was markedly increased and electromyography revealed myopathic pattern. Muscle biopsy showed nonspecific myopathic changes. No inflammatory change was shown. Thyroid function tests revealed very low thyroxine and low triiodo-L-thyronine, whereas thyroid-stimulating hormone was greatly increased as well as serum anti-thyroglobulin and microsome antibodies. The patient had hypothyroid myopathy due to Hashimoto's thyroiditis, which improved with L-thyroxine replacement.
