OBJECTIVE: Acute appendicitis is one of the most urgent surgical problems. Several factors have been considered as predictors of perforation, but this study focused on the change in pain pattern. The degree of pain and progression of appendicitis were analyzed assuming that the pain intensity would increase until the perforation and the degree of pain would decrease immediately after the perforation occurred. METHODS: In this study, 385 out of 467 patients, who were diagnosed with appendicitis in a single institution and aged between 15 and 65 years, were reviewed retrospectively. The patients' pain scores and the diameters of appendices were analyzed along with the accompanying complications. Correlation analysis and a Student's t-test were performed. RESULTS: In patients with complicated appendicitis, the mean numerical rating scale (NRS) was slightly higher than that of simple appendicitis, but there was no significant difference in the absolute value. Only the size of the appendix showed meaningful differences according to the combined computed tomography findings. The NRS distribution or appendiceal size did not correlate with the time duration from symptom onset. CONCLUSION: The appendiceal size tended to increase with progressing appendicitis. No significant correlation was observed between the patient's pain level and complications. The time duration from symptom onset did not show a relationship with the progression of appendicitis.

PURPOSE: This study investigated bone mineral density and nutritional state according to consumption of milk in Korean postmenopausal women who drink coffee. METHODS: Using the 2008~2009 Korean National Health & Nutrition Examination Survey data, a total of 1,373 postmenopausal females aged 50 yrs and over were analyzed after excluding those with diseases related to bone health. According to coffee and/or milk consumption, subjects were divided into four groups: coffee only, both coffee & milk, milk only, and none of the above. All data were processed after application of weighted values and adjustment of age, body mass index, physical activity, drinking, and smoking using a general linear model. For analysis of nutrient intake and bone density, data were additionally adjusted by total energy and calcium intake. RESULTS: The coffee & milk group had more subjects younger than 65 yrs and higher education, urban residents, and higher income than any other group. The coffee only group showed somewhat similar characteristics as the none of the above group, which showed the highest percentage of subjects older than 65 and in a lower education and socio-economic state. Body weight, height, body mass index, and lean mass were the highest in coffee & milk group and lowest in the none of the above group. On the other hand, the milk only group showed the lowest values for body mass index and waist circumference, whereas percent body fat did not show any difference among the groups. The coffee and milk group showed the highest bone mineral density in the total femur and lumbar spine as well as the highest nutritional state and most food group intakes, followed by the milk only group, coffee only group, and none of the above group. In the assessment of osteoporosis based on T-score of bone mineral density, although not significant, the coffee and milk group and milk only group, which showed a better nutritional state, included more subjects with a normal bone density, whereas the none of the above group included more subjects with osteoporosis than any other group. CONCLUSION: Bone mineral density in postmenopausal women might not be affected by coffee drinking if their diets are accompanied by balanced food and nutrient intake including milk.

Myelofibrosis results from stimulation of bone marrow stromal fibroblasts by fibrogenic cytokines elaborated by neoplastic or reactive cells in the marrow. Chronic idiopathic myelofibrosis should be differentiated from secondary myelofibrosis resulting from bone marrow involvement of malignant lymphoma because these diseases have different therapeutic strategies. Myelofibrosis in systemic lupus erythematosus is an uncommon but well-recognized complication, and identifying an autoimmune myelofibrosis is important in diagnosing this benign cause of myelofibrosis. We report two cases of myelofibrosis presenting the clinical and radiologic findings that mimicked malignant lymphoma -a case of autoimmune myelofibrosis associated with systemic lupus erythematosus showing extensive lymphadenopathy and a case of chronic idiopathic myelofibrosis with focal intrasplenic extramedullary hematopoiesis- and discuss the importance of the clinical information and radiologic findings for the pathologic diagnosis of myelofibrosis.

OBJECTIVE: Bilateral C1 lateral mass and C2 pedicle screw fixation (C1LM-C2P) is an ideal technique for correcting atlantoaxial instability (AAI). However, the inevitable situation of vertebral artery injury or unfavorable bone structure may necessitate the use of unilateral C1LM-C2P. This study compares the fusion rates of the C1 lateral mass and C2 pedicle screw in the unilateral and bilateral methods. METHODS: Over five years, C1LM-C2P was performed in 25 patients with AAI in our institute. Preoperative studies including cervical X-ray, three-dimensional computed tomography (CT), CT angiogram, and magnetic resonance imaging were performed. To evaluate bony fusion, measurements of the atlanto-dental interval (ADI) and CT scans were performed in the preoperative period, immediate postoperative period, and postoperatively at 1, 3, 6, and 12 months. RESULTS: Unilateral C1LM-C2P was performed in 11 patients (44%). The need to perform unilateral C1LM-C2P was due to anomalous course of the vertebral artery in eight patients (73%) and severe degenerative arthritis in three patients (27%). The mean ADI in the bilateral group was 2.09 mm in the immediate postoperative period and 1.75 mm in 12-months postoperatively. The mean ADI in the unilateral group was 1.82 mm in the immediate postoperative period and 1.91 mm in 12-months postoperatively. Comparison of ADI measurements showed no significant differences in either group (p=0.893), and the fusion rate was 100% in both groups. CONCLUSION: Although bilateral C1LM-C2P is effective for AAI from a biomechanical perspective, unilateral screw fixation is a useful alternative in patients with anatomical variations.

OBJECTIVE: The aim of our study is to evaluate the effect of uterine artery embolization as primary treatment for symptomatic uterine fibroid METHODS: From December 1999 to December 2004, 25 patients underwent uterine artery embolization for the treatment of uterine fibroid. The patients were followed up at regular intervals (at 1st, 3rd, 6th month and annual) for 3 years. The mean duration of follow-up was about 41 month (range; 41+/-15). During follow-up period, consecutive uterine and fibroid volume, and symptoms were checked. RESULTS: The uterine volumes were significantly reduced by 27% (P=0.0238) after 3month. And the fibroid volumes were significantly reduced by 59% (P=0.0070) after 1month. The uterine volumes were significantly reduced by 27% (P=0.0082) after 3 years. And the fibroid volumes were significantly reduced by 60% (P=0.0445) after 3 years. All women reported noticeable improvement of menorrhagia after complete of follow up. But, two of nine women who had symptoms of dysmenorrhea or lower abdominal pain, showed no changes in symptoms CONCLUSION: Uterine artery embolization appears to be effective in controlling symptoms, and substantially reducing uterine and fibroid volume with few complication after 3 years. However, long term follow-up will be necessary to establish the efficacy of this procedure.

PURPOSE: To compare the efficacy of intravitreal gatifloxacin with intravitreal vancomycin in the treatment of Staphylococcus epidermidis endophthalmitis in a rabbit model. METHODS: Albino rabbits (n=30), infected with an intravitreal inoculum of S. epidermidis (10(5) colony forming unit/0.1 mL), were divided into 6 groups (n=5). Groups I and IV received 200 microgram/0.1 mL of intravitreal gatifloxacin, and groups II and V were injected 1000 microgram/0.1 mL of vancomycin intravitreally. Intravitreal balanced salt solutions (untreated control) were given to Groups III and VI. Intravitreal antibiotic therapy commenced 24 hours after bacterial inoculation. The bactericidal efficacy was determined by electroretinography (ERG), clinical grading, bacterial culture of vitreous aspirates and histopathologic grading. ERGs and clinical gradings were performed only for groups I, II, and III and bacterial cultures were done only for groups IV, V, and VI. RESULTS: Eyes in the gatifloxacin groups showed similar appearance to those in the vancomycin treated groups clinically, histologically, and functionally as proved with ERG. All aspirates from the gatifloxacin and vancomycin groups were culture negative at 5 days after bacterial inoculation, whereas all eyes in the untreated control group were culture positive. CONCLUSIONS: This study demonstrated that intravitreal injection of 200 microgram /0.1mL gatifloxacin appeared to be equally effective compared to intravitreal 1000 microgram /0.1 mL vancomycin in the treatment of S. epidermidis endophthalmitis. If proven safe and efficacious after further study in humans, intravitreal injection of gatifloxacin could be considered an effective alternative to vancomycin for the treatment of S. epidermidis endophthalmitis.

Multiple gestation accounts for 1 percent of all pregnancies. But, the morbidity of congenital anomaly is more than 2 times in contrast to singleton gestation. The major congenital anomaly was developed about 2 percent in the multiple gestation. Hydrocephalus and anencephaly, known central nervous system anomaly, were seen about 0.1% each other in singleton gestation. We have experienced a case of prenatally detected concomitant hydrocephalus and anencephaly in twin pregnancy which was diagnosed by ultrasonography at 16 weeks gestation. Thus, we report a case with brief review of the literature.

The lipoma is the neoplasm of mesenchymal origin. Although most lipomas occur on the trunk and the proximal portion of the extremities, lipomas of the oral and maxillofacial regions are relatively rare, approximately 13% of all cases. Lipomas have been found in all age, but usually found between 40 and 60 years of age. Clinically the lipoma is a painless, slowly growing, nearly always benign soft mass. The treatment of choice is a surgical excision, and the recurrence is rare. But the infiltrating lipoma originated from muscle has high recurrence rate. It has ill-defined border and little or no evidence of encapsulation. Histologically there is a consistent infiltration with dissociation of the surrounding muscle fiber. The infiltrating lipoma should be excised with surrounding normal muscle and tissue to prevent the recurrence. This case was a 57-year-old female with a painless swelling of the right cervical and parotid areas which was diagnosed as large infiltrating lipoma by clinical examination and radiographic findings. The patient was treated by surgical excision and showed good functional and esthetic results. Histologically the tumor was diagnosed as infiltrating lipoma with no evidence of malignancy.

PURPOSE: Bronchopulmonary dysplasia (BPD) is characterized by arrested vascular and alveolar growth in the premature lung. Considering the consequences of arrested lung growth, the idea of administering bone marrow cells to enhance the inborn repair mechanism is promising as this may reduce the morbidity and mortality of BPD. We followed enhanced green fluorescent protein (EGFP)-labeled bone marrow cells (BMC) injected intraperitoneally into non-EGFP mice in order to determine their fate after transplantation. METHODS: An angiogenesis inhibitor, SU1498, was injected subcutaneously on day 3 in non-EGFP C57BL/6 newborn mice to create a model of arrested alveolar development. On the following day, 1x10(6) BMCs isolated from major histocompatibility complex (MHC)- matched syngenic EGFP mice were injected intraperitoneally to non-EGFP BPD mice. Morphometric analysis, immunostaining, and confocal microscopy were performed to determine the fate of EGFP-positive stem cells in the injured lung. RESULTS: SU1498 injection reduced alveolar surface area and mean alveolar volume in newborn mice. BMC injection resulted in recovery of lung structure comparable to controls. EGFP-positive BMCs were identified in the lungs of the recipient mice after intraperitoneal injection. The injected EGFP cells were co-stained with endothelial and epithelial cells of the developing lung as determined by confocal microscopy. CONCLUSION: Our results illustrated that EGFP-positive BMCs engrafted and trans- differentiated into epithelial and endothelial cells after intraperitoneal injection in a mouse model of arrested alveolar development.

This prospective study was performed to determine the effective antibiotics for use in treating acute appendicitis patients during the perioperative period. To identify the sensitive antibiotics, the peritoneal fluid was cultured during operation. Also, wound infection was defined as pus or serous discharge in the wound or when we opened the wound under suspicious of a wound problem. The results were obtained as follows: 1) A total of 138 cases treated during the two years from January 1995 to December 1996 were examined; 84 of them (60.87%) were found to have positive peritoneal fluid cultures, of which 29 (34.52%) were monomicrobial and 55 (65.48%) were polymicrobial. 2) The most common species were Escherichia coli (73.81%), Bacteroides (32.14%), Klebsiella (16.67%), Pseudomonas (9.52%), and Streptococcus (9.52%). 3) In the sensitivity test, the most sensitive drugs were aminoglycosides and cefotaxime. 4) Infectious complications, which developed in 27 (19.6%) patients, were wound infection and intraabdominal abscess. 5) The average length of stay for all patients 9.9 days (range: 3 to 32 days). 6) The common organisms curtured from the complication cases were E. coli and Bacteroides.
