Tumors of umbilical cord, especially angiomyxoma, are extremely rare lesions. To our knowledge, five cases of angiomyxoma have been reported previously in the umbilical cord. Sonography two weeks after the finding of an elevated serum alpha-fetoprotein, detected a mass of the umbilical cord in a 27-year-old multiparous woman at 18(+3) weeks gestation. Previous sonogram was normal (11 weeks gestational age). At 26 weeks, a premature female infant was delivered by induction and a mass was located in the region of placental insertion of the cord. Section through the mass revealed rubbery myxoid appearance. Microcopically, numerous small vascular channels with thin walls were embedded in loose myxoid matrix. A case of angiomyxoma of umbilical cord with elevation of serum alpha-fetoprotein is presented together with a review of the literature. We hope that this case will help define the natural history of primary angiomyxoma of umbilical cord.

PURPOSE: Objective measurements of knee of flexor and extensor strength using isokinetic equipment and function after total knee arthroplasty (TKA) were evaluated until postoperative 12 months. MATERIALS AND METHODS: The control group constituted of 15 persons who were of same age and weight without knee problems. Most of the patients (70%) were operated on both knees simultaneously. The patient group consisted of constituted with 20 patients (34 cases). Isokinetic testing (Cybex) of knee flexor and extensor strength of knee and functional evaluation by HSS score was performed preoperatively and at 3, 6, 12 months postoperatively. RESULTS: The peak torque of the knee extensor and flexor muscle in the patient group was decreased by 17-41% compared to the control group. Especially, the peak torque of extensor was more decreased than flexor muscles. At postoperative 12 months, the peak-torque values of hamstring and quadriceps were able to attain the same strength levels of the preoperative knee. According to the grade of the Hospital for Special Surgery knee rating scales by Insall, 28 cases (82 %) in the patient group could obtain good result at postoperative one year. CONCLUSIONS: Exercises to increase the strength of extensor should be emphasized in the rehabilitation programs after TKA

PURPOSE: This exploratory study was done to categorize medical personnel's perceptions of burnout and analyzed the characteristics. METHODS: Q methodology was applied using a 45 Q-sample categorized on an 11-point scale which was completed by nurses and doctors working at a university hospital in Seoul, Korea. Collected data were analyzed using the PC-QUANL program. RESULTS: Medical personnel's perceptions of burnout were categorized into three types; 33.83% of the total variance was explained. The first type was 'functionally deteriorating pressure' the second type was 'daily powerlessness' and the third was 'achievement-oriented re-energization'. CONCLUSION: There is a need to establish and apply intervention strategies for each type to alleviate medical personnel burnout and increase work efficiency to qualitatively improve medical services.

PURPOSE: This study aimed at determining the detection rate of respiratory viruses and at investigating the risk factors associated with respiratory virus detection in young infants. METHODS: From September 2011 to August 2012, nasopharyngeal swabs were obtained from 227 infants aged < or =90 days with suspected infectious diseases, including sepsis. We performed a retrospective analysis of their clinical characteristics. The prevalence of respiratory viruses in their nasopharyngeal swabs was assayed by real-time polymerase chain reaction (real-time PCR). RESULTS: In total, 157 (69.2%) infants had more than one of the following respiratory viruses: respiratory syncytial virus (n=75), rhinovirus (n=42), influenza virus (n=18), parainfluenza virus (n=15), human metapneumovirus (n=9), coronavirus (n=9), adenovirus (n=4), and bocavirus (n=3). During the same period, bacterial infections were confirmed in 24 infants (10.6%). The detection of respiratory viruses was significantly associated with the presence of cough, a family history of respiratory illness, and a seasonal preference (fall/winter). Using logistic regression analysis, these 3 variables were also identified as significant risk factors. During fall and winter, detection of respiratory viruses was significantly higher in infants who did not have a bacterial infection. CONCLUSION: Respiratory virus is an important pathogen in young infants admitted to a hospital, who are suspected with infectious diseases. Detection of respiratory viruses in young infants was associated with seasonality (fall/winter), presence of respiratory symptoms and a family history of respiratory illness.

PURPOSE: This study aimed to develop a "Palliative Care Professional" education program and evaluate its effects on the recognition of good death, palliative care, and the meaning of life for nurses. METHODS: It was developed based on the hospice care program for volunteers being used in the Hospice Palliative Care Research Center of S University in Seoul. It was also based on the studies which investigated the educational needs of nurses in palliative care. This program consisted of 5 sessions and 16 content items for 2 weeks. A non-equivalent control group non-synchronized design was utilized and participants were assigned to the experimental group (n=42) or the control group (n=44). RESULTS: The recognition of a good death (F=11.44, p=.001), palliative care (F=4.15, p=.045), and the meaning of life (F=5.12, p=.026) increased more significantly for participants in the experimental group than in the control group. Participants felt that they gained further knowledge in palliative patient management and refined their clinical practice. CONCLUSION: The results of the study indicate that this program could serve as a practical program for palliative care nursing in the nursing field and suggests that more attention should be directed to the diverse educational needs of nurses.

Hand, foot and mouth disease, a distinctive clinical syndrome caused by a coxsackie virus, is clinically characterized by vesicles appearing on the hands, feet and in the mouth. The infection begins with a fever and mouth lesions consisting of small vesicles surrounded by red areolae on the buccal mucosa, tongue, soft palate and gingiva. The disease usually lasts spontaneously between 7 to 10 days after onset. We observed 20 cases of hand, foot, and mouth disease from July, 12th to September, 4th, 1979 and examined histopathologically and virologically. We have isolated only one viral strain showing cytopathic effect on HeLa cell among the five cases of acute stage and also observed that viral particle in the electronmicroscope.

PURPOSE: The purpose of this study was to identify risk factors of fall and to examine its results among patients aged 60 and over diagnosed with osteoporosis. METHODS: A retrospective descriptive survey was conducted with 91 patients admitted in a university hospital in a city. Data were collected using an interview method with a structured questionnaire, and were analyzed using descriptive statistics and multiple logistic regression. RESULTS: In patients with osteoporosis, the intrinsic risk factors of falls were aging (OR = 3.742), gait disturbance (OR = 12.565), taking one or fewer medicine (OR = 7.873), and having two or more diseases (OR = 5.173). The extrinsic risk factors included the use of a bed (OR = 3.093), slippery floors (OR = 12.130), bathroom mat without anti-slip rubber backing (OR = 3.564), and presence of a night light on the passage from the bedroom to the bathroom (OR = 2.980). CONCLUSION: For the elderly aged over 70 who are most vulnerable to falls, screening tests such as bone mineral density (BMD) should be conducted in health examinations and the risk of fracture caused by osteoporosis should be communicated to the vulnerable elderly. Besides, development of new exercise programs combining weightbearing exercise is needed to prevent bone loss and increase functional activities.

Lipoma arborescens is a rare intra-articular lesion consisting of a villous lipomatous proliferation of the synovial lining. We experienced one case of lipoma arborescens of knee which was associated with avascular necrosis of femoral head. This case report draws the attention to history, physical findings, MR images, pathologic findings and arthroscopic appearance of this rare lesion. Arthro;copically, the lesion appears as a synovial lesion with numerous fatty-appearing globules and villous projections. Although the etiology is unknown, lipoma arborescens has been described in association with osteoarthritis, rheumatoid arthritis and diabetes mellitus. MR imaging is diagnostic choice to differentiate the lesion from rheumatoid arthritis, pigmented villonodular synovitis and synovial chondromatosis in those patients who present with chronic, swollen and painfui joint. Arthroscopic removal was effective in this case and we think that treatment choice of this lesion is arthroscopic removal.

Mycobacterium marinum is a photochromogenic and slowly growing acid-fast organism classified in Runyon's group I of atypical mycobacteria. Infection with M. marinum occurs when the organism is inoculated usually in association with exposure to contaminated water and the disease is characteristically limited to the skin but deep soft tissue may be involved. We report a case of M. marinum infection in a 43-year-old man with erythematous verrucous plaque on his right knee, which was caused by a shell wound on a beach 3 months ago. The skin biopsy specimen showed pseudoepitheliomatous hyperplasia and several small epithelioid granulomas in the dermis. Culture of the tissue specimen revealed slowly growing whitish colonies in the dark, which changed yellowish after exposure to light. The microorganism was identified as M. marinum by biochemical tests, and was confirmed by the DNA-DNA hybridization method. The skin lesion disappeared after 3 moaths of treatment with minocycline, 200mg daily.
