Sclerosing stromal tumor (SST) is a rare benign ovarian neoplasm and predominantly affects young women in the second and third decades with distinctive clinical features like irregular mensturation and dysmenorrhea. SST is usually solid and the possibility of malignancy should be considered. Recently some authors reported it is possible to predict the presence of this tumor preoperatively on the basis of the contrast enhanced magnetic resonance imaging (MRI) findings. We experienced a case of sclerosing stromal tumor of the ovary with characteristic clinical, pathologic and radiologic findings. We report this case with a brief review of the literature.

BACKGROUND: The usage of appropriate disinfectants is essential for infection control in a hospital. Inadequate use of disinfectants is the cause of human or environmental toxicity and is a waste of cost. The objective of this study was to describe the status of the usage of disinfectants in Korean hospitals. METHOD: One hundred and eighty three hospitals of over 300 beds were investigated by a questionnaire distributed by mall. Data collection was done on November 1999. The questionnaire was made by the Association of Infection Control Nurses in Korea, based on references and protocols of the Korean Society of Nosocomial Infection Control. Numerical and percentage data were analyzed by SPSS. RESULTS: The collection rate of the questionnaire was 43.7% (80/300). Thirty five hospitals (46.7%) had an official process in selecting disinfectants in their hospitals. Regarding skin antiseptics, 10% povidone iodine and 70% alcohol were commonly used in skin preparation for intravenous catheterization or pre-operative skin disinfection, For disinfection of mucosal membranes such as mouth and periurethral area, 3% boric acid solution or 3% H202 were used. Most of the hospitals decontaminated contaminated medical instruments manually with dodecyl diamino ethyl glycine (20.8%). glutaraldehyde (15.6%). quaternary ammonium compounds (13.8%), virkon (12.3%) and sodium hypochlorites (11.7%). Glutaraldehyde and virkon were frequently used for disinfection of endoscopes. Sodium hypochlorites (48.9%) and quaternary ammonium compounds (19.8%) were the most commonly used environmental disinfectants. Some noticeable problems in disinfectants were as follows. First, for mouth care, many hospitals (41.7%) over-used boric acid, which has cumulative toxicity for humans. Second, many hospitals had an incorrect protocol of disinfecting endoscopes. Third, for environmental decontamination and instrument cleaning, some hospitals used high level disinfectants such as glutaraldehyde, which is too costly and provides unnecessary safety problems. Fourth, after patient discharge, many hospitals did not use disinfectants at all. Considering the specific Korean medical environment of high incidence of multi-drug resistant microorganisms, use of disinfectants for discharged environments may be warranted. CONCLUSION: This study included only hospitals of over 300 beds, which has a limitation in representing the status of disinfectants usage in a country. However, significant problems from misunderstanding the basic principles of disinfectants and misusages of disinfectants were observed in this investigation. These observations will provide useful information for designing a guideline for the appropriate uses and for efficient education of disinfectants, and also for planning a national control program for proper disinfectants usage in this country.

BACKGROUND: The aims of this study were to test if amrinone or milrinone reverses cardiac depression induced by the exposure to isoflurane in the isolated heart and to determine whether amrinone or milrinone dilates the coronary artery directly. METHODS: Using the isolated Sprague-Dawley rat hearts, heart rate, left ventricular pressure, dp/dt (differentiated rate of pressure development), O2 delivery(DO2), myocardial oxygen consumption(MVO2), and percent O2 extraction were measured. After the isolated hearts were exposed to isoflurane at 1.2 vol% during 10 min, amrinone(10, 50, 100 M) or milrinone(1, 5, 10 M) was separately given to six groups. RESULTS: Amrinone and milrinone reversed, not statistically significant, the depression of cardiac contractility induced by isoflurane, while the isoflurane-induced bradycardia substantially returned to normal by amrinone 100 M. And amrinone and milrinone elevated coronary flow, DO2, MVO2, while isoflurane increased in coronary flow and DO2, except MVO2. CONCLUSIONS: These results suggest that amrinone and milrinone did not counteract the isoflurane-induced cardiac depression and indirectly increased in coronary blood flow through the elevation of cardiac work.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.

The purpose of this study was to identify nursing interventions performed by neonatal nursing unit nurses. For data collection this study used the taxonomy of Nursing Intervention Classification(NIC : 486 nursing intervention) which was modified by McCloskey & Bulecheck(2000). The new 58 nursing interventions was translated into Korean, and then modified by pannel group, which consist of clinical experts and nursing scholars and finally the 419 nursing interventions was selected. The data were collected from 112 nurses. 168 nursing interventions were performed at least monthly by 50% or more of the nurses. The high frequency of performed nursing interventions were Family domain. 37 nursing interventions were performed at least once a day. The nursing interventions receiving the highest item mean score were neonatal care, neonatal monitoring, phototherapy; neonate, bottle feeding and temperature regulation. 56 nursing interventions were rarely performed by 90% or more of the nurses. Most of them were in the behavioral domain. The rarely used interventions were urinary bladder training, art therapy, religious addiction prevention, religious ritual enhancement and bladder irrigation. Therefore, neonatal nursing units nurses used interventions in the Physiological: basic domain most often on a daily basis and the interventions in the behavioral domain least often. These findings will help in building of a standardized language for the neonatal nursing units and enhance the quality of nursing care. Further study will be needed to classify each intervention class and nursing activity and validate NIC in pediatric care unit.

Osteoblastoma is a rare tumor which forms osteoid and bone with highly vascular stroma, account for less than 1 percent of all bone tumors. The lesion had been though to be controlled with curettage and local excision. In recent years, osteoblastomas have been described as aggressive osteoblastoma or malignant osteoblastoma, separated from the innocuous behavior of usual osteoblastoma. It represents the histologic characteristics of the presence of epithelioid osteoblasts, trabecular rather than lace-like osteoid, low mitotic rate with no atypical form with prominent giant cells of osteoclastic type. The differential diagnosis between aggressibe osteoblastoma and osteogenic sarcoma is extremely difficult, but its peculiar histologic pattern and its different clinical and radiologic features and better prognosis are helpful. We report here a case of aggressive osteoblastoma of 17 years old female patient with 3 years and 4 months follow-up period and review the literature.

The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma, true osteochondroma which arises from bone. One case of soft tissue osteochondroma in the knee, a lesion of uncertain pathogenesis is reported.

The purpose of this study was to investigate life stress and resilience levels, and the relationship between life stress and resilience among dental hygiene students. From July 11, 2016 to July 29, 2016, questionnaires were used to survey dental hygiene students in several areas, after which the data collected from 274 questionnaires were analyzed with IBM SPSS Statistics ver. 21.0 for Windows. The results showed a significant negative correlation between life stress and resilience for dental hygiene students in all factors (p<0.05, p<0.001). This means that higher the resilience, the lower the life stress. Therefore, it is necessary to enhance resilience as a preventive dimension and develop associated program to help dental hygiene students cope with life stress.
