The term malignant mesenchymoma has been applied to those tumors of the soft tissue of mesenchymal origin which are composed of tumor cells differentiating into two or more unrelated malignant forms in addition to the fibrosarcomatous element. Recently authors experienced a case of malignant mesenchymoma in the right axillary area. Microscopically the sarcoma revealed multiple pattern of differentiation, including liposarcoma, malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma and rhabdomyoblastoma. The presence of rhabdomyblastic cells were proved by immunochemical study utilizing desmin. This patient was treated with surgical excision and radiation.

PURPOSE: A scoring system could be clinically useful in determining cases in which a throat culture may be omitted or in cases whether antibiotics may be initiated or not. We propose to make a clinical guideline of antibiotics administration in patients with pharyngitis. METHODS: From Apr. 1996. to Mar. 1997, throat cultures were taken from 321 cases (72 cases from Kyung-Hee Medical Center, 249 cases from 3 local pediatric clinics). On the first day of visit, 9 clinical items on a score-card were checked and a tentative diagnosis for streptococcal or non-streptococcal infection was made. These clinical scores were compared with the results of the throat swab cultures. RESULTS: Of 321 cases with pharyngitis, 55 cases (17%) proved to have group A streptococci by throat culture. The positive culture rate of group A streptococci was 18.5% from 3 local pediatric clinics, and 12.5% from Kyung-Hee Medical Center. The positive culture rate of group A streptococci were 40% in above 31 points of score, 31.5% in 29 to 30 points, 20.5% in 27 to 28 points. The sensitivity and specificity of the scoring system using a score at least 28 above points were 71% and 67%, respectively. CONCLUSION: The clinical diagnosis of streptococcal pharyngitis indicates that patients age 5 to 10 years, findings of abnormal pharynx, high fever and no past history of antibiotics use. Further modification of the scoring system for diagnosis of streptococcal pharyngitis should be made to prevent antibiotics abuse and correct diagnosis of pharyngitis.

This study was conducted to investigate the factors related to the poor school performance of the elementary school children. Two schools in Taegu, one in the affluent area and the other in the poor area, were selected and a total of 175 children whose school performance was within low 10 percentile(poor performers) and 97 children whose school performance were within high 5 percentile(good performers) in each class of 2nd, 4th and 6th grades were tested for the physical health, behavioral problem and family background. Each child had gone through a battery of tests including visual and hearing acuity, anthropometry(body weight, height, head circumference), intelligence(Kodae Stanford-Binet test), test anxiety(TAI-K), neurologic examination by a developmental pediatrician and heavy metal content(Pb, Cd, Zn) in hair by atomic absorption spectrophotometry. A questionnaire was administered to the mothers for prenatal and perinatal courses of the child, family environment, child's developmental history, and child's behavioral and learning problems. Another questionnaire was administered to the teachers of the children for the child's family background, arithmatic and language abilities and behavioral problem. The poor school performance had a significant correlation with male gender, high birth order, broken home, low educational and occupational levels of parents, visual problem, high test anxiety score, attention deficit hyperactivity disorder(ADHD), poor physical growth(weight, height, head circumference) and low I.Q. score. The factors that had a significant correlation with the poor school performance in multiple logistic regression analysis were child's birth order(odds ratio=2.06), male gender(odds ratio=5.91), broken home(odds ratio=9.29), test anxiety score(odds ratio=1.07), ADHD(odds ratio=9.67), I.Q. score(odds ratio=0.85) and height less than Korean standard mean-1 S. D.(odds ratio=11.12). The heavy metal contents in hair did not show any significant correlation with poor school performance. However the lead and cadmium contents were high in males than in females. The lead content was negatively correlated with child's grade(p<0.05) and zinc was positively correlated with grade(p<0.05). Among the factors that showed a significant correlation with the poor school performance, high birth order, short stature and ADHD may be modified by a good family planning, good feeding practice for infant and child, and early detection and treatment of ADHD. Also, teacher and parents should restrain themselves from inducing excessive test anxiety by forcing the child to study and over-expecting beyond the child's intellectual capability.

PURPOSE: To evaluate the radioloic findings of malignant retroperitoneal fibrosis. MATERIALS AND METHODS: Post-contrast CT (n=9) and urographic (n=7) findings of nine patients with malignant retroperitoneal fibrosis were retrospectively analyzed. Primary tumors were found to be advanced gastric cancer (n=6), early gastric cancer (n=1), breast cancer (n=1), and cervical cancer (n=1). We analyzed CT findings with regard to the site of soft tissue lesion, ureteral involvement, the presence or absence of hydronephrosis, and distant metastasis. The level and length of ureteral involvement, presence or abscence of ureteral stenosis, and ureteral displacement as seen on urography, were analyzed. RESULTS: On CT scans, enhanced soft tissue lesions (mass, 5 cases; plaque, 4 cases) encircling the abdominal aorta and IVC were noted in all cases. Thickening of the ureteral wall (n=8), hydronephrosis (n=9), and enlarged lymph node (n=5) were also seen. On urography, irregular stenosis and medial displacement of ureters from level L2 to S2 were noted in all cases. The length of ureteral involvement was 4-6.5cm. CONCLUSION: The common CT findings of malignant retroperitoneal fibrosis were enhanced soft tissue lesion encircling the abdominal aorta and IVC, hydronephrosis, and thickening of the ureteral wall. On urography, ureteral stenosis and medial displacement were seen.

For producing large numbers of professional nurses who could manage 21th century's human health, it is necessary to review the direction of registered nursed' national examination which evaluates the nursing education and is granted a licence. For adapting to social expectation of the nurse, we have to nurture the nurses' problem solving capability in clinical setting. Seven divisions of Korean Academy of Nursing suggested clinical competency according to their categories. This paper was presented in the workshop for setting up direction of registered nurses' national examination. We expect that this paper would be more refine and confirm through reviewing subdivisions' learning objectives and discussing clinical minimum level of competence contents with clinical leaders.

PURPOSE: Diagnosis of a hemodynamically significant patent ductus arteriosus (PDA) that should be treated is difficult to determine by clinical and echocardiographic examination. The purpose of this study is to clarify the usefulness of diastolic flow velocity (DFV) of the left pulmonary artery (LPA) determined by echocardiography in the assessment of significant PDA in preterm infants. METHODS: Clinical and echocardiographic findings, including DFV in LPA, of PDA were evaluated at 24 hours, 48-72 hours of age and after indomethacin treatment in thirty-nine infants ranging from 25 to 34 gestational weeks of age. DFVs of the study group (N=13) with significant PDA were compared with those of healthy control group (N=26) without significant PDA. RESULTS: DFVs in healthy preterm infants were high in the first few days and were significantly decreased after spontaneous ductal closure. DFVs in preterm infants with significant PDA who underwent indomethacin treatment were significantly higher than that of healthy control infants. After indomethacin treatment, DFVs in this study group remained high with continuing significant PDA and markedly decreased with disappearance of significant PDA. Until ductus arteriosus closed, DFVs showed a significant correlation with the magnitudes of ductal shunt. A cutoff value for DFV of 30 cm/sec showed a sensitivity of 77% and a specificity of 92% as a predictor of significnat PDA in preterm infants. CONCLUSION: Measurement of DFV in LPA by echocardiography is a useful method for assessing the significnat PDA which may require treatment in preterm infants.

Papillary thyroid carcinomas are the most common type of thyroid malignancy, and have more excellent prognosis compared to other types of thyroid malignancy, with rare occurrences of distant metastasis. The most frequent sites for distant metastases are the lungs and bones, but brain metastases are extremely rare, with a frequency of only 0.1~5% in reported series. Hence we report a patient with a papillary thyroid carcinoma metastasis to the right parietal lobe of brain, the lung, the left chest wall and right acetabulum, with a review of the literature.

One of the most interesting congenital malformations is a conjoined twin. Conjoined twins are a rare occurrence in obstetric practice. More commonly known as Siamese twins, this phenomenon is shrouded in mystery and considered a curiosity by general public. Current technology is providing a basis for earlier diagnosis and a better prognosis. Frequently, the twins are born dead, but there are a few cases in which the twins survive. We present a case of thoraco-omphalophagus with omphalocele in 35 years old woman at 25weeks 5 days gestation by 3-D ultrasonography and MRI.
