PURPOSE: To evaluate the US findings of soft tissue hemangiomas in extremities and to correlate the echo-pattern with MR signal characteristics of hemangiomas. MATERIALS AND METHODS: We retrospectively studied forty-two patients either with pathologically proven cases or with characteristic features of hemangiomas on MRI, US and plain film. Hemangiomas were divided into two types according to the locations;subcutaneous and intramuscular. Analytic points on US and MR findings were gross morphology of the mass, internal echo-pattern or signal characteristics. We correlated the echo-pattern with MR signal characteristics in hemangiomas. RESULTS: Subcutaneous hemangiomas revealed homogeneously anechoic mass on US, which were well correlated with MR signal characteristics' homogeneous low singnal intensity(SI) on Tl-weighted image(WI) and high SI on T2-WI. Intramuscular hemangiomas showed heterogeneously mixed echoic masses on US. An anechoic component on US corresponded to dilated vascular channels on MRI. The signal intensity of intramuscular hemangioma was less than that of subcutaneous fat on T1-WI and greater than that of fat on T2-WI. Both types of hemangiomas had tubular or lace-like appearance with interspersed fibrofatty septa. CONCLUSION: The echo-patterns in US were well associated with MR signal characteristics on MRI. Regarding US and MR features, intramuscular hemangiomas were different to subcutaneous hemangiomas.

Purpose: Rapid changes have occurred in the educational environment of colleges since the outbreak of COVID-19. This study was conducted to determine the factors influencing college life adaptation for nursing students. Methods: The participants included 124 nursing students. A self-administered online questionnaire, available from March 30 to April 10, 2022, was used for data collection. The online questionnaires included COVID-19 stress, interpersonal relations, information literacy, and college life adaptation. Statistical analysis was performed using t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. Results: The average score for adapting to college life was 3.32±0.58. Significant differences in college life adaptation were found based on the number of exercise days per week (F=3.62, p=.015), regular daily routine (t=-3.41, p<.001), amount of sleep (t=-3.61, p<.001), sleep quality (t=-3.90, p<.001), and diagnostic self evaluation (F=19.55, p<.001). Factors that influenced college life adaptation included interpersonal relations (β=.36, p<.001), diagnostic self evaluation (good) (β=.48, p<.001), diagnostic self evaluation (fair) (β=.38, p=.005), and COVID-19 stress (β=-.11, p=.027), which explained 38.0% of the college life adaptation. Conclusion Development of a program that integrates interpersonal relations, diagnostic self- evaluation, and COVID-19 stress for nursing students is recommended to improve college life adaptation.

Renal calcifications are a recognized complication of furosemide therapy in premature infants. Particularly in infants with chronic lung disease, the use of this potent diuretic is associated with hypercalciuria, which may predispose the infant to medullary nephrocalcinosis and renal calculi, We experienced two cases of nephrocalcinosis in very low birth weight infants. One had bronchopulmonary dysplasia, pneumonia, patent ductus arteriosus, ventricular septal defect and congestive heart failure and the other had systemic cytomegalovirus infection with cytomegalovirus pneumonitis and ricket of prematurity. Both patients received a large amount of furosemide. We presented these cases with brief review of literatures.

PURPOSE: To evaluate MR characteristics of periosteal reactions and subperiosteal abscesses in osteomyelitis as compared with radiographs. MATERIALS AND METHODS: We retrospectively reviewed 28 patients(18 males, 10 females) with osteomyelitis. Nineteen patients underwent MR imaging with 0.5 T. We analyzed for morphologic patterns, intervals of appearance and disappearance of periosteal reactions after symptom onset. Twenty-three patients were confirmed by surgery and 5 patients by the radiologic findings, clinical and laboratory data. RESULTS: Periosteal reaction appeared as low signal intensity arc on the T1- and T2-weighted axial images. In 3-7 days after symptom onset, periosteal reactions and subperiosteal abscesses were noted on MR imaging, and only two of eleven patients were noted in radiographs. Periosteal reactions of 8-14 days after symptom onset were demonstrated in all of 13 patient on MR, and 9 on plain radiographs. All patients with 2 weeks after symptom onset showed perioste.al reaction in plain film and MR. The periosteal reactions persisted until approximately 2 to 3 months after treatment on follow up radiographs. CONCLUSION: Periosteal reactions in osteomyelitis are detected on the MR imaging earlier than plain film. MR is valuable in detecting subperiosteal abscess which is not appecent in simple radiographs. Periosteal reactions can be seen on MR in 3 days after symptom onset and persist for 2-3 months after treatment.

PURPOSE: To describe the radiographic and MR characteristics of subacute diaphyseal osteomyelitis of the long bone. MATERIALS AND METHODS: We retrospectively analyzed plain radiographs and MR images in nine children and two young adults with surgically-proven diaphyseal osteomyelitis of the long bones. MR imaging was carried out before and after Gd-DPTA administration. Patients charts were reviewed for clinical and laboratory data and histologic correlation was available in all cases. RESULTS: All patients had a history of a minimum of 2 weeks' duration. All presented with an insidious onset of mild pain; they showed apyrexia and normal erythrocyte sedimentation rate. In all patients, plain radiographs showed single or multiple linear periosteal reaction with cortical irregularity. Medullary abnormality was not found except in one case which showed an abscess cavity. MR images revealed thickening or irregularity of the cortex, periosteal reaction, bone marrow signal alteration, and perilesional edema. CONCLUSION: Subacute diaphyseal osteomyelitis of the long bone is broadly based on the cortex, and elicits more sclerosis and periosteal reaction. Familarity with plain radiographs and MR features may be useful in the diagnosis of subacute diaphyseal osteomyelitis.

OBJECTIVE: To evaluate the predictive factors associated with the success of medical abortion by misoprostol monotherapy within 24 hours in the first trimester of pregnancy. METHODS: The records of 228 women with miscarriage up to 11 weeks of gestational age who underwent medical abortion by intravaginal misoprostol monotherapy were reviewed. Success of abortion was defined as complete expulsion of the conceptus without the need for surgical intervention. Outcomes of interest were success of abortion within 24 hours following administration of misoprostol. RESULTS: Among 222 women who continued the process of medical abortion for 24 hours, 209 (94.1%) had a successfully completed abortion. Multivariate logistic regression showed that serum β-human chorionic gonadotropin (β-hCG) above 40,000 mIU/mL is significantly associated with failed medical abortion within 24 hours (odds ratio [OR], 7.13; 95% confidence interval [CI], 1.60–37.32; P=0.011). The area under the receiver operating characteristic curve of β-hCG level associated with successful abortion within 24 hours was 0.705 (95% CI, 0.63–0.77; P=0.007). Previous vaginal delivery seems to be significantly associated with successful abortion within 24 hours on univariate analysis (P=0.037), but the association was lost in multivariate analysis. CONCLUSION: Misoprostol monotherapy has a high success rate for first trimester abortion. Women with serum β-hCG less than 40,000 mIU/mL are likely to achieve a successful abortion within 24 hours after intravaginal administration of misoprostol.

OBJECTIVE: To evaluate the findings of brain MRI in patients with carbon disulfide poisoning. MATERIALS AND METHODS: Ninety-one patients who had suffered carbon disulfide poisoning [male:female=87:4; age, 32-74 (mean 53.3) years] were included in this study. To determine the extent of white matter hyperintensity (Grade 0-V) and lacunar infarction, T2-weighted MR imaging of the brain was performed. RESULTS: T2-weighted images depicted white matter hyperintensity in 70 patients (76.9%) and lacunar infarcts in 27 (29.7%). CONCLUSION: In these patients, the prevalent findings at T2-weighted MR imaging of the brain were white matter hyperintensity and lacunar infarcts. Disturbance of the cardiovascular system by carbon disulfide might account for these results.

Autoimmune progesterone dermatitis is a rare cyclic premenstrual reaction to a variety of progesterone produced during the luteal phase of a woman's menstrual cycle, including urticaria, urticarial papule, papulovesicle, eczematous lesion, erythema multiforme, and progesterone-induced anaphylaxis. A 23-year-old woman presented with brown colored hyperpigmented reticular patches on the chest and abdomen. Since the age of 20, she had been recurrently suffering from pruritic eruption that appeared regularly 5 to 10 days prior to menstruation and persisted for several days. Intradermal skin test reaction to progesterone was positive. These features were consistent with the diagnosis of autoimmune progesterone dermatitis.
