In Asia, mammography following the injection of foreign materials into the breasts for cosmetic augmentation is frequently seen and diagnosis based on the typical radiologic findings is straightforward. We report the unusual radiologic findings in two patients with foreign body granulomas caused by injected foreign materials and discovered incidentally during screening work up. The mammographic findings were bilateral, hyperdense, spiculated masses, with occasional microcalcification, and at sonography, markedly hypoechoic, spiculated solid masses, located near the pectoralis muscle and partly extending into it, were observed. These radiologic findings mimicked malignancy.

Purpose: The purpose of this study was to describe characteristics of colleges implementing the accelerated second-degree bachelor of science in nursing program in South Korea and provide insight into strategies to improve the program outcomes. Methods: An on-line questionnaire developed for this study was emailed to deans of nursing colleges who were members of the Korean Association of College of Nursing. Questions included items related to nursing college, students, curriculum, and anticipated difficulty in relation to an increase of the number of second-degree students. Results: Out of 117 nursing schools, 33 schools (28.2%) participated in the on-line survey. The actual number of second-degree students and their ratio (about 10%) to regular students significantly increased in 2019. Male students were enrolled nearly twice as many times as regular students. Among the anticipated difficulties, clinical practice institutions (3.94) and clinical practice instructors (3.73) showed relatively higher scores than other difficulties such as teaching (3.58) and education facilities (3.30). Conclusion In order to improve the quality of nursing education for second-degree students, more nursing faculties and innovative clinical practice support systems are needed. Future study is warranted to investigate the educational experience of second-degree students and graduates.

PURPOSE: This study was performed to evaluate MR signal intensity(SI) of calcification and to assess the capability of MRI in detection of various intracranial calcifications. MATERIALS AND METHODS: The MR findings and ROI value of experimental model of calcium carbonate suspension according to each concentration (20, 35, 50%) and diameter (1-10 mm) and hydroxyapatite suspension according to each concentration (10, 20, 30, 40, 50%) were analyzed. A specimen of calcification in cranio-pharyngioma was analyzed for its composition by XRD(X-ray diffractometer) and ICP(inductively coupled plasma) methods. MRI of 34 patients with intracranial calcifications were retrospectively analyzed for signal intensity of the calcification and its capability to detect calcifications according to size, location, and contrast with adjacent lesion. RESULTS: The calcium carbonate phantom with larger diameter and low concentration showed lower signal intensity on T2 than TlWl. Hydroxyapatite phantom showed high signal intensity in 10-30% concentration and low signal intensity in 40-50% concentration on T1 weighted image. The 5 cases of 34 intracranial calcifications showed high signal intensity on T1 weighted image. The capability of MRI in the detection of intracranial calcifications decreased in the circumstances such as small size(<2.5mm) and intraventricular location. Although the size of calcification was small, the detection was easy in the good contrast with adjacent lesion. However, the detection of the small sized calcification was easy if the contrast with adjacent lesion was good. CONCLUSION: lntracranial calcification shows generally low signal intensity on T1 and T2 weighted image with the exception of occasional high SI on TlWl. Detection of intracranial calcification in MRI is affected by its composition, size, location, and contrast with adjcent lesion.

The authors analyzed 38 consecutive cases with an occipital arteriovenous malformation(AVM) in regard to visual field defect. The incidence of occipital AVM was 10.4% among 367 patients with a cerebral AVM treated between 1975 and 1994 in our institute. Bleeding rate of occipital AVM in this series was 86.8%(EE cases) and it was significantly higher than that of AVM in other locations. Of 38cases, 15 patients(39.5%) had a visual field defect on admission and all of them were accompanied by intracerebral hematomas caused by the rupture of AVMs. The presence of visual field defect did not correlate with angioarchitecture in reference to pattern of nidus, feeding artery, and draining vein. Of 15 patients with visual field defect. 10 patients showed homonymous hemianopsia and five patients, homonymous quadrantanopsia. The size and location of intracerebral hematoma correlated well with hemispheric approach : 11, parietooccipital approach : 10, with six preoperative embolization and 1 postoperative gamma knife surgery. Fifteen patients underwent gamma knife surgery with five preoperative embolization. One patient underwent embolization only. The results of treatment were as follows : There were no mortality and morbidity except for visual field defect. We confirmed complete resection or obliteration of malformed vessels in 25 patients and reduction of the nidus size in eight patients. Five patients were not followed. After gamma knife surgery, two patients showed rebleeding during the follow up period. Among 23 patients who had no visual field defect before treatment, three patients showed visual field defect after treatment(one after microsurgical resection using occipital interhemispheric approach, two after preoperative embolization). In 15 patients with visual field defect before treatment, four patients showed improvement in their visual field defect after treatment(three after microsurgical resection using occipital interhemispheric approach, one after gamma knife surgery). The parietooccipital approach did not change the status of visual field in any of the ten parients. In occipital AVM, visual field defect was the most srious morbidity. Ruptured occipital AVM had a higher incidence of hemorrhage causing a visual field defect and had a higher indication of direct surgical approach than AVM of other location. In planning surgery of occipital AVM, one has to count microsurgical anatomy based on the visual pathway as well as clinical findings such as the angioarchitecture, location of intracerebral hematoma, and preopeative visual field.

A case of recanalization of totally thrombosed giant aneurysm is reported. The authors describe a 18 year-old female who developed headache, vomiting, and intermittent diplopia with left side ptosis. The brain CT scan and MRI revealed a totally thrombosed giant aneurysm with acute and subacute hemorrhage, located anterior to the left suprasellar cistern. Angiographic finding was non-visualization of the left posteior cerebral artery distal to the P2 segment, and the neck of the aneurysm was not identified. Follow-up angiography taken one month later showed partial recanalization of the thrombosed aneurysm. A probable mechanism of growth, thrombosis, and recanalization, of the giant aneurysms are discussed.

PURPOSE: This research was aimed at evaluating the differences in depression by skinfold thickness, and the relationship between two variables. METHODS: Research design was a non-experimental descriptive survey. Using a caliper, we measured skinfold thickness on the triceps, and then on the suprailiac, and the mid-thigh. Depression was evaluated using the Geriatric Depression Scale-Short Form (GDS-SF). Data were collected for one month from Sept 1st to 30th, 2011. There were 52 subjects, 25 of which were from elderly welfare centers and 27 were hospitalized. RESULTS: Subjects were an average age of 76.4+/-4.45, and the incidence rate of depression (> or =6) was 36.5% and those who had a sum of 3 skinfolds over 62 mm were 22.7%. The GDS-SF was significantly different in only the suprailiac skinfold thickness (F=7.25, p<.05). CONCLUSION: Findings indicate that depression is different based on suprailiac thickness in older adult women at elderly welfare centers and those who were hospitalized in an medical ward. It suggests that the suprailiac skinfold may be an indicator of abdominal obesity when considering depression in elderly women. Further study is needed to evaluate a cutoff score of skinfold thickness in obesity for older adult women.
