Cortical metastasis usually occurs in the diaphysis of the long bones with the appearance of a cookie-bite pattern; this is associated with cortical destruction extending into the soft tissue as well as into the medullary cavity, or there can be a periosteal reaction. We report here on a 66-year-old woman who was diagnosed with intracortical metastasis in the proximal metaphysis of the right femur as an initial metastatic focus from primary lung cancer. CT detected an intracortical osteolytic lesion without cortical destruction or thickening. The MR images showed extensive peritumoral edema in the surrounding soft tissue and adjacent bone marrow edema, and this all mimicked osteoid osteoma.

Although ultrasonography is the most commonly used first-line imaging modality of the female pelvis because of diagnostic accuracy, low cost and safety, MRI is the best imaging modality of choice for the evaluation of the female pelvis. The indication of female pelvis MRI is diverse and includes the evaluation of Mullerian duct anomaly, differential diagnosis and characterization of uterine and ovarian tumors, and staging of malignant uterine and ovarian tumors. Understanding of MR protocols according to the specific gynecologic pathology allows accurate diagnosis and proper patient management.

Munchausen syndrome by proxy (MSBP) is a rare form of mental disorder and is known as a particular type of child abuse. MSBP has been described since 1977 as a severe form of abuse with illness falsification or the intentional harming by guardians, mostly mothers. The perpetrator of MSBP may inflict damage to the child directly or indirectly through medical procedures. The perpetrator’s alleged motive is to satisfy her psychological needs, and she has a history of mental illness, mostly, factitious disorder, personality disorder, and somatic disorder. The pathology is not well known; as such, it is difficult for medical personnel to detect it early. In addition, it is hard to be handled effectively by the police and child welfare agencies because of the scarcity of evidence. Therefore, the authors attempt to examine the essential information from early detection and child abuse prevention by analyzing its clinical characteristics and the perpetrator’s characteristics, including alerting signs of MSBP. For this purpose, we focus on the role of nursing staff to detect this unusual cause of child abuse.

The anterior clinoid process may be pneumatized by an extension of the sphenoid sinus air space. An anterior clinoid mucocele is a particularly rare entity, which can lead to optic complication due to its proximity to the optic nerve. Optic neuropathy is seldom recoverd if there is a delay in treatment for more than 10 days. The primary treatment for mucocele is surgical excision. We report a patient with mucocele of the anterior clinoid process that resulted in recurrent monocular visual loss. The patient underwent endoscopy-assisted transnasal marsupialization of mucocele with full recovery of visual function.

OBJECTIVES: Rapid economic growth and industrial development in South Korea have led to a great change in dietary patterns, and the use of convenience foods has continuously increased. This study was performed to evaluate the energy and nutrient contents of convenience foods at convenience stores near the universities as a meal. METHODS: Data was collected by visiting 22 convenience stores near some universities in Chungbuk and Seoul and by checking nutrition labels on convenience foods at the stores. Data of a total of 338 food items were collected, and divided into five groups according to the food categories; rice products (n=156), noodles (n=101), burger/sandwiches (n=62), Tteokbokkis (n=11), and dumplings (n=8). Further, rice products, noodles, and burger/sandwiches were divided into subcategories. RESULTS: The proportion of calories from carbohydrates was high in the rice products and tteokbokki, while the rate of calories from fat was high in burger/sandwiches and dumplings. Among the rice products, the proportion of carbohydrate calories was high in a one-dish food, rice with soup, and triangular kimbap, while the proportion of calories from fat in lunch boxes was high. In the noodles category, ramyeon and spaghetti had a high percentage of fat calories, while udong had a high percentage of carbohydrate calories. The ratio of the calorie content in relation to the KDRIs for adults aged 19-29 years, lunch boxes provided about 1/3 of daily required energy. However, the amount of calories as one meal was not enough for other types of rice products except for lunch boxes. Ramyeon was high in calories, fat, and sodium, but low in protein content. The burger/sandwiches had a high percentage of fat and sodium. CONCLUSIONS: Our results showed several nutritional limitations of convenience meals in convenience stores according to the type of food. Therefore, college students should limit excessive intake of convenience meals on a regular basis in order to avoid unhealthy food intake patterns. Our results demonstrate the need for educating college students with regard to checking nutrition labels when choosing convenience meals in order to facilitate the selection of food items that contribute to a balanced diet.

UG0712 is a new ginsenoside extract processed from ginseng leaves. A subchronic toxicity study of UG0712 was conducted in male and female SD rats. Rats were treated with UG0712 at doses of 100, 400 and 1,600 mg/kg/day for 13 weeks, and observed followed by 4-week recovery period at a highest dose. No-treatment-related effects were observed regarding the mortality, ophthalmic examination, urinalysis and histopathology. Although the changes in clinical sign, body weight, organ weight, hematology, and serum biochemistry were observed, they were temporal and pharmacological effects. Based on the present experiment conditions, the no observed adverse effect level was considered to be more than 1,600 mg/kg/day in both sexes of rats.

We report a case of cribriform-morular variant of papillary thyroid carcinoma associated with familial adenomatous polyposis. A 21-year-old woman presented with multiple, well-defined, oval shaped thyroid nodules, which showed hypo-echoic and solid mixed with some cystic components by ultrasound, and poorly enhancing and low dense by CT scan. Cytological finding was compatible with papillary carcinoma. Total thyroidectomy was performed and nodules were palated soft. Histologic analysis confirmed the diagnosis of cribriform-morular variant of papillary thyroid carcinoma. Familial adenomatous polyposis, thereafter, was diagnosed by family history and colonoscopy, and preventive colectomy was performed.

OBJECTIVE: To investigate associations between stress, resilience, and burnout in three emotional job sectors. METHODS: We conducted a multi-group comparative study using structural equation modeling and latent mean analysis. In total, 806 participants (403 call center consultants, 270 mental health workers, and 133 school counselors) completed self-administered questionnaires including the Perceived Stress Scale, Korean version of the Connor-Davidson Resilience Scale, and Maslach Burnout Inventory-General Survey. RESULTS: Stress had significant direct effects on resilience and burnout, and resilience had significant direct effects on burnout in all groups. Resilience partially mediated these relationships among call center consultants and school counselors. Stress and burnout were highest in call center consultants, followed, in order, by mental health workers and school counselors. Resilience was highest in school counselors, followed, in order, by mental health workers and call center consultants. The effect size of the latent mean difference was highest for burnout, followed, in order, by resilience and stress. CONCLUSION: Our findings suggest that stress caused by emotional labor can contribute to burnout. Interventions targeted at different sectors are needed to reduce burnout.

Objective: The endothelial inflammatory response plays an important role in atherogenesis by inducing nuclear factor (NF)κB-dependent cell adhesion molecule expression and monocyte recruitment. Here, we screened for natural ligands and investigated the ability of shinjulactone A to inhibit interleukin-1β (IL-1β)-induced endothelial inflammatory signaling. Methods: The natural compound library included 880 single compounds isolated from medicinal plants by the Korean Medicinal Material Bank. Primary endothelial cells were pretreated with single compounds before stimulation with IL-1β to induce endothelial inflammation. Endothelial inflammation was measured by assaying NFκB activation and monocyte adhesion. The endothelial-mesenchymal transition (EndMT) was evaluated using cell type-specific marker protein expression and morphology. Results: Shinjulactone A was identified as an efficient blocker of IL-1β -induced NFκB activation, with a half-maximal inhibitory concentration of approximately 1 µM, and monocyte recruitment in endothelial cells. However, it did not affect lipopolysaccharideinduced NFκB activation in macrophages. Compared to Bay 11-782, a well-known NFκB inhibitor that shows considerable cytotoxicity during long-term treatment, shinjulactone A did not affect endothelial cell viability. Furthermore, it also significantly inhibited the EndMT, which is known to promote atherosclerosis and plaque instability. Conclusion We suggest that shinjulactone A may be an effective and safe drug candidate for atherosclerosis because it targets and inhibits both endothelial inflammation and the EndMT, without impairing NFκB-dependent innate immunity in macrophages.
