Ovarian mature cystic teratoma containing benign prostatic tissue is rare and only 11 cases have been reported in the literature to date. We report a case of mature cystic teratoma of the ovary containing prostatic tissue. A 23-year-old female patient came to our hospital complaining of irregular menstruation for 3 months. Her menarche had occurred when she was 13 years old. The patient showed no evidence of virilization nor of endocrinopathy. A goose-egg-sized mass was palpable in the left lower abdomen on physical examination. Ultrasonography revealed a cystic ovarian mass with internal echogenecity. Microscopic finding was consistent with that of usual mature cystic teratoma except for a 1.5 cm focus of prostatic and bladder tissues. Prostatic tissue demonstrated strong immunoreactivity for prostatic specific antigen (PSA), prostatic alkaline phosphatase (PAP) and cytokeratin 7. Basal cells of the prostate glands were positive for high molecular weight cytokeratin (34betaE12). Although ovarian mature cystic teratoma containing prostatic tissue has been reported as a rare occurrence, a careful examination with immunohistochemical staining may increase the detection of prostatic tissue in mature cystic teratoma of the ovary.

BACKGROUND: To identify the expression patterns and usefulness of various antibodies in making diagnoses and predicting prognoses, an immunohistochemical study was performed on thymic epithelial tumors (TETs). METHODS: Forty-two cases of TETs were reclassified according to the new World Health Organization (WHO) classifications. CD3, CD5, CD79a, CD99, pan-, high- and low-molecular weight cytokeratins, EMA, vimentin, MIB-1 (Ki67) and p53 immunostaining were carried out. RESULTS: There were two, twelve, eight, two, thirteen and one case for type A, AB, B1, B2, B3 and C, respectively. Combined B1/B2 and B2/B3 were 2 cases each. Fourteen cases (33.3%) had myasthenia gravis. CD99 was immunoreactive mainly in cortically derived lymphocytes, while CD3 and CD5 were immunoreactive in medullary-derived lymphocytes. CD5 immunoreactivity was negative in all thymic epithelial cells, except for one case of type B3. MIB-1 indices were highly expressed in cortical lymphocytes and some thymic epithelial cells, but did not show any correlation with grades. p53 in thymic epithelial cells was expressed in 6 (46%) out of 13 cases of type B3 and one case of type C, and it was negative in all other subtypes. CONCLUSIONS: Only p53 was helpful for predicting high grades (B3 and C) (P<0.05). By MIB-1 indices, we could tell how many cortical immature lymphocytes were occupied in TETs, however, grading could not be achieved.

A coronary artery aneurysm was first reported by Bougon in 1812, and was able to be diagnosed during life with advance of selective coronary arteriography. We have recently seen a 62-year-old woman who had intermittent anterior chest pain and dyspnea on exertion(NYHA functional class II) and diagnosed a coronary artery aneurysm by coronary arteriography. A saccular formed coronary artery aneurysm was located at left main coronary artery at the juction of the bifurcation of LAD and left circumflex artery and it's was 2cmx2cm and it's thickness of wall was 0.5cm. After the patency and consistency of coronary arteries were confirmed,resection of aneurysm with aneurysmorrhaphy was performed.

Renal oncocytoma is a uncommon benign tumor originating from the intercalated cells of the collecting duct, which occurs with an overall incidence of 3% to 7% among all renal tumors. Bilateral, multicentric renal oncocytoma is rare, especially in chronic renal failure. We report a case of 59-year-old woman with bilateral oncocytoma with renal failure. She presented nausea and vomiting for one month, and had no previous past medical history. Abdominal sonography and computed tomography revealed variable sized homogenous mass on both kidneys. Microscopic examination showed large polygonal cells with abundant eosinophilic and granular cytoplasm. Surrounding renal parenchyma revealed marked atrophy and sclerosis with a few intact glomeruli and tubules. We could exclude renal cell carcinoma because tumor cells were negative for CK7, CK20, vimentin, and Hale's colloidal iron staining, and did not show perinuclear halo and mitosis.

Mediastinal interfaces on a chest radiograph result from contact between mediastinal structures and the adjacent lung, while mediastinal lines result from contact between the two lungs across the midline. A variation of mediastinal interface is mediastinal stripe, a narrow band produced by contact of both sides of a mediastinal structure with the lungs. Alterations in mediastinal interfaces and lines may be due to variations in normal anatomy, or may reflect the presence of abnormalities within the mediastinum. Familiarity with the various normal mediastinal interfaces and lines, and the changes that occur with disease is important for the interpretation of the chest radiograph and in the diagnosis of mediastinal abnormalities. The purpose of this pictorial essay is to illustrate the most important normal and abnormal interfaces and lines and also to correlate radiographic and CT findings.

BACKGROUND: Scabies is an ectoparasite caused by the mite Sarcoptes scabiei var. hominis, an obligate human parasite. Although its incidence has been decreasing, it is not a rare dermatologic disease and is difficult to diagnosis. OBJECTIVE: To evaluate the clinical characteristics of scabies patients and find out etiologic factors in transmission. METHODS: Two hundred and ninety-five patients who were diagnosed with scabies at the Dermatologic Department, Myongji Hospital, Goyang city, Korea were enrolled. Medical records were evaluated in a retrospective manner. RESULTS: We studied 295 scabies patients who were diagnosed by the mineral oil test or skin biopsy. The mean age of the patients was 58.2 (male: 56.7/female: 61.2), and 74% of patients were over 60 years. There was seasonal variation in occurrence, and scabies was found to be most common in winter. The majority of suspected routes of infection were transmission through convalescent hospitals (38.1%) and caregivers (15.2%). Nosocomial infection and communal living were the major causes. 73.8% of scabies patients had underlying medical disease, such as hypertension (32.2%) and dementia (11.9%). CONCLUSION: Currently, scabies prevalence is still increasing in Goyang city, because of the increased number of convalescent hospitals.

Transmesenteric hernia is a rare cause of small bowel obstruction and is caused by congenital mesenteric defect or postoperative complication. At first because it is a rare type of internal hernia and also clinical simptoms can be nonspecific or intermittent, it is seldom diagnosed before laparotomy or autopsy. We report 3 cases, 1-, 2-, and 4-year-old children and found a small bowel gangrene caused by a congenital defect of mesentery. We describe autopsy findings, clinical simptoms and clinical diagnosis.

BACKGROUND/OBJECTIVES: Food insecurity has been suggested as being negatively associated with healthy behaviors and health status. This study was performed to identify the associations between food insecurity and healthy behaviors among Korean adults. SUBJECTS/METHODS: The data used were the 2011 Community Health Survey, cross-sectional representative samples of 253 communities in Korea. Food insecurity was defined as when participants reported that their family sometimes or often did not get enough food to eat in the past year. Healthy behaviors were considered as non-smoking, non-high risk drinking, participation in physical activities, eating a regular breakfast, and maintaining a normal weight. Multiple logistic regression and multinomial logistic regression analyses were used to identify the association between food insecurity and healthy behaviors. RESULTS: The prevalence of food insecurity was 4.4% (men 3.9%, women 4.9%). Men with food insecurity had lower odds ratios (ORs) for non-smoking, 0.75 (95% CI: 0.68-0.82), participation in physical activities, 0.82 (95% CI: 0.76-0.90), and eating a regular breakfast, 0.66 (95% CI: 0.59-0.74), whereas they had a higher OR for maintaining a normal weight, 1.19 (95% CI: 1.09-1.30), than men with food security. Women with food insecurity had lower ORs for non-smoking, 0.77 (95% CI: 0.66-0.89), and eating a regular breakfast, 0.79 (95% CI: 0.72-0.88). For men, ORs for obesity were 0.78 (95% CI: 0.70-0.87) for overweight and 0.56 (95% CI: 0.39-0.82) for mild obesity. For women, the OR for moderate obesity was 2.04 (95% CI: 1.14-3.63) as compared with normal weight. CONCLUSIONS: Food insecurity has a different impact on healthy behaviors. Provision of coping strategies for food insecurity might be critical to improve healthy behaviors among the population.

Cyanidin-3β-D-glycoside (C3G), which is widely distributed in herbal medicines and functional foods, exhibits anti-inflammatory, anti-oxidant, and anti-scratching behavioral effects. Orally administered C3G is metabolized to protocatechuic acid (PA) by gut microbiota. Therefore, we compared the anti-colitic effect of C3G to that of PA in mice with 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis. Orally administered C3G and PA preventively and curatively ameliorated TNBS-induced colitis parameters, including macroscopic colitis score, colon shortening, and increase of myeloperoxidase activity. Treatment with C3G or PA also inhibited the expression of cyclooxygenase-2, inducible NO synthatase, IL-1β, IL-6, and TNF-α and the activation of NF-κB in the colon of mice with TNBS-induced colitis. Furthermore, these also inhibited lipopolysaccharide-induced NF-κB activation and TNF-α expression in peritoneal macrophages. The anti-colitic effect of PA was more effective than C3G. Orally administered PA more potently attenuate colitis than C3G by inhibiting NF-κB activation and the anti-colitic efficacy of C3G may be dependent on the biotransformation of C3G to PA by gut microbiota.
