We report a case of solitary congenital calcified nodule of the ear in a 1-year-old female. The lesion was a 2 X 2mm-sized, elevated, slightly erythematous and whitish-centered nodule located since birth on the superior helical rim of her left ear. Histopathological findings fram the totally excised lesion showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination. Surrounding the calcium deposits, lymphohistiocytic infiltrations were present.

Multiple biliary papillomatosis involves an epithelial field change of the intrahepatic and extrahepatic portions of the biliary tree. Pathologically it is benign, occasionally with dysplasia, but the clinical behavior is regarded as having a low-grade malignant potential. Such malignancy is rare but the prognosis is poor if it is impossible to remove the tumor completely. Here, we report one case of multiple biliary papillomatosis in the biliary tree.

Isolated aneurysm of the common iliac artery that is secondary to medial degeneration (MD) is a very rare clinical entity. MD is an important histological abnormality that is commonly seen in the annuloaortic ectasia with Marfan syndrome. This abnormality is also observed in congenital aortic disease, atherosclerosis, and aging. This aortic disease develops as the consequences of disruption of the medial elastic layers in association with loss of vascular smooth muscle cells and the accumulation of proteoglycans. An iliac aneurysm greater than 3 cm in diameter should be treated. The treatment options include open surgical replacement with prosthetic graft or endovascular stent grafting. We experienced one case of the isolated common iliac artery aneurysm in a 60 year-old female patient. Her chief complaint was a pulsatile painful mass in the left lower quadrant of the abdomen that she had suffered with for 5 days. She was treated by performing aorto-left external iliac artery bypass with a Dacron graft (10 mm in diameter). The result was excellent. We report here on a case of a isolated common iliac artery aneurysm that was caused by MD, and we include a review of the relevant literature.

BACKGROUND: Obstructive sleep apnea (OSA) contributes to the development of cardiovascular diseases. The aim of this study is to analyze the association between OSA and cardiovascular diseases in adult. METHODS: We recruited 718 consecutive subjects (611 male, 44.8+/-12.7 years old) diagnosed as OSA based on overnight polysomnography. The prevalence of hypertension, diabetes mellitus, myocardial infarction and stroke was defined and compared with that in general adult population (the Third Korea National Health and Nutritional Examination Survey, KNHANES III 2005). Correlation between the prevalence and OSA severity was analyzed after adjusting age, sex, body mass index, smoking, and alcohol consumption. RESULTS: Prevalence of vascular diseases was higher in OSA than general population. Prevalence of hypertension was 39.0% (13.0% from KNHANES III), diabetes 8.2% (5.2%), myocardial infarction 3.0% (0.6%) and stroke 7.2% (1.6%). Apnea-hypopnea index as the marker of OSA severity significantly correlated with hypertension (p=0.01). CONCLUSIONS: Cardiovascular diseases were more prevalent in OSA. Prevalence of hypertension increased proportionally to OSA severity.

PURPOSE: Although numerous etiological models of premenstrual syndrome(PMS) such as the biochemical, hormonal, psychosocial models have been proposed, there is no consistent conclusion. Especially, in psychosocial model, state-dependent changes in the perception of stressors according to menstrual cycle phases was suggested for PMS. In this study, we investigated relationship between menstrual cycle and daily minor stressors in young women, and vulnerability to minor stressors in young women with PMS. METHODS: 46 female college students completed modified daily rating form(DRF) of premenstrual symptoms which based on DSM-IV criteria for PMDD, and daily stress inventory(DSI) during at least one menstrual cycle. If the mean score of at least one DRF item during premenstrual phase were more than 3 on 6 point scale and 30% increase in symptom severity during premenstrual phase compared with during postmenstrual phase, they were referred as PMS group(N=20), and the others as non-PMS group(N=26). The event, impact, and impact/event ratio scores of DSI were compared in two groups. Data were analyzed by analysis of variance with repeated measure ANOVA. And post hoc simple; repeated contrast test were performed when indicated by significant repeated measure ANOVA. RESULTS: In all subjects, the event and the impact scores in premenstrual and menstrual phases were significantly higher than in postmenstrual phase. Among the DSI categories, the impact scores of interpersonal problem and cognitive stressors in premenstrual and menstrual phases were significantly higher than in postmenstrual phase. In PMS group, there was a significant difference between premenstrual and postmenstrual phase in the impact score but not in the event score, and the event and the impact scores were significantly increased in menstrual phase than postmenstrual phase. In non-PMS group, the event and the impact scores in premenstrual and menstrual phases were significantly higher than in postmenstrual phase. There was no significant difference in the impact/event ratio scores in both groups. Between the PMS and non-PMS group, there was significant difference in the impact/event ratio scores in premenstrual phase, but not in the event score and the impact scores at any phase. CONCLUSION: Young women may experience more daily minor stressors and may be impacted more severely in premenstrual and menstrual phases than in postmenstrual phase. In premenstrual phase, the young women with PMS are likely to have more vulnerability to daily minor stressors than controls. Further studies using larger sample size with varied age are required.

A pyogeinc granuloma, also known as a lobular capillary hemangioma, is a benign vascular tumor of the skin and mucous membranes, which is common in infants and children. It usually presents as a rapidly evolving solitary, sessile, or polypoid vascular nodule. An intravenous pyogenic granuloma (IVPG) is a rare form of pyogenic granuloma, in which the whole lesion appears as a single polypoid mass projecting into the lumen of a vein. All reported cases of IVPG have been limited the head, neck, and upper extremity. We report a case of an intravenous pyogenic granuloma located within the iliac vein of a lower extremity.

Peliosis hepatis is an uncommon liver condition involving abnormal dilation of hepatic sinusoids, eventually leading to blood-filled cavities within the hepatic parenchyma. Although the pathogenesis is not understood fully, peliosis hepatis has usually been associated with the use of anabolic steroid therapy, oral contraceptives, various malignancies or tuberculosis. We report a case of 59-year-old patient with cholangiocarcinoma with peliosis hepatis. The patient was admitted for evaluation of abdominal pain and fever. Abdomen CT showed a round cytic and solid mass with peripheral duct dilatation in liver. Grossly, the spongy-like solid mass and cyst was noted. Microscopically, the solid mass was composed of tubular and solid adenocarcinoma in fibrotic stroma and a blood-filled cavity with dilated sinusoids was noted.

Gastrointestinal autonomic nerve tumors (GANT) are uncommon neoplasms of the gastrointestinal tract. The GANT is a specialized form of stromal neoplasm with the feature of myenteric plexus derivation. We report a patient with a GANT of the small intestine and liver metastasis. The patient was admitted for evaluation of hematochezia and a palpable abdominal mass. A CT of the abdomen showed an exophytic mass arising from the distal ileum and exhibiting deep ulceration and air-cavity formation, and a huge cystic mass in the right lobe of the liver. The gross appearance of a surgical specimen of the liver showed a huge cystic mass, containing liquified hemorrhagic fluid, with an irregular nodular peripheral portion. Its capsule was intact. An ileal mass, measuring 9x5 cm and arising from the submucosal layer, with deep ulceration was seen. Histological examination of the liver and the ileal mass revealed a malignant stromal tumor with neural differentiation on immunohistochemical staining.

Patients with Sjögren's syndrome usually suffer from teeth discoloration and attrition due to xerostomia. If the anterior teeth are badly worn, problems such as loss of anterior guidance, occlusal disharmony, and limited space for restoration may occur. However, ideal occlusion is obtained in both centric and eccentric relation by regaining the disocclusion of the posterior teeth through the anterior and lateral guidance using twin-stage method. In this case, rehabilitation was performed for a Sjögren's syndrome patient with maxillary and mandibular incisor's severe attrition and teeth discoloration by using twin-stage method.
