The ligamentum nuchae is a midline structure extending from the occiput to the spinous process of the 7th cervical vertebra. Radio-opaque formations in the soft tissues behind the processes of the cervical spine has been known to radiologists since Barsony's description in 1929. It may actually be a normal sesamoid, or it may have developed as a result of previous trauma. But this remains hypothetical in that histological endochondral ossification sequence has not yet been demonstrated. These are generally asymptomatic and of clinical significance only in so far as they may be confused with fracture or tumors. Two patients who had clinical symptoms with or without previous trauma visited and they were relieved of their clinical symptoms by surgical excision. Then, we report on two unusual cases which were symptomatic.

Cortex mori (Morus alba L.: Sangbaikpi), the root bark of mulberry tree, has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. Previous studies have demonstrated that the phenolic extract of Cortex mori have hypotensive, hypoglycemic, antifungal, antiviral, antiinflammatory, and anticancer effects, and the hot water extract from Cortex mori has inhibitory effects on compound 48/80- induced mast cell degranulation and histamine release from rat peritoneal mast cells (RPMCs). This study was perforrned to investigate the effects of polysaccharide fraction from Cortex mori (PFCM) on compound 48/80-induced degranulation, histamine release, calcium influx, changes of intracellular cAMP and cGMP level, and morphological changes of RPMCs. The results were summarized as follows. 1) Compound 48/80-induced cytomorphological changes such as swelling, degranulation, intracellular vacuoles, and interrupted cell boundary were significantly inhibited by pretreatment with either hot water or polysaccaride fractions frorn Cortex mori (PFCM), 2) the compound 48/80-induced histamine release from RPMCs pretreated with PFCM was significantly inhibited, compared to that of control without PFCM pretreatment, 3) the PFCM inhibited remarkably the compound 48/80-induced calcium influx into the RPMCs, 4) the PFCM increased significantly the intracellular cAMP levels and decreased the intracellular cGMP levels of RPMCs, compared to those of normal control, and 5) the compound 48/80-induced cAMP levels of RPMCs pretreated with PFCM were significantly increased, compared to those of positive control without PFCM, and the compound 48/80-induced cGMP levels of RPMCs pretreated with PFCM were remarkably decreased, compared to those of positive control without PFCM. From the above results, it is suggested that PFCM have an activity to inhibit the compound 48/80-induced mast cell activation.

Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.

Thanatophoric dysplasia is the most common lethal congenital chondrodysplasia with characteristic features of narrow thorax, short rib, severe platyspondyly, short bowed limbs and skull deformity, etc. It is not a hereditary disorder and there is usually no family history of dysplasia. We experienced a case of thanatophoric dysplasia at 38 weeks of gestation with antenatal sonographic and abdominal radiographic findings of small thorax, short bowed extremities with surrounding thickened soft tissues and marked platyspondyly. Soon atter delivery, the baby died and post-mortem radiographs showed the characteristic findings of thanatophoric dysplasia.

BACKGROUND: Discrepancies exist in the existing researches regarding the association between social capital and self-efficacy, and most of these researches have been done in developed countries. The aims of this study were to assess the independent association between individual social capital and self-efficacy and to assess the associations between individual social capital, self-efficacy and self-rated health. METHODS: Data were obtained from the Gyeongnam health survey (6,500 persons) conducted in 2008. A self-administered questionnaire was additionally administered to gather information on demographic variables, health behaviors, chronic diseases, self-efficacy, social capital, and self-rated health status. Total study population was 3,843 as those with chronic diseases were excluded. RESULTS: In males, trust was positively associated with confidence and preference to task difficulty, and participation was negatively associated with confidence and positively associated with regulation and preference to task difficulty. In females, trust was positively associated with confidence and preference to task difficulty and negatively associated with regulation. Participation was positively associated with preference to task difficulty. In males, the odds for self-rated health status was better for persons with confidence (95% confidence interval, CI 1.088-1.705), trust (95% CI 1.172-1.821) and participation (95% CI 1.268-2.117). In females, the odds for self-rated health status was better for those with confidence (95% CI 1.250-1.803), preference of task difficulty (95% CI 1.019-1.683) and participation (95% CI 1.024-1.555). CONCLUSIONS: High social capital measured at an individual level may promote self-efficacy and health status.

To evaluate the clinical and histopathological significance of the proliferative activity in neoplastic and non-neoplastic thyroid lesions, we analyzed the mitotic count and the proliferating cell nuclear antigen labeling index (PCNA-LI) by immunohistochemistry as the proliferation- related markers. In this study included were surgically removed normal thyroid tissue (27 cases), adenomatous goiter (15 cases), Hashimoto's thyroiditis (5 cases), follicular adenoma (13 cases), follicular carcinoma (7 cases), papillary carcinoma (44 cases), poorly differentiated carcinoma (2 cases) and undifferentiated carcinoma (3 cases). The median PCNA-LI was 0 in normal thyroid tissue, 0.5 in adenomatous goiter, 6.2 in Hashimoto's thyroiditis, 1.2 in follicular adenoma, 4.8 in follicular carcinoma, 8.5 in papillary carcinoma, 60.8 in poorly differentiated carcinoma, and 55.2 in undifferentiated carcinoma (p=0.0001). Although PCNA-LI was exceptionally high in Hashimoto's thyroiditis, it was suggested that PCNA-LI could be used as a marker differentiating benign lesions from malignant neoplasm. Also, it could differentiate follicular adenoma from follicular carcinoma. Except clinical stage (p=0.0397), PCNA-LI was not related with sex, size, histologic subtype, and lymph node metastasis in papillary carcinoma. The presence of mitosis differentiated the neoplastic thyroid lesions from the non-neoplastic lesions (p<0.05), however, it could not divide benign and malignant neoplasm. These results suggest that an evaluation of the proliferative activity can help to differentiate the thyroid lesions. In addition, there was no significant correlation between the value of PCNA-LI and the presence of mitosis. It can be recommended to evaluate both the mitotic count and the PCNA-LI for determining the proliferative activity of the thyroid lesions.

We report a case of dedifferentiated liposarcoma of retroperitoneum as a recurrent form in a 41 year old male. The patient received a extirpation for retroperitoneal mass and diagnosed as myxoid liosarcoma 4 years ago. The patient experienced 3 recurrences over a period of 4 years and diagnosed as myxoid liposarcoma in the second, third recurrence also. Histologically, the mass was composed of several clearly distinct elements : well differentiated liposarcoma, myxoid liposarcoma, myxoid malignant fibrous histiocytoma, poorly differntiated sarcoma, and fibrosarcoma. Immunohistochemically, S-100 protein was expressed in the area of spindle cell sarcoma, well differentiated liposarcoma, and malignant fibrous histiocytoma but alpha-1-antichymotrypsin was only expressed in the area of myxoid malignant fibrous histiocytoma.

The vitreous changes in 183 eyes of 148 patients with vitreous floaters were evaluated biomicroscopically using the Goldmann fundus contact lenses. The cases with retinal detachment were excluded from this study. Vitreous degeneration was responsible in all eyes with vitreous floater, and posterior vitreous detachment(PVD) was found in 87% of the eyes. In those eyes the most common cause of opacity were prepapillary ring(139 eyes). There were no significant difference in prevalence rate between male and female or between right and left eye with PVD. However the incidence was increased at the age of 50 or more. A strong statistical relationship was present between early onset and male or myopic eyes with minus 3 diopters or more. The eyes with sudden onset of floaters were frequently associated with retinal breaks. The study revealed that the complications of PVD may be encountered: retinal breaks, vitreous hemorrhage, photopsia, and cystoid macular edema. The complications were common in male.

Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu disease is an autosomal dominant disorder characterized by repeated episodes of bleeding. Multiple telangiectases consisting of thin-walled, dilated vascular channels with arteriovenous communication may involve, for example, mucocutaneous tissue, the gastrointestinal tract, and the liver, lung, and brain. We report the imaging findings of two cases of HHT involving arteriovenous malformation of both the lungs and liver, a rare condition. Chest radiography revealed a round mass, while helical CT showed a feeding artery and draining vein with arteriovenous malformation in the lung. Color Doppler sonography revealed an enlarged and tortuous hepatic artery with high systolic velocity. CT demonstrated an enlarged hepatic artery, arteriovenous shunt, and early draining hepatic vein in the liver. Celiac angiography showed arteriovenous malformation.
