A case of contact dermatitis due to herb onintment is described in a 24 year-old female patient. After topical application of herb ointment, she developed erythematous papules and plaques on the face and neck. Patch test revealed positive reactions to ammoniated mercury, thimerosal, and the herb ointment. Energy-dispersive X-ray microanalysis of the herb ointment showed a striking peak for mercury.

The purpose of this study is to describe the magnetic resonance imaging (MR) findings of metastatic brain tumors with emphasis on the signal intensities of the lesion on MR. Thirty four patients with intracranial metastases were studies with MR imaging. The diagnosis was established on the basis of either brain biopsy or combination of brain MR findings and the presence of primary tumors. The primary tumors include lung cancer (n=18), breast cancer (n=3), stomach cancer (n=3), rectal cancer (n=1), renal cell carcinoma (n=1), hepatocellular carcinoma(n=1), ovarian cancer (n=1), thyroid cancer (n=1), melanoma (n=1) and unknown primary sites (n=4). The parenchymal lesions were solitary in 35% (12/34) and multiple in 65% (22/34). The size of the lesions was variable, ranging from several millimeters to 5cm in diameter. The corticomedullar junction of the cerebral heispheres was the most common location of the lesions (68%). The signal intensity of solid portion of the lesions was usually either isointense (44%) or hypointense (29%) on T1-weighted images, whereas it appeared in isointense (47%), hypointense (8%) or hyperintense (11%) on proton density-weighted or T2-weighted images. The remaining cases showed mixed signal intensities. The enhancement patterns were variable including nodular (<1cm) (6%), homogenous (19%), heterogeneous (10%), ring-like enhancement (22%) or mixed pattern(43%). The size of surrounding edema was larger than the tumor diameter in 76%. In conclusion, although there are no specific MR findings of intracranial metastasis except multiplicity, intracranial metastasis should be included in differential diagnosis with high priority, when a solitary mass showing isointensity on boty T1-and T2-weighted images with massive surrounding edema, especially in the corticomedullary junction of the cerebral hemispheres is encountered.

We observed the neonatal skin to investigate the incidence and clinical features of birthrnarks. We examined 1791 newborn babies admitted in the nursery of Kangnam Sacred Heart Hospital from July 1987 to July 1989. The results were summarized as follows. 1. Mongolian spots were observed in 1435 neonates (80.1%), occurring most frequently on the lumbosacral area. 2. Salmon patches were observed in 416 neonates (23.2%), the nape of neck being the most common site. 3. Pigmented lesions were observed in 20 neonates (1.1%). 4. Portwine stains were observed in 15 neonates (0.8%). 5. Epidermal nevi were observed in 4 neonates (0.2%) and nevus sebaceus developed in one baby.

Dermatofibrosarcoma protuberans (Hoffmann, 1925) is an uncommon, locally malignant fibroblastic tumor of the skin, which is characterized by infrequent metastasis and marked tendency of local recurrence after excision. Usual clinical lesion of dermatofibrosarcoma protuberans is a firm, raised, multinodular, tender tumor, which is fixed to the skin above, but movable over underlying tissues. Histopa,thologically, this tumor shows the characteristic cartwheel patterns, with the fibroblasts arranged radially about a small central hub of fibrous tissue. The authors report a case of recurred dermatofibrosarcoma protuberans, developed on the left arm of a forty-year old woman. There was no evidence of metastasis.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin. Most lesions of cutaneous angiosarcoma occur over the face and scalp. We experienced a case of angiosarcoma of the scalp in a 63-year-old man. Multiple pea-sized erythematous papules and nodules developed on the forehead 6 months ago. Thereafter, the lesions have extended to make violaceous, compressible and hemorrhagic plaques. On histologic examination, there were irregular, often anastomosing vascular channels lined by the atypical endothelial cells in the dermis.

The study was performed to measure and compare the peripheral blood T cell and T subsets in normal controls and psoriatic patients. Thirty-two normal controls and fift:en psoriatic patients were subjected to the study and the percentages and the rati vs of peripheral blood T cell and T subsets were measured. The results were as follows: 1. Mean percentages of peripheral blood lymphocytes reactive with OKT3 monoclonal antibody in psoriatic patients were 72. 8+-8. 2%, They decreased significantl) as compared with these in control group(76, 6- i-4. 7%). Mc an percentages of peripheral blood lymphocytes reactive with OKT4 monoclonal antibody in psoriatic patients were 47. 3+6, 7p;. They increased as compared with these in control group(46. 5+-3. 9p;), but the increase was insignificant. 3. Mean percentages of peripheral blood lymphocytes reactive with OKT8 monoclonal antibody in psoriatic patients were 27. 2+5. 5g, They decreased significantly as compared with these in control group(30, 6- l-4. 3%) 4. Mean ratios of lymphocytes reactive with OKT4 monoclonal antibody to these reactive with OKT8 monoclonal antibody in psoriatic patients were 1.8+- 0. 48 They increased significantly as compared with these in control group(1. 6+ 0.34).

We compared radiologically two groups of total hip prostheses, 36 porous-coated and 51 hydroxyapatite-coated, which had been implanted in 87 hips of 73 patients with avascular necrosis of the femoral head. Radiographs were taken at postoperative 1 year and 2 year, and used to compare various radiological parameters between the two groups. For the acetabular side radioluscent line and osteolysis were evaluated, and for the femoral side radioluscent line, osteolysis, stress shielding. endosteal new bone formation, subsidence and cortical hypertrophy were evaluated; their location was identified according to the zones described by DeLee and Charnley for the acetabulum and according to those described by Gruen et al for the femur. In both groups there was no subsidence. In terms of osteolysis, stress shielding and cortical hyper-trophy there was no significant difference between the two groups throughout the period. Radioluscent line in the acetabulum was more common around the porous-coated cup, but was focal and not progressive. The rate of radioluscent line in the femur was a little higher around hydroxyapatite-coated stem especially in zone 5. Endosteal new bone formation was excellent in both groups, but was more extensive around hydroxyapatite-coated stem. This study suggests that hydroxyapatite coating play a certain role in terms of bony ingrowth.

Subclinical hyperthyroidism and subclinical hypothyroidism are characterized by abnormal thyroid stimulating hormone (TSH) with normal free thyroxine. Subclinical thyroid diseases, to date, have received less attention compared with other thyroid diseases since they are asymptomatic. This study aimed to verify the association between subclinical thyroid diseases and cardiovascular diseases (CVDs) risk score in the Korean population. This was a population-based cohort study using data collected from 3,722 subjects (aged ≥ 30 years) during the 6th Korea National Health and Nutrition Examination Survey (KNHANES VI; 2013–2015). Gender-specific Framingham risk scores were calculated to identify the association between subclinical thyroid diseases and 10-year CVD risk score. Complex survey, with consideration of sampling weight, was analyzed using generalized linear models after stratification by gender. The TSH reference range was between 0.61 and 6.91 mIU/L in this study. TSH showed a positive association with the 10-year CVD risk score only in the female population (P = 0.001). There were significant differences in the least squares means of 10-year CVD risk score by the effect of subclinical hypothyroidism compared with euthyroidism (normal group) in females, after adjusting for body mass index, white blood cell, and urine iodine (P = 0.006 and Bonferroni corrected P = 0.012). In conclusion, subclinical hypothyroidism is associated with increased 10-year CVD risk score in the female Korean population aged 30 years or more. Therefore, we recommend to clinically checkup major CVD risk factors in female patients with subclinical hypothyroidism aged 30 years or more.
