To estimate the prevalence of hypertension among the aged in urban area, the blood pressure was examined on the subjects of 565 men and 762 women of 65 years old and older among the residents of Nam-Ku and Soosung-Ku in Taegu between January and December, 1986. The mean systolic blood pressure was 136.0±25.01 mmHg in male and 133.0±24.56 mmHg in female. The mean diastolic blood pressure was 83.7±14.41 mmHg in male and 82.4±14.43mmHg in female. There was no significant differences between male and female in both mean systolic and diastolic blood pressure. According to WHO category, the prevalence of pure systolic hypertension (≥169/≤95 mmHg) was 7.8% in male and 6.8% in female. The prevalence of pure diastolic hypertension (≥160/≤95 mmHg) was 6.0% in male and 3.9% in female. The prevalence of both systolic and diastolic hypertension (≥160/≤95 mmHg) was 13.5% in male and 12.9% in female. According to Joint National Committee category, the percentage of normal blood pressure (/<90 mmHg) was 46.7% in male and 50.8% in female. The prevalence of mild hypertension (/90=104 mmHg) was 34.5% in male and 34.6% in female. The prevalence of moderate hypertension (/105=114 mmHg) was 5.1% in male and 2.5% in female. The prevalence of severe hypertension (/≥115 mmHg) was 2.3% in male and 2.5% in female. The prevalence of borderline isolated systolic hypertension (140-159/<90 mmHg) was 9.0% in male and 6.6% in female. The prevalence of isolated systolic hypertension (≥160/<90 mmHg) was 2.3% in male and 2.5% in female.

Benign hemangioma of the mediastinum is rare. This slowly growing tumor is described as well circumscribed, cystic, hemorrhagic tumor. Histologically it can be differentiated into capillary or cavernous form. We present a case of mediastinal hemangioma. A 20-year-old-man was presented with a slowly growing posterior mediastinal mass of 6 years duration, 8x6 cm in size. The mass was relatively well defined but focally invasive. Microscopically, it was differentiated into vessels of capillary, cavernous, and venous patterns. A solid cellular proliferation with inconspicuous capillary lumens was focally seen. The stroma between variable-sized vessels showed marked myxoid change associated with some smooth muscle bundles and adipose tissue. Ultrastructurally, areas of solid cellular proliferation showed formation of lumens. These lumens were lined by active endothelial cells showing plasmalemmal vesicles and Weibel-Palade bodies on the abluminal surface.

Renal dysplasia results from aberrant histogenesis in metanephric differentiation. It is characterized morphologically by abnormal organization and a persistence of primitive structures, such as cartilage, undifferentiated mesenchyme, and immature tubules. Six cases of renal dysplasia from five children and one adult are reviewed. Five patients were female and one patient was male. The chief complaint was urinary incontinence in four patients, dysuria in one patient, and the sixth patient suffered from vesicoureteral reflux. No evidence of family history of renal dysplasia in any patient was seen. According to Risdon's classification, three cases were hypoplastic dysplasia, one case was dysplasia in a duplex system, one case was dysplasia in a triplex system, and one case was dysplasia with vesicoureteral reflux. The ipsilateral ectopic ureteral orifice was identified in four patients, two of which drained into a Gartner's duct cyst, and the orifice was suggested in one patient. On histologic examination, all cases showed primitive ducts surrounded by concentrically arranged primitive mesenchyme. Nests of metaplastic cartilage were observed within the stroma in three of the six cases.

Primary role of ultrasound in patients with thyroid nodule is to determine the multiplicity and detect occult carcinoma. We analyzed US findings of 53 thyroid carcinomas with multiple nodular lesions from january 1988 to december 1991. The results were as follows: 1. 109 malignant nodules in 53 cases and 24 benign in 23 were comfirmed. 2. The nature of the masses were solid in 72 malignant nodules (74.2%), and complex in 25 (25.8%) of which 19 were predominantly solid. 3. The echo pattern of the solid and solid predominant masses were hypoechoic in 78 malignant nodules (80.4%), hyperechoic in 10 (10.3%), and isoechoic in 3 (9.3%) 4. Internal punctate calcifications within the masses were observed in 31 malignant nodules (31.9%). 5. Halo sign was present in 16 malignant nodules(16.5%). 6. The preoperative sonographic diagnosis of thyroid carcinoma was made in 39.4% of 53 cases with multiple nodules on US. In conclusion, the number, and halo formation of nodules were insignificant to differentiate the benign nodule from the malignant. The heterogeneous hypoechoic nodules with size greater than 4cm, multiple stippled calcifications, displacement of the trachea or other surrounding structures of combined lymph node enlargements seem to indicate the possibility of malignancy.
