Congenital subglottic stenosis of the larynx is one of the most common cause of chronic airway obstruction im infancy and childhood. It is defined as narrowing of the space bounded inferiorly by the inferior margin of the cricoid cartilage amd superiorly by the insertion of the fibers of the conus elasticus into the true vocal cords. In case we experienced was a female full-term baby delivered by Cesarean section. The stenosis was believed by hypertrophy of stromal soft tissue and cricoid cartilage in the subglottic area. The lesion was associated with tracheoesophageal fistula of H1 type. A brief review of the literature was done.

Because neuroblastoma is predominantly a tumor of childhood, patholgists and clinicians tend to exclude it from differential diagnosis when the patient is an adult. The diagnosis of neuroblastoma by light microscopy can be difficult because of similarities between neuroblasts and cells of other round cell neoplasms. The fine structural features of neuroblastoma is distinctive and is valuable in its diagnosis. We present 2 cases of neuroblastoma and a case of ganglioneuroblastoma arising in adults with their ultrastructural findings.

Fibrous histiocytomas are characterized by a variable combination of cells with fibroblastic and histiocytic features. They exhibit a distinctive but inconstant cellular arrangement referred to as a storiform or cartwheel pattern. Considerable corfusion has enveloped these tumors as a result of their various terminology-fibrous histiocytoma, dermatofibroma, sclerosing hemangioma, fibroxanthoma, subepidermal nodular fibrosis, xanthogranuloma, giant cell tumor of tendon sheath. A histologically benign but locally infiltrating, 15 * 20cm sized, fibrous histiocytoma was found in the posterior aspect of left thigh of a 17-year-old man. The tumor was incompletely excised due to adhesion of the tumor mass to sciatic nerve and then radiation therpy was combined, Histogenesis and prognostic aspects of the tumor are discussed.

Five cases of intracranial lipoma diagnosed by MR are presented. MR imaging was performed on a 0.2T permanent unit using T1 weighted, proton density-weighted, and T2 weighted spin echo sequences. In two patients, gadolinium-enhanced T1 weighted image was also obtained. The lipomas were located dorsolaterally to the splenium of the corpus callosum (n=1), inferior to the splenium (n=2), in quadrigeminal plate(n=1) and in the presumed corpus callosum area in the case of agenesis of corpus call?um (n=1). The size and shape of the lipomas were variable. No contrast enhancement was seen in post contrast study. Sagittal T1 weighted image appeared to be the most useful imaging plane for the demonstration of the relationship between the lipoma ad the adjacent normal structures. The Homogenous signal intensity paralleling the fat signal and the characteristic location of the lesion are considered to be helpful in the differential diagnosis from dermoid cyst or teratoma.

This study was conducted to investigate the effect of sodium reduction education program of a public health center on the blood pressure, blood biochemical profile and sodium intake of hypertensive adults. The program continued for 16 weeks with an 8-week nutrition education and an 8-week follow-up to forty two subjects, 6 males and 36 females aged 46 to 80 years. Subjects received nutrition education including lectures, activities, cooking classes and nutrition counseling. Physical fitness, management of stress, and nutrition counseling were provided during the follow-up. The program was evaluated three times, before and after the nutrition education, and after the follow-up. Systolic blood pressure (p < 0.0001) and diastolic blood pressure (p < 0.001) were decreased after completion of the program. Body weight (p < 0.005), percent body fat (p < 0.005) and body mass index (p < 0.001) were decreased, too. There were no significant differences in blood glucose, HDL-cholesterol and triglycerides, while elevated levels of total cholesterol (p < 0.001) and LDL-cholesterol (p < 0.001) appeared after the program completion. Decreased intakes of vitamin A (p < 0.05), beta-carotene (p < 0.001) and sodium (p < 0.001) were observed. Consumption frequency of noodles, soups, stews, kimchi, fishes/shellfish, seasoned vegetables, and salted seafoods/pickles (p < 0.05~p < 0.001) were decreased, while that of all food groups were not changed during the follow-up. Total score of nutrition knowledge related to sodium intake and hypertension (p < 0.001), and that of dietary behavior associated with high sodium intakes were changed positively (p < 0.001) only during the nutrition education. This sodium reduction education program, including the follow-up study showed positive effects on the blood pressure, sodium intake, nutrition knowledge and dietary behavior of hypertensive adults.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

The particle size of suspended particulates was measured by a Andersen air sampler from Mar. 1982 to Feb. 1984 in a part of Seoul. It was concluded as follows: 1) The arithmetic concentration of suspended particulates was 147.8 microgram/m3 in Spring, 136.9 in Summer, 131.9 in Autumn and 158.1 in Winter respectively. 2) The cumulative distribution of suspended particulates size in logarithmic diagram showed similar to normal log distribution. 3) The atmospheric particulate matters showed a bimodal size distribution on the base of unit particle concentrations, which divided at approximately 2 micrometer in the diameter. 4) While the fine particulates less than 2.1 micrometer was 35.4-45.0%, the coarse particulates was 55.0-64.5%. 5) The higher the concentration of suspended particulates, the more increased the ratio of fine particulates. The higher the concentration of suspended particulates, the lower median size of suspended particulate as well. 6) The respirable dust particulates less than 4.7 micrometer was 52.2-62.9% in seasonal average through the 2 year samples. With the above result, air pollution concerned with public health could be evaluated and the control measures also are suggested.
