BACKGROUND: To investigate the possibie difference, if any, between office blood pressure(BP) and home BP may be important in the diagnosis and treatment of hypersensive patients. This report deails the difference between the two BP's and the usefulness of digital electronic sphygmomanometer(DES) for self-monitoring of home BP. METHODS: The BP's of 14 patients with essential hypertension were measured with mercury sphygmomanometers at outpatient department by physician and with DES at home(twice a day) by the patients. Patients were followed up every 2 weeks for 4 weeks and previous 2 weeks' average home BP's were compared with the office BP's of each 2 weeks' end. RESULTS: There was a significant difference between office and home BP(both systolic and diastolic) ; office average BP(151/95mmHg) was higher than home average BP(136/86mmHg). CONCLUSION: Caution may be needed in the interpretation of office BP unless it is measured several times after adequate rest.

Trichophyton tonsurans is a major causative agent of tinea capitis in the United States, Canada, Mezico and other Latin American countries, but the infection of T.tonsurans has not been reported in Korea. We report a case of tinea capitis caused by T. tonsurans in a 15-year-old student wrestler. He had a 3*3cm sized non-inflammatory alopecia with black dots on the right occipital area of the scalp. The diagnosis was established by a hght microscopic examination of the affected hairs and by mycological studies from cultures. To our knowledge, this is the first case in which T. tonsurans has been isolated in Korea, It is likely that the student acquired the infection through contact with a foreign wrestler during interaational games and practice. We should be concerned about the potential of spread of this infection in our country.

We report a case of erythema elevatum ditinum in a 6-year-old girl. Th symmetrically distributed skin lesions consisted of elevated purplish annular plaques and nodules on the elbows, knees, ankles and buttocks, and some of the lesions showed vesicles, hemorrhagic crusts, and necroses. Biopsy specimens from the knee and ankle revealed typical leukocytoclastic vasculitis. Ve performed a Multites CMI, a test for delayed r.utaneous hypersensitivity, in which the patient showed positive reaction to streptococcal antigen(Lancefield group C). We tried oral prednisolone and dapsone seperately and could see a remarkable response to both drugs.

We report two cases of nonvenereal sclerosing lymphangitis of the penis in a 34-year old man and a 28-year-old man. This disorder is an uncommon condition characterized by asymptomatie, firm, cord-like lesion of unknown etiology. Histopathologic findings reveal hypertrophy and sclerosis of lymphatic vessel walls, and some cases show thrombus formation within dilated vessels. Both cases had typical clinical and histopathologic features. In case I, the lesion resolved spontaneously on several occasions for 10 years. Therefore we argue that some individual may be predisposed to develop the condition, perhaps because of anatomical variation.

Disorders of coagulation and uncontrollable bleeding are major problems during a major surgical operation. The correct diagnosis, appropriate treatment and preparation for abnormal coagulation and bleeding conditions with specific factors and blood products are procedure of utmost importance. Detailed history, physical examination and performance of appropriate laboratory tests including specific factor assay are essential for the diagnosis of an abnormal coagulation and bleeding problem. We have experienced a case of factor ll deficient patient who had surgery for a glioma of the forebrain. He had a past history of two episodes of massive bleeding during operation and showed a bleeding tendency after angiography for this last admission, but he didn't show any abnormal blood coagulation tests except for a factor ll deficiency. He had received Vitamine K 20 mg/day for 7days preoperatively. All laboratory coagulstion tests became normal and he had a surgical removal of a forebrain glioma uneventfully under general anesthesia. He received only 1 unit of fresh frozen plasma during operation and had an uneventful postoperative course.

Diffuse aspiration bronchiolitis is defined as a clinical entity characterized by a chronic inflammation of bronchioles caused by recurrent aspiration of foreign particles. Clinical symptoms are bronchorrhea, bronchospasm, and dyspnea, and chest radiographs show the presence of regional or disseminated srnall nodular shadows and hyperlucency. Chest CT should help in detecting diffuse nodular shadows of bronchiolitis. Pathologic findings of diffuse aspiration bronchiolitis are characterized by localization of chronic mural inflammation with foreign body reaction in bronchioles. Recurrence of small amounts of aspiration might play an important role in the pathogenesis of diffuse aspiration bronchiolitis. We report a case of diffuse aspiration bronchiolitis in a 4-month- old female infant who had recurrent aspiration due to dysphagia and presented with recurrent fever, dyspnea and wheezing. She showed typical radiologic and histologic findings compatible to diffuse aspiration bronchiolitis. She was improved with treatment of nasogastric tube feeding. We emphasize the importance of recognizing this disease entity and differentiating it from pulmonary diseases associated with bronchospasm. (J Korean Pediatr Soc 2000;43:842-845)

STATEMENT OF PROBLEM: Zirconia-based restorations have the common technical complication of delamination, or porcelain chipping, from the zirconia core. Thus the shear bond strength between the zirconia core and the veneering porcelain requires investigation in order to facilitate the material's clinical use. PURPOSE: The purpose of this study was to evaluate the bonding strength of the porcelain veneer to the zirconia core and to other various metal alloys (high noble metal alloy and base metal alloy). MATERIAL AND METHODS: 15 rectangular (4x4x9mm) specimens each of zirconia (Cercon), base metal alloy (Tillite), high noble metal alloy (Degudent H) were fabricated for the shear bond strength test. The veneering porcelain recommended by the manufacturer for each type of material was fired to the core in thickness of 3mm. After firing, the specimens were embedded in the PTFE mold, placed on a mounting jig, and subjected to shear force in a universal testing machine. Load was applied at a crosshead speed of 0.5mm/min until fracture. The average shear strength (MPa) was analyzed with the one-way ANOVA and the Tukey's test (alpha= .05). The fractured specimens were examined using SEM and EDX to determine the failure pattern. RESULTS: The mean shear strength (+/- SD) in MPa was 25.43 (+/- 3.12) in the zirconia group, 35.87 (+/- 4.23) in the base metal group, 38.00 (+/- 5.23) in the high noble metal group. The ANOVA showed a significant difference among groups, and the Tukey's test presented a significant difference between the zirconia group and the metal group. Microscopic examination showed that the failure primarily occurred near the interface with the residual veneering porcelain remaining on the core. CONCLUSION: There was a significant difference between the metal ceramic and zirconia ceramic group in shear bond strength. There was no significant difference between the base metal alloy and the high noble metal alloy.

We herein report a case a demodicidosis, which is extremely rare in early childhood, in a 19 month old boy. He had been admitted to the department of plastic surgery for 20 days because of burn on both legs. During admission, he hadn't had his face washed at all. He was referred to our department due to progressively appearing, multiple, pinhead sized, dry scaling, erythematous papules on the face of 13 days duration. KOH mounts from the scaly papules revealed numerous hair follicule mites. We treated him with topical application of 25% benzoy1 peroxide gel to see complete clearing of the lesions in 32 days. We think that prolonged ret.ention of sebum in the unwashed skin, such as in our case, may predispose to the poliferation of the hair follicule mites.
