The basic principles of the applanation tonometer and Schiotz tonometer were briefly discribed. The major improvement in the applanation tonometry is in the fact that the scleral rigidity plays no important role in the determination of the intra-ocular pressure. We have measured the intra-ocular pressure with both types of tonometer, the applanation tonometry being the first, followed by Schiotz reading with 5.5 g weight. In normal eyes, both readings gave almost identical results. In glaucomatous eyes, recently operated cataract eyes and eyes with retinal detachment successfully operated showed wide discrepancies between the values of two methods. The pressure readings with Schiotz tonometer were moderately lower than that with applanation tonometer, and this might cause erroneous conclusion regarding the real status of the intra-ocular pressure in such eyes. Advantages and disadvantages of the applanation tonometery were discussed.

The authors eneountered a 39 years old male patient with extensive Fordyce's disease involving the upper lip and buccal mucous mernbrane. The skin lestens were small, discrete and grouped yellowish white papules of about 10 years duration. Diagnosis was made by the characteristic clinical and histopatholqgiC findings.

In spite of vigorous efforts to enhance appropriateness of blood usage in surgery, it is recognized that there are still not a few overuse and misuse of blood products in Korean hospitals. To assure appropriate use of blood, continuous monitoring and controlfling blood orders, particularly for surgical operations, should be implemented. The indicator of 'ratio of crossmatching to transfusion' (C/T ratio) has been focalized on in this regard. The authors investigated C/T ratio for eight hospitals, evenly distributed in their geographical location as well as size. Only elective surgeries operated from March 1 to May 31, 1995 were included for analysis. Standardized survey format was distributed, and retrospective reviews of medical records were performed by volunteer surveyors from each hospital after two sessions of pre- survey education. The results were as follows. Average C/T ratio, for all hospitals and all surgeries, was 1.76. Differences in C/T ratio by sex, months, clinical departments, blood components were not significant. However, the ratio showed increasing tendency with ages. The C/T ratio on the average was not higher, compared with the recommended guideline. However, due to study' s limitations ini standardization of survey method and verification of data, we could not conclude that current status of appropriateness of blood use is satisfactory. In addition, to pervasively use the C/T ratio as a quality indicator for blood use management, supplementary measures, such as standardization of data, should be adopted.

Primary malignant parovarian epithelial tumors are extremely rare, with only 56 cases previously reported in the world literature. Most parovarian epithelial tumors are of paramesonephric (Mullerian) origin. In this article, we report the first case in the Korean literature of papillary serous cystadenoma of borderline malignancy from paramesonephric parovarian cyst. This case presented here is of particular interest since this neoplasm is rare. A 48-year-old female underwent a hysterectomy with bilateral adnexectomy and pelvic lymph node dissection for a cystic tumor of the right parovarian area. The tumor, measuring 13 cm in diameter, was apart from the ovaries, fallopian tubes and uterus. The cyst wall had well-developed smooth muscle layers. The cyst was lined with mildly atypical ciliated and non-ciliated low columnar cells compatible with those of paramesonephric origin. From the inner surface of the cyst several cauliflower-like structures projected into the lumen. They were of a predominantly papillary architecture covered by atypical epithelial cells with piling-up and occasional glandular growth. No destructive stromal invasion was identified.

We observed three patients who showed widespread macular ashy-colored eruptions. They fit clinically and histopathologically with the typical erythema dyschromicum perstans (ashy dermatosis). Erythoma dyschromicum perstans is a peculiar pigmented condition of unknown etiology characterized by persistent ashy-gray colored macule, refractory to any modality. All of them have similar skin lesions which are multiple, variable sized oval-shaped, ash-colored macular eruption on the trunk and extremities. Histologic findings of 2 patients reveal the characteristic feature of focal hydropic degeneration of the basal cell layer of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium, however, merely pigmentary incontinence into the corium in 1 patient. Literatures are briefly reviewed.
