BACKGROUND: Although the wet earwax has been known to be related with the incidence of tinea versicolor, very little has been revealed on how they are correlated with each other. The incidence of Malassezia furfur, the etiological organism of tinea versicolor, and its population densities as yearst and mycelial form in the different types of earwax, the dry and the wet, have not been studied. METHODS: The type of earwax in 65 patients with tinea versicolor were classified into 2 types, dry and wet, by its appearence and the subjective complaints of the patients. The dry and wet cerumens were obtained from 142 and 49 individulas without tinea versicolor respectively. The cerumens were stained with 10% Parker ink-KOH solution. The incidence and its population densities of yeast and mycelial M. furfur in the wet cerumens were compared with those in the dry cerumens according to a new grading method using bacterial index(BI) of lepra bacilli. RESULTS: 1. Dry and wet earwax were observed in 58.5%(38 cases) and 41.5%(27 cases) of 65 patients respectively. 2. The incidence of yeast M. furfur in the dry and wet cerumens were 100% and 63.3%(31 of 49 cases) respectively, and that of mycelial M. furfur, 28.2%(40 of 142 cases) and 32.7%(16 of 49 cases) respectively. 3. The population densities(from 3+ to 6+) of yeast M. furfur in the dry and wet cerumens were ob served in 93.0%(132 of 142 cases) and 49.0%(24 of 40 cases), and those(3+) of mycelial M. furfur, 21.1%(30 of 142 cases) and 24.5%(12 of 49 cases) respectively. CONCLUSION: The incidence(41.5%) of wet earwax in tinea versicolor patients is significantly higher than that(0.8%) in The Korean control group. The ratio between the incidence of mycelial M. furfur and that of yeast M. furfur in the wet cerumens is higher than in the dry cerumens, and the ratio of population densities in the wet cerumens is also higher. These observations suggest that the skin surface conditions of the wet earwax group may be more suitable for yeast-mycelial transformation of M. furfur than those of the dry earwax group. The comparison of chemical compositions of the skin surface between dry and wet earwax groups is needed to elucidate the correlation between tinea versicolor and the types of earwax in the future.

Desmoplastic small round cell tumor (DSRCT) is a rare neoplasm of young adults and it is characterized by polyphenotypic differentiation. We experienced a case of abdominal DSRCT that occurred in a 19-year-old female who presented with painful swelling of her right forearm. The tumor was cytokeratin-negative and it exhibited some tumor cells with intranuclear inclusions. Molecular demonstration of EWS-WT1 fusion transcripts is particularly useful to confirm the diagnosis of DSRCT without epithelial differentiation. We report here on a case of cytokeratin-negative DSRCT that showed an unusual feature of intranuclear inclusions.

Eczema herpeticum occurred in a patient with pemphigus foliaceus and esophageal cancer. The patient's initial skin lesions composed of large flaccid bullaes showed subcorneal bullae with typical acantholytic cells. Subsequent grouped small vesicles appeared widely on the erythematous base were diagnosed herpes simplex virus infection by Tzanck smear and histopathological findings. The patient died one week after the development of the widespread herpes virus infection.

The ankle is a complex, weight-bearing joint and has an important role in walking. The injuries to the ankle joint complex include not only injuries that cause disruption of the bony architecture of the ankle joint but often significant ligamentous and soft tissue components. The literature on ankle fractures have divergence of opinion on treatment. However, the method used to obtain a good end result of treatment is a matter of differing opinion. One hundred and seventy six patients with one hundred and eighty cases of ankle fractures treated at Severance Hospital, Yonsei University College of Medicine from Jan. 1971 to Dec. 1980 were analized in clinical and radiological aspect. The results obtained from this study were as followings: 1. Among the 176 patients, male was 126 patients and female 50 patients (M:F=2.5:1). The average age was 29. 2. Of the 180 cases, the main cause of fractures was traffic accident, 74 cases (41.1%) and the other causes were falling from a height (16.1%), slipping down (15.0%) and sports injuries (12.8%) in order. 3. The fractures were almost closed fractures (84.4%). 4. According to the classification of Lague-Mansen, the pronation-external rotation type (40.6%) was the commonest type. 5. One hundred and twelve cases (62.2%) were treated by open reduction and 68 cases (37.8%) by closed reduction. 6. The average period of the cast immoblization after the open reduction was 8 weeks but the closed reduction was 10 weeks. 7. According to clinical and radioiogical assessment of the result of the treatment, the open reduction was better than closed reduction. 8. The fibular fracture involving lateral malleolus and the diastasis of the distal tibiofibular syndesmosis were very important in ankle stability and were treated by internal fixation for accurate anatomical reduction.

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.

PURPOSE: This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS: Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test. RESULTS: The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). CONCLUSION: The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.

Basaloid follicular hamartoma (BFH) is a benign adnexal tumor with a wide spectrum of clinical appearance and is characterized histologically by the presence of branching cords and thin strands of undifferentiated anasomosing, basaloid proliferations that are embedded in a fibrous stroma. It has been often misdiagnosed and treated as basal cell carcinoma. We report a 57-year-old woman with BFH on the face which is similar to basal cell carcinorna clinically that turned out to be a solitary BFH histologically. There has been no recurrence during one year of follow up after excisional biopsy.

A 12-year-old boy showed a slatecolored scaly patch on h; ight face for 2 months. Histopathologic findings showed basal vacuolations and dermal me arphages with only scanty lymphoid cells in the fat tissue layer. Besides the facial lesion, lesions of edematous localized erythema were noted on his right if and left buttock with similar mi rocopical findings. 6 months later the facial lesion was aggravated like a cellulitis, of which thc bevpsy findings were consistent with mycosis fungoides. The patient received chemotherapy aftei the diagonsis for one month before his termination. Because of the rarity of mycosis fungoides in childhood age and its un common cutaneous lesions, the case is reported.

Porencephaly is relatively rare condition defined by an defect or a defect or cavity in the cerebrum owing to a developmental malformation or to a destructive lesion. Fory-five porencephaly patients diagnosed by Brain CT were clinically analyzed and the following results were obtained. 1) By the age group presenting initial symptoms, the peak incidence was from 1 month to below 3 years old. 2) In initial symptoms, seizure, spastic weakness, headache were showed in order of frequency. But 7 cases (15.5%) were asymptomatic. 3) The latency of diagnosis after presenting initial symptoms from the symptom onset time to 10 years. 4) The subsequent symptoms were as follows: spastic weakness, speech disturbance, gait disturbance, mental retardation, sensory loss and seizure showed independently or combined. 5) As etiologic factor, 21 cases (46.7%) were congenital, 16 cases (35.5%) were post-traumatic or post-operative and 8 cases (17.8%) were perinatal. 6) The prognosis was seen various from mild to severe. Out of 45 cases, 29 cases (64.4%) were no complications. But the prognosis in patients with post-traumatic or postoperative etiological factors was poor. With the advent of brain CT and the resultant capability of detecting structural defect and cerebral lesions responsible for epilepsy or focal neurologic signs, porencephaly was seen to be readily recongizable by CT examination. Since porencephaly is a significant contributor to the spectrum of CNS lesion and benign condition, ist recognition is important in determining prognosis and therapy.
