We report a case of malignant histiocytosis which began with intermittent fever and scaly skin lesions. A 3-year-old girl presented with erythematous scaly papules on the face and the trunk, and high fever for 3 months. The cutaneous lesions consisted of widespread coin-sized erythematous scaly papules with marginal brownish pigmentation. She was anemic and thrombocytopenic and had impairment of the liver function. Histopathologic study of the skin lesions showed non-specfic findings except for hyperkeratosis. However, bone marrow examination revealed an increased number of histiocytes, mostly immature with active phagocytosis of erythroid cells, myeloid cells, and platelets. She was diagnosed as having malignant histiocytosis and treated with cyclophosphamide and vincristine. She died the next day after the treatment had begun.

Superficial gastritis has been classified as a type of chronic gastritis, since a report of Schindler in GASTRLTIS, 1947. Howev~er, Benedict reported that superficial gastritis is only acute gastritis or shows normal mucosa histologically. The com mon endopical findings of chronic superficial gastritis were adherent mucus, edema, redness. The common redness which were encounterd are patchy redness and comb-like redness(Kammrotung). We studied the relationship between the redness of superficial gastritis and acute inflammatory changes histologically. Each case of superfieial gastritis was biopsied to redening and non-redening mucosa respectively. We collected 24 cases with 48 biopsy specimens. The results are as follows: Acute inflammatory changes were found only one case in redness and none in non-redness groups. There was no difference in acute inflammatory changes in two groups. The degree of mucosal atrophy were 62.5%, 66.7% in normal mucosa, 12.5%, 16.7~% in mild atrophy, 25%, 12.5% in moderate atrophy, 0%, 4.l% in severe atrophy with respect to redness and non-redness mucosa respectively. There was no difference in degree of mucosal atrophy in two groups. Mucosal atrophies were higher in older ages above 41 years old than below 40 and with increasing age, there was increasing tendency of mucosal atrophy. In conclusion, There was no relationships between mucosal redness and acute in flammatory changes histologically and also between mucosal redness and degree of atrophy.

This study was designed to evaluate the expression of growth factor in periodontal tissue during the experimental movement of rat incisors by LSAB(Labelled streptavidine Biotin) immunohistochemical staining for EGF(Epidermal growth factor). 23 Sprague-Dawley rats were divided into a control group(3rats) and experimental groups(20rats), where a force(75g) from helical springs across the maxillary incisors was applied. Experimental groups were sacrificed at 12 hours, 1, 4, 7 and 14 days, after force application, respectively. And Tissue slides of control and experimental groups were studied immunohistochemically and histologically. The results were as follows: 1. In 14days after force application, periodontal fibers were strectched on the tension side, and compressed in pressure side of all experimental groups, and the arrangement of periodontal fibers was not recovered yet. 2. The degree of EGF expression in control group was strongly positive in the oral epithelium, predentin, capillaries in pulp and periodontal spaces. But osteoblasts and osteoclasts were stained mildly positive. 3. EGF expression was mild and diffuse in 12 hours, 1, 4 and 7 days of experimental groups and was not significantly different between the tension and pressure sides. 4. The degree of EGF expression in the 14-day experimental group was higher than any other group. And the tension side showed a more positive EGF expression than the pressure side. The apical area revealed a more positive EGF expression than the cervical area.

BACKGROUND: Anomalous origin of a coronary artery is rare, but it can lead to angina pectoris, acute myocardial infarction, or even sudden death in the absence of atherosclerosis. Even when an anomalous vessel is identified angiographically, it may be difficult to delineate its true course on the basis of angiography alone. We attempted to determine whether transesophageal echocardiography (TEE) is of value in making the diagnosis and outlining the course of anomalous left circumflex (LCx) or right coronary arteries (RCA). METHOD: Eight adult patients with anomalous origin of LCx or RCA documented by selective coronary angiography were studied by transthoracic echocardiography (TTE) and multiplane TEE. RESULTS: Anomalous coronary ostia were visualized in all eight patients by TEE, but in only one with anomalous RCA out of eight patients by TTE. The proximal segments of anomalous coronary vessels were delineated in all eight patients by TEE and in only three with anomalous LCx out of eight patients by TTE. CONCLUSION: TEE is a valuable adjunctive diagnostic tool for the identification of anomalous coronary origin and course and is superior to TTE in adult patients.

Development of cataract is a well-documented ocular complication of systemic cortico steroid use in renal transplant patients. The purpose of this paper was to examine the result of cataracts in these patients and its correlation between development of cataract and steroid dose, rejection episodes, and human leukocyte antigen (HLA) type. Thirty patients (50 eyes) received cataract surgeries after renal transplantation. Thirty eight eyes (76%) were found to have posteiror subcapsular opacity. Forty seven eyes (96%) had a good postoperative visual acuity. Two eyes had a minimal macular edema, and other two eyes showed transient increase of intraocular pressure. The daily steroid dose of study group was significantly lower than that of control group. There was no significant correlation between cataract formation and rejection episode, cyclosporin dose and azathioprine use. HLA B13 was present in control group to a great extent (p<0.05). The surgical results of cataract in renal transplant patients were relatively good, and careful attention was needed when steroid dose was changed. We need further study about to prevent the formation of cataract.

Patients with central serous chorioretinopathy complain of decreased vision, micropsia, metamorphopsia, and central scotoma due to sensory retinal detachment. Morphologic characteristics of the sensory retinal detachment were described using Heidelberg retina tomograph. We inspected the changes in morphology according to certain time interval in 28 eyes and correlated them with the changes in visual acuity and symptoms. The mean width,length, height, area and volume of the detached sensory retina at initial examina- tion were 2.86 +/-1.08 mm, 2.60 +/-0.97mm, 0.30 +/-0.10mm, 6.82 +/-4.70mm2 and 0.77 +/-0.68mm3, respectively. Of the 7 eyes that had been followed, improvement of vision preceded improvement of other symptoms but, this was not statistically significant. The extent of sensory retinal detachment reduced with time and the maximal reduction occurred during the first month from the initial visit. The volume reduction (87.4%) was greater than the area reduction (52.3%) at the time of visual improvement

The Neurosensory retinal detachment contributes to the visual loss in the idiopathaic macular holes. Vitrectomy can be performed to reattach the retina by removing anterior-posterior and tangential traction between cortical vitreous and macular surface. Also bioadhesives, like autologous serum or platelets aggregates are used to flatten of surrounding rim detachment of macular holes. Among 22 eyes that underwent vitrectomy for the treatment of macular holes, anatomic success was achieved in 12 eyes (59.1%), and visual improvement in 10 eyes (45.5%). The time interval between diagnosis and operation was well-correlated to the functional success rate, while the type of surgical procedures was not. Postoperative complications included 2 cases of cataract, and 1 case of retinal detachment.
