The nipple involvement in atopic dermatitis is not mentioned in currently available major textbooks of dermatology. Recently, Hanifin and Rajka indicated that the nipple involvement is a specific indicator of atopic dermatitis though it is quite rare. The authors described 3 cases of atopic dermatitis with nipple involvement among 224 cases of atopic dermatitis seen over 2 year period at the Special Clinic for Atoipc Dermatitis. The nipple lesions responded to topical steroid quite satisfactorily.

BACKGROUND: Ischemic preconditioning reduces the infarct size and the severity of arrhythmia in a post-ischemic reperfused heart although the detailed mechanism is unknown. In the ischemic heart, a large amount of catecholamine is released from the adrenergic nerve terminal and this aggravates cell destruction and arrhythmia. In this study, the possibility for ischemic preconditioning to inhibit the release of endogenous catecholamine from the ischemic heart was tested to investigate the probable cardioprotective mechanism of ischemic preconditioning. METHODS: In the isolated, Langendorff perfused rat hearts, we observed the protective effect of ischemic preconditioning against post-ischemic reperfusion injury, and measured the amount of catecholamine released into coronary effuent. In addition, we observed the effect of catecholamine depletion on reperfusion injury in non-preconditioned and preconditioned hearts. RESULTS: During the reperfusion(20min) after ischemia(30min), the cardiac function was markedly depressed with the development of severe contracture. In the heart preconditioned by three sequential episodes of 5min ischemia and 5min reperfusion, the reperfusion contracture decreased significantly and the cardiac function was almost recovered to normal after 20min reperfusion. The release of lactate dehydrogenase was also decreased in the preconditioned heart. The release of endogenous catecholamine was abruptly increased immediately after the reperfusion and the release was exponentially decreased throughout the reperfusion period. THe pattern of catecholamine release was much different from that of lactate dehydrogenase release. In the preconditioned heart, the release was significantly decreased to about half of that in non-preconditioned t\heart. Endogenous catecholamine depletion by reserpine treatment did not affect the post-ischemic functional recovery in both non-preconditioned and preconditioned hearts. CONCLUSION: It is suggested from these results that ischemic preconditioning inhibis the release of endogenous catecholamine during ischemic period, which may be partly related to cardioporotective effect of preconditioning in ischemic and reperfused heart.

Senile sebaceous hyperplasia refers to a benign enlargement of a normal sebaceous unit which is not uncommon in the old age group, and is characterized clinically by single or multiple small cream to yellowish round papules developed on the face, chiefly on the forehead and cheeks. A case of florid senile sebaceous hyperplasia developed in a 81-year-old man was presented. Because this disorder is one of the geriatric dermatoses and the average life span of our people is remarkably lengthened in recent years, we believe dermatologists should pay more attention to this kind of dermatosis.

Two cases of epidertnoid cyst of the ovary are added to the ten reported in the literature. This rare lesion is usually an incidental finding. Its main interest is in its histogenesis, which includes metaplasia of the coelomic surface epithelium, monophyletic development of teratoma, and metaplasia of the rete ovarii. We investigated two cases of epidertnoid cyst. Histologic examination of the cysts showed a thin lining of mature keratinizing squamous epithelium rectum: unaccompanied by skin appendages or other teratomatous elements.

The close similarity of acrokeratosis verruciformis(AKV) to the acral lesions of Dariers disease is well known. However, the exact relationship between the two disorders has not been satisfactorily resolved. A case of Dariers disease associated with guttate leukoderma and AKV is presented. The patient was a 17-year-old male who had dark cursted papules on the neck and lower abdomen, flat-topped keratotic papules on the dorsal surface of hoth hands, and white macules disseminated on the trunk and lower extremities of 7 years duration. The histopathologic examination of the lesion on the lower abdomen revealed parakeratotic plugs, corps ronds, and suprabasal clefts. The lesion on the dorsum of the hand showed compact hyperkeratosis, acanthosis, and papillomatosis with the pattern of church spires. The leukodermic lesion revealed decreased melanin content in the epidermal cells.

The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n=16, 100%), hyperattenuation of MCA (n=3), obscuration of lentiform nucleus (n=6), loss of insular ribbon (n=6) and subtle low density in hemisphere (n=5). The most frequent findings was effacement of cortical sulci in our study, and it was though to be the most important sign of early acute cerebral infarction.

The formation of spontaneous rosettes between human lymphocytes and sheep erythro ytes under suitable conditions is a constant feature of T-lymphocytes. Recently. It has been demonstrated in the mouse, rat, guinea pig and in man that a certain proportion of peripheral blood lymphocytes has the property to bind autolognus erythrocytes in vitro. These lymphocytes are called auiologous rosette forming cells(ARFC). Although there are several reports on human ARFC. the results are not in accordance. The present study was undertaken to demonstrate the autologous rosette forming property of human peripheral blood lymphocytes, and to enumerate the percentage of ARFC in different sex and age guoups. Fifty healthy persons entered this study between Martch and September. 1980. at the Department of Dermatolgy, Seoul National Universty Hospital. The method of quantitation of AREC was s sight modification of that of Lambermont et al(1977). The results were as follows.

PURPOSE: Choroid Plexus papilloma is a rare intracranial neoplasm that is most commonly found in the trigone of the lateral ventricle in children or in the fourth ventricle in adult. Extraventricular extension of choroid plexus papilloma has been rarely reported within the cerebellopontine angle (CPA) cistern. Authors report two cases of choroid plexus papilloma in the posterior fossa seen on magnetic resonance imaging (MRI). MATERIALS AND METHODS: MRI findings of two cases of choroid plexus papilloma in posterior fossa were retrospectively reviewed. RESULTS: In the first case, the tumor was in the fourth ventricle and extended to the left CPA cistern via the foramen of Luschka. In the second case, the tumor presented as an expansile mass of the of fourth ventricle and right lateral recess. Multiple signal voids of low intensity due to prominent feeding vessels and calcifications within the tumors were noted. CONCLUSION: This report demonstrates MR findings of choroid plexus papilloma in the posterior fossa with the brief review of the literatures.
