Chloramphenicol ophthalmic solut,ion is a commonly used eye drui in the treatment of superficial eye infection because of its wide antibacterial spectrum and easy peitation in the ocular tissue and aqueous humor. The true contact dermat it is to chloramphenicol is rarely reported. A case of contact. dermatii,is due to chloramphenicol in a 6-year-old girl was confirmed by the patch test. Marked improvement of the skin lesion and symptoms were rated after the withdrawal of topieal application of the chloramphericol ophthalmic solution.

BACKGROUND: It has been known that blood group antibodies are not produced in the neonatal period and that if the antibodies exist, they are probably maternal in origin which had crossed the placenta. There have been several studies conducted abroad on when these antibodies are formed but none has been done in Korea. This study was carried out to determine the ABO blood type and blood group antibodies in children from neonates up to 5 year old. We hoped to determine when and in what pattern blood group antibodies were produced. METHODS: We selected 337 children from neonates up to 5 year old who were admitted to Hanyang university Hospital in Seoul or Kuri from 1994 to 1996. Cell typing was done immediately by the slide method. The anti-A and anti-B used for cell typing were supplied by Immucor (Norcrosis, Ga) . Sera were stored at -70 degrees C until they were tested for ABO blood group antibodies by the standard saline test tube method. When uncertain results were obtained, a drop of the mixture was placed on a slide and observed under a microscope. RESULTS: ABO blood group antibodies were detected in 9 of 50 (18%) infants less than 1 week old and in 10 of 51 (20%) infants between 1 week and 3 months of age. The pattern of ABO blood group antibody production was similar to that of the fetal period up to 3 months after birth, after which antibody production increased rapidly to reach approximately 80% at 6 months of age, There was no difference in ABO antibody production between boys and girls. The antibody formation pattern of group A and group B infants less than 6 months of age showed anti-A to be 35% and anti-B to be 20%. In group O infants of the same age, anti-A was positive In 42% and antral-B In 33%. However, after 6 months of age, there was no difference in antibody production among groups A, B, or O. CONCLUSIONS: Antibodies directed toward ABO antigens were detected in 19 out of 101 (19%) infants less than 3 months old. We therefore believe it is necessary to Perform serologic typing as well as cell typing in these Infants. Furthermore, the emergency transfusion of type A or B blood to a type O infant under the impression that anti-A and anti-B do not exist should be forbidden.

Trichoblastic fibroma is a rare benign tumor of hair germ with mixed epithelial-mesenchymal components. A 64-year-old female presented with an asymptomatic, skin-colored, firm nodule on the left knee joint. Histopathologic examination showed multiple tumor islands and strands eomposed of basaloids cells embedded in a moderately cellular fibroblastic stroma and the for vation of bud-like extension of tumor cell nest. The peripherel basaloid cells shovred a palisading arrangement and small keratinous cysts were formed in tumor islands.

BACKGROUND AND OBJECTIVES: The identification of a specific etiology of effusive pericardial disease is difficult because of the limited yield of cytologic and microbiologic pericardial fluid analysis. We performed retrospective study to find out whether pericardial biopsy was superior to pericardial fluid analysis in search of the etiology of pericardial effusion. MATERIALS AND METHOD: We reviewed 76 cases of moderate to severe pericardial effusion on which we performed surgical pericardial biopsy from Sep. 1986 to Sep. 1996. The results of pericardial fluid analysis, clinical manifestation, pericardial biopsy were compared retrospectively. RESULTS: 1)Clinical diagnosis of pericardial effusion were as follow:neoplastic disease (7.9%), tuberculosis (72.4%), constrictive pericarditis (17.1%), and others (2.6%). 2)By the percutaneous pericardial biopsy, we confirmed 19 cases (25%). Etiology of 4 cases (5.3%) were malignancy and 15 cases (19.7%) tuberculosis. Fifteen out of 76 patients who were diagnosed by biopsy as tuberculous pericarditis and 28 patients who were suspected as tuberculous pericarditis clinically were treated with antituberculous medications. Ten patients (66.7%) of pathologically diagnosed patients and 18 patients (69.2%) of clinically diagnosed patients showed complete resolution of pericarditis. CONCLUSION: By pericardial biopsy, we only confirmed 19 cases (25.0%). It means that pericardial biopsy is not superior to pericardial fluid analysis in searching of etiology of pericardial effusion. Moreover, it is not sufficient for final diagnosis of pericardial effusion.

BACKGROUND: Calcipotrol, topical vitamin D analogue, has been demonstrated to have an effect for the treatment of psoriasis with good tolerability. It is required to have comparative studies with the other topical agents which are widely used for the treatment of psoriasis. OBJECTIVE: Our purpose is to compare calcipotriol with desoxymethasone ointemtn in their therapeutic efficacy and ability to affect dermal inflammatory cellular events. METHODS: This study was a randomized, double blind, right/left comparison over 8weeks in 10 patients. The ointments were applied twice daily to the lesions of psoriasis. Clinical efficacy, as measured by the Psoriasis Area and Severity Index(PASI) was assessed at 2, 4, 6 and 8weeks after starting treatments. The changes in the numbers of dermal immunocytes were assessed on frozen and paraffin-embedded sections by using immunohistochemical stain methods before and after the treatemtns. RESULTS: Reduction of PASI was statistically significant at all time points for both of the treatments (P<0.01) but there was no significant defference between the two treatment modalities. At the completion of 8 weeks of treatments, the mean PASI reduction was 65 percents and 67 percents for calcipotriol and desoxymethasone ointments, respectively. On immunohistochemical staining, the numbers of LCA and HLA-DR positive cells were decreased significantly(P<0.05), and IL-2R and CD4 positive cells were not significaltly reduced in each group after the treatment. CONCLUSION: Calcipotriol ointment was as effective as desoxymethasone ointment, judged by the PASI and the dermal inflammatory cellular events on immunohistochemical staining.

Korean Journal of Dermatology 1994;32(5):802-808
BACKGROUND: It is well-known that the giant congenital nevi prcgress to malignant, melanama more frequently than other benign melanocytic nevi but to date the laor tory methods for early detection of such progression were not avsilable. The proliferating cell uncleai antigen(PCNA) staining has been regsrded as an useful marker in determining prognosis of some maignant diseases. OBJECTIVE: The PCNA taining was performed as a predictive value of malignant transformation from benign meanocytic skin lesions. We investigated the differcnces between malignant melanoma and the benign lesions. MATERIAL AND METHODS: Immunohistochemical study was employee using anti-PCNA, anti-S-100, and anti-CD45RO antibody in 6 giant congenital nevi, 8 small and medium sized congenital nevi, 10 acquired nevi, and 10 malignant meanomas. Only cells positive for both PCNA and S-100, and negative for CD45RO on the serial sections were identified as melanocyts. RESULTS: The number of PCNA-posit,ive cells per 1000 melanocy,es averaged 6.0+7.5 in giant, congenital nevi, 2.9+1,9 in small and medium sized congenital novi, 3.1+2.7 in acquired nevi, and 61.5+ 39.4 in malignant, melanomas. Malignant melanomas showed onger intensity of PCNA staining than the other melanocytir nevi. CONCLUSION: There was not significant difference of the numter of PCNA-positive cells among the groups of congenital neviind PCNA staining can't be used in prditive measure of malignant. progression and studying mechansm of malignancy in giant congenital nevi. But, PCNA staining is considered as an useful method in differentiat,ing malignant melanoma from mllanocytic nevi.

Higt energy electron beam therapy is a method which is used for the treatment of superficial tumors (less than 5 cm deep) with a characteristically sharp drop-off in dose beyond the tumor. This method offers distinct advantages in dose uniformity and in minimizing the dose to deeper tissues. We report herein three cases of epithelial skin cancer treated with high energy electron beam. The first patient was a 79-year-old male who had primary basal cell carcinoma(BCC) on the right lateral canthus. The second patient was a 67-year-old male who had recurreiit BCC on the right cheek. Both of them received electron beam therapy on the lesion and there were no clinical relapse signs over 1 year. The third patient was a 46-year-old male who had squamous cells, carcinoma on the lower lip. He also received electron beam therapy on the lesion, but it recurred.

Human seminal plasrna (HSP) is mixture of secretion derived from various glands associated with male reproductive tract which comprises approximately 80-90% of the volume of normal ejaculate. The present study was undertaken in an effort to explore the effect of HSP pretreatment on the production of IL-1B, TNF-a and IL-12, in mice, and to investigate if HSP may cause to induce active systemic anaphylaxis (ASA) in mice. In addition, effects of HSP pretreatment on contact hypersensitivity to trinitrochlorobenzene (TNCB), antibody response to polyvinylpyrroridone (PVP), a thymus-independent antigen and on ASA induced by egg albumin (OVA) were also studied in this study. For the experiments of contact hypersensitivity, antibody response and cytokine production, mice were pretreated i.p. daily with 0.3ml of HSP or sterile saline alone (control) for 3 consecutive days before antigen sensitization or lipopolysaccharide injection for the cytokine induction. For the experiments of OVA- induced anaphylaxis, mice were pretreated by a single s.c. injection of HSP 0.3ml per mouse before sensitization. For induction of ASA in mice by HSP, a group of mice were sensitized i.p. 2 consecutive days with 0.3ml of HSP and one day with 0.3 ml of HSP plus 2x10(9) B. pertussis and 1.0 mg of alum (schedule A) or another group of mice were sensitized i.p. with a single i.p. injection of 0.3 ml of HSP with 2x10' B. pertussis and 1.0 mg of alum (schedule B). All sensitized and unsensitized control mice were challenged i.v. with 0.2ml of HSP 14 days after HSP sensitization, and mortality were observed. It was found that HSP pretreatment inhibited the production of IL-lB, TNF-a and IL-12, and also inhibited OVA-induced ASA, contact hypersensitivity to TNCB and anti-PVP antibody production. Interestingly, ASA was induced by HSP irrespective of the applied sensitization schedule. Taken together, this study may provide the direct evidences that HSP may inhibit the production of IL-1B, TNF-a and IL-12 and this may be the first to show the induction of ASA by HSP in mice.
