Chronic actinic dermatitis was recently proposed to be a syndrome of chronic photosen-sitivity that incudes photosensitive eczema, persitent light reection, photosensitivity dermatitis and actinic reticuloid. We report herein a case of chronic actinic dermatitis which occured in a 60-year-old man. He suffered from a chronic eczematous dermatitis affecting e posed skin and some covered area with a feature of erythroderma. Phototesting showed abnormal photosensitivity to both UVB and UVA as will as to visible light. Skin biopsy specimes revealed histologic findings of spongiotic dermatitis in which dermal infiltrates were mainy consisted of T lymphocytes with suppressor T cells dominance on immunohistochemistry.

Human lymphoblastoid B-cell lines immortalized by Epstein-Barr virus (EBV) were established from peripheral blood of patients with acute myeloblastic and chronic lymphocytic leukemia and chronic fatigue syndrome. The sera of patients with acute myeloblastic and chronic lymphocytic leukemia did not show antibodies to Epstein-Barr viral capsid antigen (VCA), but serum of a patient with chronic fatigue syndrome disclosed antibodies to VCA (IgG, IgM), and EBNA was demonstrated in peripheral blood mononuclear cells by polymerase chain reaction. The established cell lines were mature B-cell phenotypes with polyclonal proliferation in early passage and no evidence for commitment to other lineages. The immortalized cells by EBV were designated as CSUP-1 and CSUP-2 (from acute myeloblastic leukemia, FAB classification M2 and M1), CSUP-3 (from chronic lymphocytic leukemia) and CSUP-4 (from a patient with chronic fatigue syndrome). The CSUP-1, 2, 3, and 4 grew in suspension forming clumps with a doubling time of 38 to 49 hours. Colony formation was not recognized in plate. By light and electron microscopic examination, the immortalized cells showed features of lymphoblastoid to plasmacytoid lymphocytes, and multinucleated giant cells. The lymphoblastoid cells showed scanty cytoplasm with poorly developed organelles. Immunophenotypic analyses of CUSP-1, 2, 3, and 4 with monoclonal antibodies by flow cytometry showed B-cell phenotype with polyclonal proliferation in early passage. Epstein-Barr virus nuclear antigen was confirmed in the extracted DNAs from immortalized cells by polymerase chain reaction. DNA analysis showed a normodiploid stemline with a DNA index of 1.12. The established cells were strongly reactive for CD10, CD30 (Ki-1) in early passage, and bcl-2 and c-myc onco-protein in early and late passage. Karyotypic analysis of CSUP-1, 2, 3 and 4 showed 46, XY or 46, XX. No tumorigenesis in heterotransplanted SCID mouse was recognized. This immortalized cells by EBV should be a valuable cell lines to study the pathogenesis of EBV-related malignant lymphoma.

Befunolol hydrochloride is a B-adrenergic receptor antagonist cornnory used topically in treatment of glaucoma because of a satisfactory intraocular pressure lowering apcity without relevant topical or systemic side effects. We repart herein a case of allergic contact dermatit.is due to befunc ol nydrochloride in 0.5% Bentos eyedrops, A 52-year-old Korean woman had suffered from erythemanedema with itching sensation on her left eye since Novembeir 18, 1992. She had used various ophtalrnic preparations including Bentos eyedrops containing befinolol hydrochloride 0,5% as its activ cinstituent since October, 1992 for treatment of glaucoma of her left eye. Patch test with the European standard series, rubber series, the patiants eyedrops and their individual constituents showed positive. reactions only to 0.5% Bentos eyedrops(as is) and to befunolol hydrochloride. We noted rapid improvement of skin lesions and syipsms after the withdrawal of Bentos eyedrops and applicatior of another B-blocker(carteolol hydrocilcide).

BACKGROUND: Persistent facial elangiectssia, erythema, and flushing are the major cosmetic problems in patients with rosacea, However various therapeutic modalities for roacea papules and pustules, including topical antibiotics, systemic antibiotics, isotretinoin, and systernic and topical metronidazole, are not effective in reducing telangiectasia and flushing reactions present inrosacea patients. The flashlamp-pumped pulsed dye laser has been deacribed as a succqssful treatment for port wine stains with telangiectasia as part of their abnomalities. A clinical study was therefore undertaken in a group of rosacea patients, who recieves this laser to areas of facial taieous lesions. OBJECTIVE: The purpose of the study was to evaluate the therapeutic effect of the flashlamp-pumped pulsed dye laser(SPTL-1) for osacea, especially telangiectasia and flusing reactions. METHODS: Forty-eight. patient with rosacea were studied to evaluatic the therapeutic effects of the SPTL-1 flashlamp-pumped pulsed dye laser (Candela corp.Wayland Mass.) at the Department of Dermatology in Dong-A University Hospital for 20 months from Januarg 1991 to August 1992. RESULTS: 1. Total therapeutic effects of this SPTL-1 laser showed excellent re:ults in 22.9%, good in 62.5%, fair in 8.3%, and poor in 6.3%. 2. Therapeutic effects of rosacea-associated lesions showed exeellerit or good results in 85.4% of patient,s with erythema and telangiectasia, 84% patients with papules, 100% patients with pustules, and 93.7% of patients with facial flushing. 3. Complications included trarsient hyperpigmentation (14.6%), section lary bacterial infection(6.3%), hypopigmentation(2.1%), and atropic scar(2.1%). 4. The recurrence rat.e was 2,9,%. CONCLUSION: The flashlamp-pumped pulsed dye laser (SPTL-1) is a dry effective mode of treatment for rosacea, including persistent telangiectasia and facial flushing ri.actions which were intractable to previous other therapeutic modalities.
