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.

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).

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.

This study was carried out to obtain the basic data for artificial culture of veiled lady mushroom (Dictyophora spp). The optimal conditions for the mycelial growth were 25degrees C and pH 5.0 for all isolates except the optimal temperature of 30degrees C for D. echinovolvata ASI 32002 and Phallus rugulosus . The optimal medium for Dictyophora spp. was PBA (potato bamboo sawdust extract agar) medium. The strain ASI 32002, D. echinovolvata , grew faster than. D. indusiata ASI 32003 and Phallus rugulosus ASI 25007 on the medium. Carbon sources such as glucose, maltose and inuline were favorable for stimulating a mycelial growth of the two strains of ASI 32002 and ASI 32003. Asparagine and glutamine appeared to be favorable to the strain ASI 32002 and ASI 32003, where as alanine, one of nitrogen source also favorable to the strain ASI 32002. The optimum C/N ratio of the two isolates of ASI 32002 and ASI 32003 was about 25 : 1 when 2% glucose as carbon source was mixed with the basal medium. While, in the case of 4% as carbon source, the optimum C/N ratio was about 30 : 1.

Few studies have assessed the neural mechanisms of the effects of emotion on cognition in generalized anxiety disorder (GAD) patients. In this functional MRI (fMRI), we investigated the effects of emotional interference on working memory (WM) maintenance in GAD patients. Fifteen patients with GAD participated in this study. Event-related fMRI data were obtained while the participants performed a WM task (face recognition) with neutral and anxiety-provoking distracters. The GAD patients showed impaired performance in WM task during emotional distracters and showed greater activation on brain regions such as DLPFC, VLPFC, amygdala, hippocampus which are responsible for the active maintenance of goal relevant information in WM and emotional processing. Although our results are not conclusive, our finding cautiously suggests the cognitive-affective interaction in GAD patients which shown interfering effect of emotional distracters on WM maintenance.

Generalized sterile pustular eruptions occur in various dermatoses including pustular psoriasis, erythema multiforme, Sneddon-Wilkinsan disease and others. Recentlr, acute eruptions of disseminated sterile pustules have been reported. The etiology is not related to a gepetic predisposition to psoriasis but to drug ingestion or viral infections, thus termed toxic pustuloderm; (T. P.). In this report, we present a typical case of T. P. observed iu our department. Our patient, an 18-year-old male, with no personal or family history of psoriasis, was given drug medication including amoxicillin for fever and chilling sensation. Pustilar eruptions first, appeared on his face about two days aft.er the medication and gradually spread to the trunk and limbs. The skin examination revealed numerous small pustules on an erythematous base. Laboratory examination revealed neutrophilic leukocytosis and an elevated sedimentation rate skin biopsy showed subeorneal and spongiform neutrophilic pustules Upon interruption of the amoxicillin, the pustules cleared rapidly in 3 days and there has been ri.o recui rence of any rash over a 7-month follow-up period.

9.Molecular targeted therapy for advanced gastric cancer.
The Korean Journal of Internal Medicine 2013;28(2):149-155
Although medical treatment has been shown to improve quality of life and prolong survival, no significant progress has been made in the treatment of advanced gastric cancer (AGC) within the last two decades. Thus, the optimum standard first-line chemotherapy regimen for AGC remains debatable, and most responses to chemotherapy are partial and of short duration; the median survival is approximately 7 to 11 months, and survival at 2 years is exceptionally > 10%. Recently, remarkable progress in tumor biology has led to the development of new agents that target critical aspects of oncogenic pathways. For AGC, many molecular targeting agents have been evaluated in international randomized studies, and trastuzumab, an anti-HER-2 monoclonal antibody, has shown antitumor activity against HER-2-positive AGC. However, this benefit is limited to only ~20% of patients with AGC (patients with HER-2-positive AGC). Therefore, there remains a critical need for both the development of more effective agents and the identification of molecular predictive and prognostic markers to select those patients who will benefit most from specific chemotherapeutic regimens and targeted therapies.

Targetoid hemosiderotic hemangioma is a benign vascular tumor with a peculiar clinical presentation and histologic features sometimes difficult to differentiate from the patch stage of Kaposi's sarcoma, progressive lymphangioma, eosinophilic hemangioma, retiform hemangioendothelioma. We report a case of targetoid hemosiderotic hemangioma on upper back and right upper arm of a 28-year-old male. He has a 5mm × 5mm sized slightly raised violaceous papule surrounded by an ecchymotic halo on upper back and right upper arm. We took a biopsy of the lesion and identified it as targetoid hemosiderotic hemangioma. This is a case of targetoid hemosiderotic hemangioma with typical clinical and histopathological findings.
