Background and OBJECTIVE: There has been a few case reports of anaphylaxis due to honeybee in Korea. In order to observe the clinical feature of bee sting anaphylaxis. Moderials and methods: Six patients living in Kyunggi province area were referred under history of anaphylaxis after the bee sting. Atopy was defined by skin prick test result to common inhalant allergen. Serum specific IgE antibody to each bee antigen was detected by radioimmunoassay to identify the causative bee. RESULTS: All six cases were female. Three had atopy and four had combined allergic diseases such as allergic rhinitis, asthma, and urticaria. The etiologic bees consisted of yellow jacket (6 cases), paper wasp (4 cases), yellow hornet (3 cases), white faced hornet (1 case) and honey bee (1 case). Four cases had experienced anaphylaxis after ant bite and they showed positive result on specific IgE to imported fire ant. Specific immunotherapy against causative bee venom was begun using bee venom extracts from Bayer (USA) based upon results of specific IgE anti-body to bee venom. CONCLUSION: The yellow jacket is the most common cause of bee venom anaphylaxis in this area. Further studies will be needed to evaluate possible cross-reactivity between bee and ant venom.

Porokeratosis is a specific disorder of keratinization characterized histologically by the presence of a cornoid lamella. Clinically, the basic lesion is a sharply demarcated hyperkeratotic plaque which may be linear, punctated, or annular with central atrophy. The etiology of the various types of porokeratosis is unknown. However, heredity, UV radiation, immunosuppression, trauma, burns, and occult infection are known to be precipitating or exacerbating factors. A 32-year-old female was burnt on her right arm and chest at the age of 12. Several years later, brownish plaques developed in these burn areas. Seven years prior to visiting our clinic, nu- merous match-head sized, peripherally elevated macules developed on the forearms and have gradually spread to the other areas of her upper and lower extremities. The histological findings of two lesions from the burn areas showed the same features including cornoid lamellae in the epidermis and fibrosis in the dermis. Howerer, the histological finding of a lesion from a non-burn area showed cornoid lamellae in the epidermis without evidence of dermal fibrosis. We believe our case is the first to be reported in Korea in which porokeratosis arose in previous burn areas.

BACKGROUND: Herpes zoster(HZ), caused by reactivation of latent varicella-zoster virus, is manifested by dermatomal distribution of skin rashes, acute pain and post-herpetic neuralgia by pathologic involvement of the sensory ganglia. Low-energy laser(LEL) deliver a small amount of energy without elevation of the tissue temperature. LEL is reported to have various biologic effects such as anti-inflammatory, analgesic, regenerative, antiallergic, immunocorrective, and antibacterial effects. OBJECTIVE: We attempted to evaluate the therapeutic effect of LEL on an acute phase of HZ. METHODS: A total of 60 patients with acute HZ were enrolled in the study. The control group(30 patients) received medications including analgesics, antihistamine, and topical care without LEL irradiation. The experimental group(30 patients) were irradiated with LEL daily for 7 days in addition to the same kinds of medications for the control group. The efficacy of LEL irradiation for HZ was assessed by analyzing changes in skin rashes, pain scores, and postherpetic neuralgia.

Lupus erythematosus panniculitis is a rare variant of lupus erythematosus primarily involving a panniculus with or without discoid lupus erythematosus in the overlying skin. A 34-year-old woman showed multiple, variable-sized, indurated subcutaneous nodules on both her upper arms and axillae. A Histopathological examination revealed lobular panniculitis with infiltration of several hyperchromatic atypical large lymphocytes. The infiltrated cells were positively stained with LCA, UCHL-1, CD4, CD8, but not with CD20 and CD68. A T cell receptor -chain gene and immunoglobulin heavy chain gene rearrangement study showed no monoclonality. The result of an ANA test was positive at 1: 40 in a homogeneous pattern. Skin lesions were improved by combined therapy with daily hydroxychloroquine 400mg and prednisolone 10mg in a week and after 6weeks, resolved with atrophic depressed scars. After 4 months, she complained of symptoms of the Raynaud phenomenon and was managed by nifedipine. There has been no recurrence during follow-up for 7 months.

Background: A bloodstream infection is a life-threatening medical emergency, with a mortality rate of up to 30%. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) can be used to identify pathogens directly from positive blood cultures. Two commercial preparation kits, SepsiTyper (Bruker Daltonics, Germany) and SepsiPrep (ASTA Corp., Korea), and two MALDI-TOF MS systems, MALDI Biotyper Sirius (Bruker Daltonics, Germany) and VITEK MS PRIME (bioMérieux, France), are available in Korea. We examined these kits and MALDI-TOF MS systems to analyze their performance. Methods: We assessed the effectiveness of direct identification using 47 blood cultures and 3 bile cultures positive for microbial growth. The VIRTUO system (bioMérieux, France) was used to incubate the samples after they were collected in Bact/ALERT aerobic and anaerobic bottles. The manufacturers’ protocols were followed for both the SepsiTyper and SepsiPrep kits. Results: The SepsiTyper yielded considerably more accurate identifications than did the SepsiPrep, when utilized in MALDI-TOF MS systems (P = 0.0044). However, the SepsiPrep was easier to use and the results more quickly obtained than with the SepsiTyper. The MALDI Biotyper Sirius produced more accurate identifications with the SepsiTyper than did the VITEK MS PRIME (P = 0.0736). The SepsiTyper enabled the accurate identification of five of six polymicrobial cases, utilizing either the MALDI-TOF MS systems. Conclusions Among the pathogen ID kits tested in this study, the SepsiTyper with MALDI Biotyper Sirius performed the best. In clinical laboratories utilizing VITEK MS PRIME, it is recommended that the either the SepsiTyper or SepsiPrep kit be used for direct identification, while considering certain limitations in terms of performance.

Purpose: The diagnostic usefulness of fetal echocardiography in congenital heart disease is well known. One of the indications for fetal echocardiography is presence of extracardiac anomalies and such coexistent congenital heart disease may have important implications for obstetric and neonatal management. MATERIALS AND METHODS: 496 women with singleton pegnancies with amgenital anomalies that underwent penatal care and follow-up in Severance Hospital for 5 years from 1991 to 1995 were evaluated for the incidence of congenital heart disease. RESULTS: The incidence of congenital heart disease in fetuses with the associated extracardiac anomalies were as follows; central nervous system 6.9%(11/160), gastro-intestinal system 10.7%(8/75), genito-urinary sysem 4.7%(4/85), others 5.6%(4/72). Thirty-one of eighty-ane fetuses with congenital heart disease were found to have the associated extracardidac anomalies and ten of them chenoscenal abnormalities. CONCLUSION: We recommend that fetuses with congenital extracardiac anomalies sbould be checked for the presence of congenital heart disease and chmmosomal abnormalities, if needed.
