Respiratory syncytial virus (RSV) and Influenza virus are the most common pathogen for causing severe upper respiratory infection in all age groups. A multiplex reverse transcription polymerase chain reaction (RT-PCR) has been developed to detect and subtype influenza A (H3N2 and H1N1), B virus and RSV simultaneously in one tube reaction. Amplification with primers derived from conserved sequences within the nucleocapsid for RSV and hemagglutinin subunit for Influenza A (H3N2 and H1N1) and B viruses yielded a 384 bp, a 300 bp, a 236 bp and a 151 bp, respectively. Assay specificity was confirmed by pulse field gel electrophoresis and autosequencing method. Assay sensitivity was 3 PFU/ml of RSV, 22 PFU/ml, 45 PFU/ml of Influenza type A (H3N2 and H1N1) and 6.6 PFU/ml of Influenza B virus by plaque assay. A rapid and sensitive detection method of a one-tube with multiplex RT-PCR capable of identifying more than one viral template as well as synchronizing reverse transcription and PCR had the potential to produce considerable savings of time and cost effectiveness in the diagnostic laboratory.

PURPOSE: The globe luxation is a rare phenomenon in which there is a forward displacement of the eye ball so that the eye lids spasmodically close behind it. In Korea, no case has been reported. The authors experienced a case of globe luxation by laceration of the conjunctiva with trauma. METHODS: The authors experienced a case of globe luxation in 64-year-old male who had crushed with infantile marry-go-round handle and complained proptosis and ocular pain. Ocular examination revealed best corrected visual acuity of right eye 0.1, IOP 44mmHg, conjunctival hyperemia and laceration, extraocular muscle limitation in all direction. Exophthalmometer shows right eye 23mm, left eye 19mm. Orbital CT yielded proptosis and globe luxation without avulsion of internal and external rectus muscle and optic nerve. RESULTS: After the lateral canthotomy, we successfully treated with the corticosteroid therapy without visual impairment or eyeball movement disorder. we report a case of globe luxation with the review of literature.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

PURPOSE: To analyse the macular thickness in normal and diabetic patient using OCT mapping protocol. METHODS: OCT using macular thickness map protocol was performed in 46 eyes of 25 healthy volunteers and 121 eyes of 85 diabetic patients with clinical diagnosis of no diabetic retinopathy (25 eyes), nonproliferative diabetic retinopathy (NPDR) without clinically significant macular edema (CSME; 35 eyes), proliferative diabetic retinopathy (PDR) without CSME (27 eyes), and diabetic retinopathy with CSME (34 eyes). RESULTS: The mean +/- standard deviation foveal thickness was 146 +/- 21 micrometer in normal eyes, 147 +/- 20 micrometer in diabetic eyes without retinopathy, 173 +/- 24 micrometer in NPDR without CSME, 174 +/- 27 micrometer in PDR without CSME, and 322 +/- 146 micrometer in diabetic retinopathy with CSME. There was significant difference in foveal and outer temporal retinal thickness between the normal eyes and the diabetic retinopathy without CSME group (p<0.01). Diabetic eyes with CSME had a statistically significant greater thickness in each of the areas compared with the other group and showed perifoveal focal macular edema in 5 eyes. CONCLUSIONS: OCT mapping protocol provide intuitive and objective information on focal diabetic macular edema.

A case of chronic granulomatous infection of Fsarium solani had decreased response to recalled antigens and lacked of dinitrochlorobenzene(DNCB) sensitization in vivo. He has had frequent attacks of common cold-like symptoms and same attacks were very suggestive of pneumonia but he relatively healthy until he developed cutaneous Fusarium infection. Recently he also developed herpes zoster.

Adherence of Candida albicans(C. albicans) to the surface of a denture is believed to be an initial and essential step in the formation of denture-induced stomatitis. Previous studies have provided enormous infomation on the relationship between composition of palatine gland/parotid saliva and upper denture stomatitis. Relatively little information is available on the correlation between lower denture stomatitis and sublingual-submandibular(SLSM) saliva. The plaque samples were collected from the two sites(100mm2) on the inner surface of lower partial denture corresponding to the stomatitis and healthy region of the lower partial dentures of 12 denture stomatitis patients and 6 normal persons who wore lower partial dentures. The samples were plated to isolate C. albicans on a selective Saboraud's dextrose agar plate and the isolates were identified by germ tube test and gram staining. The subjects were divided into group I (stomatitis with C. albican), group II (lesion without C. albicans), group III (no lesion but C. albicans), and group IV (normal and healthy denture wearer). Individual SLSM saliva (20microgram of protein) was analyzed by SDS-PAGE(SDS-poly-acrylamide gel electrophoresis) with Coomassie brilliant blue and PAS(Periodic Acid Schiff) staining. The salivary proteins separated in the polyacryamide gels were subjected to immunoblot analysis using anti-lactoferrin, anti-sIgA, and anti-secretory component of sIgA. In this study using custom made acrylic denture resin beads(5mm in diameter) coated with stimulated individual SLSM saliva, the binding ability of individual C. albicans strains to the beads was observed. Levels of C. albicans adhered to the acrylic resin beads were determined by measuring the optical density of the bound C. albicans to the beads at 580nm. The results showed that a higher number of C. albicans was observed in the lesion site than health site. The saliva of group I contained more high molecular weight glycoprotein(mucin, MG1) as compared to group II, III, and IV. And lactoferrin and sIgA affected to the binding ability of C. albicans to acylic resin beads. Binding ability of individual C. albicans to the acrylic resin coated with respective individual saliva was found to be greater in group I than the other 3 groups. And when bound cells of C. albicans isolated from individual subject #2 to the saliva coated beads were used, binding ability of subject #2 saliva coated beads was founed to be greater than the other subjects. These results suggested that denture induced stomatitis is related to individual patient's salivary protein composition, especially MG-1. Future studies will be directed toward saliva examination of patients who have general disease and analysis of pellicles formed on prosthesis with respect to oral disease.

Neonatal diabetes mellitus (NDM) is defined as hyperglycemia that presents clinical symptoms within the first month of life and requires insulin therapy to maintain euglycemia. The diabetic condition may be transient, permanent, or transient with recurrence later in life. NDM is a rare clinical disorder. Three cases of NDM have been reported in Korea so far. We experienced two cases of NDM in twin brothers who were born with small for gestational ages. Their HLA typings were DR9 and DR14, and insulin autoantibody, islet cell antibody, GAD-reactive autoantibody, and insulin receptor antibody were not found. The genetic analysis with polymorphic DNA markers for chromosome 6 indicated paternal uniparental isodisomy.

Perfluorodecalin, which is one of the perfluorocarbon liquids, is not established safety in use of long-acting intraocular tamponade. Therefore, to determine its safety we injected it alone and combined with silicone oil into the vitreous of vitrectomized eyes. We evaluated the changes of the fundus, electroretinogram, histopathology as light and electron microgragh after lensectomy and vitrectomy in pigmented rabbits periodically. In rabbits replaced with perfluorodecalin alone, fundus showed mild proliferative vitreoretinopathy and micrographs showed the destruction of the inner and outer segments of the photoreceptors. In rabbits replaced with perfluorodecalin and silicone oil, fundus showed more severe proliferative vitreoretinopathy than perfluorodecalin alone and micrographs showed the destruction of the entire retina. In electroretinogram, the amplitude was decreased markedly. So, it is considered that perfluorodecalin was not tolerant in case of longacting intraocular tamponade and also perfluorodecalin combined with silicone oil developed severe proliferative vitreoretinopathy.
