Sarah Bartram, B.Sc. Flow Cytometry ipl.qxd 11/12/06 11:14 Page 2 Preface How can I explain what flow cytometry is to someone that knows nothing about it? Well, imagine it to be a lot like visiting a supermarket. You choose the goods you want and take them to the cashier. Usually you have to pile them onto a conveyor. The clerk picks up one item at a time and interrogates it with a laser to read the barcode. Once identified and if sense prevails, similar goods are collected together e.g. fruit and vegetables go into one shopping bag and household goods into another. Now picture in your mind the whole process automated; replace shopping with biological cells; and substitute the barcode with cellular markers – welcome to the world of flow cytometry and cell sorting! We aim to give you a basic overview of all the important facets of flow cytometry without delving too deeply into the complex mathematics and physics behind it all. For that there are other books (some recommended at the back). -
A Multicenter Analysis of Subjectivity of Indirect Immunofluorescence Test in Antinuclear Antibody Screening

Patients and methods: The ANA-IIF testing was carried out in a total of 600 sera and evaluated by four laboratories. The inter-center agreement rates were detected. The same results given by the four centers were accepted as gold standard and the predictive values of each center were calculated. Results: The inter-center agreement was reported for ANA-IIF test results from 392 of 600 (65.3%) sera, while 154 of 392 results were positive. Four study centers reported 213 (35.5%), 222 (37.0%), 266 (44.3%), and 361 (60.2%) positive test results, respectively. In terms of the patterns, the highest and lowest positive predictive values were 72.3% and 42.7%, respectively, while the highest and lowest negative predictive values were 99.6% and 61.5%, respectively. -

A Case of Igg/Iga Pemphigus Presenting Malar Rash-Like Erythema
164 Letters to the Editor A Case of IgG/IgA Pemphigus Presenting Malar Rash-like Erythema Satomi Hosoda1, Masayuki Suzuki1, Mayumi Komine1*, Satoru Murata1, Takashi Hashimoto2 and Mamitaro Ohtsuki1 Departments of Dermatology, 1Jichi Medical University, 3311-1 Yakushiji, Shimotsuke, Tochigi 329-0498 and 2Kurume University School of Medicine, and Kurume University Institute of Cutaneous Cell Biology, Fukuoka, Japan. *E-mail: [email protected] Accepted August 17, 2011. Pemphigus is an autoimmune mucocutaneous bullous disease characterized by auto-antibodies against cell surface antigens of epidermal keratinocytes. Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are the major subtypes. Several other variants have been proposed, in- cluding pemphigus erythematosus, pemphigus vegetans, pemphigus herpetiformis (PH), and paraneoplastic pem- phigus. Deposition of IgG on epidermal keratinocyte cell surfaces and circulating anti-cell surface antibodies are characteristic in pemphigus. Cases involving IgA depo- sition on epidermal keratinocyte cell surfaces have been reported as IgA pemphigus. IgA pemphigus is divided into 4 subgroups based on clinical manifestation: subcorneal pustular dermatosis type, intraepidermal neutrophilic IgA dermatosis type, pemphigus foliaceus type, and pemphi- gus vulgaris type. Cases involving deposition of both IgG and IgA on keratinocyte cell surfaces have been reported (1–13). Some authors describe them as IgG/IgA pemphi- gus (1). Seventeen such cases have been reported so far, and heterogeneity of clinical features and target antigen has been detected in this group of pemphigus. Fig. 1.

Comparison of Histopathology, Immunofluorescence, and Serology

When antibody capture is utilized, this is referred to several different diagnostic methods. These include histopathology, as “sandwich ELISA” because the target antigen is bound between the direct immunofluorescence (DIF), indirect immunofluorescence immobilizing antibody and the primary antibody. Primary antibodies (IIF), enzyme-linked immunosorbent assay (ELISA) and are present in the patient’s serum. Enzyme-linked secondary antibodies immunoblotting.

Penyakit ini juga dikenal sebagai bagian dari skleroderma terlokalisir. Berdasarkan gambaran klinis dan kedalaman jaringan yang terlibat, morfea dikelompokkan ke dalam beberapa bentuk dan sekitar dua pertiga orang dewasa dengan morfea mempunyai tipe plak. Produksi kolagen yang berlebihan oleh fibroblast merupakan penyebab kelainan pada morfea dan mekanisme terjadinya aktivitas fibroblast yang berlebihan ini masih belum diketahui, meskipun beberapa mekanisme pernah diajukan. Morfe tipe plak biasanya bersifat ringan dan dapat sembuh dengan sendirinya. Morfea tipe plak yang penampilan klinisnya menyerupai lupus eritematosus sistemik, misalnya meliputi alopesia dan ulkus mukosa di mulut, jarang dijumpai. Sebuah kasus morfea tipe plak pada wanita berusia 20 tahun dibahas. Pasien ini diobati dengan imunosupresan dan antioksidan local maupun sistemik. Kondisi paisen membaik tanpa disertai efek samping yang berarti. Kata kunci: morfea, tipe plak. ABSTRACT Morphea is an uncommon connective tissue disease with the most prominent feature being thickening or fibrosis of the dermal without internal organ involvement. It is also known as a part of localized scleroderma. Based on clinical presentation and depth of tissue involvement, morphea is classified into several forms, and about two thirds of adults with morphea have plaque type. -

Exacerbation of Galli-Galli Disease Following Dialysis Treatment: a Case Report and Review of Aggravating Factors
Open Access Case Report DOI: 10.7759/cureus.15401 Exacerbation of Galli-Galli Disease Following Dialysis Treatment: A Case Report and Review of Aggravating Factors Tejas P. Joshi 1 , Sally Shaver 2 , Jaime Tschen 3 1. Dermatology, Baylor College of Medicine, Houston, USA 2. Dermatology, Conroe Dermatology Associates, Conroe, USA 3. Dermatology, St. Joseph Dermatopathology, Houston, USA Corresponding author: Tejas P. Joshi, [email protected] Abstract Galli-Galli disease (GGD) is a rare genodermatosis that is an acantholytic variant of Dowling-Degos disease that presents as lentigo-like macules/papules with progressive reticulated hyperpigmentation. Heat, sweat, ultraviolet light exposure, and topical retinoids have been reported to exacerbate the lesions associated with GGD. Here, we present a 77-year-old woman with end-stage renal disease and GGD who reported a worsening of lesions during the summer months and following hemodialysis treatment. Despite the severity of her lesions following dialysis, she refused treatment with isotretinoin out of concern for its side effect profile. In this case report, we discuss some available treatment options for GGD and review the exacerbating factors for GGD currently reported in the literature. Categories: Dermatology Keywords: galli-galli disease, dowling-degos disease, genodermatosis, dialysis, contact dermatitis, end-stage renal disease Introduction Galli-Galli disease (GGD) is a rare, autosomal dominant genodermatosis that is an acantholytic variant of Dowling-Degos disease (DDD). DDD encompasses a spectrum of skin conditions that present with progressive reticulated hyperpigmentation; while GGD was initially postulated to be a distinct entity from DDD, more recent evidence has led to the consensus that GGD is a variant of DDD [1]. -
