Mannose-Binding Lectin 2 (MBL2) combined genotypes deficiency is associated with susceptibility for Oral Lichen Planus.

Genet Mol Biol 2019 Feb 21. Epub 2019 Feb 21.

Department of Surgical, Medical and Health Sciences, University of Trieste, Trieste, Italy.

Oral Lichen Planus (OLP) is an oral inflammatory condition, mediated by host immune system reaction, presenting basal membrane damages with inflammatory lesions in the mouth and/or skin. In this study, the role of functional polymorphisms in the MBL2 gene, encoding for Mannose-Binding Protein C (MBP-C), a member of the innate immune response and an acute-phase protein able to activate the complement cascade, was investigated to assess a possible association with OLP susceptibility in Italian patients. Two variations at the promoter region (called H/L and X/Y) and three at the first exon (at codon 52, 54, and 57) of the MBL2 gene were analyzed in 69 OLP patients and 244 healthy controls from northeastern Italy.

Portable system for Time-Domain Diffuse Correlation Spectroscopy.

IEEE Trans Biomed Eng 2019 Feb 15. Epub 2019 Feb 15.

We introduce a portable system for clinical studies based on Time-Domain Diffuse Correlation Spectroscopy (TD-DCS). After evaluating different lasers and detectors, the final system is based on a pulsed laser with about 550 picosecond (ps) pulse width and a coherence length of 38 mm, and two types of single-photon avalanche diodes (SPAD). The higher efficiency of the red-enhanced SPAD maximizes detection of the collected light, increasing the signal-to-noise ratio, while the better timing response of the CMOS SPAD optimizes the selection of late photons and increases spatial resolution.

Linear porokeratosis associated with Bardet-Biedl syndrome: A case report.

Pediatr Dermatol 2019 Feb 22. Epub 2019 Feb 22.

Department of Dermatology, University of Virginia Health System, Charlottesville, Virginia.

This case report presents a 17-year-old boy with Bardet-Biedl syndrome (BBS) and a long-standing hyperpigmented eruption on the left trunk and upper extremity, clinically and histologically consistent with linear porokeratosis (LP). BBS patients frequently require solid organ transplant, and subsequent immunosuppression places them at especially high risk for malignant transformation of premalignant skin lesions such as LP. Although BBS affects multiple organ systems, there are only a handful of case reports detailing associated cutaneous involvement, and, to our knowledge, this is the first reported case of linear porokeratosis occurring in patient with BBS.

Retrospective Identification of a Broad IgG Repertoire Differentiating Patients With Skin and Soft Tissue Infections From Controls.

Front Immunol 2019 7;10:114. Epub 2019 Feb 7.

Department of Medicine, University of Pennsylvania, Philadelphia, PA, United States.

Although the relevance of humoral immunity for protection against skin and soft tissue infections (SSTIs) has been suggested by several animal and human studies, the question of which human antibodies may be protective has so far impeded the development of a safe and effective vaccine. Because most adults have developed certain anti- antibodies due to colonization or infection, we hypothesized that the titers of antibodies to in uninfected controls would differ from those in infected patients and would also differ in infected patients from the time of acute infection to a 40-day convalescent serum. To test these hypotheses, we measured human antibody levels against a panel of 134 unique antigens comprising the surfome and secretome in subjects with active culture-confirmed SSTIs (cases) and in controls with no infection, using a novel protein microarray.

Herpes Virus Reactivation in Astronauts During Spaceflight and Its Application on Earth.

Front Microbiol 2019 7;10:16. Epub 2019 Feb 7.

Jes Tech, KBR Wyle Laboratories Houston, Houston, TX, United States.

Latent herpes virus reactivation has been demonstrated in astronauts during shuttle (10-16 days) and International Space Station (≥180 days) flights. Following reactivation, viruses are shed in the body fluids of astronauts. Typically, shedding of viral DNA is asymptomatic in astronauts regardless of mission duration; however, in some cases, live/infectious virus was recovered by tissue culture that was associated with atopic-dermatitis or skin lesions during and after spaceflight.

Neurocutaneous Melanosis in Association With Large Congenital Melanocytic Nevi in Children: A Report of 2 Cases With Clinical, Radiological, and Pathogenetic Evaluation.

Front Neurol 2019 7;10:79. Epub 2019 Feb 7.

Department of Pediatrics, Shinshu University School of Medicine, Matsumoto, Japan.

Melanocytic nevi present at birth, or within the first few months of life, are defined as congenital melanocytic nevi (CMN). Neurocutaneous melanosis (NCM) is a rare disorder, represents pigment cell tumors of the leptomeninges, and occurs in association with large or multiple CMN. NCM carries an extremely poor prognosis.

Need for Flexible Adjustment of the Treatment Schedule for Aprepitant Administration against Erlotinib-Induced Refractory Pruritus and Skin Rush.

Case Rep Oncol 2019 Jan-Apr;12(1):84-90. Epub 2019 Jan 21.

Division of Medical Oncology, Department of Internal Medicine, Teikyo University School of Medicine, Tokyo, Japan.

Common dermatological side-effects associated with erlotinib, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), include pruritus and skin rash, which are mediated by substance P, leading to the occasional discontinuation of cancer treatment. Aprepitant is an antagonist of neurokinin-1 receptor, through which substance P activates the pruritogens. Thus, aprepitant is expected to offer a promising option for the treatment of erlotinib-induced pruritus. Read More

A Mosquito Bite with Devastating Complications in an Immunocompromised Patient.

Case Rep Oncol 2019 Jan-Apr;12(1):22-28. Epub 2019 Jan 4.

Klinik für Innere Medizin II, Hämatologie und internistische Onkologie, Universitätsklinikum Jena, Jena, Germany.

Infectious complications such as invasive aspergillosis or infection with (SM) in immunocompromised patients are associated with a high mortality rate. Our report concerns a 40-year-old male newly diagnosed very severe aplastic anemia (vSAA) who in consequence of a mosquito bite was suffering from skin lesion and consecutive soft tissue phlegmon subsequent to the administration of antithymocyte globulin; a full-thickness autologous meshed skin graft successfully performed to cover skin ulcera after allogeneic stem cell transplantation (SCT). This unusual case illustrates the importance of appropriate diagnosis, anti-infective therapy and close interdisciplinary diagnostic algorithms to minimalize side effects and the selection of resistant strains and to improve patients' outcome.

Superresolution microscopy reveals distinct localisation of full length IRSp53 and its I-BAR domain protein within filopodia.

Sci Rep 2019 Feb 21;9(1):2524. Epub 2019 Feb 21.

Institute of Medical Biology, A*STAR, Singapore, 138684, Singapore.

Superresolution microscopy offers the advantage of imaging biological structures within cells at the nano-scale. Here we apply two superresolution microscopy techniques, specifically 3D structured illumination microscopy (3D-SIM) and direct stochastic optical reconstruction microscopy (dSTORM), a type of single molecule localisation microscopy, to localise IRSp53 protein and its I-BAR domain in relation to F-actin within filopodia. IRSp53 generates dynamic (extending and retracting) filopodia 300 nm wide with a distinct gap between IRSp53 and F-actin. Read More
