A case of tinea incognito mimicking subcorneal pustular dermatosis

An 89-year-old woman presented with plaque-like lesions, accompanied with pustules and desquamation on the back and front of the trunk for approximately one year. Long term use of potent topical corticosteroids was ineffective. Because of the chronicity of her condition, the diagnoses of subcorneal dermatosis or subcorneal pustular dermatosis type of IgA pemphigus were considered. However, fungal hyphae were observed in the potassium hydroxide examination. Therefore, we present this case since this clinical appearance of tinea incognito can also mimic various pustular dermatoses

Optimizing fire station locations for the Istanbul metropolitan municipality

Copyright @ 2013 INFORMSThe Istanbul Metropolitan Municipality (IMM) seeks to determine locations for additional fire stations to build in Istanbul; its objective is to make residences and historic sites reachable by emergency vehicles within five minutes of a fire station’s receipt of a service request. In this paper, we discuss our development of a mathematical model to aid IMM in determining these locations by using data retrieved from its fire incident records. We use a geographic information system to implement the model on Istanbul’s road network, and solve two location models—set-covering and maximal-covering—as what-if scenarios. We discuss 10 scenarios, including the situation that existed when we initiated the project and the scenario that IMM implemented. The scenario implemented increases the city’s fire station coverage from 58.6 percent to 85.9 percent, based on a five-minute response time, with an implementation plan that spans three years

Perspective of turkish medicine students on cancer, cancer treatments, palliative care, and oncologists (ares study): A study of the palliative care working committee of the turkish oncology group (TOG)

Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913–2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15–iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840–841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words “cancer” and “oncologist” meant for the students. The participant students were analyzed in two study groups; “group 1” (n = 1.255) were phases I and II students that had never attended an oncology lesson, and “group 2” (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of “death” (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students’ understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country. © 2018, American Association for Cancer Education

Influence of the gut microbiome on IgE and non-IgE-mediated food allergies

Congress of the European-Academy-of-Allergy-and-Clinical-Immunology (EAACI) -- MAY 26-30, 2018 -- Munich, GERMANYWOS: 000441690400204Background: The prevalence of food allergy (FA) in children has been increasing in last decade. Recent studies show changes in gut microbiome with FA. However, whether gut microbiome may differ between IgE and non‐IgE‐mediated FA is not defined. The aim of this study is to examine the intestinal microbiome composition in infants with IgE and non‐IgE‐mediated FA and healthy infants. Method: Infants younger than 1‐year‐old, breastfed and diagnosed with FA by a physician were included in the study. DNA was isolated from stool samples of infants with non‐IgE‐mediated FA (n = 25) and IgE‐mediated FA (n = 11) and healthy infants (n = 7). Whole genome shotgun sequencing was applied to identify the composition of microbial DNA (an average depth of 3.1 ± 0.8 million paired end reads and 0.9 ± 0.2 gigabase pairs). Results: There were compositional differences among 3 different groups. Shannon index was significantly higher in IgE‐mediated FA compared to non‐IgE‐mediated FA group (Kruskal‐Wallis test, P = 0.034). Even though β‐diversity was similar, the Sparse Partial Least Square Discriminant Analysis (sPLS‐DA) demonstrated that there were taxa‐level differences among three groups. In species level, Veillonella parvula was in a significantly higher density in healthy infants compared to IgE and non‐IgE‐mediated FA groups. Rahnella aquatilis and Lactobacillus salivarius were significantly lower and Treponema succinifaciens significantly higher in IgE‐mediated FA group compared to other groups. Additionally, Prevotella sp. oral taxon 299 was significantly lower in non‐IgE‐mediated FA group compared to others. Prevotella sp oral taxon 299 was related to mucus in stool whereas urticaria related species were Olsenall uli, Bactreoides thetaiotaomicron, Klebsiella variiocola, Rahnella aquatilis, Treponema succinfaciens, Ethanoligenens harbinenese. Conclusion: Analysis of microbiome differences in FA patients may aid in the understanding of the disease process. The present data suggest that there are compositional variations mostly in species‐ level among infants with FA and healthy ones. Our results suggest that the gut microbiome has a stronger relationship to IgE‐mediated than non‐IgE‐mediated FA. Further functional analysis of the microbiome may help better understand the changes seen in the gut microbiome in FAs and improve our knowledge in the disease etiopathology.European Academy of Allergy and Clinical Immunolog

Investigation of the PD-1/PD-L1 Expression in the Lesional Skins of Patients with Psoriasis

Introduction: Psoriasis is an immune-mediated, chronic and inflammatory disease whose pathogenesis is affected by the interactions of several immune cells and cytokines. PD-1 is an inhibitor receptor that is expressed to a large extent in T lymphocytes and responsible for regulating autoimmunity and self-tolerance. Objectives: In this study, we aimed to investigate the expression of PD-1/PD-L molecules in the lesioned skins of psoriasis patients. Methods: The study included 30 psoriasis patients, and 15 healthy volunteers as the control group. Anti PD-1 and PD-L1 antibodies were applied to the skin biopsy samples that were collected from the patient and control groups. Cytoplasmic and membranous staining of PD-1 and PD-L1 were considered positive. The number of stained immune cells that was examined for each case. Results: The percentage of the tissues with high PD-1 (+) and PDL-1 (+) immune cell counts were significantly higher in the psoriasis patients compared to healthy controls (P values = 0.004 and 0.002, respectively). A negative and statistically significant correlation was detected between PDL-1(+) immune cell numbers and PASI scores (P = 0.033, r=-0.57). Conclusions: In the lesioned skin samples of psoriasis patients, the PD-1 and PD-L1 expressions were significantly higher in immune cells than that in the skin samples of the healthy controls. This study was the first investigation of the expression of PD-1/PD-L molecules in the immune cells in found the lesioned skins of psoriasis patients

Seismic performance evaluation of traditional timber Hımış frames: capacity spectrum method based assessment

Timber constructions have been widely suggested to be seismically resistant based on post-disaster reconnaissance studies. This observation has, however, remained to a large extent anecdotal due to the lack of experimental work supporting it, especially for certain timber architectural forms, including traditional timber frame “hımış” structures. To fill this gap, the authors carried out an extensive full-scale testing scheme using frames of various geometrical configurations, tested under reverse-cyclic lateral loading with/without infill (brick and adobe) or cladding (bağdadi and şamdolma) (Aktas et al. in Earthq Spectra 30(4):1711–1732, 2014a, b). The tests concluded that hımış frames had high energy dissipation capabilities due mostly to nailed connections. Infill/cladding significantly helped improve stiffness and lateral load strength of the frames, and timber type did not seem to make a remarkable impact on the overall behaviour. The current paper, on the other hand, uses test data to calculate capacity/demand ratios based on capacity spectrum method and Eurocode 8 to elaborate more on the performance of “hımış” structures under seismic loading. The obtained results are discussed to draw important conclusions with regards to how frame geometry and infill/cladding techniques affect the overall performance
