Frontal fibrosing alopecia presenting with components of Piccardi-Lassueur-Graham-Little syndrome
No full textFrontal fibrosing alopecia (FFA), a cicatricial alopecia of the frontoparietal hairline affecting mainly postmenopausal women, is commonly associated with nonscarring alopecia of the eyebrows. This association has led some authors to relate it to Piccardi-Lassueur-Graham-Little syndrome (PLGLS), which is characterized by the triad of multifocal scalp cicatricial alopecia, nonscarring alopecia of the axillae and-or groin, and keratotic follicular papules. This is in spite of the absence of the follicular keratotic papules typical of PLGLS, and the different patterns of the cicatricial alopecias. We report a 37-year-old premenopausal woman with FFA associated with nonscarring alopecia of the eyebrows and axillae and follicular lichen planus-like lesions of the face. This case illustrates that FFA and PLGLS may share characteristics that, in addition to the overlap between FFA and PLGLS reported in the literature, would suggest they may be phenotypically related. © 2007 American Academy of Dermatology, Inc.Bardazzi F, 1999, ACTA DERM-VENEREOL, V79, P93; Bianchi L, 2001, CLIN EXP DERMATOL, V26, P518, DOI 10.1046-j.1365-2230.2001.00881.x; Martinez FC, 1999, BRIT J DERMATOL, V140, P1181; Chieregato C, 2003, INT J DERMATOL, V42, P342, DOI 10.1046-j.1365-4362.2003.01695.x; Dawn G, 2003, CLIN EXP DERMATOL, V28, P43, DOI 10.1046-j.1365-2230.2003.01140.x; Faulkner Catherine F, 2002, Australas J Dermatol, V43, P65, DOI 10.1046-j.1440-0960.2002.00558.x; Ghislain PD, 2003, DERMATOLOGY, V206, P391, DOI 10.1159-000069966; Gutierrez JV, 2004, J EUR ACAD DERMATOL, V18, P463, DOI 10.1111-j.1468-3083.2004-00945.x; Jumez N, 2005, ANN DERMATOL VENER, V132, P263, DOI 10.1016-S0151-9638(05)79259-0; KOSSARD S, 1994, ARCH DERMATOL, V130, P770, DOI 10.1001-archderm.130.6.770; Kossard S, 1997, J AM ACAD DERMATOL, V36, P59, DOI 10.1016-S0190-9622(97)70326-8; Lee WS, 1997, CUTIS, V60, P299; MATTA M, 1990, J AM ACAD DERMATOL, V22, P594, DOI 10.1016-0190-9622(90)70078-V; MEHREGAN DA, 1992, J AM ACAD DERMATOL, V27, P935, DOI 10.1016-0190-9622(92)70290-V; Mirmirani P, 2005, J AM ACAD DERMATOL, V52, P637, DOI 10.1016-j.jaad.2004.07.069; Moreno-Ramirez D, 2005, J EUR ACAD DERMATOL, V19, P700, DOI 10.1111-j.1468-3083.2005.01291.x; Tosti A, 2005, J AM ACAD DERMATOL, V52, P55, DOI 10.1016-j.jaad.2004.05.014; Trueb RM, 1998, HAUTARZT, V49, P388, DOI 10.1007-s001050050760; Viglizzo G, 2004, DERMATOLOGY, V208, P142, DOI 10.1159-000076489; WALSH SRA, GRAHAM LITTLE PICCAR20121
Takayasu disease presenting as malignant pyoderma gangrenosum in a child with relapsing polychondritis
No full textA 7-year-old Lebanese girl with recently diagnosed relapsing polychondritis had a 1-month history of several painful ulcerations involving her entire body. Skin biopsy was consistent with the diagnosis of pyoderma gangrenosum. She was hospitalized and started on intravenous steroids with partial improvement. During her hospital stay, she developed right wrist drop. Radiologic studies revealed a large aortic aneurysm and an axillary aneurysm compressing the right brachial nerve plexus. Pathology of the resected aortic anyeurism confirmed the diagnosis of Takayasu's arteritis. The patient was started on infliximab therapy with complete resolution of her skin lesions and improvement in hand function. © 2008 American Academy of Dermatology, Inc.Aoussar A, 2007, ANN DERMATOL VENER, V134, P264, DOI 10.1016-S0151-9638(07)91510-0; Barretto SN, 2002, MAYO CLIN PROC, V77, P971; Bell D, 2007, PLAST RECONSTR SURG, V120, P1087, DOI 10.1097-01.prs.0000278184.60488.8e; Brooklyn TN, 2006, GUT, V55, P505, DOI 10.1136-gut.2005.074815; Cazabon S, 2005, EYE, V19, P222, DOI 10.1038-sj.eye.6701457; Fearfield LA, 1999, BRIT J DERMATOL, V141, P339; Hewitt D, 2007, AUSTRALAS J DERMATOL, V48, P95, DOI 10.1111-j.1440-0960.2007.00344.x; Hoffman GS, 2004, ARTHRITIS RHEUM, V50, P2296, DOI 10.1002-art.20300; Hubbard VG, 2005, BRIT J DERMATOL, V152, P1059, DOI 10.1111-J.1365-2133.2005.06467.x; Jolly M, 2005, JCR-J CLIN RHEUMATOL, V11, P213, DOI 10.1097-01.rhu.0000173218.28013.3e; Kanemitsu S, 2005, ANN THORAC SURG, V80, P1914, DOI 10.1016-j.athoracsur.2004.06.098; Karageorgaki ZT, 2007, CLIN RHEUMATOL, V26, P984, DOI 10.1007-s10067-006-0227-0; Letko E, 2002, SEMIN ARTHRITIS RHEU, V31, P384, DOI 10.1053-sarh.2002.32586; MCADAM LP, 1976, MEDICINE, V55, P193, DOI 10.1097-00005792-197605000-00001; Monsel G, 2007, ANN DERMATOL VENER, V134, P552; Moroki N, 1979, Nihon Naika Gakkai Zasshi, V68, P1133; Mpofu S, 2003, RHEUMATOLOGY, V42, P1117, DOI 10.1093-rheumatology-keg280; Piette JC, 1999, ANN RHEUM DIS, V58, P656, DOI 10.1136-ard.58.10.656; PRESMANES MM, 2001, ACTA DERMOSIFILIOGR, V92, P596; Rapini RP, 2006, CLIN DERMATOL, V24, P482, DOI 10.1016-j.clindermatol.2006.07.018; Rho YH, 2005, J RHEUMATOL, V32, P954; Richez C, 2004, CLIN EXP RHEUMATOL, V22, P629; Saadoun D, 2003, J RHEUMATOL, V30, P1394; Sapienza MS, 2004, DIGEST DIS SCI, V49, P1454, DOI 10.1023-B:DDAS.0000042245.20042.4f; Sasirekha D, 2006, J Assoc Physicians India, V54, P817; Selim AGA, 2001, J CLIN PATHOL, V54, P890; Swale VJ, 2005, CLIN EXP DERMATOL, V30, P134, DOI 10.1111-j.1365-2230.2004.01681.x; Tanaka F, 2006, INTERNAL MED, V45, P313, DOI 10.2169-internalmedicine.45.1377; Ujiie H, 2004, CLIN EXP DERMATOL, V29, P357, DOI 10.1111-j.1365-2230.2004.01514.x; Vounotrypidis P, 2006, RHEUMATOLOGY, V45, P491, DOI 10.1093-rheumatology-kel04185

Multi-Task Learning For Option Pricing
No full textMulti-task learning is a process used to learn domain-specific bias. It consists in simultaneously training models on different tasks derived from the same domain and forcing them to exchange domain information. This transfer of knowledge is performed by imposing constraints on the parameters defining the models and can lead to improved generalization performance. In this paper, we explore a particular multi-task learning method that forces the parameters of the models to lie on an affine manifold defined in parameter space and embedding domain information. We apply this method to the prediction of the prices of call options on the S&P index for a period of time ranging from 1987 to 1993. An analysis of variance of the results is presented that shows significant improvements of the generalization performance. L'apprentissage multi-tâches est une manière d'apprendre des particularités d'un domaine (le biais) qui comprend plusieurs tâches possibles. On entraîne simultanément plusieurs modèles, un par tâche, en imposant des contraintes sur les paramètres de manière à capturer ce qui est en commun entre les tâches, afin d'obtenir une meilleure généralisation sur chaque tâche, et pour pouvoir rapidement généraliser (avec peu d'exemples) sur une nouvelle tâche provenant du même domaine. Ici cette commonalité est définie par une variété affine dans l'espace des paramètres. Dans cet article, nous appliquons ces méthodes à la prédiction du prix d'options d'achat de l'indice S&P 500 entre 1987 et 1993. Une analyse de la variance des résultats est présentée, démontrant des améliorations significatives de la prédiction hors-échantillon.option call pricing, multi-task learning, artificial neural networks, valorisation d'options d'achat, apprentissage multi-tâches, réseau de neurones artificiels
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Retronychia: Report of two cases
No full textRetronychia is an incomplete form of nail shedding that leads to embedding of the nail into the proximal nail fold and subsequent inflammation. Patients present with persistent paronychia in the setting of disrupted nail growth. Other nail changes may be present. Simple avulsion is curative, and unlike other forms of ingrown nails, it does not tend to recur. We report 2 cases of retronychia that were associated with distal onycholysis and subungual hematoma, respectively. Both were successfully treated with nail avulsion. © 2008 American Academy of Dermatology, Inc.BARAN R, 2001, DIS NAILS THEIR MANA, P74; Betti R, 2000, EUR J DERMATOL, V10, P149; de Berker DA, 1999, J EUR ACAD DERMATOL, V12, pS126; FILLOUX J F, 1991, Annales de Chirurgie de la Main et du Membre Superieur, V10, P181, DOI 10.1016-S0753-9053(05)80210-8; LOVETT JE, 1995, ANN PLAS SURG, V34, P84, DOI 10.1097-00000637-199501000-00018; MIKHAIL GR, 1984, J AM ACAD DERMATOL, V11, P291, DOI 10.1016-S0190-9622(84)70165-4; WAWROSCH W, 1985, HAUTARZT, V36, P16815111
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
