The authors describe a case of recurrent malignant epitheloid schwannoma of the lower lip. Histologically, the tumor was composed of fibroblast-like spindle cells in compact fascicles and areas of epitheloid growth, combined with demonstration of S-100, GFAP and NF positivity, which is characteristic for this type of t…

The aim of our study was to optimise current therapy of gastric tumours. The studied population consisted of 92 patients treated at the 1st Department of Surgery, St. Anne's Teaching Hospital, Brno, Czech Republic, and at the Department of Radiation Oncology of the same hospital during 1994-2000. We have proven that, n…

Automated condition monitoring of railway switches and crossings (S&C) requires classification models whose reported accuracy reflects genuine generalization rather than evaluation artefacts. This paper presents a methodologically rigorous, leak-free machine-learning framework for vibration-based event classification,…

BACKGROUND: In an attempt to identify motivating factors involved in decisions to publish in open access and open archives (OA) journals, individual interviews with biomedical faculty members at the University of North Carolina at Chapel Hill (UNC-Chapel Hill) and Duke University, two major research universities, were…

We present the case of a 75-year-old man who was diagnosed with Degos disease (DD) in the context of type 2 diabetes mellitus. The cutaneous lesions of DD were located at the trunk as well as in the proximal parts of the arms. He presented with positive laboratory test for lupic anticoagulant, but other rheumatologic p…

OBJECTIVES: Authors evaluate diagnosis, surgery and results in the implantees with malformed inner ear. METHODS: Four children with the inner ear malformations were included in this series (one child with common cavity, two children with narrow internal auditory meatus and one child with lateral semicircular canal apl…

BACKGROUND: The aim of this investigation was to systematically review the current literature to provide the best data for indications, outcomes, survival, and complication rates of pedicled propeller perforator flaps for upper body defects. METHODS: A comprehensive literature review for articles published from Januar…

OBJECTIVE: To describe how Spanish-speaking biomedical professionals in Latin America access and utilize bibliographic databases. METHODS: Based on a MEDLINE search, 2 515 articles published between August 2002 and August 2003 were identified that dealt with and/or had authors from 16 countries: Argentina, Bolivia, Ch…

AIM: The objectives of this study were to: determine the presentation to publication conversion rate (PPCR) in peer-reviewed indexed journals of free papers and posters presented at 12-14th September 2001 British Orthopaedic Association (BOA) annual meeting and to compare the publication rate with the American Academy…

BACKGROUND: Accurate injury cause data are essential for injury prevention research. U.S. military hospitals, unlike civilian hospitals, use the NATO STANAG system for cause-of-injury coding. Reported deficiencies in civilian injury cause data suggested a need to specifically evaluate the STANAG. METHODS: The Total Ar…

BACKGROUND: Formal, structured annual appraisals are now a regulatory requirement for all doctors and must meet the standards stipulated by the General Medical Council (GMC), including connection with a designated body. AIMS: To investigate occupational physicians' opinions and experience of the first year of appraisa…

Liposarcoma is a malignancy of fat cells that occurs in deep soft tissue and mostly seen in limbs and retroperitoneum. It is the most common mesenchymal tumor of the retroperitoneum. It is detected at very late stages especially when the tumor gains substantial size, weight of several pounds at the time of diagnosis be…

BACKGROUND: Communication plays a central role in accessing healthcare, but few studies have investigated how language shapes the full continuum of access, from perceptions of the system to experiences of care. We sought to clarify how preferred language for healthcare services differentiates patterns of episodic virtu…

CONTEXT: Independent validation of published scientific results through study replication is a pre-condition for accepting the validity of such results. In computation research, full replication is often unrealistic for independent results validation, therefore, study reproduction has been justified as the minimum acce…

The free availability of full-text veterinary publications in MEDLINE-indexed journals by US and Canadian veterinary faculty from 2006-7 was determined. Additionally, publishing databases were searched to obtain general statistics on veterinary publishing. A survey of institutional initiatives to promote open-access jo…

Neurocysticercosis (cysticercosis cerebri) is a rare neurological diagnosis in Croatia. It is classically divided into four types: intraparenchymal, basilar cisternal, ventricular and diffuse. Computerized tomography (CT) and magnetic resonance imaging (MRI) established the diagnosis by demonstrating cysticercosis diss…

The aim of the present study was to define more accurately the necessary health care in patients with the primary Sjogren's syndrome and to compare it to those necessary for patients with another autoimmune disease--rheumatoid arthritis without a concomitant Sjogren's syndrome (Tab. 1, Ref. 5).
