A venous anastomotic network is occasionally found at the base of the brain, which closely resembles the vicinal arterial circle of Willis. When present, this venous polygon is composed of the anterior cerebral and communicating veins, the basal vein of Rosenthal and the posterior communicating and lateral mesencephali…

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) belong to most frequently used drugs worldwide. NSAIDs belong to the family of drugs that represent the biggest drug risk as to the number of adverse drug reactions (ADRs), as well as to the number of deregistered drugs. METHODS: We analysed the whole consumpt…

Most of medical journals now has it's electronic version, available over public networks. Although there are parallel printed and electronic versions, and one other form need not to be simultaneously published. Electronic version of a journal can be published a few weeks before the printed form and must not has identic…

High Impedance Surfaces (HIS) have recently shown the ability to support leaky waves, and to excite plasmonic and HIS resonance frequency modes for use as an antenna. In this paper, we analyzed, designed, and fabricated a true metasurface antenna (TMA) by directly feeding edge-located HIS cells through a microstrip fee…

Discovery of essential genes in pathogenic organisms is an important step in the development of new medication. Despite a growing number of genome data available, little is known about C. albicans, a major fungal pathogen. Most of the human population carries C. albicans as commensal, but it can cause systemic infectio…

A 73-year old man presented with the tinnitus in the left ear for 11 months. Computer tomography (CT) showed an enlarged dolichoectasia of the left vertebral artery. Magnetic resonance imaging (MRI) of the brain shows dolichoectasia of the left vertebral artery and the initial part of the basilar artery. Multi-slices c…

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…

BACKGROUND: The purpose of the study was to evaluate the utility of fine needle aspiration--FNA and cytologic analysis of impalpable complicated breast cysts. MATERIAL AND METHODS: We rewieved the imaging findings, aspiration, cytology and biopsy results and followup imaging findings of 246 complicated cysts in 166 wo…

In the present case, ultrasound examination ruled out the presence of hematosalpinx or other gynecological tumors. This was of great importance to the surgical intervention, especially for avoiding laparotomy. Dilatation of the vagina and uterus, due to imperforate hymen with retrograde menstruation should be considere…

Hobnail hemangioma (HH) was known in the past as targetoid hemosiderotic hemangioma (THH). We present a case that meets the criteria of HH in a 34-year-old woman. The lesion presented as a reddish papule on her left hip. It changed periodically during menstruation and the changes included. The biopsy showed the charact…

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: Biological data have traditionally been stored and made publicly available through a variety of on-line databases, whereas biological knowledge has traditionally been found in the printed literature. With journals now on-line and providing an increasing amount of open access content, often free of copyright…

BACKGROUND: Oral hygiene is of paramount importance for the preservation of oral health, and for patients affected by periodontal disease establishing an effective oral hygiene routine is the first step of therapy. Several clinical frameworks have been developed to foster behavior change, such as motivational interview…

Abnormal peritoneal folds near the liver are very rare. This case report presents an observation of an abnormal fold of peritoneum that extended from the upper right part of the greater omentum and stomach to the fossa for gallbladder. This fold merged with the lesser omentum on the left and extended to the right kidne…

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…

Accurate delineation of cervical cancer clinical target volume (CTV) remains labor-intensive and variable. This retrospective single-center study internally evaluated a SAM-Med3D baseline initialized from public pretrained weights and fine-tuned on the study training cohort for prompted cervical cancer CTV segmentation…

Data sharing between technology companies and academic health researchers has multiple health care, scientific, social, and business benefits. Many companies remain wary about such sharing because of unaddressed concerns about ethics, data security, logistics, and public relations. Without guidance on these issues, few…

We designed and implemented a generic search engine (Vaidurya), as part of our Digital clinical-Guideline Library (DeGeL) framework. Two search methods were implemented in addition to full-text search: (1) concept-based search, which relies on pre-indexing the guidelines in a clinically meaningful fashion, and (2) cont…

Large language models (LLMs) are increasingly being evaluated for radiology reporting. However, the incremental value of adding report-embedded key images to report text for breast ultrasound report auditing remains unclear. This retrospective study included 818 breast ultrasound examinations with pathology- or follow-…
