Revolutionizing Digital Pathology With the Power of Generative Artificial Intelligence and Foundation Models.

Digital pathology has transformed the traditional pathology practice of analyzing tissue under a microscope into a computer vision workflow. Whole-slide imaging allows pathologists to view and analyze microscopic images on a computer monitor, enabling computational pathology. By leveraging artificial intelligence (AI) and machine learning (ML), computational pathology has emerged as a promising field in recent years.

Eigenvalue based spectral classification.

This paper describes a new method of classification based on spectral analysis. The motivations behind developing the new model were the failures of the classical spectral cluster analysis based on combinatorial and normalized Laplacian for a set of real-world datasets of textual documents. Reasons of the failures are analysed.

The Algorithm of Determining an Anti-Collision Manoeuvre Trajectory Based on the Interpolation of Ship's State Vector.

The determination of a ship's safe trajectory in collision situations at sea is one of the basic functions in autonomous navigation of ships. While planning a collision avoiding manoeuvre in open waters, the navigator has to take into account the ships manoeuvrability and hydrometeorological conditions. To this end, the ship's state vector is predicted-position coordinates, speed, heading, and other movement parameters-at fixed time intervals for different steering scenarios.

The article presents an original design of an expert system, whose function is to automatically stabilize ship's course. The focus is put on the inference engine, a mechanism that consists of two functional components. One is responsible for the construction of state space regions, implemented on the basis of properly processed signals recorded by sensors from the input and output of an object.

Cerebellar liponeurocytoma with atypical histological features - a rare example of a glioneuronal tumor.

We present a case of a rare neoplasm in a 77-year-old woman with previous oncological history, who developed a rapid onset of cerebellar symptoms. The neuroimaging detected a posterior fossa tumor suspected of meningioma which was completely resected soon after. Histologically the neoplasm had two components with different immunophenotype.

The Ship Movement Trajectory Prediction Algorithm Using Navigational Data Fusion.

It is essential for the marine navigator conducting maneuvers of his ship at sea to know future positions of himself and target ships in a specific time span to effectively solve collision situations. This article presents an algorithm of ship movement trajectory prediction, which, through data fusion, takes into account measurements of the ship's current position from a number of doubled autonomous devices. This increases the reliability and accuracy of prediction.

Seroprevalence of Bartonella Species in Patients with Ocular Inflammation.

Bartonella species, vector-borne etiologic agents of many systemic or self-limited infections, are responsible for a widening spectrum of diseases in humans, including inflammatory conditions of the eye. The aim of this study was to determine whether there is any relationship between uveitis and the evidence of Bartonella spp. infection in the serum, ocular fluid, and cataract mass in patients with intraocular inflammation.

The Impact of Short-Term, Intensive Antifolate Treatment (with Pyrimethamine and Sulfadoxine) and Antibiotics Followed by Long-Term, Secondary Antifolate Prophylaxis on the Rate of Toxoplasmic Retinochoroiditis Recurrence.

Purpose: To assess the impact of intensive antifolate treatment, followed by secondary antifolate prophylaxis (A-SP) on the recurrence rate of toxoplasmic retinochoroiditis (TRC). To investigate whether there are any other factors potentially predisposing for recurrence.

Material And Methods: A total of 637 medical records of TRC patients, who had been treated in the years 1994-2013 were reviewed.

[Unilateral optic disc oedema as a first sign of ocular toxoplasmosis – case report].

Management of toxoplasmic retinochoroiditis during pregnancy, postpartum period and lactation: clinical observations.

Background: During pregnancy and labor, the immune response is physiologically impaired and women are more susceptible to infections. Since many drugs may have potentially adverse effects on the fetus and newborn, less aggressive treatment regimens should be considered in pregnant and lactating patients. The aim of our study was to present the management of toxoplasmic retinochoroiditis during pregnancy, postpartum period, and lactation.

Do pregnancy, postpartum period and lactation predispose to recurrent toxoplasmic retinochoroiditis?

Background: The aim of the study was a statistical analysis of the possible effects of pregnancy, postpartum period, and lactation on increased risk for reactivation of toxoplasmic retinochoroiditis.

Material And Methods: A retrospective study was undertaken of the clinical records of 661 patients referred with the diagnosis of acute toxoplasmic retinochoroiditis to the Department of Zoonoses and Tropical Diseases, Medical University of Warsaw and to the Department of Ophthalmology, Medical University of Warsaw in the years 1994-2014. This group of inpatients consisted of 213 women of child-bearing age (18 to 40 years).

The first case of human autochtonous subconjunctival dirofilariosis in Poland and MALT lymphoma as possible consequence of this parasitosis.

The first case of human dirofilarosis in Poland was recorded in 2007. Until that time our country was free of Dirofilaria repens. Recent studies show that 21,4- 60% of dogs in Warsaw region harbour microfilariae, therefore it is becoming a growing problem in Central Europe.

Spotted fever rickettsiosis caused by Rickettsia raoultii--case report.

We report the case of rickettsial eschar-associated spotted fever, most probable due to Rickettsia raoultii, an emerging pathogen, which was previously described in patients with tick-borne lymphadenopathy (TIBOLA), also called Dermacentor-borne necrosis erythema and lymphadenopathy (DEBONEL). The pathogenicity of R. raoultii is not well established.

[Parasitophobic patient suffering from scabies treated with ivermectin--a case report].

We present a case of an atypical, difficult to diagnose crusted scabies caused by the invasion of non-human parasite (probably horse scabies Psoroptes equi) treated successfully by a rarely used in Europe antiparasitic agent-ivermectin. This inconvenient parasitemia additionally triggered parasitophobia--all of that together complicates the approach.

[Typhoid fever imported from the tropic in Poland].

We present three cases of typhoid fever imported to Poland from India in the beginning of the year 2006 treated in our Zoonosis and Tropical Medicine Department. Two of them, with mild course of the disease, were vaccinated with Typhim Vi vaccine, the third didn't obtain any, and had very heavy, almost classical course of the disease. All of them behaved in India in improper way, probably also because were convinced they were protected by the vaccine.
