Vigabatrin-associated brain magnetic resonance imaging abnormalities and clinical symptoms in infants with tuberous sclerosis complex.

Objective: Previous retrospective studies have reported vigabatrin-associated brain abnormalities on magnetic resonance imaging (VABAM), although clinical impact is unknown. We evaluated the association between vigabatrin and predefined brain magnetic resonance imaging (MRI) changes in a large homogenous tuberous sclerosis complex (TSC) cohort and assessed to what extent VABAM-related symptoms were reported in TSC infants.

Methods: The Dutch TSC Registry and the EPISTOP cohort provided retrospective and prospective data from 80 TSC patients treated with vigabatrin (VGB) before the age of 2 years and 23 TSC patients without VGB.

Feline sarcoptic mange in Poland: A case series of three cats.

Background: Sarcoptic mange is rare in cats. The main symptoms reported in cases of feline sarcoptic mange include crusty lesions and pruritus, although these may vary in severity among individuals.

Objectives: This report describes three cats infested with Sarcoptes scabiei, all presenting with pruritus and excoriation.

Ongoing shuffling of protein fragments diversifies core viral functions linked to interactions with bacterial hosts.

Biological modularity enhances evolutionary adaptability. This principle is vividly exemplified by bacterial viruses (phages), which display extensive genomic modularity. Phage genomes are composed of independent functional modules that evolve separately and recombine in various configurations.

Comment on: Occurrence of Hookworm and the First Molecular and Morphometric Identification of Uncinaria stenocephala in Dogs in Central Europe.

Background: Hookworms are blood-feeding nematodes that infect millions of people and animals worldwide. The most common species infecting dogs in Europe are representatives of the family Ancylostomatidae, which differ in invasiology, biology and morphological features. However, the differentiation of invasions of species such as Uncinaria stenocephala and Ancylostoma caninum based on a coproscopic examination is problematic.
