Abstract The term oronasal fistula refers to an acquired communication between the oral and nasal cavities, and can result from several conditions. However, oronasal fistula formation has not yet been described to be associated with bacterial infections. We have described in this case report for the first time a rapidly forming oronasal fistula and severe lingual lesions in a dog, involving an infection with Streptococcus canis. The patient was a 9-year-old male intact Golden Retriever with a nonspecific history of depression, mild pyrexia, anorexia and retching lasting for two days. Within four days he developed an extensive oronasal fistula, several pseudomembranous erosions, ulcerations and necrotic areas of the tongue and bronchopneumonia. Histopathology of the tongue revealed severe multifocal necrotizing and suppurative subchronic inflammation. Streptococcus canis, Pasteurella multocida, and Staphylococcus pseudintermedius were isolated from the bronchoalveolar lavage and the oronasal fistula. Despite the treatment, the dog developed necrotizing fasciitis and the owners elected euthanasia.

Case summary A 10-year-old male neutered domestic shorthair cat was presented with a 4 month history of slow, progressive swelling and intermittent multifocal bleeding of the distal right forepaw that progressively developed after cephalic vein catheterisation for anaesthesia. The procedure was performed for dental calculus removal. Initial clinical and biopsy (superficial biopsy) findings matched two differential diagnoses: progressive angiomatosis and acquired peripheral arteriovenous fistula (AVF). AVF was suspected based on Doppler ultrasound examination that identified multiple abnormal sinusoidal neoformed branching vessels with turbulent high-velocity flow spectrum at the confluence of the artery and vein, and high-velocity arterialised flow in the vein. Owing to rapid and severe progression of lesions after biopsy, the owner requested amputation of the cat’s limb. A definitive diagnosis of acquired iatrogenic peripheral AVF was based on deep-tissue microscopical evaluation. High numbers of arterioles and venules in superficial and deep dermis embedded in oedematous stroma were connected to dilated and tortuous vessels with irregularly thickened walls in deep dermis and panniculus. Vasculitis and vascular thrombosis and thickening (attributed to local hypertension) were common findings. No bone or muscular invasion were observed. The cat was doing well 3 years after surgery. Relevance and novel information This report describes a case of iatrogenic acquired peripheral AVF following venous catheterisation in a cat, fully documented for the first time by a combination of clinical findings, ultrasound imaging, complete histopathology and follow-up history.

BackgroundThe prognostic impact of previous depression on myocardial infarction survival remains poorly understood.AimsTo examine the association between depression and all-cause mortality following myocardial infarction.MethodUsing Danish medical registries, we conducted a nationwide population-based cohort study. We included all patients with first-time myocardial infarction (1995–2014) and identified previous depression as either a depression diagnosis or use of antidepressants. We used Cox regression to compute adjusted mortality rate ratios (aMRRs) with 95% confidence intervals.ResultsWe identified 170 771 patients with first-time myocardial infarction. Patients with myocardial infarction and a previous depression diagnosis had higher 19-year mortality risks (87% v. 78%). The overall aMRR was 1.11 (95% CI 1.07–1.15) increasing to 1.22 (95% CI 1.17–1.27) when including use of antidepressants in the depression definition.ConclusionsA history of depression was associated with a moderately increased all-cause mortality following myocardial infarction.

ABSTRACT Twenty-five distinct tetracycline-resistant gram-negative bacteria recovered from four Chilean fish farms with no history of recent antibiotic use were examined for the presence of tetracycline resistance (tet) genes. Sixty percent of the isolates carried 1 of the 22 known tet genes examined. The distribution was as follows. The tet(A) gene was found in six isolates. The tet(B) gene was found in two isolates, including the first description in the genus Brevundimonas. Two isolates carried the tet(34) and tet(B) genes, including the first description of the tet(34) gene in Pseudomonas and Serratia and the first description of the tet(B) gene in Pseudomonas. The tet(H) gene was found in two isolates, which includes the first description in the genera Moraxella and Acinetobacter. One isolate carried tet(E), and one isolate carried tet(35), the first description of the gene in the genus Stenotrophomonas. Finally, one isolate carried tet(L), found for the first time in the genus Morganella. By DNA sequence analysis, the two tet(H) genes were indistinguishable from the previously sequenced tet(H) gene from Tn5706 found in Pasteurella multocida. The Acinetobacter radioresistens isolate also harbored the Tn5706-associated 1,063-bp IS element IS1597, while the Moraxella isolate carried a 1,026-bp IS-like element whose 293-amino-acid transposase protein exhibited 69% identity and 84% similarity to the transposase protein of IS1597, suggesting the presence of a novel IS element. The distribution of tet genes from the Chilean freshwater ponds was different than those that have previously been described from other geographical locations, with 40% of the isolates carrying unidentified tetracycline resistance genes.

ABSTRACT: In this work, we describe an unusual case of fibrinous pleuropneumonia caused by Pasteurella multocida associated with generalized lymphadenomegaly in a bovine. The animal had a one-month history of generalized superficial lymphadenomegaly that progressed to anorexia and submandibular oedema, resulting in spontaneous death. At necropsy, the parenchyma of the lymph nodes and multiple organs was obliterated by a dense proliferation of round neoplastic cells (lymphoma). Additionally, the neoplasm presented multifocal areas of haemorrhage and necrosis, characteristic of lymphoma. The parietal and visceral pleura and parietal pericardium were enlarged and covered diffusely with large amounts of a yellowish fibrillary material. The lungs were mildly enlarged, non-collapsed, and firm and exhibited interlobular septae that were thickened with a gelatinous material. Histopathological examination showed that the parietal and visceral pleura were enlarged due to a diffuse and severe inflammatory infiltrate composed of degenerate neutrophils associated with severe fibrin deposition, characteristic of fibrinous pleuropneumonia. Pleura and parietal pericardium fragments were cultivated in aerobic and microaerobic microbiological conditions. Round greyish colonies of gram-negative coccobacilli that were shiny and non-haemolytic were observed in sheep blood agar. The biochemical profile was indicative of Pasteurella spp. Molecular identification was performed by partial 16S rRNA amplification following sequencing. Pasteurella multocida was confirmed as the primary bacterium associated with the bovine fibrinous pleuropneumonia. We are able to infer that the lymphoma caused immunodepression, which increased the animal’s susceptibility to atypical infectious microorganisms such as pathogenic P. multocida.

A healthy male farm employee developed an unusual infection caused byPasteurella multocida. Atypical features included the chronic nature of the infection, the development of osteomyelitis of the tibia without direct animal inoculation, and lack of fever and leukocytosis. Radiographic appearance ofP multocidaosteomyelitis may be the result of osteoclast activation and can be confused with musculoskeletal tumour.P multocidainfection requires a high degree of suspicion, and should be considered in cases of farm- or animal-related injuries even if there is no history of direct animal contact.

In the history of botany, Adam Zalužanský (d. 1613), a Bohemian physician, apothecary, botanist and professor at the University of Prague, is a little-known personality. Linnaeus's first biographers, for example, only knew Zalužanský from hearsay and suspected he was a native of Poland. This ignorance still pervades botanical history. Zalužanský is mentioned only peripherally or not at all. As late as the nineteenth century, a researcher would be unaware that Zalužanský’s main work Methodi herbariae libri tres actually existed in two editions from two different publishers (1592, Prague; 1604, Frankfurt). This paper introduces the life and work of Zalužanský. Special attention is paid to the chapter “De sexu plantarum” of Zalužanský’s Methodus, in which, more than one hundred years before the well-known De sexu plantarum epistola of R. J. Camerarius, the sexuality of plants is suggested. Additionally, for the first time, an English translation of Zalužanský’s chapter on plant sexuality is provided.

This article describes a crucial and fundamental stage in the transformation of Hebrew children's literature, during the late 1930s and 1940s, from a single channel of expression to a multi-layered polyphony of models and voices. It claims that for the first time in the history of Hebrew children's literature there took place a doctrinal confrontation between two groups of taste-makers. The article outlines the pedagogical and ideological designs of traditionalist Zionist educators, and suggests how these were challenged by a group of prominent writers of adult poetry, members of the Modernist movement. These writers, it is argued, advocated autonomous literary creation, and insisted on a high level of literary quality. Their intervention not only dramatically changed the repertoire of Hebrew children's literature, but also the rules of literary discourse. The article suggests that, through the Modernists’ polemical efforts, Hebrew children's literature was able to free itself from its position as an apparatus controlled by the political-educational system and to become a dynamic and multi-layered field.

The article discusses the results of the latest interdisciplinary research of Czermno stronghold and its immediate surroundings. The site is mentioned in chroniclers’ entries referring to the stronghold Cherven’ (Tale of Bygone Years, first mention under the year 981) and the so-called Cherven’ Towns. Given the scarcity of written records regarding the history of today’s Eastern Poland, Ukraine, and Belarus in the 10th and 11th centuries, recent archaeological research, supported by geoenvironmental analyses and absolute dating, brought a significant qualitative change. In 2014 and 2015, the remains of the oldest rampart of the stronghold were uncovered for the first time. A series of radiocarbon datings allows us to refer the erection of the stronghold to the second half/late 10th century. The results of several years’ interdisciplinary research (2012-2020) introduce qualitatively new data to the issue of the Cherven’ Towns, which both change current considerations and confirm the extraordinary research potential in the archeology of the discussed region.

Dmitrii Mendeleev (1834–1907) is a name we recognize, but perhaps only as the creator of the periodic table of elements. Generally, little else has been known about him. This book is an authoritative biography of Mendeleev that draws a multifaceted portrait of his life for the first time. As the book reveals, Mendeleev was not only a luminary in the history of science, he was also an astonishingly wide-ranging political and cultural figure. From his attack on Spiritualism to his failed voyage to the Arctic and his near-mythical hot-air balloon trip, this is the story of an extraordinary maverick. The ideals that shaped his work outside science also led Mendeleev to order the elements and, eventually, to engineer one of the most fascinating scientific developments of the nineteenth century. This book is a classic work that tells the story of one of the world's most important minds.

The nineteenth century introduced developments in science and medicine that made the eradication of pain conceivable for the first time. This new understanding of pain brought with it a complex set of moral and philosophical dilemmas. If pain serves no obvious purpose, how do we reconcile its existence with a well-ordered universe? Examining how writers of the day engaged with such questions, this book offers a compelling new literary and philosophical history of modern pain. The book provides close readings of novelists Charlotte Brontë and Thomas Hardy and political and natural philosophers John Stuart Mill, Harriet Martineau, and Charles Darwin, as well as a variety of medical, scientific, and popular writers of the Victorian age. The book explores how discussions of pain served as investigations into the status of persons and the nature and parameters of social life. No longer conceivable as divine trial or punishment, pain in the nineteenth century came to seem instead like a historical accident suggesting little or nothing about the individual who suffers. A landmark study of Victorian literature and the history of pain, the book shows how these writers came to see pain as a social as well as a personal problem. Rather than simply self-evident to the sufferer and unknowable to anyone else, pain was also understood to be produced between persons—and even, perhaps, by the fictions they read.
