Toxocara is a parasitic helminth worm which continues to stimulate both public concern and scientific interest. Toxocara canis and T.cati, the most studied species, are gastrointestinal parasites of dogs and cats and their eggs can contaminate the environment, thus exposing humans and other mammals and birds to infection. Many questions remain unanswered about the host-parasite relationship, its epidemiology and public health significance. Veterinarians and clinicians are interested in its importance as a zoonosis. The parasite's capacity to cause ocular disease is of concern to ophthalmologists, while its propensity to stimulate allergic manifestations is of interest to allergologists, dermatologists and respiratory medicine specialists. Furthermore Toxocara provides a unique model system to explore questions in parasite biology.This book provides a comprehensive review of Toxocara and the disease it causes known as toxocariasis.

This Atlas provides cutting-edge information on uveitis, which represents a major achievement in clinical studies on uveitis. It includes more than three thousand imaging photos of uveitis patients, showing the disease’s complete profile and the spectrum of variations commonly encountered. Numerous therapeutic regimens are also presented, each of which is designed for a specific form of uveitis. The Atlas also incorporates the latest advances in uveitis studies, making it a unique and valuable resource for a broad readership, including ophthalmologists, postgraduate students, medical students and doctors in ophthalmology.

Cysticercosis, an infection caused by the cystic larvae of the pork tapeworm Taenia solium, is one of the most frequent parasitic infections of the human nervous system (neurocysticercosis). It is endemic in most of Latin America, the sub-Saharan Africa, and vast parts of Asia, including the Indian subcontinent. It has also been increasingly diagnosed in developed countries because of migration of people from endemic zones and exposure in travelers. The life cycle involves the development of the adult tapeworm in the human small intestine (after ingesting infected pork with cysts) and larval infection in pig tissues (after ingesting human stools containing the eggs of the tapeworm). Humans get infected by the fecal-oral route, most often from a direct contact with an asymptomatic Taenia carrier. Most common clinical presentations are seizures (particularly late-onset seizures), chronic headaches, and intracranial hypertension. However, cysticerci can locate anywhere in the human nervous system, thus potentially causing almost any neurological syndrome and making clinical diagnosis a difficult task. Neuroimaging is the main diagnostic tool, and specific serology confirms the diagnosis and helps to define the diagnosis when images are unclear. Factors such as location (extraparenchymal versus intraparenchymal), number, size and evolutive stage of the parasites determine the clinical manifestations, therapeutic approach, and prognosis. Management includes symptomatic drugs (analgesics, antiepileptic drugs, anti-inflammatory agents) and in many cases cysticidal drugs, either albendazole or praziquantel. In recent years, efforts have focused on transmission control and potential elimination in endemic regions.

This book contains 19 chapters focusing on Toxocara and the disease it causes known as toxocariasis. The chapters are divided into the following parts: molecular biology (3 chapters); Toxocara as a model system (2); animal models for toxocariasis (1); human disease (4); immunology of toxocariasis (2); epidemiology of toxocariasis (3); Toxocara in the veterinary context (3); economic impact of the disease (1). It will interest a wide range of general, veterinary and medical parasitologists as well as clinicians and those concerned with public health.

This well-structured and lavishly illustrated book is a comprehensive reference on intraocular inflammation that encompasses all anatomic forms, settings and etiologies. Individual sections are devoted to uveitis associated with systemic disorders, uveitis syndromes restricted to the eye, bacterial uveitis, viral uveitis, fungal uveitis, parasitic uveitis, uveitis caused by other microbes, traumatic uveitis, and masquerade syndromes. Chapters on the different forms of uveitis are in a homogeneous reader-friendly format, with identification of core messages, explanation of etiology and pathogenesis, up-to-date information on diagnostics and differential diagnosis and guidance on the most appropriate forms of treatment and prognosis. Helpful flow charts are included to assist in identification of potential underlying disorders and the reader will also have online access to one hundred informative case reports demonstrating the different courses of intraocular inflammation. The authors are world experts keen to share their vast experience with the reader. Intraocular Inflammation will be a valuable resource for all physicians who deal with patients with inflammatory eye disease.

Intraocular inflammation is particularly difficult to diagnose and treat, often resembling a complex puzzle of patient history, symptoms, imaging, and laboratory test results. Clinical Cases in Uveitis: Differential Diagnosis and Management is a unique, case-based resource designed to help you navigate the range of challenging manifestations and presentations that often mimic other diseases. More than 90 real-world uveitis cases are presented in a highly templated, easy-to-follow format, along with step-by-step guidance on the right patient questions, assessment, differential diagnosis, testing, management, and follow-up care. Provides a variety of patient presentations and scenarios and unique clinical situations that mirror day-to-day practice. Covers current diagnostic imaging modalities, including optical coherence tomography (OCT), optical coherence tomography angiography, fluorescein angiography (FA), and indocyanine green angiography (ICG). Features diagnostic and management algorithms that assist in differential diagnosis and decision making for even the most complex cases, including those in which the patient does not improve as expected, prompting a reassessment of diagnosis and management. Contains approximately 250 high-quality images, including color anterior segment photographs, color fundus photographs, OCT images, and angiograms. Discusses distinguishing infectious from non-infectious inflammation; when and how to start systemic immunosuppressive therapy; diagnostic criteria and management of “white dot syndromes ; pediatric uveitis; masquerade syndromes, including inherited retinal degenerations, malignancies, and paraneoplastic syndromes; and much more. Includes the authors’ specific thought processes and approach in particularly challenging cases. An excellent resource and study tool for ophthalmology residents and fellows, those studying for oral boards, general ophthalmologists, retina specialists, and more.
