Book Description
This book presents the variability of the effects of Covid-19 on the nervous system (NS), with the purpose to update content and images based on improved scientific evidence. Current available data show that involvement of the NS is frequent in patients with SARS-CoV-2 infection. The most common neurologic syndromes include cerebrovascular disorders, encephalopathies, inflammatory Central Nervous System (CNS) syndromes, peripheral neurologic disorders, psychiatric disorders. The pathophysiology of neurological manifestations is far from being understood. They can be coincidental, common complications of severe viral infection, or direct consequence of the viral infection either via indirect para-infective mechanisms or direct viral penetration of NS. Experimental animal models had previously demonstrated the neuroinvasive potential of SARS-CoV and the detection of viral particles in special structures such as the thalamus, nucleus ambiguous and nucleus of the solitary tract, suggesting that CNS invasion can contribute significantly to the severe outcome not only through direct damage to neurological structures, but also through a potential detrimental effect on cardiorespiratory responses. Up to now, the detection of SARS-CoV-2 RNA in the cerebrospinal fluid of COVID-19 patients has been reported occasionally and conclusive pathological demonstration of the virus in the CNS is lacking. In this scenario, the role of neuroimaging is fundamental. These considerations highlight the urgent need to better clarify the neurotropic potential of the SARS-CoV-2 virus, and to verify on human autoptic tissue the mechanisms demonstrated in the experimental animal model in order to develop potential strategies to prevent CNS invasion and to adapt treatment protocols based on neurological involvement. CT scan is useful to detect large hemorrhage and ischemic lesions, that have been reported in Covid-19 patients, but lacks identifying other possible neurological complications, such as microhemorrhage or encephalitis. MRI could overcome these limitations; in particular the use of specific sequences may reveal microvascular lesions that can occur during the disease course, according to the described pathogenesis. This book will be an invaluable tool for neuroradiologists, radiologists, neurologists, and all physicians involved in the pandemic.

Book Description
'It is a small treasure chest of information presented in a compact textbook format. The unique contribution of this volume is the authors' ability to seamlessly bridge our current understanding of the basic science and genetics of this group of disorders to the clinical aspects of each epilepsy ... In short, those who practice in the field of epilepsy will find this text an easily accessible mini encyclopedia of reviews of our current understanding of the mechanisms that underlie the various childhood epilepsies. Readers will appreciate the digestible length and level of detail of each chapter and enjoy grabbing this book off the shelf.'Journal of Paediatric Epilepsy This is a collection of chapters from renowned authors focused on the contemporary issues in developmental epilepsy, from both clinical and basic science perspectives. Developmental epilepsy (or epilepsy syndromes), while receiving much more attention than 20 years ago, is still not well understood. This lag in research is reflected in the challenges of treating developmental epilepsy. The book discusses these challenges in the clinic and brings them back to the laboratory bench (and in some cases back to the bedside). This book fills a gap in the literature on developing epilepsy by bridging current clinical knowledge with basic and translational research in the developing brain relevant for developmental epilepsy.The book is introduced by a chapter on brain development to provide a background for understanding when and how seizures and epilepsy can emerge. Recent clinical research indicates strong relationship between childhood epilepsy and developmental cognitive impairment. This connection can be studied in experimental animals and can uncover developmental mechanisms common to both conditions. Targeting those mechanisms might reveal disease-modifying treatments. Febrile seizures are very common in the pediatric population and their impact on further epilepsy development is explored. The link between immunity, inflammation and epileptogenesis in the developing brain is explored. Many developmental epilepsies arise from brain malformations or neuronal migration deficits; some juvenile epilepsies have a clear genetic basis while the etiology of others is less certain. Recently, the involvement of the mTOR pathway in certain childhood epilepsy syndromes was recognized, prompting the repurposing of drugs used in cancer treatment for therapy of these specific epilepsy syndromes. Steroid hormones have significant hormonal effects on neurotransmitter receptors and function, and therefore have an impact on childhood epilepsy; sex steroids may have long term organizational effects on brain structure and epilepsy development. Stress, even early in development, may affect the developing brain and lead to behavioral changes as well as increased susceptibility to seizures.

Book Description
A novel public health concept, the Fangcang Shelter Hospital was first proposed by Professor Wang Chen, an academician of Chinese Academy of Engineering, in Wuhan, China, in February 2020. While responding to the coronavirus disease 2019 (COVID-19) outbreak, medical staff faced the pressing situation of limited medical supplies, which led Professor Wang Chen to the suggestion of converting large-scale public venues such as exhibition centers and indoor stadiums into shelter hospitals to receive large number of patients, as this involved minimum time and monetary costs. The five essential functions of Fangcang Shelter Hospitals (isolation, triage, provision of basic medical care, frequent monitoring and rapid referral, and essential living and social engagement) enable shelter hospitals to receive patients with mild to moderate symptoms of COVID-19, and have the greatest impact on isolating the source of infection and expanding the area's health-care capacity.Two of the first three Fangcang Shelter Hospitals set up in Wuhan were redeveloped by Zall Group Property from existing buildings, while Zall Foundation was responsible for the provision of essential medical supplies and logistical support to facilitate the running of these shelter hospitals. In total, the two shelter hospitals have been instrumental in diagnosing, treating and curing 3663 patients. Under the medical expertise and guidance of Professor Wang Chen, as well as inputs from Zall Foundation's crews who contributed to the design, renovation and operation of these shelter hospitals, this manual encompasses knowledge and experience distilled from the running of these Fangcang Shelter Hospitals. Covering five important aspects, namely the proposal, design, renovation, operation, and logistical support for shelter hospitals, this booklet aims to be a useful reference for other epidemic prevention and control efforts in regions around the world. The manual has been translated into more than 20 languages.
