Emergencies of the Orbit and Adnexa
Author: Bipasha Mukherjee
Publisher: Springer
ISBN: 8132218078
Category : Medical
Languages : en
Pages : 484
Book Description
This handbook on orbital, lacrimal and eyelid emergencies deals with such situations in a practical manner guiding the ophthalmologists in accurate handling and making them more proficient and confident in managing vision and life-threatening emergencies. With 51 chapters and more than 350 images, this book covers all the eye emergencies that generalist and specialist ophthalmologists can expect to come across in their day to day practices. It can be argued that the orbit can no more be called ‘Pandora’s Box’ because of the unpredictable nature of its contents. This perception has changed over the years due to the advent of improved diagnostic, in particular, imaging techniques. However, since medical residency provides very little exposure to orbital and adnexal disorders, most clinicians are inexperienced and unsure about their management. Facing an emergency situation where improper management can rapidly worsen the condition leading to blindness or even death of the patient is every ophthalmologist’s nightmare. The emergent nature of these conditions does not always provide for a leeway to refer these patients to an orbit and oculoplasty specialist, who are few and far between. By the time the patient reaches his destination, his vision maybe irrevocably lost. The legal implications of such mismanagement can be significant too. This book is a quick and essential resource to manage and refer eye emergencies with confidence.

Psychiatric Care of the Medical Patient
Author: Barry S. Fogel
Publisher: Oxford University Press
ISBN: 0190226293
Category : Medical
Languages : en
Pages : 1813
Book Description
The third edition of Psychiatric Care of the Medical Patient brings a classic reference text into the twenty-first century. It combines critical scholarship with the voice of expert clinicians who work at the interface of psychiatry with medical specialties. It is meant to be read for pleasure as well as consulted as a reference. The editors have worked with the authors to bring a consistent perspective to the book - one that sees the medical psychiatrist as an agent for bringing a more comprehensive perspective to medical care. Even seasoned and knowledgeable practitioners will find much that is new to them in this book. The volume covers topics in depth that other books in the field may not cover at all, such as the use of herbal and nutritional therapies for medical-psychiatric symptoms and syndromes, and the choice of questionnaires to supplement history-taking. It looks at old topics in a new way: The chapter on the physical examination applies psychometric considerations to the Babinski sign, describes the method and application of quantitative bedside olfactory testing, and discusses smartphone apps to improve the sensitivity of the examination. Psychiatric Care of the Medical Patient, 3rd Edition provides concepts and information to facilitate the dialogue between psychiatrists and general medical specialists - minimizing psychiatric jargon and speaking in the common language of caring and curious physicians.

Scleritis
Author: Carlos Pavesio
Publisher: Springer
ISBN: 3319499157
Category : Medical
Languages : en
Pages : 125
Book Description
This book offers a concise but comprehensive overview of scleritis, with up-to-date information on all aspects, including diagnosis and treatment. Fundamental features of the pathogenesis of scleral inflammation are first discussed as a basis for understanding the therapeutic strategies. Detailed descriptions are then provided of clinical manifestations, the complications that can arise during the course of the disease process, and the best way to manage them. An individual chapter is devoted to infectious scleritis and its management, this being an uncommon but serious condition that may result not only in loss of vision but also in loss of the globe itself. The diagnostic approach to and various management options for scleritis are then discussed extensively, with coverage of local and systemic therapy and new strategies, including biologics. Apart from the potential impact on vision, inflammation of the sclera carries a risk of association with systemic diseases, some of which can prove fatal if not promptly recognized and managed. This book is designed to allow ophthalmologists to easily identify the condition and the signs indicative of a more severe problem. It will thereby assist in safe and effective management, and help in preserving vision and life.
