Recovery of mimic function after facial nerve transection is poor: the successful regrowth of axotomized motoneurons to their targets is compromised by (i) poor axonal navigation and excessive collateral branching, (ii) abnormal exchange of nerve impulses between adjacent regrowing axons and (iii) insufficient synaptic input to facial motoneurons. As a result, axotomized motoneurons get hyperexcitable and unable to discharge. Since improvement of growth cone navigation and reduction of the ephaptic cross-talk between axons turn out be very difficult, the authorsa concentrated on the third detrimental component and proposed that an intensification of the trigeminal input to axotomized electro...
This unique book presents a series of concisely written technical notes on common procedures in surgical oncology. Each operation is illustrated with pictures framing precise technical points. The book is accompanied by a CD-ROM that includes video clips of the procedures. Written by top European experts, this volume will provide an invaluable resource for young surgical oncologists to familiarize with technical details, develop a critical approach and expand their surgical skills. It will also be a useful source of reference for medical oncologists, radiologists, radiotherapists and nurses, as well as final-year medical students. Sample Chapter(s). Foreword (41 KB). Chapter 1: Axillary Lymp...

In the past several decades, the medical community has witnessed professionals, instead of generalizing their knowledge, specialize in a specific area of practice. Head and neck surgery have thus become a major specialty within the surgical domain, and the management of specific gland disorders encompasses a broad array of both benign and malignant diseases. Diagnostic Techniques and Therapeutic Strategies for Parotid Gland Disorders is a collection of innovative research on the clinical and diagnostic techniques as well as several therapeutic strategies of parotid gland disorders. Serving as a quick reference and practice manual, the book addresses a wide range of topics including embryological development and anomalies, histology and surgical anatomy, physiology, parotid gland evaluation, xerostomia, traumatic injuries and fistulae, calculi, sialosis, sialadenitis, cysts and tumors of the parotid gland, and the various techniques and potential complications of parotidectomy including Frey's syndrome, in addition to extra-temporal facial nerve reconstruction procedures. It is ideally designed for medical professionals, surgeons, researchers, academicians, and medical students.
Volume therapy or infusion therapy is used worldwide for the treatment of hypovolemia caused by surgical blood and plasma losses, trauma, burns, or infections. Interestingly, significant differences exist between countries regarding the use of plasma substitutes. In the United States, crystalloids and albumin are more popular, whereas in Europe artificial colloids such as hydroxyethyl starch are preferred. From an international perspective, it is notable that volume therapy using hydroxyethyl starch is an established therapy for the treatment of cerebral, retinal, otogenic, and peripheral circulation disorders in Germany. In other countries, crys talloids are mostly used to treat dehydration...
A collection of selected works presented by Spanish research teams at the establishment and consolidation of the Spanish Glial Network in February 1997. Includes: morphology and ontogeny, molecular and biochemical properties, pathology, and involvement in damage and regeneration. For researchers, clinicians, students, and teachers.
From recent developments in the rapidly growing area of neuroscience it has become increasingly clear that a simplistic description of brain function as a broad collection of simple input-output relations is quite inadequate. Introspection already tells us that our motor behavior is guided by a complex interplay between many inputs from the outside world and from our internal "milieu," internal models of ourselves and the outside world, memory content, directed attention, volition, and so forth. Also, our motor activity normally involves more than a circumscribed group of muscles, even if we intend to move only one effector organ. For example, a reaching movement or a reorientation of a sens...
