Its intent was not to be a heavy book that could only be stored on a bookshelf, but a pocket-sized reference that could be carried, easily navigated, and available whenever a conceptual gap compromised the interventionalist’s ability to perform. The editor recog- nized this need in her own training and practice, and now that she teaches, has taken note of her fellows’ repeated frustration at not having reference book at hand with the answers to questions that arise at the bedside. The fact that Dr Gupta has managed to attract authors who are leaders in the field, including fellowship directors from programs throughout the US, confirms that indeed a need exists for such a book. The book is logically laid out, and each section covers the necessary material in a formulaic way: anatomy, indications, preparation, techniques, complications, clinical notes, and clinical pearls. The focus of the book is on technical aspects, and the book is adequately illustrated with fluoroscopic images and diagrams. The glossary, index, reading lists, and alphabetical contents make it easy to locate unfamiliar material, including where to look for information beyond this small book. Though this book is intended for new trainees in interventional pain management, it should also be noted that even the most seasoned practitioner will sometimes be required to perform an unfamiliar intervention, or will encounter an unusual clinical situation, in which case a ready reference book is invaluable. Thus, this book could well have utility not just for trainees, but for anyone practicing interventional pain management. Jane C . Ballantyne This page intentionally left blank xi Preface The care of pain patients requires a unique knowledge base and skill set that differs widely from that required for general patient management. The physiology of pain medicine is rapidly changing, with con- tinued advances made on interventions available to treat pain. The aim of this work is to provide, in one source, authoritative information from leaders in pain medicine to guide providers at the point of care for interventional pain therapies. It is intended to provide a rapid and accurate source of information relevant to the impact of the interventional management of pain patients. This handbook is an indispensi- ble resource for a variety of different pain practitioners who provide care to pain patients. This book provides point-of-care guide utilizing contributions of nationally and internationally recognized authors from institutions with advanced pain care practices and centers of excellence. I wish to acknowledge and thank the many outstanding faculty and fellows who contributed to the endeavor. I also want to sincerely thank Andrea Seils and Staci Hou from Oxford University Press for their dedication to this book and for making my vision for this work come to fruition.

  • Analysis of Rehabilitation Procedure Following Arthroplasty of the Knee with the Use of Complete Endoprosthesis

Material/Methods: We studied 33 patients following an initial total arthroplasty of the knee involving endoprosthesis. The patients were divided into two groups according to age. The range of movement within the knee joints was measured for all patients, along with muscle strength and the subjective sensation of pain on a VAS, and the time required to complete the ‘up and go’ test was measured. The gait model and movement ability were evaluated. The testing was conducted at baseline and after com- pletion of the rehabilitation exercise cycle. Results: No significant differences were noted between the groups in the tests of the range of movement in the operated joint or muscle strength acting on the knee joint.

  • Asphyxia Neonatorum
    CLINICAL REVIEW Asphyxia Neonatorum Raul C. Banagale, MD, and Steven M. Donn, MD Ann Arbor, Michigan Various biochemical and structural changes affecting the newborn’s well­ being develop as a result of perinatal asphyxia. Central nervous system ab­ normalities are frequent complications with high mortality and morbidity. Cardiac compromise may lead to dysrhythmias and cardiogenic shock. Coagulopathy in the form of disseminated intravascular coagulation or mas­ sive pulmonary hemorrhage are potentially lethal complications. Necrotizing enterocolitis, acute renal failure, and endocrine problems affecting fluid elec­ trolyte balance are likely to occur. Even the adrenal glands and pancreas are vulnerable to perinatal oxygen deprivation. The best form of management appears to be anticipation, early identification, and prevention of potential obstetrical-neonatal problems. Every effort should be made to carry out ef­ fective resuscitation measures on the depressed infant at the time of delivery. erinatal asphyxia produces a wide diversity of in­ molecules brought into the alveoli inadequately com­ Pjury in the newborn.

  • Knee Pain in Children: Part I: Evaluation
    Knee Pain in Children: Part I: Evaluation Michael Wolf, MD* *Pediatrics and Orthopedic Surgery, St Christopher’s Hospital for Children, Philadelphia, PA. Practice Gap Clinicians who evaluate knee pain must understand how the history and physical examination findings direct the diagnostic process and subsequent management. Objectives After reading this article, the reader should be able to: 1. Obtain an appropriate history and perform a thorough physical examination of a patient presenting with knee pain. 2. Employ an algorithm based on history and physical findings to direct further evaluation and management. HISTORY Obtaining a thorough patient history is crucial in identifying the cause of knee pain in a child (Table). For example, a history of significant swelling without trauma suggests bacterial infection, inflammatory conditions, or less likely, intra- articular derangement. A history of swelling after trauma is concerning for potential intra-articular derangement. A report of warmth or erythema merits consideration of bacterial in- fection or inflammatory conditions, and mechanical symptoms (eg, lock- ing, catching, instability) should prompt consideration of intra-articular derangement. Nighttime pain and systemic symptoms (eg, fever, sweats, night sweats, anorexia, malaise, fatigue, weight loss) are associated with bacterial infections, inflammatory conditions, benign and malignant musculoskeletal tumors, and other systemic malignancies. A history of rash or known systemic inflammatory conditions, such as systemic lupus erythematosus or inflammatory bowel disease, should raise suspicion for inflammatory arthritis. Ascertaining the location of the pain also can aid in determining the cause of knee pain. Anterior pain suggests patellofemoral syndrome or instability, quad- riceps or patellar tendinopathy, prepatellar bursitis, or apophysitis (patellar or tibial tubercle).
