One chapter reviews current mass-spectrometric instrumen tation and techniques, and other chapters describe the use of mass-spectro metric methods for the analysis of diacylglycerylphospholipids; modifications to DNA molecules; the characterization of variant hemoglobins; and...

Basophils and mast cells are similar but unique secretory cells with a well-documented role in immediate-hypersensitivity reactions. The presence of these cells in various cell mediated hypersensitivity reactions, in tissues of multiple diseases, and as a component of the host reaction to injury and repair in numerous circumstances is well known. Release of stored and newly generated mediators of inflammation from basophils and mast cells contributes to the cascade of pathogenetic events in circumstances under which these release reactions occur. Despite insights acquired through studies of...

We are most pleased to present Volume 3 of Developmental-Behavioral Disorders: Selected Topics, designed to serve as a companion for standard reference textbooks that address cogent issues in developmental pedi- atrics. Periodic publications such as Selected Topics and theme-related articles, as well as continuing education programs, attempt to supple- ment in a timely fashion the rapidly changing knowledge base in devel- opmental-behavioral pediatrics. These media are important as forums for enhancing the quality of clinical practice, teaching skills, and re- search activities. The need is...

"Child development" has always been a traditional component of well child care and a particular area of interest for pediatricians, child neu rologists, and psychologists. However, it was not until the early 1960s that children with developmental disabilities (i. e., chronic handicapping disorders) became a major focus of public and professional attention. During this period, children with "special needs" were dramatically catapulted into the limelight and "exceptional" became the buzzword of the day. Public and professional awareness of these issues reached new peaks and recognition of the...

Many residency programs in primary care specialties do not provide the education in pediatric orthopedics necessary to effectively deal with the field's challenges. Here, the authors present a framework for the effective evaluation of childhood musculoskeletal problems in a practical and problem-based manner. The volume contains case studies and over 200 illustrations.
