Background: Concussions are one of the most common head injuries acquired within the pediatric population. While sport-related concussions are well documented, concussions within other aspects of a child’s life are not as well researched. The purpose of this study is to examine the incidence of a large pediatric concussion population in a broad range of daily activities. Methods: Patients’ gender and nature of injury were extracted from 1408 medical records of patients who were diagnosed with a concussion at Saint Peter’s Sports Medicine Institute. Statistical analyses were conducted for activities and environmental settings using chi-squared tests. Results: Concussions were most prevalent in organized sports (53.3%), followed by injuries within the following settings: school (16.5%), recreational (6.7%), motor vehicle collisions (6.6%), home (5.5%), and other (11.3%). Specifically, soccer (12.9%), school physical education (PE) class (10.6%), and football (9.8%) subcategories recorded the most incidences of concussion. For the PE class cohort (n = 149), significantly more females were diagnosed with a concussion compared to males (p < 0.001). Conclusions: PE-related concussions had the second highest incidence rate after organized sports. A significant gender difference was observed in PE class. Awareness about concussions and methods to reduce the risk of concussion is suggested for PE classes.

Electron microscopy (EM), with the advent of computer control and image analysis techniques, is rapidly evolving from an interpretative science into a quantitative technique. Electron microscopy is potentially of value in two general aspects of environmental health: exposure and diagnosis.In diagnosis, electron microscopy is essentially an extension of optical microscopy. The goal is to characterize cellular changes induced by external agents. The external agent could be any foreign material, chemicals, or even stress. The use of electron microscopy as a diagnostic tool is well- developed, but computer-controlled electron microscopy (CCEM) has had only limited impact, mainly because it is fairly new and many institutions lack the resources to acquire the capability. In addition, major contributions to diagnosis will come from CCEM only when image analysis (IA) and processing algorithms are developed which allow the morphological and textural changes recognized by experienced medical practioners to be quantified. The application of IA techniques to compare cellular structure is still in a primitive state.

During his lifetime, Nikolai Rimsky-Korsakov (1844–1908) was a composer whose work had great influence not only in his native Russia but also internationally. While he remains well-known in Russia—where many of his fifteen operas and various orchestral pieces are still in the standard repertoire—very little of his work is performed in the West today beyond Scheherezade and arrangements of The Flight of the Bumblebee. In Western writings, he appears mainly in the context of the Mighty Handful, a group of five Russian composers to which he belonged at the outset of his career. This book finally gives the composer center stage and due attention. In this book, Rimsky-Korsakov's major operas, The Snow Maiden, Mozart and Salieri, and The Golden Cockerel, receive multifaceted exploration and are carefully contextualized within the wider Russian culture of the era. The discussion of these operas is accompanied and enriched by the composer's letters to Nadezhda Zabela-Vrubel, the distinguished soprano for whom he wrote several leading roles. Other chapters look at more general aspects of Rimsky-Korsakov's work and examine his far-reaching legacy as a professor of composition and orchestration, including his impact on his most famous pupil Igor Stravinsky.
