The riddle of febrile seizures is that despite their high risk of recurrence (35% to 50%), the natural history of the disorder is benign for the vast majority of children.1 If daily phenobarbital administration for several years is to be recommended after the first febrile seizure, it must be shown to be exceedingly effective and safe. The commendable study of Woff et al. is the second2 prospective randomized trial with concurrent controls of the efficacy of phenobarbital to prevent recurrent febrile seizures.

Frozen shoulder, a common and debilitating shoulder complaint, has been the subject of uncertainty within the scientific literature and clinical practice. We performed an electronic PubMed search on all (1559) articles mentioning ‘frozen shoulder’ or ‘adhesive capsulitis’ to understand and qualify the range of naming, classification and natural history of the disease. We identified and reviewed six key thought leadership papers published in the past 10 years and all (24) systematic reviews published on frozen shoulder or adhesive capsulitis in the past five years. This revealed that, while key thought leaders such as the ISAKOS Upper Extremity Council are unequivocal that ‘adhesive capsulitis’ is an inappropriate term, the long-term and short-term trends showed the literature (63% of systematic reviews assessed) preferred ‘adhesive capsulitis’. The literature was divided as to whether or not to classify the complaint as primary only (9 of 24) or primary and secondary (9 of 24); six did not touch on classification. Furthermore, despite a systematic review in 2016 showing no evidence to support a three-phase self-limiting progression of frozen shoulder, 11 of 12 (92%) systematic reviews that mentioned phasing described a three-phase progression. Eight (33%) described it as ‘self-limiting’, three (13%) described it as self-limiting in ‘nearly all’ or ‘most’ cases, and six (25%) stated that it was not self-limiting; seven (29%) did not touch on disease resolution. We call for a data and patient-oriented approach to the classification and description of the natural history of the disease, and recommend authors and clinicians (1) use the term ‘frozen shoulder’ over ‘adhesive capsulitis’, (2) use an updated definition of the disease which recognizes the often severe pain suffered, and (3) avoid the confusing and potentially harmful repetition of the natural history of the disease as a three-phase, self-limiting condition.

✓ Cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH) is a disease process for which the lack of effective treatments has plagued neurosurgeons for decades. Historically, successful treatment after SAH in the acute setting was often followed by a rapid, uncontrollable deterioration in the subacute interval. Little was known regarding the nature and progression of this condition until the mid-1800s, when the disease was first described by Gull. Insight into the origin and natural history of cerebral vasospasm came slowly over the next 100 years, until the 1950s. Over the past five decades our understanding of cerebral vasospasm has expanded exponentially. This newly discovered information has been used by neurosurgeons worldwide for successful treatment of complications associated with vasospasm. Nevertheless, although great strides have been made toward elucidating the causes of cerebral vasospasm, a lasting cure continues to elude experts and the disease continues to wreak havoc on patients after aneurysmal SAH.

Some writers about the history of philosophy in Canada have wondered why it should be studied. That is a worthy question, but it is not the one I want to discuss here. I am going to assume there are good reasons for doing so because I want to consider some general features of the subject of such studies and to determine what has to be done to establish certain descriptive claims about it. I will also point out some concerns I have about the proper explanation of certain interesting features of Canadian philosophic activity, and I will present a brief evaluation of one major study. I will do this with the aid of a contention that the study of the history of an intellectual discipline is a little like an evolutionary study of a biological species, but I will close by pointing out one reason for doing history which goes beyond description, and even explanation, of the past.

This volume is dedicated to the Anthropological and Ethnological section of the Natural History Museum. First the historical journey of the collections is traced from the antique nucleus of the Medici to the foundation of the National Museum of Anthropology and Ethnology, when Florence was the capitol of Italy, and the discipline of anthropology was born. The second part illustrates the multivariate collections from all over the globe. They are a precious record of the past and present biological and cultural diversity of our species opening wide horizons that rigorously connect science to the many faces of human culture, including art. The third section is dedicated to current research and opens new prospectives on the significance of ethnological and anthropological collections due to new technology and in light of a new appreciation of the museum as a living “zone of contact”.

A database is an organized repository of data. Prospective collection of patient information in a database (`databasing') has been attempted by a few consortia of MS investigators over the past 10 years. This approach promises to facilitate epidemiologic research in MS and investigation of the natural history of the disease and how it might be altered by long-term treatments such as interferon beta. Databasing has some advantages over clinical trials in assessing new therapies, primarily because the focus is on long-term effectiveness in an entire population rather than short-term statistical significance in a highly selected population. The limitations of databasing and strategies to overcome these limitations are addressed.

In the past decade, there has been a growing recognition that society’s emphasis on speed and efficiency came with some costs: a loss of the ability to appreciate activities and understand their meanings.  Recently, this meta-movement has made its way into the literature on literacy, causing the author to embark on an investigation into the veracity of the claims that slow reading might also mean better reading.  A natural history approach was adopted for the analysis to evaluate whether there was evolutionary justification for the movement, leading to the review of relevant work in the fields of ethology, psychology, cognitive neuroscience, anthropology, sociology, linguistics, and literacy. The findings reveal an evolutionary push toward both speed and understanding, two aims that eventually come to be at odds in expert readers. It is the conclusion of the author that, from an evolutionary perspective, there may be justification for the start of a slow reading movement, but that it must be paired with practices that develop the capacity to read fast.
