The purpose of this paper is to examine patterns of drug use among a cohort of drug treatment-seeking drug-using gay men and other men who have sex with men (MSM), and whether these activities differ between, or predict, HIV status.

Cross-sectional study was conducted in a specialist club drug clinic in London covering 407 consecutive attendees who identified as MSM. Substance use, including injecting drug use (IDU), associated sexual activity and self-reported HIV status were measured by clinical interview and National Drug Treatment Monitoring System data tool.

Over a 45-month period, 407 MSM attended the clinic. In total, 62.1 per cent were HIV positive, 48.9 per cent had injected drugs, 14.9 per cent reported needle sharing and 73.3 per cent used drugs to facilitate sex. The most commonly reported problem drugs were GHB/GBL (54.3 per cent) methamphetamine (47.7 per cent) and mephedrone (37.8 per cent). HIV status was associated with methamphetamine, mephedrone, IDU, sharing equipment, using drugs to facilitate sex, older age and older age of drug initiation, as well as Hepatitis C virology (HCV) status. Use of methamphetamine, HCV infection, older age and IDU predicted HIV positive status in a logistic regression model.

The findings describe a constellation of risk factors including high levels of IDU, sharing of equipment and high-risk sexual activity in a population with high rates of HIV positive serology. They also provide further evidence for a link between HIV infection and use of methamphetamine.

The authors suggest a need for greater awareness of HIV-related risk activities and promotion of HIV prevention strategies for MSM by both sexual health and drug treatment services.

This paper is amongst the very first studies of its nature.

Human diet consists of an enormous variety of both plants and animal proteins, many of which are potentially immunogenic. Industrial processing of foods and digestion in the gastrointestinal tract causes changes and breakdown of proteins into peptides, which are also potential immunogens. Foods commonly known to cause allergic reactions are fish, milk, eggs, fruits, vegetables, nuts, legumes and meat. Once sensitised to a particular antigen, subsequent exposure may result in a marked and immediate reaction characterised by vomiting, diarrhoea, abdominal cramps, itching and swelling of the mouth and skin, dizziness and occasionally systemic anaphylaxis. Allergic reactions involve complex processes and interactions between the allergen and immunological components in the digestive tract such as antigen absorption, processing and presentation, T cell and B cell activation, development of oral tolerance or allergic sensitivity, antigen‐specific IgE antibody synthesis. Allergen binding to allergen‐specific mast cell membrane‐bound IgE antibodies triggers mast cell degranulation. This results in the release of histamine and other chemotactic mediators responsible for clinical symptoms.

JOHANN FROBEN, the famous printer of Basle, was born at Hammelburg, in Franconia, about the year 1460. The exact year of his birth is not definitely known, but 1460 is probably not far wrong, as we find him established at Basle as a printer in 1491. He was educated at Basle University, where he distinguished himself as a scholar, particularly in the Latin, Greek, and Hebrew languages. After finishing his studies at Basle, he turned his attention to the then new art of printing, and he showed such aptitude that Johann Amerbach, another well‐known printer of Basle, who had set up a press in that city in 1481, induced him to devote his energies to the art, and appointed him to a position in his own printing establishment. Froben thus had the advantage of learning the art of printing under one of the best known printers of the period. In 1491, Froben set up a press of his own in Basle, having become a naturalized citizen of that city the previous year. He had been used in Amerbach's establishment to print with gothic types, and it was, therefore, but natural that his first production should also be printed in that type. This was an octavo Latin Bible, with two columns to a page, printed in a very small gothic type. He afterwards introduced the type invented by Aldus, that known as italic, the first book to be printed with this type being the Adagia of Erasmus, issued in 1513, of which mention is made later. Froben was also instrumental in making the roman type more popular in Germany, as although roman type had been used by German printers for about 20 years, having been introduced by Mentelin at Strassburg, about the year 1470, it was not so much in favour as the gothic type.

A number of distinguished guests of the President were present, including Sir Owen Wansbrough‐Jones, K.B.E., C.B., The Chief Scientist, Ministry of Supply, Vice‐Admiral N. E. Dalton, C.B., O.B.E., Engineer‐in‐Chief to the Fleet, The Rt. Hon. The Viscount Simon, C.M.G., President of the Chamber of Shipping, Air Chief Marshal Sir Walter Dawson, K.B.C., C.B.E., D.S.O., Air Member for Supply and Organisation, The Air Ministry, and many Presidents of scientific institutions, Past‐Presidents of the I.Pet., Directors of leading oil companies, etc.

This leadership education evaluation study explored the leadership development outcomes of potential county extension directors and the ways to improve the program. The leadership education program aimed to improve participants’ leadership abilities in understanding self, building relationships and managing resources. The analysis of quantitative and qualitative data confirmed that the leadership training institute was effective in building participants’ leadership skills and improving leadership behavior. The incorporation of participants’ learning needs into the program, use of hands-on experiential learning activities and problem solving activities combined with small group discussions were the contributing factors for the success of this leadership education program. The participants suggested the use of more hands-on and problem solving activities, team building exercises and condensing the time gap between the pre and post sessions as strategies for further improvement of this program.

1. Jones, J. Owen and Elizabeth A. Jones. Index of Human Ecology. London, Europa Publications Limited, 1974. 169p. $16.00. Here, at least as far as this reviewer is aware, is a unique approach in print to one of the broad interdisciplinary areas that is bringing so many interesting, and now and then frustrating, questions to our reference desks. Human ecology is tentatively defined by the authors as “the study of the interrelation of man and his environment,” but since humans have created each element in the record of human knowledge, there must be little if anything in that record that is not included within the scope of this definition. Yet most people would agree to the exclusion of some subjects‐astronomy, for example. The authors do not provide a concise, precise definition of their subject; hence each of us is left with his own somewhat vague notion of what the subject is, and each of us will probably disagree to some extent with what has been included, and what has not. Instead of defining their subject, the authors polled the members of the Commonwealth Human Ecology Council, and produced a list of subjects that overlap with human ecology. Their objective, which is highly commendable from the point of view of the reference librarian and his patrons, is to produce a subject index to the abstracting journals which cover these subjects.

Here, we examine the challenges to democratization in Bahrain, with a particular focus on how the recent 2011 Uprising has resulted in a deepening of authoritarianism. It is argued that the recent unrest has brought into sharp relief the absence of “quality” democracy in Bahrain, and that any form of democratic transition is dependent on the will of a conservative Al Khalifa-Saudi nexus. While the pro-democracy movement may have prompted minor concessions on the part of the government, the extent of the popular mobilization triggered the Al Khalifa regime’s authoritarian reflex, and they have reacted to throttle the Uprising by putting in place legislative, ideological, and political barriers to reform, which points not only to a current de-democratization, but also a lack of future democratization. In addition to arguing for the post-2011 undoing of democracy in Bahrain, this paper also points to two major barriers to future democratization; (1) a conservative, post-Independence Al Khalifa-Saudi coalition assisted by large military resources (2) protracted communal tension brought about by the government’s instrumentalization of sectarianism.
