According to the WHO, zoonoses are diseases and infections that are naturally transmitted between vertebrate animals and humans. A subgroup of these diseases have been termed Neglected Tropical Zoonoses (e.g. Hotez

The file-drawer problem is the tendency of journals to preferentially publish studies with statistically significant results.
The problem is an old one and has been documented in various fields, but to my best knowledge there has not been attention
to how the issue is developing in a quantitative way through time. In the abstracts of various major scholarly databases (Science
and Social Science Citation Index (1991–2008), CAB Abstracts and Medline (1970s–2008), the file drawer problem is gradually
getting worse, in spite of an increase in (1) the total number of publications and (2) the proportion of publications reporting
both the presence and the absence of significant differences. The trend is confirmed for particular natural science topics
such as biology, energy and environment but not for papers retrieved with the keywords biodiversity, chemistry, computer,
engineering, genetics, psychology and quantum (physics). A worsening file-drawer problem can be detected in various medical
fields (infection, immunology, malaria, obesity, oncology and pharmacology), but not for papers indexed with strings such
as AIDS/HIV, epidemiology, health and neurology. An increase in the selective publication of some results against some others
is worrying because it can lead to enhanced bias in meta-analysis and hence to a distorted picture of the evidence for or
against a certain hypothesis. Long-term monitoring of the file-drawer problem is needed to ensure a sustainable and reliable
production of (peer-reviewed) scientific knowledge.

The purpose of this paper is to present the preliminary results of a bibliometric analysis of AIDS documents as produced on
Sub-Saharan Africa. AIDSLINE 1980-2000 was used to conduct the literature search. In this paper, an analysis was made only
of the records retrieved under "Central Africa". Bibexcel (version 2001) and Microsoft Excel (2000) were used as software
tools to conduct the analysis of the records. Seven countries and 1052 records were identified. Main participating countries
were Democratic Republic of the Congo (527 documents), and Cameroon (271). Results indicated a high pattern of collaboration
through multiple authorship. Most documents were published in English (84.50%) and French (14.73%). Over 57% corresponded
to journal articles. The subject content of the documents was mainly focused on epidemiological, complications, and prevention
& control issues on ‘HIV Infections’ and ‘Acquired Immunodeficiency Syndrome’. Countries behind this productivity were Cameroon,
USA, Democratic Republic of the Congo, France, and Belgium. Comparison of results among Central African countries and among
other developing countries is made by the authors.

The purpose of this paper is to present the preliminary results of a research in progress regarding the subject content analysis
of AIDS literature, as produced in or about the Latin American and Caribbean (LAC) region. An AIDSLINE/OVID literature search
was conducted to obtain only the Medical Subject Headings (MeSH)-geographic-terms related to the LAC region. The period of
study was from 1982 to June, 1998.
Indicators regarding the distribution of records throughout the years of study, as well as the subject, check tags, and subject/subheadings
distribution patterns were analysed. This was done through the application of a modular bibliometric information system, as
well as the applications of Biblio-Link for Windows, Version 1.2 1994–1997, Research Information Systems; Pro-Cite for Windows,
Version 4.0.1 1995–1998, Research Information Systems; and Microsoft EXCEL 97, of 1985–1998, Microsoft Corporation.
A total of 4124 records were obtained and analysed. In descending order, Brazil, Mexico, Haiti, Argentina and Puerto Rico,
generated the highest number of citations. Highly ranked MeSH subject headings wereRisk Factors; Acquired Immunodeficiency Syndrome; Sex Behavior, Support, Non U.S. Govt.; HIV Infections; andDeveloping Countries.
Results demonstrate that major research concerns centred on the epidemiological aspects and transmission of AIDS; and more
recently, on the prevention and control of the disease. A swith of the studies from male to female, and from middle age to
adolescence was also observed. The authors provide further lines of research.
