Introduction
An indexing System provides only bibliographic information
that is indexed by topicAn abstracting
Service provides a brief description (abstract) of information contained in a specific citation
Secondary Literature 4
Introduction
Indexing and abstracting provide access to primary literature each covers – different biomedical journals,– meeting abstracts– newsletters – textbooks– other publications
therefore, use of more than one of these resources
often allows for more thorough information retrieval.
Secondary Literature 5
Availability
CD-ROM format (IDIS) Internet, such as Grateful Med or PubMed from the National Library of Medicine (<<http://www.nlm.nih.gov>>).
Secondary Literature 6
achieve rapid access to literature information (any accumulated data..)literature source are organized by subject headings(… search the system and recover data pertaining directly to the information needed)key indexing terms … consists of the following:– Primary indexing terms– Descriptive modifying terms– Access numbers
Indexing:
Secondary Literature 7
Constitute the appropriate key term under which the information is filled in the relevant literature sources.
It provides the searcher with an efficient method to identify and locate information or answers pertaining directly to the type of information needed.
Primary indexing terms
Secondary Literature 8
……..primary indexing term being as specific as possible and use the generic name of the drug where feasible.
Depending on the origin in addition to the generic name of drug or other key indexing terms may be used, the most common terms frequently used are listed as follows:
Primary indexing terms(cont.)
Secondary Literature 9
Trade name, this used only, if the drug under which the information required to be filled is a combination product ( e.g. MAALOX
The name of therapeutic or chemical class of drugs, if the information concerning a class of drugs rather than a single drug (e.g. Corticosteroids and Anti-inflammatory agents).
The name of specific disease when the question or the information pertains to a drug related aspects of disease states (e.g. Leukemia and Hypertension).
Primary indexing terms
Secondary Literature 10
In case that the information is about investigational drugs, letters and/or numbers can be used as primary index, e.g. A-56258.
Information related to specific subject rather than a specific drug, a name of noun can be used as a primary index. For example information about insulin pump is indexed under pump, insulin.
Primary indexing terms(cont.)
Secondary Literature 11
In certain situations information are difficult or not suitable for indexing under one of the previously mentioned primary indexing terms.
In order to provide uniformity in assigning primary indexing terms a more specific term can be used in indexing of these information as the following examples:
Primary indexing terms
Secondary Literature 12
– Availability of particular drug.– General information concerning drug abuse.– Drug packaging information, this is usually
indexed under drug container and closures name in accordance to terms used by Index Medicos.
– Legal matters dealing with drugs (e.g. regulation).
Primary indexing terms
Secondary Literature 13
Is a term used to modify or describe the primary indexing term. It should be specific and concise as possible to be accessible one. It is usually consists of one or two word phrases describing briefly the nature of the requested information. It is often includes terms such as:– Dose:Mefinamic acid- dosage, normal adults --
Descriptive modifying terms– Pharmacokinetics:Bacoarnpicillin - Drug concentration level, therapeutics,– Interaction:Becampicillin - Erythromycin, interaction --- Erythromycin -
Bacompicillin, interaction
Descriptive modifying term
Secondary Literature 14
Used to locate the information or request pertaining to the modifying term.Example:– A question was received in a drug information center
regarding the adult dose of Ibuprofen to be used by a patient with renal failure.
– Such question will be indexed as follows:
– Ibuprofen- Renal Failure, dosage (Adult) ….464 Access number
– Primary indexing term Hyphen Descriptive
modifying indexing term
Access number
Secondary Literature 15
Abstracts are summaries of the content of information appearing in published articles, constructed to be a major device for information storage, or retrieval system.main types of abstracts:
1. Indicative abstracts (Non-evaluative or Descriptive abstracts)
These are brief outlines of the subjective materials in an articles in which details are omitted.(50-100 wards)
2. Informative Abstracts (evaluative abstracts) These should contain all key concepts and
important information mentioned in the article. (about 250 wards)
Abstracting
Secondary Literature 16
To indicate to readers quickly whether the full article would be useful to readTo be extracted (or abstracted) from the article for separate publication (e.g., by Biological Abstracts or Chemical Abstracts)To provide terminology to assist in literature searches by individuals or by literature retrieval specialists for indexes and computer banks.(Key Words)
Purposes Of Abstract
Secondary Literature 17
Informative self-explanatory without referring to the main text. generally restricted in length (not exceeds 250 words)complete abstract should state clearly the objective of the study and summarizing the procedure results and author’s conclusion.
Materials to be abstracts usually falls into one of the following classes:

REPORT
Secondary Literature 25
Single dose intravenous (JV) ciprofloxacin (I) and cefotaxime (II) are evaluated in a double blind study in male patients, 37 receiving, 1,300 mg, and 39 receiving II, 1.0 g, for preoperative prophylaxis in transurethral surgery. There were no symptomatic urinary tract infections or other infections after prostate and bladder surgery and no serious post surgery complications in any of the patients. Serum and prostatic tissue levels, as well as the tissue/serum ratios are included for 13 I patients. The most common side effect was postoperative nausea in 15 patients, 111 and 4 II patients. It is concluded that both drugs are effective and safe in reducing tree frequency of bacteriuria following transurethral surgery; there is no significant different between the 2 groups.

“The risk of drowning was less among children wearing life

“If the association estimated in our study is causal, our results provide evidence that about half of child drowning’ s can be prevented if children
wear life vests.”
