**Objectives \[ppt slides 1-4\]**: Learn how to search MEDLINE using the
PubMed interface. This includes:

1\. Basic searching

2\. Advanced searching using the Limits Tab and some field searching

3\. How to obtain full-text journal articles using Loansome Doc
(document delivery)

4\. The Journals Database for locating journal titles

5\. The Single Citation Matcher form for quick citation matching

6\. My NCBI Saved Searches (*optional -- time permitting*)

Note: This course will not cover all of the features in PubMed. After
all, we only have 3 hours!  However, we will cover the parts of PubMed
that public librarians will use most.

I.  Introduction

    A.  What is PubMed? \[ppt slide 5\]

-   Produced by the NCBI (National Center for Biotechnology Information)
    & NLM (National Library of Medicine)

-   All you need is a web browser to access PubMed.

-   PubMed is includes:

    -   **MEDLINE** is a database of biomedical journal citations that
        are indexed with subject headings.

    -   PubMed **in process** citations are the new citations that have
        gone through the first round of indexing and a quality review to
        check for errors. These citations will eventually be indexed
        with subjects headings and then become MEDLINE citations.

    -   **OLDMEDLINE** citations date back from the early 1950s to 1965.
        These records do not have abstracts nor do they have subject
        heading assigned.

    -   **Publisher-Supplied** Citations are non-MEDLINE citations that
        are included in PubMed because they were supplied electronically
        by the publisher. These citations are out of scope for indexing
        in MEDLINE. For example, articles from the journal *Nature* on
        volcanoes may never be indexed in MEDLINE.

    A.  What is MEDLINE? \[ppt slides 6-9\]

-   MEDLINE is the world's largest biomedical database.

-   *What does this mean?* MEDLINE covers medicine, dentistry,
    veterinary science, nursing and other biological sciences. Coverage
    is international (Includes over 4,800 journals from 70 countries)
    although many articles have English language abstracts.

-   Goes back to the mid-1960s

-   Produced/Indexed at NLM, who then leases the product (at no charge)
    to vendors who design software needed to search the database, such
    as OVID, etc.

    A.  PubMed Screen Layout \[ppt slides 10-11\]

-   Enter the URL that is printed in the Handout:
    [www.pubmed.gov](http://www.pubmed.gov/). This class will show us
    about the tools that we will use most often.

-   First, take a look at PubMed's sidebar (the blue bar on the left
    side) and describe the following:

    -   **Overview** *(click to show)*: Describes the scope of PubMed

    -   **Help/FAQ** *(click to show)*: Describes specific PubMed
        functions.

    -   **Tutorial**: If you want additional practice or a refresher,
        there is a tutorial for you to try.

    -   **New/Noteworthy**: This will update the user on changes to
        PubMed.

    -   **Journals Database**: Allows you to search for journals with a
        few words from the title, use the full title, abbreviation, or
        ISSN. We will look at this database later on.

    -   **MeSH Database**: Use this database to find appropriate MeSH
        term for word or phrase.

        -   *Inquire if anyone knows what MeSH is. MeSH stands for
            "Medical Subject Heading". We will not be using this tool in
            today's class because this is quite extensive and entire
            classes have been devoted to using MeSH. Just be aware that
            this is the specific controlled vocabulary used in MEDLINE.*

    -   **Single Citation Matcher**: Lets you use a fill in the blank
        form with only partial bibliographic information.

    -   **Batch Citation Matcher,** **Clinical Queries** and **LinkOut**
        are not going to be covered in today's class. These links are
        most often used by publishers, medical libraries and clinicians.
        However, the latest **MY NCBI** (formerly Cubby) feature will be
        partially reviewed.

II. Searching PubMed

```{=html}
<!-- -->
```
A.  Basic Searching \[ppt slides 12-16\]

-   The **Query Box** is where you enter your search terms.

-   Below the query box are the **Feature Tabs**: **Limits**;
    **Preview/Index**; **History**; **Clipboard** and **Details.**

-   Let's look at a typical question you may be asked in your public
    library that may necessitate a PubMed search.

    -   *"I was exposed to asbestos for years at the paper mill. Can
        that cause gastrointestinal cancer?"*

    -   Enter the terms: **asbestos gastrointestinal cancer**

        *Your talking points:*

        -   *Tell the class that PubMed automatically ANDs words and
            phrases together. Your results should be approximately 222
            "hits"*

        -   *Let's discuss our subject terms. Can anyone think of a
            synonym for "cancer"? -- neoplasm, malignancy, carcinoma,
            etc. We used to have to try to think of all synonyms to make
            sure we embraced all significant terms (asbestos AND
            gastrointestinal AND (cancer OR neoplasm OR malignancy OR
            carcinoma...).*

        -   *You don't have to do that in PubMed.*

        -   *Let's take a look at the **Details** tab (click to show).
            The Details tab shows you how PubMed actually did the
            search.*

        -   *Cancer is a synonym for Neoplasms and Gastrointestinal
            Cancer is a synonym for Gastrointestinal Neoplasms. PubMed
            incorporated the MeSH term, Gastrointestinal Neoplasms in to
            our search.*

        -   *You do not have to try to think of all the possible terms
            to search, PubMed automatically takes your term and "maps"
            it to the correct subject heading!*

        -   *The **Details** tab should be your "best friend." This
            feature shows you how PubMed translated your search terms
            and can help identify errors.*

-   Now direct the class back to the search results screen. The first
    problem with these results is that they are all the foreign language
    articles.

    -   *Start pointing out the foreign language articles. Show them the
        Italian, Japanese, and German citations. These are the citations
        with square brackets around the title. Ask the class, "Do we
        want these?" Hopefully, they will answer, "No".*

    -   *Make the point that you want to eliminate these foreign
        language citations and that this elimination can be done quickly
        via the **Limits** tab.*

B.  Limits Tab \[ppt slides 17-20\]

-   Describe the various limits. Remind the class that the database is
    going back to the early 1950s.

    -   For class interaction, as the class how far back they want to
        search.

        -   *Here, participants usually ask if they can limit to
            [full-text]{.underline}, [abstracts]{.underline} or
            [consumer health journals]{.underline}. You can do this but
            it is important to point out that :*

            *1) The full-text links are primarily for the life sciences
            journals and you automatically exclude good articles. Let
            them know that you are going go over document delivery -- so
            there are ways to get the full text.*

            *2) There are only 17 consumer health journals out of 5,000
            journals! Ask them, do they really want to limit and miss a
            quality review article.*

            *3) The box on the Limits screen lets you limit to abstract
            but again you may automatically exclude good articles or
            even free-full text articles that don't have an author
            abstract.*

-   Explain that Limits, other than Language and Year, should not be
    used if you want to capture MEDLINE records in process or publisher
    records.

    -   Based on the class input, set the **Date** and Language to
        **English** and click on **Go**.

C.  Search Results \[ppt slides 21-25\]

-   Review the search results options.

    -   Point out the ones that show just the basic bibliographic data,
        e.g., *Morgan RW*, ones that have abstracts, and the ones that
        are full-text, e.g., *Parent ME*.

-   Explain the **Action Bar** options:

    -   The **Retrieval tab** shows: 1) **All:222** which is the total
        number of citations found and right below this, PubMed will list
        the first 20 citations and you can use the **Page** button to
        select the next batch of citations to view.

    -   The default Review filter displays the number of review articles
        -- these are articles (or books) published after examination of
        published material on a subject. It may be comprehensive to
        various degrees and the time range of material scrutinized may
        be broad or narrow, but the reviews are often reviews of the
        current literature.

    -   The **Show** pull-down menu lets you change the default of 20
        citations to just 5 per page or up to 500 per page.

        *Point out the following:*

        -   *This is option comes in very handy when you want to print
            more than 20 citations which is the default display.*

    -   The retrieval (or citations) display in a "last in/first out
        order" by date added to PubMed -- this is called the **Entrez
        Date** -- which is not to be confused with the Publication Date.
        To change the sort order of the citations, use the **Sort**
        pull-down menu to select from Author, Journal or Pub Date.

    -   The **Send to** pull-down lets you **print**, **save**,
        **e-mail**, **order** full text and use the managing feature,
        **Clipboard**.

    -   At this point, have the students select 4 to 5 citations that
        look interesting to them. Use the check-box to select these
        items. Show how to view Abstract of one citation, selected
        citations and all citation.

        *Don't forget to point out:*

        -   *You can change the display format using the Summary
            pull-down menu. Other suggested display options are Abstract
            and Citation. The Summary format includes the Author
            Name(s), Title of the Article, Source, Links and the
            Abstract/Free Full text icons.*

    -   While showing the Abstract and Citation formats, point out the
        links to the publisher's website. Explain that these are
        typically only available to subscribers and will likely require
        a username/password. Remind them that free full-text articles
        are easy to spot because they are the ones with the colored
        paper icons.

-   **Document Delivery:** Take time out here to discuss document
    delivery (how to get the full-text copy of articles).

    -   Describe how Loansome Doc works -- uses an NN/LM member
        (nnlm.gov/members) to get full text articles. Notice some NN/LM
        members provide Loansome Doc service to the public.

        *You should also mention:*

        -   *Loansome Doc may not be offered by a number of libraries
            who have switched to document delivery systems like the ISO
            Protocol so you may want to work individually with your
            local hospital librarian.*

D.  Links: \[ppt slides 26-28\]

-   The **Related Articles** links you to a pre-formulated search set
    (an algorithm that compares words in the title, the abstract and
    Subject Headings to create a set of closely related citations).

    -   If you find an article that is perfect, consider using this
        link.

        -   *When you select this link, you will lose your Limits, such
            as English and the Date range.*

-   **LinkOut**: This option connects you to other resources, e.g.
    publishers, organizations, NLM resources and more.

-   **Clipboard**: Explain that this feature helps you manage retrieval
    of citations while searching.

    -   Another way to phrase this: *"The Clipboard helps you keep track
        of the good ones and allows you to temporarily store citations
        while you continue searching. Sometimes you want to do a second
        search or refine your search, but you want to save what you have
        already found. Use the Clipboard to do this"*

    -   Select at least 4-5 citations and add them to the Clipboard.

    -   Make sure you point out that the Clipboard hold records for up
        to 8 hours, the color of the number before a record changes once
        it is added to the Clipboard.

        -   **Demonstrate the advantage of the Clipboard:** Mention that
            sometimes one gets busy (the phone rings or you get called
            away from the desk). And, even if the PubMed page is closed
            and you re-open the page (as long as you are on the same
            computer), the citations you placed in the Clipboard will
            still be there. To illustrate, close the browser and re-open
            it to find the saved citations on the Clipboard. This
            usually impresses the students.

E.  Combination Searching \[ppt slides 29-31\]

-   Combination searching simply means that you are entering multiple
    terms or types of terms to retrieve a specific set of citations.

-   Let's use the search: *"There was an article a few years ago (maybe
    4 -- 5 years ago) by Dr. Keys about cervical cancer treatment. It
    was published in the New England Journal of Medicine. Can you find
    this?"*

    -   The search terms to enter are **keys cervical cancer new england
        journal of medicine** -- they consist of the author's last name,
        subject and journal title.

        *Highlight the following:*

        -   *Ask the class: "How will PubMed know what to do?" You
            should retrieve 1 citation.*

        -   *At this point, you may want to highlight the **full journal
            title mouse over**.*

    -   Click on the Author link to view the abstract and then explain
        the NEJM publisher's link.

    -   Again, highlight the usefulness of the **Details** tab *(click
        to show)* and explain how PubMed knew that *New England Journal
        of Medicine* was a journal title and why it searched for Keys in
        all fields.

        -   *Here, if there is time, you can do two searches illustrate
            how PubMed translates terms:*

            *1) Enter **new england journal medicine** and click on
            **Details** tab.*

            *2) Enter **keys hm** and click on **Details** tab.*

-   Go over quickly the **Automatic Term Mapping** process. Highlight
    that PubMed matches the terms in the query box against three
    translation tables:

    -   1\) MeSH (Medical Subject Headings)

    -   2\) Journal Titles

    -   3\) Author Names

-   Beware of how you search -- **natural language searching** is not
    efficient!

    -   Let's say we want to *"look up articles describing the use of
        antiperspirants on foot blisters"*

    -   Using natural language, you would enter: ***antiperspirants as a
        cure for blisters on the feet --*** the result is 0 citations.

        -   *Go to **Details** to show PubMed search **as a** as an
            author because it fit the format of lastname firstinitial.*

    -   A better search for PubMed is to use just the relevant terms,
        which are: ***antiperspirant feet --*** review the search
        results, should be approx. 6 citations.

F.  Advanced Searching \[ppt slides 31-34\]

-   An advanced (or complex search strategy) makes use of field
    descriptors, such as the author field, and/or Boolean connectors.
    Boolean connectors in PubMed are AND, OR, and NOT.

-   There are several ways to construct a complex search strategy but
    one of the easiest methods is to use the **Preview/Index** tab.

    -   To review this feature, we will construct the following search:
        "*My child has celiac disease. I understand that Dr. Chin has
        done research on the neurological aspects of this and it was
        published in the Journal Neurology"*

    -   First, show what happens when you enter: ***chin neurology
        celiac disease*** -- the result is 0 citations!

        *Again, go into the **Details** tab and point out:*

        -   ***chin** was mapped to the MeSH term instead of the
            author's name.*

        -   ***neurology** was searched as a MeSH term instead of
            journal title.*

        -   *What do we do? We need an advanced search option so that we
            can search by particular field. In PubMed we look for
            Preview/Index (I realize this is not intuitive )*

    -   Click on the **Preview/Index** tab and explain that this feature
        is really two features in one:

        -   *1) The **Preview** feature, the top portion of the screen,
            shows your **Most Recent Queries** -- your last 3 searches.
            You can still enter terms in the query box and select **Go**
            to run your search view the search results. Or, click on
            **Preview** to view the number of items found first and then
            click on the results number to view the search results.*

        -   *2) The **Index** option**,** bottom half of screen, lets
            you construct searches using specific fields and Boolean
            connectors.*

    -   Scroll down to the Index portion of the screen and do the
        following:

        1.  Enter ***chin*** in the query box.

        2.  Select **Author** from the **All Fields** pull-down menu.

        3.  Click on **Preview** -- Point to the query box to see search
            term.

        4.  Next, enter ***neurology*** in the query box, click on the
            **All Fields** pull-down menu and select **Journal** and
            click on the **AND** button.

        5.  Lastly, enter ***celiac disease*** in the query box, select
            **All Fields**, and click on **Preview**.

        6.  In the **Preview** section of the screen, point out the
            constructed search strategy and the results link. Click on
            the results link -- there are 2 citations.

G.  Boolean Searching \[ppt slides 35-37\]

-   The default in PubMed is to AND but PubMed does allow you to use OR
    and NOT. You could conduct this search using the **Preview/Index**
    tab or just enter search terms in the query box using the Boolean
    connectors.

    -   Let's try these in the following search question using the
        Boolean connectors: "I am looking for a study published recently
        in either JAMA or in the New England Journal of Medicine on the
        effectiveness of a "virtual" colonoscopy."

    -   Enter the terms: ***(new england journal of medicine OR jama)
        AND virtual colonoscopy -- should get approximately 20
        citations.***

        -   *You may want to explain in more detail how you created the
            first search set of the journal titles **new england journal
            of medicine OR jama** and to force PubMed to search this as
            a set, you need to enclose it in parentheses ().*

        -   *Next, you just AND this with your subject terms, **virtual
            colonoscopy** and click **Go**.*

H.  History \[ppt slides 38-39\]

-   The History tab keeps track of all your searches for the current
    session -- point to the instructions displayed on the screen.

    -   It will keep searches for 8 hours just like the Clipboard.

    -   You can use the History to combine search sets using Boolean
        connectors, e.g., #2 and #6.

    -   You can also use the History to select and save searches in the
        MY NCBI feature.

III. Journals Database \[ppt slides 40-41\]

-   The Journals Database lets you search for a journal title and
    provides details about the publication, such as publisher, frequency
    and indexing status in MEDLINE.

    -   Sometimes when you perform a search, it is difficult to
        determine the full Journal name (or the mouse over feature isn't
        quite working. ) You may see something like:

        -   *Methods Find Exp Clin Pharmacol BJOG*

        -   *J Bone Miner Res J Womens Health Gend Based Med Calcif
            Tissue Int*

    -   When requesting an ILL, you need the full journal title and
        typically, the ISSN. use the Journals Database for this

    -   Click on **Journals Database** and link from the black bar above
        the query box or from the blue sidebar -- point out both
        options.

    -   Here, use the example that you are trying to find the full title
        of *Arch Dis Child* enter this term in the query box. **Don't
        click on GO yet!**

        -   *Before you click on GO, take this time to point out the
            Feature Tab bar for the Journals database.*

        -   *Show that the **Limits** and **Preview/Index** tabs operate
            the same as in PubMed but the search field options are
            different.*

        -   *You may want also to let them know that there is a separate
            **History** for each Entrez database.*

    -   Now, click on GO to show the results.

    -   Point out the **Suggestions** portion -- in case you don't find
        the title listed on the search results screen.

    -   Clicking on the journal title displays more detailed information
        about the journal, such as the publication start year and the
        publisher.

    -   To search for articles in PubMed, click on the **Links** and
        select the database to search, either **PubMed** or **Single
        Citation Matcher**.

IV. Single Citation Matcher \[ppt slides 42-43\]

-   This is the greatest thing since sliced bread! Sometimes (often) a
    patron will request an article but, unfortunately, does not have the
    complete citation. They may be missing page numbers, the volume or
    the author. The **Single Citation Matcher** will allow you to enter
    any part of a citation and find the article with the complete
    citation.

    -   Point out the instructions at the bottom of the screen.

    -   Let's use the example: *"I know there was an article published
        in 2001 in JAMA about the quality of information on the
        Internet. The researchers used search engines to retrieve health
        information in English and Spanish. There were a bunch of
        authors, but I don't know their names. I do know that the words
        English and Spanish were in the title. Can you find this?"*

    -   Enter the terms in the appropriate fields: enter ***JAMA*** in
        the Journal box, **2001** Date box, and ***english**
        **spanish*** in the Title Words box.

    -   Your results will be 1 citation: *Health information on the
        Internet: accessibility, quality, and readability in English and
        Spanish. JAMA. 2001 May 23-30;285(20):2612-21*

V.  MY NCBI: Saved Searches \[ppt slides 44-48\]

-   PubMed recently replaced the "Cubby" with an enhanced new feature,
    **My NCBI**.

-   Use **My NCBI** to:

    -   Save searches;

    -   Set up automatic email updates;

    -   Display links to web resources (LinkOut);

    -   Select filters that customize and group your search results.

    -   One of the most useful features of My NCBI enables PubMed
        searchers to set up automatic email updates of stored searches.
        You stay up-to-date with the latest articles in your areas of
        interest. This feature is good for librarians as well as
        patrons.

-   For this class, we will only cover how to save searches and create
    automatic email updates. The PubMed Help can provide additional
    information about all of the features in My NCBI.

    *Make the following points:*

    -   *Before you run a search, you will need to set up a **My NCBI**
        account and log in. If you have an existing Cubby account and
        can still remember your ID and password, this will work.
        Otherwise, follow the instructions under the My NCBI link (point
        the class to this link).*

    -   *There is no charge, the User Name and Password are created by
        the user, and the hardest part of this process is remembering
        the two!*

    -   *In addition, they will be asked to enter an e-mail address.
        This e-mail address is used for both [automatic e-mail
        updates](http://www.ncbi.nlm.nih.gov/entrez/query/static/help/pmhelp.html#MyNCBISavedSearches%23MyNCBISavedSearches)
        and the [Send to
        E-mail](http://www.ncbi.nlm.nih.gov/entrez/query/static/help/pmhelp.html#E-mail%23E-mail)
        feature in PubMed.*

    ```{=html}
    <!-- -->
    ```
    -   After logging in (*use your ID and Password*), run a search
        without date limits in PubMed. Highlight and click on the **Save
        Search** link to the right of the query box.

    -   A separate window will open to connect you to My NCBI Save
        Searches.

        -   *Points to make with the class:*

        -   *Give each of your saved searches a meaningful name! Only
            save the good ones!*

        -   *If you want the search results sent to you automatically
            via email, choose "yes". If you choose "no", the search
            strategy will be saved and you can go into My NCBI anytime
            to update it manually.*

        -   *If you didn't sign on to My NCBI, you will be prompted.
            Also, if you were a Cubby user, you can click on the "My
            Saved Searches" page and use the "Details" column to change
            your saved searches to automatic email update searches.*

        -   *Very Important: If you are using PubMed at a public or
            shared computer such as in a clinic, hospital workroom, or
            Your Library, don't forget to click **Sign Out** when you
            have completed your search session.*

VI. Break (15 minutes)

VII. Class Exercises \[ppt slide 49\]

-   Have students pair up and work on the class exercises (some may not
    want to -- this is OK).

    *There are a couple of options for how you would want to run the
    Exercises portion of the class:*

    -   *#1: Give the students a few minutes to work on the first
        exercise, and when one "team" has the answer, look at their
        screen to ensure they did the question correctly. After a few
        more minutes, have them explain to the rest of the class how
        they found the answer.*

    -   *#2: Allow 30 minutes for the exercises and after 20 minutes
        stop them and then go through each question with the class. You
        can ask for volunteers to answer each question -- this is a good
        exercise because at this point you can congratulate them for the
        correct (or suggested) search strategy or explain to them and
        the entire class a "more accurate method" for developing the
        search strategy.*

    -   *#3: Let the students alone. Use the time to walk around and
        help each student or team individually.*

**Question #1:** I heard there was a study done on the stretchiness of
various cheeses when they melt. Find this article.

> **Suggested Answer:** cheese stretch
>
> They should find the citation: Test for measuring the stretchability
> of melted cheese. J Dairy Sci. 2002 Dec;85(12):3539-45.

**Question #2:** My child is 10. The orthodontist wants him to use an
electric toothbrush while he is wearing braces. I don't see why he can't
use a \$2.00 toothbrush rather than a \$50 electric toothbrush. Are
there any studies proving that electric toothbrushes are better?

> **Suggested Answer:** manual electric toothbrush Limit: child (6-12)
>
> Result: about 15 citations

**Question #3:** My doctor wants to use a uterine balloon for my heavy
periods. I never heard of such a thing. Can you tell me if there has
been any research on using this?

> **Suggested Answer:** uterine balloon
>
> Result: 3890 articles...Browse the first page, several pertinent
> articles.
>
> Note: Some students will have difficulty with this because they will
> still have the "child" limit from the previous question. This reminds
> them to be sure they check the limits.

**Question #4:** I heard that drinking skim milk causes more severe
acne. Are there any studies that talk about this?

> **Suggested Answer:** skim milk acne
>
> Result: Just one article about this: Adebamowo CA, Spiegelman D, Danby
> FW, Frazier AL, Willett WC, Holmes MD. High school dietary dairy
> intake and teenage acne. J Am Acad Dermatol. 2005 Feb;52(2):207-14.

**Question #5:** My son is adopted from Korea. He has a skin condition
called Nevus of Ota, which is disfiguring. I want to have it removed,
but the dermatologist here said he has read about it, but never actually
removed it before. I'm wondering if there is a doctor in the US who has
done this surgery?

> **Suggested Answer:** nevus of ota surgery
>
> Results: The resulting articles seem to be written by non-US doctors
> because this condition is found primarily in Asians, so most research
> has been done by Asians. To find a doctor in the United State, you
> will need to search for US doctors. (BTW, this is an actual reference
> questions I had in my public library)
>
> Revised search: Try adding USA to the search. In the field describing
> the research institution, the country is typically listed. US research
> has typically "USA" in this field. Note: If you search using United
> States it will do a MeSH search and this is not what you are looking
> for.

**Question #6:** Is it true that antiperspirants cause breast cancer? I
got an email saying it does.

> **Suggested Answer:** antiperspirants breast cancer Results: about 4

**Question #7:** Someone named Burns wrote an article about Carl Sagan
in the journal Nature. Can you find this?

> **Suggested Answer:** Single Citation Matcher works great for this.
> Journal: Nature / Author: Burns / Title words: Carl Sagan. Can also do
> field searching.
>
> Result: Carl Sagan (1934-96)\
> Nature. 1997 Jan 30;385(6615):400. No abstract available.

**Question #8:** What is the ISSN and title for this journal: Lasers
Surg Med?

> **Suggested Answer:** Use the Journals Database and enter ***lasers
> surg med*** in the query box. The ISSN is 0196-8092 and the full title
> is: Lasers in surgery and medicine.

**Question #9:** I heard that the early polio vaccine was contaminated
with a monkey virus, and that's how AIDS got started. My question is
what is the name of this virus and does it cause AIDS?

> **Suggested Answer:** polio vaccine monkey
>
> Results: about 20 articles

**Question #10:** What is better at relieving pain in
children...ibuprofen (Motrin) or acetaminophen (Tylenol)? I want to see
a study that shows which is better.

> **Suggested Answer:** pain management AND ibuprofen AND acetaminophen
>
> Limits: clinical trials / all child (0-18)
