Some gynecological cancers linked genetically to salivary gland malignancy

July 9, 2009

New studies reveal a genetic rearrangement involving the oncogene mammalian mastermind like 2 (MAML2) in some cancers of the cervix and breast, relating them genetically to mucoepidermoid carcinoma of the salivary glands and distinguishing them from squamous cell carcinomas of these tissues.

Therefore, they would demand careful pathological analysis and different therapeutic strategies.

A 2006 study associated this fusion gene of MAML2 with favorable prognosis in salivary cancer.

Confirmed: Contrast media can be deadly for kidney patients

July 8, 2009

Contrast-enhanced coronary angiography causes adverse events including death in patients with kidney disease. As many as one in ten patients experience a bad effect of some kind.

This new information comes from a randomized multicenter trial that compared people who underwent angiography using one of two iodinated contrast agents, iopamidol or iodixinol, with others who did not have angiography.

Adding fuel to a long-standing controversy about contrast-induced nephropathy, the report appears in the Clinical Journal of the American Society of Nephrology.

Lessons to improve your success on SearchMedica, drawn from a genuine search

Want to find a graph, rather than words?

Alas, someone’s search on the query graph of FSH and LH levels during the menstrual cycle was destined for failure.

RESULT: Follicular Phase Dynamics With Combined Aromatase Inhibitor and Follicle Stimulating Hormone Treatment
Journal of Clinical Endocrinology & Metabolism

At first glance, we thought it would be a challenge to find such a graph. But thanks to a little strategizing, we retrieved it on the first attempt.

TIP: SearchMedica is not designed to search for images, because it looks for the frequency of words in text. Finding specific images would require searching for captions. And captions, after all, don’t include much text.

However, it’s still possible to find graphs by thinking about what kind of article would include them.

Here’s what we did:

1. Eliminate all “generic” words and list the most important terms first. The key is to think of relevant words most likely to appear often in an article that would contain the information you want.

In the original query, “graph” wouldn’t help the search at all, because our target article is unlikely to have numerous occurrences of that word in its text. “Of,” “the,” and “during” are just potentially confounding clutter.

We chose the query FSH LH “menstrual cycle”.

2. Un-click the option “Prioritize results by publication date.” Normal menstrual cycles haven’t changed over the course of recent history, so almost any old article will do the trick. We want to make relevance to the search term—not publication date—the most important search criterion in this case. Un-clicking “publication date” accomplishes that.

3. Given a choice, select the PDF version of the full text if you’re looking for images. Publishers often don’t include images in the HTML versions of their articles. When they do, the graphs are often reached via separate links. (This is another reason they’re difficult to find in SearchMedica searches. The captions may not even appear in the main HTML text).

Here’s what we found:

RESULT: Menopause Transition: Annual Changes in Serum Hormonal Patterns Over the Menstrual Cycle in Women During a Nine-Year Period Prior to Menopause
Journal of Clinical Endocrinology & Metabolism

The graph of normal FSH and LH levels over the menstrual cycle appears in the top two panels of Figure 3 on page 2768 of this article. Be certain to choose “Full Text (PDF)” in the upper right column of the screen on which the abstract appears.

The filled symbols in the chart represent a normal ovarian cycle.


How often does a negotiator avert gunfire, in real life?

July 7, 2009

It was a tense and potentially violent few days in the Mental/Nervous System tab on SearchMedica. The statistics reveal that there were many searches related to violent crisis in the past week. But they can’t tell us why.

A top search term one day was “crisis intervention.”

It points up a new study testing a hypothesis raised every evening on TV—that professional negotiators actually reduce the risk that someone will get hurt when a mentally ill person threatens the public peace.

Do police officers trained in crisis intervention actually restrain the actions of SWAT teams (and the resulting risk of injuries)?

More than 400 police crisis intervention teams have been formed since the effort was pioneered in Memphis 20 years ago, but very few studies have examined their effectiveness.

(Numerous related articles in the same issue of the journal appear in the list of search results because the journal has prominently linked the study about SWAT teams to those articles on its own Web site.)

Automated MRI method makes Alzheimer’s visible before it’s obvious

July 1, 2009

The large number recent searches on the term Alzheimer MRI are evidence of tremendous curiosity about a new noninvasive diagnostic method, reported recently in Brain.

(The full text of the report currently heads the list of results.)

Software tools divide MRI scans of the brain into anatomically meaningful sections and quantify tissue atrophy, allowing early noninvasive diagnosis of both mild cognitive impairment (MCI) and Alzheimer’s disease. The report is from the Alzheimer’s Disease Neuroimaging Initiative, headquartered at Massachusetts General Hospital.

Three anatomical measures—entorhinal cortex thickness, hippocampal volume, and supramarginal thickness—correlate significantly and consistently with neuropsychological and CSF measures of Alzheimer’s disease.

RESULT: Automated MRI measures identify individuals with mild cognitive impairment and Alzheimer’s disease
Brain

Scroll down the same search results page for another study suggesting that MRI measures of brain atrophy may be particularly useful for predicting Alzheimer’s in highly educated patients (among whom high cognitive reserve can complicate the diagnosis).

RESULT: Early diagnosis of Alzheimer’s disease using cortical thickness: impact of cognitive reserve

“I am asking for Cushing’s ulcer not Cushing’s syndrome,” said the feedback message. The search term, not surprisingly, was Cushing’s ulcer.

RESULT: Effect of Calcipotriol Plus Hydrocortisone Ointment on the Adrenal Hormone Balance and Calcium Metabolism in Patients With Psoriasis Vulgaris on the Face and Skin Folds
ClinicalTrials.gov

TIP: First, why did this result show up at all?

There’s a clue in the blurb beneath the article title, where the search terms appear in bold:

… fragility of skin veins ichthyosis acne rosacea
ulcers and wounds … Clinical signs or symptoms
of Cushing´s disease or Addison’s disease …

This result appeared first because it was the item posted online most recently that was relevant to the search term.

There are several possible strategies for narrowing the results to the ones relevant to this search term:

1. Put the search term inside quotation marks: “Cushing’s ulcer”

2. Use the word NOT to eliminate unwanted terms: Cushing’s ulcer NOT syndrome NOT disease.

3. De-select “Prioritize results by publication date” just beneath the search box. This will limit the search criterion to relevance only: Cushing’s ulcer [with “prioritize by date” un-clicked].

(But bear in mind that choosing this option will probably offer many results that are quite old. In this search, the top result is from 1982.)

Remember that it’s always possible to target your search further using the article categories just above the results list, such as Patient Education and Research/Reviews.


Teen depression diagnosis, treatment declined in wake of FDA warning

June 30, 2009

As predicted, diagnosis and treatment of depression have declined after FDA warnings about suicide risk associated with antidepressant treatment of children, teens, and young adults.

“Diagnosing decreases persist,” says the abstract. “Substitute care did not compensate.”

We still need to figure out what to do for teens with serious depression.

RESULT: Persisting Decline in Depression Treatment After FDA Warnings

TIP: First, there’s no journal called “Couples Therapy Review”, as far as we can tell. So this isn’t a journal search.

Adding “2009″ is unnecessary because SearchMedica results are ranked according to publication date. So articles from 2009 should rise near the top of the list in any case.

You can target a search for reviews by looking in the article category Research/Reviews.

We tried this category using the search term couples therapy. Looking at 2009 results, the search offers a few book reviews and this one study.

The authors believe their results can be generalized to countries with universal access to health care and active perinatal programs.

More than half of the babies had lung or retinal complications. About one in 10 had neurological problems.

Scroll down slightly to find a related study from the US that is troubling to both pediatricians and parents.

A “significant proportion” of very low birth weight infants develop cerebral palsy many months after they have left the hospital apparently in the clear, according to a recent study from the US.
