In this video, scientists with the company Oxitec explain how they engineered mosquitoes to carry a "lethality" gene that prevents mosquito larvae from growing into adults unless they are fed the antibiotic tetracycline. The genetically modified (GM) mosquitoes were first produced in 2002 and bred in the lab to give rise to a colony of mosquitoes all dependent on tetracycline. This antibiotic - the antidote to the lethality gene - is available to the mosquitoes in the lab, but not in the wild. In 2015, male mosquitoes from this GM colony were released in some areas of Brazil to help stop the spread of Zika virus. When male GM-mosquitoes mate with non-GM females in the wild, they pass on the lethality gene to the offspring who, without access to tetracycline, die before growing into adults.

I am a veterinarian and a toxicologist. My comments are based on the nine toxicology books (seven veterinary) I have in my office tonight, ranging from 1984 through 2008 publication dates.
There is a widespread unwillingness to go over the mechanism of formation of the toxic metabolite NAPBQI, the subject of your problem. Only one of them ventures a description (Osweiler, 1996), and his is an outline. He favors your reaction scheme, which he describes as an N-hydroxylation followed by a spontaneous rearrangement to NAPBQI. It makes sense, and I can draw the bond flow, but this is a 1996 text, and the 2000, 2006 texts on small animal toxicology don’t describe it at this level. I’m guessing because it is not known, and other aspects are more central to curing the cat. Your case got this right. It is hard to look it up, at least in my nine texts!
I have lectured on this toxicity in cats, and have 105–115 students that are 3rd-year professionals each fall. In the 5–6 times I’ve given this to 500+ students (total), I have never been asked to diagram or describe the reaction. This is fortunate, because it is described as an oxidation in the other texts. Only Osweiler is willing to guess (in print) of all our toxicologists. The rest of us are willing to say this is probably the reaction, or at least that we can’t really argue against it coherently.
I’m guessing that hepatotoxicity was emphasized because humans and almost all other species except cats get it.
Different from your case is that cats get methemoglobinemia, which is an oxidation of hemoglobin so that it can’t carry oxygen. Most cats don’t show liver toxicity, unless they are resistant to methemoglobinemia. Cat hemoglobin is more sensitive than dogs or humans because it has more available sulfhydryls to oxidize, and cats are much more sensitive than dogs to Tylenol toxicity. One-half of a tablet and extra strength Tylenol would have been more than enough. Your case was correct in that. The reaction of the mom is typical, because this toxicity and its extent are not well known.
When about one-third of the hemoglobin is oxidized cats show clinical signs, which are cyanosis, apathy, and muddy mucous membranes. Blood is usually chocolate brown, so the veterinarian was wise to draw it in your case. Explaining it to the client is a nice touch, but it doesn’t happen in all cases.
Cats often present with some thrashing about (not mentioned in your case, or most texts), methemoglobinemia, apathy or depression, and muddy mucous membranes (chocolate brown) that are hard to see unless you know where to look. Thus, your presentation was typical, not really all that mild. If they’ve had Tylenol and have clinical signs, treatment is needed, and that was well done in this case.
The prognosis is fair to good with optimal treatment and the antidote, n-acetyl cysteine, which replaces glutathione in NPPBQI detoxification and favors synthesis of more glutathione, which does the same. Again, explaining that the antidote restarts what the cat would have done if it didn’t run out of glutathione is useful (any teachable moment is cool to capitalize on), but it doesn’t occur in all cases.
We do treat with charcoal to tie up remaining Tylenol, but your case was not about this, and didn’t have it as a learning objective.

I used this case in two sections of my non-major university course titled "Biology for Living." This was my first attempt at using or incorporating a case study into my courses. The students seemed very receptive to the idea. After I gave them part one of the study, they asked lots of questions about the fish. It got them very interested. Most (if not all) had never heard of the coelacanth. I added to the pictures by pulling up photos of coelacanths on the computer and projecting them for the students to see during each part. I followed up the case with a homework assignment. They had to report on recent research or happenings with regard to the coelacanth fish. -----------------------------

This case reminded me of the "case" of a child here in Houston having his arm swatted off by a tiger. I rewrote the case using excerpts from newspaper articles published about the accident and the recovery of the child. These included interviews with the physicians involved in the implantation. I renamed the case "The Tiger and the Tot" and wrote it as an interrupted case. The students worked in groups for 15 minutes, then we discussed the case as a group.
I used some of the questions from the original case, but since I offer this earlier in the Anatomy and Physiology course than did the original author, some of the questions did not apply. Some of my students remembered this event and I think that helped stir interest.

I’ve used this case with my Rhetoric and Science students to illustrate the differences between the persuasive power of advertising and the kinds of arguments made with scientific data. These students had been drilled about appropriate uses of data, although not all of them had taken college level courses in chemistry.
This evening, I noticed the following article about lawsuits against the Coca-Cola Corporation over its marketing of VitaminWater as a “healthy alternative” to sodas; thought you might find it an interesting addition to the case: http://www.medicalnewstoday.com/articles/135816.php.

I found this case to be a very effective way to teach the Scientific Method to a group of non-major biology students. This is the first case I have taught since attending a Chautauqua Short Course this past summer with Kipp Herreid, and it worked extremely well. I asked the 23 students to self-select themselves into groups of 3 or 4 and then worked through the case with class discussion following each of Parts I–III. We did not have enough time to complete part IV in the 50 minute time frame.
I found that the case questions yielded some interesting and creative solutions. In many cases it offered up a springboard for discussion of local migration and PCB contamination issues. Students also asked about PCB contamination in Great Lakes Fish and other pertinent topics. This is one of the many topics that will be addressed throughout the semester.
Rather than use the last few minutes of class on Part IV (though it seems a valuable thing to do), we discussed the advantages and shortfalls of the Scientific Method. Learning the Scientific Method through case participation will likely help the students complete future labs, for which they will need to construct hypotheses, design experiments, etc.
I found the referenced Nature (2003) article to be helpful and did not use any additional resources in class given the time constraint.

I recently used the case study "Memory Loss in Mice" for one of my courses and thought that you might be interested in some evaluation and feedback on how I used the case.
I am currently teaching an upper level undergraduate biology course entitled "Molecular Basis of Disease." The course is being taught over simultaneous videoteleconferencing between Shaw University in Raleigh, NC and UNC—Chapel Hill in Chapel Hill, NC. The distance education studios are equipped with VTC equipment and SMARTBoards connected through Netmeeting. We have 4 students at Shaw and 18 students at UNC enrolled in the course. I am the instructor at Shaw University and my collegue Dr. Jory Weintraub is the instructor at UNC. We each lead discussions on various topics looking at the molecular mechanisms of disease and we have included one session on Research Methods and Animal Models. To introduce this topic, I used your case to get students thinking about how to interpret scientific data, draw conclusions, and describe how animals are used in biomedical research. This simple case provided much discussion and interaction between students at both sites. Although I happened to use it in an upper level undergraduate course, it certainly could be used in either undergrad or grad level courses. Thank you for providing a great case for our course!
I am currently implementing other cases from the Buffalo Case Study site as well as writing my own that I can hopefully share with others at the Buffalo site.

We used this case on the first day of class as an introduction to the role of ethics in environmental science. It worked well because students were able to be active right away and to identify ethical issues that we could then discuss more in class. We followed the teaching notes reasonably well, and I think that worked out. Thank you! -----------------------------

I used this case in a cooperative experience with a middle school science teacher and a Chatham colleague. We broke the case into smaller “chunks” that would fit in a 40-minute class period. At the end of each chunk we raised questions for the students to consider, and they wrote responses in a science journal. We created charts to help the students organize information and their answers. We also located and designed activities that corresponded to sections of the case. For example, when the case mentioned dissolved oxygen, we had the students do a hands-on activity to explore the concept of dissolved oxygen. We also used the 5E Model of Inquiry paying particular attention to 2 of the 5 essential features of application and extension. [Editor‘s Note: see http://www1.mcps.k12.md.us/curriculum/science/instr/teaching5Es.htm for a brief description of this model.] Through the process of exploring the case, students refined their initial hypothesis and cited the evidence for their decisions (again, all of this was recorded in their journals). At the end of the case study, the students had a field trip to an area called Nine Mile Run which empties into the Monongahela River. It was, in the past, a source of contamination and a ”fish kill“ location. It has since been cleaned up and no longer serves as a pollution source.
By taking this case in smaller chunks and exploring vocabulary when necessary, we felt the case was an excellent way to engage middle school students in the process of inquiry.
There is an excellent book, And the Waters Turned to Blood: The Ultimate Biological Threat by K. Baker (Simon and Shuster, 1997), that gives more context to the case and some interesting information about the health effects of this study on the scientists who conducted the research. Another book that might be of interest is one we used by Jean Craighead George, Who Really Killed Cock Robin? An Ecological Mystery published by Harper Collins Children’s Books in 1991.

I have used this case with my Organic Chemistry II class. Many of my students are pre-pharmacy, so having a medical tie-in increases the students’ interest in the case. The case also forces the students to recall material previously learned (E/Z designations) while learning new concepts (such as lactam/lactim). I allow the students to form groups and work together outside of class. They submit their answers to the questions which count toward part of their grade on their first exam. -----------------------------

I adapted the case study, “The Chemistry of Cooley’s Anemia,” for my Basic Biochemistry course consisting of juniors and seniors. The students, in groups of 3–6, were given bits of information allowing them to solve for the disease and related questions using the internet and their biochemistry book. The class reconvened the last 15 minutes of class and chatted about the ethical issues pertinent to the case. I also introduced the concept of collaborative efforts in science as a precursor to drug discovery. It was a hit! I plan on using three additional case studies throughout the semester. -----------------------------

This is an interesting case. Typical cases of crocidolite (very small amphibole; deposited in deep lung) were seen in daughters whose fathers worked with ship insulation of crocidolite asbestos from South Africa (it is called “Cape Blue” crocidolite). The fathers came home and whacked their shirts on the porch as their daughters were waiting to hug them. Twenty-five to 40 years later, the girls, now mothers, developed mesothelioma and often died.
Until recently, crocidolite was the only asbestos with direct cause from the asbestos alone. Recently, erionite asbestos (not mentioned in your research) was found to be the source of additional lung cancers. Chrysotile is the source of more than 80% of all asbestos in the U.S. It is serpentine and therefore too curvy to deposit in sufficient quantity to work its way into the thoracic mesothelium. Amosite asbestos is the right shape, but not small enough for maximum deposition, as is tremolite. Grunerite is too large for maximum deposition and not as durable as amosite, chrysotile or crocidolite asbestos.
To answer your questions, if I were an expert witness, or jury member, I’d like to know what kind of asbestos. Chrysotile asbestos for this chain of toxicity would be a hard sell, it’s hard to inhale enough. Only crocidolite and erionite have been traced directly to human lung cancer.
To establish liability, one would need to examine possible release scenarios. Usually chrysotile makes it much harder to convince anyone of this type of exposure, because it is hard to see the potential threat. It’s not small enough or durable enough (it is more rapidly broken down in water (days and weeks, as opposed to more than years).
Asbestos with cement is less toxic than say that which comes from brake linings. Brake linings grind and make asbestos have smaller cross sectional area, depositing in deeper lung. Thus, cement companies with the wrong asbestos are relatively hard to pin down and collect on.
I know of two real cases where there was almost no doubt. One was described in the first paragraph and involved chrysotile asbestos. The second one was in Turkey. Only husbands, not wives or children, got mesothelioma. Eech day the males that got this had eaten lunch on a rock next to a cool waterfall pool and went swimming there time permitting. The wives and kids lived some distance away and weren’t exposed. More than half of the men got mesotheliomas and it took a long time to track it down (>5–10 years). It was finally identified as erionite asbestos, an amphibole asbestos, which has quite a small odiameter. It was more durable than grunerite (from Minnesota mines). The exposure was high, over very long time periods.
In my opinion, this chrysotile is an interesting case because the exposure scenario was right and had happened, but with an entirely different asbestos, usually not found in the U.S. Secondly, it was an asbestos containing cement with a complicated composition, less likely to cause mesithelioma. Finally, it was a serpentine asbestos, not an amphibole.
They could probably find out which asbestos, because it usually does not cause mesothelioma and the company knows this. Also, unless one had documentation a high percentage of U.S. asbestos is chrysotile, the most curved and least durable of the asbestos.
The questions asked in this case were relevant to those which would be asked in real life and the scenario is realistic.

This case has students prepare to simulate a hearing on possible treatment of Eric for his ALS using stem cells. Since he is Catholic, there is a religious dimension to consider. It includes good witnesses such as James Thompson, John Gearhart, and Leon Kass. I find it very helpful for non-majors classes in stem cells and human cloning. It isn’t quite up to date, though, having been prepared in 2005.
Suggestions
I have added some characters:
- Shinyu Yamanaka, who in 2007 was able to reprogram skin cells to pluripotency.
- Elizabeth Blackburn, the scientist Bush fired from his ethics committee.
- Jonathan Moreno, Obama’s organizer of his Bioethics Committee.
New References
I like to have the students do this case while they are reading Christopher Scott’s book Stem Cells Now: From the Experiment That Shook the World to the New Politics of Life (Pi Press, 2006) and papers updating it.
I also like to use Potent Biology, the videos produced by HHMI on stem cells, which are available for free from the HHMI web site.
Also the following articles:
- The Yamanaka paper: Takahashi, K., Tanabe, K., Ohnuki, M., Narita, M., Ichisaka, T., Tomoda, K., and Yamanaka, S. 2007. Induction of pluripotent stem cells from adult human fibroblasts by defined factors. Cell 131(5):861–72. doi:10.1016/j.cell.2007.11.019

I teach at a highly selective secondary school. In our ninth grade science course, we are teaching critical thinking skills through the use of medical case studies. While teaching the human physiology systems, we have students work their way through medical cases. In each case the students must take information provided to them and make a reasonable inference (several hypotheses/diagnoses) based on that information. Then they must request further information (lab tests, physical tests, interview questions) and they must give good reasoning for why they are requesting that information. At the end of the case, students must present either in writing or verbally an explanation of their thinking process from start to finish.
Thanks for making these cases available.

This case was a big success in my course "Disease and the Environment." I was searching for a way to engage the students in talking about the choice of research population, formulation of research questions, data gathering and interpretation, presentation of research findings, and the reporting of scientific results in the popular press. All this was to prepare them for their own case studies. The class was also an unusually quiet one, given the subject matter, so I was also trying to liven things up a bit. This case was the perfect vehicle for all of the above.
I followed the questions and teaching notes very carefully. The students were given the case five days in advance of the discussion and they submitted their assigned critiques as scheduled. Then we turned to the question of who wrote the story. Things heated up very quickly and there was a great deal of discussion surrounding each of the suggested questions. I remained the silent recorder of comments most of the time. I found it very useful to list responses on the blackboard so that the class could see the twists and turns that ensued. We arrived at the predicted "wide range of answers to the question about validity" of conclusions. The class agreed that taking a statistics course, as one-third of the group had, would help in this type of analysis. Together they formulated a long list of questions involving confounding variables, researcher bias, and missing information. They agreed that they would like to see the original papers on which the news release was based.
The class lasted a very short 85 minutes. The students were engaged and active the entire time. I agree with the author that this case encourages independent thinking in students and reduces their fear of attacking statistical statements. The group work on this case was both liberating and empowering for the class as a whole.
This is a very well conceived and useful case study. My personal field test was a rousing success. I'll use it again the next time this course is offered and I plan to use it in my introductory statistics class and have passed it on to two colleagues who also teach statistics who are very excited about using a case like this.

I used this case at the end of a semester-long non-majors course on Heredity, Evolution, and Society. We spent about two hours on this case. Students were split into groups of four or five with each group having at least one strong student. I also let each group know that it was important for everybody in the group to understand the problems and answers since I could call on anybody to give the consensus answer.
My students loved this case study since it really helped to tie in concepts that we had gone over all semester and that they had trouble with. In particular, the idea of X-linked versus recessive, writing genotypes, and identifying carriers. This was a great way to have them construct pedigrees and go over the basic concepts of genetics in time for the final.
Thanks for writing this well-designed case.

I modified one of your cases titled, “The Case of the Dividing Cell: Mitosis and Meiosis in the Cellular Court” by Clyde Freeman Herreid and used it while discussing mitosis and meiosis with first year students of medical school. The total number of students was 90. The students found the case interesting and enjoyed the teaching session. At the end of the session, I collected a “feedback proforma,” the results of which I wish to publish in a medical journal along with a discussion of the use of case methods for teaching anatomy. -----------------------------

I used this case as an introduction to mitosis and meiosis. The only alteration I made was to place the names of the characters next to their speaking parts. My students seemed to like it. I had my principal in observing me and he also liked it and thought it was a good intro. I had the jury members act like real jury members and take notes so that if they had to render a decision they had notes to work from.
Over all it was well received and I will use it in the future!

With this case students were grouped and mocked an interdisciplinary team. The team captain and students read the case together. Each team member was given a question to research in order to arrive at a logical conclusion. Students were permitted five weeks to complete the assignment.
Use of the case presented the opportunity to work together as a team and helped develop research skills. Students were able to chart data. Students were also able to assemble mock charts.
We cannot thank you enough for the use of the case studies.

Excellent case study! The dialogue format engages the reader and makes learning more interesting. I followed the notes to the teacher and inserted mini review lessons on the anatomy of the heart and circulatory system, which enhanced the students' understanding of the case. I used unlabelled diagrams, which we labeled together as a class. I involved the students throughout by having them go up to the white board and write definitions/answers to questions. I really liked how it shed light on the differences between men and women with respect to their symptoms of heart disease. -----------------------------

I used the case, "Wake-Up Call," in a class called "Topics in Women’s Health" and it was a real shocker for the students, who all pretty much decided the main character was having panic attacks, an anxiety disorder, or menopause symptoms. Heart "problems" was one of their hypotheses, but not a strong one until near the end. I adapted the case to fit the format I use in class, so I didn’t use it exactly the same way, with the heart as a character. I liked that idea, but it didn’t fit the way we’d been working. It was a terrific case and the students were very challenged and learned a lot. They asked me if this was based on a real person or if it was constructed to make particular points. I didn’t know the answer to that. I found (as I find with any case I use) that I had to make up some family history and life style answers to respond to students’ questions. It’s a little like writing a soap opera, but kind of fun. Thanks to the case authors and the Center for this case, as it formed a big part of my class this spring. -----------------------------

Despite the fact that we are in the UK, the group of ecology students entered into this case study wholeheartedly.
The progressive disclosure of the Historical Updates enabled them to build towards the learning outcomes of their “Understanding Ecology and Conservation” unit.
As our sessions are 90 minutes, we introduced the case study in the latter part of the first session (after a previous topic had been debriefed) and covered the Historical Updates in the whole of session 2, because the groups got VERY involved!

I modified this case slightly for use in my conservation biology class (emphasizing the conservation, downplaying the other issues). I have used it twice, and it was a big hit with the 12-15 students each time. In 2001, it was the very first case I ever used, and I simply asked students to read the case, and decide what they needed to do as conservation professionals (in small groups), including:
- the problem to be solved,
- how to solve it,
- what other information is needed, and
- the approximate cost.

Here in Dutchess County, NY (prime Lyme Disease territory), this provided a very useful and relevant first case in a "Contemporary Issues in Biology" course. I did the case pretty much as offered, with each group presenting the topic as a skit, video, or PowerPoint presentation with accompanying handout and bibliography. It was very well received.
I changed the scenario a bit to get more of a bioethics spin on it: "You are a parent who wishes to send a child to a summer camp. The summer camp requires proof of Lyme immunization. Will you have your child immunized or not?"
After all of the group presentations (each group gave a recommendation), I asked the students to make their decisions and give a reason. We then had an open discussion, after which they are asked to again make a decision and give the reason for it. I then changed the scenario slightly:
- the camp is a music/sports camp and participation almost guarantees the attendees a full scholarship to a prestigious music/sports college program;
- the camp is a computer camp, which will donate $5K worth of computer equipment to the sponsoring school district; or
- you want to get rid of your kid for the summer so you and the spouse can go away and work on saving a failing marriage.
This tests to see how many students change their minds when they see other factors and values coming into play.
Some saw no ethical dilemma here until I explained that I know another public school biology teacher in upstate New York who had her children home-schooled rather than submit them to vaccinations on the basis of problems with animal testing, putting foreign substances into the body, etc. I also referred to a "Law and Order" episode on television where parents are charged with failure to get medical attention for their child on religious grounds. It didn't specifically relate to vaccinations, but the principle is the same. Upon hearing these, the students saw how some people could have an ethical problem with this.

I thought this lab was a great way to introduce the concepts and application in a realistic context. I used it as written and students responded to it very well. They enjoyed the analysis and discussion but felt that they would have liked more time (our class periods are 55 minutes). I too felt like we could have used more time—there is no reason we can’t discuss this further next class. I also think with more experience I will get better at facilitating the discussion. -----------------------------

I used this case in a non-majors class on Microbiology and Infectious Diseases. We went over this case a week after they had covered antibiotics and antibiotic resistance. One of the things that puzzled my students was the fact that Kayla died in spite of the fact that the S. aureus that caused her infection was susceptible to vancomycin. In fact, at the end of the case, Collins’ friend, Kurt, suggests a combination treatment of vancomycin/cefazolin, although he cautions her about the possibility of vancomycin-resistance. I would love to get some feedback/clarification/thoughts on this.
Overall, my students love the case studies since they help to tie things together and help them see the relevance of the material presented in lectures. Thanks very much.

I used this case in an introductory microbiology class consisting primarily of medical assistants in July of 2004. This actually brought together many of the concepts we had discussed. Overall the students really enjoyed this case; however, they were upset when they discovered the patient died. They also wanted some information as to how her hip joint became infected — was it due to an injury to the joint or another infection somewhere else?
I presented this case over a period of four class periods and they seemed to like that. I enjoyed using it and will probably use it again as a project the next time I teach this class.
I may also use this as a basis for homework — such as doing a one-page paper on the different antibiotics mentioned or for further research by the student on MRSA.

It was my intention to give my students the opportunity to experience "real-time" issues in environmental science. This case study piqued their interest to the point that they actually wanted to "act out" each person’s position in the case, including the narrator’s part.
I plan to have my students present this case as a short "play" to be performed at our neighboring campus middle school. Prior to the performance, the narrators will explain the profiles for each member in the play. At the conclusion, other students will form stations within the classroom and ask the middle school audience the questions that are included in the case study. The purpose of this is to develop a discussion session rather than just an informal assessment. This is planned as a culminating activity after my students have completed their discussions on the case. They all need to be well versed on the issue so they can monitor and adjust at their individual middle school discussion stations.

The "story" of the case-study was given to the students as part of their last semester exam in a Human Physiology course often taken by our pre-med/vet/dental school students. Students had been told that there would be one question that would integrate concepts over the entire semester (this was greeted with moans and groans). Of the numerous questions that Dr. Strong had listed with the case study, I used seven for the exam. Each question was worth between 1 and 4 points, depending on difficulty and length of answer expected.
Student responses were mixed. I had two Varsity rowers in the class of 35, and also Varsity swimmers. The athletes and their close friends were enthusiastic about the question (very relevant to their lives). Those students who like to memorize instead of learn and apply material were not happy with the question. The entire exam was 1 1/2 hours and included 35 other short answer/matching/multiple choice questions.
Since I return exams to students, future semesters of Human Physiology will have had access to the exam and will have had access to this case study. Next year I plan on using this as a "review" question in the form of a group project. I have not yet decided how to exactly assign this, but will involve setting aside a day of lecture for students to present their answers to two to three of the questions/group. The remainder of the class is expected to agree/disagree with a group. I may ask one group to answer one question completely incorrectly to "test" the remainder of the class to make sure that they are awake/paying attention.

First, I want to thank you all tremendously for the use of this excellent site and material. I have no doubt that this is one of the best ways for students to learn to actually understand and remember the material and be able to apply it to real life situations.
Regarding this case — mine is a high school anatomy class consisting of 11th & 12th grade students. They were excited to receive the case and related to the individual in the case and his circumstance. As we started they were full of ideas. As they completed each part I questioned the group members and asked for explanations/clarifications, etc., before they received the next part. The students started to get frustrated at the process when they weren’t "told" the answers and needed to do more research. But then they were quite proud when they finally got the answers and could explain why. So, in all, they seemed to go through the cycle of excitement, frustration, excitement, frustration, excitement.... Sort of like real life.
They did have particular problems with the CT scan. This wasn’t because they had never read one - they actually did a very nice job figuring that part out. (In fact, I gave most of them the CT scan before the blood work so they weren’t quite as sure of the answer yet.) Their difficulty rather resulted from the fact that the upper GI image seems to be flipped backwards from the Chest image. In other words, the right and left side of the body are reversed in the images.
Outside of patient history I’m not sure there is any reasonable way for them to know it is the patient’s “left” lung. And even with the patient history it could actually be that he damaged his "right" lung when he was smashed against the boards even though he was hit with the stick on his left side. So, as a suggestion, I would like to see that image flipped. I also believe, although I am not certain, that these CT scan images are typically viewed as if you are looking up from the patients feet, thus putting the patient’s left on the viewing right. If that is in fact the case both images should reflect that. [Editor’s Note: The relevant portion of the case has been revised as a result of this comment.]
As a fun follow-up activity I had the students write an “Ode to Rick” where they wrote a poem summarizing the story, the test results and their meaning, the treatment and prognosis. They really enjoyed it and it helped me see what they understood and still needed some help with. If you would like to see these "poems" for a little chuckle they can be found on my website at http://www.docfleetwood.net/anatomy/odetorick.htm
Again, this case was done beautifully and I highly appreciate the time and effort put into it.

The students enjoyed this case. I think it was well done, and it is a fun way to learn.
I made only minimal modifications:
- I asked my students to read relevant passages from their textbook (Kuby’s Immunology) rather than consulting the online resources.
- I used the info you provided online to create a PowerPoint presentation, and I added a few images that I got from a Google image search for a normal baby boy, a child getting an ear exam, a photo of David Vettle, etc.
- I have a small class, so we worked on the case as a whole, and the class split into smaller groups just to read and study the possible causes of SCID.

On two occasions I have used this case within the first class of a large introductory biology course for non-majors. I use a somewhat abbreviated version (I project the narrative and questions from Part I, then II, and then III), and it takes about 25 minutes to complete. As intended, the case serves as an introduction to the scientific process, as well as one of the first group activities that students do. It is very effective. Turning students loose in small groups (consisting of their immediate neighbors) on the study questions of Part I results in instantaneous “buzz,” and the hypotheses generated are typically thoughtful and reasonable. I suspect my enthusiasm for this case is shared by many others—kudos to the author. -----------------------------

I used this case study the first day of class for my sections of non-science majors (20 students per section). The case study was very popular and the students enjoyed being "detectives" along with Semmelweis. It was a great way to introduce the scientific method. The study generated a lively discussion and great student participation. It also set the tone for the semester: encouraging class participation, fostering critical thinking, and promoting group discussion. The level of the material was appropriate for an introductory course. The case study/discussion proceeded very smoothly. The time estimates in the teaching notes were accurate.
In each of my classes, one or two students immediately suggested that washing hands might be important or that germs were being spread. This can be handled by asking what evidence makes that seem important (early in the case study there is none), or by pointing out that Semmelweis and the other doctors did not know about germs.

The case was used in a small class of second semester chemistry for non-majors. Polymer chemistry was covered briefly before the assignment.
The student references were handed out in class. The class was split into groups of four with one group of five. Each person was assigned to a role: mother, consumer reports scientist, plastics industry rep., judge (moderator for the discussion), and in the group of five an outside scientist. Each student was to read the references and think about points which they would like to ask the other experts (in the form of five questions). In addition they were to prepare answers from their assigned perspective which they felt might be addressed. The judge was given the task of coming up with the method to present the case with the group.
On the next class period, the groups discussed the case. Occasionally, groups needed assistance in discovering what might be valid arguments in the consumer report. Once the discussions died down I presented highlights of the main points that one might want to consider. Then a vote was cast about who would use polycarbonate bottles. Surprisingly, only a small portion of the students would continue using the bottles even though they believed that the consumer report case was not supported by facts. The students then received a copy of the summary of the RTI report given in 2001 confirming the safety of polycarbonate bottles.
The case was well received and very engaging.

I plan to use this case study with my first-year high school students during their polymer unit. Not only will it be a great timely connection but it also involves another important concept in my course - levels of detection and risk factors. I read about your site in C&E News. What wonderful resources. I will share the knowledge of this site and this particular case study with my high school colleagues at our first educators' discussion group of my local ACS. My polymer unit looks at some physical/chemical properties which distinguish the six major plastics. I then have the students study modifications to the slime recipe to produce products of greater viscosity or bouncibility. They design their own testing methods and measurement protocols. We will then end with this case study. This part of the course happens during the second quarter. -----------------------------

I’m a sales manager for (among other glass products) baby bottles made of special glass (borosilicate glass with expansion factor 3.3). Although many Americans may not be aware of this, such bottles have been in use for generations (since the 1920s), especially in Germany. The company I work for still produces such bottles, as do certain other factories in France, the Czech Republic, Italy, China, etc. In fact, consumption of these bottles is still in the double digit range of millions. In my opinion, bottles made out of borosilicate glass are preferable to those made out of ordinary soda lime glass due to the bad thermal shock resistance of the latter which does not allow for optimal hygenic cleaning.
The case study highlights six points which, to my understanding, are related to chemistry. But the "development of critical thinking skills..." should also address political, commercial and general environmental aspects, too. Historically, these factors frequently have triggered more profound research. After Our Stolen Future was translated into Japanese, health authorities in Japan stopped use of PC (polycarbonate) dishes in schools. The baby bottle market in Japan, which formerly manufactured according to the ratio of 25% glass - 75% plastic, subsequently changed to 80% glass - 20% plastic. In Europe, however, the effect has not been the same; here the market is still 25% glass - 75% plastic.
Basic worries, as well as proved and unproved statements, are often juxtaposed with the power and persuasion of industry representatives. Such basic worries apparently linger even after evidence is examined, as witnessed by the final vote of students at the end of the case (see Comment 1: "Surprisingly, only a small portion of the students would continue using the bottles even though they believed that the consumer report case was not supported by facts").
The American Plastics Council, although encouraging inquiries into "the truth," continues to defend the image of the plastic industry. However, this is not an area for blind trust since there is a long list of industry "trust me’s" that have been heard before: nuclear power, agent orange, car exhaust, tobacco smoke.... In the end, who evaluates (and who should evaluate) what is most important for a given population? Administrators representing the public health? Members of the relevant business community? I think that the case discussion should be broadened to include such a range of issues, on both the "pro" and "con” sides" when analyzing health issues.

I am not a teacher, but rather a research analyst at Friends of the Earth. I recently presented Saxena and Stotzky's paper at a National Academy of Sciences forum on potential unintended health effects of genetically engineered foods. I have a few comments on points you raised.
First, I find it interesting that hybrids derived from two distinct transformation events (MON810 and Bt11) exhibit the same unintended effect—increased lignin levels. These plants were both transformed by gene gun, maximizing variability in chromosomal insert location. One would think different insertion sites would yield different unintended effects (if the inserted promoter is somehow driving the increase in lignin, that is). I suppose Cry1Ab protein could disrupt cellular metabolism somehow, producing the same effect in MON810 and Bt11. This would require looking closely at the lignin biosynthetic pathway, which involves shikimic acid, an intermediate in the synthesis of aromatic amino acids. This seems unlikely, though.
An interesting observation, perhaps unrelated, is that I have seen reports that Roundup Ready soybeans have increased lignin levels in some circumstances, and reduced levels of aromatic amino acids in others. Could a non-specific effect of the engineering process be at play? The problem here is that RR soybeans, I believe, are transformed via Agrobacterium.
I find your mechanical explanation unconvincing. I don't think the paper says anything about corn borer infestation or damage; therefore why would the Bt varieties grow larger, especially when grown indoors where presumably there are no pests?
I would be interested to hear your comments. I spoke with Stotzky, and he didn't have answers to the questions raised above.

Case Author's Reply:
Thank you for your interesting comments on the Saxena and Stotzky paper. I agree that it is interesting that two of the three hybrid transformations do indeed seem to increase lignin concentration. The evidence for the third transformation is incomplete, and it is interesting that the "Maximizer" hybrid with Bt actually has lignin levels comparable to the non-Bt hybrids. I also think you are right that a strictly mechanical explanation is unlikely, particularly since the growth room levels also were increased. Clearly there is a genetic component to lignin production, which was increased by the Bt transformation. Equally clear is that there is an environmental component, as indicated by the lower lignin levels in the growth room (where plants probably received less mechanical stress / damage).
My main point in writing the Saxena and Stotzky case was not to examine Bt or lignin per se, but rather to examine an interesting recent paper with a flawed experimental design and a weak statistical analysis. The authors probably overstate their results, given the very small sample sizes and limited samples (only from one node, only from one date). Their use of t-tests is probably inappropriate, and in particular enables them to completely overlook potential interactions between site and transformation. They also have no statistical analysis of different transformations overall, which could have been done. Finally, their use of SEM as a measure of variability, particularly given that they did not report sample sizes, is in my opinion a mistake, because SEM is so highly dependent on sample size and carries little or no intrinsic information about variability around a mean.
By the way, my stats class just did this case last week. My students were particularly interested in how this paper really does have some interesting stuff, but the potential punch is reduced by the mistakes. We ended up concluding that part of the blame should be placed on the reviewers' shoulders.

I used this case study for an introductory, non-lab biology course called Human Biology. Needless to say, my students are typical "science-phobes" and generally have a minimal background in biology. I used this case after completing the respiratory and circulatory systems. They did not understand all of the terminology that was used; however, they did their best using what they did know to apply their knowledge to a real-life situation. I feel that this helps them to prepare for my tests because I use a great deal of critical thinking type questions. They find these challenging, but it is great exercise and it also makes for a much more alert class! -----------------------------

This is a question, not a comment, and would influence the answer to CQ6; I just want to be sure I get things right. I will be using this case in about 10 days on a class for non-science students. I just wondered if I missed something about the H1N1 so-called swine flu. Is there any evidence at all that it came from pigs? As I understand, it contains RNA segments from avian, porcine and human sources, and I have never seen anything about it being transmitted directly from pigs to humans although apparently a Canadian pig got it from a human. There was a big pig facility in the Mexican town where the first cases were found, but I have seen nothing about those pigs clearly transmitting it to humans. I used to do surveillance of avian flu viruses in Hong Kong before anyone was interested (the 80s)and we thought that the next pandemic would originate where pigs and ducks lived together on farms in SE Asia, but it didn’t happen (at least not yet). -----------------------------

We used the case as an example of the scientific process with our freshmen Middle Years Programme International Baccalaureate (MYP/IB) biology students. It worked very well and the students enjoyed the step-by-step process. We used sections A, B, C. We also showed a DNA video that had a discussion of sickle cell disease. It was very effective. The case provides an excellent transition from the study of DNA and biotechnology to the study of genetics. -----------------------------

As a former high school environmental science teacher and college professor (biochemist), I found your case history very relevant to the dangers of mercury pollution. There is a very urgent need to get this information into the hands of the next generation of citizens.
You might include the politics and economics of controlling mercury pollution as another component to your case history. It could be used as an extra credit project to further understand how science and politics interact with each other in the real world.
Additional information you might find useful:
- The CDC has estimated that as many as 600,000 newborns are at risk from methyl mercury from the fish consumed.
- The California gold rush over one hundred years ago used mercury to mine for gold and today mercury is still contaminating rivers and lakes in those mining areas.
- The ongoing National Health and Nutrition Examination Survey indicate that people living in coastal areas have higher levels of mercury in their blood than individuals living elsewhere.
- Check out the www.cleanair.org, www.GotMercury.org, www.who.int/ceh, and www.zeromercury.org as well as Dr. Hightower's book "Diagnosis: Mercury, Money, Politics & Poison" (2009).
I hope you will find these comments useful.

My students LOVE this case study! I like the original animation for how the MDMA works, but this one is put together pretty well. I find that my students may not get all of the vocabulary, but whenever I reference this case study they can figure out what I am talking about and relate back to cell transport and how it works. FYI, I teach this to my regular biology students, so the relevance this has to them is high and makes talking about the cell much more interesting and real to them. -----------------------------

The case works well with students who have access to the Internet outside of class. I adapted the study by working with the students in the computer lab while reviewing the video clips from PBS. You may want to check out the New York City Department of Health and Mental Hygiene. This site allows access to three datasets which can be searched by several variables, specifically with tuberculosis. This will allow students to check out the rates of tuberculosis by borough, SES, gender, etc. The website is: https://a816-health3ssl.nyc.gov/ -----------------------------

The PO2 would be below normal initially as less O2 is carried by the hemoglobin (as indicated in the case). The peripheral chemoreceptors detect variation in O2 concentration in arterial blood. Presumably they send a signal to the brainstem that is translated to increased ventilation rate. This can result in the O2 level increasing to normal or near to normal level. However, the SPO2 level does not increase (as there is not sufficient Hb) until after the patient is treated with methylene blue.

A good case. I like the structure. It is ahistorical, (and not a little disrespectful) for the narrator to refer to Dr. Franklin as “Rosy.” This was not a nickname that she accepted—it was thrust on her by Watson in his own published version of the events in The Double Helix. -----------------------------

Viruses regularly create new combinations of their DNA, exchanging pieces of DNA with other viruses. The swine flu is actually a strain of influenza with genes from flu that infected pigs, flu that infected birds, and flu that infected people. So the name is not due to the source of infection, but to the fact that this is a new type of flu that we are not able to respond well immunologically to because we have not previously encountered the swine component of this flu’s genetics.
It sounds like the questioner already understands this, and is wondering how this flu moved into people. And that piece we don’t know. We do know that there is the pig flu, which doesn’t (normally) infect humans, and the human flu (which we have been able to resist enough that it can't develop an epidemic outbreak). Presumably an animal (either pig or human) was infected by both versions of the influenza, and while infected the two strains swapped DNA. So the virus we call H1N1 has the genes to invade human cells and manage human-to-human transmission, and also has genes from the pig variety that we don't have defenses against. Researchers have been hunting through Veracruz trying to find this answer. See http://www.cnn.com/2009/HEALTH/05/06/swine.flu.origins/index.html.

Eric’s comments are on-target. Conclusively documenting viral transmission on a specific case basis can be exceedingly difficult. The links below provide the experts’ views on the subject.

1. Regarding the use of CA-125, it should be strongly emphasized that this “marker” measures inflammation, not cancer per se. There is no specific blood test for ovarian cancer like the PSA test for prostate cancer. This is important because students need to understand that many lives could be saved (perhaps 15,000/year) if there were a way to screen women for ovarian cancer. This would mean diagnosis at stages I or II when the cure rates are much higher than for stages III or IV when cure rates are dismal. Students could be asked to look up survival for these stages.
Students should be asked to explain why we don’t have a specific test. Are there biological reasons? There are also political/economic questions that students should consider since they may well affect their lives. What issues are involved with insurance companies having to pay for screening mammograms? What is the reason for the new idea that the PSA need not be done on men over the age of 70? Why is the CA-125 not used for screening, even if there are some false positives?
2. Why do we use the term "remission"? Who invented that word? Was it oncologists? Certainly they use it and so does every one else! What does it mean? To me it means that there’s no sign of that cancer, BUT we’re waiting for it to return, for the other shoe to drop, so to speak. If a person has a heart attack or a stroke, and they’ve recovered, there’s a reasonable probability of a repeat. Have students look these numbers up. BUT we don’t say that these patients are "in remission."
How does the term "remission" affect the patient? Does it instill a bit of unnecessary fear? (The doctor must think it’s coming back!) Does this term remove hope that the patient might be cured?

Your cases are excellent in their depth and teaching quality. I had the good fortune to meet both Drs. Pauling and Castle. They did indeed have the famous conversation while traveling by train from a meeting. The other interesting historical item I recently learned came from Vernon Ingram. He did not come to the MRC with the intent of working on sickle hemoglobin. Another researcher had failed in some crystallography work on sickle hemoglobin because of the low resolution at the time. Ingram helped Max Perutz with putting mercury residues on hemoglobin A to improve the crystallographic resolution. Francis Crick then suggested that he look into the question of the difference between normal and sickle hemoglobin, since there was a left-over sample from the failed experiment. Science proceeds in the strangest ways! -----------------------------

This is awesome and timely! I’m doing human evolution in my general biology class this week and I’ve been looking for just such a case. I have one concern that I would like to past back to the authors.
I know that there are disagreements among paleoanthropologists, but I’m finding that most of my sources include Pan (chimps) in the Hominini Tribe. This case appears to exclude chimps from the Hominini (commonly referred to as Hominins).

Thanks for your comments on our case.
There is still a dispute among paleoanthropologists about the use of the term hominin. The term is used for the taxonomic level of tribe and the dispute addresses how closely related chimps and humans are. The most common usage is that used in our case, based on the assumption that chimp and human lineages are different tribes and using hominin for the human lineage. There are two competing usages. The one you use assumes that chimp and human lineages belong to one tribe, the hominin. Finally, a third group of paleoanthropologists argues strongly that chimps and humans belong to the same genus and refers to chimps as Homo troglodytes. We have added a note about this controversy to the case teaching notes.

The case was very well-received. Students appreciated being able to learn more about what is and isn’t science by working with a concrete example. I modified the flow chart that helps students distinguish science vs. pseudoscience, junk science and antiscience (e.g., it seemed that “anecdote” should not be listed as part of the methods of science).

Comment and Author's Response
In principle, this case looks like a good way to talk about cell structure in an introductory course. However, I was VERY disappointed by this case, for several reasons:
(1) In this case, the researchers examine a blood sample microscopically and identify Gram-negative bacteria by their size, presence of DNA and outer membranes! It’s not made clear until later that they used an electron microscope, which is likely to lead to the misconception that a light microscope could be used to perform this analysis. More importantly, it leads to the misconception that electron microscopy would be used to identify an infectious agent. Instead, why not teach methods of identifying prokaryotic and eukaryotic pathogens that might actually be used, such as Gram staining to identify a Gram-negative pathogen?
Author’s Reply: The gram staining method is briefly mentioned in the case as well as in the case teaching notes. In the interest of keeping the slides to a minimum of text and the length to 75 minutes, details about the gram stain as well as microscopy were not written out in detail, but faculty can easily elaborate at length if they so desire.
(2) Why would the researchers look at a blood sample? If this individual has bacteria in her blood, she’s septicemic and will be dead long before the electron microscopy is done. The idea that blood remains sterile except in an extremely serious and widespread infection is valuable for students to learn—instead, this case will again create mis-perceptions. Why not talk about taking appropriate samples for the symptoms and organism under consideration?
Author’s Reply: This case is not designed to cover details of microbiology sampling and is designed for introductory biology courses which never have details on sampling techniques in the textbook. This would make an excellent extension of the case in a microbiology course, though.
(3) The DNA analysis component is clearly intended to teach the importance of molecular genetics in identifying species today, but it’s unrealistic in terms of how molecular analysis might be used. PCR would be much more realistic here! Antibody-based tests could also be mentioned.
Author’s Reply:< Again, students at this stage of an introductory biology case have not learned about PCR or antibody tests, so it would be unnecessarily confusing to mention them here.
(4) The case has one of the students’ mothers sending all manner of antibiotics, antivirals and other chemotherapeutics, which the students administer rather indiscriminately based on the results of their analysis, and also take prophylactically. Obviously, this aspect of the case is meant to be somewhat facetious, but rather than seizing an opportunity to educate about proper use of antibiotics, it does the opposite.
Author’s Reply: Absolutely, and the case specifically highlights how useless it was to use antibiotics without knowing what the disease organism is. The more serious issues of antibiotic resistance would make an excellent follow-up discussion in later lectures in the course.
Rather than showing how biological knowledge might be used in an actual case, this study exaggerates the case so much that is seems entirely artificial. Further, it may create more misconceptions than it cures. This case does not seem to be of the quality typical of NCCSTS. I suggest it be greatly revised or removed from the site.

Comment
I anxiously opened this case expecting to find how the amount of caffeine and other ingredients affect one’s health. But, I only found a discussion on sugar. I looked up the Wikipedia article on one of the drinks, Red Bull, and found that the high content of caffeine in it acts on the inner surface of blood vessels, the endothelial lining, and also interferes with normal blood coagulation. Small amounts of cocaine have been found in it. These seem more significant than calories. The caffeine makes you feel energized and more awake and the cocaine, if enough to have an effect, may reduce normal pain sensations. So, how about revising this case to show the potential detrimental effects of the ingredients other than sugars. I noticed in the Wikipedia article the recommendations for athletes to keep hydration and such power drinks are not recommended.
Authors’ Reply
The purpose of the case is really to get students to realize the difference between what serves as energy-producing compounds and what are stimulants. The role of trace amounts of cocaine is not within the scope of this case study.

The NASA link was blocked. I had students review the links in advance as research without really knowing what the content of the case was going to be.
We also spent quite a bit of time talking about crashed and elevated glucose levels and how that presents, since some of the symptoms mirrored those of either high or low glucose levels, including diabetic shock.
