This case report aims to describe the effects of craniosacral therapy and acupuncture in a patient with chronic migraine.
A 33-year-old man with chronic migraine was treated with 20 sessions of craniosacral therapy and acupuncture for 8 weeks. The number of migraine and headache days were monitored every month. The pain intensity of headache was measured on the visual analog scale (VAS). Korean Headache Impact Test-6 (HIT-6) and Migraine Specific Quality of Life (MSQoL) were also used.
The number of headache days per month reduced from 28 to 7 after 8 weeks of treatment and to 3 after 3 months of treatment. The pain intensity of headache based on VAS reduced from 7.5 to 3 after 8 weeks and further to < 1 after 3 months of treatment. Furthermore, the patient’s HIT-6 and MSQoL scores improved during the treatment period, which was maintained or further improved at the 3 month follow-up. No side effects were observed during or after the treatment.
The authors concluded that this case indicates that craniosacral therapy and acupuncture could be effective treatments for chronic
migraine. Further studies are required to validate the efficacy of craniosacral therapy for chronic migraine.
So, was the treatment period 8 weeks long or was it 3 months?
No, I am not discussing this article merely for making a fairly petty point. The reason I mention it is diffteren. I think it is time to discuss the relevance of case reports.
What is the purpose of a case report in medicine/healthcare. Here is the abstract of an article entitled “The Importance of Writing and Publishing Case Reports During Medical Training“:
Case reports are valuable resources of unusual information that may lead to new research and advances in clinical practice. Many journals and medical databases recognize the time-honored importance of case reports as a valuable source of new ideas and information in clinical medicine. There are published editorials available on the continued importance of open-access case reports in our modern information-flowing world. Writing case reports is an academic duty with an artistic element.
An article in the BMJ is, I think, more informative:
It is common practice in medicine that when we come across an interesting case with an unusual presentation or a surprise twist, we must tell the rest of the medical world. This is how we continue our lifelong learning and aid faster diagnosis and treatment for patients.
It usually falls to the junior to write up the case, so here are a few simple tips to get you started.
Begin by sitting down with your medical team to discuss the interesting aspects of the case and the learning points to highlight. Ideally, a registrar or middle grade will mentor you and give you guidance. Another junior doctor or medical student may also be keen to be involved. Allocate jobs to split the workload, set a deadline and work timeframe, and discuss the order in which the authors will be listed. All listed authors should contribute substantially, with the person doing most of the work put first and the guarantor (usually the most senior team member) at the end.
Gain permission and written consent to write up the case from the patient or parents, if your patient is a child, and keep a copy because you will need it later for submission to journals.
Gather all the information from the medical notes and the hospital’s electronic systems, including copies of blood results and imaging, as medical notes often disappear when the patient is discharged and are notoriously difficult to find again. Remember to anonymise the data according to your local hospital policy.
Write up the case emphasising the interesting points of the presentation, investigations leading to diagnosis, and management of the disease/pathology. Get input on the case from all members of the team, highlighting their involvement. Also include the prognosis of the patient, if known, as the reader will want to know the outcome.
Coming up with a title
Discuss a title with your supervisor and other members of the team, as this provides the focus for your article. The title should be concise and interesting but should also enable people to find it in medical literature search engines. Also think about how you will present your case study—for example, a poster presentation or scientific paper—and consider potential journals or conferences, as you may need to write in a particular style or format.
Research the disease/pathology that is the focus of your article and write a background paragraph or two, highlighting the relevance of your case report in relation to this. If you are struggling, seek the opinion of a specialist who may know of relevant articles or texts. Another good resource is your hospital library, where staff are often more than happy to help with literature searches.
How your case is different
Move on to explore how the case presented differently to the admitting team. Alternatively, if your report is focused on management, explore the difficulties the team came across and alternative options for treatment.
Finish by explaining why your case report adds to the medical literature and highlight any learning points.
Writing an abstract
The abstract should be no longer than 100-200 words and should highlight all your key points concisely. This can be harder than writing the full article and needs special care as it will be used to judge whether your case is accepted for presentation or publication.
Discuss with your supervisor or team about options for presenting or publishing your case report. At the very least, you should present your article locally within a departmental or team meeting or at a hospital grand round. Well done!
Both papers agree that case reports can be important. They may provide valuable resources of unusual information that may lead to new research and advances in clinical practice and should offer an interesting case with an unusual presentation or a surprise twist.
But perhaps it is more constructive to consider what a case report cannot do.
It cannot provide evidence about the effectiveness of a therapy. To publish something like:
- I had a patient with the common condition xy;
- I treated her with therapy yz;
- this was followed by patient feeling better;
is totally bonkers – even more so if the outcome was subjective and the therapy consisted of more than one intervention, as in the article above. We have no means of telling whether it was treatment A, or treatment B, or a placebo effect, or the regression towards the mean, or the natural history of the condition that caused the outcome. The authors might just as well just have reported:
WE RECENTLY TREATED A PATIENT WHO GOT BETTER
Sadly – and this is the reason why I spend some time on this subject – this sort of thing happens very often in the realm of SCAM.
Case reports are particularly valuable if they enable and stimulate others to do more research on a defined and under-researched issue (e.g. an adverse effect of a therapy). Case reports like the one above do not do this. They are a waste of space and tend to be abused as some sort of indication that the treatments in question might be valuable.
