Trismus as a Presenting Symptom in a Case of Progressive Encephalopathy with Rigidity and Myoclonus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In this report we present a clinical case of trismus. The patient in question showed symptoms of trismus for 3 days, rapidly leading to respiratory insufficiency. Afterwards she developed myoclonus and progressive encephalopathy. Neurological workup showed no relevant abnormalities. A CT of the abdomen revealed a mass in the lower abdomen, which turned out to be an ovarian teratoma. Progressive encephalopathy with rigidity and myoclonus (PERM) was diagnosed clinically. Treatment with corticosteroids, benzodiazepines, and levetiracetam did not ameliorate the patient's condition. Only after the introduction of plasmapheresis was there a spectacular improvement in her clinical state. In this case we could not detect associated antibodies. The most likely cause of PERM is paraneoplastic disease secondary to ovarian teratoma. This type of tumor has been associated with multiple paraneoplastic neurological conditions, but this is the first case associated with PERM. To date there is only one publication on trismus as a sole presenting sign, with a quite similar disease course.
