Thyrotoxic Periodic Paralysis With Features of Andersen-Tawil Syndrome: A Case Report and Literature Review.

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
Thyrotoxic periodic paralysis (TPP) is a rare manifestation of hyperthyroidism. The pathophysiology of hyperthyroidism causing periodic paralysis involves the Na+/K+ ATPase and potassium channels. We present a case of a 30-year-old male who presented to the ED with acute onset of upper and lower limb weakness. The patient was found to have bilateral weakness in the upper and lower limbs, orbital hypertelorism, and mandibular hypoplasia. He was also found to have hypokalemia, low thyroid-stimulating hormone (TSH), elevated thyroid peroxidase antibody, and elevated thyroid-stimulating immunoglobulins. The patient's EKG was remarkable for a prolonged QTc interval. The patient regained his muscle strength after potassium replacement in less than 24 hours. He was started on methimazole and potassium supplements. Our case is unique because it shows the possibility of the presence of Andersen-Tawil syndrome (ATS) (long QT syndrome 7), diagnosed by the presence of periodic paralysis, long QT, and dysmorphic facial features with TPP. In conclusion, thyrotoxicosis can trigger ATS; also the two syndromes can co-exist owing to the similarity in their pathophysiology.
