Abstract

Introduction Thyroxine supplementation of patients with hypothyroidism is usually simple. A few patients, however, continue to present elevated TSH levels despite large doses of L-thyroxine.Case We report the case of a 71-year-old women who had had a thyroidectomy 10 years earlier and had since been hospitalized repeatedly for profound hypothyroidism. Despite her consistent claims of good adherence to her treatment regimen, we considered the diagnosis of L-thyroxine pseudomalabsorption and confirmed it by thyroid hormone absorption tests.Discussion L-thyroxine pseudomalabsorption due to concealed poor treatment adherence should be considered after ruling out drug or dietary interference and true organic malabsorption. Diagnosis of this factitious disease can be confirmed by L-thyroxine absorption tests.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A completely normal result in the LT4 absorption test in individuals suspected of having malabsorption is strongly suggestive of pseudomalabsorption.

    “A completely normal result in the LT4 absorption test in individuals suspected of having malabsorption is strongly suggestive of pseudomalabsorption (130).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
