Primary hypothyroidism resolves after switching from L-thyroxine solid tablets to liquid oral substitution. A rare case without evidence of an underlying gastrointestinal malabsorption syndrome.

A case of refractory primary hypothyroidism is presented. Despite laboratory-guided hormonal substitution, the patient remained hypothyroid. Multiple diagnostic tests ruled out all known causes of levothyroxine malabsorption.

The diagnostic challenge of abdominal tuberculosis in nonendemic countries: A case series from a tertiary hospital in Germany.

Abdominal tuberculosis is a rare clinical condition in nonendemic countries and should be included as differential diagnosis by unspecific abdominal complaints, especially in patients with immigration background from high-prevalence regions.

Successful Treatment of an Immune-Mediated Colitis Induced by Checkpoint Inhibitor Therapy in a Patient with Advanced Melanoma.

Immune checkpoint inhibitors (ICIs) have been used as immunotherapeutic agents in several malignancies because of their ability to modify the T cell-mediated response against tumor cells. Dual checkpoint inhibition improves remission rates in patients with metastatic melanoma compared to monotherapy. However, a higher incidence of toxicity, including immune-related colitis, has been reported before.

Autoimmune hypophysitis secondary to therapy with immune checkpoint inhibitors: Four cases describing the clinical heterogeneity of central endocrine dysfunction.

Introduction: Immune checkpoint inhibitors are becoming increasingly important in oncology. Immune-related adverse events, including autoimmune hypophysitis, have been reported before.

Case Report: We present a case series of three males and one female, suffering from either malignant melanoma or renal cell carcinoma, who developed hypophysitis under Nivolumab and/or Ipilimumab.
