Review Case Reports
Hungry Bone Syndrome Secondary to Subtotal Thyroidectomy in a Patient with Thyrotoxicosis.
Patients with thyrotoxicosis are prone to transient hypocalcemia after thyroidectomy, which may be due in part to surgical damage to the parathyroid glands. Hungry bone syndrome (HBS) can also cause hypocalcemia after thyroidectomy. HBS is due to increased osteoblast-mediated bone formation activity and normal or decreased bone resorption activity. ⋯ After two months of treatment, she no longer had spasms and her paresthesia improved. Meanwhile, serum electrolytes and parathyroid hormone levels had almost returned to the normal ranges. This is a rare case of HBS presented as a complication of subtotal thyroidectomy in a patient with thyrotoxicosis.

Review Case Reports
A Case Report on Type 2 Amiodarone Induced Thyrotoxicosis and Hypercalcemia.
Amiodarone, the most commonly used antiarrhythmic drug, can cause either hypothyroidism by inhibiting iodide transport into the thyroid gland or hyperthyroidism. We present a rare case of type 2 amiodarone-induced thyrotoxicosis with hypercalcemia. A 64-year-old man with systolic heart failure, hypertension, and hyperthyroidism presented with complaints of dyspnea on exertion, orthopnea, and vomiting for several days. ⋯ Hypercalcemia, a rare presentation of AIT, was treated with calcitonin and intravenous fluids. The patient was taken off methimazole and started on propylthiouracil for the persistent elevation of thyroid hormones, especially FT3, and to reduce the conversion of T4 to T3. The patient was not completely responding to treatment with propylthiouracil alone, so prednisone was added to the regimen on day 12, effectively returning the patient to the euthyroid state.

The gastrointestinal (GI) system, is most vulnerable to hypoperfusion among the splanchnic organs. Disturbed perfusion of the mesenteric area may lead to GI dysfunction, cause further injury to the patients and even vital outcomes. However, due to the limitation of detection methods, the hemodynamic influences on mesenteric blood flow in clinical practice are not fully understood. ⋯ Based on the best current evidence from these sources, we described the major influences on mesenteric blood flow in the context of physiologic accommodation, disease-related effects and the consequences of medical interventions related to shock conditions. During circulatory shock, sepsis, and medical interventions related to shock treatment, mesenteric blood flow changes and shows different features. We need to carefully consider these issues when making medical decisions, and more work needs to be done on early detection of GI hypoperfusion and its accurate correlation with GI dysfunction.

Prostate transmembrane protein androgen-induced 1 (PMEPA1) is reportedly highly expressed in pancreatic cancer (PC). However, its biological role and associated mechanisms have not been addressed in PC progression. ⋯ PMEPA1 promotes the progression of PC at least partially by activating the MAPK signaling pathway; thus, the PMEPA1/MAPK axis may be a potential therapeutic target in pancreatic cancer.
