Severe hypoglycemia occurs with different types of tumors, including islet cell and non-islet cell tumors. Non-islet cell tumor hypoglycemia (NICTH) is a rare and potentially life-threatening complication of malignancy. The primary underlying mechanism of NICTH proposed in the literature includes paraneoplastic overproduction of insulin-like growth factor-2 (IGF-2), the production of autoantibodies against insulin or its receptors, or the presence of extensive metastatic burden replacing hepatic tissue or adrenal glands.

For example, a paraneoplastic syndrome can be triggered by an underlying malignancy or vice versa, where chronic inflammation of organs affected by autoimmunity can induce malignant transformation such as the case with inflammatory bowel disease and colorectal cancer or primary sclerosing cholangitis and hepatobiliary cancer.

Usually, it results from surgical resection, an autoimmune phenomenon, or an infiltrative process. Under certain circumstances, one may encounter a genetic etiology of hypoparathyroidism, often combined with myriad other syndromic manifestations.

Calcium sulfate beads are increasingly used as void fillers and prophylactic measures to prevent postoperative hardware infections. However, hypercalcemia secondary to rapid calcium absorption from calcium sulfate beads is generally an underrecognized adverse effect and likely underreported.

Diabetes affects both the peripheral and the central nervous systems. One of the unusual effects of hyperglycemia is involuntary movement, termed hyperglycemia-induced involuntary movement (HIIM).

We report a case of acute colonic pseudo-obstruction following dexmedetomidine use in a patient with alcohol withdrawal. He was treated with benzodiazepines first to control the withdrawal symptoms, then escalated to dexmedetomidine once delirium tremens ensued.
