AI Article Synopsis
- Tongue squamous cell carcinoma (TSCC) is a serious oral cancer that often leads to metastasis and poor outcomes, with docetaxel being a common first-line treatment despite its side effects, including rare cases of low potassium levels.
- A patient undergoing chemotherapy with docetaxel and cisplatin experienced severe hypokalemia, dropping his potassium level to 1.85 mmol/L, which severely impaired his muscle strength.
- After treatment involving potassium supplementation, the patient recovered from the critical hypokalemia and was discharged in stable condition, highlighting the need for vigilance from healthcare providers in monitoring side effects of chemotherapy.
Article Abstract
Background: The tongue squamous cell carcinoma (TSCC) is an oral malignant tumor arising from the squamous epithelium of the tongue mucosa, characterized by a high malignant degree, invasive growth, early lymph node metastasis, and poor prognosis. Paclitaxel, represented by docetaxel, is now the standard first-line treatment for head and neck squamous cell carcinoma. Docetaxel, which belongs to the class of drugs known as paclitaxel, is an antitumor drug that inhibits cell mitosis and proliferation. Its adverse effects include myelosuppression, hair loss, gastrointestinal reactions, fluid retention, and allergic reactions. However, hypokalemia is rare, most cases are mild or moderate, and severe hypokalemia is seldom reported.
Case Summary: During chemotherapy with docetaxel and cisplatin, a patient with TSCC developed severe hypokalemia. His potassium level was found to have been reduced to 1.85 mmol/L at the most critical situation. The patient had grade 1 muscle strength in all four limbs and could not perform any action, which was considered to be a sign of severe hypokalemia. Measures taken included intravenous infusion micro-pump, intravenous injection, and oral potassium supplement, which gradually improved muscle strength and serum potassium levels. The patient survived the critical period of severe hypokalemia after chemotherapy. He was generally in good condition following treatment and discharged in stable condition.
Conclusion: Docetaxel may cause severe hypokalemia with hypomagnesemia and the mechanism for this is not yet known to researchers yet. This means that nurses specializing in chemotherapy must exercise a high degree of responsibility, closely observe the patient's reaction to the anticancer medication, notice any symptoms of adverse effects early. It is necessary to be considerate regarding individual differences between patients when selecting chemotherapy regimens and adhere to the principle of individualized treatment. Following multiple cycles of chemotherapy, patients should be aware of the accumulation of toxic side effects and receive blood tests reviewed within 24 hours of completion. It is essential to monitor electrolyte levels in patients suffering from severe gastrointestinal reactions to avoid complications that may result in death.

Thus, a correctly repeated blood sample should show lower potassium levels than a haemolysed one. This study aimed to determine the prevalence of haemolysed samples with potassium levels below the reference range and whether this predicts hypokalemia in repeated collections.

Anorexia nervosa (AN) is an eating disorder characterized by restriction of energy intake leading to a significantly low body weight, and intense fear of gaining weight. Severe electrolyte changes such as hypokalemia and hypophosphatemia; and alterations in water metabolism such as hyponatremia and edema, can occur in patients with AN. Hypokalemia and chronic volume depletion may lead to acute kidney injury (AKI) and chronic kidney disease (CKD).

Article Synopsis
- Non-neoplastic hypercortisolaemia, or pseudo-Cushing's syndrome (PCS), can occur due to various health conditions like depression, obesity, and diabetes, linked to overactivity of the hypothalamic-pituitary-adrenal axis.
- A 66-year-old woman exhibited symptoms such as weakness, weight loss, and poorly controlled hypertension, which led to the discovery of pheochromocytoma, a tumor that causes hormone overproduction, upon further testing.
- After undergoing surgery to remove the tumor and receiving supportive treatment, her symptoms improved significantly, confirming the diagnosis of PCS rather than traditional Cushing's syndrome.
