BACKGROUND: Patients with permanent postsurgical hypoparathyroidism, a complication of total thyroidectomy, often require high calcium supplementation with vitamin D to maintain serum calcium levels. The epidemiology of calcium-alkali syndrome (CAS) in patients with hypoparathyroidism after total thyroidectomy remains unclear. This study aimed to investigate the incidence of hypercalcemia, renal impairment, metabolic alkalosis, and CAS in patients treated for presumed hypoparathyroidism after total thyroidectomy. METHODS: Twenty-seven patients with neck cancers who underwent total thyroidectomy without parathyroid autotransplantation between January 2010 and October 2013 at our hospital were consecutively included. All patients received calcium lactate and alfacalcidol for postsurgical hypocalcemia. We defined hypercalcemia as a corrected serum calcium level (cCa) ≥10.5 mg/dL, metabolic alkalosis as a difference in serum sodium and serum chloride ([sNa-sCl]) ≥39 mEq/L, and renal impairment as a ≥50% increase in serum creatine and/or ≥35% decrease in estimated glomerular filtration rate (eGFR) compared to baseline. RESULTS: cCa peaked (11.1 ± 1.5 mg/dL) at a median of 326 days (interquartile range 78-869) after surgery. At peak cCa, [sNa-sCl] was significantly higher (p < 0.01), and eGFR was significantly lower (p < 0.01) than that at baseline. Fifteen patients (55.6%) had hypercalcemia, 19 (70.3%) had alkalosis, 12 (44.4%) had renal impairment, and 9 (33.3%) had CAS. Patients with CAS (mean age 67.1 ± 10.8 years) were older than those without CAS (56.7 ± 13.6 years, p = 0.06). The mean dose of alfacalcidol in the CAS group (3.1 ± 1.2 µg/day) was significantly larger than that in the non-CAS group (2.1 ± 1.0 µg/day, p = 0.03). CONCLUSIONS: This retrospective study reveals the high incidence of CAS in patients with hypoparathyroidism after total thyroidectomy. Furthermore, these findings suggest that the serum calcium level, acid-base balance, and renal function should be closely monitored in patients with postsurgical hypoparathyroidism who receive large doses of active vitamin D.

Thrombolytic therapy is an effective treatment for acute ischemic stroke and provides benefits and improvements that lead to better neurological outcomes. However, thrombolytic therapy with recombinant tissue plasminogen activator (r-tPA) in hemodialysis (HD) patients is limited because HD patients have a higher risk of bleeding. We report a case of a 75-year-old HD patient who presented with sudden aphasia during HD treatment. She was brought to the hospital for treatment for infarction. Following thrombolytic therapy, we achieved re-opening without complications. To our knowledge, no report has been published describing the patients who had a stroke during a maintenance HD session and were treated with r-tPA successfully. Although the number of HD patients treated with r-tPA is small and requires further investigation, thrombolytic therapy can be an alternative option. After weighing the risks and benefits and assessing each patient carefully, the use of r-tPA should be considered, even in HD patients.

Tumor lysis syndrome (TLS) is a metabolic disorder that is generally associated with a malignancy leading to hyperuricemia, hyperphosphatemia, and acute kidney injury. On the other hand, we sometimes encounter these phenomena in nonmalignant disease, which has been referred to as tumor lysis-like syndrome in some studies. We herein experienced a case in which tumor lysis-like syndrome occurred in the course of therapy for eosinophilic disease of the lung, a nonmalignant disease. Even in nonmalignant disease, massive cell lysis induced by therapy can cause phenomena such as TLS or tumor lysis-like syndrome.
