RESUMEN
Molecular testing for cytologically indeterminate thyroid nodules has demonstrated benefit by reducing the need for diagnostic thyroidectomies and reducing costs. Its use is currently recommended in practice guidelines from the American Thyroid Association and the American Association of Endocrine Surgeons when clinically appropriate. Moreover, there is growing evidence that molecular testing may provide prognostic information and can detect targetable genetic alterations which may expand treatment options for refractory advanced thyroid cancers.

BACKGROUND: Differences in presenting symptoms of primary hyperparathyroidism and outcomes of parathyroidectomy between sexes have been described, but whether these can be assessed by perioperative use of a validated tool, such as the Pasieka Parathyroidectomy Assessment Score, is unknown. METHOD: All patients with primary hyperparathyroidism were asked to complete symptom assessment at the preoperative and postoperative visits. The assessment included a query for 13 Pasieka Parathyroidectomy Assessment Score parameters evaluated using a visual analog scale as described by Pasieka (summative score 0-1,300), and general quality of life and wellness. A review of a prospectively maintained database of primary hyperparathyroidism patients (January 2016-December 2019) was performed, and those who had a 6-month cure after initial parathyroidectomy were included. RESULTS: The study cohort was mostly women (77%, 541/701). The median preoperative Pasieka Parathyroidectomy Assessment Score was higher in women (155, 0-1,190) than in men (80.5, 0-855, P < .001), although there were similar rates of asymptomatic primary hyperparathyroidism (Pasieka Parathyroidectomy Assessment Score = 0, 12.5% vs 7%, P = .042). After curative parathyroidectomy, women reported a substantial reduction in symptomatology, with Pasieka Parathyroidectomy Assessment Score declining by 35% at initial postoperative visit (median, 155 vs 100, P < .001), further decreasing to 48% by 6 months (155 vs 80, P < .001). The Pasieka Parathyroidectomy Assessment Score in men did change but to a much smaller degree at both the initial postoperative visit (80.5 vs 70; P = .036) and at 6 months (80.5 vs 57.5; P = .048). CONCLUSION: When assessed with the Pasieka Parathyroidectomy Assessment Score, improvement in symptoms was clearly demonstrated for women after curative parathyroidectomy. Whether symptom improvement also occurs in men is less apparent but may be due to disparities in the development and validation of outcomes tools in general.

BACKGROUND: Normocalcemic hyperparathyroidism can occur, but surgery should not be considered until common etiologies for secondary hyperparathyroidism are comprehensively excluded. Calcium deficiency is an underrecognized cause of normocalcemic parathyroid hormone elevation, and we aim to determine if the implementation of a preoperative calcium challenge can be used to reduce unnecessary parathyroidectomy. METHODS: Consecutive patients referred for parathyroidectomy (1/21-6/22) with normocalcemia (serum calcium <10 mg/dL) and concurrently elevated parathyroid hormone levels were routinely treated with supplemental calcium and vitamin D3, and follow-up laboratory studies were assessed. RESULTS: A total of 29/314 (9%) patients had normocalcemic parathyroid hormone elevation with mean calcium, parathyroid hormone, and vitamin D 25OH levels of 9.5 ± 0.3 mg/dL, 109.9 ± 34.9 pg/mL, and 42.7 ± 23.8 ng/mL respectively. Confounding factors included estimated glomerular filtration rate <60 in 2, loop diuretic use in 4, and prior gastric bypass or gastric sleeve surgery in 4. Follow-up biochemical evaluation was available in 27 (92%); results were unchanged in 7 patients (26%); normalization of parathyroid hormone levels with persistently normal calcium levels occurred in 15 (55%), thus confirming secondary hyperparathyroidism and hypercalcemia with elevated parathyroid hormone levels (classic primary hyperparathyroidism) was diagnosed in 5 (19%). Parathyroid exploration has been completed for 3 of 5 patients with classic primary hyperparathyroidism to date. CONCLUSION: A preoperative calcium challenge was prospectively initiated in normocalcemic patients with parathyroid hormone elevation, and there was high compliance (92%). Short-interval calcium supplementation revealed â¼50% to have resolved secondary hyperparathyroidism due to insufficient calcium intake, which avoided unnecessary surgery. In contrast, classic patients were unveiled in 20%, allowing for prompt and correct surgical intervention.
