Review of intraoperative parathormone monitoring with the miami criterion: A 25-year experience

With the development of imaging and localization studies,focused parathyroidectomy with use of intraope-rative parathormone monitoring(IPM)is the mainstay of treatment for primary hyperparathyroidism at many health care centers both nationally and internationally.Focused parathyroidectomy guided by IPM allows for surgical excision of the offending parathyroid gland through smaller incisions.The Miami criterion is a protocol that uses a">50%parathormone(PTH)drop"from either the greatest pre-incision or pre-excision measurement of PTH in a blood sample taken 10 min following resection of hyperfunctioning glands.Following removal of the hyperfunctioning parathyroid gland,a>50%PTH drop at 10 min indicates completion of parathyroidectomy,and predicts operative success at6 mo.IPM using the Miami criterion has demonstrated equal curative rates of>97%,which is comparable to the traditional bilateral neck exploration.The focused approach,however,is associated with shorter recovery times,improved cosmesis,and lower risk of postoperative hypocalcemia.

Primary Hyperparathyroidia at the Abass Ndao Hospital Center: About 29 Cases

Introduction: In Senegal, there is very little data on primary hyperparathyroidism despite an overall upward epidemiological trend. The objective was to describe its epidemiological, clinical, therapeutic and evolutionary aspects. Materials and Methods: This was a cross-sectional, descriptive study, conducted over 5 years (from January 01, 2018 to December 31, 2022) at the National Abass Ndao Hospital Center and including all confirmed cases of primary hyperparathyroidism. Results: Twenty-nine patients were included with a female predominance (86.20%) and an average age of 48.10 ± 18.93 years. The discovery of hyperparathyroidism was fortuitous in 79.31% of cases. The main clinical manifestations were osteoarticular (62%) and urinary (34.5%). On average, serum calcium measured was 109.2 ± 7.92 mg/l, corrected serum calcium 111.3 ± 6.25 mg/l, urinary calcium 421.9 ± 96.45 mg/24h and parathormone at 145 ± 159.71 pg/ml. Among the patients, 25 had hypercalcemia (86.2%) and all had 24-hour hypercalciuria. The diagnosis was retained in view of the elevated parathyroid hormone (PTH) values in all patients. Cervical ultrasound objectified a parathyroid adenoma in 27.58% of cases and 12 patients or 46.2% had presented a scintigraphy in favor of a parathyroid adenoma. We found 01 cases of multiple endocrine neoplasia type 2. Bone densitometry performed in 10 patients found osteoporosis in 60% of cases (6 patients) and osteopenia in 40% of cases (4 patients). Surgical treatment was performed in 12 patients (41.4%). The histology of the surgical specimens was in favor of a parathyroid adenoma in all cases. Among the operated patients, the evolution was marked by a cure rate of 100%. Conclusion: The symptomatology of primary hyperparathyroidism remains mainly osteoarticular and urinary. Surgery has proven its effectiveness in our series. We insist on the systematic dosage of calcemia especially in women over 50 years and the promotion of morphological explorations.

Global longitudinal strain is superior to ejection fraction for detecting myocardial dysfunction in end-stage renal disease with hyperparathyroidism

BACKGROUND The estimation of left ventricular ejection fraction(LVEF)by 2D echocardiography(2D-ECHO)is the most used tool to assess LV systolic function(LVSF).Global longitudinal strain(GLS)has recently been suggested as a superior method for several evaluations.This study explored the association and prevalence of LV systolic dysfunction(LVSD)by using these methods in patients with end-stage renal disease(ESRD)and severe hyperparathyroidism(SHPTH);both associated with cardiovascular events(CEs).AIM To evaluate the myocardial function in patients with ESRD and SHPTH by using the GLS and LVEF measured through conventional 2D-ECHO.METHODS In 62 patients with ESRD and SHPTH,asymptomatic,and without a history of CEs,LVSF was evaluated by 2D-ECHO,obtaining the EF,by the Simpson biplane method,and GLS by speckle tracking.RESULTS The total patients with ESRD had a preserved LVEF(>50%)but abnormal GLS(<13.55%).Additionally,multivariate analysis showed an independent association of GLS and serum parathyroid hormone(PTH),LV mass index,and hemoglobin.Also,PTH was independently associated with lateral e'wave and tricuspid regurgitation velocity.CONCLUSION In patients with SHPTH linked to ESRD,the use of GLS by 2D-ECHO is a more sensitive tool than LVEF for detecting LVSD.
