Background

The intraoperative parathyroid hormone (IOPTH) assay is widely used in patients with primary hyperparathyroidism (PHPT). We investigated the usefulness of the IOPTH assay in Korean patients with PHPT.

Methods

We retrospectively reviewed the data of 33 patients with PHPT who underwent parathyroidectomy. Neck ultrasonography (US) and ^99mTc-sestamibi scintigraphy (MIBI scan) were performed preoperatively and IOPTH assays were conducted.

Results

The sensitivity of neck US and MIBI scans were 91% and 94%, respectively. A 50% decrease in parathyroid hormone (PTH) levels 10 minutes after excision of the parathyroid gland was obtained in 91% (30/33) of patients and operative success was achieved in 97% (32/33) of patients. The IOPTH assay was 91% true-positive, 3% true-negative, 0% false-positive, and 6% false-negative. The overall accuracy of the IOPTH assay was 94%. In five cases with discordant neck US and MIBI scan results, a sufficient decrease in IOPTH levels helped the surgeon confirm the complete excision of the parathyroid gland with no additional neck exploration.

Conclusion

The IOPTH assay is an accurate tool for localizing hyperfunctioning parathyroid glands and is helpful for evaluating cases with discordant neck US and MIBI scan results.

Abstract PDF PubReader

Ectopic adrenocorticotropic hormone (ACTH) syndrome is caused most frequently by a bronchial carcinoid tumor or by small cell lung cancer. Medullary thyroid carcinoma (MTC) is a rare etiology of ectopic ACTH syndrome. We describe a case of Cushing syndrome due to ectopic ACTH production from MTC in a 48-year-old male. He was diagnosed with MTC 14 years ago and underwent total thyroidectomy, cervical lymph node dissection and a series of metastasectomies. MTC was confirmed by the pathological examination of the thyroid and metastatic mediastinal lymph node tissues. Two years after his last surgery, he developed Cushingoid features, such as moon face and central obesity, accompanied by uncontrolled hypertension and new-onset diabetes. The laboratory results were compatible with ectopic ACTH syndrome. A bilateral adrenalectomy improved the clinical and laboratory findings that were associated with Cushing syndrome. This is the first confirmed case of ectopic ACTH syndrome caused by MTC in Korea.

Abstract PDF

Herein, a case of a solitary primary paraganglioma arising in the mesentery, found in a hypertensive 70-year-old woman, who presented with nausea and postprandial abdominal discomfort, is reported. Ultrasonography and computed tomography showed a hypervascular mass abutting the second portion of the duodenum. An exploratory laparotomy revealed a 5.5 x 5.3 x 5cm sized mass in the mesentery of the transverse colon, which was histologically proven to be a paraganglioma. No intraoperative hemodynamic changes developed, and the postoperative course was uneventful. To our knowledge, this is the first case of a paraganglioma arising in the mesentery reported in Korea. Considering the unusual locations and the associated operative risk, it is necessary to rule out the possibility of a functioning paraganglioma in the preoperative differential diagnosis of an abdominal mass.

Abstract PDF: We hereby report a case of a 62-year-old male patient who was misdiagnosed with adrenal insufficiency during the course of protein-losing enteropathy caused by superior mesenteric arterial thrombosis. The patient was suspected to have adrenal insufficiency due to hyponatremia and severe weakness. The cortisol responses to the initial challenge of 250microgram ACTH were inadequate (maximum serum cortisol level after ACTH challenge was 10.9microgram/dL), while the serum albumin concentration was 1.9g/dL. Subsequently, intravenous steroid therapy was given to the patient. However, after bowel resection, the serum albumin level increased to 3.4g/dL and the cortisol response to the follow-up rapid ACTH stimulation was completely normal. Accordingly, we discontinued steroid replacement and discharged the patient without any problem. In conclusion, measuring total serum cortisol in a patient with hypo-pro-teinemia may lead to misdiagnosis of adrenal insufficiency. In such cases, caution should be exercised in interpreting the results in terms of total serum cortisol level or measurement of serum free cortisol levels should be considered.
