IMPROVING AFTER-HOURS CALLS TO ENDOCRINOLOGY FELLOWS.

OBJECTIVE: To analyze the frequency and nature of after-hours calls to endocrinology fellows and employ interventions to direct appropriate care to primary endocrinologists. METHODS: The on-call fellows logged calls that came to them during the after-hours and marked them as urgent or nonurgent. We analyzed these calls and then implemented interventions to educate patients on calls that can wait until the next business day. We also trained providers to provide script refills during clinic visits and educated fellows on how to best manage and document these after-hours calls. RESULTS: From July to August 2017, 100 calls were logged. The average number of calls per 24 hours was 1.61, and 47% were marked nonurgent. From January to March 2018, the fellows logged 0.64 calls per 24 hours, and 51% were logged as nonurgent. Most of these calls were for insulin and testing supply refills. CONCLUSION: Many after-hours calls to the fellows were nonurgent and could have waited until the next business day. Our continuing interventions aim at improving both physician and patient satisfaction, as well as patient care.

Fever of Unknown Origin: Could It Be a Pheochromocytoma? A Case Report and Review of the Literature.

Pheochromocytomas are rare tumors that arise from the adrenal medulla, with an incidence of less than 1 per 100,000 person-years. These tumors are characterized by excess catecholamine secretion and classically present with the triad of headaches, palpitations, and sweating episodes. However, the clinical presentation can be quite variable. Herein, we present a patient who presented with persistent fevers. An adrenal mass was incidentally discovered during the extensive investigation for the fever of unknown origin. Consequently, blood and urine tests were done and found to be consistent with a pheochromocytoma. The resection of this pheochromocytoma resulted in resolution of fevers. It is hypothesized that fevers in patients with pheochromocytomas occur due to the excess catecholamine or possibly due to interleukins. This clinical presentation serves as a learning point that adrenal incidentalomas in the setting of fever of unknown origin should not be ignored. It also reminds clinicians that pheochromocytomas which present with fevers may have tumor necrosis and many such patients are at risk for multisystem crises.

Mantle Cell Lymphoma in the Thyroid: A Rare Presentation.

BACKGROUND: While 2% of all extranodal Non-Hodgkin Lymphomas present in the thyroid, there exists insufficient data to describe the incidence of mantle cell lymphoma in the thyroid. A case series of 1400 patients revealed that <1% of thyroid lymphomas may be MCL; hence better understanding of the disease course is essential. PATIENT FINDINGS: A 65-year-old female was referred for a multinodular goiter. Multiple fine needle aspirations from the dominant right nodule were consistent with Hashimoto's thyroiditis and flow cytometry was negative. Due to progressing dysphagia, she underwent total thyroidectomy. SUMMARY: Pathology revealed MCL with mantle zone growth pattern in the right thyroid. Flow cytometry showed monoclonal B cells comprising 9% of total cells. The Ki-67 index was 10%. She was diagnosed as having stage IIE MCL and offered conservative management by medical oncology, given that she had no B symptoms. CONCLUSION: Though chemotherapy is the treatment of choice in MCL, a subset of patients with low-grade disease may be observed. As in our patient, mantle zone growth pattern and a Ki-67 index < 10% suggest a favorable prognosis. A diagnosis of primary MCL in the thyroid remains rare and staging modalities as well as treatment options continue to evolve.
