Hirsutism and hyperandrogenism in premenopausal women are most often associated with polycystic ovarian syndrome. We present a case of progressive, severe hyperandrogenism with negative imaging identified on surgical histopathology as being due to a Leydig cell tumor (LCT), thus illustrating localization challenges associated with these small tumors.
Laboratory investigations included testosterone, dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone, 24-hour urine cortisol, and prolactin. Imaging included pelvic ultrasound, adrenal magnetic resonance imaging, and computed tomography. Ovarian vein sampling was not available.
A 42-year-old woman presented with frontal alopecia, voice deepening, coarse facial hair, and amenorrhea on a background of lifelong oligomenorrhea. Peak testosterone was 30.2 nmol/L (female normal range is <2.0 nmol/L) with normal dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, prolactin, 2ative with a LCT found only after oophorectomy. LCTs are rare ovarian stromal tumors and while 50 to 70% of these tumors produce androgen, size and clinical severity may not be well correlated. This case report illustrates that despite an association with substantially elevated androgen levels, the small size of LCTs can result in localization challenges.
Pheochromocytoma is diagnosed biochemically by demonstrating an excessive production of catecholamines and their metabolites in the blood and urine. However, these tests are at times fraught with false-positive results due to drug effects. We report here a patient with markedly elevated urinary metanephrines associated with the use of eletriptan for migraine treatment.
A literature search was conducted using the PubMed and Google Scholar databases for eletriptan and false positive metanephrine elevation. Urine and plasma metanephrine tests were performed via liquid chromatography/tandem mass-spectrometry.
A 29-year-old man with migraine recently started on eletriptan was evaluated for a worsening headache. Initially his blood pressure was 220/160 mm Hg with a creatinine of 1.9 mg/dL. Phenazine methosulfate He was treated with intravenous nicardipine. His lab tests showed normal aldosterone/plasma renin activity ratio, midnight salivary cortisol, thyroid function, and urinary drug screen. A 24-hour urine metanephrine level at affect the urine assays, but the exact mechanism causing elevated urine metanephrines/normetanephrines is not clear.
To describe a case of Graves disease (GD) and coexistent pancytopenia associated with autoimmune vitamin B
deficiency. While thyrotoxicosis and antithyroid drugs can cause pancytopenia, other autoimmune conditions such as vitamin B
deficiency can occur, leading to severe anemia and pancytopenia.
A 19-year-old female with GD treated with methimazole presented with thyrotoxicosis and evidence of pancytopenia. Diagnostic studies included a complete blood cell count, peripheral blood smears, thyroid function tests, and a bone marrow biopsy.
White blood cells were 2.4 × 10
cells/L (reference range [RR] is 3.4 to 9.6 × 10
cells/L), hemoglobin was 7.9 g/dL (RR is 11.6 to 15.0 g/dL), neutrophil count was 1.2 × 10
cells/L, and platelets were 84 × 10
cells/L (RR is 157 to 371 × 10
cells/L). Thyroid-stimulating hormone was <0.01 mIU/L (RR is 0.50 to 4.30 mIU/L), free thyroxine was 3.7 ng/dL (RR is 1.0 to 1.6 ng/dL), and total triiodothyronine was 221 ng/dL (RR is 91 to 218 ng/dL). Due to suspicionwhen these patients are treated with antithyroid drugs known to cause bone marrow suppression.National data indicate about 50% of junior faculty leave a School of Medicine (SOM) within eight years of hire. The long-term goal of the study was to determine innovative strategies for promoting SOM faculty retention. The study objective was to determine factors influencing SOM faculty to exit, and what would encourage them to stay or return. All faculty exiting the University of New Mexico (UNM) SOM were surveyed and their responses analyzed to the following items (a) If something could have been done differently that might have resulted in staying at UNM, what would it have been? (b) What would need to change at UNM SOM for you to return? and (c) general comments offered. Qualitative analysis of open-ended responses used an iterative process and systematic thematic approach and NVivo software. 173 faculty respondents surveyed between July 2017 and June 2019 included 86 women, 33 non-Caucasians, and 14 Hispanics. A total of 110 faculty reported an MD degree and 117 were assistant professors. Seventy-eight faculty were on clinician educator track. The 367 responses to the three questions were categorized into 10 themes. The most common themes included (a) people (leadership and others) and workplace culture (25.1% of responses); (b) extent of career support and resources (15.3%); (c) organizational systems and administration (13.6%); and (d) faculty feelings of autonomy and value (10.9%). Exiting faculty frequently discussed the need for a change of leadership and changes in organizational climate and culture, which may have influenced their willingness to stay or to return to UNM SOM. To retain faculty, SOM leaders need to strengthen and/or modify organizational climate and culture components. Innovative strategies for this purpose may include organizational interventions followed by evidence-based leadership training programs, and the use of exit surveys for monitoring interventions.We replicated and extended Mitteer, Greer, Fisher, and Cohrs (2018) by examining the effects of a video model on inputting data into GraphPad Prism, which is a necessary skill for graph construction. We used a concurrent multiple-probe-across-behavior design with two behavior technicians to assess data-input and graphing skills separately prior to and during access to relevant video models. We evaluated the generality of the training procedures by assessing both skills during data-input-plus-graphing sessions without access to the video models. The video models resulted in mastery of data-input and graphing skills when assessed individually. We observed training effects generalize to data-input-plus-graphing sessions once behavior technicians experienced all relevant video models. These results suggest that individuals should view both data-input and graphing video models prior to depicting single-case design data in Prism but that these skills can maintain at high levels of accuracy without continued access to the training materials.
