Adrenal Myelolipoma Masquerading as an Adrenal Malignancy.

An adrenal myelolipoma presenting with suspicious features may pose a diagnostic challenge to surgeons and endocrinologists. In this case report of an adult patient with undiagnosed congenital adrenal hyperplasia presenting with bilateral adrenal masses, we review his radiographic and clinical findings which were highly suspicious for adrenal malignancy. Features of adrenal myelolipoma that may resemble malignant lesions are reviewed. This case report highlights important features of adrenal myelolipoma that the surgeon and endocrinologist should be aware of. The importance of avoiding overtreating adrenal myelolipomas presenting as tumors of uncertain malignant potential is crucial.

Suspected Primary Adrenal Lymphoma (PAL) Associated With Hemophagocytic Lymphohistiocytosis (HLH).

Adrenal incidentalomas, masses noted on imaging performed for other purposes, are common, with 10% to 15% presenting as bilateral adrenal masses. These cases can be challenging as the differential diagnosis is broad, including metastatic disease, primary adrenal lymphoma (PAL), or infection, and often requiring a biopsy if initial biochemical workup is unrevealing. We present here a relevant case description, laboratory and radiologic imaging studies, and discussion of literature. A 62-year-old Korean woman presented with altered mental status and fevers. She was found to have bilateral adrenal incidentalomas and retained acupuncture needles. Adrenal workup did not show biochemical evidence of hormonal excess. Infectious workup was unrevealing, as was a metal/toxin workup due to retained acupuncture needles. Fevers and episodes of hypotension persisted which prevented the patient from obtaining an adrenal biopsy. Bone marrow biopsy was obtained for pancytopenia and revealed B-cell lymphoma with large cell morphology and few histiocytes with hemophagocytosis, raising concern for lymphoma-induced hemophagocytic lymphohistiocytosis (HLH). PAL associated with HLH was highly suspected in our patient, given the large (7 cm) bilateral adrenal masses and bone marrow biopsy findings of lymphoma. The patient was treated for diffuse large B-cell lymphoma, with clinical improvement. PAL is a rare but aggressive lymphoma with few reported cases. It should be considered in the differential for both unilateral and bilateral adrenal masses. An early diagnosis is crucial as the main treatment is chemotherapy rather than surgery and it confers a significant survival benefit.

A case of idiopathic thyroid abscess caused by Escherichia coli.

Suppurative thyroiditis with an abscess is a rare form of thyroiditis that can present as a diagnostic challenge. Its rarity is attributed to unique features of the thyroid gland that make it resistant to infection. Delay in diagnosis often can lead to morbid complications from the progression of the infection. Although more likely to be caused by gram-positive bacteria, gram-negative organisms are also known to cause this infection which often requires surgical treatment. The authors present a case of thyroid abscess from Escherichia coli from an unknown source.

Concurrent Diabetic Ketoacidosis in Hypertriglyceridemia-Induced Pancreatitis: How Does It Affect the Clinical Course and Severity Scores?

OBJECTIVES: Concurrent diabetic ketoacidosis (DKA) is highly prevalent in patients with hypertriglyceridemia-induced pancreatitis (HP). Diabetic ketoacidosis could potentially complicate the diagnosis, management, and prognosis of HP. This study aimed to directly compare the clinical course of HP with and without DKA and assess the outcomes of frequently used severity-prediction scores in such population. METHODS: We retrospectively analyzed 140 patients with HP; 37 patients (26.4%) had concurrent DKA. We compared epidemiologic characteristics, initial laboratory values, and clinical courses between the DKA and non-DKA groups. Bedside Index for Severity in Acute Pancreatitis score, Sequential Organ Failure Assessment score, Ranson criteria, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and Marshall score were calculated and compared between groups. RESULTS: We observed more acute kidney injury in the DKA group. Patients with DKA more likely required intensive care unit admission, received intravenous insulin, and were discharged on subcutaneous insulin. Ranson criteria and APACHE II score were significantly higher with DKA. CONCLUSIONS: Concurrent DKA does not affect length of stay, in-hospital mortality, and readmission rate in patients with HP. Higher Ranson criteria and APACHE II score likely reflected derangement of clinical parameters secondary to DKA rather than true severity of pancreatitis in such population.

Coronary Atherectomy in the United States (from a Nationwide Inpatient Sample).

Contemporary real-world data on clinical outcomes after utilization of coronary atherectomy are sparse. The study cohort was derived from Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from year 2012. Percutaneous coronary interventions including atherectomy were identified using appropriate International Classification of Diseases, 9th Revision diagnostic and procedural codes. Two-level hierarchical multivariate mixed models were created. The primary outcome was a composite of in-hospital mortality and periprocedural complications; the secondary outcome was in-hospital mortality. Hospitalization costs were also assessed. A total of 107,131 procedures were identified in 2012. Multivariate analysis revealed that atherectomy utilization was independently predictive of greater primary composite outcome of in-hospital mortality and complications (odds ratio 1.34, 95% confidence interval 1.22 to 1.47, p <0.001) but was not associated with any significant difference in terms of in-hospital mortality alone (odds ratio 1.22, 95% confidence interval 0.99 to 1.52, p 0.063). In the propensity-matched cohort, atherectomy utilization was again associated with a higher rate of complications (12.88% vs 10.99%, p = 0.001), in-hospital mortality +a ny complication (13.69% vs 11.91%, p = 0.003) with a nonsignificant difference in terms of in-hospital mortality alone (3.45% vs 2.88%, p = 0.063) and higher hospitalization costs ($25,341 ± 353 vs $21,984 ± 87, p <0.001). Atherectomy utilization during percutaneous coronary intervention is associated with a higher rate of postprocedural complications without any significant impact on in-hospital mortality.

In-Hospital Outcomes of Atherectomy During Endovascular Lower Extremity Revascularization.

Contemporary data on clinical outcomes after utilization of atherectomy in lower extremity endovascular revascularization are sparse. The study cohort was derived from Healthcare Cost and Utilization Project nationwide inpatient sample database from the year 2012. Peripheral endovascular interventions including atherectomy were identified using appropriate International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic and procedural codes. The subjects were divided and compared in 2 groups: atherectomy versus no atherectomy. Two-level hierarchical multivariate mixed models were created. The coprimary outcomes were in-hospital mortality and amputation; secondary outcome was a composite of in-hospital mortality and periprocedural complications. Hospitalization costs were also assessed. Atherectomy utilization (odds ratio, 95% CI, p value) was independently predictive of lower in-hospital mortality (0.46, 0.28 to 0.75, 0.002) and lower amputation rates (0.83, 0.71 to 0.97, 0.020). Atherectomy use was also predictive of significantly lower secondary composite outcome of in-hospital mortality and complications (0.79, 0.69 to 0.90, 0.001). In the propensity-matched cohort, atherectomy utilization was again associated with a lower rate of amputation (11.18% vs 12.92%, p = 0.029), in-hospital mortality (0.71% vs 1.53%, p 0.001), and any complication (13.24% vs 16.09%, p 0.001). However, atherectomy use was also associated with higher costs ($24,790 ± 397 vs $22635 ± 251, p <0.001). Atherectomy use in conjunction with angioplasty (with or without stenting) was associated with improved in-hospital outcomes in terms of lower amputation rates, mortality, and postprocedural complications.
