Cushing's Syndrome Due to a Functional Thymic Neuroendocrine Tumor in Multiple Endocrine Neoplasia Type 1 Syndrome.

Multiple endocrine neoplasia type 1 (MEN 1) syndrome is characterized by endocrinopathies and could be associated with thymic neuroendocrine tumors (NET). On rare occasions, they can be functional adrenocorticotropic hormone-secreting thymic carcinoid leading to Cushing's syndrome. In this report, we describe a case of adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome due to a thymic NET associated with MEN type 1 syndrome. We highlight its aggressive clinical course, the premise for a high index of suspicion for an ectopic ACTH secretion, and the need for early surgical resection combined with medical therapy and alternative treatments.

A Cardioversion and Renal Dysfunction Cascade: Cardioversion for Atrial Fibrillation, Acute Kidney Injury, and Recurrence of Atrial Fibrillation.

A 62-year-old woman with hypertension presented with progressively worsening shortness of breath due to acute decompensated heart failure with atrial fibrillation in rapid ventricular response. During admission, she was managed with diuretics, goal-directed medical therapy for heart failure with successful DCCV (Direct current cardioversion) for first episode atrial fibrillation. However, one day after discharge, the patient presented with a recurrence of dyspnea with atrial fibrillation in rapid ventricular response and a reduction in urine output with elevated serum creatinine. In this case report, we describe the syndrome of acute kidney injury following cardioversion for atrial fibrillation known as AFCARD (Atrial Fibrillation Cardioversion Associated with Renal Dysfunction), highlight its incidence and reflect on renal dysfunction subserving the recurrence of atrial fibrillation after successful DCCV.

Factors associated with bleeding events in patients on rivaroxaban for non-valvular atrial fibrillation: A real-world experience.

BACKGROUND: Rivaroxaban is a direct oral anticoagulant (DOAC) approved for the treatment of non-valvular atrial fibrillation (NVAF). Data related to the risk factors associated with rivaroxaban-induced bleeding in patients with NVAF remain scarce in the community setting. We sought to investigate these bleeding risk factors in a racially diverse patient population. METHODS: We conducted a single-center, retrospective study based on a chart review of patients who received rivaroxaban from our outpatient pharmacy from January 2015 to April 2018 for NVAF. Any reported bleeding event (BE) was recorded as either major or minor bleeding event. Demographic and clinical data were collected and analyzed. RESULTS: Of the 327 patients included in our analysis, 105 (32%) were female, and the mean age was 62 ± 12 years. Among the included patients, 176 (54%) patients were black, 71 (22%) were white, 51 (15.6%) were Hispanic, 13 (4%) were Asian, and 15 (4.6%) belonged to other races. 89 (27.2%) of the patients had co-prescription of aspirin. A total of 24 (7.3%) patients developed BE, out of which 9 (2.7%) patients had a major BE, and 15 (4.5%) patients had minor BE. Non-fatal gastrointestinal bleeding and epistaxis were the most common type of BE. On multivariable analysis, concurrent aspirin use (81 to 325 mg) (P = 0.03; odds ratio (OR) 2.60 [1.08-6.28]) and increasing age (P = 0.00; OR 1.06 [1.01-1.11]) were independent predictors of BE. CONCLUSION: In community practice, aspirin co-prescription is common among NVAF patients prescribed rivaroxaban. Increasing age and concurrent aspirin use are independent predictors of BE.

Carotenemia: A Case Report.

Carotenemia is a condition characterized by yellow-orange discoloration of the skin usually secondary to excessive ingestion of foods rich in carotene. It occurs in the absence of yellow discoloration of the sclera. Carotenemia is a benign condition; hence, further diagnostic testing is unnecessary. We present a case of carotenemia secondary to excessive ingestion of papaya and mango.
