An Unusual Presentation of Membranous Nephropathy in an Adult With Arthrogryposis: A Case Report.

Membranous nephropathy (MN) is an autoimmune condition that is a common cause of nephrotic syndrome in nondiabetic adults. In this study, we highlight a case of a 22-year-old male with a past medical history of arthrogryposis multiplex congenita (AMC) who initially presented with right flank pain and hematuria. Subsequent workup revealed significant proteinuria with biopsy-proven primary MN. Early detection of the disease is critical to establish treatment promptly and prevent complications such as those resulting from a hypercoagulable state.

Spindle Cell Malignancy and Asbestos Exposure: A Case Report.

We outline the presentation of a 68-year-old woman who received a chest radiograph due to her insurance requirements, resulting in the discovery of a left-sided pleural effusion. The effusion was further characterized as loculated on subsequent imaging. Thoracentesis yielded exudative fluid, leading to the patient undergoing video-assisted thoracoscopic surgery (VATS). During this procedure, a cystic mass was visualized, with the conversion of the operation to an open thoracotomy and left lower lobe lobectomy. Pathology was positive for spindle cell sarcoma. A thorough history of the patient revealed a decades-long occupational exposure to asbestos. The significance of this report is to illustrate the clinical presentation, immunohistochemical characteristics, and management of a rare spindle cell malignancy. Our case also raises the importance of screening patients on an individualized, shared decision-making basis.

Detecting Multiple Driver Mutations in a Patient with Essential Thrombocythemia.

BACKGROUND Three driver mutations have been identified in patients with essential thrombocythemia - JAK2 V617F, CALR, and MPL. Out of these, JAK2 V617F is mostly common. These mutations are thought to be mutually exclusive; therefore, the initial workup may not include the identification of all mutations separately. CASE REPORT We present a case of a 55-year-old woman who was referred to the hematology clinic for an elevated platelet count noted when she was hospitalized for a renal stone. The patient was asymptomatic. A workup was initiated for essential thrombocythemia, and she was tested for JAK2 V617F mutation using an allele-specific polymerase chain reaction (AS-PCR) test in peripheral blood, which came back positive. The variant allele frequency was 2%. She underwent a bone marrow biopsy, and next-generation sequencing (NGS) showed a CALR mutation. A 52 bp deletion-type mutation was detected in the CALR gene on exon 9, with a variant allele frequency of 7%. The NGS did not detect JAK2 mutation due to its low sensitivity. She was started on aspirin alone as she was less than 60 years old and had no history of thrombotic events. The patient has been following up with the hematology clinic for the last 2 years and has not had any thrombotic events. CONCLUSIONS We propose that in patients with a low JAK2 V617 allele variant, testing for other driver mutations should be performed. In our patient, JAK2 mutation could be clonal hematopoiesis of indeterminate potential; therefore, the dominant mutation (CALR) would determine the disease phenotype.

Visual Analytics Dashboard Promises to Improve Hypertension Guideline Implementation.

BACKGROUND: Primary care management of hypertension under new guidelines incorporates assessment of cardiovascular disease risk and commonly requires review of electronic health record (EHR) data. Visual analytics can streamline the review of complex data and may lessen the burden clinicians face using the EHR. This study sought to assess the utility of a visual analytics dashboard in addition to EHR in managing hypertension in a primary care setting. METHODS: Primary care physicians within an urban, academic internal medicine clinic were tasked with performing 2 simulated patient encounters for hypertension management: the first using standard EHR, and the second using EHR paired with a visual dashboard. The dashboard included graphical blood pressure trends with guideline-directed targets, calculated atherosclerotic cardiovascular disease risk score, and relevant medications. Guideline-appropriate antihypertensive prescribing, correct target blood pressure goal, and total encounter time were assessed. RESULTS: We evaluated 70 case simulations. Use of the dashboard with the EHR compared with use of the EHR alone was associated with greater adherence to prescribing guidelines (95% vs. 62%, P < 0.001) and more correct identification of blood pressure target (95% vs. 57%, P < 0.01). Total encounter time fell an average of 121 seconds (95% confidence interval 69-157 seconds, P < 0.001) in encounters that used the dashboard combined with the EHR. CONCLUSIONS: The integration of a hypertension-specific visual analytics dashboard with EHR demonstrates the potential to reduce time and improve hypertension guideline implementation. Further widespread testing in clinical practice is warranted.
