RESUMO
STUDY OBJECTIVE: In 2001, less than 20% of emergency medicine residents had more than $150,000 of educational debt. Our emergency medicine residents anecdotally reported much larger debt loads. Surveys have reported that debt affects career and life choices. Qualitative approaches are well suited to explore how and why such complex phenomena occur. We aim to gain a better understanding of how our emergency medicine residents experience debt. METHODS: We conducted individual semistructured interviews with emergency medicine residents. We collected self-reported data related to educational debt and asked open-ended questions about debt influence on career choices, personal life, future plans, and financial decisions. We undertook a structured thematic analysis using a qualitative approach based in the grounded theory method. RESULTS: Median educational debt was $212,000. Six themes emerged from our analysis: (1) debt influenced career and life decisions by altering priorities; (2) residents experienced debt as a persistent source of background stress and felt powerless to change it; (3) residents made use of various techniques to negotiate debt in order to focus on day-to-day work; (4) personal debt philosophy, based on individual values and obtained from family, shaped how debt affected each individual; (5) debt had a normative effect and was acculturated in residency; and (6) residents reported a wide range of financial knowledge, but recognized its importance to career success. CONCLUSION: Our emergency medicine residents' debt experience is complex and involves multiple dimensions. Given our current understanding, simple solutions are unlikely to be effective in adequately addressing this issue.

Uterine perforation is a rare but potentially life-threatening complication of gynecologic procedures. Serious complications include hemorrhage, infection, and injury to surrounding organ systems (eg, gastrointestinal, urological, vascular, etc.). Risk factors include advanced maternal age, prior gynecologic surgeries, and other anatomical features that impact the difficulty of accessing the uterine cavity. In this case report, we discuss a patient who presented to the emergency department (ED) with diffuse abdominal pain and vaginal bleeding that occurred after an elective dilation and curettage (D&C) for a termination of pregnancy. The diagnosis was suspected clinically and confirmed by imaging including ultrasound (US) and computed tomography (CT) of the abdomen and pelvis. The patient was managed operatively with a multidisciplinary approach including Gynecology, General Surgery, and Urology. The patient was stabilized and eventually discharged. Uterine perforation should be included in the differential for patients with a history of recent gynecologic instrumentation presenting with abdominal pain and vaginal bleeding. The stabilization of these patients requires aggressive volume resuscitation, controlling the source of bleeding, and emergent surgical consultation. Topics: Gynecology, vaginal bleeding, ultrasound, computed tomography.
RESUMO
Emphysematous pyelonephritis (EPN) is a rare and life-threatening sequalae of a urinary tract infection marked by a gas-producing necrotizing infection of the renal parenchyma requiring prompt treatment. It has been found to be correlated with uncontrolled diabetes mellitus and is more common in females due to their increased susceptibility to urinary tract infections. Early recognition and treatment of EPN are essential to improve the patient's prognosis and prevent further complications. In this case we highlight a progressive case of pyelonephritis complicated by emphysematous abscess formation requiring surgical management. A 49-year-old female with a history of diabetes, hypertension, asthma, and lupus who presented to the emergency department (ED) for evaluation of generalized weakness. Lactate was elevated and urinalysis was suggestive of infection. A computed tomography (CT) scan of the abdomen and pelvis revealed a large subcapsular fluid collection with multiple gas and air-fluid levels along the right kidney, as well as another suspected fluid collection adjacent to the upper pole of the right kidney. The findings suggested complicated pyelonephritis with emphysematous abscess formation. Urology was consulted and they suggested a perinephric drain be placed by interventional radiology (IR). The patient progressed well and was ultimately discharged days later in stable condition. Despite its rarity, healthcare providers should consider infectious processes such as EPN in the differential for generalized weakness and promptly initiate appropriate diagnostic and therapeutic measures. Topics: Weakness, sepsis, urology, CT scan.
RESUMO
BACKGROUND: Human heart failure is associated with decreased cardiac voltage-gated Na+ channel current (encoded by SCN5A), and the changes have been implicated in the increased risk of sudden death in heart failure. Nevertheless, the mechanism of SCN5A downregulation is unclear. A number of human diseases are associated with alternative mRNA splicing, which has received comparatively little attention in the study of cardiac disease. Splicing factor expression profiles during human heart failure and a specific splicing pathway for SCN5A regulation were explored in this study. METHODS AND RESULTS: Gene array comparisons between normal human and heart failure tissues demonstrated that 17 splicing factors, associated with all major spliceosome components, were upregulated. Two of these splicing factors, RBM25 and LUC7L3, were elevated in human heart failure tissue and mediated truncation of SCN5A mRNA in both Jurkat cells and human embryonic stem cell-derived cardiomyocytes. RBM25/LUC7L3-mediated abnormal SCN5A mRNA splicing reduced Na+ channel current 91.1±9.3% to a range known to cause sudden death. Overexpression of either splicing factor resulted in an increase in truncated mRNA and a concomitant decrease in the full-length SCN5A transcript. CONCLUSIONS: Of the 17 mRNA splicing factors upregulated in heart failure, RBM25 and LUC7L3 were sufficient to explain the increase in truncated forms and the reduction in full-length Na+ channel transcript. Because the reduction in channels was in the range known to be associated with sudden death, interruption of this abnormal mRNA processing may reduce arrhythmic risk in heart failure.

This is a case of a 35-year-old postpartum female presenting to the emergency department (ED) with acute onset chest pain and dyspnea with initial concern for acute ST-segment elevation myocardial infarct (STEMI). Her electrocardiogram (ECG) showed ST segment elevations in the lateral leads and inferior leads with depressions in the high lateral and septal leads. Given her post-partum status, spontaneous coronary artery dissection (SCAD) was part of the differential as well as other emergent processes. Upon cardiac catheterization, the patient was found to have 50% vasospasm in the left circumflex coronary artery. Her post-catheterization echocardiogram showed a normal ejection fraction (EF) without regional wall abnormalities. This is an interesting case of chest pain in a younger patient, without typical acute coronary syndrome (ACS) risk factors, presenting with a concerning ECG likely due to coronary vasospasm. We will discuss other atypical causes of STEMI patterns that should be considered in the differential and management of such patients. Topics: Sickle cell trait, STEMI, postpartum, vasospasm, ECG, cardiology.
RESUMO
The node of Ranvier is a site for ionic conductances along myelinated nerves and governs the saltatory transmission of action potentials. Defects in the cross-bridging and spacing of the cytoskeleton are a prominent pathological feature in diseases of the peripheral nerve. Electron tomography was used to examine cytoskeletal-cytoskeletal, membrane-cytoskeletal, and heterologous cell connections in the paranodal region of the node of Ranvier in peripheral nerves. Focal attachment of cytoskeletal filaments to each other and to the axolemma and paranodal membranes of the Schwann cell via narrow cross-bridges was visualized in both neuronal and glial cytoplasm. A subset of intermediate filaments associates with the cytoplasmic surfaces of supramolecular complexes of transmembrane structures that are presumed to include known and unknown junctional proteins. Mitochondria were linked to both microtubules and neurofilaments in the axoplasm and to neighboring smooth endoplasmic reticulum by narrow cross-bridges. Tubular cisternae in the glial cytoplasm were also linked to the paranodal glial cytoplasmic loop juxtanodal membrane by short cross-bridges. In the extracellular matrix between axon and Schwann cell, junctional bridges formed long cylinders linking the two membranes. Interactions between cytoskeleton, membranes, and extracellular matrix associations in the paranodal region are likely critical not only for scaffolding, but also for intracellular and extracellular communication.
