A Case of Spontaneous Mesenteric Hematoma

By Andrew Yocum, MD &Andrew King, MD   A 69-year-old woman with a past medical history of multiple sclerosis, hypertension, hyperlipidemia, remote cerebral vascular accident, and a known abdominal aortic aneurysm was brought to the emergency department by EMS complaining of abdominal pain. Her AA was stable on imaging four months prior to presentation with a measurement of 3.8 cm.   The patient had intermittent generalized abdominal pain over the previous four weeks that resolved without intervention. This episode began almost 24 hours prior to presentation after the patient finished eating. She had a constant, generalized abdominal pain since that time. The patient said the pain was worst in the left lower quadrant. She described the pain as 8/10, sharp, and nonradiating with associated anorexia. She denied any nausea, vomiting, changes in bowel movements, hematochezia, melena, fevers, or chills. She also denies any urinary frequency, dysuria, or hematuria, but does intermittently self-catheterize because of her multiple sclerosis.   The patient’s primary physician prescribed her a course of steroids and Levofloxacin eight days prior to presentation for a cough, which resolved her symptoms.   The patient had a colonoscopy in 2009 that revealed a 4 mm sessile polyp, which was resected and found to be tubular adenoma. She was noted to have a tortuous sigmoid colon at that time.   The patient was normotensive but pale in the ED. Her ...

In this study, 5% w/v SMP dispersion was acidified to pH 2.4–3.0 using citric acid and heated at different conditions. Lowering pH resulted in dissolution of colloidal calcium phosphate from casein micelles, corresponding to lowered turbidity and reduced hydrodynamic diameter of dispersions. When heated for 10 min at different temperatures, 70 °C was the most effective to produce transparent dispersions; whereas a shorter heating time between 2 and 60 min was desired at 90 °C. The decreased turbidity after heating was attributed to weakened hydrophobic interaction between casein molecules based on f...

CONCLUSION: In procedures performed using ICA distal filtering CPD systems, RAO as a complication of CAS (performed for severe stenosis) showed a relationship to ECA-supplied OA. For older patients, simultaneous use of ICA-ECA CPDs might help prevent such complications. PMID: 31606959 [PubMed - in process]

CONCLUSION: Most CPAFs identified on CCTA have a favorable prognosis. Observation with OMT is usually an appropriate strategy. Fistula size is a possible determinant for surgical treatment. PMID: 31606954 [PubMed - in process]

Authors: Lee JW, Hur JH, Yang DH, Lee BY, Im DJ, Hong SJ, Kim EY, Park EA, Jo Y, Kim J, Park CH, Yong HS Abstract Cardiovascular magnetic resonance imaging (CMR) is expected to be increasingly used in Korea due to technological advances and the expanded national insurance coverage of CMR assessments. For improved patient care, proper acquisition of CMR images as well as their accurate interpretation by well-trained personnel are equally important. In response to the increased demand for CMR, the Korean Society of Cardiovascular Imaging (KOSCI) has issued interpretation guidelines in conjunction with the Korean Soci...

Abdallah, Mohamed S.Mohamed AhmedAbstractEthyl 2-(1,2,3,6-tetrahydro-6-oxo-2-thioxopyrimidin-4-yl)ethanoate (EOTPE) was synthesized by a facile and cost-effective method. The structure confirmation of the synthesized EOTPE was performed by different spectroscopic methods. The corrosion inhibition action of EOTPE in pickling acids (1.0 N HCl and1.0 N H2SO4) at different temperatures (30–60 °C) was tested by various surface and corrosion methods, including open circuit potential (...

The purpose of this study was to evaluate the relationship between the circadian profile of the vasorelaxing substances calcitonin gene-related peptide (CGRP) and epoxyeicosatrienoic acids (EETs) and the vasconstrictive agent endothelin-1 (ET1) and the daily rhythms of cardiac hemodynamic indices (CHI) and baroreflex (BRS) in Wistar rats with 1 kidney-1 clip model of arterial hypertension (1K-1C AH). The animals were divided into 3 groups: I- sham-operated (SO), II- 4-week and III- 8-week 1K-1C AH rats. Plasma concentration of ET1, CGRP and EET ’s were investigated every 4 h. In conscious freely moving 1K-1C AH rats ...
