Isolated superior mesenteric artery dissection in the emergency department: A rare cause of abdominal pain

Acute onset abdominal pain constitutes a significant proportion of emergency department visits, but only a small fraction of these cases are attributable to vascular pathologies (Bauersfeld, 1947 [1]). In this case, report, we present an incidental diagnosis of Spontaneous Isolated Superior Mesenteric Artery Dissection (SISMAD). A 69-year-old man was admitted to the emergency department complaining of fever, loss of appetite, vague epigastric pain, dysuria, and a productive cough for several days. A lower extremity venous Doppler ultrasound was performed, and a deep venous thrombosis (DVT) was identified in the left main femoral vein and in the proximal segment of the superficial vein. The patient also had no blood flow in the distal part of left external iliac vein. A contrast-enhanced computerized tomography angiography of the thorax and abdomen was performed to detect pulmonary embolism and the etiology of the abdominal pain. No pulmonary embolism was found; however, multiple metastatic nodules were identified in both lungs, as well as infiltration on the posterobasal field of the right lung, metastases on the liver, focal dilatation, and an intimal flap on the middle-distal part of the superior mesenteric artery (SMA) at 2?cm, with a segment that was compatible with isolated dissection. There was a contrast passage on the distal part of SMA, and no sign of bowel ischemia.     

The HAS-Choice study: Utilizing the HEART score,an ADP,and shared decision-making to decrease admissions in chest pain patients

Objective

The HAS-Choice pathway utilizes the HEART Score, an accelerated diagnostic protocol (ADP), and shared decision-making using a visual aid in the evaluation of chest pain patients. We seek to determine if our intervention can improve resource utilization in a community emergency department (ED) setting while maintaining safe patient care.

Timing of Cholecystectomy in Acute Cholecystitis

Background

Cholecystitis is an inflammation of the gallbladder that most commonly occurs as a result of obstruction of the cystic duct by gallstones. The current standard of treatment for acute cholecystitis is cholecystectomy.

Point-of-Care Ultrasound Diagnosis of Proximal Hamstring Rupture

Background

Acute proximal hamstring ruptures can be a diagnostic challenge in the emergency department. The revealing sign of large posterior thigh ecchymosis is typically not yet present; the physical examination is limited due to pain, radiographs can be unremarkable, and definitive testing with magnetic resonance imaging is not practical. These avulsions are often misdiagnosed as hamstring strains and treated conservatively. The diagnosis is made after failed treatment, often months after the injury. Surgical repair at that time can be technically challenging and higher risk due to tendon retraction and adhesion of the tendon stump to the sciatic nerve.

The Treatment of Acute Pain in the Emergency Department: A White Paper Position Statement Prepared for the American Academy of Emergency Medicine

Background

Pain is one of the most common reasons patients present to the emergency department (ED). Emergency physicians should be aware of the numerous opioid and nonopioid alternatives available for the treatment of pain.

消退素D2对椎间盘突出所致根性神经痛的作用

目的 观察消退素D2（RvD2）对非压迫性腰椎间盘突出症所致根性神经痛模型大鼠的影响。 方法 选取雄性Sprague-Dawley(SD)大鼠36只,按随机数字表法分为假手术组,模型组和RvD2组,每组大鼠12只。模型组和RvD2组均采用自体髓核组织填充法制作非压迫性腰椎间盘突出症模型,假手术组仅暴露相应手术部位,不作其它处理。造模成功后连续3d对假手术组和模型组均鞘内给予磷酸盐缓冲液（PBS）10μl,RvD2组则鞘内给予RvD2溶液10ng/10μl。于造模前1d和造模成功后连续7d观察3组大鼠术侧的50%缩足阈值（PWT）,并于造模成功后第7天获取大鼠术侧L4至L6节段脊髓背角,采用蛋白质印迹法测定磷酸化的蛋白激酶B(p-AKT),蛋白激酶B(t-AKT),磷酸化的糖原合成激酶3β(p-GSK-3β)和糖原合成激酶3β(GSK-3β)的蛋白表达量,并用酶联免疫吸附试验测定肿瘤坏死因子α（TNF-α）、白介素-6（IL-6）、转化生长因子-β1（TGF-β1）和白介素-10（IL-10）的蛋白表达含量。 结果 造模成功后第1～7天,模型组和RvD2组大鼠50%PWT与假手术组同时间点比较,差异均有统计学意义（P<0.05）;造模成功后第3～7天,RvD2组的50%PWT分别为（6.31±2.11）g、（7.37±1.58）g、（7.96±1.73）g、（8.46±1.55）g、(8.55±1.44)g,与模型组同时间点比较,差异均有统计学意义（P<0.05）。造模成功后第7天,模型组和RvD2组的p-AKT和p-GSK-3β蛋白阳性表达水平与假手术组比较,差异有统计学意义（P<0.05）;且RvD2组的p-AKT和p-GSK-3β蛋白阳性表达水平与模型组比较,差异亦有统计学意义(P<0.05)。造模成功后第7天,模型组和RvD2组大鼠脊髓背角促炎细胞因子TNF-α和IL-6以及抗炎因子TGF-β1和IL-10的蛋白表达水平与假手术组比较,差异均有统计学意义（P<0.05）; 且RvD2组促炎细胞因子TNF-α和IL-6以及抗炎因子TGF-β1和IL-10的蛋白表达水平与模型组比较,差异均有统计学意义（P<0.05）。 结论 RvD2可减轻非压迫性椎间盘突出大鼠的根性神经痛,其机制可能与抑制GSK-3β活性,下调促炎因子以及上调抗炎因子的蛋白表达水平相关。
