BACKGROUND: Acute pancreatitis may cause massive intra-abdominal bleeding as vascular complications caused by the erosion of a major pancreatic or peripancreatic vessel. In terms of treatment, the differentiation between arterial bleeding and venous bleeding using abdominal computed tomography (CT) angiography is important. In addition, hypovolemic shock caused by bleeding from the inferior mesenteric vein (IMV) in acute pancreatitis has not been reported. CASE REPORT: A 58-year-old man presented to our emergency department with complaints of abdominal pain of 10 hours' duration...

Idiopathic systemic capillary leak syndrome (ISCLS) is a rare disease that involves the endothelium and microcirculation, leading to an abrupt shift of fluids and proteins from the intravascular to the interstitial compartment. The consequence of the capillary leakage is a life-threatening hypovolemic shock that can lead to lethal multiple organ dysfunction. The autonomic nervous system (ANS) is central in regulating the cardiovascular response to hypovolemia, but ANS modulation in ISCLS has not yet been investigated...

BACKGROUND: Previous studies on the recombinant form of human relaxin-2 (serelaxin) have shown a decrease of pulmonary hemodynamics after serelaxin injection. Currently, the effect of serelaxin treatment during hypovolemia in a large animal model remains mostly unknown. METHODS: 12 sheep were randomly assigned to a sham or serelaxin (30μg/kg serelaxin) group and underwent right heart catheterization. 50% of the estimated total blood volume were removed to induce hypovolemia, and subsequently retransfused 20 min later (reinfusion)...

Atraumatic tension hemothorax is extremely rare. We report a case of 62-year-old woman presented with obstructive and hypovolemic shock status by tension hemothorax due to ruptured aneurysm of congenital intercostal artery-azygous fistula. Contrast-enhanced computed tomography and aortography revealed an aberrant 12th intercostal artery flowing into the aneurysm with a fistula draining into the azygous vein and the rupture of aneurysm. Our experience indicates that the rupture of congenital arteriovenous fistulas (AVFs) of systemic circulation in the thoracic cavity might cause not only hypovolemic shock but also atraumatic tension hemothorax...

Patients with cardiac disease have high mortality rates, mainly owing to shock. Therefore, evaluation of cardiac function is one of the most challenging issues in the intensive and critical care unit. Cardiac point-of-care tests using ultrasound, such as focus assessed transthoracic echo (FATE) and rapid ultrasound in shock (RUSH). are useful for diagnosis and initial care of such patients. The author will introduce first a basic FATE protocol of how to scan from position 1-4, including subcostal 4-chamber, apical 4-chamber, parasternal long and short axis, and pleural scanning...

Sheehan's syndrome remains a frequent obstetric complication with an uncertain pathophysiology. We aimed to assess the incidence of hypopituitarism (≥2 hormonal axis impairment) within the first six postchildbirth months and to determine the existence of anti-pituitary antibodies. From 2015 to 2017, adult pregnant women, who developed moderate to severe postpartum hemorrhage (PPH), were consecutively included in the study. Pituitary function was assessed 4 and 24 weeks after PPH. At the end of the study, anti-pituitary antibodies were assessed...

Shock, a state of inadequate oxygen delivery to tissues resulting in anaerobic metabolism, lactate accumulation, and end-organ dysfunction, is common in children in emergency department. Shock can be divided into 4 categories: hypovolemic, distributive, cardiogenic, and obstructive. Early recognition of shock can be made with close attention to historical clues, physical examination and vital sign abnormalities. Early and aggressive treatment can prevent or reverse organ dysfunction and improve morbidity and mortality...

Patients with Addison's disease are at greater risk of having reduced bone mineral density and hip fractures and are thus more likely to receive a bisphosphonate than their peers. Potent intravenous bisphosphonates could provoke an acute phase reaction. An 80-year-old female with Addison's disease received her first infusion of zoledronic acid for osteoporosis at our outpatient clinic around noon. Despite doubling her usual afternoon hydrocortisone dose, she became feverish, nauseous, extremely weak, and hypotensive over the night...

BACKGROUND: Pulmonary arteriovenous malformations are rare vascular abnormalities that permit direct communication between the pulmonary artery and vein. During pregnancy, pulmonary arteriovenous malformation carries an increased risk of enlargement and rupture, which could lead to life-threatening hemothorax. This is the first case reporting successful thoracoscopic surgery for a pregnant woman with pulmonary arteriovenous malformation rupture-related hemothorax. CASE PRESENTATION: We present a case of a 32-year-old pregnant Asian woman (31 weeks' gestation) whose pulmonary arteriovenous malformation ruptured, leading to right-sided spontaneous tension hemothorax...

OBJECTIVE: When objectively measured on computed tomography (CT), does hepatic heterogeneity or overall liver attenuation predict the presence of shock? METHODS: This retrospective study included 73 patients (mean age 33 years) with the hypoperfusion shock complex (HSC) on CT (cases) and 100 patients (mean age 43 years) with negative trauma CT scans (controls). Liver heterogeneity was calculated by using consistently sized regions of interest (ROIs) to measure the 2 highest and the 2 lowest areas of hepatic density (in Hounsfield units [HU])...

Emmanuel Ademola Anigilaje
The survival of a child with severe volume depletion at the emergency department depends on the competency of the first responder to recognize and promptly treat hypovolemic shock. Although the basic principles on fluid and electrolytes therapy have been investigated for decades, the topic remains a challenge, as consensus on clinical management protocol is difficult to reach, and more adverse events are reported from fluid administration than for any other drug. While the old principles proposed by Holliday and Segar, and Finberg have stood the test of time, recent systematic reviews and meta-analyses have highlighted the risk of hyponatraemia, and hyponatraemic encephalopathy in some children treated with hypotonic fluids...

INTRODUCTION: Gastrointestinal Stromal Tumors (GISTs) are a rare slow growing malignancy, accounting for less than 1% of all gastrointestinal (GI) tract tumors. These tumors are usually discovered incidentally by endoscopy, surgery or radiology. However on occasions they may present with significant symptoms including GI blood loss. This case report discusses an atypical presentation of a GIST in a 57-year-old female. CASE PRESENTATION: A 57-year-old woman presented to the emergency department following one episode of melena...

NEW FINDINGS: What is the central question of this study? Collagen-binding β1 -integrins function physiologically in cellular control of dermal interstitial fluid pressure (PIF ) in vivo and thereby participate in control of extravascular fluid volume. During anaphylaxis, simulated by injection of Compound 48/80 integrin αV β3 takes over this physiological function. Here we addressed the question whether integrin αV β3 can replace collagen-binding β1 -integrin to maintain a long-term homeostatic PIF ...

BACKGROUND AND OBJECTIVES: In severe circulatory failure agreement between arterial and mixed venous or central venous values is poor; venous values are more reflective of tissue acid-base imbalance. No prior study has examined the relationship between peripheral venous blood gas (VBG) values and arterial blood gas (ABG) values in hemodynamic compromise. The objective of this study was to examine the correlation between hemodynamic parameters, specifically systolic blood pressure (SBP) and the arterial-peripheral venous (A-PV) difference for all commonly used acid-base parameters (pH, Pco2 , and bicarbonate)...
