INTRODUCTION: Mortality after out of hospital cardiac arrest (OHCA) is high and a shockable rhythm is a key predictor of survival. A concomitant need for repeated shocks appears to be associated with less favorable outcome. AIM: To, among patients found in ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT) describe: (a) factors associated with 30-day survival with emphasis on the number of defibrillatory shocks delivered; (b) the distribution of and the characteristics of patients in relation to the number of defibrillatory shocks that were delivered...

BACKGROUND: Approximately 1% of emergency department (ED) visits are due to anaphylaxis. Symptoms can include skin rash, facial and laryngeal edema, dyspnea, vomiting, hypotension, and shock. A transient loss of consciousness can also be a manifestation of anaphylaxis. A variety of electrocardiographic changes due to anaphylaxis have been described for Kounis syndrome, also known as allergic angina. CASE REPORT: Here we describe the case of a male patient presenting at an ED with syncope, anaphylactic shock, and ST-segment elevation on electrocardiogram (ECG)...

Phenylephrine (PE) causes vasoconstriction through alpha adrenergic receptors. PE-induced vasodilatation has also been reported earlier in pre-constricted vessels. Here we demonstrate in spiral strips of goat arteries that addition of PE can decrease tone even from base-line levels (i.e. not pre-constricted) and show that this process requires nitric oxide (NO) and alpha adrenergic stimulation, but is cGMP-independent. Under control conditions, PE caused vasoconstriction, but under conditions where NO levels are higher, as with L-Arginine or sodium nitroprusside, PE decreased vessel tension...

We report here a case of rocuronium-induced anaphylactic shock in a 41-year-old woman. She was scheduled for partial hepatectomy due to liver metastasis of a pheochromocytoma. Anesthesia was induced with propofol, remifentanil, and rocuronium. Bag-mask ventilation was difficult, and her blood pressure fell to around 40 mmHg just after induction. Subsequently, her trachea was intubated and adrenaline was injected. However, due to the subsequent persistence of severe hypotension and hypoxia, cardiopulmonary resuscitation was necessary...

BACKGROUND: We often administer adrenaline to improve hypotension of patients undergoing systemic inflammation that is not treated with volume resuscitation. The effects of adrenaline on injured lungs during shock status have not been elucidated. We previously demonstrated that hepatic ischemia-reperfusion followed by high-tidal-volume ventilation-induced systemic inflammation, hypotension, and lung injury in rats. Using this animal model, we investigated the effects of adrenaline on lung injury and hemodynamics...

Hypertensive emergency usually appears in older patients with previous recurrent episodes, and is among the most frequent admissions to emergency departments. A 29-year-old woman was referred to our clinic with the diagnosis of hypertensive emergency. The patient complained of severe headache, dyspnea, palpitation, diaphoresis, and confusion due to hypertensive encephalopathy. Her blood pressure was 250/150 mmHg on admission. At the referral hospital, the patient had undergone cranial CT because of her confused state and this excluded acute cerebral hemorrhage...

BACKGROUND: Cardiomyopathy, cardiogenic shock or acute pulmonary oedema are well recognised complications of scorpion sting envenomation occurring in about 1-3% of patients. Current treatment recommendations include afterload reduction using prazosin and improving cardiac contractility with inotropes like dobutamine. We report the use of intra-aortic balloon pump (IABP) as rescue therapy in a patient with refractory cardiogenic shock due to Mesobuthus tamulus (Indian red scorpion) envenomation...

INTRODUCTION: Cardiorespiratory arrest outside hospital occurs in approximately 1/10,000 children per year in resource-rich countries, with two-thirds of arrests occurring in children under 18 months of age. Approximately 45% of cases have undetermined causes, including sudden infant death syndrome. Of the rest, 20% are caused by trauma, 10% by chronic disease, and 6% by pneumonia. METHODS AND OUTCOMES: We conducted a systematic overview, aiming to answer the following clinical question: What are the effects of treatments for non-submersion out-of-hospital cardiorespiratory arrest in children? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2014 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview)...

We present a case of hyperfibrinolysis induced by oxaliplatin-derived anaphylactic shock, which was diagnosed with rotational thromboelastometry (ROTEM). A 57-year-old male patient underwent a second course of oxaliplatin (126 mg/m/course)-based chemotherapy for stage IV metastatic rectal cancer. Two minutes after the infusion of oxaliplatin, the patient lost consciousness and developed generalized urticarial lesions, followed by hemodynamic instability and respiratory insufficiency. He was diagnosed anaphylactic shock and transported to emergency department (ED) after intramuscular injection of 0...

Wheat-dependent exercise-induced anaphylaxis (WDEIA) is often reported in adults for whom the specific IgE to ω-5 gliadin can be a useful diagnostic test. However, few cases of WDEIA in children have been reported. We herein report six cases (aged 7-16 years) of children with WDEIA, who had no clinical history of immediate-type wheat allergy but who were diagnosed by a wheat ingestion + exercise provocation test. The specific IgE to wheat ranged <0.35-3.49 (median 1.64) UA/ml. Skin prick tests using wheat extract were performed on 3 patients who showed either a negative or low specific IgE titer to wheat, and all of them resulted in negative findings...

INTRODUCTION: Stress-induced cardiomyopathy (Takotsubo) after bee stings in patients who have received catecholamines is rare. Endogenous as well as exogenous administration of catecholamines is thought to trigger stress-induced cardiomyopathy. CASE PRESENTATION: A 37-year-old healthy white woman was stung by an unknown Hymenoptera that resulted in an anaphylactic reaction. Intravenous adrenaline (0.9 mg) was administered at a nearby clinic; she was transferred to our emergency room...

Polymyxin B-immobilized fiber column direct hemoperfusion (PMX-DHP) therapy is widely used for the treatment of severe sepsis and septic shock, and is generally performed for 2 h. Although previous studies demonstrated the efficacy of PMX-DHP therapy, it currently remains unclear whether its optimal duration is 2 h. This retrospective study analyzed 37 patients with septic shock who showed a poor clinical response to 2 h of PMX-DHP, and underwent a longer duration of this therapy. The mean duration of PMX-DHP therapy was 15...

Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a rare, but potentially severe food allergy exclusively occurring when wheat ingestion is accompanied by augmenting cofactors. It is clinically characterized by anaphylactic reactions ranging from urticaria and angioedema to dyspnoea, hypotension, collapse, and shock. WDEIA usually develops after ingestion of wheat products followed by physical exercise. Other cofactors are acetylsalicylic acid and other non-steroidal anti-inflammatory drugs, alcohol, and infections...

Different environmental factors (i.e., toxins, heavy metals, ultraviolet (UV) rays, and X-radiation) cause damage to DNA, cell membranes and other organelles and induce oxidative stress, which results in the excessive production of reactive oxygen species (ROS) by phagocytes. All types of cell stress are accompanied by the activation of anti-stress genes that can suppress ROS synthesis. We hypothesized that different environmental factors would affect organisms through the activation of anti-stress genes by autologous serum (AS) proteins, followed by the synthesis of molecules that increase cell resistance to oxidative stress...
